Title: Method for the production of washers, in particular for high-strength bolt connections
Inventor: ESCHER OTTOKAR
IPC: B21D28/06
Filed: 1983-03-07
Abstract: The invention relates to a high-strength washer and to a method for its production and can be employed together with a high-strength bolt connection in almost all areas of technology. The aim of the invention is to create a washer of high strength with the use of less material with a view to light weight, with an increased degree of utilisation of the material and with less outlay on production. At the same time, the intention is to improve the performance of high-strength bolt connections. The solution consists in a geometrical optimisation of the final diameter of certain nominal sizes of washer, making possible multiple arrangement one inside the other and in the interspaces, and a production method. The starting material, e.g. strip steel, is here matched to the strength of high-strength bolts. The largest washer, which is taken as a basis for a cutting-pattern combination and which determines the thickness of the starting material, is only about 5% of the thickness of the conventional washer of the same dimensions. <IMAGE>

Patent DE-3312722-A1 (DE)
Title: NC EDM process and apparatus
Inventor: INOUE KIYOSHI
IPC: B23H7/28
Filed: 1983-04-08
Abstract: An NC EDM process and apparatus, where a sequence of electrical discharges is performed in an EDM working gap for the electroerosive removal of material from the workpiece, while the tool electrode is fed relatively in succession into the workpiece under NC commands which in a predetermined set establish a desired path and a desired size of the relative feed. The EDM current supply (generator) is controlled in such a way that the parameters of the electrical discharges are held in a predetermined EDM mode of operation during an initial period of the successive feed of the tool electrode relative to the workpiece. The occupying of a position of the tool electrode relative to the workpiece, at a predetermined distance from its final position, which is determined by the size of the successive relative feed, is detected for changing over the parameters of the electrical discharges into another EDM mode of operation and for maintaining the changed-over parameters until the tool electrode occupies the end position relative to the workpiece.

Title: System for determining the location of a vehicle
Inventor: HAUSER FRANZ
IPC: G01C21/00
Filed: 1983-04-25
Abstract: The present invention is based on a system which consists of a continuously operating transmitter and a receiver with a direction finding antenna or directional antenna. Using this known system, the location of the transmitter, which is mounted on a vehicle, could only be determined in a cumbersome and inaccurate manner by finding the direction at least twice by means of a directional antenna of the receiver from two different locations. The transmitter of the system according to the invention has a measuring unit which responds to a movement of the vehicle and a navigation computer which determines data on a distance travelled by the vehicle from the output signals of the measuring unit and sends out these data. This signal is evaluated at the receiver end and displayed. The data displayed enable the site of the transmitter to be determined in a simple manner.

Patent DE-3330099-A1 (DE)
Title: Quasi-planar structure for the integration of transistors into waveguide circuits
Inventor: EBNER HERMANN DIPL ING
IPC: H01P5/08
Filed: 1983-08-20
Abstract: The invention contains a planar line structure which is applied onto a thin dielectric substrate 1 and is installed in the centre plane of a rectangular waveguide. It comprises a modified waveguide-stripline transition in which the metallisations 4 and 5 for the power supply, and 13 for resonance suppression in the waveguide frequency band, are integrated. The transistors are inserted in the stripline region 3. The transition forms a non-homogeneous, antipodal fin line which has a slot region 2 with a dissipative coating. In consequence, a reflection attenuation at low frequencies which is necessary for oscillation-free operation of microwave transistors is achieved, without significantly influencing the transmission and reflection properties in the waveguide band. The additional metallisations 7 and 8 together with the dissipative slot region determine the reflection attenuation below the waveguide limiting frequency. The contours and the lengths of the non-homogeneous line regions 9 to 12 define the reflection and transmission properties in the waveguide band. A photolithographic production method ensures excellent reproducibility of the radio-frequency electrical structural characteristic parameters. The fields of application are in precision microwave metrology and in the construction of (broadband) amplifiers for the microwave band. <IMAGE>

Title: Magnetic clothing
Inventor: STRAHL GERHARD
IPC: A61N2/08
Filed: 1983-08-31
Abstract: One-piece suit with a hood covering the entire human body with the exception of the eyes, the nose and the mouth. The suit with a hood is woven from elastic, magnetisable fibres. The magnetic orientation and magnetisation takes place via an electrical high-voltage process.   The scientifically proven promotion of, for example, the blood flow through the human skin and the extremities by magnetic forces can be best achieved with an elastic suit with a hood which is accurately adapted to the person's height, because such a suit with a hood, or partial clothing made of a magnetic woven material, can be worn close to the body without impeding the wearer (direct exposure of the skin to the magnetic forces), that is to say, can even be worn inconspicuously during the day under normal clothing.

Title: Apparatus for the process for improving the scrubbing out of SO2 downstream of fossil fuel power stations in the limestone process
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/50
Filed: 1983-09-23
Abstract: The main application P 3332894.3 relates to a process for scrubbing acid flue gases, preferably downstream of fossil-fuelled boilers, according to which the base water is produced from a limestone and, depending on the degree of scrubbing out of, for example, greater than 90%, with alkali metal hydroxides or alkaline earth metal hydroxides, such as, for example, lime hydrate or carbide slurry, is additionally admixed to the base suspension. In order to optimise this process, it is proposed according to the invention that the first contacting scrubbing (2) with the untreated gas is designed as a limestone suspension scrubbing using a jet, where the scrubbing can be designed as parallel flow or counter-current scrubbing and in the second contact plane (3) is carried out by lime hydrate suspension. In the second contact plane (3), the scrubbing can alternatively be carried out by limestone plus lime hydrate suspension. <IMAGE>
Patent DE-3336231-A1 (DE)
Inventor: ACHELPOHL FRITZ
IPC: B26D1/12
Filed: 1983-10-05
Abstract: In an apparatus for making plastics carrier bags from a web of tubular film of thermoplastic material, a feeding mechanism intermittently conveys the webs by one bag width and a severing mechanism cuts the web into half tubes along an undulating curve. A carriage displaceable in the machine frame transversely to the feeding direction of the web is reciprocated by a drive derived from a first rotating control cam through gearing. A cutting knife pivotable in the carriage about its longitudinal axis passes through the plane of the tube about an axis perpendicular thereto and is so controlled by an oscillating drive derived from a second rotating control cam that its edge is substantially tangential to the undulating curve at the cutting point. A detour assembly retards one of the half tubes to bring the bag side edge zones into phase and each half tube is formed into bags by a transverse sever-sealing device.

Abstract: The container transport system (20) has a crane girder (21) which can be moved on running rails (23) on both sides of a crane zone. A travelling crab (25) can be moved on the crane girder (21). The travelling crab (25) has a lifting mechanism (27) with a primary load-carrying means (31) for containers (34). In addition, a transfer device (40) is arranged on the travelling crab (25). The transfer device (40) has a secondary load-carrying means (41) for containers (34). This secondary load-carrying means (41) can be moved in the horizontal direction into at least two positions. One position is perpendicularly below the the primary load-carrying means (31) for the purpose of transferring one container (34) from one to the other load-carrying means. The other position is above a fixed transfer station (35) which is arranged outside the range of movement of the primary load-carrying means (31), generally outside the crane zone, and is equipped with a rigid load-carrying means (36) for containers (34). The secondary load-carrying means (41) can be formed by a telescopic device (44). The transfer device can also be arranged between the travelling crab and the primary load-carrying means, and the latter can then at the same time be used as the load-carrying means of the transfer device. <IMAGE>

Title: Method for replacing shut-off devices from pipelines of transformers
Inventor: BIRNER FRIEDRICH DIPL ING
IPC: F16L55/132
Filed: 1984-04-12
Abstract: In the case of repair and servicing tasks on cooling systems of large transformers, from time to time it is necessary to replace shut-off devices (2, 3) from their pipelines (1). In the past, before removal of the shut-off devices, it was necessary to drain all the fluid coolant, and to prepare it again in a time-consuming and costly process, before reuse. According to the invention, it is proposed to mount a cap (4) containing a plug on the side of the shut-off device facing away from the transformer, the plug of which cap (4) is pushed through the shut-off device (2, 3) once the latter has been opened, into the connected pipeline end (1) and is anchored there while at the same time sealing the pipe, so that, thereafter, it is possible to replace the shut-off device without draining the coolant out of the transformer. <IMAGE>

Title: Process for transporting and heating a polyolefin film and device for carrying out the process
Inventor: KIEFER GUENTHER
IPC: B29C51/26
Filed: 1984-09-06
Abstract: The invention relates to a process for transporting and heating a polyolefin film before it is thermoformed by differential pressure and a device for carrying out the process. In order to compensate for the longitudinal expansion of the film web during heating without special chains and without linear longitudinal support in the heating region, it is proposed to allow at least two circulating transport chains with gripper devices to act at each lateral edge of the film web, the second transport chain having a somewhat higher transport rate. The transfer point lies below the heater, so that at the transfer point a stretching of the film web in the longitudinal direction and thus a compensation of the previous longitudinal extension takes place. This prevents undulation of the film web. <IMAGE>

Title: Method for preventing misuse in telecommunications networks, in particular mobile radio networks
Inventor: DIEDERICH HANS G DIPL ING
IPC: H04W12/06
Filed: 1984-11-15
Abstract: To render misuse of subscriber devices more difficult through computer-aided checking of secret identifiers in cellular mobile radio networks, no special response on the part of the central station which can be detected by the misuser initially occurs in the event of an attempted misuse which can be detected by the central station as early as during the log-on procedure. The identifier of the subscriber device which has no access clearance is, however, stored in the central station. Only during one of the subsequent connection set-up attempts does the central station respond in a manner which can be detected by the subscriber device, either by not setting up the requested connection or by clearing the initially set-up connection after a specific time. In both cases, an announcement can be transmitted to the subscriber device instead of the requested connection being set up. Alternatively, the subscriber device without access clearance is disabled by the central station for at least a specific time. The subscriber device may either be irreversible, in which case a specific subscriber device component must be replaced, or this component can be re-enabled by means of a special device. Both options are available to the network operator (Fig. 5). <IMAGE>
