Title: Optical fibre amplifier noise figure measurement
Inventor: UCHIYAMA HARUYOSHI
IPC: G01M11/00
Filed: 1996-08-10
Abstract: The method employs a distributed feedback laser diode (1) producing a continuous beam (A) in the 1.55- mu m waveband for chopping (2) into a pulsed signal (C) with 1- mu s period and 50% duty ratio. The Er<+3>-doped fibre amplifier (4) outputs an amplified signal (D) with delay.  The output is modulated with a pulse (G) from a control unit (3) and converted (6) by a photoelectric detector (6) into a power signal (PO) which is fed back to the control unit. The chopping and modulating pulses (B,G) are adjusted in phase to maintain a maximum photoelectric power level for measurement.

Title: Sawtooth clothing
Inventor: GRAF RALPH A
IPC: D01G15/88
Filed: 1997-09-15
Abstract: The sawtooth clothing, wholly of steel, has a foot (30) which fits into a groove at the carrier. It has a section (40) for a counter unit, complementary to the base support of the groove, to resist sliding movements through forces across the groove base. The foot (30), to form the counter unit, has two sections in succession on the sawtooth blade from the base, where the section nearest to the base (32) has the greater width (B). Where there are three sections, the center section (40) has the greatest or the smallest width. The section of the foot, directly at the base, has a constant width. The sections with different widths are formed by a longitudinal groove in a foot flank (36) to give successive projections, with rounded transits between them. The sawtooth clothing wire blade is pushed into the carrier groove with an insertion roller and a distorting roller, to fit into the side groove structure at the foot zone.  The pressure applied by the insertion roller is less than exerted by the distorting roller.

Patent DE-19746802-A1 (DE)
Title: Pressure injection molding of plastic objects with supplementary gas cushion injection
Inventor: GOSDIN MICHAEL DR
IPC: B29C45/17
Filed: 1997-10-23
Abstract: The compressed gas (or possibly a liquid) is cooled before its injection between mold cavity wall (7) and plastic melt. An Independent claim is included for corresponding injection molding equipment. Preferred features: The gas is fed along a cooled region in the mold, hence cooling the gas. In a particular implementation, compressed gas is initially injected through one transfer port (6'), exemplified by a nozzle or slot, to form a gas cushion (8) between mold cavity wall (7) and plastic. Next, maintaining desired gas pressure in the cushion, compressed gas is removed using a second port (6''), from the region between wall and plastic. At the same time, through the first port, a compressed gas flow follows on. After sufficient cooling of the molding, the pressure is released from the cavity, preferably by gas release via the second port. In this process, before gas introduction, it is cooled. Melt injection into the cavity is so effected, that before gas injection, the cavity is completely filled with melt, at such a pressure that the plastic is precompressed during the first phase of setting. Gas introduction is controlled as a function of pressure in the cavity and/or in accordance with time elapsed since commencing injection and/or with regard to the displacement of the injection screw. Pressure of the gas injected, is controlled in accordance with a given pressure profile, over time. Use of nitrogen gas and temperatures of -100 deg C and -20 deg C is cited. Rapid cooling can be carried out without damaging the molding.
