Title: Recovery and stabilisation of low-pressure polyolefines
IPC: C08F6/02
Filed: 1962-06-06
Abstract: Homo or co-polymers of ethylene and/or a -monoolefines are simultaneously recovered and stabilized by treating the homo- or copolymer, preferably at temperatures between 10 DEG  and 100 DEG C., with one or more mono- or dithioglycols which are able to form stable complexes with the metals of the catalyst systems being used, said mono- or di-thioglycol being of the general formula <FORM:0972807/C3/1> where R is a hydroxy or mercapto group and R1 is hydrogen, an alkyl, alkoxy, alkyl mercapto, hydroxyalkoxy, phenyl, benzyl or naphthyl group.  The catalyst employed comprises (a) a monovalent magnesium compound or (b) a metal of Group I to III of the Mendel<\>aeeff system, or a hydride or organic compound of such a metal, in combination with a Group IV to VI metal compound.  Lists of thioglycols are given and mixtures of them may be used with one another or with other known stabilizers such as metal stearates and amines.  Preferred polymers to be treated are those of ethylene, propylene and butene-1.  The treatment is applicable to dispersions of such polymers and in the case of copolymers, to solutions thereof, and may be carried out continuously or discontinuously. After treatment with the thioglycol colour complexes are usually formed which can be washed out with acidified water or with methanol or methanol-water mixtures and the remaining polymer may be subjected to steam treatment followed by drying in vacuo preferably between 60 and 80 DEG C.  In the examples the thioglycols used are monothioethylene glycol and 2-hydroxypropyl mercaptan.

Title: Pump priming mechanism
Inventor: HATHAWAY LAWRENCE
IPC: F04D9/06
Filed: 1951-09-19
Abstract: 698,377. Centrifugal pumps. TRINITY PUMPS, Ltd. Sept. 19, 1951, No. 21986/51. Class 110(i) [Also in Group XXIX] The control member or members of the priming mechanism of a centrifugal pump 10 are operated by a fluid motor under the control of a valve 32 which is responsive to the delivery. pressure of the pump and is adapted to connect a motor port 34 alternatively with a fluid supply port 35 or a fluid return port 36. As shown the delivery pressure of the pump 10 acts through a pipe 42 on a spring- loaded diaphragm 40 connected to a piston valve 32 controlling the connections between the ports 34, 35, 36. The fluid motor comprises a cylinder 43 containing a spring-loaded servopiston 44. In the case of a pump driven by an internal combustion engine the exhaust gases of which may be passed through an ejector such as 19 which exerts a suction effect to raise liquid to the level of the pump impeller, the piston 44 through a linkage 49, 26, 27 operates a valve 25 in a pipe 20 connecting the suction pipe 12 of the pump to the low pressure point 21 of the ejector and also operates a hinged valve 18 by which the gases from the exhaust manifold 16 may be passed directly to the exhaust pipe 17 or by-passed through the ejector 19. The pipe 20 is fitted with a water trap 22. Until the pump is primed, the valve 32 is in its raised position and the piston 44 maintains the valves 18, 25 in the positions shown so that a suction effect is exerted through the pipe 20 to prime the pump. When priming is completed, the pump delivery pressure causes the valve 32 to be depressed so that the piston 44 moves to close the valve 25 and open the valve 18. The diaphragm or diaphragms 40 may be replaced by a piston. Where a priming pump is employed, the valve 18 and the ejector 19 are omitted and the priming pump is connected to the pipe 20 so that it is cut off when the valve 25 is closed.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1934-07-27
Abstract: 441,880. Fluid-pressure brakes. TOMLINSON, A. V., 65, Victoria Street, Westminster.-(Compagnie des Freins Westinghouse ; Sevran, France) July 27, 1934, No. 22001. [Class 103 (i)] Release of fluid - pressure brakes is accelerated by temporarily maintaining an abnormal train pipe pressure controlled by a valve influenced by the pressure in a chamber which is brought to an abnormal pressure during brake application and restored to normal during brake release. The pressure in this chamber may be the pressure in a brake cylinder or may be train pipe pressure which is increased or decreased on brake application. The abnormal pressure is supplied by a feed valve 4 controlled by a valve 31 controlled by diaphragms 22-24. Chamber 21 below diaphragm 24 is always maintained at normal train pipe pressure by a reducing valve 29 and a pipe 28. Pressure fluid from the brake cylinder 8 supplied by the pipe 27 to the chamber 20 between the diaphragms 23, 24 opens the valve 31, which when the driver's valve is in running and release position vents chamber 10 through pipes 25, 16 and the driver's valve to the train pipe 5. The piston 9 and slide valve 14 of the valve 4 are raised by fluid from main reservoir 2 which passes through ports 34, 35 of the slide valve to the pipe 16 and the train pipe to produce a temporary abnormal pressure in the train pipe. The pressure in the brake cylinder 8 reduces towards atmospheric pressure and the pressure in the chamber 18 above the diaphragms, which is now connected to the train pipe, increases and causes the valve 31 eventually to reclose as also will the valve 14 owing to leakage through a restricted port 33 and the abnormal pressure will be dissipated throughout the train pipe. The train pipe pressure is maintained at its normal valve by the feed valve 4, fall due to leakage of train pipe pressure in the chamber 18 causing the valve 31 to open and bring about operation of the valve 4 to supply the train pipe from the main reservoir. The pressure fluid in the chamber 21 may be replaced by a spring.

Abstract: 1502688 Structural joints SCANOVATOR AB 22 May 1975 [5 June 1974] 22234/75 Heading F2M [Also in Divisions E1 and B3] A tubular structural member 1 is formed by folding a single piece of sheet material, e.g. metal such as steel or aluminium, to form a rectangular or other polygonal tube in each face of which there is formed a groove or grooves 2, at least one of the grooves having sides 4 which slope outwardly from a flat bottom, and the free lateral edges of the sheet being joined to close the cross-section of the member. Preferably, the edges are joined at the bottom of a groove, either by interfolding of the edges (Fig. 2, not shown) or by welding or adhesives applied to overlapping edge portions of the sheet (Fig. 3, not shown). In a structure formed from a number of such members, the members are connected by connecting pieces or clamps of various forms as shown in the remaining Figures of the drawings. Fig. 5 shows clamping bars 5 of U-shape which co-operate with similar bars (5<SP>1</SP>, Fig. 4, not shown) to clamp simultaneously the grooves of two adjacent aligned members 1, 1<SP>1</SP>. The bars 5 (5<SP>1</SP>) are perforated on the lines 7 so that they can be drawn together by bolts passed through the perforations and through holes in the bases of the grooves, the sides 6 of each bar 5 diverging at an angle slightly greater than that between the sides 4 of the grooves, while the sides 6<SP>1</SP> of each of the other bars (5<SP>1</SP>) diverge at an angle slightly less than that between the sides 4. Fig. 5 also shows angled bars 9 for connecting member 1 to a transverse tubular member 1<SP>11</SP>. Fig. 7 shows a one-piece sheet -metal connecting piece providing pairs of arms 10, 10<SP>1</SP> each having groove formations to engage in the grooves of two mutually transverse tubular members 1, 1<SP>11</SP> in which they are secured by screws or rivets. Figs. 8-18 (not shown) disclose various shapes of single plates, e.g. flat, triangular or bent, which are similarly secured by screws or rivets passed through holes in grooves in the plates and engaging holes in the grooves 2 in adjacent tubular members to connect them. The connecting plates may be of wrap-around form (Figs. 19, 20, not shown) and may be formed in a continuous strip (Fig. 18, not shown). The connecting plates in Fig. 21 each have a number of grooves for engaging tubular members 40, 40<SP>1</SP> each of which has a plurality of grooves in at least one of its faces.
