Abstract: ABSTRACT OF THE DISCLOSURE         In the processing of a wide-band, analog ultrasonic echo signals of a large dynamic range, and especially echo sig-nals generated in the ultrasonic testing of material, signal distortions must be avoided in order to enable an exact analy-sis of fault signals and a good reproducibility.  To accomplish this object, the signals generated by an ultrasonic detector are supplied to a linear preamplifier generating analog output signals.  The analog output signals are fed to an analog-to-digital converter, which converts them directly and in parallel way into logarithmically encoded  digital signals.  In these digital signals one bit is assigned to  the polarity of the in-put signals while the other bits correspond to the respective level of the ultrasonic echo signal.  The analog-to-digital con-verter is composed of a plurality of parallel-connected units, which together define a logarithmic characteristic curve for positive and negative output signals of the preamplifier.  The digital signals are supplied to an evaluation unit connected to the analog-to-digital converter.  In this manner, notwithstand-ing the wide-band ultrasonic echo signals of large dynamic range, substantially distortionless processing is achieved.

Abstract: ABSTRACT         This specification discloses a locking structure for a pair of matable electrical connectors. The locking structure includes a latch assembly formed on one of the connectors and a mating ramp.  The latch assembly includes integral locking and lever arms which coact with the ramp to permit locking and unlocking of the connectors.  During locking of the connectors, the locking arm rides up the ramp member to insure proper mating of the connectors and then down a rear, vertical wall.  During unlocking of the connectors, the lever arm uses the ramp as fulcrum to raise the locking arm clear of the rear wall permitting movement of the locking arm over the ramp so that the connectors are easily unmated.  The lever arm and the latch arm are connected at only one end thereby forming an elongated, generally V-shaped opening.  This entrance is partially closed by a projecting guard so that wires cannot enter between the lever arm and the locking arm and get stuck.

Abstract: TITLE OF THE INVENTION            ACTUATION DEVICE FOR TWO TYPEWRITER FUNCTIONS            INVENTORS            Franco VALLE, an Italian subject residing at Via Fratelli Rosselli, 3 10015 Ivrea (Turin) Italy, and Piero MUSSO, an Italian subject residing at Via Favero, 3 10015 Ivrea    (Turin) Italy.           ABSTRACT OF THE DISCLOSURE          A cartridge    for a typing ribbon    and spools for a correcting ribbon    are mounted on a common frame which can tilt about a spindle   .  In a lowered position of the frame the typing line behind a daisy wheel    is visible.  The frame is raised by a first stroke to the position shown to dispose the typing ribbon over the typing point on the platen   .  A longer stroke raises the correcting ribbon    to the typing point and this longer stroke also actuates an automatic ratchet wheel and pawl type of feed mechanism for the correcting ribbon.  The two strokes of the frame are controlled by a disc comprising two cam tracks with a common part   and separate parts           having different degrees of eccentricity relative to the common part.  The grooved cam tracks are so shaped that a follower pin   on an arm    depending from the frame enters the radially inner track    when the disc    is rotated clockwise by a reversible electric motor, thereby to raise the frame by the smaller amount, whereas it enters the radially outer track  in the case of anticlockwise rotation.    The disc also carries a frontal cam which operates a ribbon feed mechanism for the ribbon in  a  container  of the cartridge.

Abstract: ABSTRACT OF THE DISCLOSURE             A high potency rennet substitute from seals is provided herein. Such extract closely matches the characteristics of the calf rennet, namely, (1) is coagulates milk over a wide range from 6.0 to 6.8, (2) it has a high ratio of milk clotting to proteolytic activity, (3) it has limited action on milk proteins, (4) it has limited substrates specificity as evidenced by its relative inability to inactivate ribonuclease - a test used to distin-guish renning from other proteolytic enzymes; and (5) it results in a desir-able aged flavor in cheddar cheese. This crude preparation of seal pro-teolytic enzyme precursors is composed of 4 components, the major two of which have molecular weights of 28,500 and 40,000 Daltons as determined by gel filtration on a SEPHADEX G-100 (Trade Mark for a polysacchoride dextran in which the functional ionic groups are linked to the glucose units of the polysacchoride chains by ether exchanges) column and 40,000 and 50,000 Daltons by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate.  The crude active preparation has a pH optimum of 2.6 for hemoglobin. hydrolysis at 30°C. Results of an isoelectric point determination revealed that the four components of the active preparation have isoelectric points of 4.9, 4.3, 3.8 and 3.4.

Abstract: ABSTRACT OF THE DISCLOSURE A subscriber station functioning as a concentrator is connected to subscribers and is connected via trunk lines to a centrally placed transit exchange establishing connections, by reason of a given command, between a source sending special information and a trunk line pointed out as being idle.  The subscriber station includes a trunk line economizing apparatus investigating each time a subscriber calls the source whether one of the trunk lines is already connected to the source.  If no such connection is determined, the source and the calling subscriber are conven-tionally connected to a trunk line indicated as being idle, the number of this line being intermediately stored in a memory unit associated with the economizing apparatus.  If it is de-termined on investigation that the special information is already being transferred to the subscriber station, the sub-scriber calling the source is connected to the trunk line whose number is intermediately stored in the memory unit.  The economizing apparatus includes a circuit for cancelling the intermediate storage when the special information is no longer received by any of the subscribers.  Independent of the number of subscribers receiving the special information, only a single trunk line is taken into use, and the central transit exchange is only loaded with a single connection establishment.

Abstract: ABSTRACT OF THE DISCLOSURE        The disclosure describes a horizontal slab gel electrophoresis apparatus.  The latter consists of two spaced apart vessels which are each adapted to contain a running buffer.  Each vessel is provided with an electrode for connect-ion to a suitable power supply.  At least one horizontal plate to contain a slab gel is disposed in bridging fashion over the first and second spaced apart vessels.  Capillary contact should be established between one end of the slab gel and the running buffer which is present in the first vessel and also between the other end of the slab gel and the running buffer which is present in the second vessel.  The method involves using this apparatus by adding a solution of a mixture of mole-cules of mixed molecular weights, such as DNA to wells formed in a horizontal slab gel after which the gel is treated by electrophoresis to produce localized bands each being characteristic of a specific molecular weight.  This invention has the great advantage of enabling the electrophoresis to be carried out with a plurality of horizontal agarose slab gels while using only one power supply.
