Abstract: In a high pressure spray cleaning apparatus and method there is provided separate pressurized flow circuits to separate inlets of a spray head. A chemical flow circuit delivers a cleaning chemical fluid under pressure and a carrier flow circuit delivers a heated carrier fluid, preferably water and or soap, under a relatively high pressure. The pressurized cleaning chemical fluid and heated water are intimately mixed and distributed by a novel spray head. A power-driven air compressor is coupled to a chemical storage tank containing a cleaning chemical in the chemical flow circuit. A power-driven positive displacement pump associated with a by-pass unloader valve regulates the pressure of the water from a water tank delivered to a heating coil in which the water is heated in the carrier flow circuit. When the heated water is not being sprayed at the spray head, it is automatically returned by the operation of the by-pass unloader valve at a reduced pressure to the water tank.

Abstract: Packaging apparatus for closing and sealing the open end of a carton of thermoplastic coated paperboard material or the like. A rotatable drum has a cylindrical wall that supports a plurality of carton closing and sealing units. During rotation of the drum, open ended cartons are successively picked-up at a carton receiving station and are carried by the drum to a carton delivery station. During the movement of the carton from the receiving to the delivery station, the open end of the carton is folded to a closed condition and the layers of the closed carton end are vibration welded together by one of the carton closing and sealing units. Each carton closing and sealing unit includes a pair of jaws movable between an open and closed position with respect to each other, a latching member for locking the jaws in their closed position, and a vibration welding device.

The support frame also carries a plurality of guide and drive rollers which are engageable with the object to be embedded and which engage the object to move the support frame along the object as the drive track advances along the water bottom. A bottom trenching device in the form of a ground mill with a rotatable cutting head is pivotally mounted on a support between the drive rollers and the drive track and it operates on the bottom to remove material therefrom to form a trench. The material may be subsequently directed backwardly over the object to be embedded after it is positioned in the trench.

The device includes a front carriage and a rear carriage. One approaching initiator each is provided on that portion of the front carriage which faces the rear carriage, and the arrangement is such that when turning the steering wheel and when the front carriage angularly approaches the rear carriage, a pertaining thyristor is triggered so that a magnetic valve is energized which through hydraulic control conduits communicates with the tank.

Abstract: Disclosed is a dispenser of the type having a suspended, upwardly biased, carrier plate for holding trays, plates, etc. and for automatically advancing the load of articles to present the uppermost article at a predetermined position near the open top of the dispenser. The dispenser has an improved biasing system for achieving the automatic advancement of the load employing compression or tension springs as the biasing means and a deformer supported for vertical movement with the carrier plate and for horizontal movement relative to the carrier plate so that it can bear upon the biasing means to cause deformation thereof. A cam member is obliquely supported on the frame within which the carrier moves and horizontally deflects the deformer as the carrier tray is depressed. Thus, the further the carrier plate is depressed (e.g.

Abstract: Porous, tubular core sections coated with a semipermeable membrane are joined at their ends by a simplified coupling member. Each coupling member or connector comprises a cylindrical flange member having helically ribbed or barbed nipples which fit tightly into the ends of bores of adjacent core sections. The ends of the cores abut against the circular part of the coupling member. The ribs on the nipples on the coupling member are resilient and deform when inserted. The nipples have neck parts of a smaller diameter adjacent the body part of the coupling member providing annular spaces between these neck parts and the bores of core members permitting continuous flow of permeate and cleaning solution into these spaces and helically along the nipples. There are no appendages, cavities or pockets in which permeate or cleaning solution could be trapped.

Abstract: Attachment for securing an electric heating element and a thermostat to a water heater. An external fitting is welded around an opening in a water heater tank through which the heating element extends and is secured to oppositely disposed flanges on the outer portion of the fitting by a selectively rotatable latching cap which has ears on the inside which engage the inner portion of the respective flanges of the fitting. A bracket engages the thermostat at the upper end and has a pair of spaced arms at the lower end extending along each side of the fitting with an upstanding abutment on each arm which engages the underside of the flanges of the fitting to hold the bracket and the thermostat against the tank wall. A second upstanding abutment of greater height than the first abutments is located between the first mentioned abutments and engages the fitting flanges to prevent rotation of the bracket.

Abstract: The nozzle manifold assembly of an injection molding machine is infinitely adjustable horizontally perpendicular to the nozzle axis. The nozzles themselves project through slots in the front clamp plate of the machine which give flexibility to the mold designer in his placement of sprues and runners for filling the mold. Additionally this manifold assembly and its associated injection hardware, such as the shot accumulator, hydraulic pressure accumulator and valving, are mounted on a carriage assembly which is capable of moving horizontally in a direction parallel to the axis of the nozzles thereby allowing the nozzles and associated heater bands to be accessed and maintained without the need for removing the mold from the machine.
