Abstract: ABSTRACT            Process and apparatus for producing sponge iron or pig iron A process for producing sponge iron from iron ore is described, which is reduced to sponge iron in a reduction shaft furnace by means of a hot reduction gas.  For this purpose reduction gas at a temperature in the range 750 to 900°C is introduced into shaft furnace     level with bustle plane     having been produced in a gasifier then cooled and purified in a cyclone separator  .          Reduction gas is introduced below the bustle plane at a temperature below that of the reduction gas introduced in the bustle plane and is preferably introduced into the shaft furnace     between 650 and 750°C.      Increased carburization of the sponge iron is obtained.          Increased carbon separation also results through a volume increase, particularly by increasing the cross-section through the lower part of the shaft furnace.  Carburiza-tion is also assisted in that the ratio of the reduction gas quantity supplied below the bustle plane is made as large as possible compared with the reduction gas quantity supplied in the bustle plane.

Title: Floor treatment machine
Inventor: BRUNNER PETER
IPC: A47L11/14
Filed: 1988-03-09
Granted: 1991-01-15
Abstract: INVENTOR:  PETER BRUNNER          INVENTION: FLOOR TREATMENT MACHINE                        ABSTRACT OF THE DISCLOSURE     The machine housing is equipped with travel wheels and a control or manipulating handle.  A floor treatment or work implement has a central throughpassage and a treatment or working surface which, in the operating position of the floor treatment machine, bears with essentially its entire treatment surface upon the floor to be treated.  This floor treatment implement is rotatable by an electric motor mounted at the machine housing.  A steering wheel is disposed within the space bounded by the central throughpassage and the steering axis of this steering wheel substantially coincides with the rotational axis of the floor treatment implement. The steering wheel is displaceably mounted in the direction of its steering axis and is exposed to the action of a pressure spring element which presses the steering wheel against the floor.  To ensure that the floor treatment machine can be moved in random directions and that the floor treatment implement can be operated at high rotational speeds also with moderate motor power requirements, the travel wheels are lifted off the floor in the operating position of the floor treatment machine, while the steering wheel presses against the floor with a force which, except for a so-called residual weight or force, corresponds to the inherent weight of the floor treatment machine.  The residual weight or force produces a specific contact pressure of the floor treatment implement upon the floor which at most amounts to about 0.25 N/cm2.

Inventor: LINDENBAUM HERBERT
IPC: G01F15/075
Filed: 1988-03-30
Granted: 1994-05-03
Abstract: Abstract of the disclosure:   1.   Arrangement for flow measurement. 2.1  When mass flow measuring instruments are used, undesirably large measuring errors can occur when a heterogeneous two-phase mixture flows through the measuring instruments, for instance a fluid/gas mix-ture.  The new arrangement for fluid measurement is intended to reduce the measuring error during this time. 2.2  As soon and as long as a recognizable measuring error occurs in the measuring instrument, the signal of the latter is not analyzed but an artificially generated signal is fed to the analyzing system for this period.          Compared with the falsely measured mass flow of the measuring instrument, this artificially specified value is much closer to the actual mass flow.

Title: Shade operator
Inventor: WILK JOHN
IPC: E06B9/68
Filed: 1988-06-27
Granted: 1991-12-03
Abstract: ABSTRACT     A shade operator includes a drive unit having a central stud forming the axis of rotation for the shade roller. A manually operable pulley is mounted on the stud, and is engageable with a coil spring clutch member mounted about the stud coaxial with the pulley. The shade roller is engaged by a bushing which is also mounted for rotation on the stud. The bushing is provided with a projection which engages the clutch spring due to the weight of the shade and causes the spring to further grip the stud to prevent rotation. Operation of the pulley engages the spring such that its grip on the bushing is loosened, which allows the spring, bushing and shade roller to be driven by the pulley as desired to raise or lower the shade. Halting of pulley rotation allows the spring clutch to fully re-engage the stud to keep the shade at the new desired location.
