Title: Binary divider
IPC: G06F7/508
Filed: 1973-07-16
Abstract: 1433833 Digital dividers BURROUGHS CORP 16 July 1973 [14 Dec 1972] 33703/73 Heading G4A In each iteration a binary non-restore divider calculates a partial remainder by subtracting a multiple of the divisor from a multiple of the preceding remainder. During the same iteration the next two bits of the quotient are predicted by reference to the multiplier of the divisor, the preceding remainder, and the divisor. The predicted bits are subsequently corrected by reference to the signs of the preceding and the presently calculated remainders. Adder 15, Fig. 1, receives as input a value of four times the preceding remainder R (or the normalized dividend in the first iteration) from E register 11 and a multiple, -MD, of the normalized divisor D from F register 13. The output (4R-MD) of the adder is the present partial remainder R<SP>1</SP>. It is placed in R register 17, and also multiplied by 4 by shifting left two places in E register 11 for use in the next addition iteration. While this addition is occurring, the preceding remainder R is read from register 17 to Q table decoder 19 which also receives the divisor D. The output of decoder 19 depends upon the five or six most significant bits of the divisor and remainder and is a prediction of the multiplier to be used in the next iteration. Its output is fed to decoder 21 which also receives from register 23 the preceding predicted two quotient bits. Decoder 21 confirms or corrects the multiplier and enables a corresponding multiplier gate 25, 27, 29. It also enables a corresponding quotient gate 31, 33, 35 to pass a present predicted 2-bit quotient having value 01, 10 or 11. The relevant predicted value is passed to Q register 23, and the corresponding multiple of the divisor is placed in F register 13 for use in calculating the next remainder. The predicted quotient value may be one greater than the correct value and it is corrected at 39 by reference to the signs of the present remainder R<SP>1</SP> and the preceding remainder R. The corrrected quotient bits pass to D register 41 in which the complete quotient is built up during successive iterations.

Title: Improvements in or relating to coin controlled vending machines adapted to give change
IPC: G07F5/24
Filed: 1937-12-14
Abstract: 503,257. Coin - controlled vending- machines with change-giving. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and DOLMAN, H. J. Dec. 14, 1937, No. 34523. [Class 27] In a coin-controlled vending-machine wherein coins after effecting operation of the machine to deliver an article are fed to a change magazine from which they arc ejected as change, when the machine is actuated by a coin of higher value, one or more reserve magazines are provided from which coins are automatically fed to the change magazine in time to prevent a breakdown in the ejection of the proper change due to the change magazine becoming ex - hausted. As applied to a machine arranged to deliver a ticket for seven pennies, or a ticket and five pennies in exchange for one shilling, the pennies finally pass by a shoot 1 to a change magazine 5, while a shilling passes down a shoot 3 and rocks a feeler 10 to close contacts 12, 13 and momentarily energize a solenoid 14. The solenoid rocks a lever 16 against the action of a spring 15 to free a slide 18 which is moved by a spring 19 to eject five pennies as change from the magazine 5 to a delivery shoot 30. If there are less than five pennies in the magazine 5, a feeler 20 moves into the magazine and closes contacts 22, 23 to energize a solenoid 24, thereby releasing a slide 28 which ejects three pennies from a reserve magazine 31 and two from a second reserve magazine 32. These coins pass by shoots 33, 34 to replenish the magazine 5. The slides 18, 28 are reset from the mechanism effecting the ticket delivery. For example, the delivery mechanism includes a disc 35 rotating in a clockwise direction. A pin 36 on this disc actuates levers 37, 38 to reset the slides. The feeler 20 may be set at a higher position 20<1> on the magazine 5 to ensure the replenishment of the latter in good time ; the feeler actuating contacts 22<1>, 23<1>. In a modification, in order to conserve the coins in the reserve magazines, their delivery is also made dependent on the insertion of a shilling as well as exhaustion of the magazine 5. Another feeler 50 actuated by the shilling is provided, the contacts 52, 53 closed by this feeler being in series with the contacts 221, 231 so that the solenoid 24 is not energized unless both sets of contacts are closed.

Title: Critical temperature resistor device
IPC: H01C7/04
Filed: 1964-08-24
Abstract: 1,083,314. Temperature-sensitive resistors; circuit assemblies. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Aug. 24 1964 [Aug. 22 1963; Feb. 19 1964; April 1 1964 (2)] No. 34574/64. Headings H1K and H1R. A critical temperature thermistor (i.e. one having a greater variation of resistance over a particular temperature range) comprising a bead of a mixture of vanadium oxide and a basic metallic or an acidic oxide in which are embedded two or more leads arranged to concentrate the electric field in the body produced by a voltage applied to the leads on at least a particular spot of one of the leads. The electrodes may be arranged end to end or parallel to one another with their ends embedded in the bead. Alternatively the electrodes may be arranged at right angles with one passing through the bead and the other terminating inside the bead, or both passing through the head but arranged in different planes. As shown, Fig. 11, a bi-stable element may be produced by embedding four platinum electrodes 12, 13, 14, 15 in a bead 4 of thermistor material. When connected in a suitable circuit, Fig. 12 (not shown) the low resistance region can be switched from between electrodes 12, 13 to between electrodes 12, 15 and back again by applying pulses to electrode 14. A scaling circuit using a plurality of such elements is described, Fig. 14 (not shown). Platinum and palladium electrodes are mentioned. Circuit assemblies.-When placed in parallel with a 30 pF capacitor and fed through a resistor from an A.C. or pulsed D.C., source the thermistors are said to produce bursts of high frequency oscillation (10 kc/s. to 1 Mc/s.). As shown, Fig. 9, this circuit may be constructed from a resistor R surrounded by two conductive layers 5, 7 separated by a dielectric layer 6 to form the capacitor. A thermistor 1 is connected between the layers 5, 7 and one terminal of resistor R is connected to layer 7. The input supply is applied to conductors 8, 8a. A further dielectric layer (6a) and a conductive layer (11) may surround layer 7 to form a capacitor to block the low frequency supply from the output, Fig. 10 (not shown). The device may be used as a pulse generator or signal injector or to sense temperature, e.g. to measure air temperature or air velocity. If connected in a similar circuit but with a D.C. supply the thermistor produces a sweep oscillation.
