Patent CA-2004241-C (CA)
Inventor: PRUETT DONALD N
IPC: H02G15/08
Filed: 1989-11-30
Granted: 1999-07-27
Abstract: A ceramic cased capacitor and related method of construction  are provided,  wherein  the  capacitor  is substantially impervious to moisture penetration and is adapted  for  attachment  to  conductive  leads  with superior lead pull strength.   The capacitor comprises at least two conductive plates encased at a selected gap   within  a  substantially  monolithic  casing  of selected   dielectric   material   such   as   a   ceramic material.   The  plates  each  include  a tab  projecting beyond an adjacent margin of the other plate.  Recessed seats are formed in the casing as by drilling to bridge at least partially into the tabs.  Conductive lead ends are attached to the capacitor by soldering within the recessed seats, thereby securely anchoring the leads in a   manner substantially   impervious   to   moisture penetration.  The thus-formed capacitor may be used in a wide range of electronic circuit applications without requiring a conventional encapsulating outer jacket or coating of insulating material.   By virtue of omission of the encapsulating jacket, the capacitor can be used in  high  temperature  environments,  and/or  in  high voltage   applications,  without   concern   for  jacket deterioration,  deterioration  in  insulation resistance, or   delamination   of  the  jacket   relative  to  the monolithic casing.

Title: Rate adaptive cardiac pacer system having living cell tissue for sensing physiologic demand
Inventor: HAUSER ROBERT G
IPC: A61N1/365
Filed: 1990-04-26
Granted: 1995-01-31
Abstract: Described herein  is a  cardiac pacer pulse generator and lead combination in which sinus node cell tissue is  harvested or cultured and  appropriately affixed  to the  distal  end  of  the pacing lead to generate  electrical depolarization  signals whose rate changes with blood-oxygen levels and hormonal activity.  The lead  includes  a   sensing  electrode   for  picking   up  these depolarization signals  and applying  them to  the rate  adaptive pacemaker.  The pacemaker then functions to produce  heart tissue stimulating pulses  at a  rate dictated by the body's physiologic demand.

Title: Cross-polarization interference canceller
Inventor: MIZOGUCHI SHOICHI
IPC: H04B7/02
Filed: 1991-01-22
Granted: 1995-01-17
Abstract: In a cross-polarization interference canceller for use in a digital radio communication system which transmits digital modulated signals over radio frequencies having planes of polarization orthogonal to each other, signals from the interfering polarized wave are sampled with a frequency equal to double the frequency of the affected polarized wave and, after latching the sampled signals with the frequency of the symbol rate, interference cancelling signals are generated by adding the products of their multiplication with control signals.  Therefore, the digital multipliers and the digital adders for generating the interference cancelling signals can be operated at low speed.

Title: Speaker-independent label coding apparatus
Inventor: BAHL LALIT R
IPC: H03M7/30
Filed: 1992-02-04
Granted: 1996-08-13
Abstract: The  present  invention  is   related  to   speech recognition and particularly to  a new type of vector quantizer  and  a new vector quantization technique  in which the  error  rate  of  associating a  sound with an incoming  speech  signal  is  drastically  reduced.   To achieve this end, the present invention technique groups the feature vectors in a space into different prototypes at least two of which represent a class of sound.  Each of the prototypes may in turn have a number of subclasses or  partitions.   Each  of  the  prototypes  and  their subclasses may be assigned respective identifying values. To identify an incoming speech feature vector, at least one of the feature values of the incoming feature vector is compared with the different values of the respective prototypes,  or the subclasses of the prototypes.   The class of sound whose group of prototypes, or at least one of  the prototypes,  whose  combined value most closely matches the value of the feature value of the feature vector is deemed to be the class corresponding to the feature vector.  The feature vector is then labeled with the identifier associated with that class.

Title: Easy-open tear strip lid
Inventor: LANDIS H RICHARD
IPC: B65D43/02
Filed: 1993-03-18
Granted: 2005-01-04
Abstract: A reclosable plastic lid having a peripheral flange with a substantially annular projection that engages an annular shoulder on a container sidewall to retain the lid initially on the container full of contents. The flange is formed with a weakened portion defining a tear strip which removes to detach spaced portions of the flange along with portions of the annular projections leaving flange portions which are folded upwardly about hinge lines to retracted positions out of locking engagement with said annular shoulder. With the tear strip removed and the remaining flange portions pivoted outwardly toward horizontal positions, it is much easier to remove the lid from the container. When the lid is re-applied to reclose the container, the remaining attached, flange portions are pivoted down into engagement with container shoulder to retain the lid on the container and thereby, prevent spillage of the container's contents.

Title: Casting of metal objects
Inventor: LEGGE RODNEY A
IPC: B22C9/08
Filed: 1991-11-04
Granted: 2006-01-03
Abstract: The mould assembly comprises mould segments of generally non-thermally conductive material which define a mould cavity for receiving liquid metal through at least one ingate. A thermal extraction member of a high thermally conductive material contacts a portion of the mould cavity through which heat can be extracted rapidly from said liquid metal and transferred to said thermal extraction member to establish positive thermal gradients in the casting and thereby promote directional solidification. The heat extraction from said liquid metal may optionally be enhanced by heat extraction from said thermal extraction member. The mould assembly is also provided with a seal to selectively isolate the mould assembly from the liquid metal source to allow the mould assembly to be removed from the casting station to the cooling station before any substantial solidification has occurred, providing a more efficient use of the casting station.

Abstract: In a method to modify the chemistry of a portion of  the  surface  of an article,  the surface is placed adjacent an electrode in a plasma chamber, the distance to the wall of the chamber being at least five times the size of the electrode.  A plasma of very high power density is generated in a discharge volume surrounding the electrode so that the surface area closest to the electrode   receives   a  very   intense  plasma  which, diminishes with increasing distance from the discharge volume thus forming a chemical gradient on the article surface.   The preferred article is a tube having one closed end, and the gradient may be formed from either the closed end or the open end.  The gradient may be of decreasing    glass-like    character   or   decreasing plastic-like character.

Abstract: A locking pin (100) for use captively retaining a tooth (14) on an adapter portion (12) of an excavating tooth and adapter assembly has a primary wedge member (110) with an integral spring (120) extending upward from the member's distal end (116). A  first positive stop means (130) extends from the wedge member (110) while an opposing second positive stop means (122) extends from the integral spring (12). After insertion, the locking pin (100) prevents separation of tooth (14) from adapter portion (12) while the first and second positive stop means (130, 122) prevent accidental loss of the locking pin (100) from the assembly. To remove the locking pin, a force sufficient to separate the fast positive stop means (130) from the pin (100) is exerted to drive the pin (100) from the assembly. In another embodiment, the integral spring extends from a lateral surface of the locking pin (700, 800). In another embodiment, the locking pin (900) comprises stop means (910, 912) which are radially extendable by spring means (908).
