Patent GB-799383-A (GB)
Title: Epoxyalkylsuccinic acid derivatives and the process of making them
Filed: 1956-07-18
Abstract: The invention comprises esters of epoxyalkyl-succinic acids having the formula <FORM:0799383/IV (b)/1> in which (CnH2n-1O) represents an epoxyalkyl group containing from 4 to 12 carbon atoms, and R1 and R2 each represent an alkyl, alkoxyalkyl, cycloalkyl, aryl, aralkyl, alkaryl, or heterocyclic group.  Preferred esters are those which contain similar or dissimilar R1 and R2 alkyl groups containing from 4 to 12 carbon atoms, the total number of carbon atoms in the R1 and R2 groups preferably being not less than 8.  The novel compounds may be prepared by reacting an alkenylsuccinic acid ester with peracetic acid free from water, mineral acids and hydrogen peroxide, preferably in an inert organic solvent such as acetone or ethyl acetate, at 10 DEG  to 140 DEG  C. and preferably at 25 DEG  to 75 DEG  C.  It is preferred to use a slight molar excess of peracetic acid.  After the reaction is complete, acetic acid, solvent and any excess peracetic acid are removed by distillation with ethylbenzene or other suitable azeotrope-forming agent and the epoxide ester is recovered by extraction, crystallization, precipitation or distillation.  Detailed examples describe the preparation of (1) dibutyl epoxydodecylsuccinate; (2) di - 2 - ethylhexyl epoxypentylsuccinate; (3) didecyl epoxybutylsuccinate; (4) di-2-ethylhexyl epoxyacetylsuccinate; (5) di-2-ethylhexyl epoxyheptylsuccinate; (6) and (7) di - 2 - ethylhexyl epoxyhexylsuccinate; (8) di - 2 - ethylhexyl epoxynonylsuccinate; (9) decyl 2-ethylhexyl epoxynonylsuccinate; (10) didecyl epoxyhexylsuccinate; (11) 2-ethylhexyl decyl epoxyoctylsuccinate. The unsaturated ester used in Example 9 is obtained by esterifying nonenylsuccinic anhydride with a mixture of 2-ethylhexanol and decanol to give a mixture of didecyl, 2-ethylhexyl decyl and di-2-ethylhexyl nonenylsuccinates and the epoxide derived therefrom is a mixture of three epoxide esters. Similarly, the starting material in Example 11 is obtained by esterifying octenylsuccinic anhydride with a mixture of 2-ethylhexanol and decanol to give a mixture of didecyl, 2-ethylhexyl decyl, and di-2-ethylhexyl octenylsuccinates.  The epoxy ester products are useful as plasticizers for vinyl-type resins and particularly the halogen-containing vinyl-type resins.

Title: Die cushion assembly
IPC: B29C43/00
Filed: 1962-06-08
Abstract: 943,072. Compression moulding machines. DANLY MACHINE SPECIALTIES Inc. June 8, 1962 [June 8, 1961], No. 22251/62. Heading B5A. A die cushion assembly consists of a cylinder and a hollow piston telescoped for relative movement and enclosing a space therebetween, the piston containing a reservoir of fluid under pressure which may be communicated to the space between the members by the actuation of a normally closed valve. Such a die cushion may be used in a press having a fixed lower die and a movable upper die. In a press (Fig. 1) knock-out pins 38 are supported on such a resilient cushion by rods 48 and plate 50. The cylinder 52 co-operates externally with the hollow piston 56 and is raised and lowered by fluid under pressure introduced into the space 70 through the valve 88, 84, Fig. 2, or 176, 172, Fig. 3. During the moulding operation the pins 38 are forced down against the pneumatic pressure, by the upper die, so that upon withdrawing the upper die the pins are raised, thus ejecting the moulded article. In the modification, shown in Fig. 2, the cylinder 52 is normally in its inoperative position, i.e. lowered, in which the valve 88, seated on the upper end of rod 90, is pressed against the aperture 84 by spring 104. The cylinder is raised to the operative position by introducing air under pressure into space 106 and into the space between the piston 112, seated on the lower end of the rod 90, and the fixed cylinder 108. As the piston 112 is of greater area than valve 88, the valve is withdrawn from the aperture so that air under pressure enters the space 70. The upper valve may be closed, by the spring 104, by-releasing the pressure in the lower cylinder and the cushion lowered by releasing the pressure in the space 70 by means of valve 162. To raise the cushion again, the valve 162 is closed and air readmitted to the cylinder 108. In a second modification, Fig. 3, the valve 176, which is adapted to form a restrictive passage between itself and the valve seat 172 when withdrawn slightly, is opened by direct pressure of the compressed air in space 106 upon the upper surface of piston 188. To lower the cushion the upper valve is closed, by equalizing the pressures on both sides of the piston 188 by admitting air under pressure into the space below the piston, and the pressure in space 70 is released through valve 212. The cushion is raised again by introducing compressed air at a slightly reduced pressure, through supply line 222, to the space 70 and at the same time opening the valve 176. By controlling the rate at which the pressure is released from the space below piston 188, by throttle valve 206, the rate of withdrawal of the valve 176 may be controlled and thus the pressure within the space 70 may be built up slowly. The upper valve opens fully only when the cushion has reached the operative position which prevents any undue shock caused by ring 72 and shoulder 74 coming into fierce abutment.

Abstract: 1,079,627. Pointing tubes. BLAW-KNOX CO. May 23, 1966 [June 28, 1965], No. 22796/66. Heading B3P. Tube-pointing apparatus comprises six equi-angularly spaced jaws 30, the inwardly-directed edges of which are V-shaped and which are forced radially inwards by an hydraulicallyoperated piston 45. Portions 83 of the edges of the jaws are cut away to leave sharp-edged projections 77 which indent the tube. Continued inward movement of the jaws then folds the tube inwardly until adjacent wall portions are touching, Fig. 4. To enable the apparatus to point small diameter tubes, Fig. 11, the jaws are relieved at 82 on either side of the apex. The jaws are mounted in a frame including a cylinder 10 which is closed at its front and rear ends by cylinder heads 18 and 22 respectively. The rear end 14 of the cylinder bore is larger than the front end 16 which is itself larger than the intermediate portion 15. A piston 45 slides in the bore 14 and has an extension 49 which slides in the portion 15. The extension 49 has radial T-slots which accommodate the jaws 30 and a wear-strip 36 which is attached to each jaw. The wear-strips are wider than the jaws and slide in the head of the T-slot so that the jaws are moved positively inwards and outwards as the piston moves forwards and backwards respectively. The rearward movement of the piston is stopped by the flanged end 66 of a manually adjustable screw 66, so that the jaws open to a pre-determined diameter at which the projections 77 just engage the tube. Hydraulic fluid is admitted through a conduit 55 to drive the piston forward and when the pressure in the system builds up at the end of the operation, the conduit 55 is connected to exhaust and fluid admitted through the conduit 56 to return the piston. At the end of the return stroke the increase in pressure stops the apparatus.
