Title: Improvements in or relating to electric telegraph receiving systems
IPC: H04L15/26
Filed: 1935-01-11
Abstract: 436,423. Selectors responsive to code signals. WATANABE, Y., 7, 4-chome, Kinukake-cho, Suma-ku, Kobe, Japan. Jan. 11, 1935, No. 1082. Convention date, March 12, 1934. Addition to 436,343. [Class 40 (iv)] A selector in which, as described in the parent Specification, a received Morse signal is registered by the transverse displacement of rollers 4 carried by the bars 3 of a squirrel-cage construction, the rollers controlling spring contacts so that when a particular signal is received an alarm circuit is completed, is modified to enable it to complete characteristic alarm circuits in response to several different signals. The controlling circuits and the constructional arrangements are the same as in the parent Specification except that the rollers control multiple spring sets as shown in Fig. 3, instead of simple pairs of springs. As shown in Fig. 7, each of the predetermined signals causes the operation of one of the relays q1 ... q5 which locks up and gives an individual lamp signal. In addition there is a buzzer Z1 common to four of the lamps and a further buzzer Z individual to the fifth. Each of the relays q1 ... q5 opens a point in a chain circuit in the input circuit of the relay R that repeats the telegraph signals so that, unless key K2 is operated to shunt this chain circuit, operation of relay R is ineffective after any of the alarm circuits has been completed. Normal conditions are restored by key K3 which unlocks the operated relay q1 ... q5 and sends an impulse to step the selector mechanism on and so break the initial circuit of the relay q1 ... q5.

Title: Improvements relating to tracking mechanism for automatic musical instruments
IPC: G10F5/06
Filed: 1919-01-17
Abstract: 139,257. Aeolian Co., and Nicholson, E. G. Jan. 17, 1919. Tracker-bars; winding- mechanism.-A trackerbar is provided with pairs of narrow control ducts c, c<1> which are both exposed by the sheet-perforations when the latter are in correct register with the noteducts b; the exposure of only one duct of each pair actuates a pneumatic device which moves the tracker-bar in guides r so as to restore correct registration. The left-hand ducts c are connected by flexible tubes d with a passage e, and the right-hand ducts c' by tubes d<1> with a passage e<1> in a bar f. Exposure of the left-hand ducts causes atmospheric pressure to be communicated through tubes h, m to the underside of a diaphragm l in a valve-box k, raising a valve k<1>, so that a pipe o<1> normally in connexion with an exhaust pipe k<3> is connected to the atmosphere. Similarly, exposure of the right-hand ducts c<1> admits air to the pipe o<2>. The pipes o<1>, o<2> are connected to separate bellows chambers n<1>, n<2> having a common fixed partition n and their free sides connected by a bar n<3>, so that these move to the right or left according as one or the other chamber is inflated, but remain in a central position when both are inflated. The right-hand wall is connected by a rod n<4> and a lever (not shown) so as to move the tracker-bar in the direction required to expose both control ducts. On rewinding a sheet, a chamber g normally connected to exhaust is connected to atmosphere, causing diaphragms i to cut off the connexion between the pipes h, h' and the controlling-device. In a modification, the passages e, e' are formed in the tracker-bar itself.

Title: A process for the preparation of polyvinyl chloride
IPC: C08F114/06
Filed: 1957-01-15
Abstract: Vinyl chloride polymers are made by polymerizing vinyl chloride alone or in admixture with another ethylenically unsaturated monomer in aqueous emulsion at a pH of 8.5 to 11 in the presence of hydrogen peroxide and an emulsifier which is a monocarboxylic acid salt with 8 to 22 carbon atoms in the molecule and after-treating the vinyl chloride polymer with a water-ionizable metal compound to convert residual emulsifier present in the polymer to a water-insoluble or substantially water-insoluble compound.  The process is preferably effected continuously by addition of the polymerizable ingredients and removal of the reaction products.  The water-ionizable compound is generally a salt of a metal of Group II of the Periodic Table or lead.  Suitable salts are the formates and acetates of calcium, lead, barium, and cadmium.  The emulsifier may be ammonium laurate.  The other monomer may be vinylidene chloride, vinyl acetate, or an acrylic or methacrylic acid ester.  The treatment of the vinyl chloride polymer may be carried out by utilizing the water-ionizable salt as a coagulant, or by coagulating the latex with formic acid and treating the coagulate with the water-ionizable salt, or the latex may be spray-dried and then treated with the salt.  The coagulate may be heat-treated at temperature between 80 DEG  and 160 DEG  C. at any stage in the after-treatment.  The polymers are used in electrical insulation.

IPC: C07C215/16
Filed: 1948-01-19
Abstract: Amino alcohols of the general formula <FORM:0689162/IV (b)/1> are prepared by condensing ketones of the general formula <FORM:0689162/IV (b)/2> where R1 and R2 are non-aromatic radicals which may together form an alicyclic ring and in which Ar is any aromatic radical, with primary aromatic amines and then reducing by catalytic hydrogenation the anils so formed.  The hydrogen atom attached to the nitrogen atom may be replaced by an alkyl group by usual alkylation method.  The preferred method is to heat with an aldehyde or ketone in the presence of a boiling solvent which forms an azeotropic mixture with water to form a compound of the formula <FORM:0689162/IV (b)/3> where R1 and R2 are as above and R4 and R5 are one or both hydrocarbon radicals, the other may be hydrogen which on catalytic hydrogenation gives <FORM:0689162/IV (b)/4> Examples for R1, R2 and <FORM:0689162/IV (b)/5> are butyl, isobutyl, tert.-butyl, 2-ethyl-hexyl dodecyl, benzyl, b -phenylethyl, g -phenylpropyl, cyclopentyl, cyclohexyl, d  - chlorobutyl, e  - bromopentyl, b -hydroxyethyl, a -hydroxy-isopropyl, e -diethylamino-pentyl, and examples of Ar are phenyl, o-, m-, and p-tolyl, 2-methoxy-5-methyl-phenyl-, p-chlorophenyl, m-ethoxyphenyl, a -naphthyl and b -naphthyl. Compounds in which R1 and R2 together form an alicyclic ring can be made by the interaction of acetylene with cyclohexanone and cyclopentanone and subsequent dehydration.  In examples: (1) methyl-butanolone and aniline were refluxed to form 3-methyl-3 butanol-2-one-anil which was hydrogenated catalytically to form 2-anilino-3-methyl-3-butanol; (2) as in example (1) but using o-methyl aniline to form 2-(o-methylanilino)-3-methyl-3-butanol; (3) as above, using o-methoxyaniline; (4) as above, using p-methoxyaniline; (5) as above using o-chloraniline.  Compounds of the formul  <FORM:0689162/IV (b)/6> can be synthesized by the interaction of acetylene with cyclohexanone and cyclopentanone and subsequent hydration. Specifications 313,617, [Class 2 (iii)], and 646,951 are referred to.ALSO:Amino-alcohols of formula <FORM:0689162/IV (c)/1> where Ar is aryl, R1, R2 and R3 are non-aromatic radicals, R1 and R2 are either separate radicals or together form an alicyclic ring and R3 may also be hydrogen, are coupled with unspecified diazonium compounds for dyeing nylon, cellulose esters and plastic materials.

Abstract: 978,427. Spin driers. HOOVER Ltd. Jan. 16, 1961 [Jan. 19, 1960], No. 1993/60. Heading F4G. [Also in Division D1] A spin drier comprises a basket mounted to rotate in a stationary container which is resiliently suspended from a frame or support and which has a pair of pivot points on opposite sides of the container and together having a common axis extending through or adjacent a diameter of the basket, and a linkage system connecting each pivot point to the frame and arranged to prevent bodily movement of the basket along its axis in at least one direction, the linkage system including a pair of links extending generally parallel to the basket axis and a differential device extending between corresponding ends of the links, which device is arranged to permit one pivot point to move in one direction as the other moves in the opposite direction substantially parallel to the normal position of the axis of the basket. A spin drier comprises a basket 13, Fig. 1, mounted to rotate about an axis inclined at 30 degrees to the horizontal within a stationary container 12 which is supported from a frame 11 by tension springs 38, 44 and a differential tension wire 50. A spring 38 is secured to each side of the container at a point 39 on a horizontal line extending slightly above and to the rear of the centre of gravity of the container and a spring 44 is mounted on each side of the container adjacent its mouth above its axis to produce a force on it it counteracting the tendency of the container to tilt about the points 39 so that the springs 38, 44 together produce a resultant force approximately at right angles to the inclined axis of the container in a vertical plane containing the axis. The wire 50 is secured at each end adjacent the points 39 and extends thence substantially parallel to the axis of the container in a upward and forward direction over a pulley 51, 52 adjacent the front of the drier so as to form link portions 56 and from the pulleys 51, 52 descends around pulleys 53, 54 in order that the central portion 57 of the wire is taken clear of the coaxial open forward loading ends 14, 15 of the basket and container. The differential suspension system enables the suspended parts to vibrate in a direction transverse to the inclined axis of the basket, but vibration parallel to the axis is substantially prevented. A heavy annular counterweight 58 is mounted about the opening 15 of the container to move the centre of gravity of the suspended parts towards the geometric centre of the basket. A rubber gasket having a corrugation is mounted between the opening 15 of the container and an aligned opening of an outer casing both to prevent liquid spilling between the container and casing and also to enable the basket and container to vibrate transversely to its axis relatively to the casing when an eccentric clothes load is being spin dried. The tension wire 50 may be replaced by a system of struts or gimbal rings. Specification 972,278 is referred to.
