Title: Production of artificial filaments by wet spinning
IPC: D01D5/06
Filed: 1960-12-01
Abstract: 975,171. Wet spinning artificial filaments. CELANESE CORPORATION OF AMERICA. Dec. 1, 1960 [Dec. 11, 1959], No. 41291/60. Drawings to Specification. Heading B5B. In the production of filaments by spinning a solution of a filament-forming material into a liquid coagulant exerting a swelling effect on the material filament formation is initiated by extruding the spinning solution into a liquid, hereinafter called a precipitant, which coagulates the extruded solution but exerts a lower swelling action on the filament-forming material than does the coagulant, and withdrawing filaments from the spinneret face at a speed low enough to avoid filament breakage by conducting them along the path they are to follow during spinning into operative relationship with take-up means for the filaments and thereafter by replacing the precipitant by the coagulant while continuing extrusion and increasing the speed at which the filaments are withdrawn to a speed giving a predetermined draw-down ratio when the spinneret is surrounded by coagulant. The precipitant may consist wholly of a non- solvent for the filament-forming material and the coagulant may consist of a mixture of the non-solvent with a solvent for the filamentforming material. Alternatively, the precipitant and coagulant may consist of mixtures of the same ingredients in different proportions, e.g. mixtures of a solvent and a non-solvent for the filament-forming material or a mixture of non- solvents of unequal swelling effect on the filament-forming material, the coagulant containing a higher proportion than the precipitant of the solvent or of the non-solvent of higher swelling effect. When spinning into the precipitant the draw-down ratio is maintained at or below 1 and the draw-down ratio is not increased to above 2 until the spinneret is surrounded with coagulant of the desired composition, and preferably increase above 2 does not take place until the coagulant extends at least 2 inches beyond the spinneret face in the direction of filament travel. The draw-down ratio may then be increased considerably, for instance in the case of cellulose triacetate it is preferably increased to above 5. Preferably, the method disclosed in Specification 975,172 is used to prevent the spinneret orifices being blocked by solid filament-forming material by coagulation of the spinning solution in the orifices. The present process may be used in combination with the process described in Specification 826,098 using a spinning solution the solvent of which comprises at least 85% of a halogenated alkane such as methylene chloride and up to 15% of one or more alkanols containing 1 to 3 carbon atoms in the molecule. The present process may be applied to the wetspinning of solutions of the acetate, propionate, butyrate, acetate-formate, acetate-propionate and acetate-butyrate of cellulose, and particularly solutions of cellulose triacetate.

Title: Improvements in or relating to apparatus for causing repetition of incorrectly received messages in electrical digital signalling systems.
Inventor: THOMAS DAVID LLEWELYN
IPC: H04L1/18
Filed: 1968-08-30
Abstract: 1,224,388. Digital transmission systems. PLESSEY TELECOMMUNICATIONS RESEARCH Ltd. 20 Aug., 1969 [30 Aug., 1968], No. 41614/68. Heading H4P. In a synchronous electrical signalling system means are provided for causing repetition of incorrectly received messages, comprising at the transmitter a counter allotting numbers to successive messages and a store for storing a number of the most recently transmitted messages together with their allotted numbers. The receiver determines whether any received message contains an error and sends an error message to the transmitter when an error is detected, the error message including the number of the message containing an error. The transmitter extracts from the store the message corresponding to the number in the error message and retransmits it. No acknowledgement is sent of a correctly received message. Data to be transmitted is applied at 10 to queueing unit 12 which stores a queue of messages to be transmitted. The message counter 14 reads out the stored messages in turn, generating a number for each. If the store is empty, the counter transmits an idle message consisting of the next message number. The message to be transmitted is passed to a parity digit insertion unit 16 and to a sent message file 18. The unit 16 inserts a digit to give the message the required parity and the message is then transmitted. Incoming signals are applied to a parity check unit 30. If no message is received at the time one is expected, this is treated as an error. The checking unit 30 determines whether a received message is a data message, an idle message, or an error message. Data messages pass to output store 32. An idle message passes to message counter 34 so that the number in the idle message can be compared with that indicated by counter 34. Corrections are made if the numbers differ. If the parity checker detects error or if no message is received when one is expected, a signal is sent to an error message compiler 35 which produces an error message including the message number indicated by counter 34 and inserts it in the queueing unit 12. If an error message having the correct parity is detected by unit 30 a signal is passed to error message control 36 which passes the number of the erroneously received message to the sent message file 18 causing the corresponding message to be re-inserted into the unit 12 for retransmission. Unit 12 has three queues, a first for original data messages, a second for messages to be retransmitted following receipt of an error message, and a third for error messages. The third queue has the highest priority and the first queue the lowest. If there is a number of receivers, receiving messages from a single transmitter, any one receiver may send an error message, such message including the identity of the receiver. The transmitter then retransmits the required message only if it is relevant to that receiver.
