Title: Apparatus for the explosive deformation of tubular blanks
Inventor: PETKOV GEORGI KOSTOV
IPC: B21D26/08
Filed: 1983-10-21
Abstract: Apparatus for hydroplastic deformation of a tubular blank under the force transmitted through a lubricating coolant by an explosive blast comprises a housing (1) containing front and rear stop members (2) and (3) respectively. The rear stop member houses a working tool (15) and has an explosion chamber (10) positioned behind it. The front stop member (2) houses a travelling cylindrical piston (7) in whose interior a tubular blank (8) is to be disposed. The cylindrical piston is fitted with one end on a fixed ram (6) and has its other end entered by the working tool (15) which is to be driven therethrough by the pressure exerted thereon by fluid when explosion takes place. A recoil chamber (9) at the remote end of the traveling cylindrical piston (7) completes a fluid duct system providing for location of fluid at both ends of the travelling cylindrical piston, that end at the opposite end to the recoil chamber (9) being in a compensating chamber (12) surrounding the working tool (15). All lubricant containing zones intercommunicate through appropriate ducting, including radial ducting (17) from a blind bore (16) in the working tool (15). The working tool carries a sealing member (18) which enters the tubular blank (8) to define a further fluid containing chamber (19) between sealing member and working tool in communication with the other aforesaid fluid-containing chambers. <IMAGE>

Patent GB-2147287-A (GB)
Title: Alkali-resistant refractory compositions
Inventor: ROWLAND GEORGE ROBERT
IPC: C03B5/43
Filed: 1984-09-14
Abstract: A refractory composition particularly useful in constructing glass furnaces is based primarily on silica (16-20%), alumina (67-75%), and zirconia (14-20%), wherein the silica content is primarily tied up in zircon. As a result of the silica content being bound in zirconia, less silica is available to form alumino-silicates which have a tendency to react with sodium vapors to form sodium alumino-silicates, which, during furnace operation, causes the refractory to spall or flake off. The composition can be formed using inorganic bubbles having reduced weight and, accordingly, is particularly advantageous in forehearth superstructures of glass furnaces.

Title: Depth sensor
Inventor: BUTLER JOHN ROBERT
IPC: G01V3/06
Filed: 1985-02-01
Abstract: A sensor 1 for indicating the depth at which an object is buried employs in-line marker detectors 24 mounted on a sled 3. In use as a depth sensor for buried submarine cables 6, the sled 3 is dragged along the seabed 13. By arranging the detectors 24 so that a pair of their axes of detection 27 intersect below the seabed 13, the sensor 1 can indicate whether a cable 6 lies above or below the intersection point 25. By also arranging the detectors 24 so that a second pair of their axes of detection 27 extend in parallel below the seabed 13, the sensor 1 can indicate the actual depth at which a cable lies. The detectors 24 are mounted so as to provide a similar array of detection axes 27 for each face of the sled 3 on which it is likely to land when first installed on the seabed 13 e.g. detection whose axes of detection intersect at 26. Various detector arrangements are described. <IMAGE>

Title: Regeneration of a reference image
Inventor: COY DIETER
IPC: G06T7/20
Filed: 1987-02-05
Abstract: A method of regenerating a reference image comprises storing the image, which is derived from an actual image (b) of a scene picked up by an image-generating sensor, in a store (2). A correlator (1), to which the actual image and the reference image are conducted, supplies a correlation result which is conducted to a logic decision system (3). The actual image and the reference image are conducted to the logic decision system. The system determines, in dependence on the comparison of the correlation result, the actual image and the reference image, two weighting coefficients (k1, k2) which have individual values between 0 and 1 and a sum value of 1. A regeneration of the stored reference image is undertaken in the case of changes relative to the actual image. <IMAGE>

Patent GB-2214742-A (GB)
Title: Noise-controlled frequency-modulation signal detector
Inventor: JAEGER ERIC
IPC: H03D3/28
Filed: 1988-01-18
Abstract: A noise-controlled frequency-modulation signal detector comprises a quadrature detector 4 turnable to resonate at noise frequencies within a specific band at an input thereto and to produce two 180 DEG out-of-phase outputs, a differential amplifier 22 to which d.c. components of the outputs are fed (via loop filter 21) and which is arranged for producing a control signal in response to a difference between said components, and means responsive to said control signal for retuning the quadrature detector 4 to a point of maximum energy distribution within the specified frequency band. The detector includes a parallel resonant circuit shunted by varactor diodes controlled by the feedback signal. This gives compensation for temperature drift and allows stable operation of the detector, since it remains locked to its input frequency even in the absence of received signal. If noise levels are sufficient to drive the discriminator, the control loop will cause it to settle at a frequency where the mean energy density on either side is equal. Manual adjustment 24 may be required if the energy is not uniformly distributed. <IMAGE>

Title: Stationary cell culture system
Inventor: ALAM AFTAB
IPC: C12M3/06
Filed: 1988-07-07
Abstract: A cell culture suspension is introduced into at least one environmentally controlled narrow culture channel (7) arranged in a reactor (3) and a supply of nutrient and a gaseous phase containing oxygen and carbon dioxide are brought into contact with the cell culture suspension so as to form desired cell cultures. The surrounding environment (11) within the reactor is controlled to suit the required cell culture in the channel, and the nutrient is brought into direct contact by hollow fibre capillaries (28) with the cell culture suspension in the channel, whereas the wall of the channel is gas-permeable so as to allow the gaseous phase to diffuse through the wall and into contact with the cell culture suspension. The oxygen content of the gaseous phase diffuses into the cell culture and maintains oxygen supply for the cellular respiration and the carbon dioxide content diffuses into the cell culture to maintain a desired pH value for the cell culture. <IMAGE>

Patent GB-2222247-A (GB)
Title: Distributed fibre optic sensor system
Inventor: DAKIN JOHN PHILIP
IPC: G01D5/26
Filed: 1988-08-23
Abstract: Changes in environmental parameters are sensed transmitting pulses of light which are frequency shifted in relation to one another along an optical fibre. At least one pulse of light has a first frequency and a subsequently transmitted pulse of light has a second frequency, the pulse of light having the first frequency being scattered or reflected from a first location along the optical fibre and combined with light scattered by the second pulse from a second location along the optical fibre to produce an interference signal. The interference signal is detected and processed to derive information representative of changes in environment parameters affecting at least part of the length of optical fibre between the first and second locations. As shown, switch and frequency shifter 4 produces two pulses, spaced in time and of different frequency which are launched into optical fibre 6. The first pulse, after reflection from the end of the fibre 12, interferes with light backscattered from the second pulse at A producing a difference frequency signal phase modulated by phase changes in the fibre between A and end 12. Alternative embodiments use two pulses of the first frequency before the second frequency pulse to define the section of fibre sensed, or use interference of backscatter from both pulses. <IMAGE>
