Title: Improvements in and relating to the production of artificial filaments, threads, fibres, bands and the like
Inventor: WORMELL ROBERT LOUIS
IPC: D01F1/10
Filed: 1952-06-13
Abstract: The process of the parent Specification for rendering freshly extruded protein filaments, threads, fibres, bands and the like resistant to the solvent and swelling action of cold and hot aqueous liquids, particularly hot dilute acids, is modified in that the esterification bath contains a phenol in addition to the methyl or ethyl alcohol and esterification catalyst.  The phenol may be mono-, di- or tri-hydric, and may be a substituted phenol. Phenol, ortho-, meta- or para-cresol or resorcinol may be used. The proportion of phenol in the esterification bath is preferably in the range of 0.1-5 per cent by weight.  In an example, a solution of milk casein in dilute caustic soda solution is extruded into a coagulating bath and the resulting threads, after a hardening treatment with formaldehyde, are stretched 400 per cent and hardened further by immersion in an aqueous bath containing formaldehyde and sodium sulphate at 50 DEG C. and at a pH of 3.5.  The threads are washed and then immersed in an esterification bath containing sulphuric acid, methyl alcohol, water and resorcinol.  The esterified threads are washed in water and treated with an aqueous hardening bath containing formaldehyde and sodium sulphate.  The threads are washed and then treated with a solution of sodium cyanate and subsequently dried. The resulting threads are very stable to boiling N/50 sulphuric acid.  In another example, fibres obtained by extrusion of a solution of milk casein are hardened with a solution of sodium sulphate, sulphuric acid, and formaldehyde.  The hardened fibres are esterified by treatment with a mixture of sulphuric acid, methyl alcohol, water and phenol.  The esterified fibres are washed and then soaked in a solution of sodium cyanate.  They are centrifuged to remove surplus liquor and then dried.  The fibres show a low imbibition of alkali, and are stable to boiling dilute acids.

Title: A device for signalling the failure of the rear electric lights of vehicles
IPC: B60Q11/00
Filed: 1951-06-26
Abstract: 711,361. Lamp failure alarms and warning- devices. FRIESS, W. June 26, 1951 [Dec. 14, 1950; March 31, 1951], No. 15149/51. Class 118 (2). A device for signalling the failure of rear lights of vehicles comprises at least one pair of relay windings in the current circuit of the individual lights having the same number of ampere turns wound in opposite directions on a common iron core, such that a switch disposed in the circuit of a signalling element is operated when the balance of the windings is disturbed by failure of a lamp. In the arrangement of Fig. 1, lamps 4 and 5 are supplied via winding 30 which has half the number of turns of winding 29 in the circuit of lamps 3 and that there is no resultant magnetisation of core 31. If one of the lamps 3, 4 or 5 fails the unbalance ampere turns cause closure of contacts 34, 32, and pilot lamp 33 is lit. A stop lamp 6 may be wired with a separate relay 35 and pilot lamp 37 as indicated in chain-dotted lines but a winding 38 acting on the core 31 is preferred. As shown the pilot lamp 33 is lit when the stop lamps 6 light. If one of the lamps 6 fails there are insufficient ampere turns on winding 38 to close contacts 34, 32 and failure of the pilot lamp 33 to light when braking indicates failure of a stop lamp. The same basic arrangement is used for vehicles having one or more trailers, as in Fig. 2. The rear lamps 3, 4, 5 of the motor vehicle are respectively in parallel with lamps 3', 4', 5<SP>1</SP> and 3", 4", 5" of two trailers and windings 30 and 29 are balanced so as not to light pilot lamp 33. But a winding such as 38 in Fig. 1, cannot be made sensitive to failure of one out of the six stop lamps, hence the stop lamps are supervised by a further pair of balanced windings 39 and 41. The winding 41 carries current of a resistor 42 and has tappings 44, 45, 46 selected according to the number of trailers in use. Alternatively the resistor 42 may be provided with tappings. To cause the pilot lamp 33 to light when the stop lamps light a back-contact 43 is provided normally connecting with contact 32; and to prevent the pilot lamp lighting when a stop lamp fails (causing closure of contacts 34, 32) a further relay 48 is connected to the stop lamp supply to contact 34 when the stop lamps are energised.

Filed: 1944-08-15
Abstract: 590,067. Multiplex pulse signalling. REID, D. G., and NOWACKI, P. J. Aug. 15. 1944, No. 15582. [Class 40 (v)] A multi-channel high frequency signalling system, uses characteristic groups of pulses for each channel, the time intervals between the groups being modulated by the signal, and each channel is identified by the fixed time interval or intervals between individual pulses of the group. As shown a microphone 2 modulates the time intervals between square pulses a produced by the generator 1 whose output is fed to a further generator 3 which may be of the type described in Specification 590,066 which converts each pulse into a group of three pulses b the time interval between which is fixed and characteristic of the channel. These pulses are fed to a radio transmitter 4. The transmitted R.F. pulses are demodulated by the receiver 5 whose output is fed to the coincidence amplifier system 6 set up to respond only to groups of pulses of the predetermined spacing. Thus the three positive pulses are fed to two grids of the first pentode V1, a delay network DN being interposed in the outer grid circuit to produce a delay equal to the pulse separation. When both grids are driven positive simultaneously anode current flows to produce an output pulse. In this way a group of three correctly timed positive input pulses. produces two negative output pulses. The polarity of the latter is reversed in transformer Tr and they are fed to a further similar circuit V1, DN, Tr which produces a single. pulse coinciding in timing with the third pulse of the group. The output c from circuit 6 is fed to an integrating circuit D1, C1, R1 which reproduces the original modulating wave d from microphone 2.
