Abstract: A motor controller that outputs a drive signal to a direct-current brush motor to drive the motor is provided. The motor controller includes a drive signal generating section that generates the drive signal. The drive signal generating section generates the drive signal by superimposing on a direct-current voltage a compensation voltage for generating a compensation torque that can cancel rotation torque fluctuations in a no-load rotation state of the motor.

Abstract: Substrates (100) are described for receiving a plurality of samples, especially for the preservation of biological samples at cryotemperatures comprising a plurality of substrate plates (11, 12, 13) arranged on top of one another as a stack (10) and comprising an anchoring axis (20) to which the substrate plates (11, 12, 13) are connected. Processes for the preservation of biological samples at cryotemperatures are also described.

Abstract: A labeling apparatus and method for continuously applying a layer of a radiation curable adhesives to plastic, sheet fed, cut and stack, labels, irradiating the adhesive on the labels, prior to and/or subsequent to adhering the labels to containers, e.g., a bottle, to render the adhesive sufficiently tacky to effectively permanently seal the labels to containers in a commercial labeling machine. The plastic labels can be clear, opaque (including metallized) plastic films and can be retained in a dispensing magazine prior to the application of the radiation curable adhesive to the labels.

Abstract: An electrode comprises an outer tube containing a spiral inner electrode which surrounds a rod held at its ends by fittings in the ends of the tube.

Abstract: An air conditioning unit comprises at least a fan, a circuit containing water, a condensation collection unit and an air filter together with process logic means to monitor the speed of rotation of the rotary fan to sense the condition of the other components and to activate an alarm in the event that the condition of any one component deviates from a predetermined status.

Abstract: A hermetic package for fine particulate material. The package is arranged to be filled and vacuumized to hold the fine particulate material therein and isolated from the ambient atmosphere. The package, which may be in the form of a pouch or a gussetted packages, is formed of a flexible material to have at least a front and a rear panel. At least one degassing valve is mounted in at least one of the panels to enable gas within the interior of the package to vent to the ambient atmosphere. A filter sheet, e.g., a spun-bonded plastic, such as Tyvek.RTM., is secured to the interior of the package over the valve to prevent the fine particulate material within the package from entering into the valve and clogging it. The filter sheet may cover only a small portion of one of the panels of the package or may cover a major portion of that panel, or even cover substantially the entire interior of the package. The package includes a top portion forming a mouth, which is arranged to be opened, e.g.

Abstract: A rotational molding apparatus that utilizes stationary temperature sensors, e.g., infra-red thermometry (IRT) sensors, for continuously monitoring the temperature of the molds during rotation.

Abstract: A fashion sleeve to be worn by a person, the fashion sleeve comprising a hollow tubular cloth or woven member having a wider upper opening and a narrower wrist opening, with the sleeve being tapered from the upper arm opening to the wrist opening and the upper opening having means to engage snugly the arm of the person.

Abstract: The combination of a dispenser and a strip of a food product and a method for dispensing the food product from the dispenser so that it can be used by a user of the dispenser. The strip comprises an elongated web of an edible material, e.g., gum, which is coiled up in a compact configuration having a free end portion. The dispenser comprises a housing for the strip, an outlet, a motor for advancing a desired length and most preferably any desired length of the free end portion of the strip out of the outlet, and a severing element for severing the desired length of the free end portion of the strip from the remaining portion of the strip to form a dispensed section of the strip which may be placed in the user's mouth while the remaining portion of the strip remains within the housing.

Abstract: A storage rack mounting device for releasably storing a plurality of tape storage compartments or modules therein. The storage compartments are utilized to hold a plurality of tapes, sch as computer tapes, therein. The rack includes a frame to hold a plurality of tape storage compartments and comprises two opposed sidewalls spaced apart to receive the tape storage compartments therebetween. Upper and lower mounting flanges extend outwardly from the interiors of each of the sidewalls to hold therebetween the tape storage compartment and to permit the tape storage compartment to be introduced and removed from the frame. The storage compartments have two sidewalls, at least one of which has an opening therethrough and a peripheral edge thereabout to releasably engage a locking flange which extends rearwardly and outwardly at an angle from the interior of the sidewall.

Abstract: A coffee filter dispensing and storage device which is compact, and inexpensive to manufacture. The device comprises a housing having a hollow interior in which a stack of coffee filters are located, and a cover pivotally mounted thereon. The cover includes a simple biased plunger mechanism with a wax or putty-like adherent at one end to extract the top most of a nested stack of coffee filters stored in a device. The device may be placed on a counter or table top or mounted on a wall or beneath a shelf or counter. Restraining tabs are used to prevent the filters from falling or spilling out of the device when the cover is opened. A locking mechanism is provided to hold the cover closed.
