Title: Two-position solenoid valve
Inventor: STEGMAIER ALWIN
IPC: F16K31/06
Filed: 1985-09-28
Abstract: The invention relates to a compact two-position solenoid valve which is, in particular, designed as a multiple compound solenoid valve for carrying out ABS functions comprising holding functions in vehicles. According to the invention, the following components are arranged in the stepped bore of a one-piece block housing: the magnet coil towards the outside, adjoining the latter a non-magnetic separation (air gap), simultaneously designed as an annular guide bush for the armature, and, towards the bottom, the valve formed by a sealing ball and a seat sleeve. In this arrangement, a projection of reduced diameter on the armature projects into a bore in the cap which closes the housing bore, with the result that the magnetic circuit is formed by the housing, the cap, the armature and, if required, the holder for the sealing ball. The cap and the housing at the same time centre the guide bush. The block housing preferably consists of sectional steel material of a suitable shape, in the form, for example, of U-, E- or I-section steel and provides compact accommodation for two or even four solenoid valves, in each case with a common connection to the master brake cylinder. <IMAGE>

Title: Circuit arrangement for starting and operating a fluorescent lamp
Inventor: VAY ROLAND DIPL ING
IPC: H05B41/36
Filed: 1985-10-11
Abstract: In order to start a fluorescent lamp (3) which is connected in series with an upstream inductor coil (choke) (5, 5'), an electronic starter is in widespread use which connects a capacitor in series with the inductor coil and in parallel with the fluorescent lamp. The high-frequency oscillations produced by the LC series tuned circuit cause the lamp to start. In addition, a reactive volt-ampere compensation capacitor is required in order to operate the lamp. In order to be able to use a single capacitor (9) both for starting and for reactive volt-ampere compensation, an electronic starter (8) is proposed which has a changeover device (26) which connects the capacitor (9) in series with the inductor coil (5, 5') for starting the fluorescent lamp (3) and in parallel with the mains power supply connecting terminals (N, P) for operation of the lamp. The changeover device (26) is driven by means of a voltage comparator (23) having hysteresis, as a function of the lamp voltage which is present at the point where the inductor coil is connected to the fluroescent lamp. <IMAGE>

Patent DE-3542311-A1 (DE)
Title: Apparatus for generating approximate weightlessness for sensitive production processes on earth
Inventor: LORENZ ALBERT DR
IPC: B01J19/00
Filed: 1985-11-29
Abstract: Weightlessness over prolonged periods is only available in space. The cost and effort involved in this limits the often interesting applications to processes having a very high added value. Under terrestrial conditions, it can be approximated over an unlimited period if the reaction chamber is subjected to a cyclic falling motion and slowly rotates by 180 DEG  during each cycle. As a result, the shock effect causing problems at the lower return point is neutralised. Subject to certain restrictions, processes taking a long time can proceed under conditions of g = l, which would otherwise require weightlessness.

Patent DE-3546448-A1 (DE)
Title: Bending apparatus
IPC: B21D7/022
Filed: 1985-03-12
Abstract: The invention relates to a bending apparatus for rod- or strip-shaped material, having a bending station, arranged in a working plane, for at least one bending core, which is fixed above the working plane during bending, and at least one body of revolution, which carries at least one bending figure rotatable about the bending core and displaceable perpendicularly to the working plane. In a known bending apparatus, it is virtually impossible to vary the bend or change the mode of bending without retooling the bending station, and this is time-consuming. In fact, this may be necessary several times with one and the same work piece. According to the invention, it is proposed that the body of revolution be surrounded on the outside by a concentrically and rotatably mounted annular body with at least one further bending finger axially displaceable by way of the annular body. By virtue of its better flexibility, the bending apparatus can be adjusted rapidly even while in the process of working on a work piece.

Title: Method for contactless determination of the spatial position of an object point located on the surface of a body
Inventor: JUNG ARTUR PROF DIPL ING
IPC: G01B11/00
Filed: 1986-12-20
Abstract: A method for determining the spatial position of an object point located on the surface of a body with the aid of opto-electronic means containing imaging optics and a light source. A contactless uniaxial displacement measuring system is known which determines, with the aid of a diffuse-light curtain into which a diaphragm or an object emerges, the position of this element in this area. The optically turbid layer in this arrangement is only used for compensating for the differences in the transmitting and receiving chips used. It is the object of the invention to provide for the direct uniaxial, biaxial or triaxial measurement of the coordinates of points on an object surface by contactless means with the aid of an optically turbid layer without shading problems. The object point is imaged into the optically turbid medium and the imaged point is detected by means of photosensitive elements via the variation of the scattering and transmission characteristic of the light propagation in the turbid medium. The output signals for these elements are then supplied to an evaluating circuit which renders the spatial position of the object point recognisable. The uniaxial, biaxial or triaxial measurement of the coordinates of points on an object surface without optical quality.
