A nonwoven fabric of improved wet strength comprises 25-95% cellulose fibres (i.e. cotton or regenerated cellulose fibres) and 5-75% partially fused polypropylene fibres in bonding relationship therewith. The polypropylene fibres are distributed throughout the cellulose fibres but substantial areas of the cellulose fibres are free of partially fused polypropylene fibres whereby the fabric has absorbency for liquids. The bonded polypropylene fibres may cover no more than 20% of the fabric surface. The polypropylene fibres are generally ¢-2" long and 1-5 denier. The regenerated cellulose fibres can be rayon. The mixed fibrous web can be formed by carding, air-laying or waterlaying, or by sprinkling polypropylene fibres on or between cellulose fibre webs. The fibres in the web may be aligned. The polypropylene fibres can be uniformly distributed or may be in an intermitted pattern. The polypropylene fibres can be fused by heating to 325-400‹C by infra-red radiation, in an oven or by hotcalendering at 2-20 lbs/linear inch. The bonded web can be passed through chilled rolls to cool it. The specification also discloses: in Example III a cotton web bonded by sprinkling polypropylene powder to the web and hot-calendering; in Example V a web formed of a mixture of cotton and Vinyon fibres bonded by hot-calendering, in Example VI or cotton web bonded with hydroxyethyl cellulose.

Abstract: 1,164,996. Centrifugal separator. BABCOCK & WILCOX Ltd. 18 Nov., 1966 [19 Nov., 1965], No. 49153/65. Heading B2P. An apparatus for separating water from steam discharged from the evaporating section of a boiler comprises a pressure vessel 1, Fig. 1, containing a chamber 4 to which the steam-water mixture is fed through radial nozzles 2, Fig. 2. The chamber 4 is bounded internally by a cylindrical wall 5 from which a frusto-conical plate 6 extends upwardly to the wall of the vessel and a frusto-conical plate 7 extends downwardly and is spaced from the wall of the vessel to define an annular outlet 8. Helical strips 9 are welded flat against the interior of the vessel and extend downwardly for a complete turn at a decreasing angle of descent to the horizontal. A cylindrical sleeve 10 is positioned in the chamber 4 with its outer surface attached to the strips 9 and helical vanes 11 are positioned between the sleeve 10 and the plate 7 at the same angle to the horizontal as the start of the strips 9. Continuing downwardly from the vanes helical strips 13, Fig. 3, are welded to the strips 9 at an angle to the vessel wall to provide helical chutes of progressively decreasing steepness until just below the normal water level 27. Several reducing vanes 14 and a vortex eliminator, made up of crossed plates 19, 20, are provided in the lower portion of the vessel to diminish the swirl in the main body of water. An air release connection is shown at 22 and apertures (not shown) are provided at the level 21 for the discharge of separated steam. In operation, the steam-water mixture entering through the nozzles 2 into the chamber 4 strike against the cylindrical wall 5 whereby most of the water and steam are separated. The water and steam are then given a helical movement by the vanes 11 and enter the part of the vessel below the chamber 4 where the watar flows down the helical chutes and enters smoothly into the body of water. Any steam still present in the water is separated as a result of the helical movement down the chutes and escapes with the bulk of the already separated steam through the central passage bounded by the wall 5 and plates 6, 7 into the upper part of the vessel to be discharged through the apertures at 21.

Title: Apparatus for and method of determinging displacements using  moire fringes
IPC: G01D5/38
Filed: 1971-10-22
Abstract: 1370307 Photo-electric position measurement BENDIX CORP 22 Oct 1971 [23 Oct 1970] 49275/71 Heading G1A [Also in Division G4] Apparatus for measuring displacement comprising a pair of gratings 11, 13 relatively movable in front of photo-cells 21, 22, 23, 24 includes means 34 for interpolating between the grating lines and means for adjusting the spacing of the gratings. The gratings are selected to have a small number of grating lines per millimetre e.g. 40 in which case the apparatus is fairly insensitive to changes of the order of fortieth's of a millimetre in the spacing 30 between the gratings. As described a reading head 12 which is positioned adjacent their reflective scale grating 11, includes the transmissive indexing grating 13 and the four photo-cells 21-24 phase displaced from each other by 90 degrees. The cell outputs are fed in pairs via differential amplifiers 26, 27 which reduce electrical disturbances due to imperfections in the grating pattern, to a resistive phase divider 35 deriving 10 signals phase displaced by 36 degrees. These are fed via zero crossing detectors 40 to logic circuitry 42 which determines from the relative phase of the photocell outputs the direction of movement and pulses a reversible counter 45 connected to for example a visual display and a chart recorder. The position of the reading head is adjustable by loosening a screw (53), Fig.3 (not shown) so that a nut (54) may be moved in a slot (51) to produce the desired gap (30). The angle of the reading head and hence of the index lines relative to the scale grating is adjustable by an eccentric mechanism (56). Modifications: (1) only two photo-cells may be used. (2) the scale grating may be of cylindrical, frusto-conical or circular form. (3) either the scale grating or the index grating may be moved. (4) the scale grating may be of transmissive form.

Title: Basin constructions having cover assemblies
IPC: E04H4/08
Filed: 1970-10-20
Abstract: 1331488 Swimming Pool Covers R GRANDERATH 20 Oct 1970 [20 Oct 1969] 49651/70 Heading A4N An elongated basin or pool 1, such as a swimming pool, has a cover assembly comprising a shaft 8 on to which a cover layer 9 may be rolled, the cover layer comprising a plurality of buoyant elongate elements disposed transverse to the pool length and articulately inter-connected at their sides, the shaft 8 being located above or below the surface 2a of liquid in the pool so that the rolledup cover layer will deploy by itself under the action of gravitational forces or buoyancy forces respectively, and without the application of any other force, on the part 9a of the cover layer between the surface 2a and the roll 7 on the shaft. The shaft may be mounted in a housing 3 adjacent one end of the pool, the cover layer being guided by a guide 13 to pass through a slot 12 in a pool end wall 1d, and an overflow trough 4 being provided in the housing. In the gravity-deployed embodiment, the housing 3 is mounted above one end of the pool, Figs. 6, 7 (not shown). A manual, or motor-operated drive with a self-locking reduction gear may be provided to roll the cover onto the shaft 8. In order to support the edges of the deployed cover if a weight is laced on the cover the walls of the pool may be stepped below the liquid surface or may be provided with projections such as handrails, or two flexible rope or tape supports (78), Figs. 12,13 (not shown) may be provided, one end of each support being anchored to the end wall of the pool adjacent the housing containing the shaft, and the other end being carried by the leading edge of the cover layer and having a projection co-operating with a solenoid-operated locking device (80) in the opposite end wall of the pool. Each element of the cover layer may comprise a hollow plastic member (68), Figs. 10, 11 (not shown) having at least one sealed chamber therein, adjacent elements being inter-connected by inter-engaging hook-formations (68a) and (68b, c) there being means (68d), (71) to prevent relative longitudinal movement between the elements. The cover assembly may be arranged so that its height above the bottom of the pool can be varied to accommodate changes in the liquid depth in the pool.

Title: Tamper-proof sealing devices and items equipped with them
IPC: A61J1/05
Filed: 1974-11-18
Abstract: 1522798 Tamperproof seals AVON MEDICALS Ltd 10 Nov 1975 [18 Nov 1974] 49836/74 Heading B8T A tamperproof seal for an access opening, e.g. in a blood bag, includes a first tamperproof seal denying access until it has been destroyed and a second access-denying means to re-seal the opening made available on the destruction of the first seal, the second access-denying means being arranged to indicate disturbance from its sealing position. The seal comprises a tubular portion 5 attached by a weakened portion 8 to a block 9 integral with a strap 13 having a ring 14 at its extreme end and also an aperture part-way along its length. The second access-denying means is in the form of a plug 3 attached to the block 9 by a stem 21 and stud 22 received in a complementary opening in the block. Assembly.-To assemble the seal, the strap 13 is turned over through 360 degrees so that the aperture part-way along its length engages the plug 3 and the ring 14 is passed under the tubular portion 5 and received on a rebated portion 6 of the portion 5. A tubular member 1 having an access passage 26 therein, preferably closed by a puncturable diaphragm 4, is pushed into the tubular portion 5, leaving a larger diameter portion 24 between the end of the member 1 and a shoulder 7 of the portion 5. The assembly is then secured in an opening in a blood bag. In operation, a lift tab attached to the block 9 is pulled to rupture the weakened portion 8 to provide access to the passage 26. The act of rupturing the portion 8 causes the strap 13 to uncoil and the plug 3 is disengaged from the aperture in the strap. When it is desired to re-seal the passage 26, the plug 3, which is preferably frusto-conical, is pushed into the passage until it snaps behind the shoulder 7 with distortion of the portion 5. The force required to release the plug from the shoulder 7 is greater than that required to rupture the stem 21 or release the stem 21 and stud 22 from the block 9, thus providing an indication of attempted removal of the plug.

Title: Vehicle gas turbine drive arrangement
IPC: F02C7/36
Filed: 1976-10-15
Abstract: 1526570 Gas turbine engines; controlling DEERE & CO 15 Oct 1976 [17 Oct 1975] 49944/77 Divided out of 1526569 Heading FIG [Also in Divisions B7 and F2] In a control system for a vehicle powered by a gas turbine engine and functioning to control both turbine speed and the transmission ratio of a continuously variable gear, as in the parent Specification, the pointer 182 of an electrical meter 180, 184 indicates turbine speed over a range up to a marking 198 corresponding to maximum turbine speed and thereafter, in response to increased power demand, moves into a range between markings 198, 200 indicating an automatic adjustment of the transmission to cut-back ground speed relatively to a commanded ground speed. The marking 200 corresponds to a 50% ground speed cutback which is the maximum allowed by the control system whereafer any further increase in load results in slowing the turbine until turbine stalling speed is approached corresponding to marking 202. At that speed an automatic clutch should uncouple the turbine from the load, but should the turbine speed continue to fall the pointer moves into a range between markings 202, 204. During a manual mode of operation a switch 190 is positioned as shown so that the meter receives only the turbine speed signal N 1 and acts as a tachometer with a maximum deflection at 198. In an automatic mode the switch 190 is positioned to connect the meter with a summing junction 192 to which the N 1 signal is fed so that the meter again acts as a tachometer up to the marking 198. Any further increase in load results in the summing junction delivering to the meter an output consisting of N1 plus a ground speed error signal G1 ERROR so that the meter indication lies in the range 198-200. When conditions are such that the pointer passes the marking 200 an actuator 196 repositions a switch 194 so that the summing junction receives a fixed signal corresponding to 100% turbine speed instead of the signal N1, and the summing junction output then consists of the 100% turbine speed signal, the G1 ERROR signal and a turbine speed error signal N 1 ERROR.

A variable bandwidth filter comprises an amplifier with overall negative feedback, the bandwidth being varied without variation of gain by variation of the gain in the forward transmission path. In a low-pass embodiment, the forward path comprises a transistor 40 in common base connection, its input circuit comprising shunt R.C. circuit 30, 32 and series resistance 63 and capacitor 34, while the output circuit comprises a second shunt R.C. circuit 46, 45. The negative feedback path comprises a second transistor 52 in common emitter connection, in addition to a decoupled bias resistor 56 an undecoupled resistor 54 is provided to stabilize the gain. The gain of the forward path-which is always kept several times greater than unity in order that the overall gain may not appreciably vary-is varied, and with it the bandwidth, by means of diode 23 to which a control voltage is applied via terminal 22: variation of the diode bias varies the partition of the current through resistor 36 between the diode and the emitter of transistor 40, thereby varying the transistor gain without variation of the effective input impedance. The Specification includes a mathematical exposition of the mode of operation of the invention.
