Title: Stock-rod system for determining the burden level in a shaft furnace
Inventor: HERZOG INGO
IPC: F27B1/28
Filed: 1991-04-10
Granted: 1996-06-04
Abstract: The invention relates to a plummet device for determining the height of the charge in a blast furnace. The winding drum (1) for raising and lowering a rope (5) or a chain, to the end of which is attached a plummet (6), is driven by a hydromotor (3). The shaft of the winding drum (1) drives a displacement transducer (9). The motor used to drive the winding drum (1) is a so-called slow-running hydromotor (3). A signal which is matched to the respective measurement depth is transmitted by the displacement transducer (9) directly, i.e. without electric control, to a pressure-proportioning valve (10). At the hydromotor (3), this valve sets a plummet-holding pressure appropriate to the respective depth.

Title: Exchange control system using a multi-processor
Inventor: OSAKI YOSHIRO
IPC: H04Q11/04
Filed: 1991-08-19
Granted: 1997-09-16
Abstract: An exchange system which comprises a plurality of line setting processors and a line-setting-signal path management processor for connecting the line setting signal paths of lines to the plurality of line setting processors.  Each of the line setting processors judges whether or not the associated line is activated and when determining that the line is activated, informs the line-setting-signal path management processor of the fact.          The line-setting-signal path management processor determines, on the basis of the loads of the line setting processors, suitable one of the line setting processors to be connected to the line setting signal  paths of the activated line, and connects the suitable line setting processor to the line setting signal paths.  Communication of necessary data is carried out between the line-setting-signal path management processor and the plurality of line setting processors so that even when a new line setting processor is added in the system, a maintenance operator can avoid complicated load estimation.

Title: Water-filtered vacuum wall sander
Inventor: YARBROUGH GLEN ALLEN
IPC: B24B55/10
Filed: 1991-09-16
Granted: 2001-10-02
Abstract: ABSTRACT OF THE DISCLOSURE    Sanding apparatus in which dust raised by sanding is drawn by reduced pressure through a porous sanding sheet and directly through apertures into a plenum chamber and from there through an air passage into an air space in a closed container partially filled with water.  The air and dust are separated in the container by projecting the dust into the water from a small distance above it and, simultaneously, drawing the substantially dust-free air out of the air space by the reduced pressure so that the air does not need to enter the water.

Abstract: A product pricing system for supermarket shelf labels (14) comprises an electronic data transmission system which transmits pricing information to electronic shelf labels (14) by modulating a data information signal (33) in the electric supply to artificial lighting (13) in the environment of the labels. The labels have a solar cell (16) for providing operating power and a photodetector (15) for detecting the data information signal in the artificial light. The data contains address information and data relevant to pricing, storage and sale of items and is displayed by a shelf label LCD display (17). The modulation is by way of phase modulation in a central contol unit (12). Each module incorporates a rechargeable battery (18) and an adjustable timer for timing the interval between broadcasts to the particular module whereby the particular module is caused to flash its LCD display in the event that a broadcast is not received within a predetermined time to alert personnel of a possible fault in the module or system.

Title: Emergency exit window
Inventor: JAMES DAVID ROBERT
IPC: E05B65/10
Filed: 1992-05-13
Granted: 1995-08-22
Abstract: The invention relates to an emergency exit window for vehicles such as school buses.  Spring biased latches are carried by the upper part of a window pane.  The spring biased latches have bolts which engage stops at various locations on opposite sides of the window frame surrounding the window.  The latches may be normally operated individually by hand to raise and lower the window between a ventilating position (including half-open and other partially open positions),  and a fully closed position.   The window is equipped with an emergency handle which may be used to pull the latches towards each other, and thereby enable the window to assume a fully open position.  In the fully open position, inversion stops prevent the window from inadvertently closing in the event that the vehicle is overturned.  The latches are housed in a latch cover which has latch openings.  The latch openings are sized so that they prevent manual use of the latches to cause the window to be fully opened.  Therefore, only the emergency handle may be used to move the window to the fully open emergency position.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensi-tive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous materi-al to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vac-cum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are def-lected into the conduits of the papermaking belt by the vaccum pressure while the papermaking belt and the embryonic web travel over the vaccum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
