Abstract: The patient positioning device of this invention relates to an apparatus used to assist a patient into a supine position and additionally through which traction is applied to the spine, such as physical therapy and chiropractic treatment. The patient positioning device is preferably a stand alone portable device that can be readily transported and adapted to almost any horizontal surface, such as a treatment table. A primary application of the leg support of this invention is in raising and supporting a patient's lower legs during before, during, and after traction is applied to a patient. The device includes a lower support frame, vertical supports, and a leg support coupled to a top frame. The patient positioning device may also have a motor which powers the leg support to rotate from a lowered position, in which a patient's lower legs rest on the leg support, to an elevated position in which a patient's lower legs are elevated.

Abstract: An apparatus and method for providing liquid and gas proof sealing between a metal rod and a plastic housing molded there around. The rod includes a plurality of annular intrusions or protrusions along a length thereof. The plastic material is formed around the rod and the annular intrusions or protrusions. After the plastic material has cooled the rod is translated linearly with respect thereto whereby the annular intrusions or protrusions cause a cold flow movement or disruption of the plastic material. This movement results in a liquid and gas tight sealing between the rod and the plastic housing. The invention herein has particular application for liquid level sensing probes located within gas pressurized vessels. In such examples the rod or rods are used for sensing liquid level by means of electrical conductivity with the sensed liquid.

Abstract: A multicompartment photoelectrodialytic demineralization cell is provided with a buffer compartment interposed between the product compartment and a compartment containing an electrolyte solution. Semipermeable membranes separate the buffer compartment from the product and electrolyte compartments. The buffer compartment is flushed to prevent leakage of the electrolyte compartment from entering the product compartment.

Abstract: Differential length parallel lift arms have means at one end for attachment to a belly mounted tractor appliance. At their opposite ends the lift arms are adapted to be pivotally mounted on a common axis on a tractor under which the appliance is adapted to be located. Lift arm actuating means are connected to the lift arms for effecting substantially parallel lifting of the appliance by the arms. Means for effecting operation of the actuating means may be operated hydraulically or otherwise from the tractor seat.

Abstract: An improved plant support structure formed of relatively rigid, bent steel wire. In one form, the plant support comprises a plurality of wire elements each formed into a plurality of diamond-shaped segments with each element mutually interconnectable to a like element by means of a plurality of rigid, frictional, releasable wire interconnections. In an alternate form, the plant support of the present invention is formed of a longitudinal wire fabric web comprising a single strand of wire formed into a plurality of mutually interconnected transverse strand segments each bent into a zig-zag shape and interconnected to the next adjacent strand segment by means of frictional twisted wire connections. The plant support structure may be open fence-like trellis structures or closed substantially cylindrical structures.
