Patent GB-395981-A (GB)
Abstract: 395,981. Calculating-apparatus. ASTRAWERKE AKT.-GES., Chemnitz, Germany. Feb. 15, 1933, No. 4676. Convention date, Jan. 5. [Class 106 (i).] A single key-bank, independently operated machine with a laterally movable stop field is adapted to deal with British currency as well as with numbers in the decimal notation. The totalizer comprises geared pinions on parallel shafts, one or other pinion being movable into engagement with the actuating racks for addition and subtraction respectively. The ordinary actuating members carrying the racks are provided with means under the control of the " 10 " and " 11 " keys for adjusting the movement of the member to effect the operation of the non-decimal units of the totalizer. In the machine shown in Fig. 1, two totalizers are provided with interconnected pinions 1, 2, 1<1>, 21, on parallel shaft 3, 4, 31, 4<1>, and are adapted to be moved into engagement with racks 5, 51 mounted on actuating members 7. The extent of movement of each of the members 7 is determined by a projection 20 engaging a projected stop 19 in a carriage 21, the stops being set by depression of keys 22 in a known manner. In order to compute in British currency units the pence and farthings pinions have twelve and eight teeth respectively. As these wheels are mounted on the shafts 3, 4, &c. with the ten toothed wheels their pitch differs and a transmission device arranged on the actuators is provided to adjust the movement. In the pence denomination the actuating member 7a, Figs. 2 and 3, is provided at its lower edge with a rack 29 engaging a tentoothed pinion 25 to which is integrally connected a twelve-toothed pinion 27 engaging teeth on a slidable member 28 guided on bars 10, 11 that carry the actuating members. The slide 28 is provided with movable abutment noses 30, 31 which normally lie in the path of the stop elements 19. The noses 30, 31 are under the control of levers 32, 39 co-operating with the 10-pence key and the 11-pence key respectively. When the " 10 " key is depressed the nose 30 is lowered out of the operative position with respect to the end stop 9a. On depression of the " 11 key the nose 31 is lowered and through the co-operating projection 38 on the nose 30 it takes this latter with it permitting the slide 28 an additional movement before its arrest by the stop 9a. On the return movement of the carriage 21 an arm depending therefrom rocks a lever 35, the other end 34 of which restores the depressed noses at the end of an operation. In the farthings denomination the fraction pinions 41, 42, Fig. 4, are of the same pitch as the decimal wheels and consequently are connected by transmission gears 43, 44, the adjustment of the actuators being effected by the " 2," " 4 " and " 6 " stop elements 19.

IPC: G05D16/20
Filed: 1961-11-07
Abstract: 968,896. Valves. IAN NICKOLS Ltd. Feb. 6, 1963 [Nov. 7, 1961], No. 39801/61. Heading F2V. [Also in Division F1] A fluid pressure operated valve comprises a cylindrical body 1 having first and second main chambers 20, 30 separated from first and second subsidiary chambers 22, 32 by pressure sensitive members 23, 33, and passages 41, 51 interconnecting the second main chamber 30 to the first subsidiary chamber 22 and the first main chamber 20 to the second subsidiary chamber 32, and a common fluid source 60 feeding through passages 40, 50 and calibrated orifices 25, 35, closable by the members 23, 33, into the first and second subsidiary chambers 22, 32, and first and second main chamber bleed vents 28, 38 arranged to be alternately opened and closed by a relay 54. The first main chamber 20 has a connection 26 and the second main chamber 30 has a connection 36 to one or both of which pressure operated devices are connected. In the position shown fluid flowing from the source 60 is prevented by the diaphragm of the pressure-sensitive device 23 from entering the first subsidiary chamber 22 but passes to the passage 50 and the orifice 35 into the second subsidiary chamber 32 and thereby flows to the first connection 26. When the electromagnetic relay 54 is energized to thereby attract an armature -55 against the action of a spring 56, a seal 52 closes the second bleed vent 38 and simultaneously opens the first bleed vent 28. The fluid in the first main chamber 20 and hence the fluid passing to the second subsidiary chamber 32 is vented through the bleed 28 and allows the pressure-sensitive member 23 to open the orifice 25 so that pressure builds up in the second main chamber 30 and connection 36 to close the orifice 35 and thereby terminate the supply of fluid to the first main chamber 20. If the relay 54 is de-energized the pressure again builds up in the first main chamber 20. The pressure-sensitive members may be piston or poppet valves or diaphragms, as shown.

Abstract: 936,031. Supporting X - ray equipment. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1959, No. 40419/59. Class 98 (1). [Also in Group XXX] A load such as an X-ray apparatus and auxiliary equipment is supported from a suspension point 17 by a cable passing over overhead rollers to a counterweight 20, the force exerted by the load at said suspension point being counterbalanced by one or mora springs, so that a limited degree of upward or downward movement of the load is possible without any displacement of the counterweight. In Fig. 1 the load comprises an X-ray tube 6 and carriage 7, connected by an arm 4 with an intensifier 1 and camera 2. The load is suspended by a yoke 16 from a floating roller 17. The roller 17 is itself suspended by a cable 18, attached at one end to a fixed point 19, and at the other end, after passing over various support rollers 23, 24, 22, 21, to a counterweight 20. Rollers 23, 24 are fixed to a lever 29 pivoted at 30 to a carriage 25 which travels horizontally along a guide 26. The lever can pivot downwards under the action of the weight of the apparatus, as shown in dotted lines. This movement is counterbalanced by a torsion spring 31, one end of which is attached to a lug 32 on the lever and the other end to a lug 33 on the carriage 25. Thus the pivoting action of the spring-loaded lever 29 allows a certain amount of up-and-down movement of the load without having to displace the counterweight 20. In the modification of Fig. 2, the load is attached to a cross-bar 37 which can slide up and down on rods 35, 36 fixed to a yoke 38. Downward movement of the load acts against springs 41, 42, tensioning arms 39, 40 attached to the cross-bar 37.
