Title: Discharge lamp dimmer
Inventor: SCHILLER URI
IPC: F21V23/00
Filed: 1994-04-19
Abstract: ABSTRACT   A novel dimming assembly for controlling light intensity of a gas discharge lamp, including:     dimming controller having an input terminal connectable to one pole of an alternating current source and having an output terminal connectable to the line leading to one of the two filament electrodes of the lamp, the dimming controller being adapted to provide an attenuated and conditioned power at its output terminal; the dimming controller being adapted upon feeding the input terminal with the current, to operate in full power mode for a time period t1, during which the link between the two terminals is in full conductance bringing about full light intensity of the discharge lamp, and being further adapted after t1 to enter into a dimming mode, during which the link between the two terminals is in partial conductance bringing about attenuated intensity of the discharge lamp; the said time t1 is sufficient to facilitate effective dimming in the dimming mode. By another embodiment the dimming controller is adapted upon feeding the input terminal with the current, to gradually switching, for a period t2, into dimming mode in which the link between the two terminals is in partial conductance bringing about attenuated intensity of the discharge lamp, the time delay t2 is sufficient for facilitating effective dimming.

Title: Polarizerless magneto-optic speed and torque sensor
Inventor: RUDD ROBERT E
IPC: G01P3/488
Filed: 1992-11-30
Abstract: A polarizerless optic sensor is provided that uses a random domain magneto-optic film and a modulated normal magnetic field to vary or modulate the energy distribution in a diffraction pattern.  Light is transmitted through the film and is diffracted according to a domain duty cycle so that the center beam intensity is a function of the Faraday rotation angle of the material and the intensity of the applied normal magnetic field. The polarizerless sensor can be used to realize a speed and torque sensor, an optical switch, a magnetic field sensor and many other types of devices. The invention can be used with polarized and unpolar-ized input light. The sensor can be implemented using a random domain film or a stripe domain film to create a phase grating diffraction pattern.

Title: Control Apparatus for Power Converter
Inventor: IKEDA KATSUMI
IPC: H02M1/42
Filed: 1994-07-06
Abstract: The input voltage VR is detected by means of a voltage detecting device and the phase .PHI. of the input voltage is detected by means of a phase synchronizing circuit.  The detected phase is input to an AC sine wave reference oscillating circuit in order to obtain an AC sine wave reference signal having the same phase as input voltage.  The output of an amplitude instruction generating circuit is multiplied by an AC sine wave reference signal by means of a multiplier in order to obtain a converter current instruction IA*.  On the other hand, the input current IR detected by means of a current detecting device is differentiated by means of an approximation differentiator and only the resonance frequency component is detected by means of a band-pass filter.  The detected resonance frequency component is multiplied by the gain K by means of a proportion device and the output is subtracted from the converter current instruction IA*  by means of a subtracter.  The current control amplifier and PWM modulating circuit control a converter so as to make the output from the subtracter agree with the converter current IA*  detected by a current detecting device.

Inventor: CALDWELL FRANK J
IPC: B01F35/60
Filed: 1994-07-28
Abstract: A food mixer is provided with a bowl guard consisting of a fixed first semi-cylindrical splash guard portion and a removable semi-cylindrical second see-through portion pivotable about a cylindrical mixer transmission. The second portion is suspended from the transmission by spaced guide shoes mounted on a circumferential ring at the upper end of the pivotable portion. The shoes slidingly engage a fixed track extending horizontally and circumferentially around the transmission portion. The improvement consists of the track being provided as an essentially continuous bead formed in a cylindrical sheet metal band covering the transmission portion. The bead is integral with the band and may be created by rolling or spinning it into the band with metal forming tools. When the second portion of the bowl guard is removed for cleaning away from the mixer, the exterior of the band can be easily cleaned by wiping, since its method of manufacture provides a band surface which is essentially free of food-collecting crevices.

Title: Gas cylinder lifting system
Inventor: MATUS TIM A
IPC: B23K9/32
Filed: 1994-12-15
Abstract: A gas cylinder lifting system is useful for loading and unloading heavy tanks of gases onto and off of a welding power supply running gear. The gas cylinder lifting system comprises one or more sliders that are constrained for vertical reciprocation on a frame mounted to the running gear.  The slider includes a pan for supporting a gas cylinder.  A crank lever is pivotally mounted to the frame by a pivot pin, and a linkage is pivotally connected between the crank lever and the slider.  The linkage has a crook in it.  Pivoting the crank lever to a first angular position lowers a slider and places the linkage crook remote from the pivot pin.  Rotating the crank lever to a second angular position raises the slider and places the linkage crook adjacent the pivot pin.  The crank lever and linkage cooperate to place the gas cylinder lifting system in an over-center self-locked condition when the crank lever is in its second angular position.  A spring-loaded latch may be installed on the frame that positively maintains the crank lever at its second angular position but that is manually operable to enable the crank lever to rotate to its first angular position.

Patent CA-2141223-A1 (CA)
Inventor: ERICKSON BART J
IPC: G01S1/04
Filed: 1995-01-27
Abstract: A multilateration location system (12) includes a locatable unit (16) and any number of known-position locators (14). A time of arrival detector (22) determines instants in time when a location signal (20) transmitted by the locatable unit (16) arrives at various known-position locators (14). For each combination of two known-position locators (14) that receive the location signal (20), a pre-estimation process (32) determines whether the difference in arrival times is less than or equal to a maximum propagation duration for the locator pair. The maximum propagation duration is based upon the distance between the locators (14) in the locator pair. If the difference is greater than the maximum propagation duration, the difference is omitted from the data set processed by a multilateration calculation process (34). A post estimation filtering process (36) screens out location estimates that are too distant from a predicted position.
