Abstract: SAFETY SUPPORT FOR HARVESTER COMBINE FEEDERS                 ABSTRACT OF THE DISCLOSURE         A safety support for maintaining the feeder of a harvester combine, together with its associated header, in an elevated position in case of failure of the usual lift cylinder.  A telescopic brace has its forward end pivoted to the feeder and, when in a predetermined extended operative condition, has facilities at its rear end whereby it is supported on the front axle housing of the combine so that it may function under compression to assimilate the weight of the feeder and maintain the latter elevated.  In a collapsed inoperative position the brace closely underlies the bottom wall of the feeder in a stored position and is held in such position by a suspension bracket which supports the rear end of the brace.  A single anchor pin cooperates with the brace to maintain the latter in its extended position and also cooperates with the suspension bracket to maintain the rear end of the collapsed brace in an elevated position.

Abstract: ABSTRACT OF THE INVENTION A vacuum return ink system for an ink jet printing apparatus includes an ink/air separator compri-sing a housing having a chamber formed therein.  A first inlet port of relatively large diameter connect the chamber via a short tube of similar diameter to the ink catcher of the printing apparatus used for accumulating unused ink.  A second port of relatively large diameter is provided to connect the chamber via a tube of a simi-lar diameter to a vacuum source.  A third port of rela-tively small diameter is provided to connect the chamber via a tube of similar diameter to an evacuated ink return tank.  A tubular section defining the third port is inserted into the housing with the end thereof extending to the floor of the chamber.  Ink and air are drawn from the catcher into the chamber via the first port at a high rate of flow, thereby minimizing a buildup of ink at the catcher mouth.  The ink having a higher inertial mass than the air is carried by gravity to the chamber floor where it is drawn into the small diameter tubular section and carried at a relatively low flow rate to the evacuated ink return tank, thereby minimizing solvent evaporation of the ink.  The air flowing into the chamber from the catcher is carried therefrom to the vacuum source via the second port.

Abstract: FLUORESCENT LAMP WITH AN INTEGRAL FAIL-SAFE AND AUXILIARY-AMALGAM COMPONENT     ABSTRACT OF THE DISCLOSURE         Fast "warm-up" of an amalgam-regulated fluorescent lamp under "cold" starting conditions and safe failure of the lamp at the end of its useful life are achieved by coating selected portions of both stems with a material that contains indium or an indium alloy and initially is semi-conductive.  The coating is applied to portions of the stems adjacent the electrodes and covers a segment of one or both of the lead wires at the point where they emerge from the stem presses.  The coating is thus rapidly heated and releases mercury vapor as soon as the lamp is energized.  When the electrodes are devoid of emission material and the lamp has reached the end of its useful life, sputtered material from the metal parts of the mount renders the coating electrically conductive and causes the arc to impinge upon and finally puncture the stem.  The coating accordingly serves both as an auxiliary-amalgam source and a "fail-safe" component Coatings of materials that are electrically conductive as soon as applied and contain an amalgamative metal can also be used, providing they do not contact both leads.

Abstract: ABSTRACT OF THE DISCLOSURE                Apparatus and method is disclosed for loading a plurality of bales or containers containing pouches filled with a liquid such as milk into a rectangular open-top case. An empty case is located in the apparatus and a rotatable compartment means is positioned above the case and defines suitable bale-receiving compartments.  The bales are fed via a conveyor to a position overlying an empty compartment so that the bale falls into the compartment.  The compartment means then rotates to bring another empty compartment into registry with the conveyor.  This repeats until the case is full, at which time a trap door below the compartment means opens to permit the bales to fall into the case and the full case is then withdrawn from the apparatus.          An empty case is brought to a position below the empty compart-ment means and the filling process is repeated.  The case has been filled symmetrically and is easy to handle thereafter.

Abstract: ABSTRACT        Apparatus for use in controllably injecting contaminant material into a liquid flowing through a conduit in a liquid flow system.  The apparatus has a reservoir section and an injection section with a central section optionally provided for interposing between the reservoir section and the injection section when low and/or slow rates of injection are desired.  The reservoir section is a graduated tubular member having a detachable cap with an adjustable pressure relief valve mounted therein.      The reservoir chamber merges, at the opposite end, into a truncated conically shaped portion in a body detachably mountable on the injection section or intermediate section, as the case may be.  When mounted on the injection section, the reservoir chamber communicates with a passage in the injection section that gradually decreases in cross-sectional area toward a restricted opening communicating with a flow passage through the injection section and which flow passage is connectable in line with the conduit of the fluid flow system.  An adjustable valve is provided for varying the rate of flow through the restricted discharge outlet.  A   passage is provided for supply a pressurized fluid to the passage adjacent, but upstream from, the flow control valve to pressurize the reservoir chamber and mix contaminant therein with liquid in  the reservoir.      The central section provides an intermediate chamber between the reservoir chamber and the injection section and is in communication with the reservoir chamber through an adjustable flow contro valve.
