Abstract: 1,015,780. Feeding slivers. CASABLANCAS Ltd. Nov. 6, 1964 [Nov.19, 1963], No. 45700/63. Headings DID and DIN. In a ring spinning frame the sliver 5 supplied from cans 6 or other source is carried to a point immediately preceding the intake drafting rollers 3 by a pair of endless conveyer belts 9, 10. The belts are guided by rollers 11, 12, 13, 15, 16 and the rollers 16 are mounted (see Fig. 3) between a forked member 17 which pivots about a shaft 19 and is provided with an upwardly extending handle. When the member 17 is in the position shown in Fig. 3 an idler roller 21 mounted on member 17 bears against the belt 9 and the lower drafting roller 3 so that the belts 9, 10 are frictionally driven at the same forwarding speed as the rollers 3. For threading up the belts the handle of member 17 is depressed against the action of a spring 22 so that the idler 21 bears against a roller 24 driven at a high speed (e.g. at same speed as front rollers 1) and the belts are thus driven at this high speed. The slivers 5 are guided from the cans by flanges 25 arranged in rods 26 running the length of the machine and by sliver guides 27 positioned immediately before the entry to the belts.

Title: Electric bridge circuit for measuring the impedances of inductors

Abstract: 1,204,894. Measuring bridge circuits. A.Y. ESSENSON AND A.A. MORACH. Oct.6, 1967 No.45727/67. Heading G1U. In a transformer ratio arm bridge for measuring impedance components of an inductor 5 carrying a direct current of given value, the two secondary windings 3, 9 of a voltage transformer 1 form parts of the bridge and are respectively connected across an unknown impedance circuit in which the inductor 5 is connected and a standard impedance circuit, the primary, of the voltage transformer being connected to feed the bridge from an A.C. source. The standard impedance circuit incorporates an assembly 13 of a standard inductance 14 and standard resistances 15, 16, 17 switchable at 18 for measuring either series or parallel components of the inductor under test. A variable potentiometer 12 is connected across the secondary 9. A battery 6 supplies the required D.C. to the inductors while the voltage across the unknown impedance circuit is assessed by meter 8. A current transformer 2 has two primaries forming parts of the unknown and standard impedance circuits respectively, and an indicator is connected across the output secondary of this transformer. In operation, the reactive part of the unknown impedance is balanced by adjusting the potentiometer 12, and the resistive part by adjusting either resistance 15, 16 or 17 depending on which is connected in circuit. The arrangement of components within the assembly 13 is set in accordance with the type of impedance 5 being measured, and comprises either resistance 15 in series with inductance 14, or alternatively resistance 16 in parallel with inductance 14 with resistance 17 connected into the transformer winding 11. Balance is observed on an indicator across the secondary of current transformer 2. Resistance 19 and inductance 20 enable the residual reactance of winding 9 to be compensated, while a phase shift circuit 21 enables spurious phase shifts to be compensated.

Title: Method of and system for the protection of objects from  damage or destruction by missiles
IPC: F41H5/007
Filed: 1965-11-03
Abstract: 1421379 Protection against missiles BOLKOW GmbH and R F THOMANEK 3 Nov 1965 [11 Dec 1964] 46640/65 Heading F3A Protection against missiles is afforded by an array 12, Fig. 1, of explosive charges which is detonated automatically so as to destroy or deflect a missile. The charges, which are hollow and therefore directive, are laid in a matrix over the surface to be protected and are mounted to direct their force towards the missile and away from the surface. The missile 16 is detected by one or more receivers 14 towards which light (visible or invisible) rays are sent by sources 14. To avoid unwanted charge detonation it may be arranged that only a ray-intercepting object above a predetermined speed effects detonation. An explosive charge Fig. 3 may consist of an explosive 31, lining 32 and detonator 33 in a casing 34 comprising a thin sheath 35 for weather protection and a thick casing 36 not disrupted when the charge is detonated. A matrix form of charges is described Fig. 2 (not shown) for a small object to be protected. The application of the invention to the protection of armoured fighting vehicles, ships &c. is described Figs. 4 to 10 (not shown). In the light ray system the components may be protected against damage, the light rays being deflexed along the necessary paths by prisms or mirrors, Fig. 11 (not shown).

Abstract: 1,187,699. Amplitude modulation. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. 2 Oct., 1968 [19 Oct., 1967], No. 46687/68. Heading H3R. A self balancing carrier modulator comprises a first and a second transistor, Ts1 Ts2 respectively, of opposite conductivity types, adapted to operate under class B or C conditions, their emitters being coupled together either directly or via first and second resistors R8, R9 respectively. The emitters in the first case and the common point of the resistors in the second are connected to earth via a first capacitor C4, so that the D.C. voltage developed across the capacitor as a result of carrier unbalance in the signals in the emitter circuits automatically acts upon the transistors by modifying their bias conditions so as to eliminate the carrier unbalance. The transistors obtain base biases from a chain of resistors R4-R7 and are driven with carrier signal from transformer T via D.C. blocking capacitors C1, C2 and series resistors R1, R2 which isolate the transistors, so that a number of such modulators may be driven from one transformer. The modulating signal is fed in to the common point of resistors R5, R6 via blocking capacitor C3, resistor R3 providing a matching impedance. The output into load RL is taken from the two collectors via D.C. blocking capacitors C5, C6. In a modification, which is only suitable for a single modulator, resistors R1, R2 are omitted and transformer T is without a centre-tap (Fig. 2, not shown). In another modification capacitors C5, C6 are omitted and a transformer output provided, two primary windings being shunted across resistors R10, R11 respectively (Fig. 3, not shown).

Abstract: 1,214,325. Laminates. MONSANTO CHEMICALS Ltd. 13 Jan., 1969 [13 Oct., 1967], No. 46860/67. Heading B5N. [Also in Division B2] A substrate is extrusion coated with a layer of a copolymer of an olefinic hydrocarbon and an aliphatic non-hydrocarbon monomer, the substrate being subjected to an electric discharge before being brought into contact with an extruded molten copolymer layer which is extruded through a slit die spaced at least one inch from the nip between a pair of rollers into which the discharge treated substrate and the extruded molten copolymer layer are fed, the roller contacting the molten layer being chilled so as to solidify the layer. The hydrocarbon component of the copolymer may be ethylene, propylene. The other component can be acrylonitrile, vinyl chloride, bromide or vinylidene chloride, vinyl acetate or propionate, ethyl acrylate, methyl methacrylate, allyl alcohol or vinyl alcohol. The copolymer can contain three or more copolymerized monomers, e.g. a copolymer of ethylene, vinyl acetate and vinyl alcohol. The substrate may be in the form of a sheet or film, e.g. paper, polypropylene film, polypropylene film coated with a copolymer of vinylidene chloride and vinyl chloride, aluminium foil, cellulose acetate film and polyethylene terephthalate film. The electric discharge can be a spark or spray discharge and is preferably a corona discharge. A discharge with a frequency of at least 1000 cycles per second is preferred. A series of pulses of a relatively high voltage, e.g. 10,000 to 30,000 volts, interspersed by periods of a lower voltage, e.g. not greater than 7000 volts, can be used, the time interval between the pulses being 1 to 20 micro-seconds. From 100 to 2000 Joules of energy are dissipated per square foot of treated surface. The substrate may be moved over a roller past one or more electrodes so that the discharge can take place, the roller conveniently being conducting when the substrate is an electrical insulator or an insulating roller being used when the substrate is an electrical conductor. The chilled roller can be polished to impart a high-gloss surface to the finished coating, or it can be embossed. The coated substrate can be used for wrapping and other packaging purposes, e.g. of food, particularly frozen foodstuffs. A paper that has been extrusion coated with a copolymer of ethylene and vinyl acetate containing carbon-black can be used in packaging lightsensitive photographic materials.
