Title: Treatment of sheet material
IPC: D06H3/12
Filed: 1971-06-14
Abstract: 1358868 Guiding webs MOUNT HOPE MACHINERY Ltd 14 June 1971 27736/71 Heading B8R [Also in Division D1] Apparatus for straightening and aligning the thread formations of woven or knitted web material includes a series of rollers comprising, in order of the sequence of their engagement with a web 30: rollers 1, 2 and 3 of which 1 and 3 are braked; driven rollers 4, 5 mounted on respective curved axles 60, 62 which can be rotated to correct bow distortion of the web 30; a guide roller 6; a skew-correcting roller 7 carried on a pivotally mounted frame 124; and further rollers 8 to 11. Automatic positioning of the frame 124 and of the axles 60, 62 to straighten and align the web threads is effected by a control circuit responsive to signals derived from detectors 184 which sense skew and bow distortions in the web path between rollers 8 and 9. Further, the rollers 4, 5 and 10 are driven at different speeds so that different degrees of tension are applied in each zone defined between these rollers, these degrees of tension being so selected that the minimum tension consistent with the optimum performance of each of the operations of feeding, bow correction, skew correction and detection is applied in each of the corresponding zones. A suitable circuit for effecting the required speed control is described with reference to Fig. 6 (not shown). A modified construction in which the straightening operations are carried out in the reverse order to that of the apparatus of Fig. 1 is described with reference to Fig. 6 (not shown).

Title: Improvements in hydraulic pumps
IPC: F04B1/12
Filed: 1946-09-17
Abstract: 646,371. Reciprocating pumps for liquids. BEACHAM HYDRAULIC CO., Ltd., and BEACHAM, T. E. Sept. 17, 1946, Nos. 27-782/46 and 3832/47. [Class 102(i)] [Also in Group XXVI] In a hydraulic pump comprising a swash-plate mounted on a conic crank so as to be freely rotatable thereon and adapted to reciprocate piston units having their axes parallel to the axis of rotation of the conic crank and biassed axially towards the face of the swash-plate, the friction preventing the swash-plate from rotating, the plane of the face of the swashplate passes through the point of intersection of the axis of the conic crank and the axis of rotation thereof, the pistons being free to turn in their cylinders. A conic crank 2 solid with a rotary drive shaft 1 supports, through a ball-bearing 33 a swashplate 3 the face of which is engaged by the spherical or coned ends of pistons 4a reciprocating in cylinder 8a. The cylinders comprise bores in a cylinder block 9 into the enlarged ends of which sleeves are screwed, the sleeves also serving to guide piston return springs 5. To the ends of the block 9 hoods 23, 24 are bolted to house the mechanism. Inlet valves 14a at the cylinder ends remote from the swash-plate are housed in counterbores in the block 9 and their seatings secured therein by screwed sleeves 42. The valve seatings are coaxial with eccentric enlargements of the cylinder ends, the enlargements co-operating with radially disposed outlet valves. As shown, the cylinders are of two diameters but all may have the same diameter; the end of the drive shaft is supported in a bearing 32 in the cylinder block but this may be omitted if an additional bearing is provided on the drive shaft 1. The construction results in a substantially pure rolling movement between the swash-plate 3 and the ends 6 of the pistons, there being also a slight oscillation at the region of contact therebetween, which is absorbed by the natural resiliency of the materials used. Weights 7a, 7b rigid with the drive shaft balance the centrifugal forces and the couple generated by the swash-plate and the reciprocating movement of the pistons (see Group XXVI).

Filed: 1964-07-10
Abstract: 1,020,694. Spring clips. A. V. RAYMOND, [trading as A. RAYMOND DRUCKNOPF UND METALLWARENFABRIK]. July 10, 1964 [July 25, 1963], No. 28657/64. Heading E2B. [Also in Division F2] A resilient stud for use as a fastener or closure device comprises a head 14 and a shank 11, the shank comprising a core and a series of lugs 17 each of which projects radially from the core and has a part-actuate retaining surface 18 facing the head and lying approximately in a plane perpendicular to the axis of the shank, the retaining surfaces of circumferentially adjacent lugs being offset along the length of the shank. The plug is formed from an elastic synthetic resin material and when used as a fastener for securing two apertured members together the shank enters aligned apertures in the two members so that the head abuts the surface of one member and the retaining surface 18 of one of the lugs engages the under surface of the other member. The head 12 is in the form of a resilient skirt 14 which has a dished under surface 15 and in use the skirt 14 is flattened against the adjacent member so that the two members are held permanently under slight compression between the skirt and one of the lugs. The lugs shown are arranged on a helix each lug occupying approximately one quarter of the circumference of the core and four lugs completing each full turn around the core. In a modification the lugs are arranged on the core in the form of a two start helix each lug extending around 60 degrees of the circumference of the core so that six lugs complete a full turn of the core. With this arrangement pairs of retaining surfaces 18 are aligned on opposite sides of the shank. In a further modification each lug extends halfway around the circumference of the core and lugs on opposite sides of the core are staggered by an amount equal to half the depth of a lug. Instead of having a head with a skirt as shown the head can be made to grip a cable or a strip beading and to attach these to a support engaged by the shank. In each case the underside of the head is made concave so that the head is flattened in use.

Abstract: 998,047. Drafting apparatus. W. MEGENER, and H. BECHLENBERG. July 26, 1962 [July 29, 1961], No. 28699/62. Heading D1D. [Also in Division G3] In a system for maintaining uniformity in a sliver passing between drafting rollers, movement of a rounded bar extending across the whole width of the sliver, and urged towards the sliver, by leaf springs at each end of the bar, controls the relative speeds of the rollers. In Fig. 1 a sliver 3 is drafted between rollers 1,2 running at different speeds. A bar 4, mounted at each end of leaf springs 5, presses against the underside of the sliver and thus varies in position according to the drafting force in the sliver. Strain gauges 6, detecting movements of springs 5, are arranged in a bridge-amplifier circuit 7 which, automatically controls the relative speeds of rollers 1,2 in such a manner as to maintain the drafting force constant. In modifications (a) strain gauges are associated with both sides of the leaf springs for temperature compensation, (b) bolometers are utilised to detect spring movements, (c) movements of the bar or springs influences a differential inductance, a differential capacity, light falling on a photo-cell, or a piezo-electric device to control the relative speeds.
