Title: Improvements in apparatus for the reception of wireless signals
IPC: H01G2/00
Filed: 1924-06-26
Abstract: 240,899. Lea, N., and Radio Communication Co., Ltd. June 26, 1924. Composite units.-An inter-valve coupling-device for use in wireless receiving apparatus comprises two resistances and a condenser built into a single unit. The resistance for connection to the plate circuit of a valve is wound on a tubular bobbin 1, the second or grid-leak resistance 2 is housed inside the bobbin, and the coupling condenser 17 is supported in the base 14. To reduce the inductance and self-capacity of the plate resistance, the wire is wound in sectional grooves, alternate grooves being wound in opposite directions. One end is soldered to a tag 16 clamped against a terminal screw 19 by a nut 18. The other end is soldered to a pin 7 projecting through an insulating-plate 15 to a metal plate 5 on which a terminal 12 is mounted. The grid resistance 2 is removably supported between a coiled spring 9 and a clip 10 pivoted on the screw 11 that holds the terminal 4. The spring 9 rests on a washer under the head of a screw 8, which holds the bobbin on the plate 15 and metal plate 6, the latter forming an electrical connection to the terminal 13. The terminal screws 12, 13 clamp the base 14 in position, and the condenser 17 is connected across these terminals. The axis of the terminals 3, 4 should preferably be at right-angles to the vertical plane containing the terminals 12. 13. A waterproof cover 20 encloses the bobbin 1.

Universal joints. - A universal joint, applicable for use at the ends of a motor-vehicle propeller shaft 14, comprises a substantially hemispherical member 8, secured to or integral with the shaft 14 and slidably engaging a hollow cylinder 1, which is bolted to a cap 2 having a socket 6 for the transmission shaft &c., the parts 2, 8 being coupled together by a helical spring 7. The spring 7 is of flat rectangular wire, so that it is torsionally stiff but axially and laterally flexible, and is screwed on to plates 9 having transverse tongues 10 to engage slots 11, 12 in the parts 2, 8. Oil may be introduced through a plugged orifice 15, and dirt excluded by a flexible sleeve 13. Where joints are provided at both ends of the shaft 14, the springs 7 are coiled in the same direction, in order to avoid axial displacement of the shaft 14 under torque.

Title: Improvements in and relating to the production of hydrocarbons
IPC: C07C5/367
Filed: 1940-10-28
Abstract: In the dehydrogenation to aromatic hydrocarbons of saturated cyclic hydrocarbons having at least one ring of six carbon atoms in mixtures containing also added hydrogen and one or more of the substances paraffin hydrocarbons, pentamethylene naphthenes, unsaturated hydrocarbons, sulphur, and sulphur compounds, in the presence of a catalyst comprising one or more of the metals platinum, palladium, rhodium, osmium, irridium, and ruthenium, supported on activated carbon, the dehydrogenation occurs in one or more stages in each of which the mixture is heated away from the catalyst and then contacted therewith at a temperature not higher than the upper limit imposed by deterioration of the catalyst under the conditions of the reaction, the catalyst receiving either no heat through the walls of the reaction vessel, or heat at a temperature not higher than such upper limit, and in at least one reaction stage the temperature of the mixture contacting the catalyst is not substantially lower than the upper limit.  In an example petrol made by hydrogenation of creosote, and hydrogen are subjected to a mildly hydrogenating catalyst of zinc oxide and nickel at 270 to 280 DEG  C. whereby sulphur &c. is converted to hydrogen sulphide which is absorbed by the catalyst, and then passed successively through six dehydrogenation converters preceded by heaters and using a platinium catalyst on coconut-shell charcoal, the mixture entering each catalyst bed at 300 DEG  C. but leaving it at a lower temperature owing to the endothermic nature of the dehydrogenation.  Specification 577,813 is referred to.

Abstract: 1376959 Welding by pressure and fusion CLARKE CHAPMAN Ltd 21 March 1973 [7 April 1972] 16101/72 Heading B3R In joining tubes to a member, tubular stubs are friction welded to the member and a tube is welded to each stub in end-to-end abutting relationship by external orbital welding, the stubs being long enough to be resiliently sprung apart to allow an orbital welding device to perform the orbital welding. A tube plate 10 having holes 12, 14, 16 terminating in cylindrical walls 18, 20, 22 is secured to a plate 23 on a base assembly 24 by bolts 26 in the hole 12 and other holes. A tubular stub 30 to be friction welded to the wall 20 is provided with slots in the outer end and these slots are engaged by dogs 44 on a head 40 rotatably driven and movable relatively to the base assembly by an hydraulic ram. A shaft 46 is fast with the head 40 and extends through the stub 30 and at its end remote from the head has a central bore 48 and three spaced slots in each of which is located a wedge-like dog 50. The inclined faces on the dogs are engaged by inclined faces 52 formed on a shaft 54 whose end engages the bore 48 which extends through bearings 60 in a tube 62 mounted in the bore 14. The shaft 54 carries at its end remote from the stub 30 a bearing ring 68 forming part of a thrust bearing mounted in a block 70, the block being secured to a rod 74 slidable in a fixed housing 72 and spring washers 78 being located in the housing between the block 70 and the end wall of the housing. The spring washers exert a load on the shaft 54 at the start of friction welding and allow displacement of the stub to the right during upsetting. After the stub has been friction welded the flash is removed and all the other stubs are similarly welded. The ends of the stubs containing the slots are removed and an orbital welding device is employed to externally weld tubes to the stubs, the stubs being sprung apart to allow mounting of the device. The stub is preferably vertical during welding, stubs of different lengths may be used and instead of using driving dogs 50 the shaft 46 is slit to provide resilient fingers engaging wedge faces on the shaft 54.
