Title: Metal halide lamps
IPC: H01J61/12
Filed: 1975-11-11
Abstract: 1527899 Gas discharge lamps TOKYO SHIBAURA ELECTRIC CO Ltd 11 Nov 1975 [11 Nov 1974 12 June 1975 1 Oct 1975] 46509/75 Heading H1D In a metal halide lamp containing a rare gas, mercury and a metal halide there is also sealed within the lamp tube elemental boron or a boron compound in an amount in the range of 0À01 to 0À43 microgram-atom per millilitre of the inner volume of the tube which serves to inhibit corrosion of the lamp electrodes by the halogen present and the blackening of the lamp tube. The boron or boron compound is not provided on the main electrodes of the lamp but may be provided on an auxiliary electrode or on a tungsten, niobium, molybdenum or tantalum wire support. Preferably the boron content of the boron compound is not more than 50 atomic per cent. The metal halide of the lamp filling is at least one selected from the group consisting of the iodides, bromides and chlorides of Sn, Na, Tl, In, Al, Dy, Sc, Sm, Cs, Ce and Tm. A number of specific examples of lamps including various quantities of WB, W 2 B 5  and W 2 B are given. Alternatively, the boron may be provided by including in the tube boron iodide, boron bromide or boron chloride in the gaseous phase.

Title: Improvements relating to self-propelled pneumatic hammers for ground burrowing
IPC: E21B4/14
Filed: 1963-11-25
Abstract: 1,026,788. Boring earth, &c. DOM TECHNICZNO-HANDLOWY. Nov. 25, 1963 [Nov. 23, 1962], No. 46534/63. Heading E1F. In pneumatic ground burrowing apparatus comprising a body 1-4 housing a two diameter ram 5 sliding in a guide 6, a chamber 16 is connected to the air supply 31, a chamber 17 is connected to an exhaust chamber 9 through holes 8, and a chamber 18 has groups of holes 10, 11 leading to the exhaust chamber, the holes 10 being controlled by the ram and the holes 11 being controlled by the ram and a slide 12. The apparatus is moved backward in steps when the air supply is at a certain pressure, and is moved forwards in steps when the air supply is at a greater pressure. The front end of the chamber 16 is formed by an anvil 4 which is struck by the ram when the apparatus is moved forwards one step. A buffer 19 forms the rear end of the chamber 18 and is struck by the ram when the apparatus is moved backwards one step. When air at the certain pressure is first supplied to the apparatus a slide 28 covers holes 49 so that air passes to the chamber 16 only to move the ram backwards as there is no pressure in the chamber 18. As pressure builds up in the apparatus the slide 28 uncovers the holes 49 and air flows over a valve-plate 25 to the chamber 18 to move the ram forwards. The pressure drop resulting from the ram uncovering the holes 11 causes the plate 25 to engage its seat 24 to stop air supply to the chamber 18 so that the forward stroke of the ram ends before the anvil is struck. The ram then moves backwards under the pressure in the chamber 16 to strike the buffer and move the apparatus one step backwards. Towards the end of the rearward movement of the ram the holes 11 are covered and pressure builds up in the chamber 18 to cause the plate 25 to move from its seat in readiness for the next forward stroke of the ram. When air at the higher pressure is supplied to the apparatus a plate 33 blocks holes 36 and slides 32, 12 are moved forward by the pressure to close the holes 11 so that the ram moves forward to strike the anvil. As the ram passes the holes 10 the resultant pressure drops in the chamber 18, causes the plate 25 to engage its seat to enable the ram to be pushed backwards by the pressure in the chamber 16. At the end of the rams backward stroke the buffer has not been struck and the valve plate 25 is disengaged from its seat in readiness for the next forward stroke of the ram. In a modification the openings 11 are closed by a resilient inflatable ring connected to the air supply, and the forward end of the ram has a projection engaging a projection on the body to limit the rearward stroke of the ram.

Abstract: 1370623 Testing flash-light apparatus KODAK Ltd 30 Sept 1971 [5 Oct 1970] 47160/70 Heading G2A In the testing of the actuating mechanism of a flash-light device 2 adapted to use percussion ignitable flash-lamp units, which mechanism responds to operation of the shutter release mechanism of a camera 1 assoclated with the device, a predetermined load is applied to a striker releasing member 5 of the mechanism during operation thereof to simulate the resistance of the striker and the movement of the striker releasing member 5 through a predetermined distance while subject to this loading is checked. Testing apparatus 10 is positioned on the camera with a spindle end 12 engaging in the actuating mechanism to set the camera for flash operation and to raise the member 5 into contact with a spring end 21. Actuation of the camera shutter release raises the member 5 and hence the end 21 is raised above a retaining wall 23. The end 21 is thus able to move sideways and operate a micro-switch (26) Fig. 3 (not shown) there being means associated with the apparatus 10 for determining the time between shutter release and micro-switch closure. The micro-switch may be replaced by a light-beam operated photocell. Resetting of the spring end 21 can be effected by a plunger, lever or cam.

[Also in Division F2] In a telescopic suspension element for a vehicle the volume of fluid in one expansible chamber, is controlled to maintain a constant body height by levelling means sensitive to the fluid pressure induced in another expansible chamber in the element by the body load. The hydropneumatic strut 10 shown comprises telescopic tubes 12, 14 each divided into respective gas chambers B, D and liquid chambers A, C. An annular liquid chamber E between the tubes 12, 14 contains a tubular rebound stop 36 and communicates with the liquid chamber C through a damping valve assembly 16 which includes two spring-loaded valves (Fig. 2, not shown) permitting different flow rates in each direction and restricted passages providing for limited flow when movement is insufficient to open the valves. A levelling valve 24 includes two valve spools 104, 106 for independent control of two struts 10, each spool 104, 106 being subject at one end to the pressure in the associated gas chamber B through a pipe 86 or 86a. Pistons 120, 124 acting on the other ends of the spools 104, 106 are subject to liquid pressure in a supply pipe 94 from an accumulator 29 charged by a pump 88 through a relief valve 92. Depending on the position of the associated spool 104, 106, liquid received from the supply line 94 through a pressure reducing valve 108 flows through a pipe 82 or 82a to increase the volume of the liquid chamber A, or liquid is exhausted from the chamber A to a reservoir 90 through a pipe 116. In another embodiment (Fig. 5, not shown) a single valve spool controlling two struts is subjected to the sum of the pressures in the gas chambers B of the struts.
