IPC: F02P17/00
Filed: 1933-06-22
Abstract: 420,242. Testing and indicating ignition. DICKER, S. G. S., 20, Holborn, London- (Fernandez, J. J.; 618, Cokesbury Avenue, and Gibson, M. S.; 3300, Woodland Avenue, both in Baltimore, U.S.A.) June 22, 1933, No. 17859. [Class 7 (iv)] Spark-gaps in shunt with the sparking- plugs are formed between normally stationary but adjustable terminals 11 and cam - like terminals 15 mounted on a shaft 14 driven from an electric motor 18 through reducing gear 19. The circuit from the terminals 11 to earth is completed through a fixed contact 25 and arm 24. This latter may be rotated to engage a second contact 21 for short-circuiting the plugs as well as the gaps between the terminals 11, 15. The stems of the contacts 11 are threaded into bushes in an insulating panel and carry pointers which work over scales indicating the sizes of the spark gaps. Further gaps are formed between the contacts 21 and the earthed spindles of the switch arms 24. The high-tension distributer is connected by a lead 60 to a brush making contact with a star 62 rotating on the shaft 14. An angularly adjustable terminal 63 earthed by lead 65 to the bar 34 affords a gap of adjustable size by which the efficiency of the distributer may be assessed. For testing the primary circuit including the interrupter and condenser, a branched circuit may be used consisting of a lead 50, and two-way switch 56 leading either to an electrical measuring instrument 58, or to a rheostat 52 and red lamp 54. A steady indication of the instrument 58 is to be looked for if the interrupter and the carburetter are working uniformly. A graduated segmental chart is associated with the rotary arm 51 of the rheostat, and by inserting varying resistances in shunt with the interrupter and condenser, percentage efficiencies may be observed from the chart. The spark gaps, scales, and other indicia are observable either directly or by reflection through sight openings in the overlying panel.

Abstract: 487,364. Handling removable load - containers. MOTOR TERMINALS, Inc. June 26, 1937, No. 17860. Convention date, June 29, 1936. [Class 78 (iv)] [Also in Group XXXII] In apparatus for transferring removable load - containers between a rail and road vehicle in which both vehicles are provided with channels engaged by skid rails on the container, the channels are constructed so that the skid rails contact with both base and side walls near their ends only. Figs. 3, 6 and 7 show one construction in which the channels on both vehicles A, C, Fig. 3, are fitted with internal projections 15 near each end forming the side contactpieces for the skid rails during transit. These projections taper off at each end and guide the skid rails of an oncoming container towards alignment with the channels ; engagement with the first pair permitting latitude in the alignment until the second pair is encountered. Engagement with the parallel portions 17 of two sets of projections secures exact alignment of the rails in the channels. Turn-up hinged brackets may be used to prevent the containers moving transversely of the rail vehicle while the latter is in transit. Drainage holes are provided in the bases of the channels on the rail vehicle. The projections are also tapered upwardly as shown at 18, Fig. 6, so that containers lowered on to the vehicle by a crane are guided into the channels. The containers for purposes of illustration, are shown provided with skids as described in Specification 487,376. In one construction, the under surface of the skid rails, including the curved ends 23, are provided with phosphor-bronze contact-plates 25, Fig. 7, at each end, which project below the general level of the base of the rail and form the contactpieces between the rails and the bases of the channels. Fig. 8 shows a modification in which steel castings 26 having upwardly-curved ends 23 also tapering inwards from the sides, are welded to the ends of the main skid rails and project below the level of the latter.

Abstract: 1,134,423. Pumping liquids. ASSOCIATED OCTEL CO. Ltd. April 27, 1967 [April 27, 1966], No. 18466/66. Heading F1R. In liquid transfer apparatus for transferring liquid from a first to a second tank a priming vessel is first connected to and filled with liquid from the first tank and subsequently liquid is drawn through the priming vessel and discharged into the second tank. In the first embodiment shown in Fig. 1 the priming vessel a is evacuated by an ejector p supplied with water by a pump r from a reservoir S so that liquid is drawn in from tank f. At a level determined by a float switch U the valves h, l, m, k are operated, pump r is stopped and the pump g is operated to draw liquid from tank f through the vessel a and discharge it to the tank i which may be vented back to tank f. When tank f has been emptied the pump r is started by float switch b so that vacuum is applied to pipes d, I while they are being disconnected. In a second embodiment Fig. 1a (not shown) the pump g is mounted within the vessel a. In a third embodiment Fig. 2 the pump 105 is mounted in the priming vessel 100 and by circulating residual liquid 104 through an ejector 111 liquid is drawn from a tank 103 into the vessel 100, air being discharged at 106. Subsequently valves are closed by switch 117 and the pump 105 pumps liquid from the tank 103 to the tank 109. In a further embodiment Fig. 3 (not shown) the arrangement is similar to that of Fig. 1 but the discharge pump is that described in Specification 1,094,818 and the apparatus is used to inject lead alkyl from a tank 19 into a gasoline line 31 in quantities measured by the pump which first empties the tank 19 into tank 32 and subsequently pumps from 32 into the line 31. Alternatively it may pump from tank 19 directly to the line 31.

Abstract: 408,222. Sound and like records. MILLER, J. A., 4627, 193rd Street, Flushing, New York, U.S.A. Sept. 26, 1932, No. 18521/33. Convention date, Sept. 30, 1931. Divided on 411,144. [Class 40 (ii).] A blank adapted to receive a record of sound or like vibrations, which record is suitable for optical reproduction, comprises a transparent film or other supporting base 1 of celluloid or the like and a recording layer 2 of transparent material, which is sufficiently soft to allow of its being cut into by a vertically oscillating stylus and has such thickness (viz. at least .012 mm.) that the stylus does not penetrate to the relatively hard base. The soft layer 2 may be of gelatine, wax, soap, or the like, and it may be initially coated with an opaque layer 3, e.g. of black ink, dye, graphite, or an exposed and developed photographic emulsion. By means of a V-shaped recording tool 4, a record is made by removal of parts of the layers 2, 3, and reproduction can be effected immediately after recording, by the action of transmitted light upon a photo-electric cell. The opaque layer may be reflective, so that reproduction can be brought about by means of reflected light. Instead of providing a coating 3 initially, the sound trace or its surroundings may, after recording, be suitably coated to produce the necessary optical contrast. The film may be formed with a longitudinal ridge 7, Fig. 2, on which the record may be made by means of a flat-edged chisel 8. Instead of a film, a disc or cylinder may be used as the record carrier.

Abstract: 666,862. Picking motions; checking shuttles in looms. MORRIS, H. N. July 13, 1948 [Dec. 11, 1947], No. 18750/48. Class 142(iii) A piston moved in a cylinder by fluid pressure, is carried by a hollow piston rod having ports through which the fluid in front of the piston is exhausted during picking. In an embodiment operated by compressed air, a cylinder 8 has an air inlet valve 13 opened against spring pressure by a member 19 on a rock shaft 17 moved by a cam-actuated push rod 20a. Air entering the cylinder moves the piston 11, piston rod 12, and picker 21, and air in front of this piston escapes through ports 22 and openings 21a in the picker face. The piston is checked by air compressed in the cylinder when the ports 22 in the piston rod pass out of the cylinder. The piston is returned by a shuttle entering the box. An exhaust valve, near the inlet valve 13, is open during the first part of the return stroke but then closes to provide an air cushion to check the piston at the end of its stroke. A one-way valve 23 enables air to enter the cylinder during the return stroke. The exhaust valve opens into a manifold. The initial movement of the picker releases a swell at the commencement of picking. The invention may be operated by other fluids under pressure.
