Abstract: A device for dispensing tickets from a continuous strip of paper (1), each ticket being constituted by an end segment of the strip suitable for being grasped by a recipient of the ticket and detached by applying traction to said end, the device comprising a mechanism for pinching the paper along a line (3) extending transversely across the strip (1), and downstream from this mechanism, a cutting blade (4) extending substantially transversely across the strip, with the strip bearing against the cutting edge (5) of the blade when the above-mentioned traction is applied, wherein the cutting edge (5) of the blade is formed by a straight-line segment that intersects the plane of the strip of paper (1) in contact with the blade (4) prior to cutting and containing the pinch line (3), with the projection (7) of the blade onto said plane converging towards the pinch line (3) from the point (6) where the paper first comes into contact with the blade (4).

Abstract: The invention relates to a printer device for printing on a paper tape and for cutting the tape into printed tickets. The device comprises a frame having a cover hinged on the frame, a printer, cutter means, and guide means for guiding the tape between the printer and the cutter means. According to the invention, the guide means are formed by two walls substantially parallel to the axis of a paper drive roller, one wall being carried by the cover and the other wall being carried by the frame, in such a manner as to impose an S-bend on the portion of the tape that extends between the printer and the cutter means.

Abstract: The apparatus of the present invention generally comprises a wastewater contact tank that is broken into three distinct zones: a selector zone positioned between a stabilization zone and a contact zone. The entire influent is introduced into the selector zone which is maintained in an anoxic condition. Baffles positioned within the selector zone permit control of microorganisms levels present in the zone. The wastewater introduced into the selector zone and treated via the microorganisms present therein, flows over a weir into the contact zone. In the contact zone, the solids suspended in the liquor (the mixture of the wastewater and activated sludge) settle to the bottom and pass through a line which returns it to the selector zone. The return line, however, includes a valve which controls the rate of passage. The treated wastewater (which includes waste activated sludge and treated water) passes from the contact zone into the clarifiers for final processing.

Abstract: Apparatus for supporting a coaxial cable, or the like, and effecting cutting and stripping operations to remove a portion of one or more layers which concentrically cover a central conductor. A single blade, having a circular cutting edge, is moved in an orbital path about the cable with rotary motion of a motor translated to orbital motion of the blade through a plurality of plates relatively movable on crossed, linear, roller bearings and a shaft eccentrically affixed to the motor with the shaft and motor axes at an acute angle to one another. The shaft extends through a spherical bearing mounted in one of the plates, thereby translating nutational motion of the shaft to orbiting motion of the plate which is directly attached to the blade. A unique clamping assembly includes a pair of jaws having respective gear racks engaging a single pinion gear on a motor output shaft for linear movement of the jaws by equal distances in opposite directions.

Abstract: A device for use by an authorized person having an unique biometric parameter to obtain information for use in accessing a secured site. The device comprises a biometric interface unit engaged with a portable body member. The device further comprises biometric circuitry adapted to generate and store an initialized biometric template upon presentment of the person's unique biometric parameter to the biometric interface unit. The biometric circuitry is further adapted to generate a second biometric template upon subsequent presentment of the person's unique biometric parameter to the biometric interface unit. The device further comprises compare circuitry adapted to generate an first signal indicative that the second biometric template is substantially identical to the initialized biometric template. The device further comprises a storage device for storing a plurality of passwords.

Abstract: A system 100 is disclosed for monitoring the position of one or more RFID tags 201. The system has a detector 301 incorporating circuitry 304 for detecting changes in the range of an RFID tag 201 from the detector and for triggering an alarm 401 if a detected change in range of an RFID tag 201 exceeds a predetermined threshold or if the RFID radio tag cannot be detected by the detector 301. Range may be detected, for example, by measuring the time of a returned radio signal from a tag 201, by measuring the strength of a returned radio signal from a tag, or by detecting changes in a periodic interval at which energy is transmitted by a tag.

Abstract: The invention involves a device and method for ascertaining the functioning of the respiratory system and determining whether a pulmonary embolism is present. The device comprises an apparatus containing sensors for measuring the oxygen and carbon dioxide concentrations as well as the volume of air inhaled and exhaled by a patient. From this data, a processor computes the ratio of carbon dioxide to oxygen for the volume of expired air and displays the results on a screen. By comparing the results to predetermined normal values, an accurate determination can be made regarding the presence of a pulmonary embolism.

Abstract: The present invention provides an air handling system that receives air from a primary air source and distributes that air in a room defining an enclosed space. The system is mounted in the ceiling of the room and generally comprises first, second, third, and fourth inductor units interconnected downstream to the primary air supply and which define first, second, third, and fourth areas, respectively, wherein the induced air flows through each of the inductor units, through a series of converging nozzles, and into each units first, second, third, and fourth areas, respectively, and an air diffusing mechanism positioned adjacent to the first, second, third, and fourth areas which directs the induced air in first, second, third, and fourth directions, respectively. The inductors are generally arranged in a square configuration with the diffuser extending in the square space bound thereby.

Abstract: The present invention provides a two stage process for treating wastewater that subjects the influent to anoxic and oxic filtering processes. The first stage performs anoxic nitrification i.e., the conversion of nitrate to nitrogen gas by bacteria operating in the absence of oxygen. Influent (effluent from the primary clarifiers) is fed into the bottom of the anoxic dentirification tank, preventing contact with the atmosphere and thus reducing the amount of unwanted dissolved oxygen. The influent passes upwards through a layer of sludge biomass before contacting bacteria coated media which performs the denitrification process. This arrangement permits the influent to contact the sludge and the biomass to circulate through the filter, enhancing deoxygenation and the performance of the system.
