Title: Composite densification with benzoxazines.
Inventor: ISHIDA HATSUO
IPC: C07D265/16
Filed: 1992-03-10
Abstract: A method for forming carbon-carbon composites consists of impregnating structures with carbon-forming precursor compounds comprising multi-functional benzoxazine compounds. The impregnated structures are pyrolyzed to form carbonaceous char which serves to fill the interstices in the structure, thus densifying the composites. The process of impregnation and pyrolysis is repeated as many times as required to obtain the composite density desired. Unusually high char yields are produced by multi-functional benzoxazine compounds in which benzoxazine are joined to each other through a bridge characterized by having conjugated unsaturation associated therewith. A number of preferred compounds providing unexpectedly high yields of char are shown, enabling the desired densification to be achieved with a minimum number of impregnation and pyrolysis cycles, thereby reducing the costs of forming the composites.

Title: An adjustable pipe bend for drain pipes.
Inventor: OLSSON JAN
IPC: F16L27/08
Filed: 1992-05-07
Abstract: An adjustable pipe bend comprises two pipe bend parts (10, 12) having abutting end portions (14, 16) extending in a plane which is inclined, an angle  alpha  of 22.5 DEG  relative to a plane perpendicular to the main axis (18, 20) of the respective pipe bend part (10, 12). The pipe bend parts (10, 12) are rotatably connected to each other at said end portions (14, 16) for rotation about an axis perpendicular to said inclined plane by means of snap-lock connecting elements (22, 24) placed outside the light borings (26, 28) of said pipe bend parts (10, 12). Each connecting element is shaped as a body of rotation about said axis of rotation, and the snap-lock connection includes an O-ring seal (30). The pipe bend may optionally be set to any bending angle between 0 DEG  and 45 DEG  by turning the two pipe bend parts (10, 12) relative to each other, and in any position of the two pipe bend parts (10, 12), their main axis (18, 20) will either intersect each other or be substantially coincident.

Filed: 1993-03-04
Abstract: A power supply shunt regulator (PSSR) is proposed which regulates the current flowing to a branch (FET, L D , CSR) coupled in parallel to a power supply (SA) and an electrical load (EL). 
     The proposed regulator limits the discharge current from a parasitic capacitor (PSC) of the power supply when a shunt switch included in the branch is turned on. An active negative feedback loop (CLM, FET) therefore regulates the current through the branch by measuring the voltage drop (RI) over a current sensing resistor (CSR) included therein and by deriving a control signal (ACTRL) for the shunt switch in such a way that this voltage drop strives in a critically damped way to a maximum voltage drop. This can be done in a simple way, taking into account that the shunt switch is chosen to be a field effect transistor, thanks to the fact that an inductor (L D ) is coupled to the source of the shunt switch ensuring stable operation. 
     This regulator is particularly well suited for use in spacecrafts where a number of power supply units, in each of which the power supply is constituted by a specific solar array, are used to supply power to the electrical load.

Abstract: A direct current voltage is applied between an anodic portion containing an oxidizing catalyst provided on one surface of a proton conductive solid electrolyte which separates the flow path of the gas to be treated into two parts, and a cathodic portion containing a reducing catalyst provided on the other surface of the solid electrolyte, the reducing catalyst comprising at least one selected from oxides of elements of Group 5A, Group 6A, and Group 7A of the periodic table, palladium, palladium alloys, transition elements carried on alumina, cerium oxide, and La 1-x Sr x Co 1-y Fe y O₃ (where, 0≦x≦1, 0≦y≦1), while bringing a gas containing water vapor into contact with the anodic portion and bringing a gas containing nitrogen oxides into contact with the cathodic portion. As a result, the water vapor is electrolytically oxidized into protons and oxygen on the anodic portion, so that the protons having been transported to the cathodic portion can be utilized to reduce nitrogen oxides by the reducing power of hydrogen. The method efficiently reduces nitrogen oxides in a gas even under an oxidizing atmosphere.

Abstract: In an electromechanical engraving system, rotogravure calibrating apparatus automatically adjusting the engraving operation of an engraving-head stylus (21) of the system in real time by calibrating a stylus-actuating engraving signal according to a calibration factor relating printed image density to engraved cell depth for a designated engraving screen ruling corresponding to printed image resolution. The calibrating apparatus comprises a cell observation (41,46,48) and measuring device (47) which obtains data for calculating cell size by imaging the form of individual test cells engraved by the stylus into the surface of a rotogravure printing cylinder (C), and an engraving signal calibrator which adjusts engraving signal control parameters according to the cell size calculation and to the calibration factor. The engraving signal calibrator derives an image-density/cell-depth reference characteristic computed according to cell size data from cells engraved to correspond to a representative series of test image densities at the designated screen ruling, and computes the calibration factor as a correction of the image-density/cell-depth reference characteristic, generating engraving signal gain data which accordingly adjust the engraving signal actuating the stylus. The engraving signal is rapidly and automatically adjusted through a simplified calibration of the stylus-actuating engraving signal, stabilizing stylus lateral displacement adjustments for consistency among printing operations.

Title: Method and apparatus for controlling a press.
Inventor: O'BRIEN MICHAEL J
IPC: B30B15/26
Filed: 1993-01-07
Abstract: A process controller disposed to monitor and control a press. The controller monitors an appropriate variable at the press representative of the force produced at the workpiece upon which the press is operating, and compares this force to historical force data associated with the position at which the force was sampled. The historical data is stored in the form of control arrays, where the control arrays are calculated based upon one or more signature arrays stored during satisfactory press operations upon a similar workpiece. The calculation of the control arrays takes into account the deviations in the variables monitored at the press, which may include force and position. While monitoring the press based upon the HIGH and LOW control arrays, each force value is compared to the values in the HIGH and LOW control arrays at the time of sampling. The press controller is configured to monitor and control a high speed press and provides control functions during the particular press cycle in which unacceptable sample is taken.
