Abstract: 1,018,727. Retractive switches. MACKWORTH G. REES DIVISION OF AVIS INDUSTRIAL CORPORATION. March 5, 1963 [March 12, 1962], No. 8653/63. Heading H2B. In a push-pull device for actuating two switches 21, 22 and containing a transformer 19 for supplying a lamp 45 in a translucent pushpull knob 38, switch 21 is normally open and switch 22 is normally closed when the knob is in its central inoperative position. The contacts of switch 21 close when the knob is pulled outwardly, thus energizing a relay coil, which closes a pair of contacts in the circuit, and lights the lamp. When the knob returns, by springs 34, the switch 21 opens, but a shunt bridging switches 21, 22 keeps the lamp alight. When the knob is pressed, switch 22 opens, breaking the circuit to the lamps, and the knob is returned to its inoperative position by a spring 35. An element 23, engaged by a washer 24 connected to a member 26, attached to the knob, actuates switch 21. Washers 14, 39 and an " O " ring 40 seal the device against dust, liquid &c. The device may be mounted on a panel 11.

Title: Mouldings from highly polymeric linear esters
IPC: B29B13/00
Filed: 1946-03-22
Abstract: Sliding-clasp fasteners, bottle closures, picnic ware, small bobbins for the textile industry, handles for kettles and for electric irons, electrical switch covers, control knobs and terminal blocks, bearings, and shapes suitable for the cold pressing or stamping of metal sheet are made from polymeric linear esters obtained by heating terephthalic acid or an ester-forming derivative thereof with one or more glycols of the series HO(CH2)nOH, where n is an integer greater than 1 but not exceeding 10.ALSO:A molten highly-polymeric linear ester which has been obtained by heating one or more glycols of the series HO(CH2)n OH (where n is an integer greater than 1 but not greater than 10) with terephthalic acid or an ester-forming derivative thereof is forced against a high-melting metal forming surface, preferably stainless steel, and then cooled until it is solid.  The production of the esters is described in Specification 578,079, [Group IV].  Thus, (a) the molten ester may be forced into a closed mould cooled to below the melting-point of the ester, the mould being opened when the ester has solidified.  (b) The ester is placed in a mould having two forces and vertical flashes, external stops being used to produce articles of predetermined thickness. Thick articles may be produced by melting the ester in the mould, which may be heated electrically or by the eutectic mixture of diphenyl and diphenyl oxide.  Thin articles may be produced by pouring molten ester into the cooled mould and, before it has solidified, closing the mould with sufficient pressure to force the ester to its extremities.  (c) Large bubble-free articles are produced by forcing the molten ester into a mould maintained substantially at the melting-point of the ester, small air-escape vents being provided in the mould at points remote from the injection nozzle, and cooling the filled mould, the cooling being started at one or more points so far as possible from the injection nozzle and the pressure on the molten ester from the nozzle being maintained until the mould is cold. (d) A metal moulding surface is pressed against a block of ester, either the surface of the block being molten or the metal surface being heated to a temperature greater than the melting-point of the ester.

Filed: 1936-03-30
Abstract: 459,095. Spray carburetters. GRANVILLE, B., 17, John Street, New York, U.S.A. March 30, 1936, No. 9339. [Class 7 (iii)] A spraying tube extending into the mixing chamber and communicating with a fuel supply, is reciprocated within a stationary nozzle member positioned at the entrance to the mixing chamber and limiting the area of that entrance, by mechanism controlled by the velocity of the air passing through the air intake, the displacement of the spraying tube in the mixing chamber maintaining the proportion of air and fuel substantially constant. The carburetter comprises an air inlet 1 leading to a Venturi 21 and mixing chamber 4, and a fuel chamber 3 containing a float 32 and communicating with a constant level chamber 2 containing a float 8. A stationary tubular member 25 limits the entrance passage to the Venturi 21 and houses a spraying tube 26 mounted on a lever 30 linked at its end to the float 32, the fuel discharged being aerated through an inner pipe 34 in communication with a controlled inlet 41, Fig. 10, through a passage 42. A pitot tube 51, adjustably positioned in the air inlet 1 transmits pressure through a passage 53 and U-tube 58 to the top of the constant level chamber 2 and this pressure, which varies with the velocity of the air in the air inlet, drives fuel into the chamber 3 to raise or lower the float 32, the float keeping the spraying tube 26 at the correct position in the Venturi 21. An adjustable air vent 44 is closed by the float 32 at the top of its lift. Fuel for idling is drawn from the chamber 3 through a vertical passage 77 to a plug 66 formed with two small mixing chambers opening, the one above the other, into the mixing chamber adjacent the throttle valve 6. A projection 78 on the valve blocks the lower opening when the valve 6 is closed, but uncovers it when the valve is opened slightly for fast idling.
