Abstract: A linear potentiometer, having a longitudinal housing with a resistance path and with a wiper guided by a push rod sliding therein. The push rod is supported at its entry into the housing of the potentiometer via a slide bearing which contains an elastic ring element, preferably an O-ring. This ring element embodies the sole connection between a stationary outer bearing and an inner bearing which is movable in a swinging manner relative to the outer bearing because of the elastic connection. The push rod slides in the inner bearing. The inner and outer bearings, by means of opposing annular grooves, receive the elastic ring element connecting them.

Title: Automatic twine wrapper for round bale forming machine
Inventor: VAN DEN BOSSCHE BART
IPC: A01F15/14
Filed: 1984-11-21
Granted: 1988-10-27
Abstract: The baling machine has automatic control including a time delay coupled to a detector detecting whether the filament is around the bale or not. The delay introduces a pause in the dispensing process if no filament is detected. When the filament is present, dispensing continues uninterrupted. The control stops the interruption as soon as the detector indicates the presence of filament. The control also resets the dispenser. The detector senses whether the filament is moving or stationary and comprises a piezoelectric pickup acted on by a filament between the filament container and the dispenser.

Abstract: A method and an arrangement are specified by means of which the transmission of data between a remotely positioned terminal (10) and a computer (14) can be transmitted in a protected manner. A protection unit (12) allocated to the terminal (10) transmits an access request via a telephone line to the computer and subsequently transmits via the telephone line in plain text a first message which contains an identification number allocated to the identification unit (12) and encodes a second message consisting of a personal identification character chain which is input by a terminal user into the terminal, of a first internal identification word which is automatically generated by the protection unit and of the telephone number of the calling telephone. The protection unit subsequently interrupts the connection to the computer. It waits for a call back from the computer (14) and, in this case, transmits via the telephone line a fourth message which acknowledges the call back and encodes a fourth message which contains the data to be transmitted. <IMAGE>

Abstract: Method and device for completing the automatical matching of panels to be cut in patterned fabrics to ensure that the design for each one of the panels to be cut is in its correct position. After defining a series of matching points on each of the patterns and recording as digital data in a memory the matching relationships for each one of these points are defined and stored as matching information in the memory, the matching itself is carried out using a TV-camera (12) installed on the cutting machine (11), capturing images from any point of the fabrics being spread in connection with a digital image processing unit which, by processing the images captured, fix the real position of the design on the fabrics. Matching device, integrated marking and a cutting system are connected in such a way to process the image information with the predicted matching relations to generate an adjustment to the position initially assigned to each panel - in both directions and in orientation - and guarantee a perfect cut of the panels.

Abstract: The method and the device described are intended to avoid the dissipation of electrical energy that occurs in the coil of a stepping motor when the coil is short-circuited permanently between two drive pulses. The method comprises short-circuiting the coil at the end (t1) of the drive pulse, then putting it on open circuit at the instant (t2) when the current (Ic) flowing through it during the short-circuit becomes zero, and short-circuiting the coil again at the instant (t3) when the voltage induced in it by the rotation of the rotor while the coil is on open circuit becomes zero or reaches a predetermined value (Ud). The device is designed to carry out the method. The invention is applicable to the control of stepping motors of the type for instance that are fitted in electronic timepieces having a hand display.

Abstract: An electric door opener with a changer freeing or blocking a latch is described, which changer is detachably engaged with an electromagnetically operable inner armature. An electromagnetically controllable locking device prevents disengagement of the inner armature from the changer, e.g. as a result of an impact. The locking device has a locking lever provided with a detent and a control edge. The lever engages a corresponding projection on the inner armature. An outer armature acting on the control edge initially deflects the locking lever to overcome the locking action and, after a predetermined forward movement, drives the inner armature to release the changer.

Abstract: A combined air-rubber spring has a load-bearing plate 8 and a bell-shaped rubber component 1 which supports the load-bearing plate 8, consists of a hollow-cylindrical side wall 2 and an end wall 3 extending essentially radially, and is closed in a sealed manner by a base plate 4, extending radially, which, together with the side wall 2 and the end wall 3 of the rubber component 1, delineates a pressure chamber 5 which can be filled with air, the end wall 2 of the rubber component 1 consisting of a central, circular section 6 and an annular edge section 7 arranged coaxially about the central, circular section 6. To increase the vibration-damping and shock-absorbing effect of the spring, and to prevent failure of the spring in the event of an overload, the annular edge section 7 of the end wall 3 of the bell- shaped rubber component 1 is constructed as a truncated cone and one or more feet 9 project in the axial direction into the pressure chamber 5 from the central circular section 6 of the end wall 3 of the bell-shaped rubber component 1, the free ends of which feet 9 are at an axial distance from the base plate 4 when the spring is in the undeformed state, and the other ends thereof are firmly connected to the load-bearing plate 8. The pressure chamber 5 can additionally be partially filled with fluid 14, into which the feet 9 dip with a radially broadened section 15, arranged in the region of their free ends, to improve even further the damping characteristics of the spring.

Abstract: A fabrication process for providing an epitaxial layer on a silicon substrate and over predefined insulator-capped islands (18) which forms a self-aligned contact window in the epitaxial layer. Application of the method to a three-dimensional dynamic random access memory (DRAM) device structure is shown, with an access transistor (80, 84, 98) formed in monocrystalline silicon (30) stacked on top of a trench capacitor. A fabrication method therefor is shown wherein the contact window (52) for the source-to-trench connection is formed by self-aligned lateral epitaxial growth, followed by a contact-connection formation step using either a second epitaxial growth or a CVD refill and strapping process. The invention can be further applied to other device structures using the described principles, and more specifically to an inverter structure having the driver device stacked over the load-resistor as another example, which can be used as a basic building circuit unit for logic circuits and static-RAM cell.

Abstract: Infusion of a drug, e.g. a chemotherapeutic agent is optimised via retrograde perfusion through the venous side of the vascular network to a selectively determined portion of a solid tumour. Monitoring and regulatory capability are provided for controlling the outflow of the drug and thus for controlling the dose rate, the duration of exposure of the drug, the leakage factor, and the level of systemic toxicity, all critical factors in the successful treatment of tumours. A feedback loop comprises two concentric balloon catheters capable of extensive maneuvering and selective placement within the venous drainage of the vascular system, creating a third in-vivo space for repeated perfusion of the selected portion of a diseased organ as often as desired.  During treatment, the patient's response and reactions are observed and monitored by a computerised axial tomography scanner and video monitor.
