Abstract: 808,597. Pneumatic springs. GENERAL MOTORS CORPORATION. March 5, 1957 [March 30, 1956; April 2, 1956], No. 7255/57. Class 108(3) A vehicle air spring for interposition between sprung and unsprung portions of a vehicle (not shown) comprises a reservoir member 112 connected to a piston member 116 by a flexible. diaphragm 113 which is maintained in sealing engagement with one of the members 112, 116, by pressure of air in the member 112. As shown in Fig. 1, the outer end of the diaphragm 113 has bead 9 reinforced at 132 and urged by air pressure into engagement with a recess formed by the periphery of the member 112 and a flange 118 crimped thereto. A bead at the inner end of the diaphragm reinforced at 134 has snap engagement with the open end of the member 116. A cup-shaped element 117 is bonded to the bead. A con nection 114 leads to an engine-driven air compressor. Compression is limited by engagement of a flange 130 on the member 116 with th member 113 as shown in dotdash lines at A. In a modification (Fig. 2, not shown), the upper end of the member 116 is closed, and the cup shaped element 117 is replaced by a flanged disc bonded to the inner bead of the member 113 and secured by nut and bolt connection to the member 116. In the construction shown in Fig. 3, the reservoir member 12 is in two parts joined by bolts 18, and the space within is divided by a cup shaped partition member 40 into a main working chamber 15 and an outer expansion chamber 52 from which a pipe 14 leads to an enginedriven air compressor. A spring load flap valve 34 lifts, on compression of the piston 10, to permit air to flow through an aperture 50 in the member 40. On rebound, the valve 34 closes and air is limited to flow through a smaller aperture 36 in the valve. The periphery of the partition member 40 bears on the bead at the outer end of the flexible diaphragm 13, the pressure applied to which is thus the pressure in the chamber 52. The bead 54 at the inner end of the flexible diaphragm 13 is maintained by air pressure in engagement with a recess 62 of the piston.

As shown in Fig. 1, a pile fabric 30 passes from a roll 22 over an idler roller 23 and through the channel 3 in which it is crumpled transversely to form a narrow strand 25 which enters a carriage 6 in which it is guided by plates 27 between smooth or structured-surface drive rollers 4, 5. The carriage 6 runs on rolls 7 and is reciprocated periodically on horizontal rails 8 by a crank-drive. The rollers 4, 5 drive the strand 25 faster than it is drawn off by the rollers 13, 14 to crumple it longitudinally. The crumpled structure is maintained by imprisoning the strand 25 at the rollers 13, 14 between back cloths 20, 21 fed from rolls 18, 19. The three layer assembly 25, 20, 21 is wound on a member 24 driven so that the cloths 20, 21 remain stretched. Subsequently, the member 24 is removed and steamed to consolidate the fabric in the crumpled structure and leave a pattern thereon. In modifications (not shown), only one back cloth is provided or, if the fabric is made of thermoplastic material, the fabric is heated in the channel 3 and crumpled whilst in a heated condition so that the crumpled structure becomes fixed as the fabric cools. In another modification (not shown), a twisting device is mounted between the channel 3 and the rollers 4, 5 to produce further crumpling folds whose patterning overlies the longitudinal and transverse crumpling.

Abstract: 819,581. Thermally-actuated valves. LUWA A.G. March 12, 1956 [March 14, 1955], No. 7680/56. Class 135. A valve for regulating the flow of liquid heat transfer medium e.g. to a heat exchanger for heating and cooling, has a valve closure member 7 axially displaceable by a thermal element 35, 41 located outside the valve casing, and a valve seat body 2, 3 carrying opposed seats 10, 11 for the valve member and displaceable along the same axis by a thermal element 22 located in an uncontrolled by-pass 19, 21 for the heat transfer medium. When the element 22 is acted upon by a high-temperature heat transfer medium it expands and lifts the valve body against a stop 6 and spring 32 so that' the medium passes to the outlet 18 via casing channel 16, body passage 29 and seat 10. With increase or decrease in room temperature, the elements 35, 41 respectively closes or opens the valve 7 with respect to seat 10. When a cooling heat transfer medium is used the element 22 contracts and the body is lowered to abut a stop 5 so that the cooling medium passes to the outlet via casing passage 17, body passage 31 and seat 11. On room temperature increasing or decreasing, the element 35, 41 opens or closes the valve 7. with respect to the seat 11. The valve 7 may be adjusted or manually actuated by, a screw 45 moving a plunger 38 into the liquid of the thermal element 35, 41. In two other, embodiments the space 36 is thermally insulated from the rest of the valve casing to prevent the temperature of the heat transfer medium from affecting the thermal element 35, 41.

Abstract: 795,021. Electric tests; determining physical qualities and dimensions. ENGINEERING RESEARCH CORPORATION, Ltd. March 13, 1956 [March 23, 1955], No. 7825/56. Class 37. A condenser for use in liquid quantity gauges comprises two concentric tubular members of non-conducting material, e.g. resin-impregnated glass fibres, one of which has two mutually insulated electrode surface portions which form with the electrode surface of the other tubular member two condenser sections with independent zones of dielectric medium, the tubular members being separated by a spacer element located wholly within one dielectric zone, and terminated at each end by a perforated cap. In Fig. 1 the external surface of inner member 12 holds two helical conductive coatings which form the active electrode 18 and the ground electrode 20. The conductively coated inner surface of outer member 10 forms the outer electrode 16. A helical spacer element 24 of e.g. epoxy resin is located between the ground electrode 20 and the outer electrode 16, to either or both of which it may be cemented, the conductive coating being partially removed or masked to improve bonding. Threaded conductive element 26 (Fig. 3) passes through and secures together the outer member 10 a circular boss 29 in spacer element 24 and the inner member 12, and forms a terminal for ground electrode 20 to which it is connected through a retaining element 32 and a connection 36. Elements 38 and 48 (Fig. 1) provide terminals for active electrode 18 and outer electrode 16 respectively. Figs. 5 and 6 (not shown) depict profiling of electrodes 18, 20 to provide linear output when used in a non-linear container. In a rebalancing bridge circuit the outer electrode 16 may be connected to one end of the bridge transformer, the active electrode 18 to the input of the amplifier, and the ground electrode 20 to an intermediate point on the transformer. Moisture which fails to drain away collects on spacer element 24 and does not distort the capacity of the active condenser section.

Title: Improvements in and relating to coin-freed prepayment mechanisms
IPC: G07F15/02
Filed: 1934-03-12
Abstract: 433,968. Prepayment mechanism for meters. BRITISH ELECTRIC METERS, Ltd., BENTLEY, F., and BROWN, R. T., Morden Road, Mitcham, Surrey. March 12, 1934, No. 7834. [Class 27] In prepayment meter mechanism in order to prevent the quantity wheel from moving by inertia or by slipping through a larger or smaller angle than that corresponding to the amount of prepayment, it is automatically locked in correct position concurrently with the discharge of the coin from the rotary coin receiver and before it is disengaged from the receiver. The quantity-wheel 2, Fig. 1, is carried by a spindle 4 having wheels 5 gearing with the usual measuring-out mechanism, and having a forward extension 9 provided with a groove 10. The spindle 4 is capable of slight longitudinal movement and is normally held by a spring 6 with peripheral ratchet teeth on the wheel 2 in engagement with a fixed locking stop 8. When a coin is inserted into a coin receiver rotatable in a coin drum 3 it enters a pocket formed by plates 16 disposed between end plates 12, 13 and depresses a pivoted lever 17. Claws 20 on this lever engage the groove 10 and move the wheel 2 out of engagement with the stop 8 and into engagement with a tooth 22 mounted on the rear plate 12, the wheel engaging the tooth 22 before being released from the stop 8. A spring 21 connects the lever 17 and tooth 22 and allows a slight movement of the tooth to enable it to position itself in engaging relation with the wheel 2. After rotation of the receiver, a stop 24 thereon meets a fixed stop 25 and the coin is discharged by the lever 17 through a slot 23 in the drum 3. The wheel 2 is immediately moved back into engagement with the locking stop 8 and is released from the tooth 22 after engaging the stop. Specification 342,008 is referred to.

Filed: 1946-03-14
Abstract: 607,848. Gramophone pick-ups. BAKER, D. J. March 14, 1946, No. 7991. Convention date, March 12, 1945. [Class 40 (iv)] A recording or reproducing head comprises a horizontal magnetic reed clamped at one end and with its other end free to oscillate in a horizontal plane between the poles of a magnet and carrying the stylus substantially at right angles to its axis. The reed has a natural frequency in the upper audio-frequency range. The reed 8, Figs. 1, 2, is a flat strip of magnetic material, rigidly secured at one end to a metal block 6, set in a vertical plane and surrounded by a coil 12 which may be wound directly on it or spaced by means of a former. The free end has the stylus 9 permanently secured to it and vibrates in the vertical air-gap between the poles of a magnet 5, Fig. 3. The moulded plastic body of the pick-up provides emplacements for the block 6 and magnet 5 and also has two pillars 14 between the reed and which there is damping material 13. The reed may be laminated or may be constructed so as to be relatively rigid over the greater part of its length, but flexible at the extreme end. This assists in obtaining a high resonance frequency which is preferably of the order of 10,000 c.p.s. A rubber washer 10 may surround the stylus to exclude dust. In another construction, the reed is made short in length and the block 6 is set correspondingly close to the magnet, Fig. 6 (not shown). The Specification also describes a modification in which a second coil, of similar magnetic characteristics to that on the reed, is mounted adjacent to the latter and connected in opposition to it, so as to overcome the effects of external magnetic fields.
