IPC: H01H50/28
Filed: 1963-11-05
Abstract: 1,100,154. Electromagnetic relays. PLESSEYUK Ltd. 28 Oct., 1964 [5 Nov., 1963], No. 43533/63. Heading HiN. A number of units 10 each comprising an armature 16 and associated contacts 21, 22, together with two polepieces 23, 24, are closely stacked to be operated by a common energizing coil unit 11. The assembly is held together by a bolt 31 passing through non-magnetic material 24a and also through spring clips 30 which hold the potted unit 11 on to the units 10 (Fig. 2, not shown). Each armature 16 comprises contact material 18, for example, silver, and is supported by a leaf spring 15 on a terminal pin 12a which with contact terminal pins 12b and 12c enables the assembly to be plugged into a standardized socket or a printed-circuit board. The connections to the energizing coil 28 may be brought out to terminal pins on the same face as pins 12. The polepieces 23, 24 are arranged as shown to give the armature a combined rotational and transverse motion.

Title: A system for numerical machine tool control
IPC: G05B19/4103
Filed: 1960-12-23
Abstract: 956,871. Numerical control systems. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Dec. 23, 1960 [Dec. 24, 1959; March 25, 1960], No. 44214/60. Heading G3N. The finished dimensions of a workpiece are considered to consist of a series of arcs and/or straight lines, and the beginnings and endings of each of these elements, with reference to a single datum point, are said to be transferred from a drawing 1 to punched tape, card, or magnetic tape together with some sort of machining instructions, and so supplied to a computer 3. As disclosed in Specification 953, 922 the computer 3 interpolates between the datum points and provides the X and Y co-ordinates of a series of points along the contour, in natural binary code and in parallel mode. The position of the tool or workpiece is said to be measured at 7 also in natural binary code, parallel mode, by a V-scan digitiser, and the two signals are said to be compared at 4 to control some unit 5. Since the computer 3 is said to be incapable of dealing with negative values, the basic point chosen must lie outside the workpiece; otherwise the coordinates of the desired datum point relative to the basic point are stored at 9 in a decimal register, converted at 10 to binary and added or subtracted at 11 from the data being supplied to the computer 3. The co-ordinates of the desired datum point may be found by positioning the work manually and reading the signal from 7 on undisclosed indicator 13.

A process for the agglomeration of at least substantially solid particles (e.g. of an adduct of a hydrocarbon with urea or thiourea) from a suspension thereof in a liquid, the said suspension comprising at least two solid components, comprises adding to the suspension a pressurized gas which together with an auxiliary compound present in and/or added at the same time to the said suspension and with at least one of the said solid components forms a binder liquid which preferentially wets the solid particles and is immiscible or substantially immiscible with the said liquid. The gas may be ammonia, methylamine, dimethylamine or trimethylamine. The auxiliary substance may be water, methanol, ethanol, isopropanol, ammonium nitrate, ammonium sulphate or ammonium iodide.

A riser shaft is located on each side of the intake of the pump P, part of the riser shaft wall being a part of the extractor outer wall and the other part of the shaft wall being curved to aid smooth flow. Openings O are provided in cover plates of the aprons located above alternate riser shafts in consecutive stages so that the lighter phase from chamber S n-1  ascends both riser shafts C n-1 , passes through openings O n-1  and up one of shafts C n  to enter mixing chamber M 2  where it mixes with the recycled lighter phase which ascends from chamber S n . The pump handles a volume exceeding the sum of the volumes of the liquids entering from previous stages, the recycled lighter phase making up the difference.

Abstract: 996,409. Telegraphy; multiplex pulse code signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1963 [Dec. 18, 1962], No. 45925/63. Drawings to Specification. Headings H4L and H4P. In a data receiver to counteract drift in the clamping circuit that occurs when the data has one value for some time a D.C. feed-back path is provided from the output of the receiver to the input. In the embodiment described two binary messages are transmitted as a single 4-level message by adding one to the other doubled in amplitude. This message is preceded by a signal which causes a clamp in the receiver to place the received data at the correct level. The data is fed to threshold circuits which provide three signals indicative of the level of the data. These signals are fed to logic circuitry to derive output signals the equivalent of the original two binary messages. The outputs from the logic are combined to give a four-level signal which acts in the D.C. feed-back loop to stabilize the D.C. level at the receiver input.

Abstract: 1531759 Electrochemical filters SIEMENS AG 6 Nov 1975 [8 Nov 1974] 45986/75 Heading H3U An electrochemical filter comprises parallel rodshaped resonators R1-R10 which are interconnected by at least one coupling wire LK, the input and output transducers EM being connected to resonators other than the end resonators, those resonators outside the signal path between the transducers providing attenuation poles in the transmission characteristic of the filter. The resonators are supported at nodal points by wires S welded thereto and mounted in grooves in base G, which is either of metal or synthetic resin. As shown, the resonators are bending oscillators and electrostrictive transducers are mounted on flat faces of resonators R2, R9; the other resonators also have flat faces by which they are coupled to wire LK. In a modification resonators R2, R9 each have a portion with a second flat face perpendicular to the first one and for coupling them to wire LK. Each transducer is connected to a respective coil, which together with the self-capacitance of the transducer forms a resonant circuit tuned to the centre of the filter pass band but with a greater band width.  The position of the poles introduced by resonators such as Rl, R10 may be displaced by varying the masses of these resonators or the length or thickness of the adjacent part of wire LK. Further poles may be provided by coupling wires UK which bridge over one or more intermediate resonators. The resonators may be torsional oscillators in which case they may be supported by wires HD, Fig. 7, attached to projections A of base Gl; alternatively they may each be supported by a single respective wire connected between a node and the base (Fig. 5, not shown) or all the resonators may be supported by two common wires HD mounted in chips (SH, Fig. 6; not shown) extending from the base. In each case the resonators are coupled by a wire KD.
