Patent DE-3703452-A1 (DE)
Title: Scouring powdered material applied to filter - by rotating air blasts, to modify subsequent filtration properties
Inventor: BARNSTEDT DIETRICH
IPC: B01D46/00
Filed: 1987-02-05
Abstract: A set of parallel cylindrical filters separate dust from air drawn radially inwards from a dirty air compartment by a rotary blower. Accumulated dust is periodically detached by counter/lowing pressurised air emerging from a rotary blade inside each filter, with the filters pref. scoured in sequence while filtration is maintained with the remaining filters. Each internal blade is rotated by reaction from an emerging jet. After a scouring process the dusty air compartment briefly receives a charge of particulate material intended to adhere to the filter fabric. Such material may reduce filter mesh size (to enhance filtration effect) react chemically with one or more components of the dusty gas (esp. with poisonous components) or absorb part of the dust gas. If the gas being filtered contains glowing materials, a non-combustible inert substance can prevent the filter material burning. ADVANTAGE - Range of possible effective filtration processes is widened.

Title: Method for interrupting the drive activity, in particular rotary-drive activity, of a powered hand tool
Inventor: SCHMID WOLFGANG DIPL ING
IPC: B25D11/00
Filed: 1987-03-05
Abstract: A method for interrupting the rotary-drive activity of a hammer drill in the drive train to the tool (24) is proposed, in which a clutch (28), which is arranged in the drive train, is automatically disengaged as a function of an overload quantity. As overload quantity, a movement quantity of the hand-guided hammer drill in space is recorded and upon exceeding a preset value of this movement quantity the clutch (28) is automatically disengaged. The path and/or the speed and/or the acceleration of the hammer drill in space is/are recorded as movement quantity. This takes place via a rotation sensor (30) which causes the disengagement of the clutch mechanically directly or electromechanically indirectly via a control device. By pressing in an engaging actuator, the clutch can be re-engaged mechanically directly or electromechanically via a control device. The person working with the hammer drill in the hand is reliably protected from injury as a result of the apparatus being flung around in the event of blockage of the drill bit (Fig. 1). <IMAGE>

Title: Method for detecting small amounts of separable, light liquid pollutants contained in effluent, and appliance therefor
Inventor: DAUM WILFRIED DIPL ING
IPC: B01D17/02
Filed: 1987-11-24
Abstract: Separators for separating light liquids are known. They store the separated light liquid as a floating layer, and when a certain layer thickness, scanned by a probe, is reached, the light liquid is drawn off. In some cases, it is required to detect even the first occurrence of light liquid. The known probes cannot indicate such small layer thicknesses. In order to be able to detect even such small amounts of light liquid it is proposed to connect upstream of the separator a preseparation chamber having a small horizontal extent and to place the probe there. Thus even the small amount of floating material forms a layer thickness which can be sensed by the probe.

Title: Cleaning trolley for fresh and dirty laundry in hospitals and homes
Inventor: GOETZ ERNST
IPC: B62B3/00
Filed: 1988-02-10
Abstract: The cleaning trolley for fresh and dirty laundry in hospitals and homes, having hinged shelves, is used on one trip for storing and transporting fresh laundry with the shelves lying horizontally and on the other trip (return trip) for storing and transporting dirty laundry with the shelves standing vertically, great importance being attached to the support and operability of the shelves. The difficulty is to design the operation of the shelves in a simple and reliable manner, avoiding independent latches, catches, sliding bolts or the like which can be operated separately. As emerges for example from Figure 8, the shelf is mounted at its rear side on an articulated lever in a manner such that it can slide and pivot on both sides so that it can be brought from its horizontal position into the vertical position by being raised from its opposite front side support and then slid and pivoted into the vertical position so that the cleaning trolley is set up in a manner such that it can be loaded with dirty laundry for transportation to the laundry room.

Patent DE-3815421-A1 (DE)
Title: Method for switching a heat pump heating system
Inventor: KOERNER FRIEDHELM ING GRAD
IPC: F24D19/10
Filed: 1988-05-06
Abstract: In the case of a method for switching between two or more heating output levels of a heat pump heating system, the switching on of a heating output level depends on the actual temperature of the heating circuit and a delay time after the temperature has fallen below the desired temperature, which varies in line with a heating curve, of the heating circuit. In order to ensure that the heating output levels operate as long as possible, but at least one heating output level is switched off not simply after a specific delay period and not at a specific outside temperature, but in dependence on the current change in heat requirement, the differences in the values of the respective actual temperature and the respective desired temperature are determined at fixed intervals of time when the temperature falls below the desired temperature. Each differential value is respectively added to the previous differential value. When the sum of the differential values reaches a specific adjustable value, the heating output level is switched on. <IMAGE>

Patent DE-3901870-A1 (DE)
Title: Overhead conveying system
Inventor: ROLLMANN HERIBERT
IPC: B65G9/00
Filed: 1989-01-23
Abstract: If objects, such as trousers or the like, are to be conveyed in a clamped condition in known overhead conveying systems, conventional clamps are slid as additional items on to a conveying means which is already present. If a bunch of trousers are to be combined together in a single clamp and are to be processed one after the other, a depositing surface is used which is directly fastened to the work place and on which the trousers are folded when they have been fully processed. To accelerate the operating sequence and to improve the clamping action to permit objects to be processed while they are suspended, a conveying means is proposed which takes the form of a clamp and is composed of two rods which can be moved with respect to one another and are loaded with a clamping force. The clamp makes it possible to process the clamped parts following the "cascade principle", in which unnecessary operations and idle periods are avoided. The invention is especially well suited for the overhead manufacture of trousers.

Title: Method for data transfer between boards of an electronic circuit
Inventor: CORDELL STEVE DIPL ING
IPC: H05K1/14
Filed: 1989-03-17
Abstract: In circuits with removable boards, the conventional data transfer path is via a backplane system. The data rate is in this case limited in terms of bandwidth, the boards only fit into their corresponding board slots, and changes in the functions of the boards usually mean a corresponding change of the backplane. If, however, the transfer is carried out without a backplane via optical or electromagnetic paths, the transfer rate is considerably higher, and the positioning of the boards is no longer of any consequence.
