Abstract: 1,147,672. Fuel-injection pumps. ROBERT BOSCH G.m.b.H. -June 1, 1966 [June 1, 1965], No.24412/66. Heading F1A. A combined fuel-injection pump and distributer is regulated by a reciprocating and rotatable shuttle valve 13 controlling a by-pass 14, shuttle 13 being moved on its forward stroke by the delivery of a piston 5 moving in synchronism with the pump piston 4, the return movement of the shuttle by spring 19 being braked by a throttle 25 on the "liquid stop" principle, so that above a predetermined engine speed the by-pass is held open. Excess fuel for starting and adjustment of the regulation according to load is provided by a control edge 18 on shuttle 13. Edge 18 co-operates with by-pass port 39 according to the angular setting of the shuttle by an automatic control comprising a piston 32 subjected to the delivery pressure of a feed pump 7 which is dependent on engine speed. Movement of piston 32 is controlled by a series of springs, Fig.5 (not shown), which are effective at various engine speeds to provide excess fuel for starting, and fuel for normal running without smoke emission. The spring- loading is adjusted by a lever (49) to set the engine speed up to the predetermined speed at which the "liquid stop" operates. In another embodiment, the "liquid stop" is used throughout the engine speed range by adjusting the throttle 25 by linkage 49a. The engine is stopped by rotating manual control 42 to rotate shuttle 13 to a position in which by-pass 39 is open continuously.

Abstract: 789,595. Counting-apparatus. UNITED GAS INDUSTRIES, Ltd. Aug. 22, 1955 [Aug. 23, 1954], No. 24465/54. Class 106 (1). In indicating or registering mechanism for gas and like meters the drive from the metering mechanism to the usual index driving spindle is transmitted to the planet carrier of an epicyclic gearing of which the respective sun wheels each effect rotation of a corresponding toothed wheel, one or both of the said toothed wheels being connected to the driving element of an index or counter mechanism and being selectively operable, the selection of the toothed wheel to be operated at any moment being effected under the control of a timing mechanism, which operates a trip device to immobilize the toothed wheel that is not required to operate. The shaft 5, Fig. 4, is driven from the meter and carries a differential gear comprising sun wheels 7, 9 and planet pinions 11, 12. A counter drive spindle 18 is connected by gearing 13, 16 to the sun wheel 7 and a counter drive spindle 19 is connected by gearing 14, 17 to the sun wheel 9. Below the gears 13, 14, 16 and 17 is a pivoted bar 22, Fig. 3, which carries two spring fingers 26, 27 and which is controlled by a star wheel 29 so as to assume either of two positions in which one of the counter gear trains is locked by the finger 26 or 27. The star wheel 29 is connected to a coaxial ratchet wheel 31, Fig. 7, which is actuated by a spring-pressed pawl 32 carried by one arm of a bell crank lever 34 the other arm of which co-operates with two pins 35, 36 carried respectively by arms adjustably mounted on a spindle of a timing mechanism. The two counters are thus operated alternately for predetermined time intervals. The fingers 26, 27 may be in the form of friction pads which cooperate with friction discs. If only one counter is provided the idle gear train is appropriately loaded. The pivoted bar 22 may co-operate with switches to send impulses to distant meters.

Abstract: 729,432. High-frequency discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 1, 1952 [Oct. 22, 1951], No. 24584/51. [Class 39 (1)] In an electric discharge device of the kind comprising a cavity resonator and a glow discharge tube in combination and having a keep-alive electrode the tip of which is surrounded by a tubular member to form a sheath coaxially spaced about said tip, at least part of said tubular member is conductive over a portion of said member which enters the radiofrequency field to form part of the radiofrequency circuit of the main discharge gap. Fig. 5 shows the invention applied to the type of T.R. cell described in Specification 698,896, in which one main electrode 3 is provided with a tip in the form of a wire loop 2. The keep-alive electrode has a shank 4 made of a nickel, cobalt, iron alloy and a palladium tip 5. The shank 4 is insulated by a glass sheath 9 and a ceramic tube 10 extends around the tip 5. The end and part of the inside of the tube 10 are covered with a layer of metal 11. In an alternative construction, the ceramic tube 10 is replaced by a tubular extension of the glass sheath 9 and the shank 4 of the keep-alive electrode is extended inside the glass tube by a section of reduced diameter, this section being oxidized and having a tip in the form of a palladium tube welded thereto. Fig. 7 shows the invention applied to a keep-alive electrode positioned at the side of a radio-frequency gap 8 between two main electrodes 1. A metal sheath 11 is provided on the glass tube 9 which insulates the electrode 4. In another arrangement, Fig. 8, a metal tube 11 extends into a gap post 3 a distance equal to a quarter wavelength so that it is coupled thereto and itself functions as one pole of the radio frequency circuit and serves to support a wire electrode 2. The Specification refers to the prior practice of making the tip of the keep-alive electrode of tungsten, molybdenum, copper or a nickel, cobalt, iron alloy and providing a space between the tip and a surrounding insulating glass tube. A mixture of argon and water vapour at pressures of 10 mm. and 1 to 4¢ mm. of mercury respectively is described as a typical gas filling in a T.R. cell. Specification 671,414 also is referred to.
