Patent EP-0291200-A3 (EP)
IPC: G02B6/28
Filed: 1988-04-28
Abstract: A birefringent single-mode optical fiber (200) which 
propagates light into orthogonal polarization modes is 
subjected to a series of second order traveling flexural 
waves for propagation within the fiber (200). An acoustic 
wave generator (202) applies a periodic lateral squeezing 
force to the fiber (200), thus causing a second order 
flexural wave to propagate within the fiber (200). The 
wavelength of the second order flexural wave is selected to 
cause light propagating in one polarization mode to be 
coupled to the orthogonal polarization mode. The optical 
signal in the second orthogonal propagation mode has a 
frequency which is equal to either the sum of or the 
difference between the frequency of the optical signal in 
the first propagation mode and the frequency of the 
traveling flexural wave. The frequency of the optical 
signal in the second orthogonal propagation mode is shifted 
upward of or downward from the frequency of the optical 
signal in the first propagation mode as determined by the 
direction of propagation of the first optical signal with 
respect to the direction of propagation of the traveling 
flexural wave, and as also determined by whether the phase 
propagation velocity of the optical signal in the first 
propagation mode is greater or less than the propagation 
velocity of the optical signal in the second propagation 
mode. The centripetal couple of squeezing forces is 
preferably oriented at an angle of substantially 45° with 
respect to the axes of birefringence of the fiber (200).

Patent EP-0296967-A3 (EP)
IPC: H03K4/02
Filed: 1988-06-22
Abstract: An autozeroing operational amplifier for a 
voltage or current-to-frequency converter includes a 
master amplifier and a slave amplifier. The master 
amplifier uses the voltage across a master capacitor to 
control the polarization level of an MOS transistor. 
Changing this level changes the operation of a differen­
tial pair connected to a load thereby changing the am­
plifier's input offset voltage. The slave amplifier, 
similarly constructed, is connected to periodically 
refresh the voltage across the master capacitor to com­
pensate for drift and temperature effects.

Patent EP-0333209-A3 (EP)
Title: Nonwoven fibrous elastomeric web material and method of formation thereof
IPC: D04H1/46
Filed: 1989-03-17
Abstract: Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed. The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can by hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers. The hydraulic entangling technique provides a nonwoven fibrous elastic material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance. A smooth surfaced and/or highly absorbent elastic web material, with isotropic strength and recovery in both machine- and cross-directions, can be provided according to the present invention.
Patent EP-0342376-A3 (EP)
Title: Electronic position sensor assembly and control system
IPC: F02D41/34
Filed: 1989-04-20
Abstract: An electronic position sensor assembly and 
engine control system (10) in which two sensing 
elements (13, 14) in a dual sensor (12) provide 
separate, independent position signals (A, B) 
related to multi-cylinder engine cycle position by 
sensing the angular position of a engine-rotated 
slotted wheel (11). The sensing elements provide 
identical sensing signals shifted from each other 
by a predetermined angular amount (d). In response 
to the simultaneous providing of a pulse by both 
sensing elements, a first reference signal (at 22) 
identifying a reference cylinder is provided for 
controlling electronic distribution of spark timing 
and/or fuel injection signals to engine cylinders 
(17-20). In response to a selected one of the 
sensing elements producing a pulse which has a 
predetermined longer duration than a preceding 
produced pulse, a second reference signal (after 
50) is produced indicative of top-dead center 
engine cylinder cycle position for one of the 
cylinders. In response to detecting a fault in the 
position signal produced by the one selected 
sensing element, a switch (27) selects the other of 
the sensing elements for utilization in producing 
the second reference signal, and a substitute 
 
 
reference signal circuit (40) provides a substitute 
first reference signal. A less expensive and more 
reliable engine position sensor assembly and engine 
control system is provided since proper system 
operation is maintained despite a fault in one of 
the position signals.

segment for identifying specific indicia of interest and 
loading corresponding indicia information into 
microcontroller memory. Information so stored may be 
selectively downloaded to a central computer (14) for 
processing and generation of records for the patient files.

Title: Centrifugal pump for pumping molten masses, especially molten explosives
IPC: F04D7/04
Filed: 1989-09-30
Abstract: Centrifugal pump for pumping molten masses, especially molten explosives. Molten explosives having a high content of infusible solid explosive are gravimetrically pumped due to the associated dangers. This makes high buildings and protective surrounding walls necessary, with the disadvantage of considerable effort and high costs as well as relatively poor accessibility to the installations. The object of the invention is to avoid these disadvantages and to permit the pumping of molten explosives to be carried out on just a few levels, if not just a single level, in easily accessible and uncomplicated installations. The vertically arranged pump shaft of a centrifugal pump bears at its lower end an unchokeable impeller with upwardly open blades, with which the pump housing forms an annular gap and, at the end, a free space which is connected by means of bores directed obliquely outwards from bottom to top to the pumping space located above the impeller and fed with pumping medium from above. Pumping of molten masses, in particular having a high solids content, and in particular molten explosives having a high content of infusible high-energy solid explosive.

catalyst and a solvent medium capable of dissolving the 
phenoxy resins and otherwise not interfering with the 
polymerization reaction. The solvent medium is 
advantageously free of toxic Methyl Cellosolve.

Abstract: A power operated contact apparatus extends and 
retracts one or more electrical leads into and out of a 
cryostat for making and breaking, at a cryogenic 
temperature, electrical contacts with a superconductive 
circuit. A pair of rigid elongated leads extend into a 
cold space of the cryostat which is at or near a cryogenic 
temperature. A connector is fixed at the inner end of each 
lead for making electrical contact in the cold space with a 
mating connector of the superconductive circuit. A guide 
journals each lead for axial movement and seals against the 
lead using an elastomeric O-ring coated with a lubricious 
polymer. A foundation is attached and sealed to the 
cryostat and to the guide means so that the connector on 
the inner end of the lead is extendable into making 
electrical contact with the connector of the 
superconductive circuit in the cold space. An air cylinder 
operated four bar linkage extends and retracts the leads to 
and from making electrical contact with the superconductive 
circuit in the cold space. The leads are cooled by flowing 
cryogen from the cryostat through them, which flow is 
turned off when they are disconnected, and prevented from 
freezing up outside of the cryostat by a flow of air 
directed around the leads.
