Abstract: An audio device with a body configured to be worn on or abutting an outer ear of a user, wherein the body is configured to contact at least one of the outer ear and the portion of the head that abuts the outer ear, at two separate spaced contact locations, and wherein the body is compliant at a body portion that defines one of the contact locations. The device also has an acoustic module carried by the body and configured to locate a sound-emitting opening anteriorly of and proximate the user's ear canal opening when the body is worn on or abutting the ear of the user.

Abstract: An automatic form dispensing system for a variety of transactions has a housing with an operator interface for receiving operator input, and has a form dispensing assembly in the housing and a roll of blank form stock and two rolls of a carrier web containing blank stickers retained thereon by a pressure sensitive adhesive. At least one of the stickers is removed automatically from the carrier web and applied to the blank form stock as the blank form stock moves towards a dispense slot of the housing. A printer thermally prints information on the sticker and on a portion of the blank form stock adjacent the applied sticker in response to the operator input. A cutter cuts the printed potion of the form stock which contains the applied sticker from the roll of blank form stock to provide a completed printed form. A dispensing device then dispenses the printed form from the housing through a dispense slot.

Abstract: An opened front refrigerated display case having multiple front refrigeration control air curtains and a supplemental refrigerated air curtain passing over the bin area thereof to aid in maintaining of the bin area of the display area of the case in an efficiently refrigerated condition and to minimize the accumulation of frost therein. The display case includes multiple inlets in the upper area above the opened front area and multiple outlets in the lower area below the opened front area to facilitate multiple curtains of controlled air passing thereover. The innermost lower inlet is adapted to also receive therein refrigerated air from a bin cooling air curtain which passes approximately horizontally over the bin area. Air is admitted into the curtain by a bin outlet positioned immediately adjacent to the main refrigeration flow duct path positioned immediately behind the bin area.

Abstract: A refrigerated food display case of the closed front type is provided with an improved means for inhibiting the formation of condensation on the front display window. To this end, the display case includes means dividing chilled air circulated within the case, into primary and secondary air curtains flowing across the display window. A heating means mounted only within the secondary air passage operates throughout each refrigeration cycle, to heat only the chilled air flowing within the secondary passage, thereby forming it into a secondary air curtain interposed between the window and the primary, fully chilled flow of air that has passed through the primary air passage and hence has not been exposed to the heating means. The warm air curtain, impinging upon the surface of the window, inhibits the formation of condensate thereon, such as commonly occurs due to the disparity of ambient temperature and the lower, interior case temperature.

Abstract: A wide island, open top refrigerated display case of the air defrost type has a vertical, hollow partition extending centrally and longitudinally of the case. The partition functions, during defrost cycles only, as an air passage through which the flow of defrost air is induced by operation of a defrost fan mounted in a hollow sill extending along the top of the partition. During refrigeration cycles, the fan is idle and there is no air flow within the partition, so that it forms a hollow dead air space operative to insulate from one another the product wells separated by the partition, a feature of particular importance when one well is refrigerated to a temperature different from the other. Various configurations are disclosed, in some of which the air is forced downwardly within the center flue or passage during defrost, while in others the air is drawn upwardly through the defrost passage.

Abstract: A refrigerated display case of the wide island type having side-by-side, upwardly opening product display wells, uses its primary air circulating fans and a defrost fan to draw ambient air into the inlet and outlet of the air conduit of one product well, circulate it through the conduit of that well, transfer it to the air conduit of the second well, circulate it through the second conduit, and discharge it to atmosphere through the inlet and outlet of the second conduit. The case incorporates a solid center partition having an opening near the bottom of the case in which the defrost fan is mounted to transfer the air from one product well to the other. A splitter panel and sill at the upper end of the partition prevent the intake air from becoming mixed with the exhausted air. During a defrost cycle the air can be drawn into the first well and exhausted from the second well for the full duration of the cycle.

Abstract: A damper system, for a reach-in refrigerated display case of the air-defrosted type utilizes a single gear-reduction, reversible motor to operate between open and closed positions a multiplicity of dampers, all of which must be operated simultaneously. A radial arm on the motor shaft has a pin-and-slot connection to one damper connected to a series of other dampers pivoted about a common axis for joint opening and closing thereof. Each of the connected dampers includes cam means acting upon tongues of a second series of dampers pivoted about a common axis parallel to the axis of the first damper series. When the dampers of the first series are actuated to open position, the cams individual to the dampers of that series act to cause corresponding dampers of the second series to open simultaneously therewith. In a similar fashion, all the dampers are closed simultaneously by reason of their interconnection and cam action.
