Patent GB-1543939-A (GB)
Title: Gate valve
IPC: F16K3/30
Filed: 1976-07-15
Abstract: The valve has two mutually opposite, identically shaped plates (100, 102) which, after being assembled, are connected to one another on their inner side by a locked, segmental hub and are spaced apart at a predetermined distance by a spacer ring (120). The individual plates (100, 102) allow independent axial bending so that, despite changes in dimensions and in the angular position of the respective seating surfaces relative to one another, the outflow-side valve seat can perform its sealing function or adapt to the mating seating surface irrespective of these changes. The spacer ring (120) surrounds the segmental hub and has a considerably smaller diameter than the valve seating surfaces in order to increase the flexibility of the valve plates (100, 102). If, following repair work, the seating surfaces have been machined, the desired total width of the valve closing element can be reestablished by replacing the spacer ring. <IMAGE>

Title: Improvements in and relating to the production of esters
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C67/08
Filed: 1950-12-05
Abstract: In a process for the production of esters, in the absence of acid catalysts, a high boiling alcohol (i.e. having a boiling point in the range 170 DEG  C. to 260 DEG  C. under reaction conditions) is reacted at a temperature within the range 170 DEG  C. to 260 DEG  C. with a di-carboxylic acid or an anhydride thereof, in the presence of at least one non-catalytic solid adsorbent the vapours evolved are condensed, the condensate is allowed to separate into two layers, the alcohol-rich layer is returned to the process and as liquid product is obtained an ester which is substantially water-white and has improved thermal stability.  Suitable adsorbents are alumina or silica which may be in the form of gels, aluminium silicates and clays, e.g. as used in oil-refining processes, diatomaceous earth, kieselguhr and active carbon.  The alcohol may be aliphatic, alicylcic or aromatic.  When the alcohol has a boiling point at atmospheric pressure above 260 DEG  C. the process may be operated under reduced pressure to bring the reaction temperature within the prescribed range.  The acid should have a boiling point higher than that of the alcohol.  Specified are maleic, succinic, adipic, phthalic, isophthalic and terephthalic acids and maleic and phthalic anhydrides.  In an example there are reacted phthalic anhydride and an alcohol prepared by reacting carbon monoxide and hydrogen with a mixture of olefines containing 6 to 8 carbon atoms (A) for comparison purposes in the presence of a sulphuric acid catalyst and (B) in the presence of activated alumina with distillation of alcohol and water from the mixture, and continuous return of the alcohol-rich layer after separation.  Specification 667,109 is referred to.

Title: Improvements in or relating to air compressors cooperating with internal combustion motors to form a driving gas producer
IPC: F02B33/44
Filed: 1934-10-18
Abstract: 440,837. Air compressors. AKTIEBOLAGET GOTAVERKEN, Gothenburg, Sweden. Oct. 18, 1934, No. 29893. Convention date, Oct. 20, 1933. [Class 8 (i)] [See also Group XXVII] An air compressor driven by an internalcombustion engine and co-operating with the engine to supply a mixture of scavenging air and exhaust gases at super-atmospheric pressure for use as a driving gas for other expansion motors has a main piston valve 13 controlling the intake passage 10 of the compressor to the suction chamber 5 and auxiliary spring-loaded valves 20 controlling direct communication between the atmosphere and the suction chamber. On starting of the unit, the main valve 13 is closed and valves 20 supply air at a pressure below atmosphere to the suction chamber 5 giving a higher ratio of compression than normal in the compressor cylinder 1 and as a consequence a higher temperature of the air supplied to the internal-combustion engine. This higher temperature at the start facilitates combustion of the fuel and the throttling of the compressor intake substantially unloads the compressor. The valve 13 is opened for normal operation and as the pressure in the suction chamber 5 approaches atmospheric the valves 20 cease to function.

Void [Abridged as open to inspection under Sect. 91 of the Acts, April 29, 1935]. [Class 40 (v)] Relates to apparatus for transmitting light signals, more particularly for use in light telephony, in which a divergent pencil of rays emanating from a source b is rendered parallel by means of an optical system comprising a converging lens c, totally reflecting prism d and objective e, a glass body h adapted to be vibrated in accordance with the sounds to be transmitted by means of a magnet system h<1> and armature h<2> being arranged against the surface d<1> of the prism d, so as to change the quantity of light reflected by the surface d<1> according to the oscillations of the body h.

Title: Improvements in or relating to organic reactors
IPC: G21C1/08
Filed: 1956-10-02
Abstract: 822,163. Nuclear reactors. NORTH AMERICAN AVIATION Inc. Oct. 2, 1956 [May 23, 1956], No. 29974/56. Drawings to Specification. Class 39(4). In a nuclear reactor, a single organic liquid, for example terphenyl, is used as the moderant, coolant and reflector. The enriched uranium, plutonium or thorium fuel rods are mounted vertically inside two concentric steel thermal shields which are surrounded by a steel gamma ray shield having a further thermal insulating lining. The control and safety elements consist of steel plates, coated with boron carbide and aluminium, and are moved horizontally through the core by a hydraulic system. The control system is adjusted automatically by a neutron level monitor. The fuel elements consist of long, thin, plates, clad in stainless steel or zirconium, and are mounted, in boxes of aluminium, steel or zirconium, so that the concentration of elements is highest at the core centre, to produce a uniform thermal flux. A single access opening in the upper surface of the shield permits servicing of all the fuel elements ; the opening is formed in a disc rotatable within a second rotatable disc, the disc axes being spaced apart. The coolant is first pumped upwards between the gamma-ray shield and the outer thermal shield and then down between the outer and inner thermal shields to a chamber at the base of the reactor from which it flows upwards, through the core to the outlet. The coolant decomposition products are burned after removal of the radioactive components.
