Patent EP-0654327-A1 (EP)
Inventor: FEITEN WENDELIN DR
IPC: G01B7/004
Filed: 1994-11-08
Abstract: The invention describes a device for the exact determination of the position of a flexible actuator, for example a robot arm which can be expanded, contracted and bent as desired. This robot arm is equipped on its flexible limbs with vibration pickups, for this purpose. Along these vibration pickups a vibration carrier, for example a steel cable, is displaceably guided through guiding eyes in which these vibration pickups are fitted. This steel cable is then excited, for example with a vibration, such as for example ultrasound or mechanical vibrations. This vibration propagates along said vibration carrier at its speed of propagation. From the propagation times of the vibration to the individual vibration pickups, the distance between the respective vibration pickups is determined via an evaluating unit to which all the vibration pickups are connected. Such a vibration carrier can be, for example, a steel cable which actuates an actuator. In this case, the speed of propagation of the vibration also depends on the mechanical pretension of this steel cable. In order to be able to determine this speed of propagation in dependence on this tension, it is furthermore provided in the invention that the speed of propagation be measured along a cable piece of constant length by measuring the propagation time there. This speed of propagation of the vibration determined there then forms the basis for further calculations of the part-lengths between the other vibration pickups on this steel cable. Vibration pickups may be of capacitive or inductive type. What is important is that only part of the vibration energy is dissipated from the steel cable so that there is still sufficient vibration energy available at the end of the actuator for the vibration pickups situated there. Areas of application of the invention are, for example, domestic robots or industrial minirobots, or autonomous vacuum cleaners. <IMAGE>

Abstract: A pressure switch particularly adapted for use with high pressure fluid is shown having a frusto-conical support surface in the form of a protuberance (121) formed at the center of a surface of a piston guide member (12). A stretchable diaphragm cap member (14) generally in the shape of an inverted V is closely fitted on the protuberance of the piston guide member as well as the head (111b) of a piston member (111) received in and projecting out of bore (120) formed centrally through protuberance. The outer thickened peripheral berm of the cap member is inserted into a recess (102e) in the wall defining an enlarged portion of the bore (102) which in turn opens to a cavity (103) of the upper housing (10) in which piston guide member is disposed. The cap member serves to seal the fluid passage side of the switch from the remainder of the switch. In several embodiments a ring is placed between the cap member and the conical support surface to reduce sliding friction and to prevent extrusion of the cap member material into a gap formed between the piston member and the piston guide bore.

Abstract: A method and apparatus for delivering a cryogen in which a cryogen is stored and delivered in a cryogenic storage facility having three tanks (12,14,16). Each of the tanks is filled with the cryogen in a subcooled liquid state to wash contaminants down toward a bottom region thereof. Thereafter, a minor stream composed of superheated vapour is introduced into the bottom region of each tank to pressurise each tank. A major stream of the superheated vapour is then introduced into each tank to form scrubbed cryogenic vapour in the head space region thereof which is used in forming the product stream. Each tank is subsequently used to dispense the cryogen to a vaporiser (102,104,106) to form the superheated vapour which is in turn divided into the major and subsidiary streams. The foregoing operations are preferably conducted the three tanks as an out of phase cycle such that one tank dispenses the liquid cryogen to the remaining tanks as the major and subsidiary streams and after having dispensed the cryogen, each tank is refilled which again substantially clears the top head space region thereof of contaminants.

Abstract: A wheeled vehicle such as a wheel-chair has motor-driven wheels (1) and freely rotating swivel wheels (11, 11'). The motor-driven wheels (1) have shafts fixedly arranged in the vehicle and they are driven individually for steering the vehicle. In order to reduce those instabilities which can arise in the movement of the vehicle, one (11') of the freely rotating wheels is provided with a direction or steering control, so that it can be given a suitable angle in relation to the vehicle and to the movemenet direction thereof. For some movement states the angular direction control can be deactivated so that the freely rotating swivel wheel (11') can adjust itself freely in the usual way. For achieving the angular direction control of the swivel wheel (11') a chain or belt (21) runs about the swivel shaft (13') thereof and it also passes over a wheel (22). This wheel (22) is driven by an electric steering motor (19) through a not self-braking or not irreversible worm gear unit (23). The system steering control motor (19), reduction gear unit (23), chain or belt (21), is as seen as a unit, reversible, which allows a forced control of the angular position of the swivel wheel (11'), when the motor (19) is actively driven when feeding electric current thereto, and that the swivel wheel (11') can adjust itself freely to an arbitrary angular position when no current is fed to the motor (19).

Abstract: A multiple layer printed circuit board (60) and a method of manufacturing multiple layer printed circuit boards (60) which incorporate integral edge shielding in combination with top and bottom shielding to effectively provide a sandwich arrangement within a Faraday Cage. Electromagnetic emissions radiating from an outside surface of either the top or bottom shielding layer are substantially reduced. In one structure, a multiple layer printed circuit board having a sandwich arrangement which includes at least one inner conductive layer (70) for providing a ground plane disposed between the outer shielding layers, the inner conductive layer (70) being electrically connected directly to the edge shielding means and hence to the outer conductive layers (20, 22). The larger and more continuous surface area provided by the direct connection to the edge shielding effectively provides an electrical connection having a low inductance and hence in operation results in all ground planes having a more constant non-varying potential.
