Title: Method of braking a tractor and trailer or semitrailer
Inventor: TOPFER BERNHARD
IPC: B60T8/32
Filed: 1992-10-19
Abstract: In a method of braking a tractor and trailer (or semitrailer) the ratios of deceleration to the brake pressure, at various load states, of a tractor alone are stored, and, for a tractor and trailer, the trailer brake pressure is controlled such that the actual value of the deceleration which is then set at the prevailing tractor brake pressure, giving due regard to the tractor load state, corresponds to the value, derived from the stored ratios corresponding to the same load state, of the deceleration achieved without a trailer at the same brake pressure of the tractor. A method is also disclosed, in which, when the deceleration derived from the position or actuation speed of a brake pedal is below a set value, the brake pressure supplied to the trailer for a particular duration at the beginning of a braking operation is increased in relation to the brake pressure resulting from the position of the brake pedal.

Title: Variable timing camshaft with variable valve list
Inventor: MADDEN STEPHEN KEITH
IPC: F01L1/352
Filed: 1995-01-05
Abstract: A variable timing camshaft has concentric shafts for mechanically varying the valve timing of internal combustion engines and motors and air compressors and motors. By altering the rotational position of the cam lobes attached to each shaft (1, 2) relative to each other, the valve timing can be varied. This may be achieved by periodically changing the length of a timing chain or belt on one side of sprockets (7, 8). Alternatively, it may be achieved by a series of interconnected cogs which effectively rotate one shaft (1, 2) with respect to the other. The degree of valve lift may also be varied. Inverted cam lobes may act via pivoted rocker arms to open and close the valves. A cam follower spring maintains the tension which is kept to a minimum by means of a spring tensioning device, hydraulic piston lifter or air valve. Alternatively, the relative height of the rocker arm pivot shaft or camshaft can be varied.

Title: Preventing pop noise in TV sound
Inventor: LEE KOK FAH
IPC: H03F1/00
Filed: 1997-02-26
Abstract: In order to quickly decrease the voltage applied to a mute pin 18 of an audio amplifier circuit 19 of an electronic appliance, an end of a capacitor 20 connected to the mute pin is connected to a discharge circuit which is switched on, when the appliance is switched from on to off or stand-by, by exploiting two power supply sources 35, 36 of the appliance. The voltage output of one power source, e.g. fly-back transformer 36, decreases faster than the other power source, e.g. switched mode transformer 35, when the electronic appliance is switched off. An active element 27 of the discharge circuit has an electrode coupled to the first source and another electrode coupled to the second source so that the active element is switched on as soon as the difference between the two output voltages reaches a threshold.

Title: Synchronised updating of interoperating software
Inventor: DONOHUE SEAMUS BRENDAN
IPC: G06F9/445
Filed: 1998-04-24
Abstract: Provided is a method and mechanism for automatic updating of computer programs and synchronising updates of computer programs and their pre-requisite programs to maintain interoperability. Conventionally, computer programs have been distributed on a recording medium for users to install on their computer systems. Each time fixes, additions and new versions for the programs were developed, a new CD or diskette was required to be delivered to users to enable them to install the update. More recently some software has been downloadable across a network, but the effort for users obtaining and installing updates and the effort for software vendors to distribute updates remains undesirable. The invention provides an updater agent which is associated with a computer program and which accesses relevant network locations and automatically downloads and installs any available updates to its associated program if those updates satisfy predefined update criteria of the updater agent. The updater agents are able to communicate with each other and the update process include the updater agent of a first computer program determining whether pre-requisite programs require updating to maintain interoperability and then requesting updates to the first program's pre-requisites programs when required.
