Title: Depressed cladding fiber design for reducing coupling to cladding modes in fiber gratings
Inventor: HAGGANS CHARLES W
IPC: G02B6/036
Filed: 1997-10-30
Abstract: A waveguide, such as an optical fiber waveguide for guiding light waves, which can provide a strongly reflective grating (e.g., a Bragg grating) at a specified wavelength while maintaining very low losses at adjacent wavelengths. The waveguide includes a core, an inner cladding laterally surrounding the core, an outer cladding laterally surrounding the inner cladding, and a grating pattern. The core has a refractive index nco and a first transverse dimension 2A. The inner cladding has a width W and a refractive index nic. The outer cladding has a refractive index noc. The relation between the refractive indexes, nco⊃noc⊃nic and 0,5∫A/(A+W)∫1, define a narrow depressed well region for limiting cladding losses.

Abstract: In a digital signal multiplexing device of a
digital signal multiplexing and demultiplexing system,
two multiplexers (21) respectively multiplex first and
second programs of first to N-th MPEG2 compression
encoded digital video signals into first and second
transport signal sequences in accordance with an MPEG2
transport signal scheme, where N represents an integer
which is two or greater. In accordance with a time
division multiplexing scheme other than the MPEG2
transport stream scheme, a single multiplexer (23)
further multiplexes the first and the second sequences
into a multiplexed digital signal comprising a succession
of payloads in which the first to the N-th digital video
signals are time division multiplexed. The system is
useful in a wholly digital broadcast service for more
than a score of satellite broadcast channels.

Abstract: Procedure for the preparation of a solid carrier for olefin polymerization catalysts,
comprising the steps:
   a) impregnating a silica with a solution of Mg-chloride in the presence of electron
donors,   b) drying the impregnated silica obtained in (a) and impregnating it with a solution
of Mg-alkyls in SiCl 4  at a temperature from -10 to 20  o C, optionally adding a
further amount of electron donors,   c) subsequently treating the slurry obtained in (b) at a temperature from 40  o C to
reflux temperature,   d) drying the carrier obtained in (c).    
     The carrier which is obtained according to the above procedure is advantageously

Abstract: An improved axle control apparatus for industrial
vehicles. A multi-movement hydraulic cylinder (6, 7) is
provided at each end of a rear axle (2) to couple the rear
axle (2) with a body frame (1). Each cylinder (6, 7) has a
pair of oil chambers (23, 24), which are defined by a piston
(25). The oil chambers (23, 24) of the same cylinder (6, 7)
are connected with each other by an oil line (101-104,
111-114). An electromagnetic valve (8, 12) is located in
each oil line (101-104, 111-114). When the electromagnetic
valve (8, 12) opens the lines (101-104, 111-114), oil flow
between the chambers (23, 24) of the same cylinders (6, 7) is
permitted. This permits the pistons (25) to move. When the
electromagnetic valves (8, 12) close the lines (101-104,
111-114), oil flow between the chambers (23, 24) of the same
cylinders (6, 7) is prohibited. This locks the pistons (25)
When the pistons (25) in both cylinders (6, 7) are movable,
the rear axle (2) is permitted to tilt relative to the body
frame (1). The rear axle (2) is locked by locking the piston
(25) of at least one of the cylinders (6, 7). Thus, if one
of the cylinders (6, 7) is malfunctioning, the rear axle (2)
is locked by the other cylinder (6, 7). The reliability of
the apparatus is improved accordingly.

enzymatic hydrolysis of a starch molecule using glucoamylase after the preparation of
a starch derivative containing a hydrophobic group or both a hydrophobic and a
hydrophilic group, particularly octenyl succinic anhydride starch hydrolyzed by
glucoamylase. Such modified starches are useful as emulsifying and/or

Abstract: A method and apparatus for soldering the core end (3) of an electrical wire (4) to a tinplated spoon (2) of a contact terminal of a connector (1) by means of a soldering sleeve (5) that is a shrinkable tube including meltable soldering material. The method comprises the steps of:

Owing to this method, including the pre-soldering operation, and to the apparatus specifically design therefore, the action of the operator is facilitated in that he has no longer the maintain together the core end, the spoon and the soldering sleeve while heating the whole during a relatively long time. The quality of the resulting soldering is thereby also improved.
