Title: Spindle bearing
IPC: D01H7/12
Filed: 1961-09-19
Abstract: 928,670. Bearings for spinning-spindles. WURTTEMBERGISCHE SPINDELFABRIK G.m.b.H. Sept. 19, 1961 [Oct. 10, 1960], No. 33575/61. Class 120 (2). [Also in Group XXXIV] To centre a foot-bearing 1, for a belt-driven spinning or spindle supported by separate neck and foot bearings on a common housing 9, it is surrounded by a damping and centering socket 3 arranged to tilt about upper and lower edges, the socket being arranged within further damping means, e.g. on an oil-damping coil 10. The upper tilting-edge may be provided by a flange 8 at the top of the socket bearing on the inside of the housing or on a spring-ring fitted inside the housing; or by an interchangeable or elastic spring-ring between the socket and the housing resting or not on a locking ring. The lower tilting edge 12 may be provided by resting the socket on the flat surface of a raised portion of a cup-shaped member 7, which may be such as to provide the edge 12 as near as may be desired to the axis of the socket. In another form, Fig. 3, not shown the socket 3 rests inside the cup of member 7; also, the outer flanged portions of the member 7 may be inclined to rest on a seating on housing 9. A spring may bear directly, or through a ring, on the top of socket 3. The bearing 1 may be held in place by a projection 4 of a spring-ring 5, and a further spring-ring 11 positions the coil 10 which may be formed of nesting tubes turned over at their upper edges to seal off the oil. The coil may be replaced by a member of foamed plastic material with oil in its cavities.

Title: Improvements relating to the heat treatment of castings of aluminium alloys
IPC: C22F1/057
Filed: 1921-12-14
Abstract: 173,746. Archer, R. S., and Jeffries, Z. Jan. 4, 1921, [Convention date]. Alloys.-Castings of aluminium alloys containing from 2 to 5 per cent of copper are improved by heat-treatment. The treatment is applicable also to aluminium-copper alloys containing silicon either in the small amounts occurring as impurities in commercial aluminium or in subtantial amounts, e.g. 3 to 15 per cent. In order to avoid as far as possible the formation of crystalling needles of FeAl, due to the presence of iron in commercial aluminium silicon is added where necessary to ensure an excess of silicon some of which combines with the iron thereby reducing the quantity of FeAl3 formed. Zinc and/or magnesium may also be added to the alloys to be treated. In the preparation of the alloys the temperature is kept as low as possible, preferably below 750‹ C. The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of aluminium alloys containing silicon without copper and states that alkali metals may be added to the alloys. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 19282/05 and 159,852 [both in Class 72, Iron, &c.]

Filed: 1937-12-13
Abstract: 492,081. Gas turbines. AKTIEBOLAGET MILO. Dec. 13, 1937, No. 34513. Convention date, Dec. 15, 1936. [Class 110 (iii)] The working medium in the high-pressure stage of a gas turbine contains an excess of air and the medium is re-heated between stages by burning fresh fuel-gas with the excess air. In the example shown, a fuel-gas generator 19 is supplied with air compressed in a pump 4, pre-heated in a regenerator 17 and controlled in accordance with the load by a valve 23. Fuel-gas and compressed air are led to a combustion chamber 12 which supplies the working medium to a high-pressure stage turbine 1. The exhaust from turbine 1 passes through are-heater 15 to the stage turbine 2 and fuel-gas admitted by a pipe 26 is burned in the re-heater. The fuel-gas is controlled by a valve 28, the position of which is determined by a thermostat 29 responsive to the temperature of the turbine exhaust. The supply of compressed air to the gas generator may be regulated by varying the munber of stages of the air pump with or without an additional control responsive to the load, or the supply may be regulated by blowing-off air in excess. The two turbine stages may be coupled together as shown at 10 or may operate independently.

Gear-wheel cold working apparatus for a partially formed gear-wheel 4 comprises a support 21, 22 and a disc 1 with radial teeth 2 shaped to engage the wheel teeth and impact against the teeth under spring 8 bias. The disc is forced away from the wheel as it is rotated until at a particular position the spring bias causes the wheel to accelerate and the disc and wheel to impact. The spring 8 serves to keep the wheel and disc in contact after impact. The wheel is rotated by an electric motor 16 through a pinion 20 mounted loosely on a shaft 19 to enable intermittent rotation of the gearwheel. The disc is mounted on a carriage 13 and moved therealong by a nut on the carriage threaded on a fixed screw shaft 11. The nut is rotated through gears 9, 9<SP>1</SP>, 12, driven by the disc 1. The movement of the carriage causes the disc teeth 2 to slide along the valleys of the gear teeth after impact. The carriage is returned by a hand wheel normally locked to the base 15.
