Abstract: Abstract of Disclosure A spray gun especially adapted for dispensing foam type plastics or other coating materials which is characterized by two feed lines for the coating materials which are encased in return lines with valves which are selectively positioned to control the flow of the material so as to provide, selective-ly, for spray operation or for continuous return flow to the supply source without passage through the discharge control valves of the gun. The discharge control valve assemblies are readily removable as complete units for cleaning and repair. A solvent flush valve is arranged relative to the discharge control valves to enable the valves, the mixing chamber and passageways in the head to be flushed out with solvent while the valves are in place and while the coating material is recirculated through the supply lines.

Abstract: Abstract of the Disclosure A building panel has first and second opposed marginal ridges.  The first of the marginal ridges is provided with an attachment zone whereby the panel is attachable to a building structure by at least one fastener.  The second marginal ridge is of different cross-section but partly complementary to the first marginal ridge and can be laid in overlapping relationship over a first marginal ridge of an identical panel already attached to a building structure.  The central portion of the second mar-ginal ridge of the other panel and the central portion of the first marginal ridge of the other panel are rigidly connected together by a fastener passing through the central portions of these ridges and spaced from the structure to prevent longitu-dinal relative movement of the ridges and thus to form a compo-site ridge.  The overlapping marginal ridges define a cavity adjacent the attachment zone and intermediate the second mar-ginal ridge of the one panel and the first marginal ridge of the other panel.  The cavity receives a head of the fastener attach-ing the attachment zone to the building structure.

Abstract: ABSTRACT OF THE DISCLOSURE     A food cooker is illustrated in the form of a deep-fat fryer, in which the fat is isothermally heated to an operating temperature below a temperature range in which an unacceptably high rate of undesirable decom-position products formation occurs in the cooling liquid.  The heat transfer process used is vaporization and condensation of a confined liquid essentially isothermally and substantially at the working temperature.  Condensation of the heat transfer vapor takes place at an outer surface of the container for the fat.  Heat is applied to the heat transfer liquid remote from the con-tainer, which having no heating element or elements intruding into its in-terior is easy to clean.  Heat is transferred to the cooking fat by conden-sation of the heat transfer vapor essentially only as it is used by the load being cooked.  Hot spots are minimized, so that the formation of undesirable decomposition products of the cooking fat is retarded.  The volume of cooking fat required to cook a given load can be reduced, and its useful life extended.

Abstract: ABSTRACT OF THE DISCLOSURE           A two piece portable toilet is described.  The toilet includes a bowl unit which defines a toilet bowl having a discharge opening, and a reservoir for a flushing liquid, said reservoir having a normally closed filler opening.  A holding tank is normally disposed below and supports the bowl unit.  The holding tank has a top wall and defines a waste holding chamber having an inlet opening in said top wall for communication with the discharge opening of the toilet bowl.  The chamber also has a nor-mally closed outlet opening.  The top wall of the tank is contoured to define a depression around the holding chamber inlet opening and, on opposite sides of the de-pression, surfaces for supporting said bowl unit, whereby the top wall has a generally downwardly domed configuration.          Coupling means normally maintain the bowl unit and holding tank in co-operating relationship when the toilet is in use.  The coupling means allow the unit and tank to be separated at appropriate times.  The toilet also includes pump means communicating with the reservoir in the bowl unit and with the toilet bowl and operable in use to deliver flushing liquid from the reservoir into the bowl.          Valve means are also provided for controlling discharge of material from the toilet bowl into the holding chamber.          The valve means are disposed in the depression in the top wall of the holding tank and includes a flap-form closure member which is pivotable about an axis generally normal to the axis of the discharge opening of the toilet bowl.          The closure member is movable between a position in which the member prevents communication between the discharge opening of the bowl and the waste holding chamber, and a position in which the closure member has pivoted down-wardly clear of the opening to allow discharge of material from the toilet bowl into said chamber.  A valve operating means is normally disposed below and supports the closure member in its closed position and is retractable to allow the closure member to pivot downwardly about its said axis and allow communication between the discharge opening of the bowl and the inlet of the waste holding chamber.
