Patent DE-2936641-A1 (DE)
Title: CRT funnel provided with external resistor - reducing fluorescence time after switch off
Inventor: FISHER MAHLON B
IPC: H01J29/96
Filed: 1979-09-11
Abstract: Cathode ray tube comprises viewing screen, funnel and neck portions joined together and having the funnel portion provided with a clad anode button and internal and external conductive coatings covered it at least partly is described. The improvement is that a resistance is fixed on the external surface of the funnel section, and it connects electrically the anode button and the external conductive coating such that the indicia of a dispersed emission appearing on the screeen at the moment of interruption of a high tension potential applied to the anode button, are dissipated in a regulatable manner. The resistance prevents the persistence of fluorescence at switch off and allows the television manufacturer to dispense with the use of a high tension supply resistor or a leak resistor, without morbedly increasing the cost to the manufacturer.

Title: Mounting box for electrical installation apparatuses
Inventor: SPELSBERG ECKHARD DIPL ING
IPC: H02G3/12
Filed: 1981-03-28
Abstract: In the case of a mounting box for electrical installation apparatuses for fixing on a mounting wall which has hook projections and is preferably a component of a cable duct, the mounting box is mounted in the interior of said cable duct by means of holders which can be attached to the hook projections and overhang the base of the box underneath. These holders are intended to be capable of being detached and fixed for locking from the front side, without there being any necessity to detach any installation and wiring of an installation apparatus in the mounting box again. For this purpose, the holders consist of sliding clips, which can move in guide grooves in the side walls of the mounting box, in its longitudinal direction, and whose clip part can be pulled in between supporting walls of a retaining space so that the hook projections of the cable duct are gripped in a clamping manner. In this position, although the mounting box is fixed on one side to the cable duct, it can, however, be displaced in the direction of the strip-like hook projections. For final fixing, attachment screws can be tightened in the slide part of the sliding clips, as a result of which the clip parts can be firmly clamped against the hook projections on the cable duct.

Title: Device for washing and drying
Inventor: BAUS HEINZ GEORG
IPC: E03D9/08
Filed: 1981-03-06
Abstract: The invention relates to a device for washing and drying the lower body region, which device can be attached to a toilet or a bidet, having a fan for blowing air into the interior of the bowl and having a source of heat for heating the air. In a device of this type, there is the problem that, when the washing or cleaning operation has ended, due to the relatively cold air still present in the interior of the bowl of the toilet or the bidet, at the beginning of the drying process when the hot air fan is switched on, said cold air is blown onto the lower body region which is still wet. The underlying object of the invention is therefore to keep cold air away from the lower body region with little expenditure. According to the invention, it is proposed that the source of heat be arranged in a covering in the front side of a fastening frame facing the interior, that this covering have an opening assigned to the source of heat, through which opening the air of the fan passes into the interior of the bowl, and that the source of heat is switched on before the fan is switched on to preheat the air present in the interior of the bowl. <IMAGE>
