Filed: 1981-11-12
Abstract: A floor conveyor device with a platform and with displacement elements for holding and setting down heavy tools is described, which has an operating stand and drive and control units for the platform, the displacement elements and the mobile frame. The entire device is of essentially T-shaped construction in plan view and has an elongate drive and control component in which all the taller components and the driven wheels, in particular also the displacement elements and the operating stand are arranged. In the support part which protrudes at a right angle from said component constructed in the manner of a longitudinal member, only non-driven support rollers are mounted which are connected to one another hydraulically. This support part serves exclusively for bearing the platform which can thus be arranged at a very low position. Since all the wheels can be swivelled about vertical axes, the entire vehicle is very manoeuvrable and can be moved in the longitudinal direction of the drive and control part and also transversely thereto. Therefore, the new vehicle requires very little space for its application.

Title: Method for the numerical control of a machine tool
IPC: G05B19/41
Filed: 1982-12-06
Abstract: Methods for the numerical control of a machine tool use a machining program, for which purpose a computer for controlling the numerical control is allocated to the machine tool. A series of data for machining the workpiece is alternately transferred via the transfer channels between machine tool and computer. In the event of a circular path shape, tangential distances are calculated from the instantaneous circle-point coordinates, the lengths of which distances are limited in such a way that the tolerance band of the circle is reached again by means of a correction step of the size of an increment in the direction of the larger circle-point coordinates. The correction steps are carried out on the basis of a calculation which makes a statement as to whether the respective actual radius is larger or smaller than the desired radius. The calculation is based on the Pythagorean theorem. The correction steps are calculated by means of an iterative method.

Title: Mining method for seam-like deposits
Inventor: SPIES KLAUS PROF DR ING
IPC: E21C25/56
Filed: 1983-09-28
Abstract: The invention relates to a mining method for seam-like deposits, in which two gate roads (1, 2) used for the air supply, travelling, transporting materials and conveying the output are driven in the deposit parallel to one another at a considerable distance apart, between which gate roads (1, 2) the mining of the coal takes place at least at one longwall face which is advanced transversely to its longitudinal extent. In order to design a mining method of this type in such a way that it is more flexible and more readily adaptable to geological faults, the invention proposes that the face, formed as a short face (8, 9, 10), run parallel to the gate roads (1, 2), and that the mining of the section of the deposit located between the gate roads (1, 2) take place successively in strips, the length of which corresponds to the distance between the gate roads (1, 2) and the width of which corresponds to the length of the short face (8, 9, 10), the connection between the face (8, 9, 10) and the gate road (1, 2) being effected by mine-air and conveying passages (4, 5) which are driven merely in the seam thickness and run parallel to the gate roads (1, 2). The face equipment of the short face (8, 9, 10) is here moved into the corresponding accompanying passage (4, 5) of the gate road (1, 2) in each case at the end of the working of a headroom, is displaced there in its longitudinal axis by roughly its own length and is prepared for working the next headroom in the opposite direction. <IMAGE>

Title: Primer for application of leaf metal
Inventor: BRAUER PAUL H
IPC: C09D131/04
Filed: 1983-11-03
Abstract: Size gilding, due to the structure of the primer comprising a large number of layers of different compositions and the long drying times, is an inconvenient process which requires experienced specialists with considerable specialist knowledge. The invention has the object of preparing a bright gold primer which, as a ready-formulated coating composition, makes preparation of individual primers of varying composition by the user superfluous. This is achieved by means of a primer for application of leaf metal, in particular leaf gold or leaf silver, which contains, as binder, in addition to conventional fillers or pigments, a plasticiser-free aqueous dispersion of a thermoplastic having a film-formation temperature of from 4 to 15 DEG C and which dries to give a tack-free film.

Title: Process and arrangement for the fault-free welding of hollow profiles
Inventor: MUELLER VOLKER DR ING
IPC: B23K35/40
Filed: 1984-01-30
Abstract: The invention relates to a process and an arrangement for the fault-free welding of hollow profiles by means of an inner strand of material to form a circular cross-section or a cross-section differing from the circular shape, in which a metal band, for example copper or other refined ferrous metals, entering longitudinally is shaped to form a closed profile and is welded together at the edges. Profiles of this type are used as plated wires, heating conductors, welding electrodes, thermocouples or high-frequency cables. The aim and object of the invention is to increase the output capacity in that the enveloping tube is welded to the inner strand of material in continuous flow in a fault-free manner. The object is achieved in that the core wire 3 is deformed downwards in a large radius of curvature 5 in front of the profiling zone, and in the profiling zone is surrounded by a metal band 1 shaped to form a tube, with band edges extending longitudinally, then the cooling tube, whilst undergoing oval deformation, runs with reduced diameter through a welding apparatus which welds the enveloping tube in a known way to form a closed tube, and thereafter the pass for fitting close together is carried out. <IMAGE>
