Abstract: 1,050,081. Rolling. DAVY & UNITED ENGINEERING CO. April 20, 1964 [April 9, 1963], No. 14048/63. Heading B3M. The roll supporting housings of a rolling mill stand are adjustably supported by eccentric members for vertical movement relative to a foundation supporting the stand. The stand may include a pair of horizontal work rolls arranged within U-shaped housings 12 to which are prestressed upper roll chocks. Extensions 14 of the housings 12 are normally clamped by bolts 40 to the foundation, but for adjustment of the eccentric members the bolts are loosened. Cams 22 pivoted at 18 to the extensions 14 react against shoes 28 loosely held to the housings and hence against the foundations 38. A turn-buckle 50 which is axially restrained at its centre by a lug 58 and pivoted at its ends to levers 26 causes simultaneous adjustment at both sides of the housing. Lateral movement of the stand can be made using a piston and cylinder arrangement which co-operates with a pin 64. A pair of cams is associated with each extension 14, and the cams may, if desired, cooperate with the undersides of the extensions. In place of the cams 22, hexagonal, eccentrically pivoted members 68 may be employed, Fig. 5 (not shown), a bolt 84 clamping the extension 14 to the foundation 86. Alternatively, vertically disposed cam ended nuts 88 and 90, Fig. 9 (not shown), may be used, rotation by a lever 104 of nut 90 relative to nut 88 causing vertical movement of the mill stand.

Abstract: 1,052,352. Automatic control of plasticity. TOPPS CHEWING GUM CO. Inc. May 4, 1965, No. 18829/65. Heading G3R. The plasticity of a heat-softened product is automatically maintained constant by causing a signal dependent on plasticity to control thermoelectric cooling and speed of travel of the product relative to the cooling device. As described, a rope of extruded thermoplastic material, such as chewing gum to be sized, sliced, and wrapped, is transported on a thermally conductive meshtype conveyer band which slides over an electrothermal pile and has another such pile spaced above it. The piles are composed of antimony and bismuth elements arranged in series, with their cold junctions in thermal contact with but electrically insulated from 'cold' plates adjacent to the conveyer so that the gum is cooled. The hot junctions are similarly associated with 'hot' plates, further from the conveyer, which are cooled by water or air which may first pass in contact with the cold plates. Variations in plasticity from a desired value are detected by a potentiometer operated according to the depth to which a roller sinks into the gum after cooling. These variations are automatically corrected by utilising the potentiometer output, after amplification, to operate a servomotor system controlling the D.C. supply to the piles and the speed of an electric motor driving both the extruder and the conveyer. Safety switches may be provided to shut down the machine in the event of jamming or failure of the water cooling. Use of four piles surrounding the gum is referred to. Use of electronic control instead of electromechanical control is referred to.

Abstract: 1,229,030. Cathode-ray storage tubes; PN diode arrays. WESTERN ELECTRIC CO. Inc. 17 Oct., 1968 [18 Oct., 1967], No. 49347/68. Headings H1D and H1K. In a cathode-ray storage tube the storage target is provided on the surface scanned by a reading beam with a semi-insulating layer of such thickness that a capacitance is introduced in series with the capacitance of each storage element, the capacitance introduced having such a value in comparison with the target capacitance that the storage elements are only recharged partially during each scan and it is therefore possible to obtain a multiple read out of the stored information. In a scan converter tube with a diode array target as described in Specification 1,222,445, in which reverse biased P-N junction diodes 21 are formed on a substrate 20 and overlain with a silicon dioxide insulating layer 22 and a semi-insulating charge drain layer 24, this latter layer is formed to introduce the additional capacitances of appropriate value in series with the diode junction capacitances. The layer 24 may be a granular mixture of silicon and silicon monoxide providing a capacitance value over the diode junctions of 10<SP>-15</SP> to 10<SP>-14</SP> Farads with a resistivity value of less than 10<SP>9</SP> ohm-cms. For junctions of 8 microns diameter the layer thickness is 0À5 to 1À5 microns. Generally suitable materials for the layer 24 are silicon, silicon monoxide, titanium dioxide, gallium arsenide or antimony trisulphide separately or in any combination and in granular or amorphous form. The target includes an impurity gradient region 29 adjacent the input surface to prevent recombination of the minority carriers as described in Specification 1,228,627, and the target structure is manufactured in the manner described in that Specification. The substrate 20 is a slice of monocrystalline N-type silicon, 0-5 to 15 mils thick; the silicon dioxide layer 22 is 0À01 to 1 micron thick, e.g. 0À1 micron; boron is diffused into the substrate 20 to form P-type diode regions 21; and phosphorous is diffused into the substrate at 900 C. for 20 minutes to form the impurity gradient region 29 and also to facilitate the making of a good ohmic contact at 25, e.g. by use of vacuum evaporated gold. The substrate 20 has a resistivity of 0À01 ohmcm. forming diodes with capacitances of 10<SP>-13</SP> Farads. As an alternative the substrate may be of P-type material and the diode regions of N-type material with the reading beam removing electrons by secondary emission rather than depositing electrons. Reference is also made to the application of the invention to the target of a vidicon camera tube comprising a continuous photoconductive layer.

Abstract: 1,264,662. Adjustable crank mechanism. UNIROYAL. 25 Feb., 1969 [16 April, 1968], No. 42935/71. Divided out of 1,264,661. Heading F2K. In a drive mechanism incorporating a crank member and a connecting rod, adjustment of the effective crank length may be carried out whilst keeping the sum of the effective crank length and effective connecting rod length constant. General arrangement, Fig. 1.-A roller guide assembly 5a is reciprocated to and fro along fixed guide rail 2a by means of arm 4a, pivoted at 3a to a fixed frame. The roller guide assembly provides one of the supports for a structure 37 which transfers strips of fabric between fixed table 113 and a number of alternative locations such as B, C. Movement of arm 4a is effected by a connecting rod 15a and crank mechanism 10a driven by reversible motor 11a, the vertical shaft 13a of a speed reducer 12a comprising the axis of the crank. Adjustment.-Vertical shaft 13a is keyed to block 71a, Fig. 6, from which project two horizontal guide rails 14a. Adjustment means 70a include a carriage (74a), Fig. 7 (not shown), which is slidable on the guide rails 14a between plates 72a, 72a<SP>1</SP> fixed thereto. The carriage (74a) supports pivot means 16a, Fig. 1, for the connecting rod 15a; rod 15a therefore pivots with respect to carriage (74a) while the latter oscillates together with crank means 10a about the shaft 13a. A screw member 75a mounted in plates 72a, 72a<SP>1</SP>, extends through an internally threaded bore of the carriage (74a); thus rotation of screw member 75a by drive motor M1a causes longitudinal movement of carriage (74a) and hence adjustment of the crank length, i.e. of the distance between the crank axis at 13a and the pivot 16a. Before effecting such adjustment, the end of rod 15a which is linked to arm 4a is unclamped in its housing 7a, and the arm 4a is positioned at the end of its stroke, i.e. in in the Fig. 1 position. Adjustment of the crank length causes the rod 15a to move longitudinally through housing 7a, and it is then clamped again; the connecting rod 15a and crank member 10a are kept aligned throughout the adjustment and the sum of the crank length and connecting rod length, i.e. the distance between shaft 13a and housing 7a is unchanged. Thus the distance travelled by roller guide assembly 5a on rail 2a during its reciprocation is adjusted.
