Abstract: 1,157,874. Laminates. CARBORUNDUM CO. 22 July, 1966 [5 Aug., 1965], No. 33033/66. Heading B5N. [Also in Division C1] Laminated carbon or graphite articles are produced by forming carbon or graphite fibres into a shape comprising layers thereof without using a binder, maintaining the shape at a pressure below atmospheric pressure, pressureimpregnating the shape with a carbonizable binder, curing the shape while under pressure, baking the shape in a non-oxidizing atmosphere and optionally graphitizing the shape at 2500- 2800‹ C. Repetition of the impregnating, curing and baking cycle a number of times with an optional final graphitization yields novel reinforced carbon or graphite articles of density not less than 1À4 g./cc. The fibres used may be in the form of yarn, tape, cloth, felt or wool, and can be stacked into layers or wrapped around mandrels to obtain laminated shapes. The binder may be a liquid polymer of furfuryl alcohol or mixture thereof with furfural, phenolic or ureacondensation products, epoxy resins, dextrose, or coal tar pitch. The curing may be performed at 125‹ C. with a pressure of at least 90 p.s.i. The baking may be performed in a protective atmosphere with gradual heating to 800‹ C. but in the third cycle of a multicycle process a temperature of 1500‹ C. is preferably employed.

Title: Improvements in or relating to indole derivatives
Inventor: GAIMSTER KENNETH
IPC: C07D209/42
Filed: 1955-11-18
Abstract: The invention comprises indoles of the formula as below, substituted in the benzene ring by one or more alkoxy, aryloxy or aralkoxy groups <FORM:0841524/IV(b)/1> where A is a saturated hydrocarbon residue of not more than 6 carbon atoms and R1 is an amino group mono-acylated with an aliphatic, aromatic or heterocyclic mono- or di-carboxylic acid. The compounds are made by hydrolysis of the esters, and if in the starting material R1 is phthalimido this is converted into phthaloylamino at the same time, e.g. by using alcoholic potash for the hydrolysis.  The products can be decarboxylated and hydrolysed to give 3-aminoalkyl-indoles, in which the substituent in the benzene ring can be converted into hydroxyl.  In examples: (1) ethyl 5-benzyloxy-3 - (b  - phthalimidoethyl) - indole - 2 - carboxylate is hydrolysed to 5-benzyloxy-3-b -(o-carboxybenzamido) - ethyl - indole - 2 - carboxylic acid, which on heating gives 5-benzyloxy-3 - (b  - phthalimidoethyl) - indole; treatment of this with hydrazine yields 5-benzyloxytryptamine (isolated as sulphate), which is hydrogenolysed to serotonine (isolated as the creatinine sulphate); (2) ethyl-4 : 5 : 6-trimethoxy - 3 - (b  - phthalimidoethyl) - indole - 2-carboxylate is hydrolysed to 4 : 5 : 6 - trimethoxy - 3 - b  - (o - carboxybenzamido) - ethylindole-2-carboxylic acid, heated to give 4 : 5 : 6-trimethoxy - 3 - (b  - phthalimidoethyl) - indole and converted to 4 : 5 : 6-trimethoxytryptamine (isolated as sulphate); (3) preparation as in (2) of 5-methoxy-3-b -(o-carboxybenzamido) - ethyl - indole - 2 - carboxylic acid, 5-methoxy - 3 - (b  - phthalimidoethyl) - indole and 5 - methoxy - tryptamine (isolated as sulphate); (4) preparation as in (1) of 6-benzyloxy - 3 - b  - (o - carboxybenzamido)-ethyl - indole - 2 - carboxylic acid, 6 - benzyloxy - 3 - (b  - phthalimidoethyl) - indole, 6 - benzyloxytryptamine (sulphate) and 6-hydroxytryptamine (creatinine sulphate).  The ester starting materials are made from the appropriate substituted aniline diazotized and reacted with an a -alkyl-acetoacetic ester.  Examples show the preparation of the ethyl 3 - (b  - phthalimidoethyl) - indole - 2 - carboxylates substituted in the benzene ring by 5-methoxy, 4 : 5 : 6-trimethoxy, 5-benzyloxy and 6-benzyloxy.

[Class 64 (i).] Relates to means for preventing milk or other liquid from boiling over. The milk &c. is contained in a vessel 23 provided with a float 24 having a finger 25 engaging the lower end of a spindle 26 sliding in guides in a tubular member 17 suspended from the end of an arm 1 and carrying wire arms 18, 19, having hooked ends by which the vessel is suspended. The spindle contacts with the end of a lever 15 formed with a catch 16 by which a weight slidable along a slot 9 is held. The member 1 and the lever are both pivoted at 2 to a part 3 turnable about a spindle disposed within a column 4 the base of which is fitted with feet 6, 7 adapted to rest on a grate &c. On the milk boiling, the float is raised causing the lever to be lifted releasing the catch 16 and allowing the weight to slide along the slot, thus depressing the arm 1 and raising the vessel. As the arm falls, a roller 13 meets and follows a curved guide 14 thus swinging the vessel away from the source of heat.

A tractor power lift mechanism in which the upper link 2 can be connected to a pivot 10 to operate a control rod 9 against the action of a spring 11 whereby a control valve is operated through a linkage 12 to produce draft control, incorporates means to provide a substantially constant transfer of weight from the implement to the tractor. For weight transfer the upper link 2 is connected to the tractor at 34 and a pressure fluid connection 21 is opened between a piston and cylinder 26, 24 operating on the end of the control rod 9 and a valve unit 22. When the manually operable piston 27 is in the position shown the cylinder 24 is in communication with the operating ram 3 and the source of fluid pressure through conduit 23 so that variations in pressure in the operating ram 3 are transmitted through piston 26 to operate the control rod 9 which, in turn, operates the control valve to adjust the supply of fluid to the ram to keep the pressure therein, and therefore the transfer of weight from implement to tractor, substantially constant. When being used for draft control the piston 27 is pushed in to block off the connection between the cylinder 24 and the operating ram 3.
