Title: Process and arrangement for testing bottles for the presence of contamination
Inventor: GYSI PETER
IPC: G01N1/26
Filed: 1993-07-07
Abstract: ABSTRACT OF THE DISCLOSURE         To detect contamination in used PET returnable bottles, they are fed to a first testing station which takes a gas sample from each bottle.  This first testing station tests for the presence of heavy contamination.   Heavily contaminated bottles are identified as dirty.  The bottles are then fed to a second testing station  which takes a gas sample  from  the  clean  bottles  and  tests  it  for contamination, with a lower detection threshold.   Bottles detected  here as  contaminated are  removed,  as  are  the bottles which fail the first test.  The two-stage process allows testing with greater sensitivity while maintaining a high bottle throughput.

Title: Article handling system
Inventor: PIPES GEORGE R
IPC: B65G1/133
Filed: 1993-08-16
Abstract: ABSTRACT   An article handling system (10) which essentially consists of a spiral slipsheet (16). To load articles, the slipsheet is rotated and deflected upward so that incoming articles are inserted into the space thus created between the coils of the spiral. As the articles spiral upward on the slipsheet, the upper articles are supported by the articles which have been fed in below them. To unload articles,the entire assembly is rotated 180 degrees and the rotation of the slipsheet reversed to reverse the above process.

Both magnetic tape recorder units and magnetic disc memory units have been known in the art for many years.  Tape units suitable for use in demanding applications are available, but a need exists for an improved disc unit.  Examples of such prior art disk units are disclosed in U.S. Patent Nos. 4,791,508; 4,870,703 and 4,965,686 all of which are assigned to the assignee hereof and are expressly incorporated herein by reference.
Patent CA-2109711-A1 (CA)
Title: Loudspeaker
Inventor: FINCHAM LAWRENCE R
IPC: H04R9/06
Filed: 1992-05-29
Abstract: A loudspeaker construction is disclosed in which a conical diaphragm (15) is caused to generate and radiate sound by means of interaction between a drive coil on a coil former (24) secured to the neck of the diaphragm and a magnet assembly (14) secured to a chassis (10) of the loudspeaker. Electrical energisation of the drive coil produces a drive force acting on the drive coil to move the diaphragm. In order to reduce or prevent radiation of sound from a front ring (11) of the chassis and from a baffle board on which the chassis is mounted arising from reaction to the drive force acting on the magnet assembly, the magnet assembly is mechanically isolated or de-coupled from the chassis. This is accomplished by securing the magnet assembly to the chassis by means of resilient mountings (41) to reduce or prevent transmission of reaction force from the magnet assembly to the chassis.

Title: Hydrogen assisted reduced oxide soldering system
Inventor: TENCH D MORGAN
IPC: H05K3/34
Filed: 1993-12-10
Abstract: ABSTRACT OF THE DISCLOSURE A system is provided for regenerating reducing agents used in ancillary chemical or electrochemical processes such as restoring solderability of electronic components to be soldered in a fluxless soldering process. The system includes a cathode, an anode, and an electrolyte system that is separated by a semipermeable ionic barrier into a catholyte and an anolyte. The catholyte includes the reduced member of a redox couple, which can be regenerated electrochemically. The redox couple of the electrolyte system is charged like a battery and discharged during the ancillary process. Regeneration of the reduced member of the redox couple is accomplished at the cathode, which may evolve hydrogen gas. Chemical balance is maintained by the semipermeable ionic barrier, which permits proton migration from the anolyte to the catholyte but acts as a barrier against diffusion and migration of cations from the catholyte to the anolyte. Ideally, the anodic reaction is breakdown of water to form oxygen, which is vented, and protons that migrate across the ionic barrier to the catholyte replacing protons consumed in the ancillary process. The overall reaction in a fluxless soldering system is reduction of metallic oxides to metal, electrochemical regeneration of reducing agents, release of oxygen, and evolution of hydrogen to produce a reducing atmosphere in an enclosed chamber containing the fluxless soldering system.

Inventor: WOLLIN ERNEST
IPC: A61B5/055
Filed: 1994-05-30
Abstract: A magnetic resonance imaging apparatus includes a magnet system for producing a homogeneous magnetic field along the z axis. A plurality of wire conductors are arranged in a "bird cage" or "squirrel cage" configuration and are supplied with a circularly rotating RF field centered near the Larmor frequency .omega.o. The wire conductors also receive a voltage source V p having a frequency .omega.p, which is less than the Larmor frequency. The voltage source V p is rotated about the wire conductors at a frequency of .omega.~, which is much less than the frequency .omega.p, to successively apply the voltage V p to each pair of diametrically opposed wire conductors in a manner which is ordered as a spatial cylindrical harmonic rotating at a frequency w~. The voltage source V p produces electric fields in the object which, in turn, generate linear magnetic field gradients in the object. The voltage source V p phase encodes the signals detected from the object which thereby enables a transverse magnetization at each point within the object to be rapidly mapped back. With the invention, an image of the object is rapidly and continuously produced without requiring the use of the conventional gradient field coils and without any mechanical moving parts.
