Title: Improvements in or relating to the protection of electric cables
IPC: H02H7/00
Filed: 1953-02-02
Abstract: 734,436. Protective cut-out arrangements. ETABLISSEMENTS MERLIN & GERIN SOC. ANON. Feb. 2, 1953 [Feb. 1, 1952; March 5, 1952], No. 2873/53. Class 38 (5). A cable, having insulated phase conductors and an insulated pilot wire which are associated with a safety screen having a metallic leakage collector, is protected against screen to pilot wire faults by connecting the pilot wire and leakage collector to opposite poles of a condenser. The invention is described as applied to the cable of Specification 716,516 which has power conductors a, b, c, an earthing wire and a pilot wire 1, the latter having a coaxial leakage collector 2 connected to a conductive screen 5 in which all the conductors are embedded. If a fault occurs between the collector 2 (i.e. the screen 5) and the pilot 1, the following circuit is made: collector 2, conductor 62, relay coil 20, negative terminal of a condenser 60, the positive terminal thereof, earth, a rectifier 17 and pilot 1. The coil 20 is thereby energized to open contacts 21 and close contacts 22, thereby de-energizing a relay 13, the contactor coil 12 and an indicator lamp 54. The relay 13 is connected across a condenser 14 in the pilot circuit 1 and is normally traversed by a low rectified A.C. derived from a transformer 19, but if a pilot-to-earth fault occurs, e.g. at A, the rectifier 17 and a resistance 18 are shortcircuited so as to pass a greater current through a rectifier bridge 53 to relay coil 20 which is thereby energized. The positive side S of rectifier 53 is connected to earth through a circuit 57, 58 and a parallel circuit containing a neon lamp 56 and rectifier 55. The negative side t of rectifier 53 is connected to earth over the condenser 60 and a resistance 61. Faults from phase to screen or screen to earth also complete circuits including condenser 60 and coil 20. If, after a plug 68 is removed, a fault occurs between conductors 1, 62 (which are normally connected to the pilot and screen), A.C. flows through the transformer 51 and conductor 65 to earth, via point s and circuit 57, 58 so that coil 20 is energized.

Abstract: 940,888. Making threaded spindles or tubes; coiling; soldering. RHEINMETALL G.m.b.H. Jan. 26, 1961, No. 3110/61. Headings B3A, B3E and B3R. A method of making threaded spindles, e.g. for jacks, comprises coiling into a spiral a strip of metal which is preformed with a longitudinal rib in such a manner that when the strip is coiled the rib constitutes a screw-thread and the remainder of the width of the strip overlaps at least one adjacent turn of the thread in the finished spiral. Steel strip 1 having a flat portion 3 and a raised rib 2 formed by stamping, rolling or pressing passes through a tinning bath and is coiled into tubular form by a heated member 4 which also serves to melt the tinned coating. The strip may be lubricated with graphite or molybdenum disulphide after tinning. The coiled strip then passes to a cooling member 5 which causes the solder to cool and set. In another embodiment, Fig. 3, additional ribs 6, 7 are formed in the strip before coiling to support the threads 2. Alternatively, Fig. 4, rolled beads 8 and reinforcements 9 are formed in the strip prior to coiling or, Fig. 5, reinforcements 11.

Abstract: 1,012,936. Automatic volume control circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 24, 1964 [Jan. 29, 1963], No. 3171/64. Heading H4R. In an adjustable attenuating circuit the signal to be attenuated is combined with an auxiliary carrier signal and fed to a limiter whose limiting potential is set by a control voltage, the output of the limiter feeding a filter from which is derived the attenuated signal, the transmission factor of the circuit being proportional to the control voltage. Fig. 1 shows one embodiment in which the signal to be transmitted is applied to terminals 1 and 2 of transformer 3 to be added, in the secondary of the transformer, to the carrier oscillation from carrier source 10, the carrier being of higher frequency than the signal frequency, spaced by the bandwidth of the signal to be transmitted, and at least four times the amplitude of the signal frequency. The combined signal is fed to the limiter comprising diodes 7 and 8 whose limiting potential is set by the control voltage applied to terminal 4. The limited signal appearing across resistor 12 is passed through filter 13, to remove the carrier frequency and an unwanted sideband generated during the limiting, and the attenuated signal appears across terminals 5 and 6. It is shown in the Specification that the transmission factor is directly proportional to the level of the control voltage applied to the junction of the diodes 7 and 8. In a modification, Fig. 3 (not shown), the limiter diodes 7 and 8 are bridged by a second pair of diodes connected oppositely to diodes 7 and 8 and biased by a voltage of equal amplitude but opposite polarity to the voltage applied to diodes 7 and 8. This arrangement is said to be of advantage where dynamic control of attenuation is required, in that the control potential is balanced and does not therefore appear in the output circuit. Fig. 4 shoes a further modification in which the carrier supply is also balanced and this arrangement is stated to simplify the design of filter 13.

Abstract: 1523011 Rotary blow moulding machine start up MONSANTO CO 28 Jan 1976 [29 Jan 1975] 3256/76 Heading B5A A method of starting up a blow moulding machine of the type in which a tube 40 is continuously extruded between the halves 14, 16 of split blow moulds which at the time of receiving the tube are moving in the same direction as the tube, comprises accelerating the moulds to the speed of the tube whilst the tube is deflected out of the path of the moulds, severing the tube when that speed is reached, and then directing the tube along the path of the mould to effect blow moulding. One half 16 of each mould is provided adjacent its pinch edge 100 with a cavity 110 (see Fig. 4) into which material from the tube is compressed during mould closure to form a projecting keeper which retains the blow article mould for easy removal. In the preferred embodiment, in which a pair of tubes 40 are extruded, the rate of extrusion is gradually increased to mould speed whilst the tubes are being deflected out of the path of the moulds over flanged wheels 88, 90, 92. When the mould speed has been reached the spindle of the machine is rotated to bring a probe 82 on a first mould into contact with a first switch LS1 and a probe 84 on a second mould into contact with a second switch LS2. At this point, the machine is started and the moulds accelerate, reaching the design speed matching that of the tube when the first probe engages the second switch. The second switch actuates, through a piston and cylinder device 66, 68 acting through a lever 72 and slider 78, an apertured cutting plate 56 to sever the tube. After the tube has been severed, it no longer passes over the wheels but follows the path of the moulds to facilitate blow moulding.
