Abstract: "Power Saving System for Time-Division Multiple Access Radiocommunication Network"                          ABSTRACT     In a time-division multiple access (TDMA) communication network, a power saving system interleaves a power saving control signal at periodic intervals with a selection signal and information signals and transmits the interleaved signals from a master station to slave stations.          A plularity of power cut-off circuits are associated respectively with the slave stations for individually cutting off power supplies to the slave stations for a predetermined period in response to the control signal.  A detector is provided for detecting the moment a connection is being established, idenfifying the slave station establishing the connection and selectively inhibiting the power cut-off circuit associated with the identified station from responding to the control signal, while allowing the remainder of the power cut-off means to respond to the control signal.

Abstract: ABSTRACT OF THE DISCLOSURE        To obtain an efficiency of about 10% in photo-electrochemical solar cells,  the pairing of semi-conductor material for the working electrode and composition of the electrolyte liquid is of critical importance.  The semi-conductor material therefore should not be too expensive, and should have a short absorption length for light and be resistant to photocorrosion.   Further,  a non-toxic electrolyte should be employed permitting operation even without a hermetic seal.  The photoelectrochemical solar cell of the invention utilizes a CuInSe2 or CuInS2 in a ternary compound, for the semiconductor material, which is used with an iodine-iodide solution an an electrolyte.  In a method of fabricating a substrate for such a clear cell, a surface film is produced on a single-crystal semiconductor material, particularly CuInSe2,  or a polycrystalline material, by immersing the semiconductor material after an etching and rinsing process into the electrolyte solution and simultaneously exposing it to light and polarizing it cyclically between two potential limits.  Upon repeating this procedure several times, the material is exposed to light at the operating point for a longer time.  The film thereby produced yields a p-n junction n the boundary layer.          The advantage is a very high potential for an efficient solar  energy  conversion  and  the  growth  of  the heterostructure can be controlled.

Abstract: ABSTRACT OF THE DISCLOSURE An elevator system in which distance pulses are generated in response to travel of an elevator car and used to update a car position counter.  The difference between the car position count and a count representative of the location of the target floor is determined when the elevator car reaches a predetermined distance from the target floor, and this distance-to-go (DTG) count is used to provide a speed pattern for decelerating and landing the car at floor level.  A zone of fixed length is pro-vided on each side of each floor, and when this zone is detected, the DTG count is compared with a count repre-sentative of this fixed length.  If they differ within a predetermined tolerance, it is known that a proper landing will or can be made, and the DTG count is changed to the correct value at the instant the zone is detected.  Door preopening may be enabled at this time.  If the difference exceeds the predetermined tolerance, no corrective action is taken, the door preopening is not enabled.  The amount of the difference may also be subjected to various checks for determining if the elevator car should be taken out of service, or allowed to continue to run.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus and method for the manufacture of glass fibers utilize a bushing confining a body of molten glass over an orifice plate which may or may not have depending tips.  Interposed in the glass body is a plate or other device for reducing the pressure of the molten glass body over the orifice plate to a pressure no greater than atmospheric pressure.  The orifices are of relatively large diameter incapable of imposing a substantial pressure drop on molten glass flowing therethrough. Each tip contains a pool of molten glass at no greater than atmospheric pressure and, during fiber attenuation, a forming cone is drawn from the pool in each tip.  The cones are located in the tips, each cone is smaller than the surrounding tip and each cone is stabilized on the interior tip wall by an annular glass portion integral with the cone.          The process is dripless, since upon fiber interruption at any given tip, the molten glass pool remains in the tip.

Abstract: A B S T R A C T            This invention relates to a method of recovering gold values from an activated carbon support which includes placing the support with the gold values adsorbed thereon in a column having a first end and a second end, introducing deionised water as an eluant into the column near the second end, collecting the eluant containing the gold values near the first end of the column, while continuing the flow of eluant through the column, periodically removing a portion of the activated carbon support from which substantially all the gold values have been eluted from the column, and replacing the removed portion of the support with a further amount of the support having metal values captured thereon.  This method is a batch-continuous method in that the activated carbon support is passed in the form of discrete slugs through the column and the eluant is continuously passed through the column countercurrent to the support.  This method has several advantages over known elution methods, including the fact that less eluant is used and that the carbon residence time in the column is substantially reduced.
