Title: Improvements in or relating to impulse-operated devices
IPC: G01P3/66
Filed: 1958-10-06
Abstract: 859,227. Electric measuring systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 6, 1958 [Oct. 9, 1957], No. 31816/58. Class 40 (1). Apparatus for determining the speed of a vehicle along a road comprises two short lengths of coaxial cable laid transversely across the road a predetermined distance apart, each producing an electrical pulse between inner and outer conductor when subjected to the pressure of a passing vehicle, the tune between the pulses being measured. As shown, the pulse produced by the first cable K 1  is fed to a thyratron T 1  causing it to fire, reducing its anode voltage by the potential drop across a resistor R 1  and causing capacitor C to be charged through diode D 1 . The pulse from the second cable K 2  causes thyratron T 2  to fire, thus stopping the charging of capacitor C, the resultant voltage across C, measured by a valve voltmeter BV, being indicative of the time between pulses and therefore of the speed of the vehicle. Specification 592,362 is referred to.

Title: Method of and apparatus for reducing metal tube-ends in the manufacture of containers and bottles for compressed gases
IPC: B21D51/24
Filed: 1953-11-17
Abstract: 761,143. Pipe-end closing; making gas bottles. WEISSE, E. Nov. 17, 1953 [Dec. 19, 1952], No. 31834/53. Classes 83 (2) and 83 (4). [Also in Group XXVIII] In the manufacture of metal containers and bottles for storing compressed gas, a metal tube 3 has its end reduced by heating the end of the tube above the recrystallization temperature whilst it is being pressed in a heated die 1 and simultaneously cooling the mouth of the die and the adjacent part of the tube. The tube may be of aluminium and its end may be heated to 400‹ C. in the die which has electrical or gas-heating means 2 and is secured to the moving platen of a press. The tube end may in addition be heated separately and independently of the heated die. The adjacent part of the tube is cooled by water sprayed from an annular pipe 5. Alternatively or in addition the tube may be filled with water up to a fixed level which is maintained constant or it may vary according to the movement of the die 1. A neck portion 4 may be formed in one or more operations; the thickness of the metal in this portion will be increased in dependence upon the friction between the tube and the die which may be lubricated with colloidal graphite. In another embodiment, Fig. 5, jaws 8a actuated by wedge-cams 8 swage the metal of the tube into an annular groove in a collar 6. The tube and collar may subsequently be welded together externally. In another embodiment, Fig. 6, the end of the neck has screw threads 15 formed internally or externally thereon for engagement with a screw-threaded collar 6. The edge of the tube metal is sharpened to about 50 degrees and is deformed by engagement with the wedgeshaped end 16 of an annular groove in the collar, which end has an angle of about 60 degrees to effect a gas-tight seal. To prevent loosening of the collar a spot or short seam weld 14 may be provided. Lugs 10 for a bail 11 are provided on the collar. Other embodiments are described for closing the other end of the gas bottle to hemispherical or ellipsoidal form and for providing a collar in the partspherical end. Re-inforcing rings 12, Fig. 8 (not shown), may be provided internally or externally of the bottle.

Title: Improvements in or relating to governors, more particularly for gas turbine engines
IPC: F02C9/16
Filed: 1955-11-08
Abstract: 806,207. Gas turbines. BENDIX AVIATION CORPORATION. Nov. 8, 1955 [Dec. 22, 1954], No. 31929/55. Class 110 (3). [Also in Group XXIX] An engine speed governor, more especially for controlling the fuel supply to a gas turbine engine comprises fly weights 142 driven by the engine and acting on a valve member 176 which controls the pressure in a chamber 72 acting on a combined servo piston and fuel control valve 60. The member 60 reciprocates in a fixed sleeve 42 and has a control portion 64 coacting with ports 54 in the sleeve to control the flow of fuel from an inlet 24 to an outlet 17. Fuel under pressure also passes through a passage 110 and valve 112 to a chamber 70 where a pressure maintained at a constant value by the valve 112 acts on a piston portion 66 of the member 60 to bias the latter towards the right. Pressure fluid from the chamber 70 also passes through a passage 108 and restriction 118 to the chamber 72 where it acts on a piston portion of larger area than the portion 66. A leakage of pressure fluid from the chamber 72 through passages 120, 122 is controlled by the valve member 176 coacting with a seating 124 carried by the member 60 whereby movement of the valve member 176 is followed up by a corresponding movement of the member 60. A drain passage 100 leading from an annular groove 98 prevents the pressure in the chamber 72 from being affected by that in chamber 58. In the event of the member 60 failing to operate in response to operation of the valve member 176 an extension 178 of the latter, which has a lostmotion connection with the members 60, 124, operates the member 60 directly. A governor loading spring 162 is adjustable by an operator through a movable sleeve 160 slidable on a fixed sleeve 134. The degree of opening of the fuel valve 64 during acceleration of the engine is limited by a stop 86 which is adjustable by engine speed and compressor inlet temperature and coacts with an abutment 82 carried by the member 60. The abutment 82 also coacts with an adjustable minimum fuel flow stop 84.
