Title: Electric heater and control assembly, particularly for a transparent vessel
Inventor: TAYLOR JOHN CRAWSHAW
IPC: H05B1/02
Filed: 1999-03-17
Abstract: An integrated electric heater and control assembly, suitable for a liquid heating apparatus such a cordless kettle, comprises a heater having a primary heating track 23 and a secondary heating track 87. The tracks may be laid down by thick film techniques on a mild or stainless steel disc which is provided with an insulating layer 22 and forms the base of a vessel. When the heating apparatus is activated by the user, the liquid in the vessel is brought to the boil by the primary heating track 23, which may have a power of 2.2kW. Boiling is detected by a thermally-sensitive actuator which turns off the primary heating track. Once the liquid has reached boiling temperature, it is maintained at this temperature by the secondary heating track 87 alone, without the use of any form of thermostatic control. The secondary heating track may have a power of 25 - 30W. The heating effect of the secondary heating track is substantially localised so that a stream of bubbles, which may be viewed through a transparent vessel, will rise from the region of the heater. Also disclosed are activation of the heater by means of rotational movement of the vessel, such movement being detected by bobweights, and other novel constructional features.

Title: Photosensor assembly with line arrays of sensors of different sizes
Inventor: SPEARS KURT E
IPC: H04N5/369
Filed: 2001-10-19
Abstract: A photosensor assembly for an optical image scanner has line arrays of photosensors of a first size (102,116,130), and line arrays of photosensors of a second size (112,126,140), with the two sizes being different. Charge shift registers (106,120,134) receive charges transferred from the arrays. An array of photosensors of the first size (102) and an array of photosensors of the second size (112) receive light of the same colour band and transfer charges to the same charge shift register (106). The photosensor assembly may be configured so an overflow drain (114) can receive overflow charges from separate arrays (112,116) having sensors of different sizes. The photosensor assembly may include arrays of photosensors arranged in a staggered pattern (212, Fig. 2). A method of scanning is also disclosed, where two arrays of photosensors (102,112) are exposed to light of the same colour band, and charges are transferred to a charge shift register (106) from both arrays, with charge transfer occurring at a different optical sampling rate in each array.

Title: A start-up circuit for a CMOS crystal oscillator, in which the initial bias current is readily determined
Inventor: MAEDER HEINZ
IPC: H03B5/32
Filed: 2003-03-07
Abstract: The bias current Ibias provided by M3 for the amplifier M1, M2 in a crystal oscillator is initially high but is automatically reduced as oscillation builds up. The stacked and cross-coupled amplitude detecting transistors M5-M8 allow a significant drain current to flow only when the oscillation amplitude is low because as amplitude builds up, there will be a relatively low voltage on one or other of the stacked devices in each branch during most of the oscillation cycle. The reduced drain current of M5-M8 results in a lower drain current through M4 and hence a lower bias current in the mirror transistor M3. The start-up current is well-defined as a function of the reference current in Rbias and two current mirror ratios. There may be only one transistor stack M5,M6 or M7,M8.

A control circuit 30, which effectively combines the two antennae 15,20 into one antenna, comprises phase shift circuits 45,50 which can be transmission line networks or lump inductive and capacitive networks. The phase shift circuits prevent the first antenna 15 from operating at the third and fourth frequencies and the second antenna 20 from operating at the first and second frequencies. Excessive VSWR is eliminates and power consumption is reduced.

IPC: B26D5/02
Filed: 2003-09-22
Abstract: A die cutting apparatus 10 comprising an anvil 40 , a first rotary die cutter 32, a secondary die cutter 34 and a rotatable frame 30. The frame carries the first and second die cutters such that they are in rolling engagement with the anvil. A web of process material 60 passes through a nip between the anvil 40 and the first rotary die cutter 32 when the die cutter is in its operative position, thus cutting the material. If it is desired to cut the material into a different configuration, or to use a material of a different width, or simply to replace the die cutter, the frame 30 can be rotated to bring the second rotary die cutter 34 into its operative position, in place of the first die cutter 32. The apparatus may include more than two rotary die cutters, provided that when in a non-operative position, they do not interfere with the flow of the process material (60) through the apparatus.

Title: Feedback slew rate stabilisation for a CMOS output driver subject to PVT variations
Inventor: CULLER JASON HAROLD
IPC: H03K5/00
Filed: 2004-05-10
Abstract: The output slew rate of a CMOS driver 385 is stabilised by feedback to counteract variations in fabrication process, supply voltage, or temperature (PVT). The output slew rate is measured using threshold circuits 410,430 and a counter 450 (figure 4). The counter output selectively switches into circuit a set of capacitors 340-370 which control the slew rate of the predriver node and hence the slew rate of the output node. The impedance of the output driver circuit is not altered when the slew rate is changed.

Title: Information retrieval apparatus for processing a query for retrieval of information from a database
Inventor: BACLAWSKI KENNETH P
IPC: G06F17/30
Filed: 2000-03-29
Abstract: An information retrieval apparatus for processing a query for retrieval of information from a database has a mechanism for locating a number of features and feature fragments in an index database; an evaluating mechanism for identifying a number of sub-queries of a number of levels contained in the query and recursively evaluating the sub-queries using each of the located features and feature fragments; and a mechanism for collecting and storing a number of results of the recursive evaluation of the query and sub-queries pursuant to computing an overall result of the query. Such a system can eliminate the need of conventional retrieval systems for providing a new, separate, centralized replica within the data warehouse of the data stored in the diverse external databases. The invention can thus avoid the problems of replication of such data in conventional systems, in which the data may become stale or is subject to errors arising during replication for warehousing. Instead, the data warehouse can contain an index database, which stores entries providing data regarding the information stored in the external databases, such as information location specifiers for that data within those databases, relational information and statistics. The invention can also provide a robust, versatile indexing system.

A heat exchanger 24 may be arranged between the vessel and the pump to cool the barrier fluid. A Thermostatically controlled outlet valve 25 may be provided to vent barrier fluid from the vessel when the temperature exceeds a predetermined temperature. The detector 20 will then sense the fall in fluid level and open valve 22 to replace the lost fluid from a source of barrier fluid at a lower temperature.
