Patent DE-3703799-A1 (DE)
Title: 3-dimensional rotating toy
Inventor: LIEKE MICHAEL
IPC: A63F9/08
Filed: 1987-02-07
Abstract: 3-dimensional rotating toys have rotating bodies that can be twisted about axes of rotation. These axes of rotation preferably extend through the centre of the complete body. The rotating bodies can be twisted - depending on the version - in layers or shells. "Templates" are used to twist the rotating bodies. Pin-like projections can be reversibly sunk into associated recesses in the rotating bodies, preferably in a stationary version and against spring pressure. On the "outside" the rotating bodies are held by a transparent layer (envelope, shell), which in one embodiment has recesses in the region of the axes of rotation for the purposes of twisting the rotating bodies with the appropriate template. The 3-dimensional version preferably has a substantially spherical shape. The axes of rotation are preferably located relative to each other like the axes extending through the angles of regular polyhedrons. Deviations from this are comparable and are provided as an alternative embodiment. For practical playing use, the rotating bodies are so marked that each of the rotating bodies can only adopt a very specific defined position in the ordered complete combination; by alternating twisting of the rotating bodies about different axes of rotation, this order is destroyed. To rediscover the original arrangement requires a certain intelligence.
Patent DE-3708768-A1 (DE)
Inventor: VOGELSANG HORST
IPC: F16L47/06
Filed: 1987-03-18
Abstract: Pipe connector for plastic pipes made of a thermoplastic material, especially for cable ducts and pressure pipes with a plug-in end (1), a collar (2) and a sealing ring (4), of natural or artificial elastomers, which is inserted loosely into a retaining groove (3) of the collar (2). The retaining groove (3) has a trapezoidal cross- section, with a flank (5) on the plug-in side and an opposing flank (6), and makes a transition into a closed sealing chamber (7). The sealing ring (4) consists of a single-piece partial retaining ring piece (11), matched to the trapezoidal cross-section with abutting surfaces (8, 9, 10), and a funnel-shaped partial sealing lip piece (12, 13) which is drawn over the latter. The partial retaining ring piece (11) is inserted in the retaining groove (3). The partial sealing lip piece (12, 13) can be pressed through the insertion end (1) on insertion into the sealing chamber (7). The insertion end (1) has a front conical surface (15) on the outside. The partial retaining ring piece (11) is provided internally with a circumferential compression rib (16) which has a triangular rib cross-section. The compression rib (16) is arranged behind the surface centre point (FM) of the trapezoidal cross-section of the retaining groove (3). The opposing flank (6) of the retaining groove (3) and the associated abutting surface (10) of the partial retaining ring piece (11) form an angle (W1), with respect to a pipe connector radius (R), which is smaller than the self-locking angle (WdS), so that self-locking occurs. The angle (W2), related to a pipe connector radius (R), of the cross-sectional surface (17) on the plug-in side of the compression rib (16), which comes into contact with the conical surface of the plug-in end when the latter is inserted, is greater than the self-locking angle (WdS), so that self-locking does not occur. <IMAGE>

Title: Method for operating a belt-grinding machine, and belt-grinding machine
Inventor: RENARDY GUENTHER DIPL ING
IPC: B24B21/08
Filed: 1987-05-20
Abstract: The belt-grinding machine is equipped with a driven conveying belt (1), which moves the workpieces to be ground, and with a grinding belt (3) which runs round endlessly above the conveying belt transversely or longitudinally to the direction of movement of the workpiece. The grinding belt is pressed against the workpiece (2) by a multiplicity of pressure elements (6) arranged transversely to the direction of movement of the workpiece, by means of adjusting motors assigned to said pressure elements, the adjusting motors being actuated separately and independently of one another. Arranged between each pressure element (6) and its assigned adjusting motor (10) is a pressure cell (7) which, in practice determines the grinding pressure (actual value). In a controller (11) this actual value is compared with a preset desired value and in the event of deviation between actual and desired value a correction of the pressure element is carried out with the aid of the adjusting motor (10). It is thus possible to detect even small thickness tolerances in the workpiece itself without the use of mechanical scanning equipment and thus to ensure a uniform grinding pressure, so that thicker points on the workpiece are not more intensively ground than thinner points. <IMAGE>
Patent DE-3724245-A1 (DE)
Title: Protective diaphragms for pipelines
Inventor: SCHUBERT WERNER DR MED
IPC: F16L55/052
Filed: 1987-07-22
Abstract: High-energy systems, such as those using nuclear energy or microwaves, necessitate the use of efficient protective means which should expediently be used in a graduated manner. Pressure-surge absorption in coupled-on supplementary pipes, in the interior system as it were, is also possible through relatively large gas chambers if said gas chambers are separated by protective diaphragms from a medium which is exposed to pressure surges. It is only when a relatively high pressure surge takes place in the actual case of disruption, that elongate slots in pipelines/parts of the pipeline, likewise covered by protective diaphragms, or similar devices can be brought into play in the manner of rupture discs.

Patent DE-3735645-A1 (DE)
Title: Switching valve
Inventor: ZAUNER FRIEDRICH DIPL ING
IPC: F16K47/00
Filed: 1987-10-21
Abstract: In a mechanically actuable switching valve for allowing and shutting off the flow of a pressure medium, particularly for allowing the flow of cooling fluid to the bit-associated nozzles of a cutting head, in which the cooling fluid is fed to the nozzles as a function of the axial displacement of the bit, the valve tappet (1) dips into a space (5) filled with pressure medium and the valve shut-off member is designed as a slide (9), one end face (12) of which likewise dips into the space (5) filled with pressure medium. When the valve is closed, this space (5) filled with pressure medium is open via a throttle hole (10) and connected to a pressure-medium source. After or during the opening of the valve, the slide (9) slides over the throttle hole (10). This prevents any further throttled outflow of pressure medium from the space (5) and the further opening movement of the slide (9) takes place more rapidly. Like the initially damped opening movement, the movement of the slide (9) during the closure of the valve is damped in the last part of its travel. <IMAGE>

Title: Method for the simultaneous measurement of the turbidity and the particle concentration of liquids
Inventor: OTTO MATTHIAS PROF DR SC NAT
IPC: G01N21/53
Filed: 1988-06-25
Abstract: The method relates to the field of the monitoring and deliberate influencing of natural and artificial stretches of water as well as of particle-laden liquids. For the simultaneous measurement both of the turbidity over the complete turbidity range and also of the particle concentration whilst ensuring relatively small measuring volumes, the turbidity channel is acted upon by narrow-band intensity-modulated alternating light and the concentration channel is acted upon by direct light of constant, broad-band light intensity in a turbid and particle-laden liquid via an optical measuring channel at two optically different receiver channels. In this case, the turbidity channel consists of a large-area bundle of optical fibres and the concentration canal is formed by a single optical fibre. The alternating and direct light pass through the measuring space as a parallel bundle of rays to the receiver channels, via an optical measuring channel. The corresponding measuring signals are converted opto- electronically and displayed.
Patent DE-3821935-A1 (DE)
Title: Internal combustion engine with valve timing gear
Inventor: KOROSTENSKI ERWIN DIPL ING
IPC: F02D13/02
Filed: 1988-06-29
Abstract: In an internal combustion engine with valve timing gear with two exhaust ports per cylinder and with an exhaust turbocharger, the first exhaust ports of all cylinders are connected to the turbine inlet and the second exhaust ports of all cylinders to a bypass line bypassing the turbine. The second exhaust valves are opened later than the first exhaust valves, so that the greater portion of the exhaust gas energy can be used to drive the exhaust gas turbine. On opening of the second exhaust valves, a portion of the exhaust gas mass flow is led past the exhaust gas turbine, thereby limiting the charge pressure. The second exhaust valves are preferably provided with a variable valve timing gear, which on attainment of a certain charge pressure shifts the opening point towards earlier opening and/or increases the valve lift.

Patent DE-3829188-A1 (DE)
Title: Moulding method and device
Inventor: WEIMANN WENDELIN
IPC: B22D47/02
Filed: 1988-08-29
Abstract: The invention relates to a moulding method and a moulding device in which, to save on mould boxes, the cooling section ajoining the casting machine is divided into a primary and a secondary cooling section. The primary cooling section is just long enough to ensure that the castings situated in the mould have a sufficiently strong solidified outer shell for boxless transport along the secondary cooling section. At the end of the primary cooling section, the moulds contained in the castings are ejected from the mould boxes as mouldings and guided along the secondary cooling section, supporting each other as they move along, while the mould boxes are recycled.
Patent DE-3831672-A1 (DE)
Title: Door stop, in particular suitable against the undesired slamming-shut of entry doors to detached houses and flats
Inventor: WALLUT WALDEMAR
IPC: E05F5/04
Filed: 1988-09-17
Abstract: The door stop is screwed on the door frame or the steel case. If the pivotable rubber damper is released from the retaining means, the rubber damper comes to bear against the door edge by virtue of the slight helical-spring stressing from the inside; if the door is opened from the inside, the rubber damper slides past the door edge and comes to bear against the door frame or the steel case. If the door is going to slam shut, the inner rebate of the door strikes against the soft rubber damper: consequently, the door lock cannot latch in and the person standing outside is not shut out. When one leaves the flat, one presses the pivotable rubber damper into the retaining means, counter to the helical-spring stressing, and the door lock of the door can latch in and be locked from the outside.

Title: Method for recharging batteries of an open type and of a sealed type, as well as a charger for carrying out the method
IPC: G01R31/36
Filed: 1988-10-06
Abstract: The invention relates to a method for recharging batteries of an open type and of a sealed type, as well as a charger for carrying out the method. A constant voltage is applied to the battery for a predetermined maximum time period. A check is carried out during this period to determine whether a minimum charging current of predetermined magnitude is flowing. If the charging current is not reached, the charging process is interrupted and the battery separated out. When the minimum charging current is first exceeded, a constant charging current is applied to the battery until a predetermined nominal battery voltage level is reached. A constant voltage is then applied to the battery until a predetermined charging time or a predetermined residual charging current is reached.
