Title: Improvements in or relating to the manufacture of phosphatic materials from bones and the like
IPC: C05B11/12
Filed: 1933-01-13
Abstract: Anhydrous dicalcium phosphate (CaHPO4) is obtained by heating the previously prepared hydrated phosphate in suspension in water at atmospheric pressure, separating the solids and drying. Phosphatic material such as bone is extracted with dilute mineral acid and hydrated dicalcium phosphate precipitated by milk of lime.  The precipitate is put into a filter press and the filter cake suspended in water which is heated to boiling at atmospheric pressure.  The water may be removed by vacuum filtration while still hot and the product dried at elevated temperature, for example in a current of air at 60 DEG  C.  It is used in the manufacture of baking powders, flour improvers and the like. Specifications 4371/87, [Class 1 (iii)], and 388,663, and a known process in which the hydrated salt is dehydrated by heating with water in a tube at 150 DEG  C. are referred to.

Abstract: 191,960. Herbert, Sir A., and Lloyd, A. H. Jan. 17, 1922. Attachment for inserting bolts and screws; studding chucks.-In chucks for holaing screwed work and adapted particularly for screwing studs and the like into place, the engaging threads on the work and the chuck are locked by a transverse wedge operated by a cam or the like on a rotary portion of the chuck. The apparatus may be operated by machine or by hand. The bcdy A, Fig. 1, is yieldingly driven through friction washers G and a shank F, and is bored to receive a member A<2> which is permitted a limited angular movement against the resistance of a spring A<11>, Fig. 3. A transverse wedge C, Fig. 1, sliding in the member A<2> is of such a length as substantially to occupy the full diameter of an eccentric portion C<5> of the bore in the body, and is adapted to operate an axial thrust-pin D in a detachable threaded work-bush B which is secured in the part A<2> by a cotter B<3>. The bushes B are interchangeable. The arrangement is such that in. the normal driving position the pegs A<9>, A<12> are in contact and the thrust-pin is fully depressed, but on reversal of the chuck after the stud has been inserted, the member A rotates independently of the part A<2>, and slides the wedge transversely, thereby releasing the locking pressureon the stud.

Abstract: 719,092. Feeding pipes to endless conveyers. HERMAN PNEUMATIC MACHINE CO. Jan. 21, 1952, [July 14, 1951.] No. 1639/52. Class 78 (1). [Also in Group XXII] Elongated articles such as pipes formed in a centrifugal casting machine are discharged downwards in an upright position and then laid on a conveyer so that the axes of the articles are parallel to the direction of movement of the conveyer. The casting machine 'includes four flasks 3 arranged in a vertical plane forming an acute angle with the direction of movement of a horizontal conveyer 5 passing beneath the machine. When the cast pipes are discharged from the machine each drops through a generally tubular member 9 and rests with its lower end on a support 7, as shown at A in Fig. 1. The support is preferably covered with a cushioning material such as sand. Below the upper part which retains the tube in approximately vertical position, each member 9 is cut away at 10 on the side facing in the direction of travel of the conveyer sufficiently for the tube to pass through. Behind each member 9 is a pusher 12 on a shaft 11, all said shafts being coupled by arms 13 to a rod 15 operable by a piston in a cylinder 18 so as to push the lower ends of the tubes off the supports 7 and on to the conveyer, by which they are successively moved through the positions B, C and D to the position E in which they are resting wholly on the conveyer. As shown in Fig. 4, a single conveyer may serve two casting machines S and S<SP>1</SP>. Specifications 650,683 and 719,111, [both in Group XXII], are referred to.

Abstract: 654,244. Gas turbine plant. DOWTY EQUIPMENT, Ltd., Jan. 20, 1947, No. 1832. [Class 110(iii)] [Also in Group XI] A liquid-fuel supply system for spill burners of an aircraft continuous combustion turbine engine comprises an engine-driven circulating pump 10, Fig. 1, which maintains a maximum flow of fuel in a circuit including the swirl chambers of burners 1 without causing any discharge from the latter, an engine-driven supply, pump 13 for supplying fuel to said circuit in the quantity required to maintain a desired engine speed or to effect any change thereof, a pilot-controlled variable metering valve 15 in the passage 16 for fuel flowing to the circuit, and means responsive to variations in the setting of the metering valve 15 whereby to vary the stroke of the pump 13, if of the variable stroke type, or to vary the effectiveness of a byepass across the pump 13 if of the fixed stroke type. Each pump 13 or 15 comprises a ported valve spindle 17 around which rotates a radial cylinder assembly having pistons 19 provided with slipper bearing pads 20 running inside a track ring 21, the eccentricity of which with respect to the axis of the valve spindle 17 determines the operative strokes of the pistons, the ring 21 of the pump 10 being of fixed eccentricity and mounted to rock about a pivot 22 by the action on a finger 23 of a pair of pistons 24. The latter are subjected to the opposing pressures of a spring and of the delivery line 26, which is variable in accordance with the setting of the metering valve 15. The supply pump 13 may, alternatively, inject into the circulating flow in the supply line between the circulating pump and the burners. A modified system is described in which the supply pump has a fixed displacement and is associated with byepass containing an adjustable spring controlled relief valve the flow through which is dependent upon the setting of the metering valve 15. The burner nozzle 1, Fig. 2 comprises concentric tubes, fuel being supplied through annular passage therebetween to be injected through tangential passages 7 into the swirl chamber 6. Atomized fuel is discharged through the orifice 8 and excess fuel returns through the orifice 9. According to the Provisional Specification the speed of the gas turbine engine may be controlled by a governor as described in Specification 595,152.

As shown, the hot gas channels 10 are formed by a baffle member 12 and the heat-receiving portions of the side walls in the channels 10 have heat-conducting ribs 41. The easing 8 surrounds the member 12 and forms therewith an air uptake providing at the same time an insulation barrier between the pan and the casing. Heat insulating material such as asbestos is provided between the vertical front wall 5 of the pan and the casing 8. A thermostat (not shown) controlling the burners may extend into the pan through a tube 38. Asbestos packing 40 is placed horizontally above the flue outlet and below the hob to provide for heat insulation of the latter. The pan unit is shown as being fixed in an enclosing casing 37.
