Title: Improvements in a signal transmitting repeater
IPC: H04M19/04
Filed: 1958-01-06
Abstract: 880,724. Automatic - exchange equipment. KALLSON, B. E. L. Jan. 6, 1958, No. 516/58. Class 40 (4). [Also in Group XL (b)] D.C. impulses of alternating polarity, such as are employed in telephone and telegraph circuits, are repeated from a line L1 to line L2 by an arrangement in which, in dependence upon the impulse polarity, one or the other of two A.C. channels A and B are rendered transmissive between an input transformer T1 and output transformers T2, T3, the outputs of the two channels being connected to line L2 over reversely-connected full wave rectifiers 1, 2 so as to produce D.C. impulses corresponding to the input impulses. It is stated that the arrangement may be employed to amplify the repeated D.C. impulses and also to correct their shape. The A.C. source supplying transformer T1 has a frequency considerably greater than that of the D.C. impulses. As illustrated, the switching arrangements for rendering the channels transmissive in dependence upon the impulse polarity comprise pairs of metal rectifiers V1, V2, of which those in one channel are connected in the opposite direction to those in the other. In a first modification, Fig. 2 (not shown), the channel windings on the input transformer are broken at the centres and joined through switching devices, such as thermionic valves, cold cathode valves or transistors. In a second similar modification, Fig. 3 (not shown), the broken centres are joined through networks of rectifiers and inductors. In third and fourth modifications, Figs. 4 and 5 (not shown), the switching arrangements comprise transistors. The input and output transformers are isolated by rectifiers, but have their centre-taps joined through the emitter-collector path of a transistor which receives the input D.C. impulses at the base. Transistors are also employed to couple the channel output rectifiers to the outgoing line.

Title: Improvements in or relating to treating continuous synthetic filamentary materials and continuous fabric sheet or web made thereof
IPC: B60C9/00
Filed: 1956-01-06
Abstract: Continuous heat-shrinkable synthetic filamentary material, or a continuous fabric, sheet or web made thereof, is treated by passing it through a zone in which it is stretched, e.g. 2-8%, at 320 DEG  to 450 DEG  F., and thereupon the tension on it is reduced sufficiently to allow it to shrink a controlled amount, e.g. 2-6%, at a lower temperature, preferably 150-180 DEG  F., whereby the length change characteristics of the material are reduced.  In an example, a continuous sheet of nylon fabric, after passage through a bath of a rubber-polyamide adhesion-promoting dip in which it is stretched 6%, is partially dried and then passed first through a zone at 400 DEG F. in which it is stretched a further 6% and then through a zone at 165 DEG  F. in which it is allowed to shrink 4%.  In the case of nylon the high temperature zone is preferably at 350-430 DEG  F., especially 400 DEG  F., and the shrinkage zone at 150-180 DEG  F., especially about 170 DEG  F.  The material may be polycaprolactam, polyethylene terephthalate or polyacrylonitrile.

Title: Improvements in or relating to photo-mechanical reproduction
IPC: G03F7/022
Filed: 1955-01-11
Abstract: <FORM:0772517/IV(b)/1> Quinoline - 3 : 4 - quinone - 3 - diazides of the formula shown are prepared by condensing anthranilic acid with nitro-acetaldoxime to give N - (b  - nitroethylidene) - anthranilic acid, ring-closing the latter with acetic anhydride to 3-nitro-4-hydroxy-quinoline, reducing the nitro group to amino catalytically or with sodium dithionite (isolating the amine as hydrochloride), diazotizing with sodium nitrite and treating the diazonium chloride with alkali.  The process is applicable to substituted derivatives (including those with condensed aromatic nuclei) and examples are given of the production of the following substituted quinone diazides and of the corresponding substituted intermediates: 7-methyl, 6 : 8-dimethoxy, 7-phenyl, 6-phenoxy, 6-chloro, 7-carbomethoxy, 6-sulphonic acid phenyl ester, 6-sulphon-n-butylamide, 6-sulphoncyclohexylamide, 6-sulphondimethylamide and 6 : 7-benzo.  7-Chloro-3 - amino - 4 - hydroxy - quinoline and 2 : 4-dihydroxy-3-amino-quinoline which can also be converted to the corresponding 3 : 4-quinone-3-diazides are made by nitration of 7-chloro-4-hydroxyquinoline and 2 : 4-dihydroxyquinoline respectively, reduction to amino and conversion to hydrochloride.  The following (substituted anthranilic acids) are made by reduction of the corresponding nitro compounds: 3-aminodiphenyl-4-carboxylic acid, 4-amino-diphenylether-3-carboxylic acid, 3-carboxysulphanilic acid phenyl ester, 3 - carboxy - N : N - dimethyl - sulphanilamide, 3 - carboxy - N - cyclohexyl - sulphanilamide and 3 - carboxy - N - butyl - sulphanilamide.  They are mostly isolated as hydrochlorides.  3 - Nitrodiphenyl - 4 - carboxylic acid is obtained by hydrolysis of its nitrile.  4 - Nitrile - diphenylether - 3 - carboxylic acid is prepared by condensing phenol with 2-nitro-5-chlorobenzoic acid.  4 - Nitro - 3 - carboxy - benzenesulphonyl chloride is made by diazotizing 2-nitro-5-aminobenzoic acid and passing in sulphur dioxide; this is reacted with phenol, dimethylamine, butylamine and cyclohexylamine to give the corresponding ester and amides.ALSO:Azo dyes are formed by coupling diazotized 3 - amino - 4 - hydroxyquinoline or its substitution derivatives with azo components; they form lakes with metallic salts.  Specified substituents are methyl, methoxy, phenyl, phenoxy, chloro, hydroxy, carbomethoxy, sulphonic acid phenyl esters and N - butyl, N - cyclohexyl and N:N - dimethyl - sulphonamide, and also condensed aromatic rings, e.g. 6:7-benzo.

Title: Improvements in and relating to web feeding devices
IPC: B65H23/038
Filed: 1962-01-10
Abstract: 968,370. Ink-ribbon mechanism. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 10, 1962 [Jan. 10, 1961], No. 927/62. Heading B6F. A carbon web feeding device in a printing mechanism having endless type belt 10, Fig. 1, movable along a print line, hammers 20 arranged along said print line and a carbon web 21, fed from a supply roll 22 to a winding roll 26, comprises a constant speed electrical motor 27 and associated gearing for advancing the carbon web in the said direction and a periodically operated detection device to cause a correction of misalignment due to the frictional contact of the web 21 with the moving types 11. A detecting lever 54, whose detection element 56 senses the misalignment of the carbon web from a home position and a restoring lever 40, carrying a roller 42 for restoring the misaligned carbon web back to said home position, the restoring lever 40 being operable in response to the detection of misalignment by the detection element 56, the detection and restoring levers being operable periodically in timed relationship with the advance of the carbon web. If during a printing operation the detection element 56 is placed on to a carbon web guide plate 25, Figs. 1 and 2, by the detection lever 54 upon actuation by a roller 70, fixed to a gear 29, and remains in a vertical position to indicate misalignment of the carbon web, then the restoring lever 40 will cause an interposer pawl 60 to be urged in an upward direction into contact with its leaf spring 62, biased by a pin 65 of the raised lever 54, to thereby enable a spring 46 to displace the restoring lever 40 and apply the restoring roller 42 to the surface of the carbon web 21. Since the axis of the restoring roller is skewed relative to the direction of motion of the carbon web, the frictional contact between the roller, carbon web and guide 25 results in an application to the carbon web of a lateral restoring force in opposition to the misaligning drag force. When during a further cycle the detection element 56 is placed on to the guide 25 and comes to rest on the surface of the carbon web, i.e. there is no misalignment, the advancing carbon web displaces the detection element 56 from a vertical to a horizontal position, Fig. 3, whereupon the detection lever 54 is lowered until its shaped upper portion engages a pin 41 and the pawl 60, during a subsequent displacement of the restoring lever 40, by the rotating roller 70, drops to engage with its detent 64 a stop edge 50 of the restoring lever 40 so as to prevent the roller 42 from being urged into frictional contact with the surface of the carbon web. Specification 919,653 is referred to.
