Patent DE-19602053-A1 (DE)
Inventor: KLASCHKA RUEDIGER
IPC: G08G5/04
Filed: 1996-01-20
Abstract: This invention proposes equipping aircraft (10, 12, 14) and other objects with a monitoring unit (16, 18, 20) in order to monitor the path of such objects independently of a control center. The monitoring unit continuously emits the positional data which are determined by a GPS unit, and course data of the object. The monitoring units (16, 18, 20) receive simultaneously the corresponding data from other objects, extrapolate the path being travelled and the paths of the other objects and check whether these paths are closer together than a pre-set security margin.

Patent DE-19620379-A1 (DE)
Title: Equipment well=suited to make several thermoplastic spun=bonded webs
Inventor: GEUS HANS-GEORG DIPL ING
IPC: D04H3/02
Filed: 1996-05-21
Abstract: Equipment for continuous production of a spun-bonded fleece web from thermoplastic filaments drawn aerodynamically comprises:  Spaniard (2); a system (3) with blower supplying process air; a filament drafting system (4) with lower drafting channel (5); a filament depositing system (6) with diffuser (7); an ambient air entry gap (8) between channel and diffuser; a filter screen belt machine (9) with continually and evenly circulating belt (10); a first set of press rollers (11) before the diffuser in the belt travel direction; a second set (12) after the diffuser and; a suction fan (14) with duct (15) under the belt in the region between the lower press rollers. Spun-bonded fleece is laid on the belt and process air enters the depositing system from the drafting system, functional separation of systems being achieved by:  1) independent control of blower and suction fan; 2) choosing the air gap size in the lower drafting channel so it acts as a barrier (S) and decouples the systems aerodynamically and 3) making the ambient air entry gap adjustable relative to the channel air gap size.  Equipment flexibility in relation to the operating conditions pertaining to the product is obtained by so adjusting the ambient air entry gap and the fan suction power that the static pressure of the suction air flowing off in the diffuser over the belt is nearly that of the ambient air and the suction air mixed via the ambient air entry gap in the diffuser experiences a deceleration which avoids the filaments forming cords.

Patent DE-19624922-A1 (DE)
Title: Optical measuring process for measuring alternating quantity
Inventor: MENKE PETER
IPC: G01R1/07
Filed: 1996-06-21
Abstract: The method requires measurement of alternating parameters e.g. alternating current or voltages. Polarised measuring light passes at least once through a sensor device which is under the influence of the parameter. The sensor device changes the polarisation of the light depending on the parameter. After passing through the sensor, at least one electric signal is taken from the measurement light as a measurement of the polarisation state of the light.  The electric signal is then converted into a transformed signal which is an odd function of the parameter. A constant component of the transformed signal is formed by temporal averaging. This component contains no frequency component of the alternating parameter. A continuous temp. dependent measurement signal for the alternating parameter is formed from the constant signal component and the transformed signal or a signal taken from the transformed signal.

Title: Inverter output voltage control method - requires digital control of voltage in each phase using control variable formed from difference between actual and setpoint phase voltage
Inventor: BLACHA NORBERT DR
IPC: H02M7/5387
Filed: 1996-07-30
Abstract: A procedure for controlling the voltage at the output of an inverter with a controller in each phase has the following features. The effective voltage value is controlled. The control process is digital. One command variable is passed to each controller. Each is the sum of a given fixed value and a cyclically evaluated matching value for the respective phase. This matching value is the difference between the actual effective output voltage for the respective phase and its setpoint value. Each difference is passed to an integrator, whose output is multiplied by a proportionality factor. The voltage in each phase is constantly sampled at discrete times.
Patent DE-19634434-A1 (DE)
Title: Heavy-current connector plug e.g. for electric vehicle
Inventor: FUKUSHIMA HIROTAKA
IPC: H01R13/15
Filed: 1996-08-26
Abstract: The high-power electrical connector has hollow cylindrical element 14 set into a housing of insulating material. Located in the cylinder is a contact element 12 that can be displaced axially against a coil spring 13.  The contact pin is in contact with the inner surface of the cylinder via a contact band 15 that is formed of thin spring type metal and has a mesh pattern. This allows free axial movement of the pin while preventing radial movement. The contact pin is displaced when inserted into a mating connector.
Patent DE-19635152-A1 (DE)
IPC: B21D53/28
Filed: 1996-08-30
Abstract: A process is disclosed for manufacturing a gear part with outer teeth from a metallic workpiece shaped as a circular blank or predrawing. The gear part has a hub surface with outward projecting teeth. The workpiece is flattened in its circumferential area and the teeth are formed without cutting in a toothed roller (5) mounted in a freely rotary manner. While the teeth are formed by flattening the workpiece, the toothed roller (5) is fixed in the radial direction so as to not move towards the feeding axis of the spindle. The edge of a circular blank may be curled or thickened or the cylindrical edge of a pot-shaped predrawing may be collapsed.
Patent DE-19635457-A1 (DE)

Patent DE-19644431-A1 (DE)
Title: Variable-output compressor for air conditioning system of motor vehicle
Inventor: FUKANUMA TETSUHIKO
IPC: F04B27/10
Filed: 1996-10-25
Abstract: The compressor incorporates a swashplate (30) mounted at a variable angle on a driving shaft in a crankcase and actuating pistons (24) working in the axial direction in a cylinder block. The pistons compress a cooling gas delivered into the cylinders from an external circuit via a suction chamber. The swashplate angle varies dependent on the pressure difference between the crankcase chamber (25) and the cylinders, thus varying the piston stroke. It also shuts a plug (47) so as to cut the suction chamber off from the external circuit when at the minimum angle. A valve plate (14) between the cylinders and a gas chamber forming the suction or delivery chamber has an opening connecting the two and closed by a valve (59, 61). A passage is formed between the valve plate and valve with the latter shut, and connects the cylinders (23) with the gas chambers (41,43). The passage can be formed between the opposite surface of the valve and plate and round the opening. The opening can form an outlet, controlled by the valve, connecting the cylinders and outlet chamber.

Title: Grommet for wall-entrance of cable
Inventor: KESSEL BERNHARD
IPC: F16L5/10
Filed: 1996-11-15
Abstract: A sleeve for sealing a hole in a wall which a pipe or cable goes through is made of elastic material and at each end(3,9) has reinforcement overlapping the hole, pointing outwards. In the untensioned state of the sleeve, at least one of these reinforcing lips (7) projects only slightly beyond the edge of the hole and inwards.

Title: Weighing scales, e.g. for use on kitchen work surface or floor
Inventor: SCHOLPP WERNER
IPC: G01G19/52
Filed: 1997-01-14
Abstract: The weighing scales (6) has a rocking plate (7) installed flush with the surface of a floor (2) or pathway and  consists of a trough (1) inserted in a pit. The measuring device is visible through the balance plate. A smaller under-trough (11) forms a deeper section (5) within the main trough. The rocking plate has a bell-shaped frame (8) on the under side. This forms an air-tight upper inverted trough. An auxiliary trough (9) clips within this. These move freely in a vertical direction above the under-trough during weighing, so that between the edge of the plate and the edge (3) of the trough there is no way in which water can enter. This protects the weighing mechanism without obstructing it, ensuring continuing accuracy in use.
