Abstract:
The ink jet print device has a multiplicity of plug-in type printheads (12) mounted on support plates (23). The support plates can be replaced and interchanged without difficulty by an operator. To this end, the print device is divided into a lower part and the actual printheads (12) such that, when the heads (12) are plugged in, the necessary mechanical, electrical, and hydraulic connections (27, 28, 29, 31, 26, 41, 33) between the heads (12) and the lower part of the print device are all established. Guide and locking means are used to ensure that the plugged-in heads are exactly positioned and held in place. The sockets for the individual heads (12) are each of identical design so that the simple replacement concept permits any printheads to be used for color printing and graphics and for printing with different droplet sizes.
Abstract:
The invention relates to apparatus for use in printing devices for the deposit of sheet-type recording media transported across a platen into a deposit tray area disposed above the platen. Deposit of the sheets is carried out by means of transport or delivery rollers which seize each sheet after it has passed through a printing area adjacent the platen and lift the sheet over a lower edge of the deposit tray for stacking. A pivotally mounted common carrier bracket is provided to carry a support wall which forms the lower edge surface of the deposit tray and the transport roller means. The support wall has a stripper surface formed along one end thereof containing bias means for resiliently pressing the recording medium into driving engagement against the transport rollers. The other end of the support wall is formed with intake guide surfaces for leading sheets into engagement with the intake side of the platen. The carrier bracket is pivotally rotatable so as to enable an operator easy access to the sheet feed path and the platen.
Abstract:
The present invention relates to a gas-monitoring assembly (100) and method for selectively determining the presence of a target gas in a gaseous environment that potentially comprises one or more interfering gases. Such gas-monitoring assembly and method specifically employ one or more gas sensors (S1) one or more getters (G1) arranged and constructed to reduce cross-interference caused by potential presence of the interfering gases in such gaseous environment to be monitored. The gas-monitoring assembly and method of the present invention are capable of monitoring a gaseous environment with respect to potential presence of multiple target gases that may interfere with one another.

Abstract:
At the underside of a substantially U-shaped support or carrier formed of steel there is affixed an intermediate element or part formed of an electrically conductive material, for instance copper or a copper alloy. This intermediate element carries at its bottom face or surface two contact supports or members formed of a suitable material, for instance AgCdO. At the ends or end faces of the U-shaped support there are attached arc conducting elements formed of a ferromagnetic material, for instance steel. The arc conducting elements protrude away from the base portion of the U-shaped support in the direction of the contact supports and extend laterally thereof up to the region of their contact surfaces. The arcs arising during contact opening directly transfer or shift from the contact surfaces to the arc conducting elements, without the arc base points migrating laterally from the contact supports to their connection locations. The contact supports or members as well as their connection locations are thus protected against destruction by the arcs.
Abstract:
A device includes a support (1) and at least two seals (2), which are arranged in a row and are hermetically fitted into cavities, and protrude from the support laterally with respect to inlet and outlet openings, one end of the support being provided with an inlet opening (3) and one end being provided with an outlet opening (4), and the seals being provided with a least one inlet opening and one outlet opening, and the support containing at least one first channel (5) which starts at the inlet opening (3) and is continuous, and is arranged in such a way that it opens into the inlet openings in the side walls of the seals arranged in a row, and one second channel (6) which starts at the outlet opening and is continuous, and is arranged in such a way that it opens into the outlet openings in the side walls of the seals arranged in a row. The system is suitable for simultaneous multiple studies, in particular with the use of microtitration plates, and physical measurements of the results directly in the containers, for example of a microtitration plate. The multiple studies may be used to perform screening processes to discover and develop polymorphic and pseudorpolymorphic forms, new formulations and suitable crystallisation conditions.

Abstract:
A detector plate includes a carrier plate, especially an injection-molded carrier plate, having a plurality of detector elements for detecting ionizing radiation. The detector elements function according to the principle of a Geiger-Müller counter. To simplify the production process and to save cost, the anode and/or the cathode should be in the form of a metallization on the carrier plate of the detector plate, the metallization(s) not being present in a single plane only. This configuration offers multiple options for designing the interior used as ionization chamber and for arranging the electrodes in this space. The options for contact with additional printed circuit boards also turn out to be highly advantageous. This further has an advantageous effect on the production process and on the qualities of the radiation measurement devices using detector plates of this kind.
