Abstract: 669,533. Lubricating. SOC. POUR LA MISE EN VALEUR DES BREVETS ET PROCEDES D'AEROSOLATION DU DOCTEUR DAUTREBANDE EURATMOS. Nov. 28, 1946 [Nov. 30, 1945], No. 35370/46. Class 12 (iii). In the lubrication of a pneumatic drill or like tool wherein the pressure air is charged with lubricant, means are provided for the atomization of a liquid lubricant, by means of a compressed gas, to obtain a stable suspension of lubricant-in-air, before its introduction into the pressure air. As shown, lubricant in a container 13 is atomized by an air jet device 15 supplied with compressed air via a pipe 12 and into which the lubricant rises by a pipe 16, the resulting cloud of atomized lubricant being directed against an inclined wall 17 of an outlet tube 18, where a film of liquid thereon acts to remove liquid particles from the suspension. A block 20 formed with spaced laminations further serves to remove liquid particles before the suspension passes via a pipe 4<SP>1</SP> to the air line 4 of a pneumatic tool to be lubricated. A sealed supply tank 24 communicating via a pipe 23 to a fixed pipe 21 in the container 13 acts as a bird fountain to maintain a constant level of lubricant therein. In an alternative arrangement the apparatus may be inserted directly in the air line of a tool to be lubricated. Specification 666,393, [Group XXIX], is referred to.

Filed: 1961-10-03
Abstract: 973,420. Friction clutches; change speed control. TWIN DISC CLUTCH CO. Oct. 3, 1961 [March 13, 1961], No. 35645/61. Headings F2C and F2D. In a multiplate friction clutch 28, wherein pressure oil is supplied to cylinder chambers 57, 66 on opposite sides of a reaction piston 16 secured to a driving (or driven) shaft 10 to axially move a cylinder 22 integral with a presser plate 20 into clutch engaging and disengaging positions, cooling oil is supplied to the inner edges of the friction plates through a passage 70 comprising a valve closure ring 74 which when the cylinder 22 is in its disengaged position is held by a shoulder 75 thereon to substantially close the passage 70 outlet thereby minimizing clutch drag and excessive floating of the disengaged plates, and when the cylinder is moved towards, and is in, its engaged position is freed to open the passage 70. Oil leakage past the valve ring 74 is sufficient for lubrication of the friction plates when disengaged, such leakage being increased, if necessary, by grooving the ring (Fig. 5, not shown). In the double clutch 28, 29 shown, for a forward and reverse or change-speed gear, clutch driven members 31, 36 are integral with gears 32, 37. The cylinders 22 are coupled for rotation with the pistons 16 by pins 26. Oil is fed to actuate and cool the clutches through a fixed manifold 41. A pump 81 draws from a sump 80 and delivers oil to a manual distributer valve 85 at a pressure, say 100 p.s.i., regulated by a valve 84 the outlet oil from which is regulated, by a further valve 91, to a lower pressure, say 20 p.s.i., and is continually supplied to the disengaging chambers 66 through pipes 50 and passages 43, 64, and to the inner edges of the friction plates through the passages 70 and arcuate slots 73. Rightward (or leftward) shift of the distributer valve 85, from the midway position, in which both clutches are disengaged, supplies 100 p.s.i. pressure oil to the engaging chamber 57 of the clutch 28 (or 29) through a pipe 49 (or 51) and passages 52, 54, 55, 56, the engaging chamber of the disengaged clutch 29 (or 28) exhausting through a pipe 90 (or 89).

Title: Improvements in machines for manipulating webs
Inventor: WATTS JACK
IPC: B41L5/06
Filed: 1956-11-22
Abstract: 875,141. Typewriters &c. SMITH & SON (ALACRA) Ltd., W. H. Nov. 20, 1957 [Nov. 22, 1956; June 13, 1957], Nos. 35792/56 and 18664/57. Class 100(4) A web manipulating machine such as a typewriting, tabulating, accounting, adding, calculating, or addressing machine has the feed of the webs of stationery or other material such as magnetic tape stopped in predetermined positions under the control of an endless belt, band, chain or like flexible element rotated in synchronism with the stationery feed. As shown applied to an electric typewriter a plastic band 30 is fed over a pin wheel 25 on a shaft 12 which is an extension of the shaft of the platen 10. The belt 30 has notches 44 in its edge spaced to stop the stationery feed at the desired points when a roller 36 of a micro-switch 35 enters the notch and opens the switch. Various modifications of the band are described and it may be used to control more than one web feeding device at a time by having differently shaped or positioned notches. Two programs may be provided on a single tape. The band and web may be fed by a common pin or sprocket drive. Projections may replace the notches in the band. Line spacing. A solenoid 16 is energized to produce line spacing upon the carriage return and acts through levers 17, 18 to draw a pawl 20 over the next tooth of a wheel 15 so that when the solenoid is released again a spring 21 is allowed to advance the wheel 15 one or more line spaces. In use after one line has been typed line spacing occurs which also advances the band 30 so that the roller 36 is withdrawn from the corresponding notch 44 thus closing the micro-switch 35. Another line can now be typed or, as by depressing a special key, a switch can be closed which will cause continuous line spacing to occur until the next notch 44 opens the micro-switch 35 to stop the feed. Specifications 408,125. 707,879, 858,501 and 875,142 are referred to.

Title: Improvements relating to flowmeters
IPC: G01F1/82
Filed: 1959-10-22
Abstract: 887,158. Measuring fluid velocity. GENERAL ELECTRIC CO. Oct. 22, 1959 [Oct. 22, 1958], No. 35830/59. Class 69 (1). A flowmeter has a fluid-accelerating impeller 18, a drive motor 42 for the impeller, a planet gear 88, 92 rotatably carried by the impeller, a resiliently restrained ring gear 94 engaged with the planet gear, and means 64 to sense the movements of the ring gear about its axis. The sun gear 86 is driven from the motor 42 through gearing 44 and magnet assemblies 48, 84 while the ring gear is restrained by a coiled spring 101 and coupled by further magnet assemblies 100, 68 to the means 64 which may be a position telemetering device, such as a synchro. Screws 106 and 110 permit the spring force and zero position of the impeller to be adjusted. Flow straighteners 14 and 16 on either side of the impeller are provided with flow passages 30, 54 and short adjustable vanes 32 to compensate for lack of alignment between the flow passages in the straighteners and the impeller. The ring gear 94 is supported on roller or ballbearings having inner races fixed to a rotating shaft 70 driving the sun gear 86. To eliminate viscosity errors, a cylindrical shroud 128 is provided so that opposite torques due to viscous drag are imposed on the impeller 18 and the supporting member 96 for the ring gear 94. In a modified construction, a disc-like member is mounted on the impeller and adjacent to a plate 82 carrying the magnet assembly 84 so that the viscous drag of the fluid provides an additional driving torque to offset the drag between the outer periphery of the impeller and the meter casing 10. The deflection of the ring gear is measured by a strain gauge. Fluid flow may take place in either direction in both constructions.

Title: Improvements in or relating to clutches
Inventor: PERRY JOHN FREDERICK
IPC: F16D41/02
Filed: 1957-11-20
Abstract: 841,721. Ratchet clutches. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Sept. 29, 1958 [Nov. 20, 1957], No. 36167/57. Class 80 (2). A ratchet clutch having driving and driven surfaces frictionally engaged by spring-biased wedging rollers which can be held in a disengaged position, has one of the surfaces connected to the driving or driven member through an Oldham's coupling, so that an equal load is applied to each of the wedging rollers when the clutch transmits torque. In one form, an externally toothed driving ring 1 freely journalled for rotation upon a driven shaft 2 has a cylindrical clutch surface 4 and contains a spider 3 formed with wedge-shaped pockets 6 in which are located rollers 5. The spider 3 has limited radial play with respect to the driven shaft 2, and is connected thereto by an Oldham's coupling 24, 19, 22 of which the last part is secured to the driven shaft. Springs 8 bias the rollers 5 to engage the cylindrical surface 4 on the driving ring 1 and wedging surfaces 7 in the pockets 6. A ring 9 is mounted for limited rotation upon the spider 3 by screws 12 engaging slots 10 therein, a screw 14 passing through one of the slots carrying a spring 15 attached at one end to a pin 16 on the ring. Pins 17 on the opposite side of the ring 9 enter the wedging pockets 6, the spring 15 biasirg the ring 9 in such a direction that the pins 17 do not engage the rollers 5. If a stationary pawl (not shown) is introduced into the path of a lug 25 on the ring 9 while the clutch is rotating, the ring 9 is turned relatively to the spider 3 so that the pins 17 engage the rollers 5 and move them against the bias of their springs 8 to a position where they are out of engagement with the driving cylindrical surface 4. The clutch is accordingly disengaged. In a modification, Fig. 6 (not shown), the Oldham's coupling is mounted between a driving gear and the cylindrical surface 4.

Abstract: 1,159,079. Phase modulation. HUGHES AIRCRAFT CO. 9 Aug., 1967, No. 36509/67. Heading H3R. In a system for producing a single sideband phase modulated signal, the modulation signal is split into two quadrature components and each is phase modulated into a common carrier by means of respective modulators 43, 45 and the outputs from the two modulators are then added. In order to derive the two quadrature components, the modulation signal is amplitude modulated into a carrier in a balanced modulator 23, and one sideband of the resulting signal is selected by filter 24. The filter output is fed to demodulators 29, 32 to which are also fed quadrature signals at the carrier frequency. The resulting outputs from the two demodulators are the required quadrature components of the modulation signal. The modulation signals are in the form of binary data and the phase modulators 43, 44 are of the type giving 0 or 180 degrees phase shift depending on whether a logical "0" or "1" is being transmitted. In one form of modulator, Fig. 2, the carrier signal is fed to port 71 of a circulator, one arm of which includes a multifactor 78 controlled by the modulation signal. In one binary state of the modulation, the carrier is reflected by the multifactor, and in the other state it is transmitted by it to be reflected at the short circuit 74. If the path difference 2d is 180 degrees then the carrier signal emerges from port 76 with a phase shift of 0 or 180 degrees. In an alternative arrangement Fig. 3 (not shown) a hybrid junction is employed in place of the circulator.

Title: Process for oxidising paraffin or the like and obtaining soaps therefrom
IPC: C11D13/02
Filed: 1920-12-31
Abstract: Fatty acids are produced by treating paraffins, such as paraffin wax, ceresin, or montan wax, with air or oxygen at a pressure of several atmospheres in presence of an alkali, alkaline earth, or alkaline carbonate.  The paraffin is heated to about 150 DEG  C. in a conical vessel fitted with a regulable outlet valve which maintains a pressure of 3-6 atmospheres within the vessel.  Air or oxygen, preferably pre-heated to 120-150 DEG  C., is blown through the paraffin for 12-20 hours.  The air is preferably previously freed from moisture and carbon dioxide. Small quantities of substances rich in oxygen, such as barum peroxide or lead peroxide, may be added as catalysts.  When the oxidation is completed, superheated steam is blown into the vessel and the product healed under pressure with water to effect complete saponification.  According to the Specification as open to inspection under Sect. 91 (3) (a) the oxidation may be performed without the addition of alkali.  This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 12806/84.ALSO:Soaps are produced by treating paraffins, such as paraffin wax, ceresin, or montan wax, with air or oxygen at a pressure of several atmospheres in presence of an alkali, alkaline earth, or alkaline carbonate.

Abstract: 813,455. Microphones and loud-speakers. PICKERING ASSOCIATES Inc. Dec. 21, 1955 [Dec. 21, 1954; Nov. 9, 1955], No. 36672/55. Class 40 (4). In an electrostatic transducer the one, or two, fixed acoustically transparent plates have non- conducting resilient fibres extending from their surface towards the movable plate (diaphragm) and holding it away from the surface of the fixed plate, or plates. As shown, the fixed plates are constituted by two woven galvanized iron wire screens 31, 32 (Fig. 5), each of which is flocked with bristles or fibres 33, 34 of cotton, rayon, fibre glass or other dielectric material. Any well-known flocking technique may be employed. For example, the wire of the screen may be coated with an enamel in a liquid or semiplastic state and fibres of uniform length be sprayed on from a gun, a potential difference of the order of 10,000 volts being maintained between the gun and the screen to cause the fibres to stand on end on the screen, thus forming a nap. The diaphragm assembly 36 consists of two films 37 and 38 (Fig. 7) of mylor polyester resin each having a thickness of 0.00025 inch. To the film 38 is applied (by any well-known metallizing technique) a coat of aluminium 39 of about 1 micro-inch in thickness, which coat lies in contact with the film 37 the edges of which are lapped over the non-aluminized side of film 38. The diaphragm assembly 36 is supported by the free ends of the fibres 33, 34 and is disposed inside a rubber gasket strip 35 which is glued to the free ends of fibres 33 and is preferably no thicker than the length of two fibres plus the thickness of the assembly 36. The resistance of the assembly 36 to displacement and its resonant frequency are determined by the spacing and stiffness of the fibres. The two plates and the diaphragm are mounted as a unit on the frame 20 (Fig. 6) the framework of which is of wood, a rubber rib 30 being placed on the centre beam 24. Leads 41, 42 from screens 31, 32 pass into the groove 26 and through slot 28 to terminal posts (not shown) inside the frame. Lead 40 from the diaphragm is similarly routed in groove 27 and slot 29 to a third terminal post. Suitable circuits for energizing single and multiple-transducer systems are described.
