Abstract: 1,226,376. Esters of α,# unsaturated monocarboxylic acids. B. F. GOODRICH CO. 1 April, 1968 [31 March, 1967], No. 15631/68. Heading C2C. An alkyl ester of an α,# unsaturated monocarboxylic acid is prepared by reacting an α- monoolefin containing from 2 to 5 carbon atoms with a substantially anhydrous sulphate solution containing from 20% to 80% by weight of total sulphate content and comprising free sulphuric acid and recycle material including α,# unsaturated monocarboxylic acid moieties, and subjecting this reaction mixture to distillation under a vacuum greater than 200 mm. Hg. absolute at a stillpot temperature not higher than 170‹ C. taking the alkyl ester overhead as vapour and leaving a still bottom residue which is recycled, the monocarboxylic acid being added as an α,# unsaturated monocarboxylic acid containing up to 4 carbon atoms either to the said anhydrous solution or to the reaction mixture. Examples describe the preparation of ethyl acrylate using apparatus such as that shown in Fig. 1.

Abstract: 1,226,684. Electrolytically decomposing cyanide; degreasing. NORDNERO A.G. June 18, 1969 [June 19, 1968], No.30843/69. Heading C7B. In a multi-bath process for the surface treatment of metal articles which uses an aqueous cyanide solution, e.g. for Zn, Cu or Ag plating, the cyanide-containing liquid resulting from the rinsing of the articles after treatment is returned for oxidative electrolytic decomposition (to form carbonate and ammonia) to one or more electrolytic pre-treatment baths, e.g. alkaline anodic and cathodic degreasing baths, respectively containing a steel cathode and graphite anode, and both containing NaOH, Na 2 CO 3  and Na 2 SiO 3 ; the anodic degreasing bath may further contain a gluconate. Liquid from the post-treatment rinsing baths may be circulated through one or more ionexchange units, e.g. anion and cation exchange filters, to remove any remaining CN ions or metal CN complexes. An example of a Zn-plating bath contains 35 g/1 Zn, 30 g/1 NaOH and 110 g/1 NaCN, operating at a C.D. of 3-6 amp/sq dm. After plating, the articles may be HNO 3  pickled, then chromated in a bath containing alkali metal bichromate and F and SO 4  ions.

Abstract: 1,228,162. Stern tubes. J. A. RUDMAN. 17 May, 1968 [21 Feb., 1967], No. 8131/67. Heading B7S. [Also in Division F2] A ship's propeller shaft tube d is sealed from the ingress of water when the shaft g is withdrawn inboard by a cap α applied to the outer end of the tube, e.g. by being secured by brackets or dogs k to a boss h. The cap is domed at I to accommodate a bearing b supported on arms c permitting adjustment of the bearing centre relative to the centre of the cap. The bearing may support a boring bar when aligning the lining e.

Abstract: 1,230,290. Hydrostatic transmission control. EATON YALE & TOWNE Inc. 16 April, 1969 [1 May, 1968], No. 19447/69. Heading F2D. A hydrostatic transmission control linkage for a tractor comprises a lever 114 which adjusts the transmission ratio to a desired value and a pedal 144 which independently increases or decreases the transmission ratio from the desired value. Rotation of the lever 114 acts through a linkage 216, 106, 104, 174, (184), 84 to rotate a lever 70 about a pivot 92. Rotation of the lever 70 causes corresponding rotation of a lever 54 which operates a control valve 34 supplying pressure fluid to a follow-up servomotor 30 controlling the swash plate of the hydrostatic transmission. Movement of the pedal 144 acts through an arm 154, Bowden cable 132, and linkage 166, (170), 176, 90, to rotate the lever 70 about the pivot 86 and thus cause corresponding movement of the lever 54 and transmission ratio. The pedal 144 is urged by a spring 150 to its neutral position so that when the pedal is released the transmission ratio is returned to the value set by the lever 114. The lever 114 slides in a slot (324) in a housing 232 and the forward and reverse sections of the slot are offset to prevent straight through movement of the lever 114 from forward to reverse ratios and vice versa. In the neutral position the lever 114 is biased by a spring 304 towards a transverse slot 254 but is normally prevented from entering this slot 254 by an enlarged section 246 of the lever 114 engaging stop shoulders (248, 250). An outer part 200 of the lever 114 may be moved against the bias of a spring 234 relative to an inner part 202 of the lever whereupon the enlarged section 246 is moved clear of the stop surfaces (248, 250) to permit the lever 114 to enter the slot 254. During movement of the lever 114 into the slot 254 a projection 280 on the lever engages a projection 282 on a bell-crank 268 and rotates the latter about a pivot 270. The bell-crank 268 is connected by a rod 290 to an exhaust or by-pass valve (300) in the hydrostatic transmission which valve is opened when the lever 114 moves into the slot 254 to neutralize the transmission and permit towing of the vehicle. Adjustably positioned spring- pressed plungers (380), Figs. 10 and 11 (not shown) project into the path of the lever 114 to indicate to the driver that a predetermined ratio has been obtained. Additional effort is required to move the lever 114 past the plungers (380). As shown, an independently operable engine throttle control lever 120 is connected to a throttle control shaft 226 passing centrally through the housing 232.

Abstract: 1,231,564. Tobacco-smoke filters. P. E. BRUDY, O. H. BRUDY and J. E. J. HABOWSKY. 7 Feb., 1969 [9 Feb., 1968], No. 6623/69. Heading A2C. A filter for cigarettes or cigarette holders comprises an impervious, transverse wall with circularly spaced openings that converge in the direction of smoke flow and are directed towards an axially extending surface, which may be slightly roughened or treated with adhesive, whereon tarry and like matter is deposited. As shown, the transverse wall 15, which may be of aluminium foil of the order of 0.015 inch thick, has openings 16 adjacent the inner surface 17 of a cylinder 14 and directed towards that surface. The openings may be formed by piercing or punching and may be of greater length than the thickness of the transverse wall. The parts 14, 15 may be formed as a single plastics element, e.g. of polyethylene, and the transverse wall may be domed in the direction towards the mouth of the smoker. The direction of the openings may have both circumferential and radial components, and a further modification is described in which the openings are directed towards the surface of a cylindrical or frustoconical plug at the centre of the transverse wall.
