Patent GB-420785-A (GB)
Title: Improvements in the manufacture of cuprammonium artificial silk
IPC: D01F2/04
Filed: 1934-04-16
Abstract: Cuprammonium artificial silk is made by the funnel spinning process using precipitating baths of extremely small precipitating power, the precipitating action of the bath and the diameter of the nozzle aperture being related such that a weaker precipitating action is compensated for by an enlargement of the nozzle aperture above a minimum of 1,5 mm.  For example, at withdrawal velocities exceeding 25 metres per minute and with baths, the precipitating action of which is less than that of softened water at temperatures exceeding 30 DEG  C., nozzle apertures exceeding 1,5 mm. in diameter are used. The precipitating action of the baths may be reduced by employing them at temperatures below 30 DEG  C., or by adding ammonia to softened water, or ammonia or acids to non-softened water.  For example, when using softened water at temperatures below 25 DEG  C., and withdrawal velocities of at least 30 metres per minute, nozzle openings of more than 3 mm. diameter are used.  In a modification, the precipitating action of the bath is decreased by circulating the liquid through the funnel, thereby increasing its ammonia content. In another modification, the quantity of liquid flowing through the funnel is decreased to below 600 c.cm. per minute and preferably below 300 c.cm. per minute.

Title: Depth sounder
IPC: G01S7/527
Filed: 1975-03-20
Abstract: 1509441 Echo sounders LAITRAM CORP 20 March 1975 [21 March 1974] 11635/75 Heading G1G A depth echo sounder has a receiver (14) Fig. 1 (not shown) and a processor (18) shown in Fig. 3, which processor discriminates between spurious and true bottom echoes, both echoes being above a predetermined level, and gives an indication of the depth. The processor 32-50 receives a train of pulses, Fig. 4A (not shown), from the receiver (14) each pulse corresponding to an echo, the width of the pulse depending on the duration of the echo above a predetermined threshold. An initial pulse from the slow clock 42 launches an acoustic pulse and resets down counter 44 and counter 34. If down counter is not at zero, gate 50 passes the modulated pulses representing the echoes. Each pulse passed by AND gate 50 transfers the count prevailing in counter 34 to memory 36 and down counter 44. The recycling through zero detector 46 and OR gate 48 provides a transient block to AND gate 50 as each zero is detected. This system prevents all spurious echoes and harmonics thereof from reaching memory 36. At the end of a pulse from clock 42, the updated number of counts stored is transferred to a digital display 63. The pulse width modulated pulses from the receiver (14) can be used directly to give an analogue depth display in which LED 62 is illuminated at an angle of rotation of disc 60 corresponding to depth.

Class 97(1) In a claw type intermittent film feed mechanism the claw carrying shuttle is reciprocated in the direction of feed by a three lobed constant diameter cam which is asymmetrical about a vertical axis when at top or bottom dead centre in such a way that the slope of the curve expressing claw displacement as a function of cam rotation is less at the point where the claw engages the edge of the sprocket hole than it would be if the cam were symmetrical. Thus the claw, the stroke of which slightly exceeds the perforation pitch is moving more slowly than it would be with a symmetrical cam when it strikes the edge of the perforation at the commencement of the feed stroke and noise is thereby reduced.

Title: Improvements in or relating to a method for insolubilising artificial filaments, threads, fibres and the like obtained by the spinning of solutions of proteins
Inventor: DAVIDSON WALTER LAMB
IPC: D01F4/00
Filed: 1953-04-28
Abstract: Insolubilized protein filaments, threads or like products are produced from a bundle of protein filaments which has been treated in succession with at least two hardening agents by impregnating the hardened filaments with an aqueous solution of formaldehyde of pH 0.5-1.5, drying the treated bundle below 100 DEG  C. and then heating it at 140-180 DEG  C. at least until the individual filaments are insolubilized.  The hardened filaments are preferably stretched, e.g. 200 per cent, after their impregnation with the formaldehyde solution and dried in the stretched condition.  The hardening treatment may comprise treating the coagulated and relaxed filaments with at least one solution of aluminium sulphate, polymeric sodium metaphosphate or sodium zirconyl sulphate, washing the filaments free from salts, and then treating them with a salt-free formaldehyde solution at a pH of about 3.5. The hardened filaments may then be further treated as described above, while still wet or after having been dried.  They may be dyed, e.g. with an aqueous solution of a dyestuff at 40 DEG C., before being treated with the formaldehyde solution of pH 0.5 to 1.5.  In an example filaments of coagulated peanut globulin produced in a described manner are treated for 5 minutes at 50 DEG  C. with a 10 per cent aqueous solution of aluminium sulphate brought to pH 3.3 with sodium hydroxide or borate, washed free from salts, further hardened by treatment for 3 minutes at 50 DEG  C. with 10 per cent formaldehyde solution at pH 3.5, and thereafter impregnated with a 10 per cent formaldehyde solution brought to pH 1 with hydrochloric acid.  The impregnated filaments are then stretched 200 per cent in air, mangled and thereafter thoroughly dried at 80 DEG  C. and heated for 30 minutes at 160 DEG  C. Specifications 513,910, 533,952, 593,928, 596,536, 597,497, 605,830, 623,460, 642,359 and 654,513 are referred to.
