IPC: B42D25/00
Filed: 1992-11-16
Granted: 1999-02-09
Abstract: An  extension  module   is  provided   for   tandem connection to  a base circuit card having an external sheet material  jacket  girding  said card.   The  module includes a module housing and a pair of spaced apart parallel support fingers extending from the housing.  The outer sides of said support fingers are configured for slidable insertion into corresponding spaced apertures in the rearward end of the base circuit card to engage inner surfaces of the jacket adjacent opposite side edges of the  jacket  of  the  card.   An  electrical  connector  is located between the support fingers and is adapted for mating connection  with  a  corresponding  electrical connector located at the rearward end of the base circuit card, when the extension module is connected to the base circuit card.  When the extension module is connected to the base circuit card by substantially full insertion of the  support  fingers  into  the  base  circuit  card  the engagement of said jacket embracing the fingers rigidly joins the extension module to the base card to form an integral extended circuit card.

Title: Faulted circuit detector having isolated indicator
Inventor: DUNK MICHAEL P
IPC: G01R31/58
Filed: 1991-06-21
Granted: 2000-12-19
Abstract: A faulted circuit detector (10) having an electrically isolated and remotely positioned indicator (14) detects fault currents in a monitored conductor (18). When a fault of a predetermined magnitude is detected, a light pulse is transmitted from the detector to the indicator via a fiber optic cable (15) where, upon receipt, the pulse is converted to an electrical pulse causing the indicator to indicate a "fault" state. A reset circuit (56) within the indicator resets the indicator at regular intervals to the "normal" state as long as a predetermined minimum voltage is present on the monitored conductor. The detector includes a temperature compensation circuit (150) and low pass filter circuit (160) so as to prevent misoperation due to varying ambient temperatures or high frequency transients. A test circuit (48, 50, 34) is also provided to allow service personnel to field-test the device with the monitored conductor in an energized state.

Patent CA-2089339-C (CA)
Inventor: BELUSA MANFRED L
IPC: F24F11/04
Filed: 1993-02-11
Granted: 2002-03-12
Abstract: An apparatus and method for space pressure control in high containment laboratories. The system comprises a volumetric air flow controller and a differential pressure controller. The differential pressure controller couples to the volumetric air flow controller. To establish negative space pressurization in the laboratory, the differential pressure controller generates a variable offset signal for volumetric operation. In response to the offset signal, the volumetric air controller controls the ducted supply air to the laboratory at a set shortfall compared to the ducted exhaust air flow. The shortfall of ducted supply air creates a negative pressure which is also sensed by the differential pressure controller. The differential pressure controller reduces the variable offset signal to zero once the desired negative pressure level is attained. To maintain the negative pressure level, the supply and exhaust air flow rates must remain equal. Any change in the negative pressure level is detected by the differential pressure controller which will generate the offset signal required to restore the negative pressure level. Furthermore, if the negative pressure level is completely lost, either by breach of the laboratory containment barrier or by equipment failure, then system 10 will generate the offset signal for volumetric operation.

Title: Electronic cancellation of ambient noise in telephone receivers
Inventor: BENNING ROGER DAVID
IPC: H04M1/60
Filed: 1993-09-29
Granted: 1996-12-17
Abstract: Noise reducing circuits for electronic receiving instruments, such as telephone receivers in headsets or handsets that are used in noisy locations, provide compensation of the set's receiver unit-to-error microphone transfer function toenhance the noise reduction. Further circuits provide pre-conditioning of the incoming voice signal to make the noise cancellation more effective. The tendency of these noise cancelling circuits to oscillate is substantially lessened by added circuitry which rapidly detects onset of oscillation and momentarily reduces thenoise cancellation without interrupting the incoming speech path altogether.

Patent CA-2141077-C (CA)

Filed: 1995-01-25
Granted: 1999-02-16
Abstract: The present invention provides a conveyor system for divergence and convergence, which is capable of always satisfactorily diverging or converging articles without regard to their size. When the roller axes 19 are orthogonal to the transport path 9, an article 60 to be transported is transported downstream by the rollers 16 without being sorted. When it is desired to sort the article 60, an angle changing device 30 is actuated to individually change the angles of inclination of the rollers 16, such that those rollers which are disposed in the upstream region are given a smaller angle of inclination, the angle of inclination being gradually increased. Diversion of the article can be effected such that it has its direction of orientation gradually changed from a smaller angle to a larger angle while it is gradually moved to one side by a smaller amount to a larger amount. The article 60 can be subjected not to an early (sharp) diverging action but to a sufficient diverging action; thus, it can always be satisfactorily diverged without regard to its size. It can always be satisfactorily converged by the reverse operation.

Title: Polyionic insoluble hydrogels comprising xanthan
Inventor: CHORNET ESTEBAN
IPC: A61K9/52
Filed: 1995-04-03
Granted: 1999-04-06
Abstract: A method for the preparation of insoluble hydrogels from the complexation of polycations and xanthan is reported. Stable hydrogels capable of retaining between 65 and 95% weight water were prepared particularly with chitosan and xanthan. The water retention and properties of the hydrogels were studied as a function of the degree  of  acetylation  of  chitosan  and  the  ratio chitosan/xanthan used in the preparation of the gel.          The chitosan-xanthan complex was used to immobilize biological material.  Hydrogels containing enzymes (for example endo-1,4-.beta.-xylanase and protease)  either as single enzymes or as a binary system have been prepared.          Immobilization  varied  between 85  and  98%.   The immobilized xylanase activity was significantly greater with respect to the free enzyme while the binary enzyme system promoted protease activity.   Other hydrogels prepared with polybasic drugs complexed to xanthan with or without chitosan have been prepared.  These complexes slowly dissociate  in acidic media  and provide  for sustained release of compounds in near neutral pHs.          Gels containing chitosan are stable in all physiological pHs and the immobilized molecules are released therefrom by diffusion.
