Title: High speed motor for example for a dental handpiece
IPC: F01D25/22
Filed: 1963-04-04
Abstract: 1,034,867. Turbines. POWER BRAKE EQUIPMENT CO. April 4, 1963 [April 19, 1962], No. 13432/63. Heading FIT. [Also in Divisions A5 and F2] The invention relates to a dental handpiece of the kind comprising an air driven turbine. The assembly comprises a turbine casing C of open-ended cylindrical form which is formed integrally with a handle portion H, the ends of the casing C being closed by screwed-on cap members 33, 34. Mounted within the casing is the turbine rotor R which comprises a shaft 40 having a flange at its lower end, as seen in Fig. 3, the shaft being bored internally and screwed so as to receive a chuck 41 which is adapted to hold a drill 78. Mounted on the shaft are a rotor disc 62 and two journal members 43, 44 which are of frusto-conical form on their outer surfaces, the parts being secured on the shaft by means of a lock-nut 42. The rotor disc 62 is formed with axially-spaced grooves 62s, also with circumferentially spaced notches 51s (Fig. 4, not shown) around its periphery and with axially-extending holes 51b towards its inner periphery, high pressure air being directed on to the notches 51s to rotate the rotor, the air finally discharging through the holes 51b to the exhaust spaces 68, 69 at the sides of the rotor. The rotor journals 43, 44 co-operate with stator bearing assemblies 29, 30 which comprise bearing members 28, 27 which have frusto-conical surfaces which co-operate with the corresponding surfaces of the rotor journals to form capillary passages 48, 47 to which air under pressure is supplied so as to form a fluid type bearing. The bearing members 28, 27 are received in bearing rings 26, 25 which are supported within the turbine casing C by means of frusto-conical rings 24, 24s, 23, 23s of resilient rubber-like material reinforced with metal wires. The bearing rings 26, 25 are formed at their outer surfaces with circumferential grooves 38, 37 to which air under pressure is supplied through ducts 38, 37 and conduit 55 in the handle portion H, air from the grooves 38, 37 passing through restricted bores 58 in the rings 26, 25 thence through larger bores 59 in the bearing members 28, 27 and so to the capillary passages 48, 47. The air flows from the passages 48, 47 to the turbine exhaust air spaces 68, 69 also to the spaces 71, 70 within the end caps 34, 33 and thence to atmosphere through outlets 73, 72. Air under pressure from the conduit 55 also flows through the duct 51 so as to impinge on the notches 51s formed in the turbine rotor.

Filed: 1931-05-08
Abstract: 376,876. Wired wireless systems. WIRED RADIO, Inc., 60, Broadway, New York, U.S.A. May 8, 1931, No. 13644. Convention date, June 7, 1930. [Class 40 (v).] In a radio-frequency broadcasting system using lighting or power lines the high-frequency currents are impressed on consumers' branch lines only, means being provided for preventing said currents from reaching the main line. Thus in dwellings 8, 9 supplied with light or power from transformers 5, 4 respectively connected to the main line 3 running from the substation 2, radio frequency currents from the transmitter 16, 17, 18 at the substation are applied to the branch lines 6, 7 respectively by branch lines 25, 20 respectively fed from a special high-frequency line 19. Condensers 26, 27, 21, 22 in the high-frequency branch lines 25, 20 isolate them from the power lines, and high-frequency chokes 29, 24 in the lines 6, 7 respectively prevent high-frequency currents from being fed back to the power mains. In the connection shown in dwelling 8 the watt-hour meter 12 aids the choking effect of the choke 29. Specification 338,300, [Class 40 (iii), Telegraphs, Electric], is referred to.

Title: Improvements in photographic printers
IPC: G03B27/72
Filed: 1952-05-29
Abstract: 713,285. Control of photographic printing. RADIO CORPORATION OF AMERICA. May 29, 1952 [June 7, 1951], No. 13696/52. Class 40 (3) In photographic printing apparatus of the type in which a 'scanning spot of light is focused through a transparency on to a sensitive surface the spot of light is made larger than the transparency detail at the surface of the transparency and part of the printing light is diverted to control the intensity of the scanning spot so as to alter the contrast of the printing relatively to that of the transparency except for details within the spot area which remain unaltered. The purpose of this arrangement is to simulate the printing process in which a thin defocused negative is placed in focus with a sharply focused positive transparency and the final positive printed through these. As shown a raster is produced at the screen of a cathode-ray tube 6 by "X" and "Y" deflection coils 14. The spot is then focussed on the screen of the tube by a coil 10 when it is defocussed on to the surface of the transparency 20 by a lens 18. Alternatively, a larger spot produced on the end of the tube may be focused on to the transparency. The plane of the transparency is then focused on to the printing surface 38 by a lens 37. A partially reflecting mirror 26 diverts part of the printing light to a photo-cell 28 which through a non-linear circuit 32 (v.i.) modifies the grid-cathode difference potential of the cathode-ray tube altering the relative contrast of the print and the transparency. Non-linear circuit, Fig. 2.-The output signal <SP>e</SP>c of the photo-electric cell is applied to the grid of an amplifying valve 42 which feeds the cathode-ray tube grid. A resistor 56 connected in the grid line of valve 42 has the grid end shunted by diodes 49, 50, 51, the cathodes of which are differently biased by potentiometers 45, 46, 47 so that as the input signals increase the diodes conduct one after the other causing an increasing voltage drop in resistor 56 so that a lower and lower proportion of the input signal is applied to the grid of the cathode-ray tube as the input signal rises.

Title: Grease composition
Filed: 1956-05-03
Abstract: A lubricating grease composition comprises an oleaginous liquid thickened with a combination of a lithium soap and an initially hydrophilic clay.  The oleaginous liquid may be mineral oil, hydrogenated fish oil, animal oil, vegetable oil, fluorocarbon oil, e.g. a perfluorinated petroleum oil, a synthetic lubricating oil prepared by cracking and polymerizing products of the Fischer-Tropsch process, or other synthetic lubricating oil, e.g. silicones, aliphatic ethers, aromatic acid esters, aliphatic mono- and dicarboxylic acid esters, phosphorus acid esters and halogenated aromatic compounds.  The lithium soap may be derived from a fat or fatty acid containing a straight chain of at least 8 carbon atoms. The clays are naturally occurring chemically unmodified clays in purified form, and are complex inorganic silicates containing cation-exchangeable groups, suitable clays being attapulgite, illite, saponite, sepiolite, biotite, vermiculite, bentonite, hectorite and zeolites.  These may be used directly in their inherent hydrophilic form.  Optional ingredients mentioned are anti-wear agents and antioxidants.  The greases are preferably blended at 200-350 DEG  F. under super-atmospheric pressure.  In examples, greases are prepared from (i) mineral oil, colloidal attapulgite, hydrogenated soybean fatty acids, lithium hydroxide and water; and (ii) iso-octyl adipate, colloidal attapulgite, and lithium stearate at 300 DEG  F. and a pressure of 700 lb. per sq. in.  Specification 759,304 is referred to.ALSO:A grease composition comprises a liquid polyorganosiloxane thickened with a combination of a lithium soap and an initially hydrophilic clay.

Abstract: 337,758. Reik, H. Feb. 26, 1929, [Convention date]. Void [Published under Sect. 91 of the Acts]. Variable-speed gearing comprises joined gears 2, 2<1>, slidably splined on the driven shaft 1 and joined gears 4, 4<1> slidably splined on lay shaft 5. When the four gears are moved together to the left so that a clutch 6 on pinion 9 on driving- shaft 8 is engaged, a direct drive is effected. When the four gears are moved together to the right so that a clutch 7 on a loose gear 12 is engaged, a fourth speed is obtained through train 9 - - 12. When the gears 4, 4<11> only are moved to left and right, two intermediate speeds are effected. The gear box is thus shortened. The control lever 3 may engage two or one selector forks or fork alternatively. In another arrangement, which is stated to yield six speeds, there is added to a three-speed gear a pair of gears imparting an overdrive to the lay shaft.
