Abstract: A scraper removes debris from under a work table, particularly slag resulting from cutting of metal. A pair of parallel tracks extends along opposite sides of a collection area under the table. A blade carriage is carried on the tracks and driven between forward and rearward positions. A pair of arm assemblies are connected to opposite sides of the blade and pivotally mounted to the carriage for moving the blade between a scraping position and a retracted position. A forward notch on each of the tracks is contacted by the arm assembly after reaching the forward position to cause the arm to move the blade from the scraping position to the retracted position during rearward movement. A rearward notch on each of the tracks is contacted by the arm assembly after reaching the rearward position and commencing forward movement to cause the arm to move the blade from the retracted position to the scraping position. The carriage is moved by continuous cables.

Abstract: A ventilation fan that functions as a wheel for movements. The generally cylindrical fan housing is pivotally coupled to a triangular handle. The handle may be manually grasped to roll the fan towards an operative position. The handle may be positioned in a temporary storage position, and an inverted, operative position where the drum is elevated for stable use. The drum-shaped fan rolls on its own, and the fan radius becomes the rolling radius. The preferred handle is attached to suitable bearings secured to the guards at the center of each side of the fan. When the destination is reached, the handle is deployed upside-down to function as a support stand, and the fan remains in a stable orientation without moving or shifting its position during operation.

Abstract: The invention is intended to improve reliability of a thermal type air flow measuring instrument employing a molded part formed by integral molding together with a metal plate. A slot or opening allowing only a resin to pass through the same is formed in the metal plate in an area or thereabout subjected to higher stresses. A part of connector terminals, which is not required from the intrinsic object, is disposed in the vicinity of a area where the resin has a larger thickness and the temperature difference between the inside and the outside of the resin is locally increased. An injecting direction is set so as to prevent a weld line and a void from being generated in a combined way. In the molded part with the metal plate inserted therein, the occurrence of cracks and an increase of the fatigue crack growth rate can be suppressed and reliability can be improved.

Abstract: A system for actuating a spray pump assembly comprises a reference platform, a motor, a drive transmission, a spray pump holder, a force coupler, a force transducer, and a system controller. The motor receives a power and control input, and produces a rotary drive output. The drive transmission receives the rotary drive output and produces a linear drive output. The spray pump holder secures the spray pump assembly. The force coupler couples the linear drive output to the spray pump, and applies a force to the spray pump. The force transducer produces a force signal proportional to the force applied to the spray pump. The system controller receives a set of test inputs and provides the control input to the motor as a function of the set of test inputs. The system actuates the spray pump mechanism according to an actuation profile defined by the set of test inputs.

Abstract: A composite reflecting surface for a linear LED array incorporates a truncated circular parabolic reflector surrounding each LED and a trough axially above the circular parabolic reflectors defined between parallel longitudinal reflecting surfaces. The short circular parabolic reflectors collimate wide angle light from the LED into a direction parallel to the LED optical axis. The longitudinal reflecting surfaces are linear parabolic surfaces altered to improve the vertical spread of the light radiation pattern. Longitudinal convex ribs project inwardly from the basic linear parabolic shape. The convex shape of the ribs “sprays” the light incident upon it in a vertically spread pattern. The composite reflecting surface makes use of light from a linear array of LEDs that would otherwise be wasted.

Abstract: Improved inductive apparatus having controlled core saturation which provides a desired inductance characteristic with low cost of manufacturing. In one embodiment, a pot core having a variable geometry gap is provided. The variable geometry gap allows for a “stepped” inductance profile with high inductance at low dc currents, and a lower inductance at higher dc currents, corresponding for example to the on-hook and off-hook states of a Caller ID function in a typical telecommunications line. In other embodiments, single- and multi-spool drum core devices are disclosed which use a controlled saturation element to allow for selectively controlled saturation of the core. Exemplary signal conditioning circuits (e.g., dynamically controlled low-capacitance DSL filters) using the aforementioned inductive devices are disclosed, as well as cost-efficient methods of manufacturing the inductive devices.
