Filed: 1953-09-15
Abstract: 758,456. Toothed gearing; friction gearing. CROWSLEY, P. S. Aug. 9, 1954 [Sept. 15, 1953], No. 25461/53. Class 80(1) [Also in Groups VI and XXII] In a lathe accessory wherein a shaft 33 carrying a holder for a milling or other tool is journalled in a member adjustably supported on a slide 34 which may be bolted to the lathe saddle, the shaft 33 is driven from an input shaft 10 through pivotallyconnected rigid shafts 16, 24 having bevel or other gear connections so that the tool holder has a substantially universal movement. The shaft 16 is angularly movable about the axis of shaft 10 and is connected thereto by bevel gearing in a housing 14. Forked brackets 20, 21 formed with respective sleeves surrounding the shafts 16, 24 are pivotally-connected by a spindle 19 carrying a bevel gear which meshes simultaneously with bevel wheels on the shafts 16 and 24 so that the shaft 24 may move angularly both about the spindle 19 and about the axis of shaft 16. A similar pair of forked brackets and bevel gearing interconnect the shafts 24 and 33. The shafts 16, 24 are encased in loose sleeves spacing the forked brackets. In a modification, dispensing with the shaft 10, the shaft 16 is driven through a coaxial motor and changespeed-gear assembly which is pivotally supported about a horizontal axis. In a further modification, the shaft 16 comprises the output shaft of a pivotally-mounted gear box whose input shaft is connected to a driving pulley through a pair of flexible Joints. It is stated that the spindle 19 may carry a pair of bevel wheels meshing separately with wheels on the two shafts 16, 24, and that there may be a similar connection between the shafts 24 and 33. The bevel gearing may be replaced by worm gearing or by friction gearing having wheels of coned or other shape. The mechanism is stated to be applicable to dental drilling machines.

Title: Improvements in or relating to clutch mechanisms
IPC: F16D41/00
Filed: 1963-06-27
Abstract: 1,049,574. Positive clutches. J. MUHLBEYER. June 27, 1963 [June 29, 1962], No. 25691/63. Heading F2C. In a washing machine wherein a washing basket is belt driven through a pulley 17 for both the washing and spin-drying operations by low- and high-speed motors respectively (Fig. 1, not shown), the pulley 17, fast on the high speed motor shaft 5, is driven in the low speed through a pulley 7 which is rotatably mounted on the shaft 5 and positively clutched to the pulley 17 by one or other of two centrifugal masses 24 pivoted on a carrier 14 of the pulley 17 and spring biased to engage a rubber or plastics roller 31, carried at the free end of each mass, with a recess 10 or 11 formed in a hub extension of the pulley 7, the arrangement being such that the clutch remains engaged during the low-speed wash but when, at the end of this operation, the low-speed motor is switched off and the high-speed spin drying commences, the clutch centrifugally disengages at a predetermined speed above that of the low-speed motor which is thereby released to avoid unnecessary wear and noise. Each of the masses 24 comprises two arms 26, 27 spaced by a sleeve at the pivot pin, and at the free end by a rotatable pin 30 which carries the roller 31. To ensure gentle clutch re-arrangement when the high-speed motor slows down, the arm 27 of each mass may be provided with a leaf spring which frictionally engages a surface 38 on the hub 9 to accelerate the pulley hub for synchronized re-engagement with one or other of the rollers 31. During the slow-speed washing process, the washing action operates through reversing means (not shown) to repeatedly reverse its direction of rotation at given intervals of time such that on each reversal the coupled roller 31 rides out of its recess on to and around the cylindrical surface of the hub 9 until the roller carried by the other arm engages the other recess 11 to resume drive in the opposite direction. To this end, the hub 9 may be provided with curved tracks 39, 40 which merge from the recesses 10, 11 on to the cylindrical hub surface permitting the rollers to ride easily in and out of the recesses during reversals in drive. Alternatively, one or each recess may embrace approximately half the hub circumference.

Title: Improvements in or relating to methods of manufacturing semi-conductive devices
IPC: H01L23/10
Filed: 1959-07-29
Abstract: 926,482. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 29, 1959 [Aug. 1, 1958], No. 26025/59. Class 37. A method of making a semi-conductor device comprises alloying an aluminium free metal to a germanium body and subsequently immersing an aluminium or aluminium-containing member in the aluminium free metal while it is molten and reheating the assembly to mix the aluminium with said metal. In one embodiment a pellet 6 of indium containing 0.5% by weight of gallium is alloyed to N-type germanium wafer 3 in the graphite jig 1, 4, by heating at 500‹ C. in hydrogen for 10 minutes in the presence of a trace of hydrogen chloride. After an aluminium wire has been inserted in the molten indium the heating cycle is repeated to form a PN junction. The wire is cut off after cooling and a transistor formed from the body by soldering a gold-coated molybdenum plate to the other face of the wafer with indium to form a second PN junction and soldering nickel strips to the indium pellet and the main part of the wafer. As an alternative, connection to the indium pellet is made by immersing a nickel wire in it with the aluminium wire, the wire being held in position if desired by a guide plug fitting in the jig. A further alternative is to use a nickel, tungsten, or molybdenum wire coated with aluminium, or with a coil of aluminium wound about its lower end, instead of the plain aluminium wire. Specification 803,017 is referred to.

Title: Transport system having a linear motor
IPC: B60L15/00
Filed: 1973-05-31
Abstract: 1434619 Electric motors; control of electric motors JAPANESE NATIONAL RAILWAYS 31 May 1973 [31 May 1972 (3)] 26047/73 Headings H2A and H2J In a transport system comprising stationary coils electrically divided into sections 25-28 and a vehicle 4 carrying field coils which, together with the stationary coils, form a linear motor, the coil sections 25-28 are energized by a control circuit comprising D.C. constant current converters 5, thyristor switches 6, feeder section switches 21-24 and vehicle position detectors 33-36. Only coil sections adjacent the vehicle are energized at any given time and all of the control circuits disclosed operate so as to sequentially energize the coil sections in groups of two or three adjacent coil sections. The control circuit shown in Fig. 8a includes two current converters 5a, 5b, two thyristor switches 6a, 6b, and two sets of feeders 20a-20d and 20e-20h connected respectively to alternate ones of the coil sections through the feeder switches. As the vehicle 4 moves to the left (as shown in the drawing) each position detector turns on the next following feeder switch and turns off the last but one switch, e.g. detector 35 turns on switch 22 and turns off switch 24 so that as the vehicle moves, two coil sections adjacent thereto are simultaneously energized. Each current converter 5 is a thyristor bridge rectifier controlled to give a constant D.C. output. The thyristor switches 6 are thyristor inverters. In a modification, Fig. 9 (not shown), the control circuit includes three current converters 5, three thyristor switches 6 and three sets of feeders connected respectively to every third coil section so that three adjacent coil sections are simultaneously energized as the vehicle moves along. In a further modification, Fig. 10, the thyristor switches are connected between the feeder switches 21-24 and the coil sections. Again, the position detectors are arranged to energize two adjacent coil sections simultaneously as the vehicle moves along. In a modification of the Fig. 10 circuit, Fig. 11 (not shown), there are three current converters and three sets of feeders 20, 21 so that three adjacent coil sections are simultaneously energized. Figs. 12 and 13 (both not shown) illustrate further modifications in which, as the vehicle moves along, respectively two and three coil sections adjacent the vehicle are connected electrically in series for simultaneous energization. Provision is made to alter the switching frequency of the thyristors in the inverters 6 to change the speed of the vehicle.

Title: Method of and apparatus for starting diesel engines with great turning moment
IPC: F01L13/00
Filed: 1930-09-02
Abstract: 369,178. Starting. MOTOREN - FABRIK DEUTZ AKT.-GES., Deutz, Cologne, Germany. Sept. 2, 1930, No. 26155. Convention date, Sept. 2, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 7 (iii) and 7 (v).] In a Diesel engine started by the simultaneous admission of compressed air and fuel, the crank angle during which the compressed air, or the greater part of the compressed air, is admitted is reduced as the speed of the engine increases. In one form, Figs. 1 and 2, air is supplied by a compressor k driven by an auxiliary engine i; and is admitted to the engine cylinder by a valve d actuated by a half-speed cam g. Fuel from the pump h is admitted by an injection nozzle c, and an ignition spiral e is provided. For a six-cylinder four-stroke engine, the cam g, Fig. 2, has a high cam swell extending over about 25‹ and a lower part g<1> extending over about 40‹; on starting, the large cam angle ensures a compressed-air drive in at least one cylinder, but in subsequent strokes the part g<1> is practically ineffective and the admission of air is mainly effected by the part g of the cam. The starting-valve gear and the fuel pump may be controlled by a gear wheel pump l, Figs. 1 and 3, driven by chain gearing and provided on the pressure side with an adjustable throttling member m which may be connected to pressure pipes n, x. The pipe n leads to a pressure cylinder o in which the piston acts on a lever p which gradually reduces the output of the fuel pump h as the fuel pressure rises. The pipe x leads to a cylinder y, Fig. 4, the piston in which is connected to an arm z for adjusting the eccentric pivot q of the lever v of the compressedair valve, so that part of the cam gll becomes ineffective and compressed air is admitted during a decreasing part of the engine stroke. The engine is changed over to normal running by a lever u, Fig. 3, which moves the starting cam g axially and is also connected to a lever w opening a byepass valve v on the pump l.

Title: A method and means for the production of bilaterally-tapered metal strips by cold rolling
IPC: B21H7/10
Filed: 1958-08-14
Abstract: 844,122. Rolling tapered metal strips. MARTIN MILLER A.G. Aug. 14, 1958 (Jan. 10, 1958; Feb. 3, 1958], No. 26159/58. Class 83 (4). A method of making metal strip which is bilaterally tapered in cross-section and intended more particularly for the manufacture of saw and knife blades, comprises cold-rolling a strip of rectangular cross-section between successive pairs of rolls which act on the strip stepwise symmetrical to the centre line of the strip, the inclination of the rolls to the plane of the strip being progressively decreased. Rolling begins at the edges of the work and the rolled regions are moved progressively closes to the centre line of the strip and the angle a enclosed between each two opposite contact zones is reduced with each pair of rolls, the combined taper of the rolls always being greater than that of the strip.

Title: Improvements in or relating to radar antennae
IPC: H01Q3/16
Filed: 1956-08-27
Abstract: 789,140. Aerials. ALBISWERK ZURICH AKT.-GES. Aug. 27, 1956 [Oct. 28, 1955], No. 26201/56. Class 40 (7). Relates to a radar antenna which may perform either a conical scan or a plane scan. The antenna comprises a primary radiator 1 terminating a waveguide 13 and a reflector 2, the two antenna members being arranged for independent movement. To perform a conical scan, the primary radiator is moved in a circle about a first axis 12, whilst the reflector is held stationary, and to perform a linear scan, the primary radiator is held stationary whilst the reflector is oscillated about an axis (horizontal as shown) perpendicular to the first axis. The waveguide is mounted in a universal joint 14 and is coupled through a further universal joint to a disc 15 driven by a motor 16. The primary radiator may thus be moved in a circle about axis 12, and if the inflector is held stationary with its axis of symmetry coincident with axis 12, the antenna performs a conical scan. The angle α between waveguide 13 and axis 12 is 1-1.5 degrees, and the rate of rotation about this axis approximately 1800 revolutions per minute. Reflector 2 is also mounted on joint 14 (but independently of waveguide 13) so as to permit tilting movement about a horizontal axis. For this purpose, the reflector is connected at a point 18 outside the tilting axis through a drive-spring 19 with a crank wheel 20 driven through worm 22 by a motor 21. The arrangement includes springs 23, 24 which are dimensioned so that the resonant frequency of the whole of the tiltable assembly is between 3 and 5 cycles per second. The tilting angle # is approximately 10 degrees. The whole antenna assembly and drive is supported on a pedestal 4 so as to be capable of elevational adjustment about an axis 5 under the control of a motor 9 and azimuthal adjustment about an axis 7 under the control of a motor 8.

Title: Improvements in machines for the manufacture of glass articles
IPC: C03B7/16
Filed: 1935-09-23
Abstract: 463,547. Glass manufacture. PEARSON, T. F. Sept. 23, 1935, No. 26246. [Class 56] A funnel for guiding charges of glass into the parison moulds of a forming-machine, and a baffle for closing the opening of a mould during the counterblowing period, are connected with one another and move with the moulds during the charging and counterblowing periods. The funnel 3, Fig. 1, and the baffle plate 7 are carried by arms 4, 6, respectively, which are integral with one another and swing about a pivot 5 coaxial with the rotating frame 1 on which the parison moulds 2 are mounted. A chain 8, or like flexible element, passes around a sprocket 9 and is connected at its ends to the arm 4, and to an arm 10 that also swings about the pivot 5. When the parts are in the position shown in Fig. 1, the funnel 3 lies over a parison mould, and a stop 14, Fig. 4, is engaged by a stop 13 on an arm 11 which is movable radially on the frame by a fixed cam 12. This arm may be used as a conduit for the air for blowing the glass. The funnel is thus forced to move with the parison mould until the arm 11 is moved inwards by the cam 12, and the stop 13 is withdrawn from the arm 4. A stop on the arm 10, which has been moved backward by the chain, is now engaged by the stop 13 so that the baffle plate 7 lies over the mould opening. The arm 10 is moved forwards with the mould, while the arm 4 moves backwards to its initial position, until the stop 13 is moved inwards away from the arm 10 by the cam 12. The arm 4 is then engaged by another arm 11 and the cycle is repeated.
