Filed: 1972-05-26
Abstract: 1358353 Electric couplings AMP Inc 26 May 1972 [11 June 1971] 24913/72 Heading H2E [Also in Divisions H1 G2 G4 and F2] An interconnection assembly comprises a substrate having a plurality of apertures therethrough, a plurality of signal conductors having ends sealed in selected apertures and end faces proximate a face of the substrate. The signal conductors may be insulated wires, coaxial leads, waveguides, optical fibres or fluidic conduits. In one embodiment, Fig. 3, a fibre glass, ceramic or conductive substrate 2 is formed with apertures through which are inserted the ends of insulated wires 10, 12, 14, 16, 18. The holes are then substantially filled by painting, spraying, casting or moulding with an epoxy or like material which after curing is machined as by wheel 44 to leave the wires with exposed faces 26<SP>1</SP>, 28<SP>1</SP>, 30<SP>1</SP>, 32<SP>1</SP>, 341 to which electrical components are soldered or welded. When the substrate is conductive, it may be covered with an insulating layer, or regions round the holes may be etched back to prevent contact with the component except where ground connections are required, Fig. 8 (not shown). Instead of connecting the components directly to the exposed faces of the wires connection pads may be provided over the faces by electroless deposition followed by electrolytic thickening or etching out of an overall layer similarly provided. In the same electroless/ electrolytic process the wires may be coated to provide screening and convert them into coaxial leads. The same process would provide a reflective coating on optical conductors to reduce attenuation and cross-talk. The conductors may be temporarily held by encapsulant 98, Fig. 10, while the holes are filled, the encapsulant being removed with the aid of a release agent 102. If the encapsulant is metallic it may be left in place to provide screening and/or reflection. Several conductors may be formed from a single length by pushing loops through the apertures, Fig. 14 (not shown). The conductors may be inserted after the apertures are filled, Fig. 16 (not shown). Signal conductors in the form of hollow tubes for waveguides or optical or fluidic couplings may be provided by setting rubber or P.T.F.E. threads in a substrate as described above coating them with metal (with or without a plastics support coating) and finally pulling out the threads to leave the coating, Figs. 11-13 (not shown).

Abstract: 1,043,166. Gyratory crushers. KLOCKNERHUMBOLDT-DEUTZ A.G. June 26,1963 [June 29, 1962], No. 25409/63. Heading B2A. A gyratory crusher includes an eccentricallydriven breaking-head 4 connected to a stationary part of the crusher through a freewheel-coupling 28, so that the head is locked against entrainment by the crusher drive during idle running. As described, the freewheel-coupling 28 is connected to a stationary shaft and to the head 4 via a universal joint, comprising a torsion-bar 26 mounted for rocking but not rotation inside the inner hub 27 of the freewheel-coupling. This hub has an internal diameter sufficient to permit the torsion-bar 26 to follow the movement of the breaking-head 4. Arcuate teeth 24, 25, at each end of the torsion-bar, engage internal teeth 24<SP>1</SP> in the hub 27 and internal teeth 25<SP>1</SP> in a sleeve 37 which is secured coaxially in a spherical socket 14, in an adjustable piston 15. This is held against rotation but is axially displaceable in a bore of the stationary shaft. Adjustment of the piston varies the breaking gap and affords resilient protection from tramp metal entering the crusher. A spherical socket 13 which co-operates with socket 14, includes an opening 31 to permit rocking movement of the torsion-bar 26 during movement of the head 4. The outer ring 32 of the freewheel 28 is screwed to a neck-portion 36 of the breaking-head 4, and because of the action of the ratchet-wheel 30 in the free-wheel, the head can rotate only in one direction and is locked in the other direction when the machine is idling. When material to be crushed is fed between the head 4 and the bowl, a planetary-type backward movement is permitted by the ratchet wheel 30. When the wheel 30 rotates in the direction of the arrow 34, Fig. 3, each of a number of wedging rollers 29 is forced by helical springs 35 into the wedge angle between the wheel 30 and the outer raceway 32, so that there is immediate locking of the rotary movement of the head 4 in the direction of the arrow 34. Lubricating oil is supplied via a bore 23<SP>1</SP> in the piston 15 and a bore in the torsion bar 26, and flows back through the teeth 24, 24<SP>1</SP> into the breaking head.

Abstract: 1497544 Sensing light beam deviation BALFOUR BEATTY Ltd 5 Sept 1975 [7 June 1974] 25500/74 Heading G1A [ Also in Division E1] A method of steering a tunnelling-shield along a predetermined path comprises directing a laser beam along, or in a direction parallel to or at a fixed angle with, the axis of the predetermined path of the tunnelling shield; focusing the beam on to the imput end of a group of optical guides carried by the shield, the imput ends of the optical guides being arranged in an array in which the position of the input end of each optical guide relative to that of another is fixed, and displaying light transmitted through the optical guides on to a screen at which the output ends of the optical guides are so arranged as to facilitate ready determination of any correction required to be applied to the motion of the shield. The output ends of the optical guides at the screen may be arranged either to identify a particular propulsion ram or rams to be and/or not to be operated or to form a magnification of the array of the input ends. Roll of the shield about its axis is compensated for by an extensible periscope assembly 24 pivotally mounted on the inlet end of a lens assembly 23 for movement about the axis of the lens assembly. Off-line and off-level deviation of the tunnelling shield is detected by rotating a pair of wedge prisms 27 about the axis of the lens assembly so that the laser beam, which is parallel to the predetermined path but displaced from its correct axis, is interrupted at intervals by the rotating prisms and is deflected on to phototransistors 26 lying in three concentric circles on a diaphragm 25. A comparator circuit associated with the photo-transistors of each circle amplifies and compares the voltage imputs from the phototransistors on opposite sides of the diaphragm and the net output is fed to the associated indicating instrument. In another embodiment the diaphragm carries a plurality of optical guides in concentric circles which are connected through phototransistors to bridge circuits feeding associated indicating instruments.
