Title: Improvements in or relating to operating means for control devices
Inventor: RICE HAROLD WILBUR
IPC: F16K31/06
Filed: 1952-03-13
Abstract: 712,354. Valves. ROBERTSHAW-FULTON CONTROLS CO. March 13, 1952, No. 6543/52. Class 135. [Also in Group XXXVII] Operating means for a control device, e.g. an electric switch or a valve 38 controlling the energy supply to an appliance comprises an actuating device for the control device, i.e the plunger 66 operated b) a clock, a temperature or pressure condition produced by a burner, or humidity; a safety device 14 for operating the control device in response to the presence or absence of an unsafe condition in the appliance, and a lever device 100, 102, 106 adjustable bodily to alternative locations on a support 16 for the devices, and engageable in both locations with the safety and control device, and in one location also with the actuating device, so that in the one location the lever actuates the control device only when both actuating and safety devices are operating, while in the other location the lever device engages the support and actuates the control device when the safety device operates, irrespective of the actuating device. On pushing rod 50, the armature 48 contacts an electromagnet 46 which when energized by a thermocouple heated by a pilot burner, holds the armature so that a rod 49 turns the lever 100 about the pivot 104 to bring the lever 102 pivoted at 114 on the lever 100 into a position where the plunger 66 can actuate the valve. On loosening screws 110, a frame 106 carrying the pivot 104 of the lever 100 is lowered to bring the projection 116 into contact with the support 16 so that the safety device alone can pivot the lever 102 about the projection 16 to actuate the valve. In a modification the valve stem 42 projects through a hole in a flexible link having a cam which slides over the end of the stem when the armature is moved and places a solid part of the link in front of the stem end so that a forked lever actuated by the plunger 66 operates the valve. By unscrewing a bracket from the support 16 the lever may be shifted bodily to its second location where the bracket enters another lever hole to form its alternative pivot.

Title: Improvements in or relating to the production of liquid hydrocarbons suitable for use as motor spirit
IPC: C10L1/04
Filed: 1933-03-03
Abstract: Ethylene is condensed in the presence of a mixture of low-boiling liquid hydrocarbons rich in naphthenes, yielding a product suitable for use as motor spirit.  The condensation is effected at increased temperature and pressure, preferably in presence of a catalytic heavy metal oxide such as molybdenum oxide.  In an example the liquid hydrocarbons are obtained by the vapour phase hydrogenation of middle oils produced in the liquid phase hydrogenation of coal.  Any high-boiling constituents formed in the condensation process are recirculated to the vapour phase hydrogenation.

Title: Improvements in or relating to electrical resistances, resistance heaters and the like
IPC: H01C3/10
Filed: 1932-03-04
Abstract: 397,932. Grid resistances. EXPANDED METAL CO., Ltd., Burwood House, Caxton Street, WILLIAMS, E. T., 5, Meadway Close, Golder's Green, both in London, and MELSOM, S. W., 28, Lansdown Road, West Hartlepool. March 4, 1932, No. 6630. [Class 37.] A resistance element is constituted by meshwork or other openwork metal in the form of a split tubular girder. In the construction shown in elevation in Fig. 1 and in plan in Fig. 3, a sheet of expanded metal 1 having unex. panded ends 2, 3 is bent into tubular form leaving a split 6 parallel to the axis of the tube. The ends are drilled with holes 4, 5 for receiving mounting or connecting bolts. The tube may be of other section, such as circular, semicircular or triangular. The split 6 may be helical instead of parallel to the axis. The expanded metal is preferably arranged so that the longer dimension of the diamond mesh is at right-angles to the length of the element. The tubular elements may taper from one end to the other, to facilitate cooling when the elements are arranged vertically. Where a number of tapered elements are employed, they may be mounted so that alternate elements are reversely tapered. The tubular element, shown in Fig. 1, may be arched instead of straight. Several elements may be connected in series, for example, as shown in Fig. 11, in which three elements are clamped together by bolts 7 in insulating tubes 8. The elements are spaced by metal distance tubes 9 and are prevented from being flattened by metal tubes 10. Insulating washers 12 are provided where adjacent elements are not to be connected. Springs may be placed under the nuts 11 or between the elements and spacers. Instead of relying on the spacing tubes for carrying the current, the elements may be left with unexpanded ends which may be bolted, clamped', brazed, or welded together. A number of elements connected in series may be formed from a single sheet of expanded metal having unexpanded edges, as shown in Fig. 14. The sheet is cut from alternate edges along lines X which do not extend right across the sheet, and small triangular pieces TP, TP<1> are cut out. The strips of material between the cuts X are bent to form split tubular members with the splits on opposite sides of the plane of the sheet. The sheet is then bent about the lines Y so that the tubular members have their split faces all facing in the same direction, and the unexpanded portions between the elements are bent at Z to form connecting tags. The resistance elements may be formed of stainless steel, stalloy iron, ordinary iron, or high resistance material.

Title: Taper roller bearings
IPC: F16C19/36
Filed: 1946-03-04
Abstract: 648,532. Taper roller bearings. FRENKEL, M. S. March 4, 1946, No. 6639. [Class 12 (i)] To avoid skewing of the rollers in a taperroller bearing the rollers have contact with a bearing-ring flange only at their outer end and are of such form or construction that a plane normal to the roller axis and drawn through the centre of gravity of the roller lies nearer to the rotation axis of the complete bearing than a plane normal to the roller axis and drawn through the centre of gravity of the linearly extending contact region of the roller with the rotating race. Thus, as shown in Fig: 1, the taper roller 11 has at its inner end a projecting part 25 which has no contact with the races. The plane normal to the roller axis and drawn through the centre of gravity C of the roller is spaced inwardly. by an amount Lmc from the plane normal to the roller axis and drawn through the centre of gravity of the linearly extending contact region of the roller with the rotating race 12, this latter plane being situated midway of the effective length of the contact as denoted by the dimension H/2. Spacing of the planes through the respective centres of gravity as above specified may be effected by providing an appropriately situated groove 32 in the roller as shown in Fig. 4, or in the race, or the rollers may merely extend radially inwardly of the race. Alternatively the roller may comprise portions of different density such as oil-filled cavities to effect the required spacing of the two planes specified above, or the rollers may have cavities extending inwardly from the outer end. Where such a cavity is extended to provide a through passage this may be shaped as a convergent divergent nozzle and so provide a centrifugal pump action to circulate air thereby cooling the bearing. The rollers may be flanged at their outer end to engage a groove in the race, Fig. 7 (not shown). To ensure all the rollers taking their share in the load the cage may be 'fitted with spring-pressed rotating members engaging the outer ends of the rollers at the axis end point. An equation is given expressing Lmc in terms of the cone angles of the bearing and rollers, load and centrifugal force, and dimensions of the roller.

Title: Improvements in or relating to electric resistances
IPC: H01B1/00
Filed: 1932-03-05
Abstract: 387,150. Resistance coatings and deposits. BARON, H., 231, Strand, London.-(Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) March 5, 1932, No. 6730. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 7, 1932.] [Class 37.] A resistance comprises an insulating carrier having a resistance element consisting of a glazing in which is embedded a finely divided conductor or semi-conductor applied thereto in the form of a surface layer. An insulating material such as vitreous enamel is mixed with finely divided conducting material, such as metal, metal oxide, metalloid, carbon, or carbonaceous material, and water and is sprayed or otherwise applied to the carrier body. After drying the film the resistance is baked, preferably at more than 700‹ C. if vitreous enamel is employed. The ohmic value of the resistance may be adjusted by varying the percentage of conducting or semi-conducting material. In a modification a carrier body of steatite, porcelain, &c. is coated with an easily fusible surface layer such as glaze or enamel. A resistance layer of finely divided conducting or semi-conducting particles is then applied, e.g. by cathode disintegration or separation from a gaseous phase, and the resistance is heated to the softening point of the enamel layer so that the conducting particles are diffused therein. This heating may be effected during the deposition of the conducting particles, and may be carried out in an evacuated vessel or in one filled with a neutral gas. When iron oxide or other oxides are employed as the resistance material, the resistance may be baked at a temperature of 1000‹ C. or more. The resistance film may be coated with graphite at the connecting points, before mounting the connecting clips. The effective length of the resistance layer may be increased by cutting in spirals or other subdividing lines.

Filed: 1941-05-26
Abstract: 574,447. Gas turbines. HEPPNER, F. A.M. May 26, 1941, No. 6733. [Class 110 (iii)] In a contra-rotational gas turbine, as described in Specification 544,909, the blades of the compressor 10 and the turbine 16, between those carried by discs 12 on the shaft, are carried by a cylindrical drum 8 mounted on bearings as shown. The blades are of aerofoil section and their roots are secured in helical grooves. The blades of the compressor are of constant height but blade angle and pitch are increased towards the delivery end. The turbine blades increase in height towards the exhaust and blade angle and pitch may also vary. The last outer ring of blades 9a of the compressor are short so that a portion of the air is diverted by the wall 17 and enters the combustion chamber, formed between rotating walls 18, with fuel from the nozzles 20. Other air is diverted by a plate 25, rotating with the shaft, and passes through holes 27 to cool the turbine. The rotating combustion chamber is spanned by helical blades 19 which give an axial component to the gases. These blades are hollow and admit cooling air. Air enters the compressor between stationary blades 35 which give it a rotational component and the gases leave between blades 30 which secure an axial discharge. A starting motor has two oppositely - running rotors 33, 34 designed so as to give the correct speed ratio to the turbine rotors. Heating or sparking plugs may be provided for starting and the brushes of the ignition gear are lifted automatically when the ignition circuit is opened.

Title: Improvements in and relating to thermionic amplifiers
IPC: H03G11/06
Filed: 1941-05-28
Abstract: 547,276. Frequency and phase modulation; automatic volume control. BRITISH THOMSONHOUSTON CO., Ltd. May 28, 1941, No. 6821. Convention date, May 29, 1940. [Class 40 (v)] An amplitude-limiting circuit, particularly intended for the removal of amplitude modulation in a frequency or phase modulated system, comprises an amplifying valve with self-biasing means in its grid circuit for maintaining the mean grid voltage beyond anode current cut-off, and with further means for varying the mutual conductance of the valve so as to maintain constant output amplitude. The input oscillations are applied to a tuned grid circuit 16, 17 and the output taken from a tuned anode circuit 20, 21. The input grid of the pentode valve 10 is biased by a grid resistance 18 and condenser 19, the resulting bias being dependent on the input amplitude and such that the input peaks just bring the grid to zero voltage. The resultings pulses of anode current are thus all of the same height, but diminish in width as the input amplitude rises. The oscillatory current in the circuit 20, 21 therefore tends to fall with a rise in input. This, however, is counteracted by a rise in the screen grid voltage, which occurs owing to the decreased voltage drop in the resistance 27 as the screen grid current falls. The condenser 28 byepasses the oscillatory frequency, but is not large enough to byepass the frequencies present in the modulation envelope.
