Title: Plastic molding compound treated with an antistatic agent
Inventor: BERGNER KLAUS-DIETER
IPC: C08J7/04
Filed: 1991-05-10
Abstract: ABSTRACT OF THE DISCLOSURE          Plastic molding compound treated with an antistatic agent A plastic molding compound consisting of a thermoplastic or a thermosetting plastic and an antistatic agent, said antistatic agent being a mixture of a compound of formula I:                                           (I) and a compound of formula II:                                             (II) is distinguished by a good antistatic property, even when the amounts used are small, and by good physical and optical properties, on account of the increased effect due to synergism between the compounds of formulae I and II.   Compared with the individual components, antistatic agents consisting of a synergistic mixture of compounds of formulae I and II are more stable on storage, easier to proportion and easier to incorporate.

Patent CA-2043831-A1 (CA)
IPC: H04N5/208
Filed: 1991-06-04
Abstract: An outline compensation apparatus for a television receiver includes a circuit for detecting outlines of regions of a picture, expressed in a video signal, and a velocity modulation circuit for effecting outline enhancement in response to an output signal produced from the outline detection circuit.  The amplitude of that output signal is controlled in accordance with one or both of a contrast adjustment signal and a sharpness adjustment signal that are used to process the video signal in order to modify the degrees of contrast and sharpness of definition of the picture, respectively.          The operation of the outline compensation apparatus is thereby made to effectively complement any increase or decrease of display contrast and/or sharpness that results from the application of the contrast adjustment signal and sharpness adjustment signal, enabling the user to more easily adjust the television receiver to obtain a clear and natural-looking displayed picture.

Abstract: ABSTRACT OF THE DISCLOSURE     Integration and packaging of monolithic microwave integrated circuits (MMIC) components is facilitated by using a motherboard comprising high resistivity silicon, which having a thermal conductivity three times that of gallium arsenide.   Ultra high purity,  uncompensated silicon preferably is used.   Anisotropic etching of recesses in the motherboard facilitates precise place-ment of the MMICs in the recesses,  enabling use of automated die and wire bonding techniques to reduce required assembly time substantially.  Using a silicon motherboard also ultimately enables incorporation of required control circuitry.   The silicon motherboard also transmits RF energy well, a useful characteristic particularly in C-band and X-band applications in which microstrip is used,  though other transmission media function well at even higher frequencies.

Abstract: A strobe alarm circuit utilising an optocoupler in the DC-to-DC converter portion of the circuit for repetitively connecting and disconnecting an energy-storing inductor across a DC power source. The light-emitting diode portion of the optocoupler is connected in parallel with a resistor connected in series with the inductor for continuously monitoring the current flowing through the inductor; when the inductor current has attained a particular value at which the voltage drop across the resistor is sufficient to turn on the LED, the switch portion of the optocoupler is turned on and disconnects the inductor from across the source. After a short interval determined by the parameters of the optocoupler and associated circuitry. the cycle is repeated.

IPC: E06B1/62
Filed: 1991-12-20
Abstract: A one-piece metal frame fin is locked to the wooden frame members of a window unit by exterior cladding.  A notch in the frame members receives the inner portion of the nailing fin while the outer portion of the fin is recessed into the wood when the fin is in its closed position for storage, transport and use in abutting frame members of multiple window units.  An L-shaped corner nailing fin is carried on one of the frame fins and can be pivoted into locking engagement with the adjacent frame fin during installation of the window unit.  In the case of joined multiple window units a mullion cover extends over the adjacent ends of the frame nailing fins and is locked to the outer nose portion of the exterior cladding.  Use of foam sealing strips eliminates the need for on the job site caulking.

Abstract: Connector for electrical contact on an anode sheet of a polymer-electrode lithium generator which consists of one or more multilayer electrochemical cells. The cell comprises at least one sheet based on lithium with a thickness lying between approximately 1 and 50 microns, forming the anode and its collector and furthermore includes a cathode and its collector as well as the polymer electrolyte. One side end of the anode sheet extends beyond the corresponding ends of the cathode and of the collector to form an overhang region. A metallic layer consisting of at least one rigid metal which is compatible with lithium is in electrical contact with the side end of the anode sheet but without electrical contact with the other components of the cell. The metallic layer constitutes the external terminal of the generator when it is bare. According to one variant, an intermediate conducting and cohesive metallic region, consisting of lithium or lithium-rich ductile alloys is in intimate contact with the side end of the anode sheet, and the abovementioned metallic layer is therefore in electrical contact with the side end of the anode sheet via the intermediate lithium region. Generators fitted with such a contact connector as well as a method of preparing these contact connectors are described. <IMAGE>

Title: Naphthalene alkylation process
Inventor: ASHJIAN HENRY
IPC: C07B61/00
Filed: 1991-04-04
Abstract: Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite which contains rations having a radius of at least 2.5 .ANG.. Cations of this size may be provided by hydrated rations such as hydrated ammonium, sodium or potassium rations or by organoammonium rations such as tetraalkylammonium rations. The presence of the bulky rations in the zeolite increases the selectivity of the catalyst for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.  The zeolite may be treated to reduce its acid activity.

Title: Method for continuity logging
Inventor: KROHN CHRISTINE E
IPC: G01V1/42
Filed: 1992-10-28
Abstract: ABSTRACT OF THE DISCLOSURE        A drill  bit drilling a  borehole  is used as a strong  high  frequency,   subsurface  seismic  source  in combination with at  least one receiver  in a preexisting borehole  to  determine  the  continuity  of  a subsurface formation layer extending between the borehole being drilled by the drill bit and the borehole in which the receiver is located.  The receiver(s) in the preexisting borehole may be any  conventional  seismic  receiver  or  receivers,  such  as hydrophones or geophones.   The receiver or receivers are positioned in the preexisting borehole at a depth adjacent the formation layer whose continuity is to be determined. The depth (position), velocity and thickness of the layer is determined from a conventional well log of the preexisting borehole.   A frequency power spectrum for a preselected frequency range (the range is selected based on the logging data)  may be computed from the  signals  recorded by the receiver(s). Several  such spectra may be computed from signals recorded for several different time intervals and then summed to increase the signal-to-noise ratio.  A large amplitude in this power spectrum (or the detected signals) is indicative of a low velocity layer that is continuous between the drill bit source and the borehole containing the receivers.
