Title: Modular wall panel interconnection apparatus and method
Inventor: LOSENSKY CHARLES I
IPC: E04B2/74
Filed: 1991-03-28
Granted: 1995-02-28
Abstract: A space divider system for subdividing an interior space into distinct work areas is disclosed.  The space divider system makes use of modular wall panels having improved interconnection components adapted to interact with tubular mounting frames which are interconnected intermediate to adjacent wall panels.  Each wall panel includes a spring-biased upper bracket and a lower bracket each of which is mounted to a respective upper and lower horizontal surface at each corner of the wall panel.  The lower bracket has an upturned lip which captures the lower open end of the mounting frame.  The upper bracket is normally biased in an open position to permit the mounting frame to be aligned against the wall panel and is thereafter moved downward until  its downturned lip captures the open upper end of the mounting frame.          Pre-assembly of the upper bracket on each wall panel permits a method of easy and quick assembly and disassembly of the wall panels.

Title: On-line micro formation sensor
Inventor: JORDAN BYRON DALE
IPC: G01N21/59
Filed: 1990-05-28
Granted: 1995-12-26
Abstract: An optical scanner includes a light source (39) which directs a beam of light at a web of moving paper whereby the beam of light is transmitted through the web of moving paper. The transmitted beam (43) is split by a beam splitter (19) to provide a first split beam (44) travell-ing in a machine direction and a second split beam (45) travelling in a cross-machine direction. The split beams are received by charge-coupled device linear arrays (15, 19) which provide analog signals having magnitudes  pro-portional to the magnitude of light intensity of the split beams. The analog signals are fed to analog-to-digital converters which provide digital data at the output. The digital data is then used to compute paper formation de-scriptors including paper mass variation, floc size statis-tics and histogram, Fourier power spectra and paper anis-otropy.

Abstract: The invention relates to a holder for a cradle of a coating bar or for a coating blade in a coating unit and a method for securing the cradle of the coating bar or the coating blade in a coating device. The coating bar or blade are arranged to spread and smooth a size film or a corresponding layer of coating agent onto a face of a moving base to be coated by loading the coating bar or blade against the moving base. The moving base may be a roll of a size press or the web passed over a back-up roll. The cradle of the coating bar or the coating blade is mounted in a holder arranged in an application beam transverse to the machine direction. A journalling duct transverse to the machine direction is formed in the frame of the holder. An oblong member is arranged rotatably in the journalling duct and comprises a cam-lake projection of eccentric section. The member can be rotated for the purpose of fixing the cradle of the coating bar or the coating blade in its place. In this position, the cam-like projection rests against a rear face of the cradle of the coating bar or of the coating blade and secures the cradle or coating blade against a support provided on the application beam.

Granted: 1999-01-26
Abstract: A package  assembly  for  a  medical  device  comprises  a container  for  the medical device,  a generally cylindrical hollow tube with distal and proximal ends and a sidewall. The  external  side  of  the  container  has  an  outwardly extending rim at its proximal end.  The packaging assembly further includes a generally cylindrical hollow tube with an open bore.  The bore has a proximal portion and an adjacent distal portion at an interface.  The tube has a rim with a generally planar surface extending outwardly at the proximal end.  The container is sized so that its distal end fits in to the open bore of the tube. The tube proximal portion is sized to accept the rim of the container.  The tube distal portion is sized so that the container is allowed passage up to its rim.   The inner surface of the proximal portion of the tube has an inward projection which allows the rim of the container to pass over it when the container is moved distally, but is shaped to resist passage of the rim with proximal movement of the container.  The design of the tube makes  it  unlikely  that  the  tube can  be  unintentionally removed from the shield, thus providing a secondary barrier to needle sticks if the needle should penetrate the needle. The tube  flange  is preferably provided with a barrier to passage of microorganisms.

Granted: 2004-04-20
Abstract: A bottomless vial (2) for forming a syringe has a strengthening bead (6) at its wider open end to which a combination finger grip and piston retainer can be secured. The bead is formed at least partly inward of the main portion of the inner surface of the sidewall (4) of the body, so as to reduce or eliminate projection of the bead beyond the main portion of the outer surface of the sidewall (4). By forming the bead by flaring of a reduced diameter end portion (74) of the body, this objective can be achieved whilst providing a flare (76) which assists insertion of the piston and a shoulder (84) to retain the finger grip and piston retainer (16).

Abstract: A data demodulator circuit for spread spectrum communi-cation, presenting improved demodulation characteristics by allowing the elimination of the influence of a carrier offset remaining after down converting, and the removal of the interference caused by pilot signals with different timing.          In-phase axis received signal and quadrature axis received signal are provided to data demodulator circuits adapted to operate with their respective reception timing of pilot signal.  A phase difference information extracting means extracts phase difference information from the input signals, and delay means delays the received signals so as to ensure that extracted phase difference information is equivalent to the amount of average phase revolution.  A frequency and phase compensation means eliminates the influence of the carrier offset by use of thus extracted phase difference information.  A data demodulation means with canceler removes an interference IDF of pilot signals with different timing originating from the outputs of an interference amount calcu-lating means.
