Patent EP-0283755-A1 (EP)
Inventor: DEYEN HEINZ
IPC: F04C2/12
Filed: 1988-02-25
Abstract: An apparatus for distributing inhomogeneous liquids, notably liquid manure, has a distributing member which comprises a distributing vessel for introduced liquid with a number of outlet apertures for connectable discharge lines. The distributing vessel is divided by partition walls into a plurality of separate conveying chambers each containing a pair of rotary pistons of the Roots-rotor type. All conveying chambers are openly connected to one another on their liquid supply side and on their liquid discharge side are each provided with a separate outlet. Each separate outlet from the conveying chambers is subdivided into two individual outlet ducts each of which is assigned to one of the two interacting rotary pistons of the pair of rotary pistons in the associated conveying chamber. With the pair of rotary pistons in circulatory operation, the two outlet ducts can be alternately isolated from or connected to the conveying chamber by their associated circulating rotary pistons.   <IMAGE>
Patent EP-0290780-A1 (EP)
Inventor: DUPRAZ JEAN-PIERRE
IPC: G01R19/00
Filed: 1988-04-06
Abstract: The device incorporates a Sagnac interferometer which includes phase modulation means (18, 19) in its optical loop, making it possible to modulate the phase difference between the two light waves propagating in opposite directions through it. Electronic means (32, 33) process the signal from the photodetector (14) receiving the beating of the two waves. The device is noteworthy in that it includes amplitude modulation means (70) acting on the power emitted from the light source (12) and in that the electronic processing means include a synchronous demodulator (32) operating at the low beat frequency between the amplitude and phase modulations and not at the very high frequency of the phase modulation itself. <IMAGE>

IPC: D21F1/20
Filed: 1988-06-22
Abstract: The motor-driven unbalanced oscillating mechanism (1) can produce horizontal oscillations in a mass (2) without heavy vibration being transmitted to the machine foundations and, for example, to the building, in this case. In order to compensate for the mass forces, at least one pair of weights (4) is caused to rotate in mutually opposite directions of rotation, in synchronism with the oscillation frequency. The device (8) producing the oscillations, the mass (2) and the weights (4) are connected by a force fit. When the mass (2) is at its point of reversal, all the weights (4) are in a position on the circumference in which the direction of their centrifugal forces opposes the direction of the mass forces of the mass (2). In the vertical position, the centrifugal forces of the weights cancel each other out. <IMAGE>

Abstract: In opening units for an open-end spinning machine it is possible, by means of fibre parallelisation segments inserted into the walls of the housing, to increase the quality of the spun yarn, since the fibres are attenuated and parallelised before entry into the spinning apparatus. If these parallelisation segments, however, are inserted as components into the walls, this results in edges and overhangs which lead to air eddies and where fibres can get trapped in the gaps.
