Title: Doppler blood flow system and method using low frequency noise signal processing
Inventor: WEAVER BILLY L
IPC: G01P5/24
Filed: 1990-01-04
Abstract: ABSTRACT OF THE DISCLOSURE           A Doppler blood flow system and method in which an ultrasonic wave is reflected off of red blood cells in blood flowing in tubing. The relfected ultrasonic wave is digitally processed in the frequency domain. The flow rate of the blood is directly related to the average frequency of the Doppler signal. The typical Doppler signal is not a single frequency representing a single flow rate but is really an entire range of frequencies in which certain frequencies predominate which are indicated by increased amplitude of the signal when plotted in the frequency domain. The typical Doppler signal may actually have two "humps", one at a higher frequency which represents the actual information bearing content of the signal related to flow rate and one at a lower frequency which is caused by vibrations in the blood tubing system itself and could be caused by motor noise from the blood pump. Since the flow rate is related to average frequency of the information bearing portion of the typical Doppler signal, the low frequency "hump" must be taken out of Doppler signal in order to obtain an accurate flow rate.

Abstract: The present invention is directed to a suspension mechanism (10, 310, 410, 510 and 610) utilized to interconnect the seating portion (16) as well as the back supporting portion (18) of a chair assembly (12, 312, 412, 512 or 612) to a pedestal assembly (14). A support means (30, 430 or 530) is fastened to the upper end portion of the pedestal assembly (14). A connecting means, in the form of a primal seat spring (40), or a rigid, connecting plate (513), is secured to the support means (30, 430 or 530) and extends generally upwardly and rearwardly therefrom to be secured to the underside of a seating portion (16). An interactive spring (60 or 660) may also be secured to the support means (30, 430 or 530). The interactive spring (60 or 660) extends outwardly from the support means (30, 430 or 530) in generally parallel relation with the connecting means (40 or 513) to he disposed in a cantilevered fashion therebetween. The back supporting portion (18) may include a back cushion assembly (102) that is structurally carried by a stanchion (90, 390, 490, 490 or 690) that may be fixedly, or pivotally, secured to the seating assembly (16). When the stanchion (90, 390, 590 or 690) is pivotally mounted, a follower (130) may be presented from the stanchion (90, 390, 590 or 690) operatively to engage the interactive spring (60 or 660). A main back spring (140) may also be secured to the stanchion (90 or 590) to interact against the undersurface (146) on the seating pan (72) of the seating portion (16). One or more lock-out assemblies (150) may be utilized to effect immobilization of the back supporting portion (18) with the seating portion (16) and/or the seating portion (16) with respect to the pedestal assembly (14) if those components are not permanently affixed to each other or are not manually adjustable with respect to each other.
Patent CA-2017735-A1 (CA)
Inventor: PRODAN MARINO
IPC: E05D11/10
Filed: 1990-05-29
Abstract: ABSTRACT   The invention relates to a furniture hinge, particularly a cup-hinge, which comprises a stationary box-section hinge arm adjustably fastened to a base plate, a swingable hinge cup, a pair of connecting pivot levers which pivotably connect the cup and the arm and a spring assembly located within the box-section hinge arm.  Between a control cam of the inner pivot lever and a disc-shaped insert of a pressure spring of the spring assembly there is inserted a transmission pin, which is held and guided by slots that are arranged in the side walls of a housing for the spring assembly and are inclined with respect to the axis of symmetry of the spring.  When opening the furniture door, the inner hinge lever and thereby the control cam are swung around a hinge dowel connecting the inner hinge lever and the hinge arm. Thereby, a snapping section of the control cam pushes the transmission pin guided in the inclined slots of the spring housing, which results in the compression of the spring.  On opening the door further, the snapping section of the control cam is followed by a sliding section, which is defined by a circle, whose centre coincides with the hinge dowel of the inner hinge lever. Thus, on the further opening of the door wing the pin slides along the sliding section of the control cam, which makes possible a soft and even opening of the door up to the end position when the door is fully open.  When closing the furniture door, the hinge lever and thereby the control cam evenly moves in the opposite direction until the sliding pin moving along the sliding section of the control cam reaches the snapping section thereof.  The pin inserted in the inclined slots of the housing, aided by the spring force loading it, begins to push away the control cam and thereby also the inner hinge lever. The moment of rotation generated thereby makes it possible to keep the door in its closed position.

Title: Method for generating coarse precipitates from solutions or slurries containing acids or metal salts
Inventor: SHIBLEY PAUL W M
IPC: C02F1/56
Filed: 1990-09-12
Abstract: Abstract of the Disclosure A method is proposed which enables the formation of coarse, high density precipitates when treating solutions or slurries containing acids or metal salts.  This is done by flocculating a slurried precipitant, such as hydrated lime, and adding such flocculated precipitant to the solution or slurry to be treated while agitating the same.          During this reaction, the floccules of the flocculated precipitant become coated or encapsulated with precipitate which is broken under agitation to form the coarse particles of precipitate while uncovering the floccules of the precipitant to allow continuation of the reaction.          Once formed, the coarse precipitate is allowed to settle and is subjected to a liquid/solid separation.          Precipitate particles exceeding 35 mesh are commonly obtained.

Title: Apparatus for heat-strengthening glass sheets
Inventor: VEHMAS JUKKA H
IPC: C03B27/044
Filed: 1991-12-23
Abstract: (57) Abstract The invention relates to an apparatus for heat-strengthening glass sheets. In a heat-strengthening station (3) down-stream of a heating furnace the cooling rate of a glass sheet is retarded by means of plates (9, 11), which are set above and below a glass sheet and return some of the thermal radiation back to a glass sheet and slow down convection. Thus, a glass sheet can be heat-strengthened by chilling it at a certain controlled cooling rate.  In order to make also the lower plate effectively return some of the termal radiation applied thereto de-spite the rolls fitted in between, the top surface of lower plate (11) is made highly reflective to thermal radiation and further corrugated in a manner that the ribs of corrugations extend between the rolls close to a glass sheet.

IPC: A47K10/38
Filed: 1992-02-06
Abstract: Dispenser for Coiled Material Having Improved Operator Actuator and Drive Mechanism Abstract A  dispenser  for  coiled  material  has  an improved operator actuator and drive mechanism.   An actuator or button is conveniently located on the front of the dispenser, and the actuator or button, when pressed or pushed by the operator, activates a horizontally reciprocative gear rack to drive a drive roller   and   an   idler   roller   to   dispense   a predetermined  length  of  coiled  material  from  the dispenser.  The horizontally reciprocative gear rack has grooves which act on the drive gear to move the drive roller in a given direction when actuated by the operator.   A ratchet/slip clutch interconnects the drive gear and drive roller so as to provide for unidirectional movement of the drive roller, that is, movement of the drive roller in one direction when the user pushes the actuator, and no movement of the drive roller when the actuator is released by the operator and returns to its original position.   An idler gear on the idler roller and a drive gear on the drive roller coact to cause the idler roller and the drive roller to rotate in unison but in opposite directions.

Abstract: A radio pager receives a paging signal with a half-size microstrip antenna.  A pair of electrical conductive elements sandwich a printed circuit board on which elements constituting pager circuitry are mounted.  The conductive elements and conductive connecting pins fastening them constitute an electromagnetic shield case for the circuitry elements, reducing the radiation of unnecessary electromagnetic waves to the outside from the circuitry mounted on the printed circuit board, in particular from a local oscillation circuit.  Since the antenna has an earth plate thereof connected to one of the conductive plates with respect to high frequency, the conductive plate plays the role of an extension of the earth plate at the same time.  As a result, a microstrip base plate is miniaturized while the space available for parts is increased.  A ground conductive portion surrounds the antenna element and conceals screws and other conductive structural parts, whereby the antenna directivity pattern is not susceptible to changes in the dimension and position of the conductive structural parts.        The conductor of the antenna element may be formed with slits to further miniaturize the antenna element and, therefore, the entire pager.

Filed: 1992-06-09
Abstract: A mechanism for coupling vehicle components to a vehicle frame made of a plastic material.  A bolt is received by generally aligned openings defined by the frame and the component, and a first nut threaded onto the bolt securely presses the frame and component together.  A spacer or second nut carried by the bolt between the first nut and the component is positioned within the opening in the frame.  The spacer is slightly smaller in depth than the frame member, and allows the frame to become slightly compress.  The spacer limits the travel of the nut on the threads, thereby preventing the frame from being compressed beyond an elastic range of deflection.  A module plate having the vehicle engine thereattached is carried between the second nut and the vehicle component.  The second nut keeps the module plate and the component securely coupled together when the first nut is removed from the bolt, such that the module plate, the engine and the vehicle component can be removed from the frame as a single unit.
