Title: Process for finishing keratinous fibre fabrics
IPC: D06M11/05
Filed: 1964-05-26
Abstract: Lustre is imparted to a keratinous fibre containing fabric by treating the fabric with a reducing agent capable of splitting the cystine disulphide linkages in the keratinous fibres, paper pressing under conditions insufficient permanently to set any significant portion of the reducing agent treated keratinous fibres of the fabric and then fully-decatising the fabrics.  The reducing agent may be an alkanolamine sulphite containing up to 8 carbon atoms in the alkyl chain, zinc or sodium formaldehyde sulphoxylate, sodium borohydride, potassium borohydride, sodium potassium borohydride, sodium or potassium bisulphite, sulphite, meta bisulphite or hydrosulphide, ammonium bisulphite, sodium sulphide, hypophosphite, thiosulphate or dithionate, titanous chloride, sulphurous acid, thioglycollic acid and its water-soluble salts, hydrogen sulphide, ethyl or butyl mercaptan, b -mercapto ethanol or mixtures thereof.  The reducing agent may be applied to the fabric as an aqueous solution containing 0.01-20% by weight of the reducing agent by spraying, padding, squeezing, immersion or wetting with blankets saturated with the solution.  The fabric may then be rolled and stored or partially air dried and stored prior to paper pressing.  Prior to paper pressing the fabric may be subjected to mild semi-decatising with 5 seconds of steaming and 2 minutes of vacuum.  Paper pressing may be carried out at pressures of 50-1000 p.s.i. at temperatures of 70 DEG -200 DEG F for 6-8 hours, the pressing time interval being repeated after shift of the fabric.  The fabric is then subjected to full-decatising preferably with a steam interval of 1-10 minutes at a pressure of 1-100 p.s.i. and a vacuum interval of 2-60 minutes.  The treating solution may also contain a swelling agent, e.g. urea, guanidine hydrochloride, formamide, N,N-dimethyl formamide, acetamide, thiourea, phenol or lithium chloride, bromide or iodide, or a polyhydroxy compound containing more than one hydroxy group and having a molecular weight no greater than 4000, e.g. ethylene glycol, trimethylene glycol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, decamethyene glycol, 1, 2-propylene glycol, dipropylene glycol, 1, 3-butylene glycol, diethylene glycol, polyethylene glycol, polypropylene gycol, glycerine, diethyl glycerol, trimethylol ethane, trimethylol butane or triohydroxymethyl amino methane.  Fabrics comprising keratinous fibres, e.g. sheep wool, lamb wool, mohair, alpaca, camel hair, cashmere, vicuna, llama or angora wool, alone or in admixture with other fibres, e.g. polyester fibres, may be treated.

Title: Improvements in or relating to data transmission systems
Inventor: COTTON JOHN MICHAEL
IPC: H04L12/42
Filed: 1966-05-17
Abstract: 1,168,476. Digital transmission systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 15 May, 1967 [17 May, 1966], No. 21829/66. Heading H4P. In a digital transmission system in which a plurality of stations are connected to a common line which is in the form of a ring circuit each station has a different priority. If two stations simultaneously wish to transmit their priorities are compared and the station of higher priority is allowed to transmit. A signal can be transmitted only when the preceding signal has passed completely round the ring and agrees with the originally transmitted signal. The ring consists of ten data wires for parallel-bit signals and of four control wires which are selectively energized to indicate, for example, whether the ring is free or busy and whether a called station is free or busy. If station A wishes to transmit and if the ring is not busy it breaks the ring and sends its priority number. At B, if B does not wish to transmit, the number is passed on to C. If B also wishes to transmit, the priorities of A and B are compared. If that of A is greater, transmission from B is suppressed and A's priority number passes on to C. However, if B's priority is greater B's priority number is sent on instead of A's, and the continuity of the line at A is restored. If no station, other than A, wishes to transmit, A's priority eventually returns to A, having completed the ring. Station A now seizes the ring by energizing one of the control wires and transmits the address of the required station. At B the called address is compared with B's address and if it is not the same the called address passes on to C. If it is the same, i.e. A wishes to communicate with B, then if B is busy B is made to take up a waiting condition after it ceases to be busy so that A can make another attempt to establish communication, which it does after a preset time. If B is free the address eventually returns to the transmitter which then transmits a data signal to the selected receiver. The signal passes round the ring to station A where it is compared with the received signal. If it is the same, the next signal is sent. If not, an error signal (all ones) is transmitted to inform the receiver of the fault. Should the receiver detect a fault a repetition requesting signal is returned to A. The end of message code is an all zero signal. Two or more ring circuits are provided. These may be used sequentially. If the error rate becomes too high the presently used ring is replaced by another. A station may transmit data to more than one other station.
