Title: A tubular reactor and process for supplying granular catalyst material and/or liquid into the tubes of the tubular reactor
Inventor: SUPP EMIL
IPC: B01J8/00
Filed: 1987-01-13
Abstract: The reactor tubes 8 of a tubular reactor are mounted in an upper tube plate 6 and are surrounded by a liquid coolant during operation. A vertically movable distributor plate 15 is disposed over the upper tube plate and is provided with distributor tubes 18, which extend into the top portions of the reactor tubes. Granular catalyst material is first supplied onto the distributor plate, and then through the tubes into the reactor tubes. The catalyst material on the distributor plate is then removed and the plate is raised so that the distributor tubes are emptied. The reactor tubes are thus filled except for an upper volume, which remains free of catalyst. The distributor plate may also be used to distribute liquid into the reactor tubes. <IMAGE>

Title: A vehicle battery isolating switch
Inventor: THOMPSON HARRY MARSH
IPC: H01H35/14
Filed: 1987-05-12
Abstract: A vehicle battery isolating switch capable of positive local manual operation or of remote electromechanical operation or by de-acceloration forces such as may occur under road crash conditions.   As will be seen from Fig 1, the electrically insulating slidable member 4 carrying the floating disc contact 5 disconnects an electrical circuit when moved in the direction of the arrow eg, by an inertia weight 13 that must overcome the frictional forces of a spring-loaded detent 12, or a shear pin. The spring loaded detent 12 drops through the opening 14 in the member 4 so providing positive isolation and preventing accidental rebound operation. The switch is reset by the lifting of lever 15 either locally or remotely. The battery isolating switch may be mounted either directly onto the battery post via a mount 2 or be fitted into the battery case or some distance from it and is designed to stop minor electrical fires such as may be caused by dampness or mechanical damage, before they can escalate into major confragrations. <IMAGE>

Title: A waveguide of square cross-section for carrying circularly polarized electro- magnetic energy
Inventor: KINSELLA PHILIP JOHN
IPC: H01P1/02
Filed: 1988-04-11
Abstract: A bend in a square-section waveguide (X3) creates a relative phase delay between orthogonal components (P1,P2) of circularly polarized energy travelling along it thereby distorting the circular polarization into elliptical form. To compensate for this, one or more devices (CD) are included incorporating inductive (L1,L2) and capacitative (C1,C2) elements co-operating to form a filter. This filter delays that component of the polarization which is not delayed by the bend. Suitable adjustment of the filter can be made to ensure that the two delays are equal thereby avoiding the afore-mentioned distortion.

Patent GB-712644-A (GB)
Title: Improvements in or relating to manufacture of tetraethyllead
IPC: C07F7/24
Filed: 1952-01-11
Abstract: <PICT:0712644/IV (b)/1> Tetraethyl lead is prepared by a continuous process which comprises feeding an alkali metal alloy of lead and a liquid ethyl ester of an inorganic acid to a reaction zone in excess over the quantity required to form tetraethyl lead, and agitating the mixture sufficiently to maintain the reacting and reacted solids in nonuniform distribution in a liquid so that the concentration of solids decreases from the bottom of the reactor upwards, the liquid comprising a solution of tetraethyl lead in the ethylating agent, said liquid being of uniform composition throughout the reaction zone, and withdrawing at a point remote from the bottom of the reaction zone a slurry of solids in the liquid, said solids being more highly ethylated or contain more reacted solids than the solids at the bottom of the reactor.  The ethylating agent may be ethyl chloride, bromide or iodide, or diethyl sulphate.  The alloy may be fed to the reactor as a comminuted solid or as a liquid. Monosodium-lead alloy is the preferred lead alloy although other lead alloys may be used, e.g. the disodium-lead alloy or other lead alloys containing greater or smaller proportions of sodium.  Other alkali metals may replace or partially replace sodium in the lead alloys, e.g. potassium may be present.  Ethyl chloride and monosodium-lead alloy may be fed to the reaction zone in the proportion of at least 2 parts by weight of ethyl chloride to 1 part by weight of alloy, the preferred point at which the slurry of solids is withdrawn being in the upper 50 per cent of the total depth of the reaction mass so that a liquid to solids weight ratio within the reaction zone of at least 3 : 1 to 5 : 1 is obtained.  A suitable apparatus for carrying out the process is shown in the Figure.  Ethyl chloride is fed from tank 2 through pipe 3 and the alloy is fed from hopper 4 via the pressurized chamber 5 and conveyer 8 into the reactor 1, both the hopper and pressurized chamber having an inert gas atmosphere.  The reactor is fitted with a jacket 23 for a heat transfer media introduced through line 24 and discharged from 25. Propeller type agitators 29, 30 and 31 and bottom plate element 32 are mounted on shaft 33.  The ethylated mixture is discharged through one or more nozzles 131, 132, 133, 134, 135 and 136 into the solids-liquid separator 16, the solids being removed through line 17 and the liquid phase is removed through line 18 for the recovery of tetraethyl lead. In an example, tetraethyl lead is prepared from ethyl chloride and monosodium-lead alloy in the apparatus illustrated in the Figure.

Title: Telecine test pattern generator
Inventor: MEAD TERRENCE WILLIAM
IPC: H04N3/20
Filed: 1989-12-22
Abstract: A video system, particularly a telecine system, includes a RAM store 50 for video weighting or correction factors and a multiplier 53 for multiplying the video signals x' by the stored weighting factors. For system test purposes, a test pattern is loaded into the store and the video input to the multiplier held at unity. The test pattern may replace or supplement the weighting factors according to whether a high or low resolution test is required. As described, a map of correction factors is generated from the response of an area to illumination when no film is in the film-gate. If a defect, resulting in a signal below a threshold, is detected then video data from an adjacent area is substituted. Burn at the ends of video lines may be reduced by reducing the intensity and/or dwell time of the scanning spot on any one area of the screen in the vicinity of the line end. The look-up RAM 50 may comprise four banks of identical RAM holding identical data. Each bank is accessed in turn on a different phase of a four-phase clock to provide high speed truly random access. Selected areas of the picture may be blanked by comparing digital scan addresses with reference addresses delineating the area to be blanked and generating a blanking signal when the delineating addresses are exceeded. Effects such as shading, vignetting and borders may be created. <IMAGE>
