Title: Improvements relating to defect marking apparatus
IPC: G01N29/04
Filed: 1963-04-09
Abstract: 1, 056, 483. Detecting flaws electrically. REPUBLIC STEEL CORPORATION. April 9, 1964 [April 9, 1963], No.30842/66. Divided out of 1,056,482. Heading G1N. [Also in Division H3] Defects in a moving workpiece, such as a wire 18, Fig. 1 (not shown), are detected by a detector 12, and marked by a rotating carbide cutter 21, the detector being connected to a control circuit 13, which generates a series of pulses for intermittently operating the cutter over the duration of a defect. The detector 12 generates a magnetic field, and variations in this field which arise from defects in the wire cause an A. C. signal to pass to the control circuit 13. The control circuit Figs. 3, 4 (not shown) provides an adjustable mark to space ratio for the defect markings, and ensures that this ratio is unaffected by the disappearance of one fault and the rapid appearance of a second fault within a period of one mark or one space. The motor driving the cutter 22, Fig. 2 (not shown), is pivoted, 24, and biased to a retracted position by a spring 25, and the cutter is forced on to the workpiece by a pneumatic valve 14, which tilts the motor in response to each pulse from the control circuit.

Title: Electrical insulator and method of making the same
IPC: H01B19/00
Filed: 1934-10-27
Abstract: A composition suitable for sparking-plug insulation consists of a sintered mass containing at least 30 per cent of alumina, not more than 60 per cent of magnesia, with or without silica up to 25 per cent, the amount of magnesia being at least sufficient to form forsterite with all the silica present, and spinel with any alumina in excess of 40 per cent.  Specified compositions are 12,5 per cent of silica, 36,4 per cent of magnesia, and 51,1 per cent of alumina, corresponding to 30 per cent of forsterite, and 70 per cent of spinel, and 7,5 per cent of silica, 40 per cent of magnesia, and 52,5 per cent of alumina, corresponding to 17,5 per cent of forsterite, 73,1 per cent of spinel, and 9,4 per cent of periclase.  The second of these examples has a higher coefficient of expansion and retains its electrical insulating quality at a higher temperature, but has less mechanical strength than the first.  As raw materials, magnesium carbonate, oxide, hydrate, brucite, talc, serpentine, spinel, rumpfite, iron-free chlorites, and bauxite, diaspore, corundum, fused alumina, silimanite, clay, may be employed.  These may be ground and used raw, or fined or fused, for the body batch.  This is ground, moulded, and sintered.

Title: Improvements in and relating to electric bells, gongs and the like
IPC: G10K1/064
Filed: 1921-11-19
Abstract: 193,159. Lawson, C. G. Nov. 19, 1921. Reciprocating machines.-In an electric bell in which a loose magnetic plunger reciprocates within one or more solenoid windings, the alternate energization and de-energization of the windings are controlled by a rocking member co-operating with pole-pieces mounted at the ends of the windings, the rocking member being in turn controlled by the movement of the plunger which, when passing through a winding, acts as a core therefor and so increases the magnetic flux that the adjacent end of the rocking member is attracted. In one construction, Fig. 1, two windings 6, 7 are provided with end polepieces 3, 4 and a central pole-piece 5 to which is pivoted a magnetic arm 9 under the control of a light biassing spring 13. A plunger 15 moves in a central non-magnetic tube 2 to strike the bell-dome 16. The circuit connections are such that the windings 6, 7 connected in series with the battery are alternately short-circuited at the contacts 12, 11 over a conducting strip 10 and the spring 13, this being effected by the arm 9 which is attracted towards the pole 3 or the pole 4 according as the plunger is centrally within the coil 6 or coil 7. The operating-mechanism is enclosed within a circular box 1 which may have a water-tight cover. In a modification, employing a single winding, the plunger tube is fixed vertically with the winding around its upper portion. A spring-controlled contact arm, pivoted on the lower pole-piece, normally completes the circuit, whereby the plunger is sucked upwards until it is in a position to act as a core for the winding when the arm is rocked to open the circuit and the plunger drops under the action of gravity. In both constructions, the biassing springs may be eliminated by suitably weighting the pivoted arms.

Abstract: 513,353. Step-by-step conveyers. DEHN, F. B. (Smyth Manufacturing Co.). Oct. 26, 1938, No. 30995. [Class 78 (i)] [Also in Group XV] In a machine for finishing the binding of books the latter are conveyed from one finishing station to another in a straight line path by means of carrier jaws 32. As shown, there are six sets of jaws, each set comprising six jaws arranged in opposed pairs, and all the jaws are moved towards and away from each other simultaneously, and are simultaneously reciprocated longitudinally of the machine. Each book is fed upwardly by a plate 31 raised by means of a link 37 which is connected to a lever 38 actuated by a cam on the main shaft 40 and before the plate descends the lower ends of pivoted arms 41 swing beneath the book. The first set of jaws 32 close to grip the book, move it to the initial position of the second set of jaws, and the latter after returning, grip the book and feed it to the initial position of the third set of jaws, and so on. The carrier jaws are mounted for transverse reciprocation on longitudinally-movable carriages 44 supported on fixed bars 45. Slides 46 (not shown) extend beneath all the sets of jaws. and have cam slots therein engaging pins resiliently mounted on the jaws so that when the slides are reciprocated longitudinally in the carriages, transverse reciprocations are imparted to the jaws. The slides 46 are moved relatively to the carriages 44 by means of bell-crank levers which are connected to the slides at one end, and engage with their other ends in elongated slots in horizontal bars which are adapted to be raised and lowered by a system of levers actuated from a cam on the shaft 40. The carriages 44 are reciprocated on the bars 45 by means of levers actuated from a cam on the shaft 40, these levers reciprocating a cross-head mounted to slide on shafts, the crosshead engaging blocks attached to the underside of the carriages. The books travel along a base rail and between side rails.

Title: Improvements in or relating to colour television systems
Inventor: MOTHERSOLE PETER LEONARD
IPC: H04N5/46
Filed: 1956-10-11
Abstract: 832,696. Colour television. MULLARD Ltd. Aug. 15, 1957 [Oct. 11, 1956], No. 31000/56. Class 40 (3). In a television standards conversion system employing a plurality of simultaneous channels at least one of which carries coded signals, i.e. signals arranged in a manner such that they are not directly usable to reproduce the television image, the signals are stored on separate picture tubes or storage tubes for analysis in the desired final standard without decoding. The invention is illustrated in Fig. 1 as applied to the conversion of N.T.S.C. colour signals from 625 to 405 line scanning standards. The original signal is separated by conventional circuits 1, 2, 3, 4, 6, 7 and 8 into its Y, I and Q signals components, and in accordance with the invention these signal components are employed directly to produce monochrome images in respective cathode-ray display tubes 9 10 and 11 without prior conversion to red, green and blue colour component signals. The images are analysed at the 405 line standard by camera tubes 14, 15 and 16 and the resulting Y, I and Q signals converted back into N.T.S.C. form by conventional circuits 20-28. As an alternative to using combinations of cathoderay display and camera tubes, two-gun cathoderay storage tubes may be employed. Clamp pulses generators 13 and 19 are provided to establish the operating levels. in the display and camera tubes at the commencement of each line scan. In the case of display and camera tubes for the I and Q signals the operating level is chosen in each case to occur at an intermediate point on the tube characteristic, Fig. 2 (not shown), since the signals are not unidirectional as in the case of the Y signal. Reference is made without given details to a system for also converting the frame scanning standards.
