Patent GB-641459-A (GB)
Title: Improvements in or relating to coloured cellulose ester or ether textile materials
IPC: D06P1/649
Filed: 1948-02-23
Abstract: An acyclic amidine of a carboxylic acid containing an aryl group is incorporated in spinning solutions from which cellulose esters or ethers, e.g., cellulose acetate, are spun.  Amidines specified are N-phenyl-benzamidine, N-(o-, m-or p-)-tolyl-benzamidine, N-(p-methoxyphenyl)-benzamidine, N,N1-diphenyl-benzamidine, N-methyl-N-phenyl-benzamidine, N-phenyl-p-methoxy-benzamidine, N-phenyl-p-methyl-benzamidine, and the amidines of phenylacetic acid and alpha- and beta-naphthoic acids, e.g. N-phenyl-alpha-naphthamidine.ALSO:The resistance of dyeings on cellulose ester or ether fibres to the effects of the combustion products of coal gas is improved by incorporating in the fibres an acyclic amidine of a carboxylic acid containing an aryl group.  The amidine may be incorporated before, during or after dyeing, and is of particular value when dyeing with 1-amino-4-hydroxy-anthraquinone, 1,4-diamino-anthraquinone or a nuclear or N-alkyl or N-aryl substitution product thereof.  Amidines specified are N-phenyl-benzamidine, N-(o-, m- or p-) tolyl benzamidine, N - (p - methoxy - phenyl)-benzamidine, N,N1 - diphenyl - benzamidine, N - methyl - N - phenyl - benzamidine, N-phenyl - p - methoxy - benzamidine, N - phenyl-p - methyl - benzamidine, and amidines of phenylacetic acid or alpha- or beta-naphthoic acids, e.g. N-phenyl-alpha-naphthamidine.  The amidines may be incorporated in the fibres amounts ranging from 0.25 to 2 per cent and may be applied from aqueous dispersion or as an aqueous emulsion of a solution of the amidine in a water-insoluble liquid, e.g. benzene, toluene or xylene, or alternatively as a solution in an organic liquid having swelling properties for cellulose esters or ethers, e.g. aqueous methyl, ethyl or propyl alcohols of 50 to 70 per cent strength.  They may be applied before, during or after dyeing; conveniently, an aqueous dispersion containing both the amidine and the dyestuff may be used.  In examples: (1) cellulose acetate is dyed in a bath made by adding a paste of N-phenyl-benzamidine to a solution of Turkey Red Oil and adding the suspension obtained to a suspension of 1,4-di-(methylamino)-anthraquinone in soap solution, and (2) cellulose acetate fabric dyed with 1,4-diamino-anthraquinone is padded with a solution of N-phenyl-benzamidine in aqueous methylated spirit.

Patent GB-879374-A (GB)
Title: Process for the manufacture of compounds containing nitrogen and sulphur
IPC: C23F11/16
Filed: 1958-02-19
Abstract: Organic nitrogen and sulphur containing compounds, assumed to be heterocyclic, are prepared by reacting alkylidene vinylamines of formula <FORM:0879374/IV (b)/1> where R represents hydrogen or alkyl with sulphur or polysulphides, such as ammonium polysulphide.  When sulphur is used, elevated temperatures not exceeding about 200 DEG C. are used, but with polysulphides, the reaction commences at room temperature and the temperature should not exceed 100 DEG C.  In some cases, two nitrogen- and sulphur-containing products are obtained, one having approximately twice the molecular weight of the other.  A solvent such as dimethyl formamide may be used.  The alkylidene vinylamide may be prepared in situ by introducing ammonia into a mixture of a carbonyl compound and the sulphur or polysulphide. The products are stated to be of use as medicaments, corrosion and oxidation-inhibitors, vulcanising media, fungicides and pesticides. Examples describe the preparation of products from i-butylidene-b b - dimethylvinylamine (which is sometimes prepared in situ from i-butyraldehyde and ammonia) and i-hexylidene-b -methyl-b -propylvinylamine.  Picrates of the products are prepared.  Reference is also made to products derived from the mixtures of aldehydes derived from the catalytic hydrogenation of C7-9 alcohols occuring as by-products in the catalytic production of isobutanol from carbon monoxide and hydrogen.

Abstract: 1366972 Impact shock absorbers TOYOTA JIDOSHA KOGYO KK 7 Feb 1972 [19 Feb 1971] 5553/72 Heading F2S An impact shock absorber for mounting a vehicle bumper (not shown) comprises a cylinder 4 containing liquid in a chamber bounded by a sliding partition 6, and three impact energy absorbing members-a first member 1 formed with an orifice 103 and disposed in the chamber, a second member 5 whose outer surface can frictionally engage the inner wall of the cylinder, and a third member being a spring 7 (or coil spring 71, Fig. 5, not shown) disposed in the cylinder to resist movement of the sliding partition 6. On impact, as the piston-rod 2 moves into the cylinder, liquid passes through the orifice 103 in the piston 1 from the chamber 42 to the chamber 41. If the pressure in chamber 42 builds up the piston 1 wedges the member 5 (which is formed in four pieces, Fig. 2 (not shown), or with a slit, Fig. 3 (not shown) radially outwardly against the cylinder wall to exert a frictional effect. The back pressure produced in the chamber 41 because of the increased pistonrod volume acts via the sliding partition 6 on a rubber spring 7 in an air chamber 43. On further compression of the shock absorber a member attached to the piston-rod compresses a rubber stop 8. In Fig. 5, impact is applied to the shock absorber via a push rod (22) having a protuberance (23) which bears on the frictional/ energy absorbing member (52) which is in an air chamber. The orifice bearing piston (11) is connected to a wedge-shaped member (111) which actuates the friction member (52). Graphs of load against stroke are given (Fig. 8, not shown).

Filed: 1926-02-27
Abstract: 252,674. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Obergfell, H. F.). June 1, 1925, [Convention date.]. Impulse transmitters of the finger-hold type for telephone systems have a dial 14 formed as a thin stamping with all edges turned over, and are provided with an instruction card assembly, consisting of a transparent disc 4 and a card 5 held between a locking ring 1 and disc 6, which can only be removed from the dial by a special tool and then comes away as a unit. The card is locked in the ring 1 by turning the disc 6 to carry notches 8 away from teeth 24, 24<1>, and to bring a tongue 18 into an eyelet (not shown). The assembly is locked on the dial by inserting a lug 3 in a slot in the dial and turning a loose tongue 30 until it engages over the lug 2. The latter movement is effected by a thin tool which is inserted past cut-away portions of the edges of the discs 4, 5 to engage the up-turned end of the tongue 30, and the same tool must be used to unlock the assembly. In a modification, the ring 1 has two opposite in-turned lugs which are entered into slots in the dial, the bends of the lugs riding into narrow circumferential extensions of the slots when the ring is turned. The disk 6 is formed with a radial spring tongue which at first rests on one of the lugs, but which cannot turn in the slot, so that when the ring is turned the tongue rides off the lug and springs down to lock it in the turned position. To turn the ring back, a tool must be used to lift the spring tongue. Specification 234,036 is referred to.

Abstract: 669,550. Follow-up systems. SPERRY CORPORATION. Feb. 26, 1948. [Aug. 19, 1943] No. 5810/48. Class 40 (i). A tracking device mounted on a ring 58 is actuated by a motor 84 to follow.a manually set sight 31, employing a misalignment signal at 366 opposed by a signal at 182 proportional to the speed of the motor 84 and opposed at 198 by a signal proportional to the rate of change of the torque of the motor 84. Relative phase displacements of windings 222, 362 are compared at 364 to produce a direct current primary signal at 366 proportional in sense and magnitude to misalignment of the tracking device. The signal at 366 is amplified at 128, 129, 131, 132 and applied to the field of a generator 82 driven at constant speed and supplying the armature 177 of the motor 84. A resistor 197 and.capacitor 199 are so arranged in parallel with a resistor 191 in the circuit of the armature 177 that the voltage across 197 produces a component proportional to the rate of change of torque of the motor 84. This component is added at 181 to a component proportional to the speed of the motor 84 and the resultant signal applied to 128, both components opposing the primary signal applied at 129. A voltage proportional to the torque of the motor 84 is introduced at 196 by a tapped resistor, and combined with the signal applied to 129 in a sense assisting the primary signal. The component produced at 197 avoids hunting at a frequency such that the signals applied at 128, 129 are 180 degrees out of phase.
