Patent DE-3916310-A1 (DE)
Inventor: BRACHMAN MARK L
IPC: A01N33/12
Filed: 1989-05-19
Abstract: A solution useful as a moistening agent for sealing items such as gummed envelopes is disclosed. The solution has 2 to 25 parts per million of a quaternary ammonium compound as an anti-microbial agent in water for preventing slime formation and quantities of the agent are limited to assure the surface tension of the moistening solution is not deleteriously affected.

Title: Web winding mechanism onto subsequent cores
Inventor: SCHNELL HEINRICH
IPC: B65H19/22
Filed: 1989-06-19
Abstract: The mechanism winds a continuous flexible web onto a further core to replace a full coil. A core sleeve feed brings an empty core into contact with the intake roller, in which position the web held taut between the full coil and the intake roller is partly wrapped round it. A roller rotates freely on a guide and is moved by the taut web to increase the wrap-round angle round the new core to more than 180 deg., while a blade parts off the web between it and the full coil. The leading end of the new web is folded and inserted from the top between the intake roller and the new core. A plate (9) on the guide (8) extends for the full roller (11) width and part-way round it, leaving a gap (4) in between, its leading edge (3) being parallel to the intake roller, and its outer face (31) guiding the new section of the web (10). In the end position of the guide the  angle round the empty core (50) is more than 240 deg., the plate leading edge clear of it and the intake roller in the radial direction by an amount equal to between 0.3 times and twice the dia. of the roller.

Title: Annular combustor for gas turbine
Inventor: DUBELL THOMAS L
IPC: F23R3/10
Filed: 1989-07-24
Abstract: The annular combustor for a gas turbine engine has an outer elongated annular liner, an elongated annular inner liner, a dome mounted at the forward end interconnecting the outer liner and the inner liner for defining with it a combustion chamber. A number of fuel nozzles are circumferentially spaced and mounted in the dome for feed fuel into the combustion chamber. The fuel nozzles includes air inlet openings for admitting air into the combustion chamber, a portion of the air inlet openings having a smaller opening than the remaining of the air inlet openings spanning the circumference defining a sector in the circumference with smaller openings than the remaining circumference of the annular combustion chamber. The annular combustor consists of a number of openings circumferentially spaced in the inner liner and the outer liner about a transverse plane defining a single-stage air admission, a portion of the single-stage air admission dimensioned to admit a lesser amount of air into the combustion chamber than the remaining openings of the single stage air admission. The portion of the air inlet openings and the portion of the single stage air admission define a sector in the combustor having an airflow distribution that creates a stable combustion zone even when the remaining portion of the combustor is unstable.

Patent DE-4105321-A1 (DE)
Inventor: SOERGEL GUENTER DIPL ING
IPC: B21B37/24
Filed: 1991-02-20
Abstract: A control system for controlling a hot and/or cold rolling process by means of a process control system which executes a predetermined rolling programme containing the initial and final dimensions, material data, roll temperatures, etc. has a master controller for controlling the set values of subordinate, preferably decoupled, individual control units for the variable operating parameters of the individual roll stands, e.g. rolling force, rotational speed, approach, etc. The set values of the control units are calculated using model equations in which processed and statistically treated values of the processing parameters are substituted, with convergent adaptation of absolute parameters to the actual parameters. In the event of changes in requirements on the rolling process, in particular changeover from manual to automatic operation, changes in final thickness and/or changes in temperature, relative adaptation of the parameters is carried out based on the set values used before the changes in requirements.
