Abstract: TIRE LABELING APPARATUS                       Abstract A  tire  labeling  apparatus  (100)  feeds  labels (504) that are releasably adhered to a carrier web (502) from a supply reel  (510)  to a label dispensing station (900) where the labels (504) are transferred one at a time from the web (502) to an application roller (400).  At the dispensing station (900), the carrier web (502) is tightly reversely bent to assist in sequentially "peeling" labels (504)  therefrom;  spent web material  (502)  is withdrawn from the dispensing station (900) and collected on a col-lection reel  (520); and, each newly "peeled" label  (504) is subjected to a jet of pressurized air (800) that forces the indicia-carrying face (506) of the label 504 into en-gagement with a curved, level-receiving portion (430)  of the circumference of the application roller (400).  Holes (426) open through the label-receiving portion (430), and ambient air is drawn through these holes (426) to generate air pressure differential forces that releasably retain each newly dispensed label (504) on the application roller (400) until the roller-carried label (504) is moved to an application station  (1000) where the label  (504)  is ap-plied to a rotating tire bead  (56).  As the application roller (400) is moved between the dispensing station (900) and the  application  station  (1000),  a  resilient roller (470) and a label reader (490) move with it.  At the ap-plication  station  (1000),  the  application  roller  (400) transfers the one label (504) that it carries to a rota-ting bead portion (56) of a tire (52); the resilient rol-ler (470) assures that each newly applied label (504) con-forms to the curved shape of the tire bead portion (50) to which it is applied; and, the label reader (490) reads the label's indicia (506).  Once a valid "read" has been ob-tained, the application roller (400), the resilient roller (470) and the reader (490) are withdrawn, and the applica-tion roller (400) is repositioned at the dispensing sta-tion  (900)  to  receive  a  next-dispensed  label  (504).

Abstract: ABSTRACT OF THE DISCLOSURE      For a torsional vibration damper -- whose working chamber, formed by an inner shell (17), an outer shell (19), a rear wall (15) and a cover (13) is provided to receive a seismic ring and viscous damping liquid (1) -- the housing body (1) bearing the working chamber is manufactured in the metal forming process in a spinning lathe, starting from a round steel blank (7).  In a process that is significantly simplified with respect to the number of clampings and the tool changes, the round steel blank, clamped between mandrel bodies within the spinning lathe, is divided in a splitting process into two blank sections (31, 33), which receive the contour of the cylindrical inner and outer shell (17, 19), defining the working chamber (5) of the torsional vibration damper, owing to the subsequent forming.

Title: Quantum well semiconductor laser device
Inventor: MATSUMOTO NARIHITO
IPC: H01S5/34
Filed: 1991-09-12
Abstract: In a quantum-well type semiconductor laser device comprising a multi-layered quantum-well layer (active layer) constituted by quantum-well layers and a corresponding number of barrier layers and a pair of optical confinement layers respectively arranged on and under the active layer, since the number of quantum-well layers is limited to one or two, the device has a reduced internal loss, a narrowed far-field angle and a bandgap energy of the quantum-well layers greater than that of the optical confinement layers by 160meV ox more so that it shows a lowered threshold current density. Besides, by selecting a thickness of the quantum-well layers between 3 and 8nm, the device can be made to oscillate at the first quantum level in order to make the oscillation wavelength highly dependent on temperature and optical output and accordingly produce a high spectral purity.

Title: Optimization of information bases
Inventor: KAUTZ HENRY A
IPC: G06F17/30
Filed: 1992-06-11
Abstract: A technique for increasing the efficiency of a system such as an artificial intelligence system or a data base system in which a query is applied to a set of formulas. The technique creates an approximation of the set of formulas which iscomputationally more tractable than the original set. The original set is used to answer the query only if the approximation fails to provide the answer. The approximation is made by a compilation process which provides a series of ever-closer approximations. A given query is answered using the currently-closest approximation. The approximation may consist of a first set of formulas which is an upper bound (i.e. implied by) of the original set, and a second set which is a lower bound (i.e. implies) of the original set. In this case, the compilation process produces a series of increasing lower bounds and decreasing upper bounds until agreatest lower bound and a least upper bound are reached. Example applications of the technique are given for propositional languages, first order languages, languages based on definite clauses, and frame languages.

Abstract: Apparatus  is  disclosed  for  maintaining  the temperature of waste water entering a grease trap below a preset temperature.   The apparatus is useful to prevent grease which has collected in the grease trap from being washed into the sewer system by persons attempting to flush the grease from the trap with hot water.   A temperature sensor monitors the temperature of waste water flowing into the grease trap.   Cold water is introduced directly into the waste water conduit, upstream of the trap, through a valve controllably coupled to the temperature sensor whenever the temperature of waste water in the waste water conduit exceeds a threshold temperature.

Title: Method and apparatus for interfacing a station in a token ring network
Inventor: COLLINS JOHN D
IPC: H04L12/42
Filed: 1993-05-17
Abstract: ABSTRACT OF THE DISCLOSURE In a token ring computer network, an adapter is able to interface sta-tions in a variety of configurations. The adapter has two operating modes, one in which an internal relay circuit functions as an integral trunk cou-pling unit, and another in which an external trunk coupling unit is used. The ability to operate in these two modes facilitates interfacing with net-works using star topology, loop topology, or a hybrid of the two. A cable assembly facilitates connection of a network without external trunk cou-pling units using a series of adapters in the "internal trunk coupling unit" operating mode.
