Patent CA-2195085-A1 (CA)
Inventor: SCHAUDER COLIN D
IPC: H02J3/18
Filed: 1995-06-13
Abstract: A transmission line power controller (50) for controlling the flow of electric power in an alternating current three-phase transmission system (34) is described. The power line controller (50) includes a parallel inverter (22) connected to a series inverter (24) through a dc link (26). The parallel inverter (22) is connected in shunt to the transmission system (34) through a shunt transformer (36). The series inverter (24) is connected in series with the transmission system through a series transformer (38). A transmission line power control circuit (52) is used to specify a desired real power demand and reactive power demand for the transmission system (34). The power control circuit (52) processes this information along with a transmission line voltage vector and a transmission line current vector to produce a voltage source reference signal that is applied to the series inverter (24). In response to the voltage source reference signal, the series inverter (24) produces an injected voltage vector into the transmission system (34). The injected voltage vector forces the transmission line current vector to a desired value corresponding to the specified real power and reactive power demand. Thus, desired real power and reactive power flow is rapidly achieved on the transmission system (34).

Title: Cable partial discharge location pointer
Inventor: DU ZHIFANG
IPC: G01R31/08
Filed: 1995-12-22
Abstract: A method and apparatus for detecting the location of an incipient fault in an insulated power system which includes the application of an excitation voltage to a power line to produce a partial discharge signal pulse at a fault along the power line. The surface of the power line is scanned with two axially spaced sensors disposed adjacent the surface of the power line, the sensors detecting the partial discharge signal pulse to produce discrete detected pulses. These detected pulses are combined to produce a combined signal having an amplitude level which reaches an extreme value when the fault is located equidistantly between the sensors. The sensors are moved along the power line until the fault is located substantially equidistantly between the sensors as indicated by the extreme amplitude level of the combined signal.

Title: Pll circuit of display monitor
Inventor: HIRAKAWA HARUYASU
IPC: H03L7/08
Filed: 1997-07-25
Abstract: In a PLL circuit used in a display monitor, it is made possible to design a PLL circuit using a VCO of excellent frequency stability. In this PLL circuit, low jitter of display monitor is realized without having to consider variations of oscillation frequency of VCO practically. It solves the problems of effects of variations of oscillation frequency on the cost and productivity.  This PLL circuit preliminarily detects the range of frequency divid-ing range of the frequency dividing ratio of the dividing circuit capable of locking the PLL circuit with respect to the input signal with known frequency by frequency detecting means. The detected frequency data is stored in the memory. On the basis of the frequency data, the frequency dividing ratio of the dividing circuit is set. By this setting, even if different input signals are entered, the VCO operates at a frequency near the center of the variable range of the oscillation frequency.

IPC: H01K3/06
Filed: 1996-01-24
Abstract: An electric incandescent lamp is disclosed, in particular a low-watt, lowvoltage incandescent lamp, as well as a process for producing the same. The lamp has a helical tungsten filament (4) with straight ends (4a, 4b) that are each soldered or welded to a current supply (2, 3). The current supplies (2, 3) are made of a metal with a lower fusion temperature than tungsten. In order to solder or weld the incandescent helical filament (4) to the current supplies (2, 3), the latter are arranged in such a way that the straight ends (4a, 4b) of the helical filament and the preferably hook-shaped ends (2a, 3a) of the current supplies cross each other. The ends (2a, 3a) of the current supplies are quickly heated up to their fusion temperature by a laser. The molten mass flows over the corresponding end (4a, 4b) of the helical filament, so that after the molten mass solidifies the ends of the helical filament are embedded in the metal of the current supplies.

Abstract: Apparatus and methods for uniformly twisting hollow, open-seam rods with preferably rectangular cross-sections for use as decorative curtain rods are disclosed.  The twist extends throughout substantially the entire length of the rod.  This feature enables a telescoped pair of rods, that is, a pair of rods with an inner rod dimensioned to slide into and out of an outer rod, to be twisted simultaneously such that the telescoping feature is maintained after twisting.  The apparatus includes a rotatable first chuck and a substantially non-rotatable second chuck.  Each chuck has male and female components to engage the inner and outer surfaces of a respective end of the rod.  These components prevent buckling along the open seam and permit twisting throughout substantially the entire length of the rods.  Sensor controls ensure uniform twisting and controlled unwinding of the rods.  The controls are programmable to vary the amount of twist performed on each rod, and the apparatus is adjustable to accommodate rods of different lengths.  In addition, rods with other cross-sections can be twisted.

Abstract: A package for a solid stick product, including barrel (10) for containing the stick product and, provided within the barrel, a product support member (16) for supporting the stick product thereon. The product support member (16) is movable in the longitudinal direction of the barrel for raising and lowering the stick product. The barrel has a longitudinally extending slot (34) through a wall thereof. An adjustment button (28) is provided on the outside of the barrel and is movable in the longitudinal direction of the barrel generally over the slot area. A tab (30) extends through the slot (34) and connects the adjustment button (28) to the product support member (16), whereby movement of the adjustment button outside the barrel brings about equivalent translational movement of the product support member and, therefore, the stick product within the barrel. Thus, by raising or lowering the adjustment button (28) outside the barrel, the user can raise or lower the stick product to extract the product from or retract the product within the barrel. The package includes a locking mechanism (36) for locking the product support member and preventing movement of the product support member in the longitudinal direction.
