Abstract: A method and a device for detecting a gaseous anhydride and measuring its concentration in an oxygen-bearing gas. The method comprises the following steps: (a) forming an electrolytic junction by contact between a first solid-electrolyte element containing oxyanions of the anhydride to be detected and a second, 0.sup.

Abstract: A reagent for the early detection of cancer. The reagent is employed in a method comprising the steps of contacting the reagent which consists of bacillus agrobacterium tumefaciens adsorbed on red blood cells, yeast cells or particles selected from the group consisting of polyvinyl latex, kaolin and animal black, with a patient's blood serum and determining whether there a positive reaction of agglutination. The presence of such a reaction indicates that the patient has a cancer in evolution.

Abstract: A motorcycle luggage rack having a platform for carrying luggage and a support beneath the platform for supporting the same. The support is adapted to be fixed to the motorcycle. A pair of spaced apart links pivotably connects each side of the platform to the support so that the platform can be moved between rear and forward positions. A lock member or stop, locks the platform in either position.

Abstract: An individual safekeeping box comprising a protective enclosure with an access opening, a protective door with a lock therein, and cooperating mounting means of the door and the enclosure to removably mount the door on the enclosure to close the opening. The enclosure is preferably made in two parts, a top cover and a bottom plate. Means are provided for detachably connecting the top cover and bottom plate together and for locking the connected parts together.

Abstract: Method for the construction of a temporary shelter, comprising an even number of base modules of equal size each having an entrance at one end, the base modules being placed side by side in two rows with the base modules of one row facing in pairs those of the other row so as to form a hallway, the entrances opening into the hallway. Floor modules having the same width as the hallway are located between the pairs of facing base modules so as to join them at the bottom thereof. Two vestibule-forming modules having the same width as the floor modules are provided at the ends of the hallway so as to close it. The base modules are joined together by means of a first set of thin sheets of flexible sealing material each being removably secured between the front, the top and the rear walls of the base modules.

Abstract: Improvements in area space divider assemblies and components therefore. One component is the bridge means used in connecting two or more wall panels together to provide the divider assembly. The bridge means have projecting longitudinal edges equal in number to the number of panels to be joined together. Receiving means are provided at each end of each projecting edge. The receiving means extend longitudinally inwardly of the bridge means from each end and receive vertically extending connecting means on the panels. The bridge means can comprise a single bridge member for joining two, three or four wall panels together; or a bridge assembly consisting of two, three or four bridge members, joined by links, for connecting two, three or four panels. The invention also relates to novel wall panels and space divider assemblies.

Abstract: The invention relates to a digital converter and to a method for digitally converting a coded signal being at a delta rate into another coded signal flowing at a PCM rate. First, the code of the delta signal is converted into an intermediate code, this intermediate code being at a rate corresponding to the delta rate. Then, the rate of the intermediate coded signal is converted into the rate of the PCM signal. And, finally, the code of the intermediate signal is changed into the code of the PCM signal.
