Packaging apparatus and method for inserting food articles into a bag of comparable size. The apparatus has a conveyor that orients the product along a longitudinal axis and delivers the food article to a tray disposed below the conveyor so the product drops from the conveyor and onto the tray. The tray and conveyor move at speeds selected so the product maintains its longitudinal orientation as it drops from the conveyor into the product tray. A bag scoop holds the bag mouth open while the tray carrying the product advances into the bag. A product stripper moves into a position behind the bagged product after passage of the tray so that when the tray returns to its start position, the stripper butts against the end of the product and holds the product while the tray slides out of the bag.

The present invention is an electronic circuit that significantly enhances timing margin in high-speed, digital memory modules. The circuit is implemented is applicable to all switching waveforms on both control and data signal lines that drive the memory bus. Implementation of the present invention also provides a significant reduction in power dissipation compared to memory modules of comparable size and speed utilizing the present art.

An electrical ionizer comprising a fan (5) for producing a laminar flow of air; a positive ion emitter (6b) for ejecting positive ions into the flow of air; a negative ion emitter (6a) for ejecting negative ions into the flow of air; a positive voltage supply (27) to the positive ion emitter; a negative voltage supply (28) to the negative ion emitter; and a microprocessor (30) for controlling the positive and negative voltages to obtain a desired ion balance in the flow of air. The fan (5) is a crossflow fan, resulting in a highly uniform and laminar beam of air along the entire length of the fan, with reduced gaps in the air flow and consistent velocity of air, improving ion balance. The use of a crossflow fan also enables the operating mechanism to be contained within a simple 'teardrop' profile, and for operative parts of the device, for example the motor, the bearings, and electronics such as printed circuit boards to be housed outside the air flow, thereby eliminating a possible source of contamination of the air flow. For a comparable size of ionizer enclosure, approximately twice the mass flow, at higher velocities, can be generated as a similar conventional device using axial fans, and at reduced noise levels.
