Title: Method and circuit arrangements for suppressing unwelcome control actions in slip-controlled brake systems
Inventor: FENNEL HELMUT
IPC: B60T8/72
Filed: 1984-11-28
Abstract: In a method and a circuit configuration for suppressing unwelcome control actions in slip-controlled brake systems, which may be caused e.g. by oscillations of the axle, wherein the wheel rotational behaviour is determined and the braking pressure is controlled in dependence upon slip criteria and/or acceleration criteria, and wherein slip control will commence when predetermined threshold values (-bN) are exceeded, a threshold value decisive for initiation of the control will be varied in dependence upon re-acceleration of the controlled wheel. The re-acceleration may be continuously monitored and when it exceeds a predetermined limit value, the decisive threshold value is increased in dependence upon the magnitude of re-acceleration pursuant to a decay time function, and to thereby reduce temporarily the response sensitivity of control, that means the reaction threshold. The dependence on time can be predefined by an e-function, or a linear function will be chosen for the sake of simplicity. <IMAGE>

Title: Cable laying device and process
Inventor: MORGAN DR P H
IPC: H02G1/08
Filed: 1985-05-07
Abstract: A device for laying cables in a pipe comprises a brush having radially projecting stiff bristles 2, a swivel eye 7 centrally located on one face or end of the brush for attaching a rope thereto and, on an opposite face or end of the brush, means 5 for attaching one or more cables. The brush may be planar, similar to a chimney sweep's brush, or cylindrical, similar to a flue brush. The device, with the leading end of cable attached thereto, is drawn through the pipe by means of a rope attached to the swivel eye. The brush is of larger diameter than the internal diameter of the pipe so that the bristles are bent backwards (Fig. 4) against the interior wall of the pipe and so prevent or substantially reduce twisting of the cable in the laying process. The device is particularly advantageous when the pipe has cables in it already. <IMAGE>

Patent GB-896033-A (GB)
Abstract: 896,033. Measuring rotor unbalance electrically. HOFMANN, D. and HOFMANN, R. [trading as HOFMANN KOMM.-GES. GEB.]. June 13, 1958 [June 14, 1957], No. 19087/58. Addition to 860,847. Class 40(1). [Also in Group XL (c)] The invention is an improvement on the parent Specification wherein the unbalance of a rotor is measured by obtaining an A.C. signal indicative of the magnitude and phase of the unbalance at a frequency which is independent of the angular velocity of the test rotor, being preferably that of the main supply, e.g. 50 cycles, and is characterized by the addition of means for producing a variable phase, 50-cycle, reference voltage, comprising a rotor winding 14 (Fig. 1) mounted on the same shaft 6 as the test rotor 1 and located in the rotating A.C. field produced by a 3-phase stator 15, which is rotated together with the test rotor until the phase of its induced voltage coincides with that of the unbalance signal, when the rotor 1 is correctly located for removal of unbalance by a tool 3. The unbalance signal at 12 and the reference signal from winding 14 are squared and differentiated at 19, 20 respectively, and the pulses fed to a coincidence circuit 21, which energizes a relay 22 at coincidence to lock shaft 6 in this position, for tool 3 to remove material from rotor 1 at the appropriate position. The apparatus may be used for a two-plane balancing machine by removal of the unbalance in one plane as described above, and then rotating the winding 14 and a second tool 3 until the second unbalance signal coincides in phase with the reference signal.
