Abstract: A recuperative tubular heat exchanger comprised of a 
plurality of tube-bundle heat exchange modules (20) stacked 
in a spaced array and interconnected by U-shaped, open-end 
header conduits (30) to form a serpentine flowpath through 
which a fluid to be heated is passed in heat exchange 
relationship with a heating fluid passing in cross flow over

Patent EP-0170351-A3 (EP)
IPC: A01B63/22
Filed: 1985-05-02
Abstract: A hydraulic actuator (26) raises and lowers an imple­
ment in response to a height sensor acting through a spring 
(44) against one end of the spool of a four position spool 
valve (48). The other end of the spool is acted upon by a 
spring (78). At the correct height the spool assumes neutral 
position (A). Low and high deviations in height shift the 
spool to a slow raise position (B) and a slow lower position 
(C) respectively which provide for raising and lowering at a 
rate which is slow by virtue of a flow restriction (118). When 
the implement is raised to a transport position and the spring 
(44) is untensioned, the valve assumes a position (D) in 
which the flow restriction (118) is bypassed for rapid 
lowering of the implement. Lowering is prevented by a check 
valve (96) until a pressure line (54) to the valve is pressurized 
from a selector valve (50). Pressure in a branch line (107) 
then opens the check valve. The selector valve (50) has a fast 
raise position in which it reverses the connections to the 
spool valve. The pressure in what is normally the return line 
(56) is communicated by a branch line (126) to the same end 
of the spool as that acted upon by the spring (78) whereby 
the spool is forced into position (D) in which the slow 
restriction (118) is bypassed and the reversed connection 
raises the implement rapidly.

springs (42) are provided at opposite ends of the spool valve 
(34) for engagement with the pistons (30, 32) for switching 
over the spool valve (34) between the first and second 
positions in response to piston movement.

IPC: G01S11/10
Filed: 1987-06-16
Abstract: Windfinding apparatus is described in which receiver 
processing of the Global Positioning System (GPS) signals 
is without knowledge of the spread spectrum codes. The 
apparatus receiver ignores the bi-phase code and recovers 
the carrier frequency of all satellites in view of the 
receiving antenna. Two of these receivers are used in a 
windfinding system. One of the receivers (22) is located on 
the ground at a known latitude and longitude. The other 
receiver is placed on a weather balloon sonde (14) and launched 
into the atmosphere. A telemetry transmitter aboard the 
sonde transmits a signal that contains the GPS carrier 
frequency information to the ground-based telemetry 
receiver (17). The telemetry receiver output and the local 
codeless GPS receiver feed a set of tracking filters (20). The 
filtered signals are evaluated to obtain a measurement of 
the difference between the local GPS receiver carrier 
frequency and the sonde GPS receiver carrier frequency 
caused by the velocity of the sonde relative to the 
ground-based receiver (i.e., doppler effect). The wind 
velocity is computed based on knowledge of the doppler of 
the sonde GPS receiver and known GPS satellite positions. 
The sonde velocity is computed as a three dimensional 
vector. This vector can then be integrated to obtain the 
x distance, y distance and z altitude from the sonde 
launch point.
