Patent CA-2283012-A1 (CA)
Inventor: KIM CHEOL-JIN
IPC: H05B6/68
Filed: 1999-09-22
Abstract: In the microwave oven having a high voltage driving part with a high voltage transformer, a switching unit applies electric power to the high voltage driving part. In the switching unit, when switched on, an operational contact firstly comes in contact with a first contact coupled with a PTC thermistor and secondly with a second contact after a given time period, and a driving unit generates driving force and turns on/off the switching unit. Since the switching unit and driving unit may be simply installed to effectively eliminate the inrush current, assembly and work efficiencies are improved according to a simpler wiring process, and also, the total manufacturing cost for the microwave oven is reduced.

Patent CA-2288592-A1 (CA)
Inventor: FRANK JEFF W
IPC: G01J5/04
Filed: 1999-11-08
Abstract: An infrared receiver mount is disclosed that is capable of directional reception with discrete positions and is applicable for use in a mobile carriage system. An infrared receiver is mounted within a conical section of an outer cover which directs the infrared receiver to receive infrared transmission from a first given angle of reception.      The outer cover contains a plurality of grooves, which are engageable with a plurality of tabs located on a base plate to prevent rotation of the infrared receiver. The tab and groove system provides a discrete number of directions for the infrared receiver to receive infrared transmission from a second angle of reception. While this second angle of reception is adjustable, the first angle of reception is predetermined. In one application, the infrared receiver is mounted to the lower portion of a carriage in order to receive light beams from an infrared transmitter. By disengaging the tabs from the grooves, the infrared receiver is rotatable to vary the second angle of reception. This locking mechanism can then be locked into one of a distinct number of directions. The locking mechanism provides more precise placement of the infrared receivers in an optimal receiving orientation and prevents unintentional movement of the infrared receiver from its desired reception position.

Title: Golf club shaft
Inventor: MCLELLAN WAYNE MAURICE
IPC: A63B53/10
Filed: 1999-11-16
Abstract: The "Cigar" shaft, (this is a Trademark), is an improvement of other golf club shafts because of the increase in diameter at a point where the golf club grip begins, and continues to the butt end of the shaft. This design enables standard golf club grips to be utilized without adversely affecting the swing weight or balance of the golf club. The "Cigar" shaft is larger in diameter than traditional shafts and is used for an alternate method of playing the game of golf. Other methods used to increase the diameter of a golf club grip would detrimentally affect the balance and swing weight of the golf club.

Inventor: GELDMACHER INGO M
IPC: G01V3/28
Filed: 2000-03-07
Abstract: A method of focusing the measurements from an array type induction logging tool using an inhomogeneous background rather than a homogeneous background.

IPC: B66F9/22
Filed: 1998-09-29
Abstract: A fork lift truck (100) includes a body (110), a drive mechanism (120) supported on the body for effecting movement of the body, and a fork carrying assembly (155, 170, 175, 180) carrying forks (150) which can be moved in height between a lowered position and desired raised positions. A tilt cylinder (200) is provided for tilting the forks through a fork tilt range. The truck further includes a pressure sensor (210) capable of generating signals indicative of the weight of a load on the forks, a fork tilt position sensor (250) capable of being activated when the forks are titled to extremes of the fork tilt range, and a controller (80). The controller is coupled to the drive mechanism, the pressure sensor and the fork tilt position sensor. It causes the drive mechanism to effect movement of the body up to a first maximum speed when at least one of the pressure sensor generates a signal indicative of a load on the forks having a weight above a predetermined value and the tilt position sensor is activated, and causes the drive mechanism to effect movement of the body up to a second maximum speed which is greater than the first maximum speed when the pressure sensor generates a signal indicative of no load or a load on the forks having a weight below the predetermined value and the tilt position sensor is inactivated. The lowering speed of the forks can also or alternatively be increased under the same operating conditions.

Title: Method and apparatus for retrofitting gas discharge lamp ballast for use with gas discharge lamp having different power rating
Inventor: FLORY ISAAC L IV
IPC: H05B41/18
Filed: 2000-04-19
Abstract: A method and apparatus are provided to retrofit a gas discharge lamp ballast designed for use with a first lamp having a first power rating to be used with a second lamp having a second power rating. The ballast has a core, a coil and a serially-connected ballast capacitance device and is characterized by a first net impedance of the ballast reactance to allow operation of the first lamp in an operating range in which the first lamp is designed to operate. When the first lamp is replaced with a second lamp having a different lamp impedance than the first lamp, the capacitance of the ballast capacitance device is selected so as to change the first net impedance of the ballast to a second net impedance which allows the ballast to maintain proper operating of the second lamp in accordance with its specifications and rating.

Patent CA-2310545-A1 (CA)
Title: Wireless communications using circuit-oriented and packet-oriented frame selection/distribution functions
Inventor: BERLINER EDWARD FREDERICK
IPC: H04W16/02
Filed: 2000-06-02
Abstract: In a wireless communications system having a centralized interworking function (IWF) and geographically distributed base stations, a packet-oriented frame selection/distribution (FSD) function forwards forward-link user data intended for a particular mobile unit directly to a primary base station, which determines whether to transmit the forward user data to the mobile unit using a fundamental channel or a supplemental channel. If the data is to be transmitted using a fundamental channel, when the base station is operating in soft handoff, the forward user data is transmitted from the primary base station back to a circuit-oriented FSD  function for forwarding to all of the base stations currently participating in the soft handoff, so that all of the base stations can transmit the forward-link user data to the mobile unit at the same time. If the data is to be transmitted using a supplemental channel, then the primary base station is able to assign a supplemental channel and transmit the forward user data to the mobile unit using the supplemental channel in simplex mode, independent of whether or not the mobile unit is otherwise operating in soft handoff. In this way, forward-link data transmissions can be performed without first having to coordinate either the timing or the data rate with any other base stations or with the FSD function. As such, the reactivation time needed to resume active forward-link data transmissions using a supplemental channel from the control hold state is less than the corresponding reactivation time under the prior art, which does require coordination of timing and data rate between all base stations in soft handoff.

Title: Partially densified carbon preform
Inventor: CONNORS DONALD F JR
IPC: F16D69/02
Filed: 1999-01-14
Abstract: The invention includes a partially densified preform and a method for the densification of one or more porous preforms. The porous preform is heated in the precursor liquid at a temperature sufficient to decompose the precursor liquid and to deposit a first decomposition product of the precursor liquid within the preform. Heating of the preform is ceased in the precursor liquid prior to densifying to the surfaces of the preform, thereby forming a partially densified preform. The densification is completed by chemical vapor deposition in an atmosphere comprising a gaseous precursor that heat decomposes to a second decomposition product within the undensified portions of the preform. The partially densified preform includes a densified region within the preform. The densified region includes a deposited decomposition product of a precursor liquid decomposed by liquid densification. An undensified region of the preform is between the densified region and at least one surface of the preform.
