Patent DE-3830681-A1 (DE)
Title: Refuse-collecting vehicle
Inventor: BEHLING HANS-JUERGEN
IPC: B65F3/02
Filed: 1988-09-09
Abstract: Refuse-collecting vehicle with a refuse-collecting container, which is situated on a chassis behind the driver's cab and has refuse-introducing equipment including a refuse-compaction device for pressing the refuse in a direction of action through an opening in the container into the refuse-collecting container. The direction of action of the refuse-compaction device runs obliquely from the front/bottom to the top/rear onto the ceiling wall of the refuse-collecting container, and in the region of the opening in the container a projection is provided on the bottom of the refuse-collecting container, by means of which the container opening is reduced in its cross-section. By virtue of the direction of action selected the refuse can already be compacted at an early stage against the ceiling wall in the region of the entire cross-section of the refuse-collecting container and, as a result, optimum utilisation of the entire volume of the refuse-collecting container is made possible. The projection on the bottom of the refuse-collecting container furthermore prevents undesirable emergence of the refuse through the container opening.

Title: Lamp post for portable lamps
Inventor: BERNAUER ERICH OSWALD
IPC: F21Y103/00
Filed: 1988-10-14
Abstract: The lamp post serves to fit portable lamps by simply plugging and holds these portable lamps reliably on a pivotable arm by means of double clamps so as to be continuously radially and axially displaceable, and is fitted by means of a mount to a standing post so as to be continuously radially and axially height-adjustable, which standing post is vertically held by a base which has a floor space which is as compact as possible but not bulky, and the specific weight in its design is sufficient to hold the lamp post with the plugged-on portable lamp in each continuously adjustable variation so as to be protected against falling over, so that an optimum workroom illumination is obtained without the need for manually holding the portable lamp, and that the portable lamp, after being used, can remain on the lamp post by pivoting away the pivoting arm in bar-shape in a space-saving and orderly manner.
Patent DE-3838914-A1 (DE)
Title: Valve
Inventor: STIEFEL HANS-PETER
IPC: F16K11/07
Filed: 1988-11-17
Abstract: In a known valve, a sealing element which is not exactly simple is provided to seal off a leakage path between a closing body and a valve housing and to seal off a further leakage path between the closing body and a valve spool. The production and quality control of this sealing element with its somewhat complex cross-sectional area are not without their problems. To allow a sealing element (50) with a geometrically simple cross-sectional area to be installed, a projection (72) is provided on a shoulder (70) of the valve spool (22). The projection (72) can be brought to rest against the sealing element (50). It is thus possible to shut off two leakage paths simultaneously with a single, uncomplicated sealing element (50). The valve is intended essentially for applications in which convenience of manufacture and high reliability as regards sealing are required simultaneously. The valve can, for example, be a metering and fuel distributor valve of a fuel injection system for internal combustion engines. <IMAGE>
Patent DE-3839214-A1 (DE)
Title: Method and apparatus for introducing metal melt into a slab mould
Inventor: GROTHE HORST
IPC: B22D41/50
Filed: 1988-11-19
Abstract: When introducing metal melt into a slab mould, particularly a thin-slab mould, via an immersion casting pipe, it is unavoidable that turbulence and backwaves will occur at the surface of the metal melt in the slab mould and these have a disadvantageous effect on the structure and the homogeneity of the metal slab. The turbulence in the metal melt also leads to increased wear to the immersion casting pipe and to the walls of the slab mould, thereby reducing the life of the casting pipe and of the mould. According to the invention, however, these disadvantages are avoided by virtue of the fact that the metal melt in the casting pipe (1) is deflected by a trough (7) in the bottom (6) of the casting pipe (1), being retarded to such an extent during this process that the metal melt emerges in a virtually laminar manner with a correspondingly greatly reduced speed into the slab mould from lateral openings (4, 5) in the wall (2, 3) of the casting pipe. <IMAGE>

Patent DE-3908866-A1 (DE)
Title: Data input device for a balancing machine
Inventor: CURCHOD DONALD B
IPC: G01M1/02
Filed: 1989-03-17
Abstract: The invention relates to a data input device for a dynamic balancing machine, with the aid of which a multiplicity of parameter values can be input by the operator in response to the carrying out of a simple manoeuvre. The data input device (19) has for this purpose an elongated guiding arm (21) which is supported pivotably on a rigid arm (20). An elongated shaft (24) is supported pivotably at right angles on the guiding arm (21). The upper end of the shaft (24) defines a reference point (29) in space. Elongated contact arms (31, 32) project laterally from the opposite sides of this reference point and, in each case, carry a sensor device (33) in the form of a microswitch on the free end. These microswitches serve for the automatic input of the information into a computing unit (18). The pivoting angles of the guiding arm and of the shaft are then converted in the computing unit into spatial points from which the parameters necessary for the balancing of the wheel can then be calculated. <IMAGE>

Title: Method for controlling the programme in a washing machine
Inventor: SCHAEFFERSMANN WILFRIED
IPC: D06F33/44
Filed: 1989-03-18
Abstract: In a method for controlling the programme in a washing machine, it should be possible for the quantities of water needed for the respective wash programme sections to be set by the programme control device as a function of the amount and the nature of the laundry and independently of the influence of varying pressure conditions in the mains. In the first programme part, the computer of the programme control device measures the switch-on times of the solenoid valve prior to a target level being reached and totals these times. This total of switch-on times is stored in a memory of the programme control device and is multiplied by a factor from a value table. The calculated value gives the respective valve switch-on time for the subsequent programme sections and rinse cycles. The method is suitable for washing machines in which it should be possible for the quantity of water needed for a programme section to be set taking into account the amount and the nature of the laundry as well as the water intake pressure and volume flow.
Patent DE-3910676-A1 (DE)
Title: Method and equipment for operating an air mass flowmeter
Inventor: LOESING KARL-HEINRICH DIPL ING
IPC: G01F1/696
Filed: 1989-04-03
Abstract: In a method and equipment for operating a heated air mass flowmeter washed around by the airstream, its operationally caused changes, such as depositions of dirt and aging, are deliberately accepted. For this purpose, under specific operating conditions, for example in the case of no airstream and defined electrical heating, the operating characteristics then present are detected as measuring characteristics which represent a measure for the operating condition of the air mass flowmeter at that time. From at least two measuring characteristics determined at different times, such as two in succession, a measuring deviation is determined which represents a measure of the intermediately occurring change of the air mass flowmeter. This measuring deviation is used, for example with the aid of an offset of a characteristic curve which specifies the relationship between the air mass flow and the respective operating characteristic, to carry out a suitable correction and thus to correct continuously the changes of the air mass flowmeter. By this means, measures directly influencing the air mass flowmeter, such as those for preventing soiling thereof, are not needed.
