Patent GB-1279374-A (GB)
Title: Data transmission apparatus
Inventor: TANG DONALD TAO-NAN
IPC: H04L25/49
Filed: 1971-04-19
Abstract: 1279374 Digital transmission systems; coding and decoding INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [24 Feb 1970] 21087/71 Heading H4P In a system for increasing transmission speed, binary sequences are recoded into other sequences whereby similar digits e.g. two l's cannot occur adjacently, the other sequences being transmitted over a raised cosine type of channel. As each transition is clearly identifiable, it is stated that transmission may be at a greater rate e.g. double speed than systems where two or more 1's are adjacent, also due to one bit period being interposed between each transition, the system has time to settle down during this period. A further advantage stated is that synchronization may be effected by sampling wave damped-oscillations at half bit periods (see Fig. 3, not shown). In the embodiment described five bit sequences are recoded into 7+1 bit sequences, those sequences with adjacent 1's not being used and the + 1 digit being a buffing digit between the sequences. Such sequences may be transmitted by a NRZI code i.e. where a transition from + 1 to -1 or conversely is a "1" and no transition is a "0". Sequences of 7 +1 digits may be transmitted during the same time period as a normal four digit code and further economy may be effected by selecting an optimum coding scheme. The recoding may allow any integral number of 0's between 1 and K: k may be limited to a determined integer or may equal infinity. It is stated that the arrangement enables either a d-limited (k = infinity) or dk limited (k is finite) transmission without interference at a rate of four times the skew symmetry frequency (twice cut off frequency) of a similar system employing codes with adjacent 1's. Coding and decoding arrangements are described in connection with Figs. 11 and 12 (not shown). The coder illustrated in Fig. 11 may be adapted from the general purpose dk-limited coder disclosed in Specification 1,239,113.

Title: Process for permanently setting or for presensitising fabrics containing keratin fibres
IPC: C07F9/24
Filed: 1964-05-26
Abstract: In a process for permently setting fabrics containing keratin fibres in a desired configuration, e.g. creased, pleated or flat configuration, or for presensitising such fabrics by imparting a propensity for permanent setting thereto, including the steps of contacting the fibres with a reducing agent and heating, the characteristic odour of reducing agent treated fibres is substantially reduced or eliminated in the permanently set fabric formed, or which can be formed by setting the presensitised fabric, by contacting the fibres before or after making into the fabric with the reducing agent in the presence of an aldehyde-generating compound which will release an aldehyde at the elevated temperatures required to set the fabric.  Suitable aldehyde generating compounds are paraformaldehyde, polyoxymethylenes, formals, methylol alkanolamine sulphites, methylol amides, hexamethylene tetramine, trimethylolmelamine and alkali metal formaldehyde disulphites. Suitable reducing agents are zinc or sodium formaldehyde sulphoxylate, sodium or potassium borohydride, bisulphite, sulphite, metabisulphite or hydrosulphite, thioglycollic acid, sodium, potassium or ammonium thioglycollate, hydrogen sulphide, sodium or potassium hydrosulphide, butyl or ethyl mercaptan, b -mercapto-ethanol, ammonium bisulphite, sodium sulphide, cysteine hydrochloride, sodium hypophosphite, thiosulphate or dithionate, titanous chloride, sulphurous acid or mixtures thereof.  In the production of presensitised fabrics the fabric may be treated with the reducing agent and dried and subsequently made into garments and/or arranged in a desired configuration if necessary after spraying with water and then heated.  If the presensitised fabric is not sprayed with water prior to heat setting the reducing agent solution may contain a polyhydroxy compound having a molecular weight no greater than 4,000 or a swelling agent, e.g. urea, guanidine hydrochloride, formamide, N,N-dimethyl formamide, acetamide, thiourea, phenol or lithium chloride, bromide or iodide.  The presensitisation process may also comprise treating the fabrics with a reducing agent precurser, e.g. an alkanolamine or other amine, alkali and alkaline earth metal hydroxides, carbonates, borates or phosphates, aldehydes and ammonia, finishing by conventional mill finishing operations, e.g. semidecatising, and then exposing them to a gaseous reducing agent activator, e.g. SO2, hydrogen sulphide, methyl or ethyl mercaptan, 2-mercaptoethanol, nitrogen oxides, phosphine, NOCl and NOBr.  Fabrics comprising wool alone or in admixture with other keratinous fibres, e.g. mohair, alpaca, cashmere, vicuna, guanaco, camels hair and llama, or synthetic fibres, e.g. polyamide, polyester or acrylic fibres, may be treated.
