Patent EP-0353086-A3 (EP)
Title: Method for lining pipe inner surface in multibranch piping
IPC: F16L58/02
Filed: 1989-07-28
Abstract: The present invention provides a method capable of 
lining a multibranch piping with a coating material 
within the pot life of the coating material without 
leaving uncoated area or excessive repeated coating. 
Lining for a main pipe is performed by pouring the 
coating material into the main pipe (1) from an end portion 
of the pipe, and lining for branch pipes (10) is effected by 
the feed of the coating material and air for each of the 
branch pipes. A completed time point of lining in each 
branch pipe is detected by any of the following methods: 
   A) A method wherein the time required for lining a 
branch pipe is estimated in advance and upon lapse of 
the estimated time it is judged that the lining for the 
branch pipe was completed.    (B) A method wherein a change in gas pressure in the 
main pipe which occurs upon arrival of the coating 
material at the connection between a branch pipe and the 
main pipe under the feed of air is detected by a 
pressure gauge, whereupon it is judged that the lining 
for the branch pipe was completed.    (C) A method wherein when the coating material fed from 
an end portion of one branch pipe was discharged from 
 
 
another branch pipe located in a position close to the 
one branch pipe, it is judged that the lining was 
completed.

(8) for servo-locking the pickup (3) to a position 
where the reading of the data contained in the 
program area is interrupted and controlling the servo 
mechanism (4) so that the pickup (3) is positioned in 
a predetermined position allocated with a 
predetermined address for subsequent resumption of 
the data reading if an address of the servo-locked 
position is outide the program area.

Title: System for injection molding elongated bodies
IPC: B29C45/00
Filed: 1989-05-17
Abstract: A tire tread (74,76,194) is injection molded 
by increments in a mold cavity (56,58,119,224,262) 
having an open end (110,272) closed by a trailing end 
(116) of a cured section (114,228). A temperature 
moderating closed end (109,207,268) prevents complete 
curing of a trailing portion (116) of the cured sec­
tion (114,228) while the rest of the section is 
cured. The mold (14,16,90,188,236) is opened so that 
the cured section (114,228) may be shifted to a posi­
tion where the trailing portion (116) is clamped in 
the open end (110,272) of the mold cavity 
(56,58,119,224,262). A second section (118,228,264) 
is injection molded in the cavity (56,58,119,224,262) 
and the partially cured trailing portion (126) of the 
cured section (114,228,264) is cured and adhered to 
the leading portion (130) of the second section 
(114,228,264) as the second section is cured. This 
process may then be repeated for later sections to 
provide a desired length of cured tire tread stock 
(74,194,264). The mold (14,16,90,118,188,236) may 
have substantially flat molding surfaces (108) or 
longitudinally and curved molding surfaces (192,210,­
244). Mold segments (204,206,208,256,258,260) for a 
circumferentially curved mold cavity (224,262) may 
also be provided.
Patent EP-0375632-A3 (EP)
IPC: H01L21/762
Filed: 1989-12-06
Abstract: Encased (BOX) trench isolation structures in a silicon 
substrate are formed by firstly RIE etching an ONO multilayer 
(Oxide-Nitride-Oxide) formed on the surface of a monocrystal­
line silicon substrate through a mask defining the active 
areas until exposing the silicon. A successive deposition of 
a conformable TEOS oxide layer followed by a "blanket" RIE 
etching, leave tapered "spacers" on the vertical etched 
flanks of the ONO multilayer. Through such a self-aligned 
"aperture" an isotropic plasma etching (round-etch) of the 
silicon is performed until the lateral, under-cut, etch front 
below the oxide spacers reaches the bottom layer of the 
isolation area defining etching previously conducted through 
the ONO multilayer. The peculiarities of the round-etch 
profile are thus fully exploited for more easily implanting 
the walls and bottom of the trench and avoiding the presence 
of electric field affecting sharp corners. The process 
maintains a precise lateral dimensiohal control and does not 
require special high resolution apparatuses.

Title: Aircraft ground-handling vehicle
IPC: B64F1/22
Filed: 1988-01-22
Abstract: A towing vehicle for moving aircraft without a towing bar has a driving frame (5) with a forked receiving space formed between the wheels of an axle, in which is arranged a retractable and extendable gripping and pulling device (28, 68) that cooperates with a lifting device and that engages the nose wheel (24) of the aircraft, pulling it on a paddle (14) up and down with respect to the driving frame. A single paddle (14) is provided to support the nose wheel (24) in the proximity of the line of influence of the nose wheel load, thus preventing blocking and deforming forces from acting upon the nose wheel (24) while this is pulled or lifted. The paddle can pivot around a horizontal axis arranged on the driving frame, and its pivoting position can be controllably adjusted relative to the driving frame. In a further development, the paddle can additionally tilt at an angle to the horizontal axis, thus preventing unacceptable strains when the towing vehicle carrying the nose wheel follows a curved path. Preferably, the paddle is steered on the driving frame by means of a parallelogram or trapezoid linkage (70, 71, 73, 74).
