Title: Method for adjusting the spacing of a clothed roller and a clothed surface of a counter element in a spinning preparation machine
Inventor: LEDER ARMIN
IPC: D01G15/28
Filed: 2001-10-25
Abstract: The method, for use in carding machines, cleaning machines etc., comprises the steps of bringing the tips of the clothings 4a,18 of the roller and counter element 14 into contact, ascertaining a reference position in which the clothings are just in contact and then moving the clothings apart from the reference position by a controlled amount.

Title: Method of making a thermoformable liner
Inventor: LAGHI ALDO A
IPC: B29C51/00
Filed: 2002-08-08
Abstract: A custom-fitting prosthetics liner is made without mixing silicone and without making a mold. A thermoformable liner is made by preparing a negative cast from a patient's residual limb, preparing a positive cast from the negative cast, and placing a thermoformable tubular liner over the positive cast. The positive cast and liner are heated in an oven for a predetermined time and temperature. Having acquired a new geometry, the cast and liner are removed from the oven and allowed to cool to room temperature. The liner is then removed from the cast. Alternatively the liner is heated, placed over the positive cast, cooled and removed. The interior surface of the liner conforms to the shape of the cast. The liner is elastic so that it returns to its new geometry when stretched and released. It therefore holds on to a residual limb even when the residual limb shrinks.

Title: Surface modified nozzle plate
Inventor: BEACH BRADLEY LEONARD
IPC: B41J2/14
Filed: 2001-05-02
Abstract: The invention relates to an ink jet printer nozzle plate (10,30,50) containing nozzle holes and having a durable non-wettable layer on at least one surface thereof. The nozzle plate includes a polyimide material and the non-wettable layer contains a derivative of an amine-terminated silane compound, the amine-terminated silane compound derivative being covalently bound to the polyimide material of the nozzle plate. The layer also contains a derivative of a polydialkylsiloxane compound having a number average molecular weight ranging from about 400 to about 150,000 and an end group reactive with the amine-terminated silane compound derivative. The polydialkylsiloxane compound derivative is bound to the amine-terminated silane compound derivative by a condensation reaction to provide the durable non-wettable layer on the surface of the nozzle plate. Because of covalently bonding the silane and polydialkylsiloxane materials to the polyimide, the non-wettable layer remains substantially durable throughout the life of a printhead (120) containing the nozzle plate.

Title: Using a measure of the amount of processing required by a data block to set the performance of the apparatus processing the data blocks
Inventor: STEVENS ASHLEY MILES
IPC: G06F1/32
Filed: 2003-09-17
Abstract: Disclosed is a method for setting the performance control parameter of a data processing apparatus. The apparatus processes a data stream of data blocks. The method of setting the control parameter comprises the steps of performing an initial process on a block and from a result of the process deriving a complexity measure that indicates the amount of processing needed by the block. The control parameter is then set to a predicted value using the complexity measure and the data block is then processed. The control parameter could be the processor frequency and/or voltage, and may be set in dependance of a target time and/or power level. The complexity measure may also depend on a result obtained from processing a preceding block, said result may be a processing time. The data blocks may comprise an image field and frame. The complexity measure may be derived from the features of an image rendering display and may include a count of constituent items. The apparatus may be a graphics co-processor and the images may be 3D. The control parameter may be set by an estimate of the number of memory accesses needed per frame.
