Filed: 1948-07-20
Abstract: 638,852. Skinning fish. ROWTON, H. S. July 20, 1948, No. 19375. [Class 28(ii)] In skinning fish fillets by pulling a fillet against a fixed knife 57, the fillet being temporarily held on a rotary drum (11) spring pressed by' impaling. needles, the needles 25 are now positively held into the fish until the skinning is completed. The needles 25 are mounted in a block 18 carried round with the drum 11 and are moved in or out through holes during drum rotation by means of a fixed cam 30 operating on a roller 28 of a bell crank 20. A spring 24 merely holds the roller 28 against the cam 30. The needles have square heads to fit into a groove in the block 18 in which they are clamped. When a fish fillet is pushed by hand into a slot 15 in the drum a cam (54a) operated presser 51 presses the leading end of the fillet on to the needles 25 which are at this time held projecting through the perforations without yielding back. The presser 51 is provided with an adjustable friction pad to prevent rebound. The fillet is then carried round against the skinning knife 57. The flesh passes down a slide 61: The skin is carried round on the needles until they are retracted, and the skin is cleared from the drum by a scraping roller 43 rotating in the same diection at a higher peripheral speed. The roller 43 is formed with alternate rings of teeth spaced by grooves to allow a fixed comb to clear them of skin.

Abstract: 709,170. Massage appliances. FERRIER, A. P. S. Aug. 6, 1952 [Aug. 20, 1951], No. 19859/52. Class 81(2) An appliance for assisting the circulation comprises an elastic member having an aperture through which part of the body, for instance, a leg, may be inserted: The member becomes stretched as the appliance is moved along the body part and is retained, by appropriate means, in its maximum stretched condition while the appliance is returned to its starting point. In one form a rubber diaphragm 1<1>, having a central aperture 2, is secured to an annular frame 17 so that it may conventiently be passed over a leg. As it is moved upwards the rubber becomes stretched to a position 2c (1b in Fig. 4), and the resultant slack in cords 24, attached adjacent the aperture 2, is taken up by spring winders 23. Then, at the limit of the movement, a second annular frame 20, mounted adjacent the first, is pressed downwards against the latter, by means of handles 18, 21, so as to grip the cords securely. The appliance is then moved down the leg to the starting position, where the cords are released so that the diaphragm again constricts the leg. Various other arrangements are described for removing the constricting pressure during the downward movement, which include mounting a spiral diaphragm or a helical spring so that the central aperture may be opened by twisting the spring, attaching parts of the diaphragm to toggle levers so that the tension may be quickly released and mounting two halves of the diaphragm on diametrically arranged levers, resembling tongs, which may be readily opened to separate the two halves.

Abstract: 929,932. Velocity-modulated tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 17, 1959 [June 26, 1958], No. 20464/58. Class 39 (1). High-frequency electrical apparatus comprises an electron discharge device disposed at least partly within a waveguide 1, Fig. 1, a cavity resonator 2, 6 capable of resonating independently of the waveguide 1, and the cavity resonator having a coupling aperture or window and being so arranged within the waveguide that energy can be transferred from the cavity resonator to the waveguide directly through the aperture or window, the frequency of the oscillations set up in the cavity resonator being mainly determined by the dimensions of the cavity. The electron discharge device is preferably a reflex klystron. In Fig. 1 the reflex klystron has two copper discs 2 sealed through the envelope and forming together with a brass ring 6 soldered thereto the cavity resonator. The upper disc 2 is soldered to brass ring 8 and the lower disc is soldered to brass cone 11. In assembly the reflex klystron is plugged into the rectangular sectioned waveguide through its broad faces, the lower end of the cone 11 being seated in conical aperture 12 in the lower wall of the guide and the brass ring 8 contacting the upper wall of the guide through spring fingers 10. The reflex klystron is secured in position by a clamping annulus 13 which secures cone 11 to its seating 12. The brass ring 6 is made in two parts, which are soldered together during assembly. The spaces between the resonator and waveguide walls are dimensioned to be below cut-off so that all the wave energy flows unidirectionally to the load. A further coupling aperture may be provided at junction 15 so that some wave energy goes to the right-hand part of the waveguide the end of which is fixed or has a tuning stub or a tuning piston to pull the resonator frequency, e.g. to give a tuning range of 7% in the case where the coupling aperture of this guide section has the same dimensions as coupling aperture 7. In this case the two parts of the ring are separate and not joined together. Preferably, however, the guide has no frequency pulling effect on the cavity resonator. The following modifications are referred to: (a) The waveguide may form part of the vacuum envelope of the klystron, the vacuum being maintained by windows sealed across the guide. (b) the reflex klystron resonator is of the integral type, the coupling aperture 7 being closed by a window. (c) The cavity resonator is wholly within the evacuated envelope of the reflex klystron.
