Abstract: METHOD FOR CONVERTING INTERMITTENT TO CONSTANT                 REFUSE FLOW                         ABSTRACT     Method for providing surge capacity and for smoothing out the flow rate of refuse in a system, wherein refuse is loaded onto a moving conveyor at variable or intermittent rates, by (1) preventing excess refuse from passing beyond a given point on the conveyor by a rotating leveler, spaced a predetermined distance from the conveyor to permit only the desired level of refuse to remain on the conveyor beyond the leveler, and (2) rotating the leveler at a speed greater than the speed of the conveyor, the direction of rotation of the leveler being opposite to the direction of travel of the refuse on the conveyor.  Refuse in excess of the amount desired to be transported by the conveyor is retained behind the leveler as a rolling inven-tory of refuse, causing the refuse to be discharged from the conveyor at a constant and uniform rate.

Abstract: ABSTRACT OF THE DISCLOSURE        Circuit operating from a direct current source applies DC pulses to a high pressure sodium vapor lamp to improve the color properties of the lamp.  The circuit includes a controlled thyris-tor switch in series with the lamp, an RC timing circuit for periodically turning on the switch at predetermined intervals, and an LC circuit for turning the switch off.  An inductor comprising the primary winding of a transformer in series with a diode across the capacitor of the LC circuit provides for discharge of the capacitor to enable subsequent re-charging thereof, so as to produce the desired pulsed operation of the circuit, and the trans-former secondary winding in series with a diode clamps the voltage of the primary winding.  The disclosed arrangement prevents exces-sive voltage across the controlled switch and provides for the control of lamp wattage with respect to changes in lamp voltage.

Abstract: ENVIRONMENTAL CONTROL OF A BUSHING BY HORIZONTAL STREAM OF CASEOUS FLUID              Abstract of the Disclosure A method and apparatus for forming glass fibers is disclosed.  The method of the present invention involves passing a narrow, high velocity air stream horizontally below the bushing to thereby induce and entrain additional air flow from the environment surrounding the bushing into this air stream to flow generally horizontally below the bushing.  Suitable apparatus, such as an air amplifier, is employed to produce this desired result.  By this means the environment in the fibre forming region below the bushing can be controlled to suppress variations in temperature and/or air flow in the region.

Abstract: ABSTRACT OF THE DISCLOSURE   According to the present invention, there is provided apparatus for use in measuring by infrared absorption measurement the content of CO2 in respiratory gas.  The apparatus comprises a holder for receiving a tube for conducting a cyclical respiratory gas flow, heating means in the holder for maintaining the tube at a substantially constant temperature, receiving means for receiving an infrared source, a lens system, a narrow-band interference filter suited to CO2 and a detector for irradiation by the infrared source via the gas flow.  The receiving means, the system, the filter and the detec-tor are carried by the holder and aligned with each other. The advantages obtained with this construction consist in that, because of the small dimen-sions which are possible, the apparatus can easily be connected in the respira-tory circuit at a short distance after the mouthpiece without any trouble to the patient.  The tube can easily be interchanged and thus meets a sterili-sation requirement which is unavoidable for medical equipment.  Either it can be sterilised after being taken out, or it can be replaced by a new tube.  The tube is simple in construction, need not contain any other devices necessary for operation, and thus is inexpensive.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention is a tubing tester adapted to be coupled between a string of tubing and a well bore packer.  An outer sleeve is coupled at one end to a string of tubing.  A cylindrical mandrel is slidably and rotatably positioned in the other end of the outer sleeve.        Advancing or retracting movement of the mandrel is affor-ded by rotating the sleeve so that lugs on the sleeve engage grooves in the periphery of the mandrel to move the mandrel axially with respect to the outer sleeve.          An inner sleeve is locked in position within the outer sleeve and has a spring loaded flapper valve at an end facing the mandrel.  Advancing movement of the mandrel forces a curved end thereof against the flapper valve to urge the flapper valve to a fully open position to extend into a cut out wall portion in the inner sleeve.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus and a method for lenticulating a first of two films and for laminating the two films together. The lenticulating of the first film can be done before or after the lamination of the two films.  If the lenticulation is done before the lamination, the first film is pressed against a lenticulating drum to form lenticulations in one face of the film.  Then the first film is moved into contact with the second film after the second film has been coated on one face with a flowable cement so that the films are bonded together to form a composite film.  The second film has a photographic emulsion on the face opposite to the face bonded to the first film.  After lamination, the composite film is moved along a path whose length is sufficient to permit drying of the cement before the composite film is wound on a take-up roll.  The first film is typically cellulose acetate and the second film has a polyester base.

Abstract: Case 7-11491/GTN 434 Code Translator Abstract of the Disclosure Means for converting characters of a first 128-character alphabet (ASCII) into characters of a second 26-character alphabet are provided and convert each pair of characters of the first alphabet into three characters of the second alphabet and vice versa.        The means are embodied by a suitably programmed computer. In the conversion, each pair of characters Z1, Z2 of the first alphabet are interpreted as numbers and divided by 26.  The resulting largest multiples Q1, Q2 of 26 are multiplied by 1 and 5 respectively and the products are added.  The remainders after division give the first two characters A1 and A2 out of each set of three characters of the second alphabet, and the sum of the products gives the third character A3.  Reconversion is similar.  First, Q2 is obtained by division as the largest integral multiple of 5 in A3 and Q1 is the remainder after division.   Q1 and Q2 are then each multiplied by 26 and added to Al and A2, giving the sums Z1 and Z2.
