Abstract: A floor scrubbing machine (10) has scrub brushes (26) and their drive motors mounted in a scrub head (24) located amidships under the machine frame (11). Provision is made to move the scrub head laterally on occasion to a position where it extends beyond one side of the machine frame to facilitate scrubbing along walls, thereby eliminating the need for a scrubbing side brush. The scrub brushes bear evenly against the floor regardless of the lateral position of the scrub head even though a variable down force may be applied to the scrub head. The scrub head is resiliently attached to the means for moving it laterally so that if it encounters a solid obstacle while it is extended it will be yieldably pushed back under the machine frame with a minimum likelihood of damage, and then will automatically extend out again after the obstacle is past.

IPC: G05F3/26
Filed: 1990-09-10
Abstract: A current mirror circuit with master (T1) and slave bipolar transistors (T2, T3) has an insulated gate field effect transistor (FET) (M1) connected across the collector-base circuit of the master transistor (T1) to provide base compensation current for the various bipolar transistors (T1, T2, T3). The FET (M1) is scaled so that the collector-emitter voltage of the master transistor (T1) is set at a value at which it operates in the vicinity of its saturated region, and the collector-base voltages of the master (T1) and slave transistors (T2, T3) are generally equal. This results in an accurate mirroring of the master transistor (T1) current, while the current through the master transistor (T1) is itself preserved at the desired reference level because the FET (M1) does not draw any gate current away from the master transistor (T1).

Abstract: A rotating mass (3) drives an annular permanent magnet (18), transversely magnetised, which interacts with pole pieces (14c and 15c) of the armature (14 and 15) of the rotor (2) of a micro-generator, comprising, in addition, an annular magnet (12). This rotor interacts with a stator (1) comprising a winding (5) and armature pieces (6 and 7). When the magnetic force present between the drive magnet (18) and the rotor (2) overcomes the magnetic force present between the rotor (2) and the stator (1), the rotor "unlocks" suddenly and places itself in the position in which the diameter on which the two pole pieces (14c and 15c) are situated is parallel to the magnetic field of the magnet (18). In the course of this sudden movement of the rotor, an electrical current is produced. The mass (3) can turn in any direction and by any number of turns, in order to produce the current, the link between the magnet (18) and the rotor (2) comprising no limitation of the angular offsets of these two elements. <IMAGE>

Title: Device for holding screws during tightening
Inventor: PALM ERICH
IPC: B25B23/10
Filed: 1991-11-08
Abstract: A device for holding screws (2) during tightening can be fixed to the housing of a drive unit (4). A screw nut, which can be connected to the drive, serves to receive at least a part section of the drive end of a screw. Also provided are two support jaws (9, 10) which are pivotable transversely to the screwing-in axis (14) and in their rest position leave free a passage opening for the shaft (20) of the screw (2). In their rest position, which at the same time also represents the use position, the two support jaws (9, 10) are freely projecting from their rotary bearing (15, 16) to the screwing-in axis (14), aligned approximately transversely to the screwing-in axis (14). In the direction counter to the screwing-in direction (E), the support jaws (9, 10) are spring-loaded and pivotable in the screwing-in direction (14). The screws are thus held in two places arranged at a distance from one another, and more specifically on the one hand by the screw nut on the screw head and on the other hand by the support jaws (9, 10) on the screw shaft, so that even relatively long screws can be held safely, until the penetrating tip of the screws has bored into the workpiece. <IMAGE>

Abstract: A digital signal modulator modulates an input digital data code to a channel code which has more bits than that of the input data code. The digital signal modulator comprises an NRZI transformer and a modulator. The NRZI transformer NRZI-transforms an input channel code and the modulator then modulates the input data code into a channel code. The modulation is implemented by selection of a channel code so that the DSV converges to zero from two channel codes assigned in advance to each of input data codes. The above two channel codes have different polarities of CDS values after the NRZI transform. The channel code is defined so that the number of '1's in the channel code is odd if a value of the CDS equals zero after the NRZI transform.
