Abstract: A B S T R A C T           A method of manufacturing a sandwich panel in which two rigid or semi-rigid skins are mounted in spaced, substantially parallel vertical relation with the panel edge members extending across the gap between the low edges of the skins.  At least one nozzle is introduced between the upper edges of skins and a liquid foam forming material is projected laterally against the inner services of the skins, adjacent the upper edges thereof, and the liquid is allowed to flow downwardly to wet substantially the entire inner surface of each of the skins.  The introduction of the liquid is continued until sufficient foam forming material has been introduced into the space between the skins to obtain the desired foam interior under the prevailing conditions.  The gap between the upper edges of the skins is closed and the foam is allowed to expand and fill the space between the skins and thereafter to cure.

Title: Method and apparatus for foaming high viscosity polymer materials
Inventor: COBBS WALTER H JR
IPC: B05C5/00
Filed: 1988-03-16
Granted: 1991-12-24
Abstract: Method And Apparatus For Foaming High Viscosity Polymer Materials Abstract of the Disclosure Polymer materials having viscosities ranging from about 50,000 up to above 1,000,000 centipoises are mixed with a gaseous foaming agent to provide a polymer/gas solution under pressure such that when the polymer/gas solution is subsequently dispensed at atmospheric pressure the gas is released from the solution and becomes entrapped in the polymeric material to form a homogeneous polymer foam.  Mixing is accomplished by force feeding the gas and polymeric material into and through a low energy input disk mixer with a low pressure drop across the mixer such that premature foaming or reaction of the polymeric material is avoided.  The disk mixer includes a tubular housing, one or more driven shafts extending along the length of the housing, and a series of disks spaced along the shafts.  The foaming gas enters into solution in the polymer in the compartments between the rotating disks.  The process is characterized in that relatively high viscosity polymeric materials are mixed with gas and foamed with relatively low horsepower requirements, high throughput and low temperature rise of the polymer from conversion of the work of mixing to heat.

Abstract: ABSTRACT OF THE DISCLOSURE    A fiberglass reinforced molded resin grating is formed of first and second sets of mutually parallel,  interlocking fiber-glass  reinforced  molded  resin  bars  with  the  sets  extending transversely to one another.  One set consists of bearing bars of rectangular  cross  section including  at  longitudinally  spaced positions within an upper edge, inverted U-shaped notches includ-ing oppositely directed, downwardly and outwardly oblique slots terminating at their upper ends adjacent the upper edge of the bearing bars  in upwardly  and outwardly diverging oblique  cam surfaces.   The  second  set  of  bars  consist  of cross bars  of inverted  U-shaped  cross  section  including  a  horizontal  base portion and a pair of downwardly and outwardly diverging legs of a thickness equal to the width of the diverging slots and being respectively received in said slots. The legs of the cross bars at longitudinally spaced position are provided with rectangular locking notches from the free ends upwardly of a width generally equal to the thickness of the bearing bars and of a height which is less than the vertical height of the cross bars.  The cross bars are forced downwardly at the locking notches into the inverted U-shaped notches formed within the upper edge of the bearing bars with the cam surfaces deflecting the oblique legs of the cross bar to momentarily deform the legs to cause the portions of the legs at the locking notches to snap into the oblique slots of  the  inverted U-shaped notches within  the bearing bars  to mechanically interlock the  first and second  sets of the bars together.

Title: Electrically controlled fluid mixing fixture, especially for mixing hot and cold water
Inventor: BLAETTLER ERNST
IPC: G05D23/13

Granted: 1992-06-30
Abstract: INVENTOR:  ERNST BL?TTLER            INVENTION: ELECTRICALLY CONTROLLED FLUID MIXING FIXTURE, ESPECIALLY FOR MIXING HOT AND COLD WATER     ABSTRACT OF THE DISCLOSURE     In the fluid mixing fixture, a displacement body and  a  tubular  shell,  which  coaxially  encloses  the displacement body, are arranged at an inflow element.  A temperature measuring element, such as a nickel wire which is covered by a plastic jacket, is wound around the tubular shell at the region of an annular gap formed between the displacement body and the tubular shell.  Hot water and cold water flow through inflow openings of the inflow element and into a recess or chamber thereof, at that location the hot water and cold water are admixed and then the admixed water flows through the annular gap to an outflow opening.  Since the flow cross-sectional area of the annular gap is smaller than the inflow cross-sectional area of the inflow openings the velocity of the admixed water is increased.  This promotes further, admixing of the hot and cold water and enhances heat transfer to the tubular shell.  A radial temperature gradient cannot develop in the annular gap, so that the temperature of the water can be measured extremely accurately.   Measurement  of  the  water  temperature  is accomplished very close to the location of intermixing of the hot and cold water, allowing exceedingly rapid detection of changes in the temperature of the admixed water.  To attain the desired mixed water temperature valves are regulated by means of a control.     WWK:sm:sncd7

Title: Apparatus for the formation of an insulating material  ply
Inventor: SOIKKELI OSMO
IPC: B28B1/52
Filed: 1989-01-27
Granted: 1994-01-11
Abstract: Abstract The invention relates to an apparatus for the forma-tion of an insulating material ply, e.g. in the manu-facture of insulating chutes. The object is to provide a continuous insulating material ply (17) of a prede-termined  thickness.  A primary ply  (14)  of  surplus thickness is first sawn out of an insulating material roll (1) by rotating the insulating wool roll against the edge of a band saw, and this primary ply (14) is fed to another ply-cutting saw (16) which saws the primary ply into the final ply (17) with the predeter-mined thickness. The surplus from the primary ply (14) is collected on a drum (19) provided in connection with the ply-cutting saw (16) to form an intermediate storage. When the insulating material roll  (1) runs out, the sawing of the final ply (17) is continued from  the  intermediate  storage without  interruption until the leading edge of a new opened insulating ma-terial roll (1) reaches the ply-cutting saw (16).
