Title: Improvements in or relating to cash registers, accounting machines, calculating machines and similar machines
IPC: G06C7/10
Filed: 1931-07-06
Abstract: 381,239. Cash registers &c. NATIONAL CASH REGISTER CO., Ltd. and LUPTON, A. S., 225, Tottenham Court Road, London. July 6, 1931, No. 19390. [Class 106 (i).] Splitting machine ; printing totals.-In a cash register or calculating-machine having a keyboard split into an adding section and a printing and/or indicating section, overflow pinions for the totalizer or totalizers are situated in rear of the printing banks but normally to one side of the planes of the actuators for those banks. The transfer sectors are offset from the actuators so as to cooperate with the overflow pinions but for total-taking the whole of the'pinions constituting the totalizer are shifted axially to register with all the differential actuators. The invention is illustrated as applied to the machine described in Specification 8119/15, [Class 106 (i), Calculating &c.], Fig. 5 shows the application to a single totalizer 290, the five right-hand pinions of which are adapted to be actuated bv the usual differential racks 288. The four left-hand pinions are however normally to one side of the corresponding actuators that are provided for setting the printing and/or indicating elements. On these latter actuators are mounted, laterally displaced, the usual transfer sectors 289, Fig. 4, so that amounts overflowing from the fifth pinion may pass by way of these sectors to the left-hand pinions. Similarly in the case of a multiple-totalizer line shown in Fig. 6 the various overflow pinions are, in adding operations, never in the planes of the actuators but selectively stand in the planes of the transfer sectors to receive any overflows. In order to take a total the totalizer or totalizers must be axially shifted to bring the overflow pinions into co-operation with the actuators, the other totalizer pinions being sufficiently broad to maintain co-operation with their actuators. This shifting may be performed directly by the adjustment of the total lever but in another arrangement it is derived from the control bank as follows. The totalizer keys 701, Fig. 2, select the totalizer to be engaged but if the total-lever is moved to a total or sub-total position it moves a detent 711 upwards to remove slots 710 from the paths of pins 709 on levers 706 pivoted on the keys. The other ends of these levers bear on pins 707 on auxiliary key-stems 702 situated one step. below the corresponding keys. With the detent thus displaced the pins 709 are blocked so that depression of a key operates the auxiliary stem to break the differential latch slightly sooner in its travel. The totalizer-selecting cam 599, Fig. G, therefore not only selects the totalizer but places it in its total-yielding position.

Filed: 1965-05-08
Abstract: 1,082,263. Preventing backward movement of mechanisms. BIRFIELD ENGINEERING Ltd. Sept. 17, 1965 [May 8, 1965], No. 19499/65. Heading F2E. In an anti-runback safety device for use with mechanism driven by an endless flexible driving member such as a belt drive 3 and liable to undergo reverse rotation on failure of the flexible driving member, a peripherally notched circular member driven by the driven pulley 4 is adapted to be engaged by a pawl 23 of a two-armed pawl lever 8 whenever the flexible driving member 3 fails, the pawl lever being provided with a roller 21 which normally rests on the upper run of the belt drive 3 to move the pawl out of engagement with the notched circular member. The driving member 1 is an electric motor and the driven pulley 4 is mounted on the input shaft 5 of a driven part 6 of a gear-box having an output shaft 7. In order to prevent abrupt cessation of rotation of the pulley 4 in the event of failure of the flexible drive 3, a friction device is mounted between the notched circular member 9 and the flat web portion 10 of the pulley 4 (Fig. 2, not shown), the degree of braking being controlled by the pressure provided by two dished spring washers the pressure of which can be regulated by turning a nut. To ensure that the roller 21 is so supported as to keep the pawl 23 clear of the notches 15 so long as the belt drive remains effective, a roller 26 carried by a pivot 27 extends from the gear-box 6 and is disposed under the upper run of the belt drive.

Abstract: 1370513 Refrigeration; heat exchangers H STIERLIN 28 April 1972 [7 May 1971] 19766/72 Headings F4H and F4S In a continuous cycle adsorption refrigeration system operating with an inert auxiliary gas comprising a generator 1, Fig. 4, condenser 2, evaporator 20, gas heat exchanger 18, absorber 6 and reservoir 7, the gas heat exchanger comprises a first set of passages A1, B1...D1, Fig. 5 through which the refrigerant-lean gas from the absorber is conducted into the evaporator 20 and the refrigerant-rich gas is conducted from the evaporator through the heat exchanger by a second set of passages A2, B2... D2. Each passage of the first set communicates with a respective passage of the second set through openings 23 in a common dividing wall 30 but is isolated from the remaining passages of the second set except that which is radially adjacent thereto. Condensed refrigerant is introduced into the evaporator as a capillary layer formed on the internal surface of the wall 26 of the evaporator and continues to flow downwardly through the heat-exchanger in contact with the flow of auxiliary gas which is thereby enriched in refrigerant. The efficiency of such apparatus enables deep freeze temperatures to be achieved at the evaporator. In a modification the heat exchanger may be formed by concentric pipes, Figs. 6, 7 or the heat exchanger may be formed by nesting corrugated sheets of differing heights of corrugations with a third, planar sheet closing the open sides of the smaller corrugations.

Title: A new or improved machine for severing lengths of endwise moving stock
IPC: B23D45/18
Filed: 1947-07-24
Abstract: 627,916. Sawing. BARTON CONDUITS, Ltd., and PRICHARDS, A. July 24, 1947, No. 19937. [Class 145(ii)] A sawing machine for severing endwise moving stock, e.g. metal tube emerging from a tube rolling machine, comprises a carriage reciprocably mounted on a support, a severing tool mounted or the carriage for movement transverse to the stock pneumatic means for reciprocating the carriage and means for moving the tool transversely, the carriage being moved forwardly by pneumatic pressure and completing its return against said pressure so that in its starting position the carriage is under load tending to urge it forwardly; together with a device releasable by the stock for retaining the carriage against forward motion until released by the operation of the said device by the stock, whereupon the carriage is accelerated quickly to the speed of the stock. The carriage 12, sliding on the base 10 and carrying a motor-driven saw 17, is held stationary by a latch 64 which is under load due to air pressure in the cylinder 5. Moving stock 40 actuates a trip device 74 on the receiving table 41 (see Fig. 2 not shown) which via rod 68 releases the latch 64, the carriage 12 thus moving forwardly. The cam B, adjustable in guides 75 on the side of the carriage, then strikes the arm 58 pivoted at 9 to operate an air valve X admitting air to cylinders 50 to close grippers 48 on the stock so synchronising the carriage and tube speeds. A roller 28 riding up the slope 36 of the cam A affixed to the bed 10 raises, through the agency of the arm 27, the leg 21 to tilt the cutter frame about the pivots 22, 23 for severing the stock, the cutter moving back from the stock as roller 28 moves down the slope 37 of the cam. As the cam B clears the arm 58 the valve lever 55 returns to its normal position thereby releasing the grippers 48. During the latter portion of this forward stroke of the carriage the trip lever R strikes the arm 54 of the control valve Y so cutting off the forward air supply to the cylinder 5 and allowing air to pass to the opposite end of the cylinder for the reverse stroke, and thus also giving a cushioning effect for the remainder of the forward stroke. This cushioning effect being overcome the carriage reverses direction, and towards the latter portion of the reverse movement the trip lever F strikes the arm 54 thus once again admitting air to the cylinder 5 for the forward stroke, and again producing a cushioning effect. The latch 64 engages an arm 63 on the carriage at the end of the return stroke, so retaining the carriage in readiness for the next forward stroke and under load due to the cylinder 5 being under full pressure. The cylinder 5 is pivoted to the base at 59, whilst the cam A can be adjusted with respect to the roller 28 and the trip lever F can be moved relative to the trip lever R.
