Title: Improvements in means for converting reciprocatory rectilinear motion into rotary motion
IPC: F16H25/12
Filed: 1934-07-23
Abstract: 431,237. Cam mechanism; internalcombustion engines. BORS, K., Kosice, Czecho-Slovakia. July 23, 1934, No. 21527. Convention date, July 27, 1933. [Class 80 (iii)] [See also Group XXVII] In mechanism of the kind in which a reciprocating part such as a piston 1 rotates a shaft 7 by means of a cam 6 and at least two rollers 5 or the like symmetrically placed, the cam having at least two acting surfaces, the axis of rotation of the cam coincides with the axis of the piston. The cam shown is sinusoidal and has at least two " waves." The piston is prevented from rotating by projections 13 and guideways 12, or by separate slides mounted on the roller shaft 3. In an application to a two-stroke internal-combustion engine, Fig. 2, the cylinder 11 is formed with slots 12 by which the piston is guided by means of its projections 13. Through the projections a bolt 14 passes carrying conical rollers 15 in engagement with a cam slot between cylinders 16, 17 which are secured together and to a driving shaft 22.

Title: Improvements in or relating to the manufacture of double-walled glass flasks
IPC: C03B23/13
Filed: 1926-09-01
Abstract: 267,005. Siegheim, F. Sept. 1, 1926. Forming hollow-walled vessels.-Relates to the method of manufacturing vacuum flasks in which a.n inner vessel is inserted in an outer vessel having one end closed, and the vessels are melted together along their upper rims. According to the invention, the inner vessel is first formed with a neck which is shorter than that of the finished flask, and after being joined to the outer vessel, it is shaped to its final form in a mould. The outer and inner vessels a, d, Fig. 1, are blown in moulds so that the bottoms are of the final shape, and the inner vessel is formed with a short neck h having a flange c. After the vessels are assembled, as shown, with asbestos spacers e, the upper rims of the two vessels are reheated and joined together, and the neck so formed is worked until it is roughly shaped, as shown in Fig. 3. The flask is then placed in a mould consisting of a base f, Fig. 4, having a projecting mandrel g which is enclosed by mould sections h. The neck is then shaped by rotating the flask relatively to the mould and blowing into the space between the inner and outer vessels. The joint between the inner and outer vessels lies on the outside of the neck below the rim and is protected by the metal casing of the flask.

Filed: 1947-08-07
Abstract: 5 : 5-Diarylhydantoins (in which the two aryl groups may be linked together directly as well as through the 5-carbon atom of the hydantoin ring) are manufactured by treating diaryl ketones (including fluorenones) with a water-soluble cyanide (especially an alkali metal cyanide) and a reagent derived from the system NH3-CO2-H2O and capable of regenerating these components under the conditions of reaction, in the presence of an organic solvent at least partially miscible with water (e.g. an alcohol, amine, ester, ether or amide of relatively low molecular weight), and then acidifying the reaction mixture.  The reaction is advantageously carried out at 50-150 DEG  C., preferably while preventing the escape of volatile components.  The following reactants and solvents are specified and some of then employed in examples: benzophenone and its p-bromo-, p-chloro-, p-amino- and p : p1-bis-(dimethylamino)-derivatives, fluorenone, di-p-tolyl ketone and p-anisyl phenyl ketone; sodium, potassium, lithium and calcium cyanides; ammonia and carbon dioxide as such, ammonium carbonate and ammonium carbamate; acetamide, propionamide, butyramide, methyl, ethyl and n-propyl alcohols, ethyl acetate, dioxane, morpholine, pyridine, mono- and di-ethanolamine, propanolamines, ethylene glycol and its mono-methyl and -ethyl ethers, 1 : 2-propylene glycol and glycerol.

Title: Rotary inertia device and fluid braking system
Inventor: MORTIMER FRANK RADCLIFFE
IPC: B64C25/46
Filed: 1955-07-28
Abstract: 812,553. Brake control mechanism. DUNLOP RUBBER CO. Ltd. July 11, 1956 [July 28, 1955], No. 21765/55. Class 103 (1). In order to ensure a correct amount of frictional interference between the peripheral tyre of the rotatable housing of a rotary inertia device for anti-skid control and a wheel or like rotatable member, spring means are provided to urge the housing of the rotary inertia device against the wheel or like with a force which is substantially constant to automatically compensate for wear of the housing tyre. In the embodiment illustrated applied to an aircraft wheel, the casing 10 of the rotary inertia device (e.g. of the type disclosed in Specification 676,708) is pivotally secured to the non-rotatable torque plate 2 of an aircraft disc brake. The rotatable housing 6 of the rotary inertia device 1 has a peripheral solid rubber tyre 7 and is adapted to engage, and be rotated by, the rim 8 of the aircraft wheel 9. A pivotal connection is provided at ends 14 and 15 of the casing 10; the latter end being spring-loaded by arrangement 34 so that the tyre of the rotatable housing 6 is constantly resiliently urged to bring the tyre 7 into frictional contact with the rim 8 of the aircraft wheel. If desired, both ends 14 and 15 of the casing 10 may be provided with spring-loaded pivotal connections with the non-rotatable torque plate 2. The device is preferably so located on the torque plate 2 that the spring-urged end 15 of the base 11 is radially closer to the centre of the wheel than the pivoted end 14; thus eliminating any tendency of the tyre 7 to jam on the rim 8.

The upright member 7 is secured to the base 8 of the frame and to a further support 12 at right angles thereto. The member 7 is formed with an opening 52 in which is disposed the bearing means 49 which is carried by a pair of leaf springs 50 clamped by brackets 51 one each side of the supporting member. The bearing means rotatably supports the spindle which is axially fixed with respect to the bearing means, and an eccentric 54 is connected by a rod 55 to the bearing means to axially reciprocate the bearing means in the opening 52. The brush is mounted on the spindle at one side of the supporting member, and pulleys are mounted on the spindle at the other side of the member for receiving a belt 63 driven by a motor 58 on the further support 12. The work is carried beneath the brush 10 by a belt conveyer 9 having a freely rotatable roller 20 and a roller 19 mounted on a shaft 19<SP>1</SP> driven by reduction gearing 46 and belt drive 60 from the motor 58, the belt also driving a pulley 57 of the eccentric 54. The conveyer and rollers are mounted on a frame 22 vertically adjustable on the supporting member 7 by a hand wheel 26 and screw 24 engaging a nut 27 on the frame 22 to compensate for different thicknesses of workpieces and wear of the brush. The work is held down on the conveyer by rollers 30 carried by arms 32 on a second frame 35 which is vertically adjustable relative to frame 22 by a screw 38 and hand wheel 41 to accommodate workpieces of different thicknesses. Leaf springs 36 act on the arms 32 to press the rollers towards the conveyer. The arms are pivoted to brackets 42 horizontally adjustable towards and from the brush on the frame 35. The machine may be enclosed by housings (5, 6, Fig. 1, not shown). If the machine operates dry, the housing (5) may be connected to a dust extractor. If coolant is supplied to nozzles 80, a tray 72 collects the waste and is connected to a drain 78.

The fuel rods may comprise pellets of uranium dioxide in beryllium tubes closed by beryllium studs with the interposition of alumina pellets. H-shaped beryllium plates 5 are attached at each end of two of the sleeve walls and carry studs 31 which are joined to the studs on an adjacent fuel element by loosely-fitting links 30. A projection 45 at the upper end of the element fits into a recess 46 in the adjoining element. A string of elements is located in a vertical coolant channel in a reactor core and coolant passes both inside and outside the sleeves 2. The elements may also be used in horizontal fuel channels. Instead of uranium dioxide, the fuel may be uranium dioxide mixed with plutonium dioxide or thorium dioxide, or a mixture of plutonium dioxide and thorium dioxide. The Provisional Specification refers also to coupling means consisting of lugs on a lower element engaging with shoulders on an upper element.
