Inventor: HUSCROFT CHARLES KEVIN
IPC: H04Q11/04
Filed: 1995-06-02
Granted: 1999-09-14
Abstract: A method of generating output clock pulses using a phase locked loop which includes a voltage controlled oscillator (VCO) is comprised of providing a sequence of data pulses and a sequence of reference clock pulses, resetting the phase locked loop to force the VCO to its lowest operating frequency, releasing reset of the phase locked loop and forcing the VCO to lock to a multiple of the frequency of the reference clock pulses, detecting the presence of data pulse transitions, in the event of detection of data pulse transitions, forcing the VCO to lock to the data pulses, the outputting output clock pulses from the phase locked loop.

Title: Apparatus and method for continuous processing of granular materials using microwaves
Inventor: BALBAA IBRAHIM S
IPC: F27D99/00
Filed: 1995-09-29
Granted: 2001-02-13
Abstract: An apparatus and method for the continuous processing of a granular material in a wet or dry state. The apparatus comprises first and second heating chambers, and the heating energy is provided by microwave energy. The first chamber preheats the granular material to lower the moisture content. The second chamber heats the granular material to the desired high temperature, for example, 800°C for the reactivation of carbon. The first and second chambers are arranged in a vertical orientation to allow gravity to assist in the flow of material through the chambers. The flow of material is controlled by a valve positioned at the outlet of the second chamber. The apparatus is suitable for the reactivation of metallurgical carbon and the heating of other granular materials such as ceramics and glass powders.

Granted: 1999-08-17
Abstract: This invention relates to a new and improved design associated with the fabrication and construction of a needleless transfer system wherein through the use of a unique valve mechanism there is avoided the necessity to utilize a needle in conjunction with a syringe for purposes of transferring and/or injecting  a liquid medium from one environment into another environment. By having the valve mechanism comprise a hollow enclosure which has contained therein a compressible structure which acts both as a filter and as a mechanism to allow for the selective flow of a liquid medium through the system in a singular direction, the capabilities of the needleless transfer system are achieved.

Title: Frequency plan for a cellular network
Inventor: FARUQUE SALEH MOHAMED
IPC: H04B7/26
Filed: 1994-06-15
Granted: 1999-08-24
Abstract: An N=3 frequency plan for 60 degree sector transmit sector receive (STSR) cell sites is based upon dividing avail-able channels into 18 frequency groups. Frequency assign-ment is in accordance with an odd-even cyclic distribution of channels which provides a three-channel separation between sectors within a cell and an eight-channel separation between cells. This ensures adequate channel isolation between sec-tors and improved adjacent channel C/I performance through-out the network.  The N=3 frequency plan increases chan-nel capacity by approximately 38 % in AMPS and 114 % in TDMA-3.

Abstract: On fait varier la hauteur tonale de signaux vocaux synthétisés en séparant les signaux vocaux en une composante spectrale et une composante d'excitation. On multiplie cette dernière par une série de fonctions de fenêtre se chevauchant qui, dans le cas d'une parole voisée, sont synchrones avec les informations de repère d'horloge de hauteur tonale correspondant au moins approximativement à des instants d'excitation vocale, pour la décomposer en segments de parole affichés dans une fenêtre qui sont ré-additionnés ensemble après l'application d'un décalage temps pouvant être commandé. On recombine ensuite les composantes spectrales et d'excitation. La multiplication utilise au moins deux fenêtres par période de hauteur tonale, chacune ayant une durée inférieure à une période de hauteur tonale, ou bien dans une autre forme d'exécution, chaque fenêtre a une durée inférieure à deux fois la période de hauteur tonale entre des repères d'horloge et est asymétrique au voisinage du repère d'horloge.

Abstract: A method for making a sausage product. The method comprises stuffing a wet sausage meat product into a food casing, vertically hanging the stuffed sausage meat product, and drying and curing the stuffed sausage meat product at least partly while the stuffed sausage meat product is vertically hung. In a unique aspect, the food casing comprises a tubular film regenerated from a solution of cellulose. After regeneration, the tubular film is longitudinally stretched by from 8 to 40 percent and transversely stretched by from -20 to +20 percent while wet, and the stretch is maintained during drying. The stretch is sufficient to increase the surface area of the casing by at least 10 percent. The transverse stretch is less than 75 percent of the longitudinal stretch. As a result of using the unique casing, dimensional stability of the vertically hung product is improved. The invention further includes a sausage product comprising wet sausage meat product stuffed in a food casing and vertically hung for curing and drying. The food casing comprising a tubular film regenerated from a solution of cellulose stretched and dried as previously described.

Abstract: A method and apparatus are described for determining the amount of canting necessary to correct the ski boot-ski interface to compensate for inherent misalignment between a skier's lower leg and the bottom of the sole of his or her boots. The skier's foot is secured in the boot, and the boot is secured on a platform freely rotatable about a longitudinal centerline axis.   A rod also freely rotatable about the same axis is centered with respect to the knee by a knee clamp attached to the rod. A  pointer affixed to the rod is used to accurately determine the angle between the rod and platform on a scale extending from the boot platform. This angle is then used to guide the placement of shims or the employment of other means to effect the desired orientation of the knee, and consequently the lower leg, relative to the ski, for optimum control.

Abstract: It is an object of the present invention to ensure that even when slipping is generated during the upshifting from a first gear shift stage to a second gear shift stage on ice or the like, a control for prohibiting the upshifting from the second gear shift stage to a third gear shift stage can be carried out precisely. A control system is designed so that when a slipping state is detected on ice having a lower road surface friction coefficient or the like by a slipping state determining means, the upshifting of an automatic transmission from a second gear shift stage to a third gear shift stage is prohibited. In this control system, the time required for the upshifting from a first gear shift stage to the second gear shift stage is measured. If such time is shorter than a first predetermined time, it is determined that a slipping has been generated during the upshifting, and the upshifting from the second gear shift stage to the third gear shift stage is prohibited for a second predetermined time. Thus, even when the determination of the slipping state by the slipping-state determining means is not in time, the further upshifting of the automatic transmission is prohibited. Therefore, it is possible to reliably avoid the carrying-out of undesirable upshifting.

Title: Toe-to-heel oil recovery process
Inventor: AYASSE CONRAD
IPC: E21B43/20
Filed: 1998-09-02
Granted: 2002-06-18
Abstract: In an underground ail reservoir, an injection well is completed low in the reservoir and a production well is provided having a horizontal leg completed relatively high in the reservoir and a vertical leg completed low in the reservoir. Water is injected with the vertical leg open and the horizontal leg closed, so that a displacement front advances in an under-riding manner between the wells and oil is produced through the vertical leg. Once the water break-through in the vertical leg occurs, it is closed and the horizontal leg is opened. A rising, horizontal, gravity-stable displacement front then advances upwardly toward the horizontal leg, through which oil is produced. The open horizontal leg acts as a low pressure sink to induce the horizontal displacement front to advance up toward it. This two-stage process is characterized by a good vertical and lateral sweep. In a slightly modified version, water is injected with the vertical leg closed and the horizontal leg open so that a gravity-stable displacement front advances both laterally and vertically with a relatively upright position of a displacement front. In this version (one stage process) the process is also characterized by a good vertical and lateral sweep.
