Granted: 1998-06-16
Abstract: A pressure controlled actuator mechanism (10) is disclosed for imparting rotary control motion to devices, such as valves, having rotary control means. The actuator includes a free-floating piston (20) movably and concentrically disposed within an airtight cylindrical housing (16). A non-rotating receptacle (36), having helically spiralled recesses therein, is attached therein to a support member (30) that is adapted to move in response to the free-floating piston (20). A rotatable shaft (42), one end of which mates with the helically spiralled recesses of the receptacle, is attached at its other end to a device having a rotary control means. A downward stroke of the receptacle rotates the shaft and activates the device. The support member (30) is spring biased to return the free-floating piston (20) to a starting position. In an alternative embodiment, the free-floating piston (20) is movably and concentrically attached to the support member (30) for travel therewith.  In this embodiment, a second pressure medium is introduced into the housing to cause the piston and support member to return to a starting position.

Title: A chemiluminescent method for the quantitation of human dna
Inventor: REYNOLDS REBECCA L
IPC: G01N33/53
Filed: 1993-08-24
Granted: 2009-06-23
Abstract: The present invention provides methods and reagents for the estimation of the quantity of human DNA contained in a sample. Immobilized sample DNA is hybridized to a biotinylated oligonucleotide probe that hybridizes to a human genomic or mitochondria DNA sequence. The subsequent binding of streptavidin-horseradish peroxidase to the bound probe allows for chemiluminescent detection using a luminol-based reagent and X-ray film. In addition, the present invention provides methods and reagents to assess the quality of DNA contained in a sample. The sample is first size fractionated by agarose gel electrophoresis, and then immobilized, hybridized to a biotinylated oligonucleotide probe, and detected using the chemiluminescent method as used in the quantity estimation methods of the present invention.

Abstract: A method for performing cardiopulmonary resuscitation employs an applicator device having a body with an upper surface and a lower surface. The lower surface includes provisions for detachably securing to the patient's chest, such as a vacuum cup or an adhesive layer.  For manual resuscitation, the upper surface will include a strap or other means for securing a performer's hand thereto.  In an exemplary device, a disc-shaped handle is attached to the upper surface of a vacuum cup applicator by a short connecting stem structure.  For automatic applications, a mechanical drive member will be secured to the upper surface.  By alternately pressing and lifting on the applicator device, the patient's chest can be compressed and expanded to improve induced ventilation and circulation.

Abstract: An apparatus which advances sheets from different stacks of sheets. In one mode of operation, two stacks of sheets are supported side by side. A sheet feeder associated with each stack of sheets advances successive uppermost sheets from the respective stack to a transfer station of a printing machine. Alternatively, a single sheet feeder mounted movably in the sheet feeding apparatus may be employed to advance successive sheets from each of the stack of sheets, in lieu two sheet feeders. In the absence of these stacks of sheets, another oversized stack of sheets may be positioned in the sheet feeder. This oversized stack of sheets extends from a first sheet storing section into a second sheet storing section. When two stacks of sheets are disposed in the sheet feeder, one stack is positioned in the first sheet storing section and the other stack is positioned in the second sheet storing section. In this way, the sheet feeding apparatus has capability of feeding multiple size sheets.

Patent CA-2161723-C (CA)
Inventor: BERTOCCI GUIDO
IPC: H04M1/72508
Filed: 1995-10-30
Granted: 1999-09-14
Abstract: A cordless telephone system achieves synchronism for each one of multiple portable units to the same communication  channel for communicating with a common base unit. The cordless system uses a dual channel process to allow both the freedom to dynamically change channels as needed to avoid interference whilesimultaneously providing a capability to resynchronize any portable unit with the base unit on a selected active channel. This is achieved through the use of a fixed service channel and an active channel which changes as needed. If a channel change is made during a call, after the call is completed, the base unit returns to the previous active channel and broadcasts a message to the multiple portable units indicative of the new active channel. Also, any portable unit that attempts to communicate with the base unit on the wrong channel and fails to get a response will transmit a message on the fixed service channel requesting the current active channel from the base unit. Responsive to this request, the base unit provides information indicative of the active channel over the service channel. Once equipped with the current active channel information, the portable unit is able to reach and establish communications with the base unit.
Patent CA-2163604-C (CA)
Title: Electronic device housing having storage portion
Inventor: DEGUCHI MANABU
IPC: H04B1/38
Filed: 1995-11-23
Granted: 1999-11-02
Abstract: An electronic device housing comprises a cover with a locking groove, an operation portion with a locking portion corresponding to the locking groove, and a housing to which the cover is attached. The cover is slidably mounted on the housing. Both the locking groove of the cover and the locking portion have portions inclined with respect to the cover, for instance, a portion shaped as a parallelogram in cross-section. The operation portion has a portion that slides in a direction perpendicular to the sliding direction of the cover. With this sliding portion, the locking portion is slidably inserted into and withdrawn from the locking groove. When the locking portion is fitted into the locking groove so that the cover is mounted on the housing, the cover cannot be dropped from the housing. The operation portion is attached to a portion of the housing, and is moved downwardly by depressing the housing from the upper direction. When the cover is mounted on the housing and the operation portion is depressed downwardly, the locking portion fitted to the locking groove of the cover also moves downward. A wedge effect is produced by the force exerted between the locking portion and an inclined edge located opposite to the locking groove.  The cover then slides along the removing direction in response to force produced by this wedge effect. As a consequence, the cover may be removed, by simply taking it out from the housing without sliding the locking piece. Since the cover moves downward when the operation portion is depressed, the pawl of the engaging piece for preventing the cover from being dropped is automatically released from the housing and removed.

Title: Subtitle colorwiping and positioning method and apparatus
Inventor: TSUKAGOSHI IKUO
IPC: H04N19/89
Filed: 1996-04-01
Granted: 2004-06-22
Abstract: Colorwiping and dynamic positioning of subtitles is achieved by encoding and decoding the subtitles separately from the video image. At the encoder, subtitles are generated for each respective video image. Colorwiping is performed by changing the color of the subtitles at a certain location in the video image. At the decoder, a buffer stores the subtitles along with subtitle decoding information. A controller precisely times a reading operation of the buffer to read out the subtitles during a real time display of the respective video image; and colorwiping is performed by changing the color of a portion of the subtitles at a location indicated by the subtitle decoding information. Dynamic positioning of the subtitles is achieved by delaying the time the controller executes the read operation. When the decoding technique is repeated for a number of frames, the viewer senses motion as the colorwiping and positioning gradually changes.
