Filed: 1928-07-04
Abstract: 315,092. Carter, E. B. July 4, 1928. Beads, threading.-Concave-convex washers of the type used in making rubber heels are strung on wires with the convex side downward by a machine which is stated to be capable of stringing eyelets, grommets, or the like, particularly where a predetermined position of the articles is required. From the wires the articles may be fed into chutes for stacking for subsequent use. As shown, washers are contained in a hopper 64, Fig. 3, into which dips a rotating inclined table 11, having recesses 41, Figs. 4, 5, and 10 for the washers. The recesses are contained in inserts 32 in the table, and a washer is carried on or drops out according as a concave face is or is not presented. The table has a. series of the inserts arranged in radial rows, as shown, and also has concentric channels 40 corresponding to the position of the perforations in the washers, threading spring-pressed wires 50, Figs. 2, 10, and 12 being arranged to engage the guideways tangentially, as shown, and spear the washers. Figs. 4 and 5 show a washer in its recess as the table rotates, and Fig. 10 shows it after it has fallen and has been tilted by a round-nosed edge 45 of the recess until it engages a pocket 46. It is then in position for engagement by one of the threading wires 50. Fig. 12 shows the lower portion 50 of a wire with some washers thereon, a bulbous enlargement 62 serving as a stop for the first washer. The wire is mounted in a socket 56 pressed upwardly by a spring 59 and guided in its longitudinal movement by a pin 61 in a slot 60. Should a washer be imperforate or otherwise faulty, the wire is pushed downwardly against the action of the spring and the faulty washer drops below the wire.

Patent GB-531692-A (GB)
Title: Improvements in or relating to brakes
IPC: B60T13/36
Filed: 1939-07-06
Abstract: 531,692. Fluid-pressure brakes. BENDIX WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. July 6, 1939, No. 19748. Convention date, July 7, 1938. [Class 103 (i)] Devices are interposed in the conduits through which two or more brake actuators or cylinders are supplied which act in response to the flow of pressure fluid through the devices to delay the rise of pressure in one actuator or set of actuators relatively to that in another actuator or set. As applied to a vehicle or train of vehicles the application of the brakes may thus be effected in succession commencing with the rear brakes. The device shown in Fig. 1 com-. prises a casing 5 to which are connected conduits 31, 32 leading respectively to front and rear brake actuators. A nozzle 13 connected to the drivers' valve 19 projects into a restricted part 7 of the passage in the casing. When the valve 19 is operated to connect the nozzle 13 to the reservoir 16 the flow through the nozzle to the rear brake actuators produces a vacuum in the part 8 of the passage so that the front brake actuators are partially evacuated until the supply through the valve 19 is stopped, the pressure in the two pairs of actuators then equalizing. The valve 19 shown is of the self-lapping type in which the supply stops when the operating lever is held in an adjusted position. As applied to a train of vehicles a device such as 5 is disposed on each vehicle in the main conduit which extends along the train, the nozzle 13 being connected to the forward part and the pair of passages 11 to the rear part of the conduit on each vehicle while the branch pipes 31 are connected to the brake actuators of the vehicle. The application of the brakes thus occurs in sequence from the rear. During release of the brakes the devices 5 have no effect on the return flow of the pressure fluid and the actuators nearer the valve 19 tend as usual to exhaust more rapidly than those to the rear. The Specification as open to inspection under Sect. 91 describes also an alternative device, Fig. 3 (Cancelled), which is connected to the drivers' valve and to the front brake actuators by passages 48, 53 respectively and to the rear brake actuators by passages 49. A valve 54 having a restricted port 55a is normally held in the position shown by a spring 57 to allow free flow through the passage 53 as well as through the passages 49 but if during a brake application the flow is sufficient, the valve is caused to seat on the end of the passage 53 thus restricting the flow to that passage and the front brakes. This subject-matter does not appear in the Specification as accepted.

IPC: H03H9/08
Filed: 1960-06-03
Abstract: 934,191. Automatic temperature control. MINNESOTA MINING & MANUFACTURING CO. June 3, 1960, No. 19783/60. Class 38 (4). [Also in Group XIII] In an automatic temperature control system for a crystal oven, a switch responsive to the temperature within the oven controls the electrical supply to thermoelectric junctions inside and outside the oven so that the oven is heated and/or cooled as necessary to maintain the temperature constant. In Fig. 1 a piezo - electric crystal 22 is mounted between electrodes 24, 26 loaded by a spring 28 within an insulating chamber 12 having a cap 14. A bimetallic strip 68 responsive to the temperature within the chamber adjusts the position of a contact 70 so that if the temperature within the chamber rises above a value determined by the setting of a contact 72 a circuit is completed to pass current from a D.C. source 80, 82 through dissimilar semi-metallic elements P, N in such a direction that heat is absorbed by the thermo-electric junctions within the chamber and exhausted by the junctions outside the chamber. The temperature within the chamber is thus maintained constant at a value below the ambient temperature so that the frequency of a valve oscillator 86 associated with the crystal is constant. Suitable materials for the thermoelectric junction elements are described. In a modification, Fig. 3 (not shown), bimetallic strip 68 controls a two-way switch so that current is passed in one or other direction through the thermo-electric junctions to heat or cool the chamber as necessary to maintain its temperature at a value below, at, or above ambient temperature.

Abstract: 753,090. Batteries, electrolytic capacitors. MALLORY BATTERIES, Ltd. July 7, 1954 [Aug. 7, 1953], No. 19874/54. Classes 37 and 53. A leak-proof primary or secondary cell, electrolytic condenser or rectifier having a metal casing 24 is closed by a cover consisting of two metal plates 18, 19 which are separated from the casing by an insulating grommet 23 and which may be dished as shown and welded together at 20 to prevent relative movement. The edges of the plates may be slightly separated so that the material of the grommet is forced into the space so formed as shown at 28 when the upper end 27 of the casing is pressed inwards against the grommet. The plates 18, 19 may be made of nickel-plated steel and tin-plated steel respectively. Any electrolyte that may creep round the plate 19 becomes trapped between the two plates. The Figure shows the casing and cover applied to a primary cell comprising a steel can 10 enclosing a depolarizer 12 of mercury oxide and graphite separated by layers 15 of paper or other absorbent material from an anode 14 of compressed amalgamated zinc powder. The layers 15 are saturated with an alkali metal hydroxide solution containing dissolved zinc. An insulating spacer 16 of neoprene &c. separates the anode 14 from the base of the can 10. Any excessive pressure due to gas evolved in the cell produces a small relative movement between the can 10 and cover plates 18, 19 and gas passes between the part 22 of the grommet and the flange 11 of the can into the space 29 and is released between the bottom 26 of the can and the inwardly turned edge 25 of the casing. The space 29 may contain a sleeve 30 of paper or other porous material to absorb any electrolyte entrained in the escaping gas. In a modification the part of the casing 24 below the flange 11 is dispensed with and the part 27 is formed integrally with the can 10. Specifications 610,719, 669,833 and 680,697 are referred to.
