Abstract: 834,424. Incandescent lamps. PATENTTREUHAND - GESELLSCHAFT FUR ELEKTRISCHE GLUHLAMPEN. June 6, 1956 [June 16, 1955], No. 17505/56. Class 39(2) In the manufacture of electric incandescent lamps, the filament-supporting leading-in wires 1 and a metal exhaust tube 7 are sealed within the neck 9 of a glass bulb 3 by the application of heat and pressure, and the bulb is exhausted and, if necessary gas-filled by way of the tube 7, whereupon the glass sealing-pinch is subjected to a further heating during which the exhausting tube is' removed while at the same time the lamp is sealed by a second pinching. The operations may be carried out in a rotary turret or a chain conveyer machine provided with suction heads 6 each of which holds a bulb 3 and lowers it upon a mount comprising a filament 2 supported by leading-in 'wires 1 which are held by gripping-tongs 5 and a co-operating central blade 10 provided with a hole 12. Downward movement of the suction head 6 brings the neck 9 of the bulb down on to the gripping tongs 5 and is continued until the upper end of the metal exhaust tube 7 (held by means not shown) is pushed upwardly through the hole 12 in the middle blade 10 and into the bulb. The bulb neck is next subjected to heating by jets from a pair of oppositely disposed burners 8 which are also formed as clamping jaws arranged to be closed automatically, the flames being extinguished during this movement and relighted by igniting flames when the jaws again open. The jaws operate to seal the leading-in wires in position and pinch the glass of the bulb neck around the exhaust tube. The lamp bulb is next exhausted by a vacuum pump connected to the tube 7 and may be filled with gas, after which the burners 8 are relighted to heat and soften the glass seal, the burner flames being directed particularly upon the metal exhaust tube, whereupon the tongs 5 are slowly lifted to withdraw the bulb from the tube and the clamping burners are again pinched upon the bulb neck to seal it hermetically. The exhaust tube is preferably made of copper or a heat-resistant steel, with 'an internal diameter of about 2 mm. and a wall thickness of about 0.5 mm. An initial coating of glass, enamel, or borax which has a lower melting-point than the glass of the lamp bulb, may be provided on the exhaust tube to facilitate its subsequent withdrawal. Separate burners and clamping jaws may be used. For gas-filled bulbs the exhaust tube may be provided with two separate channels through one of which the gas can be blown into the bulb while air and surplus gas escapes through the other. In this manner flashlight lamps containing a combustible material may be filled with oxygen without the necessity for a previous evacuation.

Patent GB-951390-A (GB)
Title: Improvements in an air brake cylinder with a built-in automatic brake slack adjuster
IPC: B61H15/00
Filed: 1962-05-08
Abstract: 951,390. Brake cylinders; brake adjustments. SVENSKA A.B. BROMSREGULATOR. May 8, 1962 [May 19, 1961], No. 17671/62. Headings F2E and F2F. An air brake cylinder with a built in automatic brake slack adjuster has the cylinder front head divided into two parts 4, 24, part 24 being rotatably connected to part 4 which is secured to the front end of the cylinder body 1. The automatic slack adjuster comprises two nuts 10, 11 rotatably engaging a screw-threaded push rod 8 axially displaceable in a tubular brake piston rod 3 secured to the brake piston 2. The nut 10 is housed in the tubular piston rod 3 so as to partake in the movements thereof and transmit the brake power from the rod 3 on to the push rod 8 at braking while the nut 11, by the intermediary of a control member 12 movable together with the piston rod 3 relative to the brake cylinder through a distance equal to a normal brake applying stroke of the piston, on release of the brake limits the return movements of the piston in the rear end position thereof. The piston rod 3 is non-rotatably guided in the rotatable part 24 of the cylinder front head by means of studs 7 engaged in slots 6 so that at released brake it is possible to rotate the part 24 by hand and thereby the piston rod 3 and the nuts 10, 11 on the push rod 8, provided that the latter is non-rotatably connected to the brake rigging operated by the brake cylinder. As shown an abutment ring 9 secured to the piston rod 3 transmits the braking power from the latter to the nut 10 and then to the push rod 8. The control member 12 is provided with studs 17 which project through slots 6 and move between two abutments 18, 19 on the part 24. In operation, if the brake application stroke exceeds the desired value, the coaction of studs 17 with the abutment 18 stops the control sleeve 12 and displaces it together with the nut 11, by means of spring 16, axially of the piston rod 3 and the push rod 8. During the subsequent release of the brake the nut 10 is displaced axially on the push rod 8 by means of the spring 14. Rotation of the nuts 10, 11 is prevented while they contact the ring 9 and sleeve 12 respectively by the friction therebetween: A spring loaded latch 25 locks the parts 24, 4 together. In one modification a superable clutch is provided between the parts 4, 24 the end faces of which constitute the friction clutch faces and are urged against each other at released brake by the brake return spring 5. In another modification the nuts 10, 11 on slack adjustment do not rotate on the push rod 8 but ratch over the threads, so that the push rod acts as a toothed bar and the nuts as pawls.
Patent GB-453185-A (GB)
Title: Improvements in golf balls and their manufacture
IPC: A63B37/08
Filed: 1935-06-20
Abstract: A golf ball is provided with an initially non-gaseous core containing one or more substances which generate gas after the final moulding of the ball.  The core may be formed from a plastic and/or colloidal substance such as stiff clay or a paste rendered permanently plastic by means of water, glycerol or glycol, or such as rubber in which plastifying agents are present.  The gas-generating material, for example, a solution of ammonium nitrite, may be mixed into a plastic core, and the core may be enclosed in an impermeable envelope of gelatine or rubber prior to the application of the usual rubber windings and outer cover.  The degree of stability of the ammonium nitrite solution may be adjusted by the addition of such substances as ammonia, semicarbazide, thiourea, urea, benzoic anhydride or peroxide.  The nitrogen liberated after moulding on the outer cover augments the stress due to the rubber windings and is distributed throughout the core in the form of independent bubbles without impairing the balance of the ball.
