Title: Improvements in the manufacture and production of catalysts for the oxidation of hydrocarbons
IPC: B01J27/18
Filed: 1928-11-08
Abstract: 325,234. Johnson, J. Y., (I. G. Farben. industrie Akt.-Ges.). Nov. 8, 1928. Catalytic agents, preparation of.-Catalysts particularly for the oxidation of hydrocarbons are obtained by precipitating a slightly acidified solution of a neutral metallic salt by means of a solution of a salt of an oxygen-containing inorganic acid, to which sufficient alkali has been added to give a slight excess in the mixture. Examples are (1) a mixture of cerium, cadmium, and aluminium nitrates precipitated by means of alkali metal phosphate; (2) a mixture of iron and zinc nitrates precipitated by means of sodium tetraborate. The catalysts may be treated before or during use with small quantities of corrosive gases, such as halogens, hydrogen halides, nitrosyl chloride, &c.

[Class 7 (v)] [See also Groups XXXII, XXII, and XXV] A high-tension spring, particularly for use in engine starters, is formed from a strip of material such as spring steel, by bending the strip into a circular shape having a circumference larger than that of the finished spring and a uniform cross-section of greater thickness axially than transversely, then weaving the circular strip into a series of inner and outer curved loops, and finally bending one series of loops to project laterally of other loops so that the spring bears only at its looped ends on the surfaces co-operating therewith, in order to minimize friction. Figs. 2 and 3 show a spring in which the inner loop-ends 2-7 bear alternately against each of the co-operating surfaces shown in broken lines in Fig. 3, the outer loopends being entirely free, while in the construction shown in Fig. 5 the inner loop-ends bear on one surface and the outer loop-ends on the other. Fig. 1 shows an engine starter in which an armature shaft 13 supports a slidable roller-holder 9, cam 10, and cone 11, the spring 8 acting between the holder 9 and an end-nut 14 to absorb the shock developed when the cam 10 and cone 11 contact with the engine flywheel 12 and to compensate for wear of the parts.

Abstract: 522,779. Master control of motors. IGRANIC ELECTRIC CO.. Ltd., and TAYLOR, J. R. Nov. 11, 1938, No. 32855. [Class 38 (iii)] Sequentially operated accelerating contactors have their time delay varied according to the manner of operation of the motor, e.g., forward or reverse, or in series or parallel with another motor. The time delay is given by the discharge of condensers C1, C2 through restraining windings 1b, 2b of accelerating contactors as disclosed in Specification 518,391. The variation of time delay is obtained by opening or closing a contact X and thereby varying the initial charge on the condenser.

Title: Improvements relating to rivetting tools and the like
IPC: B21J15/20
Filed: 1936-12-05
Abstract: 486,920. Setting tubular rivets. HAWKER AIRCRAFT, Ltd., and BURGOINE, S. F. Dec. 5, 1936, No. 33426. [Class 43] [Also in Groups XXII and XXIX] A hand tool for setting solid or tubular rivets or for countersinking, pressing, punching or like operations comprises in combination a hand tool incorporating a hydraulic piston and cylinder device for actuating the movable tool, and a pedaloperated hydraulic pressure generator connected to the cylinder of the tool by a flexible pipeline. A tool for setting solid rivets comprises a C-shaped frame supporting a hydraulic cylinder, the piston rod of which constitutes the movable snap-supporting means. The tool is connected by flexible pipeline 13, Fig. 7, to a hydraulic pressure generator comprising a piston 101 working in a cylinder 98. The piston is actuated by a pedal 95 against the action of a spring. The quantity of oil or other fluid in the system is determined by the position of a piston 104 in an auxiliary cylinder 106, the initial spacing of the jaws thus being determined. A valve 108 is closed after adjustment of the piston 104. A tool for hollow or pop-riveting by a process wherein a mandrel is pulled through an abutment 39, Fig. 2, to set a tubular rivet is used in combination with a generator as above described, being connected thereto by flexible pipeline 13. The tool comprises an abutment 39, and a chuck 40, 41 for gripping the mandrel which passes through the abutment 39 and the hollow rivet: The part 40 of the chuck is movable integrally with the piston 29, the split gripping portion 41 which engages at its forward end a tapered portion 43 of the sleeve 40 being movable relatively thereto under the action of a spring 44. A pin 45 engages slots 46, 47 in the sleeves 40, 41 respectively, the action being such that the jaws 42 are tightened on the mandrel at the beginning of the operation and released therefrom at the end of the return stroke. In a modification the mandrel is gripped between teeth 63 on a lever 64, Fig. 3, and a surface 66 on an inverted U-shaped member 61 which is connected to the piston-rod by a link 62. The jaws are moved to grip the mandrel by a spring 67 but are released at the end of the return stroke when a projection 71 strikes an abutment 60 which supports the fixed tool. In a further modification, the cylinder 76, Fig. 4, is offset from the line of action of the tools, the piston-rod 79 acting through a lever 82 pivoted at 81 to the frame 80, which supports the stationary tool 85. The gripping jaw 86 is movable relatively to the sliding member 84 and is urged to closed position by a spring 92. Relative movement is limited by a pin 89 engaging in inclined slots 90.

An apparatus for washing curved sheets comprises a conveyer having a support to hold a curved sheet in a vertical position, vibratory washing elements disposed on fixed lines one on either side of the sheet, and means for moving the washing elements so that their vibratory faces are in operative association with the surfaces of the curved sheet. As shown, applied to the washing of curved glass windscreens, the windscreens S, supported on a conveyer 12, are moved through a container 11 filled with a detergent solution. A cart 25 mounted on rails transversely of the container has depending therefrom members 29 each carrying a plurality of ultrasonic washing elements 32 having vibrating faces 33. As the windscreen moves between the members 29 a cam 40 in co-operation with a rod 41 and a rack and pinion rotates the members 29 so that their surfaces are always parallel to the surfaces of the windscreen, and a rod 46 attached to a piston and cylinder moves the cart 25 transversely of the container to maintain the windscreen between the members 29. The elements 32 may vibrate with a frequency of 100 to 30,000 cycles per second and the liquid may be a solution of sodium lauryl sulphate, an acid, kerosene, sodium silicate, or liquids containing abrasive particles.
