Title: Sealing sleeve for electricity meters or similar apparatuses
Inventor: HEMMING BERNHARD DIPL ING
IPC: G01R11/02
Filed: 1982-09-03
Abstract: A sleeve is used for sealing electricity meters and similar apparatuses, in order to avoid the disadvantages of wire-lead seals. Said sleeve is pushed under the attachment screws of the housing caps without the screws having to be completely unscrewed. At the same time, the shaping of the sealing sleeve is selected such that security against rotation is provided when the attachment screw is tightened, in the case of virtually all electricity meters which were previously manufactured in the Federal Republic of Germany. The base area of the sleeve is constructed such that the sleeve can no longer be removed once the attachment screw has been tightened. The sleeve is closed by means of a clamping piece which, once it has been pressed on, can be removed again only by destroying it, and the attachment screw can no longer be turned. At the same time, the clamping piece is constructed such that displacement of the sealing sleeve in the tightened state is fundamentally prevented.

Title: Proportional pressure-relief valve with solenoid-operated pilot control
Inventor: BRUNNER RUDOLF
IPC: G05D16/20
Filed: 1983-08-05
Abstract: The invention relates to a proportional pressure-relief valve with solenoid-operated pilot control, having a valve element which is acted upon in the opening direction by the pressure to be limited and in the closing direction by an auxiliary pressure which is proportional to the current applied to the solenoid and can be regulated by a pilot valve actuated by the solenoid. In known valves of this type, the auxiliary pressure, which is controlled by the solenoid via a pilot pressure-relief valve, acts directly on the valve element. For this purpose, the main-pressure-relief valve requires a complicated type of construction. In addition, the pressure range in which the valve works is restricted in its size and its upper limit. According to the invention, this is avoided by a servo piston being provided which is in operative connection with the valve element and can be acted upon by the auxiliary pressure.
