Abstract: In a process for checking the solidity of vertically anchored masts, rising traction and compression forces F which can be sensed by a force sensor are introduced into the mast above its anchoring in order to load the mast with opposite bending moments. At least one displacement sensor supported against the mast above its anchoring measures the lateral deflection S of the mast caused by the bending moments. The measurement values for the force F and deflection S generated by the force and displacement sensors are separately processed in an evaluation unit relative to the functions f = F(S) or f = S(F), based on the curve of functions f1 in the event of a pressure load and on the curve of functions f2 in the event of a traction load. If the rising part of the curve of functions f1 deviates from the rising part of the curve of functions f2 or from corresponding reference values when the mast is elastically deformed, this is taken as a criterion for crack formation in the mast (1). A device for checking the solidity of vertically anchored masts has a force application unit (5) for applying rising traction and compression forces F to the mast (1) which can be sensed by a force sensor ( 7) and for loading the mast with opposite bending moments, at least one displacement sensor (8) which can besupported against the mast (1) above its anchoring (2) to measure the lateral deflection S of the mast caused by the bending moments, and an evaluation unit (9) to process the measurement values for the force F and deflection S generated by the force and displacement sensors (7, 8) relative to the functions f = F(S) or f = S(F). The evaluation unit determines if the rising part C of the curve of functions f1 deviates from the rising part of the curve of functions f2 or from corresponding reference values and considers this as a criterion for crack formation in the mast.

Abstract: Cette invention concerne un rouleau à peinture bifurqué et un procédé d'utilisation dudit rouleau à peinture. Le rouleau à peinture est un outil à main équipé de deux rouleaux applicateurs présentant chacun une surface pelucheuse qui sert à ramasser la peinture et à l'étaler. Les rouleaux applicateurs sont séparés et disposés latéralement l'un par rapport à l'autre et pivotent indépendamment l'un de l'autre. Le rouleau à peinture bifurqué s'accompagne d'un bac à peinture lui-même bifurqué. Le bac à peinture comprend deux compartiments pouvant contenir chacun une peinture ayant une caractéristique différente. Les deux compartiments sont isolés l'un de l'autre par un séparateur qui empêche les peintures ayant les caractéristiques différentes de se mélanger. La partie distale de l'outil à main comporte une fente ouverte dans laquelle on insère le séparateur de façon à pouvoir égoutter les rouleaux applicateurs dans leur bac respectif. Suivant une autre configuration, on peut monter sur l'outil à main des tubes servant à alimenter en peinture les rouleaux applicateurs. Un procédé de peinture comprend les étapes consistant à appliquer sur une surface une peinture ayant une première caractéristique, puis une peinture ayant respectivement une deuxième et une troisième caractéristiques. On applique une feuille plastique sur ladite surface puis on la retire immédiatement après l'une ou l'autre étape ou les deux étapes de peinture. L'outil à main et le procédé de peinture fournissent une méthode rapide et simple pour obtenir un effet identique à celui qu'on obtient avec la peinture à l'éponge ou au chiffon. Il est particulièrement préféré d'employer une texture pour la première caractéristique et, pour les deuxième et troisième caractéristiques, d'employer une deuxième et une troisième matières micacées qui donnent un effet nacré contrasté.

Abstract: This invention relates to arrangements for interconnecting a plurality of stand-alone switches by data and communication channels (the latter typically used for communicating voice signals) in such a way as to make the plurality of switches act as if they were one switch. According to one arrangement of the invention, a method of controlling a plurality of associated key telephone stations within a set of the stand-alone switches is disclosed. The method includes the steps of grouping the set of stand-alone switches into a symbiotic network, and transmitting first display control data messages, over the data network, to second ones of the switches connected to the stations to control displays of the stations. The method also includes the steps of transmitting display control messages fromthe second switching systems to the stations based on the receipt of the first message in the switching systems and transmitting, over the data network, a request to the first switches to establish a connection from the line or trunk to the stations. The final step involves establishing a connection from the incoming trunk to thestations. Advantageously, such an arrangement provides a convenient way of achieving the advantages of a giant switch without requiring the capacity of such a switch and without requiring the geographic concentration of traffic necessary to keep the links to a giant switch reasonably short. Advantageously, a virtual symbiotic network provides an economical and flexible solution to the problem ofproviding services such as wide area Centrex.

Abstract: A relay is described to facilitate communication through the telephone system between deaf people and hearing people. To overcome the speed limitations inherent in typing, the call assistant at the relay does not type most words but, instead, re-voices the words spoken by the hearing person into a computer operating a voice recognition software package trained to the voice of that call assistant. The conversation-type flow of communications achieved by this type of relay enables the design of a new class of interpreters for the deaf.

Abstract: A removable and replaceable filter and filter holder is mounted within a mop cleaning bucket to receive dirt settling under gravity from the contained liquid with the dirt collecting in, and passing through so as to be trapped below, the filter and its holder.  The holder is a rigid or substantially rigid perforated support structure spaced above and below the dirt receiving filter. In one embodiment, the holder is supported in the bucket in spaced relationship to the bottom of the bucket and protects the filter. The filter is a thin, sturdy, semi-rigid and floatable member with many holes so soiled water passes through and collects in the bottom of the bucket. The construction of the filter can be selected depending upon the material (grease sludge, dirt, oil, soot, or food particles) to be mopped up. The combination of the filter and filter holder blocks or dampens turbulence and prevents sediment from being stirred up in the bottom portion of the bucket. In the absence of the present invention, sediment could rise upwardly and mix with cleaner water above the filter and filter holder and which is reserved for mop cleaning and rinsing.
