Patent GB-724043-A (GB)
Abstract: 724,043. Calculating-apparatus; transfer mechanism. AKTIEBOLAGET ATVIDABERG-FACIT. Oct. 10, 1952 [Oct. 11, 1951], No. 25479/52. Class 106 (1). Transfer mechanism for a cam-disc and pinwheel calculating machine in which subtraction is performed by shifting the rotor laterally relatively to the totalizer so as to render the operated pins ineffective and the unoperated pins effective, comprises a single transfer pin for each wheel which co-operates with the same number wheel or intermediate pinion in both addition and subtraction. At transfer, a tooth 25a on the intermediate pinion 25 rocks a transfer lever 30 which is held in its operated position by a ball detent 32. A cam surface on the lever is thus placed in the path of the transfer pin 11 of the next higher order which is rocked laterally thereby so as to engage and advance by one step the pinion 25 with which co-operates a spring detent 28. The transfer pins 11 are helically arranged on the rotor to effect transfers in sequence and each is pivoted in its wheel 5 and acted upon by a spring 12 so that, in the vicinity of the pinion 25, it is held against the transfer lever 30, if this has been operated, or against an offset guide portion 18a of the corresponding stabilizer frame 18. Thus whether the rotor is in the addition position, Fig. 4, or subtraction position, Fig. 3, the transfer pin is guided for proper co-operation with the pinion 25. Alternatively, instead of employing the guide portions 18a, each transfer pin may be formed as a bell-crank lever, the inner end of which engages a ball located in a guide in the rotor tube 4 and running in a groove in the driving shaft 2. Operated transfer levers 30 are restored by a spline 35 in a shaft 34. The digit pins 8 are formed as levers pivoted in the wheels 5, one arm of each engaging the groove 13a in the differentially-settable cam disc 13 which is held in its set position relative to the pin-wheel by a ball detent 14. The units wheel has ten pins and the other wheels nine. The several cam discs are also locked by a transverse locking bar 15. The pin-wheels and cam discs are assembled on the rotor tube 4 and clamped together by a nut 7 acting on an end disc 6 by which the rotor is shifted axially from denomination to denomination or to the intermediate (subtraction) positions.

Abstract: 780,183. Metal rectifier assemblies. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., WALKER, A. H. B., BURCH, D. E., and LOCKETT, L. J. Feb. 12, 1954 [March 31, 1953; May 29, 1953], Nos. 8906/53 and 14972/53. Class 37. A rectifier assembly comprises a block of insulating material 4 (Fig. 2), e.g. that sold under the Registered Trade Mark " Bakelite," with a plurality of holes 3 extending between two parallel faces thereof containing stacks of rectifier elements, e.g. of selenium or copper oxide type. A flexible sheet of insulating material (Fig. 6) with metallic connections 10 formed on one face, e.g. by spraying, is folded to form first, second and third panels 5, 7, 12 respectively abutting said parallel faces and another face of the block so that the metallic connections contact and interconnect the stacks as desired. One of the connections extends from the first to the third 12 or to a fourth panel on a fourth face of the block. A sheet-metal container abuts the flexible sheet and presses it into good thermal contact with at least one end of the stacks. Coil-springs may be placed in each hole on top of the stacks to form electrical connections between the elements and metallic connections on panel 7 and to press the elements into good electrical contact with the connections on panel 5. External connections to the unit may be made via spade connectors formed with arms which extend through the slits 9 in the block. In a further embodiment (Figs. 8 and 9) the case is formed by channel-section member 14 the side limbs of which are extended to form the ends of the case and then formed into flanges 27 clamped together by eyelets 28. An insulating sheet extends around four sides of the block. External connections are made to sprayed on connections on the fold 5b by means of metal eyelets 18, with tags 19, which pass through holes in stiffening cardboard sheet 17 and the sprayedon connections and clamp washers 20, clearance holes 16 being cut around the eyelets in the channel member. Connections may be made in similar fashion to sprayed-on connections on fold 5d through insulating or metal stiffening sheet 23. Metal spacers 15, 22 between the end elements of each stack and the sprayed-on connections prevent short-circuiting of the thin semi-conductor layer by the insulating sheet flexing around the edges of the element under pressure of spring 21. The fourth side 5d of the sheet which carries connections between the ends of stacks adjacent side 5c may not be required in which case the sheet 23 is not used and the block 4 is held in place without folding over the edges of the channel member (Fig. 12, not shown). Where the metal case is to be used as one terminal of the arrangement the spring is positioned at one end of the stack and is formed with a pip which contacts the case through a hole in the insulating sheet. Alternatively, eyelets are fixed to the sheet adjacent the appropriate spring or springs to form the connection. The metal casing may be formed with tabs, instead of flanges, which are folded over and screwed to the insulated block. The screws may serve at the same time to fix the assembly to a mounting.

Title: Apparatus for removing entrapped gas and separating out particles from fluid
IPC: F16N39/00
Filed: 1979-10-24
Abstract: In an apparatus (10) for removing entrapped gas and selectively removing and detecting particles above a predetermined mass in an oil lubrication system, the oil enters tangentially at the top of an outer cylinder (12) and is caused to cyclonically work its way down to the bottom of the cylinder. The oil is then forced to reverse its flow and travel up along and out through an inner cylinder (44). The centrifugal force fields created by such flow first cause entrapped gas to coalesce in the centre of the flow pattern so that it can be vented from the system via a tube (24). It also causes heavier particles, which are used by the apparatus to detect impending failure of components of the system, to be thrown out of the flow pattern into a detection chamber (28) which communicates at (32) with the interior of the outer cylinder while lighter particles remain suspended in the oil. A magnetic sensor (30) is provided at the entrance to the chamber to signal to the operator of the system the presence of the heavier particles which are trapped in the chamber for subsequent removal from the system. <IMAGE>
