Patent CA-2031101-A1 (CA)
Inventor: ALLEY ROBERT P
IPC: H01H9/54
Filed: 1990-11-29
Abstract: A microprocessor-based relay system is used in combination with relay contactors and a control circuit therefor to protect an electric motor from overload currents in addition to phase faults, ground faults, load losses, and load jams. The microprocessor is provided with a data base comprising thermal characteristics of the motor during heating and cooling. The heating data comprise current versus time curves stored as a look-up table for which each data point represents a thermal limit, i.e., the maximum time the motor is permitted to operate at a particular current level. The cooling data comprise motor cooling rates. Phase currents are sampled at preselected fixed time intervals during a predetermined period thereof, and an average motor current value is calculated therefrom. A thermal sum, which is initialized at zero upon first starting the motor, is adjusted depending on the average motor current value relative to a predetermined overload current value. The average motor current value is used as an index to the heating curve look-up table. If the thermal sum exceeds the corresponding thermal limit in the look-up table for a predetermined time interval, then an overload condition is indicated, and the relay is tripped.

Abstract: An apparatus and method by which permeable contact lenses (19) may be cleaned through electrokinetic phenomenon is disclosed. The apparatus includes an receptacle 20 in which a lens is supportively aligned between terminals (40) by a member (50) or members (50, 51) made from a pliant transmission media. As aligned, an electric current will be focused to flow only through the lens (15) in order to efficiently and quickly decontaminate the lens. At least one surface (16) of the lens (15) is in intimate contact with a complementary shaped surface (50b) of a transmission media member (50). The other lens surface (18) may be in similar contact with an appropriately shaped surface (51b) of another transmission media member (51) or may be in contact with an electrically-conductive fluid (70) which either directly contacts a terminal 40 or indirectly contacts it through a reduced size media member (51). Again, one or each transmission media members (50, 51) may be indirect contact with the respective terminals (40) or through the intermediary of a fluid (36) connection. Two receptacles (20) may be mounted within a housing (12) embodying suitable circuitry (14) feeding terminals (40).

Title: Reflux fluid heated patient line
Inventor: VERKAART WESLEY H
IPC: F28D7/14
Filed: 1991-06-19
Abstract: A heat exchanger useful for supplying infusates over substantial distances uses an extrusion which provides a central tube for carrying an infusate and two outer channels for carrying a heat exchange fluid. A first of the channels carries the heat exchange fluid from an inlet end to an opposite end and the other of the channels returns the heat exchange fluid to the inlet end. An end cap at the inlet end is easily connected to a source of heat exchange fluid and communicates with the channels. An end cap at the opposite end receives the heat exchange fluid from the first channel and redirects it to the second channel. Both of the end caps have connectors for facilitating connection with lines from a source of infusate and a patient.
Patent CA-2045022-A1 (CA)
IPC: H04M3/02
Filed: 1991-06-19
Abstract: Apparatus is disclosed for use in a key set interface to overcome the incompatibility between key sets and tip and ring devices. The interface apparatus rejects ringing voltage and tip and ring loop current intended to be supplied on a first pair of conductors, the TR-pair. The interface further includes apparatus adapted for bi-directional communication of supervisory and control signals. In a preferred embodiment of the invention, a second pair of conductors, the service pair, transports bi-directional supervisory and control signals as well as operating power supplied by a key system controller for non-TR devices. Additionally, a transceiver adapted for sending and receiving voiceband information over the first pair of conductors isincorporated into the interface. An advantage of this key set interface is that operation of a key telephone set does not interfere with the operation of a tip and ring device bridged onto the first conductor pair.

Title: Improved innerseal for a container and method of applying
Inventor: MCCARTHY THERESA A
IPC: B65D77/38
Filed: 1990-01-17
Abstract: An easily removable innerseal for a container and method of application relates to an improved arrangement having a body portion (22) adapted for fitting over the upper rim of a container and a flexible element (24) attached to the body portion for a user to grip. The body portion is provided with a lower bonding layer, which includes a first bonding portion (26) and a second bonding portion (28) adhered to the first portion, and a layer (30) to prevent fluid from passing therethrough. The bonding force between the first and second bonding portions is designed to be weaker than the bonding force between the bonding layer and the container. In addition, the rupture strength of the first bonding portion is less than either of the bonding forces. As a result, the force required to remove the innerseal from the container is not dependent upon the amount of heat applied during sealing, because delamination will occur between the two bonding portions in an area over the container rim (14), leaving a residue of the first adhesive portion attached to the rim. By gripping the flexible element and pulling it upwardly, a user can remove the innerseal from the container without having to puncture or scrape the innerseal with a sharp object, which is frequently required to remove innerseals of the type commonly in use today. The method of application includes the steps of applying the body portion of the innerseal around the rim portion of a container and passing the container through an induction type heating station.

Title: Self-regulating heater utilizing ferrite-type body
Inventor: MCGAFFIGAN THOMAS H
IPC: H05B6/14
Filed: 1991-09-18
Abstract: A self-regulating heater is provided by placing a ferrite-type body member (16), which is highly lossy when exposed to a high frequency alternating magnetic field and has a predetermined curie temperature, on or around a central conductor (14) which is connected or is adapted to be connected to a power source (17) which provides high frequency alternating current to the conductor. The current passing through the central conductor (14) produces a magnetic field around the conductor, which causes the ferrite-type body to be heated by internal loses to its Curie temperature. The heater self-regulates at the Curie temperature of the ferrite-type body. The power source (17) is preferably a constant current, impedance matched power source. The ferrite-type body member can be ferromagnetic or ferrimagnetic. The ferrite-type body is preferably ferrimagnetic, such as ferrite beads, rings, and the like, which heat by hysteresis losses.

Abstract: A propeller control system comprises a phase controller (11) having a phase control gain to control a propeller phase relationship, free air turbulence detection means (7, 9) and a gain controller (8) for varying the phase control gain in response to detected free air turbulence such that in the presence of turbulence a low gain is selected and in the absence of turbulence a high gain is selected.
