Abstract: 506,816. Lamp reflectors. SALANI, E., and PASSARDI, V. Dec. 1, 1937, No. 28004/38. Divided out of and addition to 506, 653. [Class 75 (ii)] In a reflector as claimed in the parent Specification, the reflecting elements are so arranged relatively to the luminous source 11 and are of such widths that the angle b, d or f subtended between the rays reflected by the two edges of one element 22, 25 or 28 located on one side, either of a central element 20 or of a pair of central elements, is equal to the angle c, e or g, subtended between the rays reflected by the two edges of the corresponding clement 22<1>, 251, or 28<1> located on the other side of the central element or of the pair of central elements, but is smaller than the angle a subtended by the rays 21 reflected by the outer edges of the central element or of the pair of central elements. In the arrangement to produce uniform illumination shown in the Figure, the rays 23, 26, 29 leaving the inner edges of the strips on both sides of the central strip lie in planes parallel to the plane of symmetry of the whole reflector, and the rays 24, 27, 30 leaving their outer edges are, on each side of the plane of symmetry, parallel to the rays 21 leaving the edge of the central strip 20 on the same side. In another form, the reflecting strips are all of equal widths and are so arranged that on each side of the plane of symmetry the rays reflected at their outer edges are parallel. In a third form, the rays reflected at the inner'edges of the strips on one side of the central strip cross the corresponding rays of strips on the other side, and may be parallel to the rays reflected by the remote edge of the central strip. Such a reflector surrounds the light source through an angle of more than 180‹ in a transverse plane, and a recuperating reflector is correspondingly reduced in size. In a fourth form, two inclined central strips and side strips are arranged so that more light is directed towards the edges than towards the centre of the beam. The reflecting elements may in other forms be arranged asymmetrically. This subject-matter was disclosed in the parent Specification as open to inspection under Sect. 91.

Patent GB-659065-A (GB)
Title: Improved process for the supply of heat to a solid heat carrier
IPC: B01J8/32
Filed: 1947-10-20
Abstract: <PICT:0659065/III/1> A finely-divided solid heat carrier, e.g. sand or powdered coke, is heated by passing it downwardly through a heating chamber 120 having three zones X, Y, Z one above another, and by passing hot gases produced by combustion in the bottom zone Z upwardly through the three zones at a rate sufficient to maintain the heat carrier in the top zone X in a fluidized state, the central zone Y being of substantial height and occupying the entire cross-sectional area of the chamber and containing solid packing comprising static contiguous elements larger than the heat carrier elements so as to provide a multitude of narrow passages for the downward flow of the heat carrier.  The process affords means of cracking oils, and carbonizing shale, coal, lignite and heavy residues.  In the apparatus shown, when used for carbonization of coal, powdered coke supplied to the chamber 120 up to the level B is maintained in a fluidized state by air supplied under pressure through pipe 114, and is heated by its own partial combustion.  It then flows along pipe 102 to chamber 110, mixing with powdered coal from inlet 101.  A fluidized bed is maintained in chamber 110 by gas supplied through line 124.  Gases and vapours evolved by carbonization in chamber 110 pass out through cyclone separator 104 and pipe 103.  Particles of carbonized coal return to chamber 120 through pipe 128 for re-circulation.  Fresh fluidized solid is introduced to chamber 120 through line 113.  At low temperatures in chamber 120 or low rate of coke flow through pipe 102, flue gas or inert fluid are mixed with the air supplied through pipe 114. In a modification, sand, heated in a chamber similar to 120, and coal are supplied separately to the central zone of a carbonizing chamber, the two solids being fluidized by hot gas or steam.  The sand passes downwardly through a packed zone to a lower zone, from which it returns to the upper part of the heating chamber.  The coal, heated by the sand, carbonizes and rises.  Combustion of carbonaceous material adhering to the sand may be sufficient to heat the latter in the heating chamber.  The Specification as open to inspection under Sect. 91 states that catalyst may be introduced through line 113 to chamber 120, and comprises also the subject-matter of Specification 647,914, [Group XII].  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of articles of or containing rubber
Filed: 1933-10-12
Abstract: A process for the production of articles-gloves, tubes, insulated wires, &c.-of or containing rubber direct from an aqueous dispersion of rubber comprises subjecting the dispersion to local cooling at the surface where the rubber is to be formed so as to increase the viscosity of the dispersion in the vicinity of the surface.  A range of 8 DEG  C. to -80 DEG  C. is mentioned.  The surface may be chilled to a temperature low enough to freeze a deposit of an aqueous dispersion thereon, e.g. when employing a dispersion coagulable on freezing; alternatively or additionally, coagulation or further hardening can be effected subsequent to the withdrawal of the surface from the dispersion, in this case the coagulant being kept at a low temperature so as not to disturb the shape of the coagulum by melting it.  The following is given as an example of a latex composition coagulable on freezing:-To 153.1 gms. of latex containing 65.3 per cent solids were added with moderate mixing-an emulsion of 0.5 gm. heptene base (an accelerator) with 0.06 gm. ammonium laurate in 0.88 gm. water; 0.63 c.c. of 28 per cent ammonia with 1.133 gms. water; a paste of 4 gms. crimson antimony sulphide, 4 gms. precipitated sulphur and 0.5 gms. of 20 per cent aqueous ammonium laurate with 9 gms. water; 1.288 gms. sodium silicate; and a paste of 1 gm. zinc oxide and 0.04 gm. glue in 1.50 gms. water.  The forms may be cooled by continuous circulating systems.  Preferably there is used a latex composition having a high temperature coefficient of viscosity, so that small variations in temperature will make great differences in the amount deposited.  Thick sheets of rubber may be made by passing chilled belts on drums through latex composition.  An electrical conductor, preferably provided with a cotton covering, may be cooled with dry ice to approximately -20 DEG  C.  The article may be produced by several dippings, with intermediate coagulations, washings, drying and curings.  Vulcanized latex may be used. Threads, bands, tubes, &c. may be made by streaming an aqueous dispersion coagulable on freezing through a nozzle provided with hollow chambers through which cooling medium is circulated; preferably the dispersion is streamed into a coagulant maintained at a lower temperature than the dispersion.
