Title: Illumination landing system
Inventor: GERMESHAUSEN KENNETH JOSEPH
IPC: B64F1/20
Filed: 1960-09-22
Abstract: 908,432. Lighting systems for airfield runways. EDGERTON, GERMESHAUSEN & GRIER Inc. Sept. 22, 1960, No. 32669/60. Class 75 (4). [Also in Groups XXXVIII and XL (a)] In an aircraft visual landing system, at least one pair of light sources disposed respectively on either side of a runway are so arranged that an axis of maximum light intensity from each source lies substantially parallel with the edges of the runway and that for successively larger angles off the axis there is a rapidly decreasing light intensity. It is stated that with this system the light sources do not have to be reduced in intensity as an aeroplane approaches the runway since the intensity of the light along a line down the centre of the runway is substantially the same for all distances from the runway. By using two pairs of sources 2, 2<SP>1</SP> and 102, 102<SP>1</SP> (Fig. 1) and with the beam from each source slightly inclined to the horizontal, an inclined descent path C (Fig. 2) can be obtained in addition to the horizontal locating path referred to above. The light sources consist of a high pressure (¢ - 2 atmospheres), xenon filled discharge tube, the discharge path being “ inch long. A trigger electrode 7 (Fig. 4) is placed midway between the anode 3 and cathode 5 and is also at the focal point of a parabolic reflector 22. The focal length of the reflector is three inches and its overall dimension one foot. A suitable trigger circuit is described (Fig. 3, not shown) which causes the tube to flash once per second to give a beam of total intensity 36,000 candle power-seconds with a half-power beam width of about 3-5 degrees.

Title: Improvements in the manufacture of urea
IPC: C07C273/04
Filed: 1937-11-30
Abstract: In the synthetic manufacture of urea by heating under pressure ammonium carbamate, obtained by reaction of gaseous carbon dioxide with liquid ammonia in the presence of an inert liquid, there is first prepared, in a closed vessel, by means of residuary gaseous carbon dioxide and ammonia, both derived from a preceding operation, ammonium carbamate in suspension in an inert liquid not miscible with water, e.g. a mineral oil, and this ammonium carbamate suspension is passed under pressure, at the same time as fresh carbon dioxide and ammonia, the latter advantageously in excess, into a high-pressure urea-formation autoclave heated to 150-250 DEG  C., which is constructed of materials resistant to attack by the reaction mixture, e.g. tin-coated or lead-coated steel, nickel, aluminium or its alloys, or highchromium steels with or without nickel, cobalt, molybdenum, tungsten and silicon. The resulting mixture of inert liquid, residuary carbon dioxide and ammonia, urea and water may, after reduction of the pressure, be passed to the top of a fractionating column, heated at its base, preferably working under pressures of 4-12 atmospheres, from the top of which the ammonia and carbon dioxide leave whilst the urea solution and inert liquid collect at its base and are separated by difference of density.  The urea solution may be directly crystallized, or first purified, e.g. by filtration in the presence of active carbon, if necessary after oxidation of ferrous compounds by a current of air or oxygen, and, when nickel oxide is present in the form of an ammoniacal complex, after passing the solution over aluminium cuttings.  If desired, the separation of the inert liquid may be effected at the top of the autoclave before release of pressure, or at the top of the fractionating column after release, instead of at the base of the column.

Abstract: 777,331. Sewing-machines; fabrics formed by stitching together threads. VEB WIRKMASCHINENBAU LIMBACH - OBERFROHNA. Dec. 1, 1953, No. 33404/53. Class 112. [Also in Group VIII] Fabrics are formed from at least two layers of loose yarns, the yarns in each layer lying across those of another layer and across the longitudinal direction of the fabric and the layers being interconnected by a plurality of parallel seams. Additional yarns lying parallel to the seams may be provided between or above the layers, and adjacent seams may be interlinked to secure these yarns. In the form described, two layers of crossing yarns are formed from a single group of yarns laid zigzag fashion in a band of a width, measured along the length of the fabric, equal to the pitch of the zig-zag. Sewing-machines. The yarns are drawn from a series of bobbins 31, Fig. 15, through a breaking device 33 and over a rod 35, carried by a spring-loaded lever to act as a tensioning device, to a set of eyes 27 arranged longitudinally of the machine and mounted on a carriage 28 slidable transversely of the machine on rails 29. A pair of endless belts 42 carry hooks 46 which receive the yarns from the eyes 27, the yarns being depressed on to the hooks at each end of the travel of the carriage by feet 57 mounted on a linkage 53 on the carriage and actuated by engagement of rollers with fixed cams 60. As the belts 42 move forward, the yarns are thus laid in zig-zag fashion between them, forming two crossed layers, which are then secured together by passing over a row of hooked needles which engage threads presented by loopers above the yarn layers to form a series of parallel chain-stitch seams. Additional yarns may be laid above or between the yarn layers, parallel to the seams ; either the needles or the loopers may be vibrated laterally so that adjacent seams are inter-linked to secure these additional yarns. The belts 42 are spaced slightly further apart at the delivery end, so that the layers of yarn are tensioned as they are moved through the machine, and are tilted, as shown, so that the work is readily removed from their lower runs; means may be provided for twisting them further locally for this purpose. A needle for this machine is formed of a sheet metal strip 14, Fig. 4, bent upon itself to form a narrow channel in which a slider 8 (for closing the hook) rests on a filling piece 15 ; the point of the needle is offset to the side on which the hook is open, to avoid displacing the yarns, and is formed from an extension of one side of the part 14, which is joggled so that the point lies on the centre-line of the needle.
