Patent GB-988969-A (GB)
Title: Improvements relating to label, ticket or like cutting and collecting cash registers
IPC: B41J1/00
Filed: 1963-04-26
Abstract: 988,969. Locks. C. & A. BRENNINKMEYER G.m.b.H. April 26, 1963 [April 28, 1962], No. 16574/63. Addition to 922,776. Heading E2A. [Also in Division G4] A cash register includes a cutting device which detaches a stub portion of an inserted voucher and stacks it in an inserted receptacle in order to keep a record. As shown a receptacle 5 with a lid 77 and a locking flap 75 closed is inserted in a chamber 3 in the register where it is retained in place by a spring pawl (45 in Fig. 1 not shown). A key 83 retained in the machine can then be inserted in a lock 84 in the receptacle and the flap 75 opened so that the receptacle can be moved forward to the operating position in a condition to be filled. The key ensures that the receptacle cannot be removed from the machine until it has been locked and the key withdrawn. When the receptacle has been withdrawn from the machine a collar 93 is positioned in a bore 105 and cannot be rotated. The receptacle is inserted in its closed condition and the key and collar are forced inwardly against the action of a spring 106 until the key enters the lock 84. The collar 93 is now in a bore 119 and thus the key can be rotated to open the receptacle. When the receptacle is open the collar 93 has rotated so that it can be slid along the slot 94<SP>1</SP> as the receptacle is moved to the operating position.

Title: Improvements in Apparatus for Measuring and Sorting Rods or Wires.
IPC: G01B3/24
Filed: 1916-11-21
Abstract: 109,163. British Thomson - Houston Co., (General Electric Co.). Nov. 21, 1916. Index h a n d s and pointers.-In a gauging- apparatus for indicating the diameters of rods and tubes at different points, a pair of index hands 3, actuated by separate gauges, moves over a single scale. The hands are formed as tridents, so that their outer prongs 13 may indicate the maximum passable taper of the rod &c. Each scale graduation represents a diameter which equals <10>W2 of the preceding one, and by means of a suitable formation of cams controlling the index hands all the widths between the graduations are reduced to equal size.

Normal, elevated or reduced pressure may be used, the initial reaction taking place at room temperature and the cyclization stage at elevated temperature. Phosgene is used to treat in examples (1) glycollic acid; (2) thioglycollic acid; (3) lactic acid; (4) mandelic acid; (5) lithium lactate in dioxane solution; the solvent is evaporated under reduced pressure and the resulting oil heated to produce the corresponding anhydrocarboxy-a -hydroxy- or a -mercapto-carboxylic acid.  In 1) an intermediate product is believed to be formed thus: ClCOCl+ HOCH2COOH--->ClCOOCH2COOH.

A radial cord carcass pneumatic tyre comprises a breaker including cross-laid layers 6 of wire cables or cords forming an angle of less than 20 degrees to the mid-plane laid around two or more layers 7 which are not cross-laid and the wire cables or cords of which extend at a substantially equal angle to mid-plane of between 60 degrees and 90 degrees. The axial width of the layers 7 may be between 105% and 85% of that of the tread rolling surface, but preferably the layers 7 subtend at the "centre" of a tyre radial cross-section an angle greater than that subtended by the tread rolling surface. ("Centre" is the intersection between the line of maximum axial width and the mid-plane.) The edges of plies 6 and 7 may be covered by rubber strips 10 and cushion layers 9, the latter having a smaller hysteresis than the tread rubber to reduce heating. The layers 7 are preferably metal cords calendered in rubber of small hysteresis, e.g. 65-70 degrees Shore A, the cords of layers 6 being in rubber of 80 degrees Shore A hardness. The cords of layers 6 may be formed of thirty-eight wires each of 0À15mm. diameter, and those of layers 7 of seven strands of seven wires each of 0À17mm. diameter.

Abstract: 1,268,111. Linkwork; toothed gearing. MICROMEDIC SYSTEMS Inc. 1 April, 1969 [2 April, 1968; 19 Aug., 1968], No. 17068/69. Headings F2K and F2Q. [Also in Division F1] A pump 1a has a reciprocating piston 102 driven by a motor 4 through intermittent toothed-gearing, a variable-throw crank-mechanism 320 and a lever 339 pivoted at 340. The mechanism 320 has rotary members 332, 328 with slots 323, 329 housing an axially-movable spring-loaded blade 324 attached to a micrometer screw 601 and engaging with elements 334, 335 on an eccentric ball-bearing 333, which is coupled to the lever 339 by a rod 336 and ball 337: Rotation of the screw shifts the blade axially to change the eccentricity of the bearing. A counter 701 is coupled to the screw by a chain 703. The toothed gearing includes a pinion 14 having a frictional torque-limiting device, Fig. 8 (not shown), and meshing with a gear-wheel 301 having recesses 307, 307<SP>1</SP> aligned with a gear-wheel 306 coupled to the mechanism 320, the pinion being driven by the motor through speed-reducing gear 5. The recesses result in intermittent rotation of the wheel 306, arms 310 and pins 311, 311<SP>1</SP> being provided to turn said wheel into mesh with portions 308 between the recesses. The pinion also drives a second pump through gear-wheels that are identical to the gear-wheels 301, 306. In a second embodiment, Figs. 12 and 15, the variable-throw crank-mechanism includes a yoke 370 connected to a " slide " 368 in a pair of slideways 369 within a fixed sleeve 364, the slide engaging slidingly with a crank-pin 357 coupled pivotally to an axially-movable head 363 and a pin 359 in blocks that can slide axially in grooves 360 within a rotary member 356, which is driven by the motor through gearing similar to that shown in Figs. 1 and 2. Rotation of the member 356 makes the pin 357 revolve along an asymmetric conical-path (the pin being horizontal as shown only when at its uppermost position); and thus by shifting the head 363 axially by means of a micrometer screw 378 the stroke of the piston 135 is varied without affecting the top-dead-centre position. Arms 353, 355 effect intermittent rotation of a valve member 231.

Class 135 The thermostatically controlled mixing valve, as shown, comprises a two-part hollow casting 11,12, clamped together at 48, e.g. by tie bolts and yokes 54, 56, each part having an inlet 13, 14 for cold and hot water respectively leading past check valves 64, 62, over the ends of a spring-loaded hollow cylindrical valve 37 and through a mixing chamber 16 containing a thermal element 20 for actuating the valve, to passages 21. The flow of mixed fluid from the passages 21, through a port 24 in the end wall of the casing, a chamber 25, passage 27 and outlet 42 containing an apertured constant flow producing rubber disc 41, is controlled by a fluid-pressure operated rubber diaphragm valve 22 containing an orifice 87 and a port in a central metal insert 83 controlled by a solenoid actuated valve 84. A similar valve 33 in the lower casing part controls the flow of hot water alone via passage 30, bore 35, and byepass 36 to the outlet. Thus the outlet temperature corresponds to that of the hot, mixed or a combination of hot and mixed water. Each check valve comprises a cup 60 having a flexible disc 62 retained over the perforated bottom of the cup by ribs 61 extending through certain of the perforations.
