Abstract: 1465955 Moulding silicate-containing polyester HORIZONS RESEARCH Inc 10 April 1974 [26 April 1973] 15965/74 Heading B5A [Also in Division C3] A shaped article comprises a linear polymer, e.g. polyethylene terephthalate, and up to 50% by weight of particles of a solid, acicular silicate nucleating agent distributed uniformly throughout the polymer, the silicate compound having a defined crystal structure. The nucleating agent preferably has a particle size of from 0À1 to 3 microns and is capable of being aligned by magnetic forces thus giving an article oriented in any desired direction. The polymer article may also contain (a) up to 20% by weight of a magnetic sweeping agent, e.g. acicular iron oxide or brass plated iron wires, and (b) up to 20% by weight of a fibrous reinforcing agent, e.g. asbestos. The shaped article may be formed in a mould as shown in Fig. 5 for forming a tubular product, e.g. a tyre, wherein the mould 10 has an inlet 12 and an outlet 13 and the mould is filled from an extrusion die 14 through a port 16. Magnetic lines of force 30 are produced in the polymer by means of an induction coil 22. Fig. 4 shows a mould wherein the desired lines of magnetic force are produced by placing permanent magnets 50 as inserts at appropriate places in the mould wall.

Abstract: 788,928. Hydraulic presses. ELECTRAULIC PRESSES, Ltd. May 28, 1954 [June 12, 1953; July 10, 1953], Nos. 16206/53 and 19156/53. Class 69 (2). In an hydraulic press, supplied with liquid by more than one continuously running pump, a relief valve connected to the press cylinder actuates a selector valve controlling unloading valves so that the pumps are loaded and unloaded according to the pressure in the press cylinder. The selector valve is as described in Specification 727,804 and is actuated by hydraulically-operated pawl-and-ratchet mechanism 1-13, controlled by a solenoid-operated valve 14. The ratchet-wheel carries contact strips BD; BL. When the relief valve closes, it actuates a switch whereby one of two solenoids A, B is energized, the valve 14 moved, and liquid admitted to one of two cylinders 9, 10 whereby one of the pawls moves the disc 1 on the selector valve. When the relief valve opens, the discharge passes through a choke, and backpressure operates a switch which moves the valve 14 in the opposite direction, and the disc 1 is turned in the reverse direction. A hand control can be pre-set to load or unload the pumps when the selector valve has been moved by the pawl-and-ratchet mechanism to the preset position. Micro-switches ME, MF, MH, MG are provided in the electrical circuits operating the solenoids A, B. The switches are engaged by the pawls 2, 3. Two further microswitches are provided and are operated by the pressure-relief valve. The relief valve may be as described in Specification 783,413.

Title: Improvements in and relating to magnetic suspensions
IPC: F16F15/03
Filed: 1942-11-18
Abstract: 559,134. Magnetic suspensions. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 18, 1942, No. 16322. Convention date, Nov. 19, 1941. [Class 37] A magnetic suspension for a vertical shaft comprises two relatively movable-permanent magnet systems, one system comprising a single permanent magnet and the other comprising two permanent magnets axially spaced apart, all the magnets being cylindrical and coaxial. A stationary hollow cylindrical permanent magnet 10, Fig. 1, is mounted with its axis vertical on a non- magnetic support 11, the magnetic axis of the magnet being vertical. A vertical rotary shaft 13 has end portions 14, 15 forming guide bearings with stationary pins 16, 17, which may be resilient. Mounted on the shaft 13 is a pair of cylindrical permanent magnets 19, 20 each having a length approximately one-half of the length of the magnet 10. The lower rotary magnet 19 is magnetized oppositely to the stationary magnet 10 so that its lower end attracts and its upper end repels the lower pole of the magnet 10. The upper rotary magnet 20 is magnetized similarly to the stationary magnet 10, so that its lower pole attracts and its upper pole repels the upper pole of the magnet 10. The distance between the bottom ends of the magnets 19, 20 corresponds to the length of the magnets 10. All the magnetic forces are in a direction to lift or support the weight of the rotary assembly. In a modification Fig. 3, a highly permeable frame 12 extends from the lower end of the stationary permanent magnet 10 to a point above the upper rotary magnet 20, so that some of the flux from the lower south pole of the magnet 10 is brought to the upper part of the frame and attracts the upper north pole of the rotary magnet 20. A highly permeable shaft section 13a is employed between the upper north pole of the magnet 20 and the upper south pole of the magnet 19 and is undercut adjacent to the south pole of the magnet 20 so that this is not magnetically shortcircuited. This arrangement creates a magnetic circuit which is closed except at the working gaps. In another modification the stationary system comprises two cylindrical magnets spaced apart and surrounding a single cylindrical magnet carried by the rotating shaft In other arrangements the inner system is stationary and the outer system rotatable. Specification 550,788 is referred to.

Abstract: 999,313. Manufacturing semi - conductor devices. MULLARD Ltd. May 1, 1962, No. 16646/62. Heading H1K. The invention relates to alloying jigs and to their use in the production of transistors. The single embodiment described is a multiple jig having a substantially rectangular shaped stainless steel body 1 through which extend a number of cylindrical bores 6. Into each of these jewel-tipped steel inserts may be slidably fitted. The lower inserts are retained in their bores by a common retaining plate 17 secured to the body of the jig. In the production of germanium PNP transistors tinned nickel base tabs 22 are placed in the slots 7 of the body with their annular portions 24 within their respective cylindrical bores. The tabs are held in position by a stainless steel wedge 25 itself secured between a V-shaped cavity in the jig body and a series of pins 26 of different height. A circular N-type germanium wafer is placed in each bore and the inserts 8 placed in position. Iridium pellets are tapped into the inserts and alloying carried out in a hydrogen atmosphere at approximately 650‹ C. Each insert rests on the surface of its corresponding wafer, and the inside diameter of its jewelled tip determines the area of alloying. The tinned base tab becomes soldered to the wafer during the alloying process. Inserts 8 are removed and the jig inverted and a second bath of iridium pellets alloyed on. In this case inserts do not touch their wafers and the spread of molten iridium is restricted by the surface adhesion of the globule with the tipped part of the inserts. The joint between base tab and wafer melts during alloying but resolidifies on cooling. After removal of wedge 25 the transistors are taken from the jig, provided with leads secured to the emitter and collector regions, and are mounted in sealed envelopes.
