Patent GB-2278363-A (GB)
Title: A method for the prevention of blocking in linear low density polyethylene films
Inventor: PUNGTRAKUL CHALOKE
IPC: C08L23/08
Filed: 1993-05-28
Abstract: A method for the prevention of blocking in Linear Low Density Polyethylene (LLDPE) films comprises the incorporation of at least a preselected High Density Polyethylene (HDPE) resin and a slip additive into the LLDPE film base resin at appropriate let-down ratios. Regardless of the method of incorporation, after the extrusion and as the melt cools the preselected HDPE resin will give rise to the formation of larger crystals. Parts of these larger crystals will protrude from the film surfaces and trap the air, preventing it from being squeezed out from the gap in between two layers of film. Thus an antiblocking effect can be achieved without impairing the clarity, the gloss, the color, and the appearance of the film. In addition, the extrusion will be easier without excessive wears in the screws or the barrels, and certain mechanical strengths of the film may also be improved.
Patent GB-2267979-A (GB)
Title: Method of regulating a continuous process
Inventor: MENAHEM MARCEL
IPC: G05B13/04
Filed: 1993-06-18
Abstract: A method of regulating a continuous process (P) includes a stage of optimizing a model (M) representative of the behaviour of said process (P), in which: a control magnitude (u) is applied both to the process (P) and to the model (M), each of which responds thereto by providing a signal; the two resulting signals are applied to a subtractor (13) to obtain an error signal ( sigma ); and the model (M) is corrected as a function of the error signal ( sigma ); and a subsequent regulation stage in which a control magnitude (u) is permanently applied to the process (P) and to the model (M). Correction is performed by generating discrete cross-correlation functions between the error signal ( sigma ) and the control magnitude (u) for different time offsets ( tau ) between the control magnitude (u) and the error signal ( sigma ), and in modifying the model (M) so as to minimise the sum of the squares of the cross-correlation functions over a time that the process is observed.   <IMAGE>

Title: Free electron laser
Inventor: KESSLER DAVID PHILIP ABRAHAM
IPC: H01S3/09
Filed: 1995-05-05
Abstract: A Free Electron Laser consists of a chamber containing a photon retardant, an electron donor (4) inside said photon retardant (3), anode (1) and cathode (6) end-plates, an photon window in the cathode and electromagnetic coils surrounding the chamber (2). A large current is passed through the electromagnetic coils generating a magnetic field inside the chamber. causing the electron donor to emit electrons which cross the hollow center (5) thereby impacting with the electron donor on the other side, thereby stimulating the emission of photons which in turn strike the electron donor, thereby freeing more electrons. A large potential difference is set up between the end-plates, sending a swarm of electrons to the anode (1) which emits electromagnetic radiation some of which strikes the energetic electrons in the hollow center of the tube thereby stimulating the emission of coherent electromagnetic radiation which can escape through the window (7). If the donor (4) is an alkali metal such as caesuim, and the retardant (3) is lead, the laser can be used to generate X-rays. In this case, molten lead and molten caesuim are concentrically positioned in the chamber by rotating the chamber fast.

Patent GB-966409-A (GB)
IPC: G21C5/14
Abstract: 966, 409. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. March 11, 1963 [March 29, 1962; Jan. 15, 1963], Nos. 12078/62 and 7788/63. Heading G6C. In a heterogeneous nuclear reactor having a solid moderator interspersed with fuel elements, the moderator is in granular form and means are provided for renewing the moderator by granular flow. In the drawing the moderator is in the form of spherical graphite granules of an average diameter between ¢ and 1 inch and is contained in a tank 12 mounted within a concrete pressure vessel 15. Twelve heat exchangers 18 (of which only one is shown) are mounted around the core tank with a cylindrical radiation shield 19 interposed to reduce radiolysis of the water in the heat exchangers. Four circulators 27 having impellers within the reactor vessel and driving motors outside are disposed around the core between the heat exchangers and circulate carbon dioxide coolant through the core and heat exchangers. The core tank is penetrated by upright fuel assemblies 29 each of which comprises a number of fuel rods supported on grids attached to a stainless steel stem 31 and enclosed in a graphite tube 34 through which the coolant flows. Each tube 34 is joined at its upper end by a flexible coupling 30 to a stainless steel tube 36 which is jointed to a shield plug 38, the tube 36 being provided with slots 40 to allow coolant to flow out. The moderator is coolant by coolant flowing through a branch tube 42 into the plenum 13 at the top of tank 12 and through the moderator to apertures 43 in the lower ends of fuel tubes 34. To charge the reactor the fuel assemblies are inserted and the moderator granules are poured into the core tank through tubes 44. Valved nozzles 45 fitted to the bottom plate of the core tank allow high pressure coolant to be injected into the moderator to fluidise the granules and so achieve maximum packing density. To replace a fuel assembly the reactor is shut down and its pressure reduced to atmospheric pressure. The assembly is then removed and some of the moderator granules will flow through the exposed aperture into the tundish 21 and can be removed through an outlet 22. The new assembly is inserted, if necessary after employing a sweeping implement to clear away any granules obscuring the aperture below the assembly, and the moderator is topped up by pouring granules through tubes 44. The moderator granules may be graded in size or they may be in the form of flat discs on platelets. In an alternative reactor the fuel tubes are closed at their lower ends and a re-entrant cooling system is provided for each fuel assembly.
