Patent GB-1364190-A (GB)
Title: Fluid operated device
IPC: F15C3/04
Filed: 1972-07-25
Abstract: 1364190 Fluidic elements LEESONA CORP 25 July 1972 [26 July 1971] 34791/72 Heading G4P A fluidic OR gate comprises a chamber 22 divided by a diaphragm 32. Fluid entering the gate via inlet duct 18 or 20 exits via outlet duct 24 or 26, respectively, and passes to a common outlet 54. When fluid enters one inlet duct the diaphragm deflects to seal against a flange 44 surrounding the entrance to the other outlet duct, so preventing flow through the other inlet duct. The diaphragm prevents fluid flow from one inlet to the other.

Title: Apparatus for altering the cross-section of a hollow member
IPC: B29C57/04
Filed: 1971-07-23
Abstract: 1338506 Altering cross-section of a tube DYNAMIT NOBEL AG 23 July 1971 [23 July 1970] 34796/71 Heading B5A Apparatus for altering the cross-section of a tube 24 comprises a mould 1, and a mandrel 2 that includes a shaping ring 3. The ring 3 is rotatable and simultaneously movable to a position (as shown in Fig. 1) in which its axis of rotation is displaced from the longitudinal axis of the mandrel 2, the rotating ring 3 thereby forming a groove in the tube 24. As described, a hinged mould 1 mounted in a press is lined with a rubber matrix 1a that prevents slipping of the tube 24. The mandrel mounted on a shaft 8 is divided into two portions 2, 11 between which is interposed the shaping ring 3; the mould, mandrel and shaft include heating and cooling channels 23. The mandrel portion 11 is held stationary but is connected through ball bearings 20 to a guide 5 rotatable by a driving disc 9 from a variable speed driver 10. The ring 3 is connected through a needlebearing cage 22 to a slide 4, interconnected with guide 5, for rotation therewith. The slide can be displaced by a lifting cylinder 7, an amount determined by a setting screw 13. Hydraulic drive is provided by a system 21 (not further disclosed). Operation.-A thermoplastics tube 24 in a plastic state is placed in the divided mould 1, and a driver 19 moves a support 6 carrying the mandrel 2 towards the mould, the mandrel 2 serving to widen the tube end to form a socket. Hot water is circulated through the channels 23, and the driver 10 begins rotation of the guide 5, slide 4 and shaping ring 3. Simultaneously, the lifting cylinder 7 slowly displaces the axes of rotation of the slide 4 and ring 3, until stopped at 13, to form a groove in the tube end. After cooling the tube 24 by passing coolant through the channels 23, the rotation is stopped, the slide and ring axes returned to coincidence with the mandrel axis, and the mandrel removed from the tube by the driver 19. The groove formed receives a joint packing ring.

Title: An improved mechanism for winding strands subject to high constrictive force
IPC: B65H54/28
Filed: 1957-11-08
Abstract: 843,668. Winding yarns. OWENS-CORNING FIBERGLAS CORPORATION. Nov. 8, 1957 [Nov. 13, 1956], No. 34924/57. Class 120 (2). [Also in Group XVI]  An apparatus for drawing fibres or filaments, comprises means for forming the fibres into a strand, and collecting the strand into a wound package on a flexible tube supported on a rotating collet and is characterized in that the surface of the collet is made up of a plurality of segments radially movable with respect to and loosely retained on the body of the collet, and that the segments constitute a substantially continuous cylindrical surface so as to engage uniformly and thereby support the inner surface of the flexible tube. As shown, a bracket 15 supports a spindle 16 by means of a bearing 21. The body 24 of the collet is held on the spindle 16 against a tapered enlargement 26 by a lock nut 27. The body 24 has twelve longitudinal grooves 30 of dovetail cross-section. Each groove has a converging part 31 terminating in a narrow parallel sided portion 32. A T-shaped segment 34 extends the full length of each groove 30. The segments have straight sided neck portions 37 engaging portions 32 and joining a curved outer portion with a flared base 35. The segments are retained in the grooves by a head piece 40 and a collar 43, while a flat spring 46 presses each of the segments outwardly. In operation, a tube 12 is fitted over the collet, thereby depressing the segments 34 against the tension of springs 64. Material to be wound on the tube e.g. glass fibre, is then attached to the tube and the spindle 16 set in operation, e.g. through a clutch, not shown. As the speed of the spindle is increased the segments 34 are projected outwardly by centrifugal force, thereby applying pressure against the inner wall of the tube 12. In a modification, (Figs. 6 and 7, not shown) the segments are of C-shaped cross-section instead of T-shaped.

Abstract: 1429054 Making composite panels; stamping BRITISH AIRCRAFT CORP Ltd 23 July 1974 [24 July 1973] 35293/73 Headings B3A and B3Q [Also in Division E1] A method of forming a panel comprises positioning a metal facing sheet 1, 2 on each side of an interior sheet 3 of an alloy which exhibits superplastic behaviour, attaching spaced regions of the interior sheet alternately to each facing sheet, heating the assembly of sheets to a temperature at which the interior sheet exhibits superplasticity, and moving the facing sheets apart so that the interior sheet extends from one facing sheet to the other in alternate sequence. In one embodiment, the facing sheets are sealed one to the other to form an inflatable envelope assembly. The sheets are subjected to a welding operation around their peripheries at a region 8, Fig. 8. Spacer portions 4 in the form of strips, or portions 5 in the form of discs, are diffusion bonded to the sheets, and upon the moving apart of the sheets 1, 2 by inert gas under pressure a corrugated interior sheet or a dimpled interior sheet is formed. In a further embodiment, Figs. 4-6 (not shown), the welded regions are in the form of lines (6) or spots (7). To maintain flat outer surfaces, the sheets 1, 2 may be moved apart against press platens and the interior sheet may be of thinner gauge material than the facing sheets. The sheets 1, 2 may also be of a superplastic alloy, thus facilitating the forming of a non-flat panel.

Spikes 3, 4 having external heads provided with hollows 3, 4 engaging stationary pivots 7, 8 on the support 9 are provided at each end of the body 1. The pivot 8 is removable to allow the teazle to be removed and comprises the end of a screw 21. The elements 32, 33 comprise flexible washers made of, for example, natural or synthetic rubber. The washer 32 is gripped between the end of the body 1 and the cheek 25 and the washer 33 is mounted on a washer 22 and gripped against the outer face of the end 14 and the knurled head 35 of the screw 21. A number of teazle assemblies is mounted obliquely on the drum 15 and each is driven by a toothed wheel 29.

Title: Process for bleaching natural kaolin
Inventor: HEIMANN SIGISMUND
IPC: C04B33/10
Filed: 1961-10-03
Abstract: Kaolin is bleached by treating with titanium trichloride and/or titanium sulphate preferably in acid solution, whereby ferric iron is reduced to ferrous iron.  Neutralization if necessary is effected by aftertreating with alkali or alkaline earth bicarbonates or carbonate.  Titanium trichloride and titanous sulphate may be used as 0,1-3% on weight of kaolin and added as a solid or aqueous solution. The suspension may be acidified with mineral acids preferably before titanium salt addition. Hydrochloric or sulphuric acids may be used giving a pH preferably below 2.  Improved whiteness is obtained by aftertreating with pyrophosphate or highly condensed phosphates. Examples refer to bleaching with titanium trichloride alone, to a pretreatment with sulphuric acid and to a subsequent treatment with pyrophosphates, optionally followed by calcium carbonate addition. Comparison is made with the effects of sodium dithionite and sulphuric acid alone or with oxalic acid or sodium pyrophosphate and calcium carbonate.  Titanium dioxide is also used with sodium dithionite and sulphuric acid.
