Patent GB-467381-A (GB)
Title: Improvements in catalysts
IPC: B01J37/00
Filed: 1936-08-04
Abstract: Catalytic masses with high heat-conductivity are obtained by mixing pulverized catalyst with metal powder and heating in an inert atmosphere to a temperature approaching the melting point of the metal, which is thus converted into a regulus in which the catalyst is embedded.  Preferably the mixture is moulded under pressure during the heating.  In an example, 1 part of vanadium pentoxide is mixed with 1,15 parts by weight of aluminium powder.  The mixture is moulded under a pressure of 3000 atmospheres and heated to 600 DEG C. for six hours.  The product is suitable for use in the oxidation of organic substances.

Abstract: 1,023,091. Photo-electric liquid level indicators. BOULTON PAUL AIRCRAFT Ltd. May 31 1963 [June 7, 1962], No. 22112/62. Heading G1A. A system for indicating the level of liquid in a container 11 includes a source of light (Figs. 4 and 5 not shown) a light sensitive device 16 such as a silicon solar cell and a body 12 of light transmitting material having a surface so inclined to the direction of light from the source incident upon it that when the surface is covered with liquid a substantial proportion of light is incident upon the light sensitive device, but as the surface becomes progressively uncovered by the liquid, the amount of light incident upon the light sensitive device is progressively reduced. The material for the body 12 has a refractive index similar to that of the liquid and as shown in Fig. 1 with the inclined surface completely covered, the light from the source passes through the body to the solar cell 16 connected to an indicating meter 22 which shows full scale deflection. With the inclined surface partially covered light passing through that part of the body above the liquid is internally reflected by the surface array from the cell 16 and corresponding by smaller deflection of the meter 22 is produced. With the inclined surface completely uncovered substantially all the light is reflected and the solar cell receives very little light thus causing a very small deflection of the meter 22. The light source, body and cell together with a lens for the source are constructed as a complete unit (Fig. 4 not shown). Failure of the light source or solar cell produces zero deflection of the meter. A switch is provided in the light source circuit for test purposes. The body 12 may be of acrylic resin material or glass.

Abstract: 1,267,681. Storage of liquefied gas. ESSO RESEARCH & ENG. CO. 1 May, 1969, No. 22297/69. Heading F4P. A method of storing liquefied gas comprises displacing water from a stratum 14 by a purge gas, and then introducing liquefied gas. The purge gas is pumped in through wells 18, 22 and water is withdrawn through encircling wells 20 until the purge gas has produced the desired final volume; The liquefied gas is then introduced through wells 18, 22 and the water in the stratum adjacent the storage reservoir freezes and thus seals the reservoir. Alternatively introduction of the liquefied gas may be started when the purge gas has created only part of the desired final volume. Heat from surrounding strata assists vaporization of the liquefied gas.

Abstract: 282,137. Highfield, J. S., and Highfield, W. E. Sept. 10, 1926. Compressed-air engines.-A reversible, revolving.or radial cylinder, compressed-air motor for operating sluice valves and like wheel-operated devices, is provided with a relatively remote control which through compressed-air actuates a reversing-valve mounted on the motor. The engine and control are described as applied to a water valve. The reversing-valve 33, Fig. 2, comprises two heads either of which is subjected to compressed air through connections 34, 35, and the centre space of which communicates with the exhaust 36. The motor comprises a revolving drum 14 with radial cylinders containing pistons 39 connected to a sleeve on a stationary crank. Circumferential inlet and outlet passages 29, 30 are provided, and auxiliary passages 37, 38 communicate with the end chambers of the reversing- valve so that when one end is put to compressed air a portion of the motor exhaust may pass away through the other passage and operate an indicator to show the distant operator that the motor is working. The motor drives a worm shaft which engages a toothed wheel which through lost motion engages a sleeve on a shaft 3 geared through a friction clutch to the spindle 6 of the water valve. The wheel 6 or the motor-driven worm-shaft may be operated by hand. The construction allows the motor to make several revolutions before taking up the load, and to overrun somewhat when the valve seats. The supply 51 to the reversing-valve through one or other of two passages 10, 11 is controlled by a hand-operated piston valve comprising a body 45 and perforated discs 43. The exhaust from the valve passes through outlet 54 to the indicator. A modification is described wherein a motor with inclined stationary cylinders and oscillating distributing valves is mounted upon the water valve.
