Title: Manufacture of dyes and process for sensitising photographic silver halide emulsions
IPC: G03C1/12
Filed: 1936-05-11
Abstract: Cyanine and styryl dyes are made from 3-aryldihydrothiodiazoles of the general formula <FORM:0479926/IV/1> where R=aryl or substituted aryl and R<1>=H, alkyl or aryl. By condensation of these compounds with esters, e.g. methyl or ethyl iodide, dimethyl sulphate, methyl- or ethyl-p-toluene-sulphonate, the adjoining methyl group is rendered reactive so that the quaternary salts thus obtained may be treated in a solvent, e.g. pyridine or acetic anhydride with known condensing agents, e.g. p-dimethylaminobenzaldehyde, an alkyl ester of an ortho acid, such as ethyl ortho-formate or acetate, b -ethoxyacrolein acetal, diphenylformamidine, glutaconic aldehyde dianilide hydrochloride and the like.  The dyes are sensitizers for photographic emulsions and are used as alkyl chlorides, bromides, iodides, methyl sulphates or perchlorates. In examples: (1) and (2) 3 - phenyl - 5 - methyl - 2 : 3 - dihydrothiodiazole-(1 : 3 : 4)-methiodide is condensed with triethylorthoformate in acetic anhydride or with p-dimethylaminobenzaldehyde; (3) 2 : 2<1> - 5-trimethyl - 3 - phenyl - 2 : 3 - dihydrothiodiazole-(1 : 3 : 4) ethiodide is condensed with quinoline methiodide in alcoholic sodium alcoholate, (4) 3 - phenyl - 5 - methyl - 2 : 3 - dihydrothiodiazole-(1 : 3 : 4) ethiodide is melted with diphenylformamidine; the resulting product is suitable for making symmetrical and unsymmetrical carbocyanines by condensation with heterocyclic quaternary ammonium salts; (5) 2 : 2<1> : 5 - trimethyl - 3 - p - bromphenyl - 2 : 3 - dihydrothiodiazole-(1 : 3 : 4) ethiodide is refluxed with b -ethoxyacrolein acetal in pyridine.  The dihydrothiodiazoles may be made for example by condensing a -phenyl- or a -(substituted phenyl)-b -thioacetyl-hydrazines with aldehydes or ketones (see Bulletin de la Classe des Sciences de l'Acad<\>aemie Royale de Belgique, Vol. XIX 1933, page 543). Specification 457,450 is referred to.

Title: Open-weave endless fabric and process for producing such fabric
IPC: D06M15/41
Filed: 1961-04-14
Abstract: An open-weave endless fabric formed from yarns of a synthetic resin is coated sequentially with a thermosetting phenol-aldehyde resin and a thermosetting amino-aldehyde resin.  The preferred synthetic yarn is nylon, but others specified include acrylics, rayon, acetate, triacetate and polyesters.  The phenol-aldehyde resin, preferably containing an aldehyde-phenol molar ratio of less than 1 : 1 such as a novolac, is applied to the fabric and partially cured.  Resole resins having an aldehyde-phenol molar ratio of at least 1 to 1 may also be used.  The amino-aldehyde resin such as melamine-, urea- or substituted urea- or melamine-aldehyde resin may then be applied. The amino-aldehyde resin should contain sufficient available aldehyde to compensate for any deficiency of aldehyde in the phenol-aldehyde resin, thus bringing the molar ratio up to at least 1 : 1.  The phenolic component may be any mono- or poly-hydric phenol, preferably mononuclear such as phenol, phloroglucinol, resorcinol, orcinol, and o-, m- and pcresols.  The aldehyde may be any aldehyde containing up to 4 carbon atoms, especially formaldehyde: paraformaldehyde and hexamethylenetetramine, acrylic aldehyde and glyoxal may also be used.  The amine component may be urea, thiourea, melamine or aniline.  Methylated-melamine and -urea resins, and also ethylene urea-formaldehyde resins are also suitable.  After curing the coated fabric, the temperature may be raised in order to set the fibre from which the fabric is woven. Specification 827,754 is referred to.

Abstract: 687,049. Hydraulic dampers. CHRYSLER CORPORATION. June 7, 1951 [June 8, 1950], No. 13522/51. Class 108 (iii). In an hydraulic shock absorber comprising a piston E, cylinder 31, and reservoir D, the piston E has liquid flowrestricting passage means 57 connecting the cylinder chambers F and G above and below the piston E, and liquid flowrestricting escape means J connecting the chamber G and reservoir D, a check valve 63 providing free passage of liquid from the reservoir to the chamber G on outward movement of the piston from the cylinder. The passage means 57 comprises three circumferentiallyspaced passages, and the escape means J, a single passage of the same diameter as that of each of the passages 57. Excess pressure in the chamber G on the compression stroke, may be relieved by a valve V comprising two spring discs 51, 52 which seat over a circumferential channel 53 opening into large diameter passages 56. The valve V may be omitted, Fig. 6 (not shown). The check valve 63 is retained on its seat by spring fingers 69 and closes to confine liquid flow from the chamber G to the reservoir D, to the passage J. The ratio of the total area of the passages 57, to the area of the passage J, should preferably equal the ratio of the cross-sectional areas of the chamber F and piston rod 28. Typical dimensions and curves illustrating operation of the shock absorber are given. Specification 684,816 is referred to.

Title: Improvements in or relating to a phase sensitive device

Filed: 1964-04-01
Abstract: 1,042,074. Phase detectors. LABORATORY FOR ELECTRONICS Inc. April 1, 1964 [April 12, 1963], No. 13542/64. Heading H3A. An arrangement for indicating the phase difference between two signals comprises means for shifting the phase of one of the signals so that the phase of the shifted signal is in quadrature with the phase of the other signal and means for indicating the amount of phase shift. The first signal e 1  is applied via amplifier 15 to one input of a phase detector 19. The second signal e 2  is applied to two networks, the first of which introduces a phase lead of 45 degrees and the other a lag of 45 degrees. The output of the two networks is applied to opposite ends of a potentiometer which supplies a signal to the second input of the phase detector. This signal varies 45 degrees with respect of e 2  in dependence on the tap position and the output of the phase detector is amplified and drives a servo motor 23 to move the top to a position in which the detector output is zero and its input voltages are 90 degrees out of phase. The amount of phase shift and hence the phase relationship between the signals is indicated by a meter 27 which measures the D.C. voltage at the top position. The D.C. is supplied to the potentiometer from an external source via resistor 49.

Title: Improvements in or relating to impregnating compositions and to materials impregnated therewith

Abstract: 599,492. Impregnating compositions. SNOW, H. July 19, 1944, No. 13863. Convention date, June 15, 1943. [Class 140] An impregnating composition comprises the heat reaction products of a phenol formaldehyde resin, petroleum pitch having a boiling range beginning at about 450‹ F. and composed of polymerized olefinic hydrocarbons, a drying oil which modifies somewhat the hardness of the resin, and a petroleum distillate solvent, the proportions by weight of said constituents being approximately 2 parts of said resin, 4 parts of said pitch, 4 parts of said drying oil and 1 part of said solvent. In the example, the drying oil is chinawood oil and with the resin and the pitch is heated at a temperature of 300‹-550‹ F., usually about 425 until the consistency of a small soft ball is reached. A solvent, e.g. xylol, benzol or a petroleum thinner with some of the drying oil added is heated to about 150‹ F. and stirred into the product. The fabric is usually impregnated by a multiple dip procedure by passing slowly through a bath of the composition containing 60-64 per cent solid matter heated to about 110‹ F. and dried in festoons in air at 250‹- 300‹ F. The procedure is then repeated and the product allowed to age at room temperature. The resin is cured by heating the impregnated fabric in an oven at 275‹-280‹ F. for 24-36 hours. The material is calendered, surface ground and re-calendered. If a single dip is given, the impregnating bath is held at 140‹ F. and will contain a higher proportion of solid, e.g. 75-85 per cent or even 90 per cent. Suitable drying oils are linseed oil, chinawood oil, oiticia oil, perilla oil, soya-bean oil, dehydrated castor oil, cashew nut shell oil, and synthetic drying oils including the glycerides of clupadonic acid and similar highly unsaturated fatty acids. The synthetic drying oils may with advantage be added along with one of the vegetable drying oils. Specification 570,892 is referred to. The Specification as open to inspection under Sect. 91 also describes as alternative resins, ester gum, fused Congo gum, neutralized rosin, zinc resinates and modified, phenolic resins ; as alternative pitches, a relatively soft petroleum resin, stearine pitch, fish oil pitch and cottonseed pitch. This subject-matter does not appear in the Specification as accepted.
