Patent EP-0273234-A2 (EP)
Inventor: MITSCHKE HELMUT
IPC: H04L25/48
Filed: 1987-12-04
Abstract: The system comprises a data bit source (1) with a single bus line (3) connected to its data output (2). A data bit series comprises a start bit and a specific number of data bits. The start bit has a trailing edge, the data bits a leading edge. The bit value of a data bit is characterised by the length of the pulse with which the data bit begins. An instruction decoder (4) samples every bit with a sampling pulse of a clock pulse counter (10) generated at a specific counter reading (z8), this counter being incremented by the pulses from a clock pulse source (11) and controlled by an edge detector (12). The data bit values which are written into a data bit memory (18) at the sampling times are converted at the end of the data bit series in an instruction memory (20) into control signals (S7) corresponding to the stored instruction. The clock pulse frequency of the clock pulse source (11) does not need to be precisely defined. <IMAGE>

Inventor: LEVACHER FRIEDRICH KARL DR
IPC: G01J3/28
Filed: 1989-01-07
Abstract: A device is known for measuring the concentration of explosive gases in air, comprising a measuring chamber with a gas sensor (GS), an optical waveguide (LWL) connection cable (LK) and a measuring device (MG). In the sensor, a light beam is divided into two beams, where one beam is passed through the gas mixture, the other through a reference gas and both beams are recombined. In this process, an interference grating dependent solely on the extraneous gas concentration (density) is formed and this grating is superimposed on a predefined phase grating. This produces a Moiré effect, the structure of which is optically recorded and electronically evaluated. This device and the method are to be redesigned to produce a gas concentration monitor for an enclosed high-pressure gas container, where the latter has a smaller measuring chamber. The object is essentially achieved by disposing the following components as a gas sensor (GS) in the longitudinal axis of the measuring chamber: two optical waveguide connections emerging from the connection sockets (3), the end surfaces (4) of which are located at the focal point of a convex lens (5), the lens itself, a flat glass panel (6) at a distance from and parallel to the lens and with a semi- transparent, semi-reflective back surface and also a further glass panel (7), in this case with a reflective front surface. The device serves primarily as a gas concentration monitor for high-pressure gas-insulated switching units. <IMAGE>

Abstract: A recording medium for electrothermal transfer printing comprising a base film, an adhesiveness improving layer provided on one surface of the base film, an electrically resistive layer provided on the adhesiveness improving layer, and a heat-sensitive transfer ink layer provided on the other surface of the base film, said electrically resistive layer comprising a binder comprising a polyvinyl butyral resin as a main component, an electrically conductive powder and an inorganic metallic compound type flame retardant. The content of an electrically conductive powder such as a conductive carbon in the resistive layer can be increased to reduce the electric resistance of the resistive layer and problems such as peeling of the resistive layer can be prevented, and a satisfactory flame resistance can be obtained without increasing the resistivity of the resistive layer. Thus, the electrothermal transfer printing can be conducted safisfactorily without any dangerousness.

Abstract: A numerical control apparatus for machining non-circular workpieces such as a cam and the like has been disclosed. The cam and the like are used in changing the operation from rotational to linear motion. In designing the shape of the cam and the like, lift data prescribing the relationship between the rotational and linear motions is used. The lift data is given by the position sequence on the linear motion corresponding to a number of discrete rotational angles. Also, the tolerance of the positions is given from a functional aspect. The lift data is converted into profile data prescribing the shape of the cam and the like after being smoothed within the tolerance by a regression analysis, and machining of the non-circular workpieces is effected according to the profile data.

Abstract: Flow pulsing apparatus is adapted to be connected in a drill string above a drill bit. The apparatus includes a housing providing a passage for a flow of drilling fluid toward the bit. A valve which oscillates in the axial direction of the drill string periodically restricts the flow through the passage to create pulsations in the flow and a cyclical water hammer effect thereby to vibrate the housing and the drill bit during use. Drill bit induced longitudinal vibrations in the drill string can be used to generate the oscillation of the valve along the axis of the drill string to effect the periodic restriction of the flow or, in another form of the invention, a special valve and spring arrangement is used to help produce the desired oscillating action and the desired flow pulsing action.
