Patent NO-167012-C (NO)
Inventor: SALAMON KLAUS
IPC: H01M4/84
Filed: 1986-07-18
Abstract: A casting mold for manufacturing grid plates for lead batteries makes use of easily interchangeable mold inserts for each half of a two-part, external metallic mold holder. The mold inserts are made of a highly porous microfiber nonwoven material, and render unnecessary the conventional cork-flour coating of casting molds due to good thermal insulating properties, high permeability to air and non-wettability by lead. The casting mold inserts are manufactured in a process which involves fixing of the nonwoven material with a curable binder either during or after shaping of the negative for the grid plate, so that the resulting parts assume a cardboard-like consistency.

Patent NO-174984-C (NO)
Inventor: BEGUN RALPH MURRAY
IPC: G06F12/08
Filed: 1989-04-18
Abstract: A microcomputer system includes a microprocessor, a cache memroy, and a cache controller all coupled to a local bus. The local bus is coupled to a sytem bus, connecting the remaining system components, through latches. When writing data, the microcomputer can perform a posted write to a unit on the system bus by writing the data into the latches and then, on receipt of a ready signal from the cache controller, continuing its operations without waiting for the data to pas to its destination. A problem arises if the data is posted to a unit with a data width less than that of the microprocessor. In this case, the data should be sent in multiple cycles, but the read signal is generated before the data width of the unit is known and the microprocessor then continues its operations and can not, therefore, transmit the data correctly. To solve this problem, a logic unit is added to monitor the ready signal and the output of a decoder which detects non-cacheable addresses (which are of data width different from the microprocessor data width). If a non-cacheable address is detected, the read signal from the cache controller through the logic unit is withheld from the microprocessor, which now waits to continue processing beyond the write until a ready signal is received from the addressed unit on the system bus.

Abstract: A suspension control system is designed to adjust suspension  characteristics  between  hard  and  soft  for bounding and rebounding stroke independently to each other. The system has a sensor means for monitoring speed of a vehicular body as a sprung mass for producing a vehicle body speed indicative signal,  which vehicle body speed indicative signal is variable of signal polarity depending upon the direction of vibration, and a sensor means for monitoring relative speed between the vehicular body and a vehicular wheel as an unsprung mass for producing a rela-tive speed indicative signal which is also variable of signal  polarity  depending  upon  direction  of  relative movement of the vehicular body and the vehicular wheel.  A control unit detects combination of signal polarities of the vehicle body speed indicative signal and the relative speed indicative signal for adjusting damping character-istics for bounding and rebounding vibration independently of each other and depending on the detected combination.

Abstract: A cover for an inflatable air bag is provided which has an upper portion adapted to break upon inflation of the air bag and a side portion which extends downwardly from the peripheral edge of the upper portion.  An insert is embedded in the cover and includes a flexible net and a flexible reinforcing band assembly.  The net includes a side portion embedded in the side portion of the cover and upper portions which are embedded in upper portions of the cover.   Coupling portions vertically couple the side portion of the net to the upper portions thereof.  The reinforcing band assembly includes a horizontal band which is coupled by for example sewing to the side portion of the net along the entire perimeter of the side portion of the net and vertical bands which are sewn to the horizontal band and to the side edges of the upper portion and/or the coupling portions of the net.   The vertical bands of the reinforcing band assembly are bent back at their lower ends so that the lower portions surround the horizontal band and are connected thereto.  Since the vertical bands are wrapped around and sewn to the horizontal band, forces which act on the vertical bands when the air bag is inflated are distributed to the horizontal band so that the strength of the cover is great enough to withstand tensile forces which act on the coupling portions of the net.

Filed: 1992-08-06
Granted: 1996-11-19
Abstract: A method and apparatus for distinctively and proportionally displaying windows on a computer display screen is disclosed.  The amount of time each of the windows presented to the display screen is active (also known as "in focus") is monitored. Upon receipt of a command from the user, the windows that were active a longer length of time are displayed more distinctively than windows that were active a shorter length of time.  More specifically, windows are displayed on the display screen having a window size proportional to the length of time each of the window were active.  For example, a window that was active 40% of the time will have a size that is 40% of the specified window tiling area. Windows that have not been active long enough to exceed a minimum window tiling threshold are displayed as icons outside of or under the specified window tiling area and are not included in the calculations of percentage of activity of the windows.
