Patent CA-2107643-C (CA)
Inventor: SCULLER STEVEN J
IPC: B41K1/02
Filed: 1993-10-04
Granted: 1997-09-30
Abstract: In  a  hand  stamp  mount  device  especially suitable for a preinked stamp impression member that can give great numbers of imprints, the downstroke distance of a substantially rigid,  non-rotatable assembly of a handle, a stem and a platen for carrying the impression member is adjustable precisely by turning with one's fingers an adjuster that correspondingly turns a stroke limiting stop member and causes it upon turning to be displaced  proportionately  lengthwise  of  the  stem. Several ways of effecting the adjustments are disclosed, including  some  which  eliminate  all  need  for screw-threaded parts by making use of a molded ramp member presenting helical ramp surfaces.  The platen and a case enclosing it are stiffened to resist stamping forces by an array of integral radiating ribs protruding upwardly from  the  platen  and  another  array  of  such  ribs protruding downward from the top of the case: and the ribs of the two sets  intercalate to occupy vertical space in common when the platen is in normal upward position.  A cover closing the case presents structures which  limit  downward  movement  of  the  platen,  and structures connecting the cover with the case resist removal of the cover otherwise than by force applied to an end thereof.   Further, the handle of the device is provided  with  an  asymmetrically  rounded  knob  form enabling reliance on the feel of it in a user's hand for securing right-reading stamped imprints.

Abstract: Known protective helmets used for motorcycle riding, flying and snowmobiling employ transparent visors that have heating elements to reduce and attempt to eliminate the build-up of ice, condensation and fog. A double-lensed face shield is provided with a pair of electrodes formed on an inner face lens, in the air pocket formed between the inner face lens and the outer weather lens. Substantially across one entire surface of the inner face lens is formed an electroconductive film. An upper electrode extends from a first end along an upper margin of the inner face lens on the film to a second end. On the opposite lower margin extends on the film a lower electrode from a first end to a second end. An insulated contact passes from one side of the inner lens to the other and connects the first end of the lower electrode with a conductor which extends on the opposite side of the inner lens towards the first end of the upper electrode. Power supplied across the first end of the upper electrode and the tail end of the conductor will result in electrical flow across the film inhibiting fog, ice and frost.      Also provided is an assembly to permit the installation of face shields on helmets of different sizes and with openings of different configurations.

Abstract: An insulating unit is disclosed having a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. Also disclosed is a spacer for use in insulating units including a plastic core having a gas impervious film e.g. a metal film or a halogenated  polymer film. Also taught herein are techniques for making the unit and spacer. The unit has a long diffusion path to increase the time period in which insulating glass e.g. Argon gas may be retained in the compartment. The increased RES-value provides a unit that has a low thermal conducting edge. In this manner heat loss through the marginal edge of the unit is reduced.

Title: Domestic water treating device including permanent magnet means
Inventor: FREY ERWIN M
IPC: A61L2/18
Filed: 1995-04-06
Granted: 2000-11-14
Abstract: A water  treating  device  for  a  domestic  water handling device such as a toilet water tank,  an air conditioning drain pan or a humidifier includes a housing having permanent magnets in a flow path of water flowing through the housing via openings in the housing,  to collect free ions in the water.  An antimicrobial polymer disinfectant agent is in a mass inserted in a chamber in the housing and/or in a polymer in a housing surface. The housing is configured so an air bubble forms against the housing roof to assure that a base of the housing rests on the floor of the water handling device.  Ribs adding structural strength to the cover are aligned and have approximately the same size and shape as slots in the cover roof through which water passes so the ribs obscure the magnets from view from above and to sides of the cover.  The magnets are held in place by a spring finger extending upward from the base to exert a force downwardly against the magnet upper pole face.

Abstract: A mobile telephone, or personal communication services subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further directory assistance). If a busy signal or non-answering party is detected, a customer is given a plurality of options including leaving a recorded message or page, or a predetermined alphanumeric message or page for the called party. In this case, the system automatically tries, repeatedly, to deliver the recorded message or page and, optionally, confirms successful or failed message delivery to the calling party.

Abstract: L'invention concerne un procédé pour convertir une matte de sulfure de cuivre et/ou un concentré de sulfure de cuivre en cuivre brut. Ce procédé consiste à introduire la matte/ou le concentré ainsi qu'un fondant approprié dans une cuve agitée contenant une phase de scories fondues et une phase de métal fondu, à injecter à l'aide d'une buse submergée un gaz oxydant capable de réagir avec la matte ou le concentré pour former une phase de cuivre brut à faible teneur en soufre, des scories et du dioxyde de soufre, l'injection de gaz se faisant de manière contrôlée pour qu'une proportion substantielle du gaz vienne en contact avec la phase de cuivre brut, et à séparer le cuivre brut des autres composants de la cuve. On peut ainsi atteindre un taux de soufre dans le cuivre brut égal ou inférieur au double de la valeur à l'équilibre pour le pourcentage de cuivre présent dans les scories.
