Title: Dielectric walls for transmission of centimetric radiation
IPC: H01Q1/42
Filed: 1955-09-07
Abstract: Loaded cellular dielectric material used in the construction of dielectric lenses, radomes, and the like (see Group XL (c)) is formed by dusting aluminium particles with powdered magnesium stearate and mixing them thoroughly in alkyd resin.  Toluene di-isocyanate is stirred in until release of carbon dioxide boils the mixture.  It is then poured into a mould and, after setting, cured.  To form a similar material aluminium particles are dispersed in silicone resin and diazoaminobenzine added.  The composition is heat blown and cured.  In a further example silicone rubber paste is loaded with diazoaminobenzene, boric acid and aluminium particles coated with magnesium stearate and the resultant paste thinned with toluene.  The resultant is coated on to a honeycomb support structure and heat applied to foam and cure the silicone compound.  Other loading materials having a high dielectric constant may be used and the cellular material may be laminated with a thin supporting sheet of relatively dense and rigid material such as fibre glass fabric impregnated with benzoyl peroxide catalysed polyester-styrene resin. Specification 815,576, [Group VIII], is referred to.

Abstract: 412,451. Variable speed gearing. FOTTINGER, H., 65, Berliner Strasse, Wilmersdorf, Berlin, KRUCKENBERG, F., and STEDEFELD, C., 16B, Ellernstrasse, Hanover, both in Germany. Sept. 15, 1933, No. 25621. Convention date, Sept. 15, 1932. [Class 80 (ii).] Comprises transmission gearing for railway and other vehicles in which Fottinger hydraulic gear devices connected on the primary side to the engine drive the vehicle axle through trains of toothed gearing alternatively. In the construction shown in Fig. 1 a shaft 11, driven from the engine (not shown) through a jointed shaft, drives a shaft 14 which carries the primary members 15, 18 of two F÷ttinger transformers 15-17 and 18-20, the secondary members 16, 19 being fixed to gear wheels 21, 22 respectively adapted to drive a shaft 25 at different speeds through gears 23, 24. By filling one transformer and emptying the other the shaft 25 can be driven through either gear train. The shaft 25 drives the axle 29 through bevel reversing gearing 26, 27 controlled by a double slidable cone clutch sleeve 30. The gearing is enclosed in a casing 35 having bearings at one end on the axle and suspended at the other end from the vehicle frame by springs or links (not shown).

Title: Grinding apparatus primarily for ligno-cellulose containing material
IPC: B02C7/14
Filed: 1964-06-22
Abstract: 1,066,226. Disc mills. DEFIBRATOR A.B. June 22, 1964 [July 1, 1963], No. 25664/64. Heading B2A. A disc mill, for grinding material containing ligno-cellulose, comprises two rotatable grinding discs 26, 38 arranged in a housing to co-operate with respective stationary grinding discs 22, 24, inlet channels 42, 48 and discharge channels 46, 52 for the material provided in the casing for the pairs of co-operating grinding discs 26, 22 and 38, 24, and concentrically arranged shafts 16, 30 which support the respective rotating discs 26, 38, and are displaceable axially under the action of pressure-fluid actuated servo-motors 60, 62 and 70, 72. As described, two casings 11, 12 and 13, 14 are separated by a part 20 which supports the stationary grinding discs 22, 24. The shaft 16 is mounted in a bearing 18 and the tubular concentric shaft 30 surrounding part of the shaft 16 is carried by a bearing 32. Material to be ground is supplied either in parallel through channels 42, 48 leaving the respective sides of the mill via outlets 46, 52, or the mill may be run in series by providing a pipe coupling to connect together the passages 46 and 48 and discharging via the channel 52. In operation, servo-motor 60, 62 controls only one disc 26. When a pilot valve 80 supplies pressure fluid via a pipe 96 to the chamber 66, the servomotor piston 60 applies pressure via the bearing 18 and shaft 16 to move the disc 26 towards the disc 22; fluid flowing via the pipe 95 into the chamber 68 moves the disc 26 away from the disc 22. Servo-motor 70, 72 controls both discs 26, 38. When a valve 102 supplies fluid via pipes 114, 116, 118 to the chamber 76 of the second servo motor the shaft 16 is displaced to the right and the shaft 30 to the left so that the two discs 26, 38 are pressed towards the respective stationary discs 22, 24. The pressure becomes equalized in the spaces 28, 40 between the respective pairs of discs and the bearing 18 is relieved of thrust. When pressure fluid is supplied to the chamber 78 both rotary discs are separated from the stationary discs. The axial positions of the shafts 16, 30 are adjusted by adjustment of the pistons 82, 82<SP>1</SP> of the valves. The valves 80, 102 are of the kind described in Specification 821,938, and are adjustable by setting screws 100, 1001 which control the supply of pressure fluid to the servo-motors and are free to move within the shafts to protect the apparatus in the event of overpressure.

The gas may be subjected to a preliminary treatment by sprays at 11, 13, and 17 and liquid receiving tanks and recirculating pumps are provided. The casing may be of circular, elliptical or polygonal crosssection and be straight or curved e.g. in the form of a spiral, in a longitudinal direction. As shown, the casing is inclined at 45 degrees but it may be horizontal or vertical, or it may extend along several angles or curves in succession. The direction of the spray nozzles may be against the flow of gas.

Abstract: 1,060,162. Heat shrinking. DIAMOND NATIONAL CORPORATION. June 23, 1964 [Jan. 23, 1964], No. 25914/64. Heading B8C. [Also in Division F4] In a method of heat shrinking a wrapper applied around a flanged receptacle and sealed to form a seam, a portion of the wrapper is selectively shrunk to ensure orientation of the relatively weak seams into a position below the flange before the shrinkage is completed. A filled receptacle T is completely enclosed by a wrapper which has a seam S extending about its periphery and disposed below the flange f of the receptacle. The receptacle is conveyed through the apparatus and is first subjected to hot air from ports 38<SP>1</SP> to shrink the undersurface of the wrapper and maintain the seam in a position below the flange, Fig. 3 (not shown). The wrapper is then heated from above and below from ports 38, 58 to complete the shrinkage. Tension in the wrapper due to shrinkage of the top portion is not transmitted to the seam but is imposed on the relatively rigid receptacle flange, Fig. 4 (not shown).

The first unit comprises square-wave shapers 4, 5 connected to replica impedances 1, 2, 3 so that each shaper is energized by a voltage derived from a line voltage and a voltage dependent on the vector difference between the corresponding line currents. The output of the shaper 4 is differentiated at 7 and the resulting short pulses are supplied to a gate 8 together with the square waves from the shaper 5, a tripping relay 9 being energized when the pulses have the same polarity as the square waves. The three remaining directional units each comprise a square-wave shaper 14, 15 or 16, each supplied via one of the replica impedances 1, 2 or 3 with a voltage dependent on a phase voltage, the corresponding line current and the zero sequence current. Each of these units also comprises a further squarewave shaper 18, 19 or 20 energized by a voltage derived from that positive sequence line voltage which has a phase angle of 90 degrees relative to the particular phase voltage applied to the other shaper of the unit.
