Abstract: ABSTRACT OF THE DISCLOSURE         An actuator for variable adjustment of the pistons in hydraulic slave cylinders for regulation of, for example, the elevation adjustment of work stations.  The pistons are actuated by way of a pusher which is non-rotatable but axially displace-able in the actuator housing.  The object is to provide an actuator which requires low installation height, which can be semi-attached  to comprise a large number of pump cylinders without effecting the low installation height, which improves the adjusting possibilities, so that every individual leg cylin-der can be adjusted for balancing of possible irregularities in the floor.  This has been provided by the  fact that in the housing there are provided one or more oblong openings for drivers attachable to the pusher and arranged for cooperation with the corresponding pusher in one or several further actua-tors placeable close to the actuator and that in at least one of the connected actuators there is arranged a threaded spindle for cooperation with a pusher designed as a nut.

Abstract: ABSTRACT         A method and apparatus for compressing alphanumeric data that is stored or transmitted in the form of digital codes.  A dictionary is created which assigns each word of the alphanumeric text and the punctuation that follows it to a unique address or token of, illustratively, up to 16 bits (two bytes).  Each word in the alphanumeric text is then replaced by the address that refers to that word in the dictionary.  Because the dictionary can contain up to 216 = 65,536 entries, it is more than adequate for the storage of the words associated with almost any book.  Because only two bytes of information are needed to address any one of these 65,000 words, replacement of each word of text with two bytes of address information reduces the average of about three.         Further reductions of 25% or more in the length of the compressed text can be achieved in most cases by representing the most frequently used words with tokens that are shorter than two bytes in length.  The number of bytes required to store the dictionary can be substantially reduced by storing the words in alphabetical order and taking advantage of the redundancy in characters that results.  Thus, if the second of two entries contains five letters that are the same as that of the preceding entry, this can be signified by storing one character representing the number 5 and the remaining characters not common to both entries.

Abstract: A B S T R A C T          Television signal component transmission arrangements:                The arrangement contains coders (103,104) which convert the Y, U and V components of a television signal into code words of variable length. These are interlaced in a multiplexer (105) in pulse frames in which permanent positions are allocated. At the receiving end the resultant t.d.m. signal is reseparated in a demultiplexer (112).  Decoders (113,119) re-convert the code words of variable length into the Y, U and V components. By virtue of the allocation of permanent positions in the pulse frames it is possible to reliably separate the luminance and chrominance components at the receiving end, even when the word synchronisation of the individual components is lost.

Abstract: ABSTRACT OF THE DISCLOSURE In detection of a defect in a part of an object having a surface which is substantially a surface of revolution, the surface of the inspected part is illuminated by light rays which are emitted through an annular portion coaxially disposed with the surface of the inspected part, and light rays reflected at the surface of the inspected part are received to form an image of the inspected part.  The image is con-stituted of pixels corresponding to the respective portions of the surface of the inspected part. Signals having a value indicative of the brightness of the pixels are stored in relation to the respective posi-tions of the pixels in the image.  The stored signals are referred repeatedly to provide, as a set of signals, a predetermined number of the signals of the pixels positioned along an imaginary line extending radially through a central point in the image corre-sponding to the axis of the surface of the inspected part and positioned and distributed within a radial range extending along the imaginary line.  Judgement whether or not there is a defect is made in accord-ance with comparison of tha signals of each set with a preset value, and with comparison between signals of two sets which are positioned along two of the imaginary lines which are proximate to each other.
