Abstract: 1,115,599. Sewing machines. INSTITUT FUR TEXTILMASCHINEN. 17 Oct., 1966, No. 46343/66. Heading DIG. In a sewing machine comprising a carriage movable in two directions at right angles to one another by longitudinal and transverse transport means respectively and guided by engagement with a stationary template, the carriage is resiliently connected to a workholder, and the latter is disconnected at the end of a sewing operation by abutment wilth a fixed stop, the carriage thereby being returned to its starting position by the longitudinal transport means, and the workholder then being transferred by further tranverse transport means to further longitudinal transport means effecting the return of the workholder to its starting position. A workholder 18 has a vertical bar 15 movable between a row of upright studs 14 on a bar 1 to 'be held therein by a ball catch 16. Bar 1 is supported by a rod 2 which slidably engages a template slot (5) in a fixed plate, and which is rigid with a carriage (4) slidable transversely on a carriage (8), the latter being movable longitudinally by driven endless chains (6) (7) on rails (10) (11), and carriage (4) being moved transversely by means not described. At the end of a sewing operation, workholder 18 is halted by engagement with a needle-guiding boss 20, and is disengaged from bar 1 on further movement of the chains (6) (7). A bar 25, which journals a rod 26 rigid with fingers 27 biassed to the horizontal position by a spring 28, is then driven by an endless chain transversely towards the stationary workholder. The fingers 27 are moved to the upright position by engagement with a fixed abutment, and are held upright in engagement with bar 15 by a spring catch carried by bar 25. The latter is then driven to shift work holder 18 forwardly, the left hand end of the workholder being supported by the sewing machine table and the right hand end being supported by a rod 41 slidably mounted in bar 25 and spring-biased outwardly. Near the end of the forward travel of bar 25, bar 15 rides up a cam surface on a fixed bar 37 to lodge in a groove 38 therein; the fingers 27 passing into recesses 40 provided in bar 37, and the spring catch holding the fingers 27 upright being released by co-operation with a fixed abutment 34. An endless longitudinal chain 33 is then driven to engage a pin (35) thereon with a hook 36 on workholder 18 for shifting the latter to an unloading position.

Title: Safety belt anchor system
IPC: B60R22/343
Filed: 1965-11-03
Abstract: 1,112,073. Safety harness. A. G. CARTER. 3 Nov., 1965 [19 Nov., 1964], No. 46644/65. Heading A3V. [Also in Division B7] A spring reel 23 for a vehicle safety belt is locked against rotation in the unwind direction by engagement of a toothed clutch plate 35 with a toothed portion 24 of the reel, means for biasing the toothed members into locking engagement, namely a spring 44, levers 46 and 39 and an actuating rod 38, being released on uncoupling of the two portions of the buckle which causes energization of a solenoid 43 associated with the spring 44 and lever 46. Should the electrical -system fail in a crash the reel will therefore remain locked. The teeth 33, 34 have slanting faces allowing rotation of the reel in the wind-in direction in ratchet fashion when it is locked against rotation in the opposite direction. The solenoid is connected to the vehicle ignition circuit, Fig. 9 (not shown), and is de-energized when a shunt circuit is completed on connection of the buckle portions (56), (57) (Fig. 8, not shown). Conductor wires (58), (59) are incorporated in the belt sections and current passes from them through the reel 23, shaft 16, mounting frame 10, shackle 12 and bolt 11 to a wire 68 incorporated in the circuit. In an alternative arrangement, Fig. 10 not shown, the circuit to the solenoid is completed by operation of a pressure-sensitive switch actuated only when the vehicle seat is occupied. The frame 10 is mounted in a housing 83 and is pivotable relative to the vehicle floor through the shackle 12, eye bolt 11 and pin 13.

Title: Rechargeable electrochemical generator arranged to operate with an alkaline electrolyte
IPC: H01M12/08
Filed: 1970-10-02
Abstract: 1286173 Hybrid air-secondary cells COMPAGNIE GENERALE D'ELECTRICITE 2 Oct1970 [6 Oct1969] 47070/70 Heading H1B A rechargeable cell comprises an air electrode 1, e.g. a sintered nickel support impregnated with a catalyst, a metallic electrode 2, e.g. of iron or cadmium, and an alkaline electrolyte, e.g. potassium hydroxide, in which the metal of electrode 2 is insoluble. In use, the electrolyte needs to be decarbonated from carbon dioxide adsorbed from the air. To this end, the electrolyte compartment is divided into two sections 4, 5 by a cation exchange membrane 3. As shown, the membrane is disposed between the electrodes 1, 2 but in a modification (not shown) the membrane is disposed between the electrode 2 and a counter electrode serving as the decarbonating electrode. Fig. 1 shows the discharge reaction in which the electrolyte content increases in compartment 4 and decreases in compartment 5; also, the electrolyte in compartment 4 becomes carbonated and KOH forms a layer on electrode 2. Before the dilution of compartment 5 is complete the discharge is stopped and the cell is recharged. The charge current causes the electrolyte content of the two sections 4, 5 to become equal but after this state is reached the charge current is maintained so that the pH value of the electrolyte in compartment 4 is lowered to about 7 or 8 and the unwanted carbon dioxide is liberated. At the conclusion of this treatment the compartment 4 contains pure water and before the cell can be used this electrolyte must be made conductive. This may be achieved by not using the cell for a short time to permit K<SP>+</SP> ions to enter the compartment 4 from compartment 5; alternatively, to permit immediate use of the cell, a current is passed through the cell for a very short time in the discharge direction.

Title: Improvements in and relating to control rods for nuclear reactors
IPC: G21C7/107
Filed: 1968-10-10
Abstract: 1,204,938. Reactor control rods. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 10 Oct., 1968 [11 Oct., 1967], No. 48160/68. Heading G6C. A control rod freely insertable into a loose pile of fuel elements, in particular spherical fuel elements, is hollow and has within its interior at least one channel for receiving fuel elements the channel communicating with an opening in one end of the control rod of such a size that the fuel elements are admitted into the channel one at a time during the insertion of the control rod. The resistance to the insertion of the rod is thus minimized, resulting in a low breakage percentage in the pile of fuel elements, and the use of fuel elements that are particularly crush resistant is unnecessary. Preferably, the channels in the rod interior are formed by partition members, a simple member comprising two relatively perpendicular walls being sufficient for dividing the rod interior into four channels. The cross-section of the rod may increase in the direction away from the opening(s), either gradually or abruptly. Preferably, a control rod having abrupt changes in cross-section contains additional channels originating where the cross-section changes and provided with openings for the reception of further fuel elements. The abrupt changes in cross-section may be created by telescoping several control rods together. The end of the control rod may be adapted to the shape of the fuel elements and may be blunt, coned or formed with one or a plurality of tapering faces.

Abstract: 1,129,477. Measuring rotary unbalance. H.R. TEBBOTH. Nov.29, 1965 [Nov.27, 1964], No.48393/64. Heading G1N. The angular position of an unbalanced mass on a vehicle wheel is determined by generating signals upon passage of a mark on the wheel past a fixed point and comparing the phases of these signals and signals from a vibration transducer. The wheel is resiliently suspended, for example in the vehicle suspension system, and is rotated at a speed at which vibrations due to the unbalance are in resonance with the suspension system. The output from the transducer is squared and differentiated and the resulting pulses are applied to one stage of a bi-stable multi-vibrator. Passage of an illuminated mark past a photo-cell, e.g. a photo-transistor, generates pulses which are applied to the second stage of the multi-vibrator. The average current through the latter stage is measured to indicate the phase difference between the pulse trains and a part of this current is also supplied through a resistor to a capacitor for storing the reading. The output from the transducer, or from a second transducer having common mechanical components with the first, is passed to an integrating amplifier the output of which is proportional to the vibration amplitude and inversely proportional to the square of the vibration frequency. This output is used to estimate the magnitude of the required balance weight. The wheel is rotated either by the vehicle engine or by a roller driven by an electric motor and is then allowed to run down until resonance is indicated by a maximum output from the integrating amplifier. The apparatus may be modified for measuring dynamic unbalance by providing a further transducer at right angles to the first or by repeating the testing procedure with the transducer in a different position.
