Patent CA-2290299-A1 (CA)
Inventor: HOECKER FRANK
IPC: B01D46/10
Filed: 1999-11-24
Abstract: An apparatus for depositing solids from a current of air (D), with a bucket wheel lock (3), taking up this air current (D) over a connecting opening (2).  This apparatus has a built-in drum (4) with a rotatably supported bucket wheel (5).  On the one hand, a screen (8) is provided in the drum (4), on which coarse solid particles are deposited from the air current (D) and, on the other, a discharge opening (9) for the separated coarse solids (M) is provided. An air current (E), still containing fine dust particles, is supplied to a dust filter (10) which, in the direction of flow, is behind the screen (8). In the direction of flow of the dust-containing air current (D), behind an essentially horizontal upper region (12) of the screen (8), facing the dust filter (10), the bucket wheel lock (3) is provided with an air current deflection (F'), which brings about a surface removal of dust at the back side (12) of the screen (8).

Title: Fan and compressor noise attenuation
Inventor: TSE MAN-CHUN
IPC: G10K11/175
Filed: 1999-12-22
Abstract: The present invention is a noise attenuation system and related method for suppressing noise having a primary tone generated by a jet engine. An exciting sound wave generator is positioned within the nacelle of the jet engine at its inlet to generate an exciting sound wave having a primary frequency generally different from a frequency of the primary tone of the noise. The exciting sound wave is used to modulate the primary tone of the noise and, therefore, distribute sound energy of the noise from the primary tone to a broad range of side bands so that the amplitude of the primary tone of the noise is reduced. The exciting sound wave generator according to the preferred embodiments is a fence member exposed to the air flow entering the inlet of the nacelle, or an aperture defined in the inner wall of the nacelle to jet a air flow into the nacelle. The noise attenuation system avoids complicated noise attenuation devices used in an active noise control system for sensing the noise frequency and phase, and controlling the frequency and phase of the generated sound wave for a match.

Patent CA-2306255-A1 (CA)
Inventor: GRESZCZUK JOHN A
IPC: H04M11/06
Filed: 1998-10-09
Abstract: A modem for use in Digital Subscriber Line communications transmits and receives data over the local subscriber loop in common with voice information over the loop, while avoiding the need for voice/data splitters. The modem responds to disruptions associated with "disturbance events" such as on-hook to off-hook transitions and the like by rapidly switching between pre-stored channel parameter control sets defining communications over the loop under varying conditions. In addition to changing parameter control sets responsive to a disturbance event, the modem may also change transmission power levels and other system parameters such as frequency domain equalizer characteristics. Further, provisions are made for reduced bandwidth communications under selected conditions.

Patent CA-2323313-A1 (CA)
Inventor: NORDSTROM CARL B
IPC: H01R4/56
Filed: 2000-10-12
Abstract: An electrical conductor splicing assembly includes a tubular shell, and a pair of tubular gripping members and a spring disposed within an interior chamber of the shell. The shell and gripping members are electrically conductive. Each gripping member defines a longitudinal passageway and a cavity within an inner portion in communication with the passageway. The shell and gripping members receive an end of an electrical conductor through each opposite end portion of the shell and within each gripping member. The spring is disposed between the gripping members and has a main portion, a pair of opposite end portions and a pair of reduced diameter portions interconnecting the main portion to the opposite end portions. The opposite end portions of the spring are captured within the cavities of the gripping members. The reduced diameter portions of the spring are disposed adjacent to and extend away from the cavities of the gripping members. The main portion of the spring urges the gripping members away from one another outwardly toward the opposite end portions of the shell which have oppositely tapered configurations. The spring causes the gripping members to abut against the opposite end portions of the shell and press radially inwardly toward and grip the conductors inserted through the gripping members and thereby provide a splice-type electrical connection between the conductors via the gripping members and shell. The reduced diameter portions of the spring block the ends of the conductors from passing farther into the shell through the main portion of the spring located between the gripping members.

Abstract: An end cap seal assembly (10) for an electrochemical cell such as an alkaline cell (8) comprises a convoluted end cap disk (40) which may also function as a cell terminal and an underlying insulating disk (20) also having a convoluted surface. The convoluted end cap disk (40) has a downwardly extending wall (45) with at least one aperture (48) therethrough which preferably faces the ambient environment. The insulating disk (20) has a downwardly extending wall (26) forming a rupturable membrane (23) which underlies and abuts the inside surface of the downwardly extending wall of the end cap. The rupturable membrane underlies and abuts the aperture (48) in the downwardly extending wall (45) of the end cap. When gas pressure within the cell exceeds a predetermined level the rupturable membrane (23) pushes through said aperture (48) and ruptures allowing gas to escape therefrom directly to the environment. A separate terminal plate (120) may be welded to a portion of the top surface of the convoluted end cap (40). The conductive layer of a film-laminate condition tester (155) may be connected to the terminal plate (120).
