In a building having an air extraction duct associated with a W.C. and/or bathroom, an air heating and ventilating system comprises a fresh air inlet duct leading to a heater incorporating a fan, outlet ducts from the heater to air outlets within the building, and an outlet leading to the extraction duct, which outlet is in communication with parts of the building other than the W.C. and/or bathroom so that air may be extracted from said parts of the building. The outlet may be disposed within the W.C. and/or bathroom itself and communicating with the said other parts through ducts or directly through the W.C. and/or bathroom. Alternatively, the outlet is disposed centrally within the building and is linked by a closed duct to the extraction duct. Recirculation air inlets may be provided, communicating with the heater through a fresh air/recirculation air proportioning damper. One or more variable output air extraction fans are arranged in the W.C. and/or bathroom so that the volumes of air extracted and fresh air admitted are equal. A hall of the building may be arranged as a plenum chamber for the extraction fans.

Abstract: 1,226,934. Filter press. K. I. KURITA. 20 Jan., 1969 [5 NOV., 1968], No. 3115/69. Heading BID. As successive plates of a filter press 1 are moved to the right (in Fig. 1) after pressing, their cloths 10, which are each secured to the bottoms of two adjacent plates and looped over a rod 9, suspended by springs 8 from pivot joints (7) between arms 5, 6, are opened out as shown and simultaneously vibrated by means 17, which is progressively moved to the left by screw 15, geared to the platespreading mechanism, to vibrate each cloth in turn. In Fig. 1 the vibrating means comprises a pair of rotary shafts 16 carrying cams 17, which slide along the shafts between collars 21 and are keyed to turn with the shafts, cams 17 engaging and depressing rods 9 against the restoring force of springs 8 (Fig. 4, not shown). In Figs. 5, 6 (not shown) a single rotary shaft (33) carries a cam (40) which causes a vertical rod (35) to oscillate vertically, and the rod carries a member (34) which repeatedly strikes the rods 9. In Fig. 7, screw 45 moves a plate 50 along the press, which plate carries a cross-plate 55, mounted on springs 59 and vibrated by an eccentric weight 58 rotated on bearings 56, mounted on cross-plate 55, by a belt drive from motor 51 on plate 50. Extensions 62 - 66 from the ends of the cross-plate transmit the vibrations to rods 9. In Figs. 10 - 13 (not shown), the cloths are vibrated by a vertically oscillating striker (105) driven by a pneumatic ram (90), which is mounted on rollers and pulled along the press by a chain drive. The ram is supplied with compressed air through a flex-, ible pipe, and an electromagnetic valve, geared to the chain drive, switches air to each end. of the ram alternately.

Abstract: 1,238,060. Collapsible steering columns. CHRYSLER CORP. 20 Dec., 1968, No. 60741/68. Heading B7H. [Also in Division E2] Resilient plastics shoe members 78 for connecting a bracket 46 on the housing of a collapsible steering column to the structure of the vehicle each comprise slotted body portions 80, 82 for receiving portions of the bracket 46 on either side of an open-ended slot 74 formed therein, generally circular spring portions 122, 124 connecting the body portions with provision for relative flexing to accommodate misalignment of the sides of the slot 74, and a central aperture 100 for receiving a bolt 55 which secures the shoe member 78 and bracket 46 to a structural member 44 and carries a nut 56 and resilient frusto-conical 102 through which a clamping force is applied, to the body portions 80, 82 to create a frictional engaging force between the shoe member 78 and the bracket 46. Detents 108, 114 around the central opening 106 in the washer 102 and on the nut 56 cooperate to prevent unintentional loosening of the nut. Pointed fingers on the washer 102 bite into the shoe member 78 to spread apart the body portions 80, 82 and ensure engagement of the inner surfaces 92, 94 of the slots in the body portions and the edges of the slot 74. The shoe member 78 may be made of acetal resin. The bracket 46 is secured to the housing 16 by bolts 68, to a bracket 40 depending from a dash member 14 by two shoe members 78, and to another structural member (not shown) by a further shoe member 78. The housing 16 includes a collapsible convoluted portion 38 and a flange portion 32 which is bolted to a flange 30 attached to a floor panel 12 by bolts 36. A telescopic steering shaft 18 mounted in the housing 16 carries a steering wheel 20 at one end and is connected at the other to a steering gear assembly 22 through a coupling 24. If an axial impact load on the steering wheel 20 exceeds the combined frictional restraint of the shoe members 78 the bracket 46 slips relative to the shoe members to allow the upper part of the housing 16 to move downwardly and collapse the convoluted portion 38.

Abstract: 1,251,868. TiO 2  concentrates. FABRIQUES DE PRODUITS CHIMIQUES DE THANN ET DE MULHOUSE. 21 March, 1969 [26 March, 1968], No. 15126/69. Heading C1N. TiO 2  concentrates are obtained from ironcontaining titanium ores e.g. ilmenites by boiling the ores with hydrochloric acid of a concentration which initially is not substantially above azeotropic in an amount at least twice that theoretically necessary to convert all the iron in the ore to iron chloride, and maintaining a substantially azeotropic concentration of free hydrochloric acid in the reaction mixture for at least the major part of the duration of the reaction by continuously distilling off any excess water present and water formed in the process. In one embodiment, the reaction mixture is first boiled under total reflux for 1¢ hours, and after fractional distillation of water for 10 hours, water is added to precipitate dissolved T 1 O 2  and boiling then continued under total reflux for ¢ hour. The amount of water added may be approximately equal to the amount eliminated by distillation. This water may be recycled. After cooling, and separating solid and liquid phases, the solid TiO 2  concentrate (above 90% TiO 2 ) is washed with azeotropic HCl and then with water, dried and optionally calcined. The liquid phase is treated to recover HCl, which is re-used in the process. Apparatus comprises a plurality of reaction vessels each provided with an agitator, bottom discharge means, a fractionating column and associated condenser, a reservoir for receiving and storing liquid from the condenser, and a valved conduit from the reservoir to the upper part of the reaction vessel. The reflux ratio in each fractionating column is adjustable (e.g. by dephlegmators) from 100% downwards, and the columns are capable of separating material of b.p. 100‹ C. from material of 110‹ C.

Abstract: 1,256,670. Valves. LUCIFER S.A. 14 April, 1970 [15 April, 1969; 8 Jan., 1970], No. 17577/70. Heading F2V. An O-ring 13 couples the closure member 33 of an electromagnetically operated valve to a movable part 9, the ring having an outer diameter larger than a diameter 31 of the part 9 and an inner diameter smaller than the diameter of a part 32. The part 9 thus acquires kinetic energy before engaging the 0-ring which provides cushioned engagement with the closure member. In the embodiment illustrated, the closure member includes a diaphragm 34 which is normally actuated by fluid pressure when a pilot valve 39 is lifted against a spring 40 by energization of an electromagnet 18. When the fluid pressure is insufficient to operate the diaphragm the closure member is lifted by the part 9 and the 0-ring in the manner described. In a simplified embodiment, the pilot valve is omitted.
