Title: A whiteboard eraser
Inventor: BELL GEORGE CHARLES
IPC: B43L21/00
Filed: 1996-07-02
Abstract: The eraser includes a strip 6 of textile material formed into a closed loop having part of its length embraced by a length of sleeving 8 (eg transparent plastics film).

Title: Walls for ocean wave control
Inventor: VAUGHAN LEONARD THOMAS
IPC: E02B9/00
Filed: 1996-10-04
Abstract: Wave training surfaces in horizontal and vertical curved planes are utilised to control the passage of waves, thus protecting installations from ocean wave action by reducing the wave impact force and in eliminating or reducing a so-called Mach Stem effect which reduces available wave energy in wave energy electrical power generation installations. The surfaces may form part of a breakwater (fig. 1) or walls that channel waves towards a power-generating turbine (figs. 2-4).

Title: Heater control circuit; cooking appliance with cover
Inventor: CARTER MAURICE HUGH
IPC: F24C15/10
Filed: 1996-12-13
Abstract: A hotplate has a plurality of resistive heating elements 2, 3, 4, a knob 6 to select different heat settings, and a control circuit 7 operating such that a maximum of one heating element is duty cycle switched at each heat setting. The elements 2, 3, 4 may have different power ratings (such as 570W, 330W and 300W), which one element is duty cycle controlled being dependent on the selected heating level, and the duty cycle also depending on the selected heating level. The elements which are not duty cycle controlled at a given setting are continuously on or off for that setting, The different heating levels are obtained by a combination of different duty cycles, different elements duty cycled, and different combinations of continuously on and continuously off elements. At some settings there is no element which is duty cycled. If a temperature sensor 8, 9, 10 indicates a temperature below a certain value when a heat setting is selected, the energy input to the hotplate is set to exceed the normal value for that setting for a time dependent on the selected heating level. A neon light 11 is turned on to indicate that the hotplate is too hot to touch. The hotplate may have an at least partially transparent, bowl shaped, removable cover (13, Figs.2A, 2B), the cover and hotplate defining a region into which food may be placed for cooking.

Patent GB-2308898-A (GB)
Title: Adaptive nonlinear controller for electromechanical or electroacoustic system
Inventor: KLIPPEL WOLFGANG JOHANNES HUBE
IPC: H04R3/00
Filed: 1996-12-20
Abstract: This invention comprises an arrangement for controlling an electromechanical or electroacoustic system 2 (eg for reproducing music or speech, for generating vibration, or for active cancellation of noise or sound) so as to produce a desired relationship between the electric input 14 and a mechanical or acoustic parameter in said system. The arrangement comprises a sensor for measuring the parameter, means for generating an error signal by comparing the measured parameter with a desired value and a nonlinear controller which generates a correction signal, 84, for addition, 32, to the electric input signal, to minimise the error signal. The nonlinear controller comprises linear adaptive filters, 68, 72, and at least one static nonlinear element, 70. The adaptive adjustment of the linear filters is constrained so that the magnitude and/or phase and/or group delay response is predefined with respect to a frequency independent factor so as to ensure a convergence to a unique solution. The use of linear filters with a constrained adaptive adjustment prevents limiting of the signal and loss of numeric resolution and leads to an optimal filter adjustment.

IPC: B63H9/06
Filed: 1998-10-16
Abstract: A sail rig of a single approximately triangular sail held between a yard 2 and a boom 3 attached to and pivoted below the yard 2 before the forward end thereof. The yard 2 is pivoted on top of a stub mast 7,8 between the forward end and the junction 4 with the boom 3, and the vertical angle of the yard 2 is controlled by a halyard 6 between the forward end of the yard and the stub mast 7,8.

Title: Line testing in a telecommunications network
Inventor: MULCAHY CHRISTOPHER JOHN
IPC: H04Q3/72
Filed: 1998-04-07
Abstract: A centralised test apparatus (18) is provided for a telecommunications network which includes local switches (12, 16) and a core network (14). Each local switch is connected through terminating lines to terminal equipment such as telephone instruments. The test apparatus (18) enables a field engineer to record routing data in a centralised database (19). When a field engineer connects a telephone instrument to a terminating line in a node in an access network, the engineer can dial the number of the test apparatus (18). The test apparatus retrieves the calling line identity on answering the call. It then invites the field engineer to enter an identifier for the type of node, the number of the node and the number of a terminal inside the node through which the terminating line passes. The calling line identity, the type of node, the number of the node and the number of the terminal are then used to update routing data in the database (19). Thus, the invention provides a method of updating and maintaining routing data.
