Abstract: A drain cleaner includes a base unit having a housing, a drive arrangement positioned within the housing, and a motor coupled to the drive arrangement and supported by the housing. The motor is operable to selectively drive the drive arrangement. The drain cleaner also includes a drum unit removably coupled to the base unit. The drum unit has a drum that engages the drive arrangement when the drum unit is coupled to the base unit to rotate the drum, and a cable stored within the drum and selectively extendable out of the drum and into a drain.

Abstract: A tool support includes a frame that is configured to support a tool and a powered track supported on the frame. The powered track includes a drive roller, an idler roller, and an endless belt that extends around the drive roller and the idler roller. The tool support also includes a first motor supported on the frame. The first motor is operable to drive the drive roller and rotate the endless belt. The tool support further includes a second motor supported by the frame. The second motor is configured to be coupled to the tool to drive the tool supported on the frame.

Abstract: A sewer cleaning machine includes a frame and a drum rotatably supported by the frame. The drum is positioned on a first side of the frame. The sewer cleaning machine also includes a first motor supported by the frame and coupled to the drum. The first motor is operable to rotate the drum. The sewer cleaning machine further includes a cable positioned at least partially within the drum. The cable is configured to be extended from and retracted into the drum. The sewer cleaning machine also includes a track positioned on a second side of the frame. The track includes a first endless belt configured to rotate about a first roller. The sewer cleaning machine further includes a second motor supported by the frame and coupled to the first roller. The second motor is operable to drive the track.

Abstract: A method is provided for preventing or reducing the risk of restenosis following angioplasty by administering a retinoid, such as an RAR-selective retinoid, e.g.

Abstract: Retinoid-like compounds which act as agonists of the RXR retinoid receptor sites induce apoptosis of tumor cells in cell cultures, and are used as drugs to treat tumors in mammals including humans. Compounds which are specific agonists of RXR receptors and also compounds which are agonists of both RAR and RXR agonist (pan-agonists) induce apoptosis, although the RXR agonist compounds are preferred as drugs to avoid undesirable side effects associated with RAR agonist activity. The RXR agonists compounds are administered to mammals afflicted with tumors in pharmaceutical compositions adapted for systemic topical or for intralesional administration. The range of concentration of the active ingredient RXR agonist compound in the pharmaceutical compositions is approximately between 0.001 and 5 percent by weight, and such that the composition delivers approximately 0.1 mg to 100 mg of the active ingredient per kg body weight of the patient, per day of treatment.

Abstract: A method of extending the shelf life and of enhancing the keeping quality of fruits which comprises contacting said fruits with amines selected from the group consisting of naturally occurring monoamines, diamines, polyamines related amino acids and their non-toxic salts; esters of naturally occurring related amino acids; naturally occurring precursors of monoamines, diamines, polyamines and their non-toxic salts; naturally occurring metabolites of monoamines, diamines, polyamines and their non-toxic salts; and synthetic analogues of the naturally occurring monoamines, diamines, polyamines and their non-toxic salts.

Abstract: An electrolytic diaphragm cell for the production of halogen, hydrogen and an alkali metal hydroxide solution by electrolysis of an aqueous alkali metal halide solution, the cell comprising a plurality of anodes vertically mounted on the base of the cell, a cathode box providing cathodes between adjacent anodes, and a hydraulically permeable diaphragm between adjacent anodes and cathodes comprising one or more sheets of a porous non-melt-processable fluorine-containing polymer joined into the form of an endless-belt by a strip or strips of melt-processable fluorine-containing polymer fused into the sheet or sheets at or near juxtaposed edges of the sheet or sheets, the diaphragms being connected to upper and lower slotted supports of a melt-processable fluorine-containing polymer by means of strips of a melt-processable fluorine-containing polymer bonded to the supports at or near the slots therein and fused to the upper and lower edges of the diaphragm.

Abstract: An electrolytic diaphragm cell for the production of halogen, hydrogen and an alkali metal hydroxide solution by electrolysis of an aqueous alkali metal halide solution, the cell comprising a plurality of anodes vertically mounted at one side of the cell, a cathode box mounted at the opposite facing side of the cell providing cathodes between adjacent anodes, and a hydraulically permeable diaphragm between adjacent anodes and cathodes, comprising a sheet of a porous non-melt-processable fluorine-containing polymer connected to an upper and lower slotted supports of a melt-processable fluorine-containing polymer by means of strips of a melt-processable fluorine-containing polymer fused to the upper and lower edges of the diaphragm. The diaphragm preferably comprises a plurality of sheets of the non-melt-processable fluorine-containing polymer which are joined together by joining strips of melt-processable fluorine-containing polymer fused into the sheets at or near juxtaposed edges of the sheets.

Abstract: A device for supporting a sheet diaphragm on to a surface of a cathode which is made of a flexible insulating material and which can be caused or allowed to expand into the space between the anode and the diaphragm so that the diaphragm is pressed into contact with the cathode.
