[Also in Division C7] Titanium alloys containing in the annealed condition up to 25% of the beta phase at room temperature are heated to above the beta transus to achieve substantially complete transformation, quenched to partially transform the beta phase to alpha or to a martensitic phase which transforms to alpha on subsequent heating, and worked at a temperature sufficiently below the beta transus to effect spheroidization of the alpha grains. The initial heating, during which working may be effected, may be to a temperature between 50‹ and 100‹ F. above the transus, while quenching should be to at least 30‹ F. below the transus, and is preferably to ambient temperature. At least 50% deformation should then be effected, at a temperature not more than 400‹ F. below the beta transus, and this may be followed by a stress relief anneal at 1350‹ F. for 2 hours in the case of alpha-beta alloys, or at 1650-1675‹ F. for 1 hour followed by 1050-1100‹ F. for 8 hours and air-cooling in the case of alpha or lean beta alloys. Particular alloys referred to are Ti/ 2À5% Sn/5% Al, Ti/5% Al/5% Sn/5% 'Zr, Ti/ 7% Al/12% Zr, Ti/6% Al/4% V, Ti/8% Al/1% Mo/1% V, Ti/5% Al/5% Sn/5% Zr/1% Mo/1% V, while hot-working temperatures were in the range 1750-1875‹ F.

Abstract: 669,098. Fluid-pressure servomotor-control systems. MINING ENGINEERING CO., Ltd. Jan. 26, 1950 [Feb. 8, 1949], No. 3473/49. Class 135 [Also in Group XXX] Conveyer driving apparatus comprises a compressed air motor, transmission means including a fluid coupling, a valve controlling the motor air supply, control means manually operable to provide a temporary air supply for starting and running the motor up to speed, and speed sensitive apparatus on the driven side of the coupling for maintaining the air supply when a predetermined speed is reached and maintained. As shown, compressed air from the inlet 7, Fig. 3, passes a valve 29 to an outlet 28 and a stop valve to a compressed air motor which, through a fluid coupling and worm and pinion reduction gear, drives the conveyer. Air from the inlet 7 passes to a pipe connection 12, Fig. 2, across an adjustably spring-loaded piston valve 23 to a pipe connection 15, thence to a connection 14 and through a passage 36 in a hand-operated rotary cylindrical valve 33 to act on a spring-loaded piston 31 carrying the valve 29. With the stop valve closed, air passes through the rotary valve passages 37, 38, to the lower side of the valve 29 which is therefore held closed by spring 32. To open the valve 29, the valve 33 is rotated against a spring 35 to open the space behind the piston 31 to atmosphere via a port 39, and to supply pressure below the valve via passages 40, 41, 38, the air then being supplied to the motor on opening the stop valve. When the motor has reached its predetermined minimum speed, fly-balls 19, in an inclined two-part ball race 20, 21, splined on the end of the worm-shaft 16, move outwards centrifugally so that the part 21 shifts the valve 23 to close the connection 12 and vent the space behind the piston 31 to atmosphere through connections 14, 15, and passage 25. The valve 33, on being released, is returned by its spring 35 to keep the space behind the piston open to atmosphere via passage 36 and connections 14, 15. If the speed decreases below the minimum, the valve 23 moves to close the valve 29. The motor may be driven at low speed when the valve 29 is closed by air passing through passages 37, 38. The Provisional Specification describes apparatus in which the main piston valve is initially opened against a spring by manually pushing its piston rod and is maintained open, when the minimum speed is reached, by the compressed air.

Abstract: 1,130,711. Semi-conductor devices; printed Circuits. TEXAS INSTRUMENTS Inc. 26 Jan., 1966 [27 Jan., 1965; 26 Feb., 1965], No. 3522/66. Headings H1K and H1R. [Also in Division C7] An electrically conductive connection is made between two conductive regions in a compound semi-conductor body or between one such region and a surface of the body by locally heating the intervening part of the body to vaporize a more volatile element of the compound leaving a hole with a lining of one or more conductive less-volatile elements of the compound constituting the connection. Suitable semi-conductor compounds are specified A III  Bv and An B VI  compounds, A I  B VI , A I  B VII  and rare earth compounds, lead sulphide and mixtures of these compounds with germanium or silicon. While electron bombardment is the preferred form of localized heating, laser beams and electric arcs or sparks are also suitable. The connection may be reinforced by plating gold on a surface in which the hole is to be formed so that it melts and is drawn into the hole. The processes may be used in conjunction with other electron beam techniques, such as the formation of superficial resistors or conductive tracks by bombarding the surface with a lower intensity beam. The resistance of conductive tracks so formed is preferably reduced by electroless plating with nickel, which is preferentially deposited on the electron damaged material. Where both kinds of track are required the bombardment is controlled to make all the tracks resistive, and the surface is masked during a subsequent electroless plating process except for the tracks to be rendered conductive. Alternatively the resistive tracks are formed on completion of the plated conductive tracks. A particularly important use of the described process is the interconnection of circuit elements formed at different levels in a monolith of semiinsulating gallium arsenide.
