Title: Improvements in or relating to clutches and means for operating the same
IPC: F16D45/00
Filed: 1934-08-10
Abstract: 445,766. Free wheel clutches. HURD, G., 12, Rhodes Terrace, Beddington Grove, Wallington, and TRIGGS, C. S., 155, Stafford Road, Croydon, both in Surrey. Aug. 10, 1934, No. 23132. [Class 80 (ii)] In a free-wheel clutch for normally driving a gear wheel 25e from an engine shaft 19<a>, the outer cylindrical clutch barrel 108 is integral with the wheel and is movable axially relatively to the inner clutch member 78 which is in splined connection with the shaft, so as to bring a friction face 75 or 75<a>, Fig. 1, or 75<d>, Fig. 13. on the wheel into engagement with a complementary face 75<b> or 75<c>, Fig. 1, or 75<d>, Fig. 13, formed on the member 78, so that the wheel may drive the shaft. The member 78 is journalled in the barrel 108 through a pair of ball bearings 26<a> which are detachably mounted on the member 78, detachable hardened cam seatings 69<a> for the clutch rollers 27<a> being arranged between the bearings. The seatings may be dovetailed in the member 78, as shown in Fig. 2, or they may be in the form of circular plates 69<c>, Fig. 12, which are inserted in non-radial bores in a central flange of the member 78 and are held in position by the inner races of the bearings 26<a> which fit over reduced parts of the plates. Axial movement of the member 78 is prevented by a plate 114, Fig. 1, secured to the shaft 19<a>, or by a thrust bearing 133, Fig. 13. The barrel 108 is rotatable in but compelled to move axially with a control sleeve 116 through ball bearings and a screwed collar 119, the sleeve 116 being mounted in a housing member 76 and being held against rotation by pins engaging slots. The sleeve 116, and thus the barrel 108, is urged to the left by springs 82, which may be adjustable by a screwed collar 131, Fig. 5, and is adapted to be moved to the right by rotation of a ring 121 which is formed with cam projections acting on the collar 119 through pins 81. The ring 121 is mounted in a housing member 124. In the form shown in Fig. 1, the springs 82 tend to engage the friction clutch faces, while in the form shown in Fig. 13 the springs tend to disengage the friction faces. A number of these engine and clutch units may be arranged around a central gear 28f with which the gear 25<e> of each unit meshes, the members 76 and the engine casings A<1> being secured to a common gear casing 3<a>. Specification 427,094, [Group XXXIII], is referred to.

Title: Improvements in or relating to moulding fibrous materials
Inventor: REES JOHN
IPC: B29C45/00
Filed: 1953-08-21
Abstract: 756,745. Moulding fibre resin material. BRISTOL AEROPLANE CO., Ltd. Aug. 23, 1954 [Aug, 21, 1953], No. 23137/53. Class 87(2) Resin bonded fibrous material, e.g. a phenolic resin and asbestos, is moulded in a cavity 31 by injecting the material through an inlet 19 and causing it to leave by an outlet 24 whereby the flow of the material causes the fibres to align themselves, and after a flow adjudged sufficient to align the fibres the outlet is closed and the material in the cavity is allowed to set. The material emerging from the outlet 24 may either fill a recess 23 or may flow past a spring-loaded valve 38 through an outlet 37. The capacity of the recess 23 is such that is fills and builds up a back pressure to stop the flow when the fibres are aligned. The pressure of the spring 40 loading the valve 38 is set according to the moulding pressure required and the heated platens 27, 28 of the press between which the mould is placed are moved inwards and cause a piston 26 to force a charge of material, slightly more than that required, through the cavity 31, overcoming the spring 40 and leaving by the outlet 37. When it is judged that the' material has flowed sufficiently, the pressure on the piston 26 is reduced and the valve 38 closes. Alternatively, fluid pressure may act directly on the material The material is then cured in the cavity as in the first method, the pressure being maintained and the temperature being raised e.g. to 130‹C.-140‹C. for 15-20 minutes. The mould as shown in Fig. 2 is in five parts 14, 15, 16, 21, 22 bolted together and aligned by dowels. When the valve 38 is used the parts 21, 22 are replaced by a part 35. In the example shown the moulded article is a turbine blade.

Title: Improvements in and relating to alkali metal vapour electric discharge devices
IPC: H01J61/35
Filed: 1935-08-21
Abstract: 441,603. Glass manufacture. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 21., 1935, No. 23492. Convention date, Aug. 23, 1934. [Class 56] [See also Group XL] Glass parts of electric discharge devices are protected against attack by hot alkali metal by means of a thin transparent film of a boric oxide glaze fused thereon, after the operation of shaping the device has been performed. In addition to boric oxide (90- 35 per cent) the glaze may contain 4-50 per cent of oxides stabilizing it against weathering or vaporization, such as alkaline earths (barium oxide up to 10 per cent) or preferably alumina. Silica may be present in amounts small enough to be protected from alkali metal attack by the other ingredients. Alkali metal oxides (3-15 per cent) may be added to act as fluxes, to improve transparency and to control the coefficient of expansion. Acid oxides such as phosphorus pentoxide (4 per cent), and fluorine may be present, the latter if cryolite is used as a source of alumina. Compounds of lead, zinc, cadmium, thallium and iron should be avoided. Examples of glaze compositions are given, a prepared formula containing B2O3, 70 per cent; Al2O3, 7 per cent ; BaO, 3 per cent; SrO, 3 per cent ; Na2O, 4 per cent ; K2O, 8 per cent ; and SiO2' 5 per cent. When the boric oxide is used alone, this is preferably applied in the form of boric acid in solution or suspension in methyl alcohol or diethyl carbonate. The coated glass is then heated to about 600‹ C. to convert to boric oxide. A subsequent additional heating to the working temperature of the glass reduces the hygroscopic properties of the boric oxide, possibly by producing combination with the glass. As boric acid is not hygroscopic, the coating is preferably kept in this form, until the glass part is required.

IPC: G11B20/16
Filed: 1955-08-19
Abstract: 839,245. Electronic calculating-apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd., Aug. 17, 1956 [Aug. 19, 1955], No. 23952/55. Class 106 (1). In a binary electronic calculating apparatus (described in Specification 839,241) control signals are produced by a counter which is fed with clock pulses from a magnetic drum, the counter being kept in step with the rotation of the magnetic drum by arranging that the output from the counter upon counting to a predetermined number blocks the input gate to the counter, there being a synchronizing pulse read from the drum at the end of each revolution which unblocks the input gate to the counter so that counting can begin on the next cycle of clock pulses. Part of the apparatus is shown in Fig. 1. The magnetic drum 2 has a number of reading-heads 1 for data storage tracks, a head 5 reading the clock pulses and head 7 reading the synchronization pulse. Sixteen trains of forty clock pulses are detected by head 5 for each drum revolution and are passed to the counter 23, 24 through input gate 22 which is controlled by trigger 26. The counter part 23 counts up to forty and gives an output pulse which is passed to counter part 24. Part 24 counts up to sixteen and then gives an output pulse which is passed to trigger 26 to set it and open input gate 22. In the space between the end of the last word and the beginning of the first word on the drum the synchronization pulse is passed from head 7 to unset trigger 26 and open the gate 22. The number registered in counter part 24 is used, by connections on line 36, to select the word to be read out from the drum.

[Class 59] Material is ground in passing through a series of troughs separated by perforated screens and vibrated by means imparting a circular or elliptical movement in a vertical plane transversely of the troughs so that the material is fed from trough to trough toward the delivery end of the machine. As shown the troughs 1 are given a circular or elliptical motion in a vertical plane and at right angles to the troughs by eccentric oscillatory masses 2 or eccentric drive, the bed being supported on springs 3. Material is fed from a hopper 9 to the first trough where it is ground by bars 6, the fine material passing through screen 4 to the next trough. The screens may vary in mesh and the bars may vary in size, the bars in the last trough in which fine grinding occurs may be of smaller diameter and shorter in length and maintained in separate portions of the trough formed by transverse divisions. The troughs are enclosed by a cover 5 and the troughs may be connected by conduits 11 to a pipe 15 leading to a separator 16, the air being returned by blower 17 to inlet 19. The hopper and pipe connections are formed by flexible connections 10, 18 and 13 respectively. The troughs may be semicircular in shape and the screens may be inclined rearwardly. The screens may be dispensed with and the troughs formed of perforated plates through which the ground material falls, the coarse material passing successively through the troughs until it is discharged through a separate orifice. The troughs may be inclined or may be superposed so that the ground material from one trough falls into the next. When grinding material formed of parts of different hardness is to be ground, the grinding elements may be dispensed with.

Abstract: 835,211. Automatic voltage control systems. BOSCH G.m.b.H., R. July 12, 1957 [July 27, 1956], No. 24263/59. Divided out of 835,210. Class 38 (4). In an automatic voltage regulator for a shunt excited D.C. generator having a transistor in series with the field, the transistor is controlled either directly or over a thermal relay by a Zener diode responsive to generator output voltage. In one embodiment, Fig. 1, a transistor 50 in series with the field F of the generator G is cut-off when the generator voltage rises to the value at which the Zener diode D conducts. In a second embodiment, Fig. 2, the base of the transistor 60 is connected to the collector by a resistor K having a high positive temperature coefficient so that when the Zener diode D conducts and energizes the heater H, the resistor K rises in value so that the transistor 60 is biased to cutoff. In a modification, Fig. 3 (not shown), a resistor with a negative temperature coefficient replaces the resistor K and is connected between base and emitter.
