Patent CA-2165623-A1 (CA)
Title: Power Factor Correction Circuitry
Inventor: BOGDAN ALEXEI
IPC: H02M1/42
Filed: 1995-12-19
Abstract: A power factor correction circuit for use with a power supply. The power supply has an input for receiving an AC input signal, a rectifier for producing a rectified AC signal and an output stage for outputting a DC output signal for driving a load coupled to the output stage. The power factor correction circuit comprises an input port coupled to the rectifier for receiving the rectified AC signal; and an inductor coupled to the input port for storing energy in response to excitation by the rectified AC signal. The excitation of the inductor is controlled through the opening and closing of a switch by a controller. A capacitor is coupled to the inductor and charged by the energy stored in the inductor when the switch is opened to produce the DC output signal. The power factor correction circuit includes a diode for blocking the charge path between the input port and the capacitor and also allowing the controller to boost the charge level on the capacitor.
Patent CA-2165903-A1 (CA)
Inventor: CHEN NING
IPC: C08G18/83
Filed: 1995-12-21
Abstract: This invention relates to improved crosslinking systems for polymeric dispersions and solutions having suitability for coatings, adhesives and use in many other applications.  These systems are based upon crosslinkable polymers having a plurality of activated keto methylene groups, e.g., a beta diketone such as an acetoacetate or a keto cyano  methylene functional groups and a crosslinkable component comprising an aldimine.  A sufficient amount of the aldimine curing agent is used to effect reaction with the polymer containing the activated keto methylene groups and cure thereof.  The improvement in the crosslinking system resides in the utilization of a monoaldimine having only one aldimine group and no other methylene reactive group as a crosslinking agent.  Another improvement variation to that previously suggested comprises a redispersible polymer(s) containing activated methylene functionality and combined with the monoaldimine and the use of heterocyclic aldimine.
Patent CA-2166548-A1 (CA)
Title: Improved patient/nurse call system
Inventor: JENNINGS ROBERT J
IPC: G08B25/12
Filed: 1994-07-12
Abstract: A patient/nurse call system (10) for a hospital includes patient stations (18) capable of generating hospital calls and a remote master station (32) which prioritizes and stores the calls. Hall units (28) outside patient rooms (14) identify the rooms (14) from which the calls originate and the type of call. Each patient station (18) allows selective retrieval and display of unanswered calls, and the system (10) further permits audio interconnection between any two of the stations (18, 32). Nurses-worn badges (26) transmit pulse-coded infrared signals which are received by receivers (121) at the patient stations (18) and in response, the system (10) generates identity and location signals which are stored at the master station (32). The nurse location and identity information may also be retrieved and displayed at any patient station (18). Receipt of a nurse's (11) infrared signal at a room station (18) automatically cancels a patient call originating from the room (14) and display thereof by the respective hall unit (28), while actuating a display (122) to indicate nurse (11) presence. Bed monitoring units (149) also interconnect to the patient stations (18) to generate signals related to bed status.

Title: A method of detecting incorrectly closed freezing frame liners, and a liner and a system therefor
Inventor: NIELSEN MOGENS
IPC: B65B57/02
Filed: 1995-07-19
Abstract: Carton liners are used in freezing frames for the preparation of large frozen blocks of fresh food material, e.g. fish fillets. The liners have a lid with skirt flaps to be closed upon filling of the liner, and care should be taken that the lid flaps be located at the outsides of the liner walls inside the freezing frame, as they may otherwise be embedded in the material to be frozen and thus disturb the regularity of the frozen block material. The same applies to corner flaps which, already by the mounting of the liner, should be folded to assume an exterior position. According to the invention, in order to ascertain a correct mounting and closing of the liners once they have been removed from the freezing frames, such liners are used which are provided with printed marking (A, B, C) on those outside area portions that are to be covered by exterior liner/lid flaps, and the closed liners are inspected for detection of any visible marking, which will be indicative of a potentially defect block product.

Inventor: JOHANNESSEN ARNE
IPC: G05D11/13
Filed: 1997-03-07
Abstract: A device (18) for measuring relative viscosity includes an apparatus (29) that can be movably mounted within a fluid reservoir (12) and a sensing system. The apparatus has two members (32, 34), with one member being more bendable than the other. When the apparatus is moving, the sensing system detects a differential bend between the members; the differential bend is related to the viscosity of a fluid when the fluid is included in the fluid reservoir in which the apparatus is movably mounted. The sensing system includes two spaced sensors (40, 42) which detect when magnets (36, 38) on the members pass the sensors. A timer provides a time lapsed between passage of one member past a sensor and passage of the other member past the other sensor. The time lapse is related to the viscosity of the fluid in the fluid reservoir. A controller controls the addition of a solvent to the fluid.
