Title: Torque restrictor - has cams sliding shaft or cylinder axially to radially separate adjoining circumferential faces and release friction coupling without loss of oil
Inventor: KAWASAKI TOSHINOBU
IPC: F16D7/02
Filed: 1993-06-15
Abstract: The conical outer circumferential face of the shaft (11) fits against the conical inner circumferential face of the cylinder (10).

Title: Sensor and transducer for magnetic field to light
Inventor: NEUSEL ROLF
IPC: G08C17/00
Filed: 1993-07-31
Abstract: A magnetic field to be detected affects the spatial disposition of a current path. The respective disposition of the current path affects the radiation of a light source. The light modulated by the magnetic field is fed out via optical waveguides for electrically decoupled further processing. The operating current is generated from integrated photocells within the sensor, the photocells being fed via optical waveguides or direct illumination. According to the invention, the feed light is coded in a known manner and interferometric and compensative methods are involved. The representation of the so-called reference light by means of a further light source integrated in the sensor and a further optical waveguide to feed out the reference light are provided. The use of pole shoes for field concentration onto the current path is provided for. The current path is provided not only in thin layers but also in a vacuum or plasma. With the known methods of integrated technology, economical manufacture taking up minimal space can be achieved, the effects of magnetic interference being simultaneously minimised.
Patent DE-4326448-A1 (DE)
Title: Valve, in particular directional control valve
Inventor: SCHNEIDER BRUNO
IPC: F16K11/07
Filed: 1993-08-06
Abstract: The invention is based on a valve, in particular a directional control valve, which has a valve housing, a piston bore constructed in the valve housing and connected to a pressure connection, a tank connection and at least one consumer connection, and a controlling piston which is movable to and fro in the piston bore and by which, via controlling-edge pairs constructed on it and also on the valve housing, the pressure-medium paths between the connections can be controlled. A controlling-edge pair is formed by an outer edge between the piston bore and an exterior of the valve housing and by an edge on a piston land of the controlling piston. In addition, the controlling piston possesses in front of its controlling edge a guide portion having at least one axial passage. In an earlier patent application, the guide portion is at a distance from the piston land. In order to simplify production of the controlling piston, provision is made in a valve according to the invention for the guide portion to adjoin the piston land directly. All that is then required is to turn an annular groove in the controlling piston on one side of the guide portion.

Title: Purification of spring- and well-water - before filtration raw water mixes with pressurised water contg. gas where resulting bubbles assist sepn. of impurities by flotation
Inventor: ICHIHARA HISASHI
IPC: B01D36/00
Filed: 1993-10-14
Abstract: New procedure for filtering spring water (W1), contg. solid impurities (SS) enters the upper part of a filter vessel (2) which contains a filtration material. The procedure consists of: (a) an inlet process in which the spring water and pressurised water (W4) having large quantity of gas dissolved are introduced into the upper part of the vessel in such a way that they mix with each other; (b) a flotation process in which most of the impurities adhere to the large number of gas bubbles released by the pressurised water and are carried upwards to the top of the vessel; and (c) a filtration process in which the water passes through a filtration material in the lower part of the vessel. USE/ADVANTAGE - For purifying spring or well water. The quantity of impurities deposited in the filtration material is greatly reduced. The rate of filtration can therefore be increased, the life of the filtration material is extended and back-washing of the filtration material is required less frequently. Water containing a high level of impurities can be successfully purified.

Patent DE-4407377-A1 (DE)
Title: Modified reaction chamber for rapid heating system
Inventor: NENYEI ZSOLT DR
IPC: C23C16/44
Filed: 1994-03-05
Abstract: Due to the cross-reduction of the reaction chamber only a narrow horizontal gap remains face as opening for the wafer handling. The cross-section restricting insert may be firmly coupled or welded to the chamber. The reduced opening permits wafer handling, but prevents air inflow into the chamber during the chamber door opening. The pre-rinsing of the chamber typically starts with a laminar flow due to the restriction.
Patent DE-4408765-A1 (DE)
Title: Engine control system
Inventor: KOBAYASHI HIDEKI
IPC: F02B33/00
Filed: 1994-03-15
Abstract: In an internal combustion engine with a supercharger, slipping of the driven wheel is controlled in that the engine torque is reduced when the extent of the wheel slip relative to the road surface becomes too great. If the engine running status lies in a non-supercharged range, the wheel slip is controlled by at least one of the processes in order to reduce the amount of fuel being fed to the engine and to retard the firing point (first slip control). If the running status lies in a supercharging range, however, the slip is controlled by reducing the supercharging pressure (second slip control). In a transitional period in which the running status of the engine is changed from the non-supercharged range into the supercharged range, and if the first slip control is performed in the non-supercharged range, the first slip control can be continued instead of the second slip control, until the wheel slip is made to converge.
