Patent GB-942324-A (GB)
Title: Electric switches
Inventor: NEVETT LESLIE JAMES
IPC: B60R16/00
Filed: 1960-08-15
Abstract: 942,324. Retractive switches. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 10, 1961 [Aug. 15, 1960], No. 28126/60. Heading H2B. A switch in which the operating member is arranged for rotary and axial movement has a spring-loaded contact arm pivotally mounted on a carrier which rotates with the operating member and cam means movable axially with the spindle to move the arm against the spring- pressure. As described in relation to a starter switch for a compression ignition engine, rotation of a knob 33 rotates a carrier 38 carrying two pairs of contacts 41, the contacts of a pair being connected to form a single bridging contact. Contacts such as 25 are arranged in a circle on the base 21 and in a first, or OFF, position the bridging contacts 41 complete no operative circuit. Rotation of the knob 33 and contacts 41 to the next or NORMAL position causes circuits to be completed to auxiliary apparatus, e.g. a radio. Further rotation, against a spring 51, to the third or START position completes also the circuit to the starter motor. Inadvertent movement of the switch between OFF and NORMAL positions is said to be prevented by means of projections 40 on the carrier 38 and corresponding projections 39 on a disc 36 fixed against rotation. In the central NORMAL position only, a projection 50 on the shaft 32 allows the knob 33 to be depressed, thus moving axially a cam surface 49 which engages a contact arm 43 pivotally mounted on the upper surface of the carrier 38. Bridging contacts 44 carried by the arm 43 are thus moved outward to complete the circuit to a starter aid such as an inlet manifold heater. Upon rotation of the knob 32 to the START position, the heater circuit is maintained and the starter motor circuit completed. When the knob 32 is released, spring 51 returns it to the central position and spring 34 then retracts it so that the switch regains its NORMAL position.
Patent GB-281281-A (GB)
Abstract: 281,281. Bensa, F., (Assignee of Zinke, A.). Nov. 26, 1926, [Convention date]. Chlorperylene quinones are obtained by treating octa-, nona-, deca-, undeca-, and dodecachloroperylenes with fuming sulphuric acid at a temperature of 130-180‹ C. Thereby some of the chlorine atoms are replaced by oxygen. whilst the remainder are retained; the products are vat dyestuffs. An example is given of the treatment of dodecachloroperylene, which yields a product dyeing cotton red from a red vat; on exposure to air, the colour turns olive green, and by subsequent treatment with salts of metals such as iron and chromium the colour becomes red to violet. Specification 232,264 is referred to. Octato dodeca-chlorperylenes are prepared by passing dry chlorine with a solution or suspension of perylene or a low-chlorinated perylene in an inert solvent such as nitrobenzene, to which an inorganic chloride such as aluminium or antimony chloride is added. Specification 288,171 is referred to.

Title: Improvements in high pressure radial piston pumps for liquids
IPC: F04B1/04
Filed: 1945-10-25
Abstract: 602,199. Radial piston pumps for liquids. PAUGET, G. Oct. 25, 1945, Nos. 28234 and 28235. Convention dates, Oct. 28, 1944 and June 19, 1945. [Class 102 (i)] In a radial reciprocating pump which may comprise two sets of pistons 1, 3 coupled in series, the pistons 1 are immobilized hydraulically in their uppermost position clear of their actuating eccentric 4 when the delivery pressure from the pump reaches a predetermined value. The 'piston 1 draws liquid from the central suction chamber 34 through the aperture 1b and delivers through the conduit 2a to the piston urging it back towards its eccentric 5 and delivering the liquid under pressure to. the chambers 2b which are all connected by conduits to a single delivery collector from which is led a conduit in communication with a control piston 23, Fig. 3. When the delivery pressure reaches a predetermined value the piston 23 is lifted against a spring 24 and permits liquid to pass through passages 2f which are interconnected by an external channel ring (not shown) to the cylinder space formed by the reduced diameter of the piston 1 raising the piston 1 to its uppermost position where it remains until a reduction in pressure allows the piston valve 23 to return to its lower position, the liquid in the cylinder space returning under the action of a spring 21 to the central suction chamber via the passages 2f, 2g and 2d. In a modification, the piston 1 operates in a bush of two diameters which is subject to the hydraulic locking action and when moving to its uppermost position carries with it the piston 1 by means of a cross pin at the same time releasing liquid from the cylinder by lifting the suction ball valve off its seat. In a further modification liquid under maximum pressure passing through the conduit 2f operates hemispherically-ended plungers which engage annular recesses in the pistons 1 when in their uppermost position ; on pressure release the plungers are pushed into their cylinders by downward thrust of the return spring of the piston 1.

IPC: C07C59/68
Filed: 1956-09-18
Abstract: Compounds of formula <FORM:0822199/IV (a)/1> in which the nucleus X contains one or more halogen atoms and/or alkyl groups and R1 is an alkyl group of not more than 8 carbon atoms, are prepared by condensing an alkali metal salt of a phenol of formula <FORM:0822199/IV (a)/2> with an ester of formula <FORM:0822199/IV (a)/3> in which R1 is as defined above, R is a cyano or carboalkoxy group and R11 is an alkylsulphonyl, benzenesulphonyl or substituted benzenesulphonyl group, and thereafter hydrolysing the resulting alpha-phenoxyalkanoic acid nitrile or alkyl alpha-phenoxyalkanoate. The condensation may be carried out by adding the ester to an aqueous or alcoholic solution of the alkali metal phenate at an elevated temperature and under alkaline conditions.  The nitrile or ester so obtained may be hydrolysed directly without preliminary isolation, for example by treatment with an alkali metal hydroxide solution, followed by acidification and filtration.  The esters of formula III may be prepared as a preliminary stage in the process of the invention.  The alpha-phenoxyalkanoic acids are used in herbicidal compositions. In examples: (1) alpha-cyanoethyl benzene sulphonate, prepared by reacting sodium cyanide and acetaldehyde in alkaline medium, followed by reaction with benzenesulphonyl chloride, is reacted with the sodium salt of 4-chloro-2-methylphenol, 2 : 4-dichlorophenol, 2 : 4 : 5 - trichlorophenol, p - chlorophenol, o-cresol or 2-bromo-4-chlorophenol, followed by hydrolysis with aqueous sodium hydroxide, acidification with hydrochloric acid and filtration to give alpha-(4-chloro-2-methyl-phenoxy) - or - (2 : 4 - dichlorophenoxy) - or -(2 : 4 : 5 - trichlorophenoxy)- or -(p - chlorophenoxy)- or -(p-methylphenoxy)- or -(2-bromo-4-chlorophenoxy)-propionic acid; (2) alphacyanoethyl toluene-p-sulphonate, prepared as in (1) but using toluene-p-sulphonyl chloride is reacted as in (1) with 4-chloro-2-methylphenol to give alpha-(4-chloro-2-methylphenoxy)-propionic acid; (3) alpha-cyanopropyl benzene sulphonate, prepared as in (1) but using propionaldehyde, is reacted with 2 : 4-dichlorophenol as in (1) to give alpha-(2 : 4-dichlorophenoxy)-butyric acid; (4) alpha-carboethoxyethyl benzenesulphonate or toluene-p-sulphonate, prepared by reacting ethyl lactate with benzenesulphonyl chloride or toluene-p-sulphonyl chloride in the presence of pyridine, is reacted with the sodium salt of 4-chloro-2-methylphenol and the product hydrolysed, acidified and filtered as in (1) to give alpha-(4-chloro-2-methylphenoxy)-propionic acid; (5) alpha - cyanoethyl methanesulphonate, prepared by treating lactonitrile in pyridine with methanesulphonyl chloride, is reacted as in (1) with 4-chloro-2-methylphenol to give alpha-(4 - chloro - 2 - methylphenoxy) - propionic acid.

Title: Improvements in and relating to apparatus for desuperheating steam
IPC: F22G5/12
Filed: 1937-10-23
Abstract: 498,083. Fluid - actuated valves. AULD & SONS, Ltd., D., and GRAHAM, D. A. Oct. 23, 1937, Nos. 29020 and 35965. [Class 135] [Also in Group XII] A steam desuperheater comprises a passage 41, 42 controlled by a mushroom or disc valve 45 carried by a spindle 46 and co-operating with seats 43, 44, and a passage 52, 54, 61 in the valve spindle and valve whereby water is fed to and atomized by the steam in passing through a zone or zones of high velocity, the spindle being loaded so that the steam velocity remains constant and also being operatively connected with a water valve 68 opening and closing with the steam valve to regulate the water supply in accordance with the volume of steam. The valve may function as a reducing valve maintaining the steam pressure on the delivery side constant by the provision of a casing 48 within which an extension 46b of the valve spindle carries a flexible diaphragm 49 subjected to the pressure of a water column and of the steam in the low pressure zone 42 against a spring-loaded lever 50 which tends to raise the valve. Water is fed to the needle valve 68 through a filter 66 and pressure reducing valve 67 and thence through a pipe 69 to the valve passages and radial outlets 61, 65, the needle valve being controlled by a lever 70 linked to a lever 74 connected to the lower end of spindle 46b. The water supply through valve 68 may be augmented by a smaller supply introduced through a thermostatically controlled valve 81 and pipe 82 so that variation of temperature in the delivery side of the desuperheater effects a relatively fine regulation of the water supply. In modifications water is delivered through a number of annularly arranged passages in the valve seat or seats, one such construction embodying a valve tending to be depressed against its seat by a weight carried by a lever extending through a yoke on the valve spindle, a needle valve controlling the water supply being connected to the lever so that water is admitted in correspondence with the amount of steam passing through the desuperheater.
