Patent GB-810129-A (GB)
Title: Control systems for electrically driven vehicles
IPC: B60L15/04
Filed: 1955-12-20
Abstract: 810,129. Controllers. ZAVODY V.I. LENINA NARODNI PODNIK, NOVOTNY, B., and OPIAL, M. Dec. 20,1955, No. 36527/55. Class 38 (3). A master controller 1 for an electric vehicle is driven by a pneumatic pilot motor 4 which is regulated by electro-magnetically operated valves 5, 6. To start the controller, a main switch 16 is closed to energize valve 5 through resistor 7 and cam-operated contacts E, 11, F, on the controller. The controller moves to its second position in which the contacts E, 11, F, are opened, but the circuit to the valve 5 is maintained through contacts A, 9, B, on the controller. If the switch 16 remains closed, the valve 6 is energized through resistor 8 and contacts H, 12, G, and the pneumatic motor thus turns the master controller to its third position wherein the contacts H, G are bridged by the contacts C, 10, D which take over their function. In the third position of the master controller, the valve 5 is shortcircuited by contacts L, 14, M so that the pneumatic motor receives a further impulse for turning it to the next position. In its fourth position, the controller short-circuits the valve 6 by means of contacts K, 13, J, whereupon the controller is placed by the action of the pneumatic motor into its fifth position. If, during movement of the master controller, a relay 17 opens its contacts, the pneumatic motor is stopped. Reverse movement of the master controller is effected by actuating a changeover switch 15 to its alternative position. When the vehicle consists of a number of separate units, the pneumatic motor in one unit is regulated through contacts on the controller in another unit so that all the controllers throughout the train are regulated from a single position, Fig. 2 (not shown).

Abstract: 1,081,853. Weighing apparatus. MULLARD Ltd. June 13, 1966 [Aug. 27, 1965], No. 36899/65. Heading G4H. In weighing apparatus in which the unknown load 4 is placed on one arm 1 of a rigid beam 1, 2 and a transparent counterbalance weight 9 is rolled along the second arm 2, the counterbalance weight 9 focuses light from a source 12 on to a lined screen 7 beneath the beam 2. The light is reflected on to a photo-cell 14 so that as the weight 9 passes over lines of the screen 7 the photo-cell receives a series of light pulses which are converted into electric pulses and passed to a counter in indicator means 16. The count is stopped when the weight 9 passes the balance point, since the beam 1, 2 then rotates clockwise about its fulcrum 3 so that a switch 6 is operated. The count may also control the pointer of a meter. The counterbalance weight 9, which is a sphere with magnetizable arms, is initially released by de-energizing an electromagnet 17 and returned to the fulcrum 3 by an airgun 15 or pneumatic means. If the arms 1, 2 are both made horizontal the movement of the weight 9, may be initiated by an airgun or pneumatic means.

Title: Electric switch for electrolytic cell
IPC: H01H33/00
Filed: 1959-11-06
Abstract: 930,273. Mercury switches. ORONZIO DE NORA IMPIANTI ELETTROCHIMICI. Nov. 6, 1959 [Nov. 22, 1958], No. 37683/59. Class 38 (5). An electric switch comprises two interconnected chambers partially filled with liquid metal, a conductor extending into the liquid of one chamber and then passing through the interconnection and rising within the liquid in the other chamber to just below the surface level. A switch for switching out an individual cell in an electrolytic process comprises a container 7 separated into two compartments by a partition 8 and normally vented to the atmosphere at 10, 11 so that a quantity of mercury assumes a free level 9 in each compartment. Pressure at vent 10 or suction at vent 11 raises the mercury level in the lefthand, and lowers it in the right-hand, compartment. In the normal condition conductors 6 and 6<SP>1</SP> are connected together to provide a circuit from the cathode of the previous cell to the anode of the switched cell, thus putting the cells in series connection. As the mercury levels change owing to the applied pressure difference, all three conductors 5, 6, 6<SP>1</SP> are first connected together, shortcircuiting the anode-cathode path of the switched cell. As the difference in mercury levels increases the conductor 6<SP>1</SP> leaves the mercury, thus breaking the short-circuit and leaving a by-pass circuit around the cell via conductors 5 and 6. In a modification (Fig. 3, not shown), only two conductors 5 and 6 are employed, which merely short-circuit the switched cell. The switch casing may be metallic and may have an insulating lining 7. The end-cover plates may be of transparent material, e.g. acrylic resin, and arc distribution may be improved by slotting the ends of conductors 5 and 6<SP>1</SP>. Specification 785,932 is referred to.

Title: Barrier materials in the manufacture of explosives containing ethylene glycol dinitrate
Inventor: WILLIAMS ALBERT FREDERICK
IPC: C06B25/10
Filed: 1961-10-20
Abstract: In the manufacture of explosives containing a proportion of ethylene glycol dinitrate, polypropylene or polyethylene terephthalate in sheet form is used as a barrier material against the migration of ethylene glycol dinitrate. The barrier material may be in thin flexible or rigid laminated form and may be used for vessel linings or covers, or for gloves, aprons, or the like.  The sheet material may be modified by including minor proportions of ingredients which will reduce the tendency to acquire electrostatic charges, for example by inclusion of polystyrene containing quaternary ammonium salt groups in polypropylene sheet as described in Specification 946,824.  A laminated sheet of polyethylene and polyethylene terephthalate is effective against both water vapour and ethylene glycol dinitrate.  The barrier material may be tested for permeability to ethylene glycol dinitrate by a method identical with that described in Specification 948,286 using the explosive composition disclosed therein or a composition containing ethylene glycol nitrate and kieselguhr.
