Patent CA-2146413-A1 (CA)
Title: Electrically operated actuator having a capacitor storing energy for returning the actuator to a preferred position upon power failure
Inventor: JATNIEKS GIRTS U
IPC: H02P7/00
Filed: 1995-04-05
Abstract: An electrically operated actuator stores power in a capacitor for returning the actuator output element to a preselected position upon power failure. The actuator has a controller having input power terminals connected across the capacitor and control terminals for controlling the power applied from the input power terminals to the motor which comprises the actuator's prime mover. A sensor monitors the presence of power provided to the controller's input power terminals. When failure of this power is sensed, the capacitor current flows to the controller, and the sensor applies signals to an override circuit of the controller causing the controller to apply current from the capacitor to the actuator motor in a way which drives the actuator toward the preselected position. A properly selected capacitor is capable of supplying adequate current over a period of time sufficient to return the actuator to the preselected position.

Patent CA-2151714-A1 (CA)
Title: Mobile communications method
Inventor: ITO SHOGO
IPC: H04W68/00
Filed: 1994-10-19
Abstract: In a mobile communications system wherein the transmission form changes in the course of the signal, high quality transmission of change information relating to the transmission form is obtained. To achieve this, information giving advance notice of a change is transmitted prior to transmitting the change information relating to the transmission form.      Even if a situation arises in which transmitted information has not been conveyed without error at a scheduled change time that was notified in advance, it is possible to cope with this situation by referring to the information giving advance notice of the change. This enables faulty paging and other defects resulting from erroneous changes of transmission form to be reduced.

Title: Laser Finishing and Measurement of Diamond Surfaces
Inventor: NAGY BELA G
IPC: B23K26/00
Filed: 1995-11-14
Abstract: A combination measuring and ablation laser apparatus is provided which generally includes an ablating laser, a profilometer laser, an automatic feedback control unit and electro-mechanical positioning apparatus.  The combination measuring and ablation laser apparatus can have a single multi-mode laser having an ablating mode and a measuring mode and a positioning means for positioning the laser between ablating and measuring modes.  According to the method of the invention, the profilometer laser measures the thickness of a diamond sample and compares it to the desired thickness.  Where the measured thickness is too large, the feedback control unit activates the ablating laser for a predetermined time interval to smoothen any irregularities which may be contributing to the diamond sample thickness.  At the end of the time interval, the portion is remeasured by the profilometer laser to determine if it conforms to the desired thickness.  If the portion still fails to conform to the desired thickness, the feedback control unit repeats the steps of positioning and activating the ablation laser to further ablate the portion. This process is repeated until the thickness of the portion is equal or less than the desired thickness, after which the same procedure is used on the rest of the diamond sample until a uniform desired thickness is achieved throughout.

Patent CA-2168324-A1 (CA)
Title: Transmission method and transmitter for signals with a decoupled low level and at least one coupled high level, interface circuit and system component for a telecommunication network including such a transmitter
Inventor: LOUAGIE FILIP MARCEL
IPC: H04L25/02
Filed: 1996-01-29
Abstract: To go from a coupled  high level to the decoupled low level, the source unit (SU) of the transmitter (T) must be decoupled from the transmission line (TL) by the impedance unit  (IU).  As a result,  oscillatory transition phenomena appear in the output signal and this signal possibly goes beyond a prescribed template.          To  avoid  such  overshoot  problems  the  present transmitter (T) decreases the signal level during a decrease period  before decoupling  the  source  unit  (SU)  from  the transmission line (TL).          Therefore  a  source  control  circuit  (SCC)  is included in the control unit (CU) of the transmitter (T). This source control circuit (SCC) enables controlling the source level in such a way that the output signal level is decreasing.
Patent CA-2169577-A1 (CA)
Title: Apparatus for processing plastic sheet
Inventor: KJELDSEN PETER
IPC: B29C35/16
Filed: 1996-02-15
Abstract: The usual practice when molding thermoplastic sheets is to form the sheets in a closed mold and leave the sheets in the mold until the sheets have cured sufficiently for removal and further processing or shipping.  The sheet cooling or curing step is the longest step in the molding operation.  In order to speed up the process, it is advantageous to remove the plastic sheet from the mold for cooling the sheet at a location separate from the mold.  The present invention provides a simple sheet cooling apparatus, which is similar to a mold, including a lower cooling clamp fixed in a frame, and an upper cooling clamp movably mounted in the frame for movement between an open position in which the clamps are spaced apart for receiving a plastic sheet, and a closed position in which the sheet is sandwiched between the upper and lower clamps.  Water is continuously circulated through a manifold at one end of the clamps into both of the clamps and is discharged via second manifold at the other end of the clamps for cooling the sheet while a second sheet is being molded.  The invention also provides a transfer mechanism for simultaneously removing a first sheet from the mold and a second sheet from the cooling clamp for further processing or shipping.

Title: Single-motor setting and printing postage meter
Inventor: FLUECKIGER DANIEL
IPC: G07B17/00
Filed: 1996-04-11
Abstract: A self-contained postage meter does not have a base separable from a main body.  The single secure housing contains everything that would be in the main body of a prior art postage meter and everything that would be in a prior art meter base.  Despite containing all these things, the single secure housing is small enough and light enough in weight to permit the entire meter to be readily transported to the post office for inspection or resetting.  Within the single secure housing are the print rotor with value wheels, all the mechanisms for setting the print wheels, the descending and/or ascending register and associated microprocessor, and all the mechanisms for transport of the mail piece through the meter.  Only a handful of controlled elements are required, chiefly a single inexpensive DC motor for franking and value wheel setting and a few electromagnets.  Two one-way clutches are used so that rotation of the motor in one direction accomplishes a setting cycle for the value wheels and rotation of the motor in the other direction accomplishes a printing (franking) cycle.  The setting cycle uses a four-bar linkage to rotate a setting axle in one direction and in the other direction.  Clutches on the setting axle permit selective transmission of setting movement to the value wheels, mediated by pawls which are controlled by electromagnets.  Power consumption is small and the meter is reliable.  Despite the relatively low bulk and parts count the design satisfies simultaneously the demands of the postal authorities and the needs of the users.

Inventor: RIVETTE STEPHEN
IPC: B08B9/08
Filed: 1996-06-25
Abstract: A system for cleaning totes is disclosed in which each tote has a fill opening at its top and a dispensing valve, both of which are open to an interior chamber of the tote. The system includes a conveyor line having a receiving end and a discharge end and which is adapted to transport the totes from the receiving and to the discharge end. At a first station along the conveyor, the tote is initially drained of any remaining fluid within its interior and the tote is then moved to a second station. At the second station, a wash solution is cycled through the tote in order to clean the interior of the tote. The wash solution is recycled and appropriate fillers are used to remove the impurities from the wash solution. The tote then progressively moves through three rinse stations along the conveyor line in which each rinse station includes a lid attachable to the fill opening of the tote and which progressively rinses the interior of the tote. Thereafter, a dry station forces heated and filtered air through the interior of the tote thus completely drying the entire interior of the tote. Thereafter, a cleaned lid for the tote is replaced onto the fill opening together with the cleaned valve assembly and the now clean tote exits from the discharge end of the conveyor line.

Filed: 1995-02-03
Abstract: An anhydrous cheese-based prod-uct is provided which may be made into a cheese-based dry flake for incorpo-ration into baked goods anf flour con-fections, or which may be used in the preparation of snack items. The cheese-based product comprises from substan-tially 0 to 2 % by weight of mois-ture, from about 20 % to about 50 % by weight of cheese solids, with the balance being cheese-compatible oils. The cheese solids are naturally occur-ing cheese solids that are derived from cheeses from which substantially all wa-ter has been removed, and thereby com-prise the butterfat, protein, and lactose constituents of cheese. The cheese-comptatible and bakery-compatible oils must be selected from the group consist-ing of suitable vegetable oils, butter oils, or other dairy fats, and mixtures thereof, which exhibit generally similar solid fat index and melting point characteristics as those of butterfat; and they must be miscible with the butterfat constituent of cheese solids, in any proportion, at tem-peratures of about 35 °C to about 40 °C, so that to make a substantially homoge-nous mixture therewith, and in which the protein and lactose constituents are held in suspension.  In manufacture, the ingredients are mixed so that the solids are suspended in the oils, and oil crystallisation is initiated in a tempering unit. Then, the tempered product is passed through a cooling tunnel to cool and crystallize the fats.
