Patent DE-3038957-A1 (DE)
Inventor: SCHAERMELI KURT
IPC: F16L3/12
Filed: 1980-10-15
Abstract: The apparatus, for example a contact sensor (10), has a housing (19) which is formed by a housing lower part (21) and the cover (23). The clamping means (31) of the attachment device (13) for attaching the apparatus (10) to a pipeline (15) are arranged in the interior of the housing (19). The strip (11) having the clamping means (31) can initially be placed around the pipeline (15), the clamping means (31) then being pushed into a recess (29) which has slots (51) for the strip (11). Tightening the screw (43) reduces the size of the strip loop (45) and attaches the housing lower part (21) securely to the pipeline (15). After the remaining end (38) of the strip (11) has been cut off, the cover (23) is attached to the lower part (21) by means of a snap-action device (25). This cover (23) also avoids the risk of people injuring themselves on ends of the strip projecting from the clamping means (31). Since the apparatus (10) and the clamping means (31) are located on the same side of the pipeline (15), installation is considerably simplified. <IMAGE>

Patent DE-3110793-A1 (DE)
Title: Combined three-phase, gas-insulated electrical device
Inventor: TAKEUTI SUSUMI
IPC: H02G5/06
Filed: 1981-03-19
Abstract: A combined three-phase, gas-insulated busbar is disclosed which includes at least one eddy-current conductor which is used to pass on the eddy current which is produced as a secondary effect by the current which flows through high-voltage conductors, in order to avoid difficulties which arise from a recently observed phenomenon comprising the temperature of an externally sealed housing being increased by the eddy current. This eddy-current conductor consists of a material having good electrical conductivity, for example aluminium or copper. Even if the diameter of the sealed housing is reduced to such an extent that difficulties arise as a consequence of the temperature increase as a result of the eddy current flowing, the intensity of the eddy current can be reduced and, in the most favourable case, it is possible to overcome the eddy current completely so that a sealed housing can be used which is produced from cheap mild steel. <IMAGE>

Patent DE-3126419-A1 (DE)
Title: Furnace installation for straw or similar material
Inventor: SIMONIS JUERGEN
IPC: F23G7/10
Filed: 1981-07-04
Abstract: In a furnace installation for straw or similar material, a fuel string (43) made of compressed short straw is inserted into a cylindrical combustion chamber (18) and burned. The combustion chamber (18) has three different nozzle sets for selective combustion air supply:   a) two first nozzles (35) are arranged close to the fuel inlet opening (30) in the combustion chamber jacket. These blow the fuel string front side intensively; b) in the central chamber region, the air supply takes place through a set of second nozzles (38) which are arranged in the combustion chamber bottom (20) on both sides of the vertical central axis plane. The air flows from the bottom through the fire bed (44) and forms above this two powerful turbulent flows which bring about a good mixing of the volatile components with combustion air and thus intensive combustion; c) in the top (21) of the exit-side combustion chamber region, a radially downwardly directed set of third nozzles (41) for residual gas combustion is arranged. Additionally, the combustion chamber cross-section decreases in the fuel advance direction (22), which supports the swirl formation and forces the especially hot combustion gases in the upper region of the combustion chamber onto the fire bed which sinks with continuing combustion.   <IMAGE>

Patent DE-3145071-A1 (DE)
Title: Vibration damper for pile driving
Inventor: MENKHOFF KARLHEINZ
IPC: E02D9/02
Filed: 1981-11-13
Abstract: When drawing piles, sheet pile walls, etc., the pull rope on which the pile hammer or vibrator hangs must always be tight. But so that the vibrations which result from the striking are not transmitted via the tight rope into the jib of the crane, a vibration damper must hang between the pile driver and the rope hook. This patent application reveals a vibration damper which converts the tensile forces into lateral forces via an adjustable triangle of forces.
Patent DE-3150421-A1 (DE)
Title: Constructional unit, consisting of a hollow body which can be closed in an air-tight and vapour-tight manner by walls and rigid or movable closing bodies
Inventor: BECKER OTTO ALFRED DR
IPC: E04B2/74
Filed: 1981-12-19
Abstract: The subject matter of this supplementary application is further examples of application which explain the purpose for which the released molecular forces can be applied and the manner in which they can be applied. By their nature, these molecular forces only act over short distances. The object of the invention is therefore to apply and translate the virtually unlimited molecular forces in such a way that - depending on requirement - they come into effect over long working distances. This can be done, for example, by transmitting the forces from a drive element to pressure cylinders (pressure elements) of very much larger diameter which in turn put a liquid, in particular water or oil, under extreme compressive stress. This liquid is fed at its high pressure into supply tanks for utilisation at any time. Thus machines, e.g. water turbines for generating current, can be operated with a powerful output. The pressure liquid can be converted into vapour of corresponding pressure, and this vapour can serve to actuate machines, e.g. steam turbines. Another example of application relates to tunnelling. Here, too, it is necessary, in order to protect the tunnel charges driven into the rock from collapse, to insert supporting elements of high bearing capacity and to exert an opposing stress with them. Thus the original equilibrium of the rock masses which was destroyed by the forcing-open of the tunnel is restored. Specially designed rock anchors are also used for this purpose. <IMAGE>

Provision is made for the gearing (3) to be a reduction gear unit which greatly reduces the speed of the saw-blade shaft (9) carrying the saw blade (1) and deflects the drive force from the motor shaft to the saw-blade shaft (9) by an angle of, for example, 90 DEG , and for the saw-blade shaft (9) to carry at least one circular roller or disc (10) which is interchangeably mounted coaxially on it and serves to guide the tool and the diameter of which is less than the diameter of the saw blade. <IMAGE>
Patent DE-3208557-A1 (DE)
Title: Device for indicating values determined by electric pulses
Inventor: MILLER GERT
IPC: B67D7/08
Filed: 1982-03-10
Abstract: The invention relates to a device for indicating values determined by electric pulses, particularly during the delivery of fluid or gaseous fuels at filling stations. The device has a converter, for example an analogue/digital converter, which is used for conditioning the electric pulses to be supplied to a value memory, and a display device which is preferably formed by using LCD display elements. To prevent the appearance of incorrect display values, particularly due to low temperatures or high rates of change in values, a buffer memory is arranged between the value memory and the display device, which can be controlled by a control element connected to a temperature sensor and to a value-change detector. The control is effected in such a manner that, when the temperature decreases, and on depending on the rate of change in values, either a numerical pattern which conveys the impression of a continuously changing number appears on the display device or the least-significant digits are masked out while the display is changing.

Patent DE-3226094-A1 (DE)
Title: Recuperative heat exchanger
IPC: F24F13/30
Filed: 1982-07-13
Abstract: The invention relates to a recuperative heat exchanger for recovering heat from exhaust air, in particular in agricultural installations. Because of the specific conditions in agricultural installations, the exhaust air is frequently contaminated in the most common types of recuperative plate heat exchangers. The heat exchange values are depressed by the attachment of particles of dirt to the hot side of the heat exchange surfaces. Even the air ducts, which are kept as small as possible, can frequently be flooded by condensed water. It is therefore necessary to develop a recuperative plate heat exchanger which does not have the characteristics described above which impair the heat exchange, and is as efficient as possible in the prescribed conditions. It is guaranteed by means of the special design of the SDP heat exchanger which has two types of ducts that the heat exchange is optimised and, thanks to a cleaning system and to more rapid removal of the thermal condensate, ensures that the thermal resistance is diminished as far as possible.

Title: Cam- and pneumatically-controlled palper blower
Inventor: PRESCHER DIETER
IPC: B65H1/18
Filed: 1982-09-21
Abstract: The cam- and pneumatically-controlled palper blower is provided for sheet separators in feeders of, for example, printing presses. The aim of the invention is to improve such palper blowers in general, and particularly as regards their maintenance, and to allow them to be interchanged rapidly without complication. In addition, it should be possible to regulate the holding force of the palper blower on the sheet stack independently of the speed of the press and of the stream of blowing air for blowing the underside of the sheets. According to the invention, a pneumatic cylinder is arranged insertably in a housing which can be pivoted about a fixed axis, and the blowing air is fed directly from the air diffuser to the blower. The pneumatic cylinder is insertable from below, can be locked by means of a resilient pin which can also be in the form of a shearing element, and the elements for displaying the height position are fixed underneath the pneumatic cylinder on the piston rod. The field of application is limited to sheet separators of feeding machines. <IMAGE>

Title: Multi-circuit pressure-medium brake system II
Inventor: HUEBL EWALD DIPL ING
IPC: B60T8/36
Filed: 1982-10-30
Abstract: Multi-circuit pressure-medium brake system having at least one pressure-control valve, arranged ahead of the brake cylinders, and a pressure source, there being arranged in the transitional area of effect of the control circuits present, of which there are at least two, an active electric switching means in the form of a 3/2-way solenoid valve, which during proper operation subjects the relay valve to the analog pressure control of an analog pilot valve having a power-proportional or displacement-proportional pressure output. In the event of failure of the electrical supply, the active switching means changes over to the second, pneumatic control circuit. Due to further main valves, which can be connected to the pressure output of the relay valve and are themselves subject to pilot control by solenoid valves, the system can be extended to a single-channel or multi-channel processing of ABS control functions. <IMAGE>
