Abstract: ABSTRACT OF  THE DISCLOSURE         One form of conventional earth anchor device includes an anchor which is driven into the ground as the leading element of a combination.  Thus, the anchor must be streamlined to facilitate ground entry which is incompatible with the need for a curved body facilitating anchoring.          Another problem is the need for anchors having large bearing areas which require considerable effort for insertion into the ground.  A device providing a solution to these problems includes a tube or sleeve with a sacrificial blade releasably mounted in the bottom end thereof for driving into the ground, and a rod carrying an anchor and a spring biasing the anchor outwardly, whereby the sleeve can be driven into the ground, following which the rod is held down while the sleeve is extracted, leaving the blade, and, when the anchor and spring exit the sleeve, the spring biases the anchor into a ground engaging position.  An upward pull on the rod pivots the anchor into a secure anchoring position in the ground.

Abstract: Abstract of the Disclosure Fine featured devices are produced by a series of fabrication steps including exposing selective surface regions to irradiation, e.g. to an ion beam, generally to result in removal of masking material within irradiated regions. In most instances, subsequent etching is under conditions such that bared material is preferentially removed. Etch-removal and irradiation are such that overgrown material is of device quality at least in etched regions. The inventive process is of particular value in the fabrication of integrated circuits, e.g circuits performing electronic and/or optical functions. The inventive process is expediently used in the fabrication of structures having minimum feature size of 1 micrometer and smaller. Patterning is dependentupon masking material of a maximum thickness of 100 .ANG..

Title: Determining propositional logic theorems by applying values and rules to triplets that are generated from a boolean formula
Inventor: STALMARCK GUNNAR M N
IPC: G06F17/10
Filed: 1990-06-12
Abstract: The invention relates to a method and apparatus for theorem checking with the intention in so-called tautology checks of establishing whether or not all possible attributions of the truth values (0 and 1) to variables in a boolean formula render the formula true.  The problem of known techniques is that checking of the truth content is effected against all variables in an original formula, which requires many calculations to be made and which is highly time-consuming. According to the invention, an original formula is divided into part-expressions, so-called triplets, each corresponding to a part-formula of the original formula, whereafter logic 0:s and 1:s are instantiated (allotted) to variables in the triplets for the purpose of checking the truth content.  The check is thus made against triplets instead of against all variables in the original formula, therewith greatly reducing the number of calculations necessary and providing a considerable saving in time. Apparatus for carrying out the method includes a sequence unit for controlling the calculation sequency, a generator G for generating sequences of ordered variables, a permanent unit P for storing triplets, a plurality of arithmetical units, evaluators (E), and an analyzer A operative to analyze the result obtain from all calculations

Abstract: ABSTRACT OF THE DISCLOSURE    A combination of raw coal and water is introduced as a slurry into a vessel.  Chemicals are introduced at a feed inlet.  The mixture is reduced by interaction with a bed of agitated grinding balls.  Air is introduced into the lower portion of the vessel and forced upwardly through the circuitous passages among and between the grinding balls.  The rising air bubbles carry the more hydropholic product upwardly into a froth compartment of the vessel and through a discharge outlet of the vessel.  Wash water is introduced into the upper portion of the vessel and descends through the froth and the ball passages carrying entrained and less hydrophobic particles into the grinding chamber.  The non-floatable material flows downwardly form the grinding chamber to a refuse zone for discharge as refuse from the vessel.

Abstract: ABSTRACT           A base voltage of a regulator transistor is developed during normal operation in a filter capacitor coupled to a flyback transformer of a horizontal deflection circuit. After a transition to a standby mode of operation, the deflection circuit is disabled and the capacitor begins discharging. The emitter of the transistor is coupled to a load circuit. A supply voltage is coupled to the collector of the transistor during both standby and normal mode. To reduce the loading of a standby power supply that generates the collector voltage as long as the capacitor is not fully discharged, an active turnoff of the regulator transistor is provided immediately after the receiver goes into the standby mode of operation so as to actively turnoff the current drawn by the transistor.
