Abstract: Application for Patent of LLOYD F. HLAVKA for RF PICK-UP COIL CIRCUIT FOR A WIDE TUNING RANGE       NUCLEAR MAGNETIC RESONANCE PROBE     ABSTRACT OF THE DISCLOSURE    In a wide tuning range nuclear magnetic resonance spectro-meter, the probe structure includes a series resonant pick-up coil circuit disposed in RF magnetic field exchanging relation with the sample under analysis for detecting nuclear magnetic resonance of the sample.  A variable capacitor is series resonated with the inductance of the pick-up coil and the capacitor is arranged for tuning the series resonance of the pick-up coil over a wide tuning range, for example, from 6 to 32 megahertz.  The low series resonant impedance of the pick-up coil, as of 1.5 to 5 .OMEGA., is matched to the relatively high input impedance, as of 50 ohms, of a low noise RF amplifier by means of a pair of series connected transmission line transformers for transforming the 50 ohm input impedance of the amplifier to the low series resonance impedance of the pick-up coil.  The transmission line transformers are formed of two wire lines, one wire being connected in series with the pick-up coil and the other wire being arranged so that a current is induced to flow therein due to the distributed inductance and capacitance of the two wire line.  The induced current is added, at the low impedance end of the transformer, to the current flowing in the first wire, whereby a broadband impedance transformer is obtained.          Two such transformers are employed in series with the pick-up coil for transforming the low impedance of the coil to the relatively high input impedance of the preamplifier.  The transformers are broadband so that the impedance is well matched over the entire tuning range of 6 to 32 megahertz.

Abstract: ABSTRACT OF THE DISCLOSURE:          A machine for manufacturing paper, such as tissue paper, includes a twin-wire former made up of a rotary forming roll and a pair of endless fabrics, each of which may be a wire or felt, lapped around the rotary forming roll to provide twin-wire web formation therewith.  At the location where these endless fabrics travel beyond the forming roll they diverge from each other to define between themselves a diverging space where once of the endless fabrics has an upwardly directed surface on which the web is carried beyond the forming roll.  This latter endless fabric carries the web to a press section where this latter endless fabric travels with the web through a first press nip of the press section defined between an inner press roll situated within the loop of the latter endless fabric and an outer press roll situated outside of the latter loop.  This outer press roll is lapped by an additional endless fabric structure so that the web is situated at the first press nip between the latter addi-tional fabric structure and the endless fabric which carries the web away from the forming roll.  The web travels with the addi-tional fabric structure around the outer press roll, to become detached from the endless fabric which carries the web away from the forming roll, and this outer press roll cooperates with a drying cylinder of a drying section of the paper machine to define therewith at least a second press nip.

Abstract: BAG FILLING MACHINE FOR POWDERY MATERIAL                 Abstract of the Disclosure A machine is disclosed to bag powdery material wherein primary and secondary preconditioning chambers are used, having a volume sufficient to give enough time for the powdery material to become de-aerated.  This de-aerated powdery material is then supplied to a bulk filling station and a dribble filling station.  Bags spouted at the bulk filling station are filled to about 90 percent of their normal capacity and are then moved laterally to the dribble filling station whereat the bags are rapidly filled to a weight close to the desired exact weight and by automatic speed changing means filled to exact weight at a slower rate.  The bags are supported at the top by grippers at both filling stations with the calibrated weight scale being actuated by weight on the grippers at the dribble filling station.  An auger at the bulk filling station forces the powdery material down into a generally closed bag to force the bag open by the incoming material to thus keep air out of the bag as much as possible.  This saves time in the filling of the bags because time need not be spent waiting for the air to escape out of the powdery material in the bag before the bag can be closed and sealed.  A vacuum probe may be inserted into the bag while being filled to help this de-aeration.

Abstract: CURRENT TRANSFORMER              ABSTRACT OF THE DISCLOSURE A current transformer is encapsulated in an injec-tion molded layer of insulating material.  The current transformer includes a secondary terminal assembly having individual terminals mounted on a terminal board.  The terminal board is formed of a material that softens within the normal processing temperature range of the encapsulating material and forms an amalgamation therewith without a distinct interface between the terminal board and the encapsu-lating material which thereby provides a fluid-tight seal around the terminal assembly.  The individual terminals have an intermediate shoulder disposed adjacent the top surface of the terminal board to prevent the molding material from covering the terminal assembly during the injection molding operation and, further, to provide a sealing surface for the molding material around the terminal assembly.  A shorting bar is rotatably mounted between the terminals and rotates between a closed position shorting the terminals and an open non-shorting position.  A terminal cover interlocks with the shorting bar to prevent improper positioning of the shorting bar.

Abstract: ABSTRACT OF THE DISCLOSURE This application discloses a cuvette cartridge which is adapted for use with an analyzer apparatus.  The disposable, substantially rigid cartridge includes a chamber and a plurality of cuvettes disposed adjacent the chamber. The cartridge has no secondary air escape means.  An opening is located between the chamber and each cuvette.  The cuvettes are preferably filled by a series of pressurizing steps in which pressure is exerted on fluid in the chamber and fluid from the chamber is forced into the cuvettes.  The air pressure in the cuvettes and chamber is then equalized, after which the chamber is again pressurized and fluid is again forced into the cuvettes.  The filling operation is repeated until the cuvettes are uniformly filled to the de-sired level.  The cuvette filling operation occurs in essentially a closed system so that the air in the cuvettes is not permitted to escape during a filling operation.

Abstract: ABSTRACT OF THE DISCLOSURE           An airbrush of the double action type has an elongated unitary body having an axial passage for longi-tudinal movement of a needle supported therein.  The rear end of the needle is carried by a guide slidably supported in the axial passage and normally urged by a spring in a direction such that the tapered front of the needle enters and closes the jet.  A finger-operated lever formed of plastic and shaped to provide a "living hinge" is supported in the body and arranged to engage the guide and move the needle against the action of the spring to control paint flow, and at the same time to open a valve to allow entry of compressed air or other substance under pressure.  The maximum paint flow at the fully-operated position of the control lever is predeter-mined by adjusting the longitudinal position on the body of a closure cap which limits the movement of the guide.          The airbrush has a minimum number of easily assembled parts and features a relatively simple paint-to-air seal disposed within the axial passageway.

Abstract: ABSTRACT OF THE DISCLOSURE         A diamond pattern of holes or depressions is formed in a plastics material sheet.  The holes are in rows across the sheet, the holes of adjacent rows being staggered.  The distance apart of adjacent holes in a row is at least 1.5 times the distance apart of adjacent, aligned holes in the direction at right angles to the rows.  The sheet is then stretched in a stretch direction at right angles to the rows.  The zones be-tween adjacent holes in a diagonal sense form orientated strands and the zones between adjacent holes in each row form junctions which have their lateral  zones orientated but a central zone which is unorientated or less orientated.  The new structure so formed is useful because there is a continuous line of orien-tation running through the structure generally in the stretch direction, making the structure less liable to tear under shock loads.
