Abstract: 1                     PHP. 1236 ABSTRACT:             A dual beam ratio recording spectrophotometer has signal processing circuitry for determining the transmittance of a substance.  The signal processing circuitry has a bandwidth which is dependent on the magnitude of the radiation passing through a reference cell and includes control logic circuitry which pro-duces a pulse on line m whose width is proportional to the square of the magnitude of the radiation detected when the beam passes through the reference cell.  A sample and hold circuit whose sample time is controlled by the pulse on line m samples the output of an inte-grator which produces at regular intervals a signal representative of the transmittance of a substance. Thus the response time of the sample and hold circuit and hence the bandwidth of the signal processing cir-cuitry depends on the magnitude of the radiation pass-ing through the reference cell.

Abstract: An extendable table has a legged base defining a horizontal support surface extending in longitudinal and transverse directions and having a pair of outer transversely extending edges, a first table panel resting on the support surface and having a transversely extending inner edge intermediate and generally parallel to the outer edges, and a second table panel restable on the support surface, having a transversely extending inner edge buttable with the inner edge of the first panel, and formed with a pair of transversely open and longitudinally extending grooves. Respective rollers on the base underneath the second panel define a transversely extending first pivot axis, and extend transversely into guiding engagement with the grooves. Thus the second panel can slide longitudinally relative to the base on the rollers and can be pivoted on the rollers about the first pivot axis. A pair of parallel links each have one end pivoted about a second transverse axis on the base and generally parallel to the first transverse axis and another end pivoted on the second panel about another transverse axis. Thus the second panel can move with simultaneous pivoting about the first axis and sliding perpendicular thereto between an inner position with its inner edge butting the inner edge of the first panel and an outer position with its inner edge spaced from the inner edge of the first panel. A leaf is engageable in the outer position of the second panel between the inner edges.

Abstract: ANTI-KICKBACK POWER TOOL CONTROL                 ABSTRACT OF THE DISCLOSURE    An impending kickback condition in the operation of a power tool or machine tool system is sensed and used to con-trol or eliminate the kickback.  The ability to sense an impending kickback condition can be used in all categories of power driven tools.  The change in force applied to the power driven tool or other implement is monitored with a microcomputer by measuring the rate of change of current.          If the current is increasing, the microcomputer compares the rate of change of current with a threshold value which may be either preset or computed by the microcomputer.  If this threshold value is exceeded, an output control signal is generated by the microcomputer which inhibits the coupling of power to the tool or other implement and/or applies a brake to stop the tool or implement.  In order for power to once again be coupled to the tool or implement, the start switch must be opened and then reclosed or some other signal provided by the operator or another predetermined condition must be fulfilled.

Abstract: Wheelchair Lift Abstract A lift device particularly suitable for hoisting handicapped persons with or without wheelchairs into a vehicle. The lift can be installed into the door well of a public transit bus or of a railroad car. It could also be incorporated into a step structure inside a building. The lift platform (72) is made of four hinged, parallel sections (2,3,5) which in the stowed position of the lift fold back to form two steps (A,B). The first parallel section (2) which in the uppermost position of the platform meets the vehicle floor (F), or the upper step landing in a building, rotates along its forward edge to form the back of the upper step (B) in the stowed position. The second section (3) becomes the tread of the upper step (B) while the third section (4) forms the riser between the upper and lower steps. The fourth section (5) which forms the tread of the lower step (A), houses an access ramp along its forward edge and a retractable flap (15) which rotates upward to form an angled stop preventing the wheelchair from rolling back off the platform during motion of the lift. The load-carrying platform is supported by a moving carriage connected to the infrastructure of the lift by a linkage assembly featuring plastic bearing blocks slidingly engaged into vertical channels. In addition to its vertical lifting movement the platform can be tilted downward from its normally horizontal position in order to accommodate slight differences in elevation between the ground and landing surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE            We have discovered that certain photoluminescent minerals of zinc, fluorine, tungsten, molybdenum, mercury and other elements which may naturally occur at the surface of the earth can be selectively detected in the presence of most other photoluminescent minerals and organic materials which are likely to occur at the earth's surface.  The basis of selective detection is the discovery that the lifetimes of photoluminescent emission of materials in the latter class are much shorter than the lifetimes of photoluminescent emission of materials in the former class.  This invention utilizes this discovery in the detection of minerals of uranium, zinc, lead, fluorine, tungsten, molybdenum, mercury and other elements.  In one embodiment of the invention, using a laser or other short duration source of optical excitation, measurements of the photoluminescent response of the earth are made at times sufficiently long for the photoluminescence of other common and unwanted sources to have substantially decayed, thereby selectively detecting and identifying certain minerals of potential economic interest.  In another embodiment a source of light is modulated at a predetermined frequency and the photoluminescent response of the earth which is out-of-phase with the source is measured.  In a third embodiment this source of light may be incident solar radiation after passage through a suitable modulator.

Abstract: Docket D-2076     GRAVITY FEED SHELF                      ABSTRACT A gravity feed shelf for use as a component of a display device for primary packages such as bottled soft drinks in retail outlets includes a substantially rigid support frame which is forwardly and downwardly inclined and which includes front and rear support surfaces and an intermediate support surface therebetween, the support surfaces being disposed in an imaginary downwardly and forwardly inclined straight line and with elongated channel shaped chutes of extruded plastic material mounted in downwardly inclined side-by-side relation on the frame so that rows of articles such as bottles may be mounted in each chute whereby removal of the front bottle in a chute allows the remaining bottles to slide downwardly so as to render the bottles more readily accessible at the front of the shelf. When unloaded each plastic chute is bowed upwardly and when loaded the chute is straightened so that its ends are disposed in contact with the front and rear support surfaces of the support frame and so that its intermediate portion is in contact with the intermediate support surface. This feature results in spring-like action when the front bottle in a row is removed whereby a slight upward movement of the chute occurs due to removal of the front bottle which results in jostling of the remaining bottles so that any friction which would tend to inhibit the downward and forward movement of the bottles is overcome by the jostling action of the chute.

Abstract: Abstract of the Disclosure A burner control apparatus includes a timing circuit for providing two successive timing intervals of precise duration, one being a pre-ignition timing interval and the other being an ignition timing interval.  The timing circuit includes a capacitor the charging rate of which determines one of the timing intervals and the discharge rate of which determines the other timing interval. In response to a call for burner operation a blower is energized to purge the burner of potentially explosive gases during the pre-ignition timing interval. When the pre-ignition interval comes to an end relays are energized to energize a pilot fuel control and an ignition control.  If a flame is sensed during the ignition interval a further relay is energized closing the ignition control and switching over from pilot to main fuel control.  If no flame is sensed during this interval a lockout actuator shuts down the entire burner and energizes an alarm.  If after establishment of normal burner operation the flame goes out, the cycle of two successive timing intervals is repeated.  The flame sensor and lockout actuator are connected directly to a power supply so that power is applied to the flame sensor and lockout circuitry independently of a request for burner operation but the control circuitry for initiating an ignition sequence is energized only after a request for burner operation.
