Title: Wagons' elevation and helicoidal descent merry-go-round
IPC: A63G1/46
Filed: 1964-09-28
Abstract: A merry-go-round comprises a vertical shaft 4 with a spiral groove 5 engaging projections from a sleeve 32 supporting passenger cars 10, which sleeve 32 is turned around said shaft by the passengers to lift the cars, and means in the form of a keyway 6 to guide said sleeve in a rectilineal path. The said sleeve projections comprise steel balls 40 which roll both in an internal groove 38 of the sleeve 32 and in the spiral groove 5 as the sleeve is rotated around the shaft 4 through worm gearing 31, 32 by passengers rotating cranks 13 while seated in the cars.

Title: Electrostatic image development apparatus
IPC: G03G15/09
Filed: 1969-08-06
Abstract: Means are provided for rapidly moving a magnetic brush 44 out of contact with a photoconductive drum 10 to prevent toner deposition on non-imaged portions of the drum. During developing, a magnet 59 comprising north and south poles 60, 61 separated by insulator 62 is positioned such that the main part 45 of its field is directed towards the drum. Fringe portions of the field enable a rotating, non-magnetic cylinder 51 surrounding the magnet to transport toner from a trough (30), Figs.2 and 5 (not shown) into main field 45 to form the brush 44. To stop developing a solenoid (SOL-1) Figs.2 and 4 (not shown) is energized to rotate magnet 59 through an angle such that field portion 45 is directed away from the drum. Preferably, as magnet shaft 65 rotates to stop developing, a collar 94 fixed thereto operates a pivoted blade 92 through linkage 95 to squash the brush 44. Simultaneously with these operations, an electro-magnetic clutch (71) Fig. 2 (not shown) disconnects the drive from cylinder 51. The trough (30) may be split into a portion containing cylinder 51 and a developer resevoir portion helical feed screws (42, 43) Figs.2 and 5 (not shown) extending through both portions to maintain a continuous flow of developer.

Patent ES-429719-A1 (ES)
Title: Recuperator for gas-fired radiant tube furnace
IPC: F27D17/00
Filed: 1974-09-02
Abstract: The recuperator unit is shown in association with a gas-fired furnace of the closed loop radiator type, (specifically U-shaped) as a substitute for the usual furnace exhaust stack or flue. It incorporates a set of vertically elongated internal, axially telescoped and radially spaced cylindrical wall or shell members, of which three optionally define a bidirectional passage for a continuous flow of blower-supplied air to be preheated prior to its combustion with a heating gas. The path of flow of the air upon entry from the blower line and in being preheated is initially upward through an annular, radially outer passage zone of the recuperator, thence downwardly upon reversal in a parallel annular flow through a radially inner passage or zone, thence radially outwardly to the hot air discharge piping of the unit and the furnace radiator. The radial spacing of the shell structure which defines the air flow path, and its heat transfer relation to a combusted air discharge flow from the radiator, is arrived at as the result of a careful combination of empirical and mathematical constraint considerations. The recuperator has a well-insulated external stack wall structure within which said radially spaced shells are disposed and an upright and vertically elongated ceramic core member is positioned within the innermost of the wall parts or shells above referred to, controlling an upward flow of gaseous products of combustion issuing from the furnace's radiator loop.
