Title: Nondetachable press fit connector for thin-walled pipes
Inventor: UNEWISSE HEINZ
IPC: F16L13/04
Filed: 1990-01-15
Abstract: Abstract of the Disclosure A press fit connector for nondetachably coupling thin-walled pipes formed of titanium or a titanium alloy and intended for conveying corrosive liquids is fabricated from titanium or a titanium allow.  The connector includes, on its continuous wall, a bead shaped end which defines a hollow and within which a sealing ring is disposed.  An end section of a pipe is slidably receivable within the connector and the bead-shaped end is then clamped between the opposed jaws of a pressing tool to deform the bead-shaped end, thereby pressing the sealing ring against the outer periphery of the pipe and securing together the connector and pipe in form-locked, force-locked and liquid tight relation.          The connector may also include a stop for limiting sliding movement of the pipe end section into the interior of the press fit connector beyond the stop.

Title: Multiple-modulator fractional-n divider
Inventor: MILLER BRIAN M
IPC: H03L7/183
Filed: 1990-06-19
Abstract: ABSTRACT A fractional-N type frequency synthesizer includes a frequency divider having a selectable integer divide number which is periodically temporarily altered to provide an average rational divide number for the frequency divider. A number of modulator circuits coupled in cascade fashion provide a zero sum modulation signal which varies the value of the frequency divider divisor value such that the net change in divisor value due to the modulation signal is zero  thereby  reducing phase  noise  resulting  from the temporary altering of the integer divisor value close to the frequency synthesizer carrier frequency.

Title: Method of restoring the correct cell sequence, particularly in an atm exchange, and output unit therefor
Inventor: SCHRODI KARL
IPC: H04L12/56
Filed: 1990-12-20
Abstract: State of the art (not public): In order to load an ATM switching network as evenly as possible (even in the short term) and thereby minimise cost, the consecutive cells of one and the same connection are switched through to the exit via as many different paths as possible. 
<??>Technical problem: Reciprocal overtaking of consecutive cells must be avoided or corrected. 
<??>Fundamental principle: Each cell is held at the output until it is ensured that no preceding cell can still be temporarily stored in the switching network. Before the cell is forwarded, a check is carried out to ascertain whether, among the cells leaving the switching network at a later stage, a preceding cell is still present which is to be forwarded before it. 
<??>Implementation: Sequence numbers are assigned to the cells on the input side (either on an individual connection basis or not). On the output side, a buffer memory (1) is provided which is operated at least partially (1, ..., d) in the manner of a shift register and thereby produces a predefined delay. Before the output of a cell, at least the part of the buffer memory which is operated in the manner of a shift register is interrogated to ascertain whether a cell registered at a later stage is to be output earlier. If it is, the two cells are exchanged.

Abstract: Abstract An arrangement for the waveguide-free light or infrared transmission ofelectrical signals, especially sound performances, digital signals, measured values or moving television pictures, enables the transmission of the signals between two devices of the same kind of the arrangement at the same time in both directions. A plurality of such arrangements can be operated simu1taneously side by side. The optical radiation between the two devices propagates directly or through reflection, dispersion or diffraction. The circuit expense can be kept especially low by suitable selection of the transmission parameters since for each device only one frequency determining oscillator is necessary not only for the emission but also for the reception.
