Abstract: ABSTRACT           For use with banding apparatus for putting bands, especially those of plastics banding, around a pallet and its load, a band feed guide for threading banding through the voids between the deck and runners of the pallet.  The band feed guide is made up of tapering channel chute sections comprising primary chute sections which telescope with secondary chute sections and are extended axially into the voids when the pallet is at the apparatus to form with the secondary chute sections a continuous band feed guide below the deck of the pallet. In the telescoping condition the chute sections can be swung down below the level of the runners while the pallet is moved.                           .1.

Abstract: ABSTRACT        The forward frame portion of a farm tractor is provided with a first and a second equipment accommodating mounting location so that the basic underhood equipment can be mounted in one of two configurations.  The first con-figuration is generally adapted for a two wheel drive tractor where the engine is conventionally mounted between the front and rear axles of the tractor, the radiator is forward of the engine and an air cleaner is forward of the radiator.  A second configuration is adapted for use with a driven front axle thus providing a four wheel drive tractor.  In this configuration the engine is located generally above the front axle, the radiator is rearward of the engine and the air cleaner is rearward of the radiator.  In either of the con-figurations only one of the mounting locations is utilized while the other is unutilized.

Abstract: PULSE CONTROLLED POTENTIOMETER                ABSTRACT OF THE DISCLOSURE     A plurality of resistors are series coupled with the free ends forming the end points of the potentiometer.  A plurality of electronic switches have each of their inputs coupled to a predetermined point in the resistor array.  The output from the switches are connected in common, thus forming the tap to the potentiometer.  Activation of the switches is determined by control logic comprising an up/down counter, the outputs from which couple to the switches, an astable multivibrator for incrementing the counter and gating circuitry for selectively coupling the astable to the counter.  The control logic is arranged to respond to received command signals for causing the tap to sequentially increment towards either end of the pot and to stop incrementing at a desired point.  Further, the control logic causes the sequential tap incrementing to reverse once the tap reaches either end point of the pot.

Abstract: AN IMPROVED PASSIVE OPTICAL RANGE         SIMULATOR DEVICE             ABSTRACT OF THE DISCLOSURE            An improved passive optical range simulator device which can be used to test the ranging function of an optical radar ranger system having parallel beams leaving and entering.  An adapter member provides for mechanical coupling and optical alignment of the simulator device with the ranger system.  A focusing lens transforms parallel beams entering and leaving the ranger system into focused beams entering and leaving one end of a coil of optical fiber having a mirror at its opposite end to act as an optical delay medium.  A primary tilted-glass-element optical attenuator limits optical energy allowed to reach the optical fiber entrance face, while deflecting first surface reflection away from ranger system input.  A removable attenuator assembly having oppositely-tilted flat glass elements at the fiber entrance face permits, by substitution, fine adjustment of beam attenuation.  An X-Y-Z translation assembly for the fiber entrance face, together with a light source at the opposite end of the fiber, provides for proper alignment with the focused beams.

Abstract: A B S T R A C T         The present invention resides in the area of corrosion inhibition in gas conditioning where CO2 and small amounts of H2S are removed by an absorbent.         The invention is an inhibitor composition for alkanolamine solutions and other absorbents for removing CO2 and small amounts of H2S from gas streams, comprising an inhibiting concentration in the absorbent of a combination of one part by weight of a quarternary pyridinium salt and either (1) 0.001-10 parts of a thio compound which is a water-soluble thiocyanate, a water-soluble sulfide, or an organic thioamide, or (2) 0.01-10 parts of a lower alkylene-polyamine, a corresponding polyalkylenepolyamine or mixture thereof, wherein the alkylene units contain 2-3 carbon atoms.   The advantages obtained over the prior art are less corrosion than results from numerous known inhibitor combinations, and the claimed inhibitor systems are essentially non-toxic, in contrast with previous inhibitor systems using arsenic, antimony or vanadium.

Abstract: ABSTRACT OF THE DISCLOSURE An infrared gas analyser capable of eliminating the effects of an interference component in a sample gas and reducing errors resulting from ambient temperature fluctuation is disclosed.  The analyser includes a sample cell filled with sample gas, a first filter which transmits infrared rays of a fixed band included within the absorption wavelength band of a measurement component.  A temperature compensating cell encloses a gas which has part of its absorption band within the transmission band of the first filter and different in spectrum from the measurement component.  Also pro-vided are an interference cell enclosing a gas containing a measurement component of fixed density and an interference compensating cell filled with the sample gas.  A second filter transmits infrared in a band which includes the major path of the transmission band of the first filter.  Two light paths from an infrared source to a detector are formed, one through the temperature compensation cell the sample cell and the first filter and the other through the interference cell, interference compensating cell and the second filter.  Each path carries half the total light.

Abstract: ABSTRACT OF THE DISCLOSURE             A patch module assembly consists of a two piece frame structure, which provides three parallel jack receptacles entering the frame through one end for receiving patch cord wand. The sides of the frame are closed by printed circuit boards which are electrically connected through plug connectors through the other end wall. The circuit boards support T-Bar*type switch wafers whose normally closed switches are in series in the various printed circuits between connectors. The printed circuitry also connects spring contacts at one of the wand support receptacles to one side of one of the switches. Another wand sup-port receptacles has spring contacts connected to the opposite side of the switches. A third wand support receptacle has spring contacts connected to either one side or the other of the switches. The contacts of the respective receptacles mate with contacts on an insertable wand, which en-able patch connection to other circuits, Placing  the wand in the first or second receptacle causes an actuator to disconnect the series switches after which one side or the other of each series switch is connected to some remote circuit. The third receptacle does not disconnected to series switches but makes a connection to the line through each series switch to serve as a voltage monitoring device, or the like. In the first two receptacles, the nose of the wand engages a different can surface of the same actuation lever, which moves against an actuation plunger of he series switch wafer opening the normally closed contacts. The wand is a split cylindrical structure of hollow form, internal portions of which provide two oppositely directed contact assemblies. The contact assemblies can be preassembled and prewired before assembling the wands. In the assembly of the two halves of the cylindrical wand, insulator bases opposed to each other urge the contacts outwardly through holes along diametrically opposite sides of the wand positioned to engage the respective spring fingers.
