Title: Process for preparing resistive films
Inventor: WATKINS JOHN
IPC: H01B1/02
Filed: 1966-04-01
Abstract: <PICT:1112756/C6-C7/1> Even deposition of the components of a cermet film deposited from the vapour state on a substrate is obtained by successively vaporizing two or more portions of material containing the components, so that as the vapour pressure of, for example, the more volatile component of a two-component cermet, in the evaporation chamber drops off towards the conclusion of evaporation of the first portion (curve 1) preferential evaporation of the more volatile component from the second portion (curve 3) reinforces it.  Any number of portions may be successively vaporized, or material may be continuously fed to an evaporation station.  Movable masks are employed to ensure that deposition on the substrate takes place only while the concentrations at the vapours of the various components are such that deposition in the desired proportions takes place. Successive evaporation may be obtained by the use of different-sized sources in tantalum boats connected in series, so that when a current is passed the source in the smaller boat warms up first. Alternatively a single body of material may be contained in an elongated conductive boat of varying cross-section, or one whose electrical resistance is locally lowered by a metallic shunt or a fold in the metal of which it is composed.  Alternatively heating may be delayed by placing a heat-sink in contact with part of the boat. The cermet may contain silicon monoxide or magnesium fluoride and chromium, silver, copper, nickel, molybdenum, manganese or tungsten, or alloys of these, and be deposited on glass or ceramic substrates. Thin films deposited in this way are stated to be suitable for the manufacture of resistors.

Filed: 1927-06-02
Abstract: 272,229. Modo, M. June 3, 1926, [Convention date]. Catches yielding to pull; fastenings for sliding doors.-Fastenings for the doors of automobiles comprise a spring bolt a pivoted in a casing and having wedge-shaped projections e engaged by wedge-shaped lugs f on a slide for securing. The bolt a has a sinuous lip Y for engaging a corresponding recess Z in the staple m for preventing vertical movement of the door due to vibration. To release the door, the handle spindle h is turned, causing an arm r to rock a lever l to raise the wedges g out of engagement with the bolt-lugs e, by means of a lug i. If the handle is then pulled the bolt rocks on its pivots d round the curved face n of the staple and the door opens, enlargements w on the wedges g engaging the lugs e on the bolt to hold the slide in the inoperative position. On slamming the door, a pair of curved arms f of the bolt enter recesses q in the staple and cause the bolt to turn into engagement therewith. When the bolt has turned through a certain angle, the wedges g are released and move uy gravity or spring means into locking position between the lugs e and the casing. If the door is not completely closed when the automobile moves off, any jars in the opening direction are prevented by the wedges g, while each jar in the closing direction causes the wedges to move nearer and nearer to the completely secured position.

Title: A photoelectric device, for the inspection of cigarettes
IPC: A24C5/34
Filed: 1955-05-24
Abstract: 807,785. Photo-electric inspecting apparatus. CAPITANI, F. DE. May 24, 1955 [Dec. 30, 1954], No. 14920/55. Class 40 (3). A photoelectric device for inspecting cigarettes having two colours, e.g. having an ignition member of one colour and a striking member of another colour, both members being exposed through an opening in a cigarette paper wrapper of a third colour, comprises a source of illumination, photo-electric means receiving light reflected from the cigarettes and differently responsive to at least two different colours on the cigarettes, means for periodically generating electrical impulses, and means for ejecting faulty cigarettes controlled by means comparing said impulses with the response of the photo-electric means. Fig. 2 shows a tube 10 through which a cigarette rod passes, being cut to the correct lengths at H. The rod is provided at intervals with ignition members C, cut in two at H to provide each cigarette A with an ignition piece. The cross-section of Fig. 3 shows a light 28 illuminating the rod through a lens 26, prism 24, and mirror 20, the latter allowing light reflected from the cigarette rod to pass through it and fall on to a photo-cell 30. The output of the latter has a series of peaks, corresponding to the passage of each member C past the mirror 20. This output is compared with that of a generator synchronized with the speed of the rod, and generating peak impulses corresponding to those produced by the photo-cell when the cigarettes are correctly made, so that the output of a comparison device is zero. Imperfections in the cigarettes which involve the colour, e.g. incorrect positioning of member C, torn paper exposing tobacco, or incorrect positioning of a coloured Trade Mark, cause discrepancies between the photo-cell output and the generator output, these being detected by the comparison device and caused to operate a solenoid 16, Fig. 2, which moves tube 10 to deliver into a container P<SP>1</SP> instead of a container P, thus rejecting faulty cigarettes. Specifications 746,435 and 758,858, [both in Group VI], are referred to.
