Title: Digital signal converter with nonlinear conversion characteristic
Inventor: SCHENK HEINRICH DR ING
IPC: H04B3/23
Filed: 1987-02-18
Abstract: Using the digital signal converter according to the present invention, it is intended to be possible to convert input digital signals into output digital signals, which are nonlinearly dependent on the input digital signals, with little circuit expenditure. In the digital signal converter, only signal element combinations formed by fixed signal elements of the input digital signals are used for selection of a segment of the conversion characteristic which is in each case permanently allocated to these combinations. For the respective segment, an output digital signal y of the form y = aix + bi is formed, where x is the input digital signal to be converted in each case and ai, bi are a coefficient pair allocated to the segment selected in each case. The digital signal converter can be used as nonlinear echo canceller in data transmission devices for transmitting digital signals by the duplex channel method via two-wire lines.

Title: Cooling system for the lubricant of an air-cooled internal combustion engine
Inventor: POEHLER HANSJOERG DIPL ING
IPC: F01M5/00
Filed: 1987-04-25
Abstract: The invention relates to a cooling system for the lubricant of an air-cooled internal combustion engine with forced-feed lubrication by a lubrication pump and valve gear arranged in the cylinder head, in which system the lubricant in the cylinder head is collected in a collecting chamber and flows back by way of a return passage into the oil sump. Whilst the aim of the invention is an adequate cooling of the lubricant matched to the operating temperature, the object is to create a simple cooling system at low cost and taking up little space by means of a special design and arrangement of the lubricant return flow. This object is achieved in that in the collecting chamber an overflow is also arranged, which opens directly into the oil sump, whilst the return passage has a shut-off valve and is connected to a recess in the cylinder, from whence a plurality of passages, which in a known manner lie in the area flushed by the coolant, lead through the cylinder into the oil sump. <IMAGE>
Patent DE-3719885-A1 (DE)
Title: Physical training apparatus for improving power for jumping and running
Inventor: HUTT ECKHARD
IPC: A63B23/04
Filed: 1987-06-13
Abstract: By cumulation of the loading effect of the variable load of a pendulum in the horizontal direction and of the variable load of the weight support (hip yoke) movably attached to the pendulum in the vertical direction, a load direction pattern is achieved for the person training which corresponds to that in jumping or sprinting (drawing 6). As a result of the adjustable length of the pendulum and its distance from the floor surface, it is possible to limit the movement of the hip yoke towards the axis of rotation of the pendulum at the height of the hip curve. As a result, training is possible in the same muscular modes of action as with jumping, in sequence eccentric - isometric - concentric, but without the abrupt stresses of jumping for the passive motor apparatus of the person training. The direction of load is adjusted by the tension cable part of the apparatus to the requirements of the running load. As a result of the belt construction on the hip yoke (drawing 3) the load is distributed over shoulders and hips and thus permits greater stresses with simultaneous reduction of load on the spinal column in comparison with conventional training media such as dumb-bell training, etc..

Title: Hydraulic brake-actuating system
Inventor: LOETZSCH ULRICH
IPC: F16D65/18
Filed: 1987-09-25
Abstract: A description is given of a hydraulic brake-actuating system for a friction brake, which is equally suitable for service braking operations and parking. The actuating system comprises a brake cylinder (20) with two opposed brake pistons (21, 22), the mutually facing end faces of which form wedge faces (32, 33) inclined relative to the axis of the brake cylinder (20). Provided between the brake pistons (21, 22) is a locking wedge (31) which can be placed against the wedge faces (32, 33). The locking wedge is actuated by a locking-mechanism piston (34) arranged in a locking-mechanism cylinder (35) and projecting radially into the cylinder chamber (41). To lock the brake pistons (21, 22), the locking-mechanism piston (34) is subjected to the brake pressure in the brake-actuating position and the locking wedge (31) is thereby pushed between the wedge faces (32, 33). During the subsequent pressure reduction, the locking wedge (31) holds the brake pistons (32, 33) in their brake-actuating position owing to the frictional engagement existing. <IMAGE>
Patent DE-3737171-A1 (DE)
Inventor: WESTERHEIDE KLAUS DIPL ING
IPC: F21Y103/00
Filed: 1987-11-03
Abstract: In known tubular mounting systems, in which two core parts of semicircular cross-section are forced apart by a screw and pressed against the interior of half-shells at only two facing positions, the pressure faces are very small and the connection between the tubes is therefore weak. With the new mounting system, a stronger connection can be achieved simply and reliably. For this purpose, at least three core parts (7) and at least one wedge (9) which can be braced by the screw (5) against the core parts (7) and can spread the latter in several radial directions are provided. As a result of the bracing produced over the entire periphery, the wall thickness of the tubes can be reduced and the volume of the core parts with the wedges can also be less than in the known execution. The entire mounting system is therefore lighter but nevertheless more stable.

Abstract: The invention relates to a method for ramming foundry sand in a moulding box which is placed on a pattern plate provided with a pattern and holes for the passage of air. After the foundry sand has been introduced loosely into the moulding box, it is acted upon briefly by compressed air and then compressed by means of a press. In known methods, it was either impossible or possible only at great expense to compact the foundry sand sufficiently to achieve a good casting surface, particularly at critical points of the pattern to be moulded. According to the invention, air is passed through the sand during the pressing operation. A method according to the invention can be employed in the production of all types of sand moulds.

Title: Printed circuit board for an electrical circuit, especially in an office machine
Inventor: KERZEL GUENTER
IPC: H05K1/14
Filed: 1987-12-19
Abstract: For office machines which are to be constructed in a compact manner, it is necessary for the assemblies and modules (building blocks) to be constructed in a correspondingly compact manner as well. Until now, suitable matching of printed circuit boards, which are constructed with a large area, to the available three-dimensional volumes has been a major problem. The invention is based on the object of constructing printed circuit boards which are constructed with a large area in such a manner that they can be produced using the means and manufacturing methods of modern large-scale manufacture, from the viewpoint of cost-effective production, and are compact. This object is achieved in that the printed circuit board (1) consists of printed circuit board parts (2, 3, 4) which can be separated from one another by means of weak points (7) and in that the printed circuit board parts (2, 3, 4) are firmly connected to one another by means of flexible conductive links (20, 21) which replace the conductor tracks (6) in the region of the weak points (7). Only after the complete printed circuit board (1) has been manufactured is it (1) suitably matched to the available three-dimensional volume, by bending at the weak points (7) provided. The links (20, 21), which are also bent during the bending process, ensure that the individual printed circuit board parts (2, 3, 4) reliably maintain their positions with respect to one another. <IMAGE>
