Title: A method of producing a white-firing kaolinitic clay
Inventor: WINDLE WILLIAM
IPC: C09C1/42
Filed: 1962-08-03
Abstract: A white-firing kaolinitic clay is produced by subjecting a kaolinitic clay slurry to a non-homogeneous magnetic field having an average strength of at least 10,000 gauss in order to separate paramagnetic (e.g. ferruginous particles therefrom.  A suitable apparatus is described in Specification 768,451.  The particle size is preferably 5-75 m .  The slurry concentration may be e.g. 20-30% solid.

Title: Improvements in or relating to manoeuvre indicators for use on motor road vehicles, boats and other vehicles
IPC: B60Q1/14
Filed: 1934-10-22
Abstract: 446,012. Road - traffic signals on vehicles. LEATHERDALE, A. J., 32, Lower Kennington Lane, London. Oct. 22, 1934, No. 30233. [Class 118 (ii)] In a direction-indicator control switch, mounted on the steering wheel, set by hand and restored by the return movement of the wheel, the restoration is controlled by wedgeshaped members mounted on a spring-pressed plate in the switch and frictional contact between parts of the switch and a stationary member. As shown in the Figures, when a turn is to be indicated the handle 19 is depressed and moved to the right or left, the spring blade 28 moving with the handle between guide 30 and wedge-shaped members 35 (see Fig. 6), whilst contact 25 is moved to connect with brush 5 or brush 6 connected to the indicators over rings 7 and 8 respectively. When the steering wheel is returned the spring 28 rides up one of the wedge members 35 and member 37, which is connected to handle 19, is forced against the resiliently mounted fixed plate 38 and holds the handle against movement. As the steering wheel is returned, spring 28 moves back to slot 29 and the handle 19 moves upward into its normal position. The rings 7 and 8 are mounted on the steering column and the switch mechanism is fixed to an arm of the steering wheel 1 by clamp 3, the handle 19 passing around the arm. Specification 398,537 is referred to.

[Also in Group XL (a)] A selective signalling device comprises a discharge tube in which the arc can be deflected by electric or magnetic fields to touch auxiliary contact electrodes. The arc 7, Fig. 2, between an anode 2 and a cathode 3, can be deflected by a field coil 14 on to a preselected contact electrode 8 ... 12, 18, each of which is included, together with the anode or cathode, in independent circuits. The appropriate contact electrode can be selected by adjustment of the field current, e.g. by selection of one of the resistances 17, by displacement or shunting of the magnet or by adjustment of the arc current. A secondary discharge between a selected pair of contact electrodes 24, Fig. 4, to close an auxiliary circuit may be caused by deflection of the arc by two magnetic coils 14, 20 at right angles to each other. The tube may comprise four columns each containing five pairs of electrodes. They may be arranged so that a number of circuits are closed simultaneously.

Abstract: 191,899. Weight, W. C. Nov. 21, 1921. Couplings, automatic.-In an automatic coupling for railway vehicles in which the hook-bar is pivoted about a horizontal pin and which engages in a horizontal plane, the hook-bar is adapted for pivotal mounting in the heel of the usual draw-bar hook or in the end of the draw-bar and is provided with a spring controlled guide arm which extends laterally in a position facing the hook. The hook-bar a is pivotally mounted on a horizontal pin a<2> through the hole in the chain coupling hook b or to the end of the draw-bar, the ends of the pin a' bearing against a centralizing spring d. The hook-bar a is provided with a spring contrdlled, pivoted, guide k and with a plate or rod I pivoted on the upper side which provides a rest for the opposing hook when uncoupling. The hook-bar is raised in a vertical plane by a lever e fixed to a transverse shaft f operated by a side handle g, the lower end of the lever e being provided with a spring plunger e<3> which bears against the jointed end of two levers h, Fig. 2, to retain the hook-bar in the horizontal position for coupling, and which can be moved out of the way to allow the hook-bar to fall and allow the ordinary chain hook b to be used. Coupling is effected by retaining the hook-bars a in the horizontal position and running two cars together, the hooks being guided into engagement by the guides k. When uncoupling, one hook bar is raised by the lever e until the pivoted bar l on the opposing coupler is free to drop back on to its hook. The hook-bar is then lowered until it rests on the bar l; the vehicles can then be separated.

Title: Electronic data processor with provision for error diagnosis
IPC: G06F11/07
Filed: 1972-07-04
Abstract: 1390438 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 4 July 1972 [30 July 1971] 31149/72 Heading G4A A data processor includes two serially connected gates, an error checking means responsive to data at the output of the second of the gates and operative, in the event of an error, to inhibit both gates so that the same operation is repeatedly performed on the same data in the part of the processor between the gates. As described two operands OPD1 and 2 and an operation code OPC are read into respective registers from a central store (not shown) via gates G1-G3. A control unit CU responds to the operation code to control an arithmetic and logic unit ALU to perform the required operation on the operands, the result being fed via gate G4 to a result register. A parity check circuit PCH monitors the output of the ALU and in the event of an error sets latch CH-FL. The set state of the latch illuminates a warning lamp CHL and also, via control unit CU, inhibits gates G1-G4. Thus the operands and operation code remain in the section of the processor between gates G1-G3 and G4 and the same operation is repeated in response to continued operation of the processor clock. The data relating to the erroneous operation is thus held for subsequent analysis. The gates may be opened either manually or under program control to allow further processing to continue.
