Title: Improvements in and in the manufacture of layer type dry batteries
Inventor: LINTON ALFRED
IPC: H01M6/48
Filed: 1954-09-02
Abstract: 793,624. Dry batteries. BURNDEPT, Ltd. Aug. 31, 1955 [Sept. 2, 1954], No. 25523/54. Class 53. Adjacent cells of a layer-type dry battery are joined by metal sheets which are welded together in the middle and which are elsewhere spaced apart by plastic material adherent to both sheets and moulded into the form of a shallow cup to contain other elements of the cell. Fig. 12 shows a unit, comprising the components of one cell, which is made by forming a boss 2 on a steel disc 1 and moulding a layer 3 of polythene to the disc. The boss is then spot-welded to a steel disc 4, carrying a zinc or cadmium coating 5, and the unit is hotpressed so that the polythene fills the space between the discs and forms a cylindrical rim 6 around the discs. An anode, consisting either of a sheet of bibulous paper 7 provided with a coating 8 of zinc or cadmium or a pressing a pressing of zinc or cadmium powder, and a cathode, consisting of a sheet of bibulous paper or iron gauge 11 coated with a slurry of powdered cathode material 12 in a solution of sodium alginate, are placed within the cup formed by the rim 6 and are separated by a disc 13 of porous p.v.c. In another form, Fig. 13 (not shown), the rim extends both above and below the disc, the cathode being placed in the cup above the disc and the anode and the separator 13 in the cup below the disc. A battery is formed by sealing together the polythene cups of an assembled pile of units by rolling the pole under a hot bar, punching the edge of each cell by a comb 14 (Fig. 14), vacuum filling the battery with electrolyte and sealing the punctures by local heating or by sheathing with p.v.c. The ionstruction is stated to be particularly applicable to cells of the magnanese dioxide/zinc, mercuric oxide/zinc, silver chloride/magnesium and silver oxide/zinc types.

Title: Device for indicating the amount of displacement of a slide
IPC: G01D5/252
Filed: 1963-06-28
Abstract: 986,303. Electric selective signalling. M. HENSOLDT UND SOHNE OPTISCHE WERKE A. G. June 28,1963 [Aug. 24, 1962], No. 25757/63. Addition to 931,042. Heading G4H. In a displacement indicating device, an electronic number-indicating tube has its appropriate cathode energized (to indicate the displacement) via a relay-controlled switch, the relay being controlled by a brush sweeping contact. In Fig. 4, a millimetre scale 40 is swept as it moves by brushes A to D which control relays Ra to Rd the contacts S20 to S28 of which energize the appropriate cathode of a tube 20. A reversing switch 21 allows tube 20 to count in either direction and a zeroizing switch 24 allows the cathode leads to be interchanged. Relay Ra also selects leading or lagging brushes A1<SP>1</SP> to D1<SP>1</SP> or A2<SP>1</SP> to D2<SP>1</SP> on a centimetre scale 50 by means of contacts T20 to T23,the selected brushes controlling relays Ra<SP>1</SP> to Rd<SP>1</SP>. These relays energize one cathode of a second (centimetre) tube 30 in a similar way to previously except that, in order that the reading of tube 30 shall not change until a full centimetre has been travelled from an arbitrary zero position set by zeroizing switches 34, 24, relays R a <SP>1</SP> to Rd<SP>1</SP> control two relay trees II, III. These trees are connected to select adjacent cathodes of tube 30 for given states of relays Ra<SP>1</SP> to Rd<SP>1</SP> but only one tree is operative at a given time. The heads of trees II, III are connected by leads u,v to a switch 42 which is mechanically linked to zeroizing switch 34 and which connects leads u, v to appropriate cathode leads of millimetre tube 20 (details in Figs. 5, 6, not shown). Since only one of these cathode leads is energized at a given time, only one of leads u,v will be energized, depending on the position of switch 34 (via 42). The arrangement may be extended to higher decimal orders. Figs. 1-3 (not shown) show a simpler embodiment in which three brushes (in line on a single track of contacts) control a relay tree having eight output leads which are connected to five cathodes of a number indicating tube,the connections being such as to reduce errors due to inaccurate spacing of the brushes.

Abstract: 233,985. Thornton, J. E. Nov. 3, 1924. Addition to 224,569 and 224.573. Colour photography; films with multiple sensitive layers. - Film material used in the production of four or three colour kinematograph positive films as described in the parent Specification comprises a celluloid or like base of double standard width and half standard thickness upon each side of which are coated side by side two coloured colloid layers. The colours of the layers are all different if a fourcolour positive is required; for a three-colour positive one of the colours is duplicated in two layers. The colloid may be sensitized by treatment in a bath of bichromate, iron, or silver salts; or it may be coated in the form of a silver emulsion. The colouring matter may be added to the colloid before coating, or applied to the dried colloid layers after coating. In order that all four colloid layers may be printed simultaneously from full-tone negatives placed on opposite sides, a wash-out light-obstructing colouring-agent, such as tartrazin, is incorporated in known manner either in the substratum layer which unites the colloid layers to the base, or in the colloid layers themselves. When printing is effected from two two-colour component negatives placed on the same side of the material, this colouring agent is not required. Similar film material may be used for producing ordinary transparencies, such as lantern-slides and illuminated signs.

Abstract: 821,063. Vehicle power steering. CLEVELAND PNEUMATIC TOOL CO. Aug. 29, 1956 [Sept. 14, 1955], No. 26388/56. Class 79(5) In an aircraft steering mechanism comprising a ground engaging wheel (not shown) carried by a strut formed by telescopic and relatively rotatable shafts 10, 12, a sleeve 16 mounted by bearings 17, 18 on the shaft 10 carries the cylinder of a fluid pressure motor, the piston 33 of which is connected by a rod 32 to a ring 21 supported by bearings 25 on an ecentric cam 23 secured to the shaft 10, whereby pressurizing the motor causes relative rotation between the shafts, hence steering the ground engaging wheel. A: further shown, the invention is applied to a conventional aircraft landing gear strut, the shaft 10 being secured to the airframe and the shaft 12 earring the ground engaging wheel, the shafts 10, 12 being connected by an oleo mechanism (not shown). The ring-shaped cams 22, 23 are keyed to the shaft 10 at both ends of the sleeve 16, the cams rotatably carrying the rings 19, 21 interconnected by bolts 27. The sleeve 16 is adapted to rotate on the shaft 10 about an axis 26 coincidental with that of the shafts 10, 12, the sleeve 16 carrying lugs 65 on an enlargement 30 connected by torque arms 14 in the shaft 12 whereby the sleeve 16 and shaft 12 rotate in unison. The rings 19, 21 are adapted to rotate about an axis 24 relative to the cams 22, 23. The enlargement 30 is formed with coaxial bores 28, 29, the bore 28 containing a bearing sleeve 31 for a piston rod 32 and the bore 29 forming the cylinder. The bore 29 is sealed by a cap 34 and the piston 33 forms spaces 37, 38 in the cylinder. A boss 60 on the shaft 10 is connected to pipes 62, 63 leading to a control valve mechanism and a source of pressure (not shown). The boss 60 is connected by bores 56, 59 to ports 58, 59 in the shaft 10, the ports registering with grooves 44, 46 in the sleeve 16. The grooves 44, 46 are connected by bores 48, 50 in the sleeve 16 to the cylinder spaces 37, 38 whereby the spaces can be selectively pressurized by the source in order to give power steering of the wheel on the shaft 12. The piston rod 32 is connected to a pin 39 supported by trunnion mountings in the rings 19, 21. In order to prevent binding the arrangement is such that R, + A # R 2  where R 1  is the distance between the piston rod axis and the axis 26, A is the distance between the axes 24, 26 and R 2  is the distance between the axis 24 and the axis of the pin 39. The arrangement is such that the wheel can be rotated through 360 degrees and the arms 14 may alternatively be connected to the rings 19, 21 but complete rotation is not then obtainable. The control valve mechanism may include metering orifices to effect shimmy damping. In a modification, Figs. 7, 8 and 9a to 9f (not shown) the sleeve 16 is fixed to the shaft 10, the ring-shaped cams 22, 23 are rotatably mounted on the shaft 10 and the torque arms 14 are connected to the rings 19, 21.
