Title: Automatic pile driver producing boreholes with reciprocating impact piston
Inventor: BALVE GERHARD
IPC: E21B4/14
Filed: 1995-08-23
Abstract: This automatic pile driver is sued to drive boreholes and has an impact piston (4) moving axially up and down, with a working volume (5) into which a guide tube (8) enters, the tube being fixed to the casing. The volume has radial control ports (3), whilst further radial control ports (13) penetrate the guide tube. A control sleeve (15,27) is guided in an annulus (11) of the guide tube. The guide tube (8) is formed by an inner- (9) and an outer tube (10). The inner tube (9) and the control sleeve have corresponding limit stops (22,23). The inner tube (9), the outer tube (10) and the control sleeve (15,27) have groups of radial control ports (13,14,17) coming into mutual correspondence during the forward or reverse strokes. The control sleeve is spring loaded (16). In the advancing position, the following are opened: a channel (20), allowing control air into the control sleeve (15) pressure chamber (19); and the inner tube (9) control port (13), into the control sleeve (15) chamber (18). The annulus (11) and the working volume (5) of the impact piston are connected by an axial hole (12). Controlling air and the compression spring (23) work in the same direction. In the annulus (11) ahead of the control sleeve (27) a control air channel (25,26) discharges into a pressure chamber (35). In an alternative arrangement, the control air and the compression spring (23) work in opposite directions. The outer tube has at least one externally-turned recess (24,40). The control sleeve (27) may be advanced and retracted without spring loading pressure chamber (18,34; 19,35) causing back and forth action.

Title: Discriminatory overcurrent detection and trip system for dc motor
Inventor: JO HYUN-MIN
IPC: G01R19/165
Filed: 1995-11-29
Abstract: An overcurrent detection/trip system for a DC motor (M) supplied from a source (VDC) via a control unit (10) and EM relay (20) converts the motor load current (IM) to an equivalent voltage (VS) across the resistor (RS) of the converter (30). The voltage (RS) is compared with a first reference voltage (Vvef1) in the integrator/comparator stage (40) and the integrated excess voltage (Vamp) is compared with a second reference voltage (Vvef2). In the event that the voltage (VS) is greater than (Vvef1) and the voltage (Vamp) is smaller than (Vvef2) a trip signal (RS) results in the switching off of the motor (M).

Title: Latent cold storage tank using vaporiser tubes
Inventor: FIEBACK KLAUS DR
IPC: F25D3/00
Filed: 1996-02-16
Abstract: The vaporising tubes (3,4) are spaced from each other within the storage tank (1) so as to lie close together at the tank inlet and diverge from here outwards. The cold carrier (7) enters the liquid area of the tank produced by the outside (15) of the solidified storage material (6) and the interior (14) of the tank itself so the diverging ends of the tubes lie in the liquid area specified. The tubes diverge at a fixed angle (ALPHA) and one tube extends as a branch tube. The tank is dimensioned to maintain a liquid phase between solidified material (6) and tank interior (14). In cold storage, the free ends (4') of the diverging tubes stand clear of the solidified material as the cold carrier here has pierced the ice wall in this part of the tube. These ends of the tube lie close (a) to the tank, appreciably nearer than at the tube end (3,3').

Patent DE-19648534-A1 (DE)
Title: Rotor flux orientated control method for asynchronous drive
Inventor: QUANG NGUYEN PHUNG DR ING
IPC: H02P21/18
Filed: 1996-11-24
Abstract: The method involves processing signals in a d-q coordinate system which rotates with the rotor flux. The actual value of the phase oriented stator current component isu, isv and isw are transformed to rotor flux oriented stator current components isd and isq. The transformed components are used as control components for an inner current regulation. The current regulator calculates the turn-on time of the operation voltage with respect to the phase from rotor flux oriented stator voltage components usd and usq as control variables and output values. The reference variables of the inner regulation are determined as regulation output of a flow regulation and as regulation output of a rotational speed regulation.  The rotor flux is determined as a regulation value for the flow regulation and a field angle is determined for the d-q coordinate transformation. The field angle is determined using a field model and angle calculation from the stator current components and a mechanical angular velocity. The mechanical angular velocity is determined from a stator current vector (is) and from a stator voltage vector (us) without a shaft encoder and is adaptive followed-up. The calculated angular velocity is used for the flow model and the angle calculation for the calculation of the rotor flux and the field angle and for the regulation value for the rotational speed regulation.
