Title: A turn-sensitive device
IPC: G01C19/56
Filed: 1965-06-25
Abstract: 1,102,477. Turn-sensitive devices employing vibrating masses. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. June 25, 1965 [June 27, 1964; March 5, 1965], No.27021/65. Addition to 1, 049, 794. Headings G1C and G1N. A turn-sensitive device comprises a symmetrical cylindrical resonator 1 excited to longitudinal oscillation by an electro-mechanical transducer 11 and in which torsional oscillations will occur within the resonator as it is turned about its cylindrical axis, the resonator vibrating longitudinally in the mode in the direction of its axis, and the torsional oscillations being in the #/2 mode. The transducer 11 transmits its longitudinal vibrations to the resonator 1 via coupling elements 3, 10 which give as weak a coupling as possible. These vibrations are fed via similar coupling elements to an output transducer 12 whose output signals may be fed to an amplifier (not shown), and then fed back to the transducer 11. If the resonator is turned about its cylindrical axis torsional vibrations are set up at the same frequency as the longitudinal vibrations. The cross-sectional area of the resonator 1 is reduced at the nodal points of the longitudinal vibrations in order to adapt the # longitudinal resonance to the frequency of the #/2 torsional resonance. The torsional vibrations are fed by way of coupling elements 4 to a magnetostrictive transducer 5 comprising a tubular magnetostrictive oscillator 6, a magnet 8, and an annular core winding consisting of a single turn 7. The output from the transducer 5 is supplied to a transformer 9 and thence to a measuring instrument. The coupling elements 4 are shown connected to nodal points for the torsional vibrations, but alternatively the pick-up of the torsional vibrations may be effected through the use of an additional torsional resonator connected similarly to one of the elements 10 in Fig. 1. This additional resonator is arranged to damp out longitudinal oscillations so that the coupling elements which are connected to the additional resonator only pick-up torsional oscillations.

Title: Method and apparatus for transferring a picture-carrying layer from one cinematograph film to another
IPC: G03C11/12
Filed: 1951-11-19
Abstract: 686,974. Photographic processes. TECHNICOLOR MOTION PICTURE CORPORATION. Nov. 19, 1951 [May 19, 1951], No. 27092/51. Class 98 (ii). A method of transferring a picture-carrying layer from one kinematograph film to another comprises continuously feeding the two films in registered contact and pressing them together while the face of the layer is sufficiently tacky to cling to the new film lightly, subsequently heating the layer sufficiently to bond it tightly to the new film, and then peeling the new film and the layer from the old film. Apparatus for the method comprises means for guiding the films along separate paths into registered contact at one location, thence along a common path to a second location, and thence along separate paths; means along one of the firstmentioned separate paths for softening the face of the layer sufficiently to render it tacky, means at the first location for pressing the films into registered contact, means between the locations for heating the layer sufficiently to bond it tightly to the new film, and means for peeling the new film and the layer from the old film at the second location. The method may be used, e.g. with multilayer films in which the layers (except the last) are transferred after exposure to other films for treatment, such as the film described in U.S.A. Specification 2,367,665. As shown, a three-layer film M and a blank film N are unwound from reels 1, 2 respectively and are led through a wetting tank 6. This renders the top layer of film M tacky, and may slightly loosen it from the film. The films are then pressed together by rollers 7 and are then seated on a pin belt 3 by an endless sealing belt 8. Pin belt 3, driven by drums 5, carries the films to a roller 12. During this travel the films adhere sufficiently strongly not to slip. The films are led over roller 12 and through a heating bath 13 which may contain water at about 90‹ F., which causes the top layer to adhere firmly to film N. The films are then led through unheated water in a tank 18, and are stripped apart below the surface of this water. As the films are led away they are sprayed by nozzles 19 to remove the remaining adhesive. The second layer may be transferred to a second blank film in a similar manner.

Filed: 1961-07-26
Abstract: 935,569. Calculating apparatus. TITUS MANUFACTURING CORPORATION. July 26, 1962 [July 26, 1961], No. 27149/61. Class 106 (1). A calculating appliance gives noise criteria and other characteristics of air diffusers over a range of air flow rates. The appliance (part shown in Fig. 5) consists of a body 10 receiving three slides 11. The top slide is set so that the air flow is against the mark CFM on the body. Against the orifice area scale on the body the outlet velocity of the air can be read off, as can the diameter of a round orifice corresponding to a particular velocity. The bottom edge of the top slide carries noise figures which are read off against the area or round diameter scales. The noise figures are corrected for particular types of diffusers from a table carried on the top slide. The lower slides and fixed scales are concerned with the throw or distance from the diffuser at which air velocity has fallen to a predetermined value, and the drop index or distance below the diffuser at which the velocity will have fallen to a predetermined value. The reverse side of the appliances has logarithmic scales for calculating the area of a duct of rectangular form given length and breadth, and other scales for giving the true area given nominal length and breadth. Air flow through a given area orifice, given the air speed, can also be found from other scales. The pressure of air, given the velocity, can also be read off.

In a high voltage cartridge fuse an indicator or trip mechanism is connected in shunt with a portion of the length of one of a plurality of fusible elements, the shunted portion of the element being modified so as to preferentially melt under low over-current fault conditions thereby diverting current through the trip mechanism to operate it. The fuse is substantially as described in Specification 713,663, comprising a powder-filled ceramic casing 8 enclosing silver or copper strip or wire fusible elements 11 on a ceramic star core 10, with a trip mechanism comprising a charge 26 of explosive gas-producing material which can be actuated by a wire 27 to eject a striker pin 23 through one end cap 15 of the fuse. The mechanism is electrically connected, via the wire 27, between this end cap and a point 30 on one of the fusible elements 11. This shunted portion of the one element is provided with a rivet 35 (Fig. 4, not shown), of low-melting point metal such as tin, cadmium, zinc, lead or alloys thereof and may be restricted in crosssection, for example by an aperture as at 37. Under over-current fault conditions the rivet alloys with the metal of the fusible element to form a molten zone and thereby divert at least part of the fault current through the trip mechanism. The fusible elements 11 are provided with restricted sections 112 and portions 38 of low-melting point metal (Fig. 5, not shown). These, by their suitable positioning and dimensioning, and by virtue of the temperature difference between the central and terminal portions of each fusible element due to the end cap 15 acting as a heat sink, are arranged to fuse under high current fault conditions. The fusible elements 11 may be provided also with arc control ceramic beads 12. The strikerpin 23 may provide audible or visual indication of overcurrent fault conditions and may operate contacts 41 to trip a circuit-breaker.
