Title: Improvements in or relating to directional radio aerial systems
Inventor: BARRETT HENRY ARTHUR JOHN
IPC: H01Q3/20
Filed: 1956-10-23
Abstract: 816,244. Aerials. DECCA RECORD CO. Ltd. Jan. 23, 1958 [Oct. 23, 1956], No. 32346/56. Class 40 (7). A directional aerial of the type in which the direction of the principal lobe of radiation is variable comprises a receiving or transmitting radiator, a lens, and at least one reflecting surface. In the embodiment illustrated in plan view in Fig. 1, a horn radiator 10 passes a beam through a lens 14, the beam being deflected to the lens by means of a flat reflecting surface 12. The beam centre is directed towards the reflector, this point of incidence lying on an axis 13 in the plane of the reflector about which the reflector is revolved or oscillated. The lens 14 is designed to have a focal surface 15 of spherical shape and the centre of this surface is arranged to lie on the axis 13. The horn is so positioned that, on revolution of the reflector, the image of the radiator, as seen from the lens, travels around the focal surface. In a second embodiment the reflecting surface lies at 45 degrees to the axis 13 and to the axis of the lens, the horn being placed on the axis 13. With the above embodiments the centre of the beam does not stay near the centre of the lens so that the lens may not be well illuminated over the whole scan. To overcome this difficulty the position of the radiator may be varied. Thus the direction of the beam issuing from the horn may be altered in synchronism with the revolution of the reflector by revolving or oscillating the horn about an axis lying in the plane of its mouth. Alternatively, the horn may be fixed and a second reflector, moved in correspondence with the first reflector, placed between the horn and the first reflector so that the effective direction of the radiation from the horn is altered, Fig. 4 (not shown). The lens as illustrated in Fig. 1 is of the Fresnel type.

Title: Preparation of catalyst particles
IPC: B01J37/02
Filed: 1955-11-15
Abstract: <PICT:0792645/III/1> Catalysts comprising a platinum group metal deposited on alumina, are made by submerging pre-formed shapes of absorptive alumina in a large quantity of water circulated through a bed of the alumina pieces, slowly adding a solution of the platinum group metal thereafter continuing to circulate the solution, and finally drying and calcining the impregnated alumina.  The alumina is preferably obtained by hydrolysing aluminium alcoholate, but gamma, alpha, or eta-alumina may be used, and may also contain up to 5 per cent of silica.  The alumina is shaped by spray-drying alumina gel, setting to spherical form in an immiscible fluid, or by pilling or extrusion with or without a lubricant.  A suitable apparatus comprises an impregnating vessel 10, connected at the base to a tube 12 and an airlift riser 13.  The pre-formed alumina shapes rest on a screen 11, and water is circulated by passing air through a nozzle 16, whereby water is forced up the riser and cross-over line 14 to the vessel 10.  In an example, alumina gel made by hydrolysing aluminium amylate and drying the sol at 250 DEG  F. is ground and mixed with water.  The mixture is extruded and broken into pellets. After heating at 1050 DEG  F., the pellets are loaded into the vessel 10 and immersed in water, circulating through the apparatus. Thereafter a 10 per cent solution of chlor-platinic acid is added over 1/2 hour, and the solution circulated for a further 1/2 hour. The pellets are then removed, dried, and calcined at 1000 DEG  F. for 4 hours, and subsequently treated with hydrogen at 800 DEG  F. to form the metal.  The pellets contain from 0.5 to 2 per cent of platinum. The inner core of the pellet is free from platinum which is concentrated on the outer layer.  A uniform distribution of metal throughout the body of the pellet is achieved by adding to the circulating solution, absorptive modifiers, e.g. acetic, tri-chloracetic, nitric or hydrochloric acid; aqua regia; aluminium or ammonium salts; phenols, chlorhydrin or sulphonic acids.  Examples are given illustrating the use of the catalyst for hydroforming naphtha.
