Patent GB-703182-A (GB)
Abstract: 703,182. Gravity-separation apparatus. HARTLEY, C. J. May 26, 1952 [May 24, 1931]. No. 12135/51. Class 46 A circular settling tank has concentrically arranged in the bottom of the tank mid-way between the centre and the periphery a circular channel into which settled matter is scraped and from which it is drawn up by a pipe delivering into an annular receiver centrally arranged in the upper part of the tank, the settled matter in the receiver being drawn off. Matter settling in the bottom of a tank 10 is scraped into a circular channel 10a and thence siphoned by a pipe 28, carried by a rotating scraper bridge 15, into an annular receiver 23 surrounding and supported by a central feed pillar 12. A pocket 26, of small angular extent, and communicating with the annular receiver 23, is formed between the annular receiver 23 and the pillar 12 at one place. Settled matter collecting in it is conducted along a pipe 27 into a sump 30 for pump or gravitational discharge. A weir 29 spanning the pocket 26 ensures that the lower end of the siphon pipe 28 is always submerged. The inner wall 24 of the annular receiver 23 forms a feed box 25 to divert down. wards liquid entering the tank through a pipe 13 and openings 14 in the pillar 12. The walls of the receiver 23 extend above the top water level of the tank, while its bottom is well below that level. The matter in the channel 10a may be pumped or air-lifted up the pipe 28 as an alternative to siphonic action. According to the Provisional Specification the receiver 23 may be attached' to and thus rotate with the scraper bridge.

Title: Manufacture of synthesis gas by partial oxidation
IPC: C01B3/36
Filed: 1978-07-21
Abstract: In the manufacture of synthesis gas containing CO and H2 by partially oxidizing hydrocarbons or coal with oxygen-containing gas in the presence of a temperature moderator in a non-packed, non-catalytic, synthesis gas reactor at an autothermal temperature of from 900 to 1700 DEG C and at a pressure of from 1 to 250 bars, then cooling the reaction product, separating off particulate carbon, removing acidic impurities and carrying out any further desired aftertreatment, difficulties have arisen over removal of hydrocyanic acid. The present invention removes hydrocyanic acid from the reaction product by treating it, after the step of separating off particulate carbon but before the step of removing acidic impurities, in a catalytic hydrogenation zone at from 100 to 250 DEG C and a pressure of from 1 to 250 bars.
Patent GB-2034040-A (GB)
Title: Improvements in or Relating to Liquid Level Alarms
IPC: G01F23/24
Filed: 1978-11-11
Abstract: A liquid level alarm comprises two electrodes 43, means for monitoring the resistance between them and giving an alarm when the resistance crosses a threshold value and a float switch 44 which disables the alarm when liquid is below a predetermined value. The alarm is used in a drainage system including oil interceptors from each of which oil must be removed when it reaches a preset level to prevent contamination. The float switch is arranged to short circuit the electrodes when liquid is absent thus simulating the presence of liquid. <IMAGE>

Patent GB-2030509-A (GB)
Title: Process and apparatus for the manufacture of ceramic mouldings by injection-stamping
IPC: B28B7/00
Filed: 1979-08-17
Abstract: In a process for the manufacture of ceramic mouldings e.g. a dish by injection-stamping, an excess amount of ceramic material is injected into the cavity 8 of a mould 1 consisting of at least two parts 2,3 before the mould parts are completely closed. Upon or during closing of the sprue, the mould parts are moved together. In order to avoid variations in density and the formation of parts of deficient composition in the ceramic moulding, there are exerted different pressures on the material in different zones. These can be produced by extruding excess material from the cavity 8 through throttling outlets 10a into overflow spaces 12 so that pressure is produced in the edge zone through the throttling action and an increase in density obtained. The height of the outlet 10a may vary along its length. In addition to mould closure, moulding material may be expelled by urging a pin 7 mounted on a screw 6 towards the mould cavity. <IMAGE>

Title: Device for Providing a Pulsatile Blood Flow
IPC: A61M60/569
Filed: 1979-11-05
Abstract: The device has a balloon-like blood container 3 externally pressurised in a pulsate manner by pumping fluid supplied to the interior 8 of housing 1, to give a pulsatile blood flow output. The housing 1 is designed so that abnormal pumping pressure will cause the housing 1 rather than the container 3 to fail. The housing 1 may be flexible and portions 4a and 5a of the housing 1 through which the blood is lead to and from the container 3 may be resiliently deformable. Container 3 can act as a valve member to reduce the pumping fluid evacuation rate if its pressure drops too low. Also described is a method of making such a device involving using the container 3 as a form or mould when making the housing 1. <IMAGE>

Title: Improvements in or relating to methods of and circuit arrangements for measuring the attenuation of optical fibers
IPC: G01M11/00
Filed: 1979-11-30
Abstract: In order to measure the attenuation of an optical fibre 3, a light pulse from a source 2 is coupled into the fiber 3 and a proportion of the light scattered back by dispersion is coupled out of the fibre 3 by a beam splitter 4 to a detector 5. The detector 5 supplies via an amplifier 6 two gate circuits 7, 9 whose outputs are connected via integrators 12 to a logarithmic divider 13. A control unit 1, 8, 10, 11 triggers the light source 2 to supply the light pulse and, after a first predetermined delay t1, opens the first gate circuit 7 for a predetermined period. After a second predetermined delay t2 from the opening of the first gate circuit 7, the control unit 1, 8, 10, 11 opens the second gate circuit for another predetermined period. The output of the logarithmic divider 13 is supplied via an amplifier 14 to a display 15, which can display directly the attenuation of the fibre 3 per unit length. <IMAGE>

Title: Weapon Effect Simulators
IPC: F41G3/26
Filed: 1980-05-22
Abstract: A detection system using photo- diode detectors for detecting an aimed beam of infra-red laser pulses in a weapon simulator is arranged to discriminate between photo-diode signals resulting from true laser signals and those resulting from radar, wide-band or impulsive noise interference. In one arrangement, an auxiliary detector which is sensitive only to the interference (either on antenna or a blackened photo-diode (64)) is arranged to suppress the output of the normal detector (60, 62) in the presence of interference. In another arrangement, where the beam is in the form of bursts of laser pulses at a constant pulse repetition frequency, a common detector arrangement feeds two filters, only one of which is tuned to a harmonic of the pulse repetition frequency. The output of the other filter, indicative of the presence of spurious signals, is used to suppress the supply of any output signal. In one arrangement interference from the sun being interrupted by helicopter blades is detected and discriminated against. <IMAGE>
Patent GB-2081916-A (GB)
Title: Method of producing a positive acting photographic element
IPC: G03F7/095
Filed: 1980-08-01
Abstract: The invention relates to a method of producing a positive acting lithographic element by means of changes in the exposure and development parameters applied to a normally negative acting coated substrate. The substrate has a first coating comprising a water soluble lithographically suitable, light sensitive negative acting aromatic diazo composition and a second layer applied over said first layer of a water insoluble, ink receptive, water permeable negative working lithographic photo-sensitive composition which comprises a water insoluble, water permeable oleophilic resin and the reaction product of a diazo diphenylamine-formaldehyde condensate with a benzophenone sulphonic acid. By subjecting the coated substrate to only 3% to 15% of the light exposure normally necessary to produce a negative acting lithographic element, and subsequently developing the exposed coating with water a positive acting element is produced. The developed element is then further exposed to light to render the remaining coatings insoluble in water.
