Patent EP-0360101-A3 (EP)
IPC: B60H1/00
Filed: 1989-09-08
Abstract: A temperature control system (10) for a passenger van 
having individual temperature selection controls (60, 134) for 
passengers in the forward and rear sections of the passenger 
compartment. Separate exothermic heat exchangers (28, 100) 
for circulation of engine coolant therethrough are provided 
for the forward and rear passengers. Each heat exchanger is 
supplied by a coolant control valve (106, 26) and individual 
blowers (109, 42) provide a stream of forced air over the heat 
exchangers. A thermistor (148, 58) senses the temperature of 
the air discharge over each heat exchanger and a controller 
sums the sensed temperature signal with a user selected 
relative temperature reference signal provided independently 
by the forward and/or rear passenger selector inputs and a 
valve position signal; and, the controller generates a control 
signal proportional to the summation. An electrical actuator 
for each valve (50, 124) moves the valve until the sum is a 
null for controlling coolant flow to each heat exchanger to 
thereby regulate the discharge air temperature about the 
individually selected relative levels for the front and rear 
independently of the selected blower speed. Air conditioning 
evaporators (82, 152) may be disposed upstream of each of the 
heat exchangers; and, the thermistors sense the combined 
effect of heating and cooling and the system continues to 
modulate coolant flow to the heat exchangers for temperature 
regulation.

Patent EP-0391555-A3 (EP)
IPC: G11B25/04
Filed: 1990-03-15
Abstract: A recirculating filter system is provided for a sealed magnetic 
disk drive by providing a cartridge housing that mounts a filter medium 
closely adjoining the disk stack and substantially concentric therewith. 
The frame (39) that mounts the filter medium (37) also serves as a baffle 
or diverter to deflect air impelled by rotation of the disks to the rear 
of the filter medium. The remaining sides of the housing contact the 
cover or enclosure to define a dead box behind the filter medium wherein 
the velocity head of the air flow is converted to a potential head. Air 
impelled along the surface of the medium, at the side confronting the 
disk stack, provides some aspiration. A plenum formed at the radial 
outward side of the filter medium enables effective use of the entire 
medium surface. The recirculating air filter cartridge is not only 
compact within a corner of the cover or enclosure, but also is easily 
manufactured as a result of the simple filter medium configuration.

Title: Delay-based congestion avoidance in computer networks
Inventor: JAIN RAJENDRA K
IPC: H04L12/56
Filed: 1990-08-28
Abstract: A packet data communication system employs a congestion avoidance method in which each node measures the round-trip delay occurring when it sends data to a destination and receives an acknowledgement. This delay is measured for different load levels, and a comparison of these delays is used to determine whether to increase or decrease the load level. The load level can be adjusted by adjusting the window size (number pf packets sent in to the network) or by adjusting the packet rate (packets per unit time). The objective is operation at the knee in the throughput vs. traffic curve, so that the data throughput is high and the round trip delay is low. Control is accomplished at each node individually, without intervention by the router or server, so system overhead is not increased.

Title: Long-term leak monitoring device for double-walled containers, in particular double-walled container bottoms.
IPC: G01M3/16
Filed: 1994-05-19
Abstract: The invention relates to a device for the long-term leak monitoring of double-walled container systems, in particular double-walled tank bottoms, which permits, at low cost, the monitoring of, if appropriate, a multiplicity of double-walled tank bottoms cyclically or simultaneously with respect to the occurrence of leaks. By means of the device it can be established whether a leak has occurred in the outer bottom or in the intermediate bottom, the size of the leak and the location of the leak being able to be determined. According to the invention, an intermediate layer is applied to the inside of an outer bottom, the said intermediate layer serving to support the inner bottom. A sensor cable having a variable dielectric constant is laid in the intermediate layer, protected to a large extent. By means of the special intermediate layer, it is firstly possible to dissipate the forces acting on the tank bottoms and, besides, to lay the sensor cable at defined locations which are known in detail. In order to make possible a prescribed propagation of liquid, the intermediate layers have special recesses or are laid in such a manner that the liquid flow is not impeded. <IMAGE>
