Patent ES-331696-A1 (ES)
Title: Method of packaging ripening perishable plant foods to prolong storage life
IPC: B65B25/00
Filed: 1966-09-28
Abstract: Fruit (other than green bananas) of the type having, during ripening, a climacteric rise in respiration rate which in normal air at room temperature reaches a peak leading to the onset of senescence within seven days of the onset of the climacteric rise, is preserved by sealing a portable weight of the fruit, subsequently to onset of the climacteric but prior to onset of senescence, in imperforate sheet material (e.g. low density polyethylene film) of such permeability to oxygen and carbon dioxide in the thickness used and of such area relative to the weight of the packed fruit, and with such restricted initial content of air in the package, that continued respiration of the sealed-in fruit will initially establish and thereafter maintain within the package a controlled atmosphere of less than normal oxygen content and greater than normal carbon dioxide content and so reduce the rate of respiration and delay complete senescence of the fruit. The thickness of the sheet material used varies according to the particular fruit being preserved. Surplus air is removed from the packages before sealing by means of suction or by immersing the packages in an incompressible fluid such as water. Fruit exemplified are tomatoes, melons, cherries, blueberries, papayas, peaches, nectarines, plums, mangoes and ripe bananas.

Title: Production of coke
IPC: C01B3/30
Filed: 1967-04-19
Abstract: In a fluidized bed process for producing gases and coke from a hydrocarbon feed (see Division C5) carbon black produced is admixed or slurried with the feed and reintroduced into a low temperature zone of the process to form further coke. The carbon black is produced in a high temperature zone which is maintained at 2000 to 2400 F., and preferably does not exceed 2200 F. Coke produced varying in size from 95 to 180 microns is mixed with finely ground coke from the same source, blended with coal tar binder and prebaked to form an electrode.

Abstract: An artifical cocoonery is disclosed which includes a semi-circular assembly of radially disposed circumferentially aligned flexible rods, the surfaces of the rods being suitable for the attachment of cocoons by the silkworm. A plurality of the semicircular assemblies of rods is mounted so as to protrude from and be spaced along one side of an elongated shaft. The radial rods of one assembly are alternately oriented between the circumferential spaces of the rods of each adjacent assembly for hygienic sericulture. In one embodiment each semicircular assembly of radially disposed flexible rods is mounted from a hub or sleeve. A plurality of these hub-mounted assemblies is engaged or telescoped in abutting relationship upon a supporting shaft to form a cocoonery unit. In another embodiment, a machine for removing and harvesting the fully developed cocoons is disclosed having an elongated rotatable drum with means for attachine, one or more cocoonery units upon the surface of the drum with their longitudinal axes disposed radially from the axis of the drum and with the flexible rods, with the cocoons thereon, extending generally outwardly from the drum. The drum is mounted on a stand, having means to rotate the drum, and an elongated array of teeth in the form of a comb is pivotally and slidably mounted on an axis therefrom so that the extended ends of the teeth are substantially tangential to the drum surface and each tooth of the comb passes between the respective semicircular assemblies of the flexible rods of the cocoonery as the drum is rotated. An outermost tooth at each end of the comb passes adjacent to the outermost semicircular assembly of flexible rods. The spacing between each tooth of the comb and a rod as it sweeps thereby is sufficient to dislodge the cocoons. The comb is disposed at an angle to the periphery of the drum whereby a sloping surface is provided to convey the dislodged cocoons into a receptacle. The ends of the teeth of the comb may slidably engage the surface of the drum and maintain the sloping attitude of the comb about its longitudinal pivot.

Title: Articulated strap chute and guide means therefor
IPC: B65B13/30
Filed: 1974-10-25
Abstract: A normally retracted sectional articulated strap chute capable of being projected endwise and horizontally from a storage and guide channel through a pallet void for the purpose of directing a length of strapping endwise through the pallet void during the creation of a strap loop about an article disposed on the pallet. The storage channel, in the main, extends vertically for floor space conservation purposes but is provided with a short horizontal leg which is in register with the pallet void and from which the articulated strap chute is projected. The sectional strap chute, when considered as a whole, is flexible in one direction to enable it to follow the contour of the storage channel but is incapable of being flexed in the other direction so that such portions thereof as project from the storage channel are self supporting within the pallet void. Pneumatic means including a cable cylinder are employed for projecting and retracting the articulated strap chute.
