Patent GB-545956-A (GB)
Abstract: 545,956. Magazine gramophones. INDUSTRIAKTIEBOLAGET LUXOR. July 18, 1941, No. 9104. Convention date, May 28,1940. [Class 40 (ii)] Relates 'to record changing mechanism for gramophones of the kind in which the record discs 5 are piled on a shoulder 4 on a central stem 3 and dropped on the turntable 2 one at a. time by the reciprocation of a member adapted to bear against the edge of the lowermost disc to push it off the shoulder 4. According to the invention, the reciprocating member which in the example shown is a lever 9 is connected to its actuating mechanism 21, 11 through a resilient coupling, spring 12, which enables the member 9 to stop when it has pushed a disc against a stop 6 on the stem 3, while the actuating mechanism 21, 11 can complete its normal full stroke, and means are provided to utilize the variable stroke of the member 9 to determine the starting position of the pick-up according to the size of the disc or the stoppage of the operation when the supply of discs is exhausted. If the lowermost disc is a large diameter one, the member 9 stops before a shoulder 13 thereon reaches a rod 14. If the disc is a small one, the shoulder 13 advances sufficiently to operate the rod 14. And if no disc is present, the shoulder 13 travels farther still and a shoulder 17 on the rod 14 operates another rod 16. The pick-up positioning device (not shown) is normally effective for the large record. When the rod 14 is operated, it carries a rod 15 with it, and this serves to set the pick-up positioning device for the small record. When the rod 16 is operated, it switches the motor off or otherwise causes the machine to stop. If the rod 15 has a limited stroke, a spring 18 is interposed between the rods 14 and 15 to enable the further movement of the rod 14 required to operate the rod 16. The part of the member 9 adapted to engage the discs is formed with a projection 22 which lifts the pile of discs slightly before a shoulder 20 on the member comes to pear on the edge of the lowermost disc. This ensures that the shoulder 20 shall not be engaged by the edge of a large disc just above the bottom disc of small diameter. The record pushed off the shoulder 4 rides down the stem 3 when the member 9 moves away on its return stroke. The pile of discs is held in horizontal position over the shoulder 4 by spring controlled levers 7, 8 bearing on the topmost disc.

Filed: 1972-12-15
Abstract: 1420337 Defrosting AMF Inc 18 Oct 1973 [15 Dec 1972] 58141/72 Heading F4H A defrosting control device comprises an ice sensing device including a series of elements on which frost is to accumulate and which are moved towards each other periodically. When a predetermined amount of ice has formed on the elements, this movement is restricted and causes actuation of a defrost control switch. As shown, a switch-actuating lever 16 is supported on rods 11, 20 and is engaged by a spring 22, a weak, frost-collecting spring 18 and a cam 24 driven by a motor 25. If no defrosting is necessary, on rotation of the cam, the spring 18 collapses and the lever 16 pivots, using the spring 22 as a fulcrum. If frost builds up on the spring 18 to a predetermined thickness, the spring compresses the frost into solid ice and will not collapse, whereupon the cam 24 causes the lever to compress the spring 22 and the lower end of the lever moves a pivoted' arm 26 to actuate a switch 36 controlling the compressor, fan and heater of a refrigerating chamber. The arm 26 is locked in the switch actuating position by a pivoted lever 27 connected to the arm 26 by a spring 32. The lever 27 is released from its locking position by movement of the lever 16 when the frost is removed from the spring 18. In a second embodiment, Fig. 2 (not shown), two members are mounted for linear axial movement on a rod and have interengaging cam faces. The members are urged towards each other by a strong spring and a weak, frostcollecting, spring. One of the members is rotated and, when the frost-collecting spring is coated with ice, is moved axially against the action of the strong spring by relative rotation of the cam faces to actuate the defrost switch. A time-delay may be incorporated to delay switching-on of the fan for a period after the compressor is re-started. The coil spring for frost-collecting may be replaced by discs separated by resilient pads.

Abstract: 1310624 Pneumatic tyres FIVEREL SOC CIVILE D'ETUDES ET DE RECHERCHES 23 Dec 1970 [9 June 1970] 61228/70 Heading B7C [Also in Division D1] A tyre has a carcass including cords each comprising a plurality of glass filaments each of which are enclosed in a sheath of elastomeric material, and having a corrected primary coefficient of twist greater than 90, and a corrected secondary coefficient of twist greater than 130, and an elongation to rupture of less than 3À5%. The tyre may have either a radial ply carcass (5, Fig. 1, not shown), or a discontinuous carcass 5a, 5b having the cords symmetrically interrupted about the median plane of the tyre. In the latter embodiment the tyre may include a substructure comprising a reinforcing ply radially inward of the interruption, and/or a bracing layer beneath the tyre tread. The substructure may consist of a reinforcing ply of rayon and nylon cords, and bracing layer may consist of one or more plies of rayon, nylon or steel cords. For glass filament cords, the formula is given where C is the coefficient of twist, T is the twist in turns per metre and N m  is defined as 1000 divided by linear mass in tex units. Applied to a glass cord of 680 x 3 x 3 d.tex with Z350/S300 twists the formula is said to give a primary coefficient of twist C 1  = 124 and a secondary coefficient of twist C 2  = 183. A method of producing glass cords comprises coating a plurality of glass threads each cbmprising a plurality of continuous filaments with a resin which covers each filament individually, and slightly polymerizing the resin to form an elastomeric sheath about each filament. The threads are then twisted together to form a strand having C 1  greater than 90. Finally several identical strands are twisted together in the opposite sense to form a cord with C 2  greater than 130. Tyres incorporating carcass plies of glass cords may be tested in the following ways:- (a) By rolling against a wheel 1 metre in diameter under a load of 550 kg, the wheel having a protrusion 61 mm. above the periphery and inclined at 45 degrees to the wheel radius, the ambient temperature being maintained at 30 to 32 C. and the tyre being examined periodically until it bursts. (b) By mounting on the rear of a normallyloaded vehicle travelling along a cement track at 35 km./hour, the track having obstructions formed by steel angles 11¢ cm. high at 30 degrees to the track, the number of shocks causing the tyre to burst being measured. (c) By mounting on a vehicle running at an average speed of 100 km./hour for a specific distance on a track with severe bends to cause tyre wear.  (d) By rolling against a wheel as in (a) but without the protrusion, at various loadings to destruction.
