The calculator includes two edge indicators on the main member, one at a fixed location and the other slidable on the main member. The second member has a second set of indicia divided into subsets, each corresponding to an element of the first set of indicia.

Abstract: A process for making a food product having a high protein content of good nutritional profile and substantially without fiber, fats, or oils from grain that has been malted and subjected to a mashing operation to remove fermentable sugars. The grain so treated is dried by microwave heating and is subjected to liquid nitrogen to reduce the temperature of the grain greatly while subjecting the grain to mechanical action to remove the husks. The fats and oils are removed by a solvent, after which the remaining granular material may be ground to a flour.

Abstract: A chainstitch machine has an edge trimmer knife driven in vertical chopping motion adjacent the needle by a linkage actuated by an oscillating shaft that operates synchronously relative to stitch-forming components. The linkage includes a bracket oscillated by the shaft and a joint movable along the bracket between a first position, in which the axis of the joint is offset from the axis of the shaft to communicate oscillating movement to the knife, and a second position, in which the axis of the joint is concentric with the shaft and transmits no oscillatory movement. In the second position, the knife is retracted by the linkage to a location above the region through which work pieces move, but in the first position, the linkage moves the knife down so that part of the knife extends through the plane of the throat plate and is pressed against an edge of a throat plate insert by a small pressure slide entirely within a notch in the insert and guided by juxtaposed edges of the notch.

Abstract: Arbitration as provided in two separate levels, first between two signals that may contend for access to a system resource, such as a memory, and second between the winner of the first arbitration and another source, such as a refresh signal timer, that must have access to the system resource periodically and independently of requests for access from the other signals. The winning signal of the first arbitration is not continuous but is divided into intervals, and the refresh timer gains control of the second arbitration at the end of each interval of control by the winning signal from the first arbitration.

Abstract: A plastic pilfer-proof that comprises a ring, a plurality of inwardly directed hooks joined to one edge of the ring by hinge portions, and a weakened region is integrally molded with a main closure portion comprising a closed end and a skirt extending from the closed end and having an edge to which the pilfer-proof is attached during the molding. The hooks define sectors of a generally frusto-conical shell and extend inwardly and upwardly toward the closed end from the remote end of the ring. The hooks are released from the mold by rotating a mold portion that forms the respective hidden surfaces of the hooks and by pivoting the hooks radially outwardly toward the respective parts of the inner surface of the ring with respect to which the hidden surfaces are juxtaposed.

Abstract: To prevent a race in an asynchronous state machine branching from one state to either of two others, depending on which of two control signals arrives first, one of the signals is latched in the state just ahead of the branching state. The branching then takes place in the branching state upon arrival of the other signal but in a direction determined by the value of the latched signal. If the latched value indicates a wrong order of arrival, the machine releases the original latched value and latches an updated value of the one signal and returns to the branching state. The looping, with unlatching and relatching, continues until the latched value causes branching to take place in the proper direction.

Abstract: A process of separating husks from dried spent grains comprising the steps of subjecting dried a spent grains produced in a malting operation to a low temperature to embrittle the grains and then exerting mechanical force on the embrittled grains to separate the husks from the grains.

Abstract: A random sequence of 1's and 0's is generated by detecting excursions of a random noise signal above a certain positive voltage level, below a certain negative voltage level, and into an intermediate voltage range between the positive and negative levels. A 1 bit is generated each time the random signal shifts to a value above the first level and then into the intermediate range, where it must remain long enough to coincide with a clock signal. A 0 bit is generated each time the random signal becomes more negative than the second level and then shifts back into the intermediate range and remains there long enough to coincide with one of the clock signals. A signal generated at the end of each bit signal is used to clock that bit into a shift register. The same clocking signal also causes a counter to count a predetermined number of random bit signals and then to output the information stored in the shift register to a data bus for use as a random number signal.

Abstract: A molded flying disc with most of the weight concentrated in an outer annular ring and the central area in the ring covered by a thin lightweight sheet of material different from the molded material of the same thickness and diameter. The ring has a locking structure to hold an interlocking weight ring that may include another locking structure to hold an additional weight ring. The lightweight sheet may be colored or have artwork, such as a hologram, thereon.

Abstract: A wire connector to be soldered to a printed circuit mother board has two J-shaped outer legs and a central bight integrally formed with the legs and comprising juxtaposed contact portions to receive the edge connector of another such board. The outer legs and the central bight are in a common plane and the outer legs have flexure portions of reduced thickness. The thickness is reduced in the plane so that the flexibility of the wire is increased in that direction, making it easier to flex the legs to shift the location of the contact portions. Thus, a line of such contact portions on a row of clips can easily be brought into exact alignment to receive the other board without the necessity of using a jig to align all of the clips when they are attached to the mother board.

Abstract: Current to the stator coils 21-24 of a brushless DC motor is commutated by making transistors 42 and 43 alternately conductive by current through magnetically actuated switches 37 and 33 (or 51 and 52). These switches are actuated by magnetic fields from the permanently magnetized poles of a magnet 31 (or 47) attached to, but spaced from the rotor 11 and the stator poles 17-20. Depending on the polarity of the magnetic fields, the switches 37 and 33 (51 and 52) permit one of the transistors 42 or 43 to be biased by a voltage source that causes that transistor to become conductive and, simultaneously, connects the base of the other transistor to a voltage that causes that transistor to become non-conductive. Conductivity of the transistors 42 and 43 alternates as the rotor 11 rotates.

Abstract: Hashing of a key data signal is accomplished by utilizing a pseudo random number signal generator for generating a randomized signal in response to the key data signals and an output register for serially receiving the generated pseudo-random signal and for providing segments of the serially-received signal at its output. A counting circuit responsive to a preselected number of shift signals provides an output valid signal when the preselected number of shift signals has occurred and further shifts the pseudo-random number signal generator an amount corresponding to the preselected number of shift signals. The method of the present invention utilizes the steps of presetting the pseudo-random number generator and the counting circuit to an initialized state. The counting circuit is then loaded with a predetermined count whereupon key data is entered into the pseudo-random number generator so as to randomize the key data.
