Abstract: 1,145,145. Hair driers. EUGENE Ltd. 26 June, 1967 [30 June, 1966], No. 29420/66. Heading ASR. A hair drier comprises a motor and fan unit 20 for supplying air to the hair via a delivery duct 24 and perforations 4 in the inner wall of a double walled hood 1, the motor and fan unit being situated at the back of the hood and comprising a pair of centrifugal fans (22, 23) carried on the opposite ends of the shaft of a single motor, there being a manifold 61 extending substantially the whole way round the periphery of the hood so that it may draw in air after it has impinged on the hair and providing, with suction ducts 60, the sole path for the supply of air to the fan inlets. The hood 1 may be of a transparent thermoplastic material and may be contained with the motor and fan unit 20 within a casing 31 adjustably mounted on a pillar support (14). There may be two separate delivery ducts (24, 25, Figure 3, not shown) or two interconnected ducts (24, 25, Figure 4, not shown). The motor may be provided with a time switch, a heater (26, 27, or 52) in the delivery duct may be provided with an automatic temperature control of exemplified type, and the perforations 4 in the inner wall of the hood may be non-uniformly distributed and may be shaped as nozzles. There may be a valved extractor opening from the delivery ducts to atmosphere so that fresh air is drawn into the drier at the manifolding 61. In an embodiment (Figures 1-3, not shown) the suction ducts for returning air to the motor and fan unit are formed by spaces between the casings 31, the outer wall of the hood, and the delivery ducts.

Title: Improvements in dish washing machines
IPC: A47L15/23
Filed: 1952-11-21
Abstract: 721,730. Hinges. AKTIEBOLAGET ELEKTROLUX. Nov. 21, 1952 [Nov. 24, 1951], No. 29445/52. Class 65 (2). [Also in Group XXIII] Relates to hinges for the door of a dishwashing machine (see Group XXIII). Two hinge members 32, Fig. 7, mounted in the door 19 co-operate with two hinge members 31 mounted on the dishwasher housing 11. Each member 32 has a cylindrical bore 33, Fig. 8, containing a friction sleeve 34 secured in place by two nuts 35, passing through openings 37 in the sides of the member 31 and by a bolt 36 co-operating with the nuts. Between one nut 35 and a side of the member 31 is a spring washer 40 to ensure good frictional contact between the ends of the sleeve 34 and the inner portions of the sides of the member 31. Around the sleeve 34 and within the bore 33 is a tightly wound coil spring 39 formed of wire of rectangular crosssection. One end of the spring passes freely over the sleeve whilst the other end is anchored to the member 32 as shown in Fig. 7. As the door is opened the internal diameter of the spring is increased and its frictional contact with the sleeve is eliminated. When the door is released in any desired position its weight is supported owing to the internal diameter of the spring decreasing so that it is then held by the friction between the spring and sleeve. As the door is moved towards its closed position the spring exerts a braking action and may carry the sleeve with it, the frictional force between the ends of the sleeve and the sides of the member 31 then corresponding approximately to the weight of the door.

Title: Improved cushioning side bearing for railway vehicles
IPC: B61F5/14
Filed: 1939-11-07
Abstract: 536,419. Railway-vehicle undercarriages. SYMINGTON-GOULD CORPORATION. Nov. 7, 1939, Nos. 29550 and 29551. Convention dates, March 25 and April 24. [Class 103 (vi)] Side bearings adapted to be disposed between the truck and bolsters of railway vehicles comprise an upper cap which bears on shoes in which are disposed springs for taking vertical loads, other springs being arranged between the shoes to urge them into frictional engagement with the side walls of a housing which contains the shoes and springs. In one construction, Figs. 2, 3, a pair of vertical coil springs 16 are housed each in a cup-shaped member or shoe 10 and bear also on the base of a housing 1 secured to the truck bolster. A cap 21 adapted to be engaged by a body bolster bears on the cup members 10. A pair of horizontal springs 20 urges the vertical walls of the cups into frictional engagement with the vertical walls of the housing 1. The cups may have lead inserts 15 as lubricating means. The cap 21 has dependent parts 26 adapted to engage the cups 10 and the sides 7 of the housing to limit horizontal movements of the cap. Separation of the cap from the housing is prevented by a key 33. In a modification, Figs. 5-8 (not shown), the cups 10, and the ends of the housing 1 and of the cap 21 are cylindrical and a wear plate is secured to the cylindrical end walls of the housing for frictional contact with the cups. The ends of the dependent part 26 of the cap 21 are also cylindrical and partly embrace the cups so as to limit the horizontal movement of the cap. A single spring corresponding to the springs 20 is provided in this case. In a further construction, Fig. 10, the housing 150 is received in a base member 200 secured to the truck bolster A and is adjustable vertically therein by the interposition beneath the housing of shims 49 to determine the amount of compressive movement of the side bearing as permitted by the distance between the cap 21c and the upper edges of the housing 150. Apertures 47 in the cap through which these edges can be seen, and a mark 48 on the cap facilitate this adjustment. Bolts 170 which pass through holes in the front and rear walls of the base 200 and through side recesses in the base and housing as shown, prevent separation of these parts while permitting the vertical adjustment of the housing. Holes 160<SP>1</SP> in the housing and arched parts 3d at the bottom of the base member 200 provide openings through which foreign substances may escape from the housing.

Title: Improvements relating to the treatment of cellulose ester fabrics with saponifying agents
IPC: D06M11/38
Filed: 1950-12-07
Abstract: A fabric comprising high tenacity yarns of an ester of cellulose with a fatty acid containing 2-4 carbon atoms in the molecule is subjected to the action of a saponifying agent while the fabric is in the form of a roll wound on to a perforated tube, through the perforations of which the saponifying agent passes. The fabric may be bound to the tube along the selvedges by means of material which is unaffected by the saponifying agent.  Hot water may be passed through the roll of fabric immediately before the treatment with saponifying agent.  The saponification may be continued until the cellulose ester, e.g. cellulose acetate, is converted to regenerated cellulose.  The assembly of fabric wound on the tube may be wrapped, before saponification, with a fabric resistant to the action of the saponifying agent.  The saponifying medium may be an aqueous, alcoholic, or aqueous/alcoholic solution of sodium, potassium or ammonium hydroxide, carbonate or silicate, and salts such as sodium acetate, sulphate, or citrate may be present.  An organic saponifying agent such as methylamine, ethylene diamine or triethanolamine may be used.  The treatment may be carried out at 20-100 DEG  C.  The liquid may be forced or sucked through the perforated tube and roll of fabric in either direction.  Woven, knitted, and other kinds of fabric may be treated.
