Patent EP-0275439-A1 (EP)
Inventor: SINNER ALFRED
IPC: F23N1/02
Filed: 1987-12-04
Abstract: Fuel-heated generators must work with a fuel/air ratio which is to be kept within narrow limits. With constant heating capacity, it is possible to add to a temporally constant quantity of fuel for this purpose a quantity of air, the flow rate of which can be kept constant by means of a blower. There is a requirement for generators, the heating capacity of which can be changed at least stepwise, despite use of such a simple device, for capacity adjustment. To increase the heating capacity stepwise, there is connected parallel to the main pipe (2) at least one secondary pipe (21), in which the same fuel/air mixture as in the main pipe is present, when the stipulated quantity of air is delivered in the main pipe. The preferred application of such devices is in generators for small central heating systems with water heating.

Abstract: Markings have to be applied to the surface (41) of a mineral fibre web (38), said markings being arranged transversely to its length or to its direction of movement. For this, a cylinder (1) is provided with peripheral heating zones, in the form of heating rods (26), corresponding in shape and position to the markings to be applied, said cylinder (1) rotating at a speed whereby the rods (26), or marking ribs (30) provided on the latter, effect the rolling essentially without any slippage on the surface (41) of the mineral fibre web (38). The heating rods (26) or marking strips (30) are made of metal and are electrically heated, by an internal tubular heating element (31), to such a temperature that when contact is made with the surface (41) of the mineral fibre web (38) a flat decomposition zone (43) is created which corresponds to the contour of the marking strips (30), in which zone the binder of the mineral fibre web (38) is decomposed and by changing colour produces the optically visible marking line. The cylinder (1) can be driven either by a d.c. motor synchronously with the line speed of the mineral fibre web (38), or it can also be driven by entrainment with the surface (41) of the mineral fibre web (38).

Abstract: Four-stroke reciprocating piston combustion engine with supercharging and method for the operation thereof, whereby at the end of the driving out stroke flushing air is supplied under high pressure for the driving out of residual combustion gas in the exhaust pipe. The pressure in the exhaust pipe (7) is kept higher than the pressure in the inlet pipe (6), and the flushing air is taken from a separate source of air under high pressure. A flushing air supply line (10) is provided with a flushing air valve (12) and connected with a source of air under high pressure, and control means for controlling the flushing air valve syn­chronously with the piston movement such that at the end of the driving out stroke the air valve is opened briefly while the exhaust valve is still just open.

Abstract: The invention relates to a sanitary unit having an automatic cleansing cycle. The unit comprises a lockable enclosure in which a partition defines a usage zone and a maintenance zone. A bowl is mounted for rotation between a utilization position in which it projects horizontally from the partition in said usage zone and a cleaning position in which it is tipped up into an opening in the partition so as to empty it into the maintenance zone. The upwards opening of the bowl is separated into two sections by a partition wall which extends upwardly to cooperate with the front walls of the bowl to form a rim surrounding the utilization section of the bowl. The bottom of the partition wall stops short of the base of the bowl to define an orifice and the rear section of the bowl forms an evacuation passage from the evacuation orifice rearwards to the maintenance zone when the bowl is tipped up.

Abstract: A vertical ballistic transistor (50) is described. Base metallic contacts (160) of reliable thickness are deposited on a carrier depletable layer (101) and diffuse into the base (120). A depletion region (200) forms in the depletable layer (101). The depletion region elec­trically isolates the base contact (160) from the emitter (103). The thickness of the depletable layer (101) prevents the generation of usual depletion regions in the base (120) that tend to cut off base current.
