Title: Delayed switch-on device
Inventor: LANE RICHARD JOHN
IPC: G05D23/275
Filed: 1987-08-11
Abstract: A storage heater incorporates a device which is operative to delay the onset of charging of the heater subsequent to the commencement of an off-peak period of the electricity supply. Problems associated with the additional demand for electricity immediately subsequent to commencement of the off-peak period can thus be reduced. The delay device may comprise a metal block 8 of high heat capacity which is heated by an element 10 when the off-peak supply is connected. When the block 8 attains a predetermined temperature, a bellows 18 causes an arm 14 to close a switch A to connect the storage heater to the supply, and a changeover switch B is also operated to de-energise element 10 and energise an element 12 of lower power than element 10. The device may be settable, eg by adjustment means 20 or by changing the power rating of element 10, to give a delay of 45 to 75 minutes. <IMAGE>
Patent GB-872160-A (GB)
Abstract: 872,160. Gramophone pick-ups. CLEVITE CORPORATION. Feb. 9, 1959 [Feb. 10, 1958 (2)], No. 4411/59. Class 40 (4). [Also in Group XL (b)] An electromechanical transducer element capable of simultaneous two-channel operation and particularly applicable to stereophonic recording and/or reproduction of sound on record discs is characterized by an elongated hollow body of radially polarized ferroelectric ceramic material having a longitudinal axis of symmetry and a plurality of electrodes forming three terminals, and in that the direction of polarization and arrangement of said electrodes are such that the maximum electrical potentials at two of said terminals with reference to the third terminal are associated with perpendicular planes of flexural deformation of said body. In the pick-up shown in Fig. 1, a tubular ceramic body, e.g. of barium titanate or lead zirconate titanate, is mounted on a flexible shaft 12 secured to a support 16 and provided with a stylus point 14. The body 20 is provided with external electrodes 22, 24, 26 and 28 and an internal electrode 30 and is polarized as indicated by the arrows P in Fig. 4. The electrodes are connected as shown to three terminals A, B and G. The external electrodes may be connected together by conductive strips applied to the body 20 and the connection to the internal electrode 30 may be made through the conductive surface of the shaft 12. Flexure of the body 20 in the vertical X-X<SP>1</SP> plane produces a maximum potential at terminal B with respect to terminal G and a minimum potential, effectively zero, at terminal A, while flexure in the horizontal Y-Y<SP>1</SP> plane produces a maximum potential at terminal A. Flexure in other planes produces respective potentials at terminals A and B which are proportional to the respective vector components of the displacement in the planes X-X<SP>1</SP> and Y-Y<SP>1</SP>. Two stereophonically related tracks, one " hill and dale " and the other " lateral " may thus be recorded or reproduced simultaneously. In an alternative embodiment, Fig. 9, the polarity of the polarization P is uniform around the body 20 and the connections to the terminals A, B and G are modified accordingly. Further alternatives comprise arranging the planes X-X<SP>1</SP> and Y-Y<SP>1</SP> at 45 degrees to the plane of the record disc and making the body 20 of square or other polygonal cross-section.

IPC: G01P5/26
Filed: 1990-10-19
Abstract: Particle size and velocity monitoring apparatus comprises means 12, 14, 16, 20 which creates two coherent light beams which intersect to define a probe volume 18, and at least one sensor detecting light scattered by a particle traversing the probe volume. Each sensor comprises a beam splitter 30 arranged to split the scattered light into two components and two photodetectors 34 to detect these components. The polarisation of the intersecting beams and the polarisation created by splitter 30 are such that the Doppler signals in the two components are 180 DEG  out of phase. The detected signals are added (to give a pedestal) and are subtracted to give the Doppler signal. The Doppler frequency indicates particle velocity, while the ratio of the Doppler signal to the pedestal signal indicates particle size. A second sensor may be used, as shown, in which case the phase difference between Doppler signals at the two sensors indicates particle size. The pedestal signals may be utilized as trigger signals. <IMAGE>

Title: Multi-directional hand scanner and mouse
Inventor: CHIU WING-LIM
IPC: G06F3/033
Filed: 1991-03-04
Abstract: A manually operated scanning device which functions as a computer input device, called a mouse, and as a hand scanner for copying printed material. The scanning device includes first position sensor 116 which generates X and Y position information and a rotation sensor 118, separate from the position sensor, for generating scanning device rotation information. The scanning device periodically transmits to a computer a representation of visually perceptible information from the object being scanned and the position and rotation information of the scanning device when the visual information representation was generated. The visual information representations are stored in a pixel array of the computer in storage locations identified by the position and rotation information. Advantageously, visual information representations received by the computer are compared to selected pixel array information to correct for positioning errors prior to storage of the received information in the pixel array. It is possible to use the device repeatedly to scan and, if necessary, rescan parts of the original, in any direction, to build up a complete image. <IMAGE>
