Title: AF switching interference suppression circuit for diversity reception - employs either IF or HF wiring from diversity processor to receiver for transmission of suppression pulse between selectors
IPC: H04B7/08
Filed: 1992-02-14
Abstract: The diversity processor (1), incorporating an antenna switch (15), interference detector (10) and selector (2), is linked to the receiver (4) by an HF line (6) and an IF line (5). Interference in the audio frequency band due to antenna switching signals (3) is suppressed by application of a switching pulse (16) to the selector. At the far end of the IF line another selector (7) forwards this pulse to an LF interference suppression circuit (8) inserted between the FM demodulator (17) and loudspeaker driver. In an alternative embodiment the HF line is used instead for this purpose. USE/ADVANTAGE - In multi-antenna scanning diversity systems on motor vehicles, necessary wiring between diversity processor and receiver is utilised for suppression without detriment to the functioning of system.

Title: Method of rolling honing bevel gears as well as a tool and apparatus for carrying out the method
Inventor: STADTFELD HERMANN J PROF DR
IPC: B23F19/00
Filed: 1993-04-24
Abstract: Bevel and hypoid gears with precut teeth and any longitudinal tooth shapes are hard-finished with this continuous method. The tools provided with a coating of mechanically resistant material are bevel-gear-like bodies which are simple to produce on conventional gear-cutting machines for bevel gears. In the process, the stock removal is achieved by spraying an abrasive medium between tool and work gear. According to the invention, the tool is derived from a virtual generating gear, in the interior of which it meshes, while the generating gear in turn meshes with the work gear. An additional rotary speed component of the tool brings about rolling of the tool by the engagement zone between generating gear and work gear, that is, past the work gear, as a result of which the contact between tool and work gear gradually comes about (feed movement). The change in the shaft angle between tool and work gear permits an infeed for the specific control of the chip thickness. The complicated spatial rolling movement of the tool in the process is converted according to the invention by a transformation into a simple plane axial displacement in combination with a shaft-angle rotation, which according to the invention is realised by a finishing machine with only three moving machine axes and two machine spindles. The method can be carried out in the case of all gear tooth systems which can be lapped, by additional movements of the machine axes all corrections of contact-pattern form, size and position are ...

Patent DE-4317123-A1 (DE)
Title: Special flipflop
IPC: H03K3/356
Filed: 1993-05-21
Abstract: The flipflop according to the subject matter of the invention is a special flipflop in which two additional transistors are used to avoid the drive current partially flowing away directly to the zero-voltage potential. This is achieved in that the current is dissipated to the zero-voltage potential via an additional path on the komtra [sic] side. Thus, in the case of the flipflop according to the subject matter of the invention, an additional transistor on the opposing side is driven with high potential, and the high potential in this region is thus reduced to low potential. <IMAGE>

Patent DE-4327453-A1 (DE)
Title: Paraglider
Inventor: SCHEEL MARTIN
IPC: B64D17/02
Filed: 1993-08-16
Abstract: The sailcloth cup (1) has a plurality of cells (2) which are separated from one another by intermediate cell walls (3). The shape of a wing is maintained by the air which enters during flight through openings on the leading edge of the sailcloth cup (1) and produces an internal pressure. The internal pressure prevailing in the cells (2) causes the outer cell walls (5) to curve outwards as a result of which the sailcloth cup (1) normally has a corrugated surface. In order to avoid this corrugated surface, particularly on the top of the sailcloth cup (1), the corrugation troughs are in each case bridged by a cover (6). As a result of this cover (6), the surface of the wing formed by the sailcloth cup (1) is smooth. The airflow therefore runs optimally here, as a result of which the lift of the paraglider is improved. <IMAGE>
