Title: Nitrogen oxide emission reduction from burners - adds flue gas to combustion air for primary, sub-stoichiometric combustion zone
Inventor: MICHELFELDER SIGFRID DR ING
IPC: F23C9/00
Filed: 1980-10-30
Abstract: The process for reducing nitrogen oxide emission, when burning nitrogen containing fuels in an enclosed furnace, applies to combustion involving a sub-stoichiometric primary combustion zone and a super-stoichiometric secondary one. Primary air enters through the burners while secondary air has volume regulated according to the load. The secondary air is introduced around each burner, so as to form the primary zone boundary before feeding the second zone and entering the flame envelope. The air for the sub-stoichiometric phase has recirculated, partially cooled, flue gas admixed to it at a rate of up to 50% of the primary air flow.

Title: Self-loading forage box with an apportioning device
Inventor: KRONE BERNARD
IPC: A01D90/10
Filed: 1981-01-14
Abstract: The invention relates to a self-loading forage box with continuous load-space walls at the sides and an apportioning device which is arranged at the end of the forage box and has one or more apportioning cylinders (drums). The rear boundary of the apportioning device and of the load space is provided by an appropriately designed tail flap, which is locked to the apportioning device and can be unlocked by means of switching elements by the driving and/or switch-on device or by the driven apportioning cylinder itself.

Title: Appliance heated by a gas-operated burner
Inventor: NIBELLE PIERRE DIPL KFM
IPC: F23D14/14
Filed: 1981-01-28
Abstract: Gas-heated appliance for heating a liquid or gaseous medium located in a space, such as, for example, a flow heater, boiler or air heater. The heating takes place by means of gas-jet burners with a ceramic burner plate, through the pores of which the gas flows from a mixing space and is burnt on the side of the burner plate facing away from the mixing space. The closed combustion space is limited by walls of the space, in which the medium to be heated is located, and receives the jets directly, the burner plates preferably being arranged vertically.

Filed: 1981-03-20
Abstract: A sensor cable consisting of sprung layers (1, 2) which are permeable to liquid, a conductor mesh (3) and a sprung flexible core (4, 5). As a result of this construction, the sensor cable is insensitive to mechanical damage, that is to say it is improbable that all the conductors of the mesh (3) will be cut through under the influence of, for example, a sharp object. <IMAGE>
Patent DE-3114082-A1 (DE)
Title: Roller shutter with slats consisting of plastic and/or metal
IPC: E06B9/165
Filed: 1981-04-08
Abstract: The invention relates to a roller shutter with slats which consist of plastic or a plastic/metal combination and have a hollow-chamber profile. In order to reduce the heat losses in the roller shutter/window region, said slats have already been provided, on their surface directed towards the window in question, with a layer which reflects infrared rays. This reflective layer is, however, easily damaged by mechanical influences when rolling up and unrolling the roller shutter and is, moreover, exposed to a high degree of soiling and corrosion. The invention proposes to provide a surface (25, 25'), which reflects infrared rays, on a band-type element (24, 24', 240) and to arrange at least one such band-type element in an upended manner and so that it is protected, in the hollow chamber or hollow chambers of each slat (10) of the roller shutter, in such a manner that, when the roller shutter has been unrolled, an essentially continuous, reflecting surface is provided opposite the window in question. The heat losses in the roller shutter/window region can be further reduced if the band-type elements (24, 24', 240) have, on their outwardly directed side, a surface (26, 26') which absorbs heat rays. The invention can be used for all roller shutters, the slats of which have a hollow-chamber profile and consist either of plastic or partly of plastic and metallic parts. <IMAGE>

Title: Process for producing printed circuit boards provided with conductor tracks and having metallic plated-through holes
Inventor: ACKERMANN DIETER ING GRAD
IPC: H05K1/02
Filed: 1981-05-27
Abstract: A process which combines the advantages of fine-line etching with conventional printed circuit board production processes is provided for producing printed circuit boards having metallic plated-through holes. Extremely fine conductor tracks are etched out on a fine-line side using high-resolution photoresist in a preliminary etching process. The through plating is done by the tenting process. The thickness of all the metallic areas is increased by electroplating before etching the coarse structures, the electrical connections to both sides of the printed circuit board needed for electroplating being made solely via the conductor track plated-through holes.

Title: Wide-necked seal for casks
Inventor: BEHRENS KARL-FRIEDRICH
IPC: B65D45/32
Filed: 1981-07-06
Abstract: The invention "wide-necked seal for casks" relates to hollow bodies made of plastic material with outer projections integrally formed on the cask neck and a lid which engages over the opening and is divided into segments in the outer region. The lid segments are locked in the sealing position underneath the neck projections by a clamping means. The aim is pursued of providing a liquid-tight seal which is resistant to high mechanical loads. The essential features of the invention are the association of each neck projection with one lid segment which receives the neck projection in an opening, and also the rectilinearly limited linking of the lid segments to the lid circumference. The support for the clamping means is formed by a lower, rib-shaped opening limitation and by outer segment tongues pointing upwards. The invention is used in the sphere of transport packages blow-moulded from plastic material and having a large opening cross section.

Patent DE-3143234-A1 (DE)
Title: Navigation method
Inventor: GIELEN HARALD DIPL-ING
IPC: G01C21/28
Filed: 1981-10-31
Abstract: The invention relates to a navigation method in which a course reference device, for example a course gyroscope, is used for determining the course angle of a vehicle, and a displacement sensor (1) and a vertical sensor (2) are used for sensing the deviation of the vertical axis of the vehicle from the vertical. Signals of these measuring instruments are supplied to a computer which processes these signals, carries out a correction and generates a position signal. According to the invention, the correction relating to the alarm signal is carried out by drawing conclusions relating to the surface of the roadway and thus to a wheel slip, from the vehicle movements, particularly the pitch and roll movements, and the displacement sensor signal is corrected in accordance with the magnitude of the slip. In an alternative solution, an acceleration signal  alpha s is derived from the displacement sensor signal and from the signal of the vertical reference, a signal  alpha N corresponding to the longitudinal acceleration of the vehicle is also formed. By comparing these two signals, the wheel slip of the vehicle can also be determined and thus the displacement sensor signal corrected. <IMAGE>

Title: Method for controlling a pneumatically driven annular striker
Inventor: MOLSNER HERMANN-DIETRICH
IPC: B25D9/00
Filed: 1981-12-09
Abstract: In a method for controlling a pneumatically driven annular striker, a piston (3) situated in a cylinder is moved back and forth from one cylinder space to the other by reversing the driving air via corresponding control members. In the striking direction of the piston (3), the air situated in said cylinder space (4) is pushed out of the latter until the piston (3) strikes the striking bush (6). In the return direction of the piston (3) its reversal of movement is brought about by a corresponding air cushion which builds up at the right time in the cylinder space (5) there. The control pulse for reversing the direction of movement of the piston (3) is derived from its working pressure. <IMAGE>
