Abstract: A filter assembly incorporates a system for jacking a fitter canister (13) into and out of engagement with a filter head (11). A threaded jackscrew (15) is mated to a threaded portion of the filter head and rotatably mounted on the filter canister, but longitudinally confined near the canister top. The assembly can accommodate a second class lever (46) the fulcrum of which lies in a notch or other recess (44) in the filter head. The jackscrew includes a plurality of circumferentially-spaced lugs against which a portion of the lever can act. The manual application of force to the free end (46B) of the lever creates a mechanical advantage of the jackscrew lugs (48) such that a torque sufficient to free and turn the jackscrew can be generated. Repeated pivoting of the lever against successive lugs of the jackscrew in a ratchet-like manner unscrews the jackscrew, and the captive canister, from the filter head.

Abstract: A method in the production of hydrogen peroxide is described, utilising the so-called anthraquinone process in which alkylated anthraquinones dissolved in organic solvents to form a liquid working solution, are alternately reduced and oxidised. The working solution is subjected to catalytic hydrogenation by contacting it with hydrogen in the presence of a hydrogenation catalyst. The contact with hydrogen is established in a fixed catalyst bed comprising one or more solid catalyst bodies, each of which consists of a thin-walled, coherent. solid body of a structure forming parallel channels through which the working solution and hydrogen gas are allowed to pass. The channels of the catalyst bed are of equal length and parallel to the direction of flow of the working solution.

Abstract: A two-wire power and position control system uses a pair of electrical conductors between a central station and remote station. The remote station is arranged to generate a physical displacement by a permanent magnet DC motor and attached gear-linkage mechanism. Pulsating voltage is applied to the two-wire connecting link from the central station to the remote station as the power source for the DC motor. The physical displacement information of the remote station is extracted by the central station within the off-cycles of the pulsating power signal. In the first arrangement. the remote station enables or disables the flow of back-EMF signal generated by the permanent magnet DC motor as a means of position indication. In the second arrangement, the remote station is arranged to sequentially connect various impedance to form part of a voltage divider network in combination with circuit elements at the central station. The change in impedance is used to affect a voltage derived from the voltage divider at the central station. In either arrangement, the central control station will be capable of monitoring and controlling the position of the remote station.
