Title: Suppression of noise and distortion in fiber-optic systems
Inventor: BLAUVELT HENRY A
IPC: H04B10/58
Filed: 1993-05-21
Abstract: SUPPRESSION OF NOISE AND DISTORTION                IN FIBER-OPTIC SYSTEMS            Abstract of the Disclosure Noise  and  distortion  due to  scattering  and reflection in a fiber-optic communications system are suppressed by  modulating  the  optical  frequency  of (chirping) a laser light source to broaden the spectrum of the  laser  light output.   The broader  spectrum spreads the noise produced by an unchirped source over a broader band.   A noise and distortion suppression system includes a chirp signal generator coupled to the signal path of an RF input signal carrying information to modulate the laser optical output.  In some cases, the frequency of the chirp generating signal may result in second-order intermodulation products falling within the information band.   In such cases, the RF input signal  is  predistorted  to  offset  the  expected distortion products.

Patent CA-2100230-A1 (CA)
Title: Simple gas shaft sealing device with flexible rotor
Inventor: BEAR CLAYTON
IPC: F16J15/34
Filed: 1993-07-09
Abstract: This invention relates to a lubricating film type gas seal having a stationary sealing ring (stator) with a radially extending sealing face and a rotating mating seal component (mating rotor) with a radially extending sealing face. The present seal has a reduced number of components and is greatly simplified from working seals described in prior art. The mating rotor is deliberately flexible, and hence it may distort (tilt) throughout an angular range during hydrostatic and hydrodynamic operation and is dependent on rotational speed, pressure, temperature and is also a function of its material and geometric properties. The stationary ring sealing face complies to and follows the angular distortion (tilting) of the mating rotor sealing face in a converging or diverging manner throughout the hydrostatic and hydrodynamic operational range. The flexibility of the stator is a function of its geometric and material properties. Mating rotor and stator flexibility is preferably matched (e.g. using Finite Element Analysis (FEA) techniques) to provide a system flexibility which produces optimum sealing performance. The mating rotor may possess multiple radial sealing surfaces as well as one or more cylindrical sealing surfaces. Initial mating rotor and/or stator seal face angular deflection may be introduced by applying stress and producing subsequent deformation of the structure by a mechanical means.

Title: Air hammer adjustable mounting apparatus for the removal of heavy duty truck rear axle shafts
Inventor: SIEMENS DAVID
IPC: B23P19/02
Filed: 1993-07-21
Abstract: ABSTRACT OF THE DISCLOSURE   Removal of heavy duty truck rear axle half shafts is seldom an easy task since the axle shafts are generally seated within their housings quite stubbornly. It is common to use a sledge hammer to break loose the axle flange from the hub. This practice often results in inadvertent damage to hub studs; and injury to the mechanic is not an uncommon occurrence. The invention presented herein overcomes these difficulties by providing a height adjustable mounting apparatus for a conventional air hammer so that the hammer may be accurately aligned with the axle flange and removal of the axle shaft accomplished rapidly, safely and with no attendant damage to hub studs. The apparatus is comprised of a wheeled horizontal frame to which is welded a first, generally rectangular vertical frame. A second rectangular vertical frame is attached to the first vertical frame via a plurality of rollered brackets and the second frame is free to move in the vertical plane with respect to the first vertical frame. A cylindrical hub shroud with an air hammer centrally mounted at one end is affixed to the second vertical frame and a means for raising and lowering the second vertical frame and thus the shroud, is provided. A pair of rotatable bars, mounted to the wheeled horizontal frame are used to lock the shroud to the truck hub during axle shaft removal.
