Patent DE-3901304-A1 (DE)
Title: Mechanical roller-blind seal
Inventor: LEMMEN BERNWARD
IPC: E06B9/17
Filed: 1989-01-18
Abstract: The invention relates to a mechanical roller-blind seal which largely closes off the outlet gap for the roller-blind shutter with respect to the outer atmosphere. This takes place by means of a closure moulding which, in its effective position, bridges the gap between the outer surface of the roller-blind shutter and the opposite bounding surface, at least over sub-regions of its longitudinal extent. Said closure moulding which, in its effective position, bears on the roller-blind shutter may additionally serve as an anti-theft safeguard since, when the roller-blind shutter is raised, it engages in between two adjacent mouldings of the roller-blind shutter and thus effects positive locking.
Patent DE-3902947-A1 (DE)
Title: Device for adjusting drive components to a zero-position bit pattern of the d.c. motors driving them
Inventor: GERKEN HEINER DIPL ING
IPC: B41J1/24
Filed: 1989-02-01
Abstract: In program-controlled typewriters or office machinery of a similar design it is necessary for the type wheel (7), the printing mechanism carriage (6) and the cam (35) which lifts the ink ribbon and/or the correction ribbon to assume a specific position with respect to the bit pattern driving the d.c. motors (47, 8, 43). This is necessary if exact adjustments of the type wheel (7), of the printing mechanism carriage (6) and of the cam (35) are to be ensured. The invention is based on the object of providing a device which is easy and cheap to manufacture and has the function of adjusting all the drive elements which can be driven by d.c. motors to a zero-position bit pattern of the d.c. motors driving them. This object is achieved in that a locking element is arranged on the printing mechanism carriage (6) and, during the movement of the printing mechanism carriage (6) into the outermost left edge position, can be positioned with locking noses (21, 23) in the active area of stops (20, 34) arranged at the drive components (9, 35) in order to lock the d.c. motors (8, 43) driving the drive components (9, 35). The adjustment device according to the invention permits, by means of a single locking slide, a rapid and simple adjustment of the type wheel and of the cam to the zero-position bit pattern of the d.c. drive motors (8, 43) driving them. <IMAGE>
Patent DE-3907873-A1 (DE)
Title: Arrangement for indicating the time
Inventor: HEINDL EDUARD
IPC: G04C17/00
Filed: 1989-03-10
Abstract: For indicating the time in the case of analog timepieces, it has hitherto been necessary to use an hour hand and a minute hand, so that it is possible to read the time accurate to a minute. An arrangement having a vernier scale on the dial and a circumferential hour disc with openings for uncovering the minute marks makes it possible to read the time accurate to a minute and does not require a minute hand which is mechanically separate from the hour hand.

Title: Sewing machine data input - takes coordinate data from scanner for initial needle position to be replaced if data matches second position already inserted
Inventor: SHIGETA KATSUNORI
IPC: D05B19/08
Filed: 1990-01-24
Abstract: To build up the required stitching data, for a sewing machine, coordinate data are read in sequence for a coordinate input unit, for the initial needle position data to be calculated accordingly. Should the initial needle position data fall within a given range against second needle position data already inserted into the system, then the initial position data are replaced by the same data as the second needle position data. If new data matches existing data, a selection command is generated for a matched position to determine if the new data are within the range of the existing data or not, and the replaced data are stored in memory as control data for the automatic sewing machine. The coordinate data input unit has a scanner (10), and replaced data are shown on the display (26) with a different indentity mark from other pattern data. The matching initial needle position data with existing data are rendered inoperative, so that the remaining initial position data lie outside the preceding zones and the position selection command is maintained when the first needle position data are made ineffective and displayed.
Patent DE-4007548-A1 (DE)
Title: Emission control for engine - by digital lambda regulation with responsive computation of exhaust state using engine loading
Inventor: ZIMMERMANN JUERGEN DIPL PHYS D
IPC: F02D41/14
Filed: 1990-03-09
Abstract: The precise determination of the lambda value of the exhaust gases is possible by measuring the actual load of the engine and computing a corresp. increment level. This increment is added to or subtracted from the reference level of the lambda value after suitable integration. The computation time refers to two engine revolutions, or is evened out over two cylinders. It eliminates the conventional error due to differences in dwell time of the gases in the cylinders, e.g. at different engine speeds. ADVANTAGE - Improved emission control, simple processor control.
