Abstract
Abstract A lure for schooling greyhounds is provided with an electrode to which pulses of voltage are applied, and with apparatus for emitting sounds from the lure. The sounds attract the greyhound's attention and the electrical stimulation he receives when he touches the lure cause the greyhound to attack the lure and to achieve satisfaction from it. The electrical pulse generating circuitry and sound source are separate from the lure and releasable connections are provided to enable the lure and electrode to be replaced by a fresh one if damaged, without also having to replace the circuitry and sound source.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
71 words
Greyhound conditioning apparatus, comprising a lure, an electrode on said lure, an electrical power source, and circuit means energised by said source and connected to said electrode whereby a greyhound attacking the lure receives from said electrode an electrical "fight-back" stimulus of sufficiently short time duration not to shock or frighten a greyhound but rather to stimulate the greyhound to attack the lure in the belief that said lure is alive.
Claim 2
Dependent Claim
71 words
Greyhound conditioning apparatus, comprising a lure, an electrode on said lure, an electrical power source, and circuit means energised by said source and connected to said electrode whereby a greyhound attacking the lure receives from said electrode an electrical "fight-back" stimulus of sufficiently short time duration not to shock or frighten a greyhound but rather to stimulate the greyhound to attack the lure in the belief that said lure is alive.
Claim 3
Dependent Claim
19 words
Apparatus as set forth in claim 1, including sound generating means to attract the greyhounds attention to the lure.
Claim 4
Dependent Claim
49 words
Apparatus as set forth in claim 2, in which the sound generating means comprises a hollow, open-ended tube connected at one end to a sound source remote from the lure and having its other end on the lure, a part of said electrode being positioned adjacent said other end.
Claim 5
Dependent Claim
70 words
Apparatus as set forth in claim 3, in which the tube provides a flexible mount for the lure and is made from an insulative material, said tube being releasably connected to a nozzle on a mount which carries said power source and said electrical circuitry, a loud-speaker arranged to direct to direct sound into the nozzle and disconnectable electrical means on said pipe connecting said electrode to said electrical circuitry.
Claim 6
Dependent Claim
90 words
Greyhound conditioning apparatus comprising a lure, a padding on said lure, a removeable sheath on said padding, an electrode beneath said sheath, openings defined by said sheath and through which said electrode is partially exposed, an electrical power source, circuit means electrically connected between said power source and said electrode, and sound generating means energised from said power source whereby the sounds generated attract a greyhounds attention to the lure and electrical stimulus received from the electrode when the greyhound touches the lure encourages the greyhound to attack the lure.
Claim 7
Dependent Claim
90 words
Greyhound conditioning apparatus comprising a lure, a padding on said lure, a removeable sheath on said padding, an electrode beneath said sheath, openings defined by said sheath and through which said electrode is partially exposed, an electrical power source, circuit means electrically connected between said power source and said electrode, and sound generating means energised from said power source whereby the sounds generated attract a greyhounds attention to the lure and electrical stimulus received from the electrode when the greyhound touches the lure encourages the greyhound to attack the lure.
Claim 8
Dependent Claim
41 words
Apparatus as set forth in claim 5, in which said sheath has an open end, a part of said electrode is located within said open end, and said sound generating means produce sounds which appear to emanate from said open end.
Claim 9
Dependent Claim
32 words
Apparatus as set forth in claim 6, in which said electrode has at least one tuft electrode branching from it through said sheath and splayed out on the outside of said sheath.
Claim 10
Dependent Claim
98 words
Apparatus as claimed in claim 7, including an insulative open-ended pipe having said padding fixed on one end-portion the end of which lies within the open end of said sheath, the other end-portion of said pipe projecting from a second end of said sheath to provide a resiliently flexible mount for said lure, a releasable means connecting the other end of said pipe to receive sound signals from a loudspeaker remote from said sheath, and an electrical lead extending from a releasable connector at said other end of said pipe, into said pipe and connected to said electrode.
Claim 11
Dependent Claim
127 words
Greyhound conditioning apparatus comprising a lure, an electrode on said lure, a mount for said lure and spaced therefrom, an electrical power source on said mount, a housing on said mount, electrical circuitry in said housing energisably connected to said power source, first electrical connections extending from said circuitry to the electrode on said lure, a loudspeaker on said mount, second electrical connections extending from the electrical circuitry to said loudspeaker, a flexible open-ended tube extending from said lure to said mount, releasable connection means attaching said tube to said mount at the position of said loudspeaker, and a portion of said electrode disposed adjacent the end of said tube remote from said mount, and further portions of said electrode exposed on the outside of said lure.
Claim 12
Dependent Claim
127 words
Greyhound conditioning apparatus comprising a lure, an electrode on said lure, a mount for said lure and spaced therefrom, an electrical power source on said mount, a housing on said mount, electrical circuitry in said housing energisably connected to said power source, first electrical connections extending from said circuitry to the electrode on said lure, a loudspeaker on said mount, second electrical connections extending from the electrical circuitry to said loudspeaker, a flexible open-ended tube extending from said lure to said mount, releasable connection means attaching said tube to said mount at the position of said loudspeaker, and a portion of said electrode disposed adjacent the end of said tube remote from said mount, and further portions of said electrode exposed on the outside of said lure.
Claim 13
Dependent Claim
126 words
Apparatus as set forth in claim 9, in which the electrical circuitry includes a counting unit which records each time the lure is turned on, the circuitry is arranged to energy the loudspeaker to produce bleeps of sound of substantially constant amplitude and which sweeps, in each bleep, upwardly through a range of frequencies from 700Hz to 1000Hz, the bleep repetition rate is between 1Hz and 11/2Hz, the circuitry energizes the lure electrode with spikes of voltage between 40 volts and 150 volts with a repetition rate of between 1Hz and 2Hz, the duration of each voltage spike is substantially 0.3 milliseconds, and manually operable controls enable the electrical characteristics of the pulses fed to the electrode to be altered to suit the greyhound being conditioned.
