Abstract: TAKE-OUT TONG ASSEMBLY             ABSTRACT OF THE DISCLOSURE            Apparatus for taking newly formed glass containers from a blow mold and transferring the containers to a dead plate wherein the take-out tongs for engaging the containers are mounted on a pair of holders that are pivoted like scissors relative to each other.  A piston motor is pneumatically driven in one direction to cause the tongs and holders to close, and a spring, urging the piston in the opposite direction effects the opening of the tongs.  When the tongs are open, the connection between the piston rod and the holders is a toggle linkage when the links are in a straight line preventing "winking" movement of the tongs toward closing by the fact of the toggle arrange-ment.  Thus machine air closes the tongs and a fairly light spring force opens them.

Abstract: ABSTRACT OF THE DISCLOSURE             A vertical feed chute includesa a feed roll for feeding fibers from a surge section in its upper end to a formation section in its lower end.  A stationary, perforated condenser plate is secured to the lower, discharge end of the chute, and has thereon æ concave surface which extends beneath the chute discharge opening, and beneath a metering roll that is mounted to rotate in the discharge opening in confronting relation to the condenser plate.  A mat of fibers is drawn from the discharge opening into a nip between the con-denser plate and metering roll where in mat is compressed and then fed to the input of a carding machine, or the like.  The metering roll is mounted for limited reciprocable movement normal to its axis, and toward and away from the concave condenser surface.  In one embodiment the roll is positively driven by pneumatic means toward or away from the concave surface depending upon the density of the mat entering the nip.  In another embodiment the metering roll ~ mounted to reciprocate in response to changes in the thickness of the mat; and this movement is used either to increase or decrease the rate of which fibers are fed to the formation section of the chute, thereby to effect a corresponding increase or decrease in the thickness of the mat.

Abstract: ABSTRACT A vortex flow metering apparatus is equipped with a sensor unit having first and second piezoelectric sensors fixed in a cavity of a vortex generator which is partly located in a duct through which a measuring fluid flows to produce Karman's vortex according to the fluid velocity.  A first conversion amplifier in which a signal from the first piezoelectric sensor is applied and a second conversion amplifier in which a signal from the second piezoelectric sensor is applied are provided.  An operator in which an output of the first conversion amplifier and an output of the second conversion amplifier are applied removes a noise component due to a disturbance vibration.  The first and second piezoelectric sensors are arranged at two points at which the stress distribution of the noise component due to the disturbance vibration and the stress distribution of the signal component due to the vortex dynamic lift are different from each other.  The invention greatly reduces the noise component in the output signal from the vortex generator.

Abstract: ABSTRACT OF THE DISCLOSURE         A low-cost printer is provided for use with data processing equipment.  A light-shielding retainer provides a substantially continuous sheet supply of printing medium which is light sensitive and heat developed.         The printing medium has strips of a conductive-resistive material on one side.  The medium is moved past a processing station.  A first portion of the station includes an array of light emitting elements and a second portion in-cludes electrical contacts which engage the strips and apply current through them thereby heating the medium sufficient for developing the medium thus visibly exposing and fixing the characters on the medium.  The use of discrete strips interrupts the spread of heat and limits the zone of heating of the medium to a region  adjacent the printer.  This permits light exposure and heat curing to occur at approximately the same location.  Thus, any errors will be more readily noticed.

Abstract: ABSTRACT OF THE DISCLOSURE    A medication compliance monitoring system consisting of a blister pack having an array of plastic blisters defining compart-ments for mediation, with a frangible non-conductive backing sheet having conductive traces behind the compartments which are respectively ruptured when the medication doses are removed. The blister pack is detachably connected to an electronic memory cir-cuit via a multi-terminal male connector tab on the backing sheet, wired to the conductive traces, and a corresponding female con-nector with terminals wired to the electronic memory circuit. The electronic memory circuit addresses each individual trace per-iodically at a constant time interval over a predetermined extended period of time to determine if it is intact. The electronic mem-ory circuit detects the ruptures and stores the time data thereof over said extended period of time. During the patient's follow-up visit a microcomputer is employed to retrieve the dose-removal-time data from the memory circuit ; it processes the data and pro-vides a display of the compliance information.A socket adapter is used to alternately configure the electronic memory circuit for data acquisition and extraction. The socket adapter is in the form of a multiple-pin jumper plug engageable in a multi-contact socket connected to the memory circuit. Insertion of the plug configures the memory circuit for data acquisition. Removal of the plug con-figures the memory circuit for data retrieval and processing by the microcomputer. In a typical embodiment there are 42 blisters whose associated conductive traces are addresses every 15 minutes over an extended time period which may be as much as 85 days.
