Patent ES-343362-A1 (ES)
Title: Work guide in rotary cup feed sewing machines
IPC: D05B1/20
Filed: 1967-07-22
Abstract: A cup feed sewing machine in which the feed cups rotate about vertical axes comprises an uncurler guide having opposed work-clamping members pivoted to a pivoted arm and having extensions spring biased to engage said members with the arm, 'said extensions being located, when the arm is in an operative position adjacent the feed cups, adjacent a pair of converging surfaces, whereby, when the arm is swung away from the cups to an inoperative position, the extensions engage said surfaces to separate said members from the arm. The uncurler guide comprises an arm 65 pivoted on a shaft 66 journalled in a bracket 80. A pair of clamping members 70, 71, positioned one on each side of a blade 69 extending downwards from arm 65, are pivoted at 72 to arm 65 and have upward extensions 73, 74 biased apart by a spring 75 to engage members 70, 71 with blade 69. A spring 81 biases arm 65 clockwise to an operative position in which members 70, 71 are located adjacent the feed cups (36), 40, when the extensions 73, 74 are located adjacent converging surfaces 88 on a bracket 86. Arm 65 is rigid with a disc 76 which is journalled on shaft 66 and is formed with a notch 77 engaged by a spring- biased pawl 78, pivoted at 79 to bracket 80, when arm 65 is in the operative position. Shaft 66 is rigid at one end with an arm 67, and at the other end with a cam disc 68. Arm 67 is connected by a chain 82 and cable 83 to a pivoted arm (49) which is also connected by one linkage to feed cup 40, and by another linkage to the armature of a solenoid (94). When the latter is energised to lower arm (49), feed cup 40 is separated from. feed cup (36) and arm 67 is swung counter-clockwise, whereby a cam surface 90 on disc 68 raises pawl 78, and an abutment surface 91 on disc 68 engages a pin 92 on disc 76 to rotate the latter till pawl 78 is located on a peripheral surface 93 of disc 76. Extensions 73, 74 also engage the surfaces 86 and are thereby moved towards each other to separate the members 70, 71 from blade 69. The upper edges of a work piece are then positioned between blade 69 and the respective members 70, 71, the height of said edges being determined by their abutment with a pin 64' carried by blade 69, and said edges are also introduced between the feed cups (36), 40. Solenoid (94) is then de-energised, whereby cup 40 returns into abutment with cup (36), members 70, 71 return into abutment with blade 69, and arm 65 returns to its operative position, pawl 78 re-engaging notch 77. When pawl 78 is engaging surface 93, arm 67 may be turned manually counter-clockwise to engage pawl 78 with a notch 77' in disc 68. If arm 67 is turned further counter-clockwise, a cam surface 97 on disc 68 raises pawl 78 from notch 77', and further turning of arm 67 serves to position pawl 78 on a surface 98 on disc 68 to locate the members 70, 71 in a fully raised position. Brackets 80 and 86 are connected by a member 86' to a vertical rod 105 which may be raised by a lever 103 and link 99, against the bias of a spring 109, to vary the height of the edges of a workpiece.
Patent ES-346946-A1 (ES)
Title: Electroformed Metallic Structures.
IPC: C25D1/00
Filed: 1967-11-09
Abstract: A three -dimensional openwork material is formed by a series of tubes of electro-deposited metal running in random directions and joined together by electro-deposited metal, intercommunicating cellular spaces being formed between the tubes. Typically the material is produced by electro-deposition of metal on to the strands of a synthetic plastics open-cell foam material which has been rendered conductive. The plastics material may be a reticulated poly - urethane foam and may be rigidified by coating it with phenol-formaldehyde resin and made conductive by sprinkling conductive powder e.g. graphite or metal such as copper or copper bronze over the resin while it is still tacky. The foam material may be rendered conductive by chemical deposition of metal e.g. by reducing ammoniacal silver nitrate in situ with hydrazine hydrate or by sensitizing with stannous chloride, activating with palladium chloride and then effecting electroless deposition of silver, copper or nickel. Electro-deposition may be effected by pumping electrolyte, e.g. an acid solution of copper sulphate containing potash alum, through a tube 1 of insulating material in which a disc of foamed material 7 is located with a cathode connection being made to a silver face 10 of the disc and spaced from a grid anode 9. A subsequent electroplating of nickel may be applied. The plated plastic may be fired to remove the foam from the interior of the tubes leaving only a small ash residue.

Patent ES-366991-A1 (ES)
Title: Process for working-up crude liquid vinyl acetate
IPC: C07C69/15
Filed: 1969-05-09
Abstract: In a process for the purification of crude vinyl acetate containing acetic acid, water and ethyl acetate by azeotropic distillation of the vinyl acetate and water as the head product, and phase separation of the condensate, the vinyl acetate of this condensate is partly recycled to the azeotropic distillation column in a quantity such that the sump product contains 0À5 to 6% of water and acetic acid is obtained as the sump product. In a continuous process the tail acetic acid may be recycled through an evaporator to a reaction vessel in which vinyl acetate is prepared by reacting ethylene, acetic acid, molecular oxygen in the gaseous phase over a noble metal catalyst. A reflux ratio, based on the vinyl acetate of 3 to 8 is preferred. A second azeotropic distillation stage may be used to remove final water and acetaldehyde, and polymer impurities, and acetic acid traces are removed by a final distillation. In a modification an intermediate side stream may be withdrawn from the azeotropic distillation column and combined with the sump product to pass to an evaporator before recycling to the vinyl acetate production stage. This ethyl acetate rich liquid side stream may be taken from the distillation column, e.g. between the 8th and 16th plate of a 60 plate column.

Patent ES-368840-A1 (ES)
Title: Resilient railway vehicle truck supension
IPC: B61F5/16
Filed: 1969-06-26
Abstract: In mounting a car body on the bolster of a railway bogie, wherein a centre post 43, rigid with the underframe U, preferably has resilient pad connecting devices 49, allowing lost pivotal and transverse motion between the post and the bolster, but transmitting longitudinal motion, substantially without play, therebetween, additional transverse stiffness is provided in lateral springs, arranged between the underframe and the bolster, by making parts of the springs non-yieldable to transverse body movement. The lateral springs may be wholly pneumatic (Fig. 5, not shown) or partly pneumatic and partly constructed of a sandwich of elastomeric pads 37 and metal plates 39. Parts 37, 39 are made non-yieldable transversely by bridging them with inextensible links 57. Pneumatic parts 31, 33, 35, which are connected to a source of compressed air, are transversely yieldable, but are restrained against yielding longitudinally by links 36. Thus longitudinal yielding due to relative swivelling between the bolster and car body results in the parts 37 and 39, alone, being strained in shear. Links (77, Fig. 5, not shown) bridge convolutions (70, 71) of triple convolution flexible-wall pneumatic springs, to achieve the same effect. Reference has been directed by the Comptroller to Specifications 863,869 and 1,097,482.

Patent ES-387829-A1 (ES)
Title: Container unloading and transfering apparatus
IPC: A23L3/00
Filed: 1971-01-30
Abstract: The apparatus disclosed is particularly, but not exclusively, applicable for removing hot filled tins from a sterilizing basket where they are arranged in multiple layers or tiers on a vertically-movable bottom panel by raising the bottom panel in increments such that the cans of each layer in turn are pushed against a magnetic head and the basket then lowered sufficiently to leave the uppermost layer of cans suspended from the magnetic head. Said head then moves the layer of cans as a group laterally and drops them onto an endless conveyor, each layer in the basket being successively removed in this way. The conveyor carries the cans between parallel divider strips that arrange them in a plurality of lanes. Gate means are provided for simultaneously discharging the lead can in each lane onto a cross conveyor at the discharge end of the first conveyor, and when a can from each lane is positioned on the cross conveyor, the row of cans is carried single file from the ends of the lanes for transfer to a transport conveyor that takes them to a labeling machine or other apparatus to which they are to be delivered in single file. As each row of cans is carried away from the discharge end of the first conveyor, the magnet head will repeat its cycle to deposit another layer of cans, the operation continuing until all of the layers in the basket have been thus unloaded.
