Abstract: A method for determining the position of a mobile radio telephone in a satellite communication system is disclosed. First, a mobile radio telephone scans a plurality of paging channels and measures the signal strength of the paging channels. The mobile radio telephone then selects the paging channel with the strongest signal strength and decodes the information broadcasted on the selected channel. The information contained in the paging channel can include frequencies or timeslots of paging channels in surrounding spot beams. The mobile station then measures the signal strength of paging channels in surrounding spot beams and quantizes the measurements to determine a coarse position of the mobile radio telephone.

Title: A method for the encapsulation of electrical components
Inventor: HOLT THOMAS
IPC: H05K7/00
Filed: 1957-01-10
Abstract: An electrical component is encapsulated with insulating material by coating it with a foamed synthetic resin or with a synthetic resin composition containing a blowing agent and placing it in a mould into which is poured a liquid synthetic resin which has been degassed, and heating the mould and contents to temperatures not exceeding 100 DEG C. to foam the composition if necessary and to solidify and harden the liquid resin to a cured foam-free state.  The synthetic resin composition may be applied to the component with a palette knife and may consist of 50 parts by weight castor oil, 14 parts tolylene di-isocyanate, 5 parts silica filler, and 10 parts azo-di-isobutyronitrile blowing agent. The component is then suspended in a mould into which is poured a mixture of 50 parts castor oil and 14 parts tolylene di-isocyanate degassed by vacuum treatment.  The mould and contents are now allowed to stand until the degassed mixture gels, and are then heated at 95 DEG  to 100 DEG C. to foam the composition, and effect a partial cure which is completed by further heating at 50 DEG  to 60 DEG C. The synthetic resin may alternatively consist of a styrene/polyester or an epoxide resin in which case the composition is foamed before the component is placed in the mould. Specification 749,370 is referred to.

IPC: H01P5/04
Filed: 1954-01-14
Abstract: 791,431. Pulse radar; duplex radio signalling. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 23, 1954 [Jan. 14, 1954], No. 1080/54. Drawings to Specification. Classes 40 (5) and 40 (7). In a pulse radar range-measuring system, very close range operation is effected by maintaining the receiver continuously operative so as to be sensitive to an echo pulse received during the transmission of a transmitted pulse. To prevent interference from the transmitter, the receiver is coupled to the common transmitting and receiving aerial through a known directional coupler, so that energy passing from the transmitter towards the aerial does not appreciably affect the receiver, but incoming reflected signals are passed to the receiver. The short-range system may be combined with a conventional long-range system.
Patent GB-704584-A (GB)
Title: Process of manufacturing reticular gels
IPC: B01J19/06
Filed: 1952-01-14
Abstract: A thin layer of a solution of a polyvinyl formal in a water-miscible solvent is coagulated by treatment with an aqueous coagulant so that the polymer is obtained as a sheet or pellicle of an aqueous gel which is then dried at a temperature not exceeding 35 DEG  C. at normal or reduced pressure.  The dried gel has a reticular structure and it may be readily re-swollen nearly to its original condition by subsequent soaking in an aqueous medium. The reticular gel may be produced in the form of a cover or capsule for a bottle closure.  If desired, the polyvinyl formal may be dissolved in a liquid which is only a solvent when hot, e.g. diethylene glycol, and the coagulation may be effected by adding water at room temperature.  If desired, the water in the freshly formed gel sheet or cap may be displaced by a neutral liquid miscible with water, and then that liquid may be evaporated at low temperature.  The polyvinyl formal covers or caps have a dull appearance when first obtained but they may become transparent after they have been re-swollen, stretched over a support and then dried on the support at low temperature.  If desired white or coloured pigments may be included in the solution of the polymer. When the polyvinyl formal covers are to be used, they are re-swollen by immersion in water or an aqueous liquid which may contain halohydrins, esters of glycols or glycerine, or other substances which enhance the elasticity of the products. Methyl glycol adipate in admixture with glycol diacetate is preferred for this purpose. When the gel is made in the form of a thin sheet it may be used as a dialysis membrane.  Specifications 587,309, 644,790 and 658,166 are referred to.

Title: Improvements in or relating to permanent magnets
IPC: H01F1/08
Filed: 1960-01-12
Abstract: The permanent magnet of Specification 927,289 is made by preparing the Mn-Al alloy so that it includes the required tetragonal constituent and then deforming this constituent by mechanical treatment. Suitable mechanical treatments include rolling, hammering, pressing, extrusion or explosion, but do not include the conventional pressing of the alloy particles merely to provide a coherent compact. The alloy may be mechanically treated in the form of a rod or in the form of particles from which the magnet is subsequently formed by compression, with or without sintering, or with the use of a binder. Alternatively, the particles may be mechanically treated after formation of the magnet body. After deformation the magnet body or particles may be re-annealed at 200-800 DEG C.  The magnet body is preferably enclosed in a jacket during the mechanical treatment.

Title: Improvements in or relating to apparatus for testing aerosol valve units
IPC: G01M3/34
Filed: 1956-01-12
Abstract: 801,370. Testing valves before putting into service. ABPLANALP, R. H. Jan. 12, 1956 [Jan. 21, 1955], No. 1096/56. Class 135. Apparatus for testing the valve units of aerosol dispensers before putting into service, comprises a rotary disc 24, Fig. 2, carrying a number of radial arms 26 pivotally mounted on brackets 25, Fig. 3. Each arm is formed with a cam roller 27 urged into engagement with a fixed cam-plate 21 by a spring 28 and carries a valve unit holder 36 mounting a permanent magnet 37, Fig. 6. Each arm also carries a spring- loaded, bell-crank lever 30 mounting a cam roller 31 engageable fixed with cam-plates 32, 33 on rotation of the disc. Each holder 26 is associated with a spring - loaded plunger 39 engageable on rotation of the disc by a fixed cam 44 to depress the head u<1> of the valve unit U to unseat its valve. Beneath each bracket 26 and carried by the disc 24 is a suction device comprising a pair of tandem cylinders 45, 46 slidably mounting interconnected pistons connected by a lever 53 to a guided arm 55 carrying a cam roller 56 engageable with a fixed cam-plate 19. The cylinder 46 communicates with and carries a head 57 on which the valve unit is held by suction. On clockwise rotation of the disc 24 through worm gearing 7, 8 each arm 26 in turn is raised by the cam 21 and picks up a valve unit by its magnet 37 from a delivery shoot 60. In sequence, an arm is pressed down by a rise in the cam-plate 21 so that the unit carried thereby is pressed against the head 57 and the pistons in the cylinders 45, 46 are moved radially inwards by the cam 19 to supply vacuum to the head 57 to hold the unit thereon. Thence a depression in the cam 21 allows the arm 26 to rise. If the unit leaks it is held by the magnet 37 and carried upwardly by the arm 26, the lever 30 now depressed by the cam 32 dislodging it from the holder 36, the unit being finally swept aside by a kicker 65 driven by a flexible drive 17 and planet gearing 15, 16 into a reject shoot 64. If the unit does not leak it is still held by suction on the head 57 and unaffected by the depressed lever 30. The cam 21 again lowers the arm 26 which passes beneath the cam 44 to depress the plunger 39 to unseat the valve. If the valve opens satisfactorily on the arm 26 again being raised by the cam 21 the vacuum seal is broken and the unit is moved upwards by the magnet to be dislodged from the holder 36 by the lever 30 on being depressed by the cam 33 and finally swept aside by a kicker 67 into a serviceable valve shoot 66. Should the valve fail to open it is later removed from the head 57 by compressed air delivered through a duct 68. Specification 680,067 is referred to.
