Patent GB-2006520-A (GB)
Title: Piezo-electric resonator
IPC: G04F5/06
Filed: 1978-09-06
Abstract: In order to improve the resonance frequency-temperature characteristic of a resonator (51) for an electronic timepiece, the resonator (51) is arranged to have a plurality of different modes (52, 54) of vibration which are coupled to each other. As shown, a flexure mode (52) on the X'Y' plane is coupled to a torsional mode (54) about the central axis. Other specified couplings are thickness-shear/face-shear, thickness- shear/flexure, and two perpendicular longitudinal or flexural modes, and higher harmonics may be used. The required modes are achieved by appropriate crystal cutting angles and electrode arrangement. <IMAGE>

Patent GB-2034543-A (GB)
Title: Fluorescent lamp starting circuit
IPC: H05B41/04
Filed: 1978-11-10
Abstract: A circuit for starting a fluorescent lamp comprises a capacitor C12 connected in parallel with a thyristor S1. When the lamp is connected to a power supply, a trigger circuit T1 fires the thyristor to conduct heating current through the lamp filaments. Due to the inductive nature of the circuit, the thyristor is switched off near each peak of the supply voltage so that a high voltage pulse is supplied to the lamp by the capacitor in each cycle of the supply voltage. When the lamp fires, the voltage across the lamp is reduced, preventing further operation of the starting circuit. The thyristor may be a triac triggered via a diac. <IMAGE>

Title: A magnetically operated switch for a telephone instrument
IPC: H04M1/10
Filed: 1979-01-16
Abstract: A switch 33 is actuated when a shunt 25, 29 is deflected to expose the switch to flux from a magnet 31. The switch 33 is also operated by a magnet 37 in a telephone handset 3 when this is cradled on the base 1. When the handset is removed from the base the switch signals the off- hook condition. A button 21 by pivoting the shunt 25, 29 allows an on-hook condition to be signalled without the need to replace the handset. <IMAGE>

Title: Method of and device for determining a radiation absorptio distribution
IPC: G01N23/08
Filed: 1980-03-12
Abstract: The invention relates to a method of and a device for determining a radiation absorption distribution in a part of a body. Per measuring value a contribution of the absorption value in each element of a matrix imagined in the part is calculated. It is demonstrated that this contribution equals the value of the measuring value multiplied by a weighting factor. The weighting factor is a function of the distance between the element and the measuring path along which the measuring value is determined. A calculation method of this kind enables fast on-line calculation of an absorption distribution and the complete reconstruction of the absorption distribution is laid down in a hardware circuit. Complex operations such as F.F.T., convolution and interpolation are not required.

Title: Equipment for the delivery of slurry and refinement during delivery
IPC: B01F5/00
Filed: 1980-05-09
Abstract: A House (1) provided with an axial inlet opening (4) and a tangential discharge opening (5) contains a disc-shaped stationary part (3) with a concentric opening (3') adjoining the inlet opening (4) and a disc-shaped rotary part (2) arranged opposite the stationary part (3). Rods (9, 7) are concentrically arranged, alternately on the stationary part (3) and rotary part (2) in such a way that the rods of each part point toward the other part. The rotary part (2) has a jacket (6) surrounding the outermost rods (9) of the stationary part (3), said jacket being perforated with holes (6) in radial direction. The rod-lines of the stationary and rotary part, as well as the jacket of the rotary part and their holes bring about an intensive turbulence, resulting partly in powerful impact and friction between the solid particles of the slurry and partly in cavitation, which initiate the explosive disintegration of the particles. At the same time the refined slurry arriving at the discharge opening, has a high exit velocity, whereby the lift of the equipment is unusually high. <IMAGE>

Title: Video display terminal for simultaneously displaying graphics and alphanumerics
IPC: H04N1/21
Filed: 1980-06-04
Abstract: A video display terminal may simultaneously display graphics generated by a camera and alphanumerics on the same screen. Data may be inputted by way of, for example, a keyboard or host computer, and stored in a read/write memory, such as a random access memory (RAM). In addition, graphics picked up by a closed circuit TV camera may be dynamically displayed on the terminal screen in real time then frozen and transmitted to a remote location, such as a host computer, for long term storage. The static graphics thus recorded can be called up and redisplayed on command at the same or a different video display terminal communicating with that host computer. Alphanumeric information associated with that graphic image may also be entered at the terminal and recorded at the host computer. Both the graphics and alphanumerics may then simultaneously displayed in superimposed relationship, if needed, on a video display terminal. An application of this system is in signature verification. <IMAGE>

Title: Detection or particles containing predominantly low atomic number nuclei
IPC: G01N23/20
Filed: 1980-06-25
Abstract: A method of detecting desired particles, e.g. diamonds, containing predominantly atomic nuclei having low atomic numbers in a particulate material including other particles containing atomic nuclei having higher atomic numbers, includes the steps of irradiating particles, advantageously individually, of the particulate material with incident X-rays, conveniently in the form of a monoenergetic beam, to produce scattered X-ray spectra for said particles, determining the peak strengths due to Compton scattering and/or Rayleigh scattering of the incident X-rays by the particles, at a selected scattering angle (preferably an angle other than one at which a Bragg peak [coherent diffraction peak] occurs for the desired particles in polycrystalline form) relative to the incident X-rays, and utilizing the peak strength information to identify said desired particles. Preferably, for diamond, the ratio of the Compton peak to the Rayleigh peak is used, as being substantially greater for diamond than for non-diamond specimens.
