Inventor: OSHIDA MAMORU
IPC: G21K1/04
Filed: 1990-10-09
Abstract: An apparatus for controlling a dose of irradiation to a product comprises a first barrier body arranged between a conveyer and an irradiation device located opposite to the conveyer and a second barrier body arranged in juxtaposition with that first barrier body, both bodies being slidably movable along the running direction of the conveyer. A distance between the first barrier body and the second barrier body is adjustable for controlling the dose of irradiation to the product. Preferably at least one of the first and second barrier bodies has a conduit integrally formed therein for circulation of cooling fluid within the body, and the first and second barrier bodies have a same configuration. Each of the barrier bodies comprises a plurality of oblique sections which are arranged obliquely to the running direction of the conveyer.

Title: Delay initiator for blasting
Inventor: TRUE DONALD C
IPC: F42B3/16
Filed: 1991-06-14
Abstract: A novel initiator (blasting cap) for explosives is provided. The initiator, which may be electric or non-electric, comprises a principal tubular metal shell containing a base charge, a delay charge, a priming charge and an ignition means, wherein the base charge and priming charge are housed within a reduced diameter tubular metal shell, which reduced diameter shell is located within but separated from the principal shell by a void space. The construction results in a markedly improved resistance against shock initiation.
Patent CA-2045104-A1 (CA)
Inventor: DETWEILER CHARLES A
IPC: E05B65/12
Filed: 1991-06-20
Abstract: ABSTRACT OF THE DISCLOSURE A remotely actuated solenoid latch apparatus adapted for use in motor vehicle applications is disclosed. The solenoid latch apparatus includes a solenoid having an armature movable between a first position displaced from a pole piece to define a working air gap therebetween to a second position attracted toward the pole piece. A solenoid winding encircles the pole piece and the armature for attracting the armature toward the pole piece upon energization thereof. A latch member is associated with the movable armature for lockingly engaging a striker bar when the armature is in one position and releasably disengaging the striker bar when the armature is in the other position. The present invention is self-compensating to align the latch member relative to the striker bar, prior to engagement therewith, to compensate for alignment variation between the latch member and the striker bar. The pole piece is movable to provide a relatively constant air gap upon alignment of the latch member relative to the striker bar when the armature is displaced from the pole piece.

Abstract: ABSTRACT OF THE DISCLOSURE              Disclosed is a thermoplastic flexible film suitable for wrapping static sensitive devices such as electronic cir-cuit boards.   The film is made of an inherently hydrophilic polyether block amide  copolymer  in blend with a compatible polymer.   Compatible polymers typically are amide polymers or are acid copolymers, such as the nylons or ionomers.  The film does not have a degree of hydrophilicity unsuitable for packag-ing static  sensitive devices.   Yet  the  film is antistatic without requiring the addition of an antistatic agent.     6/910422.Y/TXTJLS

Filed: 1992-06-16
Abstract: METHOD OF ELECTROSTATICALLY COATING NONCONDUCTIVE PANELS            ABSTRACT OF THE DISCLOSURE         Plastic automotive panels are painted electrostatically by coating the rear of the panel with conductive material to serve as the grounded terminus of an electrostatic paint deposition field and paint is sprayed onto the front of the panel by conventional electrostatic spray guns.  The coating is applied to the panels by spraying a conductive salt or a conductive primer to the rear surface and allowed to dry, or the panel is formed with the conductive coating molded in situ.  In the latter case, conductive material is sprayed onto a mold surface or a metal foil or metallized plastic sheet is inserted into the mold before the part is formed to result in a panel with a conductive rear surface.  Also in-mold coating can be used to apply a conductive coating during the formation of a plastic panel.

Title: Electric motor
Inventor: LANGE ANDREAS
IPC: H02K21/12
Filed: 1991-10-15
Abstract: The invention relates to a power-converted fed synchronous motor with a rotor (2) having at least one pole structure (12) with adjacent rows consisting alternately of magnetised permanent magnets (13) and intermediate soft iron components (14), whereby opposite each pole structure (12) is a two-part (6, 7) stator (5). The arrangement is such that the circumferential exciting winding (8) in the stator (5) is concentrated on only a part (6) of the stator (5), whereby the other stator (7) has no windings. The annular winding (8) is preferably fitted in the outer stator (6) while the inner stator (7) serves only as a magnetic reaction component within the rotor (2) to produce the transverse magnetic flux. This simplifies the wiring to the annular winding and makes for a simpler winding structure.

Title: Method for detection of borrelia burgdorferi, purified antigen thereof and antibody capable of binding therewith
Inventor: DORWARD DAVID W
IPC: C07K19/00
Filed: 1991-02-27
Abstract: The invention relates to novel antigens associated with Borrelia burgdorferi which are exported (or shed) in vivo and whose detection is a means of diagnosing Lyme disease. The antigens are extracellular membrane vesicles and other bioproducts including the major extracellular protein. The invention is further directed to antibodies, monoclonal and/or polyclonal, labeled and/or unlabeled, that react with the antigens and to a method of diagnosing Lyme disease by detecting the antigens in a biological sample taken from a host using the antibodies in conventional immunoassay formats. The invention further relates to kits, for the diagnosis of Lyme disease, comprising the antibodies and ancillary reagents. The advantage of the antibodies used in the invention is that they react with the antigens from geographically diverse strains of Borrelia burgdorferi, but do not react with antigens from related Borrelia spirochetes.

Title: Frequency scaler for synchronous digital clock
Inventor: SASAKI LAWRENCE H
IPC: H03K23/64
Filed: 1991-04-24
Abstract: A frequency scaler comprising a plurality of flip-flops, varies its frequency division to correct phase by 0.5 clock cycle.   Each flip-flop is continuously and synchronously responsive to either a rising or a falling edge of the clock pulses.  Normally, the scaler's state transits along one of two loops, which generate output pulses having identical repetition rates.   When a control signal is applied, the scaler's state transits from one loop to the other, generating at least one output at an alternative repetition rate.   The alternative repetition rate is either lower or higher than the identical repetition rate by an integral number of half cycles of the input clock pulses.   Where there are two control signals, a lower or higher alternative repetition rate can be selected.  Since the flip-flops are responsive to either edge of the clock pulses without clock gating interruptions, there is no jitter and the scaler's robustness is improved.  Also the clock frequency can be effectively halved.               -i-

Filed: 1992-10-09
Abstract: Information collected from the primary sensor and a plurality of the reference sensors is compared to derive correlation  data.  A matric, representing correlation data in the time  domain or cross-spectral density information in the frequency domain, is constructed based on the computed correlation  data. The matrix is transformed to a diagonal matrix and a threshold value is selected with reference to one of the larger  eigenvalues of the diagonalized matrix.  Components of the diagonalized matrix are compared to the threshold and values greater than the threshold are used together with primary sensor correlation data to compute Wiener filter constants.  The reference sensor outputs are modified by the filter constants and modified sensor outputs are substracted from the primary sensor output. A noise-cancelled output signal is then synthesized.
