Title: Method for detecting pinholes in continuously cast billets
Inventor: BJORNESTOL KARL O
IPC: G01N21/894
Filed: 1992-11-20
Abstract: ABSTRACT     The present application relates to a method for detection of pinholes in continuously cast metal billets wherein the continuously cast metal billets are continuously passed by a symmetric light source comprising a plurality of single light sources arranged in a circle or in another way such that the light falls substantially symmetrical on the part of the surface of the metal billet which is to be detected, in such a way that the surface of the metal billet which faces the light source is illuminated except for pinholes, reflected light from the surface of the billet is detected by means of a linescan camera arranged centrally in relation to the light source, which camera has a scanning direction normal to the direction of movement of the metal billet, whereby pinholes are detected by registration of reflected light intensity below a preset treshold value.

Inventor: BOUSQUET JEAN-CLAUDE
IPC: F41G3/26
Filed: 1992-12-10
Abstract: For training persons having to fire missiles from the shoulder, a simulator is proposed which comprises a simulated launch or firing tube (10), which carries a front, releasable or jettisonable mass (12) and a rear releasable or jettisonable mass (14) at its ends. These masses are held by electromagnets (34, 36j. When the person filing or finer presses tine trigger (18), the rear mass (14) is ejected to the left followed, with a time lag (.DELTA.t), by the front mass (12). Thus, the load relief and site and bearing movements felt by the finer during a real launch are restored.

Title: Magnetic bearing and method of adjusting the magnetic bearing
Inventor: BARDAS THEODOR
IPC: F16C39/06
Filed: 1993-05-10
Abstract: ABSTRACT OF THE DISCLOSURE           An  improvement  in  an active  bearing electromagnet having a ferromagnetic rotating part called  rotor  and  a  stationary  ferromagnetic body called  stator  having  power  windings  powered  by electrical currents from a power amplifier. A sensor winding on the stator provides a voltage to a low pass and high pass filter. A reference inductor external to the magnetic bearing also includes a power winding and sensor winding.  Voltage  induced  in  the  reference winding is rectified and compared with the filtered and rectified voltage  from the  sensor winding to produce a representation of a dimension of the air gap of the magnet.  A further improvement provides the velocity and force across the air gap in the magnetic bearing. A compensation circuit is supplied that establishes the magnetomotive force of the bearing electromagnetic path. The low frequency component of the compensating current and the induced voltage in the bearing electromagnet may be used to calculate the velocity of the rotor displacement and the force of the displacement.

Title: Image enhancement apparatus using variable light and variable integration time per pixel
Inventor: TULI RAJA S
IPC: H04N1/40
Filed: 1993-07-27
Abstract: IMAGE ENHANCEMENT APPARATUS USING VARIABLE    LIGHT AND VARIABLE INTEGRATION TIME PER PIXEL.            ABSTRACT          An apparatus which adjusts the sensitivity capability of a sensor pixel when the light input goes beyond its normal dynamic light range. The apparatus may use an adjustable strobe width and/or other methods to desensitize or sensitize the pixel when the signal is too high or too low respectively. The apparatus may also use a method by which incident light on the image is made to change instead of the strobe width. This invention also allows any non-linear output from any type scanner to be linearized. It allows subtle shades of grey, not normally viewed due to the "washing out" effects of very wide dynamic and intense input signals, to be displayed with greater clarity.

Filed: 1992-03-19
Abstract: 2106579 9216974 PCTABS00016 A novel method of producing weak-link grain boundary Josephson junctions in high temperature superconducting thin films is disclosed. These junctions are reliably and reproducibly formed on uniform planar substrates (10) by the action of a seed layer (40) placed intermediate the substrate (10) and the superconductor film (20). The superconductor film (22) grown atop the seed (42) is misoriented from the rest of the film (24) by an angle between 5· and 90·. The grain boundary (30) so formed acts as a high quality weak-link junction for superconductor devices. The performance of these junctions can be improved by the addition of buffer layers (50, 60) between the substrate (10) and the superconductor film (20).

Abstract: L'invention vise une poudre d'un alliage de Ni avec un autre métal choisi dans le groupe constitué par Mg La, Be et Li laquelle se présente sous laforme d'agglomérats de cristallites de taille inférieure à 100 nm et dont la structure cristalline permet une absorption d'hydrogène. La poudre en question qui est de préférence obtenue par broyage mécanique peut être constituée de cristallites deLaNi5 ou de cristallites d'alliages à base de Ni et de Be ou de Li ayant une taille inférieure à 100 nm. Préférablement, cette poudre est constituée de cristallites de formule Mg2-xNi1+x (x étant compris entre -0,3 et +0,3), ces cristallites ayant une taille inférieure à 100 nm et de préférence inférieure à 30 nm. L'invention vise également l'usage de cette poudre nanocristalline pour le stockage et/ou le transport de l'hydrogène. Il a en effet été découvert que ces poudres nanocristallines à base de nickel ne requiert aucun sinon un simple traitement d'activation à basse température. Il a également été découvert que la cinétique d'absorption et de diffusion de l'hydrogène est beaucoup plus rapide. Ceci peut notamment s'expliquer par le fait que la poudre nanocristalline possède une très grande quantité de joints de gain.

IPC: G01V1/137
Filed: 1993-07-01
Abstract: A seismic energy source (10) for producing pressure pulses is disclosed. The source contains a substantially symmetrical main chamber (22) for storing compressed fluid. Two shuttles (24, 26) adapted to abut against each other are slideably placed around the housing (20) to sealingly enclose the chamber (22). A separate control chamber (46) for each shuttle is formed to urge its associated shuttle against the other shuttle when pressurized fluid is supplied to the control chamber (46). A separate firing chamber (80) is formed for each shuttle between the shuttle and the housing.  The firing chambers are activated by the fluid from the main chamber (22) to simultaneously move both the shuttles (24, 26) away from each other to allow the compressed fluid to discharge from the main chamber (22) into the surrounding medium. A separate relief valve (81) is connected between each control chamber and the main chamber which allows the fluid from the control chamber to discharge into the main chamber when the control chamber pressure exceeds the main chamber pressure by a predetermined value.
