Abstract: The ink jet head assembly disclosed herein has modular subassemblies with predetermined relationships between the subassemblies to minimize realignment of the ink stream when a subassembly is replaced in the field. The head assembly is modularized into nozzle (30), charge electrode (90), deflection electrode (106), sensor (18), and gutter (122) subassemblies. The charge electrode module (90) is mounted on the nozzle module (30) in a manner such that no field adjustment is necessary to centre the charge electrode 104 horizontally to the ink stream. The deflection electrode module 106 is mounted on the sensor module (18) in a manner such that no field adjustment is necessary to centre the deflection electrode (112) horizontally to the ink stream. The nozzle and charge electrode subassembly (30, 90) have a preset adjustment and the senor, gutter and deflection electrode assembly (18, 106, 122) have a preset adjustment such that no field adjustment between these subassemblies is necessary to maintain a constant flight distance for the ink drops. Finally, the nozzle module 30 is adjustable to reposition the ink stream about the pitch axis (vertical adjustment) and the yaw axis (horizontal adjustment). The yaw axis adjustment may be preset. The pitch axis adjustment is the only mechanical adjustment necessary in the field when replacing the nozzle module.

Abstract: A variable-pitch marine propeller comprises helicoidal blades 6 each mounted on a hub 1 to freely pivot about radial axis 25 spaced in front, in the direction of rotation, of the center of pressure of the blade 6 whereby water pressure acting on the blade exerts a torque which tends to turn it about its axis in a direction to bring the surfaces of the blade into line with the flow of water over it. The axis 25 is also spaced behind, with respect to the direction of movement of the propeller through the water, a major portion of the pressure surface of the blade whereby, the resultant of the drag of the water exerts a torque which tends to turn the blade in an opposite direction. The shape and mass distribution of the blades relative to their pivot axes are also such that centrifugal effects tend to move the blades, in the absence of hydrodynamic forces, into a pitch equal to that of the helicoid. In operation each blade adopts a stable equilibrium position in which its pitch is optimally suited to the speed of rotation and the linear axial speed of the propeller.

Abstract: A novel system for producing film by extruding and/or casting at leasttwo layers of resin, (2,3) such as polyacrylonitrile homopolymer or interpolymers. The system provides for co-extruding a continuous multi-layer film with continguous or tandem dies (31,32) from a first supply of homogeneous resin solution (10) and a second supply of non-homogeneous redissolved resin scrap (84). The film (1) may be cast onto a smooth cooled drum surface (30) to form substantially continuous adjacent layers from two or more resin supplies. By stripping the film from the drum as a continuous film strip and stretching (50) the film an oriented structure is provided. Scrap resin, such as selvage trimmed from the stretched film or mill scrap, is comminuted (82) and redissolved in solvent (84) for recycle to the second supply (32) of the extrusion step. The homogeneous layer prevents film disruption by inhomogeneities present in the contiguous layer containing redissolved scrap, which might cause localized stresses in the film and discontinuities during stretching.

Abstract: The combination of certain polyvalent metal ions with certain proteinaceous foaming agents significantly enhances the efficacy of proteinaceous foaming compositions. The present invention affords the means for achieving significantly improved protein foam from vegetable protein hydro- iyzates which normally fail to possess the foaming efficacy of conventional proteinaceous foam agents such as egg albumen and caseinates. The improved foamed products may be obtained by employing a combination of polyvalent ions such as calcium and zinc with enzymatically hydrolyzed soy protein whipping agents which are soluble throughout the pH range 4 to 7. The proteinaceous foaming compositions may be utilized for a variety of industrial and food applications and are particularly useful in providing coated paper products.

Abstract: One of the transmission facilities (101) of a TASI system is used as an order wire, via which channel signalling information and assignment information are transmitted. Signalling information is transmitted periodically in frames on the order wire for only some of the channels (100), connected to the system, at any one time. Accordingly, the assignment information consists of both channel-to-facility assignment information, relating to the assignment of channels to the other facilities, and channel signalling assignment information, relating to the assignment of channels to signalling bit time channels in the frames on the order wire. One assignment can be transmitted in each frame, and frames not used for transmitting assignment information can be used for transmitting commands and messages. The system avoids the need to transmit multi-tone signals preceding speech bursts on the transmission facilities and avoids lengthy delays in the transmission of channel signalling information.
