Title: Relative movement detector for tubular furnace - triggers pulses at time intervals for remote control of plant
Inventor: FLEISCHER JOACHIM
IPC: F27B7/42
Filed: 1976-02-25
Abstract: Detector is used for determining relative movements between rotating tubes and the support ring of a rotary furnace. Relative movement is generated which is approximately equal to the circumference difference of the components rolling within each other. System produces measured values which can be transmitted to a switching station for remote control of the necessary play between the rotating tube and the bearing ring. These switching pulses are measured at intervals and the relative movement is evaluated from this information. The switching pulses are caused by opening and closing of a contact arrangement in an electrical circuit. One switching pulse is triggered for a relative movement of given extent or for a certain equal angular range. The time intervals of the switching pulses can be recorded on a time recorder for producing relative movement diagrams.

Title: Normalised serum thyroxin assay - compensated for changes in thyroxin-binding globulin levels, extraction with acid to release complexed thyroxin
Inventor: CUMMINS LAURENCE MARK
IPC: G01N33/78
Filed: 1976-03-01
Abstract: Method for determination of normalised serum thyroxin levels comprises (i) extracting thyrosin (I) from thyroxin-binding globulin (TBG) by mixing he sample with an extracting agent which contains a dil. acid chosen from HCl; H2SO4; H3PO4; HNO3; HNO2; aliphatic amino-, carboxylic- or dicarboxylic acids; aromatic amino-, hydroxy- or dicarboxylic acids or their mixts., (II) mixing extracted (I) with TBG saturated with radiolabelled (I), the amt. being sufficient for labelling; (III) contacting the mixt. with a second binding agent (II), (IV) incubating, (V) measuring initial radioactivity of the incubated mixt., (VI) separating the mixt. and measuring residual activity in remaining (II).. Since acid extraction destroys the (I)-TBG complex, the method gives a value of (I) concn. compensated for changes in TGB levels (which may occur during pregnancy, oestrogen therapy etc). So gives a true indication of the status of the thyroid gland.

Title: Caesium or rubidium hydroxide prodn. from corresp. alum - using anion exchanger charged with hydroxide ions and anionic complexing agent
Inventor: SCHOLZ EUGEN DIPL CHEM DR
IPC: C01D17/00
Filed: 1976-11-10
Abstract: In the prodn. of CsOH or RbOH from the corresp. alum using an ion exchanger, an aq. soln. of the alum is passed over an anion exchanger charged with OH ions and an anionic complexing agent of the aminoacetic acid type, pref. EDTA, and the Al-free soln. is used as such or dried. The hydroxides are valuable intermediates in the prodn. of the corresp. alkali cpds.

Title: Producing radiation line focus on moving workpiece - esp. for automatically welding layered or tubular synthetic film
Inventor: WHITTLE HARRY REED
IPC: B29C65/74
Filed: 1976-12-23
Abstract: A device for treating a workpiece by moving focused radiation across it, e.g. in the welding of a synthetic film, includes an optical system for the prodn. of a line focus of a radiation beam on the moving workpiece, so that the direction of the line focus is at right angles to the direction of motion of the workpiece. It includes also means of deflecting the focussed beam over the workpiece in a direction which has a component in the direction of motion of the }workpiece of such a dimension that the actual motion of the line focus of the radiation beam relatively to the workpiece takes place in a straight line along the line focus. The optical system consists of a cylindrical focussing leans, a spherical intermediate focussing lens and a projecting lens. The deflectors consists of a mirror positioned between the intermediate lens and the projector, the alignment of which, relatively to the cylindrical lens can be altered, so as to alter the direction of the deflected track of the focussed radiation. Moving workpieces can be treated with a line focus of a radiation beam which moves at the same speed as the workpiece and remains parallel to its starting position. When a band or tube of high pressure polyethylene e.g. has to be cut and welded, a laser, for pref. a CO2-infrared laser is used. More than one line focus can be produced if required by means of a Fresnel bi-prism, and in the prodn. of bottles and sheaths from two layers of film, three line-foci may be produced.

Title: Hydrogenation of sulphur-contg. coal - with sulphur recovery by reacting hydrogen sulphide with sulphur dioxide from residue combustion
Inventor: LEHMAN LEON M
IPC: C10G1/00
Filed: 1977-03-29
Abstract: Continuous hydrogenation of S-contg. coal is carried out by reacting particulate coal with H2 to produce liq. hydrocarbons, H2S and an S-contg. residue. The residue is then burned to produce an SO2-contg. flue gas. The flue gas is scrubbed to remove the SO2, which is then reacted with a stoichiometric amt. of the H2S to form elemental S. Combustion of the S-contg. residue avoids problems of disposal and provides thermal energy, e.g. for steam generation. The S-contg. residue can comprise the uncreated coal solids and/or a residue formed by vacuum distn. of the hydrocarbon product. The flue gas from the combustion of the residue can be scrubbed with an aq. phosphate or citrate soln. The reaction between the SO2 and H2S can be effected in a conventional Claus unit.
