Abstract: NEUTRAL HYDROCARBOXYCARBONYL THIONOCARBAMATE              SULFIDE COLLECTORS                 ABSTRACT OF THE DISCLOSURE New and improved collector compositions for use in froth flotation processes for the beneficiation of mineral values  from base metal sulfide ores are disclosed.   The collector compositions comprise at least one hydrocarboxy-carbonyl thionocarbamate compound selected from compounds of the formula:                        wherein R1 and R2 are each,  independently,  selected from saturated and unsaturated hydrocarbyl radicals, alkyl poly-ether radicals and aromatic radicals, or such radicals op-tionally substituted by polar groups selected from halogen, nitrile and nitro groups. The use of the hydrocarboxycarbonyl thionocarbamate   collectors   provides   excellent   metal-lurgical   recoveries  of  sulfide mineral values in froth flotation processes conducted over a broad range of pH con-ditions including acid, neutral and mildly alkaline pH.

Abstract: ABSTRACT    A beverage dispensing system and distributing process with such a system has a flexible bag 1 containing the beverage which may have carbon dioxide dissolved therein.   The beverage is drawn, off through a pipe 3 (assisted by a pump 8) for dispensing through nozzle 5 having a tap 6.   Carbon dioxide, nitrogen (or other inert gas) and/or air gases are introduced into the beverage through a passage 11 by way of a fixed orifice restrictor 12 and a non-return valve 13.          The pressure of the gas which is introduced is adjustable at 14 and baffles 15 can provide turbulence in the beverage during dispensing to promote the dissolution of the introduced gas therein.    The facility to introduce the gas or gases permits-the-beverage in the bag 1 to have a low content of carbon dioxide so that the bag collapses under atmospheric pressure while the beverage as dispensed is additionally  gasified for the formation of a froth or head.

Title: Surface erosion using lasers
Inventor: MARSHALL JOHN
IPC: A61B17/30
Filed: 1986-09-09
Granted: 1991-01-15
Abstract: ABSTRACT OF THE DISCLOSURE         Laser apparatus for eroding a surface comprises means to select and control the shape and size of the area irradiated by each pulse of laser energy without varying the energy density of the beam.  By varying the size of the irradiated area between pulses, some regions of the surface may be eroded more than others and so the surface may be reprofiled.  The method and apparatus are suitable, inter alia, for removing corneal ulcers and reprofiling the cornea to remove refractive errors and also for reprofiling optical elements.  In one embodiment the beam from the laser enters an optical system housed in an articulated arm and terminating in an eyepiece having a suction cup for attachment to an eye.  The optical system comprises a beam forming arrangement to correct an asmymetric beam cross-section, a first relay telescope, a beam dimension control means and a second relay telescope.  The beam dimension control means comprises a stop having a shaped window or a shaped stop portion and movable axially along a converging or diverging beam portion.  An alternative beam dimension control means comprises a stop having a shaped window and positioned between coupled zoom systems.  Mirrors adjustable slits and refractive systems may also be used.  The laser is preferably an ArF excimer laser.  The apparatus may comprise a measurement device to measure the surface profile, and a feedback control means to control the laser operation in accordance with the measured and desired profile.

Abstract: TRANSLATIONAL ACCELEROMETER AND ACCELEROMETER ASSEMBLY METHOD             Abstract An accelerometer comprising a body (10, 16, 12), a proof mass (18, 30, 32), mounting means comprising flexures (20, 22) for mounting the proof massto the body, and force sensing means (34, 38). The flexures permit translationalmotion of the proof mass with respect to the body along a sensitive axis SA and rotation of the proof mass with respect to the body about a hinge axis HA that is perpendicular to the sensitive axis. Acceleration of the accelerometer along thesensitive axis results in translational motion of the proof mass along the sensitive axis. The force sensing means reacts to such translational motion by producing asignal indicative of acceleration along the sensitive axis. In a preferred embodiment, the mounting means comprises a pair of fused quartz flexures that are oppositely directed with respect to one another, and the sensing means comprises a pair of vibrating beam force transducers that are connected to the proof mass on opposite sides of the binge axis from one another. The described assembly method for accelerometers comprises forming bridges between the proof mass and body, the bridges being removed after attachment of the force transducers.

Granted: 1991-07-30
Abstract: ABSTRACT           A mask arrangement particularly adapted for use in cold weather conditions includes a mask member and a spaced eye shield.  Air flow directing means directs air flow between the eye shield and the mask member, providing comfortable air flow and inhibition to fogging of the eye shield.  The mask member is divided into a vision region and a breathing region.  The vision region includes a port therein covered by the eye shield.  The breathing region is generally isolated from the vision region and includes a breathing aperture with baffle means associated therewith.  In a preferred embo-diment, the breathing aperture comprises a large aper-ture in the central portion of the breathing region, with the baffle means comprising a baffle plate mounted over the breathing aperture.  The baffle plate generally deflects air preventing jetting directly into the mouth of the wearer.  Relative constant spacing between the eye shield and the mask member facilitates air flow without substantial turbulence.

Abstract: ABSTRACT OF THE DISCLOSURE     A tendon for use in pestressed concrete is made up of a plurality of individual elements such as strands of steel wire arranged in a uniform array around and spaced radially out-wardly from a center point.  A spacer for the tendon includes a star-shaped base formed by arms extending radially outwardly from a central part.

An intermediate part is positionable within the triangularly shaped openings for separating the elements located within the opening.  The intermediate parts have a radially extending web and a flange extending trans-versely of the web for dividing the opening into separate spaces for each tension element.  During assembly, the base is inserted into the tension member for separating the tension element and then the intermediate parts are inserted for spacing the elements from one another.  The spacers are in-tended for use at a change in direction point of the tension member and initially are assembled at a positon spaced from the change in direction point and then are moved to the point.
