Patent GB-1299990-A (GB)
Title: Self-luminous light-source and assembly thereof
Inventor: HAND ALBERT
IPC: F21S8/00
Filed: 1970-12-07
Abstract: 1299990 Uses of luminescence BRANDHURST CO Ltd 7 Dec 1970 58036/70 Heading C4S  A light source consists of a sealed glass tube internally coated with phosphor (e.g. ZnS) containing a radio nucleide (e.g. tritium) to excite the phosphor, and having one or more transparent synthetic polymeric collars 2 serving as locating members in an eventual assembly but leaving the major portion of the tube length uncovered, the tube extending completely through the central hole in the or each collar. The tube may be arcuate and shaped as a letter (e.g. Fig. 4, not shown) or as a digit. The tube may be within internally smooth and reflective annular channel 3 and in a straight instrument dial or telephone dial, and a tube or tubes may extend along an approximate optical centre, the groove being semicircular, a true optical centre being applied to a parabolic section. Straight instrument dials or illuminated signs with light sources defining letters or digits are mentioned. In Fig. 4 (not shown), the collar is distorted at (5) and (6) to be mechanically held without adhesives, the cover (4) with frosted surface (7) ensuring protection against breakage and loss of radioactive material. The above construction also reduces the probability of cracking due to thermal expansion differences. One or more sources may be held by a cover in a channel, usually metal or plastic, and made reflective by metallizing or painting. A diffusing screen or instrument dial may have a frosted backing and the use of collars reduce the risk of the frosted material irregularities becoming partially filled with synthetic material. Safety sign applications are also instanced.

Patent GB-1170270-A (GB)
Title: Improvements in or relating to Drive Assemblies.
IPC: F16H61/42
Filed: 1966-12-29
Abstract: 1,170,270. Hydrostatic transmission control. LINDE A.G. 29 Dec., 1966 [31 Dec., 1965], No. 58110/66. Heading F2D. An override control for a continuously variable speed gear which prevents overspeeding of an input and/or output shaft comprises means sensing overspeeding or a condition which would cause overspeeding and preventing ratio shifts in a direction to increase the overspeeding. As shown in a motor vehicle transmission wherein an engine 13 drives the wheels through a hydrostatic transmission having a variable displacement pump 15, 16 under the control of a lever 18, excessive engine speed during overrun is prevented by a spring-pressed plunger 21 which overrides the normal control and reduces the pump displacement to zero when the engine speed exceeds a predetermined value and the pressure in the return line to the pump exceeds a predetermined value. The plunger 21 is normally held in the position shown by a pin 27 engaging a groove 26 in the plunger. The pin 27 is acted upon by pressure in the return line and by an input driven centrifugal governor 28 so that when both exceed predetermined values the pin 27 is withdrawn and the plunger 21 moved right by a spring 24. The V-shaped end 20 of the plunger engages a pin 19 on a link 17 between the lever 18 and pump 16 to move the latter to its zero displacement position. In Fig. 1 (not shown), an engine (1) drives a fixed displacement pump (3) supplying pressure liquid to a variable displacement motor (4) driving an alternator (2). The motor displacement is normally varied by a lever (5). In the event of failure of the electric circuit supplied by the alternator a solenoid (12) is de-energized to release a pawl (9) which is pressed by a spring (10) into engagement with a ratchet (8) fast with the lever (5) and thus prevents further movement of the lever (5) in a direction which reduces motor displacement and increases output speed. Excessive speed of the unloaded alternator is thus prevented.

The tool bit holder 31 is movable relative to tool casing 1, and means is provided for retaining the tool bit holder in an inoperative position when the tool is operating under "no-load" condition. As illustrated the cylinder which is reciprocable by a motor via a crank arrangement effects reciprocation of the piston via two air cushions formed between the piston and cylinder, and the means comprises an annular groove 35 on a splined portion 29 of the holder and a resilient ring 36 located between a washer 20 and a bearing bush 24. The holder is shown in its inoperative position. A tool bit having a hexagonal shank for engaging in a hexagonal bore 34 of the holder and an oppropriate recess for receiving a retaining pin 16 is introduced into the holder. The tool is then pressed against a workpiece, the ring is forced outwardly of the groove 35 and the holder moves to an operative position. An internally splined continuously rotatable member 26 receives the splined portion 29 of the holder so that during operation rotation is applied to the tool bit. The ring may be a closed rubber ring or a split ring of steel or plastics material and may be of circular or oval cross-section. Alternatively a spring loaded ball may be provided to extend into the groove 35.
