Title: Process for the production of internally plasticised epoxy resins
IPC: C08G59/42
Filed: 1967-05-19
Abstract: Internally plasticized resins are prepared by reacting a compound containing more than one epoxy group per molecule with a mixture of polybasic carboxylic acid anhydrides, at least a part of which (e.g. 5 to 50% by wt.) is a polybasic ether carboxylic acid anhydride; the latter may contain 1 to 3 ether oxygen atoms and 6 to 20 carbon atoms in the molecule. From 0.6 to 1.2 carboxylic acid anhydride groups may be present per epoxide group. Hardening may take place at 80-200 DEG C.ALSO:Ether carboxylic acids and their anhydrides are prepared by first saponifying a bis(b -cyanoethyl)ether of the corresponding diol by reaction with conc.  HCl with ice cooling followed by gradual heating up to 100 DEG  C. over several hours.  Boiling with acetic anhydride yields the dibasic ether carboxylic acid anhydride. Examples relate to the preparation of the anhydrides of (1) HOOC(CH2)2O(CH2)2O(CH2)2COOH, <FORM:1115538/C2/1> <FORM:1115538/C2/2> and HOOC(CH2)2.O(CH2)6O(CH)2COOH. The starting matrials are the bis-(b -cyanoethyl ethers) of ethylene glycol, propylene glycol, butylene glycol and hexanediol-1,6 respectively.

Abstract: 913,481. Hydraulic transmission of power. CHIVARI, I. June 29, 1961 [June 30, 1960], No. 23540/61. Class 69 (2). [Also in Group XXVI] An infinitely - variable fluid trans - mission comprises a pump part and a motor part, at least one of which has a rotor 10 coupled to its shaft 28 and in which substantially radial slides 12 are mounted in fluid-tight manner, bear permanently against the cylindrical inner wall of a housing 1 and are connected together by a common pivot 14 at their inner ends, the axes of the pivot and rotor always being the same distance a apart and the variation in transmission being effected by angular displacement of the axes. The pump part and motor part may be of identical construction, the inlet and outlet ports of the pump part being connected to the outlet and inlet ports, respectively of the motor part. Only one of the parts is described. The pivot 14 for the vanes 12 is supported in bearings 15 on a stub shaft 13 secured to an end wall 19 of the housing, and the rotor 10 is supported on bearings 9 in eccentric rings 5 which, in turn, are supported on bearings 6 in the housing. In the position shown in Fig. 6, the rotor 10 is disposed close to the port 4 and on rotation of the rotor and slides, an equal amount of fluid is displaced from port 4 to port 3 as vice versa so that the torque transmitted is zero. When the eccentric rings are rotated 90 degrees by a worm-and-wheel mechanism or gearing 23 connected to a hand wheel 21, the rotor is moved to make the path between the rotor and housing above the rotor greater than that below so that fluid is displaced from port 4 to port 3, the rotation of the rotor being transmitted by gearing 26, 27 to the shaft 28. The slides are maintained in pressure-tight relationship with the rotor by metal pieces 32 mounted in arcuate or knife-edged members 29, 30 and urged by leaf-springs 34 into contact with the slides. Similar sealing arrangements maintain the outer ends of the slides in pressuretight relationship with the housing. The ports 3, 4 are shaped so as to widen out as they open into the chamber of the housing.

Abstract: 998,227. Springs. STABILUS, INDUSTRIE - UND HANDELSGESELLSCHAFT. June 14, 1963 [June 19, 1962], No. 23830/63. Heading F2S. A spring or damping device - lled with compressed gas comprises two, , -tight chambers and respective displacemen; means acting in the two chambers the effective surfaces of the displacement means being inversely proportional to the normal pressure prevailing in the chambers in which they act and the displacement forces acting in opposition so that the device always tends to return to an equilibrium position in which the normal pressures prevail. As shown in Fig. 1, a differential plunger 5 extends into pressure chambers 3, 4 and through a partition 2 and carries damper members 7, 8 provided with bleed orifices 7a, 8a respectively. For equilibrium to obtain the pressure within the chamber 3 acting on the area of the larger diameter plunger portion must equal the pressure within the chamber 4 acting upon the annular area formed by the reduction in the cross-section of the plunger 5. In a modification, Fig. 2, the displacement plunger 5 is of constant size and slides through a sleeve 11 which is slidable within the sleeve 2 and carries the damper member 8. In a further modification, Fig. 3, the pressure in a chamber 12 acts on the annular face of a chamber 13 slidable therein and is balanced by the pressure acting upon a sealing piston 17 in the chamber 13 on the side of a piston-rod 14.

Filed: 1976-06-09
Abstract: 1505602 Thermal insulation COMMISSARIAT A L'ENERGIE ATOMIQUE 9 June 1976 [16 June 1975] 23899/76 Heading F2X Heat-insulating panels 3, 4 each formed by a stack of wire-fabric or wire-mesh elements and separated by sheet-metal elements 5 are supported opposite a wall 1 to be protected, e.g. the vault roof of a fast nuclear reactor, by a device comprising two yokes 8, 17, the yoke 8 being rigidly fixed by means of a weld fillet 9 to the wall 1 and the yoke 17 being joined to a plate 6 bearing against the panels 3, 4. The yokes 8, 17 each carry a cross-pin 11, 16. As shown in Fig. 1, the two cross-pins 11, 16 are connected by a chain formed of links 14, 15. The yoke 17 comprises a threaded end-piece 18 co-operating with a nut 19 for clamping the plate 6 against the panels 3, 4. Once the nut 19 has been tightened in position, its annular shoulder 20 is welded at 21 to the plate 6. Finally, a protective cover 22 is welded to the plate 6 over the nut 19. In an alternative construction, Fig. 2, the plate 6 engages beneath the yoke 17 between it and the nut 19. The yoke 17 is fitted with a metallic seal 23 which co-operates with a sealing plate 29 resting on the plate 6 to ensure leaktightness at the point of penetration of the plate 6. The chain may be replaced by a cardan-joint cross-piece (24), (Fig. 3, not shown) having two ears (25, 26) which are welded to each other but extend in two relatively perpendicular planes. The ears have bores (27, 28) for mounting the cross-pins 11, 16 of the yokes 8, 17. Accordingly, whether a chain or cardan-joint cross-piece is used, the device has two degrees of freedom with respect to the wall 1 making it possible to remove any danger of faulty positioning at the time of assembly of the covering. Where a chain is employed, slight rotational displacement of the device about an axis at right-angles to the wall 1 is also permitted. In a further arrangement (not shown), the heat-insulating panels 3, 4 are mounted so as to be spaced at a given distance from the wall 1.

Hydrocarbons, cracking.-In a process of cracking oils employing plant similar to that described in Specification 274,763 comprising a cracking coil 16, digester drum 17, still 3, and dephlegmator 5, the crude oil is first injected into the still 3 through a pipe 32 where it is vaporized, the vapours are fractionated in the dephlegmator tower 5 and the condensate collecting at the bottom of the tower 5 is led through pipes 13, 14, 15<1> to the cracking coil 16 and digester 17, the cracked products being injected directly through a. pipe 37 into the tower 5 or alternatively through a pipe 37<1> into the still 3. The residual oil in the still is led off through a pipe 23<a> to storage or is passed to the cracking coil through a valve 23<1> and the pipes 14, 15<1>. An intermediate fraction may be collected in a pan 7 in the tower 5 and this fraction is led off to storage through a pipe 11<a> or returned to the still 3 by a pipe 12. The crude oil is stored in a tank 26 and is preheated by passing through a coil 8 and a heat exchanger 24 where it is heated either by the condensate from the tower 5 supplied through pipes 13, 14, 21, 23 or by the residual oil from the still supplied through pipes 23, 23<a>. The plant is adapted for cracking (1) a low grade stock tending to deposit carbon on cracking, e.g. Smackoven crude, in which case the crude oil is injected directly into the still 1 and only the condensate obtained in the tower 5 is passed through the cracking coil, the cracked products being injected into the still 1; (2) a feed stock, e.g. Panuco crude, which does not tend to deposit so much carbonaceous matter in which case the crude stock is also passed directly to the still 1 and the residual oil therefrom is passed through the valvo 23<1> to the cracking coil 16 and digester 17, the cracked products being injected' directly into the tower 5; (3) gas oil which is stripped in the still 1 under pressure, the residuum from the still being cracked as before and injected into the tower 5, where condensate is collected in the pan 7 and returned to the still through the pipe 12. The digester drum 17 may be in duplicate.

Title: Sulfurization process
Inventor: SHEPHERD GEORGE ROBERT LUX
IPC: C07C309/06
Filed: 1959-07-14
Abstract: Halogenated aliphatic hydrocarbons are sulphurised by a process comprising heating the halogenated hydrocarbon with an aqueous solution of an alkali metal or alkaline earth metal sulphite and an alkali metal or alkaline earth metal bisulphite at a temperature of 300 DEG -500 DEG F. for a period of time until heat is evolved from the reactants and thereafter until at least a portion of the halogen in the halo-hydrocarbon is replaced by sulphur, the amount of bisulphite in the aqueous solution being sufficient to provide an aqueous phase having a pH of 5-9.  Preferably reaction is effected in a closed vessel, suitably under a pressure of 50-500 p.s.i.g. Chloro- or bromo-hydrocarbons may be used, the preferred compounds being derived from aliphatic hydrocarbons of M.W. 100-500 and containing 1-5 chlorine atoms.  An induction period preceeds the exothermic sulphurisation reaction.  Examples describe the sulphurisation as above of 3-chloromethyl heptane, yielding a sulphurised product still containing 1.73% chlorine, and of various chlorinated or brominated hydrocarbons derived from aliphatic petroleum feed stocks of M.W. about 400, yielding products containing various amounts of sulphur and halogen.  It is stated that the products, which may be used in cutting oils, contain substantially no oxygen and that the sulphur may be in sulphide or polysulphide groupings.
