Title: Process for refining crude wax
IPC: C10G73/00
Filed: 1950-03-29
Abstract: Crude wax in a finely divided, preferably approaching colloidal, condition, is suspended in an acid or alkaline oxidizing bleaching agent, which is allowed to act on the wax at a temperature below its melting point.  The temperature may be controlled by cooling as necessary.  Suitable bleaching agents are chromic acid in sulphuric acid and potassium permanganate in alkali.  The bleaching agent may be regenerated electrolytically, either by withdrawing the liquid from the reaction vessel or continuously in the reaction vessel itself.  If desired, the wax may be cooled before being finely divided.  The process is particularly applicable to the crude waxes obtained from turf. In an example 100 kg. of resin-free Montan wax is finely divided and added to a mixture of 800 kg. of 40 per cent sulphuric acid and 200 kg. of chromic acid.  The bleaching is carried out at 50-60 DEG C.  The bleached wax is washed with dilute sulphuric acid at 50-60 DEG C and then with water.

Abstract: 809,249. Vehicle power steering. SOC D'INVENTIONS AERONAUTIQUES ET' MECANIQUES S. I. A. M. March 18, 1955 [March 19, 1954], No. 8025/55. Class 79(5) In a vehicle steering mechanism a transmission assembly connecting the steering wheel 1 to the steerable wheels comprises a driving rotor 28, a coaxial driven rotor 33 drivingly connected to rotor 28 with limited play, hydraulic valve located in the rotor 33 and having yieldable abutment means engaging the rotor 28 which are prestressed to transmit force from the rotor 28 to the rotor 33 up to a predetermined value and then to yield, whereby the valve gear is operated at the predetermined value to cause a hydraulic motor to assist the steering. As shown the invention is applied to a vehicle steering mechanism comprising a linkage 7 ... 12 operated from the wheel 1 on a shaft 2. A hydraulic system comprises a reservoir 18, a pump 19, an unloader 21, a non-return valve 22, a buffer-accumulator 20, the valve gear within a casing 3 and the hydralic motor having plungers 16 secured to the vehicle frame at 17 and a member 15 connected to a pin 13 on the steering link 11, the accumulator 20 being connected by a conduit 23 to the valve gear, conduits 24, 25 between the valve gear and the ends of the hydraulic motor and a conduit 26 connecting the valve gear to the reservoir 18. The rotor 28 is carried by the shaft 2 and a shaft 5 gearconected to the link 7 carries the rotor 33. The rotor 33 carries spring urged rods 31, 32 abutting cheeks on the rotor 28 and maintaining a mechanical connection between the shafts 2, 5 up to the force predetermined by the spring 30 acting on the rods 31, 32. Axially displaced valve spindles 34, 35 carried by the rotor 33 abut the cheeks on the rotor 28, each valve spindle comprising an annular groove 37 communicating with an axial bore 38. The pump outlet is delivered through the conduit 23, a conduit 44 in the shaft 5 and a passage 45 to the bore housing the spindle in the block, a passage 40 in the rotor communicates with the respective conduits 24 or 25 and a passage 47 communicates with a space 27 in the valve gear connected by a passage 48 to the return conduit 26. In operation, with the manual torque on the shaft 2 below that corresponding to the predetermined force the valve spindles are positioned as shown in Figs. 3 and 4 to connect the ends of the hydraulic motor to the reservoir. Depression of one or other of the valves due to the manual torque on the shaft comprising the spring 30 causes the groove 37 and bore 38 to interconnect the pressure conduit 23, with the respective end of the hydraulic motor to give power steering. The pressure in the bore 38 tends to react on the valve spindle and the appropriate check on the rotor 28 to give the driver "feel". In a modification Fig. 6 (not shown) the rods 31, 32 and spring 30 are omitted and springs 36 on the valve spindles take over the function of the spring 30. Specification 679,346 [Group XXIX] is referred to. Reference has been directed by the Comptroller to Specification 747,214 [Group XXIX]

Abstract: 315,675. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 16, 1928. Addition to 270,040. Grant of Patent revoked. Catalytic agents, preparation of.-A concentrated non-alkaline silica sol of the kind described in the parent Specification which contains at least 9 grs. silica per 100 ccs. of liquid and is converted into a solid gel in the usual manner, is prepared by mixing the decomposable silicon compound and the decomposing agent in any order rapidly together or by flowing the two reagents together. Nitric acid of 65 per cent strength is mixed with ice whereby a temperature of about -21‹ C is obtained. The mixture is poured rapidly into an agitated mixture of concentrated sodium silicate and ice. The acid sol formed is poured into flat sheet metal containers and solidified by exposure to air or by a current of warm gas in a tunnel stove and is dried, washed and finally dried at 200-400‹ C. Alternatively, ice-cold solutions of waterglass and sulphuric acid are introduced simultaneously into a sol, prepared as above, and contained in a mixing vessel, and the mixture is continuously removed from the vessel by an overflow. When acids are used as the decomposing agents, salts of heavy metals may be added to obtain mixed gels which may be used as catalysts. An alkaline sol containing undecomposed silicon compounds prepared by the gradual addition of the decomposing agent is treated to form a non-alkaline sol by adding the remainder of the decomposing agent quickly.

Abstract: 1329931 Air cooled surface condensers KRAFTWERK UNION AG 23 Feb 1972 [24 Feb 1971] 8439/72 Heading F4S A surface condenser comprises a cooling tower 1 in which is concentrically arranged two groups at least of surface condensing elements, one group 3 being disposed at the periphery and at the base of the tower and a second group 6 lying within the tower. Means are provided to allow one group, e.g. the internal group 6 of elements to operate as a reflux condenser. As shown, the peripheral group 3 are so disposed that an incoming cooling air stream 4 passes across these elements whilst another incoming air stream 5 passes under the group 3 and is guided by baffles 15 across the element group 6. In normal operation (e.g. in summer) steam from a distributer 10 flows via conduits 11-14 to the upper ends of both element groups 3 and 6 and is condensed therein. Under adverse (e.g. winter) conditions a valve comprising a movable sleeve (7, Figs. 3, 4) within the distributer 10 is actuated to close the steam supply to element group 6 so that all the steam flows initially to element group 3. Uncondensed steam then passes via a conduit 16 from the lower end of element group 3 to the lower end of element group 6 which thus operates as a reflux condenser. It is stated that either one of the element groups 3 or 6 may be made to function as a reflux condenser whilst the other functions normally. The annular element groups may be disposed in zig-zag fashion as shown in Fig. 2.
