Title: Nozzle head with a nozzle carrier that is rotatable about an axis and can be actuated
Inventor: HAMMELMANN PAUL
IPC: B05B3/00
Filed: 1990-01-24
Abstract: Nozzle head with a nozzle carrier that is rotatable about an axis and can be actuated Abstract:   1.   A nozzle head with a nozzle carrier that is rotat-able about an axis and can be actuated. 2.1  Tools with rotating spray nozzles on which high-pressure power water acts are used to clean surfaces as well as remove surface coatings.  Up to now the nozzles have sprayed dur-ing the entire 360° rotation.  Due to the feed of the tool, well-worn areas result in the feed direction to the left and right of the straight tangents.              The present invention is based on the object of using the energy expended in the well-worn areas in order to in-crease the feed. 2.2  The nozzle head comprises a stationary sleeve (10) through which the high-pressure water is fed and which extends up to the area of a nozzle carrier (12). Its free face end (15) is closed.  At least one transverse hole (16) is provided adjacent this face end (15), the channels (19, 20, 21, 22) arranged in the nozzle carrier and leading to the spray nozzles (18) being sup-plied from this transverse hole with pressure water.          2.3  The nozzle head is used to hydrodynamically clean horizontal or vertical surfaces.

Abstract: Contact Strip-to-Flex Bushing Connector Abstract The liquid crystal display of a portable computer is pivotally mounted with respect to a base fixed to the computer chassis.  The pivot mount is effected by means of a pivot shaft arrangement that operates, in addition, to secure the  opposite end portions  of  a  circuit strip extending between and electrically connecting the ter-minals on the display and the base, respectively.   The pivot shaft is axially split to secure an intermediate portion of the circuit strip whereby that portion of the circuit strip that extends from the base is windingly received on the exterior of the shaft to accommodate pivotal movement of the display. The other end of the strip is secured within the split segments of the shaft. and extends axially therefrom within the display housing.

Patent CA-2019007-A1 (CA)
Inventor: BARR FREDERICK J
IPC: G01V1/36
Filed: 1990-06-14
Abstract: A marine seismic reflection prospecting system reduces coherent noise by applying a scale factor to the output of a pressure transducer and a particle velocity transducer positioned substantially adjacent one another in the water.  The transducers can be positioned at a point in the water above the bottom and, thereby, eliminate downgoing components of reverberation, or they can be positioned on the water's bottom and, thereby, eliminate both upgoing and downgoing components of the reverberation.  The scale factor, which derives from the acoustical impedance of the water or water-bottom material, can be determined both deterministically and statistically.  The former involves measuring and comparing the responses of the pressure and velocity transducers to a pressure wave induced in the water. The latter involves comparing the magnitude of the pressure signal autocorrelation to the pressure and velocity signal crosscorrelation at selected lag values or, alternatively, comparing the magnitude of the pressure signal autocorrelation to the velocity signal autocorrelation at selected lag values.

Abstract: A tamper-evident closure for a wide mouth container. The closure member has a central panel and a downwardly opening rim cavity encircling the central panel and adapted to receive therein a top rim of the food container.  The rim cavity is defined by a pair of upstanding, radially spaced skirt segments connected at their respective upper edges by a top rim segment.  A radially outer one of the skirt segments has adjacent a lower edge thereof a radially inwardly projecting and circumferentially extending first flange adapted to snugly fit under and frictionally engage the lip on the food container.  In addition, the radially outer skirt also has a radially outwardly projecting second flange contiguous with and oriented below the first flange.  A plurality of generally inverted V-shaped radially outwardly projecting rim segments are integrally connected between each set of mutually adjacent circumferential ends of at least the second flange.  The inverted V-shaped rim segments each have a pair of wall segments each projecting radially outwardly from a respective one of the mutually adjacent circumferential ends of at least the second flange.  The pair of walls extend inclined upwardly from the second flange toward each other to and integral connection forming an apex. Each of the plural apexes defines stress concentration structure for the material of the closure member so that a lifting force applied to one of the second flanges will cause the material of the closure member to break only at the apexes.

IPC: B65H45/107
Filed: 1991-04-03
Abstract: Abstract Of The Disclosure A method and apparatus for fan folding a continuous web of paper having transverse fan fold lines in fan folds having a preselected fan fold length when the continuous paper is moved along a feed line from an upstream area to a folding area.  A controller energizes a drive motor to oscillate a discharge chute through a predetermined arc and at a predetermined rate to permit the continuous web of paper to be fan folded as the paper is moved through the discharge chute at the folding area.  The method includes the steps comprising advancing the continuous web of paper through the discharge chute, generating a first signal representing the speed at which the paper is advanced towards the discharge chute, generating a second signal representing a predetermined distance between the transverse fan fold lines; and oscillating the discharge chute in response to the first signal and the second signal to move the discharge chute through an arc and at a speed which enables the web of continuous paper to be folded in a zig-zag manner along the transverse fan fold lines.

Title: Gas sparged centrifugal device
Inventor: TORREGROSSA LOUIS O
IPC: B03D1/14
Filed: 1991-05-15
Abstract: ABSTRACT      A hydrocyclone establishes a first vortex of fluent material at one end (e.g. in a top portion), and a second vortex at the other end (e.g. in a bottom portion).  The first vortex is established within a porous surface of revolution to which gas or other fluid is supplied, passing through the porous surface into the first vortex.  The second vortex is established by a conical end section extending outwardly from (e.g. below) the porous surface, and with an axial (e.g. bottom) discharge for fluent material.  Some fluent material -- for example having heavy particles -- is removed tangentially from the conical end section at a portion near the porous surface of revolution.   A conical shroud having a circumferential periphery is mounted by a number of spaced legs connected between the shroud and the conical bottom section so that fluent material may pass between the circumferential periphery of the shroud and the porous surface of revolution.  An axial gas passage is provided in the shroud to allow gas to escape from the second vortex into the first vortex, and ultimately out the first end (e.g. top) of the hydrocyclone.  A plenum surrounding the porous surface of revolution may be divided into two or more axial portions, and liquid can be introduced into one of the plenum portions so that it experiences a pressure drop as it passes through the porous surface of revolution, thereby causing small bubbles to form..
