Abstract: 1,270,570. Clamps. SMITH-BLAIR Inc. 12 Nov., 1969, No. 55277/69. Heading E2B. [Also in Division F2] A pipe clamp comprises a flexible sheet metal band 14 adapted to extend about a pipe, a pair of rigid lugs 18 fixed to respective end portions of the band and each having a base member 20, a boss portion 26 on each base member such portion having a bore 28, a stud 44 having an enlarged central portion of non-circular cross-section which is slidably receivable in said bores and screw threaded end portions projecting from said boss portions when said central portion is received in said bores, and a nut 49 threaded on each said end portion, said central portion being elongated as seen in cross-section in the direction away from said base member, the arrangement being such that when the sheet metal band is disposed about the pipe with the boss portions spaced from one another and said central portion received in said bores, the band can be tightened about the pipe by screwing the nuts towards one another. In the construction shown the base member of each lug has a pair of jaw portions which can be closed together to grip the respective end portion of the band and the bore through the boss portion extends through the upper jaw portion. The central portion of the bolt or stud has a cross section which is either oblong with parallel sides and semi-circular ends or alternatively it can consist of two circles which touch each other formed by welding two circular section members together. As shown the bore is non- circular and extends completely through each boss portion and two nuts bear on washers 36. Each washer has an angled end portion which bears on an inclined surface of the boss portion to prevent the washer rotating. In an alternative construction in which each boss portion has a circular exit hole through which the end potion of the stud passes the nut engaging the boss portion directly.

Abstract: 1284242 Valves METZENAUER & JUNG GmbH 20 Nov 1970 [22 Nov 1969] 55349/70 Heading F2V [Also in Division H1] A time delay device has an adjustable air inlet valve 50 and a release valve 59. When restraint means, not shown, is removed to permit a spring 64 to move a rod including member 61 downward its rate of movement is dependant on the flow of air into the bellows 45 through the passages 56, filter diaphragm 55, passage 54, valve 50 and passage 58. The valve 50 has a spring biased taper pin 51 passing through a seat 52 to an extent determined by the position of an adjustable screw 57. The screw 57 has a toothed part 67 engaging with a rotatable head 68 indexed to indicate the valve aperture. The lower end of the bellows is weighted to increase its inertia so that when the rod is moved upward its member 61 leaves its bellows seating 60 and permits air to escape until a spring 62 recloses this valve 59.

Abstract: 1449472 Compression moulding thermoplastic articles OWENS-CORNING FIBERGLAS CORP 7 Dec 1973 [29 Dec 1972] 56906/73 Heading B5A A method of moulding fibre reinforced thermoplastic articles comprises the steps of (a) heating a mass of thermoplastic polymer having fibres distributed therethrough to a temperature, above the melting point of the polymer, at which the viscosity of the mass is such that it will retain its shape unless subjected to a compressive force, (b) introducing the mass into a compression mould, (c) closing the compression mould on the mass at such a speed and with such a force that the mass flows and fills out the mould cavity before there is significant heat transfer to the mould, (d) maintaining the compressive force until the moulded mass is sufficiently cooled to be handleable, and (e) removing the compression moulding forces and  removing the article from the mould. Preferably the heating takes place in a screw extruder in which the polymer and fibres are compounded. The heated mass is extruded and cut into billets which are then fed to the compression moulding apparatus which may be, for example, a mechanical stamping press. Polymers which may be used are polyethylene, polypropylene, nylon, thermoplastic polyester, polyvinyl chloride. The fibrous reinforcement may be milled fibres, boron fibres, asbestos fibres or glass fibres, and a filler such as talc, calcium carbonate or silica may be used.

Title: Automatic electric egg cooker
IPC: H05B1/02
Filed: 1966-12-20
Abstract: 1,120,749. Egg-cooking apparatus. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 20 Dec., 1966 [29 Dec., 1965], No. 57008/66. Heading A4D. An egg cooking device comprises a boiling pot 1, accommodating eggs 59 and water, an electrical heating element 2 controlled by a thermostatic switch, a water tank 4 for holding cooling water for cooling the hot eggs and a cooling water injection valve 30 and 50 adapted to be opened and closed by making use of a change in the magnetic characteristics of a ferrite 5 having a Curie point lower than the operating temperature of the thermoplastic switch. In operation the stand 58 with the eggs 57 are placed in the pot 1 together with a measured amount of water appropriate for hard or soft boiled eggs. The tank 4 is filled with water, mounted in pot 1 with the legs 45 engaging the peripheral wall surface of the central raised portion j of the pot so that the magnets 6 and 54 are aligned axially and then the cover 3 is fitted. The operating end 29 of the lever 15 is moved upwards, causing the magnet 19 to be attracted by the ferrite 9 and simultaneously the by-pass plate 21 is carried upwards on the lever to shield the flux of the magnet 6 and the contact 37 is closed by the upward movement of the insulator 38. The heater is energized, steam rises past the eggs and escapes through vents c and n in cover 3. When all the water has evaporated, the pot heats up rapidly and when the ferrite 9 is heated above its Curie point, about 115C., it loses its magnetic characteristics causing the magnet 19 to move downwards by the bias of the spring 20, causing the lever 15 to swing down about the pin 16. The movable contact strip 26 is depressed by the insulator 38 placing the contact 37 into the open position thus de-energizing the heater and allowing the by-pass plate 21 to move down simultaneously. At the same time the magnet 54 is moved upwards by a repulsive force acting between it and the magnet 6, since the ferrite 5 is heated at a temperature above its Curie point, about 60C. Consequently the valve rod 49 is also moved upwards opening the valve element 50, alowing the cold water to flow from tank 4 through the valve port 30 and the spaces between the fins 47 of the valve seat body 46 into the magnet cover 56 and then through the holes 55 and the spaces e into the pot 1 where it cools the hot eggs. A heat-shielding element 57 is provided to delay the premature cooling of the ferrite 5 and when cooled below 60C. the latter regains its magnetic characteristics, the magnets 54 and 6 attract each other and then the valve port 30 is again closed by the valve element 50. The valve seat portion i is preferably formed of a resilient material, such as rubber, so as to obtain uninterrupted engagement between the valve element 50 and the valve seat portion i.
