Abstract: 1,186,336. Valves. GRAY CO. Inc. 13 May, 1968 [15 May, 1967], No. 22612/68. Heading F2V. [Also in Division F1] A valve for venting the actuating chamber of a compressed air-actuated diaphragm pump (see Division F1), comprises a resilient valve disc 52 with a central portion engaging a seat 57 and an outer portion engaging a seat 58. Alternatively valve disc 52 may be replaced by two piston-type valves. In operation, when the air pressure in the actuating chamber acting through port 56 rises above a predetermined pressure, the central portion of the valve disc is moved away from seat 57 against spring 65 to expose the outer portion of the valve disc to pressure. The whole valve disc is then moved to the right against springs 65 and 62 to vent port 56 to atmosphere via port 22. When the pressure at port 56 drops to a predetermined pressure below the opening pressure, the valve disc is moved by the springs to its closed position. Spring 65 is stronger than spring 62, both springs being adjusted by screw 55 to set the operating pressure.

Title: Improvements in or relating to the preparation of methacrylic compounds
Inventor: MCCONNELL GEORGE
IPC: C07C51/50
Filed: 1960-06-29
Abstract: Methacrylic acid amide and/or a sulphuric acid derivative thereof is prepared by the treatment of acetone cyanohydrin with sulphuric acid, oleum or chlorosulphonic acid in the presence of a stabiliser consisting of a compound having the ring structure, <FORM:0942318/C2/1> wherein X stands for sulphur, oxygen or nitrogen. The stabilizers may be phenothiazine, phenoxazine, phenazine or derivatives thereof, such as compounds containing those substituents which do not assist oxidation or polymerisation under the reaction conditions e.g. chloro, alkylcarboxy, hydroxy, amino and alkyl amino groups, also compounds which are quinanoid derivatives in these series for example methylene blue.  The stabilizer may be added as a powder, suspension or solution to the acetone cyanohydrin or the acetone used to prepare the cyanohydrin. The amount of stabilizer added is preferably 0.001 to 0.2% by weight of the total reaction mixture or 0.003 to 0.6% by weight of the acetone cyanohydrin.  Other known additives such as hydroquinone may also be added.  The methacrylic amide may be further reacted with an alcohol such as methanol ethanol, or butanol to form the methacrylic ester, desirably in the additional presence of the other known stabilizers.  The esters are purified by distillation from the additives. The amide may alternatively be hydrolysed to methacrylic acid. Examples illustrate the amide forming reaction using as stabilizers phenothiazine, methylene blue, 3 methoxy phenothiazine, 3 chloro-7-nitro phenothiazine, 10 carbo-ethoxy-phenothiazine, 10 acetyl-phenothiazine, phenothiazine-5-oxide, 10-ethyl-phenothiazine, 7 aniline-9-methyl-3 ono-1.2.4 trichloro-3 hydro phenothiazine, phenonazine, or phenazine, and conversion of the products into the methyl esters by refluxing the reaction mixture with methanol in the presence of water or steam. Comparative experiments illustrate the reaction without stabilization or with hydroquinone resulting in higher polymer formation.

Title: Improvements in or relating devices for folding moving articles
IPC: D06F89/00
Filed: 1958-07-17
Abstract: 871,970. Folding fabrics. ZEPHYR LAUNDRY MACHINERY CO. July 17, 1958 [July 24, 1957], No. 22994/58. Class 42 (2). A device, for folding moving articles, comprises an article sensing device arranged to control an electrical impulse unit for applying electrical impulses to an electronic counter at one rate per unit of travel of one of the articles, while the article is passing through a fixed position and at a higher rate after the article has passed the fixed position, the electronic counter being arranged to emit an electrical output signal on receiving a predetermined number of the electrical impulses for initiating folding of the article. In the arrangement shown an article 12 to be folded is fed along a belt 10 driven by roller 13. As the leading end of article 12 reaches switch 23 an electric circuit is completed by the switch to start an electronic counter counting at a predetermined rate. When the article has completely travelled under the switch 23 the electric circuit is arranged so that the counter then counts at a higher predetermined rate. When a predetermined total count is reached the electric circuit operates solenoid 16 to move the folding blade 15 so as to tuck the article 12 between the parallel runs of belts 10 and 11 and thereby fold the article. The counting rates are determined in relation to the speed of the belts and the distance of the switch 23 from the blade 15 is so chosen to give the fold in the required place. The total number of counts is proportional to the number of counts per inch of conveyer travel and to the distance between the switch 23 and the blade 15 and independent of the length of the article to be folded. In order to cope with closely following articles a second counter may be provided and the circuit arranged so that the first counter controls the blade 15 in response to alternate articles whilst the second counter controls the blade 15 in response to the articles in between.

Title: Process for hydrogenating aldehydes
Inventor: GWYNN BERNARD HENRY
IPC: C07C29/141
Filed: 1955-08-10
Abstract: Aldehydes are preferentially hydrogenated in a mixture of aldehydes and olefines by hydrogenating the mixture at a temperature below 260 DEG  C. and at a pressure of 7 to 70 kg. sq. cm. in the presence of added water using a hydrogenation catalyst, which is effective at temperatures below 260 DEG  C., whereby the aldehydes are converted to the corresponding alcohols and hydrogenation of the olefines is appreciably inhibited.  Suitable catalysts are, for example, nickel, cobalt, nickel tungsten sulfide, cobalt molybdate and copper chromite and they can be used in pelleted or granulated form as such or deposited on a carrier such as diatomaceous earth or kieselguhr.  The water may be introduced in liquid or vapour phase to the mixture of aldehydes and olefines before or after the mixture is introduced to the hydrogenation stage.  The mixture of aldehydes and olefines used as starting material is usually obtained by removing carbon monoxide, hydrogen and catalytic metals from the product obtained in the hydroformylation stage of the oxo process.  It is preferred to use liquid volume ratios of water to hydroformylation products of from 0.15:1 to 2:1.  In the examples, the product obtained by the hydroformylation of heptanes, consisting mainly of aldehydes and olefines, is hydrogenated in the presence of added water at a temperature below 260 DEG  C. and a pressure of 35 kg./sq. cm., using a nickel or kieselguhr catalyst, to give the corresponding alcohols, the olefins present in the starting material being largely unaffected by the hydrogenation.

Abstract: 1431244 Pistons and cylinders; valves ATWOOD & MORRILL CO 24 May 1974 [21 June 1973(2)] 23265/74 Headings F2T and F2V In a piston and cylinder combination, which may be used in a balanced poppet valve, Fig. 4, a gap is left between the edge 48 of a piston sealing ring 42 and the cylinder wall 24 in the upper part of the cylinder and sealing is only effected when the piston moves to the lower and narrower part of the cylinder. The sealing ring 42 may be of flexible metal. The combination is employed as piston 132 and cylinder 137 in Fig. 4. A main valve poppet 130 is opened by introducing compressed air into cylinder 154 to raise valve stem 152 and compress compression springs 138. To avoid compressing fluid in cylinder 137, stem 152 lifts pilot valve poppet 166 off its seat 164 before moving the poppet 130. The fluid in cylinder 137 escapes through ducts 194. Poppet 130 is closed by the action of springs 138, on releasing the compressed air from cylinder 154. A rapid downward acceleration of poppet 130 causes poppet 166 to be lifted, so that excess fluid pressure in cylinder 137 may be released through ducts 194, rather than causing damage to the main poppet by slamming it down on its seat 126.
