Patent DE-3409981-A1 (DE)
Inventor: HOELZER HELMUT DIPL ING
IPC: F16J15/48
Filed: 1984-03-19
Abstract: A seal for a shaft relatively rotatable in an opening in a structure has concentric inner and outer rings. The outer ring is fixed across the opening and has an inwardly-open groove with axial boundary surfaces which converge toward each other outwardly from the axis of the rings. The inner ring is elastic and has two flanges flanking a midsection which receives the shaft for relative rotation therewith. The flanges slidingly bear elastically on the boundary surfaces to produce the seal. The midsection of the inner ring has a larger outside diameter than the inside diameter of the outer ring to prevent extruding the inner ring from the outer ring under rotation or a pressure differential across the seal.

Title: Air dehumidifier for transformers
Inventor: WANNER OSWALD
IPC: H01F27/14
Filed: 1984-04-06
Abstract: Such air dehumidifiers have a filling which absorbs water vapour and are blocked off from the environmental air by a closure which can easily be opened inwards and outwards. According to the invention, a soft-elastic membrane (10) which is clamped in in the space between two filters (8, 11 and 12) on their circumferential edge, has an incision (13) in its central area, which incision (13) ends on both sides in front of the clamped-in edge, and is used as a closure. Air dehumidifiers having this closure are particularly suitable for use on oil-cooled transformers for powers up to approximately 50 MVA, and are primarily distinguished by their long life which is ensured despite them being maintenance-free.

Title: Process and apparatus for automatically producing hollow building boards, in particular of door leaves
Inventor: ZOESCHINGER THEODOR
IPC: B27G11/00
Filed: 1984-09-12
Abstract: In order to carry out the production of hollow building boards (24) in accordance with German Offenlegungsschrift 3044039 at reasonable cost and with high output, the invention discloses a process in which the pressed boards (1), provided with a machined chamfer on one side, are simultaneously coated on the upper side with a dispersion adhesive (7) and on the underside with a conventional veneer adhesive (11). The coating of dispersion adhesive (7) is partially dried (13) or thermoactivated. Two pressed boards (1) treated in this way are then laid with the chamfered sides one on top of the other and combined with the outer layers (20) to form a board stack (19), which is subsequently pressed in a press (22). By virtue of the heat treatment (13) of the coating of dispersion adhesive (7), it requires about the same setting time as the coating of veneer adhesive (11), although the former is at a considerably greater distance from the outside of the board than the latter. <IMAGE>

Title: Integratable decoding circuit
Inventor: FUCHS HANS PETER DIPL PHYS
IPC: G11C8/10
Filed: 1985-09-20
Abstract: An integratable decoding circuit to decode information which is represented by input signals (A1, A2, An; /A1, /A2, /An) is presented. It is made in CMOS technology, with n transistors of one channel type (M1, M2, Mn), and n transistors of the other channel type (T1, T2, Tn). In operation, its decoder output (DA) at every moment within a clock period (TP) is at a defined signal level (L, H). There is thus no pre-charging and then de-energising of a pre-charging transistor, which would result in floating of the output in the unselected state. The decoding circuit is particularly suitable for use in integrated semiconductor memories. <IMAGE>

Patent DE-3606780-A1 (DE)
Title: Method of serial data transmission between computers, and device to monitor this data transmission
Inventor: SCHMITT RALPH
IPC: G05B19/406
Filed: 1986-02-28
Abstract: In data transmission between computers, particularly for process control of machine tools, control characters and data characters are transmitted using only ASCII code characters which can be displayed on a terminal, and each character which is transmitted as a data byte by the transmitter is echoed back from the receiver to the transmitter, and triggers the transmission of the next character. This makes synchronisation in time particularly simple, and because of the echo, checking the data transmission is particularly simple. The characters which are transmitted by the transmitter are in upper case, and the characters which are echoed back are in lower case. So that they can be kept apart easily, most of the characters which are used are letters. By this method, it is particularly easy to monitor the data transmission using a data recording device which can be connected to the data lines, in parallel, via electronic decoupling elements. The system is completely unaffected, and can continue to operate in real time. By using a memory as the data recording device, the data transmission can be monitored without a monitoring person being permanently present, and even a non-specialist can manage to connect such a data recording device. The memory can be sent back to the machine manufacturer after an error occurs, and can ... Original abstract incomplete. <IMAGE>

Title: Device for reversing the polarity of the biological radiations of liquids
Inventor: FENEBERG WILHELM
IPC: C02F1/48
Filed: 1986-03-03
Abstract: The invention relates to a device for reversing the polarity of the biological radiations of liquids, such as water, milk and wine, for which it is characterising that the device comprises a spiral (1) which is arranged essentially concentrically to the liquid jet or stream (4). The spiral (1) is fabricated from metal, preferably from copper and, at least in part, can be provided with a coating. In addition, the spiral (1) can, at least in part, be constructed as a cone, it being constructed in strength and number of windings in relation to the intensity to be achieved. The device according to the invention provides the advantage that the water flowing from a pipe cock or tap, passed through the spiral, receives a spin which, together with the friction of the liquid on the spiral, reverses the polarity of the water, as a result of which a biologically active water rotating clockwise is obtained. <IMAGE>

Title: Process and device for producing a heat-insulating building block (brick)
Inventor: DENNERT HEINZ
IPC: B28B13/06
Filed: 1986-04-01
Abstract: The invention relates to a process for producing a heat-insulating building block (brick) (12), in particular a lightweight concrete or lime-sand brick. From a supply device or charging device (bunker 1, charging car 3), a mould cavity (13) of a mould (9) open at least at the top is filled from the top with a basic mixture (2). By means of a compaction plunger (16, 16') and a countersupport means (support 14, countersupport plunger 26), the basic mixture (2) is compacted under the effect of pressure to form the actual building block (12). The process is characterised in that the basic mixture (2) is introduced into the mould cavity (13) with the assistance of a compressed-air stream acting in the discharge opening (8) in the charging direction (18). By this means, even thin-walled material webs (29) can be formed in the building block (12). A moulding press operating according to this process is also described in greater detail. <IMAGE>

Title: Vane cell pump
Inventor: PFALZGRAF HELMUT
IPC: F04C2/344
Filed: 1986-04-26
Abstract: A vane cell pump (10) is proposed, which simultaneously works as a vent valve at standstill or low speed of the rotor (16). The cross-section of the inner space (32) of the vane cell pumps (10), which receives a rotor (16), has a cross-section which deviates from that of the rotor (16) in such a manner that a sudden spacing change occurs between rotor outer wall and housing inner wall (14). As a result of this, vanes (26) arranged in slots (18, 20, 22, 24) come in a delayed manner into interaction with the inner wall (14) so that a continuous connection between the working inlet and outlet (28, 30) of the vane cell pump (10) can be formed. <IMAGE>
