Title: Improvements in the manufacture and production of viscous oils
IPC: C10M159/04
Filed: 1929-01-21
Abstract: 322,935. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 21, 1929. Addition to 305,553. Mineral and tar oils; lubricants.-Hydrocarbons oils are made sufficiently viscous for lubricating or insulating purposes by adding products of the process of the parent Specification which are more viscous than is the desired lubricant. In an example, a spindle oil, obtained by destructively hydrogenating lignite, removing benzines and middle oils and deparaffining and purifying, is subjected in the coherent liquid phase to electric current of about 5000 volts and 2000 cycles for 44 hrs. 5-40 per cent is then added to untreated oil. Still thicker products may be obtained by conducting the electrical treatment at varied temperatures.

Title: Improvements in or relating to television receivers
IPC: H04N5/44
Filed: 1950-01-27
Abstract: 672,043. Television. HAYNES, H. F. Jan. 23, 1951 [Jan. 27, 1950], No. 2239/50. Class 40 (iii). A television receiver indicating device which is arranged normally to be energized when the receiver is switched on is prevented from being energized when picture or synchronizing signals are being received. As shown in the drawing the indicator device, which comprises a neon lamp 13, is connected in series with a high resistance 14 between the H.T. supply line 15 and the anode of the normal synchronizing signal separator valve 10 to the control grid of which the video signal (with positively-going synchronizing signals) is applied. During normal operation of the receiver, i.e. when television signals are being received, the anode potential of valve 10 is such that the p.d. across the neon lamp is insufficient to cause it to "strike." When the television signals cease, however, the mean potential of the control grid rises and the resulting drop in anode potential renders the p.d. across the neon sufficient to cause it to "strike" Instead of employing a neon lamp as the indicating device other indicating devices, controlled, e.g. by a balanced relay responsive to the change in potential caused by the (presence or absence of) television signals, may be employed.

Filed: 1951-01-31
Abstract: 678,254. Coiling. SPUHL AKT.-GES. Jan. 31, 1951 [Sept. 21, 1950], No. 2431/51. Class 83 (iv). Sharing adjuncts.-A mechanism for moving upholstery springs from a coiling machine to end knotting means comprises telescopic arms I-VI, with grippers 14, pivoted on a loose bush 7 and oscillated vertically in slots in a frame 6 by cams 8,' 9. The latter are keyed to a shaft 4 oscillated from a cam 24. The frame 6 is braked by a spring- block 29 and is rotated when a pin 21 on the cam 8 engages a projection on the frame 6. A finger x controls the movement of the gripper 14 towards and away from the machines in conjunction with a spring 16. In operation, when cam 24 moves the crank 5, A-B, an arm 1 is moved towards a coil winding machine and the mechanism x pulls gripper 14 back. When the wire is cut, the mechanism x releases grippers 14 which engages the spring. During rotation of the cam from D-G the first spring is wound by a shunt guide machine, not shown, the arms remaining stationary. The cam moves G-F to lift the spring from the winding-machine. On moving F-E the pin 21 engages and moves the casing 6 to position the spring opposite the first knotting-machine, then, in sequence, the spring is moved sideways into the first knotting- machine, is knotted and moved out of the knotting-machine. When the cam again moves F-E the spring is moved to a second knotting- machine. On the next actuation of the cam F-E the knotted spring is moved to a collecting shoot. The gripper may be formed with the stationary jaws resiliently mounted on the carrying arms.

Abstract: 1,170,682. Semi-conductor devices. GENERAL ELECTRIC CO. 18 Jan., 1967 [1 March, 1966], No. 2767/67. Heading H1K. In a device comprising a semi-conductor body with an oxide layer on its surface a layer of silicon nitride is provided over at least part of the oxide layer. At typical planar transistor of this type is made in conventional manner except that another layer of silicon nitride is deposited over the masking oxide before etching to form the aperture through which the base zone is diffused. In a modification of this method nitride is again deposited over the oxide before formation of the emitter zone diffusion aperture and before deposition of the aluminium emitter electrode by evaporation. In both cases the body of the wafer is of phosphorus doped silicon, boron and phosphorus respectively being diffused in to form the base and emitter zones. The nitride is deposited from a mixture of silane and ammonia. In an insulated gate field effect transistor embodying the invention (Fig. 4) the oxide layer 28 is formed thinner over the channel and the nitride layer deposited over the entire oxide surface. The gate electrode 30 of vapour deposited aluminium and other electrodes 31 are then provided. Also described is a capacitor with a dielectric consisting of superposed layers of silicon dioxide and nitride between a silicon substrate and an aluminium layer consituting the electrodes.

Title: Improvements connected with switching arrangements for the field control of d.c. electric motors
IPC: H02P7/298
Filed: 1946-01-29
Abstract: 607,252. Control of D.C. motors. WHEELER, H. D., and MOSSAY, P. A. H. Jan. 29, 1946, No. 2893. [Class 38 (iii)] Varying field.-The speed of a shunt-wound or lightly-compounded direct-current motor is controlled by varying its shunt field excitation and means are provided to afford an intermediate stage of medium excitation when changing from full to weak field and vice versa. Full field obtains when a switch SW4 is closed, a relay 1 being energized to short-circuit both a resistor R in series with the field winding SH, and the coil of a time-delay relay 2, thereby open-circuiting a diverter resistance D. When the switch SW4 is opened the relay 1 is deenergized to place the resistor R in series with the winding SH, the connection of the resistor D across the field winding being delayed. Similarly, when the switch SW4 is re-closed, the resistor R is first short-circuited and later the diverter resistance is removed. In a modification, a resistance is connected in parallel with the series resistor R before the diverting resistance is removed when changing from weak to full shunt field.

Abstract: 427,579. Brick making plant. DRYSDALE, J., Balmaha, Adel Lane, Adel, near Leeds. Jan. 29, 1934, No. 2914. [Class 87 (ii)] [See also Group X] To facilitate the operating of a brick-making plant, presses 6 are located at the end of the kiln 1 and have associated therewith a track 5 whereby loaded trucks can be fed to a transfer car 8 running upon a main track 4 through the kiln, and empty trucks, brought back by the car 8, can be fed to the presses. These may be arranged in pairs on both sides of the track 4 and one or more tracks 5 may be provided in closed loops adjoining the track 4. Light rail tracks 7 may pass between the presses and connect the tracks 4, 5. Empty trucks on the tracks 5 can be fed between the presses, loaded from both sides and run on from both sides of the track 4 to aligned transverse tracks 9 mounted on the car 8, there being at least one more track 9 than the number of tracks 7 on one side of the track 4. Thus, one track 9 is left empty and when the car is moved to the wickets of a kiln, the empty track 9 can be utilized to receive empty trucks from the kiln before discharging loaded trucks. Such discharge empties a track 9 which can be used in the same way and this sequence continues until all the tracks 9 are full of empty trucks when the car is returned and the empty trucks run on to the tracks 5. The car 8 may be self-propelled or hand or power driven. The tracks are so arranged that loaded trucks will run by gravity from the presses to the car and from it to the kilns and the trucks may be controlled by axle grips.

Title: Indirectly heated cathode
IPC: H01J1/20
Filed: 1933-02-01
Abstract: 414,375. Thermionic cathodes. LOEWE, S., 10, Wiesenweg, Steglitz, Berlin. Feb. 1, 1933, No. 3060. Convention date, Feb. 2, 1932. [Class 39 (i).] An indirectly-heated cathode of the kind in which the emissive surface is prepared by exposing an equipotential surface to metal vapour is so constructed that any emission due to deposit of emissive metal on those parts of the insulating tube not covered by the equipotential surface, and any leakage between the heater filament and the equipotential surface due to such deposit are prevented by means other than those involving coating the ends of the insulating tube with a rough, non-emissive coating. In one construction, screens are so disposed as to prevent deposit on the ends 6 of the insulating tube. In the form shown the equipotential layer consists of two metal tubes 2, 6, which are slipped one over the other, so that the outer tube 2 projects beyond the inner tube 6 at each end, leaving a small pocket 7 into which vapour will not enter. Alternatively the equipotential layer may be in the form of a tube having inwardly projecting resilient ribs. In another construction, the ends of the insulating tube are coated with graphite, which, in addition to fulfilling the objects of the invention, cools the ends of the insulating tube. In another method, the equipotential surface of the cathode of a thermionic valve is shorter than the insulating tube but longer than the grid, which, in turn, is longer than the anode. The activating barium vapour, which may be released from a capsule in the anode, is deposited mainly on the middle of the equipotential surface, whilst any which is deposited on the insulating tube is removed by intensive heating at these points obtained by making the heater coil of closer pitch here than elsewhere. Reference has been directed by the Comptroller to Specification 375,481.
