Abstract: A sanitary fill head and sanitary fill head assembly for dispensing viscous flowable materials including a housing having an inlet passage for receiving the viscous flowable material and an outlet passage from which the viscous flowable material is dispensed, a product dispenser for dispensing the viscous flowable material from the outlet passage, and a product flow regulator for adjustably regulating the rate of flow of the viscous flowable material into the chamber to accommodate viscous flowable materials having different physical properties.

Abstract: An automated apparatus for the simultaneous filling of precise quantities of viscous liquid material to a plurality of containers in a sanitary environment, including a sanitary pump for delivering under pressure the viscous liquid material to a viscous liquid material manifold, a pump pulsation dampening assembly for dampening any pulsating output produced by the sanitary pump, and a plurality of fill valves for simultaneously dispensing a precise amount of viscous liquid material to the containers during a filling operation.

Abstract: A sanitary pump and sanitary valve is provided employing a dual action piston for providing a constant pressure metering and delivery of fluids utilizing a drive shaft positively driven and controlled by a drive motor for sanitary applications. The sanitary pump may be fabricated from materials which do not include surface imperfections that would allow the growth of bacteria or allow the contamination of products that may be precisely metered by the sanitary pump. The sanitary pump includes sanitary check valves for opening and closing a high speed dependably and reliably and cycles up to 200 cycles per minute and preferably in the range of 60 to 160 cycles per minute by providing guides for maintaining check valve stem stability. The sanitary pump further includes compression seals for sealing the drive piston to maintain high reliability and dependability in high speed constant pressure applications.

Abstract: A refrigerated showcase has a front opening through which a consumer can view and access foodstuffs on display. The foodstuffs are cooled by coolant air introduced through a slanted, perforated, interior panel located near a rear wall of the showcase. An air curtain directed downwardly at the front opening minimizes coolant air loss through the opening. Lips are applied and extended from edges of vertical sides of the access opening to reduce the loss of coolant air through the air curtain. Thus, relative flows of the coolant air and the air curtain are maintained inside the showcase.

Abstract: Continuous, random dyeing apparatus for carpet or the like comprising a plurality of elongate drums mounted for rotation on parallel, spaced axes, each drum having a plurality of cavities extending partially thereinto from the outer surface thereof, wiper means engaging the outer surface on one side of each drum, along a line parallel to the axis thereof, means for rotating the drums in a direction such that the one sides thereof move downwardy, and means for conducting a dyeing liquid to the intersections between each drum and its associated wiper means. The liquid fills the cavities in the drums, on the one sides thereof, as the drums rotate and the liquid in the cavities passes below the wiper means and is dispensed below the drum onto a carpet moving therebelow.
