Title: System and method for providing power over a home phone line network
Inventor: RABENKO THEODORE F
IPC: H04M19/08
Filed: 2001-04-24
Abstract: A system and method is provided for supplying power over a home phone line network in a manner that is interoperable with other voice and data services operating on the same network. The system includes a power source coupled to the home phone line network. The power source includes an AC signal generator that generates an AC signal at a selected frequency. The power source also includes a band pass filter for removing unwanted harmonics from the AC signal, thereby generating a filtered AC signal for powering one or more devices on the home phone line network. One or more devices attached to the home phone line network, such as a telephone adapter or telephone, receives the filtered AC signal. Each device comprises a second band pass filter and an AC/DC converter. The second band pass filter passes the filtered AC signal to the AC/DC converter and prevents the introduction of undesired harmonics onto the home phone line network from the AC/DC converter. The AC/DC converter converts the filtered AC signal to a DC signal used for powering the device.

Title: Continuously-excited laser
Inventor: MCLEARY ROSS C
IPC: H01S3/03
Filed: 1981-12-02
Abstract: Continuously - excited lasers of the CO<u2>u mixing, and supersonic CO, types. There is specifically disclosed a method, and a laser apparatus, for producing a repetitively pulsed output, in which a stream of excited gas, of the type having a relatively long excitation life, is produced, stored and subsequently transferred, in the form of pulses, to a power extraction zone incorporating a resonator. In one example the gas laser is a supersonic CO laser in which the CO is excited in the excitation zone and is, after storage, transferred under supersonic conditions to the resonator. In the main example the gas to be excited is N<u2>u which is initially transferred to a storage chamber provided between a rotatable storage cylinder (16) and an axial supporting shaft (18) therefore, and thereafter the N<u2>u is transferred through holes (17) in the storage cylinder (16) which align during rotation with slots (20) through a surrounding fixed cylinder (19) to allow pulses of excited gas to be transferred to the power extraction zone (12) where it is mixed with CO<u2>u and He, entering through supply tubes (23), and to which it transfers its excitation before flowing to the resonator.

Abstract: Packaging for foodstuffs, particularly meat, comprises a rigid tray (3) of plastic material, preferably polypropylene, enclosed between two opposing, preferably transparent, plastic webs (2, 4), one of which (4) has a depression formed therein in which the tray nests. The tray has corrugations (5) which give it its rigidity, with those on the base (7) also serving to support and space the contents above the base. The package is air evacuated and filled with a desired gas to prevent deterioration of the contents. The method of packaging essentially entails placing the tray, with contents, in the depression, overlying the upper web, evacuating and gasifying the partially completed package and sealing the webs together. Apparatus for performing the method is also disclosed.

Abstract: L'invention concerne une bande de suture adhésive servant à fermer la plaie d'un patient et comprenant un élément dorsal allongé, souple et perméable au rayonnement, des extrémités opposées, une première et une seconde surface opposées l'une à l'autre, ainsi qu'une longueur et une largeur suffisantes pour assujettir les bords opposés de la plaie en contact étroit l'un contre l'autre. L'élément dorsal comporte une première partie, située entre les extrémités et conçue pour recouvrir les bords opposés de la plaie, une deuxième et une troisième partie, disposées sur l'une et l'autre des faces de la première partie. Un adhésif autocollant et un adhésif durcissable au rayonnement recouvrent au moins partiellement la première surface de l'élément dorsal, cette surface comprenant les deuxième et troisième parties dudit élément. L'adhésif autocollant sert à faire adhérer au moins les deuxième et troisième parties de l'élément dorsal sur la peau du patient, les bords opposés de la plaie étant en contact étroit l'un contre l'autre. L'adhésif durcissable au rayonnement sert à renforcer l'adhérence des deuxième et troisième parties de l'élément dorsal sur la peau du patient. Selon l'invention, la bande de suture comporte également un élément de protection fixé de manière amovible à l'élément dorsal et recouvrant l'adhésif autocollant et l'adhésif durcissable au rayonnement. L'élément de protection étant enlevé pour découvrir ces deux derniers adhésifs, l'élément dorsal est appliqué avec l'adhésif autocollant contre la plaie du patient pour assujettir les bords opposés de la plaie l'un contre l'autre, et l'élément dorsal est irradié par des rayons provoquant le durcissement. Sous l'effet du durcissement, l'adhésif durcissable au rayonnement maintient, avec l'élément dorsal, les bords opposés de la plaie en contact étroit l'un contre l'autre.

Abstract: A slurry distributor (S) for distributing a low viscosity fluid into a viscous, hydraulic slurry comprises a main conduit (1) located on a first axis a for conducting a flowing, viscous, hydraulic slurry towards an orifice (3). The distributor (S) has an air injector (5) defined by a stem (7) located on a second axis .beta..      The air injector (5) is for introducing air into the slurry to disperse it from the orifice (3). A second injector (9) located on a third axis .gamma. and intersecting the main conduit (1) is used to introduce a low viscosity liquid, preferably an accelerator, into the flowing slurry such that the low viscosity liquid impinges on the air injector stem (7) before dispersion. The distributor is especially useful with fireproofing compositions since it provides effective distribution of a viscous, hydraulic, cementitious slurry with an acidic accelerator.

Title: Proximity sensor and method of making
Inventor: SCHUTTS MARK E
IPC: G01B7/00
Filed: 1990-01-24
Abstract: Abstract of the Disclosure A proximity sensor has a metal case with a sensing coil at one end and a coaxial cable extending out the other end  for placement  in proximity to rotating machinery to sense imbalances by position change of, for example, a shaft.  The sensor includes a cylinder integrally molded with a plastic bobbin which carries the coil on its end.  This unitary assembly then has inserted in it the coaxial cable and the typically wire braided outer conductor is soldered onto the cylinder to provide a permanent interlock resistance against  axial  and  torsional  forces.    A  plastic insulating cap is placed over the entire assembly including the sensing coil and epoxied thereto.   A sleeve  over  the  junction  between  the  cable  and cylinder prevents unwanted epoxy from filling the coaxial cable.   Finally, this permanent affixing of the cap allows the metal casing normally having a nut and thread to be crimped onto a notch in the cap. Moisture proofing is also provided by injection of silicone rubber in the cavity of the bobbin.
