Patent CA-2124005-A1 (CA)
Inventor: BITLER JOHN A
IPC: B09B3/00
Filed: 1993-09-13
Abstract: ABSTRACT       Lead-contaminated soil and battery casings are remediated using a plasma arc furnace which pyrolyzes the soil and waste battery casings so as to form a vitrified slag and a combustible gas, respectively. The combustible gas along with volatilized lead (and other heavy metals which may be present) are transferred to, and used as a primary fuel by, a conventional smelting furnace. The volatilized lead that is entrained in the combustible gas is thus transferred to the recovery and environmental protection/control equipment associated with the smelting furnace. The soil, on the other hand, is converted into a non-toxic (i.e., according to the Toxicity Characteristic Leaching Procedure) vitrified slag by the plasma arc which may be crushed and used as a commercial material (e.g., roadway aggregate, asphalt filler material and the like) or simply transferred to a landfill where it poses no environmental threat.

Title: Synthesis of diverse and useful collections of oligonucleotides
Inventor: SHORTLE DAVID R
IPC: C07H21/04
Filed: 1993-04-13
Abstract: A new technique for generating mixtures of oligonucleotides in a single automated synthesis is taught. The method can be used to prepare mixed oligonucleotides ideally suited for creation of useful mixtures of oligo- or polypeptides or proteins.  Additionally, the technique enables insertion and/or substitution and/or deletion of a nucleotide sequence at one or more sites. For protein mutagenesis, a trinucleotide can be inserted or substituted at codon boundaries. The invented technique makes possible the encoding of all possible single amino acid insertions, or any desired mixture of substitutions and insertions.

Title: Methods of hologram constructions using computer-processed objects
Inventor: HAINES KENNETH A
IPC: G03H1/26
Filed: 1992-12-23
Abstract: Computer-processed or computer-generated objects can be used to build holograms (10) whose images are close to or stradddle the hologram surface (10). No preliminary or first hologram is required. The hologram (10) is built up from a number of contiguous, small elemental pieces (12).    Unorthodox views from inside the object (30) are required for the creation of these elements (12). One method of gen-erating the views employs unique object manipulations. The computational transformations ensure that no singularities arise and that more or less conventional modeling and ren-dering routines can be used. With a second method, a multi-plicity of conventional object views are collected. Then all pixels (22) in these conventional viewplanes (20) are reas-signed to new and different locations in the new viewplanes (20) for the element views (22). These methods may be used to build rainbow holograms or full parallax holograms.    When properly executed they are visually indistinguishable from other types.

Patent CA-2137881-A1 (CA)
Title: Microprocessor-based temperature control circuit
Inventor: MULLIN PAUL S
IPC: F23N5/10
Filed: 1994-12-12
Abstract: A temperature control circuit which is capable of operating a microprocessor on a very low voltage source.  The temperature control circuit uses a pair of field effect transistors and a zener diode in an oscillator circuit to amplify the source voltage.  A microprocessor is supplied by the amplified source voltage, and is connected through a transistor to a temperature sensing portion of the circuit.  The microprocessor uses the transistor to turn the power to the temperature sensing circuit portion off between temperature samples.  By turning the temperature sensing circuit power off between samples, the average power drain by the control circuit is an amount that can be met by the amplified voltage from the low voltage source.

Abstract: A dough cutting and packing apparatus for cutting a sheet of dough into dough pieces and transferring the dough pieces to containers. A cutting unit is defined by a plurality of cutting plates having dough retaining openings. The sheet of dough is partially sheeted into the dough retaining openings by an initial compressor roll which is spaced from an upper surface of the cutting plates. A terminal compressor roll contacts the upper surface of the cutting plates, and acts to sheet a remaining portion of the dough sheet into the dough retaining openings to divide the dough sheet into a plurality of dough pieces retained in the openings. The initial compressor roll is driven at a peripheral rate of speed that exceeds an instantaneous liner rate of speed of the cutting unit. The terminal compressor roll is frictionally driven via contact with the cutting plates such that a peripheral rate of speed of the terminal compressor matches the linear rate of speed of the cutting unit. A packing mechanism transfers the dough pieces from the cutting unit to the containers as the containers are moved relative to the packing mechanism by a plurality of flighted augers.
Patent CA-2156403-A1 (CA)
Inventor: SYDOR JOHN TOM
IPC: H01Q11/08
Filed: 1994-02-04
Abstract: An antenna suitable for mounting upon vehicles, vessels or aircraft for communication via satellites comprises a conductive ground plane (18; 124) and a radiator element in the form of a conductor (20; 120) helically wound to define a frust-conical shape with the ground plane (18; 124) as its base. The conductor may be formed upon a dielectric substrate (16; 118) in the shape of a truncated cone. The dimensions of the antenna element are selected so that the pitch angle (.alpha.) of the radiator element varies between a minimum (.alpha.MIN) of about 6 degrees and a (.alpha.MAX) of about 8 degrees. The required pitch angle (.alpha.) may be achieved when the cone angle (?) of the frusto-conical shape is between about 5 degrees and about 20 degrees and the mean diameter of the frust-conical shape is between about 0.3 and about 0.47 of a mean operational wavelength (.lambda.) predetermined for the antenna.  The length of the radiator element (20; 120) is selected to be the minimum needed to sustain a wave. Optimum performance with compact size is attained when the ground plane is about two thirds of the operational wavelength, the cone angle is about 10 degrees and the maximum diameter of the frusto-conical shape is equal to about one half of the wavelength.

Patent CA-2163751-A1 (CA)
Inventor: GONZALEZ HECTOR F
IPC: G11B23/50
Filed: 1994-05-24
Abstract: The present invention provides an apparatus using dry cleaning techniques for cleaning a read/write head (14) of the contact transducing type such as found on computer data backup tape drive systems. The apparatus includes a housing (30) enclosing a supply reel (40) holding a supply of cleaning tape, a takeup reel (42) for holding used or soiled cleaning tape, and a gear train for transmitting rotary power at a reduced rotational speed from an external power source such as the tape drive capstan to the takeup reel. The gear train includes a plurality of gears that constitute a gear reduction system such that the cleaning tape can be driven past the head at an effective cleaning speed which is substantially less than the normal read/write speed of the tape drive. The apparatus further includes a movable shutter mechanism (122) for blocking one of a pair of light paths between a light emitter (94, 96) and a light sensor forming part of the tape drive system, thereby providing a unique signal to the tape drive. The shutter mechanism is activated upon insertion into the tape drive by the tensioning of the cleaning tape against the shutter mechanism so as to move it into operational, light-path blocking position against the influence of a biasing spring, thereby alerting the tape drive that a cleaning apparatus has been inserted into the tape drive so that the cleaning cycle operates for a tape drive manufacturer preferred time period.
