Title: Improvements in speed controlling arrangements
IPC: F16D33/14
Filed: 1950-02-20
Abstract: 690,873. Speed governors. SINCLAIR, H. Feb. 6, 1951 [Feb. 20, 1950], No. 4351/50. Class 57 [Also in Group XXIX] An arrangement for controlling the speed of a machine driven through a hydraulic turbo-coupling of the variable fill type comprises a positivedisplacement setting pump 15 driven at a constant speed by a motor 20 and having a delivery adjusting member 38, and a positive-displacement metering pump 16 driven by the machine whose speed is to be controlled, the delivery passage of the setting pump 15 being connected to the inlet passage of the metering pump 16 through a control duct 33 incorporating an operating chamber 18 containing an actuator 29 which controls the filling of the hydraulic coupling. The latter may be of the kind described in Specification 493,703, [Group XXIX], whose scoop control is operated by the actuator. The metering pump 16, which also has a delivery adjusting member 39, delivers through a pipe 35 to a reservoir 17 containing a filter 36. The chamber 18 contains a metallic bellows 26 connected to the spring-loaded actuator 29 and variations in the relative speed of the pumps cause variations of pressure in the chamber which pressure .acts on the bellows thereby moving the actuator. A relief valve 37 is provided. In another embodiment a single multiple-delivery setting pump delivers liquid through separate control ducts, each including an actuator, to a pair of metering pumps each driven by a hydraulic coupling. One or more setting pumps may be combined with a plurality of metering pumps.

Title: Improvements in or relating to air screws
IPC: B64C11/20
Filed: 1938-02-15
Abstract: 552,088. Airscrews. ADLINGTON, G. S., and RAYOID MANUFACTURING CO., Ltd. Feb. 15, 1938, No. 4744. [Class 114] The blades of an airscrew are provided with a protective sheath consisting of sheets of nitro cellulose or cellulose acetate which have been previously treated with a solvent, and also with a non-solvent which controls the degree of plasticity and shrinkability. Such plasticizing treatment may be effected by a mixture of a non-solvent and a halogenated hydrocarbon converted into a solvent as by the addition of alcohol. The non-solvent is subjected to toluene or petrol, whilst the plasticizing element is subjected to glycol-phthalate. The surface of the blade is provided with an adhesive priming coat, and the sheath similarly provided with a gum materialh dissolved in acetone. The sheet is applied to the surface and held under pressure, and preferably the sheets are initially larger than the blade axis, the extending edges being bevelled and folded over to provide a fair joint. In the event of damage to a part of the sheathing, a repair may be effected by filling up with a paste consisting of clear nitro cellulose dissolved in acetone. Preferably before plasticizing, samples of the sheets are tested, and in the case of nitro cellulose material, any having a flash point lower than 180‹C. is rejected. In the case of cellulose acetate material, rejection is made if it carbonises at a temperature of less than 220‹ C. Specification 552,087 ,[Group IV], is referred to.

Fig. 1 shows the pivoted bar form and Fig. 4 a section thereof. The pivot l is riveted over at one end behind the mounting disc c and at the other end into a countersunk boss j in the bar b. The disc c is secured by screws from a rear plate entering lugs on the disc. A flange k on the bar b lies flush with the door to prevent a tool being inserted. The notched boss, Fig. 2, is likewise secured by screws from a rear plate entering lugs on the boss mounting. The lock a comprises, Fig. 5, a spring-urged bolt p which can be deadlocked by the slide v moving its transverse lug x out of line with a slot y in the bolt ; the slide v is actuated by the extension from a cylinder lock, housed in a recess on the casing a, which on further movement lifts the bolt p to release the lock a from the notched boss. The hinge connection for the lock casing a and the bar b may comprise a hinge pin with a head larger than the countersink of the eye and a similarly headed screw to screw in a bore in the pin : after assembly the two heads are filed to lie flush with the hinge eyes.

[Also in Division C6] The grain surface of leather or leatherlike materials (e.g. that known under the Registered Trade Mark "CORFAM"), e.g. in the toe portions of shoe uppers, is sprayed with hot moist air or steam immediately before and/or as the material is stretched. The word "immediately" means stretching within 5 seconds of the finish of the gas treatment or before the grain surface has fallen to below 45‹C. A suitable steam spraying device which may be incorporated into a conventional lasting machine, may comprise a metal block 12, having a recess 14, which has an inlet 18 tangential thereto, for steam from a source not shown via pipe 24, and a nozzle 26 mounted in recess 14 and having an outlet 28 for the steam. In recess 14 the large water droplets are removed from the steam. A valve may be present to control the flow of steam through outlet 28. In one embodiment the valve 36 comprises member 38 normally held by spring 50 in a closed position. When compressed air is passed via pipe 42 into chamber 40 the member 38 is retracted such that steam issues from outlet 28. In another embodiment the valve may be operated by means of a solenoid. Thermostatically controlled heaters 58 may be present to prevent condensation. An annular chamber 68 (Fig. 3, not shown) may extend from end 16 and surround nozzle 26 such that hot air may be blown on to the leather. The hot air is supplied to the annular chamber by a tube tangential thereto.

Title: Automatic multi-spindle lathe
IPC: B23B9/10

Abstract: 827,672. Automatic lathes; machine-tool details. PETZOLDT, F. G. J. E. Feb. 14, 1957 [Feb. 21, 1956], No. 5141/57. Class 83 (3). A multi-spindle automatic lathe comprises a central shaft supported along an intermediate portion in the lathe-frame, an indexible workspindle-carrier being mounted and supported on one of the free ends of the central shafts. The indexible work-spindle carrier 34, Fig. 2, is shown carrying four spindles driven from a central shaft 14 and gearing 47, 48, Fig. 3. Indexing is effected by a rotating arm 51 carrying a roller 52 adapted to engage slots 53 in the end of the spindle carrier. The latter is locked in the indexed positions by a radially-arranged spring-pressed latch 54, which is lifted by a bell-crank 58 operated by a cam 49 on the shaft 50. The spindle - carrier comprises end flanges 36, 37, Fig. 2, joined by a boss 35, and is rotatably supported on the end of a hollow shaft 17. The latter is supported in a snoutlike member 15 forming part of the upper frame of the machine. The opposite end of the hollow shaft to that supporting the work-spindle carrier is used to carry a toolspindle support 23. The frame is arranged to form reservoirs 60, 61 for oil, one at the work-spindle end and the other at the tool-carrier end respectively. An oil-pump 63 draws the fluid from the interconnected reservoirs and passes it to a pipe, from which it is sprayed on to the two carriers for lubricating purposes, and also to maintain an even temperature between the parts of the machine. Two pumps may be used to transfer the oil from each reservoir to the opposite carrier. An alternative arrangement of the hollow support shaft provides for its rotation in the frame, with the work-spindle carrier fixed to it at one end. Means are described for taking-up end-thrust on the work-spindle carrier during machining, one method including spring washers 68, Fig. 2, and a conical-seating 39 in the frame for the end flange 37 of the carrier. An alternative method consists in a flange 95, Fig. 8, provided on the carrier and oppositely-disposed pairs of thrust-rollers 101, 102, mounted on adjustable eccentric-pins in the frame 91.
