Title: Flexible light-shielding enclosure and method for enclosing photosensitive web end
Inventor: CLARK WILLIAM F
IPC: G03B17/30
Filed: 1992-07-21
Abstract: In use with a photosensitive web roll located inside a light-tight container having an exit slot through which the web is withdrawable, a flexible enclosure is provided for light-shielding a leading end portion of the web extending from the roll through the slot and outside the container. The enclosure comprises a flexible, substantially rectangular, opaque sleeve adapted to enclose the web end portion. The sleeve includes opposing top and bottom walls disposed in adjacent, registered, facing relationship and extending between front and rear ends and opposite lateral sides thereof. The walls are light-tightly joined together along their front ends and lateral sides, but are left unjoined and separable along their rear ends to provide an opening therebetween through which the web end portion can be inserted into the sleeve toward the joined front ends. The sleeve, with the web end portion so inserted, extends outwardly from within the container, through the exit slot, and thence outside the container, where it is folded back and secured against the container exterior.

Filed: 1992-08-14
Abstract: A cast-formed bi-metallic worm assembly of a mechanical screw press for expressing liquids from fibrous materials and a method of manufacture therefor and the product produced by the method. The worm assembly is rotatably driven by the press drive shaft and includes an outer flight body having an integral outwardly extending helical flight formed of a relatively brittle, wear-resistant homogeneous cast material and an inner hub tightly fitted and substantially fully mated within, and coextensive with, the outer flight body. The inner hub, cast formed of a more ductile, tougher homogeneous material, includes a hollow cylindrical interior surface structured for slidable engagement around and in driving connection with the drive shaft. The inner hub and outer flight body are securely engaged one to another by cast forming the outer flight body around the precast inner hub. Longitudinal lobes in a smooth undulating in and out clover leaf cross sectional pattern further increase rotational or torsionalstrength of the worm assembly without appreciably increasing internal operating stress between inner hub and outer flight body.

Title: Dna fragment sizing and sorting by laser-induced fluorescence
Inventor: KELLER RICHARD A
IPC: G01N15/14
Filed: 1993-02-12
Abstract: DNA FRAGMENT SIZING AND SORTING  BY LASER-INDUCED FLUORESCENCE     ABSTRACT A  method  is  provided  for  obtaining DNA fingerprints using  high  speed detection systems, such as flow cytometry to  determine  unique  characteristics  of DNA pieces from a selected  sample.   In one characterization the DNA piece is fragmented  at  preselected  sites to produce a plurality of DNA   fragments.    The  DNA  piece  or  the  resulting  DNA fragments   are  treated  with  a  dye  effective  to  stain stoichiometrically  the  DNA  fragments.    The fluorescence from  the  dye  in the stained fragments is then examined to generate  an  output  functionally  related to the number of nucleotides  in  each  one  of  the  DNA  fragments.  In one embodiment,  the  intensity  of  the  fluorescence emissions from  each fragment is directly proportional to the fragment length.    Additional dyes can be bound to the DNA piece and DNA  fragments  to  provide information additional to length information.    Oligonucleotide   specific   dyes   and/or hybridization  probes  can  be bound to the DNA fragments to provide   information  on  oligonucleotide  distribution  or probe hybridization to DNA fragments of different sizes.

Title: Production of improved rapeseed exhibiting a reduced saturated fatty acid content
Inventor: WONG RAYMOND S C
IPC: A01H5/10
Filed: 1991-03-27
Abstract: PRODUCTION OF IMPROVED RAPESEED EXHIBITING A REDUCED SATURATED FATTY ACID CONTENT               Abstract of the Disclosure Improved rape plants, seeds capable of forming the same, and a novel improved edible endogenous vegetable oil derived from the rapeseeds are provided.  Such plants have the ability to yield an endogenous vegetable oil having an unusually low saturated fatty acid content.  More specifically, the rape plants upon self-pollination are capable of forming rapeseeds which yield an improved vegetable oil following crushing and extraction having a saturated fatty acid content of no more than 4 percent by weight (preferably no more than 3.5 percent by weight and most preferably less than 3 percent by weight) in the form of stearic and palmitic acids based upon the total fatty acid content.  A relatively low concentration of erucic acid (as described) also is exhibited in the endogenous oil.  It has been found that the novel rape plants of the present invention can be formed by mutagenesis followed by selection as described.  The endogenous vegetable oil produced by the improved rape plants of the present invention is particularly well suited for use as a vegetable oil (e.g., for use in a salad dressing, cooking applications, etc.). Accordingly, the present invention makes possible a further significant reduction in the already relatively low concentration of saturated fatty acid commonly present in quality vegetable oils derived from rapeseeds.  In a preferred embodiment the plants additionally possess herbicide tolerance which facilitates their survival when unwanted plants which lack the reduced saturated fatty acid content are eliminated through the use of a herbicide.

Title: Feedforward amplifier for detecting distortion of an input signal
Inventor: FUKUCHI AKIO
IPC: H03F1/32
Filed: 1994-12-22
Abstract: A feedforward amplifier employs four steps to reduce distortion. In the first step, a control circuit detects the frequency of an input signal and the distortion generated by amplification of this input signal, and sets the frequency of a pilot signal output from a variable frequency oscillator to a value other than the input signal frequency and the distortion frequency and close to an average value of the input signal. Thereafter, the control circuit controls a distortiondetecting loop by using the pilot signal in the second step and controls a distortion removing loop in the third step. In the fourth step, the control circuit succeeds the control of the distortion removing loop in a normal state and further controls the distortion detecting loop only when environmental changes have occurred.

Patent CA-2147673-A1 (CA)
Inventor: REGIS HARRY J
IPC: H04M3/30
Filed: 1995-04-24
Abstract: A data acquisition apparatus, for use as a diagnostic tool in isolating the cause of chronic dropped telecommunication calls, monitors electrical signals associated with multiple telecommunication trunks.  It recognizes each occurrence of a terminated call based upon loop current cessation of a duration greater than a predetermined time interval.  Each occurrence of a terminated call, as well as electrical data indicative of which equipment terminated the call, is time-stamped and recorded.  The apparatus also time-stamps and records data regarding additional electrical events based upon pre-determined ranges of current and voltage.  It creates a chronological log of the recorded data. The apparatus interprets the recorded data and provides an easily intelligible message indicating which equipment terminated a particular call. The recorded data and the messages can then be conveniently analyzed by technicians or other personnel on a display screen to determine which equipment dropped a call and to identify significant trends regarding dropped calls.  The apparatus functions in a manner that is transparent to a customer so that it does not interfere with the customer's usage of the equipment being monitored.
