Title: Method of preparing a synthetic rutile from a titaniferous slag containing magnesium values
Inventor: GUEGUIN MICHEL
IPC: C22B7/04
Filed: 1987-12-17
Granted: 1991-09-10
Abstract: ABSTRACT          A synthetic rutile is prepared from a titaniferous slag, typically containing at least about 1.0 weight percent magnesium oxide and at least some portion of its titanium values as Ti2O3, by a method comprising contacting the slag with chlorine gas at a temperature between about 400°C-850°C such that the magnesium oxide and chlorine gas react to form magnesium chloride, and then removing the magnesium chloride from the slag, typically by washing the slag with water.  In one embodiment, the synthetic rutile can be further upgraded by subjecting it to either a caustic or acid leaching treatment.

Title: Thermodynamic printing method and means
Inventor: KUEHNLE MANFRED R
IPC: G03G15/32
Filed: 1988-02-26
Granted: 1991-12-24
Abstract: Abstract of the Disclosure In a method of printing on a printing medium a variable thickness ink dot pattern representing an original image in response to an incoming digital data stream, a printing member, e.g. a cylinder, is formed which defines a multiplicity of discrete, independently electrically chargable capacitor microcells adjacent to a printing surface of that member.  Selected ones of the microcells are activated in accordance with the incoming data stream so that the activated microcells are geometrically related to the dots in the pattern to be printed.  Then, electrical charges are deposited on the microcells selected for activation at controlled variable coulombic charge levels to create at the printing surface localized electrical fields of various strengths that are proportional to the print densities desired for the related dots in the pattern to be printed.  Following this, the printing surface is contacted by a two-component, voltage sensitive, thermoplastic whereby the ink, under the influence of the fields, is deposited on the printing surface only at the locations of the microcells selected for activation, with the thickness of each ink deposit being proportional to the strength of the field at that microcell, thereby to form a variable-thickness ink pattern on the printing surface.  That ink pattern is then transferred completely to the printing medium to provide a faithful hardcopy reproduction of the original image.  Apparatus for practicing the method are also disclosed.

Inventor: VOISINE JOHN T
IPC: G01R21/00
Filed: 1988-08-25
Granted: 1991-10-29
Abstract: Abstract of the Disclosure A voltage transducer in a watthour meter, for sensing AC line voltage across a load, includes a current transformer having its primary winding connected in series with a current-limiting resistor across the AC source. The transformer includes a secondary coil and a tertiary coil. The current through the secondary coil represents the sensed voltage and is signal conditioned through an integrator circuit for input to a solid-state watt transducer chip. An active circuit is connected across the tertiary coil, with an output feeding a compensating current into the input of the secondary coil. The active circuit includes an RC network at the output of the tertiary coil for providing a loop stability. A first non-inverting op amp amplifies the voltage output from the RC network to provide a phase correction, adjustable by a replaceable resistor connected between the inverting node of the first op amp and an electrical ground. An integrating op amp is connected between the output of the first op amp and the input to the tertiary coil to form a feedback circuit to reduce DC offset signals from the output of the first op amp. The primary coil of the current transformer is composed of an electric conductor wire coated with an electrically insulating layer to withstand impulse voltages of at least 6kV.

Title: Sealing arrangement

Granted: 1992-11-24
Abstract: ABSTRACT      A mushroom-shaped piston 10  is driven to reciprocate in a cylinder 20 by an annular driving part 70 extending around its stem. The driving part forms the "rotor" of a linear electric motor, the "stator" of which is provided by the cylinder.  The ends of piston are exposed to greater and lesser pressures P1, P2. During movement of the driving member relative to the piston against the bias of a spring 40, fluid flow through a passage 76 containing a one-way valve 60 generates an overpressure in a chamber between seals 30, 32, 34 and prevents leakage of fluid around the seal 30.  Figure 2 shows a modification in which the piston 110 has a central well 113, 114 containing a plunger 180 biassed by a diaphragm 140,    Here the overpressure is generated in the well and a passage 116 exposes a seal 131  to the overpressure to prevent leakage around the piston.

IPC: G03G15/22
Filed: 1989-04-21
Granted: 1993-07-06
Abstract: APPARATUS FOR ELECTRONICALLY MAPPING  FRAMES ON AN UPDATABLE MICROFICHE     ABSTRACT     An apparatus for electronically mapping an updatable microfiche includes a microprocessor-based analyzer programmed to control and evaluate optical scanning of the imaging frame areas arranged in generally parallel rows and columns, across the entire microfiche.  Optical photosensors are used to detect the presence of a frame mark within an expected region of an imaged area.  An electronic data mask retrievably stored in a mask table memory array is used to screen the output data from the sensors.  The mask table is derived from relative sensor position data collected during a scanning operation on a calibrated microfiche.  The calibration routine also determines average sensitivity levels of the sensors.  During an calibration scan on a standardized microfiche, the mask table data and sensitivity levels are used to determine whether valid frame marks were detected.  A look-up table memory array is used to store the results of an evaluation scan by storing which frames are imaged and which are available for imaging, thereby permitting non-sequential image development while preventing frame double exposure.

Abstract: Apparatus for discharging static electricity from the human body by ionizing air and utilizing the flow of ions from the apparatus into the surrounding environment to discharge the body. The apparatus utilizes two power supplies to raise two embedded electrodes positioned in a horizontal plane different voltagepotentials with respect to the body. The air is ionized by utilizing discharge electrodes of the opposite polarity positioned over each of the embedded electrodes which results in air ions being formed in a ion distribution above each embeddedelectrode. The embedded electrodes are positioned a predetermined distance from each other in the embedded plane. Within the region between the embedded electrodes, the ions recombine to form air molecules. The ions in the distribution layers above each embedded electrode drift toward this region under attraction from each other. As the ions move, ions of the same polarity as the body are repelled into free air by virtue of the presence of the static charge on the body. In free air, they eventually drift to a grounding point within the environment. This expulsion of the ions of the same polarity as the body discharges the static electricity from the body.
