Patent GB-1461283-A (GB)
Title: Mechanical presses
IPC: B30B15/28
Filed: 1974-02-12
Abstract: 1461283 Moulding press MASCHINENBAU UND VERTRIEBS GmbH 12 Feb 1974 [12 Feb 1973] 06299/74 Heading B5A A cylinder A and a pressure release valve B are attached to the ram of a mechanical press for compacting powder, and a punch is attached to a piston 8 whereby the drive between the ram and punch is effected through an hydraulic cushion 8<SP>1</SP> connected to the valve B. When the pressure exerted by the punch reaches a predetermined value a piston 4 of the release valve is depressed by the pressure of the hydraulic cushion whereby fluid escapes via a duct T to a reservoir, thereby allowing the ram to continue its downward movement whilst the punch remains stationary. Closure pressure of the release valve is provided by a pump 1 supplying pressure fluid from the reservoir to duct X, such pressure being controlled by an adjustable valve 5; leakage of fluid past the piston is returned to the reservoir via duct L. Excess movement of the ram relative the punch is prevented by a switch 11 actuated by a projection 13 on the punch. An adjustable valve 7 controls the pressure acting on the upper end of the piston 4.

Title: Improvements in and relating to the casting of metals
IPC: B22D13/02
Filed: 1940-04-08
Abstract: 540,229. Casting-machines ; cores. STANTON IRONWORKS CO., Ltd., and WILSON, P. H. April 8, 1940, No. 6327. [Class 83 (i)] An explosive shell or other hollow body with one open end is made by lowering a refractory core 3 to a predetermined position in a rotating mould 1 containing molten metal 10, the core being positively rotated, at least when in its lowest position, at the same speed as the mould, which speed is so regulated that the metal remains in contact with the core. The core may be rotatably mounted and be adapted to engage the mould in its lowest or other desired position, e.g. by a bevel 8. The core serves to vent the metal and preferably applies a slight pressure to it during the final stage of the core's depression and during solidification.

Title: Nuclear reactor fuel element
IPC: G21C3/18
Filed: 1967-02-10
Abstract: 1,129,530. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 10 Feb., 1967 [7 March, 1966], No. 6470/67. Heading G6C. A superheater fuel element comprises a tubular member 32 secured at each end to a tube sheet 10, 12, between which sheets extends a plurality of tubes 14, 16 penetrating fuel pellets 26. The pellets 26 are retained in position by means of springs 28 which are compressed between the tube sheet 10 and washers 30. A body of stainless steel wool 29 interposed between a pair of washers 27 separates each stack of pellets 26 from the tube sheet 12. The fuel element is employed in a boiling water reactor, the water being in engagement with the tubular member 32 and the steam produced being directed first through the tubes 16 in the direction indicated by arrows 22 and then by a deflector 20 through the tubes 14 emerging from these tubes in the direction indicated by arrow 24. The tubular member 32 has a flexible section 31 which permits relatively free axial movement between the interconnected tube sheets 10, 12. In order to reduce the stresses developed in the tubes 14, 16 due to the differential thermal expansion of these tubes in operation, the fuel element is manufactured in a prestressed condition. The tubes 14, 16 and the tubular member 32 are all made of a suitable Ni-Cr alloy. In assembling the element the tubular member 32 and the first pass tubes 16 are welded to the tube sheets 10, 12. The second pass tubes 14 which are somewhat shorter than the tubes 16 are welded to one of the tube sheets and then the element is compressed until the end of the tubes 14 are flush with the other tube sheet, these tubes then being welded to this tube sheet. This provides a prestressing such that at room temperature the tubes 14 have a tensile stress and the tubes 16 have a compressive stress. In a modification in which the tubular member 32 has no flexible section 31, the tubes 14 are somewhat shorter than the tubes 16 which are in turn shorter than the tubular member 32 and a similar method of assembly results in the tubes 14 having at room temperature a considerable tensile stress, the tubes 16 a much less tensile stress and the tubular member 32 a compressive stress.

A collapsible table, which may fold into a cabinet, comprises flaps 11 each associated with one pair of links 14-15, 16-17, 18-19, or 20-21, of each of two parallel linkages 12, 13 which are arranged in an erected position to lie outside the flaps 11 but to provide support for them. The flaps 11 are arranged to move to overlie one another when the linkages are folded. Adjacent pairs of links are pivoted to one another and to a flap 11 at the end of a cross-bar 31, the other end of the flap 11 has a ramp 33, which rests on another cross-bar 32, and a chamfered recess 34 so that when the table is being closed the flap 11 passes between the two cross-bars 31, 32. The pair of links 14, 15 are attached to a wall support with a fixed pivot 23 and a movable pivot 24 slidable in a guide 25. To facilitate opening and closing the table, a handle 26 is provided which is pivoted at 22 or the handle may be a continuation of the last link. A rounded end flap 35 supported by two bars 39 may be used as an ironing board. In a modification shown in Fig. 7 the table is supported on four legs 54 attached to each end of the 'lazy tongs' linkage, by pivots 57, the links 56 being extended to form side rails which are interconnected by a transverse handgrip 55, the legs 54 are of channel-section and have extension legs 65 pivoted to them so that they fold round and fit the channel-section with hooks 70 fitting over the top of the leg 54.

Abstract: 125,093. Cochrane, F. May 8, 1916. Mordant dyes, dyeing with.-Textile fabrics are dyed in such manner as to appear invisible when viewed from a distance, by first padding in a solution of a dye capable of producing two or more colours by after-treatment with metallic salts, then developing a uniform ground shade by means of a suitable metallic salt, and then applying other suitable salts, by hand or otherwise, in promiscuous patches to develop one or more further shades upon the ground. In an example, the fabric is padded in a solution of cutch, fustic, or sumac, the ground shade is then developed by passage through a bath of aluminium salt, and then bichromate of potash and iron salts are applied in promiscuous patches; the fabric is then folded and allowed to stand to allow the shades to blend, and is finally dried.
