Granted: 2004-01-13
Abstract: An hydraulic actuator assembly for a power steering ram of a marine inboard/outboard drive of the type where the ram is connected to a tiller arm and has a spool valve mounted on the ram. The spool valve has a fastening tube which opens the spool valve when displaced in either direction to supply hydraulic fluid to the ram to move the tiller arm in the direction the fastening tube is displaced. The assembly includes an hydraulic actuator having a cylinder with an internal piston and a rod connected to the piston and sealingly extending from a first end of the cylinder. The rod has a distal end which connects to the tiller arm. The cylinder has a connector on a second end thereof. There is a mounting bracket extending generally radially from the cylinder which has a first end connected to the connector of the cylinder and a second end which is distal with respect to the cylinder. The second end has an aperture for connecting the bracket to the fastening tube of the spool valve.  The actuator may have a stroke limiter for preventing excessive travel of the ram including a passageway through the piston and a normally closed valve on the passageway. A rod extends slidably through the passageway and beyond the piston to open the valve before the piston reaches the end of the cylinder.

Abstract: A novel method is described for joining aluminum to metal surfaces by brazing. The method comprises (a) applying as a coating to at least one of the metal surfaces to be joined a mixture of a metal (e.g. Si, Cu or Ge) and a brazing flux, the metal of the mixture being adapted to form a brazable eutectic with one or both of the surface metals, (b) heating the surfaces and the coating in juxtaposed relation to a temperature above the brazing alloy melting point to thereby dissolve oxide film on the surfaces to be joined, cause the metal of the coating to dissolve into the oxide-free aluminum surface and form therewith a brazing alloy layer and form a brazed assembly and (c) cooling the brazed assembly to form a solidified joint between the surfaces. This has the advantage of providing for the joining of metal surfaces, such as aluminum, to aluminium, copper, brass or steel surfaces, by brazing without the prior formation of a brazing alloy cladding on the surfaces to be brazed.

Abstract: A multichannel television access control system is disclosed wherein processing of the broadbande signal is performed by gated coherent RF injection on a plurality of channels, thereby effecting selective descrambling of an arbitrary subset of channels in a channel group. The system provides for a closed loop injection signal phasor control so as to maintain substantially constant relationship between the television signals and the injected signals. The combined signals are supplied to subscribers enabling the use of their cable ready equipment. The broadband signal is coupled to a broadband amplifier (104) via a power splitter (102). The injected signals are combined through line (114) with the amplified broadband signal by directional coupler (108), resulting in the composite signal on line (109). The broadband signal on line (109) is fed to the subscriber part (112) through directional tap (110). The injected signals forming together the composite signal injected at line (114) are generated by a digital broadband generator (136) feeding RF switch (116). During the time in which injection is required, RF switch (116) is at position (117) as shown in the figure.

Abstract: A security document is produced from a paper substrate having invisible hydrophobic toner blended into the paper. The clear toner is produced by milling (11) and classifying (12) a polyester resin, mixing it with a silica flowing agent (13), and then electrostatically imaging the toner (16) onto the paper substrate. An infrared absorbing a UV responsive dye may be added to the toner so that it is visible under infrared/ultraviolet light respectively. When applied to the paper the toner is snow white, but after infrared heat fusing (18) it blends into the paper and is substantially invisible. The security indicia is easily made visible by passing a conventional marker nib over it, or other mechanism for applying a water based low concentrate colored ink (20) which is readily absorbed by the surrounding paper, but not by the hydrophobic security indicia.
