Title: Force multiplier
Inventor: JAKOB LUDWIG
IPC: B25B5/10
Filed: 1993-09-08
Abstract: A description is given of a force multiplier in which a wedge-shaped slide (1) pushes pressure pieces (2) into radially narrowing gaps (3). The proposal according to the invention is that all the faces (1/2), (2/5) and (2/6) which transmit the force should be flat, that the axial thrust should be produced by means of two threads (7/4) and (7/1) acting simultaneously in series and that the distance between the lower edge (8) of the actuating hexagon (9) and the upper edge (10) of the housing (4) should be used as a means of controlling the clamping stroke. <IMAGE>

Patent DE-4432950-A1 (DE)
Title: Automatic amplification control of digital data signal
Inventor: LUETZELER JOERN DR
IPC: H04N5/931
Filed: 1994-09-16
Abstract: The control is for a digital data signal with asymmetrical signal amplitudes. A controllable amplifier is located in the signal path and its amplifying effect of its output signal is controlled after comparison with a reference signal.  The output signal is measured to determine positive and negative peak values, and then the voltages corresp. to the measured signal peak values, are mutually subtracted. The resulting voltage value is compared to a reference value, and serves for final control of the amplifier.

Inventor: RUNKEL ADOLF
IPC: E04G21/12
Filed: 1984-05-23
Abstract: Method for connecting two bars (61, 62) which are crossing each other, particularly reinforcement bars in an armoured concrete construction, and device for implementing such method. The method utilizes a tongs-like tool (4) which is first closed around the bars to be connected; a wire (59) is then fed, shorn and clamped, whereafter the tongs are opened and the two bars are pushed away from the tongs area by means of a pusher (36). Finally, the tongs are reclosed to perform a rotation motion in order to twist the wire ends about the reinforcement bars to be connected. The device for implementing said method is comprised, as constitutive elements, of wire supply channels (45, 46) which are completely closed and arranged in both tongs arms (5, 6) of the tongs-like tool, and said tongs arms (5, 6) enable to control the clamping device (18) as well as the shearing device (14, 48).

Patent WO-8705076-A1 (WO)
Title: Piston engine
Inventor: GREINER PETER
IPC: F16J1/00
Filed: 1987-02-24
Abstract: The piston engine consists of a cylinder block with at least one cylinder in which the piston, equipped with at least one piston ring and connected with the crankshaft, is arranged to move up and down. In order to take account, in the engine, of present-day trends in respect of fuel saving and environmental pollution without thereby having to abandon the existing design principle, the engine is so designed that the piston (1) is constructed of modified carbon, with a flexural strength in the region of approximately 75 N/mm2 and its top (2) at least on the admission surface (2') is treated to be resistant to burn-off. At least the operative surface (3) of the cylinder (4) is made of the same material but treated on its operative surface or of a similar material such as siliconized carbon, silicon carbide, silicon nitrate or similar, with roughly the same thermal expansion behaviour as that of the piston (1). The same applies for the piston ring (5) which, in addition, as regards its elasticity, is provided with the necessary elasticity either by virtue of its construction or by the choice of a sufficiently elastic material. Finally, the drillings (12) on the piston (1) for the piston gudgeon pins are dimensioned in relation to the outside diameter of the piston gudgeon pin (13) with a clearance which ensures a minimum clearance at the operating temperature.

Abstract: Dans un dispositif optique de projection d'affichages à cristaux liquides, en particulier des rétroprojecteurs ayant une plaque de cristaux liquides (12) sur le plan de projection et une lentille de Fresnel (13), les rayons de lumière (23) d'une lampe de projection se propagent en sens parallèle ou essentiellement parallèle à l'intérieur de la plaque de cristaux liquides (12). Dans un rétroprojecteur fondé sur le principe de réflexion, une lentille de Fresnel (13) est agencée au-dessus du côté de la plaque de cristaux liquides (12) faisant face à la lampe de projection (18) et un miroir plan (14) est agencé au-dessous du côté de la plaque de cristaux liquides (12) à l'opposé de la lampe de projection (18). Grâce à cet agencement, le rayon incident de lumière (23) en provenance de la lampe de projection (18) peut ressortir par la même cellule ouverte (20) de la plaque de cristaux liquides (12), par laquelle il est entré, après avoir été réfléchi par le miroir plan. Ce simple agencement permet d'éviter la formation d'ombres et de contours doubles lors de la projection d'affichages à cristaux liquides.

Abstract: Selon un procédé de commande pilote et de régulation adaptatives des mélanges d'air et de carburant à fournir aux deux systèmes de dosage du carburant d'un moteur à combustion interne ayant deux canaux séparés d'échappement pourvus chacun d'une sonde lambda et d'un catalyseur, une valeur commune de commande pilote et une valeur prescrite commune de lambda sont déterminées pour les deux systèmes de dosage du carburant. Par contre, des valeurs séparées de régulation, ainsi que les valeurs d'adaptation de la commande pilote, sont déterminées pour chaque système de dosage du carburant et qui en dépendent superposées séparément l'une après l'autre à la valeur commune de commande pilote. Ce procédé permet de régler avec un seul système les deux bancs de cylindres qui doivent être réglés dans le cas d'une stéréorégulation lambda.
