Abstract: ABSTRACT OF THE DISCLOSURE         Two-dimensional digital computers and computer devices operate in parallel on rectangular arrays of digital radiant energy optical signal elements which are arranged in ordered rows and columns.  Logic gate devices receive two input arrays and provide an output array having digital states dependent only on the digital states of the signal elements of the two input arrays at corresponding row and column positions.  The logic devices include  an array of photoconductors responsive to at least one of the input arrays for either selectively accelerating electrons to a phosphor output surface, apply-ing potentials to an electroluminescent output layer, exciting an array of discrete radiant energy sources, or exciting a liquid crystal to influence crystal transparency or reflectivity. An image combiner/duplicator serves as an interface device for either converting two spaced apart input arrays to a combined input array or for converting an input array to two spaced apart output arrays.  Interconnecting  devices provide an out-put array having signal element digital states dependent on the states of non-corresponding input signal elements.   Such devices include  a slider for translating the output array with respect to the input array; a twister for rotating the output array by a multiple of ninety degrees; an interchanger of rows and columns; an inverter of row or column element order; a magnifier responsive to a subarray of an input array; a spiller device responsive to the state of a single input element; a contractor device having an output signal element responsive to a digital 1 of any input element; a sweeper device for producing ?dundant rows or columns corresponding to a single input row or column.  Memory devices utilizing the gates in conjunction with regenerative feedback also serve to threshold analog images.  An A/D converter system converts an analog input image into bit planes.  An array computer system organization includes array mask gating for performing different operations simultaneously on different image portions.

Abstract: ABSTRACT OF THE DISCLOSURE             A current sensor provides a voltage signal which is proportional to the average current flowing through a semiconductor junction.  This voltage is then applied to a first analogue circuit which produces an output voltage indicative of the average power dissipated at the junction. This voltage is then applied to a second analogue circuit which outputs a voltage signal indicative of the temperature difference between the junction and the heat sink.  The voltage from the first analogue circuit is also applied to a third analogue circuit which outputs a voltage signal indicative of the temperature difference between the heat sink and the ambient.  The ambient temperature is sensed by an ambient temperature sensor which outputs a voltage signal indicative of the ambient temperature.  A voltage summing circuit sums the output voltages from the second and third analogue circuits and from the ambient temperature sensor, and produces an output voltage indicative of the junction temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           A multi-channel analog system comprises a plurality of channels each being adapted to receive analog signals from a signal source such as a seismic sensor.  A multiplexer multiplexes the analog channels prior to converting the channels' signals into digital numbers.  Each channel has a DC blocking capacitor connected to one terminal of a normally-open multi-plexer switch; the other terminal of the switch is coupled to a multiplexer bus.  In accordance with this invention, the bus is connected to a common resistor.  Control means consecutively close the multiplexer switches so that the capacitor whose switch has been closed forms a high-pass filter with the common resistor.  The resistor is preferably connected as the input resistor to an operational amplifier.  The capacitors, the multiplex-er, and the common resistor form a multiplexer-commutated high-pass filter which is particularly adapted for multi-channel seismic systems.

Abstract: HUE CORRECTION APPARATUS HAVING A RESTRICTED RANGE                  Abstract of the Invention Hue correction apparatus of the flesh tone correction type is provided.  Chrominance signals are monitored on a dynamic basis and the phase of a color subcarrier reference signal is automatically altered when the chrominance signals are in the vicinity of the flesh tone (+I) axis.  The phase of the reference subcarrier is altered, making use of a wide bandwidth phase detector, by controllably adding a portion of an amplitude limited chrominance signal to the subcarrier so as to shift the subcarrier phase towards the phase of the chrominance signal.  The range of angles and response of the apparatus is restricted by means of an offset bias control coupled to the chrominance signal adder circuits.  Green and blue tones are relatively unaffected by the system operation.          Good transient response of the correction apparatus is provided at sharp color transitions.

Abstract: ABSTRACT OF THE DISCLOSURE        A device for both shipping and starting the growth of plant seeds.  Two container portions are mutually engageable to form a receptacle for the transportation of plant seeds and cylindrical disks of plant growth matter.  The container por-tions are substantially identical and interchangeable as the repository and cover member of the receptacle.  Each container portion has three compartments formed by three partitions rising orthogonally from the base of the container and abutting equi-angularly about the center of the base.  A pair of ribs is dis-posed in each compartment between adjacent abutting partitions, and a vertical projection extends upward from the side of the container within each compartment generally along a line bi-secting the angle formed by adjacent abutting partitions.          Preferably, an upright member is attached to the end of each of the partitions, rising from the base of the container to a height slightly less than that of the upper edge of the con-tainer.  Each pair of ribs supports the bottom of a disk of plant growth matter, while the adjacent abutting partitions, upright members and projection engage the periphery of the disk to prevent lateral movement.  When transporting the device, six disks are located in the repository, two being stacked vertically in each compartment.  When the cover is placed on the repository, it is situated so that an upright member in the cover extends above each compartment in the repository.  The upright member can be of a sufficient height to securely retain the disks, or the upright member, in combination with printed matter, such as instructions and seed packages placed on top of the stacks of disks, can securely retain the disks.

Abstract: ABSTRACT OF THE DISCLOSURE:       The invention is concerned with a bandage adapted for application to a mammalian body having a wound, lesion or the like, which comprises: (a) a bandage substrate adapted for application to the body; (b) a single metallic electrode, at least a part of this electrode being in direct contact with the body; and (c) collagen and/or an ionizable or polar medi-cament in electrically co-operative relationship with the electrode.  The bandage is capable in use of forming a galvanic couple between the single electrode and the body when applied over the wound, lesion or the like, and producing, without use of an external power source, a local current effective for iontophoresis or for applying a small electric charge to the body.  The bandage of the invention has surprisingly been found to be capable of creating a galvanic couple between the single electrode on the one hand and the body of the mammal on the other.  When this bandage is applied to a mammalian body, natural body fluids or applied electrolyte activate the bandage and the desired voltaic effect is created, which causes a medicament contained in the bandage to migrate deeply within a wound or lesion.
