Title: Improvements in or relating to injection molding process and apparatus for carrying out said method
Inventor: AN KENNETH WILSON SPILLM
IPC: B29C45/36
Filed: 1955-09-19
Abstract: 798,862. Injection-moulding tubular articles. PARKER PEN CO. Sept. 19, 1955, No. 26769/55. Class 87(2). A tubular article, e.g., a ball-point pen ink container is made by injecting plastic material into the annular space between a mould 2, Fig. 4, and a core 12. The material is injected downwardly through holes 21, 25 in a member 18, and pushes downwardly before it a slevee 31 which surrounds the core and keeps it centrally located. The sleeve is split over most of its length, to provide resilient tongues which grip the core, for a reason given below. The sleeve comes to rest at the bottom of the mould, its lower (split) end being accommodated within a recess 28 in a bushing 27 secured in a plate 26. Each core is fixed at its lower end to a plate 13. There are twenty-four moulds 2, and they are accommodated in a block 3. Fig. 2 shows the whole apparatus closed. When the apparatus begins to open, first an upper plate 29 carrying a sprue member 47 separates from the 3-26-13 assembly and a sprue puller 52 pulls the sprue 55 out of gate 48. Undercuts 57 in plate 29 initially retain sprue arms 53, and sprue projections 56 are broken away from the moulded articles. On further movement of plate 29, sprue projections 58 are pulled out of the undercuts, as in Fig. 3. Plate 29 opens to a degree determined by headed bolts 36. Then the 26-13 assembly separates from block 3, to a degree determined by bolts 42, the cores and moulded articles 30 being thereby pulled out of the moulds. Then plate 13 separates from plate 26, whereby the cores are pulled through the sleeves and out of the articles, as shown in Fig. 3, and the articles may be removed. When the sprue has been removed the apparatus may be closed again, and as it closes, each sleeve 31 is pushed back to the top of its mould by a step 46 on its core, the resilient tongues 33 having closed in to lie on this step.

Abstract: 444,405. Sliding - clasp fastenings. GRANT, H. B., 51, Crossway Lane, Perry Barr, Birmingham, and LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London. Sept. 19, 1934, No. 26980. [Class 44] A sliding-clasp fastener stringer is made by cutting off and affixing on a mounting tape the successive end elements of a strip of non- metallic elements substantially completely formed but still connected together, such strip being fed forward in a step-by-step manner by mechanism engaging with projections or recesses in the strip. For example, a rotary spindle B has a circumferential rib 5 engaging the recess 2 formed between the legs of one element and the rib is provided with a helical portion whereby the strip 1 is periodically moved forward and then held stationary while a cutting wheel 7 descends to cut off the end element 6 of the strip. The already separated elements are fed forward in pack formation and the end one 10 is moved down and placed on the mounting tape 17 by the descent of a plunger 12, the beaded edge 18 of the tape being at this time compressed by two jaws 13, 14 having moved inwardly. The element is firmly held on the tape by the expansion of the beading when the jaws move away and when the full complement of elements has been attached the stringer is immersed in an acetone bath to secure the elements, by a solvent adhesive action. The elements may be cut off by a guillotine knife and may be transferred by pockets in a wheel to lie under the plunger. Specifications 405,708 and 426,961 are referred to.

Title: Improvements in and relating to valves for use in fluid pumps
IPC: F04B49/24
Filed: 1935-10-08
Abstract: 461,362. Fluid - actuated valves. HORSTMANN, S. A., and HORSTMAN, Ltd. Oct. 8, 1935, No. 27806. [Class 135] A byepass valve for fluid pumps designed to remain open after the pump delivery pressure has fallen below that required to open the valve has a series of radial passages 24 in the valve member or head 14, the fluid flow past the ends of which sets up an ejector action when the valve is open so as to reduce the pressure inside the valve stem 15 below that on the inlet side of the valve head. The valve may be used to byepass a petrol pump when a trigger or other valve in the delivery pipe is closed. The valve 14, Fig. 2, is loaded by a spring 19 adjustable by a screw 21 mounted in a cap 18. A cap 22 conceals the outer end of the screw 21. The hollow valve stem 15 is grooved externally and is guided in a tubular member 16 held together with the cap 18 in a part 17 of the pump casing. The member 16 and cap 18 are clamped in place so as to be readily removable by a V-shaped clamping member 25 positioned by a bolt 26. The valve member has a cylindrical part 14a projecting into the orifice of the seat 10. The interior of the stem 15 communicates with the pump delivery chamber 12 by a passage 23 enlarged at one end. The passage 23 may however be dispensed with and the part 14a or the passages 24 modified to allow fluid to pass through them to the interior of the stem. In cases where the effective areas provided on the two sides of the valve head 14 are such that the inlet pressure would rise unduly before the valve opens, the interior of the piston is placed in communication with the pump suction chamber 13 before this pressure is attained by a spring loaded ball or other valve 28. As shown in Fig..4, the valve 28 is arranged in the pump housing 17, but it may be carried by the stem 15.
