Title: Manufacture of derivatives of 1: 4: 5: 8-naphthalene-tetracarboxylic acid
IPC: C07D471/06
Filed: 1930-09-26
Abstract: Derivatives of 1 : 4 : 5 : 8-naphthalene tetracarboxylic acid are obtained by condensing equimolecular proportions of a salt of the said acid or its monoanhydride with an aromatic monoamine or salt thereof, whereby the dicarboxylic acid arylmonoimides or their anhydrides are obtained, or with an aromatic o-diamine, or a salt thereof whereby naphthoylene arylimidazole-peri-dicarboxylic acids or their anhydrides are obtained, in presence of a suitable solvent or diluent.  According to examples, the alkali metal salt of the tetracarboxylic acid or its anhydride is prepared in aqueous solution and condensed with o-diaminobenzene, 4-methyl-1 : 2-diaminobenzene 4-ethoxy 1 : 2 - diaminobenzene, 1 : 2 - diaminonaphthalene, 5-chloro-4-methyl-1 : 2-diaminobenzene, 4-bromo-1 : 2-diaminobenzene, 3 : 5-dibromo and 4 : 5-dichloro-1 : 2-diaminobenzene, o-toluidine, p-chloraniline, b -naphthylamine.  In the case of o diamine a diamino-diphenylimide is obtained as a bye-product in some cases. In place of the alkali salts, the pyridine or ammonium salt of the tetracarboxylic acid may be used.

Abstract: 1,109,326. Friction gearing. WERKZEUGMASCHINENFABRIK GILDEMEISTER & CO. A.G. 28 June, 1966 [30 June, 1965], No. 28975/66. Heading F2Q. [Also in Division B3] The jaws of a chuck 1, Fig. 2, are actuated when the chuck is disconnected from the main drive, by means 10, 10a which are engaged at rotational positions in the chuck determined by a drive means 7, 8. Dogs 10 mounted on a rotary spindle 4 drive dogs 10a in the chuck, and a friction wheel 5, keyed to the spindle, drives a friction roller 7 which co-operates with a groove 8 on the chuck. The groove has recesses 9 on its periphery, one for each set of dogs 10a. In operation with the chuck disconnected from its main drive, spindle 4 rotates, so that roller 7 rotates the chuck, until it drops into a recess 9, thus locking the chuck in the required angular position. Dogs 10, 10a engage, and the chuck jaws are actuated. In a modification, wheel 5 and roller 7 are formed with gear teeth.

Title: Inorganic sulphur compounds
Inventor: ROBERTS HUGH LEITHEAD
IPC: C01B17/46
Filed: 1959-08-25
Abstract: A mixture of sulphur-fluorine-oxygen compounds containing disulphur decafluorodioxide, SF5-O-O-SF5, disulphur decafluoromonoxide, SF5-O-SF5, and minor amounts, e.g. less than 10%, of compounds SF5-(O-SF4)n-OSF5, where n is 1, 2, or higher, is prepared by subjecting a mixture of sulphur chloride pentafluoride, SF5Cl, and O2 to U.V. light under anhydrous conditions.  1-6 moles SF5Cl are used per mole O2.  The volatile products are condensed, refluxed with NaOH or KOH, and then the nonaqueous phase is fractionally distilled.  In continuous operation, the volatile products, before condensation, are scrubbed, with saturated ferrous sulphate solution, acidified with sulphuric acid, and unchanged reactants are recycled.

Title: Noise reduction in phase shift carrier ware modulation systems
IPC: H04B14/00
Filed: 1954-10-08
Abstract: 752,628. Frequency modulation. BOSE, J. H. Oct. 8, 1954 [Oct. 12, 1953], No. 29062/54. Drawings to Specification. Class 40 (5). Relates to frequency modulation transmitters in which a phase shift modulator is followed by a frequency multiplier and a band-pass filter. In such an arrangement the effect of random phase shifts in the early stages, which introduce noise, is reduced by using a band-pass filter which attenuates desired high side frequencies, a compensating network being provided in the modulation input circuit. The invention is described as applied to a multiplex system in which further channels are added by subsequent modulations of the modulated carrier by modulated sub-carriers. Specifications 668,030 and 670,967 are referred to.

Abstract: 951,224. Egg cartons. MICHIGAN CARTON CO. Aug. 14, 1961, No. 29301/61. Heading B8P. A cellular egg carton (Fig. 1) is folded up from a single blank and comprises longitudinal side walls 10, 10a, bottom panels 23, a central ridge portion 21 and transverse walls 17, 18 providing egg receiving cells, transverse walls 17 are secured by tongues 28 produced by slit 27 extending through slots 31 of tongues 30 of the transverse walls 17, the V-shaped slits 45 assisting stability, transverse walls 18 are secured by tongues 37 on ridge 21 mating with slot 38 of wall 18. The transverse end walls 18 are taller than transverse walls 17 but both are held by parts 19, 19a which also provide locking tabs for tongues 16 on flap 15 of lid 13 of the box. The walls may also be strengthened by tabs 32 extending through slots 33 in the side walls 10, 10a. Perforation lines 44 are provided so that a carton holding one dozen eggs may be divided into two half-dozen size cartons. A series of slits 40, consisting of a cross-shaped slit 40a, downward, 40b and upward, 40c, arcuate members, in the base of the box provides support for carrying the eggs.

Title: Improvements in and relating to devices for the perfusion and transfusion of blood
IPC: A61M5/165
Filed: 1965-07-12
Abstract: 1,077,157. Blood transfusion device. J. RAZIMBAUD. July 12, 1965 [July 10, 1964], No. 29395/65. Heading A5R. A blood transfusion or perfusion device comprises a blood storage receptacle having a piercable wall, a dispensing receptacle for blood drawn therefrom having a needle attached to and in communication with its interior, and a housing for the piercing end of the needle, rigidly attached to the storage receptacle, and slidably attached to the dispensing receptacle so that axial movement of the receptacles relative to each other causes the needle to pierce the storage receptacle. The device is typically illustrated by Fig. 2, wherein the needle housing 1 is closed by a piercable membrane 4, this face being affixed to a storage receptacle at 5. The narrow portion 3 of the housing widens to a skirt 2, which is mounted in an annular recess 6 in an upper extension 7 of the dispensing receptacle 8. Two diametrically opposing lugs 10 on the skirt engage in cam slots in the outer wall of the recess, each slot having a horizontal part 12 followed by a vertical part 13, an inclined part 14 and another horizontal .part 15. The needle 17 is attached within a central bore 16, and enters the interior of the dispensing receptacle 9. The other end of this receptacle is closed by a cap 22, which may carry a blood filter 25, and is suitably connected, via 23, to a flexible tube and cannula. The skirt may further be sealed, and its attachment to the receptacle 8 lubricated, by bactericidally impregnated viscous material at 21. By rotation of the blood storage receptacle, the attached needle housing rotates relative to the dispensing receptacle, and the lugs move out of portion 12 of the slots to unlock the members. Axial movement of the housing 1 towards the dispensing receptacle 8, the lugs moving in portion 13 acting as a guide, causes the needle to pierce the storage receptacle, when blood flows through the needle into the dispensing receptacle. Further axial and then rotational movement brings the lugs into portion 15 of the slots, thus locking the members in the operating position.

Headings F2G and F2P A socket at the end of a pipe of moulded plastics material, such as P.V.C., for receiving a spigot of an adjacent pipe length comprising two moulded parts, one being a main pipe length 1 and the other being an extension piece 2 which is a snap-fit on one end of the main pipe length, is provided with a sealing ring 11 located in groove formed partly by said main pipe length and partly by said extension piece which together nip the sealing ring in position. The arrangement particularly permits a pipe length to be formed with a smaller bend radius than normally produced by moulding. The main pipe length end is provided with a flange 3 defining a tapered periphery 5 and a rearfacing shoulder 4. The extension piece is a progressively tight sliding fit over the flange until an internal lip 7 on the extension piece snaps over the rear-facing shoulder. In this position, the rubber " D " section sealing ring 11, initially positioned in the extension piece, is gripped between the wall 9 of the extension piece and the extreme end face of the main pipe length. An internal shoulder 8 on the extension piece limits the sliding movement on the main pipe length and a tapered internal flange 6 on the main pipe length provides an abutment for an inserted spigot end of an adjacent pipe length. Two external flanges 12 (one only being shown) form locating means for a strap fastening enabling the pipe to be secured to a support.
