Abstract: ABSTRACT           Method and apparatus for evaluating the quality of a flame in response to outputs from a flame sensor. The present invention includes a method and apparatus in which output pulses from a flame sensor are continuously counted.          The number of pulses is accumulated over a time interval of a predetermined length and compared with a threshold value.          The accumulated total is continuously updated to reflect the pulses received over the previous time interval to effectively provide a moving time-window of a fixed length over which pulses from the flame sensor are accumulated.  Other additional checks may be made to ascertain that a flame is present, including the time over which no pulses are detected and a long-term average of the number of pulses.  A preferred embodiment disclosed in which numerous self-checking features are incorporated, and which includes a novel bar-graph type of display for display-ing flame quality and diagnostic information.

Abstract: DRUM BRAKE HAVING DUO-MODE ABSTRACT OF THE DISCLOSURE A drum brake assembly includes a pair of brake shoes which are carried by a backing plate and engageable with a hydraulic actuator. The hydraulic actuator is operable to move the pair of brake shoes from a rest position to a braking position.  A strut extending between the pair of brake shoes cooperates with a parking arm to move the pair of brake shoes to the braking position during a parking brake application.  A support assembly on the backing plate is disposed opposite the hydraulic actuator for the purpose of absorbing braking torque developed by the pair of brake shoes.  The support assembly comprises a pair of slots and a lever.  The lever is movable in response to movement of the parking arm to adjust the position of the pair of blocks relative to each other.  In a first position the blocks are in abutment with the backing plate while in a second position the blocks are free to move a limited amount relative to the backing plate.  Moreover, the lever imparts a separating force to the pair of brake shoes via the blocks during a parking brake applica-tion to expand the brake shoes radially.  This expansion is in addition to the movement imparted to the brake shoes by the strut and parking arm.

Abstract: TITLE Serving Device ABSTRACT OF THE DISCLOSURE  A device for serving merchandise located in the interior of a building to a person located outside of the building is disclosed including first and second frames mounted in an aperture of the building and extending into the interior of the building.  A drawer is slidably mounted in the first frame from a first, open position extending out of the first frame to the exterior of the building and to a second, closed position located within the first frame.  A first door is pivotally mounted to the top of the first frame for closing the exterior open end of the first frame for movement from a first, horizontal position to a second, closed, vertical position substantially flush with the exterior of the building.  The first door is pivoted from its second position to its first position by moving the drawer from its second position to its first position.          A second door is pivotally mounted to the top of the second frame for closing the exterior open end of the second frame.          A slidable member pivotally attached to the second door and extending through the interior of the second frame allows the second door to be opened and closed from the interior of the building.  Thus, the first door in its first horizontal position is in a merchandise receiving position for receiving relatively flat merchandise passed through the second frame, and the serving device is substantially flush with the exterior of the building between customers and when not in use.

Abstract: ABSTRACT       The specification describes an improved cardiac pacer, and more particularly a pacer which is adapted for implantation in a patient.  The cardiac pacer apparatus has an electrode means including at least a first electrode adapted to stimulate the heart; control means including timing means which defines a sample time window and signal detector means including sensing means for sensing cardiac signals on the electrode means.  Filter means including a filter circuit receive the signal sensed by the sensing means for quantizing the sensed signal and continuously generating digital words representative of the slope of the sensed signal over the sample time window.  Parameter memory means store signals representative of predetermined selection criteria for defining at least one component of a cardiac cycle signal.          A selection circuit means including a selection circuit responsive to the quantized output signals of the filter means and the stored selection criteria signals generates a detection signal if the digital slope words meet the predetermined selection criteria.  Finally generator means generate a stimulating signal and couple the same to the electrode means if the selection circuit means fails to generate the detection signal within a predetermined time from a previous detection signal or a previous stimulating signal.

Abstract: ABSTRACT OF THE DISCLOSURE Electrostatic printing is disclosed in which an electrostatic latent image is formed on an imaging roller, toned, and transferred by pressure to plain paper.  Toner transfer efficiency is improved by providing a skew between the dielectric imaging roller and a pressure roller.  The latent image is formed by an ion generator consisting of two electrodes separated by a mica dielectric. The ion generator is fabricated by laminating a metal roll to mica using pressure sensitive adhesive, and etching the roll to form electrodes. An alternative ion generator consists of a dielectric-coated wire and a series of transverse conductors.  A preferred method of fabricating the dielectric roller involves anodizing an aluminum cylinder, and impregnating the surface pores with a metallic salt of a fatty acid while maintaining the pores in a substantially moisture-free state.     In photocopying, an electrostatic latent image is optically created on a precharged photoconductor and transferred to a dielectric member where it is developed with toner particles and the toner image is transferred to plain paper.     The apparatus for either printing or photocopying may be employed for duplex imaging with simultaneous pressure transfer and fusing of the toned images.
