Abstract: A physical therapeutic instrument for treatment of hemorrhoids is disclosed. The instrument treats existing hemorrhoids through a nonoperative method and prevents possible anal diseases. The instrument has a rectal insert having a shape agreeable to the anal anatomy of the human body. The rectal insert is carried on a carriage and is movably orthogonally received in a through hole of a seat of the instrument. The rectal insert is lifted and inserted into the rectum by a lifting unit and vibrated vertically and/or horizontally by a vibration unit. The rectal insert also heats the rectum at about 36.degree.-60.degree. C., thus providing a heating effect for the rectum. Insertion of the rectal insert into the rectum also pushes up drooping anal sphincter muscles, thus strengthening the anal muscles. The instrument thus maintains and strengthens active contractible motion of the anal muscles.

Abstract: The invention relates to a multilayered water-repellent film formed on a glass substrate by the sol-gel process. The film has a first metal oxide layer which is formed on the glass substrate by the sol-gel process and a second water-repellent layer formed on the first layer. As a first method for providing the film with superior durability of water repellency, mechanical strength and chemical resistance, the first layer is prepared by using a mixture of three specific sols which are respectively prepared from metal alkoxides or metal acetylacetonates. As a second method for providing the film with the above advantages, the second layer is prepared by using a coating mixture comprising a fluoroalkylsilane, tin oxide particles doped with antimony oxide, a silicon compound, water and an organic solvent.

Abstract: A mounting device for bearings placed on shaft extensions consists of a lower support basin rigidly connected with the frame and of a lid, connected in a pivoting manner with same, provided with a lower lever forming the operating portion which, when the lid is in the open position, extends into or across the support basin far enough to pivot the lid into its closed position by lowering the bearing abutting against it and placed on the shaft extension; in which closed position the basin rests tightly against the bearing with its circular, curved inner side. For the sake of simplification, a single lid is provided in a pivoting manner with a locking lever, which has at its end a hook portion, which engages an abutment of the support basin. Furthermore, an arrangement is provided which automatically pivots the locking lever.
