Abstract: 1,135,632. Transistors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Feb., 1966 [17 Feb., 1965], No. 6385/66. Heading H1K. In an insulated gate field effect transistor, the gate insulating layer has linearly increasing thickness in the source-drain (or drain-source) direction. This enables a constant field intensity to be obtained under the gate electrode in spite of the potential drop (due to source-drain voltage) in the conducting channel. Fig. 1 shows a semi-conductor layer 4 on sourcedrain ohmic electrodes 3, 2 on a glass substrate 1. Gate electrode 6 overlies insulating layer 5 which increases in thickness from 1500Š to 13000Š. The semi-conductor material may consist of intrinsic or extrinsic material such as cadmium sulphide, cadmium selenide, zinc telluride, tin oxide, indium oxide, gallium arsenide or tellurium; the electrodes of gold and the insulating layer of silica or magnesium fluoride. The electrodes may be applied to regions defined by PN junctions. The increasing thickness of insulator may be obtained by deposition through a mask with a slide which is slowly withdrawn.

Abstract: 1,245,560. Decorative coatings. GAF CORP. 23 July, 1968 [3 Aug., 1967], No. 6477/71. Divided out of 1,244,332. Addition to 1,210,103. Heading D1L. A colour pattern in a sheet of textile material is produced by padding with a solution or dispersion of a dyestuff (P) which migrates from cooler to hotter areas under the action of a differential heat pattern followed by passing over a heated patterned die with one surface of the padded material in contact with the die causing the dye (P) to migrate to the hotter areas of the pattern where the surface is dried leaving the remainder of the padded material undried, the resultant padded material then being passed over a heated plain roller with the opposite surface in contact with the roller and the dye (P) which has not migrated under the influence of the patterned die is caused to migrate to the opposite surface of the padded textile material whereby the contrast between the patterned areas of the textile material is increased. The patterned die and roller are heated 300 to 1000‹F which is below the scorch temperature of the textile material. In the figure web 10 passes through bath 42 containing the migrating colour to squeeze rollers at 13 to migrating unit 48 followed by second migrating unit 58 which heats the opposite side of the material to steam unit 25 and roll 26.

Title: Synchroscope
IPC: G01R23/02
Filed: 1943-04-22
Abstract: 565,108. Electric speed - measuring systems. BENDIX AVIATION CORPORATION. April 22, 1943, No. 6516. Convention date, May 23, 1942. [Class 40 (i)] [Also in Group XXXVI] Means for indicating synchronism between two engines, such as aircraft engines, comprises for each engine a generator driving a motor which actuates indicating means, the motors being interconnected by impedance means so that the indicators are oscillated relatively to each other when the speed of one engine changes relatively to the other. The two engines 10, 11 drive shafts 12, 13 carrying permanent magnet rotors 16, 17 of three-phase generators 14, 15. The stator windings 18, 19 are connected with the three-phase stator windings 22, 23 of indicator motors 24, 25. Permanent magnets 28, 29 are driven by the rotors 26, 27 of the motors 24, 25 through connections 30, 31 and are associated with drag cups 32, 33 of non-magnetic metal carried by indicator shafts 34, 35 which are provided with concentric pointers 38, 39. The cups 32, 33 are rotated by eddy currents against the controlling torque of springs 36, 37. Like points of the stator windings 22, 23 are connected by an impedance 42. If the speeds of the engines 10, 11 are equal, the pointers 38, 39 substantially coincide and indicate the speed, since the system maintains its phase and voltage relationships and the rotors 26, 27 run at uniform speed. If one engine speeds up, the system no longer maintains constant phase and voltage relationships and the rotors speed up and slow down once per cycle difference, causing the pointers 38, 39 to oscillate relative to each other. A second impedance may be connected between the same point of the stator winding 22 as the impedance 42 and a second point on the stator winding 23. A third impedance may connect the third point of the winding 23 with a related point of the winding 22. Each impedance may be a resistor or any combination of resistances, capacities and inductances.

[Also in Division B8] in an. apparatus for heat treating and conveying freshly pasted cigars on the heads of which the paste is wet, the freshly pasted cigars 3 on leaving a cigar making machine roll down inclined delivery rails 1, 2 on to a pair of pushers 7, 8  fixed to chains 5, 6 of a conveyer 4 which pushers 7, 8 lift the cigars 3 on to rails 9; 10 and convey them under an infra red heater 16 positioned above their wet ends. The cigars 3 are rolled along the rails 9, 10 with a slight leftward cant to their head ends, the cant being produced by the pushers 7 being of larger diameter than the pushers 8. A guide rail 11 aligns the ends of the cigars. The heat treated cigars 90 fall from the conveyer 4 through an elongated aperture 81 into a funnel 21, Figs. 1, 4, being oriented as they fall by a fixed fulcrum rod 85, and pass thence to a pneumatic conveyer duct 26 under suction from its exit end. The exit end of the duct 26 is coupled to a termination (31, Fig. 7, not shown) connected to a slotted tube (101) the slots of which communicate via an adjustable throttle valve (116) with a suction chamber (121) of a manifold (36). A flap valve (41), on the end of the tube (101) remote from the duct 26, allows the cigars 90 to pass out of the tube (101) whence they are decelerated by the inrush of atmospheric air and finally stopped on hitting a bumper member (50). The cigars 90 then drop on to an endless belt conveyer (133) provided with a plurality of transverse cigar receiving pockets. General arrangement. Fifteen cigar making machines each feeding a heat treating apparatus as above are arranged in three groups of five, the five ducts such as 26 from each group of five being fed into one of three manifolds such as (36), and each of the three manifolds thus delivers cigars 90 to one of three conveyers such as (133).
