Granted: 1998-12-22
Abstract: A process and apparatus are disclosed for controlling the flow of operations in electroplating plants with horizontal throughflow in which the parts to be electroplated, in particular plate-shaped parts, pass through the plant in succession and are electroplated by means of currents applied by anodes. In order to prevent undesirable, increased precipitation on the front faces or edges of parts to be electroplated which follow each other at undesirable distances apart, or at least to reduce this precipitation to an acceptable level, the position of the parts which pass through the plant in succession and/or the distances between these parts are detected and the application of the electroplating currents is controlled as a function of these positions and/or distances by switching the anodes on and off, in such a manner that the flux density is approximately the same in all regions of the parts.

Title: Load measuring system for refuse trucks
Inventor: BOWMAN ALLAN
IPC: G01G19/08
Filed: 1992-08-11
Granted: 2002-07-02
Abstract: A method for determining a weight of material being emptied from a container is shown. The container is lifted to and lowered from an emptying position in a lift empty and lower cycle by an arm which has at least two sensors mounted on it. The method includes selecting at least one measurement position, calibrating the sensors by recording the respective outputs from each of the sensors for both an empty arm and for an arm lifting and lowering a calibrating weight. The outputs recorded for the calibrating weight can then be subtracted from the outputs recorded for the empty arm. Then, an unknown load can be lifted emptied and lowered with the output of the sensors being similarly recorded at the measurement position. By subtracting the output recorded during the lifting portion of the cycle for the unknown load from the output recorded during the lowering cycle for the unknown load a change in output far each sensor at the measurement position can be obtained. The change in output of the sensors can then be compared to the change in output recorded for the calibration step and a weight value calculated. In another aspect of the present invention an apparatus is disclosed having at least two sensors mounted to a sensing portion of an arm. Output from each sensor i.s independently recorded and used in obtaining calibration values and actual weight values.

Abstract: Distributeur (60) de billets pouvant être utilisé pour toutes sortes de billets (68), en particulier des billets de loterie (66) et autres billets présentés en bandes pliées en accordéon (64). Le bout de tête (124) de la bande de billets est dirigé contre une butée courbe (116) qui fait plier le premier billet (68) le long d'un pointillé (148) et le fait sortir par la fente (44) du distributeur (60), en angle par rapport au reste de la bande (66). Le billet (68) peut être détaché aisément en suivant la ligne de pointillé (148), puisque le reste de la bande (66) est retenu fermement dans le distributeur (60). Une barrière pivotante (92) permet de fermer la fente (44). Elle s'escamote pour permettre le passage de la bande (66) et sert également à diriger le billet (68) dans la fente (44). Le distributeur (60) offre l'avantage d'un faible encombrement, d'un fonctionnement précis et d'une utilisation simple et facile. Il n'y a aucun risque que les billets soient coupés en deux ou qu'ils soient déroulés plusieurs à la fois sans que le paiement requis n'ait été introduit. On peut fabriquer une machine distributrice de billets (20) en assemblant un ou plusieurs distributeurs (60) selon cette invention avec un appareil récepteur de monnaie. Une même machine distributrice de billets (20) peut être utilisée pour distribuer différentes sortes de billets (68).

Granted: 1999-05-11
Abstract: Data transfer apparatus (211,213) for a radiotelephone peripheral using a time multiplexed data bus for communication with a bus master of the radiotelephone (201) couples peripheral devices external to the radiotelephone (201) and other user information inputting devices, such as a handset (203) for a cellular mobile radiotelephone, to the radiotelephone's central processor and speech processor (207). The data transfer apparatus generates time slots in frame formats in which the information is sent over the data bus. The entire message, information bits and the header, sent in a time slot from a peripheral device to the bus master is used to determine bus contention. Bus contention resolution during the start-up of data bus operation sets the priority with respect to other data transfer apparati with which a peripheral device's data transfer apparatus is able to access the bus during normal operation.

Abstract: Label applier of an automatically operated label applying system is selectively controlled by a machine operator to rotate self-adhesive labels to any of a variety of different angular orientations in response to interception of a driving bevel gear at a predetermined position.  A driven pinion gear which carries a vacuum wand with a vacuum gripper on an end thereof rotates the wand and label to any one of 90, 180 or 270 degrees, depending on which of three intercepting pins is activated under selective control of an operator.  In the event no intercepting pin is activated, the drive gear rotates through the same angle as its supporting shaft and effectively avoids rotation of the driven gear and turning of the label.  The label applier is remotely controlled by automatic means, thereby avoiding the necessity to make manual changes to the applier each time a new angular orientation becomes necessary.
