Abstract
Abstract The flexitime recorder has a timing pulse generator and a number of counters acting as time stores, with switches for connecting the counters to the generator so that personnel can switch on and switch off their respective counters. A correction pulse generator is provided for generating a correction pulse at a higher frequency than that of the timing pulses, and is connected to any one of the counters through a pulse train limiter and an address device, for altering the value on the counter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
A flexitime recorder comprising: timing pulse generating means for generating timing pulses at a first frequency; a plurality of pulse-actuated time store counting means for counting said timing pulses; a plurality of switch means for controlling the time registered in respective said time store counting means in accordance with the in-time of persons with whom the individual time store counting means are associated; correction pulse generating means for generating correction pulses at a frequency substantially higher than said first frequency, for transmission to a said time store counting means to correct the time registered therein; pulse train limiting means associated with said correction pulse generating means, for allowing a predetermined number of pulses to be transmitted from said correction pulse generating means to said time store counting means; adjusting means for altering said number of pulses transmitted by said pulse train limiting means; address means connected to said pulse train limiting means and said time store counting means, for permitting said correction pulses to pass to a said time store counting means; and altering means for altering said address means to permit said correction pulses to pass to a different said time store counting means.
Claim 2
Dependent Claim
195 words
A flexitime recorder comprising: timing pulse generating means for generating timing pulses at a first frequency; a plurality of pulse-actuated time store counting means for counting said timing pulses; a plurality of switch means for controlling the time registered in respective said time store counting means in accordance with the in-time of persons with whom the individual time store counting means are associated; correction pulse generating means for generating correction pulses at a frequency substantially higher than said first frequency, for transmission to a said time store counting means to correct the time registered therein; pulse train limiting means associated with said correction pulse generating means, for allowing a predetermined number of pulses to be transmitted from said correction pulse generating means to said time store counting means; adjusting means for altering said number of pulses transmitted by said pulse train limiting means; address means connected to said pulse train limiting means and said time store counting means, for permitting said correction pulses to pass to a said time store counting means; and altering means for altering said address means to permit said correction pulses to pass to a different said time store counting means.
Claim 3
Dependent Claim
43 words
The flexitime recorder of Claim 1, and further comprising means connected to said correction pulse generating means and said pulse train limiting means, and also connected to said timing pulse generating means, for suppressing any correction pulse which coincides with a timing pulse.
Claim 4
Dependent Claim
38 words
The flexitime recorder of Claim 2, wherein said pulse train limiting means comprises subtraction pulse counting means which operates by subtraction and wherein said adjusting means is for setting an initial value on said subtraction pulse counting means.
Claim 5
Dependent Claim
46 words
The flexitime recorder of Claim 2, wherein said timing pulse generating means and said correction pulse generating means comprise a crystal-controlled electronic clock and frequency dividing means having two outputs, one said output providing said timing pulses and the other said output providing the correction pulses.
Claim 6
Dependent Claim
38 words
The flexitime recorder of claim 1, wherein said pulse train limiting means comprises subtraction pulse counting means which operates by subtraction and wherein said adjusting means is for setting an initial value on said subtraction pulse counting means.
Claim 7
Dependent Claim
46 words
The flexitime recorder of claim 5, wherein said timing pulse generating means and said correction pulse generating means comprise a crystal-controlled electronic clock and frequency dividing means having two outputs, one said output providing said timing pulses and the other said output providing the correction pulses.
Claim 8
Dependent Claim
41 words
The flexitime Recorder of claim 5, and further comprising security element actuated switch means connected to said correction pulse generating means and said time store counting means for preventing unauthorised transmission of said correction pulses to said time store counting means.
Claim 9
Dependent Claim
46 words
The flexitime recorder of claim 1, wherein said timing pulse generating means and said correction pulse generating means comprise a crystal-controlled electronic clock and frequency dividing means having two outputs, one said output providing said timing pulses and the other said output providing the correction pulses.
Claim 10
Dependent Claim
41 words
The flexitime recorder of claim 8, and further comprising security element actuated switch means connected to said correction pulse generating means and said time store counting means for preventing unauthorised transmission of said correction pulses to said time store counting means.
Claim 11
Dependent Claim
41 words
The flexitime recorder of claim 1, and further comprising security element actuated switch means connected to said correction pulse generating means and said time store counting means for preventing unauthorised transmission of said correction pulses to said time store counting means.
