Title: Improvements in the construction of electric switches
IPC: H01H77/10
Filed: 1921-05-05
Abstract: 179,815. Bolton, R. A. R. May 5, 1921 Oil switches: arcrupturing devices; switches partly electromagnetic. - The contacts are so arranged that, in addition to the main opening movement, a secondary movement is given which assists the opening and is dependent upon the strength of the current to be interrupted. Auxiliary contacts may be employed, or the main contact may consist of two pivoted members. Figs. 1 and 2 show a construction particularly applicable to oil switches. In the closed position of the switch, Fig. 1, the member d bridges both the main contacts a and the auxiliary contacts e, which latter are pivoted at k to the conducting arms f. The currents flowing round the angles f, k, e tend to make the contacts e fly outwards, but this tendency is overcome by the attractive action of the parallel currents through the main contacts a. On moving the member d downwards, however, contact is broken at the main contacts a. All the current now flows to the auxiliary contacts a, which consequently fly apart. In Fig. 3 the invention is shown applied also to the bridging- member, the arms g of which fly further apart as soon as the pins h clear the main contacts a.

Title: Holographic analyser
IPC: G03H1/00
Filed: 1974-03-25
Abstract: 1460793 Holographic apparatus XEROX CORP 25 March 1974 13195/74 Heading G1A A succession of image planes of a reconstructed hologram 6 are analyzed by a photo-electric scanner 14, whose output is compared with reference data in order to control the operation of a recording station to make a record of image-planes satisfying certain criteria. The invention is particularly applicable to the analysis of a hologram of a suspension e.g. gas particles dispersed in a liquid or solid, liquid particles in a gas or solid, or solid particles in a gas, liquid or other solid, in particular: fog, silt in water, plankton, duct in air, air or gas in plastics moulding as in a liquid &c. A hologram of the suspension is taken by transmission therethrough of light from a high power e.g. ruby laser with a short exposure to freeze any motion. In readout, a continuous He-Ne gas laser 18 is directed by lens 10, to the hologram, which is moved along the optical axis. A semi-silvered mirror 12 directs separate images to the record station 14 e.g. a photo-copy machine and to the scanner 14 which may be an array of photo-cells which may be associated with optical fibres, a line of photo-cells which scan the image plane, a T.V. camera or similar scanning cathode ray tube. The scanner output is fed to a progammed comparator and if a particular image-plane contains e.g. a predetermined number, size, shape or distribution of particles &c., the photo-copier is triggered to take a copy, which is also marked with the hologram longitudinal position, by electrical, mechanical or optical (e.g. a light image) transmission techniques, so as to indicate the image-plane in relation to the holographic volume record. In an alternative arrangement, the hologram may be fixed and the optical arrangement adjusted to produce different sequential image-planes for scanning.

Title: Improvements in or relating to electrolytic condensers
IPC: C25D11/18
Filed: 1954-05-06
Abstract: The aluminium-foil electrode of an electrolytic capacitor is formed, i.e. subjected to an electrolytic process to produce an oxide film thereon, in one or more stages and is annealed after each stage of formation by heating in an oxygen-free atmosphere. In a specific example, aluminium of 99,99 per cent purity is first treated in 6 per cent sulphuric acid under 20 volts D.C. with the aluminium as anode for three minutes.  The foil is then cleaned and dried and heated to 450 DEG  C. for one hour in an atmosphere of nitrogen.  A final forming stage in a boric-acid electrolyte follows this and is itself followed by a repetition of the annealing step.  The annealing may alternatively take place in an atmosphere of hydrogen, carbon dioxide or argon.
