Abstract: 1405618 Continuous casting CORNING GLASS WORKS 9 Nov 1972 [9 Nov 1971] 51690/72 Heading B3F [Also in Divisions C1 and B5] To form a honeycomb structure from extrudable material such as molten glass, ceramic batches, plastics and molten metal, the material is forced through feed passageways 18 to a guidework of interconnected discharge slots 24 and the longitudinal flow through the slots is impeded to promote lateral flow so that the material spreads to fill all the slots before being discharged as a honeycomb structure. As shown, a die 10 comprises a body 12 with the passageways 18 and an outer collar 14, the body 12. As shown in Fig. 4, the passages 18 communicate with alternate interconnected slots but other arrangements are disclosed. Outer feed passages 20 may be provided leading to an orifice 34 which forms an outer shell for the honeycomb structure. The orifice 34 is formed by an insert 32 secured on collar 14 and having an angled inner face 36 co-operating with an angled face 38 on body 12 to restrict the flow of material to the orifice 34. The resistance to longitudinal flow is affected by the viscosity of the material and also by the depth of the slots. The guidework can have any desired pattern such as round, square, oblong, triangular or hexagonal and the outer shell may be similarly shaped. The die 10 may comprise a number of sheets machined, stacked and clamped, brazed or bonded together. The slots 24 may be tapered at least in part. The die may be machined from aluminium or cold rolled steel or made from glass-ceramics, tungsten carbide or alumina.

Abstract: 1375362 Supply container for liquid sprayers J W CHAFER Ltd 2 Nov 1971 [2 Nov 1970] 51921/70 Heading AID A supply container includes means for introducing a metered quantity of fertilizer or pesticide in concentrated form to metal tanks 1, 2 connected to a pump 13. When the tanks 1, 2 are to be filled, pipes 33, 7 are connected to sources of concentrate and diluent respectively. Concentrate and diluent are drawn, either simultaneously or successively, by pump 13 through ports 22, 24 of three-way valve 8 into pipe 12, and thence into pump 13. From pump 13 liquid passes through ports 27, 25 of three way valve 9, and then through flow divider 5, Fig. 4, in which diagonal plate 34 divides the flow of liquid into equal parts, which pass through pipes 3, 4 into tanks 1, 2 respectively, ensuring equal filling and concentration of fertilzer in each tank. When filling is completed pipes 33, 7 are disconnected and when spraying is to commence, ports 22, 25 on valves 8, 9 respectively are closed. Liquid is drawn from both tanks by pump 13 through ports 23, 24 of valve 8 and 27, 26 of valve 9 into pipe 11 which carries it to boom selector valve 15. This directs liquid through one or more of pipes 16, 17, 18 to their respective boom 19, 20, 21 where it is sprayed out of jets 29. The pressure of liquid in pipe 11 is measured on gauge 28, and may be controlled by the supply of oil to motor 14. During spraying liquid from pipe 11 passes to a series of agitator jets (not shown) in tanks 1, 2. When the supply container is used in conjunction with a placement attachment, pump 13 is not used during spraying. Liquid from tanks 1, 2 is sucked out by the attachment through a pipe connected to valve 32. The concentrated fertilizer can be metered so as to introduce the correct quantity into tanks 1, 2 by attaching a probe to the end of he connection 33 from pump 13 and inserting it into the container of fertilizer. The tanks 1, 2 mounted either side of the front of a tractor as in Fig. 2 (not shown) are shaped to have a portion extending downwardly behind the wheels giving a lower centre of gravity, and hence greater stability, and a larger capacity compared with tanks of conventional rectangular cross-section.

Abstract: 1,246,066. Camera exposure control. HATTORI TOKEITEN K. K. Oct. 23, 1969 [Oct. 24, 1968], No. 52045/69. Heading G2A. A camera has means for selecting manual or automatic exposure time control. When under automatic control, a brake slows shutter opening to allow a light detecting element sufficient time to become fully operational. When under manual control, the brake is disabled enabling briefer, manually selected exposure times. As shown, for manual control, a ring 12 is rotated to select an exposure time and a ring 24 is rotated to set the required aperture value of a diaphragm mechanism (not shown). For automatic control, ring 24 is rotated to set the diaphragm at its maximum value and the amount the shutter blades open determines the aperture value, which is thus also automatically controlled. Automatic control. Rings 12, 24 are rotated to align marks "A" with a fixed mark 21, thus connecting a contact 22 on ring 12 to a photo-cell Fig. 2 (not shown). On pressing release 7, a switch 25 is closed energizing an electromagnet 19 which holds blade ring 3 while ring 2, slowed by brake 15 to 18, is rotated by spring 8 to open the shutter. The movement of ring 2 opens contacts 26 allowing a capacitor (C) to charge through the photo-cell, and a multi-vibrator circuit deenergizes electromagnet 19 releasing ring 3 to close the blades. Manual control. Rings 12, 24 are rotated to desired values, ring 12 disconnecting the photocell, connecting an appropriate resistance (RX) in circuit, displacing brake 15 by engaging elements 12b, 15c and rotating lever 11 to increase the tension of drive springs 8, 9. Pressing release 7 effects shutter opening as above.
