Abstract: ABRIDCEMENT             Medical specimens suspected of containing certain microorganisms are introduced into cards containing wells having culture media therein.  A reduction in the light transmitting characteristics of any well indicates the presence of a microorganism.  Each well is examined at periodic intervals by projecting a light through it.  This light is monitored by a plurality of detectors located beyond, but nevertheless, in alignment with the well, and each detector provides a signal which is proportional to the intensity of the light cast upon it.  If a detector registers an unduly large decrease in light transmission, whereas others associated with the same emitter do not, this probably indicates the presence of a bubble in the well, and the unduly large decrease is ignored.  This enables the machine to look around bubbles.  Adjustments are made for the change in light transmission caused by distortion of the flexible walls at the ends of the wells.  Each card has identification segments which are composed of different bars, and each bar is read by an emitter which projects light through it and a plurality of detectors which are illuminated by the emitter, unless the bar is blocked out with a marking.  A predetermined number of the detectors must register a light intensity above a prescribed threshold value to establish the absence of a marking in the bar which is read, and this enables the machine to disregard stray marks and foreign particles on the card.  The card is moved incre?entally through a reading head as the viewing wells and ?dentification segments on it are read.

Abstract: ABSTRACT      A method and apparatus for collecting and defibrinating blood in a flexible container.  The blood is collected in a flexible container of appropriate size into which is placed a sufficient quantity of glass beads or the like and a pre-determined amount of gas.  The flexible container is positioned within a vacuum chamber.  The vacuum drawn in the chamber expands the gas within the flexible container to permit only about one half of the container to fill with blood.  The flexible container is agitated causing the glass beads or the like to move rapidly through the blood and whip out the fibrin.  An alternative embodiment substitutes a reticulated material in place of the glass beads positioned within the container.

Abstract: ORIENTED TYPE SHANK SLOTTER                Abstract of the Disclosure The present invention relates generally to improvements in machines designed to form longitudinally extending slots in the shanks of fasteners and more particularly in fasteners having radially extend-ing wings at the entering end portion. The machine incorporates an indexing dial with blank receiving pockets at the outer periphery thereof to transfer the blanks from a loading station to a slotting station. An orienting station intermediate the loading and slotting stations creates a rotary force on the shanks of the fasteners causing them to rotate relative to the pockets. The pockets include means to limit the rotation of the shanks therein by interengagement of one of the wings with an abutment surface formed in a recess in the pocket. The orienting station revolves the blank about its axis until the shank is properly oriented for the slotting operation.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a varactor tuning system having a delinearization circuit for compensating for the non-linearity of the varactor diodes.  The system includes a keyboard, a memory, circuitry for addressing the memory in accordance with actuation of the keyboard and a digital-to-analog converter for generating a signal variable in accordance with the data at the addressed memory location.  The variable signal is delinearized to form the varactor control signal.  The first stage of the circuit includes a first analog switch, which is switchable in accordance with a pulse train, the duty cycle of which is a function of the stored tuning data, between a given supply voltage and ground, to form a first signal.  An intermediate signal, which is a function of the first signal, such as the time average thereof, is formed.  The second stage includes a second analog switch, which is switchable in accordance with the variable duty cycle pulse train, between an inter-mediate signal and ground to form an output signal proportional to the square of the input pulse train.  In a second embodiment, a maximum value circuit is utilized such that the output signal will be linearly proportional to the input signal for a selected range and proportional to the square of the input signal for the remainder of the range.

Abstract: METHOD AND APPARATUS OF CAVITY IDENTIFICATION OF MOLD OF ORIGIN                 ABSTRACT OF THE DISCLOSURE This invention relates to a system for determining which of a plurality of molds produced a particular con-tainer. A concentric ring code is molded into the bottom of each container as it is produced. The containers are then passed by a reading station, where light whose intensity is proportional to the angle of incidence is projected onto the bottom of the container.  Readings are taken of the variation of intensity of light reflected to a particular point in order to determine the position of rings on the con-tainer. Suitable electronics then decode the ring position to determine the container code, thus allowing identification of the mold which produced each container.

Abstract: ABSTRACT OF THE DISCLOSURE A calibrating and measuring circuit is disclosed for a capacitive probe-type instrument.  The capacitive probe, in contact with a surface to be measured, is connected to an oscillator which generates pulses, the frequency of which is adjustable, the number of pulses generated being a function of the texture of the surface being measured.  A digital counter is connected to receive, count and present the resulting summation to a visual numerical display.  In order to calibrate the instrument the capacitive probe is placed on a known specimen, the digital magnitude of which is loaded into the counter through a number of thumb switches.  The counter first counts down to this number, and then counts up to the number of remaining pulses.  The resulting count, called the offset number, is then transferred to a memory.  During measurement the memory loads the offset number into the counter, the counter then counting the offset number down to zero, before counting up to the amount of the received pulses, which are then displayed.  A logic arrangement initiates and controls both calibration and measurement.

Abstract: DEVICE FOR MEASURING VIBRATION AMPLITUDE     ABSTRACT OF THE DISCLOSURE         A device is provided for measuring the amplitude of vibration of a vibratory element.  The vibratory element or reed has a vane attached to it extending between opposed fiber optics light guides.  The vane has a mask portion which has slits forming alternating light-transmitting elements and opaque elements uniformly spaced in the direction of movement of the vane and lying in the path of light between the light guides.  One of the light guides has a stationary mask with at least one slit corresponding in size and orientation to those of the vane.  When light is transmitted from one of the light guides to the other while the vibratory member is vibrating, the light must pass through the slits of the masks and is alternately transmitted and cut off.  By counting the number of minimum light transmissions, therefore, the amplitude of the vibration can be determined.
