Patent DE-3328179-A1 (DE)
Title: Ground-air parachute mine
Inventor: ANKER FRANZ
IPC: F41H11/04
Filed: 1983-08-04
Abstract: As is generally known, between 1940 and 1945 cities were destroyed by enemy bomber squadrons, because there was hardly any possibility of combating these. I intend very largely to prevent this, and mainly very low-flying attack aircraft, with my ground-air mine. Spherical mines similar to the water mines of the Navy are located in safety containers on the ground in front of an object to be protected. Also thereon is a roll of steel or plastic cable, in which a parachute is suspended at the start. A flat gas bladder with light gas (carrying gas) is suspended in this open parachute, so that, if desired, the parachute can be released at different heights by means of a solenoid. Now if an enemy aircraft flies against the cable, the erected parachute pulls the ground-air mine out of the safety container and strikes it against the assailant's wing. As a result of the detonation, the aircraft is damaged and crashes. In this way, one man can simultaneously release a plurality of ground-air parachute mines, but if necessary retract them individually again. Since the production costs of mini-mines of this type are very low and these also require only simple storage, they can be produced and stored in relatively large quantities.
Patent DE-3328432-A1 (DE)
Title: Exterior rearview mirror for motor vehicles
Inventor: KRAAS PETER DR MED
IPC: B60R1/078
Filed: 1983-08-06
Abstract: An exterior rearview mirror (10) for passenger vehicles has a main mirror (13) and a supplementary mirror (21). The mirror housing (15) of the main mirror (13) is attached in a spatially fixed manner to the vehicle (11) and can be swivelled in each case out of its spatially fixed position with a restoring effect in the travel direction (x) and in the opposing direction about two folding axes (A, B) of its main holder (12) which are parallel to one another. The mirror element of the main mirror (13) is held in its mirror housing (15) so as to be adjustably lockable in relation to the latter in a spatially articulated manner. At the same time, on the front of the mirror housing (15) facing away from the mirror element of the main mirror (13) a supplementary holder is attached which consists of a bearing bracket (18). In the latter, the bent, pivot pin-like insertion end (26) which is formed by the inner region of the holding arm (22) of the supplementary mirror is held in a swivellable and lockable fashion. The outer end of the holding arm (22) bears the supplementary mirror (21) on a spatial joint (33) whilst the insertion end (26), held in the bearing bracket (18), of the holding arm extends parallel to the two folding axes (A, B) of the main holder (11). The pivot pin-like insertion end (26) is bent in such a way that the bend (23) forms an angle ( alpha ) of at least 90 DEG  and is located above the upper edge (24) of the mirror housing (15). <IMAGE>

Patent DE-3339875-A1 (DE)
Title: Measurement transducer
Inventor: STEIN KURT DIPL ING
IPC: G01L7/08
Filed: 1983-11-04
Abstract: The hitherto known measurement transducers have the considerable disadvantage that they cannot be combined to form assemblies (a plurality of capsule spring elements) as a result of the poor dimensional stability of their construction, since the thin-walled design required there leads to unacceptable deviations in the linear profile of the elastic spring travel for measuring and control tasks. In order to obtain nonetheless certain long spring travels and certain high spring forces, special constructions were necessary which were of complicated design and yet were unsatisfactory in their operating behaviour. In order to create a measurement transducer which does not have these considerable disadvantages and can be used universally and cost-effectively, it is proposed that a plurality of cell bodies (2) be adapted to fit together in a pressure-tight manner to increase the spring force and the spring travel, the pressure being passed from one pressure space (24) to the other via a tubular extension (15, 17) which is connected on the one side to the diaphragm spring (3) and on the other side to the adjoining cell bottom part (9). <IMAGE>

Title: Toy weapon
Inventor: FACKLER GEORG-GERHARD
IPC: F41C3/08
Filed: 1984-01-05
Abstract: A toy weapon for the successive firing of caps has a spring-loaded hammer, which can be cocked and released via a trigger and has a percussion pin, and a strip of caps which can be transported by means of a transportation device through a guide in the toy weapon. The strip of caps has a multi-row, preferably a double-row, construction, the toy weapon having a number of hammers corresponding to the number of rows of the strip of caps, which hammers can be moved alternately into an operating position and a rest position by means of a single trigger, with the interposition of a combined cocking, release and transportation device. As a result of this construction, it is possible to increase by a factor of two or more the number of caps which can be fired, while maintaining the length dimension of the toy weapon.

Title: Stone slab working machine for producing inside and outside contours on the edges of stone slabs
Inventor: WESELY DIETER LUDWIG ING GRAD
IPC: B23Q35/10
Filed: 1984-05-21
Abstract: Stone slab working machine for producing inside and outside contours on the edges of stone slabs using end-milling cutters in the copy-milling method. The sensing roller rolling off on the cutting pattern is positively driven and is pressed against the cutting pattern by force-generating means with such force that sufficient force to advance the milling tool is applied by the frictional force acting on the sensing roller. The tool holder and its drive and the sensing roller and its drive are arranged on a support which is smoothly guided on a freely pivotable pivot arm, so that the support and the pivot arm are pulled along by the sensing roller rolling off onto the cutting pattern so as to follow the contours of the latter.

Title: Method and device for negative feedback of a loudspeaker
Inventor: WIEMANN LOTHAR
IPC: H04R3/00
Filed: 1984-07-17
Abstract: For more effective matching of the actual signals emitted by a moving-coil loudspeaker to the ideal signals fed to the loudspeaker, a measured value transmitter 15 connected to the diaphragm 17 is provided which supplies an actual signal corresponding to the movement of the diaphragm to a comparator 3. In a re-adjustment amplifier 7, a corrected ideal signal, as opposed to the ideal signal from which it is derived, is generated by means of the differential signal supplied by the comparator 3, said corrected ideal signal being fed to the loudspeaker 11 and supplying an actual signal emitted by the diaphragm 17 which largely matches the ideal signal. <IMAGE>

Title: Protective circuit for a power transistor through which the load current flows
Inventor: SCHIRMER KLAUS DIPL ING
IPC: H02H7/20
Filed: 1984-09-13
Abstract: The circuit has a control circuit limiting the drive to the power transistor. The invention consists in that the control effect is dependent both on the load current and on the voltage dropped across the controlled current path of the power transistor. This is achieved by the fact that a control circuit is driven via in each case one resistor from both main electrodes of the power transistor.

Title: Circuit arrangement for transmitting criteria characterising the subscribers of an exchange
Inventor: BIRAGHI GIORGIO
IPC: H04Q3/72
Filed: 1984-11-16
Abstract: A particularly simple circuit arrangement is described with which criteria, for example for identifying a subscriber of a public telephone exchange, can be transmitted via the meter wire even if it is impossible, as in the case of dual-connection subscribers, to decouple the meter of the subscriber from the meter wire, using a diode. The reception of the criteria is time-controlled by a string of very short pulses. The meter is decoupled from the meter wire by the high impedance which it has during the initial phase immediately following the occurrence of a pulse, due to its internal inductance. <IMAGE>
