Title: Improvements in and relating to electrochemical cells
Inventor: MITCHINSON RONALD HUGH
IPC: H01M6/32
Filed: 1969-04-30
Abstract: 1298812 Metal-air electric-cell ENERGY CONVERSION Ltd 23 April 1970 [30 April 1969] 22023/69 Heading H1B A replaceable electrolyte reservoir adapted to be mounted on a metal/oxygen (air) cell contains sufficient electrolyte for full discharge of the cell. Alternatively the reservoir may be included in a replaceable anode. In one embodiment Fig. 5 the reservoir 40 is mounted on cell casing 41 which carries externally protruding hollow pins 42 which are received through apertures 43 in reservoir wall for transferring electrolyte from reservoir 40 to cell 41. The apertures 43 are sealed by a disc of self-sealing material. In another embodiment, Fig. 1, a replaceable anode comprising active portion 11, e.g. zinc and outer peripheral framework 12 is topped by housing 13 which contains a sealed flexible bag type reservoir 14 containing electrolyte, e.g. aqueous KOH. Reservoir 14 is punctured by pin 15 attached to housing 13 which is actuated by rod 17 in passage 18 formed in anode framework 12 when it contacts a protrusion in the cell on insertion therein. Wicks 19 may be provided which extend from housing 13 to the active portion of the anode. In another embodiment a sealed passage is formed in the peripheral framework of the anode which leads to the reservoir. Another passage is provided on the other side of the seal remote from the reservoir which leads to the active material. The seal is broken by on protrusion carried on the cell upon insertion of the anode. In a further embodiment the reservoir is mounted above the anodic active material and when this assembly is inserted in the cell it is activated by pressing on a weakened portion of the reservoir head which causes an internally protruding member to fracture a weakened portion at the bottom of the reservoir.

Abstract: 1,181,872. Thermistors; holding devices. INSTITUT PROBLEM MATERIALOVEDENIA AN USSR. 15 May, 1967, No. 22405/67. Headings H1K and H1P The sensitive semi-conductor element 1 of a thermistor intended for measurement of surface temperature is made of a magnetized ferrite, e.g. barium ferrite, so that the thermistor may be held in contact with the surface by magnetic attraction either to the surface itself, if it is ferromagnetic, or to a complementary magnetized piece placed on the opposite side of a non- magnetic wall whose temperature is to be measured. In the embodiment two barium ferrite elements 2, 3 are separated by a "cold" silver electrode 4 welded to a terminal 12, and are surrounded by a "hot" silver electrode 5 welded to a terminal 11. A diamagnetic heatconducting sleeve 7, e.g. of copper, and a magnetically non-retentive metal casing 6 covered with thermal insulation 10 surround the element, and an iron layer 8 coated with a metal layer 9 contacts the surface to be measured, and the electrode 5. The element may alternatively be separated from the casing 6 by an air space. The contact face of the device is shaped to conform to the surface under investigation.

Abstract: 309,112. Dean, H. May 22, 1928. Delivery of articles stored in piles; coin action, weight; coin-discharging mechanism.-In a coincontrolled vending machine of the type comprising more than one pile of articles arranged in line and a rotary ejecting member to deliver an article from each pile in succession, the rotary ejecting member is so constructed as to deliver square-edged articles of a size larger than its radius or cylindrical articles of a size equal to its diameter, thereby enabling a machine of reduced depth to be employed. The articles which are stored in magazines N, Fig. 1, are delivered by a roller 3 having recesses C, C<1> under each magazine, the recesses being arranged at right angles to each other, and adapted to take articles having a seating larger than the radius of the roller. The roller has projections D<1> - - D<4>, Fig. 3, at one end engaged by a pivoted catch A. A coin inserted in a shoot 2 engages the tail A<1> of the catch to allow the roller to be rotated by a handle L, the coin resting on an arm H extending from a stop 4 pivoted at K. During the rotation of the roller, one of the projections D<1> - - D<4> engages another arm J and moves the stop against a spring 5 to allow the coin to drop, thereby permitting the catch A to re-engage the roller after a quarter revolution. The roller may be constructed as shown in Fig. 4 to deliver articles in succession from four piles.

Abstract: 461,259. Lenses. KODAK, Ltd. Aug. 13, 1935, No. 22792. Convention date, Aug. 18, 1934. [Class 97 (i)] [Also in Group XXXVIII] An optical system for use in sound recording or reproducing apparatus comprises a single lens for forming a reduced image of the light source on a film, the lens having a short focal length and having the face thereof which is the nearer to the source aspherically curved about axes at right-angles to the length of the film, so as to correct for spherical aberration. As shown, a short-focus lens 11, which images an elongated light source 10 on a film 12, is preferably made together with a block 17 from a single piece of glass, and has a front aspherical cylindrical surface 15 and a rear plane surface 16. The surface 15 is almost a parabola. Glass of low dispersion is used, to reduce chromatic aberration. Means such as a slotted diaphragm 13 are provided, to limit the length of the image. In the arrangement shown, the lens employed makes possible a very short over-all distance from the filament 10 to the film 12, and the lens may have a working aperture of F 1À0, with freedom from spherical aberration and a magnification ratio of twenty to one. Instead of the lamp filament 10, a slit illuminated through a condensing system may be provided. The proper curvature of the lens 11 is determined in accordance with a given formula.

Abstract: 205,943. Lawrence, E. M., and Richardson, G. T. Aug. 23, 1922. Striking plates and staples for locks and latches.-A spring plate is mounted in the crack between the door and door-jam, to prevent the insertion of a gimlet or like tool from the outside of the door, into the crack to force back the latch-bolt. The plate 17, may be made of springy metal, or may be spring-controlled and is mounted adjacent to the lug L of the striking plate 15 which enters the crack 12 across which it extends to engage the edge of the door 10 when the door is closed. The edge 20 of the plate 17 is sharp so that it makes a close contact with the door-edge. A gimlet or like tool inserted through the material of the door-jam 11 to enter the crack 12, is deflected by the plate 17 and cannot force back the latch-bolt 14 of the lock 13. The plate 17 may be mounted on the lug L of the striking-plate as shown in Fig. 1, or between it and the door-jam and may be bent so as to allow the lug L to be fitted flush with the door-jam. The plate 17 may be fitted to the edge of the door and may be secured by screws passing through one elongated slot 18 or a pair of elongated slots 21, to allow of vertical adjustability, or it may be secured by two plain screw holes 22.
