Title: Internal combustion engine
Inventor: LOHFF BERNHARD
IPC: F01C1/344
Filed: 1988-07-04
Abstract: The aim of the present invention is to save fuel in order to safeguard the environment. The drawings Fig. 1 and 2 clearly show this. According to Fig. 1 the rotary engine is to be manufactured to a simple, entirely hollow design with piston rotor (3) and crankshaft (2), which represents a considerable weight saving which promotes acceleration. The housing (1) comprises two symmetrical halves, which according to Fig. 2 each have a restriction (26) at the exhaust and inlet end for limiting the piston rings (24), in each half contain an inlet (16) and an exhaust (17) and each uniformly divided by three separating plates (5) into intake chamber (18), compression chamber (19) and expansion chamber (20), show the function of the engine. The separating plates (5), 1cm thick, move on needle rollers (9) in pockets (6) of the piston rotor (3), and tapering at the head end are provided with ceramic surfaces for durable sliding. The piston rotor (3), wall from 0.4cm thick, is fixed to the hollow crankshaft (2) (from 4cm inside diameter), provided with pockets (6) for accommodating the separating plates (5) designed with a leading recess (22) in the direction of rotation and on the outermost edge of the rotor the movable bearing for each of 2 steel piston rings (24) for complete bilateral sealing in the combustion chambers. Due to the engine design explained above, the centre of gravity in operation lies on the outermost edge so that the centrifugal force ... Original abstract incomplete. <IMAGE>

Title: Method and device for storing and transmitting medical image data
Inventor: TAWARA KIYOSHI
IPC: G16H10/60
Filed: 1988-07-08
Abstract: Medical image data is recorded by an image production unit (50a, 50b, 50c) of a physical engineering system (21), and stored in a module database (24) which belongs to this system. If an image data request command to the module database (24) is entered from a work-station (62a, 62b, 62c) of a console (41) via a network (22, 63) and a distributing amplifier (70), the image data which is stored in the module database (24) is transmitted to the work station (62a, 62b, 62c), and shown on a display device of the work-station. By viewing the image data for the purpose of diagnosis, additional data is gained. The image data and additional data are transmitted from the work-station (62a, 62b, 62c), via the network (63), to the database (24), and are stored in an intermediate magnetic disk memory (18a, 18b, 18c) and an optical storage disk (58a, 58b, 58c) of the database (24). <IMAGE>

Title: Method and apparatus for the path-controlled dressing of a grinding-wheel profile
Inventor: MUSHARDT HEINRICH DR ING DR
IPC: B24B53/06
Filed: 1988-07-27
Abstract: A method and apparatus for the path-controlled dressing of a grinding-wheel profile are described. The grinding-wheel profile has profile sections (P1) running parallel to the grinding-wheel axis (38), a profile section (P2) running in a curve and a profile section (P3) running, as a profile flank, at an angle  alpha  to the grinding-wheel axis. According to the invention, the feed of the dressing tool (22) is controlled such that the path speed v of the point of action (WP) between the grinding surface of the grinding wheel (13) and the dressing tool (22) is varied in a controlled manner as a function of the angle  alpha . As a result, the depth of the feed grooves (41) is influenced during the dressing in a preset manner, so that the grinding wheel receives a preset sharpness profile along its grinding profile. <IMAGE>

Patent DE-3835131-A1 (DE)
Title: Method of fixing roofing and ceiling webs of ECB
Inventor: HEYEN JOHANNES
IPC: C09J7/10
Filed: 1988-10-15
Abstract: For the method of fixing roofing and ceiling webs of ECB, especially when combined with mechanical fixing, a double-sided adhesive strip consisting of styrene-butadiene-styrene bitumen is additionally applied in the region of mechanical fixing. This double-sided adhesive strip acts as a protective coat for the fixing panels and as an additional adhesive bond for the overlap. In this way stresses arising in the web are taken away from the weld seam, thus relieving the load on it. The sealing effect is consequently added to and doubled.
Patent DE-3840660-A1 (DE)
Title: Steering linkage for motor vehicles
Inventor: RAMPF WILLY
IPC: B62D7/16
Filed: 1988-12-02
Abstract: A steering linkage system for motor vehicles is described, in which a central track rod (1, 1') is actuated by means of a steering lever (3) and lead to a steering guide lever (4). For this purpose, the steering lever (3) is connected to the central track rod (1, 1') via a ball-and-socket joint (2). The steering guide lever (4) has an articulated connection (5) to the central track rod (1, 1'). It consists of two ball-and-socket joints (7, 8, 8') which are connected via a bearing pin (10) which acts as pivot axis. A third ball-and-socket joint (6, 6') which, like the ball-and-socket joint (7), is arranged on the steering guide lever (4) is connected to the ball-and-socket joint (8, 8') via a coupling rod (9, 9'). The central track rod (1, 1') is permanently arranged on the bearing pin (10). The articulated connection (5) thus produces a stable arrangement in the case of torsional stressing of the central track rod (1, 1'). Inaccuracies, for example of the angular position of the steering guide lever (4), arising from production and tolerance reasons are thus compensated. <IMAGE>

Patent DE-3908441-A1 (DE)
Title: The EMKA method
Inventor: POISEL OTTO KARL DIPL ING
IPC: B64G1/40
Filed: 1989-03-15
Abstract: The point of origin of this method is the physical law of nature that it is not possible to destroy energy but only to convert it. Cosmic activities include space flight and communication. Both cases relate to a certain amount of energy being stored in mass, whether in the form of a body or a large number of particles, with the aid of acceleration and a high velocity. Part of this energy can be recovered by both parameters being reduced to zero again with the aid of a decelerator which at the same time is also a generator. It is thus possible to talk of "milking" this mass. The efficiency of these activities depends on how much we recover from the ratio of the final energy (E2) to the initial energy (E1), and in doing so it is possible to speak of a type of cosmic energy. <IMAGE>

Title: Connectors for multi-path media in plate heat exchanger - are all incorporated in fixed end plate
Inventor: FUNKE KARL-HEINZ
IPC: F28F3/08
Filed: 1989-04-19
Abstract: Heat is exchanged between two media flowing in meander fashion through the alternate gaps in a set of plates (1,30) welded or brazed together, or held in contact by terminal pressure plates (26,28) supporting the set on a base support (24). The media path through the structure is such that both inlet and outlet terminals (32,34; 36,38) for both flowing media are formed in only one of the terminal plates, and lead directly into the terminal gap (11,12) between the last two exchanger plates at that end. Inlet and outlet terminals are pref. near one edge of the terminal plate concerned.  With a plate set having a fixed and a mobile pressure plate, the media terminals are formed in the fixed plate. ADVANTAGE - Terminal arrangement is simplified, and no terminals require removal before the mobile pressure plate is released.

Title: Simultaneous measurement of forces and torques - with decoupling of the different force and torque components and temp. compensation using outer frame spring coupled to rigid axes
Inventor: PUTTKAMER EWALD VON PROF DR
IPC: G01L5/16
Filed: 1989-11-08
Abstract: Simultaneous measurement of forces and torques involves detecting the forces and torques acting on an outer frame. The measurements are performed contactlessly from three rigid axes wrt. which the outer frame can move. The measurements of force and the measurements of torque in the axial directions are decoupled from each other, whereby the outer frame is connected to the rigid axes via springs. USE/ADVANTAGE - Measuring forces and torques simultaneously enables the different components of a measurement force and torque to be decoupled and temp. influences to be fully compensated using simple arrangement.
