Patent CA-2037142-C (CA)
Title: Logic structure and circuit for fast carry
Inventor: HSIEH HUNG-CHENG
IPC: G06F7/57
Filed: 1991-02-26
Granted: 1996-05-07
Abstract: Programmable logic devices which include multiple blocks of combinatorial function generators and storage elements, and which are interconnected by a programmable interconnect structure are used, among other things for performing arithmetic functions which use logic for generating the carry function.  When a large number of bits is to be processed, the carry function typically causes significant delay or requires significant additional components to achieve a result at high speed.  The present invention provides dedicated hardware within the logic blocks for performing the carry function quickly and with a minimum number of components.  The invention takes advantage of the fact that a carry signal to be added to two bits can be propagated to the next more significant bit when the two binary bits to be added are unequal, and that one of the bits can serve as the carry signal when the bits are equal.

Title: Method of manufacturing thermoplastic sheet of film
Inventor: GROSS HEINZ
IPC: B29C48/305
Filed: 1991-06-07
Granted: 2001-04-24
Abstract: An extruded, smooth finished solid sheet or film of thickness < 1 mm is prepared from a thermoplastic plastic having a glass transition temperature > 50°C, by extruding the plastic in the thermoplastic state through a slot nozzle to form a flat extruded strip, which is introduced into the roll gap of a roll stack having a smoothed upper roll and a lower roll, with the upper roll being maintained at a temperature below the glass transition temperature of the thermoplastic plastic and with the lower roll being maintained at a temperature in the plastic state domain of the thermoplastic plastic, and, after exiting the roll gap, the extruded strip is moved resting on a smooth-finished endless belt which passes around the lower roll, thereby smoothing the surfaces of the strip; and cooling said extruded strip below the glass transition temperature.

Title: Vehicle suspension system
Inventor: BIANCHI MAURO
IPC: B60G17/02
Filed: 1990-10-05
Granted: 2001-03-13
Abstract: The invention relates to a suspension with dynamically variable flexibility or stiffness. The suspension method utilizes one or a plurality of elastic elements mounted opposite to each other so as to impart to the vehicle suspension a variation of stiffness or flexibility with two slopes on the curve (shock-expansion and compression effort) and said utilization of different stiffnesses or flexibilities is localized during the spring movement of the suspension at the vicinity of the position of the loaded vehicle on wheels and the lowest stiffness is situated on the second part of the crushing stroke of the wheel suspension. The invention applies to suspensions particularly for motor vehicles.

Title: Fluidized bed reactor with protected fluid distributor
Inventor: ENGSTROEM FOLKE
IPC: B01J8/24
Filed: 1990-03-26
Granted: 1993-06-08
Abstract: A fluidized bed reactor uses fluid conduits for supplying fluids (such as liquid, gaseous, or fine solid material in suspension fuels), into a reactor chamber. The fluid conduits extend horizontally from, and substantially perpendicularly to, a side wall into the reactor chamber.

An upright partition, preferably of refractory material, covers the fluid conduits.
Patent CA-2052202-C (CA)
Title: Method and apparatus for oil well stimulation
Inventor: NENNIGER JOHN
IPC: E21B36/04
Filed: 1991-09-25
Granted: 1995-10-10
Abstract: This  invention describes  a method  of  stimulating production from an oil well by removing solid wax deposits from a production zone.  An electrical resistance heater comprised of a packed bed of spherical heating elements is lowered through the tubing on a wireline and placed adjacent to the perforations. Solvent is pumped through the heater to raise its temperature by 200 °C and then into the formation to contact wax deposits. The solid wax deposits are liquified and together with the oil and the solvent form a single liquid phase.  The wax is then removed from the formation by placing the well back on production. Because the invention completely avoids the use of either water or gas,  the saturation of the water and gas phases in the formation is minimized, thereby maximizing the mobility of the liquid phase containing the wax and facilitating the removal of the  liquified  wax  from  the  treatment  area  before  it reprecipitates.  The packed bed heater has a large surface area and a large heat transfer coefficient, so high power rates (150 kw) can be achieved within a compact volume (6m long x 5cm id) without solvent degradation.  By heating the solvent to a high temperature, a minimum volume of solvent is required, thereby minimizing production downtime and solvent costs. The burnout and catastrophic failure problem usually associated with resistive heaters is avoided due to the multiplicity of current paths through the packed bed.
