Abstract: Ствольная накладка содержит зажим с противоположными наклонными поверхностями, клинья, входящие в соединение с наклонными поверхностями, и крепления, проходящие через клинья и противоположные стороны ствольной накладки. Поворот креплений прижимает клинья к наклонным поверхностям, чтобы прижимать зажим и соответствующий зажимной элемент к стволу и прижимать к нему ствольную накладку. Зажим и клинья предотвращают поворот ствольной накладки и обеспечивают параллельное восходящее и нисходящее движение. Крепление может проходить через канал клина без вхождения в соединение с этим каналом клина, в то время как другое крепление может иметь резьбовое соединение с другим каналом клина для того же клина, для обеспечения горизонтального движения клина посредством поворота крепления. Технический результат – уменьшение времени установки ствольной накладки без применения тисков и инструментов, отсутствие контакта с газовой трубкой, возможность установки на оружие разного типа, предотвращение поворота или перемещения ствольной накладки и любых соответствующих принадлежностей по отношению к остальным частям огнестрельного оружия. 3 н. и 17 з.п. ф-лы, 7 ил.

Granted: 1983-12-01
Abstract: Die Erfindung bezieht sich auf eine Schaltungsanordnung mit steuerbaren Halbleiterventilen, bei der sowohl das Ein- als auch das Ausschalten mit einem kurzzeitigen Steuerimpuls erfolgt. Im Leistungsstrompfad ist die Parallelschaltung eines Thyristors und eines Transistors vorgesehen. Der Thyristor dient zum Einschalten und zum Fuehren des Stromes, waehrend der Transistor durch kurzzeitige Uebernahme des Thyristorstromes den Ausschaltvorgang der Schaltungsanordnung besorgt. Die Vorteile bestehen darin, dass Kommutierungsanordnungen wie bei selbstgefuehrten Wechselrichtern nicht erforderlich sind, und dass zum anderen der Steuerleistungsbedarf gemessen an dem fuer Transistoren gering ist. Ausserdem ist der Transistor hoeher ausnutzbar, da in ihm weder die Einschalt- noch die Durchlassverluste entstehen. Hierdurch ist auch die Gefahr gegenueber einem zweiten Durchbruch geringer. Die Schaltungsanordnung ist bis zu beliebig niedrigen Betriebsfrequenzen zu  betreiben, die obere Frequenzgrenze haengt von der Freiwerdezeit der verwendeten Thyristoren ab.                                                                                                                                                                                                                                                                                                                                                                                                                                           ...U.S.W
