Patent DE-4337596-A1 (DE)
Inventor: GELING HELMUT
IPC: D07B3/02
Filed: 1993-10-28
Abstract: The invention relates to a process and device for producing steel cord, in particular high tensile and ultra-high tensile strength cord. The aim of the invention is to provide for a high-quality production of in-out stranded wire with a core wire made of high tensile and ultra-high tensile wires, where large-scale spool fillings can be processed at an acoustic level of < 80 dB. This is accomplished in that a) the wires (8; 8') are drawn off at constant tension over the entire spool filling from mechanically brakable supply spools (2; 2') that are mounted essentially within a spool frame (1a) and that have a filling weight of > 50 Kg, and, through a glide and roll-off movement on a conical reversing sheave (7) at a single stranding point (9), the wires are stranded in a double twist to the structurally finished stranded wire (15); b) the structurally finished stranded wire (15) rotates about itself in passing through two synchronously rotating flyers (13a, 13b) at double the rotational speed of the flyers (13a, 13b); c) the individual wires (8; 8) are subjected to a predeformation before they pass into the stranding point (9); d) the structurally finished stranded wire (15) is subjected to a plastic deformation by overtwisting in the region between the stranding point (9) and the conical reversing sheave (7); e) the overtwist speed and the flyer speed are mutually adjusted at the same rotational speed ratio over the entire stranding process, including start-up as well as braking phase; f) to reduce its inner torsional tensions prior to being wound up, the stranded wire (15) is subjected to a defined increase in tensile force and to one or more overtwist and reforming processes and finally delivered at a constant take-up force to a controlled take-up stand (5).

Title: Solenoid valve for hydraulic brake system with feedback control
Inventor: VOLZ PETER DR ING
IPC: B60T8/42
Filed: 1993-11-18
Abstract: Hydraulic fluid flow to a valve seat (116) enters the valve through a restricted opening (130), into the intermediate space (117) of the piston (8), via a further restricted passage (129), partially converting the pressure energy at the restriction (130) into kinetic energy. The valve seat is opened and closed by an electromagnetically operated slider (11).  Under normal braking conditions, the hydraulic pressure is insufficient to compress the spring (7) and the pressure is transmitted to the brake through channel (3). With excess pressure applied the piston (8) closes against the seal (115), shutting off the flow through the hole (116). Flow is restored by operation of the solenoid and hence lifting of the slider.

Title: Regenerating active carbon@ grains in fluid bed
Inventor: BARTETZKO ANDREAS DR
IPC: B09C1/08
Filed: 1994-10-12
Abstract: Active carbon granules bearing organic pollutants are regenerated in a two-stage process. The cleaning process takes place within a closed fluid-bed water-driven reactor, in the lower section of which are noble-metal-coated electrodes inclined at 5-45 pref. 5-30 deg  to the vertical, and extending one tenth to one twentieth of the inclined reactor section. Within this section, oxygen bubbles are finely-generated by electrochemical means in a volume ratio of 2-500 with reference to the volume of the load-bearing carbon granules. Before the aerobic process is applied, particles which cannot be aerobically treated, are broken down so that they may then be subjected to biological processing. These processes include: (a) exposure to UV light; (b) the UV source is within the reactor; (c) the agent is introduced into the reactor after exposure to UV light, or ;(d) the fluid bed reactor is operated without additional oxygen until anaerobic treatment is no longer possible, when; (e) operation is changed to the aerobic mode, and aerobic microorganisms are introduced as required.

Patent DE-4439744-A1 (DE)
Title: Alarm switch lock with key recognition
IPC: E05B45/10
Filed: 1994-10-28
Abstract: In known mechanical alarm switch locks, after the mechanical tumblers have been overcome forcibly or by trickery the switching operation can be carried out without authorisation. Moreover, they usually cannot be adapted to existing door-locking systems. The new device is to be inexpensive and sabotage-proof and allow identical locking with existing locking systems. In the alarm switch lock, key recognition takes place in that electromechanical sensors sense the lift caused by the key bit on the tumblers of a conventional profile-cylinder lock. The sensing result is converted into switch-on or switch-off signals or alarm signals in an external electronic evaluation unit. Because the components of a conventional profile-cylinder lock are thereby integrated directly into a switching operation, forced attempts at sabotage lead simultaneously to the destruction of the switch-lock part and an unauthorised switch-on or switch-off of the alarm system is therefore no longer possible. On the other hand, the alarm is triggered directly. Furthermore, identical locking with existing locking systems is possible. The alarm switch lock is suitable for use as an electrical switch lock, particularly in alarm systems.

Filed: 1991-06-29
Abstract: Die Erfindung betrifft ein Verfahren zur Zweipunkt-Lambdaregelung einer Brennkraftmaschine mit Katalysator, das sich dadurch auszeichnet, daß die Regelung so ausgeführt wird, daß die Regelschwingungen zumindest in vorgegebenen Betriebszuständen eine möglichst große Amplitude aufweisen, jedoch nur so groß, daß es nicht zu Laufunruhe der Brennkraftmaschine kommen soll und die mittlere Konvertierungsrate des Katalysators um einen vorgegebenen Wert unter derjenigen Konvertierungsrate bleiben soll, die bei verringerter Amplitude bei stationärem Betrieb der Brennkraftmaschine erzielbar wäre. Dieses Verfahren zielt also nicht auf minimale Regelamplitude wie herkömmliche Zweipunkt-Lambdaregelungsverfahren, sondern es wird abhängig von der Konvertierungsrate des Katalysators immer eine solche Amplitude eingestellt, die für stationären Betrieb zu groß ist, um optimale Konvertierung zu erzielen, die jedoch schnelle Regelung und damit minimale Schadgasemission bezogen auf die Summe aller stationären und instationären Zustände zur Folge hat.
