Filed: 1947-07-03
Abstract: 624,333. Brazing; making X-ray electrodes. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 3, 1947, No. 17545. Convention date, July 19, 1941. [Classes 83 (ii) and 83 (iv)] In brazing metals, e.g. nickel-cobalt-iron alloy to copper, a carbonaceous reducing atmosphere is used during heating, and a non- contaminating gas, e.g. nitrogen, hydrogen, or carbon dioxide is used during cooling. An alloy sleeve 13 is placed with a ring of brazing material in a recess of a copper X-ray electrode 14 and supported in a container 24 for electric &c. heating in an oven 22 fed with reducing gas through pipes 35, 36. The reducing gas may comprise nitrogen, hydrogen, carbon dioxide, carbon monoxide or methane, from internal combustion engine exhaust or burning 2.28 to 1 air/town gas. On melting of the brazing material the container 24 is transferred to a gasfilled, water-cooled cooling chamber 44 where a hole in the container base engages a pipe 43 feeding non-reducing gas to displace the reducing gas during cooling. The brazing alloy may be a 50/50 or 70/30 eutectic silver/copper.

Abstract: 624,774. Respiratory apparatus. MINE SAFETY APPLIANCES CO. June 12,1946, No. 17579. Convention date, Nov. 1, 1939. [Class 81 (ii)] A breathing apparatus shown diagrammatically in Fig. 4 comprises a face-piece 1 communicating with a canister by an exhalation tube 4 having a check valve 8 therein, a breathing bag 21 connected to the canister outlet 20, a second bag 23 communicating with the first bag and with the inhalation tube 6 having a check valve 7 therein, and means operable on removal of the canister for cutting off communication between the exhalation tube and bag 21 and the canister, and for connecting the second bag 23 to the exhalation tube whereby connection to the atmosphere is prevented when the canister is removed, said means comprising a slide valve 13 formed with a port 15 which in the position shown registers with a passage 9 connected to exhalation tube 4 which thus communicates with the central tube 16 of canister 17 containing a carbon dioxide-absorbing and oxygen-liberating chemical. The purified air escapes between the canister neck 19 and the reduced lower portion of the slide valve through conduit 20 into bag 21. The said reduced lower portion has a pointed end for piercing the metal foil sealing the canister neck which is provided with a gasket 37 to seat against the flaring lower end of the slide valve cylinder 10. When the canister is removed, the slide valve is urged downwardly by a spring, thereby closing conduit 20 and the communication between passage 9 and the canister, and establishing a communication between passage 9 and bag 23. The latter is provided with a relief valve 24. A spring-operated locking means for the canister, and a saliva-trap adjacent the face-piece are provided.

Abstract: 530,340. Lathes. DEURING, F. R. June 21, 1939, No. 18114. [Class 83 (iii)] In a bar-feed for a hollow-spindle lathe, the bar-stock is gripped by chuck carried by an auxiliary spindle slidable within the main spindle and fed forwards at each reciprocation of the tool turret through a rack and pawl device. The hollow spindle 1 receives the slidable spindle 2 carrying the chuck 3 for gripping the tubular or solid bar-stock 21 and is splined to the chuck by pins 4. Springs 23 tend to draw the chuck rearwardly, as shown, but after a finished work-piece has been cut off by a tool in the slide 22, the turret 18 is advanced to cause a dog 19 thereon to actuate a rod 13 slidable in the working frame 10 and rock a lever 12, thus moving forwards a plunger 8 within the spindle 2. A pawl 9 in the plunger carries with it a collar 6 attached to the spindle 2 and provided with internal and external concentric grooves having a pitch equal to the forward feed required of the bar-stock. A spring plunger 7 in the spindle 1 retains the spindle 2 in the advanced position when the turret is retracted and a spring 20 returns the plunger 8 and pawl 9 to engage the next internal groove. When the bar-stock is used up the plunger 7 and pawl 9 are withdrawn by the operator and the springs 23 return the spindle 2 and chuck for the reception of another stock.

IPC: G21H1/00
Filed: 1963-05-08
Abstract: 1,046,102. Discharge apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 8, 1963 [May 19, 1962], No. 18225/63. Heading H1D. [Also in Division G6] In a method of generating electricity, first and second electrodes 1, 2, Fig. 3, are located respectively in higher and lower pressure zones of an ionized gaseous stream, whereby a potential difference is developed between the two electrodes which arises in major part from the pressure difference, and increases therewith, and with the rate of ionization of the gaseous stream. As shown, gas, e.g. nitrogen, neon or argon, is fed tangentially from pipe 6 through a longitudinal slit in a cylindrical box so that it rotates within the box and escapes through a central hole 9 in one end wall 8 and through a peripheral slot 11 in the other end wall 10. The second electrode 2 is arranged along the axis of the box and the cylindrical wall of the box may constitute the first electrode. Alternatively, the box may be of insulating material and the first electrode may comprise a linear conductor arranged along one generatrix of the box. The gaseous stream flowing through the box is ionized by placing the box in a nuclear reactor, e.g. in the water of a swimming-pool reactor, the peripheral first electrode 1 in the higher pressure zone becoming positive with respect to the axial electrode 2. To obtain high ionization rates, electrode 2 may be provided with a helical coating 19 of a fissionable substance, e.g. uranium oxide. In a further arrangement gas is passed under pressure through a nozzle 18, Fig. 4, into free atmosphere. The gas is subjected to ionizing radiations and inner electrode 1 becomes positive with respect to outer electrode 2.

In a vehicle seat resiliently mounted by means of a hollow piston 10 movable in a vertical cylinder 11 fixed to the vehicle floor and containing liquid to the level 23 above which is an air filled space 24, the cylinder 11 is connected by a pipe to a pump having a by-pass valve by means of which the volume of liquid in the cylinder can be altered to adjust the height of the seat. Wall 26 closing the bottom end of the piston has throttled openings 27, for the passage of liquid, which are closed by a valve plate 38 loaded by a spring 37 when the piston moves upwards and a passage 39 however remains open so that the movement of the piston is braked. To reduce heavy shocks when the piston is in its lowered position a pin 45 is provided on end wall 26 opposite an opening 46, the pin being tapered having a groove 47 or of slightly smaller diameter than the opening so that the liquid can only flow out against a strong throttling resistance. The bars 21 supporting the levers 17, 19 of the seat supporting arm are pivoted to a ring 33 rotatable about the axis of the piston and by means of a catch 35 loaded by a spring 34 engageable with notches 36 in the foot of cylinder 10 the seat may be fixed in any of a number of predetermined positions.

Title: Magneto-optical data storage element
IPC: G11C13/06
Filed: 1967-04-21
Abstract: 1,112,459. Magneto-optical data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. 21 April, 1967 [26 May, 1966], No. 18364/67. Heading H3B. A magnetic storage element of the type which is read by means of a beam of polarized light comprises a storage layer of ferromagnetic material and a layer of transparent ferromagnetic material adjacent thereto, in an exchange coupled relationship. The storage layer may be of nickel-iron alloy and the transparent layer is preferably a semi-conductor such as a rare earth chalcogenide or a ferrimagnetic material. Examples quoted are europium oxide, sulphide, selenide and telluride, and gadolinium iron garnet. The material is maintained below its Curie temperature and, in the case of a ferrimagnetic material, well away from its compensation temperature. Since the layers are both ferromagnetic and are in close contact the remanent magnetization in the storage film induces a magnetization in the same direction in the transparent film. As a result, rotation of the plane of polarization of the incident light beam upon reflection from the storage layer, due to the Kerr effect, is assisted by Faraday rotation when the light passes through the transparent layer. A continuous-film storage matrix is described in which light from a laser is polarized and passed through a light deflector to be directed on to a selected storage region, the reflected light being analysed and directed on to a light detector. The easy axis of the storage film is preferably parallel to the plane of incidence of the polarized light.
