Patent GB-567442-A (GB)
Title: Improvements relating to incandescent electric lamps
IPC: H01K3/06
Filed: 1943-07-23
Abstract: 567,442. Electric incandescent lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. July 23, 1943, No. 12036. [Class 39 (ii)] In an incandescent lamp of the kind comprising several individual filament sections arranged electrically in parallel between spaced metallic supports, a continuous length of filament is tightly lapped about the supports so that each part of the length bridging the supports forms a filament section and the tightness of the lapping avoids the necessity of welding the filament to the supports, except at its ends. The requisite distance between the lappings is maintained by spacers. Fig. 1 shows a filament 5 lapped about supports 2, 3, the intermediate portions of the filament being located by the turns of wire helices 4 previously applied to the supports and, if desired, further secured by metal stirrups 6 welded at their ends to the supports and extending along the length of the latter so as to embrace the turns of the filament. Instead of the helices 4, the filament turns may be located by refractory spacers threaded on the supports between the turns, which spacers may be so arranged that the filament sections are physically parallel. Fig. 2 shows constructions in which parallel spacing of the sections is obtained by wrapping the filament several times about each support before the next lapping between supports is made.

Patent GB-1599114-A (GB)
Title: Rotary seal
IPC: F16C33/78
Filed: 1978-03-29
Abstract: The invention is an improved rotary seal which is particularly well suited for protecting the bearing area in a conveyor idler roll. The seal has inner and outer annular members which normally rotate freely without contact relative to each other. The members have cooperative means to form a labyrinth effective to restrict the ingress of contaminant or the egress of lubricant to or from the bearing area. One of the members further includes an attached annular disc of resilient flexible material. When the lubricant pressure in the bearing area increases, such as when the bearing is being regreased, it forces the free edge of the disc into contact with the other member to form a barrier against the leakage of lubrication. When the lubricant pressure normalizes, the resilient disc recovers to its normal, noncontact position.

Title: Improvements in or relating to gas burners
IPC: B21D28/32
Filed: 1957-04-16
Abstract: 833,040. Making burners and non-circular pipes. JUNKERS & CO. G.m.b.H. April 16, 1957 [April 25, 1956], No. 12354/57. Class 83 (2). [Also in Group XI] A method of manufacturing grid-type burners for gas-heated water burners, having burner pipes arranged generally perpendicularly to a header pipe is characterized in that the portion or portions of each burner pipe projecting from the header pipe is or are initially cylindrical in shape when the burner pipe is inserted into the header pipe and is or are then deformed, before the holes are made, into an egg-shaped crosssection tapering at an acute angle in the half of the burner pipe in which the burner holes are to be formed whereby to increase the resistance to deformation of the burner pipe in the axial direction of the burner holes when formed. Holes for receiving burner pipes 11 are first drilled in a header pipe 10 so that the burner pipes are a force fit in the holes and no additional clamping is required during soldering. The upper half of the burner pipes are then formed with plane surfaces 19 tapering to a convex edge 20 by means of dies 12 and 13. The die 13 has semicircular depressions 14 for supporting the lower half of each burner pipe and the die 12 has triangular channels 18 for forming the plane surfaces 19 on the burner pipes. Both dies are recessed to clear the header pipe and the solder seams. Finally, the burner holes 22 are drilled. In a modification, instead of the plane surfaces 19, slightly arcuate surfaces are provided using a die profile 24 (Fig. 5) and the lower half of each burner pipe is given an elliptical shape.

Title: Catalytic apparatus
IPC: B01J8/04
Filed: 1928-04-27
Abstract: 306,442. Selden Co., (Assignees of Jaeger, A. O.). Feb. 20, 1928, [Convention date]. Catalytic apparatus.-Apparatus for catalytic gas reactions comprises a converter of the kind in which the reaction gas passes through double counter-current heat exchangers embedded in the catalyst, and means for recirculating all or a portion of the partly reacted gases issuing from the converter, preferably after removal of the reaction products and addition of further quantities of reacting gases, and optionally after adjustment of the temperature of the recirculated gas. Gaseous reaction products or diluents may be removed from the recirculated gas by venting preferably through a device for absorbing the valuable materials present. The proportion of gas recirculated may be automatically regulated by the temperature of the converter. Temperature equalizing elements such as metal rods or tubes containing liquids may be embedded in the catalyst. Fig. 22 shows a system suitable for the side-chain oxidation of toluol. This is vaporized in the chamber 80 by the passage of an oxidizing gas over it and the reaction mixture passes through the converter 1 and heat exchanger 81 to the condenser 85 where benzaldehyde and benzoic acid produced by the reaction are removed. Superfluous gas is vented through an absorber 92. The remaining gas, with an addition of oxygen from the pipe 93, is recirculated optionally through the heat exchanger 81 and vaporizer 80 to the converter. The invention is applicable to a great variety of reactions, such as sulphur dioxide oxidation, ammonia synthesis, ammonia oxidation, and organic oxidations, reductions, dehydrogenations, polymerizations, condensations, &c. In particular, the processes referred to in Specifications 300,968. 306,883 and 306,884 are enumerated. The subject-matter of Specification 283,887 is disclaimed. The Specification as open to inspection under Sect. 91 (3) (a) extends the invention to gascooled converters other than those having double counter-current cooling. For example, Fig. 10 (Cancelled) shows a system wherein the catalyst is retained between grids in an annular layer 139, in which temperature equalizers 55 are embedded. Fresh gas entering at 140 is mixed with recirculated gas from the pipe 53 before passing outwards through the catalyst. This subjectmatter does not appear in the Specification as accepted.

Filed: 1945-05-18
Abstract: 595,700. Plug cocks. AIRCRAFTINGS, Ltd., and COHEN, I. May 18, 1945, No. 12544. [Class 135] A rotary plug valve of the type wherein the plug is eased from its seat prior to opening and jammed thereon after closing by gearing, comprises a plug b, Figs. 1, 3, having on its larger end a projection h, which engages limit stops j, j<1> on the casing a, and diametrically opposite thereto a helically-toothed gear segment e which engages with a worm f. A spring n disposed beneath the small end of the plug acts through a ball o to lift the plug, and an adjusting screw m acting through a ball at the top of the casing serves to limit the lift. In operation, when the valve is in the fully-open position, the projection h is in engagement with the stop j and rotation of the worm to close the valve will move the projection towards the stop j which, when contacted, arrests the rotary movement of the plug in the fully-closed position. Further rotation of the arm imparts an axial thrust to the plug and jams it in its seat against the action of the spring. Initial rotation of the worm to open the valve removes the seating pressure, the spring then forces the plug from its seat whence further rotation of the worm will permit the opening of the valve. To prevent unintentional operation of the plug, e.g. by vibration, the worm spindle g may be formed with a square portion g<1> which fits a complementary hole in a conical bush r forced into a conical hole in the casing by a spring t. The bush is formed with notches r<1>, Fig. 4, which loosely engage tongues u<1> in a sleeve u secured to the hand wheel, the rotation of which in either direction causes a camming action between the notches and the tongues to release the coned surfaces for operation of the plug.
