Title: Autogeneously bonded non-woven fibrous structure
IPC: D04H1/54
Filed: 1975-04-11
Abstract: 1524713 Autogeneously bonded non-woven fabrics IMPERIAL CHEMICAL INDUSTRIES Ltd 31 March 1976 [11 April 1975] 14962/75 Heading D1R An unbonded non-woven bath comprising at least 20% by weight of crimped and/or potentially heat crimpable conjugate staple fibres is autogeneously bonded by upward passage through the batt of a fluid having a temperature sufficient to heat the batt to a temperature in excess of the softening point of the lower softening component but below that of the other component(s), and causing the batt to cool by upward passage of a cooling fluid through the bonded batt. The product is a batt of uniform density across its thickness. A staple fibre is defined as 0.5 to 6 inches long. Its decitex is preferably I to 50. Preferably 100% of the fibres are crimped or heat crimpable. The two (or more) copmonents of the conjugate fibres are arranged side by side or as lobes of a multilobal fibre or the lower melting component forms a sheath about a higher melting core. Symmetrical composite fibres e.g. sheath/core need to be crimped by mechanical action e.g. by a stuffer box. The number of crimps or potential crimps is preferably 2 to 4 per extended cm although there may be 10 or more per extended cm. The fibres exemplified are a side by side nylon 6 and nylon 66, polyethylene terephthalate core/polypropylene sheath, and a conjugate fibre of 50% nylon 66 and 50% nylon 11.  Preferably the fibres are corded to form a batt of density 0.005 g/cm<SP>3</SP> and the batt optionally cross-lapped to a thickness of 1.5 to 20 cm. The batt may be heated to activate the crimpable fibres without producing bonding and then recarded. Bonding may be effected by passing the batt over a fluidised bed of ballatins which evens out the upward flow of the heated fluid. A foraminous surface may be placed above the batt to prevent its disintegration by the fluid stream. The fluid may be air or steam. The steam may plasticise the fibres. The batt may be compressed by passage between heated plattens or through a pair of rollers and then cooled by an upward flow of cold air. The products had a density of 0.01 to 0.03 g/cm<SP>3</SP> and were used in the production of pillows, mattresses and upholstery.

Title: Improvements in or relating to crane winches
IPC: B66D1/14
Filed: 1921-06-01
Abstract: 164,330. Besnard, F. June 3, 1020, [Convention date]. Winches ; stopping automatically at end of run; self-sustaining gear.-Consists in a winch designed to permit stoppage and self-sustaming of the load at any predetermined height, and to permit lowering under brake control. For stopping automatically at any desired point, a countershaft 2 drives a screwed shaft 4 through worm or spiral gearing 3. During the lifting operation a nut 5, carrying a projecting arm 8, moves axially on the screw until it jams against the left-hand bearing 10. Further rotation of the screw then rotates the nut and causes the arm 8 to lift. one arm 9 of a two-armed lever pivoted on the shaft 9<b>. The other arm of the lever moves a clutch member axially to disengage the clutch. The distance of the nut from the bearing 10 is regulated to give the lift required, before jamming and declutching occurs. For self-sustaining, and braked lowering, a brake drum 13 is fitted in the clutch shaft. A band brake 14 is applied to the drum by a weighted lever 18. A one-way roller clutch comprising a notched ring 20 carrying spring-pressed rollers 22, serves to connect the drum rigidly to the driving-shaft when the load commences to run down, and thus applies the braking force of the band to the driving-shaft. Braked lowering may be obtained by raising the weighted lever 18 to a slight extent.

Filed: 1962-04-19
Abstract: 1,016,764. Fluid pressure servomotor control systems. ELECTROFLO METERS CO. Ltd. March 27, 1963 [April 19, 1962], No. 15381/62. Heading G3P. A pneumatic relay comprises chambers 40, 42, 44, 49, Fig. 3, (not shown) bounded by diaphragms 41, 45 which are connected to the rod 52 of a valve 43. An input signal 10 is fed to chamber 40 and a constant fluid pressure supply 15 is fed to a chamber 42a. The valve 43 controls the flow from chamber 42a to chamber 42 which provides the output signal 18. The output is connected to the chambers 44, 49 through a non-return valve 48 and a porportional bleed valve 47. The connection to chamber 49 is provided with a throttle 51 such that with an increase in the input signal, the output signal is given a boost which decreases with time as the pressures in chamber 49 increases to equal that in chamber 44. With a decrease in the input signal the time delay is not effective due to the non-return valve 48 and pressure in chambers 44, 49 leaks to atmosphere through valve 47. In a modification the input pressure is fed to chambers 44, 49 in a similar manner and the pressures act on a beam forming a hinged valve. The relay may be used in a boiler feed system Fig. 2 (not shown) in which the relay 19 provides a signal of the boiler load as measured by squaring the steam flow at 25. The output signal of the relay is combined with the boiler pressure at 30 and the feed pump output pressure at 29 to provide a signal from regulator 28 to a servomotor 35 which controls the pump driving means. Conventional valves 22 are provided actuated by servomotors 27 from a regulator 23 which is responsive to liquid level in the boiler at 24, water flow at 27 and steam flow at 25.
