Title: Improvements in or relating to the treatment of webs of textile and other flexible sheet material
IPC: D06B17/06
Filed: 1957-08-31
Abstract: Apparatus for the treatment of lengths of flexible material, e.g. textile webs, comprises means for continuously feeding the material towards a treatment zone, a plurality of interspaced horizontal rollers arranged to be driven in an endless path towards an intake region, and means in or associated with the rollers for compacting folds of material formed between each pair of adjacent rollers against or adjacent the inner periphery of the roller path.  The fold-compacting <PICT:0885125/IV (c)/1> means may be part of the endless path which is doubled back upon itself so as to cause the folds of material to be laid one on the other.  As shown, rollers 30 are supported on an endless chain or belt arranged to describe a quadrilateral-feeding means comprise a pair of rollers 31, 32 between which sheet material 33 passes to be treated.  Rollers 30 are driven at a speed such that the sheet material may be guided between each adjacent pair thereof to form folds 34.  An endless belt having an upper region 35 is arranged in juxtaposition to part of the endless chain of rollers 30. Upper region 35 may constitute a moving surface against which the folds 34 are lifted up and compacted one on the other.  A pusher member 38 journalled in bearings 39 and reciprocated from a driving wheel 40 by way of connecting rod 41 transfers rollers 30 from a lower horizontal to a substantially vertical run, and at the same time material passing around each roller becomes a freed loop 46 which can be withdrawn onto a conveyer belt 47 arranged to extend horizontally through a treatment chamber (not shown).  In order to facilitate removal of loops 46 from rollers 30, the latter may be perforated for passage of a fluid, such as compressed air or steam, outwardly against the material in contact therewith.  The conveyer belt 47 may be positively driven if required, although the action of successively introducing the small loops 46 constituting the end of each ply 37 one behind the other onto the belt may suffice to cause the same to move forward. Where the belt is positively driven, however, this may be effected by providing teeth on a driving drum 48 of the belt, and by pivotally securing to the pusher member 38 a pawl 49 adapted to engage with the teeth on each forward stroke of the pusher member. To induce the rollers 30 to feed out the plies 37, driving means comprising a rack 50 and engaging pinion (not shown) may be provided.  Since, during travel around the endless chain or belt, the combination of roller 30, supporting arm 42 and pivot 43 faces oppositely to its start position direction. the apparatus may include a paddle member 51 having blades 52 designed to engage and invert each roller combination.  In a modification (not shown), the plurality of rollers and conveyer belt 47 may be immersed in a tank containing liquid with which the material 33 is to be treated.

Title: Improvements in and relating to weighing machines
IPC: G01G1/26
Filed: 1925-11-03
Abstract: 261,532. Davey, Paxman, & Co., Ltd., and Stebbing, R. C. Nov. 3, 1925. Steelyard apparatus.-In a weighing-machine of the steelyard type for weighing batches of two or more components in succession, lifting means, movable in the longitudinal direction of the steelyard are provided for lifting and traversing the poise weight, and longitudinally-adjustable stops are provided for terminating the longitudinal movement of the lifting means. Adjacent the steelyard 1 are arranged two guide bars 2 along which a block 5 may be slid by moving a lifting- shaft 9 longitudinally. By rotating the lifting shaft an arm 10 thereon moves a carrier 6 within vertical guides in the block, and fingers 7 on the carrier may thus be caused ta raise the poise weight 8 from the steelyard. Parallel to the guide bars 2 is a shaft 15 carrying two adjustable stops 18 bearing fingers 19. By rotating the shaft 15 either stop may be brought into the path of the block 2. The two settings are facilitated by a spring-pressed detent 23 engaging a notched disc 26 secured to the shaft 15, the notches allowing rotation of the shaft in one direction only. In use, assuming the stops 18 to have been correctly adjusted along the shaft 15, the poise weight is raised by rotating the handle 13, and the shaft 9 is moved longitudinally to bring the block 5 against the operative stop where it is locked by a catch 21 engaging the finger 19. The poise weight is lowered on to the steelyard and the first component of the batch is weighed. The shaft 15 is now rotated to bring the second stop 18 into position this movement disengaging the first stop from the block 5. The block may now be slid along the bars 2 into contact with the second stop and the second component may be weighed.

Title: Improvements in or relating to the concentration of the carotenoid content of a fatty oil
Filed: 1947-10-16
Abstract: The carotenoiel content of a fatty oil is concentrated by contacting said oil with a low-boiling solvent for said oil, said solvent having a critical temperature not substantially higher than 450 DEG  F., the temperature of contact being within the range at which the solubility of the oil in the solvent decreases with rising temperature and between about 100 DEG  F. below the critical temperature of the solvent and not substantially above said critical temperature so as to form solvent and oil phases between which the oil is distributed, and the pressure being at least sufficient to maintain the solvent in the liquid condition at a temperature employed, and recovering from said oil phase the carotenoiel concentrate.  Preferably the extraction step is carried out in a counter-current extraction zone which is refluxed by oil separated from the extract phase.  As solvents there may be used low boiling paraffins or olefins, e.g. ethane, propane butane, pentane and hexane, and also ammonia, dichlordefluoromethane, dimethyl ether, methyl fluoride and other halogenated hydrocarbon.  An example is given.

Title: Improvements in or relating to false twisting machines
Inventor: SCRAGG ERNEST PHILLIP RUSHTON
IPC: D02G1/02
Filed: 1955-09-30
Abstract: 801,343. Textile 'spinning and twisting machines; crimping yarns. SCRAGG & SONS, Ltd., E. June 20, 1956 [Sept. 30, 1955], No. 27825/55. Classes 120(2) and 120(3) A machine for false-twisting yarns (as in a crimping process) comprises a take-up tube resting on a roller whereby it is rotated and a pair of feed rollers (around which the yarn is lapped) disposed one above and one below the false-twisting unit and each resting on a separate drive roller which imparts independently variable speeds thereto: one movement of displacement means simultaneously disengages the twisting unit from its driving belt and lifts the feed rollers from their drive rollers and reverse movement of said means restores all components to their former positions and operation. In the machine shown, a yarn is fed from a bobbin 27, through a tensioning device 28, around a feed roller 20, through a heating device 26 and a twist tube 13, over a feed roller 19 and a guide 30 to a tube 31 on which the yarn is wound into a package. Tension in the yarn may be adjusted to effect controlled relaxation or stretch, e.g. by increasing the speed of roller 20 or 19 or varying the speed of a roller 32 driving the tube 31. Movement of a handle 29 from the position shown rotates a shaft 14 to move a cam 15 which actuates a pushrod 16 to swing a false-twisting unit 10 about a post 12 against the constraint of a helical spring (not shown) so that the tube 13 is disengaged 'from its driving belt 11: rotation of the tube 13 may be arrested by a brake (not shown) also actuated by the shaft 14. Simultaneously therewith, cams 24 and 25 engage and rotate discs 23 to raise pivoted U-brackets 17 and 18, thereby disengaging the rollers 19 and 20 from their driving rollers 21 and 22 (variation in the speed of which effect the yarn tension control) and therefore move the yarn laterally from contact with the plate in the heater 26. The movements of the shaft 14 may operate a switch to control electrical supply to the heater.

Abstract: 750,591. Subaqueous structures. MAUNSELL, G. A. Sept. 27, 1954, No. 27846/54. Class 68(2) A precast reinforced concrete tubular subway S, Fig. 1, is secured in a wholly submerged position below water level H but above ground level K by means of piles F driven through guide holes E preformed in the concrete structure, each pile F being rigidly connected to the subway after driving. As shown the subway  is formed of long segments such as S1, S2, Fig. 2, which are closed by bulkheads D1, D2 and floated by means of floats L and connecting wires M into the required position. To secure the additional segments S1 to that S2 which is already secured by piles F, a tapered steel pin P projecting from the central wall U of segments S1 is caused to enter a circular orifice R in the face of the central wall of segment S2, the abutting faces of the segments, being subsequently grouted together and the adjacent bulkheads removed. The subway may be formed with two carriageways A separated by the central wall U and two smaller ducts C separated by crosswalls V from the carriageway A. The holes E for the piles F are formed in the walls U, V, some of them being vertical and some inclined. The weight of water displaced by a segment is slightly less than the weight of the segment, the centre of buoyancy B being vertically above the centre of gravity G. Cylindrical steel shafts T1. T2, give access to the airfilled tubular compartments A when the segments are being placed in position.

Abstract: 1477256 Automatic control of high voltage generator OPTISCHE INDUSTRIE DE OUDE DELFT NV 2 July 1975 [9 July 1974] 27873/75 Heading G3R A supply circuit for an image intensifier includes a transistor oscillator with a transformer having a feedback winding and connected to a voltage multiplier. A control circuit includes an auxiliary winding in series with the feedback winding, and a control transistor connected in series with the auxiliary winding for controlling the power supplied by the oscillator. As shown, a three stage image intensifier BV is connected to the output of a voltage multiplier VM supplied from a push-pull oscillator including transistors Ql, Q2 and a transformer T having main primary windings L1, L2 and a centre-tapped feedback winding L3, L4. The transformer also has auxiliary windings L5, L6 which respond to the current drawn from the oscillator in order to turn on a control transistor Q3 when the current drawn exceeds a pre-set level. The control transistor is biased by a diode and resistor network so as to draw a constant current when turned on. Base current is thus diverted from the transistors Q1, Q2 to an extent such that the power supplied by the oscillator and the brightness of the image produced by the intensifier BV are maintained at constant levels. A diode D3 provides temperature compensation for the network biasing the control transistor Q3.
