Abstract: METHOD OF PROGRAMMING OF JUNCTION-PROGRAMMABLE READ-ONLY MEMORIES                         Fu C. Chong ABSTRACT      A method of programming a cell in a PROM, wherein the cell comprises a bipolar transistor having a floating base, comprises applying a current rising with time across the emitter to collector contacts of the bipolar transistor with the collector contact serving as the reference potential, measuring  the time at which the rise in voltage suddenly stops and the voltage drops a small amount, and then holding the current for a selected time following the voltage drop, thereby to insure that the emitter base junction of the bipolar transistor is destroyed while at the same time not damaging the base collector junction of the bipolar transistor.

Abstract: ABSTRACT           An osmotic device is disclosed for delivering two beneficial drugs to an environment of use.  The device comprises a semipermeable wall surrounding a lumen divided into a first compartment containing a drug that is separated from a second compartment containing a different drug.  An orifice through the wall communicates with the first compart-ment for delivering drug from the first compartment, and another orifice through the wall communicates with the second compartment for delivering drug from the second compartment. In operation, drug is dispensed separately from each compart-ment by fluid being imbibed through the wall into each com-partment at a rate controlled by the permeability of the wall and the osmotic pressure gradient across the wall against the drug in each compartment thereby producing in each compartment a solution containing drug that is dispensed through their orifices at a controlled and continuous rate over a prolonged period of time. The partition within the device dividing lumen into two compartments is substantially dimensionally stable.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for measuring a gas partial pressure in a living body on the basis of the principle of polarography.  A gas partial pressure sensor includes a biomedical electrode inserted in the living body.  A temperature sensor is further provided to measure a temperature of the living body.  A polarographic current value measured by the gas partial pressure sensor is corrected to a current value at a reference temperature depending on the temperature measured by the temperature sensor.  Then the gas partial pressure at the reference temperature is determined based on a working curve which represents a relationship between the corrected polarographic current value and the gas partial pressure at the reference temperature.

Abstract: Abstract The diskette drive described herein reads and writes information on a flexible magnetic disk stored in a rigid diskette cartridge.  The drive contains apparatus for loading and registering the cartridge in the drive without the assistance of a loading tray or cartridge carrier.  The disk drive spindle, the recording head and cartridge position registration pins all protrude into the insertion path for the cartridge.  The spindle and pins are shaped and positioned so that the cartridge will not strike the recording head as it is inserted.  Spring fingers are provided to bias the cartridge down against the spindle and the registration pins.  When the cartridge is fully inserted, it snaps into a registered position over the pins, the spindle and the recording head.  In addition the cartridge contains a truncated corner that cooperates with a blocking member in the insertion path to prevent the cartridge from being improperly inserted.

Abstract: ABSTRACT OF THE DISCLOSURE     COMPOSITE WOUND DRESSING       The multilayered composite wound dressing comprises of a semipermeable membrane, a permeable supporting and reinforcing layer, and a non-stick, self-sealing biodegradable tissue interface. The semipermeable membrane may be synthetic collagen, an alginate or a biocompatible polymer and it controls the rate of water vapour transmission from the wound surface. The permeable supporting and reinforcing layer provides mechanical strength and is usually a textile fabric which may also be made electrically conductive by coating it with a carbon-doped silicon or natural rubber or depositing metal on the fabric. Alternatively, an activated carbon cloth fabric can also be used. The biodegradable tissue interface may be synthetic collagen, sodium-calcium alginate or collagen-alginate complex, and it provides non-stick haemostatic sealing and aids the wound repair processes. For topical medication, growth promoting, antibacterial, anti-allergic and therapeutic agents may also be incorporated.        The conductive supporting and reinforcing layer can be used to provide electrical charge transfer and stimulation of the wound using external fields which has been shown to enhance the wound healing process, produce post-operative pain relief and bacterial-inhibition. The composite wound dressing has application inter alia in treating general surgical wounds, burns, bedsores, infected ulcers, donor sites for skin grafts or alternatively can be used for electrode dressing in transcutaneous and functional stimulation.

Abstract: Abstract Selective Bromination Process Alkyl aromatic hydrocarbons and their halogenated substitution products are partially brominated in a liquid phase reaction within the still head of a distillation system. Liquid bromine is introduced in the still head through a side-arm, is mixed with condensed hydrocarbon in a mixing zone and reacted in a chamber when irradiated with UV or visible light of wavelength shorter than 550nm.  The higher boiling partially brominated hydrocarbon formed is recovered via a distillation column and unreacted materials are recycled.  The brominated products, particularly tetrafluoro-p-xylyl bromide and pentafluorobenzyl bromide, are useful intermediates in the synthesis of, for example, insecticidal compounds.

Abstract: ABSTRACT OF THE INVENTION A two mode control system for controlling the position of the tape in the buffers of a reel to reel tape system is presented.  A constant current control mode is used when the tape position error is  large,  and a  linear position control  is  used  when  the  tape position error is small.  Control is switched between the two modes, as  required  by  the  magnitude  of  the  error,  thus  achieving  the desired control while using minimal power.  The system handles the worst case capstan reversal with a minimum turnaround time.   Tape position is sampled at a rate that is a multiple of the mechanical resonance of the tape in the buffers, thereby minimizing the effect of the resonance on the measurement.   The system further uses a feedforward signal during the  initial  stage of motor control  to compensate for the lag in the position sensor.

Abstract: "PROCESS AND APPARATUS FOR THE ANAEROBIC  BIOLOGICAL PURIFICATION OF WASTEWATER"                              Abstract In a process for the anaerobic biological purification of wastewater containing organic pollutants, the wastewater to be purified is conducted through two series-connected reactors (2 and 5) operated under anaerobic conditions. In order to achieve a shortening of the residence time for the wastewater to be purified and thereby a savings in total reactor volume, the pollutants contained in the wastewater, which are present partially in the undissolved, partially in the macromolecular state and are only slowly metabolizable under anaerobic conditions, are retained in the first reactor (2) by means of a filter medium (3) arranged in the first reactor (2).  On the other hand, polIutants initially present in the dissolved condition in the wastewater and which are readily degradable by anaerobic microorganisms, are further conducted directly through the first reactor, without substantial conversion, into the second reactor ((5) though a connecting conduit (4).  In the first reactor (2), the residenca time of only the slowly metabolizable pollutants is determined:to be sufficient 50 that the latter are degraded to low-molecular, dissolved fragments.  Subsequentlyl the dissolved fragments are introduced into the second reactor (S) together with the initially rapidly degradable pollutants.
