Title: Non-coherent 6-port receiver
Inventor: BRANKOVIC VESELIN
IPC: H04B1/26
Filed: 1998-06-18
Granted: 2008-11-25
Abstract: According to the present invention a method and a receiver for high-frequency signals is provided. The receiver comprises a power divider (4) to divide a modulated RF  input signal in at least two branches. At least one delay line (5, 6) provides for a delay of the branches relatively to each other by a predetermined delay constant. A  calculation circuit (7, 8) calculates at least three power levels based on combinations (12, 13, 14) of the two branches of the input signal relatively delayed (5, 6) to each other. A  processing means (10) calculates the phase and the amplitude of a complex signal representing the relation between the two branches of the input signal relatively delayed to each other, on the basis of the said at least three power levels (8).   The invention therefore provides for a direct 6-port receiver based on non-coherent detection. The concept of the invention is inherently cheap and features high integration ability and low-cost processes. Ideally the whole RF front end can be placed on one chip.

Abstract: Ink decoration applied to bottles during a dwell period at decoration stations of an intermittent motion decorating machine is cured during a dwell period while the bottles dwell at curing stations, each downstream of a decorating station. A bottle rotator at each curing station is joined by a tie rod to drive a bottle rotator at a decorating station. An alternative embodiment provides separate drive motors for a decorating and a curing station and control of the motors is provided by the same control signal to rotate bottles during a dwell period. Restraint rails and rotators at all decoration and curing stations prevent loss of an established orientation between each bottle and each decoration screen at each decorating station. The established orientation can be established by an indexer at the bottle receiving end of the decorating machine.

Title: Method and apparatus for verifying the position of a motor driven machine element
Inventor: CATANZARO JOHN C
IPC: G05D3/20
Filed: 1998-10-16
Granted: 2006-04-11
Abstract: A method and apparatus for verification of the linear position of a machine element driven by a motor is provided. The actual position of the element is detected and compared to an expected position. When the two positions differ from each other by more than a predetermined tolerance value for a predetermined amount of time, an error signal is generated which deactivates the motor and generates an alarm for the machine operator. Preferably, the linear position of the axis is detected by a transducer and the expected position is determined by detecting the rotary position of the motor through the use of a resolver, which is then converted to a linear equivalent through the use of the gearing ratio. The method and apparatus can detect faulty machine conditions and thereby prevent machine malfunction and/or machine damage. Preferably, the method and apparatus are used to verify the position of machine elements in an injection molding machine.

Abstract: The dispenser enables a multiplicity of doses of a substance in powder or granular form contained in a reservoir to be dispensed in succession. To form a dose a shaft must be rotated relative to a part of the dispenser, the shaft having to be substantially vertical while the dose is being formed.      Between the shaft and said part of the dispenser there is provided a joint which prevents relative rotation if the shaft is not substantially vertical, or which although allowing relative rotation enables a signal to be emitted which can be sensed by the user. In particular the dispenser can be a multi-dose inhaler for medicaments.

A pump having an NPSHR less than the NPSHA may be used for drawing slurry into the high pressure feeder from the steami ng device, or a pump may be disposed between the steaming device and the high pressure feeder for forcing slurry into the high pressur e feeder through a conduit including a radiused elbow. The steaming is practiced at a pressure of 5 psig or less, preferably substantially atmospheric steaming is practiced. The pulp produced typically has strength properties at least about 10% greater than the pulp produced fr om material where it is steamed and slurried at temperatures in excess of 110 .degree.C.

Dans un mode de réalisation, un réseau de diffraction disperse un faisceau optique en composantes de différentes fréquences spectrales ou longueurs d'ondes, qui sont collimatées par une lentille. Un miroir est placé à une distance d'une longueur focale de la lentille, et la modification de densité de trait du réseau, l'angle d'entrée de réseau, l'angle de sortie de réseau, et/ou l'inclinaison du miroir produisent un changement dans le groupe optique et le retard de phase. L'appareil permet de détecter le groupe optique et le retard de phase par balayage de l'angle du miroir. Dans d'autres modes de réalisation, ce dispositif permet d'effectuer un balayage de retard optique sans employer d'éléments mobiles.
