Patent CA-2002264-A1 (CA)
IPC: G06F11/34
Filed: 1989-11-06
Abstract: Abstract of the Disclosure:     In an information processing device for use in indicating an operation number of floating point operation elements, such as either vector elements of each vector instruction or scalar instructions, the floating point operation elements are successively counted by an adder and a register to produce operation number signals representative of results of the counting.  The operation number signals are periodically read out of the register as preceding and following operation number signals at preceding and following ones of periodical signals sent as a time signal from a digital timer, respectively, and are held in registers.          A subtracter subtracts the preceding operation number from the following operation number to calculate a difference signal between the preceding and the following operation numbers and to provide the operation number per unit time.  The difference signal is visually displayed on a display unit in real time.          Alternatively, each of the preceding and the following operation number signals may be memorized in a scalar register together with the time signal.

Title: System and method for controlling the angular position of a shaft and tension and draw control system for a printing press
Inventor: MOERSFELDER BRADLY S
IPC: B41F13/02
Filed: 1990-01-16
Abstract: ABSTRACT         A system for controlling draw on a moving web, and in particular, a system for maintaining a constant tension in a moving web to control the link of web moving past a cyclicly operating apparatus in a printing press by controlling the angular position of an upstream roll relative to the angular position of the printing units.  By maintaining a constant tension, one webs exiting the two rollers of a printing press, link variations are controlled and lengthwise registra-tion between respective webs is maintained.  The tension of the web is sensed, and the angular position (as opposed to angular velocity) of the two roll is con-trolled in accordance with the sensed tension.  A system for controlling the angular position of a shaft employing phase lock group techniques is also disclosed.  A single indicative of the actual angular position of the shaft is generated by phase shifting a signal from a reference signal by an amount proportional to the angular position of the shaft.  A signal of predetermined phase with respect to the reference signal is generated to indicate the desired position of the shaft.  By deviation in phase of the phase shifted signal from the desired position signal is then employed to develop a control signal to effect adjustment of the angular position of the shaft.  The signal indicative of the angular position of the shaft may be generated by generating a magnetic field in accordance with the reference signal, and rotating a coil in the magnetic field in correspondence to the rotation of the shaft.  A control signal in which a single knob is utilized to control a large number of parameters is also disclosed.

Title: Apparatus for dispensing a substance onto a crop material at a controlled rate

Filed: 1990-02-21
Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for dispensing a preservative or other substance, in solid or liquid form, onto a crop material being baled, the substance being dispensed onto the crop material before it is baled at a rate which is dependent on the moisture content of the crop material and the bulk rate of flow of crop material through the baler.  The apparatus, which may be mounted on a square baler or a round baler, includes a first sensor for sensing the moisture content of the crop material and producing a first signal, a second sensor for producing an output signal indicative of the bulk rate of crop flow through the baler, and a control circuit responsive to the first signal and the second signal for producing a pulse width modulated signal for controlling the speed of a motor.  The motor controls the rate at which the substance is dispensed from a container onto the crop material.

Abstract: ABSTRACT OF THE DISCLOSURE           The connector of this invention has a connector housing  with  a  terminal  accommodating  chamber  formed therein, into which a female terminal is to be assembled. A release bar is formed separately from the connector housing. With the release bar mounted on the connector housing, the female terminal is inserted into the connector.   As the female  terminal  advances  in  the  terminal  accommodating chamber, its front end abuts against and then slides along the tapered surface of the front portion of the release bar, forcing it up.  At the same time the female terminal slides over a lance formed in the connector housing.  As it further advances, the front end of the lance engages with a hole in the underside of the female terminal and the front portion of the release bar snaps into an opening formed in the upper side of the female terminal.  The female terminal in this way is doubly locked by the lance and by the front end of the release bar.  If the lance fails to fit into the hole of the female terminal, the front  portion of the release bar rests on the female terminal, projecting markedly from the housing, which is easily recognizable from outside.  This in turn alerts the assembly worker to the incorrect mounting.

Abstract: ABSTRACT      A method is disclosed for using a pair of tracers to determine the in-situ residual oil saturation surrounding a single wellbore in subterranean reservoirs.  The first tracer has a labile hydrogen atom, and the second tracer is formed by substitution of a hydrogen isotope, i.e., tritium or deuterium, for this labile hydrogen atom.  The mixture comprising the tracer and its isotopic form is injected into the reservoir where the isotope exchanges with non-isotopic hydrogen from the reservoir water.  The produced sample is analyzed for the presence of both tracers, and the residual oil saturation is calculated.

IPC: H04L25/06
Filed: 1990-10-12
Abstract: A controllable amplifier, which has two symmetrical outputs, at which two output signals mirror-symmetrical with respect to each other are present, is used for amplification of a burst signal. To achieve the largest possible eye opening of the signals to be fed to a comparator, a predetermined d.c. voltage difference for the formation of matched signals is adjusted for both output signals. After this, the arithmetic mean values of the two matched signals are formed and are fed to a second comparator. The output value of the second comparator is fed to an integrator, to which a reference voltage is also fed. In case of a deviation of the mean values of the two matched signals from each other, the amplifier is adjusted in a compensating direction by the integrator.

Filed: 1990-11-21
Abstract: A flexible glass fiber reinforcement material has a microwave-sensitive or ultraviolet sensitive binder added and is formed into a desired shape.  Selected electromagnetic energy (microwave or ultraviolet) is then applied to cure and rigidize the binder.  A mold for shaping the reinforcement material comprises a mold cavity defined by microwave or ultraviolet transparent material divided into separate and separable mold parts and, for microwave applications, each part carries one half of a split microwave waveguide which directs microwave energy to cure the binder resin when the mold is closed.  For ultraviolet applications, an ultraviolet source (or sources) is located in the mold.  Energetic stitching of a reinforcement rib is performed by applying a binder resin to the  rib at at least one location, placing that location into contact with a preform and curing the binder resin to bond the parts together.
