Abstract: An air nozzle is provided which produces high thrust with low noise. The nozzle is adapted to provide flow amplification by inducing flow of ambient air with high pressure air.

Abstract: System for storing computer printouts or the like which includes a cabinet or shell supporting a plurality of trays which may be removed from the cabinet or be partially pulled out of the cabinet to view a printout supported by the tray. Provision is provided in the preferred embodiment for binding the computer printout to the tray supporting the printout.

Abstract: A novel one-piece holder is provided for binding a multi-leaf computer printout and mounting the same in a suspension-filing and/or storing system.

Abstract: The invention consists of provision of novel noise-silencing fluid-discharge devices which provide superior noise reduction. The devices comprise one or more flow-modifying elements which are made by rolling and compacting knitted metal wire mesh fabric. A preferred embodiment of the invention is an air discharge nozzle which is characterized by a high air discharge velocity while simultaneously effecting a sharp reduction in noise.

Abstract: A fluid exhaust silencer is disclosed which comprises a hollow, cylindrical, fluid-permeable noise-reducing element made of a wire mesh material. The noise-reducing element is mounted in a housing which is adapted to be connected to an exhaust for a pressurized fluid. The housing is made so that the pressurized exhaust fluid flows into one end of the housing and is discharged from the side of the housing after passage radially through the noise-reducing element.

Abstract: A system is described for stabilizing a resiliently supported body in order to permit translational motion while preventing angular motion within at least one predetermined plane. The system comprises the body to be supported, at least one sheathed cable, and fixed mounting supports. The end portions of each cable and sheath are connected to the body and to the fixed mounting supports in such a manner that motion of that part of the body connected to one end of a sheath or cable results in a force exerted by the other end of the sheath or cable to move that part of the body connected to the said other end of the sheath or cable so that motion of the body is substantially purely translatory.

Abstract: Guard device for storing a disk package comprising a jacket containing a flexible magnetic disk, said device being substantially rigid and having a front or cover surface, a back surface, sides and a bottom, said cover surface being preferably shorter in length than the back surface to permit a label on the jacket to be observed as well as to permit writing on the label and the sides preferably extending above the cover to protect the side edges of the disk package. The device also preferably includes ribs to protect a pocket for the disk package as well as restraining ribs located at the bottom of the pocket.

Abstract: Damping of turbine or compressor vanes loosely supported in an outer shroud is accomplished by means of resilient metal damping pads which have slots to accommodate the outer ends of the vanes. The damping pads engage the opposite sides of the vanes and the slots are formed so as to provide gaps or relief areas between the pads and the side and end edges of the outer ends of the vanes.
