Title: Process and apparatus for the combustion of materials in a combustion chamber
Inventor: STEINER HANS-RUEDI
IPC: F23M5/08
Filed: 1982-08-14
Abstract: The grate is bounded on both sides by an end wall (22) which is made up of air chambers (20) with a closed flow space (30). The flow space (30) is covered on the combustion chamber side by the end wall (22) and a partition (27). The space formed in between is filled with a fibre material (28). The flow space (30) represents a defined flow channel with a substituted inlet and outlet opening (32,34) in which forced throughflow occurs of the cool air flowing into the combustion chamber. The outlet opening (34) has a slot-shaped channel (34a) which is inclined relative to the end wall (22). A coherent air curtain at a relatively high air temperature is produced at the end wall (22) due to the forced flow of air in the air chamber (20) and due to the outlet, inclined relative to the end wall (22), of the air from the air chamber (20), which air curtain contains an excess of oxygen with which the CO gases in the flue gases are completely oxidised to CO2. <IMAGE>

Title: Device for supporting two brake pedals
Inventor: HAAR LUCAS
IPC: B60T7/04
Filed: 1982-09-16
Abstract: The invention is based on a device for supporting two brake pedals (6, 7) for a steering brake system with two separately or jointly actuable master cylinders (1, 2), in which the brake pedals (6, 7) are supported next to one another on a common shaft (12) and a locking element (17) can be made to engage with the brake pedals (6, 7), which element in one position permits an independent pedal movement and in another position fixes the relative position of the brake pedals (6, 7). In order to obtain the same pedal movements in normal and in steering brake operation the invention proposes that the brake pedals (6, 7) be connected to one another by a rigid rotation guide (14, 15) on that side of the shaft (12) opposite the points of application of the master cylinders (1, 2), that the rotation guide (14, 15) be adapted for fixed mounting and that the brake pedals (6, 7) be freely movable on the shaft counter to the direction of support. <IMAGE>

Title: Yielding roadway casing
Inventor: KETTERER KLAUS DIPL ING
IPC: E21D11/14
Filed: 1982-10-01
Abstract: Excavated spaces in mining and tunnelling which are additionally stressed by the working are secured with a roadway support system which consists of rigid steel arches and sealing lagging as well as of a backfilling designed so as to yield as a unit. In this arrangement, a plastic or virtually plastic, non-setting material, such as clay, loam or a mixture of lime sand and oil or bitumen, is used as the backfilling. By providing escape cavities in the seam or in the rock or by suitable openings in the lagging, the plastic material can escape if excess pressure occurs, so that always roughly the same resistance is applied by the roadway support system overall. The steel arches have the cross-section necessary or required after completion of the convergence, which cross-section does not vary during the life of the roadway due to the introduction of the yielding capacity into the backfilling. <IMAGE>

Title: Circuit arrangement for PLL speed control, with automatic setting of the operating point
Inventor: MOEBIUS RICHARD DIPL ING
IPC: H02P23/18
Filed: 1982-12-01
Abstract: The invention relates to a circuit arrangement for PLL speed control, with automatic setting of the operating point, especially for electronically commutated motors in cassette drive mechanisms. The object of the invention is to find a circuit arrangement for PLL speed control in which the optimum operating point for the phase-difference signal is set automatically when running on no-load or basic load. This is achieved according to the invention in that the actual speed value is formed from the sum of the rectified generator voltage and a voltage which is proportional to phase difference, the static speed deviation in the locked state of the phase control loop is, furthermore, zero, and hence the e.m.f. supplied by a generator coupled to the motor, or the motor e.m.f. itself, is used as a reference voltage, making use of an analog memory.

Title: Circuit arrangement for detecting the grey-scale distribution of a digitised image
Inventor: KRAFT HANS RAINER DR ING
IPC: G06T1/20
Filed: 1982-11-30
Abstract: This method and the circuit arrangement developed for this method provides for the direct detection and determination of the grey-scale distribution of a digitised image. The application of the method is not only restricted to the evaluation of an entire image pattern matrix which is provided by a pick-up system (direct processing) but stored image matrices can also be processed in various read-out modes (total-frame-, area-, region- and object-oriented). This method makes it possible to use a multiplicity of image-analysis methods, for example automatic threshold control (threshold selection) or the determination of statistical textual features in the object-oriented read-out mode. In the method according to the invention, the rapid evaluation is effected by the use of the numeric grey-scale values of the individual pixels as address values for a fast storage matrix. In this matrix, each grey-scale value represents one storage cell which contains, for example, one 16-bit data word. This data word is incremented by one, beginning at zero, with each response of a cell, associated with the grey-scale value, within the transfer time of one pixel by a "read modify write cycle" with the aid of a fast programmable counter. At the end of a processing cycle, the number of grey-scale values is detected in individual planes. The image processing computer can access these data by switching the address and data lines.

Title: Hydraulically actuable appliance for the mechanical disintegration of rock
Inventor: PORSFELD FRIEDHELM
IPC: E21C37/04
Filed: 1982-07-30
Abstract: Hydraulic appliance for the mechanical disintegration of rock, having a cylinder (1), in which a hydraulically actuable piston with a piston rod (3) is arranged so as to be longitudinally movable. Fastened to the free lower end of the piston rod (3) is a sliding wedge (18) which acts on thrust jaws (17) which are connected to a cylinder lower part (2) which are insertable into boreholes, laterally displaceable to a limited extent and releasably connected by means of reinforced head pieces (32) to the cylinder block or to a cylinder lower part (2) arranged releasably on this and which have a slope corresponding to the inclination of the sliding wedge (18). The thrust jaws (17) are suspended in the cylinder block or cylinder lower part (2) on diametrically arranged transverse bolts (10) and are fixed and centred elastically by means of spring elements (13, 24). To adjust the working piston and therefore the sliding wedge (18), the working cylinder can be preceded by a hydraulic control unit (35), by means of which the pressure medium serving for advancing the working piston can be introduced in a vibrating manner into the working cylinder on the side of the working piston facing away from the sliding wedge (18). A comparatively higher splitting capacity is thereby achieved, at the same time with the working piston being subjected to less pressure. <IMAGE>
