Title: Improvements in or relating to heating vessels by electricity
IPC: A47J37/06
Filed: 1927-06-30
Abstract: 299,818. Parkinson, J. June 30, 1927. Heating by electricity.-The body of a kettle or other utensil b is surrounded by one or more insulated resistances a, the ends of which carry terminal plates k attached to an insulating block f on which is formed the plug or socket members g by means of which the resistance is connected to the supply system. The resistance wire a is of sinuous form and arranged between insulating members c. It is surrounded by lagging d encircled by a clamping band e secured to the block f by screws m, j, and fitted with feet o for supporting the kettle. The terminal plates k are secured by screws l entering the members g. A rectangular shield carrying a socket for engaging the supply plug may be fitted over the block f and secured thereto by screws engaging holes n therein. An earthing pin p may be fitted to the block f. In a saucepan the end of the clamping band forms a spigot to which a hollow handle is attached. The terminal plates pass up through the handle to an insulating block at the top thereof.

Abstract: 135,235. Kestner, P. Sept. 14, 1918. Purifying saccharine liquids.-Beet juice is concentrated by heating under pressure for a short time and then cooling it by suddenly removing the pressure or otherwise. The resulting product is stated to contain the nitrogenous and other nutritious constituents of the juice and to be free from objectionable odour or taste. Juice of such concentration that it would boil under atmospheric pressure at 120‹ C. may be raised to 130‹ C. in a closed evaporator of the Kestner or other type, the heating not being allowed to last more than a few seconds to prevent caramelization. The steam produced may be used to dry the pulp from which the juice has been extracted.

Title: Improvements in variable speed power transmission apparatus
IPC: F16H39/14
Filed: 1920-06-02
Abstract: 167,349. Rayburn, E. M., and Rayburn, A. G. June 2, 1920. Clutches and speed-varying mechanism.-An hydraulic variable-speed power-transmission apparatus comprises a driving-shaft 12, Fig. 1, and a driven shaft 23 carrying a block 19 provided with pump cylinders 18 and motor cylinders 24, the pump pistons 17 being operated by springs and a swash-plate 16 on the driving-shaft, and the motor pistons being connected to a ring 27 rotatably mounted in a trunnioned housing 29 and connected by a universal joint to the block 19. Between the pump and motor cylinders is a distributing-valve comprising a seat 82 carried by the driven shaft, a plug 83 carried by the driving-shaft, and a non-rotatable member 84. The member 84 may be unseated by a pedal 86 so as to establish communication between all the pump cylinders and thus interrupt the drive. The position of the housing 29 and thus the speed ratio of transmission and direction of rotation of the shaft 23 is determined by hydraulic means comprising cylinders 37, 38, Fig. 2, the operating- liquid being drawn from a chamber 49 by a pump 43 and delivered through a controlling valve 33, the valve plug 35 being operated by a lever 36, and the resultant movement of the housing 29 acting to rotate the valve seating 34 to stop the flow when the housing has been moved through the same angle as the lever. In a modification, the reverse drive is obtained by rotating the valve member 84 through 180‹.

Direct current may be reversed at intervals (e.g. every 10 minutes) by switch 36. The electrodes are preferably formed with a pitted surface. In the apparatus shown, the feed water is passed through filtration, chemical-dosing and degassing unit 18, and then flows through condenser tubes 14 to be introduced into the first flash chamber. Part of the brine leaving the last flash chamber is recirculated through connection 26, and the remainder is discharged through outlet 28.

Title: Process for isomerising ketoximes
Filed: 1945-06-15
Abstract: Ketoximes are subjected to the Beckmann rearrangement to give amides or lactams in a process in which the ketoxime, dissolved in a solvent which distils at the reaction temperature, is added to hot sulphuric acid.  The concentration of the ketoxime in the solvent is such that the evaporation of the latter causes sufficient cooling.  Solvents specified are: benzene, cyclohexane, symmetrical dichlorethylene, saturated aliphatic hydrocarbons and the lower aliphatic ethers.  In the examples, caprolactam is prepared by treating cyclohexanone-oxime in solution in cyclohexane or ethylene dichloride with sulphuric acid.  The process may be continuous.

Abstract: 544,588. Weighing apparatus. BLACK & DECKER MANUFACTURING CO. Oct. 17, 1940. No. 15388. Convention date, Feb. 14. [Class 143] A manually portable platform device for weighing wheeled road vehicles, aeroplanes or the like comprises means for transmitting the load on the platform to a beam, a helical tension spring for balancing the beam, means for applying tension to the spring and measuring its elongation to determine the load, and a connecting means for connecting the spring to the end of the beam and to the tension applying means, the connecting means being disposed at each end of the spring so as to distribute the tension uniformly about the periphery of the spring and to avoid, in the balancing operation, any tendency to deflection of the axial line of the spring and maintaining the axis in a straight line. The load on the platform 1, Fig. 1, is transmitted by two platform-supporting levers to a beam 3 fulcrumed on a knife-edge 4. The beam is provided with two knife-edge bearing blocks 17 on each of which rests a knife-edged transfer block 12, Figs. 5 and 6, supporting the long end of a platform lever 2, the knife-edges 15, 18 being arranged at right angles to one another. The long end of the beam 3 rests on a conical pin 24 in a yoke 20 forming part of a plug 25 fitting into the lower end of the weighing spring 8. The plug is retained in the spring by four radially-directed pins 27, 271, 27<SP>11</SP>, 27<SP>111</SP>, situated between the coils so as to distribute the load equally and maintain a straight axis to the spring at all times. The upper end of the spring is similarly engaged by a plug 33 adjustable in height to tension the spring; by means of a screw 9 rotated by a handle 31; The rotary movements of the handle are trans mitted by a gear wheel 38 to a counter registering in pounds or other weight. The gear wheel may be released from the screw and rotated by a knob to effect zero adjustments of the counter. The beam 3 is limited to very small movements by adjustable stops 56, 57 and, when the platform 1 is loaded, is brought to its equilibrium position by turning the handle 31, the balancing position being indicated by a pointer 45 observed through a window 59. The pointer is pivoted on conical pivot pins 52 on a fixed bracket and engages the beam 3 by means of a pointed pin 54 in line with the axis of the spring. In a modification, the weighing spring 8 is arranged in a horizontal position and the load is transmitted from the beam 3 to the spring through a bell-crank lever. Specification 525,458 is referred to.

Abstract: 1350318 Sintered permanent magnets PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 April 1972 [6 April 1971 11 March 1972] 15672/72 Heading C7D A sintered anisotropic permanent magnet of the system M-R which includes M 5 R where M is Co with or without Fe, Ni and Cu and R is at least one of Y, Th and the rare earths, is made by orientating the crushed alloy in a magnetic field, optionally compacting the powder, and sintering above the critical temperature i.e. the highest temperature at which the sintered powder still shows ageing. The alloy is prepared and processed under conditions which prevent the oxygen content exceeding a critical value determined by reference to a graph of coercive force against sintering temperature at different oxygen contents. The maximum oxygen content is usually 0À5% and is achieved by wet grinding the alloy in an organic liquid with a boiling point <120 C and containing a fatty substance e.g. mineral, vegetable or animal oil as a metal wetting component. The orientated powders may be precompressed e.g. at 0À3KB and then isostatically compacted up to 20KB. Sintering is effected in an inert atmosphere or under vacuum e.g. at 1100C.
