Abstract: 328,300. Tann, J. L., and Tann, Ltd., J. Jan. 25, 1929, Receiving and delivering devices for doors and the like.-Means for introducing deposits &c. into the safe or strongroom of a bank &c. from the exterior thereof after normal business hours comprises a compartment-carrying member K which moves about a vertical axis from a position in which the compartment J is accessible to authorized users through a door opening A to a position at which it delivers the deposit into the safe or strongroom D; in moving to the delivery position the deposit may be positively ejected from the compartment into the opening or shoot 0 giving access to the safe &c. D. As shown, the opening 0 is in a casing C in which the member K, disposed in an inner casing C<1>, is mounted on a vertical shaft L and pinions M, secured to the shaft, engage racks N on arms F, F<1> connected to the door E, the arm F being rotatably mounted on a pivot G and a spring H tending to close the door over the opening A. When the door is unlocked and opened the deposit, placed on the bottom of the casing C<1> in the open-bottomed compartment J is carried by the sides of the compartment over the bottom of the casing C<1> to the opening 0, but a false bottom Q pivoted about the shaft L may be provided to avoid the resistance due to friction between the deposit and the bottom of the casing C<1>; the false bottom moves with the shaft L by friction until it meets a stop R when the further movement of the compartment J sweeps the deposit off the bottom Q into the opening 0. On the closing of the door E and return of the compartment J, the bottom Q is returned to a stop T by a tappet S on the casing K. The deposit may be positively ejected from the compartment J by a curved blade pivoted to the top of the casing C<1> to ride freely on the top of the casing K and pass through a slot in the top of the compartment and sweep out the deposit into the opening O. Specifications 308,855 and 325,361 are referred to.

Title: Battery charging systems for road vehicles
IPC: H02J7/24
Filed: 1971-01-22
Abstract: 1367897 Vehicle battery charging systems JOSEPH LUCAS (INDUSTRIES) Ltd 10 Jan 1972 [22 Jan 1971] 2938/71 Heading H2H A system for charging the battery 21 of a road vehicle from a multi phase alternator 11 and a full wave rectifier 15, 16 comprises a warning lamp 27 connected in series with the field winding 28 of the alternator and a thyristor 29 which receives gate current as long as the battery voltage is below a predetermined value. The thyristor 29 is switched on by the voltage across a resistor 33 and when an ignition switch 22 is closed, a transistor 24 conducts to illuminate the lamp 27. When the alternator is producing an output, the voltage at the junction between the lamp 27 and the winding 28 rises to switch off the lamp. When the battery voltage reaches the predetermined value, a Zener diode 36 conducts, thereby switching on a transistor 32 to prevent the gate signal being applied to the thyristor 29. The current in the field winding 28 is therefore switched off.

Abstract: 1366541 Fibre containing ferrite composition JOSEPH LUCAS (INDUSTRIES) Ltd 19 Jan 1972 [26 Jan 1971] 3146/71 Heading C1J In a method of making a ferrite magnet in which a starting material is sintered to form a ferrite magnet material, is pressed in a magnetic field to the shape of the required ferrite magnet and then, after subsequent demagnetization, the ferrite magnet material is sintered to produce the required ferrite magnet, the improvement consists in mixing the ferrite magnet material with a fibrous material prior to pressing the ferrite magnet material in the magnetic field. In an example 83% Fe2O3, 12À8% SrCO3, 1À77% PbO, 1% CaF2, 1% Al2O3 and 0À5% Sr3(PO4)2 all in powder form, were mixed to produce a starting material which was calcined at 1260 C. for an hour to produce a ferrite magnet material. After ball milling in water, the slurry was mixed with alumino-silicate fibres, filter pressed in a magnetic field and sintered. Other compositions excluding Sr3(PO4)2 and Al2O3 are also disclosed. Cellulose fibres may be used in lieu of alumino-silicate fibres.

T., Blackbrook, Caerphilly, Glamorgan. Dec. 6, 1933, No. 3307/35. Divided out of 429,767. Drawings to Specification. [Class 40 (iv)] The input circuit of a non-contact-making relay such as a thermionic valve or gas discharge tube is connected to potential over a number of circuits so as to control the operation of apparatus, such as a contact making relay in its output circuit, in response to the opening of all the input circuits, e.g. when all such circuits are engaged. The circuit arrangements are identical with those described in Specification 429,767 which relates to a system using bi-directional regular and overflow finders such as described in Specification 376,265. The grid circuit of a thermionic valve or gas discharge tube is connected over the vertical wiper of each regular finder to idle battery, and a relay in the anode circuit brings in the overflow finders when all regular finders are busy. A similar arrangement is used with the overflow finders in order to connect up statistical meters and suspend the distributers when all the overflows are engaged. The Provisional Specification describes a different arrangement in which a contact-making relay replaces the valve or tube associated with the regular finders.

Abstract: 104,532. Beaumont, H. March 6, 1916. Shafts.-Crank-shafts for multicylinder engines for aeroplanes, motor-vehicles, &c., are made by forging between dies with hexagonal or polygonal recesses. The first recess c gives the bar, when cranks at 120 degrees are required, an hexagonal form, the second d flattens the bar at the point where a crank is required and the third! has cutters f which remove a part of this flattened portion thus finishing the forging of one crank. The bar is then turned through 120 degrees and the operation repeated on another portion of the hexagonal bar. The shaft is then corrected by placing over the crank portions hexagonal sleeves having recesses exactly corresponding to the finished size of the cranks and hammering the whole. The shaft is then machined to form the crank-pins.
