Title: Heat sink for liquid-cooling power semiconductor devices
Inventor: VOGEL XAVER
IPC: H01L23/473
Filed: 1982-06-07
Abstract: The semiconductor contact surfaces (2) of the heat sink (1) for liquid-cooling power semiconductor devices has cooling slots (3) which are connected to a connecting channel (7) for supplying the cooling liquid. The effect of this solution is that the cooling liquid is able to cool the surface of the semiconductor device to be cooled partly by direct contact, the heat sink (1), which touches the surface to be cooled in the unslotted subsurfaces between the cooling slots (3) and absorbs some of the heat loss, being cooled at the same time. Direct contact of the cooling liquid eliminates the heat conduction transfer resistance in the cooling slots (3), thereby substantially improving the cooling action of the cooling liquid. <IMAGE>

Title: Rocking device
Inventor: EWRINGMANN ULRICH
IPC: A63G15/00
Filed: 1982-10-04
Abstract: A rocking device (1), in particular for children, is described which has a rocker (3), by means of which a vertical rocking plane is defined which also forms a plane of symmetry for the rocking device (1), and at least one roller body (13) arranged eccentrically. In order to allow forward movement with the device at the same time in addition to the rocking, the device has a roller body (13), which is mounted eccentrically and is, in particular, wheel-shaped, and two further, in particular cylindrical roller bodies (20, 21), said roller bodies being arranged in the plane of symmetry of the device (1). The axes (14) of rotation of the three roller bodies (13, 20, 21) are aligned perpendicular to the rocking plane of the device (1). Since part of the circumferential surface of all three roller bodies (13, 20, 21) projects over the convex surface of the rocker (3), while the axes (13) of rotation are arranged on the concave side of the rocker (3), the device (1) is given the possibility not only of tilting over the cylindrical roller body resting on the floor, but also of moving on the floor. By rocking the device (1) backwards, the centre of gravity of the eccentrically mounted roller body (13), which is then not loaded, is displaced downwards whereas, when rocking forwards, a rotational movement is forced upon this roller body (13). By simply demounting the roller bodies (13, 20, 21), the device can also be used as a stationary rocking device. <IMAGE>

Patent DE-3238828-A1 (DE)
Title: Method of laying several sinking pieces one after the other in flowing stretches of water
IPC: E02B3/12
Filed: 1982-10-20
Abstract: The invention relates to a method of laying several sinking pieces one after the other in a laying direction running transversely to the flow direction of a flowing stretch of water, in which method the orientation of the sinking pieces in laying positions between sinking pontoons and the sinking are carried out by loading with rubble. Several sinking pieces are placed next to one another in their sinking order, their longitudinal sides being orientated parallel to one another. After the first sinking piece is released from the bond with the other sinking pieces, it is sunk. In the process, the edge of the following sinking piece facing the flow is held up so that it cannot undercut in the flow. The remaining sinking pieces are then laid or sunk in succession in such a way that a sinking piece is drawn and orientated laterally over the already sunk sinking piece, then the sinking piece is advanced in the laying direction up into the laying position and is then lowered. The sinking piece following in turn is subsequently drawn up and advanced again into the laying position and sunk.

Patent DE-3245474-A1 (DE)
Title: Process for regenerating an iron chloride/copper chloride etching solution
Inventor: NAUMOV JURIJ IVANOVIC
IPC: C23F1/46
Filed: 1982-12-08
Abstract: A process is proposed for regenerating an iron chloride/copper chloride etching solution in which the etching solution is separated at least into two flows. One of the flows is fed to the zone between the cathode and the anode, which is made of a porous material permeable to atomic chlorine, at a velocity which ensures a laminar movement of the etching solution over the surface of the electrodes. The second flow is fed into the zone behind the anode at a velocity which ensures a turbulent movement of the etching solution over the anode surface. In this process, the ions of the divalent copper are electrochemically reduced to metallic copper at the cathode, and at the anode the ions of the divalent iron are oxidised to those of trivalent iron and the chlorine ions to atomic chlorine. The latter diffuses through the pores of the anode into the zone behind it and oxidises the ions of the divalent iron.

Title: Device for cutting up boards, especially particle boards
Inventor: WARNECKE VOLKER
IPC: B27B5/06
Filed: 1983-01-07
Abstract: The device for cutting up boards, especially particle boards, with a longitudinal saw and a transverse saw, is used to cut up boards or stacks of boards which have been divided up in accordance with a cutting plan. A paternoster station 11 consisting of at least two levels 16, 17, 18 is arranged upstream of the transverse saw so that the longitudinal strips A, B, K which are to be sawn transversely can be sorted in accordance with the determined cross sections, i.e. the transverse division. Intermediate storage in the paternoster station makes preliminary sorting possible, so that packs of longitudinal strips with the same cross section can be cut up together by the transverse saw. Optimum use and loading of the transverse saw is possible in this manner. In addition, boards which have been presorted in accordance with their dimensions to a greater or lesser extent leave the device, making stacking easier. <IMAGE>

Title: Arrangement for detecting faulty limit monitors
Inventor: WASELOWSKY GERHARD
IPC: B67D7/32
Filed: 1983-03-12
Abstract: To prevent tanks being overfilled with easily flammable liquids (fuels), electrically operated filling safeguards are used. The filling safeguards operate in conjunction with limit monitors which are inserted into the tank and when a predetermined liquid level is reached, apply a signal to the filling safeguard connected to it so that a valve device connected to the filling safeguard interrupts the supply of liquid from there. Limit monitors can become faulty in the course of time due to external and internal influences and can thus no longer fulfil their function. To be able to detect such limit monitors as faulty during operation, an arrangement is proposed which can be easily installed in already existing filling safeguard arrangements. This arrangement comprises a four-terminal network (1), the two input terminals (2, 3) of which are used for connecting the limit monitor (4) and the two output terminals (5, 6) of which are used for connecting the switching amplifier so that this arrangement can be switched in a simple manner between limit monitor and filling safeguard. <IMAGE>

Title: Safety device for electrical apparatuses
Inventor: HERRMANN DIETER DIPL ING
IPC: H01H9/22
Filed: 1983-03-18
Abstract: The invention relates to safety devices for electrical apparatuses having a central safety block in which operating flaps must be protected against opening during operation. The aim is to achieve a common safety system in a simple manner. The idea of the invention is for the design to make use of the locking of operating flaps in the central safety block. This is achieved according to the invention in that a mechanical connection between the locking mechanism of the operating flap and the main protection switch of the central safety block is arranged in such a manner that in the "on" switch position, the operating flap cannot be opened and, when the operating flap is open, the main protection switch cannot be moved into the "on" position. The invention is particularly suitable for use in fully automatic washing machines. <IMAGE>

Patent DE-3317121-A1 (DE)
Title: Linear ball bearing
Inventor: TERAMACHI HIROSHI
IPC: F16C29/06
Filed: 1983-05-06
Abstract: The invention relates to a linear ball bearing for use in machine tools, transport robots and the like. The linear ball bearing comprises a bearing body with a pair of leg-like side walls which are provided on their opposite surfaces with longitudinal ribs. The bearing body furthermore has ball rolling grooves which are arranged in both lateral surfaces of the longitudinal ribs and form parts of ball channels for loaded balls. The bearing body furthermore forms ball channels for unloaded balls, corresponding to the ball channels for loaded balls and arranged essentially in the central part of the leg-like side walls. The linear ball bearing furthermore comprises a guide rail which is provided on its two lateral surfaces with recesses for receiving the longitudinal ribs of the bearing body. The recesses are provided on their two side walls with ball rolling grooves which form parts of the ball channels for loaded balls. Connected to both ends of the bearing body are caps which form the ball deflection grooves by which the ball channels for loaded balls are connected to the corresponding ball channels for unloaded balls, thereby making it possible for the rows of balls to circulate through the ball channels for loaded balls and then through the ball channels for unloaded balls. In one embodiment, the ball channels for unloaded balls are formed by bores within the leg-like side walls of the bearing body. In another embodiment, the ball channels for unloaded balls are formed by indentations formed on the outer sides of the leg-like side walls of the bearing body and extending in the longitudinal direction of the bearing body and by ball elements which are inserted into these indentations, the ball channels for the unloaded balls being formed between the inner surfaces of the indentations and the inner surfaces of the channel elements.
Patent DE-3319225-A1 (DE)
Title: Thermal switch
Inventor: SCHWARZ GERHARD
IPC: H01H37/54
Filed: 1983-05-27
Abstract: In a thermal switch for temperature monitoring, the contact region is constructed such that the contact tongue has a contact lug which points approximately parallel to the axis of the bimetallic snap disc and, when the contact is closed, is pressed against the end surface of the connecting tab, which is constructed as a mating contact, but which comes to rest outside the end surface when the contact is open.   A contact region on the connecting tab is thus produced when the contact is closed, and a separating region when the contact is released, which brings the advantage that any erosion deposits which may occur as a result of arcing effects when the contact is open cannot act in the contact region and cannot cause the contact to deteriorate. This effect can be further reinforced by suitable construction of the mating contact and of the contact lug, so that, in the final result, it is possible to dispense with the previously necessary use of noble metals in the contact region for reducing arcing effects, and it is thus possible to reduce the cost of the thermal switch (Figure 1). <IMAGE>
