Abstract: Durch die Bewehrung soll eine verbesserte Feinrissverteilung und höhere Festigkeit des bewehrten Bauteiles erzielt werden, indem ein Zusammenballen von Einzelfasern verhindert und eine gleichmässige Verteilung derselben selbst über den Querschnitt des Bauteils erzielt wird. Die Einzelfasern werden zusammen mit einem Fasernetz und den Zuschlagstoffen in die Mischmaschine eingebracht. Vor dem Einbringen weist das Fasernetz eine geraffte, schnurförmige Form auf und verteilt sich während des Mischens selbst. Es werden Fasern unterschiedlicher Länge und aus unterschiedlichen Stoffen verwendet. Dabei sind die Relationsmengen bezüglich der Faserlänge und bezüglich der E-module der Fasern derart gewählt, dass sie der Gesetzmässigkeit folgen, die durch die Siebkurve bezüglich der Korngrössen der Zuschlagstoffe zur Erzeugung der optimalen relativen Korngrössenverteilung im Beton gegeben ist.

Abstract: An improvement to the character selection control system disclosed in US Patent 4 094 937 is described where a biasing spring (90) is urgingly engaged with the rack (56) of a rack and pinion arrangement used to rotate the type element (60), and thereby places a biasing load on the system, through link (54), such that the force between the slider block (118) of the character selection system and the stop member engaged by the slider block (118) will be reliably increased, while at the same time, prevent-, ing an increase in the drive requirements of the drive motor (8) for the system. This spring biasing has a secondary benefit in that it tends to uniformly cause consolidation of all tolerances and relative movement in the system due to wear and thus stabilize the system for improved detenting of the type element (60).

Abstract: The collimator assembly comprises a collimator shielding block for blocking undesired X-rays and an insert piece inserted into the shielding block. The insert piece, which is made of a material of high atomic number, has an inner conical surface which defines the X-ray cone transmitting the insert piece and therefore the maximum field size which can be obtained for medical treatment. In order to supply different maximum field sizes, there are provided means for easily interchanging the insert in the collimator shielding block with another insert having a different interior conical dimension. By using inserts of different cone angles, which can easily be inserted into the shielding block, for instance by means of a screw thread from below the shielding block, moribd tissues of different sizes can be treated while the surrounding healthy tissue is fully protected.

Abstract: Zum Einschalten eines Leistungs-Feldeffekt-Schalttransistors (T1) wird die Gate-Source-Kapazität durch Zuschalten eines Kondensators (C1) über einen ersten Transistor (T2, T3) aufgeladen. Zum Ausschalten des Leistungs-Feldeffekt-Schalttransistors (T1) wird die Gate-Source-Kapazität durch Einschalten eines zweiten Transistors (T3, T2) entladen. Damit erfolgt sowohl der Aufladevorgang als auch der Entladevorgang niederohmig, so daß er jeweils in kurzer Zeit ablauft. Infolgedessen werden die Schaltzeiten und somit auch Ein- bzw. Ausschaltverluste des Leistungs-Feldeffekt-Schalttransistors (T1) gering gehalten. Dabei ist weder eine gesonderte Hilfsspannungsquelle erforderlich, noch werden induktive Elemente benötigt.

Abstract: A wire electrode pull-up mechanism in a wire-cut electric discharge machine having an energized wire electrode stretched between upper and lower guides for machining a workpiece by means of an electric discharge, wherein the wire electrode pull-up mechanism pulls up a wire electrode which has been passed through a bore in the workpiece until the upper end of the wire electrode protrudes from the upper side of the workpiece, and includes a gripping member (110) for gripping the wire electrode. The gripping member (110) includes an arm (110b) having a bearing wall (110j) at the distal end thereof, a clamping member (110c) pivotally provided on the arm (110b) and having a cam body (110h) and a restraining portion (110g) for abutting against the bearing wall (110j) of the arm (110b), a spring member (110i) for urging the clamping member (110c) in such a manner that the restraining portion (110g) thereof abuts against the bearing wall (110j), and an operating member (110d) pivotally provided on the arm (110b) and having a cam operating portion (110p) abutting against the cam body (110h) of the clamping member (11 Oc) for pivoting the clamping member (110c), the operating member (110d) being pivoted owing to pressured contact with the upper surface of the workpiece when the gripping member (110) is lowered into abutting contact with the upper surface of the workpiece by the drive member. The clamping member (110c) is pivoted by the cam operating portion (110p) as the operating member (110d) abuts against the workpiece, in such a manner that the clamping member (110c) causes a gap to be formed between the restraining portion (110g) and the bearing wall (110j), and the operating member (110d) separates from the workpiece when the arm (110b) is raised, whereby the clamping member (110c) is pivoted by the spring member (110i) so that the upper end of the wire electrode, inserted into the gap, is retained between the restraining portion (110g) of the clamping member (110c) and the bearing wall (110j) of the arm (110b).

Abstract: In an apparatus having a record mode for recording video or other information signals in successive parallel information tracks on a record tape by means of a plurality of rotary heads repeatedly scanning across said tape and having respective gaps with different azimuth angles, and in which the apparatus is changeable to a playback mode for causing each of said heads to provide a respective output when it is scanning an information track in which information signals have been previously recorded by a head with a gap having the same azimuth angle; clogging of one or more of the head gaps which would prevent further recording is detected, in the playback mode, by switching from one to another of the outputs of the heads during each period required forthe scanning of the tape by each of the heads, detecting the levels of the head outputs during such switching therebetween, and operating a clog indicator when the detected levels of the head outputs are insufficient during the scanning of the tape by each of the heads. In order to avoid a false clog indication, the operation of the clog indicator is inhibited when the usual fixed head does not reproduce control signals in the playback mode, for example, as when there has been no previous recording of information signals on the record tape.
