Abstract: Process for the preparation of ferrierite which comprises maintaining an aqueous starting mixture containing at least one silicon compound, at least one aluminium compound, at least one alkali metal (M) compound and at least one organic nitrogen com­pound (RN) selected from the group consisting of piperidine, pyridine, allyl-substituted piperidines and -pyridines, piperazine, 4-picoline and 4-picoline-N-oxide, at an elevated temperature until crystalline ferrierite has formed, in which starting mixture the various compounds are present in the following molar ratios, the aluminium-, silicon- and alkali metal-compounds being calculated on basis of the oxides: 
    SiO₂ : M₂O = 7.3 to 15.6, 
    SiO₂ : Al₂O₃ = 15.6 to 35.7, 
    H₂O : SiO₂ = 5 to 500, and 
    RN : SiO₂ = 0.05 to 1.0. 
     The ferrierite catalyst precursor thus prepared can after conversion into the hydrogen form be used as catalyst (carrier) for dewaxing hydrocarbon oils (e.g. lubricating base oils).

Abstract: A variable dual phase shifter for simultaneously varying the phase shifts in two signal paths by equal and opposite amounts comprises two 90° hybrids (5, 6) in the respective signal paths (1, 2; 3,4), and a pair of substantially identical transmission lines (7, 8) connecting output ports of one hybrid to output ports of the other. A number of variable-impedance radio-frequency devices (Z<sub>n</sub>, ... Z<sub>1</sub>, Z<sub>o</sub>, Z<sub>1</sub>, ... Z<sub>n</sub>) which are preferably p-i-n diodes, are connected to the transmission lines at positions (x<sub>"</sub>, ... x<sub>1</sub>, x<sub>0</sub>, x<sub>-1</sub>, ... x,) spaced apart along the length of the lines, the positions on one line corresponding to those on the other line. The impedances of the devices are controlled to create a reflective termination at a selected position on one line and a reflective termination at the corresponding position on the other line, so that the phase shift applied to each signal is determined by the distance of the reflective termination from the respective hybrid. The devices may be arranged in pairs as shown, each device of a pair being coupled to a respective one of the transmission lines. Alternatively, single devices may be provided, each device being coupled to a respective pair or corresponding positions on the lines via two ¼-wavelength lines. Two or more of the phase shifters may be connected in cascade to provide progressively finer phase shift steps.

Abstract: An apparatus which develops an electrostatic latent image recorded on a photoconductive member (10) employed in an electrophotographic printing machine having a finite, usable life. The apparatus employs a developer material (60) comprising carrier granules and toner particles. The developer ages during the life of the electrophotographic printing machine. A continuous supply of carrier granules is furnished from discharging unit 66 to the developer material as toner is replenished. The addition of these carrier granules extends the useful life of the developer material so as to correspond to at least the useful life of the electrophotographic printing machine.

Abstract: Une séparation de cassure satisfaisante de composants en métal léger est difficile à obtenir à cause de la ductilité inhérente du matériau qui se traduit par la déformation du métal lors de la séparation. Lorsqu'une telle déformation se produit, les deux moitiés de la cassure ne correspondent pas correctement l'une avec l'autre. L'invention prévoit le durcissement local d'un composant en métal léger dans la région de cassure, et les éventuelles techniques proposées consistent à former le composant autour d'un insert en matériau cassant (24), à modifier localement la structure interne du métal et à couler une armature en fil de fer cassant (26) dans le métal. Toutes ces opérations techniques peuvent également s'accompagner de la formation d'une encoche d'amplification de la contrainte (28) au niveau de la surface du composant.
