Patent DE-3139098-A1 (DE)
Title: Belt conveyor with starting tension station
Inventor: POHLE HELMUT
IPC: B65G23/44
Filed: 1981-10-01
Abstract: When belt conveyors are started, which in underground mining occurs frequently even during one shift, the bottom belt develops a sag which has to be compensated by means of a displaceably arranged tail drum acted upon by tensioning units. The time needed for this is substantially reduced by two tail drums being used which are arranged so as to be displaceable in opposite directions and are arranged in abuttingly connected frame structures. By reducing the time for catching the sagging belt, belt conveyors of any type are protected from blows by the sagging belt, the tensioning units of the displaceably arranged tail drums being correspondingly connected. <IMAGE>

Title: Process and co-current regenerative shaft furnace for burning limestone and similar mineral raw materials
Inventor: FUESSL ERWIN
IPC: C04B2/12
Filed: 1982-04-27
Abstract: The co-current regenerative shaft furnace has three shafts (1, 2, 3), of which the middle shaft (1) has twice the cross-section of the two outer shafts (2, 3). The shaft furnace is operated in a two-phase cycle, the middle shaft (1) being, in the first phase, the combustion shaft with the fuel fed through fuel lances (4) and the combustion air (5) being fed from above. The combustion gases formed are mixed with the cooling air (6) fed from below and passed through short overflows into the outer shafts (2, 3) and discharged upwards. In the second burning phase, the outer shafts (2, 3) are combustion shafts, and the middle shaft (1) is the discharge shaft. The arrangement of the shafts (1, 2, 3) in a row achieves very short overflows between the shafts, so that settling of dust is largely avoided. Since the overflows are restricted by the outer walls of the shafts, these are readily accessible through ports (11) in the outer walls. <IMAGE>

Patent DE-3220272-A1 (DE)
Title: Process for forming multilayer printed circuit boards
Inventor: SHIMAZAKI TAKESHI
IPC: H05K3/46
Filed: 1982-05-28
Abstract: In a process for forming a multilayer printed circuit board, in which a multiplicity of printed substrates, as a rule a current source/earth substrate and at least one signal substrate, are laminated one on top of the other to form a laminate structure. A prepreg board is disposed between every pair of adjacent substrates and the laminate structure is uniformly subjected to pressure to prevent the occurrence of cavities and is irradiated with microwave energy to produce heat in the prepreg board, as a result of which the resin contained in the prepreg board is cured. Each substrate may be a body obtained by joining a multiplicity of substrates. The laminate structure can be disposed between a pair of clamping plates which are suitable for transmitting microwave energy. The laminate structure is uniformly pressed and heated by the process mentioned. The process mentioned produces, at low pressure, a multilayer printed circuit board which does not contain any cavities and has a high dispositional accuracy. In addition, according to the invention, the processing time is shortened. <IMAGE>

Patent DE-3227079-A1 (DE)
Title: Rigid foam material and process for its manufacture
Inventor: ODLER IVAN PROF DR ING
IPC: C04B28/26
Filed: 1982-07-17
Abstract: This concerns a rigid foam material having a closed-cell binder framework which consists of a dried waterglass foam hardened by means of a fluate. Finely particulate additives such as expanded clays, silicate fillers and/or alumina cement can also have been added to the binder framework and likewise also fibre materials such as glassfibres and/or mineral fibres. To produce the rigid foam material, a waterglass solution, the fluate and, if appropriate, the further additives and fibre materials are mixed with an aqueous surfactant foam to give a homogeneous foam mixture which is dried after hardening. The rigid foam material has, at low bulk density and a correspondingly high insulating action, good strength and pronounced heat resistance, and it can be produced very inexpensively.

Patent DE-3239421-A1 (DE)
Title: Suspended sliding door
IPC: E05D15/06
Filed: 1982-10-25
Abstract: In suspended sliding doors, especially fire-proof sliding doors, which are equipped with a running mechanism consisting of a running rail and of a plurality of running rollers, there has hitherto been the problem of the lack of easy movement, above all where heavy doors are concerned. The invention solves this problem by arranging the running rail (5) on the door case (3), whilst the running track is formed by a series of running rollers (8) which are fastened individually to a building wall (2) by means of adjustable mountings (9). The adjustable mounting (9) consists of a base plate (10) fixedly mounted on the building wall (2) and of a fastening flange (11) which is mounted pivotably and lockably thereon and in which the axle (12) of the running roller (8) is guided adjustably. The running rail (5) consists of an essentially C-shaped sheet metal section (6) which can be formed as part of the door case (3) and which receives a steel rail (7) in its upper part. <IMAGE>

Title: Grinding, polishing and cutting-off wheel
Inventor: JARBY SVEN DR
IPC: B24D7/16
Filed: 1983-02-18
Abstract: This wheel is particularly suitable for dental work on teeth in the mouth of a patient, in that no metallic parts are exposed and the wheel (20) is mounted on the head (12) of the wheel adaptor (10) so as to be fixed in terms of rotation. The head (12) has a support disc (15), exhibiting a flat bearing surface (11), and a counter-holder (17) held at a distance therefrom by grooves (16). The grooves (16) engage behind the counter-holder (17). The hole (21) in the wheel (20) has the same contour lines with the same dimensions as the counter-holder (17) which can therefore be inserted into the hole (21) in a positive-locking manner. The straight groove floor (18) of the grooves (16) provides a bearing surface for the longitudinal edges (22, 23) of the hole (21). The wheel (20) is thus fixed in terms of rotation simply by pushing the counter-holder (17) through, and subsequently twisting it. The time-consuming selection of right- and left-handed threads or the force-fitting of plug-in elements, with the risk of injury to the dentist, is eliminated. Cost-effective manufacture of the wheel adaptor is possible by virtue of the fact that the head (12) can be moulded from plastic. <IMAGE>

Patent DE-3319854-A1 (DE)
Title: Bag-run guide in the feed housing of a bag-cutting device, if appropriate for partly emptied bags
IPC: B65B69/00
Filed: 1983-06-01
Abstract: The invention relates to the design of the bag-run guide in the feed housing of a cutting device for cutting bags, which contain loose material and which, if appropriate, are partly emptied, by means of upper and lower knives which are directed peripherally towards one another and engage into the directing chute and which cut the undamaged bag into strips of uniform width. As regards bags damaged as a result of transport, the thickness of the bag is reduced by means of the reduction in volume, so that a so-called "floppy bag" is obtained. In such a bag, the bag face resting on the feed base is cut, whilst the upper face, without being separated, can remain approximately in the size of the bottom area of the bag, thus leading to faults during the further run. As a solution, provision is made for the bottom (2) of a directing chute (3/3'), the said bottom being provided with passages for the knives (5), to be arranged in the feed housing (1) pivotably about a shaft (4) fastened on the entry side. The position of the bottom (2), inclined in the direction of the flowing-in region of the knives (5) in a load-dependent manner, is determined by a resilient element (6) supported directly or indirectly on the feed housing (1), in such a way that, irrespective of the weight or of the thickness of the bag dependent on this, the inclination of the bottom (2) is adjusted for a virtually identical depth of penetration of the upper and lower knives (5) into the bag. <IMAGE>

Title: Circuit arrangement for regulating the output voltage of a power supply apparatus
Inventor: ROEHL WOLFGANG
IPC: G05F1/571
Filed: 1983-06-16
Abstract: A circuit arrangement for regulating the output voltage of a power supply apparatus has a first circuit part (V7, V8, V9, C1) which detects a deviation of the output voltage from a desired value and emits a regulation signal. Furthermore, a second circuit part is provided which responds to an unacceptable voltage change and forms a protection device. A voltage value which occurs on the first circuit part and is characteristically increased and/or reduced in comparison with the regulation signal produced in normal operation is used for driving the second circuit part (V1, V2, V3, V4). The described circuit arrangement is suitable for power supply apparatuses in which stringent requirements are placed on the constancy of the output voltage and in which a deviation of the output voltage from the desired value is intended to lead to disconnection. An advantageous use is especially in intrinsically-safe power supply apparatuses, as are used underground in mining (Figure 2). <IMAGE>
