Patent DE-3235132-A1 (DE)
Title: Method of grinding saw-blade teeth and grinding machine for carrying out this method
Inventor: VOLLMER ERWIN HERMANN
IPC: B23D63/12
Filed: 1982-09-23
Abstract: In saw-tooth grinding machines, it was known to move the face-grinding side of only one grinding wheel up to the face and the back of a tooth by swivelling the wheelhead through large angles and then to finish-grind first of all the faces and then the backs of all teeth. It was also known to face-grind the face and back of a tooth one after the other, that is, to finish-grind each tooth, and in fact with machines either with two wheelheads or with two wheels arranged on the same axis on a common support. So that each tooth can be finish-ground with less effort, the tooth back is now ground with the periphery of the same grinding wheel when surface grinding the tooth face. To grind carbide inserts of the teeth, a diamond coating can be embedded on the wheel in such a way that sometimes its surface on the flat side of the wheel is working and sometimes its surface on the periphery of the wheel is working. The wheelhead need only be slightly adjustable in an angular manner in accordance with the inclination of the tooth back; it can be moved by compound-slide guideways in three axial directions spatially intersecting at right angles by means of hydraulic drives or electric servomotors which can be operated from a control panel. In addition, the wheel with its motor can be pivotable inside the wheelhead about an axis parallel to the wheelhead guide. <IMAGE>

Title: Underfeed stoker
Inventor: WIESER RUDOLF DR
IPC: F23K3/14
Filed: 1983-05-26
Abstract: The proposal relates to an underfeed stoker which has a substantially increased limit output as regards heat generation and an increased degree of mechanisation as regards the discharge of ash. The increase in heat generation is obtained on the one hand by the installation of two furnace troughs in a single-part or multi-part air box, and on the other hand by the extension and partial covering of them, the initiation of the ignition process of the fuel already taking place in the covered regions of the two furnace troughs. Such a kind of underfeed stoker is suitable for flame tube boilers of up to 12 tonnes/hour nominal steam production. It can also be arranged very satisfactorily in a separate, double-walled and water-cooled precombustion chamber of the boiler. The mechanical discharge of the ash takes place by means of conveyor screws of refractory material, which are arranged in channels. An embodiment of such an underfeed stoker with only one furnace trough is also possible, and is suitable for the equipment of flame tube boilers of up to 6 tonnes/hour nominal steam production. <IMAGE>

Title: Circuit arrangement for exchange of signalling between telephone switching systems interconnected as primary and secondary systems
Inventor: SCHOENE LOTHAR
IPC: H04M7/14
Filed: 1984-02-13
Abstract: In the circuit arrangement for exchange of signalling between telephone switching systems interconnected as primary and secondary systems, in particular PBX systems, on both sides of the secondary connection line within the line circuit connected thereto, in each case a ready-to-receive modem is linked using a four-wire connection via a hybrid circuit to the two-wire connection path. The signalling exchange itself is performed according to a frequency shift keying method recommended by the CCITT, a data word in each case being serially transmitted after the transmission of a send signal. The information contained in a data word of this type can be directly assigned to a feature so that a control device located in the line circuit can evaluate the data word in order to effect switching processes, the data word within the switching system concerned being further processed or temporarily stored. The ready-to-receive modems are in each case linked using a four-wire connection via a hybrid circuit to the two-wire connection path, this hybrid circuit being formed either by the switching of electronic switching points or by an active hybrid resistance circuit.

IPC: B64C31/028
Filed: 1984-06-22
Abstract: Wing tips for collapsible wings of small aircraft (hang-gliders and ultra-light aircraft having flexible wings). In the sail (so-called double sail), which is designed as a hollow body, the edge curve 7 is articulated on the side-tube end 3 and, with respect thereto, is connected in an articulated manner to an intrinsically folding support 8, such that, during dismantling of the aircraft, this support is folded into the intermediate space between the edge curve, which is then folded up, and the side tube. This central joint 12 is provided with a locking device. A smooth, curved boundary of the wing can thus be achieved in which all the parts are located in the sail without causing drag and no parts need to be separated, as a result of which the erection and dismantling times are reduced and erection defects are avoided. In addition, the complete surface which is surrounded by the edge curve and the support can be used as an aerodynamically effective mainplane dihedral setting. <IMAGE>
