Abstract: 1305606 Refrigerating PHILIPS GLOEILAMPENFABRIEKEN NV 3 March 1970  [6 March 1969] 10143/70 Heading F4H A cold gas refrigerator comprises a first compression space 7 of variable volume in a cylinder 1 which communicates serially with expansion spaces 11, 15 of variable volume via regenerators 9, 13 and freezers 10, 14 respectively. The working medium after throttling in a valve 19 and cooling an object or space 20 is recirculated back to the refrigerator via the low pressure side of a heat exchanger 18 for further compression in a second compression space 28 of variable volume formed in the bore 21 of a displacer 3. A hollow piston-like body 22 is fixed to the upper wall of the expansion space 15 and the common axis of the bore 21 and body 22 coincides or is parallel to the axis of the displacer. The interior of the body 22 communicates with a duct leading. from the throttle valve 19 and through a valve 23 to the compression space 28 which has an outlet incorporating a valve 27 arranged to open when the pressure in the space 28 exceeds the minimum pressure occurring in the refrigerator to allow the working medium to pass via a buffer space 29 to the intermediate expansion space 11 through a non-return valve 31. In a modification, a plurality of intermediate expansion spaces communicating in series through regenerators of decreasing temperatures are provided, and a similar number of further compression spaces are formed in a stepped bore of the displacer, which spaces are serially connected through valved ducts, at least one of these ducts being in heat exchange relationship with an intermediate expansion space.

Class 61 [Also in Group XXIV] A vice screw spindle 7 has two coaxial threads 6, 14 of different pitch arranged in series on the same shaft and engaging in different nut members 5, 9 the arrangement being such that normally the quick pitch thread 6 is used, the slow pitch thread 14 being prevented from co-operating with its nut 9, but that the slow pitch thread 14 is adapted to be put into operation when great longitudinal force is required, the threads 6 at the same time be-. ing prevented from slipping back. As shown the base 1 of the vice carries the fixed jaw 2 and the nut 5. The movable jaw 4 is carried by the sliding member 3 which is recessed at 8 to receive the cap nut 9. The nut 9 has an annular shoulder 10 which bears against the end of the member 3, the nut being rotable by a wrench or handle 13. The spindle is prevented from turning in the nut 9 by two spring loaded balls 16 provided in transverse bores 15 in the nut and engageable in recesses 17 in the spindle. The gradient of the quick pitch screw is sufficiently low to ensure self locking. On rotation of the handle 13 the spindle 7 rotates jointly with the nut 9 until resistance is encountered the resistance increasing until a point is reached at which the spring loaded balls are forced out of the recesses 17 whereupon the slow pitch threads 14 come into action.

Title: Means for preventing the aeration of oil in oil circulating means
IPC: F16N7/40
Filed: 1941-08-22
Abstract: 552,255. Aeration preventing in liquid pumps. LE CLAIR, C. C. S., and TELCALEMIT, Ltd. Aug. 22, 1941, No. 10705. [Class 102 (i)] In a liquid circulating system in which a pump withdraws liquid from a container, aeration of the liquid circulated by the pump is prevented by a level detecting means which permits or stops the flow of liquid from a supply source to the pump when the level of the liquid in the container is low or high, respectively, and the flow of liquid from the container to the pump is stopped when the pump is receiving liquid from the supply source. In the form shown, oil from an engine sump 1 is drawn by a scavenge pump 2 through a suction pipe 3 with a spring-pressed bias valve 5, and is delivered by a discharge pipe 4 to a storage tank from which it is returned to the engine by a pressure pump. An auxiliary pump 8 is connected to the sump 1 by a smaller suction pipe 7 arranged with its end above the end of pipe 3, and the discharge pipe 9 from the pump 8 is connected to the pressure end of a cylinder 10 which is connected by a flow-restricting orifice 11 and a return pipe 9a to the sump 1. The cylinder 10 contains a spring 23 and a piston valve 12 having a piston part 13 which acts against a stop 24, and valve parts 14, 14a separated by a recess 15 which co-operates with inlet and outlet ports 16, 17 connected by pipes 18, 19, respectively, to the storage tank and to the suction pipe 3. The parts 13, 14 are separated by a space 21 which is connected by a port 22 and a small leakage bleed-off pipe 20 to the sump 1. When the level of the oil in the sump 1 is above the end of the pipe 7, the auxiliary pump 8 circulates oil, and pressure is built up in the end of cylinder 10, due to the resistance of the orifice 11, to force the valve 12 into the position shown. The ports 16, 17 are closed by the valve part 14 and oil cannot flow from the storage tank to the suction pipe 3. The demand of the scavenge pump being greater than the supply, the oil level in the sump falls until it is below the end of pipe 7. The auxiliary pump 8 then circulates air, the flow of which is not resisted by the orifice 11 so that the spring 23 forces the valve 12 against the stop 24. Oil then passes from the storage tank to the suction pipe 3, flow of oil from the sump 1 being prevented by the bias valve 5, so that the level of the oil in the sump again rises. By this means the oil level in the sump is maintained approximately at the level of the end of the pipe 7 and flow of air through the scavenge pump 2 is prevented. In a modification, the return pipe 9a and the orifice 11 are formed in the valve 12 itself, the bleed-off pipe 20 is enlarged, and the stop 24 is placed eccentrically or provided with an internal port. Alternatively, the piston valve may be replaced by a bellows or diaphragm operated valve.

Abstract: 351,595. Weft-feeler arrangements. MASCHINENFABRIK RœTI VORM. C. HONEGGER, R³ti, Zurich, Switzerland. April 4, 1930, No. 10720. Convention date, April 13, 1929. [Class 142 (iii).] A weft-feeler device for indicating exhaustion of weft in the shuttle and for initiating weft replenishment, comprises a feeler wire 1 formed with a triangular contacting portion A, surrounded by a helical spring 14, and a circular part B, the latter being slidably accommodated within a box 4 on the breast beam and yieldingly held against an abutment 8 thereon by means of a spring 7. The feeler wire 1 is also formed with a bent portion 2 located adjacent to a loosely-mounted pin 9, which on being displaced engages a spring-mounted member 11 and makes an operative connection between a reciprocating member 13 on the lay and a member 12 associated with the cop changing mechanism. During the normal working of the loom and while there is sufficient weft on the cop, the feeler receives a longitudinal movement in the box 4 with the advance and return of the lay; but upon weft exhaustion, the feeler receives two distinct movements, the weft replenishing mechanism being operated only after completion of the second movement. At the first step, the feeler is deflected laterally, by the head coming in contact with the denuded bobbin, to bring the bent portion 2 just into contact with the pin 9 and the subsequent advance of the lay causes the feeler to be moved forward and to displace the pin 9 which in turn. pushes the member 11 between the members 12, 13. Specification 261,299, [Class 142 (iii), Looms, Weft supplying &c. in], is referred to.

Abstract: 641,123. Railway-vehicle bogies. WHYMAN, F., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 21, 1948, No. 11000. [Class 103(vi)] In an electrically-driven double-bogie locomotive the ends of adjacent bogies 10, 11 are coupled together by a vertical link 12 to prevent or limit their relative vertical movement and thus equalize the wheel loads, while permitting relative pivotal movement of the bogies about their vertical axis. In the arrangement shown in Fig. 1 the link 12 is of fixed length, and the coupling pins 13, 15 are journalled in bushes of the kind known under the Registered Trade Mark " Silentbloc " to allow the relative pivotal movement of the bogies. Alternatively, the link may embody universal or ball-and-socket joints for this purpose. In the embodiment shown in Fig. 3 the link is formed of two telescopic portions 18, 19 with a limited degree of elongation, and springs may be provided to cushion the movements of the two portions. Fig. 5 shows a further embodiment in which the upper end of the link is connected to a pivoted bracket 21, the angular movement of which is limited by fixed or spring stops 23.
