Filed: 1971-08-17
Abstract: 1299819 Pipe couplings; joint-making packing RAYCHEM CORP 17 Aug 1971 [8 Sept 1970] 38533/71 Headings F2B and F2G In order to seal a coupling, such as a union between hydraulic lines or between an adapter 3 and an hydraulic cylinder, compressor or pump 1, a metal V-ring seal 4 is formed from an alloy which, when cooled, is mechanically weakened by transition from an austenitic to a martensitic state. The coupling is engaged with the seal in the weakened state, so that it readily conforms to the sealing surfaces, without scuffing them. Preferably, the memory property of the alloy for its pre-cooled shape is utilized, by deforming it while cold, so that, on returning to the normal temperature, it changes shape (Figs. 6 and 7, not shown) or increases its sealing pressure (Figs. 2 and 3, not shown). A sleeve 10 is made of the same or a similar alloy in order to effect a joint by shrinking on to tubing 11, as described in a parallel disclosure. On tightening up the nut 5, sealing surfaces (7 and 13) are resiliently interengaged (Figs. 4 and 5, not shown).

Title: Method and agent for making cellular vinyl aromatic polymers
IPC: C08F2/02
Filed: 1957-11-20
Abstract: A method of making a cellular body from a vinyl aromatic polymer comprises expanding a polymeric composition consisting essentially of at least 80 per cent by weight of at least one monovinyl aromatic compound chemically combined in the polymer molecule and having neopentane in which the polymer is insoluble uniformly dispersed throughout, by heating the composition to a temperature above the softening point of the polymer and above the boiling point of the neopentane.  The polymeric composition can be formed by mechanical mixing or by polymerizing the monovinyl aromatic compounds in admixture with the neopentane. Monovinyl aromatic compounds mentioned are styrene, vinyl-toluene, vinylxylene, ethylvinylbenzene, ethylvinyltoluene, isopropyl styrene tert.-butylstyrene, chlorostyrene, dichlorostyrene, fluorostyrene or ar-chlorovinyltoluene.  As copolymers there may be used a -methylstyrene or methylmethacrylate or 0.01 to 0.5 per cent of a divinyl aromatic compound, e.g. divinylbenzene, divinyltoluene or divinylethylbenzene.  In the polymerization benzoyl, lauroyl or di-tert.-butyl peroxides, cumene hydroperoxide, tert.-butyl perbenzoate or di-tert.-butyl perphthalate may be used as catalysts. Cellular products obtained using e.g. 8 to 15 grams of neopentane per 100 grams of polymer can be expanded to greater volume by continued heating or by subjecting it to repeated successive heating and cooling operations.  In an Example (1) styrene containing benzoyl peroxide is mixed with neopentane at -70 DEG  C.  The mixture is heated in a glass ampoule up to 125 DEG  C.  The solid polystyrene containing dispersed neopentane obtained is heated in air at 130 DEG C. to give a foamed polystyrene.  In generally similar processes there are employed in place of styrene (4) a mixture of 99.9 per cent styrene with ethylvinylbenzene and divinylbenzene; (5) a mixture of dichlorostyrene isomers.  In Example (6) polymerization is effected in water containing methyl cellulose.  The granular product is ground and moulded at 135 DEG  C. to give a cellulose body. Comparison experiments describe the use of isopentane and n-pentane in place of neopentane.

[Also in Divisions G1 and G3] A centrifuge for measuring the deflocculation of a clay suspension comprises two compartments having windows for the passage of light through the compartments and photoelectric means for comparing the optical density of material in the compartments. The centrifuge comprises a flat disc 2 and a disc 1 recessed to form the compartments A, B. The discs are held together by hydraulic cylinders 10 fixed to disc 2 and having pistons 17 connected to disc 1 by a frame 16 and posts 15. Hydraulic fluid is supplied through conduits 18, 19, 20, and when the supply is cut off springs 11 separate discs 1 and 2 to eject the material in the compartments. Truncated concentric cones 4, 5 communicate with the respective compartments to permit filling while the centrifuge is running. Each compartment has windows 6, 7 and a pair of photocells 8 and a ring of lamps is arranged above the windows 6. Deflocculation control. A stream of clay suspension to which has been added deflocculant is sampled and the sample split into two. Sufficient deflocculant is added to one portion to completely deflocculate it and the portions are fed to the centrifuge compartments. A self-balancing bridge circuit includes one of the cells 8 under each of the compartments. The other photocell under the completely deflocculated portion of the sample is a control photocell which varies the lamp brightness to maintain the light intensity on the photocells under the completely deflocculated portion substantially constant. After centrifuging for a time determined in accordance with the initial solids concentration by the control photocell, the position of the balance element of the bridge indicates the optical density ratio of the two sample portions which ratio depends on the deflocculation of the sample. The measured value is recorded and compared with a desired value to produce an error signal to drive a motor controlling the setting of a valve in the deflocculant supply to the main suspension stream. The centrifuge is then emptied and washed with water several times.
