Title: Heat-treatment of axle housings
IPC: C21D9/00
Filed: 1973-03-14
Abstract: 1394004 Heat treatment of axle housings MOSKOVSKY AVTOMIBILNY ZAVOD IMENI I A LIKHACHEVA 14 March 1973 12164/73 Heading C7N An automobile driving axle housing is subjected to heat treatment such that the zones of the housing subjected to low stresses in service and located in the side walls of the housing near spring pads are heated to 800-1250‹C for a period such that the zones of the housing subjected to maximum tensile stresses in service and located near spring pads are heated by heat conduction during the heating to a temperature not over 300‹C after which the housing is cooled slowly for at least 180 seconds. The heating period may be up to 180 seconds and the height and length of the zones subjected to low service stresses may be respectively 0.2-0.5 and 1-4 times the housing height in the region of the spring pads and the longitudinal axes of these zones may be located at a height equal to 0.4-0.7 times that of the housing height. The entire housing or those zones subjected to maximum stresses in service may be subjected to a hardening treatment prior to undergoing the heat treatment process described.

Title: Electron beam addressable semiconductor memory
IPC: H01L29/00
Filed: 1972-03-16
Abstract: 1351421 Cathode ray storage tubes GENERAL ELECTRIC CO 16 March 1972 [17 March 1971] 12214/72 Heading H1D The target of a cathode ray storage tube comprises an insulating layer on top of two semi-conductor layers of opposite conducting types forming a junction which is reverse biased. In Fig. 1 the target comprises P and N- type silicon layers 11 and 12 with a silicon dioxide layer 13 and a conductive layer 14 of aluminium. The junction is reverse biased by 5 volt source 18 and a reversible 10 volt bias source 20 is connected between layers 12 and 14. For storing a charge the layer 14 is biased positively to remove negative charges produced when the layer 13 is bombarded by a 10 kV electron beam, thereby leaving a positive charge stored in the insulating layer. In reading, the layer 14 is biased negatively and the beam produces electron-hole pairs in the layer 12; the holes are repelled from charged areas 13 and produce a current in the output resistance 19. The read-out erases the charge image, but the beam current or the irradiation time may be reduced so that the erasure is only partial. Using epitaxially grown or sputtered layers, layers 11-14 may be 100, 10, 0À6 and 0À08 microns thick respectively: if the layers are diffused, the layers 11 and 12 may be 2 and 50 microns thick respectively. Other materials which may be used comprise germanium, silicon nitride, and gold respectively for the semi-conductor, insulating, and conductive layers. The target may comprise a single sheet with 10<SP>6</SP> or more storage sites or several smaller sheets each storing only 10<SP>4</SP> bits of information. In a modification, Fig. 4 (not shown) the conductive layer 14 is omitted and a grid is disposed in front of the target and biased 20 volts positive with respect to layer 12 so that it collects secondary electrons emitted from the surface of insulator 13. During writing the beam has an energy (2 kV) less than the second cross-over energy (2À8 kV) for secondary emission so that the surface of insulator 13 is biased positively by secondary emission, and the charge storage process is the same as before. For reading and erasing the beam energy is made greater (7 kV) than the second cross over energy so that the surface is biased negatively.

Title: A method of making luminescent substances adhere to glass walls
IPC: C09K11/02
Filed: 1939-04-25
Abstract: 528,004. Coating glass. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES, ETABLISSEMENTS CLAUDE-PAZ & SILVA. April 25, 1939, No. 12458. Convention date, March 29. [Class 56] [Also in Groups IV and III] Luminiscent material is suspended in a solution of a cellulose ester in a volatile solvent containing also in dissolved state at least one boric, phosphoric, arsenic, or antimonic acid which is solid at ordinary temperature. The composition is applied to a glass surface and the solvent and cellulose ester are removed. The solvent is removed by evaporation and the cellulose ester and any plasticizer are removed by heating until they decompose. The cellulose ester may be cellulose acetate or nitrate, and the luminescent substance may be zinc silicate. If as a result of the decomposition of the cellulose ester there is a deposit of carbon, this is removed by combustion by heating in presence of air. Heating may be such that the acid component, e.g. boric acid, is softened or fused. The luminescent substance is thus securely fixed to the glass surface.

Filed: 1927-05-11
Abstract: 279,024. Meyer, F., and Spanner, H. J. Oct. 15, 1926, [Convention date]. Addition to 276,303. Vacuum tubes.-The screening arrangements in the incandescent cathode rectifiers of the parent Specification are modified by using as screens between the anodes metal plates electrically connected to the cathode or by dividing the cathode into as many parts as there are anodes, the parts being connected in series or parallel and the individual discharge spaces being separated from one another by the screens. A screen 3, Fig. 2, between anodes 2 may be of insulating-material or insulated metal or may be connected to the cathode which is in two parts one on each side of the screen 3. Disintegration of the cold electrodes is thus prevented, the voltage drop in the rectifier is made small and tendency to internal oscillation on switching off the static fields is avoided. Specifications 274,026 and 275,550 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also metal plates or other auxiliary electrodes adjacent the screens and connected to the cathode for cutting off the static field of electrodes not in operation.

[Class 78 (v).] In self-sustaining gear of the pawl and ratchet type the pawls 122 are pivotally mounted on a flange 86 of the winding drum 68 and are provided with bushings 140 which are urged into engagement with the brake-drum face 142 by coil springs 138. During hoisting this engagement of the bushings with the face holds the pawls out of engagement with the ratchet teeth on the brake drum 130 against the pressure of the springs 138, and no clicking occurs. If the drum 68 endeavours to rotate in the lowering direction when the drive is stopped, the bushings co-operate with the springs 138 to force the pawls into the ratchet teeth. The drum 130 is held by a brakeband 148, the pressure of which is adjusted by varying the distance between its ends by a right and left-handed screw.
