Abstract: 1,217,404. Valves; grommets. WORTHING- TON S.A. 5 March, 1968 [9 March, 1967], No. 10619/68. Headings F2H and F2V. In a rotary valve having a circular seat 58 and a closure member with a substantially rigid spherical face 65 joined by deformable portions 63 to a hub 61 splined to a rotatable shaft 40, the axis of the shaft 40 is offset with respect to the central axis C of the valve head 64 and the flow axis A of the valve so that when the shaft 40 is rotated to seat the face 65 on the seat 58, the face 65 first contacts the latter at P when further rotation of the shaft 40 causes the valve head 64 to pivot about P until the face 65 is fully seated, the portions 63 deforming. The shaft 40 is rotated by a ram 21 acting through a lever 50 fast on the end of shaft 40 which extends through a tubular portion (35) of the housing to which a bracket 42 supporting the ram is secured. A manual handwheel 53 on a shaft threaded into a bore of the bracket and acting on the end of the lever 50 remote from the ram 21 can be used to actuate the valve or as an adjustable stop. The shaft 40 is mounted in bosses 36, 37 integral with the housing or in a modification in bosses formed in a tubular arm connected in an aperture of the housing and having an L-shaped arm extending internally across the housing and supporting one end of the shaft 40. The seat 58 has an annular shoulder and is retained in the stepped bore by a ring nut 59 and in a modification can project into the valve chamber 32. A pointer on the lever 50 and indicia on the bracket 42 give an indication of the closure member position. A grommet 90 (Fig. 14) which surrounds the piston rod and allows it to move laterally in a slot of the housing of the ram has a square sectioned body 91 with a central bore and two end flanges 92, 93, each with a vent hole 94, 95 therethrough.

Abstract: A resistor for heating is composed of two powder-metallurgically produced sintered bodies each having a content of at least 20% by volume of electrically conductive particles joined together by electric resistance butt welding e.g. in argon and built up at least in the welding zone in part by a basic substance of crystal grains, which substance lacks or has insufficient plastic deformability and ductility during the butt welding and in part by an additional constituent uniformly distributed in the basic substance and having a softening temperature lower than that of the basic substance, the grain size of the basic substance being at most 20 microns in the welding zone and at most 10 microns beyond this zone.  The basic substance forms 20-90% of the material in the welding zone and comprises at least 25% of MoSi2 with at most 75% of Al2O3, and may include SiC, BeO, heat resistant silicides other than MoSi2, borides and aluminides.  The additional constituent forms 5-25% of the material in the weld zone and consists of a clay of the montmorillonite group or of a vitreous substance with a M.P. below 1720 DEG C.  It may comprise 60% upwards of SiO2 and a balance of one or more oxides of Na, K, Ca, Mg, B, Al and Ba.  The resistor comprises an incandescent rod-like heating section having butt-welded thereto rod-like terminal sections.  After sintering the two bodies to a non-porous state, they are butt welded by forcing them together and passing a current through them.  The terminal portions may be sintered powders comprising MoSi2 and an additioanl constituent consisting of Al2O3, SiO2 and a vitrifying substance e.g. an oxide of Na, K, Ca, Mg, B, Al and Ba.  These bodies may also be used as a heater section.  The sections are sintered in hydrogen up to 10 hours at 950 DEG -1450 DEG C and then in air for 1 hour.  The pressure is increased after the material has become ductile.  The welded parts are heated in air to form a glaze of silica.  The outer parts of the terminal may be of metal e.g. of an oxidation proof alloy, may be of molybdenum protected by surface siliciding, or may be a mixture of MoSi2 and SiC.

Abstract: 866,741. Folding chairs. LAFUMA FRERES. April 3, 1959 [April 4, 1958; Oct. 27, 1958], No. 11348/59. Class 52(2). In a reclining chair in which two U-shaped canvas covered frames 1, 2 are foldable together and are pivoted to two side plates 14, foldable U-shaped leg frames 15, 16 are crossed in the unfolded position to stabilize the side plates 14. The tubular metal leg frame 16 can be swung about pivot 29 against stud 31 and frame 15 can be swung about pivot 28 through frame 16 and against a stud co-axial with stud 31 but projecting from the opposite side of plate 14. Studs 31 thus limit the spread of frames 15 and 16 in the unfolded position and maintain plates 14 stationary with respect to the leg frames. Back 1 and seat 2 portions are tiltably mounted on plates 14 by means of a channel-section connecting member 18 (Fig. 8). The latter is carried on pivot 21 and is maintained at a given angle of tilt by the engagement between friction washer 26 on bolt 24 and the sides of slot 14a in which the bolt rides. The ends of portions 1 and 2 lie in the channel section of member 18 and are secured therein by bolts 17, 19. The back portion 1 is pivotable about the bolt 19 so that it can be folded on to portion 2. Canvas 3 is laced to portions I and 2 by rubber cord 4. Arms 13 are pivoted at 10, 11 and 12. The end portions of leg frames 15 and 16 are reinforced by the insertion of an additional tube (Figs. 12, 13 not shown).
Patent GB-453448-A (GB)
Title: Improvements in or relating to the manufacture of hose piping
IPC: B29D23/00
Filed: 1935-04-13
Abstract: 453,448. Hose piping. LAWSON, N., Windyridge, St. Cyres Road, Penarth, Glamorgan, and LEWIS & TYLOR, Ltd., Gripoly Mills, Cardiff. April 13, 1935, No. 11503. [Class 99 (ii)] [See also Group V] Hose piping is made by applying liquid latex to the interior of a canvas &c. tube 1 and then rotating the tube while the latex dries. The tube 1 is supported and rotation thereof effected by a plurality of rollers 2 which are themselves supported intermediate their length by brackets 8 and are all rotated in the same direction by a pinion 10. The ends of the tube are closed by plugs 4, 5, the plug 4 being bored and communicating with a cock 12 controlling pipe leads 13, 14, 15, 16. In operation, the cock 12 is actuated first to permit a small quantity of wetting agent from the pipe 14 to flow into the tube, the latter being rotated until the wetting agent is absorbed, and then to connect the tube by the pipe 13 to a latex container. The latex in the container is initially at low pressure, but when the tube is filled the pressure is increased until the fabric is impregnated to the desired extent; a negative pressure is then created in the container to empty the tube of surplus latex and the tube then rotated until the latex adhering to the tube has dried to a semi-solid state. This drying may be accelerated by actuating the cock 12 so as to place the tube in communication with a coagulating medium or a hot air pump by way of the pipes 15, 16 respectively. If desired the above operation is repeated until a lining of the necessary thickness has been built up ; further the plug 4 may be bored to function similarly to the plug 5. Final drying of the hose is effected naturally or by the application of hot air, and the hose may afterwards be vulcanized in situ by steam at a pressure of from 25 to 50 pounds per square inch.

Abstract: 912,229. Irradiation of thread or strip material. HEBERLEIN & CO. A.G. March 29, 1961 [April 14, 1960], No. 11522/61. Class 98 (1). Material in the form of ribbon, thread, or the like, is irradiated by being wound on to a drum, and then off that drum on to a second drum, the radiation source being introduced, in rod-like form, into the interior of each drum in turn. As shown, the process is carried out in a protective concrete housing 1. The drums 2, 3, supported between rollers 6, 7, are mounted on a carriage 4 which can move to and fro on rails. The radiation source 10 is provided in a tubular metal container, which can be pushed in from a side recess (Fig. 1, not shown) to lie along the central axis of either drum as required. One wall of the housing has two angled passages 14, 14<SP>1</SP> through which the material passes into and out of the housing. In carrying out the process, the carriage is first fixed in the position shown, when drum 2 is opposite the side recess containing source 10, and the source pushed into position within the drum. The strip material 13 is then introduced through passage 14, and wound on to drum 2. The source 10 is now removed, and the carriage 4 pushed along until drum 3 is in the position previously occupied by drum 2 (Fig. 3, not shown). The source 10 can now be introduced axially into drum 3, after which the material is wound off drum 2 on to drum 3. The source is again removed, and the carriage moved back again to the original position of Fig. 2. The source is once more inserted into drum 2, and a new length of material wound on to drum 2 while at the same time the original material 13 is wound off drum 3 and taken out through passage 14<SP>1</SP>. In order to produce a more uniform irradiation over the whole length of the material as it is wound on the drum, an auxiliary source 12, housed in a further recess 11, is brought close to the drum for part of the timo during the winding process. Practical details, such as suitable dimensions for the drums, winding speeds and times, thickness of material, and radiation dosages, are given.
