Abstract
Abstract A lubricating system supplies lubricant to various parts of an apparatus. An electrical pulse generator provides a signal so as to actuate the lubricating means. A blocking oscillator stores a specific number of pulses from the generator to provide a counting cycle from which the signal is produced.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
A system for lubricating apparatus having lubricating means operatively responsive to an operating signal, said system comprising: electrical pulse generator means including magnet means and magnetic flux detector means movable by an apparatus relative to each other in pulse generating relation for generating electrical pulses, and signal means for sending an operating signal to actuate said lubricating means, including a blocking oscillator which stores a specific number of pulses from said generator means to provide a counting cycle and then produces said operating signal, the signal means being resettable for the next counting cycle upon actuation of said lubricating means.
Claim 2
Independent Claim
100 words
A system for lubricating apparatus having lubricating means operatively responsive to an operating signal, said system comprising: electrical pulse generator means including magnet means and magnetic flux detector means movable by an apparatus relative to each other in pulse generating relation for generating electrical pulses, and signal means for sending an operating signal to actuate said lubricating means, including a blocking oscillator which stores a specific number of pulses from said generator means to provide a counting cycle and then produces said operating signal, the signal means being resettable for the next counting cycle upon actuation of said lubricating means.
Claim 3
Dependent Claim
31 words
A system as claimed in claim 1 including a pulse shaper positioned between the pulse generator means and the signal means for shaping the generated pulses to constant amplitude and duration.
Claim 4
Dependent Claim
29 words
A system as claimed in claim 1 in which the magnetic means and flux detector means are mutually rotatable with one positioned adjacent the circular path of the other.
Claim 5
Dependent Claim
32 words
A system as claimed in claim 3 wherein the blocking oscillator comprises a feed back transformer which is stepwise magnetized by the electrical pulses and produces an output pulses on core saturation.
Claim 6
Dependent Claim
32 words
A system as claimed in claim 4 wherein the specific number of electrical pulses stored by the feed back transformer is adjustable by variation of the steady state magnetization of the core.
Claim 7
Dependent Claim
28 words
A system as claimed in claim 4 including a monostable circuit which is triggered by the output pulse from the feed back transformer to produce an operating signal.
Claim 8
Dependent Claim
32 words
A system as claimed in claim 6 in which the feed back transformer is reset to perform another counting cycle by a reset pulse produced by an amplifier following the monostable circuit.
Claim 9
Dependent Claim
25 words
A system as claimed in claim 7 wherein the magnetic means and flux detector means are relatively movable by the transmission system of the apparatus.
Claim 10
Dependent Claim
134 words
A vehicle lubrication system comprising: a magnet attached to a moving part of the vehicle; a magnetic pickup attached to a nonmoving part of the vehicle; a pulse shaper operatively connected with said pickup for shaping the pulses produced b the pickup; a feed back transformer operatively associated with said pulse shaper and which is stepwise magnetized by pulses from the pulse shaper to give an output pulse for a specific number of input pulses; a monostable circuit operatively connected to said transformer and triggered by an output pulse from the transformer; an output amplifier connected to amplify pulses received from the monostable circuit and to supply an operating signal; and a signal response lubricating means connected to said output amplifier, the feedback transformer being reset by a reset pulse emitted by the amplifier.
