Filed: 1975-04-03
Abstract: 1474845 Positioning apparatus SUMITOMO CHEMICAL CO Ltd and MIYAZAKI TEKKOSHO KK 3 April 1975 [5 April 1974] 13669/75 Heading B8B An apparatus for replacing a spent anode A with a fresh anode Ao in an electrolytic furnace for alumium whereby the fresh anode has to be spaced the same distance above the furnace aluminium B as the spent anode, comprises an anode clamping lifting device 6, 1 which is reciprocable between the furnace and an anode mounting table C, a level sensing and indicating device 9 on the lifting device being operative only when the lifting device is actually supporting an anode whereby the correct level for a fresh anode over the furnace can be indicated irrespective of its difference in height with the spent anode. The lifting device 6 comprises a hydraulic cylinder having a pair of opposed spring closed and pneumatically opened latches 1 secured to the piston rod 6a, and the cylinder 6 being supported from an overhead travelling crane 8 through an adjustable load switch 7. The latter is set to close when the load of an anode is added to the apparatus weight, whereby a pulse generator 12 is energized for supplying a signal to the level sensing and indicating device 9. The pulse generator is driven by a speed reducer 11 having an input from a sprocket 15 over which a chain 13 passes as the piston rod 6a moves, since the two ends of the chain are secured to the ends of a lifter tube 2 movable with the pisotn rod 6a. With the indicating device 9 set at zero as the lifting device takes the load of the spent anode A over the furnace, the anode is lifted and the crane moved into position over the table C, where the anode is lowered thereonto and the indicator reading is "I" as the anode is released. The lifting device is then raised unloaded, to grip the new anode A, the indication on the device 9 remaining static until the indicating system is again energized upon lifting the new anode. After moving the lifting device into position over the furnace, it is lowered until the zero indication is achieved, when the new anode will be at the correct height above the furnace. In another embodiment the chain and sprocket arrangement driving the pulse generator, is replaced by a rack and pinion.

Title: Method and apparatus for the pneumatic conveyance and packaging of dry divided solidmaterials
IPC: B65B1/16
Filed: 1960-04-19
Abstract: 940,506. Pneumatic conveyers; packaging machines. ST. REGIS PAPER CO. April 19, 1960 [May 1, 1959], No. 13704/60. Headings B8A and B8C. [Also in Division G1] The air supply to a fluidizing container 41, Fig. 2, for discharging bulk material into bag filling nozzle 16 is controlled during the filling operation to maintain the energy level of the material below a condition of turbulence and instability. Fluidizing air is supplied through valves 61, 64 which direct the flow through alternative preset adjustable flow passages 57, 59 to change the flow between two predetermined values during the charging and discharging periods of the operating cycle. The valve 61 controls the flow to the primary supply line 43 for fluidizing screen 44 at the base of the container 45 and the valve 64 controls the flow to a secondary air line 52 for a perforated tube inlet 51 arranged above the screen 44. The flow passages 57, 59 are adjustable according to the material used and in one example during charging of the container 41 from the supply hopper 49 through feeder 50 the passages 57 are set to large openings so that the hopper 41 may be brought up to full operating pressure in a minimum of time. During filling of a bag when the outlet valve 19 is opened, the valves 61, 64 automatically change to direct the flow through passages 59 which are set to restrict the flow to the minimum necessary for satisfactory fluidizing of the material. An automatic control system (Fig. 4, not shown) for the various valves including also a hopper vent valve 70 is arranged to move the valves to the required different positions during the operating cycle, which is started by push button and stopped by either push button or automatically by the bag weighing apparatus. The control system may automatically open and close the vent valve 70 just prior to a bag filling operation to obtain an explosive material loosening effect within the container. The vent valve 70 may further be opened before complete discharge in order to reduce the flow of material to a slow trickle for more accurate weighing purposes. Examples of the application of the apparatus to an open top container and to a closed top container having an automatically opened and closed valve for gravity charging are described. Packaging-machines.-The scale pan 96, Fig. 3, supporting the bag (not shown) is tilted by an hydraulic ram 101 which is sequentially operated during the filling cycle. During filling of a bag the pan 96 is jerked suddenly downwards to shake the bag and assist in its complete unfolding. This operation is performed before the bag is so heavy that a sudden dropping of material due to unfolding would otherwise cause premature movement of the weighing mechanism to a full load portion at which the delivery valve 17 automatically cut off. After filling and release of the bag clamp 20 the pan 96 is tilted slowly upwards to facilitate removal of the bag.

Title: A Seat Frame
IPC: B60N2/04
Filed: 1967-03-23
Abstract: 1,174,792. Adjustable seats. RECARO A.G. 23 March, 1967 [23 March, 1966], No. 13777/67. Heading A4J. In a vehicle seating arrangement, in which access to the rear seat 29 is gained on moving seat 2 to an exaggeratedly, forward position, the rearward return movement of the seat 2 is terminated by an automatic re-engagement of pin 16 of leg frame 6, with a notch 18, in a cross brace 14, at the previously selected inclination of leg frame 6. With the sleeve 22 in its lowered position, (Figs. 2-5, not shown) slots 17 and 23 coincide and provide an L-shaped path along the horizontal limb of which the pin 16 is free to ride, on raising the free end of brace 14, thus allowing the seat to move into its extreme forward position. The sleeve 22 is held, during this movement, by pin 24 engaging a groove 25 in brace 14. On raising the sleeve however, into the position shown in Fig. 6, pin 24 is freed and pin 16 enters a notch (23<SP>11</SP>) facing notch 23<SP>1</SP>. The sleeve 22 is thus retained on the pin 16, while movement of the seat causes the brace 14 to slide therethrough. When the seat reaches its selected position of adjustment, the sleeve 22 is released and springs 27 and 28 effect re-engagement of pin 16 in a notch 18 and of pin 24 in a groove 25. In a modified locking mechanism (Figs. 8-12, not shown) a cylindrical sleeve (122) slides along and around a brace (114) of round section. The sleeve has diametrically opposed L-shaped slots (123 and 130) which are functionally equivalent to the T-shaped slot 23, 23<SP>1</SP> (23<SP>11</SP>). The seat 2 may alternatively be mounted at the rear on a sliding pivot (12, Figs. 13-14, not shown) and the brace (14<SP>1</SP>) may have its fixed pivot (15) on the front leg frame (6<SP>1</SP>) and its movable pivot (16<SP>1</SP>) to the rear.
