Title: Apparatus for handling material
Inventor: LAWS WILLIAM ROBERT
IPC: B66C3/04
Filed: 1972-02-23
Abstract: 1387881 Grabs BRITISH IRON & STEEL RESEARCH ASSOCIATION 23 Feb 1973 [23 Feb 1972] 8379/72 Heading B8H [Also in Division H1] Apparatus for attachment to an electromagnetic grab, Fig. 1 (not shown), for handling non-magnetic material, comprises frame 6 into which, in use, the magnet block 3 of the grab is inserted, there being four plates 15 (only one of which is shown), depending from the frame 6 to each of which a material engaging arm 13 is pivotally attached at 14, each arm 13 being operatively connected to a core assembly 16 formed of annular ports 18, 19 of magnetic material such that when the magnet block 3 is energized the core assembly 16 is attracted towards it causing the arms 13 to rotate inwardly to a material holding position. The first part 18 of the core assembly 16 is mounted on a sleeve 20 which is slidable relative to a central pillar 17 of the apparatus, said sleeve 20 having a projection 24 engaging in a recess in an outer sleeve 21 to which the core part 19 is attached. When the block 3 is energized the core part 18 and sleeve 20 move towards it carrying the sleeve 21 and second core part 19 with them. This upward movement of the part 19 results in a partial extension of each of four rams 28 (only one shown), each of which is connected between an arm 22 on which the core part 19 is mounted and one of the plates 15, and fluid is displaced via a lead 32 from each ram 28 into an associated ram 29 connected to a respective arm 13 causing a partial extension of the ram 28 and thus an inward closing movement of the associated arm 13. After the core part 18 has moved upwardly to its maximum extent the core part 19 continues moving towards the block 3 thereby causing more fluid to pass from each ram 28 to one end of its associated ram 29 to complete the closing movement of the arms 13. Fluid is displaced from the other end of each ram 29 into a fluid reservoir during the closing movement of the arms 13, the reservoir effectively storing up energy. When the block 3 is de-energized the combined weight of the material held in the arms 13 and the core assembly 16 causes the arms 13 to open, the force produced by the fluid reservoir helping to overcome any residual magnetic force.

Title: Imaging and depth profile analysis apparatus for use with ion scattering spectrometer
IPC: G01N23/203
Filed: 1975-02-28
Abstract: 1506175 Television systems MINNESOTA MINING & MFG CO 28 Feb 1975 [1 March 1974 (2)] 8502/75 Heading H4F [Also in Division H1] In an arrangement for the surface analysis of a sample a beam of ions of known energy and mass is raster scanned over an area of the sample. Primary ions scattered from the sample and having a selected energy are detected and a corresponding signal is generated. In the arrangement illustrated in Fig. 1 the ion beam from ion generator 26 is deflected by potentials on x, y deflector electrodes 57, 114 to provide a raster scan of a sample carried by support 61. Support 61 may carry several samples selectively presentable to the beam. Instead of beam deflection the support may be moved in a raster movement. Ions scattered along a path perpendicular to the ion beam pass via energy analyser 45 to ion detector 70 to generate a corresponding electric signal. The brief pulses in this signal pass via pulse stretcher 136 to c.r.t. display unit 112, the raster scan of the display being controlled by signals from the generators providing the ion beam deflection potentials. The ion beam energy and the energy of the detected scattered ions are selected by adjustment of the voltages applied to the beam generator 26 and ion analyser 45. In another arrangement (Fig. 2, not shown), the signal from the ion detector 70 is passed to a pulse height analyser (142) which feeds an indicator (80). The analyser is enabled only during a part of each scan line to avoid response to the edge of the crater formed in the sample by sputtering. The enabling signal is generated by comparator circuitry (140) which receives the outputs of the ion beam deflection potential generators.
