Title: Improvements in spring systems
IPC: B60B9/00
Filed: 1945-04-23
Abstract: 599,822. Clutches; linkwork. MORANESAULNIER. April 23, 1945, No. 10200. Convention date, April 17, 1944. [Classes 80(ii) and 80(iii)] [Also in Groups VII, XXXII, XXXIV and XXXVII] A spring mounting (see Group XXXII) is applied to a free-wheel mechanism, Fig. 17, the driven member of which comprises a non-extensible elastic band 1 having rigidly secured to itself the outer ends of arms 12 which are pivotally mounted on a central plate 13 keyed to the driven shaft. The pivotal points of the arms 12 lie adjacent the periphery of the plate 13 which is spiral-shaped, the arrangement being such that the band is constrained to maintain a truly circular contour under deformation. Clockwise movement of the driving member 50 relative to the driven member 1 tends to expand the latter and transmit the drive. As applied to a clutch, Fig. 13, a circular band 1 is connected by arms to a spiral-shaped central plate as in Fig. 17 above, and may be outwardly pressed while retaining a circular shape, by rotation of the plate by a lever 46 to urge driven clutch members 42, 43, slidably keyed on the driven shaft 41, into engagement with the driving member 44. The band 1 carries small rollers (not shown) around its periphery to prevent it wedging between members 43, 44. An application to motion reducing linkage, Fig. 18, comprises a spring band 1 connected by arms 12 to a spiral-shaped central plate 13 the arrangement being such that the deflection of a lever 52 connected to one end 1a of the band 1 is greater than that transmitted to a lever 55 connected to the other end 1b.

[Also in Group XXXVI] A two- or multi-layer film suitable as an electrode separator in a dry cell electric battery comprises a layer of a water-soluble non-fibrous alkyl cellulose ether or hydroxy- or carboxysubstituted alkyl cellulose ether or salt of a carboxy-substituted alkyl cellulose ether adhered by a partially hydrated alkyl cellulose ether or derivative as above to a layer of waterinsoluble alkali-soluble non-fibrous alkyl cellulose ether or an insolubilized film of a watersoluble alkyl cellulose ether. Typical suitable water-soluble non-fibrous cellulose ethers or derivatives are methyl or ethyl cellulose, hydroxyethyl or hydroxypropyl cellulose, and sodium carboxymethyl cellulose. The waterinsoluble ether layer may be formed by treatment of the water-soluble ether with citric or tannic acids or a melamine-formaldehyde resin as in Specification 603,927 [Group XXXVI] in the mix used for casting, and the water-soluble cellulose ether may be either (a) applied as a preformed film when the adhering material may be a preformed layer, paste, or dough of partially hydrated water-soluble cellulose ether or formed in situ on the water-soluble film by the application to either or both of the layers to be joined of an organic liquid which does not react with them, e.g. lower alkyl alcohols and ketones, containing up to 4 per cent water; or (b) spread as an aqueous self-adhering paste or dough. One of the two layers may contain an identifying dye. The film is dried e.g. at 130‹ C. under tension. If mercuric chloride is incorporated in the water-soluble layer for amalgamation with the zinc can of the battery which it contacts, drying should be effected at not more than 40‹ C. If desired, water-soluble cellulose ether layers may be applied to both sides of the waterinsoluble layer.

Title: Improvements relating to oil coolers
IPC: F16N39/02
Filed: 1941-08-20
Abstract: 549,591. Fluid-pressure servomotor-controlsystems. SERCK RADIATORS, Ltd., and WATKINS, C. Aug. 20, 1941, Nos. 10631 and 13402. [Class 135] [Also in Group XXXV] The invention relates to liquid coolers or heaters in which the cooling or heating is obtained by heat transfer between one liquid and air or other gas, and particularly to oil or water coolers on aircraft or land vehicles. A shutter controlling the flow of gas through the cooler or heater is operated by screw mechanism from reversible electric or fluid-operated motor which also operates through a second screw, a slidable control member which co-operates with a second slidable control member, operated in response to thermal conditions in the cooler or heater to control the motor. An electric motor may drive a worm i coupled to the shutter-operating screw e and to a screw k operating a slide carrying a contact o co-operating with contacts x on a slide w actuated by differential fluid pressures in a cylinder q. The opposite ends of the cylinders are connected by pipes to the 'inlet and outlet of the cooler. A change in viscosity of the oil will actuate the slide w and cause a change in the setting of the shutters c accompanied by a follow-up movement of the contact o. To overcome " coring" in the oil due to very low air temperature a thermostat device such as a metal bellows at the cooler outlet, which it can respond to the temperature of the oil core, may operate the control to cause closing of the shutters. The slide w may be operated preferably through a lost-motion connection by a thermostatic device responding to oil temperature in any convenient position.

Filed: 1942-07-30
Abstract: 574,221. Gun mountings. MOTLEY, L. July 30, 1942, No. 10668. [Class 92 (i)] In a gun mounting, such as described in Specification 573,979, in which a plurality of guns, spaced apart laterally, are adapted to be traversed. in unison about individual axes relative to a support, which is also adapted to be traversed relative to a fixed base, the training movement of the guns automatically operates an electric, or fluid-pressure, motor, for rotating the support to follow up the guns until the normal relative position is restored. As shown, gun arms 2 with operating handles 4 are interconnected for movement in unison about parallel training axes L-L and for simultaneous elevation about a common axis M on a seat 1 for the gunner carried by a shaft 24 connected with the motor 13, or 37, on the underside of the base 26, through a one-way transmission, such as a worm wheel 27 and a worm 28, for preventing rotation of the support if one of the guns should misfire. In the case of an electric motor 13, a contact arm 21 is moved by piiis 29 with one of the arms 2 over resistances 22, 23 on the underside of a hooded plate 30 to operate the motor in one direction or the other, the speed of the motor increasing with the length of resistance in circuit. One terminal 14 of the motor is connected through the supply source and a slip ring 32 to the arm 21 and the terminals 18, 19 through slip rings 35, 36 to the outer ends of the resistances respectively, the leads from the slip rings passing through the shaft 24. In the case of a fluid-pressure motor 37, a reversing valve 50, Fig. 9, for supplying the motor from a source of constant fluid pressure may be operated through a link 49 and a bell-crank lever 48, Fig. 8, having, a bifurcated arm 46 terminating in rollers 45 engaging a groove 44 on a sleeve 41 connected by a pin 42 with one of the runs of a cable 39 passing over a pulley 40 and connected at its ends to one of the gun arms 2. The cable 39 passes through Bowden casings 52 secured to arms 53. Alternatively, the motor 37 may be operated by a continuously driven variable-stroke reversing pump connected with the bell-crank lever 48. In either case, the speed of the motor increases with the movement of the guns from the normal relative position. The seat 1 may be replaced by a turret. The guns may be traversed and elevated by respective prime movers, such as hydraulic rams controlled by levers.
