Patent DE-2651607-A1 (DE)
Title: Motor vehicle window lifting mechanism - has crank pin and gear wheel with projections for operation
Inventor: JAKOB WILLI
IPC: E05F11/50
Filed: 1976-11-12
Abstract: The window lifting drive is used for operating sliding windows in motor vehicles. Rotating movement is transmitted to a gear wheel by a crankpin. This wheel actuates the lifting mechanism. The crank pin and gear wheel have projections which ensure driving connection between these two components. The window is lifted by a device whose projections have a relatively large cross-section, yet the mechanism itself remains compact. The gear wheel (3) has two projections which have different lengths in the circumferential direction. The production tolerances are such that the crank pin projection (1a) in lifting direction is in contact with the longer gear wheel projection (3a) by means of an end of a brake spring (4).

Title: Throttle responsive vehicle automatic transmission control - has self cancelling low gear switch pressed manually for high load start
Inventor: BURNETT STANLEY FREDERICK
IPC: F16H59/08
Filed: 1977-01-28
Abstract: The automatic transmission control sets the gear ratio in response to signals relating to throttle setting, output shaft speed, road speed, engine speed and the operation of a kickdown control. In order to provide extra torque control a further switch can be operated so that a lower gear than normal is set, for smoother torque control. This enables the vehicle to start in first gear, rather than in second, and is used for smooth control in dense traffic or for towing. The low gear switch is self cancelling and has to be pressed every time a low gear start is required. Gear changes to higher gears, from the first gear, operate automatically as normal.

Title: Arc welding metals via open or closed seams - where arc is moved along seam by external magnetic field
Inventor: GANOWSKI FRANZ-JOSEF DIPL ING
IPC: B23K9/08
Filed: 1977-06-28
Abstract: Twometal workpieces or profiles are welded. The arc is moved in alternate directions (a,b) along the seam by a reversing the magnetic field or the welding current; and when the arc reaches the end of its travel in one direction, it creates a signal causing the reversal, so the arc moves in direction (b). A homogeneous magnetic field may be used along the seam; or one or more magnets may be moved along the seam. A further alternative is to use a row of magnets switches in sequence or with alteration in their amplitudes. The speed or frequency of the reversals may be varied. The pref. appts. includes a photocell located at each end of theseam and creating the signal when the arc is picked up by the photocell. A magnetically moved arc can be used for open seams; and the process can be automated.

Title: Seed control during sowing by tractor - has sensor located in feed channel to detect any interruption in seed flow
Inventor: BALOGH BARNABAS
IPC: A01C7/10
Filed: 1978-04-12
Abstract: A monitoring system fitted to a seed sowing tractor enables a check to be continuously made on the flow of seeds into the ploughed furrow. The tractor ploughs multiple furrows by dragging a multiple share unit, with each share having a feeder channel (14) along which seeds (28) fall. A piezoelectric sensor (16) is continuously contacted by the flow of seeds and generates signals to an error detecting stage (18) on the plough. Any blockage or interruption in seed flow is immediately signalled such that the operator is aware of the condition and the specific feed channel involved.

Title: Opto-electronic receiver for remote control - has directional properties achieved by hollow conical lens in end of transparent rod leading to photodiode
Inventor: KELLER HERBERT ING GRAD
IPC: H04B10/114
Filed: 1978-05-09
Abstract: The opto-electronic device has a photodiode (2) mounted on a circuit board (1) and facing the end of an organic glass rod (3) of c. 6 mm in dia. A hollow conical lens (5) is located at the other end of the rod and reflects light (7) down through the rod to the photodiode by refracting it through 90 deg. The lens is formed by a conical polished hole in the end of the rod. The incoming light undergoes total internal reflection at the rod/air boundary of the lens. The advantage lies in providing directional receive properties.
Patent DE-2820328-A1 (DE)
Inventor: FISCHER ALBRECHT GEORGE PROF D
IPC: G06F3/147
Filed: 1978-05-10
Abstract: This series-parallel for column indicator and flat screen image comprises a stagger register (30) composed of several stages (31, 32, 33) each stage comprising two inverter stages (1/2; 3/4; 5/6) to which are applied two clock frequencies (f1, f2). Both frequencies (f1, f2) are equal but phase-shifted by 180` with respect to each other. The first inverter stage (1) of the register (30) is the data input. Each stage (31, 32, 33) of the stagger register has an output (A1, A2, A3) which is respectively connected through a column switch (7, 8, 9) and a check and hold switch (10, 11, 12) to a line accumulator (13, 14, 15). Each line accumulator (13, 14, 15) is coupled to a light segment switch (16, 17, 18). An electro-optical transducer (19, 20, 21) is connected to each segment switch.
Patent DE-2822269-A1 (DE)
Title: Automatic mask aligning system for semiconductor prodn. - uses opto-electronic scanner for grids on mask and silicon wafer, with results integrated and averaged as to intensity distributions
Inventor: DOEMENS GUENTER DR
IPC: H01L21/027
Filed: 1978-05-22
Abstract: Sets of orthogonal lines are formed on the mask and on the silicon wafer. Each of the two sets is then scanned opto-electronically to produce two intensity distributions. The intensity along each scan line is integrated. The results for adjacent scan lines are subtracted from one another and then processed digitally to produce pairs of peaks. The average of the peaks in each pair is taken. The location of this averge marks the centre of the gradual or blurred edge of a line in either of the two sets of lines. Thus the centre of the line, or the centre of the gap between lines can be located. Continuous averaging in this way reduces each set of lines to two crosses which, when aligned, ensure that the sets of lines are also aligned, and thus the mask and wafer as well. Alignment lines with unsharp edges on both mask and wafer can be scanned fully automatically, e.g. using a TV camera or a laser, with no loss of positioned precision due to the lack of contrast at the edge of the lines.
