Patent GB-956401-A (GB)
Title: Process for the dyeing and printing of polyester fibres
IPC: D06P3/02
Filed: 1961-08-22
Abstract: Aromatic polyester fibres are dyed or printed by applying an aqueous composition containing a dispersion of a water-insoluble dyestuff, advantageously a thickener and an assistant which is capable of forming with water or with water and an additive, a system consisting of two liquid phases having a miscibility gap, the proportional amounts of water which may contain additives on the one hand and the assistant on the other hand being within the miscibility gap, with the miscibility gap occurring even at a relatively low content of assistant and the phase richer in assistant making up a substantial part within a large range of the miscibility gap, the fibres so treated are then steamed.  The fibres may be of polyethylene terephthalate, if desired, blended with other non-nitrogenous fibres such as cotton.  Particularly suitable dyes are vattable dyes of the indigo and anthraquinone series.  Direct dyes may be included when dyeing polyester/cotton blends.  Especially suitable assistants are hydrophilic colloids which are capable of coacervation.  The aqueous composition is advantageously in the form of a homogenized two-phase system which may be stabilized with a thickener, preferably sodium alginate.  The specified assistants are the reaction products of higher fatty acids with hydroxy-alkalamines and, if desired, ethylene oxide, in the ratio of 1-2 mols amine to 1 mol fatty acid to 1-15 mols ethylene oxide if required, especially from coconut oil fatty acid and tri- or di-ethanolamine or dihydroxyethylethylenediamine, as well as adducts of ethylene oxide or a polyethylene glycol with higher fatty acids, higher aliphatic alcohols, alkylphenols, higher alkylmercaptans and higher aliphatic amines.  The formation of a two-phase system may be promoted by the addition of, e.g. acetic acid and/or sodium chloride.  The compositions may be applied at temperatures up to 80 DEG C in any known way, especially continuously, e.g. by padding, roller, screen or Vigoreux printing. Fixation is achieved by steaming, preferably at 130-140 DEG C., and may be followed by rinsing in a bath at 70-80 DEG C. containing a detergent and, in the case where a vattable dye is used, sodium hydrosulphite.  Examples of the dyeing and printing of polyester fabrics and slubbings are given.

Title: Paging terminal system
IPC: H04Q11/04
Filed: 1974-07-09
Abstract: 1450971 Automatic exchange systems MOTOROLA Inc 9 July 1974 [19 Sept 1973] 30412/74 Heading H4K A paging system comprises a number of remote concentrators which each concentrate paging requests for a plurality of trunk lines on to a single line extending to a central paging terminal. The central terminal, subsequent to the receipt of a request, seizes a line extending to an appropriate remote concentrator to cause a transmitter thereat to transmit a R.F. paging signal, 16 paging trunks 1-16 emanating from telephone exchanges, answering services &c. are connected to each remote concentrator 20, 25, 26, 27 the concentrators comprising for each trunk a data set and a supervisor and register circuit. In operation the supervisor and register circuit detects an incoming call on the associated trunk and answers the request by first looping the trunk, and then by sending a tone to the caller to request the identity of the person to be paged. The caller responds by transmitting the identity in tone form to the data set where it is converted to binary code before being stored in the register section of the supervisor and register unit. In each remote concentrator a scanner unit comprising a plurality of bistable circuits and counter circuitry (Fig. 3, not shown) sequentially scans the register sections for information to be conveyed to the central terminal, and causes any stored information to be read out over the line 23, 28-30 extending thereto. The central terminal checks the validity of the received identity and if it is invalid the remote concentrator is caused to repeat the transmission thereof. Should the identity fail the validity test a second time the remote concentrator is caused to send an invalid identity tone to the caller. At the end of each sequential scan of the registers the control terminal can delay the start of the next scan and seize the lines to the concentrators to gain access to the transmitters. All the paging requests received and stored at the central terminal during the previous scan/s are then fed to appropriate transmitters for broadcast. Paging units of the well known "bleeper" type are thereby caused to operate and the paged person reponds by dialling the number of his answering service &c.
