Title: Electrostatic ink jet printer electrode - has Y-electrodes as separate sloping elements or single zigzag element
Inventor: HORIKE MASANORI
IPC: B41J2/085
Filed: 1979-10-11
Abstract: The electrostatic ink jet printer has a jet followed by a charging electrode arranged to guide the ink droplets between electrodes (3) for control in the X direction and further electrodes (4) for the Y direction. The travel in the horizontal direction is controlled by the charge on the droplets, but travel in the vertical direction is independent of their charge. To achieve this effect, the Y electrodes (4') can slope at an acute angle to the line connecting them, each being individually connected to an earth point. In an alternative design, a single Y electrode is used, with zig-zag sections. In both cases, the main electrodes (4) at a higher potential, is parallel to the Y electrodes.

Title: Double-seat valve with leakage control and two valve plates which can be moved independently of one another
Inventor: BRAEKELMANN WOLFGANG
IPC: F16K1/44
Filed: 1981-03-10
Abstract: In double-seat valves with two valve plates which can be moved independently of one another, one of which can come to rest against the other after a predeterminable distance of travel when opening, special measures as regards the sealing of the valve seat surfaces and of the valve plates with respect to one another are required. For this purpose, the general practice is to provide at least three seals, the incorporation of which, with appropriate dimensioning of the valve plates, gives rise to annular gaps between the valve seat housing and the actual valve plates and these prevent the liquid which accumulates in this area from draining away. To avoid such annular gaps with the unavoidable accumulation of liquid, the invention proposes a double-seat valve in which the front face of one valve plate ends at the level of the front face of the associated valve seat, each of the valve plates (1, 2) having a seal (5, 6) and the seal (6) of valve plate (2), which is preferably larger, on the one hand extends into the area of the actual valve seat and on the other hand into the front-face area (8) assigned to the second valve plate (1), and this second valve plate (1) has, on its lateral surface facing this front-face area, a sealing surface, and provided between both sealing locations is a downwardly open recess which, in the closed position of the valve, forms a single space with the cavity formed by the two valve plates (1, 2). <IMAGE>

Title: Process and apparatus for the gravimetric filling of containers and bags in a coarse and a fine flow
IPC: G01G13/04
Filed: 1981-07-09
Abstract: The invention relates to a process and an apparatus for the gravimetric filling of containers and bags in a coarse and a fine flow. The object on which it is based is to abandon the known readjustment of the faulty weight, especially during the filling of inhomogeneous material, and to achieve, for the first to the last container or bag of a series of fillings, an identical or largely identical filling weight which comes very close to the desired weight or which coincides exactly with this. In particular, at the same time, the fine-flow time is to be kept as short as possible. For this purpose, provision is made for digitally recording the weight measurement results of short measuring cycles of equal length continuously during the filling operation of one filling and for determining from them the change-over point from coarse flow to fine flow and the cut-off point of the fine flow of this filling. The apparatus according to the invention provides a weighing device, recording the respective actual weight as a digital value at short constant time intervals, and a computer receiving these actual weight values and evaluating their respective difference.
