Title: Float glass surface modification process
IPC: C03C21/00
Filed: 1967-04-15
Abstract: A method of manufacturing flat glass comprising separately contacting the surfaces of the glass with bodies of molten electrically conductive material isolating the molten bodies from each other and passing a controlled electric current through the glass between the isolated bodies thereby modifying the surface constitution of the glass particularly so that metal enters the surface layer when molten metals are used. The molten electrically conductive material is confined on the upper surface of the glass by forming the margins of the glass ribbon as ridges thus laterally containing the molten pool. The forward and rearward movement of the molten pool is prevented by carbon barriers. In one embodiment the electric current is passed through the glass in a direction such that the molten pool acts as an anode and the top surface of the glass is modified. By reversing the electrode leads and including other metals in the bath, the bottom surface of the glass may be modified. In another embodiment both surfaces of the glass may be modified simultaneously by having two molten pools of electrically conducting material confined on the upper surface of the glass and separated by a distance such that the pools are electrically isolated from one another, passing electric current through the glass between the molten metal surface and the pools of molten metal in a direction such that one pool acts as an anode and the other as a cathode with respect to the molten metal surface, and an apparatus for use in such a process comprising a tank structure containing a bath of molten metal 10, means for delivering glass at a controlled rate to the bath and for advancing the glass along the bath as a layer of molten glass in ribbon form, thermal regulators 23 and 24 for controlling the viscosity of the glass so as to ensure that the glass is gradually cooled as it is advanced, means for maintaining a pool of molten material 39 on top of the glass and for preventing forward movement of the pool with the glass, electrodes arranged to dip into the pool of molten material and into the bath of molten metal, an electric current supply circuit connected to said electrodes, and edge shaping means 31 and 32 mounted relative to the tank side walls 7 for shaping the margins 36 of the ribbon of glass 37 so that the ribbon assumes a shallow trough-like formation, and means for maintaining the pool of molten material in said trough. The bath is preferably molten tin or a tin alloy but may be lead or bismuth or an alloy thereof. The electrically conducting molten pool may be molten tin, lead or bismuth, an alloy of any of these with other metals (many specified) or a molten salt. The lead and bismuth alloys may be used to give colouring additions to the surface.

Title: Coil handling apparatus
IPC: B65B27/06
Filed: 1967-06-16
Abstract: Apparatus for transporting coils, e.g. of metal rod, from a forming station to a compacting and binding station includes a mandrel raisable through a slotted floor to support the coil during formation and to transport the coil along the floor towards the binding machine, the mandrel then withdrawing beneath the floor to return to the coil forming station. In one arrangement, a pair of mandrels 56, 78 are vertically reciprocable on carriages 40, 70 respectively, the carriages moving on a track 36. The carriage 70 also carries a pusher 112 which may be elevated through the slot in the floor 14 by linkage and piston and cylinder means 114a, 114b, 115. The carriage 40 oscillates between a coil forming station A and an intermediate station B, and the carriage 70 between the station B and a binding station C. As the carriage 70 moves to station C, the pusher 112 moves the bound coil at the station to an intermediate position D. A retractable arm 120 on a carriage 117 draws this coil on to a conveyer at station E. Coil forming and binding.-Coils are initially formed on a plate 26 when the latter is in its advanced position 26a within an open, fronted guide 18. When the mandrel 56 rises within the guide, the plate withdraws allowing the coils to drop over the mandrel and continue to build up round it. The plate returns when the coil is complete and may include shear means to separate the coil from the supply. At station C two bands are applied at 180 degrees. The mandrel 78 remains within the coil during binding and includes side grooves to receive portions 104b of guide tracks 106 on elements 92, 94. These descend to embrace the coil after the latter has been compressed, having first pivoted from the dotted inoperative positions shown in Fig. 4. Compression is produced by plates 96a, 96b which descend on either side of the mandrel. The tracks have hinged portions 107 which close to complete the circuits when binding is carried out by known means (not detailed). Alternative arrangement.-In order that the coils should be formed to a greater extent on the mandrel 56, the latter may be duplicated, each such mandrel being mounted on a separate carriage on either side of the machine centre line, Figs. 11, 12 (not shown). These mandrels are capable of passing each other and while one is feeding forward a coil to station B, the other is returning to station A.

Title: Foundry squeeze mechanism
IPC: B22C15/12
Filed: 1969-09-15
Abstract: A device for compacting moulding sand comprises a squeeze head 20 having cavities 27 within which hydraulically extensible rods 43 having peen feet 67 are arranged, each of the rods 43 being surrounded in its cavity by a flexible cylindrical sleeve 30 providing an interference fit with the rod, said sleeve being expandable within the cavity by exerting hydraulic pressure on it so as to be releasable from said interference fit to permit axial displacement of the rod 43. The fluid is supplied to annular grooves 54 and an axial groove 55 on the inner surface of each cylinder 30 from a source 63. The rods 43 are then displaceable by fluid supplied from a source 51, the downward movement of the rods 43 being limited by snap rings 47. In use, the rods 43 and feet 67 are set at predetermined heights by means of gauge pins 80, Fig. 1, and are then locked in position by the cylinders 30. The whole squeeze head 20 is then moved downwards to compact the sand in a flask (75). An alternative method of setting the feet 67 at the required height involves applying to the unlocked rods an hydraulic pressure corresponding to the unlocked rods an hydraulic pressure corresponding to the final sand pressure required and lowering the head 20 slowly to compress the sand. The rods 43 are thus forced back to desired heights and are then locked in position.

Title: Frame synchronization system
IPC: H04J3/06
Filed: 1971-05-13
Abstract: Frame synchronization for a binary data signal having a multi-frame including N frames, each of the frames including M channels and a first sync signal, at least one of the channel signals including in each of the frames a different one of (N-1) subchannel signals and a second sync signal is accomplished by employing two sync signal detectors, one being responsive to the first sync signal and a first predetermined local timing signal therefor to provide a first control signal indicative of the phase relation between these two signals and the other being responsive to the second sync signal and a second predetermined local timing signal therefor to provide a second control signal indicative to the phase relation between these two signals. The two control signals are samples by two different sampling circuits. The outputs of the sampling circuits are applied to two different decision circuits whose outputs control the timing of two cascade connected digital counters and timing signal generators used to generate necessary timing signals including the two predetermined local timing signals. The first digital counter and generator is driven by a bit rate clock which is inhibited when the decision circuit associated therewith indicates an out-of-sync condition. The second digital counter and generator is driven by a frame rate clock from the first counter and generator which is inhibited when the decision circuit associated therewith indicates an out-of-sync condition. In one embodiment, the decision circuits are dual integrators each generating two signals to separately control the inhibiting when required. In another embodiment, the decision circuits are single integrators each producing one signal to control the inhibiting when required, the signal of the decision circuit associated with the second sync signal being connected in a cooperating manner with the signal of the decision circuit associated with the first sync signal to control the inhibiting of the bit rate clock.
