Title: Device for regulating the oxygen content in flue gases of furnaces
Inventor: WUEEST JOSEF DIPL PHYS
IPC: F23N1/02
Filed: 1987-04-09
Abstract: The device for monitoring an oxygen regulator, for a furnace with a closed-loop control and a control element that influences the ratio of fuel to combustion air, contains a noise generator (18) that periodically generates a fault signal which is fed into the signal paths of primary detectors (4, 5, 6, 7) generating controlled variables, and a noise-signal receiver (19) that monitors the occurrence of the periodical fault signals, and activates an alarm device (20) via a control logic circuit (14) if they do not occur. The control element influencing the ratio of fuel to combustion air, for example an air damper drive (2), is regulated by an oxygen regulator; however, if an oxygen measuring device (4) is not functioning, it is controlled by an air damper control (10) on the basis of the signal from an air-supply temperature sensor (7). <IMAGE>

Title: Method and drilling rig for producing underground transverse bores, in particular horizontal core bores for obtaining soil samples, from the surface
Inventor: SPARENBERG HEINRICH ING GRAD
IPC: E21B7/04
Filed: 1987-09-01
Abstract: A method of producing underground, horizontal core bores by means of a drilling rig on the surface. To this end, a vertical bore and then a deflection bore as well as an adjoining starting bore are made with a solid drill string. After the removal of the solid drill, a turbodrill with a core barrel on the one hand and a connecting rod on the other hand is attached to the solid drill string, in order to be able to make the first horizontal core bore. Then further core bores are made with the interposition in each case of a drill rod corresponding to the length of core travel between the solid drill string and the core drill string. The entire drill string is subdivided in practice into an active core drill string and a passive solid drill string, and in fact with considerable reduction in wear with regard to the solid drill string and a considerable reduction in the drive power with regard to the core drill string, which exhibits low wear in any case. <IMAGE>

Title: Method and device for testing running transparent webs
Inventor: SCHMIEDL ROLAND DIPL PHYS DR
IPC: G01N21/896
Filed: 1988-02-29
Abstract: In the testing of transparent material webs for ruptures extending essentially longitudinally in the web, a light beam proceeding from a point arranged alongside the running transparent web on one side or at a continuously varying acute angle is led over the width of the web, a projection plane being arranged underneath the web on which the flying light spot of the beam projects a scanning line which is detected by a photoelectric converter, converted into pulses and fed to the computer. If shadow tears appear in the projected scanning line, there is a reduction in intensity of the quantity of light falling on the photoelectric converter, while at the same time a reflection of light in the region already sampled occurs. In the event of this combination, an error signal is triggered. <IMAGE>

Title: Safety belt retractor with tightening device
Inventor: BUTENOP KLAUS
IPC: B60R22/46
Filed: 1988-03-23
Abstract: In the case of a safety belt retractor with a tightening device, being composed of a drive which is activated when the retractor is actuated, is arranged in the vicinity of the belt-winding shaft of the belt retractor and can be connected to the said shaft via a cable drive in the event of actuation, a locking element being eccentrically mounted on the pulley receiving the drive cable, being held in its rest position by the force of a spring and, in the event of actuation, being pivoted out radially until it engages in a toothing of a coupling part which is connected to the belt-winding shaft, a tooth-on-tooth position of the locking element and the assigned locking toothing is to be avoided. To achieve this, in order to permit the predefined deflection of the locking element (23), a control element (36) is provided which, in the event of actuation, before deflection of the locking element (23), is locked in an assigned control toothing (39, 27) and for the outwardly pivoted position of the locking element (23) to be fixed on the basis of its coupling to the latter. <IMAGE>

Title: Hydraulically actuated clamping element, in particular a clamping ring, for clamping tools or workpieces in position
Inventor: HEIZE GERHARD
IPC: F16B31/04
Filed: 1988-05-30
Abstract: Hydraulically actuated clamping elements, such as clamping rings seated on a spindle on which the clamping ring is supported axially in one direction by thread, bayonet or supporting ring and annular grooves and in which an annular cylinder space for accommodating an annular piston or several cylinder bores, distributed concentrically about the axis of rotation, for accommodating pistons are made, the annular piston or the pistons exerting a clamping pressure on the tool or a workpiece through the admission of pressure medium, and in which a non-return valve for maintaining the clamping pressure at the annular piston or the pistons and a pressure-relief valve are provided in the pressure-medium feed, have the disadvantage that the clamping pressure drops in the event of the slightest leakage. This is ruled out according to the invention owing to the fact that an accumulator cylinder (26) with spring-pressure-loaded accumulator pistons (27) arranged in it is connected to the pressure-medium feed between non-return valve and annular piston (25) or piston (5). <IMAGE>

Title: Process for starting the spinning of a polyamide yarn
Inventor: GERHARTZ SIEGMAR DIPL ING
IPC: B65H54/86
Filed: 1988-07-26
Abstract: In the course of the winding-up of a freshly spun polyamide yarn which comes from the spinneret, the first yarn layers tend to become detached in the course of the winding-up process. This does not happen when the yarn, before being placed on the bobbin centre, is taken off the spinneret at a high speed in such a way that its modulus of elasticity is greater than the ratio of winding-up take-off force and winding-up extension. With this it is taken into account that the polyamide yarn tends to swell and that the winding-up extension has to be determined after subtraction of the swelling.

Title: Elastic spacer ring for a grain arranged in a combustion chamber
Inventor: MOLL MANFRED DIPL ING
IPC: F02K9/36
Filed: 1988-11-26
Abstract: The invention relates to a solid propellant grain, which can be used to produce thrust in missiles or projectiles and which due to different temperature-dependent environmental conditions, for example in the case of extreme cold down to -40@C or high temperatures up to +60@C experiences a change in length, as a result of which the grain can be damaged during transport, for example due to a resulting longitudinal play. In order to prevent such damage the invention provides for defined fixing of the grain (16) in its assembly position inside a combustion chamber (12) by means of an elastically deformable spacer ring (20). The spacer ring (20) is equipped with flexible knobs which on the one hand do not jeopardise the ignition of the grain in the support area and on the other, can conform to the variations in the length of the grain under extreme cold and heat. In the example shown the spacer ring (20) is supported on the inside boundary surface (26) of the combustion chamber (12) and a combustion chamber cover (24). In a modified embodiment it can also be used as an outer ring bearing on the outside of the combustion chamber (12) and the combustion chamber cover (24) or as intermediate ring between two adjacent grains. <IMAGE>

Abstract: The invention relates to branched, thermoplastic polyamides (nylons) obtainable by hydrolytic polymerisation of  omega -aminocarboxylic acids and/or lactams. The proportion of polymer molecules having more than one branch is at least 50 % by weight, which is achieved by adding polycarboxylic acid and polyamine components which cause branching to the melt of the base monomers in a strictly defined molar ratio. These polyamides can be prepared batchwise over extended periods with good reproducibility and quality and have high resistance to flow.
