Abstract: In a method for advancing the beginning of a web (1) of material, in particular a paper web, from below onto the roller (2) of a winding machine, the beginning of the web is moved upwards on a vertical guide plate (11) by means of compressed air. The compressed air is thereby blown upwards along the surface of the guide plate (11) and essentially parallel to the latter in an essentially laminar stream. Serving for carrying out the method is a device having a vertical guide plate (11), extending over part of the operating width, and having at least one flat jet nozzle (12) which has a plurality of upwardly directed blower openings arranged parallel to the guide plate (11), the distance of the blower openings from the guide plate (11) being less than 10 mm, preferably 0.5-1 mm. <IMAGE>

Title: Providing additional system characteristics to a data processing system
Inventor: BAKER ERNEST D
IPC: G06F15/16
Filed: 1990-02-07
Granted: 1996-02-06
Abstract: The functions of two virtual operating systems (e.g., S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system.  One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated from 1 to 16 megabytes of contiguous storage from the S/88 main storage.  Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques.  The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space.  The S/88 Operating System is the master over all system hardware and I/O devices.  The S/88 processors access the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations.  The S/88 and S/370 peer processor pairs execute their respective Operating Systems in a single system environment without significant rewriting of either operating system.  Neither operating system is aware of the other operating system nor the other processor pairs.

Title: Rejection method for speech recognition
Inventor: LENNIG MATTHEW
IPC: G10L15/12
Filed: 1990-03-28
Granted: 1995-09-05
Abstract: A speech recognizer, for recognizing unknown utterances in isolated-word small-vocabulary speech has improved rejection of out of vocabulary utterances.  Both a usual spectral representation including a dynamic component and an equalized representation are used to match unknown utterances to templates for in-vocabulary words.  In a preferred embodiment, the representations are mel-based cepstral with dynamic components being signed vector differences between pairs of primary cepstra.  The equalized representation being the signed difference of each cepstral coefficient less an average value of the coefficients. Factors are generated from the ordered lists of templates to determine the probability of the top choice being a correct acceptance, with different methods being applied when the usual and equalized representations yield a different match. For additional enhancement, the rejection method may use templates corresponding to non-vocabulary utterances or decoys.  If the top choice corresponds to a decoy, the input is rejected.

Title: Analytical assays by noncentrifugal and noncapillary manipulations
Inventor: MESSENGER LOWRY J
IPC: B01L3/00
Filed: 1990-06-05
Granted: 2001-01-02
Abstract: Analytical reaction cassette and method for performing sequential analytical assay procedures to determine the amount of an analyte in a liquid test mixture. The reaction cassette can be in the form of a substantially square container having a substantially horizontal axis of rotation and incorporated with one or more analytical reagents such that they are contacted with a liquid test mixture in a desired ordered sequence to perform a particular assay procedure. corners provided by the substantially square configuration of the reaction cassette disrupt the flow of liquids disposed in the reaction cassette upon contact therewith to thereby agitate and mix such liquids.      A liquid disposed in the reaction cassette is capable of being manipulated and mixed therein by rotating the reaction cassette about the horizontal axis at sufficiently low velocities wherein the transport of such liquid is noncentrifugal and due substantially only to gravitational force. The reaction cassette is particularly useful for performing immunoturbidimetric assays, e.g., for the determination of glycated hemoglobin.

Title: A multilayer angular packing
Inventor: WILHELM GERD
IPC: B01D39/14
Filed: 1990-02-09
Granted: 2000-04-04
Abstract: A regular economically producible packing of use in chemical engineering equipment is described. Physico-chemical phenomena in thermal separating and mixing apparatus in particular are associated with contacts between different phases in cocurrent and countercurrent operation. The important feature of an appropriate packing design is to intensify transverse mixing in the flowing phases and to intensify contact between then. This purpose is served in the packing according to the invention not only by known fan-like vane elements but also by a number of channels rows which are parallel to one another of offset from one another, the effect of such rows being to boost transverse mixing and phase contact of the flowing media, more particularly when the lighter phase flows at elevated speed.

Title: Inductive coupled object identification system and method
Inventor: SLAWINSKI CHRISTOPHER
IPC: G06K7/08
Filed: 1991-01-15
Granted: 2001-12-18
Abstract: An inductive coupled object identification system (FIGURES 2a and 2b) uses inductive coupling to detect and identify objects. Each object includes an object resonance circuit (LT/CT) with a unique object resonance frequency.    Base electronics (50) includes an inductive-coupling base coil (L1) coupled to an oscillator circuit (60). To detect an object, the oscillator circuit continually sends START pulses to the base coil. When an object is proximate to the base coil, a START pules is inductively coupled to the object resonance circuit, causing it to resonate at the object resonance frequency. This resonance condition is detected by the oscillator circuit, which outputs an oscillation signal FREQ at the object resonance frequency.      Frequency counting logic (70) is used to determine the object resonance frequency, allowing a microcomputer (80) to identify the object. Two embodiments of the object identification system are described: a dynamic embodiment (FIGURES la and lb) in which ball-shaped objects (10) are dropped into a bowl (13) through a single base coil (L1) in the rim of the bowl, and a static embodiment (FIGURES 1c and 1d) in which ring-shaped objects (20) are placed over a post (23) incorporating multiple base coils (L1-L5). For the static embodiment, the multiple base coils are multiplexed by a base coil selector circuit (FIGURE 2b, 100).
