Abstract: 297,558. Smith, F. E., Desborough, A. P. H., Thomson, W. T., Reynolds, H. F., and Blair, E. W. Aug. 26, 1927. Nozzles for producing whirling and like sprays.-Two or more liquids are simultaneously mixed and sprayed by introducing under pressure two or mora streams of liquid into a whirl chamber situated in proximity to a nozzle through which the spray is delivered. In the form shown a tubular body a having one or more lateral branches b through which liquid may be introduced under pressure, has at its end a centrally perforated end wall c, with a saucer shaped depression d connected to a cylindrical orifice d<1>. Within the body a and close to its outer end is arranged a plug e having a whirl chamber f formed therein communicating by a tangential passage g with an annular space h between it and the outer wall, and also communicating by an axial passage i, with a tube k coaxial with the tube a and serving as a passage for a further stream of liquid to be mixed and sprayed. The apparatus is stated to be applicable for mixing and spraying alkaline or other solution with nitro-glycerine in the manufacture of nitroglycerine, or for the preparation of mixed acid in the manufacture of explosives and also for producing a homogeneous spray of two or more liquids, suspensions, emulsion, solution, &c.

Abstract: 917,157. Processing leather. STROJOSVIT NARODNI PODNIK. July 1, 1959 [July 3, 1958], No. 22532/59. Class 76. Plates which have been used for drying, by hot air, hides stuck to them by means of an adhesive are washed by means of. water which is supplied to a plate washing machine and to a plate soaking chamber, and which is obtained by recycling water from air reconditioning towers, with or without the addition of water recycled from the washing machine or from both the washing machine and the soaking chamber. In a preferred embodiment, the apparatus comprises a sprayer washing machine A and a soaking chamber B and a collecting vessel C. Hot air laden with moisture absorbed from the hides is circulated through towers D and is cooled down in the towers by means of sprayers 9 to which clean water is supplied from a distributing conduit 10. This preheated water is led via a conduit 8 to the collecting vessel C which is fitted with a differential overflow 11 and 11<SP>1</SP>, the automatic control of which is effected by conical sealing rings set in floats. Water from vessel C is discharged via a pipe 21 to the spray mechanism of machine A and chamber B from whence the water passes into tanks 5 and 3 respectively and then via a weir to tank C.

Title: Improvements in and relating to electro-magnetic induction apparatus

Filed: 1945-09-07
Abstract: 616,536. Making transformer cores. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 7, 1945, No. 23133. Convention date, Sept. 11, 1944. [Class 83 (ii)] [Also in Group XXXV] In making a laminated magnetic core member, a number of magnetic sheets are stacked, gripped at one end where their ends are suitably arranged, and then bent so that the stack takes the shape of part of the core. To form a U-shaped core member, strips with ends cut diagonally and having holes at each end, at different distances from the different ends are stacked in layers, the strips in each layer being reversed compared with those of adjacent layers, Fig. 5. The strips decrease in length from top to bottom so that when the stack is made U-shaped the ends come generally together. To bend the stack, a pin 19 is passed through the aligned holes at one end which is clamped between two mandrels 21, 22, Fig. 6, which are then rotated counter-clockwise on a shaft 23, the sheets being bent round mandrel 21 by their engaging a stop 24. A pin 25 is then pushed through the holes having centre line at the free end of the stack, and through mandrels 21, 22 and holes in the clamped end of the stacks to replace pin 19. Mandrel 26 is then clamped to hold the second end of the stack, which is annealed, alone or assembled with a similar core half, Fig. 8. After annealing, rivets 27 may replace pin 25 and the U-shaped parts are placed in pairs round a winding 7, Fig. 10. The diagonal butt-joints of adjacent layers may, Fig. 12 (not shown), or may not, Fig. 9 (not shown), cross. One of the U-shaped core parts may be made from strips of uniform length so that the general line of the joints is not perpendicular to the plane of the lamination, Fig. 14 (not shown). To increase the ease of assembly, one U-shaped part 2 may have plates 34 riveted to it to form guides for the other part 3, Fig. 13. Specification 621,675 is referred to.

Filed: 1958-07-18
Abstract: Hydrogen cyanide is produced by the interaction of a hydrocarbon, e.g. methane, and ammonia in the presence of a catalyst comprising (a) up to 5% by weight of the total catalyst of one or more of the platinum metals platinum, palladium, iridium, and rhodium, (b) one or more of the elements copper, nickel, aluminium, and silicon in a total amount of up to 100% atom based on the total platinum metal content, and (c) an oxygen, nitrogen, and/or carbon compound of magnesium, calcium, strontium, barium, boron, aluminium, or silicon. The catalyst may be in the form of fine or coarse granules or small rods, and may be employed in a fluidized bed or in a bed moving countercurrently to the interacting gases.  According to the example, a catalyst prepared by precipitating alumina from a solution of aluminium sulphate containing platinum and nickel sulphate, the total metal content being 5% and the atomic ratio of platinum to nickel being 4 to 1, was employed at 1150 DEG C. and a throughput of 1 mol. of ammonia and 1 mol. of methane per hour.

July 29, 1954 [Aug. 21, 1953], No. 23166/53 Class 40(7) An aerial system, Fig. 1, comprises first and second aerial elements 1, 2, the first element being situated at the focus of the second element and having an aperture much larger in one direction than the other, and the elements being such that the beam from element 1 is projected on to element 2 and has dimensions thereat substantially equal to those of element but with the shorter dimension of the beam less than that the larger dimension of element 1. The aerial elements may comprise lenses, lens 1 being a shielded lens at the end of a beam 3 as shown, or mirrors. Thus Fig 2 (not shown) illustrates an arrangement in which element 1 is a cheese-type unit facing into but offset from the reflection path of a cylindroparabolic mirror forming the second element. In place of the "cheese," other elements such as the "pill-box" or "foghorn," may be used. The aerial system has application as a wide-angle vertical scanner, this being effected by reciprocating element 1 up and down as indicated by the double headed arrows. Alternatively, a plurality lenses 1 may be stacked over above the others and switched in succession. Two separate elements 1 closely superimposed one above the other may be employed for a precision height finder using the "split" technique, Fig. 3 (not shown). Fig. 4 illustrates a modification arranged for azimuth scanning, element 2 being replaced by a ring lens 22 of section corresponding to element 2.
