摘要:
The present invention consists of or includes an inlet device, of the valve type, used in a Central Vacuum System (CVS) and built into the skirting board, namely in the kitchen of a house. The function of the device is to collect dust and small debris with the aid of a broom into the entrance of this CVS, by means of a micro-switch activated CVS mechanism located in the skirting board, so as to avoid the use of a vacuum cleaner or vacuum tube also connected to the CVS. The device can comprise: a base body which can be assembled on the wall at the height of the skirting board; a cover which engages in the base body; an unlocking button which disengages the cover; a sealing strip which is glued to the base body; a micro-switch which engages in the base body; a helical torsion spring engaged in the cover, by means of a pin, which causes the cover to open in relation to the base body. By pressing the unlocking button the user causes the opening of the cover, which activates the micro-switch, which, in turn conveys an electric signal to the CVS so that it stars to vacuum.

The coupling of a sewer treatment station to a treatment plant for the flocculation and flotation of water streams and the insertion of said treatment plant for the flocculation and flotation of water streams into a water treatment station. The sewer treatment station is installed upstream from the flocculation and flotation treatment station, in such a way that the outlet of said station is directly connected to the inlet of the flocculation and flotation treatment plant disposed next to the stream bed or next to and interconnected thereto by means of a varying flow canal. The insertion has dynamic introduction of the process of treatment for the flocculation and flotation of fluid beds, all in a closed canal, wherein the flow of secondary streams (E) is dynamically and continuously submitted to flocculation and flotation techniques in an induced flow canal (FE) in the water treatment station.

Computer systems have resources that are often shared by plural processes (or threads). It is often desirable to limit access to these shared resources to one process at a time. Historically locks were used in conjunction with conditional tests to provide exclusive access to a region of code or data. Instead, a global variable contains a pointer to either a protected resource, or an exchange instruction. A process exchanges its' local variable with the global variable and jumps to the location in the exchanged local variable. If the global variable had the pointer to the shared resource before the exchange, then the jump enters the protected region. If not, the jump returns to exchange variables again. As soon as the pointer to the protected resource is returned to the global variable, a next exchange and jump will access the shared resource.

An accessory blade attachment adapted to removably attach to a ceiling fan blade of a ceiling fan is provided. The accessory blade attachment may include a blade portion and a pivotally connected fan clip, wherein the fan clip removably attaches to the trailing edge of the ceiling fan blade so that the blade portion may improve the volume and direction of airflow generated by the ceiling fan.

A method prepares a computer program for operation in a computer supply system that supplies portions, or program units, of program code or program data of the computer program as the program needs the portions. The method includes defining a program unit of the program and removing the program unit from the program, thereby producing a program skeleton that is missing the program unit. The method further includes inserting instructions in place of the program unit in the program skeleton. The instructions are operative to request the program unit when the program skeleton encounters the instructions. An information structure includes a program skeleton of a program. The program skeleton is missing a funclet of the program, but includes a placeholder in place of the funclet. The program skeleton additionally includes instructions in place of the funclet. The instructions are operative to request the funclet when the program skeleton encounters the instructions.
