Title: A method and apparatus for the production of lace fabrics
IPC: D04B33/00
Filed: 1955-07-19
Abstract: 778,018. Crochetwork and lace. BERGISCHE GARDINENINDUSTRIE GES., and DITTRICH, R. July 19, 1955 [July 21, 1954], No. 20823/55. Class 74 (1). In forming a patterned lace-like fabric in which the warp threads K are crocheted into chains by needles 9, there is, in the case of selected filling threads S, superimposed upon the single-needle pitch traverse imparted to these threads S by the reciprocation of a member 2 bearing their guides 1, an additional traverse, by reason of the jacquard controlled projection, into the sheet of filling threads of members 4 borne by a holder 5 which also reciprocates, but with twice the amplitude of the holder 2. Filler threads, carried down below the plane of the needles by fingers 10 on a rockable shaft 11, are thus taken by one or two needles, according to the traverse imparted to them. Fig. 5 shows the incorporation of a filling thread S<SP>1</SP>, at times in the warp chain K<SP>1</SP> only and, at others, together with the adjacent filling thread S<SP>2</SP>, in warp chain K<SP>2</SP> also.

Abstract: 1,112,761. Batteries. SECRETARY OF THE ARMY U.S.A. 5 July, 1956 [11 July, 1955], No. 20929/65. Heading H1B. A battery having an electrolyte which is non-conductive at normal temperatures but which becomes conductive, generally by melting, when heated to an elevated temperature, has a depolarizer electrode provided with a first depolarizer material, e.g. ferric oxide, furnishing the normal operating voltage, and a second depolarizer material, e.g. molybdenum trioxide, furnishing a higher than normal voltage. Thus the battery may initially give 10-12 volts for 3-10 seconds and thereafter give its normal 6.5 volts, this action being suitable for the quick warming up of thermionic valve filaments. The depolarizer electrode may comprise a grid of silver, copper, nickel or iron and have the depolarizer material pasted thereon. The negative electrode may be of magnesium, calcium or an alloy of lithium, and the electrolyte may be of alkali or alkaline earth chlorides, bromides and nitrates in various combinations.

Title: Preparation of organosilicon halides
IPC: C07F7/16
Filed: 1945-08-17
Abstract: Allyl silicon halides are prepared by reacting elemental silicon with an allyl halide.  Preferably, the vapours of an allyl halide are brought into contact with finely-divided silicon at an elevated temperature, e.g. between 100 DEG  and 500 DEG  C., and an increased or reduced pressure may be used.  Alloys of silicon may be employed instead of silicon, e.g. ferrosilicon.  In an example, elemental silicon is dispersed in a fine cloud in a heated reactor and is contacted with vaporized allyl chloride to yield monoallylsilicon trichloride with minor quantities of diallylsilicon dichloride, polymeric allylsilicon chlorides, trichlorosilicone and silicon tetrachloride.  Specifications 575,667, 575,668 and 575,673 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the preparation in general of organo silicon halides by reacting elemental silicon with an organic halide, a number of which are specified.  This subject-matter does not appear in the Specification as accepted.

Title: Production of calcium phosphate
Inventor: MILLER RALPH
IPC: C05B1/04
Filed: 1951-09-11
Abstract: A method of producing monocalcium phosphate comprises forming a solution of strong phosphoric acid containing dissolved monocalcium phosphate, flowing said solution in a closed circuit, contacting the solution at a temperature of from 78 DEG  C-125 DEG  C with phosphate rock in one section of the circuit so as to dissolve the rock and increase the monocalcium phosphate content thereof, flowing the monophosphate-enriched solution to another section of the circuit, and there reducing the temperature sufficiently to crystallize a portion of the dissolved monocalcium phosphate and separating the solid monocalcium phosphate from the solution of phosphoric acid containing monocalcium phosphate, the monocalcium phosphate-depleted solution from the crystallizing step, after restoring the phosphoric acid content to substantially its original value, being employed for the further treatment of phosphate rock in the circuit.  The separated solid monocalcium phosphate may be hydrolyzed to dicalcium phosphate and phosphoric acid, the latter being returned to the monocalcium phosphate-depleted solution from the crystallizing step. Additional phosphoric acid may be added to replace that consumed during the process, or sulphuric acid may be added, producing phosphoric acid and calcium sulphate which is separated from the solution.  Sulphuric acid may also be employed to digest the residue of phosphate rock insoluble in phosphoric acid, thus producing a further quantity of phosphoric acid for use in the process.

[Class 40 (iii)] Signal peaks (e.g. synchronizing signals) passing through a condenser 9 are used to maintain the correct level of the signals by connecting a two-electrode valve 10 across the associated leak 4, and means are provided to counteract the deleterious effect of the load 2 (e.g. a wireless transmitter). (1) The loss in correction due to the load is compensated by applying to the diode 10 a greater signal voltage than is applied from a potentiometer 12 through the coupling condenser 9 to the load 2. (2) A special steady bias is applied to the diode to assist the initiation of the current of electrons, Fig. 4 (not shown). (3) The correcting valve 10 is connected in the grid circuit of the final valve 6 instead of in the anode circuit, Fig. 5. The correcting potential may be applied to the output lead 9, when the valve 6 merely reverses the phase of the signals, Fig. 6 (not shown). Specification 462,929 is referred to.
