Title: Process for the separation of mixtures of fatty substances into constituents of different melting points
IPC: C07C29/74
Filed: 1974-04-05
Abstract: 1470825 Separation of fatty mixtures HENKEL & CIE GmbH 5 April 1974 [7 April 1973] 15207/74 Heading C5C [Also in Division C2] Mixtures of fatty substances are separated into components of different melting points by (a) partially or completely melting the mixture so that the temperature thereof lies above the intended separation temperature, (b) adding an aqueous non-surface active electrolyte solution to the molten mixture and evaporating a part of the water of the electrolyte by vacuum and intensively mixing until partial or complete crystallization of the higher melting fractions is obtained, (c) adding a wetting agent solution to disperse the liquid and solid fatty substances, (d) separating the dispersion at the intended separation temperature by centrifuge into an oily phase containing the lower melting fractions and an aqueous phase containing the crystallized higher melting fractions in dispersed form. The examples illustrate (i) the fractionation of palm kernel fat, (ii) separation of a mixture of oleyl and stearyl alcohols, (iii) separation of stearic acid, stearin and olefin from a split tallow and (iv) separation of C 12  fatty acid from beef tallow fatty acids. The electrolyte is preferably Na, Mg or Al sulphate.

Title: Improvements relating to pedal operated mechanisms
IPC: G05G5/26
Filed: 1933-05-27
Abstract: - 407,569. Controlling pedals for motor vehicles. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and CANSDALE, J. H., 40, Murray Road, Rugby. May 27, 1933, No. 15377. [Classes 79 (v) and 136 (ii).] In a pedal-operated mechanism including a pivoted element 1 which is angularly displaced by a primary or bodily movement of a pedal 3, means are provided, actuated by a rocking movement of the pedal independent of the primary movement, for applying a variable retarding torque to the pivoted element 1 whereby a desired resistance to primary pedal movement may be set up. When the resistance is sufficiently increased the member 1 may be held locked in any position. In the construction shown the element or arm 1 is fixed on a shaft 2 actuating the controller of a motor vehicle. The pedal 3 is pivoted at 4 to the arm 1 and is connected by a link 5 and arm 7 to a cam shaft 8 operating brake blocks 9 which act on a fixed drum 10. The brake blocks are normally held off by a light spring 13 acting against a stop 12 on the arm 1. When the pedal 3 is depressed bodily or released the arm 1 moves freely, but if the lower part of the pedal is depressed by the driver's heel, the pedal rotates about the shaft 4 and the brake is applied, thus opposing to any desired extent movement of the arm 1 and finally locking it if sufficient pressure is applied to the lower end of the pedal.

Abstract: 612,372. Treating leather. BRITISH LEATHER MANUFACTURERS' RESEARCH ASSOCIATION, and HOUGH, A. T. May 22,1946, No. 15561. [Class 76] Vegetable-tanned leather is treated before, during, or after tanning with an aqueous solution of an amino resin containing boric acid or a water soluble borate; alternatively the treatment may be with two solutions, one containing the resin and the other the boric acid or borate. Suitable amino resins are methylol ureas, methylol melamines, resins derived from toluene sulphonamide and formaldehyde, and polyamides. Hexamethylene tetramine, guanidine, and other nitrogenous bases may also be present. Excess tannins are precipitated, and the wearing qualities of the leather and its resistance to acid rot are improved.

Title: Improvement in fuel injection apparatus
IPC: F02M59/04
Filed: 1943-09-22
Abstract: 571,501. Fuel-injection pumps. BENDIX AVIATION CORPORATION. Sept. 22, 1943, No. 15570. Convention date, Sept. 22, 1942. [Class 102 (i)] In a fuel-injection pump, a film of lubricant is established, between the working surfaces of a plunger and cylinder by means of one or more grooves in the surface of the plunger provided with an escape passage independent of the passage, and dilution of the film by fuel is prevented by means of a circumferential relief channel in the cylinder bore between the film and the metering groove and having continuous direct connection with the fuel supply line. Additional relief channels may also be provided in the surface of the plunger. In the form shown, a shaft 42 drives a cam 36 in engagement with rollers 35 to reciprocate plungers 14 in cylinders 8. A metering groove 15 in each plunger cooperates with by-pass port 12 in each cylinder, and the plungers are adjusted angularly by sleeves 20 gearing with a central control gear 27 rotatable by a hollow shaft 28. The latter rotates around a stationary hollow spindle 30 connected to a supply of lubricating oil and formed with ducts 49 and an annular groove 48. This groove opens into passages 50 each of which is connected by an axial slot 51, a radial passage 52, a central passage 53, and radial ducts 56 to a pair of diametrically opposite helical lubricating grooves 55 in the surface of each plunger 14. Any air trapped in the lubricating passages may escape through a relatively small bleed hole 57 connecting one of the grooves 55 to an axial passage 58 leading to a fitting 59 with a removable cap 60. Fuel seeping down between the plunger and cylinder is'trapped in an annular relief groove 61 between the ducts 56 and the groove 15, the groove 61 being connected by passages 62, 63 to the fuel inlet 13 The application of the invention to a single cylinder pump is described and illustrated in the Specification.

[Class 70] In apparatus for vulcanizing endless bands particularly those of wedge-shaped cross-section, a series of belts are held in grooves on pulleys a, c, the latter of which is slidable under the action of a hydraulic cylinder h to produce tension on the belts, and the belts are pressed by an endless band j, passing round the pulley a and around a pulley l, tension being produced on the band by a hydraulic cylinder k. The pulley a is heated to vulcanization temperature and is rotated at such a speed that each section of the belt is completely vulcanized by a single passage round the pulley a. Instead of a single band j, a series of bands each entering one of the grooves in the pulley a may be used. Both of the pulleys a, c may be heated and the band l may pass round both of them, a tension device intermediate of the pulleys being used. The band j may not be endless but may be connected at each end with the pistons z, z<SP>1</SP>, Fig. 5, of hydraulic cylinders r. The pulleys a, c may be intermittently rotated, being held stationary during the vulcanization of a portion of the belt.
