Title: Anti-barking and anti-biting muzzle for dogs
Inventor: PAGLERICCIO FERNANDO PAULO
IPC: A01K25/00
Filed: 1995-12-29
Granted: 2003-01-21
Abstract: An anti-barking and anti-biting muzzle for dogs includes a muzzle portion formed from a pair of generally trapezoidal flaps of elastic material sewn together along the converging edges thereof, with the flaps being further divided by a seam along the longitudinal centerline thereof  to create  four panel members  of  the elastic material.   An elongated strap is connected at its ends to opposed seams of the muzzle portion.  The muzzle can be slid onto the snout of a dog and the strap fitted over the dog's head behind its ears.  The muzzle portion has a snug fit on the snout but the elasticity of the material allows the dog to open its jaws slightly for panting.  If the dog tries to open its jaws wider to bark or bite the four elastic panel members apply a force to the jaws to prevent them from opening wide.  The muzzle is not uncomfortable and it acts as a training aid since the animal associates the wearing of the muzzle as a form of punishment for barking or biting.  It soon learns to stop barking or biting when it event sees the muzzle.   The muzzle can be quickly removed by applying an upward or lifting force on the strap behind the ears, important if the dog is relied upon to provide security for a human attendant.

Patent CA-2189851-C (CA)
Inventor: MUTERSPAUGH MAX WARD
IPC: G05F1/573
Filed: 1994-09-13
Granted: 2000-01-25
Abstract: The present invention concerns a voltage regulator wherein the series pass transistor and an amplification transistor are of complementary types. Supply current flows from the DC supply source through the emitter-collector path of the series pass transistor to the load. The amount of this current is controlled by a negative feedback control signal coupled from the regulated output voltage to the base electrode of the amplification transistor, which in turn drives the base of the series pass transistor. The emitter electrode of the amplification transistor is coupled to a voltage which is less than the regulated DC output voltage so that drive requirements for the pair of transistors is reduced.

Title: Rf link control of satellite clocks
Inventor: CUMMISKEY PETER
IPC: G04R40/02
Filed: 1995-06-01
Granted: 2003-08-12
Abstract: A system and method for maintaining a precise time standard among a system of orbiting satellites is disclosed. In an illustrative embodiment (the figure), atomic clock data is circulated among the satellites (2, 4, 6) via RF crosslinks (10). Each satellite uses the received data as input to a Kalman process which acts to minimize the means squared error among the satellite clocks to form a set of "ensemble clocks". The resulting ensemble clock values are then transmitted (12) to an earth station (8) where an offset between the ensemble clocks and Universal Time is computed. The offset is transmitted (14) from the earth station to the satellites where it is used by the satellites to lock their on-board clocks to Universal Time, thereby creating a corrected system time. The corrected system time is transmitted. via RF crosslinks (10) to satellites not having operational on-board clocks. The satellites without atomic clocks employ phase locked loops to anchor their clocks to the corrected system time as it is received over the crosslinks.

Abstract: A combination gas drying and reservoir apparatus includes a reservoir, a membrane dryer disposed inside the reservoir and a control scheme that reduces the amount of gas lost as sweep gas from the dryer.  The reservoir has an inlet flange that receives moisture  laden gas  from a  compressor,  an outlet flange from which dried gas discharges to a pneumatic system and a purge flange.  The dryer includes a vessel encasing a membrane unit between its inlet and outlet ends.   A purge port of the vessel communicates with the purge flange to form a purge channel.  The inlet end of the vessel is connected to the inlet flange from which it receives the moisture laden gas.   The moisture laden gas then flows into the membrane unit.   Sweep gas that has permeated through membranes flows from  a  sweep  space  defined  between  the  vessel  and  the membrane unit to the purge channel.  Dried gas flows out of the membrane unit through the outlet end of the vessel into the reservoir.  The control scheme includes a purge valve and a mechanism for controlling the purge valve.   Connected to the purge flange,  the purge valve can be closed to prevent sweep  gas  from  exhausting via  the  purge  channel  to atmosphere.   When the compressor is unloaded,  the mechanism closes  the purge valve  thereby preventing  sweep  gas  from expelling to atmosphere.  When the compressor is loaded, the mechanism opens the purge valve thereby allowing sweep gas to exhaust to atmosphere via the purge channel of the apparatus.

Abstract: The invention provides a wound dressing (1) comprising a wound contacting sheet (4) laminated to one side of an absorbent layer (3) of water-swellable absorbent material such as a polyurethane. A liquid water-impermeable backing layer (2) is laminated to the other side of the absorbent layer (3).  The wound contacting sheet is provided with one or more slits (5) therein. Expansion of the absorbent layer (3) due to absorption of wound exudate causes the slits (5) in the wound contacting sheet (4) to expand, thereby allowing passage of high flow rates of wound exudate. If the flow of exudate falls, then the slits close, thereby avoiding excessive drying of the wound surface.
