Means for securing components 10 to a. channel member 1 comprises cross-members 5 tapped for the securing screws 11 and registering with openings 4 in the flanges 3 of the member 1. The screws pass through holes 2 in the channel web. A shoulder 8 on the member 5 locates it laterally, and the holes 9 in the member are offset so that the member may be re-positioned in the same recesses 4 but with the holes 9 registering with different holes 2. The cross-member 12, Fig. 4, may extend diagonally across the channel, which may be reinforced by an inner channel 14, Fig. 6, between which and the channel 1 the member 5 is received, the channels being connected by screws 19. A box construction (not shown) may be formed by reinforcing the channel member with an inverted channel member.

Abstract: 1,114,726. Lead accumulator electrodes containing coated particles. ZELLSTOFFFABRIK WALDHOF. 10 Feb., 1967 [12 Feb., 1966], No. 6459/67. Heading H1B. In electrodes of lead accumulators containing in the active material inert particles coated with a lignin sulphonic acid or salt thereof, the adhesion of the particles to the active material is improved by heating the lignin sulphonic acid or salt in powder form above 100‹ C. (preferably 150-220‹ C.) before coating the particles with it. Suitable particles are granules or short fibres of thermoplastic or thermosetting material, or glass or asbestos fibres. Suitable lignin sulphonates are those of alkali metals, alkaline earth metals and lead. The sulphonic acid or salt may amount to 6-20 wt. per cent of the particles. In Examples sodium lignin sulphonate is heated at 200‹ C. for 1 hr and the magnesium salt for 1¢hrs. at 210‹ C. They are applied in 25% aqueous solutions to P.V.C. chips.

Title: Improvements in and relating to bessemer converters
IPC: C21C5/48
Filed: 1939-02-27
Abstract: 529,135. Converters. PUENING, F. Feb. 27, 1939, Nos. 6480 and 6712. Drawings to Specification. [Class 72] A method of manufacturing a Bessemer converter bottom comprises a first phase of subjecting a mixture of refractory material and cokeproducing liquid or liquefiable substances to a medium or high temperature coking process, a second phase of filling-in with cement the voids formed between the individual pieces formed in the first phase, and a third phase of subjecting the coked and filled-.in mixture to a second coking or baking process effected at a lower temperature than the first coking process. The mixture of refractory material and coke-producing substances may be shaped to the final form of the bottom before the process referred to above is applied and the filling-in of the voids in the second phase may be assisted by a vacuum applied before the filling-in. The tuyeres may be formed by steel tubes or by apertures, the linings of which are produced by extruding cement in liquid form from a pipe having an annular slot. In a modification, the first phase may consist of making coke in a high temperature oven, and the second phase mixing the coke with a binding cement containing dolomite and shaping the mixture either before, during, or after the second phase.

Filed: 1927-03-09
Abstract: 279,020. Koks-und Halbkoks-Brikettierungs-Ges. Oct. 14, 1926, [Convention date]. Materials for making coke.-In the preparation of semi-coke briquettes, bituminous fine coal is briquetted with a binder which is either inorganic or comprises one or more water soluble organic substances with which a portion of the coal may be emulsified or is a mixture of the two kinds and the briquettes are submitted to a roasting and then a distillation temperature. In an example 95 kg. of coal graded from 7 mm. to O and containing 30-32 per cent of volatiles were mixed with 5 kg. of a binder consisting of 3 kg. of sulphite waste liquor and 2 kg. of clay. The briquettes were dried at about 150‹ C. for an hour and distilled at about 450-500‹ C. for about 2 hours. A portion of the coal dust may be emulsified with spent liquor to form the binder and size or water glass may be used instead of the liquor. A shaft or like furnace replaces the usual rotary tube furnace.

Title: Improvements in and relating to fuel injection pumps for high speed heavy oil interna
IPC: F02M59/04
Filed: 1932-03-04
Abstract: 384,499. Fuel-injection pumps. RENNERFELT, S. B., 2, Polhemsgatan, Stockholm. March 4, 1932, No. 6639. [Class 102 (i).] In a fuel-injection pump the plunger 2, Fig. 1, is of two diameters, the pressure chamber being beneath the shoulder thus formed. The shoulder controls the suction port 27 and the discharge port 5 and is formed with a helical edge 24 in order to permit variation in the time of closing of the port 5 and thus in the amount of fuel discharged. The plunger is raised by a cam 9 through tappets 10, 11 and the discharge stroke is effected by a spring 20. The plunger rests on the oil until the passage 5 is uncovered by a slide valve 4 operated by a crosshead on the tappet 11. The valve has a screwed engagement with the crosshead and is rotatable to vary the timing of injection. For this purpose the valve engages a slot in a spindle 17 rotatable by a lever 19. The plunger 2 is similarly rotatable by means of a spindle 16 and lever 18. In a pump for a six-cylinder engine three plungers 32, Fig. 2, each with a slide valve 34, are arranged in a circle in a cylinder block 33. The plungers are operated by a cam 39<1> and the valves by a cam 39‹. The tappets are arranged in a cage 61, which is adjustable by means of a lever 62 in order to vary the timing of injection. The plungers carry pinions 42 engaging internal teeth 43 in a cover 45, which is rotatable to vary amount of the discharge. The fuel enters by a passage 69 in a bolt 56 and passes through passages 59, 57 to an annular space 63. The discharge takes place through passages 35. Each valve 34 distributes the discharge to two points 36u, 36l.

Title: Improvements in and relating to apparatus for controlling the supply of a fluid
IPC: B64C11/42
Filed: 1940-04-17
Abstract: 538,107. Valves. BOULY, H. G. (Acrotorque Co.). April 17, 1940, No. 6974. [Class 135] Apparatus for controlling the supply of fluid to a mechanism to be actuated thereby includes means responsive to the rate of fluid flow through the apparatus which automatically causes the actuation of an electric switch controlling the means, such as an electrically driven pump, supplying fluid to the apparatus and the closing of a valve which controls the flow of fluid through the apparatus. As shown in the Figure, an electrically driven pump connected to a supply port 7 supplies fluid to an outlet 8 leading to a mechanism to be operated under the control of a valve 21. Fluid is exhausted from the outlet 8 to an exhaust conduit 9 leading back to a fluid reservoir under the control of a valve 15 co-operating with a ported seat 18 connected by a spindle 22 with the valve 21. The exhaust valve is shut and the supply valve opened by depressing a lever 10 against the action of a spring 11. At the same time an electric switch connected by a link with the lever 10 is closed to complete a battery circuit through a relay which in turn starts the motor driving the pump supplying the device with pressure fluid. The lever is held in the depressed position by a pivoted catch 33 adapted to snap over the exhaust valve under the influence of a spring 34. As fluid flows to the outlet 8 it acts on a pivoted vane 26 with an eccentric control surface moving it against the action of a spring 27. The vane has an arm taking between collars on a reciprocating rod 29 provided with a coned head 30 adapted when the vane is moved by the fluid flow to snap over a spring pressed pawl 31 mounted in the catch 33. When flow ceases the spring 27 overpowers the spring 34, releases the catch 33 and permits the supply valve to close and the exhaust valve open. On depressing a press-button 35 the head 30 is released from the pawl 31 and on the release of the press-button the device returns to its initial setting. Specifications 528,519 and 528,621 are referred to.
