Patent DE-3536316-A1 (DE)
Title: Laminated oil cooler
Inventor: ENGLER GUSTAV
IPC: F28F9/22
Filed: 1985-10-11
Abstract: In a laminated oil cooler, a lamina packet consisting of individual lamina bodies is inserted into a housing. The housing is provided with an inflow and an outflow for the cooling medium whilst an inflow and an outflow for the oil to be cooled is provided at the lamina packet. In the lamina packet, the individual laminas are connected in parallel with respect to the through flow of the oil to be cooled, that is to say the oil to be cooled is distributed uniformly among the laminas. In contrast, the laminas are connected in series with respect to the through flow of the cooling medium, which results in the entire cooling medium flowing past each lamina. This series connection is achieved in that intermediate walls are provided between the individual laminas and have at edges facing one another openings through which the cooling medium can pass. In the case of a cylindrical lamina oil cooler, these openings are cut-off circular segments and the segments of adjacent intermediate walls lie diametrically opposite one another.

Title: Apparatus for guiding an unblocking spring
Inventor: POOS JOSEPHUS G D
IPC: E03C1/302
Filed: 1985-10-30
Abstract: A description is given of a novel apparatus (1) for guiding an unblocking spring (2) which is used for loosening and reducing deposits, such as dirt, in a line (4, 7) into which the unblocking spring (2) is pushed, with twisting. This apparatus (1) essentially has a foot (10) and a guide plate (9) which is arranged at a distance from said foot and is provided with means (15) in order to block the unblocking spring (2) with respect to the apparatus (1) if said spring detaches itself from the drive apparatus (3). The guide plate (9) is located at such a distance from the foot (10) of the apparatus (1) that, in the space between the guide plate (9) and the foot (10), unblocking fittings (6) can be fastened at the end of the unblocking spring (2). During the extension of the unblocking spring, this apparatus prevents the unblocking spring, which is already in operation and has been introduced into the line, from disappearing into the line, and it is possible, before introducing the spring into the line, to attach the unblocking fittings thereon. <IMAGE>

Patent DE-3642080-A1 (DE)
Title: Lathe
Inventor: ERMANNO MANCINI
IPC: B23B3/06
Filed: 1986-12-10
Abstract: A description is given of a lathe (1), in particular for machining rolls, composed of a headstock (13) with a spindle (15) which engages around the roll which is to be machined and causes the latter to rotate, and of two opposite tailstock centres (6, 7) which define an axis along which the roll (C), which is to be machined, is held. In this lathe (1), the spindle (15) is guided along the axis; one (6) of the two tailstock centres (6, 7) is mounted on a protrusion (17) in the direction of the other centre (7), the external diameter of the protrusion (17) being smaller than the internal diameter of the spindle (15) and its axial extent being greater than the axial extent of the headstock (13). The headstock (13) can thus be displaced into an end position in which the tailstock centre (6) projects out of the spindle (15) towards the other centre (7). The positioning of the roll, which is to be machined is simple by means of this lathe; moreover, the lathe takes up less space than analog lathes of the conventional type and it permits the machining both of the table (working surface of the roll) and of the necks (ends). <IMAGE>

Title: Multicylinder internal combustion engines with means for increasing the swirl
Inventor: OETTING HERMANN DR ING
IPC: F02D9/10
Filed: 1987-02-14
Abstract: For the purpose of optimising the flow conditions in the fresh gas lines (1) of an internal combustion engine, throttle valves (6), containing two vanes (6', 6'') capable of swivelling relative to one another and at the same time forming line control elements, with swivel axes (7) running parallel to the cylinder axes (9), are provided in all fresh gas lines (1) of the said engine. When idling and in the lower partial load range, only a first vane (6') of the two vanes (6', 6'') is opened as the load increases, so that a relatively high velocity flow generating a swirl in the combustion chamber is already produced, and only at the end of the opening movement of the first vanes (6') are the second vanes (6'') also moved into their open position, so that a relatively large flow cross-section with little flow resistance is now available in each fresh gas line (1). <IMAGE>

Title: Circuit arrangement for producing (generating) balanced (symmetrical) output voltages
Inventor: SCHUHBAUER ERNST DIPL ING
IPC: H02M7/217
Filed: 1987-02-24
Abstract: The circuit arrangement is intended to produce balanced output voltages at a particularly low cost, which balanced output voltages are as independent of the load as possible. The circuit arrangement contains a transformer (T) and a downstream rectifier (G) which emits the output voltages (+ U1, -U1). In order to balance the output voltages (+U1, -U1), a first voltage divider (S1) which is formed from reactive components (C5, C6) is connected in parallel with the rectifier (G), a reference potential (0 V) being emitted at the centre tap of the voltage divider (S1). Furthermore, a second voltage divider (S2) is connected in parallel with the first voltage divider (S1). This second voltage divider (S2) is constructed as an active voltage divider and balances the output voltages (+U1, -U1) in the event of an unbalanced load. Capacitors are preferably provided as the reactive components (C5, C6) and emitter followers, arranged in a balanced manner, are preferably provided as the active voltage divider. The invention is provided for output circuits of telex machines which emit bipolar signals (double-current signals). <IMAGE>

Patent DE-3709614-A1 (DE)
Title: Method and device for determining position
Inventor: PFEIFFER WALTER
IPC: G01D5/30
Filed: 1987-03-24
Abstract: The invention relates to a method for determining the position of a point of light produced by a light source on a one-dimensional position-sensitive detector, and is suitable, in particular for an optical potentiometer. In this case, the position of the point of light is determined by the quotient of the difference and the sum of two currents, which are dissipated at two electrodes situated opposite on the photosensitive surface of the detector. By controlling the light intensity of the light source, the sum of the currents is held constant, with the result that the position of the point of light is already yielded by the difference between the currents. <IMAGE>

Title: Process for producing a concrete block for floor or wall surfaces
Inventor: JOHNEN JOSEF
IPC: B28B23/00
Filed: 1987-12-11
Abstract: For producing a concrete block for floor or wall surfaces, a fresh mass of concrete with aggregates is formed, elevations and depressions being produced on a fair face of the block. Once the concrete block formed in this way has set, the elevations are surface-ground, the depressions remaining unchanged. The grinding operation is continued until the elevations have a smooth surface and the granular constituents of the aggregates form a significant proportion of the surface area, likewise in the smooth-ground state.

Patent DE-3809111-A1 (DE)
Title: Traversing device
IPC: B65H54/28
Filed: 1988-03-18
Abstract: For shifting threads to and fro, traversing devices with a straight-guided thread guide (1) are used. The thread guide is moved to and fro by means of a linear drive. At the same time, conventionally, the thread guide has to be uncoupled from the linear drive in the stroke-reversal regions, its kinetic energy cancelled and energy expended for the return movement. In order to avoid cancelling the energy and uncoupling, the thread guide is connected to the linear drive by means of a coupling member which is positively guided in the reversal regions between two deflecting guides (8, 9) and which is driven at the traversing speed. The coupling member (10) can be of linear design and be shorter than double the smallest traversing stroke. The coupling member possesses a sliding block (14) which engages into the slotted track (13). The coupling member can have a roller (23) which is driven by a rotating driving surface in the reversal regions. <IMAGE>
