Title: Improvements in the manufacture of fishing rods
IPC: B29C70/86
Filed: 1968-01-19
Abstract: 1,210,541. Fishing rods. ANSTALT FœR WALZPRODUKTE UND VERSTARKTEPLASTIK. 19 Jan., 1968 [20 Jan., 1967], No. 2919/68. Heading A1A. [Also in Division B8] Fishing rod elements are made by forming a continuously moving core 25, Fig. 2, from a series of core rods of lightweight material disposed in abutting end-to-end relationship, enclosing the core 25 with a tubular layer formed by threads 8 impregnated with plastics material and disposed substantially parallel to the core axis, winding at least one thread or strip 18 helically around the covered core assembly, passing the resultant product through a heating zone for setting the plastics material, and cutting elements of the desired length from the product emerging from the heating zone. As illustrated, the core rods 25 may all be of similar frustoconical shape, the successive core rods being oriented in opposite directions. In such instances the product will be severed along the liner 30. The core rods may be of expanded plastics material. Fig. 1 (not shown) illustrates an apparatus for carrying out the method. Frustoconical portions (2) are housed in two hoppers (1), one hopper housing those portions (2) that have their long end facing forwardly and the other hopper housing those portions (2) that have their large end facing rearwardly. The portions (2) drop from the hopper (1) alternately under the control of a photo-electric device 5 that causes the appropriate hopper to open after a core has been fed longitudinally past the photo-electric device 5. Spring biased rollers (4a) move the cores away from the hoppers to further rollers (4), the rollers (4a) tending to move the cores faster than the rollers (4) to ensure that the cores shall all be in endto-end abutting relationship. Glass threads (8) pass through tanks (9) containing polymerisable plastics material; they then pass through guides (21, 22) and through pre-shaping and shaping dies (11 and 12) spreading the impregnated threads (8) into a tubular covering around the core constituted by the rod portions (2). The resultant product then passes through a plate (14) carrying bobbins (15), the plate being rotated about the product to wrap the ends therearound from the bobbins (15). Thereafter the whole passes through an oven (19) causing the plastics material to polymerise and set hard. A cutting device (23) is associated with an abutment (24) which is movable in the direction of travel of the product against the action of a spring (25).

Title: Improvements in or relating to automatic regulating valves for fluid flow
Inventor: TRIBE LEONARD THOMAS
IPC: G05D16/10
Filed: 1964-01-24
Abstract: 1,096,434. Valves. PLESSEY-UK Ltd. Jan. 20, 1965 [Jan. 24, 1964; April 15, 1964], Nos. 3145/64 and 15515/64. Heading F2V. A pressure-regulating valve comprises a sleeve 24 which slides within a valve housing 26 held by fins 27 in the fluid flow line. The upstream end of the sleeve 24 is formed with a perforated flange 31 joining the sleeve to a central portion 30, which slides on a hollow stem 29 of the valve housing. The downstream end of the portion 30 has an end 32 of greater diameter and abuts a collar 33 of the housing whilst the downstream end of the sleeve 24 is also of great diameter. A passage 36 is connected to atmosphere. To alter the fluid flow the sleeve 24 moves to and from its seat 22 under the action of the downstream pressure acting upon one side of the end 32 after passing through bore 28, with atmospheric pressure on the other side of the end 32 and a spring in opposition. Action of the upstream and downstream pressures on other parts of the movable sleeve 24 is otherwise balanced. In a modification the end 32 and the collar 33 are discarded whilst a fixed restrictor replaces the perforated flange 31 and a variable restrictor partly blocks the passage 36 to atmosphere. These restrictors are such that the flow therethrough is virtually always critical and movement of the sleeve 24 is achieved by the downstream pressure on the face 31, two springs and the pressure on the other side of the fixed restrictor opposing this. Grooved surfaces are provided in all cases to limit fluid leakage around the sleeve.

Abstract: 764,999. Buffing wheels. EVANS, A. J. S (.Codman Co., F. L. & J. C.); Feb. 4, 1955, No. 3441/55. Class 60 A buffing wheel comprises an annulus of fabric which is ruffed at the outer circumference of the annulus so that the length of the outer circumference of the annulus is shorter than the inherent length of the fabric at the circumference, the annulus being formed from a plurality of plies of bias-cut fabric sown together, before the fabric is ruffled in forming the annulus by stitching which in the annulus lies substantially transverse to the radii of the annulus which intersect it. The stitching may be, in the annulus, substantially in the form of a continuous spiral having several convolutions. The annulus may be one of a pair connected together at their inner circumferences by means of fabric; the fabric by which the two annuli are connected may be integral. with the material from which the annuli are formed. The or each annulus may be rigidly constrained at its centre but not at its outer circumference so that the axial width of the annulus is greater than that at its centre; the axial width of the annulus may be not more than a little greater than the width of the fabric before being ruffled to form the annulus. The annulus may be ruffled at its centre, the extent of the ruffling at the centre being greater than that at the outer circumference. A cylindrical blank B, Fig. 5, is formed by assembling a plurality of layers of biascut fabric on a mandrel; a single piece of fabric may be wound spirally or small pieces of fabric may be used, the innermost and outermost layers preferably each consisting of one piece of fabric. The layers, while on the mandrel, are sewn together, the stitches being on separate parallel circles or on helices S extending in opposite senses and leaving the plies at the central portion of the cylinder free from one another, The blank B is then transferred to the surface of a mandrel, Fig. 6, comprising separable parts 10, 12 having an outer diameter corresponding to the internal diameter of the blank and spaced apart to provide an annular slot 14 not markedly greater in axial width than twice the thickness of the blank; the central portion of the blank is then forced radially down into the slot at all points around the circumference until the position shown in Fig. 8 is reached, wherein the ruffled inner circumference 16 of the blank is brought to the desired inner diameter. The die is opened and the blank withdrawn. To complete the wheel, the annulus has its inner edge 16 mounted on a hub 20 e.g. of chipboard or the like and conveniently secured thereto by adhesive. Two endplates 22 e.g. of hard, stiff, vulcanized fibre are applied to the face of the hub 20, strong axial pressure being exerted until the adhesive sets, so that the fabric at the inner periphery is still further compressed and densified. A circumrential row 24 of stitches may be applied through the annulus just outwardly of the sideplates.
