Abstract: 1372437 Moulding buildings; gripping tools UNICO Inc 14 Aug 1972 37794/72 Headings B5A and B4W [Also in Divisions E1-E2 and H2] A building (see Divisions E1-E2) is formed as an integral unit from a synthetic material such as polyurethane foam, between inner and outer mould portions 30, 40, 46 (Fig. 5), the plumbing, electrical circuitry, door and window frames &c. being positioned in the mould before moulding. The inner mould portion 30 defining adjoining rooms is positioned by hydraulic jacks 38 adjacent a floor 39. A baseplate 134 (Fig. 12), interior door frames, elec- 'trical circuitry, plumbing, air conditioning conduits &c., are located on the inner mould portion 30 adjacent apertures through the mould walls. The outer mould 40, moving on rails 45, roof mould 46, window and exterior door frames are positioned, and the mould portions clamped with clamps 60. Polyurethane foam is pumped from a supply 52 (Fig. 5) and air evacuated from the mould (not further disclosed) and after curing, the mould is dismantled and the building transported on the base-plate 134 (Fig. 12) by helicopter for spraying and decorating. The outer mould portions are contoured te give the building the appearance of wood or aluminium cladding, bricks or stone. Mould clamps.-The mould clamps 60 (Fig. 12) are pivoted at 62 to the outer mould portions 40 and a pivoted clamp head 69 engages an inner mould shoulder 30a. A handle 66 turns a screwed shaft to clamp the head 69, which is released by pivoting with handle 72. Positioning inserts.-Frames &c. are located by guns 80 (Fig. 12) engaging the mould. A rod 94 (Fig. 10) when moved to the right and rotated retracts and holds latches 87 within a barrel 84, which is then inserted through the mould wall to engage the frame &c. with the released latches 87. A trigger 105 moves a ratchet 108 engaging teeth 111 on the barrel 84, to move the barrel to the right and clamp the frame. After moulding, a lever 114 releases the ratchet teeth 111 from a retaining dog 116, to free the barrel 84 for movement to the left, and then removal from the frame and mould.  Inserts.-Air conditioning units are embedded, and comprise preassembled central control unit, conduits and thermostat (see Figs. 14, 15 not shown). A preassembled electrical system (see Division H2) of control box, terminals and conduits is used (see Figs. 16-19, not shown). Plumbing, window and door frames (see Divisions E1-E2) are embedded. Tongs.-A pair of tongs for handling the inserts comprises grippers 256 (Fig. 21) pivoted at 257 to a rod 255 spring-urged upwardly within a barrel 254. A handle 261 pivoted to a fixed extension 260 of the barrel 254 retracts or projects the grippers 256 from the barrel, the grippers being pivoted closed by camming surfaces 258, 259.

Title: Mechanical plating apparatus and method
IPC: C23C24/04
Filed: 1964-09-17
Abstract: Articles are plated by placing them together with small particles of a plating metal, e.g. Zn, in a drum 120 which is rotated and vibrated or reciprocated axially by eccentric weights. The drum is charged by a loading bucket 180 and after plating, the drum is pivoted anti-clockwise to transfer the articles to an after treatment drum 230, where the articles are separated from excess plating metal. Steam and water may be supplied through jets 216, and hot air through ducts 214.  Alternatively the articles may be subjected to a further treatment e.g. chromating by using the shell 230 as a container and allowing the treating liquid to pass through the perforation in the drum 230.  Baffles 221, 222 are provided in the drum 230 and are so shaped that when the drum is rotated in one direction it acts as a tumbling drum, but when it is rotated in the other direction the articles are screwed to the discharge end of the drum having a chute 250.  The periphery of the drum has alternate perforate and imperforate panels.  The drum 120 may be lined with Neoprene, and is supported by steel or glass fibre-resin springs 135.  The same apparatus may be used for cleaning the articles to be plated. <PICT:1085702/C6-C7/1> <PICT:1085702/C6-C7/2>

Filed: 1959-11-10
Abstract: 880,823. Engine-control systems. THOMPSON, R., and WOOLDRIDGE Inc. Nov. 10, 1959 [Jan. 19, 1959; April 15, 1959], No. 38134/59. Class 40 (1). [Also in Group XXVII] In an internal-combustion engine in which additional air is added to the exhaust gases for effecting combustion of unburnt components of the exhaust gases in an afterburner, the supply of additional air is controlled in accordance with the flow through the engine and with the equivalence ratio (i.e. the actual fuel-air ratio divided into the stoichiometrically correct ratio) of the mixture fed to the engine to cause the overall equivalence ratio of the air and exhaust gases fed to the afterburner to be slightly below unity, i.e. to provide a slight excess of air in the bases in the afterburner. In Fig. 9 the air flow rate through the engine is indicated by a three-dimensional cam 120 moved axially according to throttle position and angularly according to engine speed, a cam follower 124 adjusting a member 132 to give a signal on a potentiometer 127 in accordance with engine throughput. A flow-meter 134 in the petrol supply pipe gives a second signal on a device 135, the two signals being compared in a device A to produce a difference signal in a coil 154, representing the amount of additional air required to give the desired overall equivalency ratio, which signal controls an electric motor 150 driving the additional air pump 142 feeding air into the exhaust gases flowing to the after-burner 12.

Title: Diversity receiving system
IPC: H04B7/08
Filed: 1973-08-13
Abstract: 1399190 Diversity reception LICENTIA PATENT-VERWALTUNGS-GmbH 13 Aug 1973 [23 Aug 1972] 38139/73 Heading H4L A diversity reception system comprises means to combine the received signals and means for comparing the signals prior to combining and where the phase difference between them exceeds a specified value, for utilizing only that one of the signals having the best signal-to-noise ratio or whose level corresponds closest to a specific pilot level, and no other received signal or combination of signals is utilized unless or until the phase difference falls below the specified value. As shown in Fig. 1, the received base band signals at A and B are supplied directly to a combiner 2 and via branching circuits 3 to a phase comparator 7. The signal from A is frequencychanged at 4 and supplied via a switch 5 to a noise evaluator 6 which controls the combiner 2 and the signal from B is supplied via switch 5 to the noise evaluator. The phases of two discrete frequencies, e.g. a pilot signal, from the base bands are compared at 7 and if the difference exceeds the specified value, a logic circuit 8 controls the combiner 2 so that it amplifies only that base band which has the best signalto-noise ratio and it is not switched over to accept also the other base band until the phase difference falls below the given value. The arrangement avoids phase jumps which thereby cause amplitude distortions which are particularly detrimental to T.V. transmissions.
