Abstract: 923,692. Hydraulic apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 9, 1961 [Jan. 14, 1960], No. 1353/60. Class 69 (2). A device for metering or controlling the rate of flow of a liquid comprises an outer body with inlet and outlet ports and an inner member which is reciprocable or rotatable to bring a measuring chamber from a filling position at the inlet port to a discharge position at the outlet port. In the reciprocating version shown, the body 1 is embraced by a pair of solenoids 14, 15 and the inner member 4 has a pair of soft iron armatures 16, or ceramic or steel magnets, so that by alternate energization and de-energization of the solenoids at a desired rate the chamber 5 is filled at the inlet port 2, moved over the outlet 3 and then back again to give a controlled rate of flow. Gas pressure is introduced through a port 10 to assist in emptying the chamber. A pressure balancing duct is indicated at 13. As the moving member 4 is completely housed, the device is suitable for handling radio-active liquids, e.g. metering plutonium oxalate from a precipitator, and the rate may be controlled by maximum and minimum level probes in the precipitator. The member 4 may alternatively be a rotating disc having a number of chambers which are sequentially connected to inlet, outlet and gas ports or may be a shaft which rotates in a housing and has a transverse chamber connecting with radial ports in the housing.

[Also in Division F4] In heat exchange apparatus, wherein a steel pipe 4 carrying water to be heated extends through a steel container 1 containing a heatstorage material of low thermal conductivity 3, such as sodium hydroxide, the pipe is sealingly secured to the wall of the container by a tubular sleeve 5, which surrounds and is spaced from the pipe, and, which is welded at its opposite ends 7 and 8 to the container wall and pipe respectively. As shown, the sleeve extends outside of the container and the annular space between the sleeve and pipe is filled by the low thermal conductivity, heat storage material which acts as an insulator. In a modification, Fig. 2 (not shown), the sleeve extends into the container, the annular space between sleeve and pipe then being filled by atmospheric air or by insulating material such as the insulant 2 around the container. The connecting sleeve arrangement is said to reduce stresses due to thermal expansion and contraction to acceptable levels. The ratio of the length of the sleeve to the diameter of the conduit is more than 1 : 1, and preferably in the range 4 : 1 to 10 : 1. The ratio of the sleeve mean diameter to the sleeve wall thickness should be in the range 7 : 1 to 12 : 1, preferably 9À5 : 1.

Patent GB-682668-A (GB)
Title: Improvements in and relating to the selective hydrogenation of butadiene
IPC: C07C5/03
Filed: 1949-01-19
Abstract: Butadiene is selectively hydrogenated in a mixture of hydrocarbons having four carbon atoms in the molecule by bringing the mixture of hydrocarbons into contact with hydrogen at elevated temperature and at atmospheric or higher pressure in the presence of a catalyst consisting essentially of unsupported partially reduced mixed oxides of copper and chromium.  The process is carried out at a temperature in the range 200-270 DEG  C. and at a pressure between atmospheric and 10 atmospheres.  The preferred molecular ratio of hydrogen to butadiene is 2 : 1.  The copper to chromium content of the catalyst should be in the molecular proportion of about 0.5 : 1 to 1 : 1.  It is advantageous to incorporate a small amount of magnesium, for example about 0.04-0.05 gram-molecule per gram-molecule of chromium. The catalyst may conveniently be prepared by treating a solution of copper nitrate and chromium trioxide in equimolecular proportions with ammonia to precipitate hydroxy-ammonium chromate.  The precipitate is filtered and dried and then decomposed by heating to give the mixed oxides 2CuO.Cr2O3 in powdered form. The powder is then granulated with a paddle mixer.  If desired, some magnesium chromate may be added to the water used for granulating.  The resulting granules are dried and, after the addition of graphite as lubricant, are pelleted.  Alternatively to, or in addition to, adding magnesium, the mixture of oxides may be treated before granulation with a 15 per cent solution of acetic acid.  Prior to use the catalyst pellets are partially reduced in hydrogen at a temperature of about 300 DEG  C. In the examples, mixtures of butadiene with other hydrocarbons containing four carbon atoms are subjected to hydrogenation in the presence of a catalyst, prepared as described above, resulting in the selective hydrogenation of butadiene.ALSO:A catalyst for the selective hydrogenation of butadiene contained in mixtures of hydrocarbons having four carbon atoms to the molecule consists of unsupported partially reduced mixed oxides of copper and chromium. The catalyst may be prepared by treating a solution of copper nitrate and chromium trioxide with ammonia to precipitate copper hydroxy ammonium chlorate; the precipitate is filtered, dried and heated to give the mixed oxides 2CuO, Cr2O3 in powdered form.
