Patent CA-2026021-A1 (CA)
IPC: H03M13/33
Filed: 1990-09-24
Abstract: Synchronization conditions of a Viterbi decoder are detected using the differences between minimum branch metrics and corresponding minimum path metrics.  In accordance with the invention, zero differences are monitored, non-zero differences are monitored and weighted, and the monitoring is used to detect in-synchronization or out-of-synchronization condition of the decoder.  More particularly, the differences are non-linearly mapped (F3) into a value in a first set for some differences or a value in a second set for the other differences.  The sign of a value in the first set is different from all of the signs of the values in the second set.  In one embodiment, the first set includes a single value of unity, whereas the second set includes a value corresponding to the difference.  In accordance with the method of synchronization detection, an accumulator, counter or indicator is initialized (F1) to an initial value and as the mapped values are produced in sequence, they are sequentially summed (F5) with the value of the accumulator, counter or indicator so as to continually update the sum. The value of the accumulator, counter or indicator is compared to an out-of-synchronization threshold and to an in-synchronization threshold (F6, F7).  Each time the value of the counter, accumulator or indicator reaches or exceeds the value of the out-of-synchronization threshold, an out-of-synchronization status is declared (F9) and the counter, accumulator or indicator is returned to its initialized value, and the process continues.  On the other hand, if the value of the accumulator, counter or indicator drops below the in-synchronization threshold, then an in-synchronization status is declared (F8) and the value of the counter, accumulator or indicator is clamped so that it cannot drop any further below the in-synchronization threshold.

Patent CA-2026705-A1 (CA)
Inventor: BARGER DENNIS D
IPC: B29C63/00
Filed: 1990-10-02
Abstract: Covering a rigid or hard but pliable, smooth surface with a multilayer masking film having a smooth side and an embossed side is disclosed. The smooth side of the masking film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the masking film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when a drop of water is placed between two sheets of glass. The embossed side of the masking film forms microscopic air pockets when rolled upon itself which prevents blocking. This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.

Title: Dispensing cabinet for strip material
Inventor: BIGGAR R WARREN
IPC: A47K10/36
Filed: 1990-10-15
Abstract: ABSTRACT OF THE DISCLOSURE          A dispensing cabinet for strip material, such as paper towel, has a relatively large handwheel extending through a slot in the front face.  A roll of the material is engaged by a boss member on the wheel so as to be rotated by rotation of the handwheel.  The edge of the handwheel is provided with radially-extending protrusions constituting both finger engaging members to help the user rotate the handwheel and ratchet teeth engageable by a ratchet member mounted on a pivoted plate mounted adjacent the horizontal cabinet slot through which the strip is dispensed.  The ratchet member is normally clear of the ratchet teeth, but any attempt to pull the strip from the roll engages the ratchet member with a tooth so that the roll cannot rotate; the strip can therefore only be dispensed by operation of the handwheel, reducing the tendency to dispense a wastefully long strip.  The dispensed portion is torn from the remainder of the roll by pulling it strongly against the lower edge of the plate, which also engages the ratchet so that the roll cannot rotate during the tearing operation.

Title: Enhanced oil recovery for oil reservoir underlain by water
Inventor: PEBDANI FARROKH N
IPC: E21B43/243
Filed: 1990-10-25
Abstract: ABSTRACT    --A method for recovering viscous oil from a subterranean, viscous oil-containing formation underlain by a water zone.          Steam is injected into the formation via the injection well at the oil/water contact and oil is recovered from the formation until steam breakthrough occurs at the production well thereby forming a hot plate at the oil/water contact.  Thereafter, the production well is shut-in and a combustion-supporting gas, preferably pure oxygen, is injected into the formation at the oil/water contact causing an in-situ combustion reaction to occu at the oil/water contact and pressurization of the formation.          Injection of the combustion-supporting gas is continued until th formation is pressurized to a specific pressure not to exceed th pressure at which fracture of the overburden above the formation would occur.  Thereafter, the injection well is shut-in and oil is recovered from the formation via the production well.  If desired, after injection of the combustion-supporting gas is discontinued, the formation may be subjected to a soak period by shutting-in the injection and production wells for a time sufficient to allow the injected combustion-supporting gas to be consumed in the in-situ combustion reaction.

Title: Chiller unit end plate boom device
Inventor: WARD GARY
IPC: B66C23/18
Filed: 1991-08-26
Abstract: ABSTRACT   In industrial refrigeration units as used in malls and office buildings for air conditioning, there is a main component called the "Chiller Unit". The Chiller Unit is very basically a liquid to liquid inter-cooler comprised of a large steel box with tubes running the length of it. These tubes require periodic maintenance which involves removal of large end plates which weigh approximately 500 lbs. These plates are bolted to the ends of the chiller unit.            Until this time, the plates have been removed by two methods. One method requires using a blocks and tackle, rope or chain, the nearest roof beam or member, and at least two men. The other method involves pieces of rope or chain, and three to four men to manually lift the plate.   In this invention, a crane like device called a "Chiller Unit End Plate Boom Device" mounts to the Chiller Unit and to the Chiller Unit End Plate and, via a chain, cable, block and tackle or come along, suspends and holds the end plate. Once the End Plate is unbolted, the device's "Boom" rotates in its base to effectively swivel the End Plate out of the way so that maintenance can be carried out. Replacement of the end plate is simply a reverse of these procedures. All of these procedures can be safely and quickly carried out by one man.

Abstract: A novel cell culture device for the production of metabolites as provided herein. The device includes a housing, and a cell culture space, within the housing.      Fresh nutrient medium inlet means and outlet means, are connected, in parallel, to a sheet of tubes forming a wall of the culture apace and which are in fluid communication with the culture space. At least a subset of open-ended permeable capillaries is arranged in a layer within the culture space. The open ends of the capillaries lead to external inlet gas means and to outlet gas means and are in gaseous communication with the interior of the capillaries. The capillaries are arranged at equal intervals so as to form, on one side of the sheet of tubes, one subset allowing a homogeneous distribution for gas exchanges with the cells. A spent medium outlet means is connected to a first micron sieve forming each downstream wall of the cell culture space, in order to ensure that the cells are confined while allowing said spent medium to leave. The sheet of tubes in connection with the fresh nutrient medium inlet means and the outlet means, are structured in a closed-loop circuit. The sheet of tubes is constructed so as to provide, when fresh nutrient medium is passing through the circuit, simultaneously a first flow of fresh medium through each of the tubes, from end to end, and a second flow of fresh medium which is perpendicular to the first flow, from the tubes to the cell culture space, through their permeable walls.
