Title: Automated manufacturing control system
Inventor: CORRIVEAU ANDRE
IPC: G05B19/418
Filed: 2000-11-17
Abstract: An automated manufacturing control system is proposed to greatly reduce the human interaction relative to the data transfer, physical verification and process control associated with the movement of components, tooling and operators in a manufacturing system. This is achieved by the use of data carriers which are attached to the object(s) to be traced. These data carriers can store all the relevant identification, material and production data required by the various elements, e.g. stations, of the manufacturing system. Various readers, integrated with controllers and application software, are located at strategic points of the production area, including production machines and storage areas, to enable automatic data transfer and physical verification that the right material is at the right place at the right time, using the right tooling.

Title: Disc-type coin sorter
Inventor: GEIB JOSEPH J
IPC: G07D3/00
Filed: 1995-08-24
Abstract: A disc-type coin sorter for sorting coin mixtures which include coins of mixed diameters. The sorter has a rotatable disc with a resilient top surface, and a stationary sorting head having a lower surface positioned parallel to the resilient top surface of the disc and spaced slightly therefrom; the lower surface of the sorting head forming a queuing region for aligning the outer edges of coins of all denominations at a common radius. There is a plurality of exit channels for receiving the queued coins, and for guiding coins of different diameters to different exit stations along the periphery of the sorting head. A guide wall extends between at least selected pairs of adjacent exit channels for engaging and guiding the outer edges of coins that do not enter at least the first of the pair of adjacent exit channels; the guide wall maintaining the outer edges of the engaged coins at that common radius. A portion of the lower surface of the sorting head that is traversed by coins between a first and last exit channels tapers upwardly in a radial direction from an area traversed by inner edges of the largest-diameter coins, to a top edge of the guide wall that extends between adjacent exit channels.

Title: Vehicle trailer frame cross member/suspension assembly mount
Inventor: PIERCE PHILLIPPI RANDSOME
IPC: B62D21/02
Filed: 1999-05-14
Abstract: A vehicle trailer frame (130) includes one or more cross member/suspension system mounting assemblies (132a, 132b) which mount axle/suspension systems (150a, 150b) and provide support against the twisting, parallelogram and S-shaped deflections typically caused by vertical, lateral, longitudinal and roll loads commonly encountered by a vehicle trailer during operation, and which can cause premature wear of trailer frame components. Each cross member/suspension system mounting assembly employs a minimal number of parts to support a single axle/suspension system, and includes a cross member (160) and a suspension assembly mounting member (161) disposed at each end of the cross member. Each suspension assembly mounting member is generally triangular-shaped and includes a horizontally-disposed base and a pair of vertically extending, diagonally opposed gussets. A plurality of openings are formed in each suspension assembly mounting member to reduce the overall weight of the cross member/suspension system mounting assembly, to accommodate an air spring mounting bolt, to facilitate welding of the mounting member to the trailer frame, and to promote drainage. Each suspension assembly mounting member fits on the cross member and is attached thereto by a continuous weld, and the mounting member and the cross member both nest in and are attached to other components of the trailer frame by continuous welds.  Suspension assembly hangers are attached to the cross member/suspension system mounting assembly with continuous welds, and other components of a pair of suspension assemblies are suspended from the hangers, which in turn support an axle and wheels.

Title: System and method for using an enhanced external data interface to display data in epl systems
Inventor: GOODWIN JOHN C III
IPC: G06Q20/20
Filed: 2001-04-19
Abstract: A system and method are disclosed for using an enhanced external data interface to display data in EPL systems. The enhanced EDI responds to various stimuli or requests, such as a store manager or other user logged onto a computer terminal in real time, computer-generated applications and timed file data. The enhanced EDI may receive messages to store first information in, or to read first information already stored in, an EPL data file. The EDI determines whether it is time to update a message displayed by a particular EPL or group thereof for a particular merchandise item. If it is time to update the message, the EDI compares information read from the EPL data file with information about the same merchandise item stored in a message management file. If the two pieces of information are different from one another, the EDI causes a message to be transmitted to the EPL, containing the information from the message management file and a command to display such information.

Abstract: Disclosed are methods for reducing the astringency of dentifrice composition containing stannous comprising administering to the subject a dentifrice composition comprising stannous. The dentifrice composition comprises stannous ions, poloxamer, and aqueous carriers. The efficacy of this dentifrice composition containing stannous will not be reduced by the poloxamer. The dentifrice composition may also contain a polyphosphate as long as the water content is limited and the stannous ion is not provided from stannous fluoride. The polyphosphate will also not reduce the efficacy of the stannous.  Alternatively, the dentifrice composition may be a dual phase composition. The first dentifrice composition will contain a polyphosphate having an average chain length of about 4 or more and have a limited water content while the second dentifrice composition will contain stannous ions. In the dual phase compisition, the poloxamer will be present in the first or second dentifrice compositions or both compositions. Neither the polyphosphate or the poloxamer will reduce the efficacy of the stannous.

Abstract: A photo receiver branches a data signal obtained by photoelectric conversion and supplies the signal to a signal cutoff detector. Depending on the degree of an autocorrelation of a data signal obtained by an autocorrelation detector, the signal cutoff detector detects abnormality/normality. Depending on a level of a control signal to a VCO contained in a frequency phase-locked loop for use in clock generation, an out-of-synchronization detector makes determination of abnormality/normality. Outputs of both the detectors are ORed at an alarm processor and when at least one of the detectors detects abnormality, the detector generates an alarm.

Abstract: Quantum mechanic; shows that the spatial localization of the particles is described by probability waves, rather than by well defined values of the coordinates. The inventive idea presented here is a process in which this probability wave is used to transfer the particle between two different space regions. This process is similar to the transfer of electric signals in a properly tuned emitter-receiver system, by using radio waves. I have found that in the case of the probability waves, the emitter-receiver system can be implemented by a suitable, properly tuned three-well potential.
