Patent DE-3230397-A1 (DE)
Title: Flow metering device based on the ultrasound principle with two oscillators
Inventor: NAKAGAWA YUKIO DIPL ING
IPC: G01F1/66
Filed: 1982-08-11
Abstract: A flow metering device contains two ultrasound transducers (41, 43) in each case operating as a transmitter or receiver to which the frequency of one or the other oscillator (13, 15) can be supplied as desired by means of changeover devices (24, 45) when the direction of the ultrasound propagation changes. A counting circuit (61) emits an end-of-count signal (63) corresponding to the frequencies of the oscillators (13, 15) when a pre-defined counter reading is reached, while a control device (59) influences the frequency of the oscillators (13, 15) to the effect that a predefined relationship between the propagation time of the ultrasound waves (45, 47) and the counting time of the counting circuit (61) is maintained until the predefined counter reading is reached. To compensate for the effect of temperature changes, a device (81, 85) is provided to change the number N which is set in the counting circuit (61) according to the sum of the frequencies of the two oscillators (13, 15) in order to cause the latter to converge in a predefined range. <IMAGE>

Patent DE-3238821-A1 (DE)
Title: Ink jet printer
Inventor: EBI YUTAKA
IPC: B41J2/06
Filed: 1982-10-20
Abstract: In a commodity ink jet printer, which prints out data in various forms, such as characters or numbers, by the linkage of dots, which are formed by ink droplets, on a sheet of paper, an ink ejection head has control electrodes which are arranged at least in one ink passage. Ink droplets are formed and fly through electric fields which have been developed in the vicinity of the control electrodes when voltages are applied. An ejection of ink over a multiplicity of openings is achieved by providing a multiplicity of ink passages in the head. The voltage supply of the control electrodes can be controlled in such a way that ink droplets are formed and execute a flight corresponding to printing signals. A groove or channel which defines each ink passage can be formed readily and accurately in that an etching characteristic is utilised, in particular in a specific crystal surface. A multiplicity of acceleration electrodes can be used in order to encourage desired flight paths of ink droplets. Furthermore, a counter-electrode can be arranged in the head opposite the control electrodes so that the ink droplets are formed and fly in an even more effective and reliable manner.

Title: Aggregation-preventing indwelling cannulas or catheters
IPC: A61M25/00
Filed: 1982-11-05
Abstract: Indwelling cannulas or catheters for administration of medicines, solutions, hormones or the like into the human body tend to cause platelet aggregation, fibrin deposits and thrombi which necessitate removal of the cannulas. This is to be avoided by the fact that a low-frequency alternating electrical potential is set up in and around the cannula.

Patent DE-3310866-A1 (DE)
Title: Solenoid valve with a plurality of operating positions
IPC: H01F7/14
Filed: 1983-03-25
Abstract: A multi-position solenoid valve is described which has a plurality of electromagnets (10, 12, 14 and 11, 13, 15) and a restoring spring (8). A stop (10 or 11) is allocated to each electromagnet (10, 12, 14 or 11, 13, 15). When the stop (10 or 11) is reached, the individual electromagnet (10, 12, 14 or 11, 13, 15) no longer contributes to the further displacement of the displaceable part (9) of the valve. These stops (10 and 11) also determine the operating positions. The individual electromagnets (10, 12, 14 and 11, 13, 15) are now designed in such a way and their energising current is proportioned in such a way that each electromagnet ensures that the movable part (9) is displaced from the preceding position into the operating position determined by its stop. <IMAGE>

Title: Control of a press
Inventor: HUYDTS EDUARD J C DIPL ING
IPC: B30B15/16
Filed: 1983-05-19
Abstract: Control for a hydraulically driven press having a plurality of power cylinder piston arrangements, which, during the power stroke, act on the press tappet with an increasing operating pressure and which, at the same time, are equipped for the return stroke, and having at least one controllable-delivery pump and a flywheel, which is rigidly attached to the pump shaft and which stores all or at least most of the energy required for a working cycle of the press. An additional controllable-delivery pump is provided, which is driven by an electric motor without a flywheel. This additional pump, prior to the working cycle of the press, and for the purpose of starting or charging the flywheel, can be connected on its discharge side to the suction side of the first mentioned pump, which as a result acts as a motor, effectively driving the otherwise driveless flywheel. <IMAGE>

Title: Method and device for measuring surface defects on metals
Inventor: HIROSHIMA TATSUO
IPC: G01N27/82
Filed: 1983-06-14
Abstract: A method and a device for measuring surface defects on metals is capable, according to the invention, of simultaneously detecting all the defects regardless of whether they are open or not open to the surface or are pit defects and of detecting the defects regardless of their direction of propagation. At the same time, the defects can be differentiated in terms of their properties. For this purpose, a magnetic field detector measures a resultant magnetic field formed by magnetic fields extending along, and perpendicular to, the surface of a specimen (11). The resultant magnetic field is composed of the stray magnetic field which is due to surface defects and is produced by the component of the resultant magnetic field along the surface of the specimen (11), and of the magnetic field which is due to an eddy current and which is produced on the surface of the specimen (11) by the component perpendicular to the surface. <IMAGE>

Title: Device for sealing off bearings, in particular encapsulated maintenance-free bearings
Inventor: LORENZ GERHARD
IPC: F16C33/74
Filed: 1984-04-04
Abstract: The invention relates to a device for sealing off bearings, in particular encapsulated maintenance-free bearings. The device has an exchangeable seal which prevents the penetration of foreign bodies between the sliding faces of the parts of the bearing which move relative to one another. On one side, the seal is provided with sealing lips and, on the rear side, is profiled. It is seated in a recess in the bearing, which recess is designed with complementary profiling to the profile of the rear side of the seal. On the side opposite the sealing lips, the seal has a groove, ribs thus being formed on both sides of this groove. A web formed in the recess of the bearing engages in the groove and the ribs of the seal are seated in grooves of the sliding bearing. The sealing device is simple and cheap to manufacture. The seal is equally suitable for radial and thrust bearings. The seal can be inserted and exchanged rapidly and in a simple manner by hand without a tool. For producing the profiled recess in sliding bearings, use is made of a special blanking plate which can be inserted exchangeably in a locating device which can be mounted in any suitable machine tool. <IMAGE>
