Abstract: D-23,134 SIMULATION CIRCUIT EMPLOYING SWITCHED CAPACITORS                        by Man Shek Lee Abstract of Disclosure A circuit for simulating the parallel combination of a floating inductor and capacitor in the bilinear and LDI domains has a pair of nodes receiving an input voltage and connected to input terminals of associated first and second voltage followers.  A first capacitor C1 is alternately or periodically connected across the output terminals of the voltage followers for sampling the input voltage, and connected between the output of the second voltage follower and the input terminal of an integrator including a second capacitor C2 which integrates and stores the charge voltage on Cl.  A third capacitor is periodically connected to the nodes for sampling the input voltage, and connected between the output terminals of the first voltage follower and the integrator for subsequently also sampling and storing the integrated voltage on C2.  The sum of the input voltage and the integrated voltage that is stored by C3 is discharged to the new input voltage when C3 is again connected across the nodes.  The parallel combination of a grounded conductor and capacitor is simulated by replacing one of the voltage followers with a short circuit and connecting the associated node to ground.  An inductor alone is simulated across the nodes by proper selection of values of the three capacitors.

Abstract: A RECESSED LIGHTING UNIT            ABSTRACT OF THE DISCLOSURE     A recessed lighting unit for supporting an energizing lamp adapted to fit into an electrical socket using a housing.  The electrical socket and lamp are mounted in the housing.  The housing includes an opening for the passage of light from the lamp to the area to be illuminated.  A source of power runs to the socket through a wireway.  A heat protection mechanism interrupts the flow of electrical power to the lamp and socket upon the generation of excess heat in the vicinity of the housing.  The heat pro-tection mechanism is mounted immediately adjacent the housing in the wireway and forms a structural unit with the housing and a junction box.

Abstract: AN IMPROVED PARALLEL ARM WINDSHIELD WIPER ASSEMBLY    Abstract of the Disclosure An improved parallel arm windshield wiper assembly is disclosed of the type in which a drive spindle projects through an aperture formed in a windshield.  The drive spindle is connected at one end to a motor and has a wiper arm attached to its opposite end.  The wiper arm supports a wiper blade which is aligned parallel to a control arm which is also pivotally connected near the outer end of the drive spindle.  The ends of the control arm and the wiper arm are connected together by a wiper blade support member which supports a wiper blade.  The improvement includes a spacer tube and a sleeve coaxialy aligned about the drive spindle with the spacer tube being on the outside.  A bracket is mateable with the outer end of the spacer tube and is held in place by a nut threaded onto the sleeve.          The bracket is angled outward away from the windshield and has a stud secured to its distal end to which the control arm is pivotally attached.  The position of the stud is such that a line drawn between the centerline of the drive spindle and the centerline of the stud combines with the wiper arm, the control arm, and the wiper blade support member to form a parallelogram.  This parallelogram permits the wiper blade to maintain a constant orientation throughout its oscillatory sweep of the windshield.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a device for feeding printing plates 33 and transporting them onto an exposure table 1, with the aid of rollers 10, 10', 10" . . ., 11, which are arranged in pairs and are fastened, by means of blocks 5, 6 on two roller rails 4, 4'.  The roller rails 4, 4' are located at both sides of the exposure table 1, in the transport direc-tion.  The transport rollers 10 which are positioned first in the transport direction of the printing plate 33 are installed on pivoting blocks 5, which are pivoted outwardly before the printing plate 33 is deposited and, after the printing plate 33 has been deposited, are swung into contact, in order to take over the roller-transport, together with the remaining rollers.  As soon as the printing plate 33 has reached its exposure position, the roller rails 4, 4' are, in their entirety, swung away from the exposure table 1, parallel to themselves, thus enabling the printing plate 33 to be exposed out to its outer edge without hindrance.

Abstract: Load Skidding Vehicle Having A   Positionally Biased Grapple Abstract load skidding vehicle utilizing a grapple assembly for grasping loads.  The grapple assembly is pivotally connected to a boom which extends rearwardly from and is connected to a chassis.  The grapple assembly is pivotable relative to the boom by a hydraulic cylinder connected to the grapple assembly and chassis,  Displacement of the hydraulic cylinder provides pivoting of the grapple assembly to an optimum load skidding position.  Means are provided for maintaining the optimum skidding position for the grapple assembly with a biasing force during skidding by permitting the grapple assembly to pivot away from the initial skidding position when a predetermined skidding force is encountered.  When the skidding force falls below the biasing force magnitude, the grapple assembly is again pivoted toward the initially set skidding position.

Abstract: RANGE-ENABLED INFORMATION SYSTEM    FOR PLURAL MOBILE OBJECTS            Abstract of the Disclosure An information system for communicating information from each of a plurality of separate locations to each of a plurality of mobile objects includes a beacon at each location and a beacon triggering and detecting apparatus mounted on each object. Each beacon triggering and detecting apparatus is assigned a predetermined and unique time window within a common system cycle. During the initial portion of its window, the beacon triggering and detecting apparatus transmits a trigger signal at a frequency f1' with the trigger signal as transmitted having a substantially constant amplitude and with frequency f1 being chosen so that the intensity of the trigger signal decays as the cube of radial distance from the object. If the object is within a predetermined beacon trigger range of a location, the beacon at that location detects the trigger signal and transmits a beacon signal at a frequency f2 (substantially greater than frequency f1) during the terminal portion of the window which is detected by the beacon triggering and detecting apparatus, The beacon signal contains any information that is desired to be communicated from the location to the objects, such as the identity or location of the beacon. Provision is made for synchronizing the various beacon triggering and detecting apparatus by signals at a frequency f3 (that is distinct from frequencies f1 and f2) from a base station, for disabling operation of a given beacon triggering and detecting apparatus upon the failure of that apparatus to be synchronized by thebase station for a predetermined period of time, and for transferring the information that has been communicated from each location to each object to the base station for further processing and centralized information display.

Abstract: ABSTRACT OF THE DISCLOSURE           The preferred embodiment of this invention includes a logging sonde, an elongated pair of oppositely polarized piezoelectric plates connected to each other by their flat surfaces, and an electrical pulse applying means for applying electrical pulses across the pair of plates so as to bend and vibrate the plates in a direction perpendicular to the length of the plates.  Vibration of the plates in a fluid contained in a well creates in the fluid a positive compressional wave in one direction and simultaneously a negative compressional wave in the opposite direction. The two compressional waves will interfere to produce a dipole shear wave in the earth surrounding the well.  The dipole shear wave arrival is detected at two locations in the fluid spaced longitudinally along the well from each other and from the plate.  The ratio of the time interval between the detections of the dipole shear wave arrival at the two locations to the distance between the two locations yields the shear wave velocity of the earth around the well.  The length of the plates may be selected to generate dipole shear waves with frequencies in a preferred range so as to improve shear wave signal to compressional wave noise ratio.
