Patent EP-0655205-A3 (EP)
Title: Pressure-operated clenching press especially hydraulic press for eyelets, for punching webs and setting eyelets with a reinforced edge.
Inventor: KOCHS KARL-JOSEF
IPC: B26D5/12
Filed: 1994-08-19
Abstract: In a pressure-operated press, two plungers which are nested one inside the other are used in a cylinder housing. The one plunger serves as a beading plunger to fix an eyelet in a punched-out hole in a web. Located in this beading plunger is an internal cylinder in which the second inner plunger is arranged. The latter serves as a cutting plunger to punch the hole in the web before the eyelet is set. In order to carry out the hole-punching and eyelet-setting in a particularly efficient manner, it is proposed to provide the beading plunger with a plunger head which is sealed off in the cylinder housing and by means of which the pressure space in the cylinder housing is divided into two separate part space. The front space thus produced in the front region of the plunger head is provided with a first pressure-medium line while a second independent pressure-medium line ends in a rod space located below the plunger head. Only this second pressure-medium line is connected to the internal cylinder in the beading plunger. The cutting plunger can be provided with a head region which is guided so as to be sealed off in the internal cylinder in the beading plunger. This allows control of the pressure medium, said control being connected in both pressure-medium lines and actively causing the working stroke as well as the return stroke of the beading plunger. The pressure relief valve can only be switched into the second pressure-medium line connected to the internal cylinder and only for a limited time during the working stroke. This has a pressure-increasing effect only on the cutting plunger.

IPC: G01S7/52
Filed: 1995-04-24
Abstract: A delay generator (30) for a beamformer (12) in
a phased array ultrasound imaging system is
provided. The beamformer (12) processes received
signals from an array (10) of transducer elements
(10 1 , 10 2  ... 10 N ) to form a receive beam.
The beamformer (12) includes a delay generator (30)
corresponding to each transducer element for
delaying the received signal. The delay generator
(30) includes a delay unit (22 i ) and a delay
controller (24 i ). The delay is variable in
response to a change delay signal supplied by the
delay controller (24 i ) at discrete times during
reception of ultrasound energy. According to one
feature of the invention, the delay represents an
exact solution, within the quantization error of the
delay unit, to the delay equation for the delay at a
given steering angle, transducer element and focal
depth. According to another feature of the
invention, the delay controller (24 i ) generates a
change delay signal that steers the receive beam to
a dynamically variable steering angle and
dynamically focuses the receive beam during
reception of ultrasound energy.

Filed: 1995-09-14
Abstract: Für ein Puls-Radarverfahren wird vorgeschlagen, mehrere
verschiedene Sendefrequenzen zu benutzen und die Empfangssignale
auf eine einheitliche Zwischenfrequenz umzusetzen.
Die in mehreren Entfernungstoren entsprechend einer ersten
groben Entfernungsauflösung gewonnenen Abtastwerte werden
entfernungstorweise aus den verschiedenen Sendefrequenzen
zusammengefaßt und einer Frequenz-Zeit-Transformation unterzogen.
Dadurch ergibt sich eine höhere Entfernungsauflösung.
Überlagerungen durch Empfang von Signalen zu jeweils
anderen Sendefrequenzen oder anlagenfremden Signalen
können durch die Umsetzung auf die feste Zwischenfrequenz
in Verbindung mit einer angemessenen Filterdurchlaßbandbreite
wirkungsvoll unterdrückt werden.
