Abstract: Abstract of the Disclosure A method and apparatus for cooling hot bulk material, such as glowing coke, clinker, or sinter material, include a vertically oriented cooling tank into which the hot bulk material is introduced and in which the material flows downwardly under gravity and is discharged from an outlet.  At least two partial currents of cooling gas are fed into the cooling tank at respective feeding points therein, the feeding point being respectively arranged one over the other so that the cooling gas fed into the tank flows upwardly around the bulk material as the latter flows downwardly to cool the same with the cooling gas being corres-pondingly heated.  According to the invention, the cooling gas partial current fed into the cooling tank at a lower feeding point is at a lower temperature than the cooling gas partial current fed into the cooling tank at a feeding point which is arranged above the lower feeding point whereby the heat recovered is increased and the bulk material cooled to lower temperatures than has been possible heretofore.

Abstract: ABSTRACT OF THE DISCLOSURE     A shoe sole construction which features an outer sole having at least one opening through which a protrusion of a less dense midsole extends.  The cutout area of the more dense outsole decreases the overall weight of the sole, while the less dense protrusion aids in cushioning the foot to provide greater comfort and support.  Other protrusions may also be provided through other openings in the outsole to further lessen weight and increase the cushioning effect on the foot.  Additionally, grooves may be provided on the upper surface of the midsole to increase flexibility of the sole and further aid in cushioning the foot and providing peripheral support where needed.  The invention may be applied to athletic shoes, a woman's high-heeled shoe, or other footwear.

Abstract: INTEGRATED CARBON/INSULATOR STRUCTURE                 AND METHOD FOR FABRICATING SAME        ABSTRACT OF THE DISCLOSURE           A thin, integrated carbon/insulator structure, and a method for fabricating same, for use in a primary electrochemical cell.  A quantity of a wet carbon slurry material including a mixture of carbon black, water and/or isopropyl alcohol, and a binder such as finely-divided "Teflon"  (trade mark) in suspension is deposited onto a porous fiberglass substrate and rolled to a prescribed thickness.  The rolling operation causes a portion of the slurry material to diffuse into the surface of the porous fiberglass substrate and per-manently adhere to and unite with a surface portion of the fiberglass substrate in an integrated, inter-locking fashion.      The fiberglass substrate having the layer of carbon slurry material integrated therewith is then dried to cause the layer of carbon slurry material to dry and shrink to the form of a layer of carbon plaque having a network of cracks produced therethrough in a random pattern as a result of the shrinkage during drying.  The layer of carbon plaque at this stage re-presents an aggregation of porous carbon globules. The layer of carbon plaque is re-rolled to close cracks at the upper surface of the layer while simultaneously establishing a desired thickness for the layer.  After curing the above arrangement to increase adherence of the carbon globules to each other and to the fiber-glass substrate, an integrated carbon/insulator struc-ture of a desired size and configuration for use in a primary electrochemical cell can be cut out from the abovedescribed arrangement.

Abstract: Abstract of the Disclosure A system is provided for predicting in advance the result of a conditional branch instruction in a computer system.  The system includes a hash mechanism, a random access memory, an address buffer, a branch outcome result receiving means and a counter buffer.  The hash mechanism and memory use the input branch instruction address to produce a count which in effect is a way of weighting recent branch history to predict the branch decision.  The counts are stored in the random access memory (RAM).  The random access memory is addressed by the hashed branch instruction address to produce the system result.

Title: Fiber organizer for splice cases and terminals
Inventor: KORBELAK KENNETH N
IPC: B65H69/06
Filed: 1982-03-04
Granted: 1984-10-02
Abstract: ABSTRACT OF THE DISCLOSURE     Conventional communication cables must be spliced and so must fiber optic cables.  Special care must be taken at splice points or locations so as not to cause faults in the optical fibers and still have an organized packaging and splicing arrangement.          Optical fibers, unlike copper wire conductors, have memory.  This causes a problem, for example, since one can splice a copper pair, coil it up or place it in a splice case, and it will stay.  If the same thing is done on an optical fiber, it will not stay as placed and in fact will recoil like a spring.  This invention comprises a fiber organizer, made up of a series of channels, and it can accommodate and secure individual spliced fibers from each length of the optical cables.  Also the organizer provides a fiber splice support section in which the splices are placed upon completion.

Abstract: Abstract:     An advantageous low-resistivity gate level metallization for VLSI MOS devices comprises TaSi2 on polysilicon.  A two-layer tantalum-silicon composite initially overlies a relatively thin gate oxide film.  In accordance with this invention, the two-layer composite is anisotropically patterned in a two-step reactive ion etch-ing process.  Patterning is carried out before the layers are sintered to form TaSi2.  In the preferred embodiment, CC13F is utilized to etch the composite layer and some of the underlying polysilicon layer.  Thereafter, utilizing C12, the remaining polysilicon is etched in a step characterized by high selectivity with respect to the underlying gate oxide film.

Abstract: IMPLANTABLE TISSE-STIMLATING         PROSTHESIS     Abstract of The Disclosure There is disclosed an implantable tissue-stimulating prosthesis, such as a cochlear prosthesis, which can not only by implemented in single-chip form, but which also permits great flexibility in stimulation strategy and data transmission format.  Only sixteen electrodes are required for stimulating fifteen different sites.  Each site is stimulated by a biphasic pulse under control of two adjacent electrodes whose polarities are reversed in the middle of the site stimulation cycle.          Although the transmission scheme requires a pulse-width modula-tion format, the precise form of the format can be varied in order to accommodate widely different stimulation strategies.          For example, only a single site may be stimulated during each transmission frame or multiple sites may be stimulated during the same frame.  Although only one site can be stimulated at any instant of time, the system cycling is so fast that "simultaneous"  site stimulations are perceived.  The system is designed for minimum power usage, and its operation is fail-safe in that no site may be stimulated for longer than a pre-set time interval.

Abstract: ABSTRACT OF THE DISCLOSURE            A volume flow meter for the measurement of the flow quantity of a liquid, which meter comprises a cylindri-cal flow channel (3), which has an inlet point (10) and an outlet point (12) for passing the liquid to be measu-red through the measurement channel.  In the measurement channel, there is an axially moving, spring-loaded indicator piston (4), which is shifted by the liquid in the measurement channel into different positions depen-ding on the flow quantities.  In the wall of the measure-ment channel, there is an outflow slot (27) for the liquid, which slot becomes deeper from the inlet point to the outlet point.  The meter is provided with a reversing valve (17), by means of which the flow of the liquid to be measured can be guided through the by-passing channel (26) to the opposite side (3') of the indicator piston (4), as seen from the inlet point (10), so as to shift the indicator piston towards the inlet point.  This movement of the indicator piston wipes the wall of the measurement channel clean from impurities.          In the indicator piston, there is a flow connection from the said opposite side to the outflow slot of the measurement channel.
