Title: Omega [3-(1,2-dithiolanyl)] aliphatic acids, salts and esters and the preparation thereof
IPC: C07D339/04
Filed: 1953-04-09
Abstract: The invention comprises omega [3-(1,2-dithiolanyl)] aliphatic acids of the general formula <FORM:0762575/IV(b)/1> in which n is from 2 to 6, and their salts and esters.  The acids may be prepared by oxidizing a dithiol acid of the formula CH2(SH).CH2.CH(SH).(CH2)n.COOH e.g. using iodine in potassium iodide solution or air in the presence of ferric iron.  The dithiol acids (II) may be prepared by refluxing an omega thiol-hydroxy acid of the formula CH2(SH).CH2.CH(OH).(CH2)nCOOH with excess thiourea and a halogen acid, and hydrolysing the intermediate thiouronium salts with, for example, sodium hydroxide, followed by acidification.  The thiolhydroxy acid (III) may be prepared by reducing an omega-acetylthioketoester of the formula CH3.CO.S.CH2.CH2.CO.(CH2)n.COOR in which R is alkyl, with a metallic hydride reducing agent such as sodium borohydride or lithium aluminium hydride and hydrolysing the products.  The acetylthioketoester (IV) may be obtained by reacting an unsaturated ketoester of the formula CH2=CH.CO.(CH2)n.COOR with thioacetic acid. The unsaturated ketoester (V) may be obtained by dehydrohalogenating a b -halogen-substituted ketoester of the formula X.CH2.CH2.CO.(CH2)n.COOR, where X is halogen, for example by distillation at reduced pressure.  The halogen-substituted ketoester may be prepared by reacting an ester halide ROOC.(CH2)nCOX with ethylene in the presence of a metallic halide catalyst, preferably aluminium chloride.  The reaction may be effected by bubbling ethylene through a solution of aluminium chloride in the acid chloride, or by adding the acid chloride to a suspension of aluminium chloride in a solvent through which ethylene is passed.  Salts of the new products (I) are prepared by neutralization with alkali.  Esters are obtained by heating the acid (I) with an alcohol in the presence of an esterifying catalyst or by reacting with diazomethane or diphenyl diazomethane to give the methyl and benzhydryl ester respectively. The novel acids, salts and esters are useful as oxidation inhibitors and growth supporting factors for certain micro-organisms.  The 1, 2-dithiolanyl ring may be oxidized with t.-butyl hydroperoxide resulting in addition of one atom of oxygen to the disulphide ring whereas treatment with hydrogen peroxide results in two oxygen atoms being attached to the ring on either or both sulphur atoms.  A detailed example is given of the synthesis of omega-[3-(1,2-dithiolanyl)]-valeric acid starting from ethyl adipyl-chloride and by way of the intermediates D 7,6-keto-octenoate, 8-thiol-6-hydroxyoctanoic acid and 6,8-dithioloctanoic acid.  Ethyl succinyl chloride and ethyl glutaryl chloride are mentioned as starting materials for acids of formula (I) where n is 2 and 3 respectively.

Title: Fuel injection pumping apparatus
IPC: F02D1/10
Filed: 1972-03-02
Abstract: 1420749 Centrifugal governors SIMMS MOTOR UNITS Ltd 22 Feb 1973 [2 March 1972] 9692/72 Heading G3B Fuel injection apparatus for an I.C. engine is operable to ensure that a sudden increase in load does not result in an excessive decrease in speed. The apparatus comprises an injection pump 9 having a control rod 12, a centrifugal governor 13 for opposing the load of a spring 16 and operable, via a lever 15, to control the position of the rod 12, an operator controlled member 18 for adjusting the loading of the spring 16, and coaxial adjustable levers 22, 26 carrying a spring 27 engaging the operator controlled member 18 and being positionable for engagement by an abutment 21 on the rod 12. The apparatus is shown with the operator controlled member 18 in the idling position. On start-up the governor 13 causes the control rod 12 to move to the left to decrease the delivery of the pump 9. Thereafter clockwise movement of the member 18 moves a roller 17 along a ramp 19 to increase the loading of the spring 16 and thus move the rod 12 rightwards i.e. the fuel increase direction. This causes the abutment 21 to engage and turn the lever 22 before the rod 12 reaches the maximum fuel position as determined by an adjustable stop 25. Turning the lever 22, acts via an adjusting screw 24, to turn the lever 26 and thus stress the spring 27 which thereby assists the action of the governor weights. The stressing of spring 27 is against an abutment surface 28 on the member 13. The surface 28 is profiled so that, for a given speed, the maximum fuel is not, as hitherto, dependent on the position of the operator controlled member 18. In the event of a sudden increase in load and thus a sudden decrease in the force of the governor weights, the leaf-spring 16 immediately moves the rod 12 to increase the fuel supply by overcoming the spring 27 and allowing the lever to contact the maximum fuel stop 25. A further lever 23 is pivotable in a clockwise direction to move the rod 12 to the zero delivery position.

Title: Improvements in or relating to the treatment of cork
IPC: B27J5/00
Filed: 1948-04-07
Abstract: 663,169. Treating cork. ARMSTRONG CORK CO. April 7, 1948 [June 28, 1947; June 28, 1947], Nos. 9734/48 and 9735/48. Class 145 (i) [Also in Group VIII] A method for the industrial sterilization of compressed cork particles comprises expanding the compressed particles before final utilisation, e.g. by the application of heat, to regain their original density and remove the permanent set arising from their compression. The compressed particles, e.g. in the form of a bale used in transport or storage, are first disintegrated mechanically, and the resultant agglomerates heated in a dry oven at 100-250‹ F. for 1 to 3 days to restore them to their original density. In a modification, the heating time may be reduced to 12-24 hours by the addition of up to 10 per cent. by weight of a softening agent such as a polyhydric alcohol, e.g. glycerine or ethylene glycol, sugar solutions, water. According to a modified method, the entire bale is expanded and disintegrated by exposure to steam for about 15 to 30 seconds. The resultant cork particles may be mixed with a binder, such as glue, glue-glycerine, or rubber latex, and moulded to any desired shape. When the binder contains glycerine, the amount of glycerine added as a softening agent in the expansion process is kept below the total quantity required and the balance added later. Specification 250,878, [Class 145 (1)], is referred to.

Title: Improvements in or relating to moving diaphragm apparatus
Inventor: MARTIN RICHARD GEOFFREY
IPC: G01N21/37
Filed: 1954-04-05
Abstract: 774,123. Infra-red gas analysers. SHELL RESEARCH, Ltd. Jan. 31, 1955 [April 5, 1954], No. 9941/54. Class 40 (3). In apparatus such as an infra-red gas analyser in which a movable diaphragm is subjected to mechanical vibrations the inertia of a mass of gas is used to oppose vibrating movements of the diaphragm. In the gas analyser shown, two beams of infra-red radiation from a source 3 pass respectively through a sample tube 4 and a reference tube containing a normally adjustable shutter 5. A rotating shutter 10 interrupts the beams alternately and they then pass through guides 16 into a detector chamber 6 containing gas which expands and deforming diaphragm 8 which forms with fixed electrode 9 a condenser microphone. Difference in the beam intensities produces a D.C. output from a phase-sensitive amplifier fed also with a reference voltage developed by chopper 10 and a photo-cell. Surrounding the microphone is an annular compartment 7 in which is the same gas as fills compartment 6 but which is in free communication with the lower side of the diaphragm. The centre of gravity of this mass of gas is in compartment 6. Thus, when vibrations of the apparatus cause the diaphragm and gas in compartment 6 to move in one direction the gas in compartment 7 tends to move in the same direction and develops opposing pressure on the lower side of the diaphragm. A capillary leak 23 is provided between compartments 6 and 7 to prevent build up of static pressure differences but if the gas in compartment 7 is not the same as that in compartment 6 this leak is omitted.

Title: Silver halide emulsion and photographic sensitive material using the same
Inventor: UCHIDA MITSUHIRO
IPC: G03C7/30
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain a silver halide emulsion improved in storage stability and pressure resistance by subjecting it to reduction sensitization from the start of dislocation introduction to the end of grain formation. SOLUTION: It is preferred that flat silver halide grains having dislocation lines on the circumference of each grain amount to 100-70% of the projection areas of the total silver halide grains. The reduction sensitization is executed from the start of dislocation introduction to the end of grain formation, and silver nuclei for capturing positive holes contributing to incease of sensitivity can be formed. The grain formation is carried out in a silver nucleus stabilizing atmosphere and the reduction sensitization is made in the same atmosphere from the start of the grain formation or a time on the way of grain formation to the end of it in order to prevent production of instable silver nuclei. The silver nucleus stabilizing atmosphere is formed by the following methods; adding a radical scavenger, setting pH to 7-10, and restraining silver ion solubility to <=1.5×10<-6> .
