Patent CA-2079630-A1 (CA)
Inventor: WEEBER WILLIAM B
IPC: H04J3/07
Filed: 1992-10-01
Abstract: PATENT     ABSTRACT OF THE DISCLOSURE    An in-line piece-wise linear desynchronizer eliminates the need for very low bandwidth analog, phase lock loops to smooth phase jumps caused by pointer changes such as those associated with a DS-1 signal mapped into a SONET VT 1.5 payload.  The desynchronizer comprises a digital elastic store position detection circuit, a digital frame induced jitter filter, a digital leak rate filter, and a digital frequency synthesizer (VCO).  The magnitude of the jitter can be reduced to any level by adjusting the digital VCO resolution and digital leak rate filter time constant.  The desynchronizer produces a digitally synthesized output clock which can then be coupled to an analog/digital phase lock loop for smoothing high frequency jitter in the synthesized output clock, thereby providing an in-line interface function.

Title: Automatic constant wavelength holographic exposure system
Inventor: ARNS JAMES A
IPC: G03H1/04
Filed: 1992-11-24
Abstract: A hologram exposure system that includes a spherically curved  mirror  surface  positioned  adjacent  a  sub-strate/hologram assembly that includes a spherically curved hologram recording layer supported by a spherically curved substrate surface, wherein the spherically curved mirror surface is concentric with the spherically curved substrate surface.  A first rotating means provides for rotation of the curved mirror surface about a first axis that passes through  (a)  the center of curvature of the spherically curved substrate surface that supports the hologram record-ing layer, and (b) a point on the hologram recording layer that allows for convenient rotation about the first axis; and a second rotating means provides for rotation of the curved mirror surface about a second axis that is ortho-gonal to the first axis and intersects the first axis at the center of curvature of the substrate surface that supports the hologram recording layer.  The desired holo-gram area of the recording layer is holographically exposed by  controllably  rotating  the  mirror/recording  layer/-substrate assembly about the first and second axes while illuminating the assembly with an exposure beam that is incident on the recording layer at the intersection of the recording layer with said first axis and passes through the recording layer to be reflected by said mirror surface.

IPC: C10L10/10
Filed: 1991-05-28
Abstract: Blended gasolines are produced by the mixing of a natural gasoline component and at least one octane-enhancing component. The mix is weathered during the blending operation to remove lightweight hydrocarbons comprising one- to four-carbon components. The lightweight hydrocarbons, which preferably constitute less than 3 percent of the blended gasoline, can be recovered to generate power to run the process. The liquid gasoline mixture is formulated to produce a desired octane rating, an environmentally acceptable vapor pressure, and a mix which, when burnt in an internal combustion engine, produces a minimum amount of pollutants.

Title: System for securing mobile telephones from unauthorized transmission
Inventor: CASSIDY BARRIE
IPC: H04W88/02
Filed: 1993-07-05
Abstract: ABSTRACT            A mobile telephone incorporating the invention includes in its transmitter circuitry a system for preventing unauthorized calls from being transmitted by the telephone, by ensures that the telephone transmits only service and call requests which included the electronic serial number ("ESN") assigned to the telephone by the manufacturer, which is permanently stored in the telephone in an unalterable ESN memory.  To make an unauthorized call, a user circumvents this memory by having the telephone transmitter retrieve an unauthorized ESN from another, user programmed memory location as the transmitter is formulating a service or call request.  The system, which is included in the telephone transmitter includes ESN detection circuitry which determines the bit position of an ESN in a service or call request and either (i) compares the ESN in the request with the assigned ESN stored in the telephone and transmits only requests which contain an ESN which matches the assigned ESN, or (ii) directly substitutes the assigned ESN into each request as the request is being transmitted.  In another embodiment, the ESN memory is included in the transmitter as is "request-formatting" circuitry.  The transmitter formatting circuitry formats a request using the internal ESN and message information supplied to it by, for example, a user, and transmits the request.

Title: Solid state peripheral storage device
Inventor: HSU JUEI-CHI
IPC: G11C29/00
Filed: 1993-11-08
Abstract: A solid state peripheral storage device receives an LSN address from a computer system and provides a mapping to a PSN data.  The PSN data addresses memory units which are made out of solid state floating gate storage cells. In addition, a microsequencer controls the operation of the translation of the mapping of the LSN to PSN.  Through the use of the mapping of LSN to PSN, defective sectors in the memory units can be mapped out and fresh, unused, defective-free sectors can then be replaced, all automatically, without user intervention. Finally, the microsequencer has error recovery routines to further enhance the reliability of the peripheral device.

Title: Apparatus and methods for bursting interstacked longitudinally offset form sets from continuous webs
Inventor: RING ROBERT S
IPC: B65H35/10
Filed: 1993-09-22
Abstract: ABSTRACT OF THE DISCLOSURE   Interstacked longitudinally offset form sets from continuous webs are fed through upstream low speed rollers and downstream rollers, with a breaker bar disposed between the roller pairs.  The upper roller of the slow roller pairis mounted eccentrically to engage the webs between the upper and lower rollers of the slow roller pair once for each revolution of the upper roller. When a leading portion of one web enters the nip of the downstream rollers, the eccentrically mounted upper low speed roller engages the webs and the downstream roller pairs are rotated at a higher speed to create sufficient tension in the form between the pairs of rollers such that the form engages against the breaker blade to burst the form from the web.  Upon bursting, the eccentric low speed roller disengages or opens relative to the webs and the leading portion of a form of the other web engages in the nip of the downstream roller pair whereupon the bursting of the form from the second web is accomplished.
