Filed: 1945-09-17
Abstract: 613,029. Gear-cutting. MILLER, E. W., and FELLOWS GEAR SHAPER CO. Sept. 17, 1945, No. 23986. [Class 83 (iii)] A machine for finishing gears and similar curved faces comprises a rotatable work-holder and cutting tool disposed on a supporting structure such that the tool will generate a curved surface on a workpiece in consequence of relative rolling movements between the tool and work-holder, a wheel or rocker in torque-transmitting connection with the work-holder, a slide mounted for linear movement on the supporting structure in non-slip rolling connection with said wheel or rocker, an abutment or abutments mounted on the supporting structure in position to be engaged by the slide, and means for effecting relative displacements between the work-holder and slide and between the cutting tool and abutment or abutments in a direction transverse to the axis of rotation of the workholder. The machine in general construction is the " Fellows " type having a pair of independently driven grinding discs 16, 17, Fig. 1, arranged on a " stool " 15 over which the workpiece 30 is passed in a " rack-and-pinion " generating motion. The work is carried between centres in a tailstock 29, the axis of which is at right angles to and is carried by a reciprocating beam 13. A fluid piston 31 moving within a cylinder formed in the stationary part of the machine effects the reciprocation. The workpiece is arranged to rotate in timed relation with the movements of the beam by connecting it through a linkwork 29, 39, 37 to a drum 35 rotatable on an axis 36, Fig. 2, carried by the beam, and steel tapes 40, 41 passing around the drum and anchored thereto, the other ends of the tapes being connected to a slide 42 carried in a guideway secured to a stationary part of the machine frame. The slide comes against adjustable abutments 51, 52 at each end, the whole arrangement serving as a lost-motion device to position the work relative to the grinding discs. A torque-producing device 66, 67, Fig. 3, is connected to the drum spindle and is adapted, selectively, to hold the slide 42 against either the right- or left-hand stop, thus determining whether a tooth is ground from root to tip or vice versa. The stops may be adjusted to vary the amount of cut and this may be effected by hand or automatically. In place of the drum and steel tapes, a pinion may be substituted engaging a rack carried by the slide 42, Figs. 5 and 6 (not shown). Specification 554, 115 is referred to.

Abstract: 443,213. Operating and locking lift doors ; hinges. SCOTT, M. D., 75, Clerkenwell Road, and WINSLADE, M. L., 26, Ashwater Road, Lee, both in London. Aug. 20, 1934, No. 24019. [Classes 65 (i) and 65 (ii)] [See also Group XXX] A pair of doors, particularly for a lift shaft, mounted for movement about vertical axes and biassed to return to the closed position, are interconnected to move in unison, and a dashpot, to check the closing movement, is included in a mechanical linkage coupled at its ends to the two doors, this linkage preferably also serving as the means interconnecting the doors. In the arrangement shown, the doors A, B are fixed to vertical rods 2 which pass through bearings in the lintel and are bored at their lower ends to receive pivot pins fixed in bosses formed with cam surfaces engaging corresponding surfaces on the lower ends of the rods so that the doors rise when opened and are thus self-closing. Cranks 7 fixed to the upper ends of the rods 2 are connected by a rod 11 carrying the piston of a check 13, the rod 11 passing completely through the check cylinder, which is pivoted on the lintel by means allowing limited vertical and lateral movement to accommodate movements of the rod 11 ; the cylinder has holes in one end to allow free passage of the air, a hole 21 near the other end allowing free passage of air when the piston is moving towards this end until it covers this hole 21, and a valve 22 giving a throttled passage to check the rest of the movement of the piston towards this end. The rod 11 also carries a cam 39 which opens a switch 40 in the lift motor circuit except when the doors are closed. The doors are prevented from opening when the lift cage is not present by bolts 30 which are withdrawn, on arrival of the cage, by chain-and-cam 34 on shaft 35 operated through roller-and-crank 36 by an arm on the cage.

IPC: H01L29/00
Filed: 1964-06-11
Abstract: 1,010,404. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. June 11, 1964, No. 24245/64. Heading H1K. In a field effect transistor a diffused region of one conductivity type in a body of the opposite conductivity type is covered by an epitaxial layer of semi-conductor of the opposite conductivity type. As shown, Fig. 2, a plurality of field effect transistors are produced by epitaxially depositing a layer 1 of N-type silicon on to a wafer 2 of N-type silicon of lower resistivtiy. A plurality of P-type regions 3 (shown in section) are produced in the epitaxial layer by masking with an oxide layer and diffusing-in boron. Each P-type region 3 completely surrounds a small rectangular region 4 of N-type material. As shown, Fig. 5, a layer 5 of N-type silicon is epitaxially deposited on layer 1 and a second boron diffusion produces P-type regions 6 overlying and contacting the first diffused regions. The rectangular N-type region 7 surrounded by region 6 is larger than region 4 and an ohmic contact 9 is produced by diffusing phosphorus into this region. Aluminium electrodes are deposited on part 8 of region 6 and on region 9 and are alloyed to the wafer. The wafer is then divided into individual units which may be mounted on a header or in a thin film circuit, region 4 forming the channel, region 6 (and 3) the gate, wafer 2 the source and contact 9 the drain. The conductivity types of the regions may be reversed and the semi-conductor material may be germanium, deposited silicon oxide being used for the diffusion masks.

Title: Improvements relating to the control of control reservoir charging in compressed fluid braking apparatus of the graduated release kind
IPC: B60T15/30
Filed: 1956-08-08
Abstract: 803,685. Fluid pressure brakes. WESTING- HOUSE AIR BRAKE CO. Aug. 8, 1956 [Aug. 9, 1955], No. 24325/56. Class 103 (1). A quick service valve device for fluid pressure brakes, particularly for railway vehicles, is so adapted that in response to a slight reduction of pressure in the brake pipe 3, below its fully charged value, it closes the charging communication to the control reservoir 4 and only subsequently performs its usual function of allowing a local withdrawal of compressed fluid from the brake pipe to intensify locally the reduction in brake pipe pressure. According to the invention, when the quick service valve 84 is in its quick service position, the free end thereof laps the passage 51, closing it off from the passage 89 and thereby closing the previously defined ,control reservoir slow charge communication so as to sever promptly and positively all existing connection between the control reservoir and brake pipe. By this arrangement back flow of compressed fluid from the control reservoir 4 and chamber 16 of the service valve device 8 to the brake pipe is negligible. Only after passage 51 has been lapped, does the quick service valve 84 perform its usual function in that in the quick service position compressed fluid is released locally from the brake pipe 3 at a rapid rate through passage 37, chamber 83, cavity 91 and passage 92 to quick service volume 93.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/39
Filed: 1950-10-05
Abstract: 686,345. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd., and HILL, R. T. J. July 19, 1951 (Oct. 5, 1950], No. 24389/50. Class 39(i) A method of making a mosaic screen for a storage cathode ray tube comprises pressing a metal mesh consisting of fine wire of a metal harder than that of a base plate against the surface of the metal base plate so that the mesh is pressed into the surface and adheres intimately to the plate everywhere over the region where small areas of a different material are to be formed on the plate, applying the different material to the region over the mesh, and peeling off the mesh from the plate to leave on the plate small areas of the different material defined by the apertures of the mesh. The base plate may be of aluminium and may be covered with a mesh of stainless steel wire 0.035 mm. diameter containing 200 wires to the inch; on top of the mesh is placed a steel plate and the sandwich is passed through a pair of set rollers whose separation is equal to the combined thickness of the base plate and the steel plate. The steel plate is then removed and the aluminium base plate with the mesh embedded in its surface may be dipped for about 2 minutes in caustic soda to etch away any aluminium which may have flowed over the top of the mesh. The surface may then be painted with a binder, such as phosphoric acid, and a layer of fine magnesia powder or a phosphor may be sprayed or dusted on. The assembly may then be baked and the mesh peeled off. The base plate, with the mesh affixed to it, may be pressed into a part-spherical shape before the surface material is applied to it. The surface material may be applied as a plurality of layers of different material, for example a layer of insulating material followed by a layer of conductive or photo-electric material. The material may be applied by evaporation or electro-chemical material.

Title: Improvements in and relating to voltage regulating devices for dynamo-electric machines
IPC: H02P9/24
Filed: 1929-08-10
Abstract: 317,094. Lorenz Akt.-Ges., C. Aug. 11, 1928, [Convention date]. Exciting; regulation of exciting machines.-In modifications of the regulating system described below, the regulator controls the field circuit of an auxiliary exciter and a small battery is provided for preventing de-excitation of the auxiliary machine. Instead of employing an auxiliary exciter directly in the field circuit of the main machine, an additional field winding or additional field poles may be provided on the main machine and separately excited from the auxiliary machine. The auxiliary exciter can be supplied with excitation current from a battery brought into circuit by one or more relays energized by the regulator for increasing the effectiveness of the regulation. The voltage regulation system has an additional regulating resistance, for example in the field circuit of a generator, the resistance being automatically controlled by a reversible motor in dependence upon the difference in period of the opening and closing movements of the regulator contacts. In one arrangement, Fig. 3, a self-excited generator 2 is provided with field resistances 5, 6. The resistance 5 is periodically short-circuited by contacts 8, 9 which are operated by a relay having a constant voltage winding 11 and a winding 10 fed from a separate alternating- current source 7. The frequency of the source 7 determines the difference between the opening and closing periods of the contacts 8, 9 which energize a relay 12. The relay 12 operates contacts 13, 14, 15 to energize a reversible motor 17. The closing periods of contacts 13, 14 or 13, 15 are made equal to those of the opening and closing of contacts 8, 9, so that when either the opening or the closing period of the contacts 8, 9 is lengthened due to overload &c., the motor 17 is operated in one direction or the other to vary the resistance 6.
