Patent EP-0020920-A1 (EP)
Inventor: NAVIN JAMES P
IPC: G01G19/414
Filed: 1980-04-23
Abstract: This disclosure relates to a system for weighing one or more articles, automatically computing the price of an article, and printing data including the price on a label that is normally attached to the article. The system is designed for use with a variety of different articles or commodities, and each commodity is assigned a code or key number. The system includes a number of memory units, and information relating to each commodity is stored in the memories. The information may include price per pound, tare weight, commodity name, etc. When a particular commodity is to be weighed, the key number associated with the commodity is inserted by an operator into the system, thereby withdrawing the information from memory for use in computing the total price and in printing a label. The system may further include means for formulating a universal product code (UPC) marking and printing the code marking on the label.

Abstract: A secondary seal arrangement for use in a rotor to ensure the retention of the fluid sample within the test tube cavity of the rotor during high speed centrifugation in an ultracentrifuge. The secondary seal arrangement acts in cooperation with both a spacer member (12) over the centrifuge tube (58) and a sealing plug (16) for the rotor cavity to provide a seal of the cavity over the test tube (58) to reduce the possibility of escape of any fluid which may inadvertently exit the centrifuge tube (58) itself. The secondary seal (14) is positioned within the rotor tube cavity above the capping seal for the centrifuge tube to provide a closure of the rotor tube cavity above the centrifuge tube.

Abstract: A system and method for detecting the presence of two or more overlapping documents using a capacitive sensing device through which the documents are arranged to pass. A document sensing signal (42) generated in response to the detection of one or more documents is delayed by the capacitance of the sensing device which varies according to whether one or more than one document passes therethrough. The delayed signal (54) is applied to comparison means (56) together with the original document sensing signal (42) and a multiple document detect signal (70) is produced when the output of said comparison means (56) is indicative of a delay in excess of a certain amount.

Abstract: A rotor (2) rotates in a stator (1). It drives or is driven by vanes (6), the centre point being that of the rotor (CR) and a tangent point (TR) of the latter being different from the tangent point (TS) of the stator. The vanes are guided by means of running rollers (8) fixed to the bottom of the vanes and, during assembly, engaged in a running track (7) formed in the side walls, thus eliminating centrifugal friction. Moreover, seated in a recess of the vanes are two vanes guide rollers (5) which run in the receptacle (4) formed in the rotor, thus eliminating rolling friction. The profile of the running track, shown here as circular with as its centre point that of the stator, must be in a relation to the inner profile of the stator, whatever this may be. End sealing is obtained by a set of standard sealing rings. <IMAGE>

Abstract: There is provided a landmine which comprises a casing, an ignition means (25), a de-masking charge (23), a detonator charge (24) and an explosive charge (26). The ignition means (25) comprises an electronic timing unit (28), an electric motor (20) and an operating shaft (30) which can be locked mechanically by two safety means (11,12) in a first angular safe position and is driven by the motor (20) via a transmission gear and which allows activation of the de-masking charge (23) and the detonator charge (24) in a second angular live position. The speed of the motor (20) exceeds 5000 r.p.m. and is preferably 15000 r.p.m., while the speed at which the operating shaft rotates is of the order of 1/40 r.p.m. 
     When the mine has not exploded within a given time period, the electronic timing unit (28) restarts the motor (20) for rotation of the operating shaft (30) into a third angular re-safe position, which can be identical to its first angular position. During its rotation, the operating shaft (30) can also activate one of the safety means (11,12) for locking shaft rotation, and means for marking on the mine the condition of the mine, i.e. whether the mine is safe or live, and for marking above the ground the position of the mine in its re-safe state.

Abstract: An eine als dosimetrischer Sekundär-Eichstandard geeignete Ionisationskammer, sind besondere Anforderungen, insbesondere an die Langzeitstabilität, an die Unabhängigkeit von der Photonenenergie und damit an die Luft-, Gewebe-bzw. Wasseräquivalenz des Kammermaterials, sowie an die Unabhängigkeit von unkontrollierten veränderlichen Meßfehlern, wie sie z.B. durch atmosphärische Störungen bedingt werden können, gestellt, Durch die Verwendung eines Grundstoffes, bestehend aus Polyacetal eventuell mit bis zu 20 % Polytetrafluoroethylen gemischt, dem verschiedene geringe Mengen von Zuschlagstoffen zugesetzt werden für die Herstellung der maximal 3 mm dicken Kammerwand, wird sowohl die erforderliche Materialäquivalenz als auch die mechanische Langzeitstabilität gewährleistet. Durch den an der Innenfläche der Kammerwand ausgebildeten leitenden Überzug, insbesondere in Form einer Aluminiumschicht mit weniger als 0,05 mg/cm², wird die für die weitgehende Energieunabhängigkeit erforderliche Kompensation der Absorptionsverluste für niederenergetische Photonen erzielt. Durch eine spezielle Ausführung der Außen- und Innenelektrode, sowie des Schutzringes im Halsteil der Ionisationskammer wird eine weitgehende Reduzierung der z.B. durch Luftfeuchtigkeit bedingte Feldveränderung und damit der veränderliche Fehler des Ionisationsstromes erzielt. Zur Überprüfung, ob die Ionisationskammer noch die an sie für die Verwendung als Sekundär-Eichstandard gestellten Forderungen erfüllt, wird ein, eventuell auch jeweils ein verschiedener, Prüfstrahler in das Zentrum der Ionisationskammer für die Dauer der Prüfung eingebracht.

Abstract: A data processing system for error processing and an error processing method, which system includes a main memory (M), an information processing unit (A), an error processing unit (EP) and an alternate memory. When an error arises in a portion of the main memory, corrected information is stored in the alternate memory. Then, under the control of the error processing unit (EP), the alternate memory is employed instead of the malfunctioning portion of the main memory. The alternate memory is adapted to be used only when the error is a fixed error or a burst error, in order to avoid a system shut-down caused by fixed- and soft-errors or burst- and soft-errors which occur during information processing. The alternate memory, therefore, is not used in a case where the error is a soft error. This imparts an additional advantage in that the size of the memory is reduced.

Images of the subject corresponding to different luminances are converted severally into video signals by a television camera (13). A signal component within a given level range is extracted from each of these video signals by a limiter (21). The signal components of the video signals are composed into video data to be supplied to a display (27). The display (27) indicates the video data as an image with proper contrast.

Abstract: A method and apparatus for controlling a mechanical system having to perform cyclic operations with momentary stoppages of a movable element at positions precisely determined by means of stops. According to the invention, the movable element (1) being driven by an electric motor provided with a brake, the electric motor being connected to a power supply by means of a switch, in order to obtain a precise stoppage position on one of the stops (11), the method comprises the following steps: - braking of the movable element (1) so that the latter arrives at the stop (11) with a speed of virtually zero, the motor still being supplied; - cessation of the braking, the element then being at rest but the motor still being supplied; - deformation of at least one elastic member (8) by means of the torque produced by the motor still being supplied; - disconnection of the supply to the motor after locking the rotor of the latter, so that immediately thereafter the elastic member (8), by tending to return to its initial shape, exerts a restoring force which maintains the movable element (1) against the stop (11).
