Abstract:
A microfluidic probe head includes a first layer, a second layer, and a first tubing port extending from an upper face of the first layer. The first layer has a first via, enabling fluid communication between the first port and a lower face of the first layer. The second layer includes a first aperture on a face, and a first microchannel enabling fluid communication between an upper face of the second layer, facing the lower face of the first layer, and the first aperture. The head enables fluid communication between the first via and the first microchannel. At least a portion of the first microchannel is a groove open on the upper face of the second layer, closed by a portion of a lower face of a layer of the head. The probe head further comprises a second tubing port, a second via, a second aperture and a second microchannel.
Abstract:
A system for supplying a process gas to a processing location 7 of a particle beam system 1 comprises a gas reservoir 63; a gas conduit 65; a pipe 69 located close to the processing location; a valve 67 provided between the gas conduit and the pipe; and a controller 71 configured to open and to close the valve to switch the system from a first mode of operation in which process gas is not supplied to the processing location to a second mode of operation in which process gas is supplied to the processing location. The controller can alternately open and close the valve in cycles, wherein each cycle includes a first duration in which the valve is open and a second duration in which the valve is closed, wherein a ratio between the first duration and the second duration can be changed.
Abstract:
A method for recovering blood from a blood-laden surgical sponge for autologous reinfusion, the method comprising the steps of: conveying negative pressure to a housing with the blood-laden surgical sponge; applying a predetermined force to draw the blood from the surgical sponge; and collecting the recovered blood.
Abstract:
A plumbing component includes a valve provided within a portion of the plumbing component and configured to control the flow of water through the plumbing component. The valve includes a body and at least one waterway within the body. An electric heater extends through at least a portion of the body of the valve and is configured to heat at least a portion of the body to an elevated temperature sufficient to kill organisms within the waterway.
Abstract:
The present application relates to improved valves, especially valves for plumbing fixtures, fittings and water supply systems and installations for washing, showering, bathing and the like employing such plumbing fixtures and fittings, are disclosed herein. The concepts have particular, but not exclusive, application to a mixer valve, especially to a thermostatic mixer valve and, more particularly, to an electronically controlled thermostatic mixer valve. In other embodiments, the concepts may be applied to flow control valves and to applications of such flow control valves in plumbing fixtures and fittings and parts thereof including, for example, a mixer valve.

Abstract:
A method is provided for controlling a hydraulic cylinder in a work machine, which hydraulic cylinder is arranged to move an implement that is subjected to a load, with the hydraulic cylinder being controlled by a hydraulic machine. The method includes detecting that a lifting movement of the implement is to be initiated, and attaining a basic speed of the hydraulic machine before lifting takes place.
