Title: Chlorine-free organosolv pulps
Inventor: CRONLUND MALCOLM
IPC: D21C9/153
Filed: 1995-11-21
Abstract: This   invention   provides   for  a  batch  and continuous  process   with   countercurrent   recycle   of bleaching  filtrates for the delignification and bleaching of pulp.  Oxygen delignification of pulp  is  achieved in excess of from about 50% to about 76% as measured by kappa numbers, while the pulp viscosity is  minimally  decreased in the range of from about 2 to about 5 cps.  Bleaching of delignified pulp is achieved  with  peroxy  compounds  and ozone  and  pulp brightness of from about 82 to 88 ISO can be achieved with  pulp  containing  zero  level  TOX  from chlorine  based  bleaching chemicals and zero level of AOX in the bleach effluents.  Higher brightness of from  about to  about  92  ISO can also be achieved by addition of very low levels of  chlorine  based  bleaching  chemicals. Corresponding  bleach  effluents contain less than 200 ppm AOX.  Bleaching filtrates can be recycled for pulp washing and  for  use  with  an  organosolv  pulping process which results in significant energy savings  and  mitigation  if not  elimination  of  pollution  typically associated with chlorine based bleaching.  This invention also relates  to bleach  pulp  product  derived  from the process and to an apparatus for carrying out the process.

Patent CA-2172468-A1 (CA)
Title: Agricultural Sweep and Mounting
Inventor: BUCHER DAVID HOFFER
IPC: A01B35/22
Filed: 1996-03-22
Abstract: Knock-on sweep mounting structure includes a combination of first and second tapers, and mating notch structure in the sweep connecting portion and in the mounting structure on the shank, to provide easy installation and prevent sweep loss. The notch structure facilitates easy connection of the sweep on the mounting structure by rotational movement of the sweep at a single narrowed attaching location between the tapers. Once on the mounting structure, the sweep can slide along the shank. By forcing the sweep upwardly, the sweep is wedge-locked in the field-working position on the first taper.  The second taper, opposite in direction from the first taper, fits against the naturally occurring shape of the bottom of the sweep connecting portion to retain the sweep on the shank if the sweep is dislodged from the first taper.  The combination of tapers with the notch structure located therebetween substantially reduces the possibility of a sweep accidentally falling off the shank.

Patent CA-2176459-A1 (CA)
Inventor: HEDBERG MATS OLOF JOAKIM
IPC: H03K19/0175
Filed: 1994-12-01
Abstract: The invention relates to a signalling system which is adapted for digital signals and which includes a signal transmitter, a signal receiver and a connection which connects the transmitter to the receiver.  The transmitter includes an output buffer which has at least one transistor connected to the lowest level of a signal supply voltage, such as "O" potential or earth potential.  Driving or steering of the transistor in response to a received control signal causes the transistor to switch from a state of high impedance to a state of low impedance which exhibits resistive or at least predominantly resistive properties, such as to form an information-carrying output signal.  A first of two series-connected transistors is connected to the lowest level of the signal supply voltage, for instance "O" or earth potential, whereas the other transistor is connected to the signal supply voltage.  A connection conductor on which the information-carrying signal is transmitted is connected between the transistors.  The transistors are brought to different states simultaneously, and in a state of low-impedance, the impedance value shall correspond to the impedance value (the resistance value) of the connection.

IPC: B60R13/07
Filed: 1996-05-23
Abstract: A liner for a vehicle is provided between the vehicle's floor and frame and protects the underside of the floor from moisture coming from underneath the vehicle. The liner also has a drainage feature which allows for liquids trapped between it and the floor to drain therethrough. The vehicle liner is made up of a pair of strips of a waterproof material disposed adjacent to each other with a gap provided between them and a third strip of a waterproof material covering the gap. The three strips effectively remove liquids from underneath the vehicle floor and yet form a moisture barrier for preventing moisture arising from underneath the vehicle from contacting with the vehicle floor.

Title: Codebook gain attenuation during frame erasures
Inventor: SHOHAM YAIR
IPC: G10L19/00
Filed: 1996-05-27
Abstract: A codebook-based speech decoder which fails to receive reliably at least a portion of a current frame of compressed speech information uses a codebook gain which is an attenuated version of a gain from a previous frame of speech. The speech decoderincludes a codebook memory and a signal amplifier. The memory and amplifier are used in generating a decoded speech signal based on compressed speech information. The compressed speech infomation includes a scale-factor for use by the amplifier in scaling a codebook vector. When a frame erasure occurs, a scale-factor corresponding to a previous frame of speech is attenuated and the attenuated scale factor is used to amplify the codebook vector corresponding to the current erased frame of speech.

The clamp head is moved on the shaft until the horizontally extending upper shoulder rests on a top edge of the crown molding while the vertically extending bearing surface engages a side edge of the crown molding in alignment with the worktable fence.
Patent CA-2179786-A1 (CA)
Inventor: ACKLAND BRYAN DAVID
IPC: G11C11/419
Filed: 1996-06-24
Abstract: A memory sense amplifier for a static random access memory includes a pair of transistor amplifiers respective to the bit lines threading the memory. The power consumed is minimized without sacrificing speed of operation by temporarily connecting the source electrodes of the transistor amplifiers to the bit lines to allow them to track the states of the bit lines before a current path is completed to the drains of the transistors to allow them to draw current from the bit lines, thereby minimizing the time that the sense amplifiers are permitted to draw current from the bit lines. In addition, an economy of circuitry is achieved by eliminating the need for a separate latch circuit by disconnecting the sense amplifiers from the bit lines and thereafter enabling them to latch the information state read from the bit lines. The memory cycle is defined in four distinct phases ("PRECHARGE", "SENSE", "SELECT", and "HOLD"), instead of in two phases ("clock" and "select") followed by indeterminate length self-timed intervals as provided in prior art US patent 5,309,395.
Patent CA-2183176-A1 (CA)
Inventor: PELLY BRIAN R
IPC: H02H7/16
Filed: 1996-08-12
Abstract: A high power DC blocking device is provided which blocks DC current, passes AC current, and limits the voltage across it under fault conditions. A DC blocking capacitor is used to block the flow of DC current, while allowing the passage of normal AC currents. A main bypass path includes switching devices which provide a low impedance path across the capacitor under fault conditions. Auxiliary switching devices are used to connect a storage capacitor across the device at the initiation of a fault, thereby charging the storage capacitor to a stored voltage level before the main switching devices are fired. After the fault passes, the auxiliary switching devices are fired once again to apply the stored voltage in the storage capacitor to the main switching devices to commutate them off. The storage capacitor and auxiliary switching devices also form part of a voltage clamp circuit which dissipates inductive energy stored in a system to which the DC blocking device is connected. Multiple backup firing circuits are provided which activate the low impedance bypass path in the event of failure of the main firing circuits or of the blocking device control system. The effectiveness of the DC blocking device is continuously monitored using a DC current sensing circuit which is capable of distinguishing small DC currents in the presence of large AC currents.
