Title: Process and apparatus for cooling coke oven gas
IPC: B01D51/10
Filed: 1958-10-01
Abstract: 846,643. Cooling coke-oven gas. ALLIED CHEMICAL CORPORATION. Oct. 1, 1958 [Oct. 2, 1957], No. 31332/58. Class 55 (2). [Also in Group XIII] In a process of cooling coke-oven gas withdrawn from a collecting main and containing naphthalene in a non- saturating amount together with water vapour, tar, ammonia and light oils, the gas is passed in indirect countercurrent contact with a fluid cooling medium to cool it to a temperature between 105‹ and 140‹ F. thereby condensing water and tar and producing a gas still not saturated with naphthalene of the condensed water and tar are collected, cooled and sprayed in direct contact to cool the partially cooled gas to a final temperature between 90‹ and 100‹ F., the resultant gas being supersaturated with naphthalene and containing ammonia and light oils. In the apparatus shown hot cokeoven gas enters a primary cooler 2 through an inlet 1 and passes successively through passes 5a, 5b, 5c and 5d each containing tubes through which a cooling fluid, preferably water, is passed in a direction opposite to that in which the gas is passing. Water and tar condensing out collect in a sump 16 and are pumped through a cooler 19 and sprayed into the partially cooled gas leaving the pass 5d. The finally cooled gas leaves by an outlet 3 and excess condensate may be withdrawn from the sump 16 by line 25. The cooler 19 is supplied with cooling fluid which subsequently is supplied to the pass 5d of the primary cooler.

Abstract: 214,575. Weisbach, C. H. [Firm of]. April 17, 1923, [Convention date]. Tentering. - The endless chains used in machines for stretching and drying fabrics are cleaned while they are in the chain guides at those parts where dirt is apt to accumulate by directing periodically steam, air, gas, or liquid under pressure upon such parts. Cleansing-agent is fed through an inlet f to a rotary distributing- valve 2 having ports c, d, e adapted to allow fluid to pass through ports g, h to the cavities a, b in the chain where dirt accumulates. The valve 2 is operated by the tentering-chain through gearing 4, 5, 6 so that the fluid issues only when the ports a, b are facing the outlet orifices g, h. A gap is formed in the chain-guide through which the dirt falls to a receptacle 3. Solvent for dirt may be added to the cleansing-agent by providing a branch inlet above the inlet f. The periodic supply of cleansing-agent can be concontrolled by slide valves.

Abstract: 1278484 Polyolefin compositions TURNER BROS ASBESTOS CO Ltd 17 Sept 1970 [23 June 1969] 31550/69 Heading C3P [Also in Division Dl] Glass fibres or filaments are sized with an olefin having a molecular weight of 200 to 5000. Suitable type of olefin is polybutene which has the general formula  In such an olefin the isolated double bond is resistant to amidation. Thus adducts may be formed with such compounds as maleic anhydride to give polybutenyl maleic anhydride. The olefin may be applied to glass fibre as a solution or as an aqueous dispersion. Surfactants may be incorporated as a dispersion aid, for example the triethanol amine ester of oleic acid, phthalic glycerol alkyd resins and substituted 2,3-dihydroimidazoles. In addition to olefins, it is desirable to incorporate one or more organo-silicon coupling agents such as in the sizing composition. These organo-silicon compounds have readily hydrolysable groups R, such as halogen and alkoxy groups and an organic group attached to the silicon atom having 2 to 8 carbon atoms.

Abstract: 1,198,334. Electric meters. HONEYWELL Inc. July 3, 1968 [July 6, 1967], No.31744/68. Heading G1Q. The movement of a moving coil meter which is intended to operate with a non linear relation between the input signal to be measured and the output deflection, so as to use as much of the possible angle of deflection as possible, is provided with a damping coil at an angle to the signal coil adjusted to give uniform damping over the full deflection angle. The moving coil 38 is wound round supports 40, 42 which are held in suspension by taut filaments 16. A bridge piece 50 with arcuate edges 52 is fixed across the inside of the coil 38. A single turn damping coil 46 is mounted on this bridge piece may be rotated about a pivot 54 engaging the support 40. The bottom part of the coil has a re-entrant part 48 of highly resistive wire which may be partly removed to alter the coil resistance. The two coils 38, 46 are arranged in the rest position so that when the movement is energized the absolute values of the acute rest angles which they make with the magnetic field change in opposite directions. To adjust the system, a standard square wave is applied to the movement and the angle of the damping coil adjusted to just below minimum damping. Final adjustment is achieved by removing some of the coil resistance 48.

The lead-lag angle of a rotary wing aircraft rotor blade is controlled by an hydraulic transmission. In the Figure, the rotor head comprises a disc 22c, and two parallel spiders 22a, 22b, supporting five blades 25 on drag pivots 24. Each blade is cyclically pivoted about its drag axis by a telemotor system comprising a slave cylinder 29 and a master cylinder 36 connected between disc 22c and the rotary element 42 of a swash plate. Where there is an even number of blades, opposed slave cylinders are hydraulically connected to each other and to a master cylinder, one for each pair of slave cylinders. The rotary member of the swash plate may consist solely of arms, one for each master cylinder, each pivoted to the rotor shaft at one end and having at the other end a roller received in a groove in a non- rotary inclinable ring. The master cylinder can then be secured to the rotor shaft, and communicate with the slave cylinders through bores in the shaft and flexible pipes. The slave cylinders contain longitudinal grooves on their inner walls, or other restricted by-pass ducts, the flow through which tends to cause the piston path to be symmetrically located longitudinally of the cylinder (see Figs. 5-12 (not shown).

Title: Improvements relating to friction welding
Inventor: PADILLA JOHN ARTHUR
IPC: B23Q11/04
Filed: 1966-07-18
Abstract: 1,137,115. Welding by pressure. WELDING INSTITUTE. 12 July, 1967 [18 July, 1966], No. 32187/66. Heading B3R. In friction welding wherein two workpieces are relatively rotated under axial pressure a signal representative of the load on a transmission responsible for the relative rotation is used to control the axial force, in a sense such that for peak levels of the signal the axial force is less than it would be in the absence of such control, at least for the initial portion of the frictional heating cycle. A motor 1 rotates a first workpiece 2 in a chuck 3 and the second, non-rotating'workpiece 4 in a chuck 5 is pressed against the workpiece 2 by a piston 6 in an hydraulic cylinder 7. A torque meter 8 is connected to the stationary shaft and applies a torque signal to an amplifier 9 which receives a command signal from a preset device 10. The output of the amplifier, the difference between the torque and command signals, is applied to a further amplifier 11 whose output is applied to a solenoid in a servo valve 12 which acts through the direction selector valve 14 to control the pressure at port 13 in cylinder 7. The force level is controlled by adjusting the leakage from the supply line 15 through the servo valve. If the torque signal equals the control signal the valve is in a neutral balanced position to provide a controlled leakage. With no load on the transmission the servo valve is closed and as the load increases to and above the command level the leakage will be increased. The servo valve may be connected to control fluid flow at both ends of the cylinder. The control of the axial force is preferably continued for the major part of the heating cycle but is discontinued when upset pressure is applied during deceleration of the workpieces. The duration of the controlled period may be defined by a pressure switch or displacement switch and the final arrest of the rotating workpiece and application of upset pressure may be controlled by an automatic timer. If hydrostatic transmission is employed a pressure transducer instead of a torque meter is employed.
