Abstract: PARALLEL CYCLIC REDUNDANCY CHECKING CIRCUIT         ABSTRACT OF THE DISCLOSURE A parallel cyclic redundancy checking circuit which determines the validity of digital, binary, cyclical data.  The parallel structure of this circuit enables it to check high frequency data.  Shift reg-isters store sequentially occurring parallel groups of data and a feedback network comprising exclusive-or gates provides a coding arrangement which produces a resultant data pattern to indicate the validity of the cyclical parallel input data.  Resultant data patterns are periodically stored in a random-access-memory which initializes the shift registers to pro-vide a time sharing operation.  A comparator detects invalid data by comparing the resultant patterns with expected values.

Abstract: "THERMAL STRESS RELIEF IN REFRIGERATORS"                 ABSTRACT OF THE DISCLOSURE        A refrigeration apparatus having a plastic cabinet liner defining a refrigerated space and including a generally planar wall is located within a cabinet and spaced therefrom to receive foamed-in-place insulation.  The planar wall of the liner has a first stress relief rib formed therein along with an interruption in the first stress relief rib.  A second stress relief rib is formed in the planar wall and spaced from the first stress relief rib and has an extent generally parallel to the first rib at least equal to the length of the interruption.  Thus, the first and second rib define a functionally continuous stress relief rib across the planar wall.

Abstract: ORGANOSOLV PROCESS FOR HYDROLYTIC DECOMPOSITION OF MIXED LIGNOCELLULOSIC AND STARCH MATERIALS            ABSTRACT OF THE DISCLOSURE      Comminuted cellulose and starch containing vegetable materials, which may or may not contain lignin, are partial-ly or totally hydrolyzed or saccharified by using an aqueous acetone solvent mixture containing catalytic amounts of acid-ic compounds and containing in excess of 70 per cent by volume of acetone and up to virtually anhydrous acetone.  The process is carried out at elevated reaction temperatures, preferably at 145°C to 230°C in a closed vessel for a limited period of time and then withdrawing the solution containing the dissolved sugars and lignin and rapidly cooling the solution such that the resultant dissolved sugars from the hydrolysis are not deg-raded into non-sugars.  The reaction conditions are selected in such a way that the polymeric carbohydrate materials and lignin if present are dissolved simultaneously and such that ninety percent of the available sugars in the unhydrolysed material become available as monomeric sugars.  Sugars, lignins and protein derived are recovered separately along with the solvent used.

Abstract: ABSTRACT OF THE DISCLOSURE           A servomotor speed control system includes a ROM table which stores only one minimum distance corres-ponding to each motor speed.  When the minimum distance corresponding to the current motor speed becomes shorter than the current distance from the current motor position to a positioning target point, the instructed speed is reduced to decelerate the servomotor rotation.  In a pre-ferred form, the unit of the distance is identical with an interval of a position indicating signal developed from a rotary encoder associated with the servomotor.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of, and apparatus for, encoding and decoding a sequence of data bytes to permit correction of bit errors occurring in one byte of the sequence, or two bytes providing that the two incorrect bytes can be identified (for example if the bytes show parity failure).  Each data byte of the sequence comprises data bits and one parity check bit.  To encode the sequence of data bytes two "Code C" code bytes are determined from the data bytes, according to predetermined relationships, the data bytes and code bytes together forming an encoded data block.  Also, there is provided a method of, and apparatus for, encoding and decoding a bundle of data blocks to permit correction of a number bit errors occurring in bytes of the bundle. (Conceptually, the bundle of data blocks comprises a stack of data blocks, one positioned under another to form a two dimensional array of bytes.)  Data block bundle encoding consists of separately encoding rows (i.e. horizontal encoding) and columns or pairs of columns (i.e. vertical encoding) of bytes of the use array with two "Code C" code bytes.

Abstract: ABSTRACT            The present invention relates to a measurement device for de-termining the degree of compaction of dam- and road-building material after the material has been compacted with a suitable compaction machine. The measurement device consists of a vibra-ting drum which is equipped with a transducer for generating signals while the drum is being run over the ground surface for which the degree of compaction is to be determined. In order to eliminate factors which impede evaluation of the signals emanat-ing from the signal transducers, the measurement device incorpor-ated in the drum is designed so that its contact surface with the ground surface is as restricted as possible. One method of achieving this is by reducing the width of the drum and/or shap-ing the casing surface of the drum in an arch in a plane paral-lel with the rotary axis of the drum.

An electronic digital display (16) relevant to a control setting for the remote instrument is arranged off the optical axis of microscope (10) and viewed by a convex mirror (20).  A folding mirror (21) directs diverging light from convex mirror (20) toward beam splitter (15), and a collimating lens (22) collimates the diverging light enroute from folding mirror (21) to beam splitter (15).  Collimated light from the lens is incident to beam splitter (15) to position an image of the digital display in a marginal region of the apparent field of one of the binoculars (12).
