Abstract: In a high pressure apparatus a pressure chamber 11, in which a mixture of gases or liquids is subjected to pressure and heat to alter them chemically, is formed by a tube 12 closed at its ends by a cylindrical member 13 and a cylindrical <PICT:0925976/III/1> <PICT:0925976/III/2> portion 16 of a two-part stamp 15 having a frusto-conical lower portion 17 and rigid metal or plastic gaskets 33 (see Group XXVI) are provided to seal off the gaps between the tube 12 and the member 13.  The tube 12 is laterally supported in a tube 20 surrounded by a pressure absorbing member 21 having conical surfaces 22, 23, 24 and cylindrical surfaces 25, 26.  Similar gaskets 34 are provided between tubes 12 and 20.  A mantle 27 is brought into contact with the surface 23 by a hydraulic press, to provide lateral support to the member 21.  The member 13 bears against a rigid piston 14 supported by a fixed disc 28.  The stamp 15 is surrounded by a rubber member 30 which is compressed to provide lateral support to the stamp when the latter is moved towards the pressure chamber 11 to generate pressure therein by a piston 18 actuated by a hydraulic press.  Alternatively, the piston 14 may be made movable and provided with a punch which is also forced in the pressure chamber.  The pistons 14, 18 are connected to an electric circuit to heat the chamber 11, insulating material 29, e.g. mica or paper, being placed around the parts 12, 13, 14.  The chamber 11 may be of cylindrical or parallelepipedic shape.  The parts 12, 13, 15 and a cylindrical portion 19 of the piston 18 may be cemented carbide and the parts 14, 18, 20, 21, 27 of steel.

Title: Metal target detection system

Filed: 1975-10-24
Abstract: 1493659 Radar MOTOROLA Inc 24 Oct 1975 [2 Dec 1974] 43843/75 Heading H4D It is stated that metallic objects (e.g. tank 2, Fig. 1) contain imperfections (e.g. gaps between plates 6) which act as virtual non-linear diodes 4 and so cause a harmonic to be radiated when radio radiation is incident on the object as well as the much stronger standard echo. Since the background will give an echo at the same frequency as the standard echo, the harmonic can be used to detect the object. To overcome the very low relative intensity of the harmonic, the radiation from the transmitter 11 is in the form of a frequency swept CHIRP pulse, the receiver 14 being selective to the harmonic of the CHIRP pulse and carrying out a pulse compression process.

The roller 22 is locked against vibration by a bearing 26 which co-operates with a mount 36 on a frame 20, and further by means of a locking mechanism effective to lock the carriage 23 to the frame 19 (37, 38, 39, 41, 42, Figs. 5, 6, not shown) A micro switch (43) ensures that the roller cannot rotate until it is secured against vibration. During rotation of the mould a concrete feeder device 30 is moved a track 27 (Fig. 4) so that the concrete mixture may be deposited inside the mould. After retraction of the feeder device the mould is rotated until a pipe has been formed and consolidated within the mould. The hoists 17 then lift the mould off the roller 22, which is retracted, and lower it on to the trolley 12 below, which then moves the mould onwardly to an elevator 32 from where it is transferred to a steam curing chamber. Empty moulds are returned by a conveyer 33 and elevator 34 to the input end of the conveyer 14.

Abstract: 1,237,084. Drying soap powders. UNILEVER Ltd. 1 Oct., 1968 [2 Oct., 1967], No. 44844/67. Heading C5D. A process for the production of a soap powder comprises spraying an aqueous soap slurry through a gas so as to remove some water from the soap slurry and to form particles of the soap and subsequently removing further water from the soap particles by passing a heated gas through a fluidized bed of the particles. The drying gas passed through the fluidized bed of particles is preferably heated to a temperature of at least 50‹ C., particularly 100-150‹ C. The gas in the first or second drying stages may be air or a mixture of air and a gas obtained by combustion of a flammable material, e.g. oil or coal gas. Both drying stages may be carried out in a single apparatus, but it is preferred that the two drying stages should be carried out in separate apparatus and that a different gas be used for each stage. The term soap is used to denote both pure soap and soap compositions comprising -in addition to soap conventional additives to soap powders such as surface active materials, specifically tallow ethanolamide and alcohol-ethylene oxide adducts; builders such as alkali metal silicates, sodium tripolyphosphate, magnesium sulphate, and the tetrasodium salt of E.D.T.A.; bleaching agents such as sodium perborate; sodium carboxymethylcellulose; sodium toluene sulphonate; and fluorescent agents.
