Title: Improvements in x-ray tubes
IPC: G01C3/12
Filed: 1934-08-08
Abstract: 423,567. R÷ntgen-ray tubes. MULLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. Aug. 8, 1934, No. 22955. Convention date, Sept. 6, 1933. [Class 39 (i)] A tube, the anode of which has a funnel - shaped channel on the inner wall of which the X.rays are produced, has the source of electrons located entirely outside the channel, and at the end remote from the point where the rays emerge, the electrons being directed through the smaller mouth of the channel. The beam is so directed that the electrons impinge on the wall of the channel at a small angle. In one form, Fig. 1, the cathode 1 opens like a funnel on the side facing the anode 2, and the filament 3 is arranged in a recess 4 in it. The anode has a front surface parallel to that of the cathode and an aperture 5 through which the cathode ray enters the smaller end of the channel 6 after intersecting at the height of the smaller mouth. The X-rays emerge through a window 7. The anode may be sealed by a metal ring to the glass wall of the tube, and the cathode to a glass re-entrant stem. In a modification the anode and cathode structures are sealed to re-entrant stems at opposite ends of the tube so that the beam emerges laterally through a window in a metal portion in the middle of the tube.

Filed: 1938-08-03
Abstract: 510,924. Vehicle bodies. AUTO UNION AKT.-GES. Aug. 3, 1938, No. 22997. Convention date, Aug. 3, 1937. [Class 108 (i)] [Also in Groups XXV, X and XVII] In a wall structure built up from a plurality of synthetic resinous sheet-like pressings disposed in substantially the same plane, particularly for vehicle body-work, adjacent pressings are connected together by a deformable metal strip in one or more lengths co-extensive with the edges of the pressings, the metal strip comprising a head portion and a base portion, the head portion being deformed to press the edges of the pressings against a preformed abutment on the base portion. The metal strip may be of aluminium or of soft iron, and any gaps or grooves left on the outer face of the joint may be filled up or closed by a plastic synthetic resinous adhesive or the like. In the form shown in Fig. 1, the pressings 1, 2 are formed with flanges 3, and the metal strip is of split-pin section with a bulbous head 10 and legs 6, 7 to which a moulded rib 8 forming an abutment also of synthetic resinous material, is keyed by means of apertures 9. The lower ends of the legs 6, 7 may have flanged extensions of dove-tail shape which are bent over in opposite directions to engage correspondingly shaped depressions in additional pressings parallel to the pressings 1, 2 so as to press such additional pressings against the abutment rib to form a double-walled structure. Figs. 5 and 6 (not shown) illustrate four pressings connected together by a slidably engaging interlocking connection between the metal strips. Fig. 8 shows a modified metal strip formed from a flat band by slitting and bending to form oppositely directed lugs 17 with flanges 18 to form the abutment, and oppositely directed lugs 20 to form the head, the edges of the pressings being moulded with depressions to receive such lugs. Some of the lugs 20 may be left standing upright so as to secure in position a third pressing at right-angles to the other two pressings and carrying a metal plate which may be welded to such upstanding lugs. Fig. 12 shows a further form of metal strip formed from a flat band which is split and bent to form a deformable bulbous head and oppositely directed intersecting lugs 28 forming the abutment.

Title: Improvements in and relating to variable speed transmission
IPC: F16H61/02
Filed: 1933-08-18
Abstract: 427,470. Variable-speed gearing. REO MOTOR CAR CO., 1331, South Washington Avenue, Lansing, Michigan, U.S.A. Aug. 18, 1933, No. 23114. Convention date, Oct. 17, 1932. [Class 80 (ii)] Comprises epicyclic gearing which is controlled by centrifugal levers N, Fig. 1, and by slip in a plate clutch M so as to vary automatically in ratio between a definite low speed and solid drive. A sun gear B fast on a driving-shaft A<2> is connected to an internallytoothed ring D rigid with a driven shaft A' by an internally and externally toothed ring C meshing with both and supported on roller bearings on a built-up revoluble eccentric J, G, K which is prevented from turning backwards by a roller one-way brake O. The plate clutch M is adapted to connect a flange K<2> of the member K to a drum F rigid with the ring D. The levers N have T ends N<1> adapted to press the clutch plates together as the levers move outwards centrifugally from the position shown in Fig. 1, which illustrates the low speed position. The rollers of the brake 0 are jammed as shown in Fig. 2, and the gearing is operative to yield a definite reduced speed. As the speed of the driven shaft A<1> increases, the levers N move outwards so as partially to engage the clutch M. The revoluble gear carrier J, G K is thus caused to rotate forwardly so that the speed of the shaft A<1> increases. When the clutch M is fully engaged, the gearing turns solid on high speed. This automatic gearing is adapted to be used with manuallychanged gearing X comprising a reversing- train between the automatic gearing and the drive shaft A of a vehicle. To transmit a reverse drive, the gear carrier J, G, K of the automatic gearing must be prevented from rotating idly forwards. To this end, the part K has a flange K<6> with internal ratchet teeth K<7>. When a gear T is slid to the right of Fig. 1 to connect the reversing-train, a spring dog R is slid into the plane of the ratchet teeth K<7> to engage these teeth as shown in Fig. 2, so as to prevent said idle rotation. The dog R slides radially in a fixed guide Q<2> and has a shank R <1> which is pivoted at S to the shifter S of the reversing-train. The gearing X may be the two-speed and reversing gearing operated by segment and rack selector mechanism V<1> described in Specification 427,471.

Abstract: 845,814. Sealing by dielectric-heating. RHENOPACK, G.m.b.H. July 22, 1958 [July 25, 1957], No. 23453/58. Class 39(3). [Also in Groups VIII and XVII] Cushion type packages are formed from a flexible tube 1 being filled with a liquid or pasty material by first flattening an area to be sealed by a compressed air jet, then heat sealing the flattened wall parts together and finally cooling the sealed surface with the air jet. In Fig. 1 the heat sealing is performed by two high frequency electrodes 5 reciprocable against the tube 1 from within housings 2, the compressed air flowing from an annular passage 11 surrounding each electrode. In a modified construction, Fig. 4 (not shown), the housing .2 is constructed such that the air does not flow over the surface of the electrode 5 but escapes through an annular shaped orifice in the end face of the housing. In a further modified form, Fig. 5 (not shown), the compressed air passes through a bore in the electrode. As the housings 2 in Fig. I are moved towards the tube 1 they engage stops 14 to prevent contact with the tube 1, the electrodes 5 being propelled forwardly by inertia until they contact the tube 1 whereafter they are retracted by springs 8. In a modified construction the housing 2 may be moved towards the tube 1 by a first air operated piston and the electrode 5 is then moved into engagement with the tube 1 by a second air operated piston. In another construction such movements are controlled by a linkage system coupled to the housings 2 and operated by cams secured to a revolving shaft.
