Abstract: By utilizing the process of the present invention a carbon black/resin masterbatch powder can be easily prepared on a commercial scale.  This invention more specifically discloses a process for making a resin/carbon black masterbatch powder which comprises the steps of: (1) mixing the carbon black and the resin in an aqueous medium at an elevated temperature to produce an aqueous dispersion, with the proviso that the elevated temperature is above the melting point of the resin in the case of crystalline resins and with the proviso that the elevated temperature is above the softening point of the resin in the case of amorphous resins; (2) cooling the aqueous dispersion to a temperature which is below the melting point or the softening point of the resin; and (3) recovering the masterbatch powder from the aqueous dispersion. By utilizing the technique of this invention resin-composite particulates of syndiotactic-1,2-polybutadiene and carbon black can be easily prepared. Such resin-composite particulates are reported to be useful in making tire tread formulations which provide improved tire performance characteristics on ice and snow.

Title: A method and apparatus for determining the erythrocyte sedimentation rate
Inventor: DUFRESNE CHRISTOPHER
IPC: G01N15/05
Filed: 1996-07-19
Abstract: In an improved method for measuring the erythrocyte sedimentation rate (ESR) a pre-evacuated test tube (T) is used to collect a blood specimen. The tube (T) ismade of a material such as glass or plastics and contains an anticoagulant/mixing agent. For testing, the tube (T) is put into a rack (1) and loaded into an instrument which mixes the specimen briefly. An optical sensor (3) is used to record the loca-tion of the blood/air meniscus at initial time. At subsequent time intervals thereafter for periods up to 20 minutes or less, the optical sensor (3) identifies and measures the location of the cell/plasma interface (I) within an observation window constituting a minor portion of the overall length of the tube (T). The measuredvalue is then converted by an algorithm (10, 11) to the value which would be obtained using the classical Westergren method.

Inventor: MATHIS GARY L
IPC: G01V5/12
Filed: 1996-08-27
Abstract: A method for determining density of a formation. The method includes irradiating the formation with gamma rays having energy consistent with Compton scattering. Gamma rays are measured at axially spaced apart locations. Two of the axially spaced apart locations are at an equal distance and in opposite directions relative to the source of gamma rays. The distance is smaller than the spacing of another one of the spaced apart locations. An apparent density for each spaced apart location is determined from the counts. Differences are calculated in apparent density between each one of the spaced apart locations, and a correction factor is determined for apparent density at each spaced apart location, thereby determining the density of the earth formation. In a preferred embodiment, determining correction factors is performed by a neural network using the differences in apparent density as an input vector.

Abstract: A system and method are provided for automatically labeling an electronic price label (EPL) tag. A customer data file (CDF) includes a batch of records including a product description and corresponding record number. Labels are printed sequentially for the records contained in the CDF and are automatically applied to the EPL tags in a continuous process. The record number is printed on the tag in the form of a corresponding bar code, and the record number bar code and a serial number bar code also contained on the tag are automatically read. The CDF is updated for correlating the serial number with a respective record number. Optical scanners are provided for uncovering defects in visual displays of the tags, misapplied labels, and unreadable bar codes which are thenrejected. A makeup batch of records is identified from the CDF to identity record numbers without corresponding serial numbers, with the makeup batch then being used to repeat the printing and applying steps for fully processing the first batch.

Title: Seat Mounted Side Impact Airbags
Inventor: BUNKER SANFORD MARK
IPC: B60R21/201
Filed: 1996-09-16
Abstract: An airbag module and mounting. An inflator is received within the cushion, such that the cushion wraps around the back side of the inflator. The inflator includes an extending fastener, and possibly an extending tab. The inflator, or the tab, is partially retained by a receiving structure on the seat. The fastener extends through another section of the seat, such that securing the fastener secures the entire inflator. Additionally, since the cushion surrounds the inflator, the cushion is also secured. To maintain the cushion in the folded condition, a frangible wrap extends around the cushion and inflator. Upon inflation, the frangible wrap, and the seat covering, are torn by the expanding cushion to permit further expansion. This arrangement eliminates the need for a protective housing for the inflator and cushion. Other mounting arrangements are also provided.

Abstract: A polyphase dynamoelectric machine (10) such as a switched reluctance motor has a stator assembly (12) and a rotor assembly (14). The rotor assembly is movable with respect to the stator assembly. The stator assembly includes a stator (16) having a plurality of stator poles (18). The rotor assembly includes a rotor (20) having a plurality of rotor poles (22). The stator assembly further includes a plurality of separately energizable stator windings (24) associated with the respective machine phases. These stator windings are energized and de-energized in a predetermined sequential manner to sequentially activate and deactivate themachine phases. Energization and de-energization of the respective stator windings is at least partially determined as a function of the machine's instantaneous rotor position. The machine includes a processor (26) for determining the rotor position. The processor monitors the waveform of a circulating current coupled from an energized stator winding for an active machine phase into a de-energized stator winding for an inactive machine phase. Respective energized and de-energized stator windings are interconnected to forma closed circuit path by which the current in the energized stator winding is coupled into the de-energized stator winding. Monitoring the resultant current waveform provides an indication of rotor position, and the processor uses this information to energize and de-energize the stator windings.

Title: Method for making paper
Inventor: DONDEYNE MARCEL
IPC: D21H17/66
Filed: 1996-03-28
Abstract: The invention relates to a new process for the manufacture of paper which employs, in the fibrous composition, a cationic starch exhibiting a high level of fixed nitrogen, namely greater than 0.95 %, and a polyaluminium compound, such as a (basic) aluminum polychloride or an aluminium polychlorosulphate. This process makes it possible, including under difficult conditions (fibrous composition based on old papers, significant closure of the circuits), to improve the level of retention of starch and the physical characteristics of the paper, indeed to increase the machine speed by dispensing with the surface treatment optionally applied to the paper. The process according to the invention is particularly suitable for the manufacture of paper for graphical use or of paper for wrapping or packaging and very particularly of fluting paper or of liner paper for corrugated fibreboard.
Patent CA-2190925-A1 (CA)
Inventor: MUHLENBERG LAMBERT
IPC: H04N1/41
Filed: 1996-11-21
Abstract: A system and method for more efficient data compression is provided, being particularly applicable to use in battery powered devices where there is a premium on minimizing the steps required and the amount of memory that must be dedicated to the task. The invention utilizes the technique of determining a delta or difference between each successive sample of the signal and the prior sample; examining the delta signals for a block comprising a predetermined number of such delta signals; determining the largest absolute delta value; determining the number of bits required to store such largest delta; and then storing both the determined number of bits and each delta value which is encoded with such determined number of bits. The block size is chosen to correspond to the type of signals being processed, and for typical medical applications is selected as a size within the range of 5-12 samples. The compressed data can be efficiently transmitted, such as from an implanted medical device to an external receiver, and decompressed by algebraically adding each delta to the value of the prior sample to recreate the respective samples and the signal.
