Title: Improvements in or relating to the collection of gases from artificial silk and the like
IPC: D01D10/04
Filed: 1938-11-25
Abstract: 509,981. Artificial silk etc.; dyeing &c. apparatus. UFNOWSKI, W. Nov. 25, 1938, No. 34319. [Classes 2 (ii) and 15 (i)] Gases such as carbon disulphide and hydrogen sulphide, are removed from artificial silk threads, hanks, bobbins, staple fibre, regenerated cellulose foils, or the like obtained from viscose and similar substances, by passing the materials continuously through a water-filled tank under a bell-cover the margin of which dips below the surface of the water. The water is heated so as to promote evolution of gases from the materials and the gases are collected under the bell cover and then led away under their own pressure and are subsequently condensed. The materials are forwarded through the tank by passing them over rollers, or by moving them while supported on plates or tables, or by constraining them to pass along a passage with perforated walls. Premature evolution of gases before arrival of the material beneath the bell is avoided by supplying cold water at the end of the tank where the material enters. Means for heating the water after its arrival under the bell mav be provided. As shown in Fig. 1, artificial silk threads 13 pass into the tank 12 and under the hood 20 and are guided by rollers 16. Water of low temperature is introduced into the tank from pipe 23 at the place of entry of the threads and is guided between partitions 17. The water underneath the hood is heated by direct steam or hot water from pipe 18 to a temperature above 30‹C. so as to produce evolution of gases from the threads. The gases collect under the hood 20 and are guided under their own pressure through pipe 21, without being mixed with air, to a condenser where the carbon disulphide is collected. The residual hydrogen sulphide may be converted into sulphuric acid, oxidized to sulphur, or neutralized with waste lye. The tank is provided with an overflow 19. The hood 20 may be integral with the'tank 12 or it may be separate and capable of being raised, e.g., by weights 25 and pulleys 24. As shown in Fig. 4, the artificial silk to be treated is wound on bobbins which are placed on plates or tables 16<1> which may be secured to a belt conveyer. As shown in Fig. 7, viscose staple fibres are passed through the tank 12<11> between perforated partitions 16<11> either or both of which may be associated with a belt conveyer.

Title: Digital electronic timepiece
IPC: G04F1/00
Filed: 1972-07-25
Abstract: 1360932 Electronic watches DAINI SEIKOSHA KK 25 July 1972 [30 July 1971] 34739/72 Heading G3T An electronic timepiece gives a digital indication of time in a section 3 Fig. 1 and in addition gives an indication in a section 4, of the time interval between the time at a given moment and a predetermined time in the future i.e. remaining time before a fixed appointment. Preferably liquid crystal display panels are employed. An alarm may be operated at the termination of the predetermined time interval. The timepiece comprises a crystal controlled oscillator Fig. 2, (not shown) the output of which is divided to produce a 1 pulse/ sec signal which is fed to a counter. The counter produces a timing signal which is fed via a driver to the time indicating display section 3. The timing signal from the counter is fed to a further counter (not shown) which applies a signal having a frequency of 1 pulse/ 10 mins to a divider 20 Fig. 3. This produces signals on lines 20a, 20b, 20c at 1 pulse/10 mins, 1 pulse/20 mins, 1 pulse/40 mins respectively. These signals are each passed to respective AND gates 21, 22, 23 and according to the setting of a time-scale selector switch 25 for selecting the max. remaining time, the appropriate AND gate is opened to pass one signal e.g. the 1 pulse/10 min signal, via the respective NOT gate 21a to a shift register 24. The register has outputs to the remaining time indicating panels 26a to 26f. Initially all the panels are turned ON and after an interval, i.e. 10 mins with switch in position 1, a pulse is applied to the register from divider 20 causing the output in a line 24f to disappear so that panel 26f turns OFF. The remaining panels are sequentially turned OFF at 10 minute intervals. The remaining time is determined from the number of panels which are turned ON. Alternatively, the panels may be turned ON in sequence. The position of switch 25 is translated by a decoder 27 into a voltage to activate drive elements 28, 29, 30 which indicate the time scale (e.g. 1 hour, 2 hours, 4 hours etc) in numerical form, for the remaining time.

Abstract: 897,084. Cleaning tubes. FERRANTI Ltd., and BRADFIELD, G. Oct. 27, 1959 [Oct. 31, 1958], No. 39418/58. Class 99(2). [Also in Groups XIX and XXXV] A viscometer has an element 1 adapted for whole or partial immersion in a fluid, means 3, 6 for imparting torsional or longitudinal vibrations to the element 1, and means (not shown) for imparting additional or alternative vibrations to the element 1, these vibrations being of such an amplitude that any matter adhering to the surface of the element 1 is removed. The element 1 is formed as a nickel-alloy tube having a tubular intermediate portion 2 of magneto-strictive material. It is subjected to magnetic fields set up by a permanent magnet assembly 3 and the secondary windings 4, 5 of a transformer 6. The primary winding (not shown) of the transformer 6 is provided with a pulsed input thus causing the tubular member 1, 2 to vibrate at its resonant frequency in a torsional mode. In operation, the time taken for the amplitude of the vibrations to decrease from one predetermined value to another is a measure of the viscosity of the liquid in which it is immersed. In order to produce additional vibrations to remove matter from the surface of the member 1, an electronic oscillator generating a train of pulses of suitable amplitude and frequency is provided. The output of this oscillator is periodically applied to the primary winding of the transformer 6. In a second embodiment, a coaxial solenoid coil is provided around the portion 2 of the tubular member. The output of an oscillator whose frequency is the natural resonant longitudinal frequency of the member 1, 2 is applied to this coil, the input to the primary winding of the transformer 6 being disconnected, periodically. This is said to cause local cavitation and thus produce a greater scouring effect.

Abstract: 207,066. Dale, W. B., Hopkinson, R. A., and Hopkinson & Co., Ltd., J. Dec. 30, 1922. Cam actuated pumps; regulating delivery by throttle valves.-A cancelling device for minesignalling apparatus is actuated by a pump driven by the winding engine, cancellation being effected when the engine starts from rest. The engine shaft D carries cams C, Fig. 3, which depress respective plungers such as B to operate pumps having inlet valves J and outlet valves K, the plungers being restored by spring- controlled arms G. Fluid such as oil is thus pumped from the main chamber A through passage L, Fig. 2, to a cylinder containing the plunger M which is adapted to raise an arm N and so to turn a spring-controlled shaft 0 and lower an arm R which drags with it the cancelling lever T. Excessive pressure is relieved by a safety-valve 25, and further a centrifugal clutch may be arranged to disconnect the pump at high speeds, or, as shown, the arm N at the upper limit of its travel may engage lock-nuts 14 and so lift the stem 13, restricting at 15 the oil supply of the suction manifold 16, Fig. 3, which leads to the suction valves J, and thereby preventing the pump cylinders B from rising through their full stroke. Thus the pressure is maintained at a moderate value after cancellation has been effected. In order that the pressure may be released when the engine stops, a leak is provided at 19, Fig. 2, and is controlled by a friction-held sleeve 20. The arm N on its upward motion opens the leak by engaging nuts 22 and lifting the sleeve; on its downward motion at the stopping of the engine, it engages shoulder 23 and depresses the sleeve and so closes the leak ready for the next operation. Specification 186,373, [Class 118 (ii), Signals], is referred to.
