摘要:
A soft landing control system for a screeding device is operable to automatically lower a vibrating member relative to a grade setting device after the grade setting device is lowered to the desired grade. The control may be operable to delay lowering the vibrating member relative to the grade setting device at least until the control receives an input indicative of at least a portion of the screed head assembly being moved to a position generally over a newly placed concrete area. Optionally, the control may delay lowering of the vibrating member relative to the grade setting device until a period of time has elapsed after an activating event. Optionally, the control may automatically stop vibration of the vibrating member when the screed head assembly is not moving in the screeding direction and may automatically vibrate the vibrating member when the screed head assembly moves in the screeding direction.

A sanitizing method and a sanitizer system to be attached to a conventional circular beverage can filling machine, the system including a plurality of collector manifolds, each manifold being adapted to collect sanitizing liquid from a plurality of adjacent can filler valve centering bells, there being sufficient number of manifolds with plural bell sealing rings to accommodate every filler valve of a particular machine; the manifolds are connectable by flexible hoses to a rotating collector which is preferably permanently installed at the top of the can filler machine; the entry ports of the collector rotate with the rotating conveyor table of the machine and the exit port of the collector is from a stationary portion thereof. There is a provision for passage of carbon dioxide gas through the center of the collector to maintain carbonation in the beverage in the filler bowl. Clamps are provided for the manifolds to hold their sealing rings firmly up against the taper of the filler valve centering bells. Hoses are connectable to the manifolds by quick connect fittings; the manifolds are completely removable and there is no modification required to the filler valves or other parts of the machine which might interfere with the normal filling operation.

An improved multi-fluid jetting device. The jetting device includes a nozzle plate having a substantially planar surface for ejecting a fluid therefrom. The nozzle plate has at least 10 or more nozzles wherein groups of three adjacent nozzles are arranged in a triad orientation and wherein at least two adjacent nozzles in said triad orientation are coupled to two different fluid sources for fluid ejection from said adjacent nozzles substantially perpendicular to said nozzle plate surface.

A hermetic glass-to-metal seal between a conductive pin and an outer body, wherein a corrosion-resistant noble metal (e.g., gold) coating is applied to the conductive pin before the hermetic seal is formed. The noble metal-coated conductive pin is located in glass having a softening point less than about 650° C. and disposed in a cavity of the outer body. This is accomplished by inserting the coated conductive pin into a bore in a glass preform, heating the assembly to a temperature in excess of the softening point of the glass but less than about 700° C., and cooling the assembly. The coefficients of thermal expansion of the components of the assembly are preferably selected such that the resulting assembly is a hermetic compression seal.
