Patent CA-2277143-A1 (CA)
Title: Particles having surface properties and methods of making them
Inventor: GREY BRYAN DAVID
IPC: A61Q5/12
Filed: 1997-12-23
Abstract: Polymer particles comprising a hydrophobic organic matrix and located at the exterior free cationic groups and a further polymer which comprises free hydroxy groups. The particles are produced by an aqueous suspension polymerisation process wherein the continuous aqueous phase contains a polymerisation stabiliser and a dissolved vinyl addition cationic monomer. The polymerisation stabiliser can be any suitable polymer that comprises free hydroxy groups. The process results in polymers of average particle size in the range 50 to 150 microns and reduced levels of undesired polymer emulsion or undersized particles. The particles are particularly useful for absorbing water insoluble active ingredients, such as insecticides, insect repellents, fragrances, pheromones for subsequent slow release. The cationic surface character of said polymer particles makes them especially useful for forming stable dispersions or slurries in active concentrates such as perfume bases or detergent concentrates. Furthermore these dispersions or slurries remain stable and substantially free of agglomerates. The particles containing active ingredient readily associate with fabrics such as cotton, wool and viscose where the active ingredient is released in a controlled fashion over several days.

Patent CA-2289378-A1 (CA)
Inventor: SAUNER MARVIN H
IPC: B62D43/04
Filed: 1999-11-10
Abstract: A spare tire and wheel assembly for a motor vehicle are held in a stored position under the vehicle body by a compact tire lift unit or winch having a primary flexible cable extending to the center of a retaining bracket releasably attached to the wheel hub. A secondary or auxiliary cable has one end portion secured by a crimp connector to the winch cable spaced above the bracket and extends through a laterally offset hole within the bracket to receive a stop fitting spaced below the bracket. In the event the winch cable breaks adjacent the retaining bracket, the spare tire and wheel assembly drops slightly to an inclined position supported by the stop fitting where rattling of the tire against the vehicle body alerts the driver of the vehicle that the winch cable has broken.
Patent CA-2291118-A1 (CA)
Title: Clock regeneration circuit
Inventor: TADA SHUNICHI
IPC: H04J9/00
Filed: 1998-06-10
Abstract: A clock regeneration circuit for regenerating a clock signal for demodulating data from an AM data multiplex modulated signal where digitally modulated signals are multiplexed in the same frequency band as those of an amplitude-modulated signal at the same time. The carrier for an amplitude-modulated signal is extracted from an AM  data multiplex modulated signal where digitally modulated signals are multiplexed in the same frequency band as those of the amplitude-modulated signal at the same time through a band-pass filter (1), and the oscillation frequency of a voltage-controlled oscillator (5) is controlled by the output of a phase comparator (3) through a loop filter (4).  The oscillation output of the voltage-controlled oscillator (5) is supplied to a direct digital synthesizer (6) and the phase of the carrier extracted through the band-pass filter (1) is compared with the phase of the output of the direct digital synthesizer (6) by means of the phase comparator (3). The oscillation output of the voltage-controlled oscillator (5) is then synchronized with the carrier for the amplitude-modulated signal to produce a clock signal for demodulating data.
Patent CA-2294035-A1 (CA)
Title: Initialization of replicated data objects
Inventor: WIKSTROEM CLAES
IPC: G06F17/30
Filed: 1998-05-29
Abstract: In a replicated database environment, all nodes (30) monitor the well-being of each other by receipt of node status messages over a network (20). When a node is detected as no longer being alive, the other nodes deduce that such node has failed. When a node failure is detected, a node status record having a nodedown value is written into a node log (80) with respect to the failing node. Similarly, when a node comes alive or a new node becomes known to the network, a node status record having a nodeup value is written into the node log. When a local node fails and then is restarted, the local node uses the contents of its node log in order to determine how to initialize the value of a replicated data object. By reading its node log, the local node can decide whether the data object can be initialized from its disk (32) or not.

Title: Dust-collecting device for vacuum cleaner and upright type vacuum cleaner
Inventor: SAKATA SOUJI
IPC: A47L9/10
Filed: 2000-01-27
Abstract: A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.

Title: Method and apparatus for the detection of a reduction in capacity of a cdma system
Inventor: WING THOMAS E
IPC: H04B17/00
Filed: 2000-06-06
Abstract: A computer implemented method and apparatus for determining if a wireless telecommunication system is operating at a reduced capacity is provided. The method and apparatus utilize call processing information associated with every sector/carrier within a CDMA base station to determine if any sector/carrier is operating at a reduced capacity while also being limited by power control (i.e., power control is blocking new users from gaining access to the sector/carrier even though the sector/carrier is operating at a reduced capacity). Thus, the method and apparatus detect blocking faults effecting the capacity of the CDMA system.

Patent CA-2316339-A1 (CA)
Inventor: FALCK ROBERT W
IPC: A61B3/16
Filed: 1998-12-17
Abstract: An applanation tonometer with a replaceable prism for contacting a cornea has emitter and detector ports arranged opposite each other on opposite sides of a longitudinal axis, with the ports aimed at about 45° to the longitudinal axis. Light from an emitter then passes through the emitter port and crosses the prism axis to be incident and reflected from an emitter-reflecting surface of the prism and become incident on the applanation surface. Light reflected from the applanation surface is incident on and reflected from a detector-reflecting surface opposite and parallel with the emitter-reflecting surface to proceed across the prism axis to the detector port. Such an arrangement produces reliable applanation signals and varies the spacial intensity of light reflected from the applanation surface so that the tonometer can automatically distinguish between concentric and eccentric contact of the applanation surface with a cornea.
