Patent GB-2176915-A (GB)
Title: Control of magnetic drive system
Inventor: JONES MEIRION
IPC: B01F15/00
Filed: 1986-05-20
Abstract: A magnetic drive system in which a prime mover eg. an electric motor, is magnetically coupled (but not mechanically coupled) to a magnetic follower eg. a stirrer, is controlled by detecting, at intervals, a variable which gives a quantitative indication of the energy output of the prime mover eg. motor current. The energy output of the prime mover is reduced by a predetermined proportion (such as about 10%) each time the magnitude of the variable decreases by more than a predetermined amount between successive detection instants. The system ensures that magnetic coupling between the motor and stirrer or other magnetic follower is maintained at high speed by keeping the motor current constant. <IMAGE>

Title: Measuring contrast range of an image
Inventor: HEARD MAURICE CLIFFORD
IPC: G01J1/42
Filed: 1986-09-13
Abstract: The contrast range and, preferably, also the exposure index of an image projected by, e.g., a photographic enlarger is measured using a hand-held sensing head. This has a mirror 4 for deflecting the light from the enlarger into two closely spaced ends of respective optical fibres 5,6. The other ends of the fibres are connected to photo-sensors 7,8. Processing circuitry 10 compares the outputs of the photo- sensors and, whenever a significant change is detected as the head is swept by hand repeatedly over the image, one of the outputs in stored in a memory. The contents of the memory are analyzed, when a sufficient number of outputs have been stored in order to determine the contrast range and, preferably, also the exposure index. The contrast range and exposure index may be displayed or used to control a printing operation automatically. Instead of using a hand-held sensing head, the image may be remotely scanned by a telescopic system. <IMAGE>
Patent GB-2181600-A (GB)
Title: PC-board mounted thermal switch
Inventor: MERCHANT DONALD K
IPC: H01H61/04
Filed: 1986-10-07
Abstract: A PC-board mounted thermal switch that opens with a snap action includes a bimetallic element 30, connected to a load terminal 6 and resting on an insulated sawtooth surface 36 when contacts 28,38 are in the closed position. A contact blade 20 connected to a line terminal 4 is pivotably biased downward into electrical contact with the bimetallic element by the action of an overcenter spring 26. An overcurrent through the breaker heats the bimetallic element 30 directly and causes it to bend upwardly, forcing the contact blade 20 to pivot against the bias of the spring. When the contact blade has pivoted sufficiently to move the spring overcenter, the direction of spring bias reverses, pivoting the contact blade rapidly upward, and thereby opening the contacts with a snap action. The housing provides an access aperture 56 to the load terminal 6 for adjusting the position of the bimetallic element 30. <IMAGE>

Title: Method of compressing halftone image data
Inventor: ISHII HITOSHI
IPC: G06T9/00
Filed: 1989-06-02
Abstract: The method is applicable to an image filing system, facsimile or similar system for recording data representative of a halftone image by compressing the data and reconstructing the compressed data. In an input (12) two-dimensional halftone image, the coordinates points where a difference of density changes in the x direction are determined to produce an x direction transition point pattern (18) associated with the coordinates. A y direction transition point pattern (20) is produced by effecting similar processing in the y direction. Further, an AND pattern (22) of the x direction and y direction transition point patterns is generated. The pixels based on the AND pattern are determined to be the characteristic density and are coded, (24) the densities of the other pixels being calculated at the time of decoding. The transition patterns are individually coded by transforming the differences of density data into Huffman codes. …<IMAGE>…
