Abstract: 137,359. Jack, J. Jan. 2, 1919. Spring wheels with continuous outer rigid ring and volute springs and metal springs other than helical and volute springs.-In spring wheels, an octagonal plate A<3> rigid with the boss A' of the hub carries a series of projecting arms B, each pair making a wedge-shaped cup B<1>. Each cup carries a volute or like spring E bearing on a leaf spring F, the inturned ends of which engage the outer walls of the cup B<1>. The arrangement may be duplicated, or, in another form, two leaf springs may co-operate with each volute spring. A face-plate J is fixed on each side of the wheel by bolts K with spring washers allowing relative movement.

Title: Hydroxysteroid ketals
IPC: C07J21/00
Filed: 1953-01-01
Abstract: The invention comprises 11b  - hydroxypregnane-3 : 20-dione 3 : 20-alkanediol diketals of the general formula <FORM:0743487/IV(a)/1> (wherein R represents a hydrogen atom or an alkyl radical containing from one to six carbon atoms, and n is one or two, subject to the restriction that when n is two, R contains not more than five carbon atoms), together with a process for their preparation by reduction of the corresponding 11-keto derivatives in an organic solvent at a temperature between 0 DEG  C. and the reflux temperature of the reaction mixture.  Specified reducing agents are lithium aluminium hydride, sodium borohydride, lithium borohydride, and hydrogen in the presence of catalysts, e.g. Raney nickel or platinum.  In an example: pregnane-3 : 11 : 20-trione-3 : 20-ethylene glycol diketal in benzene is refluxed with ethereal lithium aluminium hydride and the product treated with ice to yield 11b -hydroxypregnane - 3 : 20 - dione - 3 : 20 - ethyllene glycol diketal, which may then be hydrolysed to 11b -hydroxypregnane-3 : 20-dione.  The same diketal is also prepared using as reducing agents lithium borohydride in aqueous ethanol, and sodium borohydride in aqueous isopropanol.  Other 11b -hydroxy-3 : 20-diketals mentioned are those derived from propane-, butane-, pentane-, hexane-, heptane-, octane- and 4-methylpentane-1 : 3-diols and from propane-, octane- and 3-methylbutane-1 : 2-diols.

Patent GB-750702-A (GB)
Title: A method of making cellulose acetate fibre
IPC: D06M13/188
Filed: 1954-01-04
Abstract: Fibres of cellulose acetate having a combined acetic acid content of 40-62 per cent by weight are obtained by impregnating cellulosic fibres with an acetylation catalyst from an aqueous solution of the catalyst, treating the impregnated fibres with acetic acid vapour at a temperature of 100-130 DEG  C. in order substantially to replace the water in the fibres, and subsequently treating the fibres with acetic anhydride vapour at a temperature of 100-140 DEG  C.  Before being treated with the acetic acid vapour, the impregnated fibres may be partially dried in order to reduce the amount of water to be removed by the acetic acid.  The cellulosic fibres may be in the form of loose fibres or in the form of yarns or fabrics.  Viscose staple rayon having a permanent crimp may be subjected to the treatment, and the resulting cellulose acetate fibres retain the crimp.  The process is preferably carried out with the cellulosic fibres advancing continuously through each successive step.  The acetylation catalyst may be a salt, e.g. sodium, potassium, or lithium acetate; di- or tri-sodium or ammonium phosphate; zinc, copper, aluminium, stannous, or stannic, chloride; copper, zinc, or aluminium sulphate or alum; or ammonium oxalate.  The treatment with acetic anhydride vapour is continued for at least 3 hours, prererably 4-7 hours.  The supply of acetic anhydride vapour to the treatment chamber is preferably renewed continuously.  Dyed cellulosic fibres such as viscose staple fibres may be subjected to the acetylation without change in the colour or shade.

Title: Improvements in machines for offset printing
IPC: B41F17/00
Filed: 1954-01-06
Abstract: 763,572. Printing machines. HARRISON, W. Jan. 5, 1955 [Jan. 6, 1954; Aug. 11, 1954], Nos. 317/54 and 23298/54. Class 100(2) A machine for printing on articles having iregular surfaces comprises two or more elastic pads mounted on a rotatable frame and movable alternatively into contact with inked design-carrying, surfaces, e.g. plates and with articles to be printed. As shown, in Fig. 1, the frame 9 is rotatably mounted on a vertically reciprocable shaft 5 projecting upwardly through the surface of a table 1, and is located in four positions at right angles by a rib 7 on a collar 6 on the shaft engaging in notches 8 in a collar fixed to the frame. The lower end of the shaft is connected to a pneumatically operated piston in cylinder 11. The shaft may alternatively be reciprocated by other mechanical, electrical or manual means. Equally spaced around a circle concentric with the shaft 5 are design plates 3 and carriers 4 for the articles to be printed. The design plates are etched or intaglio plates e.g. metal or glass or the design surface may be carried on cylinders of a rigid material on sheets or bands of a flexible material as described in Specification 784,412. The machine may be used for single or multicolour printing. For single colour the pads are brought down on to the design plates, the frame is turned through 90 degrees .and the pads brought down on to the articles to be printed. The frame is then turned back to the initial position and fresh aricles positioned on the carriers 4 before the operation is repeated.. For multicolour printing the design plates 3 are inked in different colours and after the first printing operation as before, the pads are brought back to the initial position'reinked from the design plates and rotated 90 degrees in the opposite direction to print the articles in the second colour. Instead of having two design plates and two article carriers, arrangements are described using only one or three. The pads may be solid or hollow and filled with gases, fluids or flexible jellies. Alternatively a slab, sheet or film of elastic material may be used, being alternately forced by the pad against the inked design plate and the article to be printed. Instead of being mounted to move in a horizontal plane the pads may move in a verticle plane. In this case the pads are mounted on radial sliders for movement into and out of contact with the design plates and the articles to be printed. Opposite pads may be mounted on a diametrical rod so that when an article is brought into contact with a pad at one end, the pad at the other end,is forced into engagement with the design plate. Specifications 23009/03 [Class 100] and 763,571 also are referred to.

Title: Improvements in and relating to electric time relays
IPC: H01H47/18
Filed: 1938-01-06
Abstract: 498,717. Electromagnetic relays. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 6, 1938, No. 440. Convention date, Jan. 7, 1937. [Class 38 (v)] In a time delay relay with two windings, the operating or release time of the relay is determined by the decay of the charging surge of current that occurs when a condenser is placed in circuit. Fig. 1 shows a form in which operation of the relay is delayed. Closure of a switch S energizes the working winding 1, 2 and also causes a surge of current to charge a condenser C through an opposition winding 4, 5. Only when the surge diminishes sufficiently, due to the condenser becoming charged, is the winding 1, 2 powerful enough to operate the relay. The contact r then moves across and the condenser is discharged through a resistance W. In an alternative arrangement, the charging surge at first overpowers the current in 1, 2 and operates the relay at once, the relay subsequently being released and again operated as above. In Fig. 2, movement of a switch S to the left causes the winding 1, 2 to operate a relay. Subsequent movement of the switch S back to its original position causes a surge of current through the winding 4, 5 to charge the condenser C. This current assists the dying away current in the winding 1, 2 and prevents the relay from releasing till after a time interval. Specification 484,458 is referred to.
