Title: Improvements in or relating to the utilization of the seed oil of mallotus phillipinensis muell. arg. (kamala)
Inventor: AGGARWAL JOTI SARUP
IPC: C11C1/02
Filed: 1951-09-04
Abstract: An acid called a -kamlolenic acid is produced from the seed of Mallotus phillipinensis Muell. Ary (Kamala) by saponifying the seed oil, treating the soap obtained to liberate the mixed fatty acids therein and isolating the a -kamlolenic acid from the mixed fatty acids by treatment with any petroleum solvent fraction boiling between 30 DEG  and 300 DEG  C., in which it is mostly insoluble. The acid may be converted to the isomeric b -form on exposure, in the presence of an organic solvent if desired, to ultra-violet light. Iodine may be used as catalyst.  The formul  of the a - and b -acids are: OH-(CH2)2CH=CH-CH= CH(CH2)2CH=CH(CH2)7COOH and OH(CH2)3CH=CH-CH= CH-CH2-CH=CH(CH2)7COOH. On reduction both acids give di-, tetra- or the hexahydro-kamlolenic acids, the hexahydro derivative being identical with o -hydroxy stearic acid. These acids may also be obtained by the catalytic hydrogenation of the oil followed by saponification.  The hexahydro kamlolenic acid may be oxidized with potassium permanganate to give hexadecamethylene 1 : 16-dicarboxylic acid.  In the examples: (a) kamala seed oil is heated with caustic potash and the resultant soap dissolved in water; the free acids are liberated from the soap by reacting with dilute sulphuric acid; the acids are dissolved in ether and after separation from the ether solution are treated with petrol ether to give a precipitate of a -kamlolenic acid; (b) the a -kamlolenic acid prepared as in (a) is suspended in petrol ether and irradiated with ultra-violet light in the presence of iodine to give the b -acid; (c) a -kamlolenic acid prepared as in (a) is hydrogenated in the presence of a platinum catalyst to give hexahydrokamlolenic acid; the same acid is obtained when the b -acid prepared as in (b) is similarly hydrogenated.

Title: Improvements relating to indicating mechanism
IPC: G01G23/18
Filed: 1936-07-28
Abstract: 479,031. Electric signalling systems. AVERY, Ltd., W. & T., and BINNS, A. July 28, 1936, No. 20850. [Class 40 (i)] In indicating-mechanism, a secondary pointer is magnetically connected to an indicating pointer during the indicating movement and an electromagnetic device is then operated which breaks the magnetic connection and clutches the secondary pointer to a driving means which is simultaneously brought into operation, the driving means returning the secondary pointer to zero, registering or other mechanism being driven by the driving means during this return motion. The invention is shown applied to a weighing machine. A pointer 2 pivoted at 1 moves to indicate the weight. A permanent magnet 3 is attached to the pointer 2 and at this time attracts an armature 4 on a freely-pivoted secondary pointer 5 whereby the secondary pointer moves with the pointer 2. A switch is then closed, either manually or automatically by delayed-time action, to energize an electromagnet 13 which attracts an armature 12 connected by pins 10a passing slidably through a disc 11 and freely through a hole in the centre of the hub of the secondary pointer 5 to a clutch disc 10 which is thereby moved against a spring 14 to clamp the secondary pointer 5 to the disc 11 and break the magnetic connection between the pointer 5 and the main pointer 2. At the same time a motor 15 is energized to drive a shaft 8 through a friction coupling. The disc 11 is secured to the shaft 8 and this disc and the secondary pointer 5 are thus driven backwards until the end of the pointer 5 engages and opens spring contacts 24 to break the circuit of the motor and of the electromagnet 13. At the same time an electromagnet 22 is de-energized whereby a brake 23a is applied by spring pressure to the edge of the disc 11. The shaft 8 drives a counter 26 which thus totalizes the weighings. The movement of the shaft may be used to actuate a printing-mechanism.

Abstract: 793,715. Looped yarns; tensioning means. ALGEMENE KUNSTZIJDE UNIE N. V. July 26, 1955 [Oct. 4, 1954], No. 21630/55. Classes 120(2) and 120(3) A device for the manufacture of looped yarns composed of a number of filaments, comprises in combination a tube in one end of which a jet of gas debouches and the other end of which is open and in the wall of which a yarn supply opening is provided, a first yarn guiding roller for guiding a yarn to the yarn supply opening, a second yarn guiding roller for guiding a yarn discharged from the open end of the tube, both yarn guiding rollers being connected togther and being freely rotatable around a common axis and a braking mechanism for said rollers which mechanism is operated by movement of a yarn guide which is movable against the'action of a spring or weight. In the arrangement ' shown 1 designates a supply package containing yarn to be looped and the yarn 2 is led therefrom through guides 3, 4, 5 and 6 to and around a large pulley 7 of a two stepped coaxial pulley including a smaller pulley 8 and hence over a rod 14 into a notch 15 in a tube 16 through which a stream of gas under pressure is supplied. After leaving the tube 16 the yarn is subjected to forces resulting from the gas impinging against a baffle plate 17 which deflects the yarn radially over a guide 18 and under the guide 6 to the pulley 8. Yarn 2 runs from the pulley 8 round a guide 20 to a take up device 36. The guide 20 is formed at one end of a U-shaped piece of wire 29 the other leg of which is bent at right angles to the outside. This bent end 30 is supported by one of the flanges 31 of the pulley 7 and extends further into an eyelet (not shown) fixed to the lower end of a helical spring 32 the force of which can be adjusted by a screw 33. The centre portion of the U-shaped wire 29 is rotatably mounted in a tube 28 and the arrangement is such that the end 30 of the wire 29 bears on the flange 31 of the pulley 7 with a force which depends upon the force exercised by the springs 32 and upon the tension in the yarn 2 running under the guide 20. If the tension in the thread under the guide 20 increases the thread will tend to rotate the U-shaped wires 29 against the thrust of the spring 32 and will thus tend to reduce friction between the end 30 and the flange 31 and therefore the pulleys 7 and 8 will be less braked in their rotation. On reduction of the tension of the yarn on the guide 20 the converse action takes place resulting in an increase in the braking of the pulleys 7 and 8.

Abstract: 875,798. Treating sewage &c. ACTIVATED SLUDGE Ltd. July 7, 1958 [July 9, 1957], No. 21651/57. Class 111. [Also in Group VI] In treating sewage or industrial waste effluent by aeration prior to sedimentation, a body of the sewage or effluent is agitated in its lower region by jets of liquid, preferably water, and at the same time is gently aerated, whereby the separation of grease as scum is facilitated. The liquid and the air may be supplied through a common nozzle, one form of which is shown in Fig. 5. This comprises a water-jet 15 connected to a water main 12 and an air-jet 16 connected to an air main by a pipe 17. Another form of nozzle for supplying air and water is shown in Fig, 27, in which a Venturi tube 30 connected to a water main 31 has an air supply pipe 32 attached thereto, the air being drawn in through slots 33. Separate air and water jets may also be used, however, and Fig. 26 shows an arrangement of this kind in which a water jet 25 impinges on a deflector 26 having a central dome 29, air being supplied from a main 27 through lateral openings 28. The sewage or effluent may be treated in a tank in which the jets may direct the liquid longitudinally, transversely or diagonally. As shown, in Fig. 1, the tank 10 has combined air and water jets projecting laterally from a water main 12, air being supplied from a main 13 through a pipe 14. In Fig. 6, the combined jets are arranged on one side of the tank. In Fig. 12 the tank has oppositely directed jets 11 set in a ridge 10a at the base of the tank, and also has partitions 19 to provide an aeration zone 20 and quiescent zones 21. Fig. 15, shows a similar arrangement in which the jets are directed rowards the centre of the tank, and Fig. 21 shows a partitioned tank having separate air jets 22 and water jets 23. In all cases the water for the jets may be derived from the final effluent of the plant. An alternative arrangement is mentioned in which a mixture of air and water is churned into bubbles in a separate tank and the mixture is  supplied to jets in the treatment tank. Another gas, e.g. carbon dioxide, may be used instead of air.
