Abstract: Apparatus for monitoring the resistance of the return part of the patient circuit of either a dual foil or single foil return electrode according to a user's selection is disclosed. The apparatus measures the quality of the contact between the return electrode and the patient. A DC or AC converter provides a substantially DC voltage at its input that varies in relation to the resistance of the return part of the patient circuit at its AC output. Preferably, a constant current fed sinusoidal oscillator with a low pass filter at its DC output provides a substantially DC voltage related to the resistance at its AC input. An analog to digital converter converts the substantially DC voltage to a corresponding binary digital signal that is input to a programmed microprocessor. A manually operable set point switch coupled to the microprocessor is acatuated by the user which actuation establishes a resistance level with the pad (return electrode) in place on the patient.

Abstract: An apparatus for cleaning air filters by a combination of vibration, air pressure, and suction. A support member includes a first inclined wall sloped more steeply than a second inclined wall, providing generally V-shaped supporting surfaces which cause the filter being cleaned to rotate as it is vibrated. The vibration of the filter also loosens trapped impurities therefrom, and this vibration is enhanced by resiliently suspending the support member from a housing. The loosened impurities fall down the slopes of the inclined walls and are removed by suction provided in a channel extending lengthwise along the bottom of the support member. An exhaust blower is connected to a port in the suction channel to apply suction to the filler and to remove loosened impurities. The exhaust blower is also connected to an inner suction tube, which applies suction to an inner periphery of the air filter.

The inside of the opposed wall portions are coated with a viscid, non-hardening material preferably a polyglycol which minimizes leakage of helium and a like gas through the valve when the body is inflated.

Abstract: The problem of having dirt and debris stick to the shank of a subsoil plow is solved by providing a non-stick cover body that attaches to a lower portion of the shank and is sized and configured and of a material to which dirt and debris will not adhere. Fasteners in the form of staples insert into holes in laterally spaced tail edge portions is provided. The body is made of a sheet of ultra high molecular weight-polyethylene that is sized, and then bent around a mandril, heated, then cooled and machined as required to be generally complementary with the shape of the lower portion of the shank to which the body is fastened.

Abstract: A method and apparatus for isolating electric power lines includes an insulator assembly to which is pivotally connected two line clamps. After the clamps clamp to the wire, the wire is cut so that the insulator isolates the line. In one form the clamping surfaces are curved in the longitudinal direction to make up for the loss of line length due to the elongation of the assembly under line tension. Cut-out assemblies for fuse and disconnect purposes are readily applied to the assembly by a lineman standing on the ground below.

Abstract: An apparatus for making a panel, preferably a panel having a base and two sidewalls extending from opposite sides of the base and having lateral flanges. The apparatus includes a frame having a series of sets of forming rollers for forming flat sheet metal into the panel. A partially formed panel rests on a pair of spaced base dies, with the sidewalls supported by two pairs of spaced support dies. A shearing blade is driven in a reciprocating motion between a raised position and a lowered position moving past the dies to shear the panel. Preferably, the cutting edge of the blade includes a series of concave serrations along its length, with each serration having an arc terminating in an apex at both ends. The pairs of support dies are removably mounted so that they may be replaced by other die pairs to provide support for different configurations of panel sidewalls and edge flanges. In addition, one of the pairs of support dies is laterally adjustable to accommodate panels of different widths.

Abstract: A bonding jumper is mounted on one facing surface of first and second coupling means which are threadably interconnected. The bonding jumper has a plurality of resilient detent members for bearing against the facing surface of the other coupling means to establish a redundant electrical bond between the first and second coupling means when the facing surfaces are axially drawn toward each other. A plurality of recesses is provided in the second surface for coacting with the detent means to yieldably resist opposing relative rotation in the unthreading direction.

Abstract: Disclosed is a dental hygienic pet toy for dental prophylaxis on the teeth of a dog or other carnivore as the toy is chewed by the carnivore. The toy includes an elastomeric body having an outer surface and at least one groove which opens onto the outer surface. The groove is sized and configured so that a functional prophylaxis lip will scrape plaque and other debris from a tooth and gingiva of a carnivore which is repeatedly inserted into and at least partially withdrawn from the groove as the toy is chewed by the carnivore. An oral hygiene substance may be provided along the lip to enhance the benefit to the teeth and gingiva.

Abstract: A portable support boom for window washers is provided on a support frame which has extendable boom sections that can be folded into a collapsed position and includes transporting wheels and handles so that the boom can be manually rolled from one place to another. When at the work site, the boom sections can be unfolded, then can be used either in extended or retracted position. A support frame attaches to the folded booms when in collapsed position and can be erected to form a triangular configuration for supporting extending end of the boom when in the work position. Support wheels are provided on the support frame for moving the boom laterally between different work positions at the same work site. A brake can be provided to releasably lock the support wheels at each work position. Also, the support frame can be selectively pivoted at each work position to bring the transporting wheels into contact with the supporting surface to inhibit lateral movement of the boom during use.

Abstract: An improved printing support and method for use in a conventional dry lettering printing machine of the type having a print station, a rotatable printing support having print characters thereon, and means for causing the machine to execute a print cycle which includes providing a color carrying ribbon and image carrying tape at the print station, aligning the ribbon, tape, and a selected print character at the print station for printing, exerting a printing force at the print station, and reciprocating the tape cartridge to advance the tape and ribbon to print the next character at the print station. The improvement comprises inverting the print characters relative to a readable orientation so that when the characters are printed on a first tape surface and the tape is inverted, the characters appear in the correct sequence and orientation when viewed through the tape from a second tape surface opposite the first. The tape will thus be readable when inverted and placed on the underside of a transparent sheet.

Abstract: The invention comprises a mobile concrete batch plant transportable by highway as a single unit. A cement storage hopper, a cement weigh hopper, and an aggregate weigh hopper are mounted on a standard trailer bed. The cement hopper is loaded to the desired weight from the storage bin, and the aggregate hopper is loaded as desired by a front end loader. A charging conveyor carries discharged cement and aggregate from the hoppers to a point above two oppositely facing mixing drums. The charge is dumped from the conveyor into a load hopper, and from there into a load diverter which directs it into a selected one of the two drums. Water and admixture are added and the mixing drum rotates, mixing the contents and producing concrete. The finished concrete is removed from the drum by reversing the rotation thereof, and is carried from the plant by a discharge conveyor. A second batch may be begun while the first is being mixed or discharged.
