Title: Improvements in or relating to machines for jointing the insulation of cable cores
IPC: B29C48/06
Filed: 1933-12-13
Abstract: 430,091. Insulating cable joints by extrusion - machines. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Malm, F. S. ; 936, Ridgewood Road, Millburn, New York, U.S.A.) Dec. 13, 1933, No. 35130. Convention date, Dec. 29,1932. [Class 87 (ii)] [See also Group XXXVI] For making good the insulation after the jointing of cables, the cable is inserted in clamps 23 and stretched by separating the standard 20 from the fixed standard 19 by the screw-mechanism 21. The supports are then moved laterally on the guides 12 until the cable enters the open side 35, Fig. 2, of an extrusion head, with the joint well clear of the left hand side of the head as viewed in Fig. 1. Perforated tapered dies in mating halves are then placed on the cable between the head and the joint and the cable is then fed axially through the head by rotation of the screw 13<a> either by hand from the crank 14 or by power from the clutch 15 engaged by operating the handle 18. The dies travel with the cable until they wedge in the head, after which the continued movement of the cable draws the joint through the dies. Insulating strip material from the reservoir 24 is masticated by the rollers 25 and then delivered by the tapered feed screw 27 through the tapering valved outlet 28 leading to the extrusion head, thence passing through the orifices in the dies to the cable. Byepass conduits 33 may be opened to allow some of the material to escape to the exterior of the machine in order to equalize the pressure at opposite sides of the dies and to fill all the parts of the machine at starting, before making a joint. The extrusion head is of massive construction with walls approximately equal in thickness to the radius of the die orifice. The casing of the feed screw is electrically heated, and the size of the outlet die is controlled by the sliding members 29 operated by screw-mechanism 30 working in conjunction with a pointer 31 and scale. The subject-matter of Specification 389,874 is disclaimed.

Abstract: 1,204,170. Holograms. TEXAS INSTRUMENTS Inc. Dec.13, 1967 [Feb.20, 1967], No.35357/69. Divided out of 1,204,169. Heading G2J. A method of forming a holgram of an array of point sources of light comprises exposing a recording medium 23 to a reference wave and an object wave once for each point source to be recorded, and varying the relative angles of incidence of the reference wave and the object wave for each exposure whereby the relative difference between the angles of incidence of the reference wave and the object wave for each exposure corresponds to the relative differences in location of the point sources of the array. A beam of monochromatic light from a laser 17 is split at 18, the reference wave being directed on to the recording medium 23 via a mirror 19 and lens system 21, 22. The object wave follows a path determined by mirror 24; lens system 26, 27 and movable mirror 28. The path of the reference wave remains fixed, but for each exposure for a desired point source the mirror 28 is adjusted to vary the relative angle between the object and reference waves incident upon medium 23. The hologram may be used in the production of multiple images from a master image as described in Specification 1,204,169.

Title: An improved process for treating sea weed for manufacturing purposes
IPC: C08B37/12
Filed: 1930-11-24
Abstract: Seaweed is heated with caustic alkali, a tanning agent is added, and the heat treatment continued to produce a gelatinous substance for manufacturing purposes.  To this may be added after drying rubber latex or dried rubber, solid oils, bitumens, &c. The seaweed jelly is always thoroughly dried before mixing with the above materials.  The product may be moulded or dissolved in solvents such as naphtha and applied to fabrics, for example, hospital sheeting.  Fabrics thus treated lend themselves after drying and calendering to embossing, varnishing and other surface treatment.  A small amount of ,880 ammonia may be added in addition to the caustic alkali during the preparation of the seaweed.  In an example one ton of bladder-wrack is boiled in a 1 per cent caustic alkali solution for two hours with stirring, 2-3 gallons of ,880 ammonia are added, and the mixture boiled another hour.  Half a hundred weight of cutch is added and the whole boiled for 5 hours.

Abstract: 898,608. Transferring rod-like articles from one conveyer to another. T.I. (GROUP SERVICES) Ltd. Nov. 5, 1959 [Nov. 5, 1958], No. 35505/58. Class 78 (1). Rods 6 are transferred singly from a bundle of rods on an endless conveyer band 5 by a pair of laterally spaced grippers adapted to grip the rods by rotation thereof, the grippers being carried by a frame 12 which is reciprocated between the full-line gripping position and the chain-line releasing position, in which latter the grippers release each rod on to a rollerway 21 which carries the rods from the grippers. Each gripper consists of a pair of pins 17 projecting from a circular plate 18 which is carried by the frame 12 and rotated by a fluid-pressure cylinder 20 to cause the pins 17 to grip and release a rod 6. The frame 12 is mounted on a shaft 10 journalled between a pair of arms 8 pivotally mounted at 9. A fluid-pressure cylinder 13 acts on a lever 15 secured to the shaft 10 to raise and lower the frame 12, and another cylinder 25 is arranged to swing the arms 8. An adjustably mounted plate 16 is carried by the frame 12 in advance of the grippers. In operation, the rods 6 are advanced up to stops 7 whereupon a switch (not shown) is actuated by the leading rod to initiate a cyclic operation of the cylinders 13 and 20 whereby the grippers grip the leading rod, after which the frame is lifted so that the gripped rod clears stops 7 and then swung to the chain-line position, the grippers are then re-opened to deliver the rod to the rollerway 21, and finally the frame is returned to the full-line position. During the return movement, the plate 16 engages any rods lying on top of the leading rod in the bundle and pushes these back so that the rods are positioned in a single layer adjacent the stops 7.

Title: Improvements in or relating to gas turbine plants
IPC: F02C7/143
Filed: 1932-12-15
Abstract: 410,544. Gas-turbine plant. TENNANT, W. J., 111, Hatton Garden, London.-(Aktiebolaget Milo; 32, Kungsgatan, Stockholm.) Dec. 15, 1932, No. 35579. [Class 110 (iii).] In a gas-turbine plant water or steam is injected into the compressed air which is then passed through a regenerator using the exhaust gases of the turbine before being admitted to the combustion chamber supplying the turbine. Fig. 3 shows the application to a transportable plant. It comprises a double-rotation turbine 1 driving compressors 2, 3 arranged in series, and water and oil pumps 12, 18, and also a double-rotation turbine 4 driving electric generators 5, 6. Air drawn in at 7 is compressed, preferably adiabatically, in the compressors 2, 3, and passes to a cooler 9 into which water from the pump 12 is sprayed. It is then heated in a regenerator 15 by the exhaust gases, and is led to an oil-fired combustion chamber 17 and thence to the turbines by conduits 21, 22. Fig. 5 shows an arrangement suitable for electric ship propulsion. The power turbine 30 drives generators 34, 35, which feed the motor on the propeller shaft, and also primary compressors 70, 36. The compressor 70 is clutched-in only for high speeds, the normal air-inlet damper 43 being then closed. From the compressor 36 the air passes through a sprayer 45, compressors 40, 39, sprayer 49, regenerator 51, combustion chamber 53, turbine 31, (which drives the compressors 39, 40), and finally through a second combustion chamber 57 to the power turbine 30. The exhaust of this turbine is passed through the regenerator 51. The water may be heated or converted into steam in a second regenerator before being injected into the air. In the arrangement shown in Fig. 8, the turbine T drives two water-cooled compressors K<1>, K<2> and a generator H. The cooling water for the compressor K<1> is supplied by a pump P<1>, and a pump P<2> supplies water to the first injection chamber O<1> and also to the cooler X<2> of the compressor K<2>. This water passes through a regenerator R<2> to a second injection chamber O<2> in the air line. This air passes through a regenerator R<1> to the combustion chamber S. Compressed air may be used for starting.

Abstract: 394,030. Jib cranes. BROUGHTON, H. H., 17, Dartmouth Street, Queen Anne's Gate, London, and PRIESTMAN, S. H., Holderness Foundry, Hull. Dec. 24, 1931, No. 35655. [Class 78 (iv).] A safety-indicating device comprises a pointer or other indicator connected to a spring or its equivalent and means for altering the connection in accordance with the angle of the jib, the spring being subject to the tension in the jib-tie or to some other stress due to the load. As shown in Fig. 2, the jib-tie is connected by a link 10 to a lever 16 pivoted on the jib at 18 and bearing on the spring 20 ; or as shown in Fig. 7, the luffing-rope 84 passes round a sheave 86 at the jib-head and is deflected by a sheave 90 mounted on the lever 16. The movement of the lever is transmitted to the indicator, Fig. 3, by a steel cord 24 wound upon the hub 56 of a spring-drum, the cord passing around sheaves 48, 50, Fig. 2, and sheaves 44, 54, Fig. 3. The indicator is mounted on the jib and the sheave 54 is carried on an arm 58 pivoted at 60 and is moved as the angle of the jib varies so as to impress an additional movement on the drum. For this purpose a cam 64 bearing upon the arm 58 is connected by an arm 66 and link 68 to a fixed point on the crane. The lever 16 and the cam 64 are designed in accordance with the various factors which limit the safe load at different radii. The periphery of the indicating drum may be marked with coloured portions indicating safety, caution, and danger, which may be observed against an index on a window 36, and the drum may also carry a brush co-operating with a fixed contact to close the circuit of an electric bell. According to the Provisional Specification, in one form of the invention, the stress in the jib-ties, or a proportion of it, is transmitted to a hydraulic cylinder pivoted on the jib head and connected with a pressure gauge which may itself be a hydraulic cylinder with spring-loaded ram, and the movement of the jib is caused to move a second ram in this cylinder by means of a cam. The two rams may be of the same diameter, and the pressure gauge may be in the cab, the ram carrying a pointer co-operating with a danger mark.

Abstract: 796,892. Power measurement. SIEMENS & HALSKE AKT.-GES. Dec. 13, 1955, No. 35766/55. Class 37. In an amplitude-modulated transmitter, the peak power is measured by deriving a pulse signal at the repetition frequency of the modulation peaks from the high-frequency amplitudemodulated carrier by means of a crystal diode in such manner that the peak amplitude of the pulse signal represents the peak power of the modulated carrier, and deriving therefrom by means of a rectifying thermionic diode a unidirection voltage proportional to the peak power; the device being applicable to measurement of both the forward and the reflected peak powers of the transmitter feeder, utilizing a directional coupler. In Fig. 2, a coaxial feeder 1 connecting a television transmitter output to the aerial is fitted with a directional coupler 2 extending a capacitance plate 8 and inductive loops 9, 10 through an aperture of the outer sheath for coupling to the inner conductor, and the forward and reverse pulsed H.F. components representing modulation peaks which appear across resistors 11, 12 are respectively converted in rectifiers 17, 18 to video signals across load resistances 19, 20 representing the forward and reflected powers respectively. These are again rectified by diodes 21, 22 to corresponding unidirectional voltages across load resistances 25, 26 which energize a crossedpointer instrument 33 indicating the forward and reflected powers through D.C. amplifier cathode follower triodes 27, 28 whose anode load circuits are shunted to ground by variable resistances 31, 32 compensating differences in the zero currents of the two diodes.

Abstract: 781,883. Filters. GENERAL ELECTRIC CO., Ltd. Nov. 30, 1955 [Dec. 10, 1954], No. 35837/54. Class 40 (8). A filter having a narrow band stop, e.g. for removing a pilot signal in a carrier telephony system, comprises a band-stop filter 1 arranged in parallel with a complementary band-pass filter 2 so as to form a network having all-pass characteristics, a piezo-electric crystal 15 having a resonant frequency lying within the stop and pass bands being arranged in a shunt arm of the band-pass filter 2. Other resonant frequencies of the crystal lie outside the bands of the two filters. In order to increase the impedance between the points 16, 17 across which the crystal is connected two additional capacitors 18, 19 are included in the band-pass filter to provide impedance transformation. The width of the stop-band may be increased by arranging a number of crystals X1 to X8, Fig. 3, in parallel. The resonant frequencies of the crystals differ slightly from one another, but in order to reduce interaction decoupling resistors R2 to R8 are provided. Fine adjustment of the resonances of the crystals may be provided by variable capacitors C11 to C18 in series with the crystals. The band-pass and band-stop filters of Fig. 3 are derived from those of Fig. 2 by dividing the shunt arms so as to provide two identical L-sections. Resistors R10, R14 are included to correct for the dissipation in the inductors L5, L8. A # network 24 of resistors is inserted between the shunt arms of the bandstop filter to balance the losses in the two complementary filters. Capacitors C1 and C6 provide impedance transformation. For purposes of adjustment the capacitors in the shunt arms of both filters may be made variable or provided with trimmers.
