Abstract: 1,019,062. Transistor random noise generator. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 4, 1962 [May 8, 1961], Nos. 16651/61 and 32557/61. Headings H3B and H3T. An electrical noise generating circuit comprises an avalanche transistor J1 biased so that the transistor operates in the avalanche mode under the control of the collector junction random noise peaks when the latter are above a threshold level. In the circuit shown in Fig. 3 the output, from the avalanche transistor generator J1, comprising random positive pulses, is fed to a bi-stable triggering circuit 11, the output at terminal 12 of which, Fig. 4(a) (not shown), is a series of pulses of constant amplitude but random mark/space ratio. In order to keep the mean pulse rate constant the differentiated output pulses from trigger circuit 11 are fed to monostable triggering circuit 14 which provides a series of negative-going pulses of constant amplitude and pulse length for applying to the base of avalanche transistor J1 By varying the time duration of circuit 14 by means of capacitor C3 and resistor R4 the mean pulse rate at terminal 12 can be varied.

Title: An improved process for the isomerization of paraffinic hydrocarbons
IPC: C07C5/27
Filed: 1941-12-30
Abstract: 553,920. Isomerising hydrocarbons. STANDARD OIL DEVELOPMENT CO. Dec. 30, 1941, No. 16763. Convention date, Dec. 31, 1940. [Class 2 (iii)] A straight chain paraffin containing at least five carbon atoms per molecule is isomerized in the presence of a previously unused aluminium halide and a promoter until the effluent from the reaction zone indicates substantial cracking imminent, then the same catalyst and promoter is used for isomerizing a different straight chain paraffin of lower molecular weight and containing four to six carbon atoms. Thus normal pentane is isomerized to isopentane in presence of aluminium chloride and hydrogen chloride for 0.75-2 hours at 110-75‹F. and the catalyst is transferred to another isomerization zone where butane is isomerized to isobutane at 150-175‹F., for 3¢-4 hours. Free hydrogen may be used to suppress the tendency to cracking.

Title: Means for producing very high pressures
IPC: B30B12/00
Filed: 1920-06-22
Abstract: 169,274. Parsons, Sir C. A. June 22, 1920. Testing p h y s i c a l qualities of materials. -Relates to a method of and means for producing very high instantaneous pressures, of the order of a quarter of a million tons to the square inch, consisting in suddenly collapsing a metal body containing an evacuated cavity, the metals employed, such as lead, tin, copper, aluminium, or mild steel, being sufficiently ductile to flow when heavy external pressure is applied. The method may be applied to investigating the effect of the high pressures obtained on solids, liquids, or gases contained in the evacuated space. In one method, a vacuous space 2 is formed in a metal bullet 1, Fig. 1, which is fired into a steel block 3 having an aperture 4 of approximately the same dimensions as the bullet. In an alternative arrangement, an explosive is employed to collapse a leather sphere 5 formed in two portions and provided with a cavity 6 which may be exhausted through an aperture 7 closed after evacuation by a plug 8. The contacting surfaces of the spherical halves are accurately faced and the edges welded or soldered together, thin paper, graphite, or other packing being interposed. In addition, a thin metal band 13 may be spun round the abutting faces. Supporting-pins 12 for the sphere are carried by a steel container 10, in the annular space 9 of which is packed the explosive, fuses or electric wires 11 being employed for firing the charge. The density of the explosive charge may be varied by mixing it with a powdered compressible substance such as coal dust, but preferably an air space round the surface of the sphere is provided by surrounding it with a uniform layer of felt, cork, or other compressible substance of low specific gravity. ,These air spaces may be dispensed with if the sphere is surrounded by a relatively thick layer of explosive backed by sand &c. instead of the container, the collapse of the sphere being effected by the force of the detonation only, which is effected simultaneously at several points.

Title: Improvement in aeroplane wings

Filed: 1937-06-18
Abstract: 554,855. Aeroplane wings. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. June 18, 1937, No. 16941. [Class 4] The upper surface of an aeroplane wing, where it is desired to mount a gun turret ,is given an approximately spherical curvature corresponding as closely as possible to the normal fore and aft contour of the wing at that place so that a rotating cupola comprising a segment of a sphere of similar curvature may be substituted for it without introducing any serious irregularity in the upper surface of the combined wing and cupola. Fig. 4 shows a transverse section of a wing in which, between the points G, G<SP>1</SP>, the upper surface is formed as a segment of a sphere having a centre O so that over the area enclosed both transverse and longitudinal sections of the upper surface are circular arcs. A revolving gun turret having the same shaped upper surface may therefore be substituted for this section without disturbing the airflow as the turret is rotated.

Title: Improvements relating to laminated tubular structures
IPC: F17C1/02

Abstract: 947,171. Producing metal articles etc.; bending and breaking metals; brazing. DORROLIVER Inc. May 16, 1960 [May 20, 1959; Sept. 28, 1959; Nov. 10, 1959], No. 17143/60. Headings B3A, B3E and B3R. [Also in Division F2] A method of making a tubular construction or vessel highly resistant against internal pressure comprises providing a mandrel and strip material, preferably metallic, of high tensile strength and extremely thin compared to the width thereof, helically winding the strip around the mandrel at a helix angle selected to effect an overlap between the strip windings sufficiently large to provide a plurality of thicknesses of the strip to constitute a selected composite wall thickness in the resulting tubular construction, with a stress distribution, whereby significantly greater stress is imposed upon the outer edge portion of the strip than upon the inner edge portion of the strip, concurrently with a corresponding stretch of the outer edge portion made possible by the thinness and the high tensile strength of the strip accommodating the desired degree of overlap, bonding the windings to one another at the helical interface between the overlapping portions of the strip, and removing the mandrel. As shown, an apertured end piece 14 and a domed end plate 16 of a pressure vessel are respectively formed with sleeve parts 17, 18 and are aligned coaxially with a mandrel having a diameter equal to the outer diameter of the parts 17, 18, this assembly being mounted in a winding device. The leading end of the high tensile steel strip 11 is secured to the part 17, wound helically and under tension along the mandrel, and secured to the part 18. A bonding agent is introduced between the successive laminations of strip, and successive layers of strip are wound in opposite directions and with increasing tensions. The mandrel is preferably of the collapsable kind to facilitate the removal thereof from the finished structure, but may be in the form of a sand core, or solid and of a meltable material. To provide longitudinal strength, the end pieces 14, 16 have U-shaped grooves 28, Fig. 5, formed therein and a high tensile wire 31 is wound in sinuous fashion around the mandrel before application of the strip. An increase in strength of the braze or bond between the successive laminations is obtained by adding to the brazing or bonding agent an abrasive such as carborundum of fine particle size not over 50% of the thickness of the laminations joined by the bond. The strip tensioning mechanism includes a drum 23 mounted on a spring-mounted support 24, part of the periphery of which is surrounded by a spring-mounted band brake 25, the springs 26, 27 working in opposite directions so that tension is applied to the strip engaged between the brake and drum.
