Title: Window jamb liner with concealed spring pocket and friction slide
Inventor: STARK IVAN L
IPC: E05D15/22
Filed: 1991-02-07
Granted: 1996-01-02
Abstract: A jamb liner, or facing member, for movably mounting windows along their side edges in channels or runs, in which a concealed elongated chamber is provided for a coil spring or the like used as part of the balance or positioner mechanism by which the window is supported in different positions along the length of the jamb as it is opened and closed during use.  Preferably, such concealed chamber includes an elongated wall which projects outwardly from the jamb liner and has an arcuate or other angularly-configured cross-section, such that it presents a generally closed appearance when viewed from a position near the window.  Such chamber-concealing wall defines an elongated opening through which the balance device may communicate for access by the window  ash, for supporting the latter and positioning it.  In addition, a novel balance apparatus is disclosed which comprises a friction shoe configured to slidably move within the aforementioned chamber and frictionally engage a rib extending therewithin, as a function of and in response to the applied weight of the sash.

Title: Air/fuel ratio control system and method for fuel vapor purging
Inventor: DAVENPORT MARTIN FREDERICK
IPC: F02D41/00
Filed: 1991-10-04
Granted: 1999-05-04
Abstract: A system and method for controlling operation of an engine wherein a fuel vapor recovery system is coupled between an air/fuel intake and a fuel supply system.  An air/fuel ratio indication is provided by a proportional plus integral feedback controller coupled to a two-state exhaust gas oxygen sensor. In response to the air/fuel ratio indication and a measurement of inducted air flow, a base fuel command is generated.  To compensate for purging of fuel vapors, a reference air/fuel ratio is subtracted from the air/fuel ratio indication and the resulting error signal generated.  This compensation factor represents a learned value which is directly related to fuel vapor concentration, and it is subtracted from the base fuel command to correct for induction of fuel vapors.  At initiation of fuel vapor purging, the rate of purge flow is incremented a predetermined amount with each change in state of the exhaust gas oxygen sensor.

Title: Adaptive equalizer for digital cellular radio
Inventor: TOPLIS BLAKE STEPHEN
IPC: H04B7/005
Filed: 1992-02-26
Granted: 1998-05-26
Abstract: The present invention provides a method of estimating parameters of a mobile radio channel which are used for providing the equalization and synchronization of the radio channel.  The channel is modelled as a discrete number of independent Rayleigh-faded propagation paths. First, the relative delay of each path is estimated, using maximum likelihood methods.  Using this information, the associated time-varying path weights are then determined using a least-squares fit.  This is sufficient information to estimate the impulse response of the channel.  The actual equalizer weights are then obtained by inverting the estimated channel impulse response.

Abstract: SURFACE CONTOURED PRESS JACKET FOR A SHOE PRESS            ABSTRACT OF THE DISCLOSURE          A press jacket is formed of an elastomeric jacket material having two layers of reinforcement threads, namely an inner layer and an outer layer, embedded in it.  The inner layer is formed of longitudinal threads which upon operation of the press device extend parallel to the axis of rotation of the press jacket.  The outer layer is formed by a fabric layer or by circumferential threads which are wound helically and which, upon operation of the press device, extend approximately in the direction of travel of the press jacket.  The reinforcement threads are surrounded by the layer of elastomeric material, which is produced homogeneously.  The inner surface of the press jacket has longitudinal grooves which extend parallel to the longitudinal threads and have a depth of 0.1 to 0.2 mm. Various techniques of forming those grooves are described, including enlarging the longitudinal threads, pressing on the jacket which thereby deforms around the threads, forming voids or channels in the jacket rather than having threads therein or having the press jacket material deform around the threads due to application of heat or pressure to the press jacket.

Title: Method of detecting a routing loop in a telecommunication network, telecommunication network for using the method, and detection means for use in the telecommunication network
Inventor: BROCKEN FRANCISCUS WILHELMUS A
IPC: H04Q3/545
Filed: 1993-02-12
Granted: 1996-12-10
Abstract: Known methods of detecting routing loops in telecommunication networks are cumbersome and time-consuming. In addition, the probability that an existing routing loop is even actually detected is too low. In a method of detecting a routing loop according to the invention, paths whose lengths are stored are assembled. As soon as the length of a (partly assembled) path exceeds a predetermined value which is greater than, or equal to, the largest existing path length in the telecommunication network, this indicates the existence of a routing loop.
