Abstract: 1,246,443. Lasers; resistors. FERRANTI Ltd. 15 Aug., 1968 [23 Aug., 1967], No. 38816/67. Headings H1C and H1S. [Also in Division C7] In a coating process wherein material is deposited from a gaseous atmosphere on to selected areas of a substrate, the said selected areas are irradiated using a laser, the duration and intensity of the irradiation being such that the temperature of these areas exclusively is high enough to cause deposition of a layer of material of the desired thickness. The laser may be a pulsed-output ruby laser emitting light in the I.R. or visible red region of the spectrum, and the selected areas are defined by using a phase- or amplitude-variable hologram. The process may be used for making thin-film carbon resistors. In the Figure, a chamber 12 has an alumina substrate placed on base 10, and following evacuation through pipe 15, benzene vapour is admitted through pipe 13, possibly together with diluent argon from 22. Radiation from pulsed-output ruby laser 17 and co-operating phase-variable hologram 18 passes through bloomed window 20 so that selected areas of surface 21 of the substrate are heated sufficiently to cause deposition of carbon thereon in narrow zig-zag configurations, which, after separation from each other with a scribing tool constitute thin-film resistive elements.

Abstract: 894,730. Measuring gravitational forces. LUNDBERG, H. T. F. Nov. 16, 1959, No. 38824/59. Class 97(3). An instrument for measuring derivatives of the earth's gravitational field comprises at least two equal masses 15, 22, Fig. 1, preferably made of gold or silver and having a weight between one and one hundred grams, connected by frameworks to opposite ends of a flexible steel link 17 and also to pivots formed by leaf springs 6, 7, and 8, 9 respectively, so that the tendency of masses 15, 22 to move about the pivots due to the normal force of gravity acts in opposite directions and with equal force on link 17 and is cancelled out, whereas the gradient of the vertical component of the gravitational field causes slight movement of the masses about the axes and may be measured or recorded by an element 25 connected in circuit with a capacitance bridge. The supporting blocks 2, 3 fixed to the wall of an evacuated chamber 1, pivotally support members 10, 12, by means of the horizontal and vertical leaf springs 6, 7, 8, 9. Attached to members 10, 12 are V-shaped frames 14, 19, connecting them to masses 15, 22, and V-shaped frames 16, 21, connecting them to opposite ends of link 17, single bars 18, 20, being provided between masses 15, 22, and opposite ends of link 17.

The duct wall of a MHD generator comprises a plurality of cup-shaped metallic modules 4 which are assembled on to insulating bars 12, with insulating material between the modules, where the bars are shaped to provide a coolant channel along the inside of the surface contacting the hot working fluid in adjacent modules. Each module is of square or rectangular form and has slots cut in two opposite side walls into which the depending parts of bars 12 fit. Cruciform spacer pieces of insulating material are held by the recesses in the walls of the modules and are secured by plastic resin or other material which ensures that the duct wall is gas-tight. The insulating bars 12 have blocks 13 which depend into the module to provide a small section flow path across the face of the module thereby providing a high coolant velocity across this surface, elsewhere the channel is of large section to minimize the pressure drop. The bars 12 are secured together to provide a fluid-tight assembly and parts of some bars can be removed to provide headers 14 for the coolant. The coolant flow may be either transverse to the bars (as shown) or along the length of the bars. The block 13 may be replaced by a similarly -shaped block of conducting material so that an electrical connection can be made to a selected module. Reference has been directed by the Comptroller to Specification 1,031,921.
