Title: Counters
IPC: G06K15/16
Filed: 1975-09-18
Abstract: 1482038 Counting electric pulses INTERNATIONAL BUSINESS MACHINES CORP .18 Sept 1975 [17 Dec 1974] 38297/75 Heading G4D Means are provided for counting all the transitions of two out of phase binary signals A,. B from the commencement of an asynchronously occurring start signal. The two binary signals A, B are first combined in an exclusive- OR gate 15 to form a signal C having all the transitions of A and B. The single signal C is applied to a latch circuit 30 which records the state of signal C at the appearance of the start signal and uses it as the reference level for a pulse train derived from signal C and which is counted in a binary counter 40; by this means the first transition after the start signal is considered as the leading edge of a pulse to be counted regardless of its direction. By using the input pulse train Q 0  itself as the first bit of the count output this is effectively doubled and represents the total number of transitions that signals A, B have made. The counter is employed in a control for a stepping motor (Fig. 4, not shown) causing the motor to advance a determined number of steps for each start signal.

Title: Electronic digital weighing apparatus
IPC: G06F7/62
Filed: 1971-08-24
Abstract: 1356665 Weighing apparatus; multiplying TOKYO ELECTRIC CO Ltd 24 Aug 1971 39641/71 Headings G4H and G4A [Also in Division G1] A weighing apparatus obtains the cost of a weighed article from the price per unit weight, keyed in by the operator, and the weight measured, by a multiplication process in which for each digit of the price per unit weight the weight is repeatedly added to itself a number of times equal to the digit, the successive additions being cumulative with suitable digit shifting of the sum for successive digits of the price per unit weight. In Fig. 1 a spring balance weighing apparatus 11 drives a photo-electric displacement encoder 12 supplying up and down pulses to a counter 13, whose parallel output via converter 14 is fed serially into W-register 16. The price per unit weight is read in from a keyboard 17 to a U- register 18. Under the control of a circuit 26 the contents of the W-register are added into the P-register 20, by summing the contents of both registers 16 and 20 in adder 21 and replacing the sum in register 20, a number of times equal to the lowest significant digit (LSD) of the unit price contained in register 18. Counter 24 counts the number of additions and a coincidence detecting circuit 25 stops the addition when the counter equals the LSD of register 19 and via circuit 26 affects a shift to the right of one digit by the P and U registers and also resets counter 24. If the LSD is zero the shift is performed immediately. Counter 27 counts the number of shifts and on the maximum possible for the unit price causes control circuit 26 to read out via data selector 31 the weight, price and unit price to a set of display tubes 25 and optionally to a printer 38. The registers and counters are reset and the display terminated a predetermined time after the receipt of the digital representation of weight, although a key is provided to maintain the display if required. The weight of a tare initially placed on the weighing apparatus may be removed from the up-down counter 13 by a reset key. The digital shaft encoder (Fig. 4) comprises a disc 54 driven through a rack and pinion 55, 56 by the lever system of the weighing apparatus (see Division G1). An arm 60, mounted on the frame 50 carrying the disc, has an upper plate 62 carrying a pair of phototransistors or photodiodes 65, 66 and lower plate 64 carrying a light, which sense equally spaced slits around the periphery of the disc. A keyboard (Fig. 15) provides for each key depressed a 4-bit binary output fed serially from gates 165-168 by clock pulses t 1 -t 4 .

Filed: 1957-12-31
Abstract: 839,075. Reservoir pens. RIBAS, M. P. Dec. 31, 1957, No. 40498/57. A writing instrument comprises a feed member for a nib or ball mounted in a bushing at one end of the barrel, a pair of collapsible ink sacs mounted in parallel side-by-side relation at opposite sides of the longitudinal axis of the barrel within the barrel, the interiors of the sacs communicating in common with the feed member, and means for collapsing the sacs. The rear end of the bushing 21 is screwed into a threaded axial bore 44 in a second bushing 24 mounted non-rotatably in the barrel and having at its rear end two nipples 46 which communicate with the bore 44 by means of capillary channels 48, 48a and which carry the two ink sacs 25, the barrel 20 being of the cross-section shown in Figs. 6, 7 to accommodate the sacs. A metal strip 70 is disposed longitudinally between the two sacs and is rotatable by means of a knob 28 to which it is connected by a rod 64 rigidly secured in the knob and having a slot in which the rear end of the strip is fastened. The rod 64 is rotatable and axially slidable in a bearing member 67 mounted in the rear end of the barrel. The rear face 671 (Fig. 6) of the member 67 has a generally diagonal groove 672 cut therein and raised portions 71, 72 of substantially triangular cross-section at each end. The knob 28 has an extension 73 on its lower face, the extension having two flat and two curved lateral faces, the dimension between the flat faces corresponding to the width of the groove 672 while that between the curved faces is greater. The normal position of the strip 70 is shown by a broken line in Fig. 7 and in this position the extension 73 engages the groove 672 as shown in Figs. 3, 6, being held in that position by a compression spring 76 acting between the lower end of the member 67 and a flange 78 on a sleeve 77 surrounding the rod 64. To collapse the sacs 25 the knob 28 is pulled out against the force of the spring 76 until the extension 73 is free of the groove 672, and is then rotated through about 90 degrees in an anti-clockwise direction, further rotation being prevented by the abutment of the flat faces of the extension against the raised portions 71, 72. This causes the strip 70 to assume a position at right angles to the broken line position of Fig. 7 and thus collapse the sacs, an intermediate position of the strip being shown in full line. The feed member 22 is generally cylindrical and has an axial bore accommodating a conduit 52, and a transverse slot accommodating a flat nib 23. In normal use ink flows to the nib from both sacs simultaneously. Owing to the inclined position of the pen in the hand when in use, when ink ceases to flow to the nib the ink in one sac (the uppermost) will be exhausted and a small quantity will remain in the other sac which can be fed to the nib by the raising of the pen into a more erect position. The arrangement of the nib and feed member forms the subject-matter of Specification 839,076 and the point protecting cap and pocket clip form that of Specification 839,077.
