Patent EP-0278678-A3 (EP)
IPC: G01M3/26
Filed: 1988-02-04
Abstract: A method and apparatus for substantially eliminating 
measuring inaccuracies in a storage tank leak detection system (22) 
caused by temperature-induced volumetric changes in the stored 
fluid product (18) is described. In a preferred embodiment of the 
method, a limp bladder (34) is connected to an end of a pressure 
tube (24) having an inlet (30) and a substantially hollow core (32). The 
pressure tube (24) and the bladder (34) 
are filled with a medium (42) having 
a temperature coefficient substantially lower than the 
temperature coefficient of the fluid product. The pressure 
tube (24) and the bladder (34) are then supported in a substantially 
vertical manner in the storage tank (10) such that a first portion 
of the medium is supported in the bladder (34) in static 
equilibrium with respect to a second portion of the medium 
supported in the pressure tube (24). The large disparity between 
the temperature coefficients of the medium (42) and the fluid 
product (18) insures that temperature-induced volumetric changes in 
the fluid product do not vary the level of the medium in the 
pressure tube (24). Accordingly, variations in the medium level in 
the tube represent a true indication of leakage of the fluid 
product out of the storage tank or leakage of a foreign 
product into the storage tank (10).

Title: Multi-cavity melt distribution manifold
IPC: B29C45/00
Filed: 1991-12-16
Abstract: An injection molding manifold for distributing pressurized melt from a common inlet to thirty two outlets. The steel manifold has rear and forward plate portions which are integrally brazed together. The rear portion is drilled and plugged along a first transverse plane to provide the melt passage with branches from a common inlet portion to four intermediate portions. Four sets of matching grooves are machined in the joining faces of the rear and forward portions whereby each intermediate portion of the melt passage in turn branches along a second transverse plane to eight outlet portions, each leading to a cavity. The combination of the melt passage branching in several different directions in two different transverse planes with the second plane having different sets of curved portions allows the melt passage to have a large number of outlets while still having smoothly curved bends without having a leakage problem. <IMAGE>

Patent EP-0663531-A3 (EP)
Inventor: EBBING PETER F
IPC: F15B11/06
Filed: 1995-01-09
Abstract: A pneumatic circuit prolongs a pneumatic valve (20)
opening time using an accumulator with two quick exhaust
type valves (36, 46) in series while providing a rapid
valve closing time. This structure and method is self-contained
and amenable to retrofit in existing
installations without any external connections. Slow
opening is achieved by routing inlet gas pressure
simultaneously to an accumulator (51) and the operating
cylinder (21) of the valve to be opened. A tortuous piping
path (61, 36, 62, 63, 44, 46) and increased volume to be
pressurized due to the addition of the accumulator (51)
substantially reduces the isolation valve opening time,
thereby eliminating problems associated with quick opening
of a pneumatic valve. 
     When the pneumatic valve (20) needs to be closed
quickly, slight venting toward the inlet valve (29)
immediately causes the quick exhaust valves (36, 46) to
vent (39, 49) their downstream pressure. The accumulator
(51) then vents through its quick exhaust valve (46) while
separately the main quick exhaust valve (36) quickly vents
the air cylinder (21) of the pneumatic valve. Closing
times penalties of less than 50 milliseconds can be
achieved using this configuration and opening times can be
increased by adjusting the volume of the accumulator.

Inventor: GUGLIELMI FRANCO
IPC: H04B3/06
Filed: 1996-02-23
Abstract: The present invention relates to a method of fractionally
spaced adaptive equalization which allows the achievement of
the performances of the optimal linear receiver with a high
degree of stability of the control algorithms. 
     The technique is applicable to a generic communication
system. 
     The present method provides a fractionally spaced equalizer
which is perfectly stable and has a good convergence rate
without introducing any deterioration of the performances
with respect to the optimal receiver and with an extremely
low increase in the complexity of realization as compared to
the prior art techniques. The invention is based upon the
introduction of a whitening filter of the input signal to a
fractionally spaced equalizer stabilized with the tap-leakage
technique, where the withening filter is a device able to
make the power spectrum density of the signal - repeated with
a period equal to the reciprocal of the signalling interval -
constant.
