Title: Flat-chamber heat exchanger and method and device for producing it
Inventor: SCHMITT LOTHAR
IPC: B23K11/00
Filed: 1983-01-03
Abstract: In a flat-chamber heat exchanger having two parallel metal plates which are held at a distance from one another by at least one insertion element, accompanied by the formation of an interspace, and are connected to one another on at least one side, is intended to be economic and simple to produce while having a high output. 
<??>For this purpose, spacer discs (4, 4h) determining the distance (i, h) between the two metal plates (1, 5; 24, 25) are distributed with a pitch (t, y) and welded to the two metal surfaces (2) facing one another. Moreover, the metal plates can, with the formation of different cross-sections of the interspace, be corrugated or be provided with at least one shoulder-like step, so that the interspace is stepped at different levels. 
<??>A device for producing this flat-chamber heat exchanger provides for the metal plates (1, 5) guided at a distance (i) from one another a movement path which is arranged - inclined at an angle (w) to the horizontal (H) - between electrodes (11, 12), a strand of a belt (14) which is assigned outside the movement path of the metal plates to a magazine or the like running in the interspace (6) between the metal plates.

Title: Method for testing the operating state of brakes
Inventor: STUMPE WERNER
IPC: G01L5/28
Filed: 1983-01-08
Abstract: A method for testing the operating state of brakes with brake linings subject to wear is described in which, in order to determine and display the brake lining wear on the individual wheel brakes for each brake actuation, the brake cylinder lift is measured and the smallest in each case of a number of measured lift values is determined and stored. The stored data are used as criterion for the status display. At the same time the amounts of wear are advantageously added up and visually displayed so that at any time the total amount of wear and hence the residual thickness of the brake lining can be determined. <IMAGE>

Inventor: HENNEBERGER HEINZ DIPL ING
IPC: G01J1/42
Filed: 1983-08-10
Abstract: A hand exposure meter for photographic purposes having a measuring element and an arithmetic unit, display means for the measured variables, a printed circuit board with switching elements for the measuring element and/or arithmetic unit in a housing, preferably having a battery compartment, the arithmetic unit having a potentiometer which can be adjusted from outside by means of an adjusting disc, is to be improved such that while retaining the outside dimensions additional space is provided in the device for accommodating further switching elements on the printed circuit board, and assembly is facilitated.

Patent DE-3331130-A1 (DE)
Title: Machine tool
Inventor: MIYAKAWA EIJI
IPC: B23B41/00
Filed: 1983-08-30
Abstract: This is preferably designed as a multi-spindle machine. Marking, boring, broaching and welding work and similar operations can be carried out with it. It contains drive rods (6), in particular drive shafts, spindles (10) with holders for the tools, springs (19) which are arranged between the spindles (10) and the drive rods (6) and continuously thrust the spindles forwards, spindle sockets (17) which cover the springs, and proximity switches (21) for detecting a return movement of the sockets (17). If markings, for example, are to be made on a workpiece (H), the machine body (1) is moved forward at high speed until the points of drills (20) bear against the workpiece. The proximity switches (21) are activated at the end of this movement, as a result of which the machine body is switched over to return movement. Consequently, only the spring force of the springs acts on the workpiece. However, this pressure only acts for a short time, beginning with the bearing of the drill points against the workpiece and ending with the activation of the proximity switches (21), whereby a marking operation is achieved. <IMAGE>

Patent DE-3338126-A1 (DE)
Title: Gas-fired heat exchanger, especially for absorption refrigerators
Inventor: SCHMUKER FRANZ
IPC: F23D99/00
Filed: 1983-10-20
Abstract: The heat exchanger has a vertically arranged premixing burner (22) constructed like a grate and having an array of holes (86), between the gas-outlet openings (45), to feed secondary air to the flame roots. The respective total cross-section of the holes (86) in relation to a surface element of the burner (22) decreases in the vertical direction of the burner from the top to the bottom such that, in spite of the thermal buoyancy of the combustion gases, a uniform intake of secondary air takes place over the entire height of the burner (22). It can be ensured by a corresponding dimensioning of the holes (86) and arrangement of the plane in which the holes (86) open, in relation to the plane of the gas-outlet openings (45), that the stream pulses of the inflowing secondary air are aligned parallel to the burner flames, so that the furnace efficiency is likewise improved and the pollutant fraction in the combustion gases is reduced. <IMAGE>

Title: Device for controlling filling elements in filling machines
Inventor: URBAN FRIEDRICH
IPC: B67C3/28
Filed: 1983-11-14
Abstract: The invention is used in filling machines for pouring liquids under counterpressure into bottles and relates to the control of filling elements with control stars for gas and liquid, switching means in the engagement area of the control stars and centring devices which are mounted on the filling elements which are raisable and lowerable by means of the bottles to be filled and are provided with bridges.

Abstract: The invention relates to a variable building scaffolding with working platform and scaffolding uprights which can be fitted together, it being possible for a multipurpose scaffolding of this type to have been achieved with a simple and cost-effective construction and easy transportability. In the case of upright parts which can be fitted in one another and connected by means of end bolts, in each case a deflection roller can thus be fitted on the upper upright end, via which roller a cable line can be led from the cable winch arranged on one side to the carriage provided on the other side for supporting a working platform, i.e. platform panels; with a double arrangement of such uprights. When erecting two such scaffolding sides with a corresponding spacing, the height-adjustable working platform can thus be arranged therebetween, for example with aluminium panels. <IMAGE>

Patent DE-3422591-A1 (DE)
Title: Electro-optical method for levelling
IPC: G01C15/06
Filed: 1984-06-18
Abstract: To prevent errors in the visual acquisition of the readings on the levelling staff and of the horizontal angle at the horizontal angle ocular, a restrictor which can be moved to both sides of the longitudinal axis is attached to the levelling staff, which is coupled to an electro-optical incremental scale and which is shifted to the top or bottom by such an amount that the zero marker on the restrictor corresponds to the aiming line of the levelling instrument in order to then output the digital measurement value of the staff to a computer. Because the levelling instrument is aligned with the levelling staff, the horizontal angle is at the same time also output in digital form to a computer by an electro-optical angle encoder. The horizontal distance is also determined in the same work cycle by the fact that on the restrictor a reflector is installed which reflects the measuring beam sent out by an electro-optical rangefinder mounted on the levelling instrument in order to output the linear distance thus obtained in digital form to a computer.

Title: Method for collecting refuse and refuse collection vehicle suitable for implementing the method
Inventor: GEISSELER HELMUT
IPC: B65F3/02
Filed: 1984-07-05
Abstract: The invention relates to a method for collecting refuse and a refuse collection vehicle for implementing the method. The known methods of this type have the disadvantage that the refuse collection vehicle has to stop for virtually every dustbin, and that a dustbin cannot gain access to the refuse collection vehicle until the previous dustbin has been emptied, put down and placed to one side. This results in disadvantageous waiting times and the expenditure of a large amount of energy due to the continual starting and stopping of the refuse collection vehicle. These disadvantages are avoided according to the invention in that the dustbins are successively received, emptied and put down again in a fully automatic fashion while the refuse collection vehicle is moving, the receiving, emptying and putting down of a plurality of dustbins being carried out in a temporally overlapping manner.
