Title: Fabric workpiece movement - has pivot bearing on a guide arm fixed to a further guide arm to give sliding on two axes with workpiece rotation
IPC: D05B11/00
Filed: 1990-02-12
Abstract: The guide mechanism to move an appts. round a contoured outline such as for sewing, basting or cutting textile workpieces, has a pivot bearing between the grip and the guide arm. A curved contour is achieved by a combined sliding action in the X- and Y-directions with a simultaneous rotation of the grip round the pivot bearing. The magnitude and the positioning of the sliding and swing movements are controlled by a programmable microprocessor. Pref. the pivot bearing has a rotary drive with its housing secured to the guide arm, and its drive shaft mounted to the grip. The pivot bearing assembly with the grip slides on a horizontal guide arm which slides horizontally at right angles to the sliding direction of the grip on a second horizontal guide arm. Spindle motors, or toothed belt drives, give the sliding movement of the grip in relation to the first guide arm and the sliding movement of the guide arm in relation to the second arm. The setting motor gives the swing movement to the grip. One guide arm is dimensioned to transfer the material from the entry to the delivery stations.  A further short guide arm to carry the pivot bearing can be fitted to the first guide arm, at right angles to it and with a sliding movement. The microprocessor determines the working speed of the sewing, basting or cutting machine synchronised with the advance speed of the workpiece. The appts. is a self-standing assembly next to the sewing, basting or cutting machine. ADVANTAGE - The loading on the connecting cables is reduced, through the workpiece rotation and, at the same time, the working cycle times are reduced.

Title: Combustion gas mass pulse modulation - uses overlay of harmonic mass pulse oscillation on the base value to improve heat transfer to material in a tunnel kiln
Inventor: LEISENBERG WOLFGANG PROF DR IN
IPC: F27B9/40
Filed: 1990-05-07
Abstract: To modulate the mass pulses in the combustion gas to a burner or gp. of burners in a tunnel kiln for the ceramic industry, a harmonic mass pulse oscillation is overlaid on the base value of the constant pulses or the pulses modulated with a low frequency.  This is at a higher frequency range, pref. in the resonance range of the combustion zone atmos. The separate base value of a burner, or gp. of burners, operating constantly or at a low frequency modulation, is overlaid with a synchronised higher frequency mass pulse oscillation which pref.  is at the range of the resonance frequency of the gas column of the tunnel kiln. The mass pulse of the combustion gas flow is modulated through modulation of the combustion gas flow and/or the oxygen carrier or by delay in the feedback of a pressure control or a feedback of the oscillation of the atmosphere in the tunnel kiln to a pressure control. The combustion gas flow can be modulated through a rotary diaphragm with an adjustable rotary speed. ADVANTAGE - The technique improves the transfer of heat from the atmosphere to the material being fired, by eliminating the effects of the mass pulses on the burner capacity and on the accuracy of the controlled temp.

Inventor: BECK ERHARD DIPL ING
IPC: B60T8/48
Filed: 1991-03-18
Abstract: The description relates to a braking device which can be used for regulating both the braking and drive slip. The braking slip is regulated on the recirculation principle, and during drive slip regulation an open system is installed. In order to use the same pump (10) in both cases, there is a valve system consisting of a first clack valve (16) and a second clack valve (17) allocated to the intake side of the pump. The opening pressure of the first clack valve (16) is greater than that of the second (17). Furthermore the admission pressure of the low-pressure store (9) is greater than the opening pressure of the first clack valve (16). The first clack valve (16) is operative during braking slip regulation and the second (17) during drive slip regulation. The changeover may be effected, for instance by the master cylinder pressure via a control line (18).
