Abstract: 1362371 Pivotable windows ARCHITAL LUXFER Ltd 17 April 1972 [29 April 1971] 12300/71 Heading E1J A window assembly comprises an inner frame 2 pivotable about a substantially central horizontal axis 3 and being vertically movable upwardly into a position where a portion 19 of the outer fixed frame 1 prevents pivoting. The inner frame has a handle 10 with a cam surface 15 which engages a sloping surface on keep 12 to raise the window. When raised, the top of the inner frame engages between flange 19 and a weathering leg 22 and the bottom is locked by flange 16 on the handle. The pivot comprises a trunnion (31, Fig. 5, not shown) on the inner frame received in a bearing 33 (Fig. 4) in a member 26 which is partly supported on a spring 40 and is slidable in the outer frame. Sliding of member 26 is limited by engagement of flange 39 on the member with keeper 38, and by stop 50. In Fig. 8 (not shown) bottom flanges (46, 49) interlock when the window is raised.

Title: Supplementary frame for old windows - made in two parts, attached to frame on site
IPC: E06B1/34
Filed: 1973-05-24
Abstract: Supplementary window frame can be fixed to an existing casing already built in to the wall. By this means, one can renovate or modernise an old casing (2) built into a wall (1).

Title: Air pre-heater for I.C. engine - uses perforated deflector tube in depression in wall of air passage
IPC: F02N19/08
Filed: 1973-05-28
Abstract: The engine intake pipe has a semi-circular section depression whose axis is tangential to the main pipe. A perforated tube (4) housing an ignition plug fits concentrically in the depression and is locked in position by a nut. The engine intake air flowing through the pipe (1) is split into three separate streams. One stream passes directly across the tube through diametrically opposite perforations. A second stream passes into the tube and out through the end and a third stream passes between the tube (4) and the wall of the depression. The flame inside the tube (4) is thus protected from excessive air flow fluctuations at low engine speed. Strongly pulsed flames may be produced, the flame oscillating between positions pointing upstream and downstream.

Title: Improvements in water cooling installations - mixing preheated ambient air with satd cooling air avoids precipitation and possible frosting
IPC: F28F25/12
Filed: 1973-06-22
Abstract: A water cooling installation consists of a wet section in which stream of the water to be cooled come into direct contact with cooling air, drawn over the streams by a fan, and a tubular heat exchanger installed in a space connecting the ambient atmos. with the outlet of the flow of cooling air. This space is arranged so that the flow of cooling air, satd. with water, induces a flow of ambient air over the tubes of the heat exchanger. Hot fluid flows through the tubes of the heat exchanger, thus warming the ambient air, and the warm ambient air and the satd. cooling air are mixed before final discharge to atmos.

Title: Gas purification device - acidic metal oxide catalyst on refractory body
IPC: B01J23/745
Filed: 1973-10-25
Abstract: Device for purification of gases comprises a refractory body serving as support for a catalyst composed of acidic metal oxides, the catalysing ions of which are liberated by simple contact with molecules of oxygen or water injected into the flow of gases to be purified. The catalyst is a stoichiometric mixt. of Te2O3 and Te3O4 applied as a coating on the refractory body, the mixt. decomposing at 250-570 degrees C in a circuit of air contg. 20-23 vol. % O2 or water vapour. The device is used in factory chimney stacks to remove toxic and nauseous gases from effluent. The catalyst does not have to be regenerated, since no adsorption occurs, therefore no deposits form in the pores. The catalyst continues to operate until exhausted by erosion.

Title: Vanadium sludge from alumina ore processing liquor - impurities reduced by preliminary crystallisation step at intermediate temperature
IPC: C22B34/22
Filed: 1973-12-19
Abstract: The liquor resulting from treatment of alumina ores with caustic alkali solution is cooled to 40-65 degrees C and held until a precipitate is formed; the latter is separated and the liquor further cooled to 20-30 degrees C to precipitate vanadium sludge. PRef. the liquor is diluted after separation of the first precipitate. The initial precipitation partially removes impurities, partic. Na2SO4, K2SO4, Na2CO3 and NaF thereby increasing the concentration of vanadium in the final sludge and facilitating its recovery. Furthermore the presence of sparingly soluble vanadium salts in the sludge is minimised.

Title: Connector for standard dia. pipes or bars - has stepped dia. bore decreasing in dia. from ends
IPC: F16B7/04
Filed: 1975-01-13
Abstract: A connector for straight, elbow, or tee joints between standard diameter bars or pipes, for example carrying water or electricity cables, is in the form of a sleeve (1) with a stepped diameter bore symmetrically disposed about the centre and of decreasing diameter towards the centre. Each bore is of such a diameter that it matches one of a range of existing bar or pipe sizes and the steps (3, 5) between bores form abutments for the pipe ends. Fixing of the pipe ends is by any of the conventional methods, such as bonding, sweating or screwing. The bores will normally be circular in cross section but other sections such as hexagonal are possible. Expanding or contracting joints are easily achieved. Pipes fitting the minimum bore may butt against each other or an additional shoulder may be provided, particularly when only one of the pipes is of the minimum bore size.

Title: Vehicle drive wheel system - uses six wheels with drive wheels in middle and four steered wheels synchronised
IPC: B62D61/10
Filed: 1975-02-21
Abstract: An arrangement of six wheels on a vehicle, superior to a four wheel arrangement, has the drive wheels (3) between front wheels (4) and rear wheels (5), both the front and rear wheels being used for steering and having a synchronised action. The engine may be positioned as required, e.g. at the rear. The arrangement gives better traction as the load is normally nearer the centre of the vehicle than at the rear, and the use of four steered wheels is better than two only, especially for buses. The transmission is simplified and tendency to skid is reduced.

Title: Heating system using latent heat of immersed mass - combines solar heating panel with immersion heater for water tank
IPC: F28D20/02
Filed: 1975-08-11
Abstract: The combined water heating system has a hot water tank connected to a solar heating panel and incorporating an auxiliary source of heat immersed in the water in the tank. The water is circulated around the heating panel and the tank, and the same water is discharged from the tank for use. This auxiliary source of heat is a mass of a suitable organic salt whose fusion point is between 50 deg. and 75 deg.C. When a large amount of water is drawn off, lowering the temperature, the latent heat of the mass is transferred to the water at this temperature. An immersion heater may also be used with the tank. The system may be used without a solar heating panel, but with an immersion heater.

Title: Expansible build up drum for tyres and tyre breaker belts - has movable central segments, cylindrical springs in an elastic envelope
Inventor: MOROZOV ANATOLY VASILIEVICH
IPC: B29D30/24
Filed: 1975-09-08
Abstract: Drum comprises central segments fastened on levers which are displaced by an opening mechanism; cylindrical springs fastened at the segments, and an elastic envelope covering the springs. The springs are shaped as a bellows whose elements are distributed over the width of the bearing surface of the segments of the drum, and have lateral sections whose shape corresponds with the profile of the type to be built up. The elements of the spring embrace the expansible segments and are, in addn., bearing on elastic stringers whose one end is connected with a given segment whilst the other end slides freely over the adjacent segment as the drum is being expanded. Drum construction prevents deformation of the tyre to be built-up.
