Abstract: A water bed mattress made from a watertight envelope is shown having a pliable sheet of polyethelene with gas cells uniformly spaced throughout the pliable sheet in a grid-like pattern for supporting baffles that are attached to the pliable sheet by sewing.

Abstract: A drinking receptacle cover comprises two layers of a rigid resilient material which are circular in shape. An annular downwardly opening channel is formed at the periphery of the two layers which are snugly assembled. This channel receives the top rim portion of a drinking receptacle, and to secure the assembled relation the outer wall of the channel is formed with an inwardly extending bead which engages said rim portion. Both layers have an opening adjacent to the channel. This opening is normally closed by a valve which is generally of the same shape as the opening and also comprises two layers. The lower layer comprises an inner vertical wall and two sidewalls which diverge towards the periphery and are joined at their outer ends by a curved endwall. These side and end walls are formed with a continuous outwardly extending flange. The top layer is also formed with an inner vertical wall, side walls diverging therefrom and a curved end wall.

Abstract: A cover for a drinking vessel of heat-insulating material comprising a cylindrical wall with elements at its lower end which cooperate with complemental elements at the upper end of a drinking vessel to provide a detachable bayonet joint. Integral with the upper end portion of the cylindrical wall is an inclined flat wall formed with a drinking opening and a relief vent in diametric alignment. Depending from the inclined wall substantially midway between said opening and vent are a pair of spaced lugs each having a journal recess opening onto its lower edge. A lever has a pair of studs extending from its opposite side faces and received in said recesses with snap fits. Upstanding from one end of the lever is an arm which projects through the drinking opening and carries a valve member on its upper end which is of greater extent than said drinking opening and normally engages the upper surface of the inclined wall about the drinking opening.

Abstract: The disclosure relates to an enclosed cup like drinking receptacle having a cover provided with a drinking opening therein which is disposed near the peripheral portion of the cover; the drinking opening being controlled by a liquid dispensing valve and a pneumatic pressure relief valve, both carried by a common manual actuator such that both valves are moved in unison and the dispensing valve being moveable relative to its seat a short distance without breaking its seal relative to said seat and to provide for sufficient movement of the pressure relief or vent valve to vent pneumatic pressure from the interior of said receptacle and cover so as to prevent unwarrented flow of hot beverages or the like through said dispensing valve and said drinking opening and thereby allowing a person to drink through said drinking opening with the normal flow of a hot beverage or other beverage therethrough.

Abstract: An apparatus for laminating articles with plastic of the type having supply rolls, pressure rollers and pull rollers through which a web of plastic is drawn. Heat shoes heat the plastic prior to the pressure rollers to cause an adhesive side to become fluent. The heat shoes have a large heating surface and are filled with sand. A plenum chamber directs cooling air onto the bonded web between the pressure rollers and pull rollers. The upper rollers are carried by a spring biased slide while the lower rollers are journaled to the frame. An eccentric mechanism mounted in the slide lifts the slide and upper rollers for threading and cleaning. A threaded linking member is attached between the slide and the top of the frame for incrementally lifting the upper pressure roller to allow single side lamination.

Abstract: A water bed for supporting a body thereon and which comprises upper and lower flat plastic sheets. A first rectangularly shaped continuous peripheral wall extends between and is sealed to the upper and lower sheets to form a water chamber therebetween. The first continuous wall is formed by adjoining four endwise connected segments along four rectangularly spaced corner margin. Each corner margin is formed by heat sealing two adjacent wall segments in the form of an arcuate shape with a reinforcing strip disposed over the corner margin and lap sealed to the two adjacent wall segments. The upper and lower walls extend beyond the first continuous peripheral wall and have flaps which extend in a vertically disposed direction to form a second continuous peripheral wall. These flaps are also lap sealed to each other in order to form the second continuous peripheral wall which thereby forms an air chamber surrounding the water chamber.

Abstract: A drinking receptacle provided with a generally cup-like body and an enclosing cover removably coupled to the top portion and upper open end of the cup-like body; the cover having a drinking or outlet opening near the peripheral rim thereof; and a finger operated valve adapted to open and close said drinking or outlet opening whereby the receptacle may contain hot or cold beverages therein and the valve prevents spillage of said beverages at times when beverages are not being poured or drunk from said drinking or outlet opening. The finger operated valve having an actuator portion reciprocally mounted in the side of the cover or in the side of the drinking receptacle and being coupled directly to and integral with the valve whereby pressure on the actuator by a persons finger may directly open the valve in such a manner as to allow liquid to pass through said drinking or outlet opening.

Abstract: The disclosure relates to a drinking receptacle and valve means wherein: hot or cold liquids may be safely contained and carried during intermittent drinking such that the liquids cannot be spilled and in the case of hot liquids the valve means is manually operable to open the drinking valve to allow drinking of liquid from the receptacle or container. The valve means comprising a lost motion mechanism coupled with a manually operable plunger such that the manually operable plunger first opens a relief valve to relieve steam and pressure from the interior of the container whereupon the plunger continues its motion to open the drinking valve so as to allow drinking of contents from the receptacle after steam and pressure has been relieved therefrom and to thereby avoid the danger of causing hot coffee or other beverages to gush from the drinking valve when opened.
