Title: Process for improving the appearance and dyeing properties of synthetic linear condensation products
Inventor: DUBEAU ARCHIE L
IPC: D06P1/673
Filed: 1940-05-06
Abstract: 539,566. Resinous condensation &c. products ; dyeing and bleaching; artificial filaments, films &c. MATHIESON ALKALI WORKS. May 6, 1940, No. 8145. Convention date, June 23, 1939. [Classes 2 (ii), 2 (iii) and 15 (ii)]' A solid resinous body composed of a synthetic linear condensation polymer capable of being- drawn into fibres with longitudinal orientation of the micelles, is subjected to treatment with an aqueous solution containing chlorite ions so as to remove discoloration and to increase its ability for being dyed. The polymer may be a polyamide obtained from a diamine and a dibasic acid or an amide-forming derivative of such acid, a polyamide obtained from an amino acid such as 5-amino caproic acid, a polymerization product of hexadecamethylenedicarboxylic acid and trimethylene glycol, a polyanhydride derived from a dibasic acid such as adipic or pimelic acid, or a polyesterproduced from a dibasic acid in presence of a diamine. A polyamide obtained from hexamethylene diamine and diphenic, adipic, or sebacic acid may be used. The polymer may be in the form of filaments, fabrics, bristles, sheets, ribbons, rods, tubes, or other shaped article. The treatment enables dyestuffs to penetrate the polymer more uniformly and to give a brighter and more uniform finish. Thechlorite solution is preferably used in acidcondition since under this condition the strength of the article treated is not appreciably reduced and in many cases is increased. If the chlorite solution is used in alkaline condition it is preferable to have hypochlorite ions present also. Bleaching is facilitated by including in the acid chlorite solution a small proportion of a synthetic detergent such as sodium lauryl sulphate, sodium 2-methyl pentane-4-sulphate, sodium sulphoethyl methyl lauramide, sodium sulphoethyl myristate, sodium diamyl sulphosuccinate, sodium decyl benzene sulphonate, and sodium hexadecyl sulphonate. The chlorite solution may be obtained by dissolving sodium chlorite in water, diluting to the required strength and adding acid or alkali to give the required pH value. Acetic acid, mineral acids, or alkali metal hydroxide, may be used. The treatment may be effected under acid conditions at elevated temperature. The use of a syntheticdetergent tends to bring about an increase in the tensile strength. If desired the materials may be subjected to treatment with an alkaline aqueous solution of sodium hypochlorite and then, without washing, to a treatment with sodium chlorite solution.

Title: Improvements in electric facsimile communication systems
IPC: H04N1/44
Filed: 1944-05-03
Abstract: 685,989. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). May 3, 1944, No. 8398/44. Class 40 (v). An electric facsimile communication system comprises means for transmitting a train of jamming pulses spaced apart at predetermined intervals, means for transmitting facsimile signals during certain selected ones only of the said intervals, and means for transmitting during one of said intervals a preparatory signal which conditions the receiver to respond to the facsimile signals. In the form shown in Figs. 1 and 2, a transmitting station 10 includes a generator 12 for producing jamming synchronizing pulses 38 which are radiated from a transmitter 16 on a first frequency, and a facsimile waveform generator 18 which is synchronized by generator 12 and which produces a facsimile waveform 40 which is radiated on a second frequency, in the gaps between jamming pulses, from a second transmitter 26. At the receiving station 24, a receiver 34 tuned to the pulse wavelength feeds a pulse detector 36 to obtain pulses used to synchronize the reproducer stage 32 of a receiver 26 tuned to the frequency of the facsimile signal. If desired. further confusion is caused by radiating random jamming pulses 42 between the synchronous jamming pulses 38 in the absence of a facsimile signal. To economise power, the reproducer 32 may be triggered into operation by a signal 41 which precedes the facsimile signal. In a modification, Fig. 4 (not shown), the jamming pulses are radiated on the same frequency as the facsimile signal. Fig. 6 shows a system in which a transmitter 64 and receiver 66 may operate in enemy territory under the supervision of a transmitter 62 in friendly territory. Transmitter 62 radiates synchronizing and random jamming pulses only. The synchronizing pulses are detected at 36 in station 64 and used to synchronize a facsimile waveform generator 18<SP>1</SP>, which radiates from transmitter 22. Receiver 66 is the same as 24 in Fig. 1 but receives its facsimile signal from station 64 and its synchronizing pulses from 62. This makes stations 64, 66 difficult to locate.

Title: Test arrangement
IPC: G06F11/273
Filed: 1975-02-28
Abstract: 1467122 Testing electrical apparatus WESTINGHOUSE ELECTRIC CORP 28 Feb 1975 [8 March 1974] 8432/75 Heading G1U An apparatus comprising a number of individual units is tested by including in each unit a test module which can be individually selected from a central console to carry out operational tests on the corresponding units, the operational status of the unit being determined by comparison to expected test results, and a signal representing the status being gated to the console by the module on receipt of an interrogate signal. Each module contains interface circuitry 26 including stores, whose outputs pass to multi-plexers 33 ... 34, which combine the signals from the unit being tested into a number of groups of eight signals each, representing various tests. Each multi-plexer has a unique address, selected by an address counter 31. The multi-plexer outputs pass to a comparator 35 where they are compared with an eight-bit word derived from a memory 32, the word also being selected by the address counter 31 and representing the expected results. The comparator output passes to a shift register 36. On receipt of a signal from the central console over address line 20, decoder 25 examines it and if it relates to the particular module, passes a signal to clock 30 and to interface circuitry 26 which performs the required test schedule. When the output stores are ready, a "start test" signal is fed back to clock 30 which then produces a group of pulses sufficient to step the address counter 31 through all its stages. Each multi-plexer is energized in turn, the test results being compared with the corresponding memory word and feeding the status result to the register 36. Thus at the end of the test, register 36 contains all the results, the presence of any zeros indicating a faulty unit. A "results available" signal is now released over line 21, followed by the status indication. The whole system has two modes of operation. In the first, the operator selects a unit to be tested, and the module on receipt of the corresponding code performs the steps outlined above. In the second mode, each module continually tests its unit, and on receipt of an interrogate signal stops testing to transmit the last available status result. The signals transmitted by the central console are three-level signals, the negative portions defining a synchronizing clockpulse train and the positive portions forming the code signals.
