Title: Method and system for controlling the temperature of vapour generated in a forced flow vapour generator
IPC: F22G5/00
Filed: 1963-10-31
Abstract: 1,061,197. Controlling steam temperature; forced flow steam boilers. COMBUSTION ENGINEERING Inc. Oct. 31, 1963 [Nov. 15, 1962], No. 43005/63. Heading F4A. In a method for controlling the temperature of vapour generated in a forced flow vapour generator operating at subcritical or supercritical pressure and having a number of subcircuits (14) each with tubes connected in parallel, the rate of flow of liquid to each subcircuit is initially adjusted so that the rate of heat absorption in each is substantially uniform, and the rate of heat absorption in each subcircuit then being sensed to obtain a mean overall rate and then being simultaneously controlled in response to the sensed mean rate. Line (30) supplies feedwater to header (22) which supplies headers (16) of each subcircuit and also header (34) of control tubes (32). One tube (32) accompanies each subcircuit (14). At the beginning of the process thermocouples sense the heat absorped in each subcircuit and valves (26) are adjusted to make this uniform. The line (42) leads from common outlet header (40) of the control tubes to an outlet header of the subcircuits and is also connected to a temperature sensing device (44) controlling a device which operates either feedwater valve (28) or fuel valve (50). Valve (38) is adjusted to ensure the superheating of steam in the final portions of tubes (32).

Title: Method for separation of conjugated Diolefin
Inventor: TAKAO SUSUMU
IPC: C07C11/16
Filed: 1966-09-27
Abstract: 1,161,683. Separating conjugated diolefins. JAPANESE GEON CO. Ltd. 27 Sept., 1966, No. 43050/66. Heading C5E. A process for the separation of a conjugated diolefin from C 4  or C 5  hydrocarbon mixture comprises introducing the hydrocarbon mixture to an intermediate portion of an extractive distillation zone through which a polar solvent is flowed downwardly, whereby a less readily soluble hydrocarbon fraction is formed as distillate at the top of the zone and a more readily soluble hydrocarbon fraction together with the solvent is recovered as liquid from the bottom of the zone; transferring the said liquid to a recovery zone operated at a lower pressure than the extractive distillation zone; returning an overhead vapour stream from the recovery zone to the extractive distillation zone; transfering liquid from the bottom of the recovery zone to a stripping zone; and recovering the more readily soluble hydrocarbon fraction as distillate from the top of the stripping zone while the solvent is withdrawn from the bottom of the stripping zone. The hydrocarbon mixture may contain hydrocarbons more readily soluble than the conjugated diolefin, hydrocarbons less readily soluble than the conjugated diolefin, or both. In the last case, a two-stage extractive distillation process may be used to recover the pure conjugated diolefin, a mixture of the conjugated diolefin and the more readily soluble hydrocarbons being obtained as the more readily soluble hydrocarbon fraction of the first stage, and this fraction being subjected to the process of the invention in a second stage to obtain the conjugated diolefin as the less readily soluble fraction. The polar solvent may be acetonitrile, furfural, N-methylpyrrolidone, butyrolactone, dimethyl formamide, acetone or a mixture thereof with water. The solvent may include polymerization inhibitors and/or chain-transfer agents such as furfural, aromatic nitro-compounds and benzaldehyde, and stabilizers such as sodium nitrite, methylene blue, sulphur, phenols or aromatic amines. The starting hydrocarbon mixture may be a C 4  or C5 fraction obtained by thermal cracking of petroleum, a C 4  fraction obtained by catalytic dehydrogenation of n-butane and/or n-butene or a C 5  fraction obtained by dehydrogenation of isopentane and/or isoamylene. Examples describe the separation of 1,3-butadiene from C 4  fractions containing paraffins, olefins and acetylenes. The process of the invention enables the bottom of the extractive distillation column to be at a relatively low temperature and thus decrease the tendency for the conjugated diolefin and/or higher acetylene to polymerize.

Title: Electrolytic method of manufacturing microwave components
IPC: C25D5/12
Filed: 1964-10-23
Abstract: Microwave components are made by electrodepositing on separate parts of electrically conductive components, e.g. of steel or Ni-Fe alloy, a flash of nickel for corrosion prevention, followed by a flash of silver for increasing conductivity, and brazing the parts together in a protective gas with a silver based solder such as of eutectic Cu-Ag alloy.  Prior to electroplating the components may be degreased by etching with HCl or a solution containing FeCl3, KClO3 and HCl (for Ni-Fe alloy). Individual parts, e.g. flanges at the ends of the waveguides, may be assembled into subgroups prior to electroplating by silver soldering.  At points where the silver solder is supposed to flow, a layer of copper 1 - 3 microns thick may be electrodeposited. The nickel may be plated from a flat-finish Schering or Watt's bath; silver plating baths containing more than 100 g/1.  KCN may be used.

Abstract: 1,003,692. Liquid-forcing apparatus; regulating. SIDLER Ltd. Dec. 6, 1961 [Dec. 7, 1960], No. 43781/61. Divided out of 1,003,691. Headings FIB and F1R. [Also in Division B7] A hydraulic device 16 for insertion between a pump 165 and the ram 2 of a car parking apparatus has a small area piston 35 which is movable by fluid pressure supplied to an inlet 23 connected to the pump to move a large area piston 33 which displaces fluid through an outlet 22 to effect rapid extension of the ram 2, the movement of the small area piston at the end of its stroke operating valve means 30, 31 to connect the inlet 23 to the outlet 22 and disconnect the large area piston from the outlet. The small piston 35 is guided on tubes 21, 24, tube 21 at one end being connected to the outlet 22 and formed with holes 30, 31, and at the other end being provided with a non-return valve 29 urged to a closed position by a spring 29d. When the pistons are moved to the right against a spring 32 by the fluid pressure from the pump 165 supplied to the inlet 23 under the control of a valve 166, such as described in Specification 852,124, the liquid displaced by the large piston passes through the holes 30, 31 to the outlet 22 to rapidly extend the ram 2. At the end of the movement to the right, the small piston closes the holes 31 and bears against a seal 34, and fluid from the inlet 23 then passes through the holes 30 to the outlet so that fluid at the pressure of the pump acts on the ram 2 which presses a roller 6 into engagement with the ground and a wheel of the vehicle to lift the wheel from the ground. When the valve 166 is operated to connect the inlet 23 to a reservoir, the pistons 33, 35 are moved to the left by the spring 32 and fluid displaced from the ram 2 as it contracts passes through the holes 30, 31 to fill the cylinder 16, any excess fluid opening the non-return valve 29 to pass through holes 36 to the reservoir. When a rod 171, Fig. 6, of the valve 166 supplying fluid to the ram to lower the roller 6 is moved, a cam 158 engages the slow running control screw 155 of the throttle to increase the speed of the tick-over of the engine and a stop 159 is moved into the path of the throttle control lever 154 to prevent the throttle being opened beyond a predetermined amount by means of the normal throttle linkage 152, 153. The Provisional Specification also describes the car parking apparatus which is described fully in Specification 1,004,872, and a telescopic ram which is described fully in Specification 1,003,691.
