Patent DE-3211765-A1 (DE)
Title: Sleeve and sealing ring for a pipe plug connection
Inventor: WOLF FRANZ-JOSEF
IPC: F16L17/035
Filed: 1982-03-30
Abstract: A sleeve and sealing ring for retention in an annular groove which is constructed in the collar region of the sleeve for a pipe plug connection are characterised in that the lip-like sealing sections of the sealing ring, which rest on the outer jacket of the tip end to be sealed, have a radial width which is less than the radius of curvature of a convex annular section which lies opposite the angle enclosed by the two annular surfaces. In consequence, the torsional sealing ring, whose functional principle is known per se, is provided with an essentially bean-shaped or cardioid cord profile which makes possible a high configuration stability and sealing of the pipe plug connection, with a short axial construction, without additional reinforcing measures.

Inventor: EBERHARDT WOLFGANG DIPL ING
IPC: H01H33/12
Filed: 1982-09-24
Abstract: A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece. The pieces are configured and arranged relative to one another so that during the closing of the switch the countercontacts contact the contacts after the primary contact pieces are moved to the second position and before they are moved to the third position, and during the opening of the switch the countercontacts separate from the contacts after the primary contact pieces are moved to the second position and before they are moved to the first position.
Patent DE-3246723-A1 (DE)
Title: Edge beam for swimming pools
Inventor: BROSSARD PHILIPPE DE
IPC: E04H4/12
Filed: 1982-12-17
Abstract: The invention, best seen in Fig. 1, relates to an edge beam as an overflow for swimming pools, which can lie approximately flush with the surface of the water and forms on its upper side a breakwater plane which is slightly inclined towards the surface of the water and of which the ridge drops into a return channel. To prevent the most frequently occurring small waves from reaching the breakwater plane, the latter is preceded by a collecting groove in the edge beam, which communicates with the return channel and runs close to the pool-side edge of the edge beam. As a result, even when the swimming pool is in use the aesthetically pleasing impression of a smooth, regular boundary approximately level with the surface of the water is maintained. <IMAGE>

Title: Heat-insulating and sealing material based on polyurethane or other plastic foam systems with admixtures of radiation-impervious material for use in all nuclear areas
Inventor: SIEPMANN ROLF DIPL PHYS DR
IPC: C04B26/02
Filed: 1983-01-11
Abstract: Heat-insulating and sealing material based on polyurethane or other plastic foam systems, with admixtures of radiation-impervious material fluid to the fluid components, for use in all nuclear areas and their surroundings. The substantially lower density than in traditional anti-radiation materials permits cost-effective methods of construction in anti-radiation areas in the case of existing objects or objects still to be erected. Depending on the method of manufacture, this radiation protection can be used in the form of shaped parts, plates, webs or it can be "endless". The dimensioning and chemical composition of the material depend on the nature of the problem in question and on the radiation exposure or contamination in the intended area of use.

Title: Switch-mode power supply
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M3/28
Filed: 1983-10-07
Abstract: In this switched-mode power supply (two-transistor forward converter or flyback converter) for supplying power to DC loads, such as electronic apparatuses and systems, the primary winding (10) of a medium-frequency transformer (9) is connected to a DC voltage source (1) via two electronic switches (4, 7), which are to be driven in synchronism, are preferably power switching transistors and are operated in the switching mode. The first electronic switch (4) is in this case driven directly by means of a control and regulating device (6). The transformer (9) is provided with a control winding (11), for driving the second electronic switch (7) indirectly by means of the first switch. The primary winding (10) has a centre tap to which half the input DC voltage, which is obtained via a resistor/capacitor circuit (14, 15, 16), is connected via a diode (13). <IMAGE>

Title: Bottom gate valve of a shielded transport flask for radioactive materials
Inventor: BAETKE KLAUS
IPC: G21F5/12
Filed: 1983-10-27
Abstract: A bottom gate valve of a shielded transport flask for drums with radioactive contents, which is intended for sealing the bottom opening and which consists of a rectangular shielding member which can be moved to and fro in the base part of the flask on a rail, can be moved out of a side opening of the flask and can be arrested therein by means of blocking bolts which act perpendicular to the direction of movement. The aim is to provide for this bottom gate valve a novel locking device in which the time during which the personnel needs to be present in the vicinity of the transport flask in order to operate the locking bolts can be substantially shortened. This is achieved by means of a mechanism with which all the locking bolts can be moved simultaneously to open or close a single operating point. All the components of the lock are integrated in the gate member and form an internal lock. A drive bolt by means of which in each case two locking bolts can be moved in and out via a connecting link guide is installed for this purpose in the gate member in the longitudinal direction. The actuation of all the locking bolts is performed from outside by a simple sliding to and fro of the drive bolt, whose actuating handle can be sealed off on the outside by a lock for safety reasons. The internal lock also facilitates the construction of transport flasks with reinforced shielding which have a base part with a lead shield ... Original abstract incomplete.
Patent DE-3345848-A1 (DE)
Title: Calorimeter
Inventor: MUELLER ELMAR DIPL ING
IPC: G01K17/14
Filed: 1983-12-19
Abstract: The invention relates to a calorimeter which is constructed such that it can operate independently of a supply of electricity. According to the invention, two expansion elements (5 and 6) are provided, which have the same coefficient of expansion and are connected via in each case one heat pipe (7, 8) to the feed (2) or drain (3) of a thermal load through which a flowing medium flows. A change in length arising given different temperatures of the flowing medium in the feed (2) and drain (3) is proportional to the temperature difference between the medium in the feed (2) and the medium in the drain (3). This temperature difference T is transmitted to a counter (25) by means of a transmission lever (10) and a mechanism (15, 16, 17, 21, 23, 24). The mechanism (15, 16, 17, 21, 23, 24) is connected to a drive (28) which is actuated by a volumetric meter (32) which is arranged in the feed (2). The rotational motion emanating from the torque shaft (31) of the volumetric meter (32) is transmitted to the mechanism (15, 16, 17, 21, 23, 24, 26) via a linkage (29) and a bevel gear (27). <IMAGE>
