Title: Improvements in photo-electric cells
IPC: H01J40/06
Filed: 1921-03-23
Abstract: 178,301. Case, T. W. March 23, 1921. Vacuum tubes. - A photo-electric cell has an electrode with a coating of light re-active material, such as strontium or other alkaline earth metal, deposited under electron bombardment in the form of fine particles. The electrode is produced by the process described in Specification 178,300. A filament is coated with the oxide of an alkaline earth metal, or with the corresponding nitrate, which may be reduced to the oxide by heating the filament. The coated filament 1 and a metal electrode 2, such as a nickel plate, are mounted in a bulb which is exhausted of air and baked. The metal electrode is heated to redness to drive off remaining gases by means of a discharge between the filament, heated by a battery 3, and the electrode, acting as an anode, for instance, by connecting the electrode and the filament with the secondary of a transformer 4. The temperature of the electrode is then reduced by regulating the potential, and the filament temperature is adjusted so that the discharge causes metal to be emitted from the oxide coating, and to be deposited as a layer on the electrode 2. The tube is connected with a pump so as to maintain the vacuum. The deposition process is stopped at intervals, and the photo-electric qualities are tested. The electrode 2 forms the cathode in the completed cell. An inert gas, such as argon or helium, mav be admitted to the tube to increase the conductivity.

The ends of the tape 11 are formed with holes 12 to which 'T' or crossshaped guide followers (40) (Figs 15 and 4, not shown) are connected by pegs (41a). The guide followers (40) are each slidably mounted in a built-up plastics block (50) (Figs 5 to 8, not shown) having integral resilient hook-like projections (58) by which the block assemblies (50) can be simply snap-fitted to the casings (61, 71) of remotely spaced master (70) and slave (not shown) control units. The master control unit (70) may comprise a manually rotatable knob (74) fast with a scroll cam (75) the groove (76) of which engages a downwardly extending peg (43) of the cross-like follower (40). Alternatively, (Fig. 9, not shown), the rotatable knob (74) is replaced by a manually pivotable lever (96), the peg (43) of the follower (40) engaging a disc (92) of the lever (46). Spring-loaded ball detents (78, 79 or 97, 98) serve to locate and retain the knob (74) or lever (96) in any required setting. Alternatively, the master control unit may be formed as a two position toggle (101) (Fig. 10, not shown) or simply as a spring-loaded, push-button device (303, 304) (Fig. 11, not shown). The upwardly projecting peg 42 of the crosslike follower 40 serves simply to readily engage the downwardly extending peg 43 in its appropriate groove or notch (76, 93, &c.) during initial assembly of the master and slave control units, the latter, i.e. slave control units, of which may be mechanically controlled electrical circuit devices such as variable resistors, variable capacitors, variable inductors and switching circuits in which the slave control elements are linearly movable to engage a contact (83) thereon with one of a number of contacts (85) (Fig. 12, not shown) or are formed as rack-and-pinions for rotationally controlled electrical circuit devices (Fig. 13, not shown).
Patent GB-399198-A (GB)
Title: Improvements relating to the supply of anti-detonating, or other liquids to the fuel supply line of internal combustion engines
IPC: F02M25/14
Filed: 1932-03-29
Abstract: 399,198. Lubricant conveyed by fluid. KIMBALL, L. B., 355, Central Avenue, New Haven, Connecticut, U.S.A. March 29, 1932, No. 9060. [Class 12 (iii).] A lubricating liquid is forced into the supply line fuel or the normal intake of an internal-combustion engine, by the pressure of the exhaust gases, which is transmitted through a pipe 41 to the top of a supply tank 39 and forces the liquid through a pipe 38 to a casing 1 in which are secured members 2, 4. The liquid passes through holes 7 into a chamber above a valve 18, which is carried at one end of a rod 13, the other end having a head 17. The rod 13 passes through a plunger 12, cap 11, and a flexible diaphragm 14 which are urged upwardly by a spring 10 bearing on the cap 11. A tapered valve 22, which controls an orifice 21 in the member 2, is screwed into the valve 18 and the valves 18, 22 are adjusted relatively by rotation of a rod 26 having pin-and-slot engagement at 25 with the valve 22. The valves 18, 22 are depressed by one arm 30 of a bell-crank lever, the other arm 31 of which is connected to the accelerator pedal. When the engine is idling, the valve 18 is closed, and the space above it and the chambers 19, 20 are full of the lubricating liquid. When the engine is accelerated, the arm 30 of the bell-crank lever depresses the rod 13, thus moving the valves 18, 22 and the plunger 12 downwards, and the plunger 12 forces the liquid into the chamber 19, through the orifice 21 into the chamber 20, and through a pipe 42 to the carburetter. The pressure of the exhaust gases then continues to force the liquid into the pipe 42. By rotating the rod 26 the flow of liquid past the valve 22 may be altered, and this enables the apparatus to be used with engines of varying size. The bell-crank lever 30, 31 is mounted on an eccentric 33 which is oscillated by a lever 34 connected through a cable 36 to the dashboard, whereby the amount that the throttle valve can be opened before the liquid is introduced into the main fuel stream may be varied.
