Title: Device for drawing arcs of circles.
Inventor: ADAMS JONATHAN GWYN
IPC: B43L9/00
Filed: 1991-05-14
Abstract: The device comprises a chassis divided into two sections (16, 17) with wheels (19, 20) fixed to each section thereof. Each wheel revolves independently of the other wheels. The two chassis sections are joined by a pivot (18) with a clamp screw allowing the angle between the two sections to be continuously adjustable and fixable. A callibrated scale (21), together with a clock vernier (23), shows the angle between the two sections of the chassis. The angle is proportional to the radius of the arc defined by the device as it is propelled across the working surface. A pen/pencil holder (26) is provided on a linear scale (27). <IMAGE>
Patent GB-2256444-A (GB)
Title: Foldable structure
Inventor: BURDON ROBERT LAXTON JOHN
IPC: H01Q1/12
Filed: 1991-05-25
Abstract: The drawings show a node and link module which can be assembled with similar modules to provide a foldable structure of any desired size. The module has four upper nodes (1a, 1b, 1c and 1d) and four lower nodes (2a, 2b, 2c and 2d). To assist in differentiating between the two sets of nodes, the upper nodes (1) are shown shaded. Upper node (1d) has been omitted from the figure for clarity. The node (1d) is pivotally connected by links (3) to each of the lower nodes which is adjacent to the lower node (2d) lying opposite to node (1d). Node (2d) is similarly connected by pivotal links (3) to each of the upper nodes surrounding node (1d, i.e. 1a, 1b and 1c). The structure thus presents a double tripod of considerable strength. The effect of the pivotal link connections is that the structure can be freely moved between an expanded condition and a folded condition. In the folded condition the upper nodes (1) are grouped together and the lower nodes (2) are grouped together, the two groups being spaced apart by a distance which is almost equal to the length of the links (3). The structure can be moved from the folded condition to the expanded condition by moving nodes (1) towards the nodes (2). As the nodes (1) move towards the nodes (2) the compressive force supplied by the link (3) forces the nodes (1) and the nodes (2) to spread out to the positions shown in the figure.

Title: Electromagnetic bead core filter manufacture
Inventor: YI HYUNG-JIN
IPC: H01F27/02
Filed: 1991-07-31
Abstract: An EMI bead core filter to suppress noise has an impedance which increases with frequency, and comprises a ferrite core 3, a wire 7 and an epoxy powder coating layer P. The layer is deposited on the upper portion of the core 3 and on a bend portion 8 of the wire to adhere the core and the wire. The filter is produced by bending the wire 7 and then inserting it into the core 3 to form a prefilter 1' which is supported on a tape 11, 13. The portion 8 of the prefilter 1' is then heated and coated with epoxy powder from a chamber 27. The filter is then packaged and hardened. The coating is accomplished by heating at 380 DEG C initially, and then at 335 DEG C to 340 DEG C for three more times. <IMAGE>

The sensor may be arranged so that the temperature it senses is the average of the temperatures of more than one pusher. The conveyors may alternatively be endless belts with heating elements located on the side of the belt opposite to that which contacts the wrapped articles. <IMAGE>

Title: Power factor correction converter
Inventor: WHITTLE REX WILLIAM JAMES
IPC: H02M1/00
Filed: 1992-02-27
Abstract: A boost-type power factor correction converter is disclosed in which the output voltage of the converter is proportional to the peak, average or RMS value of the input voltage. The circuit includes a peak rectifier D2, C2 which senses peak input voltage and provides a reference to which the output voltage derived through resistors R3, R4 is compared at 102 to give an error signal dependent upon variation from the peak input voltage derived reference. The error signal is used to control a MOSFET switch 120 by means of a multiplier 104 and a modulator and gate driver 106 so as to adjust the duty cycle of the switch 120 and to provide an output voltage Vout dependent upon the reference. An FET inverter (Fig 5) having an output rectified to provide a DC output may be connected to the converter. <IMAGE>

Patent GB-2259625-A (GB)
Title: Motion vector assignment to video pictures
Inventor: BORER TIMOTHY JOHN
IPC: H04N5/14
Filed: 1992-09-30
Abstract: To determine whether any of a menu of motion vectors applies to any given pixel, both forwards and backwards assignment operations (64, 66) are undertaken. Each current picture is shifted (50) by each of a plurality of possible motion vectors and compared (52) to a succeeding picture to determine assignment errors for each pixel. The succeeding picture is also shifted by each of a plurality of possible inverse motion vectors and compared to the current picture to determine assignment errors for each pixel. The assignment errors are combined (62) and if either of the assignment errors for a pixel is large, that pixel is flagged "no match".
Patent GB-2268287-A (GB)
Title: Electric window safety system
Inventor: TAKEDA HITOSHI
IPC: H02H7/085
Filed: 1993-06-22
Abstract: In a window system having a safety mode whereby motion is reversed when an obstacle is encountered 116, the safety mode is disabled when the window is nearly closed thus preventing erroneous actuation eg when the window meets the seal. Reliable operation is ensured by measuring the position of the window directly 113 rather than by determining the position from the motor output. In the safety mode, window motion is reversed when the motor speed falls below a reference level thus indicating the presence of an obstacle. In an alternative embodiment (figure 12) the reference value is variable 42 in dependence upon the detected window position. <IMAGE>

Title: Expert system for presenting multimedia information in a tree structure.
Inventor: SPOTO THOMAS A
IPC: G06F3/048
Filed: 1993-09-07
Abstract: The system uses multimedia information tools (i.e. graphics, documentation, drawings, photographs, full motion video with audio, PLC ladder, etc.) and techniques to assist maintenance personnel. Diagnostic development and multimedia information assignment are accomplished through graphical visual programming, which requires no conventional software programming. The system uses diagnostic trees having multimedia graphic icons which define the diagnostic components. In developing a visual diagnostic tree, the multimedia information can be assigned or mapped to each node of the tree by selecting an appropriate icon to represent the multimedia from an icon library. Then, an appropriate media information file or record and comments for that icon are added. The system uses conventional hardware and can be used on the plant floor. <IMAGE>
