Patent EP-0067740-A3 (EP)
IPC: B01D53/047
Filed: 1982-05-19
Abstract: The invention deals with a process and an apparatus for 
improving product gas recovery in a pressure swing adsorp­
tion system having at least three adsorbent beds.  
     Void space gas is released from an adsorbent bed (3) at a 
higher adsorption pressure by cocurrent depressurization of 
the bed. The released gas is passed to another bed (4) of a 
pressure swing adsorption system to equalize the pressure 
therebetween, the other bed being initially at a lower 
pressure. A portion of the product effluent withdrawn from 
yet another bed (1) of the system is not passed to the bed (4) 
undergoing repressurization, as in conventional practice, but 
is passed to an external repressurization storage tank (13) 
during said pressure equalization step. Upon completion of 
this step, the product effluent is withdrawn from the 
repressurization tank and passed to said bed (4) undergoing 
repressurization.  
     This process enhances the recovery of product gas such 
as purified hydrogen in hydrogen-containing feed gas mix­
tures containing carbon dioxide.
Patent EP-0093264-A3 (EP)
IPC: C23G3/00
Filed: 1983-03-26
Abstract: A continuous method for cleaning metallic particles such 
as fines, chips and the like, includes continuously introduc­
ing the dirty metallic particles into a flow path in sufficient 
quantity to form a bed of the particles. The bed is moved 
along the flow path toward a discharge point while con­
tinuously agitating the bed of particles. A gravity flow of a 
detergent solution is provided along the flow path to flow 
through the bed of particles contra to their movement. The 
solution is drained from the path at a point beyond the point 
at which the particles are introduced so as to carry dirt away 
from the bed. The apparatus for performing the method 
includes a rotatable hollow drum (14) having the lowest 
portion of its second end elevated with respect to the lowest 
portion of its first end. The particles are continuously 
introduced to the interior of the drum (14) at a point 
intermediate the ends thereof. A helical worm (42, 44) 
mounted to the drum interior extending from the first to 
second end cooperates with rotation of the drum (14) to 
transport the particles to the second end of the drum (14). 
The detergent solution is introduced into the drum interior to 
flow over and through the particles, and is drained from the 
drum (14) near the first end thereof. Following draining from 
the drum (14), the solution is continuously passed through a 
separating device (88) for separating oil and dirt from the 
solution.

Title: Fiber optic amplifier
IPC: H01S3/06
Filed: 1983-07-27
Abstract: An optical fiber bidirectional amplifier includes a pair of small diameter optical fibers (12a, 12b), arranged in a side- by-side configuration, the first fiber (12a) providing a pumping source and the second fiber (12b) doped with a material which will lase at the frequency of the signal to be amplified. The signal to be amplified propagates through the second fiber (12b) to stimulate emission of coherent light from the lasing material, resulting in amplification of the signal. The refractive index of the first and second fibers (12a, 12b) is substantially identical, but the coupling characteristic provided by the geometrical relationship between the pair of fibers (12a, 12b) yields a wavelength dependent coupling efficiency. Specifically, the coupling efficiency at the wave- lenght of the pumping source is relatively high, while the coupling efficiency at the wavelength of the signal to be amplified is relatively low. Thus, the pumping illumination is coupled from the first fiber (12a) to the second fiber (12b) to stimulate the doping material in the second fiber (12b), while the signal to be amplified remains relatively uncoupled, and is amplified by the coherent light emitted by the lasing material.

Abstract: Es wird eine Einrichtung zur Drehbearbeitung von lang­
gestreckten, zylindrischen oder leicht konischen Werkstücken 
(88), insbesondere Patronenhülsen für Feuerwaffen, besch­
rieben, die in einem Gehäuse (17) wenigstens zwei anget­
riebene Drehspindeln (80) aufweist. Das Gehäuse (17) ist um 
eine Achse (16) schwenkbar aufgelagert und mittels eines 
Hydraulik- oder Pneumatikzylinders (22, 23) angetrieben. Das 
Gehäuse (17) wird durch den Hydraulikzylinder (22, 23) aus 
einer Anfangsstellung schrittweise in weitere Betriebsstel­
lungen und wieder zurück verschwenkt. Als Werkzeuge zur 
Bearbeitung der Patronenhülsen (88) sind ein die Abzieher­
rille (93) und den Abzieherbund (92) formender Drehstahl und 
ein Abstechstahl (103) vorgesehen, die an einem Abs­
techschlitten (101) befestigt sind. Dieser Abstechschlitten 
(101) ist quer zur Achse der Drehspindel (80) auf einem 
Hauptschlitten (94) hin- und herverschiebbar geführt, der 
selbst wiederum in Richtung der Längsachse der Drehspindel 
(80) verfahrbar ist. Dadurch wird die Länge der Patronenhülse 
exakt bestimmt. Weiterhin ist jede Drehspindel (80) einzeln 
angetrieben, wobei mittels einer Kupplung (67) jede Drehs­
pindel für sich an den Antrieb angeschaltet werden kann. 
Dadurch wird immer nur eine Drehspindel angetrieben, 
während die anderen nicht angetrieben bleiben. Damit wird 
die Beladezeit verkürzt und die Beladung vereinfacht.

Abstract: A metal cable corrosion monitor comprises a sensing 
head (14) located about a multi strand cable (1). The sensing 
head includes a field windings (3) for applying a magnetic 
field coaxially to a portion of the cable to be monitored. A 
pick-up coil (2) encircles the portion and detects magnetic flux 
parallel with the cable and linking with the area of the pick-up 
coil.  
     The signals from the pick-up coil are processed by a high 
gain amplifier (8) and phase sensitive detectors (7) and (6), the 
former phase sensitive detector producing an output in phase 
with the field winding driving frequency and the latter phase 
sensitive detector producing a quadruture output relative to 
the field winding driving frequency. By observation of the 
amplitude and the phase output parameters it is possible to 
detect corrosion of a single or multi strand cable. A particular 
format of field winding is disclosed whereby the effects of 
induced inter strand currents can be reduced.

Filed: 1987-03-06
Abstract: In a video recorder, in which the available frequency range has been extended to about 7.5 MHz by means of circuit means, a frequency- modulated sound carrier (T1u, T2u) is recorded in the upper frequency band (B). During the reproduction, the frequency is converted back to the original frequency (5.5 or 5.74 MHz) by means of a mixed carrier (M) obtained from the line.

Abstract: An electric motor-actuated load clamp (12) for automati­
cally-guided vehicles (10) has clamp arms (16) which are 
selectively opened and closed by a plurality of rotary elec­
tric motors (28) connected to the clamp arms by ball screws 
(18, 20, 22). Clamping force is accurately controlled by 
regulation of current to the electric motors (28), any of a 
number of different predetermined clamping forces being 
selectively obtainable. During clamping of a load, the elec­
tric motors (28) are energized only a small fraction of the 
time according to a time-sequenced alamping and reclamp­
ing procedure, clamping force being otherwise maintained 
by a one-way brake (42). Further control features ensure 
against inaccuracy and overclamping due to current inrush, 
and against malfunctions which could cause safety hazards.
