Title: Pyrazolotriazoles and processes for their formation
Inventor: ARNOLD ROBERT W
IPC: C09B26/02
Filed: 1990-02-20
Abstract: This invention relates to novel pyrazolo-[5, 1-C] (1, 2, 4) and (1, 3, 4)-triazoles having an acyloxy group in the 7-position and to a method for their formation. The method utilizes the corresponding 7-acyl compounds as starting materials. These compounds can be made from the corresponding 1,7-diacyl compounds. The 1,7-diacyl compounds utilized can be prepared by a new method for diacylation of pyrazolotriazoles, where the acetylation is acid catalyzed. The compounds produced are used as dye couplers.
Patent CA-2027555-A1 (CA)
IPC: A47K10/28
Filed: 1990-02-12
Abstract: The cloth towel dispenser appropriately comprises two towel units, whereof each unit is independently completely operational.  The cloth towel is guided over a delivery roller into a draw-in roller   .  On pulling out the towel for forming a towel loop, the delivery roller     is also rotated, as is the draw-in roller      via an envelope drive    .  In the draw-in shaft     is located a spring tension accumulator    , which is tensioned on pulling out.  By means of a cam wheel      and a catch     , the length of the towel which can be pulled out is limited.  As also a part of the used towel wound from the draw-in roller      can be retracted, the length of the clean towel to be pulled out can be kept smaller. After a certain interval a timer releases the catch     , so that the spring tension accumulator rotates the draw-in roller      and the cloth loop     is wound up.

Title: Shield for trees
Inventor: HENRI JACQUES
IPC: A01G13/10
Filed: 1991-02-15
Abstract: SHIELD FOR TREES ABSTRACT OF THE DISCLOSURE The shield serves to surround tree trunks especially along city streets in order to protect the same against damage by snow plows and other moving vehicles. For small trees, one shield, mainly containing rubber reclaimed from used tires, is wrapped spacedly around the tree trunk and held in curved condition by means of rigid straps. For tree trunks of greater diameter, at least two sheets of the same material are joined together and made to surround the tree trunk being held around the same by suitable strapping. In this latter case, the lower portion of the sheet forms a skirt composed of a plurality of tongues which can be spread out to make room for any protruding tree roots. In both embodiments, each sheet has elongated openings to increase the transverse flexibility of the sheet, to permit easy curving of the same around the tree.

Inventor: ABE TOSHIAKI
IPC: H01C1/028
Filed: 1991-05-28
Abstract: A self-resetting overcurrent protection element uses an element body made up of a mixture of polymers and carbon black grafted with polymers. A resilient sheathing material covering the element body permits free expansion of the element body to permit the resistance of the overcurrent protection element to increase substantially in response to Joule's heating from high current. The sheathing materials preferably are made of elastic epoxy resins or silicone resins that allow significant expansion of the element body at the time of overcurrent protection, thus increasing the ratio of resistance in the element between an overcurrent state and a normal operating state.

Abstract: The invention relates to a process for the treatment of wash water from the gas washing system of an iron ore reduction plant, the wash water being brought into direct contact with the dust-laden gas in a gas washer, is removed from the latter and after solids separation is again supplied in cooled form to the gas washer. According to the invention this problem is solved in that wash water which is substantially freed from solids in a concentrator or thickener (1) is passed via a hot water tank (2) into a cooling tower (4) where the water is cooled and where there is simultaneously a separation of dissolved carbon dioxide, an enrichment with oxygen, a conversion of the calcium and magnesium hydrogen carbonates into carbonates and iron bicarbonate, as well as iron sul-phate into iron(III)-hydroxide and that said chemi-cally destabilized wash water is freed from the re--formed and residual solids in a further series-con-nected thickener (6) by adding flocculating and coa-gulating agents, is chemically stabilized and passed over a cold water tank (7).

Title: Auxiliary means for fastening a capping on bone tissue or the like
Inventor: BUSER DANIEL
IPC: A61B17/86
Filed: 1992-03-10
Abstract: It is known per se that covering of the depth of a bone with a polytetraethylene film can lead to formation of the bone substance in the depth which fills this depth. Hitherto, however, this technique for restoration of a jaw bone was restricted to shallow depths. For example, it was impossible with this method to induce new growth of bone between two teeth or between a tooth and a dental prosthesis inserted in the bone. The new means with which this can be achieved is formed by a pin (1) having a bead (2) for fixing of a film (42) on one end, an external screw thread (3) intended for screwing into the jaw bone (41) on the other end and a smooth-walled section (5) inbetween, the diameter of which is preferably larger than the diameter of the external screw thread.
