Title: Gate valve sleeve
Inventor: MCKAVANAGH THOMAS P
IPC: F16K3/02
Filed: 1992-09-11
Granted: 1998-08-18
Abstract: A sealing sleeve for a gate valve is disclosed which is designed to respond to movements of the gate of the valve in a particular manner.  The seal undergoes an axial compressive type movement as the gate is moved between opposed sealing sleeves and this causes a predetermined radially inward buckling of an intermediate wall section of the sealing sleeve.  This predetermined buckling creates a spring bias in the sleeve, urging the sleeve to return to the original, less stressed condition. Preferably, the sleeve is of a composite structure and a particular component of the intermediate wall section creates this spring bias.  This structure has improved operating characteristics and accommodates a wider range of resilient materials to be used for the sealing sleeve.

Abstract: An interferometric tunable optical filter selects a predetermined wavelength or wavelengths from a wavelength division multiplexed signal. The optical filter splits an input signal into a plurality of waveguide branches. In each branch, the amplitude and phase of the signal can be individually controlled. The signals are then recombined. The resulting interference gives a wavelength dependent transmission spectrum that can be adjusted as desired.

Abstract: A handheld vacuum cleaner is provided that has a motor mounted with the rotational axis of its shaft parallel to the rotational axis of the rotating brush.  The vacuum cleaner motor has an end bell, which is attached to the motor stator, and which holds a motor shaft bearing.  The end bell is secured to the vacuum housing with an elastomeric mounting ring to dampen motor vibrations.  The need for most motor mounting hardware is eliminated, because the housing supports the motor stator directly.  The intake orifice of the vacuum is shaped to lie in two distinct planes, so that flat cleaning surfaces do not obstruct the orifice.  The shape of the intake also allows one to clean immediately adjacent to a vertical wall.

Abstract: A multi-element surgical drape includes a bottom sheet that is placed over a patient and a top sheet that is reversibly secured to the bottom sheet. The two sheets each have a fenestration, and the fenestrations are aligned to provide access to the surgical site. After the surgical procedure has been completed the two sheets are separated. The top sheet is contaminated ("red-bag") medical waste, while the bottom sheet can be disposed of as non-contaminated waste, recycled, or processed for reuse. A pouch is provided on the top surface of the top sheet near its fenestration for collecting fluid run-off during surgery. This pouch has a top edge and a bottom edge joined by two opposing side edges, with the side edges and bottom edges being sealed. The sealed top edge is detachable to permit opening of the pouch to receive fluid and then closing of the pouch to prevent leakage of the fluid. The invention permits a substantial reduction in the volume of red-bag waste generated by surgery.

Title: Electrostatographic single-pass multiple station printer with register control
Inventor: AERENS RONNY JEAN VALENTINE
IPC: G03G13/00
Filed: 1994-06-15
Granted: 2000-10-17
Abstract: An electrostatographic single-pass multiple station multi-colour printer for forming an image onto a web is described.      The printer comprises a plurality of toner image-printing electrostatographic stations (A,B,C,D). Each station has a drum onto the surface (26) of which a toner image can be formed. An exposure station (30) forms an electrostatic toner image line-wise on each drum surface. A corona device (34) transfers the toner image onto the web (12), which is conveyed in succession past said stations (A,B,C,D) in synchronism with the rotation of the drum surface (26). Register control means are provided for controlling the operation of each of said stations in timed relationship thereby to obtain correct registering of the distinct toner images on the web (12). The register control means comprises an encoder (60) driven by the displacement of the web to produce pulses indicative of web displacement, and delay means (71) arranged to initiate the operation of subsequent stations after a predetermined web displacement, as measured by the encoder means, has occurred.      The invention enables accurate registration of the transferred images, irrespective of the speed of the paper web through the printer.

Granted: 1997-12-09
Abstract: A raster output scanning system is disclosed which utilizes two light beams to double scan two scan lines on a photoreceptor in order to generate three exposure levels required for a tri-level printing system. In the raster output scanner of this invention, the two light beams scan two separate scan lines. At the completion of the simultaneous scanning of two light beams when the first light beam starts to scan a new scan line, the second light beam start to scan the scan line that the first light beam just completed scanning. In this invention the first light beam generates two exposure levels and the second light beam adds additional exposure to the second exposure level in order to generate a third exposure level. The same method can be utilized to generate additional levels for printing systems with more xerographic levels than three.

Abstract: Filtre (10) comportant une cartouche filtrante (12) contenant un matériau filtrant (20) plissé en zigzag. Des bandes stabilisatrices (34) sont collées le long des deux parois longitudinales (36) de la cartouche (12) afin de stabiliser la configuration en zigzag du matériau filtrant (20). Pendant l'utilisation du filtre (10), la cartouche filtrante (12) est insérée à l'intérieur d'un cadre porteur (14), lequel est disposé à l'intérieur d'un logement aménagé dans la conduite d'admission d'air (18) d'un système de conditionnement d'air. En raison de la stabilité inhérente à la configuration du matériau filtrant (20) et des bandes stabilisatrices (34), la cartouche filtrante (12) est suffisamment rigide pour être autoporteuse. La cartouche filtrante (12) est de manipulation facile et peut être facilement insérée dans son cadre porteur (14). Hormis le matériau filtrant lui-même (20), la cartouche filtrante ne requiert que peu de remplacement de matériel autre que les bandes stabilisatrices (34). La quantité de matériel autre que le matériau filtrant lui-même (20) qui doit être mis au rebut lors du remplacement de la cartouche filtrante (12) est donc extrêmement minime.

Title: Soft decision signal outputting receiver
Inventor: USHIROKAWA AKIHISA
IPC: H04L1/00
Filed: 1995-06-21
Granted: 2000-08-29
Abstract: A receive condition in burst transmission varies in units of a burst or a plurality of symbol times.      The present invention provides a soft decision signal outputting receiver which can simply produce correct reliability information even if the receive condition varies while employing a simple reliability information production method. A demodulator demodulates a burst signal to obtain a hard decision signal. A time-varying reliability information production circuit receives information of a demodulation process from the demodulator 11 and produces reliability information regarding the hard decision signal. The time-varying reliability information production circuit receives signal quality information which reflects a receive condition for each burst or each plurality of symbol times, and changes, based on the signal quality information, a production method for reliability information or elements such as threshold levels to be used in a production method for each burst or each plurality of symbol times. A soft decision signal production circuit produces a soft decision signal from the hard decision signal and the reliability information.

Granted: 2000-01-25
Abstract: A pipe coupling device for holding a metal pipe having a selected diameter within a range of a nominal diameter plus or minus a specified tolerance is also useful for easily determining if any pipe is within specifications. A split metal ring having a diameter equal to the nominal diameter for the metal pipe and a transverse split having a width equal to the specified tolerance is placed around the pipe. A flange having a tapered cylindrical bore having diameter such that the diameter plus twice the thickness of the split metal ring equals the nominal diameter of the metal pipe plus the specified tolerance is fitted over the split metal ring. If the pipe is undersized it will slip through the split metal ring. If the pipe is oversized the flange will not fit completely over the metal ring surrounding the pipe.
