Title: Thin sheet sorting apparatus
IPC: G07D11/00
Filed: 1981-10-08
Abstract: A bundle of sheets is supplied from a sheet supply device (100) to a sheet transfer device (200), which then transfers sheets one by one to a sheet inspection device (300). The sheet inspection device (300) makes optical, magnetic, and mechanical inspections of the sheet transferred thereto to identify valid sheets, soiled sheets, first unidentifiable sheets, or second unidentifiable sheets in accordance with the results of the inspections. Counters count the valid sheets, soiled sheets, and first unidentifiable sheets, and the sum total of these counted sheets is compared with a set value. If the sum total of the sheets agrees with the set value, a subsequent bundle of sheets is automatically supplied from the supply device (100) to the sheet transfer device (200). The number of second unidentifiable sheets (eg superposed sheets, folded sheet, etc), if any, are detected by the sheet inspection device (300) and are counted manually, and the count number obtained is added to the sum of the numbers of the valid and soiled sheets. Then, the value obtained by such addition is compared with the set value before sorting is recommenced. The sheets can be slips, cheques, securities etc. The arrangement reduces the number of key operators by the machine operator and enables sorting to be performed continuously if no second unidentifiable sheet types are counted. <IMAGE>

Patent GB-2093286-A (GB)
Title: Sequential Detonation of Explosions
IPC: F42D1/055
Filed: 1982-02-08
Abstract: Activating modules 10 are connected in parallel at 30, 32 across the output of a shot exploder (52, Fig. 2, not shown) which supplies a series of calibrating signals. The first calibrating signal calibrates the first module in the series and successive calibrating signals calibrate successive modules. After each module has been calibrated it supplies a mode switching signal to module, so that the said next module responds to the next calibrating signal and is calibrated by it. Each module has an internal oscillator (14), a calibrating counter (22), a timing counter (20) and a comparator (24). The timing signals of the oscillator (14) are routed to the counters (20, 22) via gates (16, 18). A mode control section (42) supplies a calibration mode signal to the gate (18) and a timing mode signal to the gate (16) so that the signal from oscillator (14) are counted, in counter (22), (20) during a calibration mode and a timing mode respectively. The mode control section (42) supplies the calibration mode signal when it receives a mode switching signal at an input terminal (40) and a calibrating signal from the shot exploder via a pulse discriminator (34). The timing mode signal is supplied at the end of the calibrating signal, a mode switching signal being then also supplied to the next module via an output terminal (50). In the timing mode, the count of the timing counter (20) is compared by a comparator (24) with the count accumulated in the calibrating counter (22) during the calibrating mode. When the counts are equal the comparator (24) adds one to the count of a delay counter (26) and resets counter (20) to start counting from zero again. When the delay counter (26) has a count of 32 an activating signal is supplied to the detonator connected to that module via terminal (28). The successive calibrating signals may have different deviations so that the corresponding counter (26) produce different delays. <IMAGE>
