Title: Escalator or moving walk with drive
Inventor: ILLEDITS THOMAS
IPC: B66B21/02
Filed: 2007-09-18
Granted: 2014-09-09
Abstract: In this escalator or in this moving walk, the drive (2) is arranged in the reversing area (1). The drive (2) drives chain wheels (5, 5.1) that move the step band or pallet band (5, 5.1) and consists essentially of a motor (6), an axial gear (7), and a first hollow shaft (8) and a second hollow shaft (14). By means of a first pulley (9) the motor (6) drives a belt (10) that in its turn drives a second pulley (12) that is arranged on a gear input shaft (11). Arranged at one end of the rapidly rotating gear input shaft (11) is an operating brake 13; the other end of the gear input shaft (11) is connected to the axial gear (7). The gear input shaft (11) runs coaxial to the first hollow shaft (8). A first flange (15) bears the first chain wheel (5) on the truss. Arranged at one end of the second hollow shaft (14) is the second chain wheel (5.1). The other end of the second hollow shaft (14) is connected to the housing (7.1) of the axial gear (7). A second flange (16) that is connected to the side plate (4) or supporting plate (34) serves as torque converter bearing for the axial gear (7).

Abstract: A nursing bottle having a vent tube (113) that extends to vent pressure at all times. The vent tube extends distally from the vent insert (117), operatively associated with a collar, that holds the vent structures and the nipple to the wide rimmed opening. In addition, the vent tube has a conical shape of decreasing diameter distally toward the center of the bottom to dissipate the pressure that may cause leakage from the bottle. Further, the vent insert has a major (124) and minor seal (125) that prevents leaks out of the collar and onto an infant.

Title: A method for reshaping, regeneration and retiming of optical data signals and semiconductor for use therein

Granted: 2010-08-17
Abstract: A method and system for AO3R functionality is presented. The system includes an AO2R device followed by an AOCR clock recovery module and an AOR  retiming device. The AOR retiming device takes as input a recovered clock signal extracted from the output of the AO2R by the AOCR clock recovery module. The output is the recovered clock signal gated by the regenerated and reshaped input signal, and a monitor circuit is used to set the optimum operations of the retiming device. In a first embodiment the output of the AOR retiming device is fed to an AOC code and wavelength conversion output stage, which returns the signal to the NRZ coding, on a service wavelength converted to match the fixed wavelength connection with the DWDM transmission system. In a second embodiment the code conversion is incorporated into the AOR retiming device, and wavelength conversion is accomplished in the AOCR clock recovery device.     Previous schemes for performing the 03R functionality use some level of Optical-to-electronic (OEO) conversion to generate the clock signal. The AO3R  scheme presented here carries out all three functions in the optical domain, and returns a clean output signal using identical coding as the input, on a wavelength of choice.

Abstract: The risk of oil spills in the sea ice-covered polar regions is on the rise as more and more crude oil is prospected and transported. No bioremediation methods have been used until now because they seemed to work only above the melting point, whereas the temperatures prevailing in the ice-covered regions lie below the melting point. Currently spills are preferably removed in a mechanical or physical-chemical manner, leaving residual pollution and damaging the environment. In the bioremediation method according to the invention, the petroleum hydrocarbons that are to be decomposed are brought in contact with an inoculum comprising, in addition to an environmentally friendly carrier material and nutrients, a mixture of different cold temperature-adapted, indigenous bacterial strains which are adapted to different decomposition places and petroleum hydrocarbons that are to be decomposed as a result of the fact that said bacterial strains have a different decomposition spectrum and oil emulsification behavior as well as a different salt and temperature tolerance range while continuing to be active at -3°C. Suitable bacterial strains and enzymes obtained therefrom can be produced by concentrating and isolating bacteria in a laboratory in real ice conditions at -3°C and with oil contamination. Eleven preferred bacterial strains have been filed with the German Collection of Microorganisms and Cell Cultures Ltd. (DSMZ).
