Title: Internal combustion engine ignition system
Inventor: DIXON STANLEY JOHN
IPC: F02P17/12
Filed: 1996-11-11
Abstract: In a combined heat and power system including a reciprocating internal combustion engine fuelled by gas and operating at a substantially constant speed and at a substantially constant air to fuel ratio, the engine has spark plugs 16, 18, 20 and 22 each having a pair of electrodes 12, 14 with a gap therebetween. Each plug is connected to a spark generator and distributor device 44 by which electrical energy is supplied to each spark plug in turn. Operation of this spark generator and distributor device 44 is under control of an ignition spark duration control 10 whereby the duration of an ignition spark between the electrodes of the plug 16 is automatically variable to bring the spark duration closer to a predetermined minimum duration over which there would be supplied to the electrodes of the plugs in turn a minimum level of electrical ignition energy to substantially avoid misfire in the cylinders. The minimum level of the electrical ignition energy is variable according to the size of the gap between the electrodes. The duration of the ignition spark of the plug 16 is observed by a monitor 62 in the lead which inputs the observed duration time into the control 10.
Patent GB-2321577-A (GB)
Title: Compression decoding and re-encoding
Inventor: WELLS NICHOLAS DOMINIC
IPC: G10L19/16
Filed: 1997-01-27
Abstract: An auxiliary data signal is derived from a received compression encoded audio signal during decoding of the signal and communicated with the decoded audio signal for use in re-encoding the signal. The auxiliary data signal may be communicated integrally with the audio signal, for example in the least significant bits, or may follow a different path. The provision of the auxiliary data signal may enable more transparent decoding and re-coding processes to take place, by allowing the coding decisions to match the coding decisions originally used; this can alleviate problems with quality reduction arising from cascaded decoding and re-coding processes. Application is to digital broadcasting in the studio environment with mixing, fading, etc.

Title: Ferrofluid to combat oil slicks
Inventor: KIM TAE OK
IPC: C02F1/68
Filed: 1997-06-11
Abstract: A ferrofluid for removing oil from a water surface is prepared by adsorbing surfactant pref. sodium oleate on the surfaces of magnetic particulates such as magnetite (Fe 3 O 4 ) particulates prepared from an acid waste solution; preparing a dispersion of said magnetic particulates by dispersing said magnetic particulates with the surfactant adsorbed into an organic solvent; pref. crude oil kerosene, cyclohexane etc. and adding an amphipathic non-ionic surfactant to said dispersion of the magnetic particulates. A preferred non-ionic surfactant is polyoxyethylene nonylphenyl ether. The ferrofluid has an improved power to disperse oil on a water surface. By using such ferrofluid and an oil slick drawing apparatus equipped with the permanent magnets, the oil can be selectively and effectively removed and recovered without adversely effecting the ecosystem of the sea.

Title: Automatic switching of a headset/speaker between a telephone and a second audio source
Inventor: IGLEHART DAVID
IPC: H04R3/00
Filed: 1997-10-22
Abstract: A single headset 110, or speaker, is used with both a telephone 114 and a second audio source 112, such as a CD player or tape recorder music source or a computer running a multimedia presentation. The headset 110 is normally connected to the audio source 112 and is automatically switched to the telephone 114 when a detector in a changeover switch 102 senses that a voltage on the telephone line is greater than a threshold. This voltage is present when the telephone goes off-hook in response to the user taking the telephone off-hook or operating a button or switch. The arrangement may be included in computer systems as part of a telephony board. In an automobile, a cordless telephone and an audio device could use the same speaker.

Title: A method of fitting a security device to a hinged panel and a security device therefor
Inventor: WELLMAN DAVID ANTHONY
IPC: E05D11/00
Filed: 1998-03-25
Abstract: The invention is concerned with a method of fitting a security device to a hinged panel, and a security device therefor. According to the invention an elongate peg or pin (20) is mounted preferably on the hinged side of the frame (10) surrounding the panel (14), whereby it corresponds with a recess (22) in the panel. The pin is mounted on the frame by creating an aperture through a part of said frame, and then driving the pin through the aperture so that the end closest to the panel is received in the recess when the panel is in the closed position. The method of fitting the security device may include the step of drilling an aperture through the hinge edge of the frame and into the frame edge of the panel. It is also disclosed that the relative positions of the recess and pin can be reversed, so that the pin engages with a recess in the frame member. The frame can be any one of a number of different types, and may have a reinforcing member through which the aperture and pin passes.

Abstract: A processor including in-circuit emulation means comprising a plurality of scanchains of serially connected registers coupled to a means for enabling a serial scan procedure to be carried out, a first scan-chain including an address register 16 for providing an address on an address bus to synchronous memory 14, and means for incrementing the value in the address register under the control of the processor, the scan-chains being arranged to control the processor for incrementing the address register. A second scan-chain includes a data register (84, Figure 2) coupled to the data bus (91) of the memory to read/write data. The output of the address register 16 is coupled to an incrementer coupled via an address multiplexer (102) which is controlled by the microcode register 12. The multiplexer has an assigned bit (100) for controlling its state to ensure that a new instruction cannot be entered in the microcode register whilst address incrementing is occurring. Memory access throughout debugging is made practicable by minimising the number of operations needed for each access.

Title: Method for manufacturing an antenna body for a phone
Inventor: PONTOPPIDAN MORTEN
IPC: H01Q5/371
Filed: 1998-12-23
Abstract: A dielectric body 40 for use as an antenna body in an antenna device, eg a cellular or cordless phone, is manufactured using a two shot injection moulding process. The first step of the method involves the formation of a first part of the dielectric body (100; figures 11,14) by injection moulding wherein a first resin is injected into a first cavity in an injection moulding tool. Then this first part is moved to a second cavity in the injection moulding tool, the first part acting as a core as a second resin is injected into the second cavity to form a composite dielectric body (100,110; figures 11,14). One of the resins, preferably the first resin, is a metal-repelling resin, and the other resin, preferably the second resin, is a metal-attracting resin, such that metal adheres to it in a subsequent metal-coating process. The metal-repelling resin is preferably a crystalline polystyrene, and the metal-attracting resin is preferably a compound polymer comprising a crystalline polystyrene with an appropriate catalyst. The antenna device uses a separate metal shield (24; figures 4,5) as ground plane, the metal shield being attached to the antenna body.
