Patent DE-4207353-A1 (DE)
Inventor: BEUTNER WOLFGANG
IPC: B23B27/00
Filed: 1992-03-05
Abstract: The most varied designs of tool holders are known linked by a coupling device to a tool holder receptacle in order to define the tool holder both from moving in the axial direction and from rotating. Given the many components required for the coupling device, such tool holders are not only very costly but also prone to failure. In order to achieve a quick tool exchange without having to carry out machine corrections and to obtain a large range of applications, a tool holder (1) has a guiding part in its central area, is provided in this area with a guide (4) and with a guiding groove (5) which cooperate with a groove and with a clamping wedge (9) in the tool holder receptacle, and has at its lower end (11) a shaft (3) with a longitudinal locking portion delimited at its rear side by a longitudinal seat. A movable clamping jaw (15) engages the longitudinal locking portion (13). These tool holders, when placedtogether in machining magazines, are particularly suitable for revolver or CNC turning machines, as well as for milling heads.

Patent DE-4300235-A1 (DE)
Title: Lime kiln
Inventor: HOELTJE WILLI DIPL ING
IPC: F27B17/00
Filed: 1993-01-07
Abstract: The limestone kiln has a burning zone in two facing, stepped and angled burning planes with two preheating shafts. The heat feed for decarbonating is fed either at the side or pref. from above through the suspended cover into the V-shaped burning zone.Air does not flow through the further acid removal zone (E), between the burning zone (D) and the cooling zone (F), for the kiln pressure to be controlled at the hot gas exhaust, so that the underpressure at the hot gas outlet of the burning zone (D) is equal to the underpressure at the cooling air extraction in the cooling zone (F). The underpressure at the kiln outlet from the burning zone (D) is controlled by flaps for gas and cooling air fans at equal to or less than 0 mm water column, and pref. 0 to -10 mm water column, to minimise the entry of false air at the sliding table passage through the kiln wall. The sliding movement of the material at the angled banks of the burning zone (D) is restrained by hollow box carriers in front of the sliding tables, to prevent downwards settling.

IPC: B60G17/08
Filed: 1993-02-02
Abstract: The device is based on a two-body oscillator model with a linear bodywork spring in parallel with linearly estimated passive residual damping between the masses of a body and wheel. Analogue signals from body and wheel accelerometers pass through anti-aliasing filters before being digitised.The digital equivs. are band-limited and integrated to obtain speed signals for weighted addn. (g1,g2) into a desired damping force (Fsoll), while a difference signal establishes the current in the damping valve. Absolute values of wheel and bodywork speeds are added for determn. of the adjustment current (istell).

Title: Gas-fired water heater
Inventor: DANIEL WALTER DIPL ING
IPC: F24H1/00
Filed: 1993-02-27
Abstract: In known water heaters of the generic type, the NOx concentration in the combustion gases is reduced by the arrangement of cooling bars downstream of the burner openings. This measure does not however lead to the desired success in all cases. With the design of the water heater according to the invention, the staying time of the hot combustion gases in the burn-out section (18) is shortened and thereby the formation of NOx in the combustion gases counteracted. The residual content of CO is reduced to a permissible value by an oxidation-type catalytic converter (24) arranged downstream of the first heat exchanger (20). Preferred applications are gas-fired water heaters for hot-water heating systems and/or domestic hot water provision. <IMAGE>

Title: Method for controlling the switching-off process (turning-off process, disconnection process) in the strands of a reluctance motor
Inventor: ORTHMANN REINHARD DR ING
IPC: H02P25/08
Filed: 1993-04-30
Abstract: In the case of a method for controlling the turning-off process in the strands of a reluctance motor whose stator is provided with windings to which current pulses are fed in an impressed manner, said current pulses being calculated in accordance with a predetermined algorithm, as a function of the angular position and rotation speed of the rotor, the strand through which current is passing is turned off at a turning-off angle (vp) after the reference angle for the zero crossing (v0). In this case, it is necessary to distinguish between two operating regions which are called the "chop" region and block-voltage region. The invention provides that the turning-off angle (vp) is calculated using the same algorithm, and is set by a controller, for both operating ranges of the reluctance motor. In this case, a pulse-width-modulated voltage is applied to the live strand in the low rotation speed range, the "chop" range, and a constant voltage is applied in the upper range, the block-voltage range. The turning-off angle is calculated from the motor parameters and the actual operating variable in both ranges, subject to the condition that the torque yield is maximised and that the turning-off process is produced by the conversion of these variables into a turning-off pulse which turns off the live strand. <IMAGE>

Patent DE-4320011-A1 (DE)
Title: Two-stroke engine
Inventor: KURPIERS CHRISTIAN
IPC: F02B25/04
Filed: 1993-06-17
Abstract: The invention relates to a piston combustion engine having at least one cylinder, this having the object of using the air which has been compressed by the piston movement in the crankshaft housing for performing work and for cooling the engine. According to the invention, this is achieved in that the crankshaft housing has an intake valve (9) for controlling an intake duct (23), by way of which air, which is compressed by the cylinder moving down, flows into the crankshaft housing and flows out by way of the outlet duct (16), controlled by means of the outlet valve (10), in order to drive a turbocharger (15) which effects the supercharging of the cylinder. If the piston combustion engine operates with a plurality of cylinders, then it additionally has means which are in the form of sliding bearings or radial-shaft sealing rings and prevent the pressure compensation between the sections of the crankshaft housing which are formed thereby. The air flowing through the crankshaft housing additionally assumes heat-dissipating functions, as a result of which the necessary cooling performance of the cooling system can be reduced in comparison with conventional piston combustion engines. <IMAGE>
