Patent GB-125471-A (GB)
Title: Improvements in or relating to Submarine Mines.
IPC: F42B22/16
Filed: 1916-08-19
Abstract: 125,471. Vickers, Ltd., and Elia, G. E. Aug. 19, 1916. Mines, marine. - Relates to submarine mines of the kind in which a weight is attached beneath the mine to the mooring cable and is released at a given depth and falls on the anchor, causing the cable drum to become locked and the mine to be moored at the desired depth. According to the invention, the release of the weight is performed by a small float instead of by an hydrostat. in the form shown, the weight I is fixed to a tube i which is threaded over the mooring cable D and is held up against a stop J by radial pins j<1> confined by a sleeve h; and the small float K is attached by a line L to a bell-crank lever h<3>, which is pivoted to the sleeve h and is held in place by a split pin h<4> and if desired by a shear-pin also. The split pin h<4> interlocks the sleeve h and the weight I and confines a coiled compression spring h' within the sleeve. When the mine is dropped into the sea it sinks; but on touching bottom a spring pawl G is relieved of the pull of a small weight C and releases the drum E of the mooring cable, allowing the mine A to rise from the anchor B. The small float K, normally located in a pocket at the side of the anchor, rises away as soon as the mine is submerged and pulls the pin h<4> out, but holds up the sleeve h until the float reaches the surface during the ascent of the mine after its release from the anchor. The spring h<1> then depresses the sleeve h releasing the pins j<1>, which are wedged aside by the tube i; and the weight I, being thus released, falls along the mooring cable D on to a lever M, which pushes a pawl m<3> into locking engagement with the drum E. The pawl m<3> is normally held away from the drum by a spring catch, which yields to the blow of the falling weight I. The Provisional Specification also describes the use of a cord connecting the small float to a device on the anchor for releasing the small float.

Title: Contact mass for use in the preparation of organo halogenosilanes
IPC: C07F7/16
Filed: 1951-05-21
Abstract: Alkyl- or aryl-halogenosilanes are prepared by heating silicon in the presence of copper and calcium, magnesium, beryllium, strontium, barium, germanium, titanium, zirconium or cerium, or p  any mixture of these metals, with an alkyl or aryl halide.  The reaction gives rise mainly to the mono- and di-alkyl- or aryl-halogenosilanes.  The silicon, copper and other metal may be employed in the form of an alloy.  The calcium and silicon may be present as calcium silicide. In an example, methyl chloride is passed over a heated mass containing silicon, copper and calcium or titanium to form methyltrichloro- and dimethyldichloro-silane as the main products, and a minor amount of trimethylchlorosilane.ALSO:A contact mass, for reaction by heating with an alkyl or aryl halide to prepare alkyl or aryl halogenosilanes, contains silicon, copper and calcium, magnesium, beryllium, strontium, barium, germanium, titanium. zirconium or cerium or any mixture of these metals, e.g. in the form of an alloy.  The calcium and silicon may be present as calcium silicide.  The calcium, magnesium, beryllium, strontium, barium, germanium, titanium, zirconium or cerium or any mixture of these metals may be present in a proportion of 1 to 5 per cent. based on the total weight of mass. Preferably, the mass contains silicon, copper and calcium or silicon, copper and titanium.  The mass may be prepared by fusing silicon with the metal other than copper, pulverizing the resulting mass and mixing it with copper preferably in the form of a powder and, if desired, a compound volatile at high temperatures such as an ammonium salt, and the powder thus obtained is wetted, moulded and heated in an atmosphere of oxygen free hydrogen.  In an example, commercial silicon is fused with 3 per cent. of calcium silicide (containing 33 per cent. calcium) and with 5 per cent. titanium, the proportions being based on the total weight of the mass, the resulting alloys are pulverized and 90 parts of each of the powders are mixed with 10 parts each of copper powder and ammonium bicarbonate.  The mixtures thus obtained are wetted, moulded, heated and sintered in a atmosphere of oxygen free hydrogen.

Filed: 1960-04-05
Abstract: 890,693. Weighing apparatus. KEMPTON, J. April 5, 1960, No. 12055/60. Class 143. A predetermined weight of liquid, particularly paint to be tinned, is dispensed by apparatus comprising a valve unit 11 in which a plunger is vertically reciprocable with respect to an outlet closable thereby, and a weigh beam 24 which by means of electrical connections therewith controls the operation of the plunger so that the outlet is first partially closed to allow a dribble feed and ultimately fully closed, a spring device 35 acting on the weighbeam during the bulk feed. The plunger 13 (Fig. 2) is raised by the energization, through a push-button start switch (not shown), of a solenoid 17 which pulls down one end, as shown, of the lever 16. When the switch 29 is opened by the initial tilting of the weighbeam, the solenoid 17 is de-energized and the plunger 13 falls to the dribble feed position shown. As the beam continues to move the spring device 35 no longer influences the beam and, when the switch 30 is subsequently operated a solenoid 22 is energized thereby to withdraw the apertured plate 19 from its engagement with a collar 20 of the plunger 13 and allow the valve outlet 12 to close fully. Both the switches 29 and 30 and also the spring device 35 are adjustable by screws (Figs. 5 and 6, not shown). A micro-switch 34 operated when the slide 18 is withdrawn may be employed to effect automatic re-opening of the start-switch in readiness for the next operation of the apparatus. A handle 40-connected to a shaft 41 having projections 42, 44 engageable respectively with a pin 43 on the connecting rod between the solenoid 17 and the beam 16 and with a connection 45 to the slide 18-may be incorporated to allow for alternative manual operation of the valve unit.
