摘要:
Zum Überwachen eines Fahrwegs für Kraftfahrzeuge wird ein rückwärtiger Umgebungsbereich eines Kraftfahrzeugs mittels einer optischen Erfassungseinrichtung während einer Vorwärtsfahrt des Kraftfahrzeugs auf dem Fahrweg abgetastet. Auf dem Fahrweg befindliche Gegenstände in dem rückwärtigen Umgebungsbereich werden detektiert und ein Signal wird an wenigstens eine von dem Kraftfahrzeug entfernte Empfangeinheit übermittelt, sobald ein Gegenstand in dem rückwärtigen Umgebungsbereich detektiert wird.

A stand for a check weigher is constructed, in its basic form, from a supporting longitudinal part (1) and from two flat, plate-shaped transverse parts (2, 2'), via which the stand is supported on the ground. The invention also provides a particular design of transverse supports (13.1 to 13.4).

The invention relates to a housingless load cell whose resistance and measuring accuracy can be improved with respect to environmental influences such that at least the predominant part of the surface (12) and/or the surface (14) has a transversal path, such that water hitting the body of the load cell (1) can flow off when the load cell is in a built-in state. The angle α1 between the transversally extending part of the surface (12) and the perpendicular peripheral surface of the body (3) and/or the angle β2 between the transversally extending part of the surface (14) and the peripheral surface of the leg (4) is respectively greater than 90° and is, more particularly between 93° - 120°. A housingless load cell comprising a compensation electronics system is provided in one of the transversal holes (7). Finally, a load cell is further developed such that the peripheral surface of the leg (4) comprises at least one essentially perpendicular groove (24) forming a rotational lock piston with a protruding element on the lower plate.

The invention relates to devices for measuring dynamic loads applied to a roadway by road traffic. The object of the invention is an electromagnetic loop sensor which can produce a signal in response to pressure applied to the surface thereof. The sensors comprises at least one electromagnetic loop (22) radiating an electromagnetic field, and a conductor hood (20) forming an interface between the surface on which the pressure is to be applied and the electromagnetic loop. The interface stops the electromagnetic field radiated by the loop.

This invention relates to a method and apparatus for automatically batching objects into portions, comprising conveying and weighing objects. An appropriate bin for each of the weighed objects is selected, wherein each bin is provided with a weighing means. Accordingly, the total portion weight is periodically registered. By mean of comparing the potion weight with the summed object weight in that portion an appropriate bin can be selected for forthcoming objects.

The invention concerns an electronic processor for use in processing cash transactions comprising an electronic processor and a database. The processor has: 1) an interface for receiving a request from a member using the system for generating a coded number representing a desired cash value to be purchased at a remote terminal, for receiving a request that a number previously allocated may be redeemed, for transmitting to the remote terminal a generated number and for transmitting a message to a terminal indicating that a received request for redemption is valid; 2) a validation section for determining whether or not received requests are valid; 3) a number generation section for generating a coded number in response to a valid request; and 4) a storage section for storing each number generated in response to a valid request in a first table of the database and for storing the total value of cash represented by issued coded numbers which have not been redeemed in a Fund table and for transferring a coded number the redemption of which has been validated to a second table and decrementing the total value in the Fund table by the value represented by each coded number for which a validated redemption request is received so that every coded number issued can never cause more than one increase in the value represented in the fund table and every coded number redeemed can cause only one decrease in the stored value.
摘要:
The invention relates to a device for conducting a weight measurement in centrifuges for the separation of suspensions in their solid and liquid components. Said device contains a machine housing (2), a rotationally mounted drum located in said housing, and a filler tube (11) leading into the drum. Said drum contains the suspension and the filler tube is used to feed the suspension into the drum. The machine housing is pivotally arranged around an axis of rotation. A dynamometer element (19) senses the deviations of the machine housing about the axis of rotation resulting from varying suspension fill degrees in the drum or varying amounts of dehumidification of solid suspension components according to weight. Said deviations are indicated by a device (35) which displays measured values. A line (10) is provided for generating an overpressure or a depression in the drum. The line of action (50) of the force generated in said line on the basis of over pressure or depression is guided so that it cuts the rotating axis (14) of the machine housing or a sensor for reading the pressure in the drum is provided. Said sensor corrects the measured value and corrects the value indication according to pressure.
