Title: Improvements in or relating to steam generators with tubular generating systems
IPC: F22B35/10
Filed: 1931-11-04
Abstract: 375,185. Fluid-actuated valves. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Nov. 4, 1931, No. 30537. Convention date, Nov. 12, 1930. [Class 135.] Valves controlled by pilot or relay valves.- The feed supply to the end of the boiler is controlled by a valve 15 operated by a servomotor 36 having a control valve 28, which is operated by the device 13, placed near an intermediate point where further feed is introduced. The further feed is similarly controlled by a valve 16 operated by a servomotor 37 having a control valve 29 operated by the device 14 placed in the steam outlet pipe 5. A rise in temperature of the steam in the pipe 5 increases the pressure of the fluid in the pipe 27 connecting the device 14 to the control valve 29, thus raising the valve against the downward pressure of a spring 41, and admitting pressure fluid through a pipe 35 to the servomotor 37. The consequent lifting of the feed valve 16 turns a lever 42 about its pivot 43, thereby moving a lever 44 pivoted to it downwards to compress the spring 41 and check the upward movement of the valve 29. At the same time, a link 46 moving upwards with the lever 42 raises a lever 47 connected by a rod 49 to a lever 50 restraining a spring 52 on the control valve 28, thus increasing the upward movement of the valve with consequent increase of the supply of pressure fluid through the pipe 34 to the servomotor of the feed valve 15. The lever 54 connected to the valve rod 38 is moved upwards to open the valve 15 upon a relatively large increase of boiler temperature, and the lever 44 on the spring 41 is moved downwards by a rod 55 connected to the levers 54, 44, thus moving the valve 29 to release the fluid pressure supply to the servomotor 37.

Filed: 1923-12-05
Abstract: 230,175. Thorp, F., and Parkinson & W. & B. Cowan, Ltd. Dec. 5, 1923. Gas-meters.-The passage of gas through a meter of the liquid-sealed oscillating bell type is cut off by a floatoperated valve if the liquid in the meter rises above a predetermined level. The valve may be attached to or be actuated by the usual floatoperated stop valve provided for closing the gas inlet to the meter if the liquid is below a predetermined level or a separate valve may be provided. The valve may close either against or in the direction of the flow of the incoming gas. An annular float surrounding the gas-inlet tube may be used. Fig. 3 shows a construction in which the stem b of the usual float-operated valve c carries a hollow cylindrical valve of the balanced type suitable for either direction of gas flow.

Title: Improvements in and relating to motion-transmitting connecting joints
IPC: B62D7/16
Filed: 1954-10-25
Abstract: 779,200. Hinges &c. THOMPSON PRODUCTS, Inc. Oct. 25, 1954 [July 6, 1954], No. 30629/54. Class 65 (2). A motion-transmitting joint, particularly for motor-vehicle steering-gear, comprises a flanged stud 42, rotatably supported in a housing 20 secured to one member, with a shank portion secured to the other member 12, the stud being supported in a thin-walled bearing member 41 of plastics material urged into good bearing engagement with the shank of the stud by a loaded resilient mounting in the housing. The material of the bearing member is preferably such as to need no lubrication, such as nylon or polytetrafluoroethylene. In the form shown the resilient mounting is an oil-resistant rubber ring 40 and the stud 42 and bearing member 41 have out-turned flanges pressed against the ring 40 by a dished plate 33 secured in the open end of the housing and engaging a domed end of the stud; any lateral movement of the stud in the housing causes the stud to be forced downwards, compressing the ring 40 and thus resisting the movement. In a modification Fig. 2 (not shown), the stud has a cylindrical portion above the flange, embraced by a bearing member and rubber ring similar to 41, 40, the latter ring being compressed by the cover 33, which is not in contact with the stud. The space between the cover 33 and the stud may be packed with lubricant. An oilresistant rubber washer 32 is provided between the parts 20, 12.

Abstract: 657,094. Two-way transmission. AUTOMATIC ELECTRIC LABORATORIES, Inc. Nov. 21, 1947, No. 30956. Convention date, Nov. 23, 1946. [Class 40 (iv)] In a two-way telephone system having a one-way amplifier for each direction, the lines are directly connected and the amplifiers disconnected if the anode current of a valve in either amplifier drops below a predetermined value. In the 22, repeater shown, the release of anode current relays 50, 92, by a reduction in the anode current of either amplifier, disconnects the amplifier from the line and provides a straight-through connection between the East and West terminals; the circuit change being effected by relays 1 and 4. The circuit can be tested locally by operating a key 100 which inserts an additional cathode resistance 48, 106 and short circuits the input transformers to prevent singing, and an alarm lamp 94 lit by the release of the anode current relays indicates amplifier failure. Manual gain control is provided by potentiometer 38 and feedback decreasing with frequency to effect additional equalization is provided by resistors 44 shunted by condenser 45 through a condenser 42 and resistor 43. E-W or W-E ringing is repeated from a local 90V 20# source by relays 2 and 3 operated by relays 5 and 6 respectively, the latter being operated by current from the source 93, when the triodes of the valve 77 are made conducting by incoming ringing.

Abstract: 310,179. Kidston, R. April 16, 1928. Grates.-Comprises a front grate of the type consisting of a lower part movable about pivots to occupy a vertical or inclined position, and an upper part or fall-bar hinged to it so that it may occupy a vertical or a horizontal position in either position of the lower grate, the visible stops being reduced to a minimum and slots in the side cheeks being avoided by the construction adopted. The lower part 5 has trunnions 6 pivoted in slots 7 in the side cheeks, and also a slot 8 in one or both ends co-operating with a quadrant. 9 on the side cheek. It is retained in the vertical position shown in Fig. 3 by contacting with the end of the quadrant, and is moved to the inclined position shown in Fig. 4 by raising it until the slot 8 passes over the quadrant. allowing the grate to be moved until it rests on stops 21.

Title: A process for the oxo synthesis of oxygenated hydrocarbon compounds and the resulting oxygenated hydrocarbon compounds
IPC: C07C29/16
Filed: 1950-12-22
Abstract: An Oxo synthesis is effected using as feed a crude mixture of alkenes containing dienes such as cracked paraffin wax-containing mineral oil residues, which mixture is first treated with sulphuric, naphthalene sulphonic or phosphoric acid, aluminium or zinc chloride, natural or synthetic clay, silica gel or bauxite to remove easily-polymerizable constituents until the content of alkyl-2-alkenes-1 is at most about 1 per cent.  A preferred feed mixture has a maleic anhydride value of 1-3 and a monoalkene content of more than 50 per cent.  The treatment generally leaves at least 75 per cent of the original mixture for use as feed.  The Oxo aldehydes produced yield alcohols which give good plasticizers.  In examples, a C6-C8 alkene fraction from the cracking of paraffin wax is treated for 15 minutes with 98 per cent sulphuric acid, the upper layer treated with 2 per cent caustic soda and distilled or the fraction subjected at various rates of throughout to the action of fuller's earth at 200 DEG  C. and 20 atmospheres. Reference has been directed by the Comptroller to Specification 684,958.
