Patent DE-4027021-A1 (DE)
Inventor: BARTELS ROBERT-JAN
IPC: B25D9/26
Filed: 1990-08-27
Abstract: In order to prevent overstressing of the transmission elements (drill sleeve and insertion end) when using percussion drilling devices, especially for drilling anchor holes, it is proposed to equip the pressure line (24) for the supply of the drive medium to the percussion piston (3) with a first control member (25) which reduces the working pressure driving the percussion piston - after a limit value of the rotary-mechanism working pressure is exceeded - as the latter rises. In addition, there is a second control member (42), via which the push-out pressure against which the percussion piston (3) can be returned counter to the percussion direction (arrow 21) can be changed, after a limit value has been exceeded, as a function of the size of one of the working pressures - namely of the percussion-mechanism or rotary-mechanism working pressure - in such a way that the size of the push-out pressure increases or decreases with increasing working pressure.

Title: Cleaning fluid filters by low pressure filtrate reverse flow - using turntable mounted rinser rotated by drive unit and drawing filtrate from inlet
Inventor: ROTT WILLI
IPC: B01D29/46
Filed: 1990-09-22
Abstract: Banks of fluid filters are cleaned by reverse filtrate flow which require a large pressure differential and complex arrangements. The filter cells are arranged in a circle within the filter housing. Filter cells are cleansed either singly or in groups by reverse filtrate flow from a turntable-mounted rinser rotated by a drive unit and drawing filtrate from an inlet, connected to an outlet. The filter cells are coupled at their outlet side when cleaning is in progress so that fluid may pass from one cell outlet to another. USE/ADVANTAGE - The arrangement facilitates the construction of a relatively simple assembly having a filter which may be cleaned using a low differential between the reverse fluid flow and atmospheric pressure.

Patent DE-4101980-A1 (DE)
Inventor: MERTENS FERDINAND DIPL ING
IPC: H05B41/16
Filed: 1991-01-24
Abstract: The ballast has two switches (S1, S2) which are connected to the AC supply in series and can be operated inversely with respect to one another. A series circuit consisting of an inductor (L) and a discharge lamp (EL) is connected to this switch arrangement. The discharge lamp (EL) is shorted out by a third switch (S3). As long as the amplitude of the supply voltage (UN) is less than a limiting value, the third switch (S3) is switched on and off a plurality of times within one half cycle of the supply voltage, with the first switch (S1) turned on. In this way, it is achieved that, in those regions of the half cycle in which the lamp would normally be extinguished because the supply voltage is not adequate, a sufficiently high voltage for lamp operation is made available by the inductor (L). The power transferred during one half cycle of the lamp can be varied corresponding to a desired power curve by varying the duty cycle of the pulses. <IMAGE>
