Abstract: CEMENT SLURRY RECLAMATION SYSTEM AND METHOD           Abstract of the Disclosure A slurry reclamation system for use with a concrete ready-mix plant which enables 100% reclamation of the constituents of concrete mix returned to the plant site by vehicles.     Returned concrete mix is dumped into an inlet hopper having a screw classifier for removing aggregate and coarse sand, and a weired channel enabling gravity flow of the water, cement fines and sand fines constituents into a slurry vessel.  The slurry in the vessel naturally separates into clarified water and concentrated slurry, and agitators are provided for periodically stirring up the slurry to maintain the cement fines active.  The slurry vessel is sized in such a manner as to guarantee complete consumption of slurry returned during a day's production by the end of the following production day, the volumetric capacity of the vessel being related to the total average volume of water used to produce fresh concrete during a repre-sentativ e production day.     An autochangeover unit automatically switches the water supply to truck washout stations and the screw classifier between normal plant supply water and the clarified water in the vessel, depending upon the level of the latter.     The system enables substitution of slurry for cement fines alone, and alone, water alone, or any combination of these concrete constituents in accordance with the percent activity of the cement fines in the slurry and production demand.

Abstract: RECORDED IMAGE DETECTION SYSTEM     FOR UPDATABLE MICROFILM              ABSTRACT OF THE DISCLOSURE    The present invention is used in photo-recording machines, such as microfiche recorders, which receive a document and record an image of the document of a photo-recording medium such as photoplastic film.  The invention inhibits double exposures on frames of the film by use of distinctive indica-tor marks recorded on the film at preselected locations called indicator mark fields.  The presence or absence of an indicator mark in such an indicator mark field signifies, respectively, that its corresponding frame is or is not available for recording a document image.  In an improved recorder, prior to a proposed recording, a detector scans the indicator mark field corresponding to the frame selected for recording.  If the detector detects an indicator mark, the recorder is inhibited from recording the document in the selected frame.  A projection light source forms the image of the indicator mark field and projects it along an optical path in which a sensor of the detector is interposed.  Where the indicator mark includes lighter and darker portions, the sensor responds to the intensity variations and may be mounted on motive means and swept thereby across the optical path transversely.  The sensor output is automatically evaluated by means which may include or cooperate with a logic circuit responding to an evaluation signal and preventing recording despite an operator-entered record instruction.          If no indicator mark is detected, document recording proceeds in the selected frame, and an indicator mark is simultaneously recorded in the corresponding indicator mark field.

Abstract: METHOD OF AND APPARATUS FOR REGENERATING              A SIGNAL FREQUENCY IN A DIGITAL SIGNAL              TRANSMISSION SYSTEM           Abstract of the Disclosure In a digital signal transmission system, digital signals at a first frequency are synchronized to a second, slightly higher, frequency for transmission in frames and superframes, positive stuffing being effected one frame at a time at a slow rate.  At the receiver, the received signals, but not stuffed frames, are written into a memory and the signals are read from the memory at the first frequency.  The first frequency at the receiver is generated using an oscillator whose frequency is controlled in dependence upon a comparison of the relative phases of writing into and reading from the memory.  The digital signals at the first frequency are derived from an incoming bit stream having a frequency which is higher than the first and second frequencies, by omitting synchronizing bits from the incoming bit stream.     - i -

Abstract: ABSTRACT        A system is disclosed for demand-based administration of insulin which utilizes a change in a physical property of a patient's body fluid as an indicator that a change in the body fluid glucose level has occurred and that an appropriate amount of insulin should be supplied to the patient.  Body fluid osmolality or one of its colligative properties are particularly suitable for this purpose.  A second sensor for measuring such properties as electrical conductivity may be added to detect changes in osmolality caused by such factors as dehydration. Insulin can be delivered to the patient from an extracorporeal source by means of a dual lumen catheter.  One lumen of the catheter provides a passageway for the insulin dose and the other lumen provides a passageway through which a replaceable sensors can be introduced into or removed from the patient's body.  In the alternative, the entire insulin administration system can be implanted into the patient.

Abstract: ABSTRACT OF THE DISCLOSURE     A time code correction circuit is formed of an input circuit for receiving an input time code; first and second memories for storing data representing the time code; an adder for selectively incrementing or decrementing data to be supplied to the first and second memories; a comparator comparing the data stored in the first memory with the input time code; a switch controlled by the comparator for selectively supplying the adder with the input time code and the data started second memory; and an output circuit coupled to provide the contents of the second memory as a corrected output time code.  Where the time code is reproduced from a time code track recorded on a magnetic tape, the correction circuit is favorably adapted to produce a continuous time code sequence despite dropout in the recorded time code. Also, if a jump occurs in the recorded time code sequence, the correction circuit causes the output time code to reflect such jump with a minimum of signal disturbance.
