Title: Improvements in electric discharge lamps
IPC: H01J61/42
Filed: 1935-01-02
Abstract: 427,462. Discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand- Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) Jan. 2, 1935, No. 167. Convention date, Jan. 4, 1934. [Class 39 (i)] In a lamp containing a substance emitting ultra - violet radiation such as mercury, magnesium or cadmium vapour and a rare gas such as neon, argon or helium, a luminescent screen either in or on or outside the valve envelope being caused to fluoresce by the radiation, the vapour pressure of the substance is arranged so low that the negative glow due to the rare gas takes effective part in forming the colour of the light and this glow will have an edging of light due to the discharge through substance, i.e. mercury &c. The required low pressure can be obtained by limiting the operating current or by admitting only a small quantity of mercury &c. to the envelope. The substance to be introduced may be contained in a side tube sealed to the envelope and heated, the vapour diffusing while a discharge takes place. With a luminescent layer of zinc silicate and a mercury and neon filling, the blue edging round the red neon glow will with the green fluorescence give a colour varying between white and yellow depending on the intensity of the blue edging. If calcium tungstate is used instead for the layer, a pinky, violet colour results. Two or more fluorescent materials may be used side by side or mixed together. The luminescent material may be contained in the glass forming the envelope.

Title: Improvements in and in the manufacture of metal castings
IPC: B22D7/00
Filed: 1919-01-03
Abstract: 141,115. Walker, J. B. Jan. 3, 1919. Casting processes.-To prevent piping in steel castings and to allow of the escape of gases during casting, a fusible vent-pipe 3 is partly inserted in the liquid interior of the casting and allows the gases to escape as they rise. The vent-pipe has a charge of thermo-alumini mixture, flour-spar, limestone, &c. at its bottom to intensify the heat of the casting about the vent and increase the fluidity of the metal to facilitate the release of the gases. This charge is released as soon as r the base of the vent-pipe is melted. The pipe may also have a charge of refractory material such as dolomite or slag to assist the escape of the gases.

Title: Improvements in or relating to operating-mechanism particularly applicable to brakes
IPC: B60T7/02
Filed: 1925-01-03
Abstract: 249,932. Edwards, C. K., and Associated Equipment Co., Ltd. Jan. 3, 1025. Hand and other personal actuation; forcetransmitting mechanism. - Force-transmitting mechanism particularly applicable to brakes comprises two operating members, for example a hand and a foot lever, adapted to apply force separately or simultaneously to a single transmission member, a locking device being provided for at least one of the operating members and a resilient link being interposed between this member and the transmission member so that when this operating member has been moved to a selected position, the force applied thereby is not entirely taken off by the application of force to the second operating member. The rod 12 is connected to the brake applying lever 13 and to one arm 23 of a three-armed lever pivoted at 18 to a bracket 17 on the chassis of a vehicle. Another arm 24 of the lever is connected by a slotted link 25 to a pedal 16 and the third arm 28 carries a spring plunger 32 projecting into a slot 29 in which works a pin 30 on a hand lever 19 provided with a detent device 21, 22 for engagement with a fixed rack 20. The hand lever 19 may thus be moved to a position to apply the brake through the spring plunger 32 and be left locked in such position and if it is desired to apply additional force to the brake this may be done by depressing the pedal 16 whereupon lost motion due to the slot 27 is first taken up and the lever 23, 24, 28, turned further in the direction in which it has already been moved by the hand lever. The expansion of the spring 33 maintains contact between the pin 30 and the plunger 32 and thus the application of force from the hand lever to the brake in spite of this further movement of the arm 28. The initial application of force to the brake may be effected by the pedal instead of the hand lever, the slot 29 on the arm 28 moving in this case so as to bring the pin 30 on the handlever towards the end of the slot remote from the spring plungers.
