Patent GB-2329097-A (GB)
Title: Echo cancellers
Inventor: LI TOM HONG
IPC: H03H21/00
Filed: 1998-09-03
Abstract: An echo canceller 200 transforms at 202 the far-end speech into its linear prediction residual. The updating direction for the coefficients of an adaptive filter 110 are formed in two steps in a coefficient generating circuit 204. In the first step, the updating direction is formed in the linear prediction residual domain. In the second step, the updating direction used in the coefficients adaptation are obtained by transforming the updating direction from the residual domain to the speech domain. The echo canceller 200 including a linear prediction circuit 202 may be constituted by a microprocessor or a digital signal processor. The echo canceller provides a high level of echo suppression while being stable and uses a computationally efficient adaptive filter which converges quickly. The echo canceller may be used in teleconferencing or in a radio telephone.

Title: Shaft-hub unit
Inventor: BEIGANG WOLFGANG
IPC: B60K17/22
Filed: 1998-05-08
Abstract: The invention relates to a shaft-hub unit with a toothing system for transmitting torques, comprising a shaft (1) with shaft toothing (5) and a hub (2) with hub toothing (7). Said shaft toothing and said hub toothing mesh with each other. According to the invention, torques are introduced via a shaft stem (4), the shaft toothing (5) being situated at the end of said stem. The tooth profile of said shaft toothing (5) is variable in a longitudinal direction. The tip diameter of the shaft toothing (5) is constant in a longitudinal direction and the root diameter of the hub toothing (7) is constant in a longitudinal direction. The toothing system has at least two areas (9, 10) which extend axially. In each area, the root diameter of the shaft toothing (5) is constant and the tip diameter of the hub toothing (7) is constant. For each pair of adjacent areas, the area which faces towards the shaft stem (4) has the greater shaft toothing (5) root diameter and the greater hub toothing (7) tip diameter. Equally, for each pair of adjacent areas, the area facing towards the shaft stem (4) has a shaft toothing (5) tooth profile which is congruent with a tip section that forms the upper part of the adjacent area.

Title: Improved hitch for a tractor
Inventor: CRABB ELMER R
IPC: A01B59/06
Filed: 1998-07-24
Abstract: A hitch assembly (10) for a tractor (14) is disclosed, which includes a rotatable carriage support (58) that is carried on a fixed trunnion (32) for providing oscillation of the hitch frame (124)about horizontal first axis (42). The rotatably carriage support (58) also pivotally mounts a hitch carriage (22) about a second axis (64) to provide the hitch assembly (10) with the ability to articulate as well. Camming apparatus (106) is also provided to progressively restrict the oscillation of the hitch frame (124) as it is being raised and stop surfaces (114, 116) restrict articulation when the hitch frame (124) is in its raised position. The articulation and oscillation ability of the hitch provides improved ease of steering and control of the tractor (14) and improved ground contact of a ground-contacting implement on the hitch frame (124). A power-take-off shaft (40) extends through said center (28) of the fixed trunnion (32) supporting the hitch mounting (20) to permit simultaneous connection of the implement with the hitc and the power-take-off shaft (40) for transmitting rotary power to the implement.

Title: Antenna arrangement and method of manufacturing an antenna arangement
Inventor: LEWIS ROBERT ALAN
IPC: H01Q19/13
Filed: 1999-02-26
Abstract: An antenna arrangement particularly for millimetric data communication includes a reflector 13 and feed horn 11. The feed horn is embedded in a dielectric block 14 which is transparent to radiation at which the arrangement operates(e.g. perspex or polystyrene). The reflector 13 is a layer of metallisation laid down on an outer surface of the dielectric block 14 and is thus fixed in position relative to the feed horn 11. A protective layer 15 may be laid down on the outer surface of the reflector 13. The antenna arrangement may be formed by moulding techniques or other techniques particularly suited to high volume production. In one method, the block 14 is formed firstly as two separate pieces which are moulded to each include half of the feed horn 11 and the waveguide 10 to which it is connected. The feed horn and waveguide are metallised and the pieces are joined with the channels in register to form the complete component. In an alternative method the feed horn 11 and waveguide 10 are of constructed by only forming a channel on one of the surface of one of the pieces.

Title: Hydraulic lift cylinder assemblies
Inventor: DAVIES ANTHONY ROGER
IPC: F15B15/14
Filed: 1999-04-26
Abstract: An hydraulic bath seat lift has a hydraulic cylinder assembly 1 comprising an inner cylinder 20 fixed with the floor and an outer cylinder 30, which can be raised and lowered by supplying hydraulic fluid to the assembly. The outer cylinder 30 supports a seat 13 at the end of a horizontal arm 12. The inner cylinder 20 has a pin 25 at its upper end projecting outwardly into one of two sets of longitudinal grooves 31 and 33, or 32 and 34 along the inner surface of the outer cylinder 30 to prevent the outer cylinder rotating relative to the inner cylinder. The grooves open into one another at the lower end of the outer cylinder 30 so that when the outer cylinder is raised fully, to lift the seat 13 above the bath 2, the cylinder can be rotated to swing the seat over the bath and then lowered with the pin 25 engaging the other set of grooves.

Title: Packaging closure with integral utensil
Inventor: DUFFETT JONATHAN MARK
IPC: B65D51/24
Filed: 1999-08-19
Abstract: A packaging closure is formed with an integral utensil, such as a spoon, for extracting the contents of the container, the utensil being separable from the remainder of the closure 1 along a line of weakness 5, which may be scored or perforated. In use, for the embodiment shown, pulling tab 2 urges two peripheral regions 9 to rotate about lines of weakness 11 and separate from the remainder of the closure 1 along lines of weakness 5 and 7. Once the angle of rotation of parts 9 is sufficient, they are folded in towards each other about a line of longitudinal weakness 15. This causes the adjacent regions 19 to also fold inwards along the axis 15, causing the regions 19 to detach from the closure 1 along the line of weakness 5. This folding allows the utensil to be longer than the diameter of the closure and adds to the rigidity. The utensil is finally rotated about the join between the triangular region 21 and the remainder of the closure 1 so as to fully separate the two. In an alternative embodiment the utensil pre-formed and is ready to use once separated from the remainder of the closure.

Title: Remote supervisory equipment
Inventor: TAMADA KAZUYOSHI
IPC: H04L69/40
Filed: 1991-01-30
Abstract: PURPOSE:To suppress malfunction due to noise and to detect a required momentary status change by providing a means discriminating the presence of a state change when the content of a monitor input signal represents the presence of a status change consecutively or repetitively for a preset prescribed time. CONSTITUTION:A data resulting from sampling a supervisory input signal by a sampling circuit 2 for a prescribed rate is inputted to a counter 3, and an alarm is set when the data is logical H and number of times of H level is counted. When the count of H levels reaches a prescribed SQ value, the counter 3 gives an output to an output circuit 4 and the circuit 4 gives the presence of a status change to a supervisory control section 5. The control section 5 sends the collected supervisory state to a central station periodically or on request. Moreover, the counter 3 is reset periodically by a control circuit 6 and when the count does not reach the SQ value within a reset period, no output is generated. Thus, malfunction due to noise or aperiodic momentary change is prevented and a required momentary status change is detected.
