Patent CA-2064506-A1 (CA)
Inventor: NOGUES MICHEL
IPC: C23C2/32
Filed: 1992-03-31
Abstract: Pickling or galvanising process according to which high-frequency vibrations are imparted to the sheet metal (1) travelling through an acid-filled trough; the device comprises at least one pair of electromagnets (2,3) arranged facing each other on both sides of the sheet metal (1), which are supplied with currents of the same frequency and each exerting a periodical attraction force on the sheet metal (1), the forces exerted by each electromagnet (2,3) being offset by  pi /2, with the result that the sheet metal (1) vibrates at a frequency which is twice that of the supply current. The vibratory power injected into the sheet metal is greater than the cavitation threshold of the reactive solution in the vicinity of the sheet metal, with the result that this cavitation and the vibrations imparted to the sheet produce fissures in the layer of scale and make it easier to attack with acid, which considerably shortens the time needed for pickling the sheet metal. <IMAGE>

Abstract: ABSTRACT                     METHOD AND APPARATUS FOR PERFORMING PATTERN SEARCH FUNCTIONS            A method and apparatus for searching a pattern such as an address pattern of 48 bits among a list of addresses of 48 bits  which  can be  dynamically updated.   A  search table comprising control blocks is used for conducting the search of a specified pattern by processing logic circuits.   The control blocks can be of a first type indicative of test operations on at  least one  selected bit of the to- be-searched pattern and of of a  second type indicative of compare operations with a specified value and of a third type indicative that no operations have to be performed. These control blocks are chained in at least one chain in such  a  way that  each  control  block  chain  determine operations which  lead  to  the  finding  of  one  of  the p patterns. To perform the search, a processing logic circuit reads a first control block at a search table address which is derived from a selected field of k=12 bits of the pattern to be searched.  It generates a not-found pattern signal if the read control block is of the third type, or executes the the operations indicated in the first read control block and the control blocks chained thereto, until a control block of the  second  type  is  is  reached  and  compares  the  to  be searched pattern with the specified value in the control block of the second type.  If a mismatch is detected,  it generates a "not found pattern" information and if a match is detected it generates a a "found pattern" information.

Abstract: Abstract of  the Disclosure A non-interference method of determining the frequency characteristics of a cable television (CATV) system adds an RF test pulse to an RF video signal in the vertical interval between equalizer pulses.

RF pulses of different frequencies within each channel of the CATV system are used to determine the frequency characteristics of each channel.

Abstract: An apparatus for measuring fluid flow rate and cardiac output comprises a support member (12, 32) having a distal end (14, 34), a proximal end (16, 36) and an outer wall (18, 38). A first temperature sensing means (20, 44) is positioned on said outer wall (18, 38) with a second temperature sensing means (22, 46) positioned on said outer wall (18, 38) proximal to said first temperature sensing means (20, 44). Heating means (24, 26, 48) is also positioned on said outer wall (18, 38) juxtaposed to said first temperature sensing means (20, 44). Thus, by energising the heating means (24, 26, 48) a temperature differential between the first and second temperature sensing means (20, 22, 44, 46) is established.  The energy required to maintain the temperature differential can be controlled and monitored, and correlated to fluid flow rate and cardiac output.

Title: Modulation frequency control in a fiber optic rotation sensor
Inventor: FERRAR CARL M
IPC: G01C19/72
Filed: 1991-05-24
Abstract: In a fiber optic rotation sensor having a pair of light waves counter-propagating in an optical waveguide loop, a phase modulator is driven by a modulating signal at the loop eigenfrequency. Upon exiting the loop the waves are combined into a light intensity signal which is sensed, the sensed signal including a component in quadrature with a desired rotation rate component, the magnitude of the quadrature component being proportional to any deviations in the frequency of the modulating signal from the loop eigenfrequency. The phase modulator is servo-controlled so as to drive the quadrature component to zero, thereby compensating for any deviations in the modulator frequency from the loop eigenfrequency.

Title: Eddy current drive and motor control system for oil well pumping
Inventor: WOLCOTT JOHN H
IPC: F04B49/06
Filed: 1993-03-16
Abstract: An eddy current coupling with an electrically controllable field current is used to rotatably connect a drive motor to an oil well pumping mechanism where the eddy current drive speed is controlled to a reference speed using a speed feedback control system and operation can be limited in torque output by a torque feedback control system. in a first alternative embodiment, the eddy current coupling output speed is controlled by a stroke modulation unit using a first selected speed for the upward pumping stroke and a second selected speed for the downward pumping stroke. In a second alternative embodiment a controller is used to select torque or speed control for the upward or downward pumping stroke. An eddy current coupling output stall condition is sensed by comparing the eddy current drive speed to a preselected stall speed and when the eddy current coupling output speed dips below the stall speed limit, the eddy current coupling coil electrical power is disconnected thereby terminating the electromagnetic coupling of the eddy current inductor and pole member to disconnect the drive motor from the oil well pumping mechanism.
