Title: Apparatus and method for reproducing data from multi-layered disk
Inventor: NISHIKATA MASANOBU
IPC: G11B7/09
Filed: 1995-12-11
Abstract: To move an object lens out of focalization on a layer and to accelerate it upwardly, a drive signal DRV is set HIGH, and a focus OPEN signal is set LOW.          After a value a counter exhibits at this time is held in a register T1, the counter is reset at zero.   Then a value the counter exhibits upon FZC+ being LOW is held in a register T2A, and a value the counter exhibits upon FZC- being HIGH is held in a register T2B.  The value of a register T3 is calculated from T1 and the average of T2A and T2B, and when the counter value becomes equal to the sum of T1 and T3, DRV is set HIGH.          After FZC- becomes LOW, OPEN is set HIGH, and the focus jump operation is completed.

Title: Emergency vehicle radio transmission system
Inventor: MAXWELL DOUGLAS G
IPC: G08G1/0965
Filed: 1996-01-30
Abstract: An apparatus for, and method of, providing an emergency signal over preselected frequencies of various radio bands such that the operators of nearby motor vehicles, or other emergency vehicles, or the like, may respond accordingly.  The preselected frequencies may be selected to correspond to radio station   frequencies,    police   frequencies,   emergency frequencies,  etc.  which  are  active  at  a  corresponding location.     However,   because  the  frequencies  may  be preselected, sensitive radio frequencies, for example those used by fire fighting units, police units and other emergency systems, may be excluded from the selection.   Consistent therewith, the selected frequencies may be provided by a user, a scanner,  or any other means  for selecting appropriate frequencies.  The power applied to the emergency signal may be adjusted such that only vehicles within a predefined range relative to the transmitting unit are affected.

Inventor: KUETHE DAVID FOREST
IPC: A22C13/00
Filed: 1996-02-06
Abstract: An improved method is disclosed for the fusing, joining or seaming of cellulosic materials. The method utilizes a hydroxide solution of selected organometallic compounds or metal oxides to rapidly crosslink opposing, overlapping cellulosic surfaces to provide secure seams. In particular, the invention is directed to the production, either on-line or off-line, of tubular cellulosic casings for the manufacture of sausages and sausage-like products. The seams according to this invention have such high shear strength that extremely narrow bond widths are possible. The narrowness of the bond site eliminates or minimizes striping or discoloration of the finished product.

Filed: 1994-10-04
Abstract: A speech synthesis system comprises a phonological converter (10), a word parser (11), a syllable parser (12), temporal and parametric interpreters (13, 14), a file (15) and a synthesizer (16). The word parser (11) and syllable parser (10) receive an input text which includes words in a defined word class. The word parser (11) parses each word to determine whether it belongs to the defined class of words. The parser (11) includes a knowledge base containing the individual morphemes utilized in the defined word class, each morpheme being a root or an affix, the binding properties of each root and each affix, the binding properties for each affix also defining the binding properties of the combination of the affix and another affix or another root, and a set of rules defining the manner in which the roots and affixes may be combined to form words. The syllable parser (10) determines the phonological features of the constituents of each syllable of the input text. The metrical parser (12) determines the stress pattern of the syllables of each word. The temporal and parametric interpreters (13, 14) interpret the phonological features together with the stress pattern to produce a series of sets of parametric values for driving the synthesizer (16). The synthesizer (16) produces a speech waveform.  If desired, the parameter values may be stored in the file (15) for later use.

Patent CA-2171335-A1 (CA)
Title: Coding methods and apparatus for scaling and filtering images using discrete cosine transforms
Inventor: WOBER MUNIB A
IPC: G06T5/20
Filed: 1994-11-29
Abstract: Image processing method and apparatus by which images in the spatial domain can be represented in the frequency domain through the use of discrete cosine transforms, conveniently operated on to achieve scaling and filtering effects while in the frequency domain, and then retransformed to the spatial domain or stored,displayed, reproduced or transmitted to distant locations for subsequent reuse. The scaling techniques which the invention utilizes can be for image enlargement by interpolation or image reduction by decimation. In the case of decimation, a filtering operation preferably is first performed in the frequency domain to avoid artifacts in the decimation process. The filtering operation is mathematically equivalent to a linear convolution in the spatial domain as a consequence of the properties of the DCT transformation. In both interpolation and decimation procedures, use is madeof a hybrid inverse discrete cosine transform in which the argument of the series of cosine terms are evaluated at values arrived at by scaling ratio considerations, rather than the usual sampling index increments. As a consequence, image points other than original image data in the spatial domain can be created or replaced by an approximation technique which involves representing them in frequency space by a series of terms that can be considered to be continuous over the range of the sampling index corresponding to that of the original image data.

Title: Wdm network with control wavelength
Inventor: MCGUIRE ALAN
IPC: H04B10/588
Filed: 1995-01-26
Abstract: A wavelength division multiplex communication  system comprises  a head station (2) and a plurality of  terminal  stations (1) interconnected by an optical fibre cable (3).  The head station (2) transmits continuous wave modulated wavelengths (.lambda.1 - .lambda.k), and a signalling wavelength (.lambda.0) which is used to indicate, in each time slot, which wavelengths in the following time slot are available for transmission.  Each terminal station (1) is arranged to receive the signalling wavelength, to determine therefrom whether the next time slot contains any data packets for that terminal station and, if so, to receive the packets.  The terminal station (1) is arranged, if it has a data packet to transmit, to determine from the signalling wavelength, whether the next time slot already contains data packets for the destination station and, if so, to avoid data collision by not transmitting its own data packet.  The terminal station (1) then determines a free wavelength (.lambda.q) from the signalling wavelength (.lambda.0), modulates the free wavelength with the data packet it is to transmit, and modifies the signalling wavelength.

Title: Absorbent and process for removing sulfur oxides from a gaseous mixture
Inventor: BHATTACHARYYA ALAKANANDA
IPC: C01F7/785
Filed: 1995-05-19
Abstract: A collapsed composition is described which is substantially composed of microcrystallites collectively of formula (I), where M2+ is a divalent metal, M3+ is a trivalent metal, and T is vanadium, tungsten, or molybdenum. The microcrystallites are so small as to be undetectable through conventional x-ray diffraction techniques, yet high resolution electron microscopy reveals that a substantial portion of the microcrystallites are composed of a solid solution having aluminum oxide molecularly dispersed in a divalent metal monoxide crystal structure. Another portion of the microcrystallites are constituted by a spinel phase. The collapsed composition is suitable as a sulfur oxide absorbent, having comparatively high capacity and comparatively fast absorption and desorption rates. The collapsed composition may be produced by heat treating a layered mixed hydroxide clay having interlayer anions in monometalate form. A sulfur oxide separation process is also presented. The process can be operated cyclicly and integrated with any of several well-known fluidized bed catalytic cracking processes.
