Abstract: ABSTRACT             A merchandising display gondola for floor mounting has been provided with an upright frame and at least one forwardly extending bottom support frame that has a lower, floor hugging, horizontal positioning.  A pair of caster wheels are carried by a front end portion of the bottom frame, and a rounded, cross-extending, floor-engaging, tubular glide member is positioned adjacent a back end of the support frame.  The glide member with the front casters positions the structure in a stable, supported position on the floor and enables an easy, manual gliding type of movement of the structure, when loaded or unloaded, from one position to another.  The gondola is constructed of hollow, rounded tubular members of metal or reinforced plastic material for strength and weight saving purposes, and is provided with least at least one pegboard panel, whereby numerous types of shelf, hook, article-carrying or positioning elements may be used.  A colored masking design is applied to facing surfaces of the pegboard to screen its basic brownish or grayish drab, punchboard like appearance.  The panels are removably mounted in order that the display may, from time to time, be adapted to show different pictorial representations.

Granted: 1981-01-13
Abstract: 43.80 NON-CONTACTING GAGE APPARATUS AND METHOD The disclosure is directed to a technique for gaging the thickness of a material, typically an alloy of which a limited number of samples of known thickness are available.  An important aspect of the disclosure is the calibration of the gaging apparatus which is performed before the material measurement phase of operation.  Standard pieces of a known thickness and formed substantially of a "pure" metal which is the basic metal of the alloy material to be measured are irradiated with a radiation source.  A first set of measurement values detected as passing through the standard pieces is stored.  A first function is formed and stored which represents the relationship between the thickness of the standard pieces and the measurement values determined therefrom.  A second set of measurement values associated obtained with material samples of known thickness and having the same composition as the material to be measured is also stored.  Then, a second function which represents the relationship between the relative attenuation attributable to the standard pieces and the relative attenuation attributable to the material samples for different thicknesses thereof is also stored.  After an operator-entered nominal thickness for the material to be measured is stored, the expected measured value which would be obtained upon insertion of material of the nominal thickness in the inspection field is computed from the operator-entered nominal thickness in conjunction with the first function and the second function.  The source and/or detector is then adjusted in accordance with the determined expected measured value.

Abstract: ABSTRACT OF THE DISCLOSURE         The cardiac pacer disclosed herein responds to a pre-mature heartbeat by first digitally measuring the time interval between a pair of successive sensed heartbeats and establishing an escape interval for stimulation which is shorter than the measured heartbeat interval.  Pacing at this shorter escape interval enables the pacer to capture and control the heartbeat rate.  By repeatedly incrementing the digital value representing the escape value on successive stimulated heartbeats, the heart is then caused to slow down until a preselected desired rate is established.  Preferably, the sensing and timing between heart-beats continues during the slowdown process so that,if, at any time, a natural heartbeat occurs earlier than the stimulation pulse at the then extant escape interval, the escape interval is reset to a shorter time so that capture will be re-established.

Abstract: ABSTRACT         A ring trip circuit adapted for use in a community office switching system that includes a call control processor and a port event processor.  The call control processor and port event processor interact through a port storage unit that contains information corresponding to each telephone line con-nected to the switching system.  The switching system also in-cludes a ringing generator for transmitting ringing signals onto a telephone line to a called party.  Windings for a common bridge relay connect in circuit with each telephone line and diodes shunt the windings so the relay responds only to signals of one polarity. The contacts of the common bridge relay, therefore, reflect the duty cycle of the signal through the common bridge relay and this duty cycle varies when the called party goes off hook during a ringing burst.  The common bridge relay produces a supervisory signal that is sampled and trans-ferred, for each telephone line, to a corresponding port stor-age area.  A single ring trip analyzer sequentially monitors each port storage means during a ringing operation to determine whether the supervisory signal indicates that the called in-strument has been taken off hook.  When this occurs, the ana-lyzer updates control information in a corresponding port stor-age area to control the state of a ring relay.  The ring relay then opens and removes the ringing signal from the correspond-ing telephone line.  The analyzer also detects offhook status during intervals between successive ringing bursts and during normal operations when a subscriber lifts a telephone off hook in order to place a call.
