Patent GB-2047939-A (GB)
Title: Capodastro
IPC: G10D3/04
Filed: 1980-04-21
Abstract: A capodastro for stringed musical instruments, has a pressure bar C whose lower face L has two roughly parallel long edges I, K. Edge I is straight, and edge K is vertically concave. The concavity at edge K complements the maximum convexity normally found transversely on the fingerboards of stringed musical instruments. The longitudinal contour lines of face L increase in curvature gradually from straight edge I to curved edge K. In one version face L is smooth. In a second version face L bears a number of longitudinal ridges. The lower face L of pressure bar C is thus adapted to press equally on all the strings whether the fingerboard be flat or convex. <IMAGE>

Title: Unitary Electromagnet for Double Deflection Scanning of Charged Particle Beam
IPC: G21K1/093
Filed: 1980-05-20
Abstract: A unitary electromagnet having two gaps is provided for the double deflection scanning of a charged particle beam. The unitary electromagnet 10 is configured to permit traverse by said beam through the gaps 13, 14 in a plane defined by the gaps of opposite polarities. The depth of the gaps is large as compared to the length to accommodate the scan of the beam. The mode of scanning is determined by the waveform used to energize the windings of the electromagnet and includes axial sweep scanning, off center scanning and split scanning (Figs. 2-4, not shown). Neutral particles may bombard one spot of the wafer area (Figs. 3A, B), and alternate stations scanned (Figs. 4A, B). The arrangement counters variable angles of incidence at the target in ion implantation systems for example. Scanning by e.s.-e.m. combinations, and by rotation of target and double deflection scanning is described, uniform dosage in the latter instance being by variation of traverse scan rate or beam intensity. Gap lengths are preferably equal; dimensions are exemplified. <IMAGE>

Patent GB-2090402-A (GB)
Title: Measurement of temperature by radiation pyrometry
IPC: G01J5/00
Filed: 1981-12-24
Abstract: It is desired to measure the true temperature of surfaces of test objects by purely radiation pyrometric means, without the existence of prior information concerning either the emissivity of the surface of the object to be measured, or the space occupied by the object to be measured. Measurements are made over a broad spectrum of the temperature radiation of the surface of the test object by an interferometer arrangement, and are evaluated by a computer by means of a search algorithm to identify regions where the emissivity is independent of or linearly proportional to, wavelength, whereupon temperature can be deduced from the measurement corresponding to such regions. In an expanded variant, an additional auxiliary radiator is used whose radiation reflected from the surface of the object to be measured is jointly evaluated. The invention is particularly suitable for research work or for preliminary investigations for the use of temperature measuring devices in technological processes.
