Abstract: Methods are provided for fitting an eyeglass frame to a wearer. The methods include the steps of providing frames which have been classified into predetermined temple to temple size ranges based on the temple to temple frame sizes of the frames. The wearer's temple to temple head size is measured using a device which indicates at least one temple to temple size range as corresponding to the wearer. Eyeglass frames are fitted to the wearer selected from the frames which fall within the temple to temple size ranges corresponding to the wearer. There is also provided a frame measurement platform for measuring the perpendicular distance between the two temples of an open eyeglass frame, and a method for using such a device. The platform includes a support, two spaced-apart reference members which are moveable with respect to each other, and means for measuring. The reference members define respective temple measuring planes which are substantially perpendicular to a reference measuring plane defined by the support. The measuring means is used to measure the perpendicular distance between temples of an open eyeglass frame.

Abstract: The present invention is hydrophobic silica gels and a method for their preparation under neutral conditions. The method comprises two steps, where in the first step of the pH of a silic hydrosol is adjusted with a base to within a range of pH 3 to pH 7 to facilitate formation of a silica hydrogel. In the second step, the silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the silica hydrogel. In a preferred method, in a third step the hydrophobic silica gel is contacted with a sufficient quantity of a water-immiscible organic solvent to convert the hydrophobic silica hydrogel into a hydrophobic silica organogel.

Title: Generating searchable data entries and applications therefore
Inventor: ABDAT MOURAD
IPC: G11C15/00
Filed: 1999-11-30
Granted: 2007-04-10
Abstract: New techniques for generating entries in a content addressable memory (CAM) capable of comparison operations such as "greater than" and "less than" decisions are described. The techniques can be used with binary or ternary CAMS. The number of CAM entries needed to implement such decisions is drastically reduced for both binary and ternary CAMS. In the case of binary CAMS, one or multiple searches are needed to perform the comparisons, while in the case of ternary CAMS a tradeoff between the number of CAM entries and the number of searches can be found. As an example, a method of classifying data networking packets is implemented using the new techniques. A packet classifier based on subfields of a packet header is also described.

Title: Production of low sulfur syngas from natural gas with c4+/c5+ hydrocarbon recovery
Inventor: SAY GEOFFREY RHYS
IPC: B01D53/14
Filed: 1999-01-15
Granted: 2008-10-07
Abstract: Sour natural gas is processed to remove the sulfur compounds and recover C4+/C5+ hydrocarbons by scrubbing the gas with an amine solution to remove most of the sulfur, followed cooling the gas to remove C4+/C5+ hydrocarbons and more sulfur compounds as liquid condensate to produce a gas having less than 20 vppm of total sulfur. The condensate is sent to a fractionator to recover the C4+/C5+  hydrocarbons. The sulfur and hydrocarbon reduced gas is contacted first with zinc oxide and then nickel, to produce a gas having less than vppb of total sulfur which is passed into a synthesis gas generating unit to form a very low sulfur synthesis gas comprising a mixture of H2 and CO. This synthesis gas is useful for hydrocarbon synthesis with increased life of the hydrocarbon synthesis catalyst and greater hydrocarbon production from the hydrocarbon synthesis reactor. Contacting the synthesis gas with zinc oxide further reduces the sulfur content to below 3 vppb.

Abstract: A system of the present invention uses small swing differential source synchronous voltage and timing reference (SSVTR and /SSVTR) signals to compare single-ended signals of the same slew rate generated at the same time from the same integrated circuit for high frequency signaling. The SSVTR and /SSVTR signals toggle every time the valid signals are driven by the transmitting integrated circuit. Each signal receiver includes two comparators, one for comparing the signal against SSVTR and the other for comparing the signal against /SSVTR. A present signal binary value determines which comparator is coupled to the receiver output, optionally by using XOR logic with SSVTR and /SSVTR. The coupled comparator in the receiver detects whether change in signal binary value occurred or not until SSVTR and /SSVTR have changed their binary value. The same comparator is coupled if the signal transitions. The comparator is de-coupled if no transition occurs. The system may use a first set of oscillating references on a first bus for detecting transitions in control information and a second set of oscillating references for detecting transitions in data information.

Abstract: Following second phase steam assisted gravity drainage operation using a co-operating pair of steam injection and fluid production wells, ste am injection is terminated while flowing fluid production is continued, to draw down the reservoir pressure and flash steam in situ. Then a downhole pump is actuated to produce reservoir fluid and further reduce the reservoir pressure; thereby generating additional steam in situ. As a result of these steps, an additional recovery of oil is realized, using residual heat remaining in the reservoir at the end of steam injection and incremental steam generated in situ by pressure reduction obtained by pumping.

Abstract: A rail-car status-indicating assembly is provided for mounting to the axles of railcars. A solenoid and a magnet are part of the assembly installed each to one of a non-rotating structure and a rotating structure which co-rotates with the axle so that each time the solenoid enters the magnets field a current is induced. Preferably, a housing forms the rotating structure for protecting the inductive components. A bearing and pendulum are mounted within the housing to form a non-rotating structure. Magnetically induced co-rotation is eliminated by mounting of the electrical components to an offset pivoted structure. One form of low-power status device is light emitting diodes, electrically connected to the solenoid for repeated emission of light visible to oncoming motorists. Other embodiments include use of low power temperature sensors and the use of LEDs to transmit two or more status condition or via RF transceivers.  Alternatively, the housing forms the non-rotating pendulum structure and the axle rotates a rotary member bearing one of either the solenoid or magnet.
