Abstract: ABSTRACT An ink-transfer thermal serial dot printer has a mechanism switch-ing from a head-down state of the thermal head to a head-up state.  The printer has a winding up mechanism for a take-up reel for an ink-transfer ribbon, the operation of which is performed or not performed in connection with the switching of the head-down or head-up state of the thermal head, causing the feeding of the ink-transfer ribbon during the spacing operation (in head-up state) of the printer to stop to save the ink-transfer ribbon.  The switching mechanism involves a cam and cam follower giving rise to a virtually noiseless cam action.  Also the inertia of the moving portion associated with the switching operation is minimized to increase the switching speed.

Abstract: IMPROVED METHOD AND APPARATUS FOR WRAPPING MACHINE                Abstract of the Disclosure A package is conveyed to a package elevator which elevates it into a film sheet stretched above the elevator.  side folding levers and a coordinated rear folder fold three sides of the film sheet about the package such that edges of first and second opposed sides of the film sheet are overlapped by edges of a third or rear side of the film sheet.  The infolding of the third side of the film sheet by the side under-folders is delayed at the rear edge of the package by expanding the opening between the side underfolders in that area.  Thus, the rear underfolding of the third side commences substantially at the rear corners of the package to expand the underfolded third side and ensure film overlap.  The package is then pushed onto a conveyor to underfold the fourth side of the film and  entirely cover  the  underside of  the package by overlapping  edges  of  the  folded  sides  of  the  film sheet.  The infolding is delayed by an improved side folding lever having a curvilinear folding edge with a notch formed at its inner end in substantial alignment with  the  rear  edge  of  the  largest  packages  to  be wrapped  using  the  folding  lever.   Preferably,  the notches  comprise  curvilinear  trailing  edges  which serve to tuck and roll the edges or infolded portions of the third or rear side of the film sheet as it is rear underfolded.

Abstract: Abstract:         In accordance with the present invention a person is identified, or asserted identity is verified, from speech patterns by analyzing his or her prompted utterance to generate a set of acoustic feature signals and comparing the utterance feature signals to reference acoustic feature signals characteristic of previously identified speakers without time sequence information preserved.  In the identity determination, the best matching of the word-organized reference feature signals characteristic of the identified speaker is found for each successive utterance feature signal and a signal representative of the similarity of the best matching reference feature and the current utterance feature signal.  The correspondence of the utterance and the reference acoustic feature signals of the identified speaker is evaluated from the sequence of similarity signals.  The reference acoustic feature signals are vector-quantized and placed into a codebook according to respective indices for each word or phrase; and the prompted utterance is arbitrarily selected from among those words or phrases for which indices exist.

Abstract: ABSTRACT OF THE DISCLOSURE Continuous status monitoring of a plurality of switches and smart sensors associated with the switches, wherein each sensor is connected to a separate single point on a single-wire bus is affected by a smart sensor multiplex arrangement. The multiplex arrangement employs a microcomputer and a driver and receiver circuit for developing a particular pulse train waveform, which is placed on the bus to provide power and control voltage signals to the plurality of smart sensors. Thesmart sensors contain circuits that respond to the waveform in a manner that causes each smart sensor to send current signals back over the single wire bus to the driver and receiver circuit and the microcomputer during designated repetitive and sequential time slots. The driver and receiver circuit receives, interprets and converts the current signals into voltage signals used by the microcomputer for establishing a history of the status of the bus, the sensors and the switches. The microcomputer supplies continuous and updated information to a display system indicative of the status of each sensor and its associated switch.

Abstract: ABSTRACT            IMPROVED METHOD FOR ADHESION OF GRIT TO BLADE TIPS     Metal coated ceramic particles are bonded to a metallic substrate in a high temperature sintering process.  A low viscosity binder solution containing fine metallic particulates is first applied to the substrate surface.  Then, the coated ceramic particles are disposed upon the substrate surface, and the binder solution and the metal particulates therein are attracted by capillarity into regions of point contact between the ceramic particles and the substrate surface.  During a subsequent high temperature sintering operation, the metal coating on the ceramic particles diffuses into the metal substrate, and the metallic particulate melt and solidify to bridge the gap between the substrate and ceramic particles.
