Abstract: ABSTRACT OF THE DISCLOSURE   Shaped pharmaceutical tablets and other solid oral dosage unit forms which have a prolonged homogenous release pattern of active medicament over a period of hours wherein each shaped tablet or dosage unit comprises a carrier material base of hydroxypropylmethylcellulose with or without a proportion up to 20% of ethylcellulose and wherein the carrier material base is specially processed under controlled conditions of moisture, temperature and time, and then compressed at relatively low compression pressure with an incorporated active medicament.  The compressed dosage units or tablets when orally administered give a continuous incremental release of the active medication without initial peaking and/or super or sub-therapeutic dosing.  This provides effective blood levels free from any toxicity due to the carrier material which is chemically inert, of decreased solubility and enhanced stability, due to its processing and to the inclusion of a stabilizing agent.

Abstract: ABSTRACT         A demand limiting system is provided for a large electrical energy customer with at least one modulating load.  A master control unit continually compares the actual power usage to the desired rate of power usage.  When the desired power consumption rate is exceeded by a first amount, the master provides a hold signal to an associated slave control unit, which prevents further loading of the modulating load.  When the desired rate of power consumption is exceeded by a second amount, the master provides a reduce signal to the slave unit, which begins to reduce the load.          While the hold signal is calling for a reduced load, only a fraction of the time is utilized to reduce the load, and the remainder of the time the modulating load is in the hold condition, allowing the system to stabilize and prevent hunting.  The reduce signal also regulates load shedding equipment, to disconnect non-critical loads.  A safety and alarm circuit provides various audible indications and/or shut-down operations responsive to detection of various fault conditions.

Abstract: ABSTRACT            In a process according to the present invention uranium is extracted into solution form its ore by leaching with an aqueous solution containing peroxomonosulphuric acid, the peroxoacid oxidising the uranium through to its hexavalent state.  Preferably the leaching is carried out at a temperature in the range of 50 to 100°C.  The leach liquor can initially contain additional amounts of sulphuric acid or merely that present by virtue of the method of making the peroxomonosulphuric acid.  In a preferred method of operation, the peroxoacid is introduced progressively into the leach liquor during the course of the leaching so as to maintain an electrochemical potential in the range of 450 to 650 mV.            By use of the process, uranium is cleanly extracted into solution.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and method for monitoring the quality and integrity of a communications system, such as a cable television system, which includes several monitoring circuits placed throughout the system to detect and amplify RF or audio frequen-cy signals received at any number of selected points.  The de-tected signals are used to amplitude modulate a continuous wave oscillator at a selected one of several discrete frequencies identifiable with the position of the monitoring circuits.  The modulated CW signals are then fed upstream for processing at a central location.  Each monitoring network includes a broadband detector so as to enable the detection of one or more discrete frequency signals or a band of signals.  The use of several dis-crete frequency signals for normal monitoring purposes allows reliable monitoring to be carried out on a continuous basis with-out causing interference to the information signals being trans-mitted through the system.  If a fault or deviation is detected, a swept band of signals can be fed into the system whereupon the monitor circuits will detect the entire band and return to the central point a full frequency response pattern to facilitate detailed analysis.
