Abstract: 1,133,462. Developing electrostatic images. RANK XEROX Ltd. Dec.14, 1965 [Dec.28, 1964], No.53121/65. Heading G2H. A method of developing latent electrostatic images comprises cascading a mixture of granular carrier and toner particles across the image bearing member and contacting the member with a fluid suspension of toner particles to provide for edge and solid area development. The fluid suspension may be formed in gas or liquid, e.g. air, carbon dioxide, nitrogen, oxygen, trichlorotrifluorethane or Sobio Odourless solvent. Cascade development is carried out in known manner by a bucket conveyer 34, Fig.4. As developer 31 cascades over drum 21 toner particles are separated from carrier particles and deposited to form a visible image. Unused developer is guided down shoot 32 where it is formed into a cloud by applying a potential to shoot 32. Toner particles pass through a screen 33 adjacent the drum. The direction of drum 21 may be reversed to carry out the powder cloud development before the cascade development In a modification, Fig. 5 (not shown) the developer is cascaded into the space between a screen (33') and shoot (32').

Title: Liquid dampers
IPC: F16F9/48
Filed: 1973-11-21
Abstract: 1491208 Throttling systems in hydraulic dampers OLEO INTERNATIONAL HOLDINGS Ltd 21 Nov 1974 [21 Nov 1973] 53938/73 Heading F2S In a one-way circulation hydraulic pistoncylinder damper exhibiting flow from a reservoir 15 to the working chamber 19 via a one-way valve 17, flow from the chamber 19 to the annular working chamber (21) above the piston 12 via a one-way valve 18 in the piston, and flow from the annular chamber (21) to the reservoir 15 via a passage 23 and a damping valve 24-an alternative flow path from the annular chamber 21 to the reservoir 15 is provided, in at least some positions of the piston in the cylinder, by a passage 25 in the piston rod 13 bridging the piston rod seal 14 to connect the chamber (21) with the reservoir 15. Thus the damping varies in dependence on the mean position of the piston 12 in the cylinder 11, and hence on the static load of an associated vehicle. The piston rod passage may be a groove 25 which (as shown) decreases in cross-sectional area in the direction away from the piston. In the no-load position shown in Fig. 1A the groove 25 provides an unrestricted flow path to the reservoir, so that the effect of the damping valve 24 is minimized. At half load, as in Fig. 4, the groove 25 offers a more restricted flow to the reservoir. At full load (Figs. 2 and 3, not shown) the groove does not communicate with the reservoir, and all flow to the reservoir is via the damping valve 24. The groove may instead decrease in crosssectional area in the reverse direction, or may be in the form of a groove at each end only of the piston rod, or a groove in the central portion only. The groove may be stepped, in depth and/or width (Fig. 12, not shown) instead of varying progressively as shown. It may have a V-shaped or rectangular cross-section (Figs. 9 and 10, not shown). To reduce frothing the groove may be helical (Fig. 8, not shown). There may be a plurality of grooves in the form of a multi-start helix. The flow may be deflected by the base of a cup-shaped member 26 surrounding the piston rod, and pass to the reservoir 15 between its wall and the wall of tube 22. The air space of the reservoir 15 is bounded by a membrane 34, and a bellows (48, Fig. 1B, not shown) which surrounds the piston rod and is connected at one end to the piston rod and at the other end to the top of the membrane 34. With the piston rod extended as shown, the bellows is extended and the membrane is caved in. With the unit contracted (Fig. 2) the bellows is collapsed, but the membrane bulges out to accommodate the air.
