Patent DE-9108589-U1 (DE)
IPC: H01H33/12
Filed: 1991-07-09
Abstract: An isolating switch is to be adapted to the heavy currents occurring during busbar changes at low operating voltages. To this end, an auxiliary contact pin (3), which is located in a counter-contact (2) in the known manner and acts as a preliminary contact, is fitted with an auxiliary sliding contact (11). The auxiliary contact pin (3) runs off this auxiliary sliding contact (11) after the counter-contact member has made contact. Thus the rated current is conducted solely along the main current track. (The auxiliary contact pin runs off the auxiliary sliding contact.)
Patent DE-9115956-U1 (DE)
IPC: F16L41/08
Filed: 1991-12-21
Abstract: The invention relates to a device for the watertight connection of plastic sewage pipes to subterranean structures. This connection is preferably used in sewage system inspection shafts. The device consists of a shaft lining which is introduced into the shaft wall directly above the shaft base and has an inwardly open, circumferential central groove for holding a sealing element. In this case, shaft lining parts run outwards from the central groove with their unobstructed width becoming increasingly larger. The invention is seen in the fact that the shaft lining part (2) facing the shaft base (61) is constructed cylindrically corresponding to the external dimensions of the plastic sewage pipe (7) which is to be pushed in. At its free end, the shaft lining part (2) has a stop (5) whose circumferential height largely corresponds to the wall thickness of the plastic sewage pipe (7). <IMAGE>

Title: Chiusura di sicurezza a bilanciere oscillante e con dente di arresto, per bracciale anulare rigido in metallo prezioso o non
IPC: A44C/
Filed: 1992-02-28
Abstract: Il bracciale in questione è costituito da due archi semicircolari rigidi, incernierati ad una estremità e comportanti una chiusura di sicurezza particolarmente efficace.-Essa è rappresentata da un piccolo bilanciere rigido oscillante, fisso ad uno degli archi del bracciale, munito ad una estremità di un dente che, nella fase di chiusura del bracciale, si impegna in un foro esistente in una appendice solidale con l'altro arco semicircolare.- L'apertura del bracciale si ottiene premendo sul bilanciere alla estremità opposta al dente di arresto, vincendo così la forza di una adeguata molla antagonista.
