Patent DE-4330749-A1 (DE)
Title: Device for measuring the oxygen partial pressure in a gas mixture
Inventor: GERBLINGER JOSEF DR
IPC: G01N33/00
Filed: 1993-09-10
Abstract: Fast gas sensors based on semiconductor metal oxides are particularly suitable for cylindrically selective  lambda -control. Since, in particular, strontium titanate reacts very sensitively to chlorinated hydrocarbons and chlorine gas, these exhaust gas components should not come into contact under any circumstances with the metal oxide layer, which is only a few  mu m thick. A unit (6) which interacts with chlorine is, according to the invention, connected upstream to the oxygen detector (5). This unit contains, in particular, a metal or ceramic body elastically mounted in a housing, which body is pierced by a multiplicity of mutually parallel flow channels and is coated with a material (Ag, Co, Pd) that reacts with chlorine. <IMAGE>

Title: Inductive proximity switch
Inventor: TIGGES BURKHARD
IPC: H03K17/95
Filed: 1993-09-27
Abstract: To lower the inherent power requirement in an inductive proximity switch (1) which has an oscillator (13), which can be influenced by a trigger (12), with an evaluating circuit (14) for the oscillator state, and, in particular, to keep this inherent power requirement so low that, especially in the case of proximity switches in two-wire technology, a wrong switching-on of these proximity switches is reliably prevented when the load is not connected, the oscillator (13) in the proximity switch according to the invention, when the load switch (10) is not switched on, is fed with a current which is only sufficient for exciting the oscillator (13) for short cycle times (Tk) after a capacitor (19) has been charged up, whilst the load current for supplying the oscillator (13) is made available when the load switch (10) is switched on. <IMAGE>

Filed: 1994-01-20
Abstract: A wet press section for a paper machine has a smooth roll (1.1) touched by the paper web forming a first roll gap (1) with a first counter roll (12). It forms a second roll gap with a second counter roll. A continuous and absorbent felt (F1) runs together with the paper (B) through the two gaps, successively. The second counter roll is a suction roll (3) with an internal stationary sealing support. A second continuous felt (F2) takes over the web (B) from the first felt (F2) and guides it through a third gap. Pref. the smooth surface that is in contact with the paper (B) in the first and the second roll gap represents a rotating press belt. A third roll gap is formed by two press rolls. The third gap associated with the second felt (F2) is part of a longitudinal gap press (II) and the second felt (F2) is the sole felt of this press. ADVANTAGE - The unit eliminates an elongation of the paper while the dry content of the paper is not adversely affected.

Title: Thread end deposition system for flat can filling station
Inventor: KRIEGLER ALBERT
IPC: B65H67/04
Filed: 1994-05-13
Abstract: The deposition system regulates the relative spacing between the mouth (15) of a turntable (12), a separator (18) and the flat can (1), to control the position of the thread end after filling the flat can and the length of the thread end.Pref. the mouth of the turntable is adjusted relative to the stationary position (D) of the flat can, so that the obtained thread loop at the end of the relative displacement of the flat can lies at the centre of the flat can end.

Patent DE-4425085-A1 (DE)
Title: Wristwatch
Inventor: KIEFER ROLAND
IPC: G04B37/14
Filed: 1994-07-15
Abstract: A wristwatch having an inner housing (11) of metal and an outer housing (1) of stone is characterised in that the inner housing (11) has a radial spacing from the outer housing (1) in a thickness region of the watch starting from the underside and two webs (17) are mounted in the gap for attaching the wrist strap to the inner housing (11), to which webs two downwardly open shallow recesses (7) in the outer housing (1) lead from both sides. There is room in the gap for the thickenings which, together with the webs, form the wrist strap lying double in each case. The two shallow recesses leading to the webs only need to accommodate the wrist strap. With a still sufficient strength of the outer housing, there results a concealed attachment of the wrist strap to the inner housing which is unproblematic in terms of strength. The webs (17) are curved, but with a lesser curvature than the gap. They are mounted on a flange (14) of the inner housing (11), which flange has cutouts, bridged by the webs (17), in the continuation of the recesses (7) in the outer housing. <IMAGE>

Patent DE-4435590-A1 (DE)
Title: Protector for laryngeal area during head or neck operations
Inventor: LOHMANN FRANK
IPC: A61B90/00
Filed: 1994-10-05
Abstract: A pressure sensor (1) is attached around the end of an endotracheal tube just prior to the sealing cuff. The pressure sensor can be a circular two wire sensor or a split wire system (7). The wires (8) from the sensor lead to a pressure monitor which can give a digital or an analogue reading together with an alarm function. When the endotracheal tube is in position and the surgeon begins to operate in the neck area he may encroach upon nerves connected to the larynx. This happens in between three and ten percent of all operations in the head or neck area and if the nerve is damaged can lead to loss of normal speech and a narrowing of the airway which leads to shortage of breath for the patient. If the surgeon is operating in the area of the N Laryngeus, pressure will be exerted on the nerve and an optical and acoustic alarm will sound.

Patent WO-8703772-A1 (WO)
Inventor: STENZEL OTTO
IPC: H05B7/152
Filed: 1986-11-29
Abstract: Un dispositif sert à régler l'écart entre une électrode de fusion (62) et la surface de matériau fondu (61) dans un four à chauffage direct par arc sous vide. On part du fait que les courts-circuits provoqués par des gouttes de matériau fondu entre l'électrode de fusion (62) et la surface du matériau fondu (61) donnent une indication sur l'état de l'électrode. La fréquence moyenne d'égouttement est à peu près une fonction linéaire de la longueur de l'arc électrique, c'est-à-dire le taux d'égouttement est en rapport hyperbolique avec la longueur de l'arc électrique. Afin d'obtenir dans ces conditions un réglage rapide, on applique à un dispositif de réglage (84) de la fréquence d'égouttement un signal qui correspond à la différence entre la valeur inverse d'un signal de taux d'égouttement formé par un générateur (80) de valeurs moyennes et une valeur de consigne fréquence d'égouttement.

Patent WO-9414615-A1 (WO)
Inventor: SCHNEIDER GEORG
IPC: B41F30/04
Filed: 1993-12-14
Abstract: In a device for securing and clamping a rubber web, printing web or printing plate on a cylinder of a rotary press, the purpose is to ensure that the printing web is uniformly clamped over its entire width as a result of the torqueless rotation of the clamping spindle which can also provide uniform clamping during operation. This is done according to the invention in that the spindle has teeth around its periphery which mesh with that of racks arranged to be movable transversely to the axis of rotation of the spindle. The racks can be driven by a spring-loaded adjuster.
Patent WO-9422006-A1 (WO)
Inventor: KUNATH CHRISTIAN
IPC: G01N27/414
Filed: 1994-02-21
Abstract: The subject of the invention is a semiconductor component for measuring ion concentrations, in particular an ISFET (ion-sensitive field effect transistor). The semiconductor component consists of a substrate and a sequence of layers arranged frontally thereon, with the component having one or more ion-sensitive layers and possibly other sequences of layers arranged in a thinned region to the back of the substrate. The ion-sensitive layer here is designed as the gate of a field effect transistor. The source and drain regions of the field effect transistor as well as the frontally situated sequence of layers are electrically insulated from the back side of the substrate by a buried insulating layer.  Due to the structure of the component, the contact connections with the electronic elements can be situated only at the front of the component. The geometric configuration of the ion-sensitive membrane and the contacts provide a simple and secure encapsulation of the semiconductor component which protects defined chip regions from electrolytic corrosion. The semiconductor component is adapted for encapsulation in a carrier which is coated with strip conductors that are electrically connected with the electrical contacts of the semiconductor component. The carrier is structured in such a way that frontally the upper surface of the semiconductor component is entirely covered by chemically resistant materials.
