Title: Agricultural harvesting machine
Inventor: DUECKINGHAUS HEINRICH
IPC: A01D41/14
Filed: 1993-08-05
Abstract: The present invention describes an agricultural harvesting machine with a reversible auxiliary drive for reversing the direction of rotation of the draw-in device for the crop by means of simple and robust components, without the need to use a multiplicity of switching and control elements. For this purpose, use is made of a known hydraulic motor flanged on pivoting arm, pivotable about an axis which is axis-parallel to a drive shaft, onto which a driving spur wheel is attached fixedly in terms of rotation. Keyed onto the drive journal of the hydraulic motor is a pinion which meshes with the driving spur wheel for the reversed drive of the draw-in device. The pivoting movement necessary for the purpose is generated by the piston/cylinder unit. The return movement takes place by means of a pretensioned compression spring.

Title: Method to operate IC engine with deactivateable combustion chambers - uses set chronological sequence to switch-off fuel supply, free by=pass, and switch-off fresh air intake
Inventor: KRUEGER HINRICH DIPL ING
IPC: F02D17/02
Filed: 1993-09-14
Abstract: The method employs the steps of switching off the fuel supply, freeing the bypass line (8), and reducing the fresh air feed. These take place at such relative time lapses, that a circulating airflow passes through the deactivated combustion chambers (1) and the bypass line. With cancellation of deactivation by switching the fuel supply back to its idling level, blocking of the bypass takes place at such a time distance before renewed switch-on of the fuel supply, that the intake tube pressure at this time has reached approx. its idling level. ADVANTAGE  - Uses simple method to guarantee good fresh air filling to deactivated combustion chamber, when fuel supply is switched on again.

Title: Switching device having a supporting appliance in order to reduce contact bounce, as well as a method for dimensioning the damping bodies which are used in this case
Inventor: PAUL BERNT DIPL PHYS DR
IPC: H01H50/30
Filed: 1993-09-16
Abstract: Air contactors for the low-voltage range, in particular, have a contact arrangement consisting of at least one stationary contact on a support and at least one moving contact, preferably in each case two contacts on a switching link. Furthermore, there is normally an electromagnetic drive with a movable armature as well as (frequently) a supporting device which brakes the speed of the moving contact, as a result of which undesirable contact bouncing during switching is intended to be reduced. According to the invention, the supporting device is partially decoupled from the attracted armature (12) of the electromagnetic drive (8 to 12) via spring elements (6) and consists of at least one damping body (25, 28) which is connected parallel to the contact movement and has predetermined internal friction, the damping body (25, 28) being mounted on the support (21) for the stationary contact (2), laterally with respect to the movement direction and alongside the contact arrangement (2, 4). In the case of the associated dimensioning method for the damping body, a computer model for the multi-body system which is represented by the switching device is used to calculate the movement sequence of the multi-body system for individual body elements (i) in each case of point masses (mi) each having only one degree of freedom. <IMAGE>
Patent DE-4335515-A1 (DE)
Title: Opposed-piston two-stroke internal combustion engine with spark ignition, direct fuel injection into the cylinder and stratified charge
Inventor: PULCH OTTO C
IPC: F02B1/04
Filed: 1993-10-19
Abstract: Two-stroke engines are simple to construct and have a low weight. However, the charge cycle is difficult to monitor and measures within the engine against the production of pollutants are difficult to implement. The use of the opposed-piston principle with control times which can be changed during operation can vastly reduce the production of pollutants. In such a motor, it is possible to charge the cylinder with three strata (layers). An ignitable mixture with some of the air which has flowed in is formed above one piston by fuel injection, and a regulatable-quantity exhaust-gas residual stratum is located above the second piston. Air which serves to increase the air/fuel ratio lambda during combustion is located between said two layers. The combustion space forming between the two pistons has a geometrically minimised wall surface area for the heat dissipation. A suitable selection of materials reduces the heat dissipation in this high-temperature range still further, with the result that the thermal efficiency increases. The engine is suitable as a replacement for Otto engines, it being superior to the latter in terms of cost-effectiveness and pollutant emission.

Title: Central real-time monitoring unit for biological signals and vital functions of a multiplicity of mutually unshielded persons who are located in the receiving region of the monitoring unit, by means of telemetric signal transmission
Inventor: MAYER WILFRIED
IPC: A61B5/00

Abstract: The invention relates to a central real-time monitoring unit for biological signals and vital values of a multiplicity of mutually unshielded persons who are located inside the radius of action of the monitoring unit and are not stationary, by means of telemetric signal transmission by using high-precision narrow-band transmitters with a defined frequency raster (frequency spacing). The system permits one or more persons to be monitored simultaneously and continuously and allows the creation of an uninterrupted protocol, which is independent of the location and the type of movement, over the entire duration of presence in the radius of action of the system.

Title: Towed paraglider
Inventor: ROSENKE ULRICH
IPC: B64D17/02
Filed: 1993-10-22
Abstract: As Figure 1 shows, the invention relates to a towed paraglider having a towed supporting body which is formed from flexible materials, can be inflated by the incident air, is like a wing and has a wing top and a wing bottom, which [lacuna] in one or more planes, which run at right angles to the span direction, in each case by means of the arrangement of a plurality of flexible structural elements, such as ribs, material strips, ribbons. Cables on a large number of points in the profile depth direction are connected such that, in the inflated state, the intended profile thickness prevails locally there, and which develops intrinsic lift by means of a towing device through the motion in the air, and thus represents a self-supporting towed supporting body. The invention which is specified in the claims is based on the problem of producing a towed paraglider which makes it possible to allow the towing forces to act on the paraglider such that it assumes a favourable flight attitude and maintains this attitude while climbing, towing through the air and descending. This problem is solved by a towed paraglider which is characterised in that a plurality of towing and holding lugs (1) of different sizes are fitted to the underneath of the wing in such a manner that the tension forces, which are directed forwards in a straight line, are distributed uniformly over the towed paraglider which predominantly assumes an aerodynamic flight attitude, and this in virtually all flight attitudes...
