Abstract: A one-way valve (25) is mounted in a housing body (11) and couples an inlet chamber (12) with a discharge chamber (13) so as to prevent the passage of fluid between two chambers except through the valve. The valve has its inlet end in communication with the inlet chamber. The valve has its outlet end in communication with a discharge chamber. The vale is adapted to permit the irreversible passage of drainage material passing through from its inlet end to its outlet end.

Abstract: 1. Method for separating of unglued cardboard-backed paper pads from a pile with a plurality of flush-edged cut paper layers (12) and cardboard inserts (14), characterised in that the pile abuts against an abutment means at its end which is covered by the end-sheet (12') in such a way that part of the pile freely protrudes over one edge of the abutment means ; that a force diagonal relative to the end of the pile is exerted against a point of application at the cutting surface of the protruding part of the pile which force bends the pile portion between the point of application and end-sheet whilst forming a wedgeshaped gap ; that the point of application of the force is displaced in the direction of the pile end so that a part of the bent paper layers (12) and cardboard inserts (14) spring back toward the pile under the influence of their resilience whereby the point of application is displaced until the last cardboard insert has sprung back and the last paper layer (12') including end-sheet (16) is bent away ; then the last paper layer (12') including end-sheet is separated from the remaining pile by entering into the wedgeshaped gap (15), thus forming a paper pad including cardboard back, and the last backward bent cardboard insert becomes the end-sheet during repetition of the separating process.

Date Jan. 14, 1988.A method is provided for restoring a refractory lining for repeated use. The lining is present on a underlying wall surface and is still hot from a previous use when one induces thermal shock in the lining (e.g. by spraying water on it) so as to loosen it. The loosened pieces are then pried away from the wall surface, and they are removed from the area. The residual lining is milled to expose a sound, underlying wall surface, and fine particles, dust, and milled-off pieces are removed. The underlying wall surfaces are thus made speedily available for relining and reuse.

Abstract: A method of manufacturing one or more nozzles (13) for an ink jet printhead initially comprises bonding a nozzle plate (14) to the ink ejection end of the printhead (16). A mask (12) is then secured in contact with the nozzle plate (14), the mask having a plurality of apertures (15) each defining a respective nozzle exit. Laser radiation applied to the mask exposes the areas defined by the apertures to ablate the plate material between the nozzle exits on the external surface of the plate and corresponding nozzle inlets on the opposite surface of the plate. The assembly comprising the printhead (16), plate (14) and mask (12) is rocked during the exposure step to increase the area of the nozzle inlet relative to its outlet. Also, prior to the nozzle formation step, one or more ink troughs (22) may be provided for supplying an external source of ink for each nozzle. The ink troughs (22), which may be formed using laser ablation techniques similar to those used in the formation of the nozzles, facilitate a continuous, positive flow of ink through the nozzles.

The controller includes a shifting unit influenced by a sensor detecting the shift from the first lane to the second.  The shifting unit is operable during the introduction of the shifting lever from the first lane into the second to maintain the actually engaged transmission speed for a length of  time such that a rotational speed of a driving internal combustion engine has not yet exceeded an upper limit or dropped below a lower limit, or the lever has not yet been displaced in the second lane.

Abstract: Composite solder articles contain a first portion of a first solder having a first melting point, T1, and a second portion of a second solder having a second melting point, T2, which is at least (T1+10) DEG  C. Such articles are useful as the sole solder-producing inserts in heat-recoverable solder connection devices. When the device is heated, the second solder will not melt until the first solder has melted and flowed. Thus the second solder portion can indicate when the first solder has flowed, and/or can control flow of the first solder.
