Abstract: 1,262,633. Claw clutches; change-speed gear; belt gearing. PERKIN-ELMER Ltd. 7 Feb., 1969 [8 Feb., 1968], No. 6252/68. Headings F2C, F2D and F2Q. In a direct-reduced 2-speed drive of an optical attenuator 1 of a spectrophotometer, the direct clutch-parts 2, 7 are turned relatively into or near the single correct phased position before clutch engagement by biasing means such as a V-shaped wire spring 19 on one member 7 engaging a roller follower 20 on the other member 2. The clutch is a taper pin 10 on an arm 17A rotating with the output shaft 2 and axially movable thereon into clutch engagement with a hole 13 in the input member 7, which ensures final accurately phased registration. Alternatively the biasing spring 19 and follower 20 may be replaced by providing the clutch hole 13 with V-shaped entry sides producing the bias and axial thrust provided by a spring, or a permanent or electromagnet. The input member 7 is driven through a limited arc by an electric motor 3 driving a rubber-tracked quadrant 5 secured to the input member 7 and carrying a recording-pen cable 6. Change-speed gear.-The reduced ratio is through a countershaft 8 connected by driving belts 22, 23, or fine-linked chains (jeweller's type) with the input member 7 and a loose pulley 9 clutchable to the output shaft 2 for reduced drive by a claw-clutch 14 engaged by energizing an electromagnet 15, which thrusts the pulley rightwards through a lever 16 and bowed spring 18. De-energizing the magnet 15 permits a spring, not shown, to separate the clutch parts 14, and thrust the direct-drive clutch pin 10 into engagement. Belt tensioning.-The belts 22, 23 are pinned to the smaller pulleys at 24, 25, and are equally tensioned on the larger by loops 32A, Fig. 2, each passing through a hole in the pulley and drawn radially inwards by a bowed spring 35.

IPC: F16K31/06
Filed: 1970-02-11
Abstract: 1291765 Valves GUNSON'S SORTEX Ltd 1 Jan 1971 [11 Feb 1970] 6547/70 Heading F2V A sorting machine air ejector 10 comprises an inlet 15 leading to, and an outlet 21 leading from, a chamber 14, the outlet being controlled by a solenoid-operated valve and having connected thereto an outlet nozzle 24 which encloses a passage 22 terminating in an oblong aperture 27. The valve comprises a seat 30 having a central recess 32 surrounded by an annular upstanding flange 31 through which flange a plurality of ports 33 extend. A magnetic spring steel valve disc 34 is biased against the annular seat flange by the fluid pressure acting thereon, the presence of such bias being. ensured by the provision of an auxiliary outlet passage 43 connecting the passage 22 to atmosphere. Opening of the valve is effected by energizing a solenoid 42 and hence causing the valve disc to move upwardly along a reduced portion 35 of a hollow guide member 36. When in such open position, the valve disc engages a relatively thin, stainless steel protuberance 53 which acts to prevent contact between the disc and the solenoid casing 44. Furthermore, fluid then flows from the chamber 14 to the outlet ports 33 both directly and via the hollow guide 36 and recess 32.

The deflector 3 may be pivoted to the lid of the tank as shown in Fig. 5 and means provided such as a spring plunger 27 engaging notches 28 for retaining it in operative or folded-up position.
Patent GB-707608-A (GB)
Title: Process for the recovery of olefines from olefine-containing hydrocarbon mixtures
IPC: C07C7/171
Filed: 1951-03-19
Abstract: Olefines are obtained from a normally liquid olefine-containing hydrocarbon mixture, by fractionating the mixture to yield a fraction in which the hydrocarbons contain substantially the same number of carbon atoms per molecule, treating the fraction in the liquid phase at below 100 DEG  C. with hydrogen chloride in the presence of zinc chloride for the conversion of the olefines into alkyl chlorides, separating the alkyl chlorides from the saturated hydrocarbons by distillation; and eliminating hydrogen chloride from the alkyl chlorides in known manner.  The zinc chloride is used as a complex with the fraction to be treated or as an aqueous solution, preferably of above 50 per cent, e.g. 60-80 per cent concentration.  Aqueous solutions of zinc chloride are preferably used when the fraction contains aromatic hydrocarbons.  Preferably 5-10 per cent of zinc chloride is admixed with the olefine fraction before hydrogen chloride is passed.  Temperatures specified for hydrochlorination are 30-80 DEG  C. with the complex and 70-100 DEG  C. with aqueous solutions.  Preferably a continuous reaction is employed in which the reactants run concurrent over the catalyst.  An excess of hydrogen chloride is preferred. Advantageously dehydrochlorination is effected by treating the alkyl chlorides in liquid phase at approximately 180-250 DEG  C. with aluminium hydro-silicates, e.g. clay.  The hydrogen chloride thus liberated may be used in the addition stage. Aliphatic alcohols which may be present in the fractions, e.g. when derived from a Fischer-Tropsch synthesis, are also converted to pure olefines. In examples (1) a C10 fraction containing 30 per cent of olefines and 3 per cent of C7 alcohols is treated with hydrogen chloride at 20-70 DEG  C. in the presence of the zinc-chloride-olefine complex and the C10 mono-chloride thus obtained separated from C7 mono-chloride and hydrocarbons and dehydrochlorinated with "Tonsil" to yield C10 olefines; (2) a C8 hydrocarbon fraction containing 50 per cent of olefines is treated at 70-80  DEG C. with hydrogen chloride in the presence of aqueous 70 per cent zinc chloride to give a substantially olefine-free product; and (3) a C9 olefine fraction containing 38 per cent of olefines is treated at 80-85 DEG  C. with hydrogen chloride in a column of aqueous 65 per cent zinc chloride to give a substantially olefine-free product.

Filed: 1972-02-11
Abstract: 1344033 Surface condensers KRAFTWERK UNION AG 11 Feb 1972 [13 Feb 1971] 6631/72 Heading F4S  In an installation for condensing exhaust steam or other vapour from an industrial plant such as a steam turbine, chemical or other installation, the vapour is passed into a collecting chamber formed in the foundations of the installation and above which chamber is mounted air-cooled condensing elements for the vapour, these being connected to the chamber by pipes which also provide at least partial support for said elements. In steam condensing arrangements described, the said pipes support the condenser elements above the steam generating plant (i.e. as shown); or the exhaust steam from such a plant may be ducted into a collecting chamber (32, Fig. 4) in the foundations of a cooling tower, pipes (33) extending upwardly from the chamber (32) to support both the condenser elements (36) and the cooling tower shell structure (37, 38, 39). Fig. 1 shows an installation in which the condenser elements 12, their immediate supports 15 and steam distribution manifolds 11, as well as the fans 13 and their immediate supports 14, are all supported above the turbine 1, 2 and generator 3 by conduits 10 which extend upwardly from the steam collecting chamber 5 and have their lower ends secured in the plant foundations. Openings 17 in the conduits 10 connect these with the chamber 5. Exhaust steam from the turbine passes via a duct 4 into the chamber 5. The turbine installation is mounted on a platform 8 supported in a floor 22 on pillars 9. Condensate from the elements 12 flows through a tube 18 into a sump 19 and is removed therefrom by a pump 20 and conduit 21 to a further cooling circuit (not shown).

Abstract: 581,939. Aerials. STEVENS, A. H. (Lear Avia, Inc.). April 11, 1944, No. 6648. [Class 40 (v)] [Also in Group XXXVI] A loop antenna mounting comprising a streamlined shell of insulating material has its outer surface substantially covered with spaced strips of conducting material conforming with streamline flow past the shell, for the purpose of electrostatic screening. The loop antenna 15 is rotatably mounted inside the streamlined shell 10 which is mounted upon a base 11 with the interposition of a rubber gasket 36 and is constructed as described in Specification 580,568. The loop is driven by a motor 23 through gearing 25 and shaft 22 and a position transmitter 28 is provided. Connection to the rotating loop from leads 18 is made via contacts 45 and slip rings 43, 44, Figs. 4, 5 and 6 (not shown), formed by plating on annular projections on the insulating block 40 on which the loop is mounted. Electrically conducting strips 32 which may be of metal foil pasted on the shell or be formed by plating, are arranged over the surface of the shell 10 of insulating material. The strips are separated by spaces 33 and are longitudinally discontinuous to minimise eddy currents and are arranged to conform with the streamline flow past the shell so that wind currents, when the antenna is mounted on an aircraft in flight, exert pressure on the strips and assist them to hold firmly in their position. A strip 35 connects all strips 32 together and to earth potential. Specification 550,131, [Group XXXV], also is referred to.

Filed: 1972-02-17
Abstract: 1374263 Neopentyl esters IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Feb 1972 [12 March 1971] 6673/71 Heading C2C Esters of polyols containing a neopentyl group are prepared by reacting an olefine with carbon monoxide and an aliphatic monohydric alcohol (1-4C) in the presence of a Group VIII metal carbonyl catalyst and not more than 10% of a Lewis base, oxidizing the carbonyl in the reaction product with a gas containing free oxygen, fractionally distilling the product, and converting the ester to one with a polyol containing a neopentyl group by hydrolysis and esterification with the polyol or by transesterification with the polyol. Cobalt carbonyl is the preferred catalyst, with aliphatic amides, heterocyclic bases, nitriles and lactams as the Lewis bases. The ester may be converted by hydrolysing and re-esterifying with the polyol preferably with a catalyst such as alkyl titanate, or alternatively by transesterifying in the presence of a catalyst such as sodium isopropoxide or phenate. An example describes the reaction of octene-1 to form methyl nonanoate, followed by the formation of pentaerythritol tetranonanoate by esterification of the acid or transesterification of the methyl ester.
