Title: Disposable liner
Inventor: BARRIE JAMES
IPC: B44D3/12
Filed: 1996-12-04
Abstract: A disposable liner 16 is provided to line the inside of a roller bin (10, Figure 1), bucket, tray or similar vessel. The liner is preferably a polythene bag adapted to conform to the cavity of the vessel and including a means 20, for example a drawstring or elasticated cord, of tightening the bag on the vessel. Alternatively the liner may comprise punched or moulded plastics or cardboard shaped appropriately to fit. The liner may lie within the vessel and be stretched over the lip, or else entirely envelop the vessel (Figure 3). The liner may be fitted over a paint roller bin and filled with paint, the weight of which ensures that the liner conforms to the vessel. When a job is complete, the liner is removed from the bin, removing the need for cleaning.

Title: Two-stroke i.c. engine exhaust system with active control of effective tuned le
Inventor: ROBERTS JOHN STEPHEN
IPC: F01N1/16
Filed: 1997-01-22
Abstract: Located within the rear section 2 of the expansion chamber is conical baffle 3 attached to an axial stinger 4 which is slidable in a guide 5. The baffle 3 is pre-loaded towards the engine by a spring 13 inside a bellows 19. The shape and position of the baffle 3 is designed to reflect sonic pulses generated by the exhaust port so as to maximise engine efficiency. The invention allows the baffle 3 to be moved along the length of the expansion chamber in response to dynamic engine parameters, eg engine speed. The optimum baffle position is determined by design or experiment and the relationship between baffle position and the control parameter is encoded in the position control system 17. A servo positioned 18 then moves the stinger 4 eg via cables (14, fig.3). Instead of being hollow, the stinger may be solid with a side exhaust gas exit being provided (fig.2).

Title: Heat dissipator using acoustically generated airflow
Inventor: LICHTERFELD STEFAN
IPC: H01Q1/24
Filed: 1997-02-19
Abstract: A cooling arrangement where an acoustically generated airflow is used to dissipate heat. The arrangement is particularly applicable to portable communication units 10 where heat is generated by for example an audio amplifier, power amplifier, signal processor or battery 16. The arrangement preferably comprises a vibrating member, such as a loudspeaker 14, that produces the cooling airflow. In one embodiment, a duct 18 is positioned adjacent to the vibrating member 14 to direct the airflow to the heat generator 16. The duct has an open end with a circular diaphragm 20 such that circular ring turbulences are produced by accelerating air pulses (Figure 3). To reduce noise, the duct may be designed for a particular air volume such that the resonant frequency is below the sensitive audio range. In another embodiment (Figure 2) the duct is provided within an antenna to facilitates airflow from within the communication unit 10. Temperature monitoring (Figure 5) may also be used to initiate the acoustic cooling operation once a threshold temperature is exceeded.

Title: Etch resist comprising waterslide paper with toner image formed by laser photocopier
Inventor: KELLY MICHAEL JOHN
IPC: G03G13/28
Filed: 1998-06-06
Abstract: A resist for etching is obtained by printing a waterslide transfer paper with a toner image using a laser photocopier. The transfer paper is pressed on to the heated surface of the material to be etched (eg metal, glass or cloth) so as to transfer the toner to the surface of the material. The transfer paper is then soaked in water to release the paper from the toner and the material heated to cure the toner which now form a resist for the etch process. After curing the image may be left as decoration.

Title: Suppressing noise in a speech communications unit
Inventor: CHAN DOMINIC SAI FAN
IPC: G10L21/0208
Filed: 1998-09-04
Abstract: In order to suppress periodic noise, such as from a siren on a public safety vehicle or from a car engine, a speech signal having a periodic noise interferer is input to a speech processor in which the amplitude of the periodic noise is determined 72, a known gaussian noise sequence having the same amplitude as the periodic noise is generated 74 and combined 76 with the (speech + periodic noise signal) so that a standard wide-band noise suppression algorithm can be used in a noise suppressor 78 to suppress both the periodic noise and the gaussian noise. The noise suppressor 78 also provides an input to a sub-band gain adjustment block 80 so that an appropriate amount of the gaussian noise can be subtracted 82 from the output of the noise suppressor 78 to give an output speech signal with a greatly reduced periodic noise content. The arrangement may be used after a speech decoder (50, Fig.3) or in front of a speech encoder 84 in a mobile communications unit.

Title: A method of forming void free trench isolation
Inventor: HONG CHANG-KI
IPC: H01L21/762
Filed: 1999-01-22
Abstract: A method of forming an isolating trench in a semiconductor substrate 30 so as to form void free patterns of isolation within the substrate 30 and to prevent a recess from being generated at side edges of the trench during subsequent etching steps. With the method, a trench forming mask 38 is formed on the substrate 30, in which the trench forming mask is composed of first and second material layers 34,36 having an etch ratio different from each other. The substrate 30 is etched using the trench forming mask 38 to form a trench 40, and then the first material layer 34 is wet-etched to remove both sidewalls of the first material layer 34 and to thereby form an under-cut profile of the trench forming mask 38. Finally, a trench filling insulation layer 44 is deposited over the substrate filling up the trench forming mask 38, wherein deposition speed of the trench filling Insulation layer 44 is slower at the sidewalls of the first material layer 34 than at an interior of the trench. Alternatively, the pad oxide 32 may be etched back prior to trench refilling (figure 3b). In another embodiment a thermal oxide film 54 is provided between the trench oxide field region and the active region, which prevents 'dipping' of the trench oxide during subsequent cleaning stages.
