Abstract: A firefighter's coat which has sleeve portions which cover the wrists of a firefighter who wears the coat. Each sleeve portion has an edge part: adjacent a hand of the firefighter. A strip of flexible material is connected to the edge part of the sleeve portion.      The strip of flexible material is adapted to be posi-tioned between two digits of the hand of the firefighter, such as between the thumb and the adjacent finger of the hand of the firefighter. Thus, the sleeve portion is maintained in covering relationship upon the wrist of the firefighter, even while the arms and hands of the firefighter are actively moved in a firefighting operation.

Title: Methods and apparatus for transparent tone-in-band transmitter, receiver and system processing
Inventor: BATEMAN ANDREW
IPC: H04B1/10
Filed: 1990-03-23
Granted: 2000-03-28
Abstract: In deriving a control signal for recombining the parts of the spectrum separated by a frequency notch in transparent tone-in-band signals, cross-correlation products give rise to undesirable frequency and phase fitter. In a receiver which overcomes this problem an input signal E containing the notch is passed to two first mixers and then portions corresponding to the lower and upper portions of the input spectrum are selected by two mirror filters before being translated in frequency by two second mixers to a final output band in which the notch is eliminated. Two selection filters select parts of the spectra at the outputs of the first mixers which correspond to an overlap region of the said lower and upper portions when derived in a transmitter and apply them to a control-signal mixer. A control signal for the second mixers is derived from the output of the control-signal mixer by noise filtering and frequency division by two. The above mentioned problem is overcome by giving the mirror filters transfer functions H1-(f) and H1+(f) which are the same as the transfer functions of mirror filters in the transmitter which produced the notch and by giving the selection filters transfer functions H2-(f) and H2+(f) which satisfy the relationships H2-(f) = ~H1+(f)2 and H2+(f) = ~H1-(f)2.

Patent CA-2027248-C (CA)
Title: Multiple compartmented dynamoelectric machine
Inventor: KING JAMES L
IPC: H02K11/00
Filed: 1990-10-10
Granted: 1995-09-05
Abstract: A motor includes a round steel frame with a stator unit fixedly mounted therein and spaced from the frame ends.  Spaced bearing frames are secured within the round frame and support a rotor unit within the stator unit and in the bearing frames.  One or both bearing frames are spaced from the round frame ends, and define corresponding auxiliary compartments.  In a motor pump unit, an end plate closes one end and defines a control compartment.  The pump housing closes the opposite end and forms a fan and drip compartment within the round frame.  The round frame has openings in the drip compartment to by-pass pump water leakage from the motor compartment.  A fan in the fan compartment provides motor cooling.  Motor controls such as power connectors, a centrifugal start switch unit, electronic timers, and the like are mounted within the control compartment to form a self-contained motor.  The motor compartment and various auxiliary compartments can be formed within the frame by appropriate securing of the bearing frames and internal walls in the round frame.  Thus, two and three compartment motors are formed with one or more internal wall structures secured directly to the round tubular motor frame.

Title: Switching power supply for microwave oven
Inventor: FUJISHIMA KUNIHIRO
IPC: H05B6/68
Filed: 1990-11-02
Granted: 1993-01-05
Abstract: Abstract of Disclosure The present invention relates to a switching power suplly for microwave oven in which a DC power is changed to a pulse by means of a switching element coupled to a primary winding of  an  inverter  transformer  to  supply  the  power  to  a  high frequency oscillator  (hereinafter referred to as a magnetron) coupled to a secondary winding.   A reference voltage is set lower  than  an  ordinary  state  from  the  time  of  turning  on until the oscillation of  the magnetron starts.   Accordingly, a power   supplied from the secondary winding of the inverter transformer  to  the  magnetron  is  set  low.  The  reference voltage  increases  when  the  oscillation  of  magnetron  starts, and  the  same  also  returns  to  the  ordinary  state  when  the oscillation returns to the ordinary state.

Title: Method of filling and sealing a deformable container
Inventor: BALCOMBE ROY
IPC: B65B31/02
Filed: 1991-03-15
Granted: 1997-04-01
Abstract: A method of filling and sealing a bi-stable container, subjected to a gaseous environment, with a product, and a container containing the product.  The container has a bi-stable, unribbed bottom having a hoop member surrounding the side edges of the container and movable between a first position, in which the container bottom is moved into a stable downwardly extended position, and a second position, in which the container bottom is moved into a stable inverted domed configuration.  The container bottom is placed in its stable downwardly extended position and the product is charged into the container to a level having a volume less than the container volume but equal to the filled volume with such level defining a headspace opening.  The container is then placed in a vacuum environment chamber.  A generally flat lid is sealed to the container and the vacuum environment is removed from the container so as to return the container to atmospheric  pressure.    Hoop  stress  of  the  hoop  member overcomes the bending stress around said unribbed bottom such that the unribbed bottom of the container is inverted into said stable inverted domed configuration thereby forcing the product  into  close  contact  with  the  lid  to  reduce  the headspace between the product and the lid, the lid remaining in its generally flat configuration.

IPC: H04N1/411
Filed: 1991-03-26
Granted: 1994-10-25
Abstract: IMPROVED DATA DECOMPRESSION SYSTEM AND METHOD        ABSTRACT Data decompression of an image is implemented by reconstructing blocks of pixels from a table that stores orthogonal icons and related attributes representing a data compressed image. Each block of pixels is processed independently of all other blocks. Orthogonal processing is employed to reconstruct orthogonal features that relate to manufactured elements in an image. An optimum set of orthogonal icons and an optimum set of attributes for each icon are employed to further improve data decompression and fidelity. The optimal set of orthogonal icons includes a flat icon, an edge icon, a ribbon icon, a corner icon and a spot icon. The optimal set of at-tributes includes average intensities, intensity transition position and separation, and angle of the principal axis.

Granted: 1994-03-08
Abstract: Abstract An adapter that releasably engages the rim of an aluminum beverage can and which provides a bottle-like spout so that a consumer may drink from the can as if drinking from a bottle.          In  a first embodiment, a flexible base has radially inwardly extending  lugs that releasably  engage the rim of the can at circumferentially  spaced  locations  thereabout.  A  concave plate  having  a central,   oval shaped  opening  is  fixedly secured  about  its  periphery  to  inner side  walls  of the adapter, in vertically spaced relation to the open bottom end of the adapter.  A resilient gasket circumscribes and depends from  the opening  and the vertical  extent of  the gasket is such  that the bottom edge of the gasket is coplanar with the bottom of the adapter so that the gasket tightly seals a pour opening  punched  in the lid of the can when  the adapter is detachably  secured  to  the  rim  of the can.  In  a  second embodiment,  the plate, opening and gasket are eliminated and an  annular ring  having  a pointed lower  edge provides  the needed seal.
