Patent ES-344756-A1 (ES)
Title: Packaging machine
IPC: B65B19/34
Filed: 1967-09-05
Abstract: A machine for packaging elongated articles, e.g. cotton-wool tipped sticks, comprises groups of grippers on a rotary turret which each lift a batch from an infeed conveyer and deposit it in a box on an adjacent turntable, the arrangement being such that, as one group is depositing its load, so that group following it is picking up the next batch. Several batches may be deposited in each box. In one embodiment, each gripper head 22 comprises a vertically slidable carriage 24 to which is secured a block 43, Fig. 3. Comb-like elements 48 having teeth 50 depend beneath the block in which are rotatable vertical gripper rods 44 in a row between the two rows of teeth 50. The upper ends of the rods 44 are linked for uniform rotation to a bar 42, the bar being secured to a connector 38. The rods 44 are rotatable through 90 degrees from a position, Fig. 4, in which they pass between alternate cotton-wool sticks 52 to a position in which they grip the sticks by grooves 58 against the comb teeth 50 which occupy the remaining spaces between the sticks, Fig. 6. To release the sticks, the movements are reversed. An ejector 180, spring-biased downwards, engages the sticks to ensure their ejection when released. The connectors 38 of adjacent heads are joined by relatively stiff cables 30b, slidable in fixed coverings 30a to levers 32 having cam follower rollers 33, 34 on their ends. In operation, sticks are fed in by an intermittently movable conveyer 54 and a batch is raised clear of it by blades 82 on rotary members 70. A head descends so that the teeth and rods pass between the raised sticks. A plunger 96, Fig. 1, then presses a cam-piece 106 between adjacent followers 33, 34, shifting the connector 38 anti-clockwiae, as shown, to cause gripping of the sticks. The previously loaded head, now located over a turntable 11 on which the boxes 13 are carried and which descended at the same time as the head over conveyer, to place its load within a box, releases its load, the respective connector 38 being shifted clockwise by the cam-piece 106. Each box is located on the table 11 by wedgeshaped elements 176, having leaf springs (175), Fig. 10 (not shown), to one side, and pins 178. In an alternative embodiment, Figs. 7, 8 (not shown), simple suction grippers may be used. An arcuate manifold (180) blowing hot air into the loaded boxes to dry the contents may be arranged above the table, Figs. 11, 12 (not shown).

Title: Machine to stack bars
IPC: B65G57/18
Filed: 1968-02-01
Abstract: A machine for stacking bars 2, e.g. angle irons, comprises an input table means for translating a layer of bars on the input table to a series of support members 12 movable rectilinearly to a vertically movable stacking table 19 and an electromagnet 25 on an arm 26, pivotable about a horizontal axis and adapted to remove alternate layers of the bars from the supports 12 and turn them over and deposit them on the stacking table 19. The input table comprises oblique rollers 1. A layer of bars 2 is transferred from the input table to the support members 12 alternatively by pairs of arms 4 or 5 carried on a rotary parallel motion means 6, 7. Either the support members 12 move the layer directly to the stacking table 19 or alternatively the electromagnet 25 which comprises a number of elements, rotates and picks up the layer 2 and inverts it on to a layer previously deposited on the table 19. The arms 4, 5 have abutments 8, 9 which align the angle irons on the input table, and one abutment 9 is adjustably positioned so that the layers are nested on the stacking table. The support members 12 are reciprocated by a rack 13 and the angle irons are deposited on the stacking table on the return stroke of the support members 12 by pivoted weight biased abutments 22 on the frame of the machine. The stacking table consists of parallel supports between which the lift members 30 of a truck 29 can pass. As the stack builds the stacking table 19 is vertically displaced by a jack 21.

Title: Electric refrigerator with defrosting means
IPC: G05D23/24
Filed: 1968-02-13
Abstract: A refrigerator particularly of a domestic type has at least one main compartment and at least one freezing compartment and at least one common evaporator connected to a compressor. In one phase of operation a compressor motor 45 is controlled by a thermistor 27 in the main compartment and in a selectively alternative freezing phase the motor 45 is controlled by a thermistor 37 in the freezing compartment and the temperature in the main compartment is adjusted by a heater 44 controlled by thermistor 27. A defrosting phase is also incorporated which is terminated by the thermistor 37 switched to provide a different temperature range. In position a, b of a switch G thermistor 27 controls motor 45 through a transistor 28 and relay 31 to regulate the main compartment temperature. Periodically e.g. once per 24 hours a timer motor 50 momentarily closes a switch 49 energizing a winding 47 of a defrosting valve and a relay 51, which is held over contacts B which shunt contacts 49, contacts A energizing motor 45 causing hot gas to be passed through the evaporator. When the temperature rises to a point determined by thermistor 37, a relay 41 is energized opening contacts f, g which disconnects the defrosting valve and relay 51, and closing contacts e, f re-energizing motor 45 until the temperature falls so that relay 41 de energizes. In position a, c, of switch G the motor 45 is controlled by thermistor 37 switched to a lower temperature range through a transistor 48 and relay 41. As the main compartment temperature drops below the operating point of transistor 28, heater 44 is energized through contacts f, g of relay 31 to maintain this temperature. In an alternative arrangement Fig. 3 (not shown), a heater (52) replaces the defrosting valve and motor 45 is not run during the defrosting period.

Patent ES-409611-A1 (ES)
Title: Photonically partitioned continuous gas envelope and transiently energized pilot discharge areas used in address selection of display firing coordinates
IPC: H01J17/49
Filed: 1972-12-14
Abstract: Plural pilot cells in a gas panel envelope are energized selectively and transiently to effect partial control of firing coordinate selection. The pilot cells remain unenergized during normal sustaining periods and firing potentials are chosen to preclude sustaining discharge of pre-ignited unselected points so that pilot bias is produced exclusively by the pilot cell operations. The pilot cells and associated display coordinates receiving pilot bias therefrom are photonically isolated from each other by suitably spaced glass spacing rods. Since the pilot cells are only transiently energized less power is consumed and the pilot light emissions do not interfere with the apparently continuous light at the sustained display coordinates. Hence the pilot emissions need not be masked from view. Since the pilot lights have dual usage as a coordinate factor of firing selection other parameters of firing coordinate selection (i.e. voltages directly applied to the coordinates) and associated selection circuits may be simplified and reduced in size to effect cost and power economies.
Patent ES-419173-A1 (ES)
Title: Method of and device for the manufacturing of electrical conductors
IPC: D01H1/08
Filed: 1973-09-28
Abstract: A method of and device for manufacturing electrical conductors, in which individual metal wires are assembled to form a strand in a first process phase, the wire strand being subsequently twisted in a second, separate process phase. During this second phase, the strand is fed from a driven spool into a rotating container and is subjected to a first twist. Subsequently, with an unchanged direction of rotation, the direction of movement of the strand is reversed, and the strand is rewound onto the spool, the strand thus being subjected to a second twist. The device for performing this method comprises a drive for a spool, a rotating container with a wire guide, and a winding mechanism with a synchronizing unit.

Patent ES-438079-A1 (ES)
Title: Automatic positioning system and method
IPC: H01L21/30
Filed: 1975-05-30
Abstract: A first workpiece is automatically and precisely aligned to a second workpiece by superimposing and aligning an artificially, electronically generated reference pattern of zones to a video image of the first workpiece. Then, a video image of the second workpiece is superimposed on, and aligned to, the reference pattern. Embodiments are disclosed for automatically aligning a semiconductor chip to a compliant tape window and then to a substrate for bonding operations and for automatically aligning a semiconductor wafer to a photoresist mask. The pattern of reference zones is generated electronically by applying the horizontal and vertical sync pulses of a vidicon to appropriate logic circuitry to thus artificially produce electronic signals representative of a video image of the desired pattern of zones. To accomplish X, Y and theta positioning, detected video coincident with selected opposed zones is summed, compared, and equalized by moving the zones or the workpiece. To align the pattern of zones to the first workpiece, motors are used to adjust variable resistors in the logic circuitry to move the pattern. To align the second workpiece to the pattern of zones, motors are used to drive micromanipulators to move the workpiece.

Patent ES-453500-A1 (ES)
Title: Reference signal circuit
IPC: G05B9/02
Filed: 1976-11-19
Abstract: In a prime mover control system, control over the prime mover is dependent, in part, upon the validity of a reference signal to the control system. Circuitry is provided between a reference signal generator and the control system whereby under normal conditions the reference signal to the control system is the same as the output of the reference signal generator. However, if the reference signal generator output becomes invalid, then a stored reference signal may be substituted for the reference signal generator output by switching from a first signal channel to an alternate second signal channel, each channel selectably interconnecting the reference signal generator and the control system. The output of the second signal channel is periodically updated to follow, with a time lag, the reference signal generator output except when an invalid reference signal generator output is detected whereupon the update of the second signal channel is frozen at a last valid reference signal which is then input into the control system.
