Abstract: 1,076,135. Washing vehicles. A. KULLEN. Nov. 2, 1964 [Nov. 8, 1963], No. 44559/64. Heading B7J. A vehicle washing apparatus comprises a vertical supporting frame or rack 4, Fig. 1, provided with washing means and movable on a U-shaped guide rail 3, Fig. 3, along three sides of a vehicle disposed within the guide rail 3. The rack 4 includes spaced vertical rods 7, Fig. 6, supporting by bars 8, a central tubular post 9. The latter has upper and lower brackets 12 swivellably mounting a U-shaped frame 15 for a vertical rotary brush 5. The lower ends of the rods 7 mount rollers 11 engaging the rail 3, whilst short arms 28 on the upper ends mount removable rollers 24 engaging both sides of a depending web of a T-section U-shaped rail 21 mounted above the vehicle and parallel to the rail 3. The rail 21 is carried by a frame structure 40, 43, 44. The brush is rotatable by a motor 17 and at least one roller 11 is driven by a motor 10. A weight slidable in the tubular post 9 is connected by a cable to the end of an arm 19 secured to the frame 15, whereby the swivellable frame is resiliently urged against the sides of the vehicle. The motor 17 drives the brush 5, e.g. by a chain, gear, belt or the like, enclosed in a house 18. Mounted above the U-shaped rails 3, 21 in a central frame 42, are reels 35, 38 for paying out a water supply hose 36 and an electric supply cable 39, respectively, against the actions of springs. The hose and cable connect in known manner to a rotary fitting at the end of a Y-shaped pipe assembly 48, 49, 49 carried by the top of the rack 4. The ends of the pipes 49, 49 are provided with connections to spray nozzles Fore and aft of the brush 5. In a modification the upper rollers 24 are removed and the rack 4 is braced by a jib 25 (shown diagrammatically in Fig. 3) securable to the rods 7 and carrying a single ground engaging wheel, all as described with reference to Figs. 4, 5 and 7 (not shown). The rack is and washing nozzles are controlled automatically by limit switches and the end of the vehicle adjacent the open ends of the rail 3 may be cleaned manually whilst the other sides are cleaned automatically. Alternatively the swivelling frame and brush 5 may extend to the centre of the vehicle 2 as viewed in Fig. 1.

Abstract: 1,180,709. Purifying aromatic hydrocarbons. ESSO STANDARD FRANCAISE S.A. 19 Sept., 1968 [27 Sept., 1967], No. 44638/68. Heading C5E. Impure aromatic hydrocarbons are purified by the steps of (1) complete hydrogenation of sulphur compounds and ethylenically unsaturated hydrocarbons contained therein, without hydrogenation of the benzene rings, (2) cooling to obtain crystals, and (3) washing the crystals with a compound that is liquid at the crystallization temperature, is miscible with the mixture of hydrocarbons being treated, and which has at the pressure of operation a boiling point between 10‹ and 90‹ C. less than the melting point of the aromatic being purified. Propane is a suitable washing liquid. The hydrogenation may be carried out in two stages, with a fractionation stage optionally interposed, a suitable hydrogenation catalyst being sulphurized nickeltungsten. The products may be treated with sulphonic acid to remove last traces of sulphur. Examples describe recovery of benzene from steam-cracked naphtha.

Abstract: 948,538. Lids for kettles. BULPITT & SONS Ltd. Dec. 17, 1962 [Dec. 15, 1961], No. 44957/61. Heading A4A. To avoid heating of the handle 8 of a kettle, an obstruction inside the kettle fouls a lateral projection 13 pressed out of the skirt 6, which locates the lid in the filling opening, to prevent location of the lid in the opening in the position in which steam from a vent 5 impinges on the handle. The obstruction is formed by a part of the periphery of a cup 10 secured to the screwthreaded attachment part 11 at the end of the handle by the handleanchoring nut 12 and the lateral projection 13 is of greater length than the vent 5 to ensure that the vent is clear of the handle. The projection also prevents tilting of the lid when the kettle is in pouring position. In a modification one limb of an L-section flange is secured to the anchorage for the handle the other limb depending and being bent to the periphery of the filling opening to lie in the path of a projection on the skirt 6, the length of the depending flange being such that the vent is clear of the handle.

Abstract: 1280047 FET frequency changer circuits MATSUSHITA ELECTRONICS CORP 16 Sept 1969 [19 Sept 1968] 45493/69 Heading H3T [Also in Division H1] A frequency changer has two IGFETs connected with their sources and drains in parallel and a third IGFET connected in series to the shared drain connection of the other two. The output from a local oscillator is fed to the gate of one of the pair and the input signal is fed to that of the other. Alternatively the one of the pair may itself constitute the local oscillator. As shown a particular embodiment uses triode IGFETs but one or more tetrodes may be used. The particular embodiment is integrated in a single semiconductor wafer which has in one surface a central region 15 of opposite conductivity type to the bulk and constituting the drain of the third IGFET, a spaced surrounding region 12 constituting both the source of T 3  and the shared drains of T 1  and T 2 . A further region 10 surrounds these and constitutes the shared source of T 1  and T 2 . The gate electrode 14 of T 3  is a closed figure and the U-shaped gate electrodes 11, (13) of T 1  and T 2  together have a similar shape to electrode 14. In N-channel depletion mode devices especially, highly doped anti-inversion regions 16, 17 are formed in the substrate to complete the closed figure otherwise formed by the gates 11, 13 of T 1  and T 2 .

[Also in Divisions G1 and G4] Liquid samples contained in transparent vessels are examined for the presence of foreign solid matter by rotating the vessels at high velocity in one direction suddenly switching the rotation to a low velocity rotation in the reverse direction so that any foreign matter present swirls up along the central axis of the vessel, directing a beam of light along this axis and photo-electrically detecting scattered light from the foreign matter as the low velocity rotation proceeds (see Divisions G1 and G4). Transport system.-Sample vessels are fed consecutively through a shoot 5 and cleaning belt 3 on to a slowly rotating turret 7 carrying a plurality of turntables 8 for respective sample vessels. The turret is intermittently rotatable, a screw conveyer 6, Fig. 2, being used to feed the vessels on to the turret, where they are gripped by claws 9 and spring-urged top clamps 11. In another arrangement, Fig. 3, a star wheel 6<SP>1</SP> is used to feed the vessels and claws 9 are omitted.
