Title: Web moisture content measurement - is contactless through an electrode over material in electrical field with probes to register resistance
Inventor: LOEBEL WILFRIED DIPL PHYS
IPC: D06B23/26
Filed: 1993-06-26
Abstract: The contactless measurement of the residual moisture content of a moving web, uses the material's electrical resistance with an electrode (1) in the electrical field, over the material, in a linear shape with HT conductivity, parallel to the line of web travel. It is between two earthed metal surfaces (2). A charge signal is affected, and its level and time behaviour is registred by two successive charge measurement probes (3, 4) over the web and a side probe (5). From the law of charge build-up in the field and the subsequent discharge, the electrical resistance and the associated residual moisture content is estabilished. Also claimed is an assembly where the surfaces of the probes (3, 4) are on a plane parallel to the web surface. A rotating and earthed perforated, slitted or bladed disc in front of the probes rotates towards the material to modulate the charge signals received by the probes. USE/ADVANTAGE - The system is for the mesurement of the residual moisture content in a web of absorbent material such as textiles of or with a content of regenerated or natural fibres, paper and photographic film. The contacless action eliminates problems associated with electrode contact, in a more reliable measurement action.

Title: Coaxial transmission with 3 secondary shafts
Inventor: THEBEN HENRIK DIPL ING
IPC: F16H1/22
Filed: 1993-09-01
Abstract: The invention relates to a spur-gear transmission with coaxially offset axes, having at least 3 secondary shafts (each with 2 rigidly secured gearwheels) which surround the input and output shaft in a star shape and transmit the torque from the gearwheel of the input shaft to the gearwheel of the output shaft. In order to achieve uniform load distribution between the individual toothings connecting the gearwheels of the input and the output shaft and the respective gearwheels of the secondary shafts, both the input shaft and the output shaft are not radially supported in the transmission but are supported in the corresponding gearwheels on the secondary shafts. Outside the transmission, the input shaft, which is connected rigidly or in torsionally elastic fashion to the engine shaft, is supported in the nearest radial bearing of the engine shaft. The output shaft, which is connected to the shaft of the machine, is supported in the nearest radial bearing of the machine. The toothing of the gears is furthermore of simple helical configuration such that the axial forces resulting from the tooth engagements are absorbed by thrust bearings arranged inside the transmission. An axial force (e.g. the propeller thrust) can be absorbed either by means of this thrust bearing situated inside the transmission between the gearwheels of the input and the output shaft or, alternatively, by means of a thrust bearing which is mounted separately or mounted on the transmission casing between the transmission and the machine ...

Patent DE-4333311-A1 (DE)
Title: Device for mixing gases in compressed-gas cylinders
Inventor: GROMBACH PETER
IPC: F17C13/00
Filed: 1993-09-30
Abstract: The invention relates to a device for intermixing gas compositions in compressed-gas cylinders. In CO2 impulse lasers it is normal practice to prepare the working-gas mixtures for the laser in a single gas cylinder in a ready premixed state for the operation. However, since the laser only requires small gas quantities for its operation, the gas cylinders are used over a very long period. Since the gas mixtures in the gas cylinder segregate according to their density on account of gravitation effects, difficulties arise after some time during the operation of the laser on account of unfavourable gas compositions. According to the invention, provision is made to provide the gas cylinder with heating at the bottom end. The heating produces a convection flow in the gas cylinder and thus constantly intermixes the gas. So that even larger quantities of gas can be effectively intermixed, provision is made to heat the gas cylinder at the bottom end and at the same time cool it at the top end. Larger quantities of energy can thereby be supplied for intermixing the gas of the gas cylinder. In this way, uniform intermixing of the contents of the gas cylinders is achieved. Gas lasers therefore receive a uniform gas mixture of constant composition over long periods.
Patent DE-4334681-A1 (DE)
IPC: F15B15/24
Filed: 1993-10-12
Abstract: A linear actuator, adapted especially for picking up and transporting workpieces, comprises a pneumatic, rodless cylinder (3) having a pair of driven elements (8, 16) mounted on opposite sides of its body. The first driven element (8) is directly connected to the piston (6) of the cylinder (3) via a sealed, longitudinal slot (5) formed in the cylinder body (1, 2) and the second driven element (16) is drivably connected to the piston (6) or first driven element (8) by a flexible drive band (24) that passes around rollers (20) mounted at opposite ends of the cylinder body (1, 2). The driven elements (8, 16) therefore move linearly in opposite directions to one other upon actuation of the rodless cylinder (3). The second driven element (16) may be fixedly secured to a stationary structure so that, upon actuation of the cylinder (3), the cylinder body (1, 2) itself and the first element (8) will simultaneously execute linear motion in the same direction whereby the first element (8), which may have a work piece gripping device mounted on it, will in effect execute double its normal stroke length. <IMAGE>

Title: AC ignition system imposing lower voltage stress on capacitor
Inventor: DAETZ MICHAEL DIPL ING
IPC: H03K17/13
Filed: 1994-03-23
Abstract: The oscillatory circuit has the capacitor (C) in parallel with the prim. winding of the ignition coil (Tr). The turn-on behaviour of the semiconductor switch (T) is improved by switching at the instant of passage of the negative half-cycle of oscillation through the energy recovery diode (D). To reduce the sensitivity to tolerances a clamping circuit (2) is added which limits the voltage (UT) across the semiconductor switch to a little less than the max. allowable value. A comparator (K) works with a temp.-stabilised reference voltage (Uref) and acts directly on the gate electrode of the transistor.
