Title: Process for the preparation of ortho-hydroxycarboxylates and ortho-hydroxycarboxylic acids
IPC: C07C51/15
Filed: 1935-07-26
Abstract: Aromatic o - hydroxycarboxylates and o-hydroxycarboxylic acids are prepared by passing carbon dioxide into a suspension of a dry, pulverized phenolate (cresolate or naphtholate) in an indifferent liquid medium having a boiling point above 100 DEG  C., the phenolate being potassium phenolate alone or a mixture of potassium phenolate and sodium phenolate, or sodium phenolate mixed with a potassium salt other than the phenolate.  The phenolates are prepared by mixing molecular quantities of alkali hydroxides and phenol diluted with an indifferent hydrocarbon and distilling till no more moisture comes over.  Examples describe the use of sodium phenolate mixed with potassium phenolate, chloride, or carbonate in heavy benzol and of potassium o-cresolate and b -naphtholate in tetrahydronaphthalene.  A small pressure may be used.  The Provisional Specification refers to the intermediate production of the phenyl carbonate below 100 DEG  C. Specification 384,619 is referred to.

Abstract: 1,048,242. Friction clutches. HEENAN & FROUDE Ltd. May 28, 1963 [Oct. 16, 1962], No. 21349/63. Heading F2C. [Also in Division H2] A secondary coupling 15, between driving 11 and driven 12 shafts, is engaged when the means for energizing a primary coupling 14, which is energized to vary the torque transmitted in accordance with load, provides a predetermined output torque. The primary coupling 14 is an eddy-current clutch of the kind described in Specification 2,855,527, having a stationary field coil 37, an inner rotor 33 rigid with the output shaft 12 and an inductor 32 rigid with the input shaft 11, the coil 37 being energized in dependence upon output shaft speed as sensed by a permanent magnet tachometer generator 50 to maintain the speed of shaft 12 constant. Upon excitation of the field coil above a predetermined point, the flux path changes from A to B to attract the armature 55 of the secondary friction clutch 15 into contact with a friction lining 56 and couple the shafts 11, 12 without slip. A plastic ring 70 is inserted in the rotor 33 to form a magnetic bottleneck to force the flux lines round the friction lining. The armature 55 is attached to radial arms 60 mounted on pins 61, secured to the inductor 32, allowing axial engaging movement against springs 65. A radial shield 75 prevents the ingress of friction material dust to the eddy current clutch gap 32<SP>1</SP> and ducts in the outer casing 13 provide for cooling air.

Title: Improvements in or relating to non-metallic resistors and methods or making them
IPC: H05B3/06
Filed: 1930-07-15
Abstract: 365,081. Self-supporting resistances; resistance materials ; couplings ; depositing by arc discharge. CARBORUNDUM CO., Ltd., Trafford Park Road, Manchester. -(Assignees of Heyroth, A. H. and Cox, G. C. ; Niagara Falls, New York, U.S.A.) July 15, 1930, No. 21442. Convention date, July 29, 1929. [Classes 37, 38 (i), and 41.] A non-metallic resistance is composed principally of silicon carbide, the contactmaking part or parts being impregnated with silicon, aluminium, nickel or alloys thereof. The contactmaking ends of a rod 5 of silicon carbide which may be preheated is dipped into the crucible 3 of an electric furnace 2 containing molten silicon 4 and the crucible is heated to a temperature (about 2100‹ C.) high enough to cause the boiling silicon to impregnate the end of the non-metallic rod 5. Silicon in granular form slightly in excess of the amount required for impregnation may be introduced into the crucible and heated with the silicon carbide rod, the excess silicon being volatilized in order to remove any particles of silicon adhering to the resistance. Further heating to a higher temperature in the case of silicon impregnation causes the silicon to alloy with the silicon carbide. Alternatively, the resistance may form one electrode of an electric arc, a piece of the substance with which it is to be impregnated being supported on the end of the resistance and an arc struck between it and a carbon rod forming the other electrode. Alternating or direct currents may be used. The Specification as open to public inspection describes a method wherein the resistor forms one electrode of the arc and the impregnating material the other electrode. Specifications 18749/06, [Class 37, Electricity, Measuring &c.], is referred to.

The drum may be supported on wheels.located beneath it, or may be provided with journals 2, 3 mounted in bearings, and is rotated through gearings or through a pulley 4 and belting. The stirrer 5 may act also as a temperature regulating device, and consist of a zig-zag shaped coil through which a heating or cooling fluid is supplied through inlet and outlet pipes 6 passing through the bearings 2, 3 and connected by screw-threaded joints to the ends of the coil. The curd cutter may comprise a frame provided with a sheet of wire gauze or an open mesh grid, or may consist of a series of wires extending across the centre of the frame, a perforated metal plate being mounted at each side of the wires. The drum is provided with an opening extending the full length thereof through which the working members can be inserted, the opening being closed by a lid which may be replaced by a straining frame provided with a filtering cloth. For use in separating the whey from tough curd, a crushing device is provided comprising a pair of geared rollers 11, 12, Fig. 7, carrying pins or teeth, the device being mounted in an open-work frame adapted to be inserted through an opening in one end wall of the drum. One or both of the end walls of the drum may be detachable for cleaning purposes, and the drum may be provided with one or more inspection openings. If desired, instead of separating the whey by straining, the curds and whey may be discharged into a receiver containing curd moulds which are covered by a plate provided with perforations for conducting the curd to the moulds, one end of the receiver being provided with a strainer through which the overflowing whey passes to an outlet pipe. In use, the drum is charged with milk which is brought to the desired temperature by circulating a heating or cooling fluid through the coil 5, the drum being rotated slowly ; the ingredients for coagulating the milk are added, the drum is rotated, the coil 5 is removed and the drum allowed to stand until coagulation is complete ; one of the cutters is then inserted in the drum and rotation continued until the curd is comminuted, when the coil 5 is substitutted for the cutter and the rotation continued ; the curds and whey may then be discharged into the receiver, or the whey may be strained off and the curd further treated in the drum by rotation either in the presence of the coil 5 or of the wire and perforated metal cutter. If the curd is tough, it may be broken up by the crushing device before separating the whey.

Inventor: THOMAS ALFRED WILLIAM
IPC: B28C7/08
Filed: 1959-06-24
Abstract: 950,060. Fluid-pressure apparatus. PLESSEY CO. Ltd. June 10, 1960 [June 24, 1959], No. 21634/59. Heading F1P. A fluid-operated actuator comprises a piston 1 which at the end of a relatively-long stroke is automatically reciprocated over a relativelyshort part of its total available stroke. The piston is, on one side, connected to an exhaust port 8, and, on the other side, connected by an inlet port 5 to a source of fluid pressure. The fluid pressure moves the piston 1 to the left and also acts on the end of a valve 10 which may be carried by the piston or the cylinder and is urged to a position opening a port 12 so that the fluid pressure aids a spring 19 to retain a valve 15 in a position closing a passage 16, 17, 18 leading from one side of the piston to the other. Towards the end of the stroke of the piston to the left, the piston may abut a buffer spring 9 and a rod 20 on the valve 10 engages the end cover 7 of the actuator to move the valve past the port 12 until the latter is open to the left-hand side of the piston. The pressure acting on the left-hand end of the valve 15 drops and the pressure from the source moves the valve 15 to open the passage 16, 17, 18. The resulting drop in pressure on the right-hand side of the piston permits the spring 9 or the load moved by the actuator, which may be the hopper of a cement mixer, to move the piston to the right until the fluid pressure from the source acts to move the valve 10 to its original position thus again reversing the direction of movement of the piston. The speed of the piston is controlled by the pressure of the fluid source or a metering device in the port 5 and the length of the to- and-fro movement at the end of the stroke of the piston determined by the length of the valve 10.
