Granted: 1981-12-15
Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure relates to a wind energy convertor comprising one or more vanes adapted to rotate about a common axle.  The vanes are spaced from the axle and each vane has its own axis around which it is adapted to rotate, the axis being closer to one side of the vane.  Means engageable and lockable with the oscillating vanes are provided to permit only limited rotary movement of each of the vanes around its own axis in such a way that the wind acting on the vanes when the means are locked, creates a torque around the common axle in the direction of its rotation.  Similar lockable means can also be used with stationa-ry vanes of a special air foil cross section, which lock the vanes fixedly on radial arms.  When unlocking the locking means, in both cases, the oscillating or stationary vanes take feather-ing position.

Abstract: ABSTRACT          An improved method for reducing the hydrogen sulfide and hydrogen polysulfide content of liquid sulfur, wherein, the liquid sulfur is brought into contact with a solid degradation catalyst con-sisting of alumina or a cobalt-molybdenum impregnated alumina at 250°F to 320°F, preferably 270-275°F, in the presence of a gaseous purge stream of air or oxygen enriched air.  In addition to exhibiting a many fold increase in rate of reaction relative to the use of either the catalyst without a purge gas or the purge gas alone, the use of an oxygen containing purge gas (such as wet air) in combination with the catalyst (such as alumina) shows a significant improvement, when com-pared to the use of a dry nitrogen purge in combination with the cata-lyst under similar conditions, in the kinetics of both the conversion of the polysulfides to sulfide (rate constant of 0.611 for wet air vs. 0.409 for dry nitrogen at 300°F) and the removal of hydrogen sulfide from liquid sulfur (rate constant of 0.877 in wet air vs. 0.62 for dry nitro-gen at 300°F).

Abstract: ABSTRACT OF THE DISCLOSURE            A data storage and retrieval system is provided utilizing digital or analog data input signals to energize one or more data recording heads which can produce a selection of sizes of alpha-numeric, pictorial ox digital coded images on a recording medium.        Where alpha-numeric or pictorial images are produced, the images are both directly human and machine readable.  Such alpha-numeric or pictorial images can be sequentially or simultaneously select-ively produced full sized and/or reduced substantially in size to form at least 24:1 or greater size reductions of these images on the same or different recording media.  Thus, for example, X-ray pictures or letters and the like can be simultaneously produced in reduced form on a microfilm recording medium for record storage purposes and full sized simultaneously of a recording medium for direct examination and delivery to third parties.  The reduced data   is directly human readable by projecting light preferably through the recording medium and magnifying and projecting the image on a screen.  Alternatively, the data is machine readable a by scanning small segments of the image with a capacitance or re-sistance responsive or photo-electric display device, to develop electrical signals which can operate conventional display readout devices.  The microfilm recording and electrical readout operations most advantageously are achieved by supporting the recording head or readout unit on a carrier which moves across the recorded area of the recording medium in a line-by-line scanning operation, carried out so rapidly that a complete page of informa-tion can be recorded upon the recording medium or read therefrom in at most a manner of a few seconds or less. In the most commer-cially significant form of the invention each data recording head capable of producing the reduced images is a Joule heat-producing device comprising one or more uniquely small current-carrying, heat-producing points each having dimensions preferably no greater than about 14 micron and less desirably no greater than about 20 micron.   The heat-producing points are spaced about a distance no greater than about the aforesaid dimensions.

Abstract: ABSTRACT OF THE DISCLOSURE             The system is for effecting transections, such as manual or mechanical delivery of commodities, services and money, while using identificands, such as credit cards, check cards, cards for automatic machines, coded tokens, keys and the like, provided with visually and/or mechanically readable identification and/or processing data, and while using a personal identification number for checking the title of the user of the identificand. Each identificand has inaccessibly incorporated therein a miniaturized integrated circuit (IC), in the form of a "chip", including plural memories for entry and storage of information therein, including identifying data and securing data. The memories for the identifying and securing data are chargeable only once, and at least the contends of the memory for the personal identi-fication number are available only within the identificand. The identificands are usable with either a checking device or an automatic machine including a source of potential, and the integrated circuit includes components activated, responsive to an input potential from the checking device or automatic machine, to effect internal checking of the identity and title of a user of the identificand. Input/output devices are included in the integrated circuit for establishing communication between the identificand and the verifying means. such as the checking device or automatic machine, and the identificand is constructed to prevent external access to the integrated circuit except through the input/output devices when connected to a verifier. A protective code, in the form of a random number, is entered into a first memory and simultaneously is printed on a concealed paper. The user also receives the printed protective code and enters the code into the identificand where it is compared with the stored protective code so that, upon a positive result of the  comparison, a release signal is produced for further processing. The user then selects a completely optional personal identification number and enters the same into a second memory in the identificand through the use of an encoder. The first and second memories are provided with  input gates which are automatically destroyed after entry, respectively, of the protective code and the personal identification number. Various other required information is then fed into other memories of the integrated circuit, through gates which are then destroyed so that the identificand cannot be initialized a second time.

Granted: 1981-01-13
Abstract: ABSTRACT OF THE DISCLOSURE Manufacture of grain and split leather is simplified by pre-tanning hide with a chromium-free tan until its shrinkage temperature is about 170 to about 185°F, splitting the pre-tanned hide to provide a grain intermediate and a split intermediate, shaving at least one of these intermediates, and chrome-tanning the shaved intermediate.  Shavings contain no chromium and can be disposed of by dumping, without significant environmental impact.  Before splitting, the hide can also be pickled to improve the splitting and shaving and make the unfinished hide better suited for shipping to remote geographical areas.  Entire hide treatment sequence can be effected with two stages in which batches of hides are loaded in a container such as tumbling drum; unhairing, bating and pre-tanning with or without a pickle, all in one stage, and final tanning, coloring and fat-liquoring in another stage.  Final chrome-tanned product has very good physical characteristics including unusually  high slot tear and is recovered in higher yield.

Abstract: ABSTRACT          The present invention relates generally to the drilling of large diameter shafts and, more partiuclarly, to the drill bits utilized in such applications.  Large diameter bits have been used in mines for the drilling of rescue shafts, ventilation shafts and access shafts.  A major problem with large diameter bits is that they are quite difficult to transport through small drifts or passages and very cumbersome to maneuver inside such structures.  Quite often the size of these passages severely restricts the type and size drill bit utilized.  Another problem encountered is that various size shafts are required for different applications in a single mine location.  As a result either various sizes of drill bits must be available, which is quite costly, or compromises must be made in hole size selection. The present invention obviates the above-mentioned shortcomings by providing a large diameter drill bit having demountable ear assemblies which enables one bit to drill various size bores.
