Patent NZ-221237-A (NZ)
Title: Back-up overtemperature protection in bimetal thermostat
Inventor: BLACKBURN ARTHUR MALCOLM
IPC: H01H37/00
Filed: 1987-07-28
Abstract: An element protector control for protecting the electrically powered heating element of a kettle against overheating has primary and secondary (or back-up) modes of operation. The primary protection mode utilizes a dished, snap-acting bimetal (22) which is oriented so that the side of the bimetal which is convex when the blade is cold faces the heating element head (24), and the bimetal is held in close thermal contact with a rear surface of the element head. The bimetal determines the condition of a pair of switching contacts (32, 33) provided in the control. The bimetal is mounted in a carrier (21) which is spring biassed towards the element head and, for providing the secondary protection mode, the carrier is formed of a thermoplastics material so that in the event of failure of the primary protection in an overtemperature situation so that the element temperature continues to rise, the carrier will collapse towards the element head, and the collapse of the carrier is arranged to disconnect the control from its power supply terminals.

Title: Dental treatment system using abrasive particles carried by a fluid stream
Inventor: GALLANT BEN J
IPC: A61C3/02
Filed: 1993-03-26
Abstract: A system of treating teeth or associated tooth structure uses abrasive-laden fluid stream. The system provides air at high pressure to a manifold with selectively operable valves delivers fluid at a selected pressure to a device for mixing the fluid with abrasive and delivers the air/abrasive mix to a hand-held device for application of an abrasive-laden stream to a tooth or associated tooth structure. Priming air at a relatively low pressure pressurizes the air/abrasive device. A flow path for pure air bypasses the air/abrasive device. A selective control allows for optional delivery of a stream of air or air and abrasive to the tooth or associated tooth structure. Upon termination of a treatment, the pure air is diverted through a purge line to purge the system downstream from the abrasive device of abrasive particles. A vacuum removes abrasive particles and debris from the region of the mouth of the patient during and after the abrasive treatment operation. The abrasive delivery device includes a hand-held nozzle having fluid ports operable by the fingers of the operator to control the instrument. The vacuum includes a rigid, disposable collection chamber for sterile disposal of the abrasive material and debris. Pressure regulating and relief means insure instantaneous change from one pressure level to the next.

Title: Implantable osmotic delivery device with self adjustable exit port through which an agent is extruded
Inventor: GUMUCIO JUAN C
IPC: A61K9/52
Filed: 1998-03-10
Abstract: Provided is a delivery device having a first chamber containing an osmotic agent (20, 320), a membrane forming a wall of the first chamber through which fluid is imbibed by osmosis (60, 360), a second chamber containing a beneficial agent to be delivered (40, 340), and a moveable piston separating the two chambers (30, 330).  In fluid communication with the second chamber is an orifice which comprises a slit valve (50, 354). In the presence of pressure, the beneficial agent pushes through the slit, opening up a channel for delivery of the beneficial agent and creating flow.  Because the slit remains closed in the absence of flow (or when the pressure is below the pressure required to open the slit), back diffusion of external fluids is eliminated when the slit is closed, which prevents contamination of the beneficial agent in the second chamber by external fluids.  In addition, forward diffusion of the beneficial agent out of the capsule is prevented when the slit is closed. The slit valve opens only to the minimum dimension required to allow the flow generated by the osmotic pumping rate.  The slit valve also allows a flow path to open around any obstruction in the slit valve to prevent clogging.
