Abstract: 852,821. Inductors. HIRST ELECTRONIC Ltd. Jan. 31, 1958 [Feb. 8, 1957], No. 4407/57. Class 38 (2). The A.C. winding 15 of a variable saturable reactor encircles the middle limb 12 of a core having two outer limbs 11, 11 carrying D.C. control windings 20, 20. The middle limb is transversely divided by an airgap 26 and longitudinally partly divided by slots 30, 30, so as to form branches in which the control flux 31, 32 passes in opposite directions when windings 20, 20 cause it to pass in opposite directions in the outer limbs 11, 11.

Title: Preparation of alkali metal thiocyanates
Inventor: VERO ERIC
IPC: C01C3/20
Filed: 1954-02-16
Abstract: Alkali metal thiocyanates are produced by reacting sulphur with alkali metal cyanide at 100-110 DEG  C. in an aqueous solution of the alkali metal thiocyanate of such concentration as to have a boiling point of at least 110 DEG  C.  A 50 per cent solution of the thiocyanate containing a dispersing agent, e.g. sodium alkylated naphthalene sulphonate, is heated to 100-110 DEG  C. and successive additions of cyanide and sulphur are made thereto, with stirring. The sulphur should always be in excess.  Water should be added to maintain the original thiocyanate concentration.  The resulting mixture may be diluted with water and filtered to remove excess sulphur.  When anhydrous potassium or lithium thiocyanates are being prepared the filtered liquor is evaporated to a boiling point 135-145 DEG  C. and cooled to room temperature to crystallize the salt.  When anhydrous sodium thiocyanate is being prepared the filtered liquor is evaporated to a boiling point 140-150 DEG  C. and cooled to above 30 DEG  C., e.g. 50-60 DEG  C. to crystallize.

Abstract: 526,241. Diamond &c. tools ; alloys. ROLLAND, F. W. Feb. 11, 1939, No. 4575- [Class 124] [Also in Group II] In a process for making diamond drill bits and like abrasive tools, the end of the tool to be faced is placed in engagement with the exposed surface of a mass of granular or powdered alloy above a plurality of diamonds on the bottom of a die, the mass of alloy is heated to a sintering temperature, and a suitable pressure is applied to the die to cause the alloy to be compressed to form a solid tip secured at the end of the tool and holding the diamonds. The alloy contains copper and tin, with or without cadmium, the particles having an affinity for one another and for the metal of the tool. Preferably the alloy contains 88 per cent. copper, 10 per cent. tin, and 2 per cent. cadmium. Instead of separate diamonds, the alloy may contain diamond dust. Apparatus for carrying out the process comprises a die member consisting of a base 21 with a central core 22 and a ring part 23 providing an annular space corresponding to the annular steel bit 25 which is to be diamond faced. Grooves 27 are provided in the base 21 to hold the diamonds, and the comminuted metal powder 24 is placed in the annular space with the bit 25 and a threaded cap 26 pressing thereon. The assemblage is placed on the bed-plate 6 of a press and subjected to the pressure of a block 12 attached to a screwed spindle 10. Heat is now applied by means of a burner 15 projecting through an opening 14 in a surrounding wall 13 of refractory material to cause the metal powder to sinter. Hydraulic pressure is applied by a ram 17 acting on plunger 8 projecting through the plate 6 and the plastic mass enters radial grooves 25a in the bit end to unite the tip to the bit.

Title: Improvements in automatic control apparatus
IPC: G05B11/01
Filed: 1938-02-15
Abstract: 515,296. Fluid-pressure servomotor-control systems. KENT, Ltd., G., and IVANOFF, A. Feb. 15, 1938, No. 4738. [Class 135] [Also in Group XXXV] A method for regulating an industrial plant to maintain a variable therein, e.g., temperature, at a predetermined value consists in causing a regulating device, which in response to change in the variable sets up a controlling effect, to set up a secondary control effect which oscillates at a higher frequency than the natural hunting frequency of the plant and regulating device alone and in applying the secondary oscillatory effect to modify the original control effect. In the arrangement shown in Fig. 1 a main regulating valve 2 is actuated by fluid pressure acting on a spring loaded diaphragm under the control of a pivoted baffle 7 working between nozzles 8, 9 in a fluid pressure conduit 10. The baffle 7 is actuated by a floating lever 4 linked at one end to a member 1 the movement of which is responsive to the variable and at the other to a bellows 20. This bellows is connected to the conduit 10 through a series of capacities 16, 17. 18 and capillaries 13, 14, 15. In a modification the baffle 7 controls the direct supply of fluid pressure to one Bourden tube and the supply through a capacity and adjustable restriction to a second Bourden tube. These tubes are coupled to a third tube and actuate a second pivoted baffle which baffle simultaneously varies the supply of pressure fluid to the main regulating device and also the supply, through a series of capacities and adjustable constrictions, to the third Bourden tube. In the arrangement shown in Fig. 3 a main valve 2 is actuated by a reversible motor 48 controlled by a two-way switch 45, 46, 47 actuated by the responsive member 1. A Selsyn motor 49 responsive to movements of the valve transmits an electrical impulse to a Selsyn receiver 50 . which tensions on a spring 51 acting on the switch arm 44 and also moves a contact 52 over a variable resistance 53. This resistance controls the current supplied to a heating coil 54 surrounding a bi-metallic strip 55 coupled by a spring 56 to the responsive member 1. In a modification a second bi-metallic strip is coupled to the strip 55 and is heated by a coil in series with the coil 54 and arranged in a tubular heating element to have a considerable lag. According to the Provisional Specification the responsive member may be connected to transmit a control impulse not only to the main control valve but also through a first spring to an escapement device through a second spring in series with the first to a second escapement device and through a third spring in series with the other two to a third escapement device and through a fourth spring to a Selsyn motor remotely coupled to a Selsyn transmitter operated by the main valve. Reference has been directed by the Comptroller to Specifications 234,194, [Class 135], 405,665, 440,115, [both in Group XXXV], and 478,518.
