Title: Spraying device having controlled additive fluid feed and a telescoping spray tube assembly
Inventor: PROCTOR RUDY R
IPC: B01F5/04
Filed: 1986-03-20
Granted: 1990-03-20
Abstract: ABSTRACT OF THE DISCLOSURE A spraying device includes a compound four-way rotatable control valve, an additive fluid control disc member and a spray selector disc member, whereby a primary fluid, such as water, and an additive fluid, such as detergent, can be sprayed or dispensed in various spray patterns separately, or as a mixture having selectively variable concentrations of the additive fluid in the primary fluid. The compound four-way rotatable valve is movable from an inoperative "OFF" position into first, second and third "WATER RINSE", "SOAP-AND-WATER" and "SUDS ONLY" operative positions. The control disc member includes a plurality of orifices of various diameters for controlling the amount of additive fluid dispensed into the primary fluid from a resilient bladder containing the additive fluid as the bladder is collapsed in response to external pressure thereon by the primary fluid. The spray selector disc member provides various spray patterns as the result of having orifices of various configurations formed therethrough and selectively positionable in alignment with a discharge orifice of the device. A telescoping spray tube assembly, which telescopes outwardly in response to fluid pressure, may be utilized in place of the spray selector disc member.

Title: Ball check valve
Inventor: HARBISON JOE A
IPC: F16K15/04
Filed: 1986-08-19
Granted: 1991-01-22
Abstract: BALL CHECK VALVE            Abstract of the Disclosure A check valve assembly includes a gener-ally bell shaped casing having a flared, open end section and a fluid inlet in opposed relation to the flared end section.  A body removably con-nected to the casing covers a portion of the flared end section and has a fluid outlet as well as two spaced, outwardly extending ball guiding members which are matingly received within opposed walls of the casing.  The ball guiding members are configured to shift the ball along a path of travel between a first, flow impeding position adjacent the fluid inlet and a second position spaced from the inlet and disposed laterally of a substantially straight fluid passageway extending between the inlet and the outlet.   In preferred forms of the invention, the path of travel of the ball has a variable slope which approaches zero as the ball reaches its uppermost, flow enabling position so that a minimum amount of fluid pres-sure on the ball can retain the latter in its uppermost position, ball flutter and fluid turbu-lence is substantially reduced.  In other forms of the invention, the body includes a stop which contacts the ball in a relatively small surface area of the latter when the ball is in its flow enabling position so that a portion of the fluid flowing through the valve assembly travels around the ball and cleanses the same, and so that stag-nant pockets of fluid are eliminated.

Title: Mixing cl gas into paper pulp slurries
Inventor: GAZDIK LAWRENCE E
IPC: D21C9/14
Filed: 1986-10-03
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE      Chlorine gas is directly introduced, without the necessity of adding water with the gas, into a paper pulp slurry (i.e. comminuted cellulosic fibrous material) having a consistency of between about 6-15 percent.          The gas is added to the inlet of a fluidizing mixer at the point where the slurry enters the fluidizing mixer, and is intimately mixed with the pulp by the mixer.  The flow of the chlorine gas is in a flow controlled pathway, which is split into at least two flows so as to increase the total gas volume added to the pulp stock and obtain enhanced mixing.  Each of the split flows is introduced to the inlet of a fluidizing mixer.  The split flow addition of chlorine gas into two or more mixer inlets also may be practiced for low consistency pulp (e.g. pulp having a consistency of between about 1-5 percent).

Granted: 1991-01-29
Abstract: Production apparatus comprising a step-wise driven conveyor device.     ABSTRACT         A production apparatus comprises a step-wise driven conveyor adapted to receive articles to be subjected to different operations.  Along the conveyor operative devices are arranged for carrying out the different operations to which the articles are to be subjected. The operative devices having comparatively short operation periods are stationarily arranged along the conveyor, whereas at least two operative devices having comparatively long operation periods, are movably arranged along the conveyor so as to follow the conveyor while the conveyor makes at least one step and then to be moved one such step opposite to the direction of movement of the conveyor. By such doubling of the operative device or devices having long operation periods, an increased capacity of the production apparatus is achieved.  The production apparatus can be used in producing ice cream cornets.

Filed: 1987-07-07
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE           A campstove burner includes a burner box which is located above the burner pan of the burner.  The burner rings are positioned between the burner pan ant the burner box, and a fuel and air mixture within the burner box flows through the burner rings where it is ignited.  Since the burner box is located above the burner pan, liquid fuel within the burner box will flow through the burner rings and will be ignited in the burner pan outside of the burner box.  The burner box in-cludes an L-shaped aspirator tube for mixing fuel and air.  An inlet end of the aspirator tube communicates with a source of primary combustion air, and a fuel tube extends into the outlet end of the aspirator tube for aspirating combustion air into the inlet end.  The burner box includes a generally cylindrical sidewall and the outlet end of the aspirator tube directs the fuel and air mixture generally tangentially to the inside of the cylindrical sidewall to promote swirling and mixing of the fuel ant air.

Title: Apparatus for actuating a breakaway conveyor section
Inventor: GROSJEAN ROBERT M
IPC: B65G43/00
Filed: 1988-03-04
Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for actuating a breakaway conveyor section includes an actuating means positioned below a lower edge of a fire door adapted to move vertically downward along an outside wall of a building to close an opening.  A breakaway conveyor section is pivotally connected to an end of a fixed conveyor section outside the building and extends adjacent to an end of a fixed conveyor section inside the building and extending into the opening in the wall.  The actuating means includes an actuating plate positioned below a lower edge of the fire door and pivotally connected to a pair of generally vertically extending slides by a pair of lever arms.  The slides are maintained in an upper posi-tion by a pair of link arms pivotally connected to form an over-center mechanism attached between the slides and the conveyor inside the building.  A lower end of the slides is slidingly attached to horizontal slides which extend through the opening in the wall to support a free end of the breakaway conveyor section.  When the fire door is released, it falls, striking the actuating plate which pivots about the vertical slides to release the over-center mechanism and allows the vertical slides to drop.  The falling vertical slides actuate the hori-zontal slides to retract them through the wall and allow the breakaway conveyor section free end to pivot down-wardly out of the way of the falling fire door.
