Title: Burner/boiler combination with an improved burner and combustion process
Inventor: SCHNITZER LEO S
IPC: F23D9/00
Filed: 1981-01-23
Abstract: A compact burner/boiler combination (30) with a burner (10) is described. A liquid fuel (18) is gasified by the hot combustion products and forms a homogeneous fuel-gas/air mixture before combustion and leads to an essentially stoichiometric combustion of the fuel, thus resulting in a high speed and a very high flame temperature (approximately 4100 DEG F - 2100 DEG C); this leads to the splitting of some of the hydrocarbons into their basic elements, so that they are available for diffusive combustion. A small fraction of air is subsequently introduced tangentially (22) into the burner flame and generates the diffusive combustion of the free hydrogen and carbon produced by the combustion process and consequently a hot brilliant optimum flame formation with a high surface speed. Radiation and conduction bring about optimum heat transmission to the boiler heating surfaces. The sector of use of the invention is the generation of steam and/or hot water. <IMAGE>

Title: Apparatus for the production of metal granules
Inventor: KOPPATZ RUDOLF
IPC: B22F9/08
Filed: 1981-03-14
Abstract: An apparatus for the production of metal granules consists of a casting vessel with outlet openings in its base, through which the molten metal drips onto a moving support. In order to improve droplet formation and to ensure that neither preheating nor post-heating is required, the bottom of the vessel is of thin-walled design at least in the region of the outlet holes. As a result, the outlet holes are relatively short in relation to their length, allowing the molten metal to drip out without problems and eliminating the solidification of the molten metal in the holes.

Filed: 1981-04-09
Abstract: In the conventional circuits of this type, the control input is connected via a zero-voltage switch to a comparator which, in turn, is provided for driving an output transistor connected to the gate electrode of the triac. According to the invention, a combination of a digital component exhibiting three inputs and two outputs and an analog component exhibiting two comparators and another transistor is provided between the zero-voltage switch and the output transistor. A first signal input of the digital circuit section is controlled by the zero-voltage switch and a second signal output of this circuit section is provided for controlling the output transistor. The transistor of the analog circuit section is controlled by the first output of the digital circuit section. The output of this transistor, together with a constant current source, is connected to one input of each of the two comparators in the analog circuit section whilst a reference voltage is applied to the other input of the comparators. The second and the third signal input of the digital circuit section is controlled by in each case one of the two comparators. Finally, the digital circuit section is arranged in such a manner that when a L signal is present at the three inputs, its first signal output carries the level "L", its second signal output carries the level "H", whilst when the "H" level is simultaneously present at its three signal inputs, the first signal output carries the level "L" and the second signal output carries the level "H". The advantage of this circuit is that a minimum of external connections is required and that it has a wide range of applications.

Title: Device for the connection to a vehicle of at least one stabilizing strut for the lateral stabilization of the lower links of a three-point linkage
Inventor: SCHILLINGS DIETER
IPC: B60D1/30
Filed: 1982-02-25
Abstract: To achieve a kinematic length variability of stabilizing struts for the lateral stabilization of the lower links of a hydraulic three-point linkage on farm tractors or traction engines, without these needing to be changed over at the connection end or without bolts and retaining devices having to be changed over, the point of articulation of the stabilizing strut is guided on a circular path by a rocker mounted so as to be pivotable to a limited extent in a bearing block fastened to the tractor. The rocker can be locked in two end positions by bearing against one of two bearing faces terminating a guide face taking the form of a segment of a circle, with the result that two different initial positions of the stabilizing strut are obtained, so that the lower links can be set rigidly in the lateral direction in different pivoting positions. In one embodiment, the rocker is formed by two discs which are arranged rotatably on a bearing bolt and are connected to one another at a distance and of which the circular contour form is interrupted over less than half their circumference by congruent recesses which have the bearing faces for a retaining bolt in one of the two end positions. In another embodiment, the rocker is designed as a spring-loaded lever.

Title: Scissor-type lifting appliance for shaft rings
Inventor: PROBST ERNST
IPC: B66C1/56
Filed: 1982-04-16
Abstract: The scissor-type lifting appliance according to the invention has two telescopic tubes (1, 2), of which one can be fastened to a crane hook. Pivotably fastened to the periphery of the other tube (2) are lever arms (8) whose distal ends are each connected to a forcing beam (14). A device (16) transmitting a tensile force is connected on the one hand to one tube (1) above the lever arms (8) and on the other hand to a lever arm (8) and/or a forcing beam (14). By means of a further device (38-44; 38, 44, 41-54, 56-61), the possible displacement travel of the tubes (1, 2) relative to one another is changed in such a way that the forcing beams (14), during the lifting of the scissor-type lifting appliance, either move into a first position in which the forcing beams (14) bear against the inner surface of at least one shaft ring into which the scissor-type lifting appliance is inserted or move into a second position in which the forcing beams (14) do not bear against the inner surface of the shaft ring. <IMAGE>
Patent DE-3215425-A1 (DE)
Title: Steerable chassis, in particular for mobile cranes
IPC: B66C23/78
Filed: 1982-04-24
Abstract: To steer this chassis (4), direction-adjusting members (35) at the control console (33) are to be actuated when wheel drive devices (MV, MH) are disengaged, which direction-adjusting members (35) influence a logic control device (SE). After a direction-adjusting member (35) is actuated, the control device (SE) first sets the lifting devices (32) to extension of the supporting legs (30) and the locking devices (45) to release of the locked, pivotable wheel axles (10a, 10b). After this, servomotors (SMa, SMb) controlled by the control device (SE) set the pivotable wheel axles (10a, 10b) to the correct wheel position for the selected curve to be negotiated, and after the adjustment the locking devices (45) are set again for locking. An adjustment of the operating member (34) for controlling the wheel drive devices (MV, MH) from the zero position first of all, via the control device (SE), causes all supporting legs (30) to be retracted and power generators (22) to be set for release of the locked wheels (19a, 19b) which cannot be pivoted. Furthermore, the control device (SE) ensures that actuation of direction-adjusting members (35) is ineffective when the operating member (34) is actuated, and vice versa. With such a control system, inexperienced crane drivers can easily drive the chassis even on difficult terrain, and the risk of damage and accidents is substantially reduced. <IMAGE>
Patent DE-3215449-A1 (DE)
Title: Hot plate with edge protection
Inventor: KOENIG HANS
IPC: H05B3/74
Filed: 1982-04-24
Abstract: A hot plate, especially for laboratory apparatuses, has external circumferential edge protection which is at a distance from the edge of the hot plate. In consequence, the hot plate itself can be protected against shock and impact without this edge protection itself becoming so hot that a user could be burnt on it. Furthermore, relatively large production tolerances can be used and any spilled fluid can easily be removed from the relatively wide gap. The edge protection expediently includes a supporting frame which is located directly under the edge of the hot plate, supports the hot plate and, in addition, can protect the apparatus interior by means of a turned-down edge.
