Patent DE-4300981-A1 (DE)
Inventor: VIERTLER RAINER DIPL ING
IPC: H02M1/00
Filed: 1993-01-15
Abstract: A micro controller (MC) which is constructed as a pulse-width modulator changes the duty ratio (the modulation) of the pulse-width modulation output signal (MS) at a specific switching frequency, and drives the downstream push-pull stage (GS) in a time-delayed manner by means of at least one upper power switch and one lower power switch (LSO, LSU). The micro controller (MC) has three pulse-width modulation outputs (ports P1, P2, P3). The actual PWM output signal (MS) is emitted at the first output (P1). The modulation signal (MS) plus a dead time (MS + TZ) are emitted at the second output (P2) and fed to the lower power switch (LSU) as a drive signal (ASU). The dead time (TZ) is emitted at the third output (P3), the drive signal (ASO) for the upper power switch (LSO) being formed from the modulation signal (MS) and the inverted dead time (TZ) by subtraction (SUB). In the modulation limit region (modulation tending to 100% and 0%), the dead time (TZ) is reduced automatically and one power switch (LSU or LSO) is switched on continuously, while the other power switch (LSO or LSU) is switched off in the mean time. Beyond a specific modulation limit value, a "Power bit" (PB) is emitted regularly at a fourth output (P4) and produces 100% modulation. <IMAGE>

Title: Method and apparatus for taking gas and/or oil and/or water and/or solid samples during drilling operation
Inventor: GROTENDORST GERHARD
IPC: E21B49/08
Filed: 1993-06-05
Abstract: A method and an apparatus serves to take gas and/or oil and/or water and/or solid samples during the drilling operation, i.e. without withdrawing the drill column. According to this method, an annular plug of drillings is formed in the area of the liquid-sampling rod, provided the depth permits it, and packing is set in addition or even on its own, so that the area to be investigated is closed off completely from the in-situ mud column and the rock connected to it. Thus a quite specific sample can be taken, for which the mud in-situ in the drill column, for example, can be lowered to such an extent that the valves of the liquid-sampling rod open and water or other medium is forced in by the reservoir pressure. In particular during the use of a core-drilling column, oil or gas can be sampled during deep drilling in the area between core bit and reamer bit by the core-drilling column being raised. After the sampling, the core-drilling column is lowered again, as a result of which the area to be investigated is closed off again. Here, too, the packing is set beforehand and/or the annular plug is produced. The packing can be set without the column being lifted by compressed air being taken from a compressed-air reservoir integrated in the column. After the sampling, the packing is relieved and can be reactivated in a deeper borehole section in order to ... Original abstract incomplete. <IMAGE>

Title: Double-steel-tube structural part
Inventor: IMAI KATSUHIKO
IPC: E04B1/19
Filed: 1994-06-03
Abstract: Double-steel-tube structural part, comprising an outer steel tube (4) and an inner steel tube (5), the outer tube (4) being provided with a thin steel-tube portion (4B) and being arranged between two thick steel-tube portions (4A). The thickness (tA) of the thick portion (4A) is from 1.5 to 1.7 times more than the thickness (tB) of the thin portion (4B). The inner tube (5) is arranged such that it overlaps not only the thin portion (4B), but also the thick portion (4A). The inner tube (5) behaves in the manner of a flexurally rigid tube with respect to the outer tube (4), with the result that the outer tube (4) can deform plastically in the longitudinal direction as soon as an axially compressing force exceeds the yield strength of the outer tube (4). The deformation takes place in an axially symmetrical manner along the outer surface of the inner tube (5). A framework structure comprising such structural parts prevents immediate collapse if the building is exposed to a strong earthquake or the like; see Figure 1. <IMAGE>

Title: Method for controlling the operation of driving a cop-changing apparatus in a spinning machine
Inventor: YAKUSHI MAKOTO
IPC: D01H9/18
Filed: 1994-11-03
Abstract: A cop-changing apparatus is suitable for reducing the time required for executing a series of cop-changing operations. The apparatus has a take-off rod moved upwards and downwards by means of a pantograph mechanism which is adapted to be driven by a power cylinder which converts the rotation of a drive motor into reciprocating movements of a driveshaft. The pantograph mechanism is rotated about a driveshaft towards and away from a frame of the spinning machine. In accordance with output signals which are emitted by a rotary coding device, generating a signal indicating the order of magnitude of vertical displacements of the take-off rod, and sensors for recording the positions of the pantograph mechanism relative to the spinning machine, a computer controls the operation for driving the cop-changing apparatus. When the take-off rod assumes a predetermined position in the course of actuation either by the power cylinder or by the pantograph-mechanism rotation device, the actuation of the other one of the devices, that is to say the power cylinder or the pantograph-mechanism rotation device, is commenced when the take-off rod assumes a predetermined position, with the result that the vertical displacement of the take-off rod and a rotation of the pantograph mechanism are brought about simultaneously as a whole.
