Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a manipulator device for use in the inspection and/or repairing of the tubing used in a steam generator for a nuclear reactor, which generator has at least one chamber in which a bundle of tubes open into a tube plate, said manipulator device being adapted to be introduced through an opening in the steam generator locked to the tube plate and carry remotely controlled inspection instruments and/or tools which may be monitored, said device comprising a column adjustable along its principle axis, a main arm connected to said column which is adapted to be moved relative to the column and relative to an associated tool carrier or together therewith and means by which the device may be temporarily releasably connected with an installation rod.  With this device the checking and repairing process may proceed in such a manner that operating personnel do not have to enter the steam generator chamber in order to install or remove the manipulator device in the steam generator chamber.          In addition, exact positioning and smooth course of the work is ensured.  Thus the manipulator device comprises a column and a main arm connected to the column by a coupling as well as a tool carrier that is associated with the main arm.  After the column has been installed and locked by pins in two tubes in the tube plate of the steam generator the column is secured by supporting the foot thereof on the floor by means of a vertical drive.  By means of a guide rail and an installation rod the main arm together with the tool carrier are introduced through the opening and con-nected to the column through the coupling.  The coupling segment is integrated into a combined vertical and traverse drive that is associated with the column.  Using this, the main arm is moved vertically upwards into its measuring position.  The drive element associated with the tool carrier together with the vertical and traverse drive allows relative movement of the tool carrier and the main arm in relation to each other and in relation to the column.

Abstract: A B S T R A C T           A SEALING SYSTEM FOR USE ON AN OFFSHORE PLATFORM   AND A METHOD FOR APPLYING THIS SEALING SYSTEM      On offshore platforms, in particular on offshore platforms for the production of crude oil or gas, it is necessary to separate so-called safe areas from so-called classified areas, in order to prevent the passage of oil, gas, vapour, smoke and flames. Consequently, gaps between units on the platform or gaps between said units and parts of the platform have to be sealed. Said units are for example equipment-containing modules which are generally used on offshore platforms. The invention relates to a new sealing system for this purpose comprising a barrier of polyurethane foam, foamed in-situ, and arranged in the gap, at least part of the surface of said barrier being covered with a coating of a fire-protective material.

Abstract: PROCESS FOR PREPARING P-AMINOPHENOL AND ALKYL SUBSTITUTED P-AMINOPHENOL          Abstract of the Invention A process for the production of unsubstituted and lower alkyl substituted p-aminophenols.  A charge mixture is prepared comprising an unsubstituted or lower alkyl sub-stituted nitrobenzene substrate, a platinum catalyst and a sulfur compound.  The sulfur compound may be a divalent sulfur compound in which sulfur is bonded to two other moieties or a compound reducible to such sulfur compound under catalytic hydrogenation conditions.  Hydrogen is introduced into the mixture while it is agitated at a temperature of 0-40°C, thereby reducing the substrate to an unsubstituted or alkyl substituted phenylhydroxylamine.  The hydroxylamine is there-after heated to a temperature of at least 70°C and agitated at at least 70°C in the presence of a highly dissociated acid, thereby effecting rearrangement of the hydroxylamine to the corresponding p-aminophenol.

Abstract: An exercise-responsive cardiac pacemaker is provided which physiologically controls the stimulation rate of a heart by sensing the venous blood temperature in the right ventricle of the heart. A temperature sensing means which includes a thermistor produces an output signal which is sent to an algorithm implementing means for implementing the output signal by an algorithm which represents the mathematical function between venous blood temperature in the right ventricle and heart rate in a normally functioning heart.  The algorithm implementing means produces an output signal which is variable between a maximum and minimum level corresponding to the desired maximum and minimum levels of heart rate in a normally functioning heart.  The algorithm implementing means is also programmable by telemetry after implantation.  A cardiac pacemaker is connected to the algorithm implementing means and is responsive thereto in order to variably control the stimulation rate of the heart.

Abstract: TITLE                      FORCE-BALANCE DRAG ANEMOMETER     INVENTORS Roger Van Cauwenberge Jiri Motycka ABSTRACT OF THE DISCLOSURE         The anemometer is for use in measuring two orthogonal velocity components of a fluid, such as air or water.  When used to measure wind speed, the wind force acting on a sphere attached to a shaft tends to deflect the shaft from the neutral position.  This deflection is measured by optical or electromagnetic sensors which control an electromagnetic actuator which generates a force opposing the wind force thereby return-ing the shaft to the neutral position.  The actuator generated a force proportional to the square of the current applied to the actuator coils. Since the drag force is proportional to the fluid velocity squared (for one dimensional measurement), the wind speed measurement derived from the current applied to the electromagnet will be partly linearized.  A micro-processor is used to compute the wind speed components or the wind speed and its direction from the electromagnet signals.

Abstract: ABSTRACT           Apparatus for controlling tracking position of a magnetic head for reproducing signals recorded as a series of slanted parallel tracks on a magnetic tape, the parallel tracks contain a video signal and a pilot signal of mutually different frequencies that change cyclically from track-to-track.  A reference pilot signal having the same frequency as the frequency of the pilot signal reproduced from the track is generated, and the frequency of the reference pilot signal associated with one track is subtracted from the frequency of the pilot signals reproduced from the tracks adjacent the one track, so as to produce a control signal indicative of head displacement relative to the one track to be reproduced.  In a still picture reproducing mode, first and second reference pilot signals are alternately generated that have the same frequency as the pilot signals that were recorded in the pair of tracks to be reproduced in the still picture mode.
