Patent EP-0851984-A1 (EP)
Inventor: CRONE ERIK
IPC: F02F5/00
Filed: 1996-09-18
Abstract: A piston ring (7) for a piston in an internal combustion engine is inserted in one of several axially separated annular grooves (3) in the peripheral surface of the piston. Each annular groove has an upper and a lower groove face (4, 5) as well as a groove bottom (6). The piston rings seal the working chamber (8) above the upper piston ring downwards during the compression and combustion strokes of the piston. The piston ring (7) has an axial height which is smaller than the axial distance between the upper and the lower groove face in the pertaining annular groove as well as a substantially gastight ring partition (9) allowing for an extension of the diameter of the ring at the mounting in the annular groove. Several leakage tracks (14) in the lower surface (15) of the piston ring are distributed over the periphery of the ring, said tracks being slit-shaped and having a slit width facing in the peripheral direction of the ring and being at least several times larger than the slit height (h) extending in the axial direction. When the bottom surface (15) of the piston ring abuts the lower groove face (5) leak gas may flow through the leakage tracks, which reduces the differential pressure across the piston ring.

Abstract: PCT No. PCT/EP96/03868 Sec. 371 Date May 28, 1997 Sec. 102(e) Date May 28, 1997 PCT Filed Sep. 4, 1996 PCT Pub. No. WO97/12664 PCT Pub. Date Apr. 10, 1997Membrane element consisting of carrier disk and membrane cushion for filtering and separating flowing media, especially in devices for filtering and separating fluids by membrane techniques. Aim of the membrane element according to the invention is the essential reduction of the losses of pressure inherent to the modules by eliminating the sharp redirections of the flow by the usual carrier disks and membrane cushions in plate modules. This is achieved by a circular guidance of the flow of the fluid to be separated between carrier disk and membrane cushion. The carrier disk according to the invention is provided with a slit-like passage so that, after a concentric, circular flow over the carrier disk and the corresponding membrane cushion, a guidance of the flow to the next carrier plate level with the correspondingly formed membrane cushion is made possible with minimal loss of pressure and almost without redirections. Carrier plate and membrane cushion are used for filtering and separating fluids in plate modules.

Abstract: A device for determining the quality of an output signal to be generated by a signal processing circuit including a radio link with respect to a reference signal is provided with a first series circuit for receiving the output signal and with a second series circuit for receiving the reference signal and generates an objective quality signal by means of a combining circuit coupled to the two series circuits, whereby a scaling circuit is disposed between the two series circuits for scaling at least one series circuit signal. The poor correlation between said objective quality signal and a subjective quality signal to be assessed by human observers can be considerably improved by disposing a discounting arrangement inside the combining circuit, which discounting arrangement should be coupled to the scaling circuit for receiving a comparison signal and for discounting said comparison signal while generating the quality signal.

Abstract: There is disclosed a process for preserving solder paste which comprises housing solder paste in a vessel which is substantially free from oxygen and moisture and is imparted with gas barrier properties. The process is preferably carried out by housing the solder paste together with an oxygen absorbent not requiring moisture for absorbing oxygen (e.g. unsaturated fatty acid compound and chain hydrocarbon polymer having unsaturated groups) and optionally a dehumidifying agent and/or an acidic gas absorbent in the above vessel and subsequently hermetically sealing said vessel. The process makes it possible to prevent the deterioration of the solder paste such as viscosity change of the solder and the formation of solder balls which affect the printability and solder reflowability, to preserve the solder paste at room temperature and to remarkably prolong its service term.

Abstract: A method and system for optimizing performance of a Kaplan turbine
power generating unit are provided wherein an optimal "N-dimensional" virtual cam is
populated with gate and blade positional settings producing maximum power output
for a set of N operating parameters. The preferred parameters include head, flow,
power generation level, physical situation of the unit, operating state of neighboring
units, trash rack loss and a parameter indicative of cavitation (such as relative
submersion level). When the system detects a unique set of operating conditions for
which optimization is needed, an iterative optimization search is performed for the best
gate and blade positional settings, which are then saved in memory (populating the cam
matrix) for subsequent use when the same operating conditions are encountered. The
optimal matrix divides parameters having ranges into range segments and treats other
parameters as having discrete states. The optimization search is preferably performed
while maintaining flow constant, and a flow characteristic search is performed to
determine candidate gate and blade settings resulting in constant flow.

second section making up the second grip (25) and, at each
side, connected to the first section (33) by means of a third
flexible section (35) and a sheet hinge (36) placed above
this. The first grip is made to swing around the hinge from a
first position where the tube seat is at a distance from the
valve, to a second position fixed by a lock making up the
second hinge, and the tube seat is close to the valve. The
second grip is, under the influence of an external pressure,
made to bend the spring and swing the first grip around a
second hinge to a third position where the tube seat engages
with the now open valve. Thereby, the dispenser head with the
discharge tube (22) can be irreversibly mounted on the
container and is automatically returned with the empty
container into the return network which thereby cannot refuse
to receive it. The dispenser head is furthermore secured
against being opened unintentionally, and it is easy to use.

data stream special flush codewords at the requested appendable points. The formatter is
also configured with the ability to insert flush codewords at positions determined by the host
interface (810) itself. The codeword that follows a flush codeword is located at a pre-determined
position relative to and after the flush codeword. Thus, appendable points are
locatable by their respective flush codewords in the compressed data stream.
