Patent CA-2039664-A1 (CA)
Inventor: GRBAVAC ROGER
IPC: E21D20/02
Filed: 1991-04-03
Abstract: A barrier for use with a rod extending into a bore having a cross sectional dimension, formed in a structure.          The barrier is located on one side of a fluid supply in the bore.  The barrier includes a sealing portion adjacent the fluid supply, the sealing portion has a flexible flange in sealing contact with the bore.  A tube is connected to the sealing portion and has a rod passageway formed there through.  A diameter of the tubular portion is smaller than the cross sectional dimension prior to insertion of the rod, and expands to conform to the cross sectional dimension in response to insertion of the rod.  A rupture portion is connected to the tubular portion, and seals the rod passageway to limit a passage of fluid therethrough prior to insertion of the rod.  The rupture portion is adapted to rupture in response to penetration by the rod.  The barrier may be used in conjunction with a dynamic earth anchor, to prevent passage of the grout to between the anchor and the bore.

Abstract: Connector assemblies for electrical components include a base frame having opposing side walls and opposed pairs of interior walls which are disposed parallel to the side walls.          The interior walls define a mounting hole which is sized and configured to receive an individual one of the holders.  The interior walls are interiorly spaced from their respective side walls so as to establish a relief slot therebetween.          The side walls of the base frame are provided with vertically separated locking tabs and mounting flanges.  During mounting of the connector assembly to the supporting structure, the locking tabs will be inwardly resiliently displaced until such time that they each clear the edge which defines the mounting space in the supporting structure for the connector assembly.  At that time, the locking tabs will resiliently return to their "normal" condition.  As a result, the supporting structure will be lockably positioned between the vertically separated locking tabs and mounting flanges.

The segmenter and preprocessor (14) output is fed to a feature extractor (16) which comprises a first layer of a Neocognitron.   The feature  extractor  (16)  output  is  fed  to  a  pattern recognizer  (18)  which comprises layers 2 and 3 of the Neocognitron.   The pattern recognizer  (18)  produces as output a real valued vector representation which encodes the object to be identified.  This vector representation is fed to a classifier (20) which comprises a backpropagation neural network.  The pattern recognition system (10) can classify large numbers of objects from raw sensor data and is relatively translation, rotation and scale invariant.

Title: Method and apparatus for accessing a nonvolatile memory
Inventor: HOOPER WILLIAM J
IPC: A61N1/37
Filed: 1991-06-26
Abstract: METHOD AND APPARATUS FOR ACCESSING A NONVOLATILE MEMORY                        ABSTRACT A method and apparatus for accessing a nonvolatile, electrically erasable programmable read only memory (EEPROM) following hermetic closure of a device containing the EEPROM. In specific application, the EEPROM is associated with other circuitry within the hermetically sealed enclosure and accessed by a direct connection to a feedthrough pin extending through the hermetic enclosure.  Following hermetic sealing, the memory is still accessible with low voltage and coded pulses for programming the memory in any desired fashion having utility with respect to the other circuitry and the overall function of the hermetically sealed device.     In the implantable medical device field, the invention may be utilized to program in the device serial number or similar data (after all quality and reliability tests are concluded) which may be telemetered out of the device on command of an external programmer/transceiver in order to identify the device.  In a specific application, a rate responsive implantable demand pacemaker, an activity sensor mounted within the hermetically sealed enclosure is electrically connected to the EEPROM and other operating circuitry.  At final test, the output of the activity sensor may be checked against specific levels of mechanical activity input applied to the exterior of the enclosure by observing the pacing rates developed from the sensor signal values, calculating a gain factor, storing the gain factor(s) in the EEPROM for adjusting the activity sensor derived pacing rate through its normal range of response.  This trimming of the response of the activity sensor minimizes the number of completed medical devices that fail to meet specification tolerances and allows those tolerances to be narrowed to assure relatively consistent variations in pacing rate as a function of applied mechanical force to the exterior of the hermetically sealed enclosure.  The EEPROM stored factor(s) may be entered only through the dedicated feedthrough and the programming circuitry. i once the factor(s) is stored and its accuracy is confirmed by retesting the pacing rate, the dedicated feedthrough pin is removed or rendered inaccessible. Normal programming of volatile random access memory (RAM) by use of the external programmer/transceiver cannot be employed to alter the contents of the EEPROM.  Moreover, the nonvolatile EEPROM memory would not be subject to change or loss caused by cold storage of the device prior to implant or electrical interference encountered if the patient undergoes cautery during surgical procedures or i defibrillation procedures, electrostatic discharge or high levels of electromagnetic interference (EMI).

Title: Process for the preparation of alkyl polyglycosides
Inventor: KAHSNITZ JOHN
IPC: C09K23/56
Filed: 1992-05-20
Abstract: ABSTRACT          The invention relates to a process for the preparation of alkyl polyglycosides containing C8-to 18-alkyl radicals by reacting alkyl glycosides containing C1- to C6-alkyl groups and alcohols having 8 to 18 C atoms.  The process of transglycosyla-tion is carried out in a reaction column and not in a stirred reactor.  This improves the space-time yield of the process and reduces the thermal stress on the products thus producing products having improved colour characteristics.  The products are useful as surfactants, for example for household and cosmetic applica-tions.

Title: Variable tone primitive style drum
Inventor: THOMAS ALLAN T
IPC: G10D13/02
Filed: 1992-07-02
Abstract: In a primitive style hand-held drum consisting of a rigid wooden frame over which an animal rawhide is stretched and laced to produce a taut membrane which produces a drumming sound when struck with a drumstick. The tone produced by a primitive drum is affected by the original tautness of the rawhide, but more importantly by subsequent temperature and humidity changes which cause the rawhide to expand or contract and change the tone of the drum. In this invention, the outward appearance of a drum is similar to a primitive style drum. The drum is held by the lacing on the back of the drum with one hand and struck with a drumstick with the other hand. In this invention, the frame of the drum is split at one location and the frame may be expanded or contracted by mechanical means to increase or decrease the circumference and so the tautness of the rawhide and the desired tone of the drum. A further novelty of this invention is that by mechanical means an extended lever is activated by the fingers of the hand holding the drum so that the tone of the drum may be changed as the drum is being played.
