Patent DE-4119749-A1 (DE)
Inventor: SCHAAL WALTER
IPC: A01D45/06
Filed: 1991-06-15
Abstract: Described is a method of decorticating flax, and a machine suitable for doing this. The aim of the invention is to produce, after only a short dew-retting time or light chemical pre-treatment, a degree of decortication sufficient to form the preliminary step of a constant-flow fibre-digestion process. The flax is picked up as a tangled mass and processed in a tangential-flow breaker unit (10, 11) and a subsequent longitudinal-flow fibre scutching and cleaning unit (12). Incorporated in the first breaker (10) is a system of parallel slots and in the second breaker (11) a peripheral gap whose axis of curvature is at right angles to the slots in the first breaker (10). The fibre scutching and cleaning unit (12) has several longitudinal sections fitted with fibre-conveying and loosening means which separate and clean the fibres. The decorticated fibres are then compressed, in a built-on baler unit (22), into bales.

Title: Running yarn draw tension monitoring - uses different mean values together with measured value to identify types of faults
Inventor: DETERS LUDGER AUGUST DR
IPC: G01N33/36
Filed: 1991-06-15
Abstract: The monitoring system, to check the draw tension on a moving yarn esp. between the false twister and the outlet rollers in the texturising zone, forms a number of different means values over the length of the evaluation time. The relative position of the measured value to one or more of the mean values is used to develop a quality signal and/or the relative position of the mean values are determined among each other. Pref. the measured value is evaluated with the mean value which gives the shortest evaluation time. The relative position of pairs of means values uses those with neighbouring evaluation times. The relative position of one or more mean values, in addition, is assessed within a tolerance spread with the limits for each mean value. The tolerance spread gives a fixed positive and negative drift from a gp. mean value of those with an identical evaluation time. The measured values give a gp. of workstations or the mean values with matched evaluation times form a gp. of workstations. ADVANTAGE - The technique not only gives an absolute picture of the wound bobbin quality, but also gives the type of faults which affect the quality rating.

Title: Safety circuit for medical laser scalpel - detects parameters of test oscillation applied to all circuit components e.g. relay shutter, and power supply cut=off switch
Inventor: KOLLER ROMAN
IPC: B23K26/42
Filed: 1991-08-19
Abstract: The circuit initiates the self testing of the laser system, and switches off a faulty component when failure is detected.

Title: Parking brake with safety device for motor vehicle - is applied pneumatically by driver switch operation, inhibited in motion and while ignition is switched on
Inventor: SCHAEFER GUENTER
IPC: B60T17/18
Filed: 1991-09-05
Abstract: The pneumatic actuator (S) of the brake (B) is pressurised from a reservoir (D) and pump (P) when an electromagnetic valve (VD) is opened by an electric switch (ST) with inputs from a double safety device (S1,S2) and AND-gated signals from brake light and release switches (BL,LS).

Abstract: 2.1. The objective is to provide a process and an apparatus for the continuous production of mineral wool mats, by means of which a stable flow pattern is created in the chute, thus facilitating a clearly defined, homogeneous layer of deposited mineral wool. 2.2. According to the invention, at least one backflow region (24, 25) is generated in the chute (9) outside the fiber flow (23), which backflow region (24, 25) is sufficient for such a large-volume backflow with such a low mean velocity that appreciable upward fiber transport is avoided. In this connection, a portion (32) of the process air entrained with the fiber flow is deflected upward in the backflow, and another portion (34) of the process air is extracted. 2.3. Production of mineral wool. <IMAGE>

Title: Pallet transport system
Inventor: TENNER GUENTER DIPL ING
IPC: B65G47/26
Filed: 1993-01-22
Abstract: The invention relates to a pallet transport system with a roller table composed of a plurality of roller-table portions (1 to 4), each with its own drive, a first monitoring switch (14) being arranged at the start of a first roller-table portion (2) and a second monitoring switch (15) being arranged between the first and a second roller-table portion (2, 3), and the monitoring switches being actuable by a pallet (10 to 13). A first end-of-travel switch (17) within the first roller-table portion and a second end-of-travel switch (18) within the second roller-table portion are provided, the end-of-travel switches being actuable by a pallet. The distances between the first monitoring switch (14) and the first end-of-travel switch (17) as well as between the second monitoring switch (15) and the second end-of-travel switch (18) correspond, in each case, to a predeterminable minimum distance (x) between two adjacent pallets. The warning signals of the monitoring switches and end-of-travel switches are interlinked in such a way that the falling short of the minimum distance is recognised from them. The travel command (F8V, F7R) for the drive (5, 6, 7, 8) of the roller-table portion (2, 3) at the rear in the direction of movement of the pallets is interrupted until the minimum distance (x) between two adjacent pallets is obtained. <IMAGE>

Title: Single-track vehicles which do not tip over because of the stable equilibrium
Inventor: KLEMM WOLF
IPC: B62K11/00
Filed: 1993-04-13
Abstract: The invention relates to single-track vehicles which automatically stay in an upright position both when in a standing position and also during travel and are therefore suitable to be equipped with driver's cabs which protect their occupants in just the same manner as is expected from modern, multi-track cars. The single-track vehicles according to the invention require neither mechanical mechanisms nor mechanisms which are based on a gyroscopic effect for keeping their position upright, rather they maintain this position merely with the stable equilibrium. On account of their single-track arrangement, small vehicle width and other small dimensions, on the one hand, and their driver's cab and the driving comfort associated threwith, on the other hand, they are therefore adequate all-purpose vehicles and are in particular outstandingly suitable for town traffic.

Title: Method and device for the digital determination and remote interrogation of filling levels and levels in liquids or media of limited high viscosity, using discrete sensor positions
IPC: G01F23/30
Filed: 1993-04-24
Abstract: Methods and devices are used for the detection and remote interrogation of filling levels and levels, whereby in contrast with the prior art used, with almost exclusive utilisation of analogue (continuous) sampling, the procedure here uses digital methods, with closely-spaced discrete sensor positions, so that the errors associated with analogue methods are eliminated. For Claims 1 to 3, an electrical conductivity is presupposed in the case of the media. Main Claim 1 covers in general the detection of the liquid level by causing a potential state on pick-up contacts, while Subclaim 2 makes use of control as a function of the liquid conductivity. Main Claim 3 describes bringing about a defined sensor state as a function of the liquid level by means of an electrical displacement current between capacitor plates. The following claims from 4 onwards relate to (active or passive) sensor-controlling elements which are coupled (in a floating manner) to the upper limit of the liquid or of a more highly viscous medium and influence pick-ups adjoining it. In so doing, various physical principles are used which are assigned in each case to the individual claims.
