Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for hydraulic self-leveling of a loader bucket or the like is described wherein the loader upon which the bucket is mounted comprises a pair of spaced-apart boom arms pivotally mounted on a sub-frame attached to the tractor.  The boom arms are pivotally moved relative to the tractor by means of hydraulic cylinders connected thereto.  The loader bucket is pivotally connected to the forward ends of the boom arms and may be pivotally moved from a level position to an extreme dump posi-tion or an extreme roll-back position by means of hydraulic cylinders extending between the loader bucket and the boom arms. A first leveling cylinder or actuator cylinder is connected to one of the boom arms and one of the sub-frame towers so that upward movement of the boom arms causes the cylinder rod of the actuator cylinder to be extended therefrom and so that downward movement of the boom arms causes the cylinder rod of the actuator cylinder to be moved inwardly into the cylinder.  Extension of the cylinder rod from the actuator cylinder forces fluid from the actuator cylinder to be supplied to the extension side of the bucket cylinders so that the bucket is maintained in a level position as the boom arms are being raised.  Conversely, retraction of the cylinder rod into the actuator cylinder as the boom arms are being pivotally moved downwardly causes hydraulic fluid from the actuator cylinder to be supplied to the retraction side of the bucket cylinders to maintain the bucket in a level position as the boom arms are being lowered.  The actuator cylinder includes a pressure relief valve assembly in the piston thereof to permit hydraulic fluid to flow from one compartment portion to another upon the pressure in that particular compartment portion reaching a predetermined level.  A second leveling cylinder or actuator cylinder may be mounted on the other boom arm and tower if so desired.

Abstract: PACKAGE FORMING MACHINE               ABSTRACT OF THE DISCLOSURE         A package forming machine wherein one or more articles are packaged as a unit by the wrapping of a film of shrinkable plastics material thereabout, the film being provided as a continuous web.  The machine is adapted to the packaging of plural articles arranged in a plurality of rows.  The machine receives articles in nested rows and is provided with means for automatically bringing adjacent articles into transverse alignment.  The articles are then moved in clusters to a wrapping station where a continuous film is engaged over the top of each cluster and held in-place by an upper conveyor while at the same time the cluster is being engaged by and supported by a lower con-veyor which moves in unison with the upper conveyor.  Film drawing means then moves down between each pair of adjacent clusters and draws the necessary film, after which the film is severed into individual wraps followed by the directing of a rear bottom flap into underlying relation with respect to the rear part of the cluster.  Thereafter, the partially wrapped cluster is moved onto a platform wherein the front flap is both tightly drawn with respect to the cluster and positioned beneath the cluster and the rear flap.  The machine also includes spacer means movable in between par-tially wrapped adjacent clusters to stabilize and maintain the spacing thereof.

Abstract: ABSTRACT OF THE DISCLOSURE     A manual torch for tig welding is disclosed which has an adjustable head which can be orientated at various angles relative to the handle.  The torch includes conduits for both cooling fluid as well as the inert gas and the conduits are defined within the pivoting connection of the torch.  The manual torch comprises an insulated handle, a head fastened to one side of the handle and provided with an insulated casing, with the head having a forward portion comprising a first stationary flank and a second removable flank and a rear portion to which the cooling fluid conduit and the insert gas conduit are attached.  A rotatable block arranged between the first and second flanks is provided and has a recess for the flow of inert protective gas connected to the inert gas conduit.   A carrier, which can be orientated, is provided bearing an electrode and supported by the block.  The carrier has a circular recess provided around the electrode and connects the recess of the rotatable block.   A ceramic nozzle surrounds the electrode and a pivot pin is provided on each side of the rotatable block to rotatably support it on the stationary and removable flank.  This allows rotation of the rotatable block to a desired inclination angle of the electrode and the supply of electrical current thereto.  An insulating ring partially surrounds the rotatable block and allows its rotation within the maximum inclination range to avoid dispersion of high frequency arc ignition currents.  Such a torch reduces the dispersion of high ignition arc currents and minimizes the possibility of rupture of the conduits.

Abstract: Abstract A vacuum operated sewage system includes a static pressure sensor establishing a trigger signal at a selected first level in a standpipe.  The sensor is connected upstream of a discharge control valve and actuates a trigger and timer controller at the selected sensed pressure to establish flow for a predetermined period.  A separate air admission control is provided to separately actuate the timer controller if the vacuum level in the sewage flow line drops below a selected level, to thereby reset the system vacuum pressure.  The air admission control includes a level trigger valve operable to actuate the controller.  A by-pass pressure sensing valve has an input connected to sense line pressure and holds the trigger valve in standby until the line pressure drops below a selected vacuum pressure. A resettable fluid timer is also connected to the level trigger valve and is charged under normal pressure system conditions.  The timer holds the trigger valve in the set state for a selected period after the by-pass sensing valve responds to system level pressure decreasing below the selected minimum operating pressure and thereby prevents response to momentary changes in the flow line vacuum level.
