Patent CA-2242038-A1 (CA)
Title: Hydraulic structure for a brake system
Inventor: WARD CHRISTOPHER MARK
IPC: B60T13/22
Filed: 1998-08-06
Abstract: A vehicle brake includes a compact module having an inlet port connected to the return-to-sump line of a hydraulic operating system on the vehicle. The module includes a path to a filter mounted on the module for filtering the operating system fluid and a poppet valve for bypassing a clogged filter. Passages in the module direct most of the return line fluid through a poppet valve which develops a source of back pressure substantially lower that system operating pressure in a cavity in the module and returns the fluid to an outlet connected to sump. A portion of the fluid in the cavity is communicated via a charge port in the module to a hydrostatic system to replenish leakage and shuttle flow in the hydrostatic system and to prevent cavitation. The source of back pressure in the module is selectively connected to spring-applied, pressure-released brakes through a four-way solenoid valve housed by the module. To release the brakes, the valve is actuated to direct pressure to one side of each of the brake cylinders. To apply the brakes, the valve is deactuated to pressurize the opposite sides of the cylinders for hydraulically assisted braking.

Filed: 1998-07-27
Abstract: The invention relates to a linear prediction audio signal processing apparatus, such as a vocoder, including a nonlinear filter to attenuate the residual signal used to excite a linear prediction synthesis filter. The nonlinear filter is capable of reducing the noise component in the signal while keeping only the periodic  component  of  the  speech signal.  This  feature enhances speech quality. The invention also extends to a novel method for processing a residual signal used to excite a linear prediction synthesis filter in order to attenuate wide band additive noise in the speech signal as constructed by the synthesis filter.
Patent CA-2245112-A1 (CA)
Title: Information providing system
Inventor: HOSOMI ITARU
IPC: G06F17/30
Filed: 1998-08-17
Abstract: An information providing system is mainly configured by a terminal and an information storage equipment. The terminal is manipulated by a user to issue an information obtainment request, wherein it has a specific output condition, which is defined by a picture output function and/or a sound output function. The information storage equipment extracts a number of digital information elements to suit the information obtainment request, so that the digital information elements are synthesized together into digital information in accordance with a default (information) providing manner, which represents a specific display screen whose screen size and layout are determined in advance. Then, the digital information is transmitted to the terminal, which in turn provides the user with content of the digital information by using pictures and/or sounds. If the default providing manner does not match with the output function of the terminal, the information storage equipment changes the default providing manner by one of change methods, which is selected in consideration of the preset priority. Thus, the digital information elements are synthesized together into the digital information in accordance with the changed providing manner. Incidentally, if the terminal does not have a necessary software module required for outputting the digital information, the terminal downloads it from its resource.

Filed: 1997-05-06
Abstract: A pipe coupling has an elastomer packing collar (5) arranged in a closable housing (4) with radial end walls (14) and comprising two axially spaced apart ring-shaped beads (6) which project radially inwards and sealingly lie against a pipe (1, 2). Each ring-shaped bead (6) subdivided into two adjacent radial beads (8, 9) by a ring-shaped gap (7) oriented at an acute angle to the longitudinal axis of the pipe coupling. This gap (7) forms at the outer radial bead (9) a sharp-cornered packing lip (10). The ring-shaped gap (7) may be closed by pressing together and elastically deforming the two adjacent radial beads (8, 9). Each front side (11) of the packing collar (5) is inclined inwards towards the longitudinal axis of the pipe coupling. A conical clamping ring (13) with a subdivided circumference axially and radially supported on the housing (4), lies against the front side (11) of the packing collar (5). When the housing (4) is narrowed and closed and the packing collar (5) is clamped, the clamping ring (13) lies on the corresponding pipe (1 or 2) of the piping. The inwardly inclined front side (11) may be substantially designed as an inner cone (12) and the clamping ring (13) may have a rounded inner edge (20).
