Title: Electric machine with continuously variable mechanical adjustment - provided by relative movement of rotor and stator in conical configuration causing variation of air gap
Inventor: MESSERSCHMIDT WILHELM
IPC: H02K7/12
Filed: 1989-12-07

Title: Hydraulic press system - monitors upper dead-point drift to compensate for errors via digital display of average and instantaneous position of upper dead-point
Inventor: JARTYN HERMANN DIPL ING
IPC: B30B15/16
Filed: 1990-01-23
Abstract: The method and system records the position of the first dead point (OT2) at the start of a continuously alternating movement between two dead points. For N consecutive strokes or cycles, the sum of these positions for the first dead point is formed and an average position is calculated by dividing by N.  A similar average position is formed for K cycles, where K is smaller than N and passed to a processing device (A). The processing device is a display that shows K digitally - and N as well. (Two workpieces (W1,W2) are moved continuously towards and away from one another under the action of the hydraulic pressures piston and cylinder (ZY). A travel sensor (Wa) detects workpiece position and is coupled via converters (V1,V2) to the arranging circuitry (SG,DG). ADVANTAGE - Detects incorrect positioning.

Title: Super glue package - designed at foil bag for bursting by hammer blow
Inventor: WIEDENHUES MARIANNE
IPC: C09J5/00
Filed: 1990-05-04
Abstract: Superglue for instant adhesive action comes at present in tubes where it soon dries out or clogs the opening. It is therefore suggested to pack it in foil pads which burst when squeezed Multiweb extrusions are e.g. fixed to concrete ceilings at present by nails, gypsum or hot melt. The operation is speeded up and simplified, if such pads are placed between extrusion and concrete ceiling and squeezed to burst by a hammer blow. USE/ADVANTAGE - For time consuming and labour intensive installations, e.g. of cables, concrete ceilings. This saves time and makes a reliable job.

Patent DE-4039741-A1 (DE)
Title: Rolling pipes with control of temp. distribution - using measured geometry at rolling mechanism outlet to control local heating and/or cooling using on=line processor
Inventor: THIEVEN PETER DIPL ING
IPC: B21B17/14
Filed: 1990-12-10
Abstract: The method of rolling pipes involves setting a desired temp. distribution in the roll material before and/or during the rolling process. The temp. distribution varies the shaping resistance of the material region by region. The pipe's geometric characteristics to be influenced are measured at the outlet of the mechanism and fed to a control loop contg. a demand-actual value comparator, a real time processor and signal convertor. The actual-demand difference is processed into a correction value using theoretical data. The converted correction value is used for local adjustment of the temp. distribution in the material before it enters the rolling mechanism. ADVANTAGE - Enables local temp. distribution of pipe material to be adjusted by local heating and/or cooling.
Patent DE-4106399-A1 (DE)
Title: Watchdog method for interrupt processing in microcomputer systems - has bistable or counter circuits with logic to combine interrupt request with output to indicate fault
Inventor: WIEGAND HERMANN-JOSEF DIPL ING
IPC: G06F13/26
Filed: 1991-02-28
Abstract: The interrupt watchdog circuit has a minimum arrangement that consists of a single bistable (BK) with negative logic operation. The reset for the bistable is controlled by an OR gate (1) that receives a service signal (ISERV) and a reset input (RES). The set input (5) receives the interrupt request (IREQ). In order to generate a fault alarm condition the request signal is combined with the output of the bistable in an OR gate (2), such that both inputs have to be low before the alarm (F) is generated. The process may be expanded for multiple inputs via a counter instead of a single bistable. ADVANTAGE - Provides checking of interrupt conditions.

Title: Measuring mean period duration of pulse train - forming integration time value, corresp. to integration time, by adding preset measuring time and rest time value
Inventor: GRIESBAUM WILHELM DIPL ING
IPC: G01R23/00
Filed: 1991-04-22
Abstract: The pulse train (Is) pulses are counted during an integration time period. An integration time value, corresp. to the integration time period, is formed by a summation of a preset measured time period time value (Zw) and a rest time value (Re). The integration time values equals the time period interval up to the arrival of the next pulse of the train. The period duration is determined by division of the integration time value by the number of pulses (Su) counted during the integration time period. In application with an A/D converter a measured magnitude (Um) is converted into a proportional frequency of the pulse train. USE/ADVANTAGE - Voltage frequency and a-d conversion in process automation system, with rapid measuring of period duration of pulse train.

IPC: B62D21/04
Filed: 1991-08-29
Abstract: The frame 1 for an agricultural trailer consists of a narrow box-shaped longitudinal carrier 2 whose relatively narrow width remains the same over its length and whose relatively large height varies, with the greatest height being present in the region of the wheel axle(s). The longitudinal carrier 2 is connected at the top at its two ends to a front body carrier 3 and a rear body carrier 4 and on its two sides to mutually aligned axle funnels 14, 15.
