Patent DE-2513611-A1 (DE)
Title: Antenna for primary and secondary radar - has inner dipoles connected to distributor and outer dipoles operated parasitically
Inventor: UHLMANN MANFRED
IPC: H01Q21/28
Filed: 1975-03-27
Abstract: The combination antenna for primary and secondary radar equipment has a horn radiator connected by an elongated extension to a curved reflector for the primary circuit, and has a set of dipole reflectors extending towards the reflector for the secondary circuit, with a distribution circuit positioned behind the dipole reflectors. Instead of this distributor being located at the centre and being connected to all four dipole reflectors, thus reducing the distribution angle, the distributor is connected to the two inner dipole reflectors, and the outer reflectors are operated parasitically. The latter are connected by short or open circuited conductors of a length corresponding to a desired phase of the reflectors.

Title: Airborne radar network used in navigation and mapping - produces display of overflown land profiles for a range of azimuths
Inventor: LEYSIEFFER HANS DIPL PHYS DR
IPC: G01S13/935
Filed: 1975-09-29
Abstract: A directional aerial (A) is used which produces a narrow pulsed radar beam which scans a section of land roughly in the direction of flight but in a particular direction selected by the aerial director. The beam spans 45 deg. of elevation, but is very narrow in azimuth, and the returning pulses are processed by a network of amplifiers, switches and filters and fed to an evaluation unit before display on a tube. The display may be made stereoscopic by using the input from two aerials and displaying the output on a double polarized display, viewed through suitable polarized spectacles. The evaluator unit consists of a variable clock frequency digital filter incorporating inverse cosine characteristic elements.

Title: Guide rollers for regulating axial position of web - are installed in hinged frame for angular adjustment
Inventor: KUESTER WOLFGANG
IPC: B65H23/02
Filed: 1975-10-07
Abstract: The transport rollers (2) for continuous web material are mounted on a common support frame (1) which allows the rollers to be moved in two perpendicular planes. A sensor fork (5a) which detects the position of the band edge, is carried by a cross slide assembly (8-15). Any deviation of the band edge, transmitted to the cross slide by the sensor fork (5a) causes the support frame to correct its angular position in relation to the band. The axial position of the moving band on the transport rollers can thus be maintained.

Title: Automatic hydromechanical torque converter - has two crank drives for output shaft and valve spindle for stepless output production
Inventor: WALZER RUDOLF
IPC: F16H43/00
Filed: 1975-10-29
Abstract: An automatic torque converter has a hydraulically driven twin cylinder which has a common piston rod. The cylinders are in line so that when one piston outstrokes, the second piston is on its return stroke. A crank lever drive is linked to the piston rod and to a gear wheel which in turn drives the output shaft. A screw spindle is used to regulate the travel of the crank drive in relation to the required output torque, thus stepless output adjustment is obtained. A second crank drive is geared to the driving crank and its output operates two slider valves with which the two pistons are controlled.

Title: Acoustic warning for direction flasher - has threshold coupled the delay linked to headlamp warning if ignition switched off
IPC: B60Q11/00
Filed: 1975-11-05
Abstract: The transistorized buzzer circuit is operated by a threshold switch coupled to a time delay circuit. This is started by the direction flasher current, and operates the warning if the flashers are not cancelled after a set time interval. The circuit also monitors the headlamp current, and operates the warning if the light are left on with the ignition switched off. The same alarm circuit is used for both modes, and can be a small, compact module which plugs into the two threshold circuits. The warning is loud enough to be heard above the vehicle noise. It prevents the driver from driving if the self cancelling control has not tripped.

Title: Digital electrical measurement device - has comparator and counter in feedback circuit with common measurement and reference input
Inventor: MARINGER ALBERT ING GRAD
IPC: G01R19/255
Filed: 1976-06-11
Abstract: A digital electrical measurement device working with feedback to compare a measurement voltage with a reference voltage in a comparator has a counter input controlled by the comparator receiving clock pulses. A d-a converter produces the reference voltage corresp. to the counter contents. The device is designed for reduced insensitivity to supply voltage variations. The supply current required for measurement with passive components is derived from the same source which provides the current for feedback to the comparator. The converter consists of current sensing resistors (RD1-RDn) connected singly or in combination via switches (TI-Tn) in series with a summing resistor (RS) and in parallel with the voltage source (U). A similar sensing resistor (RM) detects the measurement current.

Title: Oven for thermal processing of semiconductor wafers - has screw spindles carrying plane parallel wafers through heating tube
Inventor: GUECKEL HELMUT DIPL PHYS
IPC: B65G33/06
Filed: 1976-07-02
Abstract: The oven, for thermally processing circular semiconductor wafers, consists of a tube (1), with a circular or rectangular cross-section and made of either quartz of e.g. silicon, through which the s-c wafers (4) (e.g. silicon) travel. The wafers are conveyed along the tube by parallel screw spindles (2) distributed around the circumference of the plane-parallel wafers inside the tube. Each wafer engages the threads of the spindles with its edge and moves along as the spindles rotate. The pitch of the threads is chosen to match the rate at which the wafers have to pass through various parts of the tube. The spindles are made of the same material as the wafers, e.g. silicon.
Patent DE-2637415-A1 (DE)
Title: Buttonholing attachment for sewing machines - requires only one manual operation to sew locking stitches and one side
Inventor: KASUGA NOBORU
IPC: D05B19/00
Filed: 1976-08-19
Abstract: The arrangement, with a main shaft lifting and lowering the needle bar, has the main shaft coupled to a cam disc shaft and driving it at a lower speed. On the cam shaft there are cam discs which rotate with it, and on a parallel shaft there are two cam followers movable between a position in which they are out of contact with, and a second posn. in which they are engaged with, the cam discs. A positioning device can be moved between a posn. of rest in which the setting for the sewing of the buttonholes can be chosen, and a working posn. in which the mechanism for sewing the buttonholes is driven. There is a releasing device for the cam followers which turns with the cam disc shaft from a starting posn. when the positioning device is working, and returns the cam disc followers from the second posn. to the first posn. at predetermined levels. A displacing mechanism for the cam disc follower support mechanism is also provided, by means of which the releasing mechanisms for the cam disc followers are turned intermittently so as to displace the cam disc followers relatively to the majority of the cam discs, on each occasion when the releasing mechanisms move back the cam followers from the second to the first posn. A stop mechanism for interrupting the interaction of the releasing mechanisms for the cam followers and the displacing mechanism for these, interrupts in definite posns. so as to stop the displacer mechanism for the cam followers, each time the releasing mechanisms for the cam followers discontinue releasing them. There is a clearing mechanism to release the releasing mechanisms for the cam followers and free the cam disc shaft, which the releasing mechanisms for the cam disc followers put back into the original starting posn. and there are also actuating devices for moving the positioning devices between the resting and the working posn. With one setting a locking stitch and the right or left hand side of the buttonhole can be sewn so that efficiency is increased. Change over from the base stitch pattern to buttonhole stitch can be effected quickly and accurately. During the sewing of buttonhole or ground stitch patterns, the setting can be suppressed so as to prevent unwanted stitches deforming already executed stitches.
