In order to more efficiently form a pilaster, a pilaster form is disclosed which includes a first side unit and a second side unit together with a filler which is adapted to be interconnected with the first and second side units. The first side unit is adapted for interconnection with a first section of a wall form in order to form a first side of a pilaster. The filler is adapted for interconnection with the first and second side units of the pilaster form to form an outwardly facing surface of the pilaster. The second side unit is adapted for interconnection with a second section of the wall form in order to form a second side of the pilaster. With this arrangement, the filler is releasably secured to the first and second side units at any one of a plurality of positions in relation to the wall form to permit the forming of the pilaster in a plurality of depths relative to the concrete wall.

A diagnostic circuit of the present invention has serial command input and output pins separate from its serial data input and output pins. In one embodiment, the diagnostic circuit has one command register and one data register, the data register receiving serially an input signal and providing serially an output signal through an input pin and an output pin respectively. In another embodiment, the diagnostic circuit has one command register and multiple data registers. Each data register including a zero-length register, can be separately addressed. In yet another embodiment, multiple serial data input and output pins are provided together with multiple data registers.

An imaging method creates a two-dimensional image of a voltage distribution or a capacitance distribution of a substrate under test using an electro-optic modulator. A coarse modulator calibration determines the effect of non-uniformities in the modulator and determines a look-up table relating the gap distance between the modulator and the substrate to the intensity of the light emerging from the modulator. A positioning means calibration determines a look-up table relating control voltage to response by the positioning means. The modulator is moved over a portion of the substrate and then undergoes a positioning step, a fine onsite calibrating step, and a measuring step. The positioning step can be accomplished using the intensity of emerging light to determine modulator gap distance, and the response verses control voltage look-up table to determine a control signal to vertically position the modulator. The look-up tables permit the modulator to be position substantially parallel to the substrate at a desired gap distance using one step positioning.

The present invention is directed to a printing composition, in particular, a paste printing ink vehicle for effecting the setting of a paste printing ink by penetration into a substrate, the vehicle utilizing a vegetable oil fatty acid esterified with a simple alcohol or glycol as a solvent. The use of the esterified fatty acid as a solvent in the printing ink vehicle enables the production of novel petroleum distillate free paste printing inks having characteristics substantially similar to that of conventional petroleum distillate based printing inks.

Transgenic plants have been created which express an insect-specific toxin from a scorpion. The chimeric inheritable trait produced conditions of toxicity in the plant cells of toxicity to certain insects upon ingestion of plant tissues. The inheritable trait has also been cross-bred to plants transgenic to the Bacillus thuringiensis delta-endotoxin to produce plants having two independent insect-specific toxin traits. Insect feeding trails revealed additive toxic effects. A generalized approach for developing other insecticidal toxins as candidates for insertion into transgenic plants is also presented.

A semaphore circuit is disclosed which employs a pair of storage elements; an arbitrator, which is driven by the storage elements; and another pair of storage elements, which are driven by the arbitrator. The arbitrator includes a first and a second NOR gate. One of the inputs of the first NOR gate is connected to the output of the second NOR gate one of the inputs of which is connected to the output of the first NOR gate.

The combination of a seven-port random access memory (RAM) unit, a funnel shifter, a mask generator, an arithmetic logic unit (ALU), a merge logic unit, a number of multiplexers, and three bi-directional data buses are configured to form a thirty-two bit, cascadable, microprogrammable, bit-slice suitable for executing complex operations such as those which require that several operands be read from the memory unit, be rotated in the funnel shifter, be operated upon by the arithmetic logic unit, be merged in the merge logic unit, and the result be written back into the memory unit all in a single cycle.

A method is disclosed for producing fine cobalt metal powder. The method involves digesting a cobaltic ammine halide in an aqueous solution with a mineral acid at a temperature of at least about 110.degree. C. for a sufficient time to decompose the cobaltic ammine halide to form an amorphous hydrated cobalt oxide containing precipitate. The digestion step is carried out at a suitable pressure in a sufficiently closed vessel to permit the temperature to be attained in the solution. The aqueous solution of the cobaltic ammine halide contains from about 5 grams of cobalt per liter up to the limits of solubility of the cobaltic ammine halide. The mineral acid is present in an amount sufficient to result in the subsequent cobalt metal powder having a Fisher Subsieve Size of no greater than about 2.1. The cobalt containing precipitate is separated from the resulting solution and reduced to form the fine cobalt powder.
