Patent CA-2172083-A1 (CA)
Inventor: WELCH HAROLD D
IPC: B32B3/28
Filed: 1996-03-19
Abstract: A laminator for applying pre-printed labels to a single face corrugated web to form double face corrugated sheets utilizes a control system including accurate leading and trailing edge detection of the labels to custom cut the corrugated web to match the label length in a manner which assures complete and uniform coverage of the glued flute tips of the corrugated web by the labels.  The labels are fed non-stop as a series of spaced sheets into a laminating nip to join the leading edge of the traveling single face corrugated web.  A positioning nip upstream of the laminating nip varies the speed of the incoming sheets to accurately match sheet leading edge to web leading edge. Detection of the sheet trailing edge triggers operation of the web cut-off knife to accurately match the corresponding cut trailing edge.

Abstract: The invention pertains to a detector arrangement (1) in-cluded in a preventive safety sys-tem that can be used within a process in which loosely-formed process material is produced in a first unit (2) and transported (3) to a receiving, second unit (2), wherein the treatment to which the material is subjected in said first unit is liable to produce one or more discrete particles which have a temperature sufficiently high to initiate fire and/or explo-sion within at least the second part or unit (2). The necessary transportation of the loose ma-terial between the first unit (1) and the second unit (2) is ef-fected along a path which in-cludes a stabilizing zone (7), a high-temperature particle indicat-ing zone (8), and an extinguish-ing zone (9), wherein the indi-cating zone includes one or more particle sensors (10). The sensors coact with an indicating and activating unit (12) such that indication by the sensors of the presence of a high-temperature particle in said indicating and activating unit will activate a device which is associated with the extinguishing zone and which functions to deliver an extin-guishing agent and/or to remove particles (15). The sensing lobes of two sensor units (105, 107) cover a cross section of the transportation path. The indicating and activating unit (12) is adapted to evaluate the sensed intensity from each of said sensor units (105, 107) and to coordinate received intensity-dependent signals so as to calculate and establish on the basis thereof the liability of the particle to initiate fire and/or explosion.

Abstract: Dans un système (10) d'administration transdermique de médicament, une matière d'encapsulation utilisée pour enrober des granules (24) de médicament régule la libération d'un ingrédient actif. Ledit ingrédient actif est libéré dans une matrice (20) à rétention d'eau qui agit à la manière d'un réservoir, et la pénétration transdermique du médicament est commandée par le gradient de concentration qui en résulte. Ledit système d'administration est enfermé dans un timbre comportant une enveloppe (12) composite qui agit comme un pansement occlusif lorsqu'il est fixé sur la peau, améliorant ainsi l'hydratation de la surface de la peau et favorisant l'adsorption du médicament. Des indicateurs (28) de modification visibles inclus dans le système constituent des "points de repère" importants de la durée de vie du timbre. Les microcapsules utilisées pour l'indicateur peuvent être formulées de telle manière que la pénétration de l'humidité engendre un changement de couleur au moment où l'ingrédient actif est presque épuisé. Ce changement de couleur avertit l'utilisateur de la nécessité de remplacer le timbre.

Title: Light sensor
Inventor: BIRRELL PETER
IPC: G01J1/42
Filed: 1996-10-28
Abstract: A light  level  sensor  for use  in controlling  the switching of artificial lighting.  The sensor comprises a photoelectric transducer which provides an output signal at a level which is significant of the illumination level of incident light.  An A-D converter and a microprocessor are located in circuit with the transducer for detecting the level of the transducer output signal and for any cyclic  variation  of   the   transducer  output  signal resulting from cyclic variation of the level of incident light.  Further circuit means are provided for generating a sensor output signal if either (a)  the level of the transducer output signal is below a predetermined level or  (b)  the  level  of  the output  signal  is  above  the predetermined  level  and,  at  the  same  time,  cyclic variations occur in the level of the transducer output signal.   When the sensor is used to switch artificial lighting  on,  with  falling  ambient  light,  the  sensor output  signal  is used  to energise a lighting  control relay   when   the   ambient   light   falls   below   the predetermined level.  The relay thereafter is held ON if the sensor detects the presence of a high light level, provided that the high light level is attributable only to the artificial lighting as recognised by detection of cyclic variation of the transducer output signal.

Filed: 1996-12-11
Abstract: This invention pertains to a method for producing high power microwave transmission signals conveying one of a plurality  of  symbols,  wherein  a  symbol  represents  a plurality  of  bits,  and  also  to  a  modulating  array transmitter that operates in accordance with the method. The method includes a first step of applying j bits to a data storage device to address the data storage device to output N bits to N/2 QPSK modulators.  Each of the N/2 QPSK modulators receives a subset (a pair) of the N bits.  Each of the bit pairs specifies one of up to four phase shifts. Within each of the N/2 QPSK modulators, a next step phase modulates a reference (e.g., local oscillator) signal in accordance with a phase shift specified by the received pair of bits.  A next step amplifies the outputs of each of the N/2 QPSK modulators to produce respective amplified QPSK modulated  signals.  A  further  step  combines  the amplified QPSK modulated signals by vector addition to produce one of a plurality of symbols, wherein the produced symbol represents a value of the j  (even number)  input bits.    Also  disclosed  is  a  BPSK embodiment  of  the invention,  wherein there are N BPSK modulators,  each receiving one of the N bits.

Title: Filter with temperature compensated tuning screw
Inventor: LUNDQUIST STEVEN BARTON
IPC: H01P1/208
Filed: 1997-06-02
Abstract: A temperature compensated filter has a compensating screw mounted in a support in the wall of a cavity.  The support is made from a material having a high coefficient of thermal expansion compared to the material of the cavity and the material of the compensating screw.  As temperature changes, the support moves the compensating screw either further into the cavity or further out of the cavity to compensate for the change in resonant frequency of the cavity that would otherwise occur.  The compensating screw can be used with single, dual or triple mode cavities.  The compensating screw can be made of metallic material or it can be made of non-metallic material with a metallic outer surface.  The compensating screw is locked in the support before the support is inserted into the wall of the cavity.  The support is then locked in the wall of the cavity and the screw automatically changes position within the cavity as temperature changes.  An RF barrier can be used to prevent RF energy from the cavity from entering the area of the support.

Title: Blade and motor carrier with height/angle adjustment mechanism
Inventor: PARKS JAMES R
IPC: B23D47/02
Filed: 1997-06-13
Abstract: A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams. The longitudinal movement of the rod compresses the support plate between the work table and a bracket to maintain the position of the support plate with respect to the work table. Also included is an integral arbor wrench which is accessible when the throat plate is removed to lock the arbor to facilitate tool changing. The wrench is designed to not allow reassembling of the throat plate when the wrench is in engagement with the arbor shaft.
