Title: Improvements in or relating to straps and especially wristlet watch straps
IPC: A44C5/16
Filed: 1947-04-09
Abstract: 628,865. Attaching articles to person. ORLO LEATHER GOODS, Ltd., and ULLMAN, F. E. April 9, 1947, No. 9385. [Class 43] Means for attaching straps to a wrist watch comprise a flexible cordlike member which is passed through the watch loop, is doubled back on itself, and has its ends detachably gripped in a clamp, which comprises a U-shaped channel member having a loop round which one of the straps is secured, one limb of an L-shaped member pivoted in the channel member being provided with gripping serrations, the other limb forming a lever which can be raised or lowered to release or grip the cord-like member. Two short straps 10, 11, of leather or the like, having the usual buckle 12 and perforations 13, are each attached to a metal clamping device by means of a loop 14 provided in an extension of the latter. The clamp consists of a U-shaped member 15 in which is pivoted an L- shaped member, one limb 16 of which has gripping serrations, the other limb 17 constituting an operating lever ; the base of the member 15 is shaped to provide two shallow channels 18, 19. A thin cord 20, 21 of textile material, leather, plastic or the like, is threaded through each watch loop and is doubled back on itself, after which its ends are inserted in the channels 18, 19 of the clamp, the lever 17 and hence the serrated part 16 of which have been raised. The lever is then pushed down so that the serrations grip the ends of the cord. A sliding metal or like encircling band 22 holds the cord lengths close together.

Title: Process for the production of high molecular weight polycarbonates
Filed: 1956-03-26
Abstract: In the manufacture of fibre- or film-forming polycarbonates (a) by interesterifying a dialkyl-, dicycloalkyl- or diaryl-carbonate or a dialkyl-, dicycloalkyl- or diaryl-dicarbonate of an aromatic dihydroxy compound with an alkyl-, cycloalkyl- or aryl-dihydroxy compound; or (b) by polycondensing a dialkyl-, dicycloalkyl-or diaryl-dicarbonate of an aromatic dihydroxy compound alone, reaction is effected in the presence of a basic catalyst which is neutralized in the course of or at the end of the interesterification or polycondensation by adding a base-binding material to the melt.  A large number of reactants are referred to.  The basic catalyst may be an alkali or alkaline earth metal or an alcoholate, phenolate (e.g. of phenol or a dimono-hydroxyaryl alkane), hydride, oxide, amide or a basic reacting salt thereof (e.g. acetate, benzoate or carbonate). The base-binding material may be an aromatic sulphonic acid, an organic acid halide, an organic chloroformate, a dialkyl sulphate, an organic chlorine compound or an acid salt of a polybasic inorganic acid.  Preferably volatile base-binding materials are used and excess thereof is removed from the polycarbonate under reduced pressure. Examples describe the production of polycarbonates from (1) hexane diol and diethyl carbonate; (2) 2,2-di-(p-hydroxyphenyl) propane and diphenyl carbonate; (3) bisphenyl dicarbonate of 2,2-(p-hydroxyphenyl) propane and 2,2-di-(p-hydroxyphenyl) propane; (4) 2,2-di - (p - hydroxyphenyl) butane and diphenyl carbonate; (5) 2,2-di-(p-hydroxyphenyl) propane and di-o-cresylcarbonate; (6) bis-phenyl-carbonate of 2,2-di-(p-hydroxyphenyl) propane; (7) bis-phenylcarbonate of 2,2-di-(p-hydroxyphenyl propane and the bis ethylcarbonate of 2,2 di-(p-hydroxyphenyl) propane; (8) bis-phenylcarbonate of 2,2-di-(p-hydroxyphenyl) propane and 2,2-di-(p-hydroxyphenyl) propane; (9) bis-phenyl carbonate of resorcinol.  Specifications 650,002, 772,627, 808,485, 808,486, 808,487 and 808,489 are referred to.

Title: Improvements in the adhesion of phosphor powders to the glass envelopes of fluorescent lamps
Inventor: ANDERSON JAMES THOMSON
IPC: C09K11/02
Filed: 1951-04-24
Abstract: In a process for applying a coating of a powdered phosphor to a surface of a glass envelope of a fluorescent lamp by flowing over the surface a suspension of the phosphor in a viscous solution which serves as a binder for the phosphor, allowing the suspension to drain away and the coating left on the surface of the envelope to dry, followed by subjecting the envelope and coating to a firing process to remove the binder, the borate radicle is added to the suspension in the form of a salt or ester of an organic base which is soluble in the solvent employed in the viscous solution.  The latter may comprise nitro-cellulose dissolved in amyl acetate, in which case amyl borate is added to the amyl acetate.  The known use of boric acid in the suspension to increase the adhesion of the powdered phosphor to the surface is referred to, and the Provisional Specification states that instead of boric acid, boric anhydride is satisfactory with many phosphors.

Abstract: 1,211,062. Preparing enriched rice. KYOWA HAKKO KOGYO K.K. 21 Feb., 1969 [22 Feb., 1968], No. 9615/69. Heading A2Q. A process for preparing enriched rice grains comprises first soaking rice grains in water, steaming the soaked grains, drying the steamed grains, soaking the steamed and dried grains in dilute acetic acid, drying the soaked grains, thereafter soaking the grains in an aqueous solution containing a high concentration of an amino acid and then drying the thus treated grains. Preferably, the first soaking of the grains in water is for a period of 3 to 15 hours, this being followed by steaming for 10 to 20 minutes. The rice grains are then dried at 40‹ to 90‹ C., after which they are soaked in a 2 to 5 per cent by weight solution of acetic acid for 2 hours at a temperature of from 20‹ to 60‹ C., the grains being subsequently dried at 40‹ to 60‹ C. Prior to soaking in the acetic acid solution the rice grains may be roughened and/or milled. The animo acid for the final soaking is preferably at 40 to 60 per cent by weight solution of a lysine, e.g. lysine hydrochloride, sulphate, phosphate or glutamate, or threonine or tryptophane or a solution of a mixture of these, the soaking being continued for from 5 to 12 hours at a temperature of from 10‹ to 30‹ C. After the final soaking, the rice grains are washed with water and dried at a temperature above 40‹C. in an air stream or under reduced pressure.

The coal is gathered by arms 51, 52, which are pivoted in across-head 42 and pivotally connected to the piston-rods 61, 62 of cylinders 57, 58. The cross-head 42 is secured to the end of the piston-rod 41 of a cylinder 38 and is connected to guide-rods 53, 54 which move in guides 55, 56 on the cylinder. The cylinders 57, 58 are pivotally connected to the rods 53, 54, and are connected by flexible pipes to valves mounted on the forward end of the cylinder 38. By means of these valves, pressure fluid can be admitted to either end of the cylinders 38, 57, 58, or these cylinders connected to exhaust, to move the arms 51, 52 apart or together and to extend or retract the piston-rod 41. The cylinder 38 is connected by an horizontal pivot to lugs 36 upstanding from a plate 31 carried by a stem 30 mounted in a pillar 17.

Abstract: In a purification process of communal, industrial and esp. of organic matter contg. effluents removal of phosphorous is enhanced by biological means, allied to chemical treatment. Effluents brought into contact with active sludge are subjected to anaerobic, followed by aerobic and/or anoxic and/or other treatment. Necessary stoichiometric quantities of chemicals are added in a section of a reactor found after the anaerobic stage reactor. It is typical of the process, that chemicals are added only in such an equiv. prepn. that are necessary, to achieve a required purification level, following completion of a biological treatment stage. In terms of periods of time, chemical treatment is the last phase of the anaerobic treatment period. In terms of spatial distribution chemical treatment occurs in the first sector of the reactor placed immediately after the anaerobic compartment. It is an important feature of the reactor that it is compartmented.
