Abstract: 507,217. Coating surface. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) Dec. 10, 1937, No. 34202. [Class 95] In a method of applying- a coating of liquid to a workpiece of sheet material, e.g. a coating of ink to the edges of shoe upper parts, use is made of a machine comprising a rotating roll, an absorbent belt wrapped around a portion of the roll, and a second rotating roll, the belt passing between the two rolls, and the workpiece is introduced between the belt and the first-mentioned roll so that one face thereof is held, by the belt, against the periphery of the roll to prevent access of liquid to that face, the liquid being wrung from the belt, by the action of the rolls, and applied to the workpiece. The machine shown comprises an endless belt 10 having an absorbent layer 12 and a reinforced rubber layer 14 provided with edge flanges 16. This belt is wrapped around part of the driven, smooth, work-engaging roll 20 and the adjustable wringer roll 36, and its tension may be adjusted by actuating the hand lever 50. Work 84, 86, laid upon the part 70 of the belt 10, has one of its faces held against and protected by the surface of the roll 20, while, on reaching the bite of the rolls 20, 36, ink is squeezed out of the layer 12 and is applied to the other face, and to all the edges of the work, which is then stripped by pivoted fingers 110, and guided up to a table 120. Ink is dropped upon the layer 12 in such quantity that the latter feels substantially dry to the touch. To prevent soiling of the one face of the work; a removable, adjustable, V-shaped scraper 130, of leather soaked in paraffin wax, and a rotary tufted cleaner 164 are provided, and excess ink is collected from the end faces of the roll 20 by removable, adjustable tubes 170, and discharged on to the layer 12.

IPC: F16D43/12
Filed: 1960-10-06
Abstract: 920,888. Friction clutches. AUTOMOTIVE PRODUCTS CO. Ltd. Sept. 22, 1961 [Oct. 6, 1960], No. 34320/60. Class 80 (2). A centrifugally operated disc clutch is provided with two sets of control springs 23, 24 between the pressure plate 12 and reaction plate 14, the springs 23 being relatively weak and bearing directly against the reaction plate 14, while the springs 24, which are preferably stronger and also precompressed, bear against sleeves 27 with flanges normally clear of the reaction plate. As the centrifugal members move the pressure plate 12 into engagement with the driven disc 13 only the weak springs 23 are effective to give a light clutch engagement sufficient for small and slow vehicle movements as required for parking. As the clearance between the clutch elements is taken up the flanges on sleeves 27 engage the reaction plate 14 to allow the stronger springs 24 also to become progressively effective, with an initial abrupt increase of resistance, and an appreciable increase of engine speed is then necessary to produce further clutch engagement.

Abstract: 1,083,881. Transistors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 27, 1964 [Aug. 30, 1963], No. 35121/64. Heading H1K. A field effect transistor with a variable-mu characteristic is provided by constructing the gate electrode region so that a small portion of its transverse dimension provides a mutual conductance effect different from that provided by the rest of the gate electrode. The invention is applicable to transistors operating in the depletion mode where the matching region provides a retarded controlled interruption effect which becomes effective after the main portion of the current path has been closed off and to operation in the enhancement mode wherein an advanced enhancement effect operates before the main path has opened. The special effect of the matching region may be produced by varying the effective width of the gate electrode in one portion or the thickness or the resistivity of the associated semi-conductor portion, or electrode positioning, or providing a small gap in the gate electrode which becomes effective for cut-off only at high gate voltages, or by varying the thickness of the insulation of the gate electrode, or by using material with different contact potential for part of the gate electrode. Fig. 1 shows an N-type silicon layer covered by source and drain electrodes 3 and 4 separated by a 20 Á gap which is covered by an insulating layer and metallic layer 6 to form the gate electrode. The metallic layer is cut away to provide a thin portion 7 which constitutes the matching region. Instead of thin portion 7, a gap of a few microns may be provided in the gate electrode which is bridged by a conductor and has a similar effect. In another embodiment, the source, drain and gate electrodes are annular in form, and a sector of the gate electrode is provided with a thicker insulator layer than the remainder of the gate electrode. Two or more gate electrodes may be provided some of which may act as a screen. Cadmium sulphide or germanium may be used as semi-conductor and may be in the form of layers on intrinsic silicon or insulating substrates and may form part of solid circuit arrangements. The invention is applicable to insulated gate or PN junction field effect transistors.
