Abstract: The invention is a fire hose holding apparatus that involves a hose clamp that involves two halves that are connected together via a hinge and a handle. Located along the interior of said two halves are rubber strips. The locking apparatus involves a locking clip on the opposite ends of the two halves and locking notch in the handle.

Abstract: The invention concerns a process for preparing titanates and zirconates respectively of formulas MTiO.sub.3 and MZrO.sub.3 where M is Ba.sup.2+, Sr.sup.2+, Ca.sup.2+, Pb.sup.2+ and Mg.sup.2+ to the exclusion of MgZro.sub.3, consisting of reacting an ester of formula M[H-(CH.sub.2).sub.n CO.sub.2 ].sub.2 where n=1-4 with the formula M'[O(CH.sub.2).sub.n CH.sub.2).sub.n CH.sub.3 ].sub.4 where M' is Ti or Zr bringing the reaction mixture to boil until the solvent is removed to yield a viscous translucent resin. The resin is cooled and further treated to obtain the desired product.

Abstract: The invention comprises a process for co-sintering of conductors of copper or copper-based alloy and a ceramic substrate, the substrate being produced from a ceramic powder of cordierite type, having a sintering temperature of lower than 950.degree. C.The process comprises the following steps:(a) shaping of the ceramic substrate from a powder of cordierite type,(b) deposit of copper on the ceramic substrate, and(c) co-sintering heat treatment, during which the organic compounds are removed, the copper is regenerated in a reducing atmosphere, and co-sintering of the conductors and the substrate is carried out in a flow of moist inert gas with a plateau at a temperature of between 1065.degree. and 1080.degree. C.The process according to the invention makes it possible to produce substrates of cordierite with internal and external conductors.

Abstract: The present invention relates to a cordierite (2MgO.2Al.sub.2 O.sub.3.5SiO.sub.2) type ceramic powder sintering at low-temperature defined in that its composition is: 60 to 50% SiO.sub.2, 5 to 20% MgO and 20 to 40% Al.sub.2 O.sub.3, and in that its specific surface area is not less than 50 m.sup.2 /g, this powder having a fritting temperature of less than 1,100.degree. C.The invention also relates to a process for the preparation of this powder, which consists in preparing a mixed alcoholic solution of an aluminum and silicon salt, in preparing a solution of an alcohol-soluble magnesium salt, in mixing the two solutions, in padding a hydrolyzing agent in the form of a totally volatile weak base to the solution, which leads to the formation of a gel, in subjecting the said gel to a first thermal treatment at a temperature not exceeding 450.degree. C., and in subjecting the said powder to a second thermal treatment at a temperature of between 450.degree. C. and 900.degree. C.

Abstract: Fireplace tongs comprising a pair of levers connected to one another between their respective ends by means of a first pivot in the manner of scissors, this first pivot defining on one side thereof operating arms and on the other side thereof extensions of the operating arms. One of the extensions constitutes a first jaw for the tongs while a second jaw, similar to the first jaw, is pivotally mounted at one of its ends to the end of the other extension away from the first pivot. A connecting link is provided of which the ends are pivotally mounted on the jaws respectively on one side and on the other side of the first and of the second pivot and adjacent thereto, whereby closing in of the arms causes tightening of the jaws and, alternatively, spreading apart of the operating arms causes loosening of the jaws.

Abstract: A boat is provided with an elongated vane extending along each side of the hull. This vane is supported in a closely spaced relationship with the hull's surface to define a longitudinally extending slot. The vanes so positioned reduce the tendency of the boat hull to drift out on turns, by biting into the water. These vanes may be provided with mechanisms to close off the slot when not needed.
