A flow-through fluid heater comprises: a high thermal conductivity conduit-defining body shaped to provide a conduit that extends between an inlet port and an outlet port; one or more heating elements connected to the body for providing heat to the body, thereby permitting the body to provide heat to fluid flowing through the conduit; a temperature sensor connected to sense a measured temperature indicative of a temperature of the fluid in a vicinity of the temperature sensor; one or more flow rate sensors for sensing a measured flow rate of the fluid through the conduit; and a controller connected to receive signals from the temperature sensor and the flow rate sensors, the controller configured to control an amount of heat energy imparted to the fluid during a period that the fluid is resident in the conduit between the inlet port and the outlet port based at least in part on the measured temperature and the measured flow rate.

Disclosed herein is a plate-type heat exchanger or chiller, with multiple stacking plates stacked one on top of the other such that a first fluid duct for a first fluid and a second fluid duct for a second fluid are formed between the stacking plates. A first inlet and outlet opening for conducting in and discharging the first fluid, and a second inlet and outlet opening for conducting in and discharging the second fluid is provided. The first inlet or outlet opening is formed by an immersion pipe and the first fluid can be conducted into the first fluid duct through the immersion pipe, such that the first inlet and outlet openings are formed on the same side of the heat exchanger.

An apparatus for selectively extending and retracting spikes includes spike actuating assemblies mounted to, and cooperating between, a first plate and a first slider frame, and a second plate and a second slider frame, pivotally mounted to the first plate and first slider frame respectively. Each spike actuating assembly contains a spike. The first slider frame is translatable to actuate the spike actuating assemblies to thereby extend and retract the spikes from the spike actuating assemblies. A cyclically alternating positioner is mounted on the first plate for moving the first and second slider frames relative to the first and second plates. The positioner has only a single actuating button adjacent the heel. Depressing the actuating button a first time causes the positioner to move the slider frames to extend the spikes. Depressing the actuating button a second time causes the positioner to move the slider frames to retract the spikes.

A cleaning card for use in cleaning internal surfaces of machine components includes a substrate having a central plane between opposed surfaces thereof, a machine direction dimension defined between opposed end edges and a transverse direction dimension defined between opposed side edges. The substrate includes an embossment forming angled, substantially non-collapsible, elongate raised ridges on opposite sides of the cleaning card substrate, with the raised ridges being oriented at an angle to the machine direction for incrementally wiping transversely across the internal surfaces to be cleaned, which can include peripheral surfaces of idler rolls. Preferably the opposed surfaces of the substrate each have a plurality of discrete, raised and collapsible working areas for engaging and cleaning internal surfaces of machine components.

A tonneau cover is arranged to mount on the truck box of a conventional pick up truck for enclosing the box. The cover comprises a pair of panels which are pivotally mounted on respective sides of the box. The panels extend laterally inward such that free ends of the panels engage each other in a closed position. The panels may be pivoted upward and secured in an upward orientation by a pair of rails connected between the free ends of the respective panels in an extended position of the panels. The panels form a pair of side walls in the extended position for supporting large cargo in the box. The rails form a rack in the extended position for supporting additional cargo thereon. A locking device secures the panels in the closed position while a plurality of struts provides additional support to the panels when pivoting the panels between the closed and extended positions.

Electrical power strips and electrical power strip assemblies are disclosed. An electrical power strip assembly includes electrical outlets for receiving power cord plugs. Strap mounts are provided, wherein each strap mount includes a connection point associated with one of the electrical outlets. A housing supports the electrical outlets in a connection plane and supports the plurality of strap mounts. Each strap mount connection point is proximal to the connection plane and to the electrical outlet associated with that strap mount connection point. Straps are coupled to the strap mounts. Each strap is configured to releasably secure a power cord plug received by one of the electrical outlets to the associated strap mount at the connection point.

A cleaning card for use in cleaning internal surfaces of machine components, including internal, rotatable idler rolls, includes a substrate having a central plane between opposed surfaces thereof, a machine direction dimension defined between opposed end edges and a transverse direction dimension defined between opposed side edges. The substrate includes an angled embossment forming angled, substantially non-collapsible, elongate raised ridges on opposite sides of the cleaning card substrate, with the raised ridges being oriented at an angle to the machine direction for incrementally engaging an idler roll surface along its axial extent as the raised ridges pass through a nip including the idler roll to aid in both rotating and cleaning one or more idler rolls. In preferred embodiments the opposed surfaces of the substrate each have a plurality of discrete, raised and collapsible working areas for engaging and cleaning internal surfaces of machine components in addition to idler rolls. In the most preferred embodiments, discrete, raised and collapsible working areas cooperate with the raised ridges for aiding in cleaning idler roll(s).
摘要:
The invention refers to a method which generates an IC tester control consisting of numerous test instructions for a plurality of specific test environments, which can generate and measure analog and digital signals for an IC, in particular a mixed-signal IC. The method obtains data and control instructions from multidimensional test matrices independent of the test environment, such as matrix-like databases or libraries. The data and control instructions independent of the test environment are converted by means of a code generator into a syntax which is dependent on the test environment and which can be integrated into a general syntax dependent on the test environment, so that the syntax dependent on the test environment and the general syntax dependent on the test environment together form a complete control, comprising analog and digital signals, for one of the specific test environments.
