Abstract: ABSTRACT          The present invention relates to a brake arrangement in linear motion operating devices of the kind which comprise a cylinder (1), a piston which is movable in the cylinder, and a rail (3) which is mounted on the outside of the cylinder (1), parallel with the cylinder axis, and which extends substantially along the whole stroke path of the piston. The rail is configured with slide surfaces (8) on opposite sides thereof, and the arrangement further comprises a slide (14) which is configured with slide shoes (15) and which is guided for linear movement along the slide by the slide sur-faces (8), this slide being connected to a dogging element (2) connected to the piston. The arrangement is characterized in that the rail has formed therein at least one cavity (9) which extends along the rail (3) and which is open through the intermediary of a passageway (10), whereby the rail presents at least one leg (11) which is resilient in a direction transversely to the cylinder axis and which defines one side of the passageway, and which leg is intended to coact with a brake body (21) mounted on the slide (14) and having a brake surface (22). The cavity can be placed under pressure so as move this one side of the leg out of coaction with the brake surface.

Title: Process for producing a high-temperature superconductor
Inventor: BOCK JOACHIM
IPC: H01L39/24
Filed: 1991-04-02
Abstract: To produce a high-temperature superconductor of the composition Bi(2+a)(Sr(1-b)Ca b)(3-a)Cu(2+c)O(8+x), where a is from 0 to 0.3, b is from 0.1 to 0.9 and c is from 0 to 2, and x has a value which depends on the oxidation state of the metals contained, oxides and/or carbonates of bismuth, strontium, calcium and copper are thoroughly mixed. In this process, the copper compound is used as a mixture of copper(I) oxide and copper(II) oxide. Then the mixture of oxides and/or carbonates is first allowed to react mutually in an inert gas atmosphere at temperatures from 700 to 800°C for 0.5 to 36 hours before subsequently treating the mixture in an oxygen-containing atmosphere at temperatures from 700 to 875°C for 3 to 60 hours.

Abstract: Dkt. No. 35-OR-919 ABSTRACT OF THE DISCLOSURE             To override the vehicle immobillzing effect of a failed automatic ratio controller in a hydromechanical transmission, the conventional manually shiftable range selector is loosely linked with a ratio arm while the latter is being stroked by the controller to vary hydrostatic output speed. Upon controller failure, the range selector is drivingly linked with the ratio arm, such that shifting movements of the range selector are translated into stroking movements of the ratio arm to provide manual control of vehicle propulsion.  Safeguards are provided to ensure that conversion between the normal propulsion mode governed by the automatic ratio controller and the override propulsion mode manually governed by the vehicle operator is effected in a safe manner.

Title: Inductive flow meter
Inventor: KETELSEN BRODER
IPC: G05D7/06
Filed: 1991-01-22
Abstract: ABSTRACT OF THE DISCLOSURE         An inductive flow meter is used to measure the flow of electrically conductive liquids through an electrically isolating section of a flow channel, provided with diametrically opposed punctual elec-trodes and crossed in this area by a transversal magnetic field.  In order to reduce the influence of the path of the current concentration in the area next to the electrodes when the flow is unevenly distributed across the channel cross-section, which could falsify the measurement signal, magnetic return branches separated by gaps are arranged outside the flow channel.  The gaps are located, in relation to a cross-section, in areas next to the punctual elec-trodes at the periphery of the flow channel, so that the magnetic field lines of the magnetic return, that extend across the gaps, extend across the inside of the flow channel as well, in areas next to the electrodes or in marginal areas downstream and upstream of the latter.

Abstract: A balanced cascode current mirror includes a first and second current paths respectively defined by first and second transistors and by third and fourth transistors.  Each current path may include the sources and drains of the transistors in such path.  Connections may respectively extend between the gates of the first and third transistors and between the gates of the second and fourth transistors to provide the first and third transistors with substantially identical source, gate, and drain impedances.  An input current is introduced to the drain of the second transistor and an output current with substantially identical characteristics is obtained from the drain of the fourth transistor. A capacitance may be connected between the drain of the second transistor and the gate of the first transistor to produce a flow of a current at high frequencies through the first current path corresponding to the input current at the drain of the second transistor.  A fifth transistor may be connected in a circuit with a constant current source to regulate the current through the first and second transistors to be substantially equal to the input current at low frequencies.  The gate of the fifth transistor may be connected to the drain of the second transistor, and the source of the fifth transistor may be connected to the gate of the first transistor, to provide this current regulation.  The gates of the second and fourth transistors and the drain of the fifth transistor may have a common reference potential such as ground.

Abstract: A temperature monitoring unit that allows to improve temperature monitoring sensitivity of a rotary heating element and to monitor temperature of a larger heating element is provided.  The temperature monitoring unit is comprised of a mirror which is provided in the vicinity of a rotary heating element, reflects infrared rays generated from a thermal point on the heating element toward outside in the radial direction thereof and reciprocates linearly in the radial direction, a condenser lens provided outside of the heating element for condensing the infrared rays reflected by the mirror, an infrared sensor provided on the condenser section, a slit plate which is provided on the mirror side of the lens and which has an opening which is long in the direction approximately perpendicular to the surface of the heating element, and an image processor for inputting the output of the infrared sensor.  The sensitivity is improved because infrared rays from around the thermal point of the heating element is blocked by the slit plate.  Moreover, the visual field becomes long in the radial direction of the heating element, so that the moving speed of the mirror can be increased.
