Abstract: APPARTUS FOR SYNCHRONIZING CARRIER SPEED AND PRINT CHARACTER SELECTION IN ON-THE-FLY PRINTING             Abstract of the Disclosure A rotatable print disk is mounted on a carrier which traverses along a print line.  The disk is rotated from each selected character position to the next selected character position by the shortest distance at a constant velocity; thus, the time for the disk to move from a given selected character position to the next will be variable dependent on this distance.  The carrier is moved from one print position to the next at variable speeds selected such that the carrier reaches the next print position in synchronization with the disk reaching the next selected character position.  Upon such synchronization, a print hammer is fired to print the character while the carrier continues on-the-fly towards the next print position.  The apparatus includes means responsive to the time required for the print disk to rotate from one selected character position to the next for controlling the carrier escape-ment velocity to increase and/or decrease such that escapement occurs coincident with character selection without escapement velocity becoming zero.

Abstract: ABSTRACT OF THE DISCLOSURE A device for blowing gas and a finely-divided solid into a metallur-gical melt is disclosed, the device having a blast pipe which has at one end an inlet connected to a gas source and at the opposite end an outlet immersed below the melt surface in order to blow the gas into the melt.  A cooling device surrounds the blast pipe, the cooling device having, at that end which is near the blast-pipe inlet, inlets and outlets for the cooling medium, and a layer of ceramic material which surrounds at least the lower part of the cooling device.  In the outlet of the blast pipe there is a Laval nozzle which is at an angle to the blast pipe and extends through the thermally insulating mantle.   The cooling device further consists of smaller-diameter cooling pipes extending parallel to the blast pipe, the inlets of the cooling pipes being intended to be connected to a source of a gas-liquid mixture which vaporizes rapidly in the cooling device.  The said layer is surrounded by a graphite or silicon carbide sleeve, which is at least thick enough to protect the ceramic material when the device is lowered into the melt, so that the ceramic material reaches the temperature of the melt more slowly than does the sleeve and sinters before the sleeve wears out.

Abstract: ABSTRACT OF THE DISCLOSURE A digital data signal is distorted by means of a low or high pass filter,  Quantization of such a signal in accordance with extracted clock pulses will result in a high error rate if a fixed quantization level is utilized due to attenuated voltage swings and a low differential between the signal excursions and the quantization level.  The present invention overcomes this problem by means of a shift register connected to an output of a quantization comparator which is clocked by the extracted clock pulses.  A weighting circuit is connected between the shift register and one of the inputs of the comparator to suitably adjust the relative quantization level to compensate for the asymmetrical voltage swings caused by the filtering and thereby greatly reduce the data error rate.

Abstract: Abstract The invention relates to a method to be used in an air space surveillance radar for selecting target data by comparing the target azimuth extent data with the zone-related threshold. A plot generator comprising a video processor produces, upon the reception of sensor signals, target data per target, which data are stored in a register. The method aims at protecting the track-generator from overloads and is characterised by the following process steps: a. to separately store a target azimuth extent threshold for each range-azimuth zone; b. to convert target angle and range data into a zone-related address control signal; c. to read out the zone-related threshold; d. to compare the target azimuth extent data supplied by the video processor with the read-out threshold; e. to produce an erase signal for the register-stored target data if the supplied target azimuth extent data fails to exceed the threshold.

Abstract: ABSTRACT A method for the estimation of an anilide in which the anilide is first hydrolysed enzymatically to an aniline and then the quantity of the aniline produced is estimated spectrophoto-metrically, preferably colorimetrically.  The hydrolysis of the anilide may be catalysed by any enzyme of the type, EC 3.5.1.13, known as aryl acylamidases. Preferably enzymes isolated from the cells of Pseudomonas fluorescens ATCC 39005 or Pseudomonas putida ATCC 39004 are employed.  The aniline may be analysed, for example, by conversion to an indamine, an indophenol or an indoaniline, followed by colorimetric analysis of the coloured quinone-type compound produced.  This conversion may take place in the presence of an oxidising agent, such as a copper (II) salt, and/or a base, such as ammonia.  A diagnostic kit to allow the routine use of the above method is also provided.  In one embodiment of the kit, it comprises, (a) an aryl acylamidase, in solution or on a solid support, (b) an organic compound suitable for the conversion of the aniline to an indamine, an indophenol or an indoaniline, preferably in solution, and (c) a base; preferably in solution.          The kit may further comprise an oxidising agent, again preferably in solution.  The above method of analysis and diagnostic kit may be particularly useful in the estimation of anilide drugs, such as paracetamol, dissolved in biological fluids.
