Patent DE-3609402-A1 (DE)
Inventor: POLLAK HERBERT DIPL PHYS DR
IPC: G01N27/416
Filed: 1986-03-20
Abstract: In the method according to the invention of producing electrochemical gas sensors having at least one measuring electrode consisting of metal sheet and one counterelectrode, optionally an additional reference electrode, and also a gel electrolyte between measuring and counterelectrode, the gel electrolyte material is first subjected to a vacuum treatment for the purpose of degassing, and then to a polymerisation process. Only then is the metal sheet for the measuring and/or counterelectrode applied to the surface of the polymerised gel electrolyte. Because of the precise, uniform and continuous contact between the electrodes and the gel thereby achieved, the sensitivity, the reproducibility and the long-term stability can be substantially improved and the response and decay times of the gas sensors appreciably shortened. The production method can be optimised still further by applying a plastic film to the surface of the gel electrolyte before the polymerisation process. <IMAGE>

Patent DE-3616079-A1 (DE)
Title: Capacitive incremental length measuring system
Inventor: KOLLER ROMAN
IPC: G01D5/245
Filed: 1986-05-13
Abstract: The invention relates to a capacitive incremental length measuring system, in which a plate capacitor is used. Both at the stationary plate portion of the capacitor and at the plate portion of the capacitor which is displaced with respect to the stationary plate portion, the capacitive plate surfaces of said capacitor which are used for the purpose of length measurement exhibit surface elements which cause periodic variations in the capacitance in incremental scale units of the measurement path and which are connected together for each plate. This measure, which is to be regarded as the essential feature of the solution achieved by the invention, has the advantage, by contrast with designs of plate capacitors known from the prior art, that despite a short incremental point spacing the plate capacitor has available for evaluation a large variation capacity which can be effectively evaluated. The design of the plate capacitor as mutually displaceable threaded profiles is explained as a particularly preferred embodiment both for linear and for radial length measurement. Fig. 9 is proposed for the abstract for publication purposes. <IMAGE>

Title: Process for the lead sealing and closing of filling or pouring connection pieces on containers and container closure
Inventor: SIEPE FRANZ JOSEF
IPC: B65D51/20
Filed: 1986-06-28
Abstract: The invention relates to a process for the lead sealing and closing of filling or pouring connection pieces on containers after filling, especially on plastic canisters with a closing cap, and to a container closure for carrying out the process. By means of the invention, a simple and cost-effective operating mode and procedure for the lead-sealed closing of containers is presented, the lead sealing and the closing taking place in one operation. The customers or fillers of the canisters thereby have the advantage of being able to automate the lead sealing of the canister and the screwing on of the closing cap in an especially cost-effective way. Thus, the lead seal is first connected to the closing cap and, after the filling of the container, the closing cap together with the lead seal is attached as a unit onto the canister, after which the lead seal remains in the container orifice when the closing cap is removed.

Patent DE-3715373-A1 (DE)
Title: Radiant tube
Inventor: SEIBERT HANS-DIETER
IPC: F23C9/00
Filed: 1987-05-08
Abstract: The radiant tube contains, in an outer tube that is closed at one end, a burner head of a orifice-type mixed burner and a coaxial inner tube that surrounds the flame generated at the burner head and extends to near the closed end of the outer tube; together with the outer tube, it forms an annular chamber for carrying away the waste gases from combustion. By contrast with known radiant tubes, the novel radiant tube, is intended to reduce nitrogen oxide formation during combustion of the fuel and nitrogen oxide emissions with the waste gases from the radiant tube, as well as to have more even temperature distribution over the length of the inner and outer tubes. For this purpose, a combustion-chamber tube with essentially the same diameter as the burner head and the inner tube abuts on the burner head; its end that is connected to the adjoining inner tube is restricted by a partition to the diameter of a jet pump nozzle that ends essentially concentrically in the inner tube. That area of the circumference of the inner tube which essentially surrounds the outlet of the jet pump nozzle is provided with penetrations through which waste gas from the annular chamber circulates, and is added to the flame jet emerging from the nozzle, which is not yet completely burnt up. <IMAGE>

Title: Arrangement for storing defined data in a memory of an electrical device
Inventor: WENTE WALTER DIPL ING
IPC: G11C5/14
Filed: 1987-05-27
Abstract: In an electrical device, which is fed by a mains voltage, it is necessary to ensure that if the mains voltage fails in the case of a malfunction, defined data is stored in a memory (SP), and in particular that the memory (SP) is reliably erased. The electrical device (G) includes a generator (GE) which is driven mechanically by a driving device (A). In the case of a malfunction, the driving device (A) activates the generator (GE), to generate an operating voltage (U) for the memory (SP) and a memory control part (SA), so that defined data can be stored in the memory (SP). The arrangement can be used where a defined memory content must be set in the case of a malfunction, and in particular where the memory (SP) must be erased. <IMAGE>
