Title: Improvements in or relating to the treatment of cellulose acetate products
IPC: D06P5/22
Filed: 1921-11-02
Abstract: The partial alkaline saponification of cellulose acetate threads, films, or fabrics, to facilitate drying, is effected by means of substantially cold solutions of caustic alkali of 2 to 15 per cent strength, the reaction being retarded and controlled by cooling to low temperatures (below 0 DEG  C.), or by adding alkali metal salts to the solution, or by coating the goods with an insoluble film of soap.  The material may be impregnated with the solution and then drained, squeezed, or whizzed so as to leave on the material only sufficient alkali for the required saponification, or the material may be left in the solution until sufficiently saponified and then removed and washed or neutralized.  Mixed goods containing cellulose acetate and cellulose threads may be treated by the process. Specification 20672/10 is referred to.ALSO:The partial alkaline saponification of cellulose acetate threads, films or fabrics, to facilitate dyeing, is effected by means of substantially cold solutions of caustic alkali of 2 to 15 per cent strength, the reaction being retarded and controlled by cooling to low temperatures (below 0 DEG  C.), or by adding alkali metal salts to the solution, or by coating the goods with an insoluble film of soap.

Title: Improvements in or relating to apparatus for testing control or other signal responsive systems
IPC: H04R29/00
Filed: 1962-07-30
Abstract: 985, 490. Impedance measurement; testing servo systems. WAYNE KERR LABORATORIES Ltd., and G. G. GOURIET. July 10, 1963 [July 30, 1962], No. 29246/62. Heading G1U. [Also in Division H3] Apparatus for testing a control or other signal responsive system comprises a random signal generator of adjustable bandwidth, a comparator for comparing the root mean square values of two input signals, means for applying the output of the generator to one of the inputs of the comparator and also to an input to the system under test, means for applying the output of the system under test to the second input to the comparator, and means for equalizing the two inputs to the comparator at zero frequency. In Fig. 1 the output of a variable bandwidth random signal generator 13 is applied to the input 11 of the system 10 under test, which may be a servo control system; if the system 10 is non- electrical, transducers are provided at the input and output of the system. The output of the system and the output of generator 13 are applied to a root mean square comparator comprising a difference amplifier 26, a root mean square rectifier 29 and an indicator 30. Adjustable attenuators 27, 28 allow the inputs to be adjusted to give zero output for equal inputs and a monitor 22 measures the output of generator 13 which can thus be standardised so that the indicator 30 indicates directly as a percentage of the standard duration of the input signal to the system under test. By adjusting the bandwidth of the signal applied to a system 10 and measuring the output, the relationship between error and bandwidth may be determined. Inspection of the curve will usually enable separation to be made of errors due to the basic transfer function, e.g. errors due to stiffness or compliance and errors due to stiction and backlash. Reduction in error can be achieved by adding to the signal applied to or derived from the system 10 a known proportion of the first derivative of the signal; this can be done by a network comprising resistors and a capacitor, Fig. 3 (not shown), or an inductance Fig. 4 (not shown). The random signal generator 13 may comprise an amplifier 14 tuned to 1, 000 cycles/sec., the output of which passes to a phase sensitive detector 15 gated by an oscillator 16 oscillating at 1, 000 cycles/sec. Signals at 1000 cycles/sec. are removed by a low-pass filter 17 which, together with an attenuator 18 and a shaping filter 19, forms a bandwidth control, these three units being adjustable with their controls ganged together. The output of the random signal generator may be controlled by an adjustable attenuator 21.

Abstract: 505,117. Switches held set and freed mechanically. SIMPLEX ELECTRIC CO., Ltd., and DAVIS, P. W. Nov. 5, 1937, No. 30439. [Class 38 (v)] Electric cooking or like apparatus incorporates a switch which is tripped open upon displacement of any member in a manner liable to expose live parts. Inside a switch chamber 11, mounted in a cooker, a switch operating mechanism as shown in Fig. 7 lies between two contact chambers, one of which is shown in Fig. 6. Co-operating with a fixed contact 16 is a contact 19 mounted on a spring strip 20 and moved by an insulating block 27 carried on a rod 28. Closing of the switch is effected by pressing down the handle 36 which, through a pin-and-slot connection 38 rotates a lever 35 pivoted at 39 against a spring 40, and through a rule joint linkage which consists of two links 33, 34 urged into a straight line by a spring 41, rotates a lever 32 and the rod 28 on which it is mounted, to close the contacts through blocks 27. Levers 43 and 48 pivoted at 42 and 47 respectively constitute the tripping mechanism. Any part of the cooker may be connected to the lever 48 by a Bowden wire 51 so that upon displacement of the part in a manner likely to expose live parts, one end of the lever 48 carrying a weight 49 is lifted and the other end rotates the lever 43 in a clockwise direction against a spring 42 until one end engages with and breaks the rule joint linkage 33, 34 to open the switch. The trip mechanism is also operated by removal of a front cover 60, Fig. 5, of the switch chamber 11 which allows a lever 58 to be rotated by a spring 62 and press down the trip lever 48. The Bowden wire may be operated by direct connection with a movable part or by connection with a spring-pressed plunger, and it may be replaced by any other mechanical, electrical or fluidpressure transmission. Indicating means comprises the word " on " on a boss 63 of the handle 36, and the word " off " on the end face 64.
