IPC: B21J13/10
Filed: 1989-12-23
Granted: 1991-06-20
Abstract: A workpiece manipulator assembly for a forging press having a press ram comprises a workpiece rotating mechanism including a rotary drive system for rotating a workpiece in peripheral direction. The rotary drive system is operated by a drive motor running at a preselected constant speed to rotate the workpiece about an axis of rotation. An arresting assembly stops the rotary movement of the workpiece before and during a pressure contact phase for the press ram. The rotary drive system is adapted to rotate a driven worm which produces rotary movement to the workpiece rotating means and is mounted for axial displacement. The arresting assembly includes an axial drive unit for predeterminably controlling axial displacement of the driven worm to effect the arresting of said rotary movement.

Abstract: PCT No. PCT/EP88/00598 Sec. 371 Date Jan. 5, 1990 Sec. 102(e) Date Jan. 5, 1990 PCT Filed Jul. 5, 1988 PCT Pub. No. WO89/00086 PCT Pub. Date Jan. 12, 1989.In a manually operable discharging apparatus, the discharge nozzle has an at least two-stage atomizer, in which the medium flow, following pre-atomization, is atomized by surge-like acceleration with a whirled, fine compressed air flow, e.g. according to the Laval, effect, so that even finer droplets are obtained. For this purpose to the discharge nozzle, a separate compressed air channel portion upstream of the end opening supplies compressed air from a time immediately before the supply of medium to a time after its supply. The compressed air can be produced in simple manner by a compressed air pump combined constructionally with the medium pump and operable together therewith by means of a single handle and which in the extension of medium pump is provided immediately adjacent to its outer end and whose pump cylinder is formed by the cap-like handle. The compressed air flow can also be passed to other points of the discharging apparatus, e.g. for cleaning the medium outlet channel for discharge nozzle and can be used for control functions for valves, particularly outlet valves.

Granted: 1996-05-27
Abstract: FIELD: aeronautical engineering; flying vehicles. SUBSTANCE: method consists in selection of optimal area and scanning it in accordance with pitch control stick position, as well as angle of incidence of top wing relative to lower wing and to incoming flow at change of angle of attack of flying vehicle. Top wing 6 moving relative to lower wing 5 at change of balanced position of control stick 1 is constantly set at favourable angle of attack relative to vector of incoming flow local velocity. Besides that, top wing 6 forms converging passage with upper surface of lower wing at each position. Flow in converging passage is accelerated and magnetude of velocity gradient increases and flow break-away from lower wing is dragged to large angle of attack. Application of this method provides for increase of maximum magnitude of lifting force coefficient (C max ) and critical angle of attack (α cr ), as well as for extending the range of flight angles of attack due to maintenance of high aerodynamic property.
