Patent ES-361749-A1 (ES)
Title: Recording and playback system incorporating a first character positioning system
IPC: G11B20/18
Filed: 1968-12-21
Abstract: The apparatus is similar to that disclosed in Specification 1,210,587 but is mainly concerned with the recording and playback of a reference character at the beginning of each track. Initially the card is driven at high speed in the reverse direction (23) until photo-cell 19 is covered, track return latch 67 is set followed by D1 which resets 67 and initiates forward drive (24). If a reference character has been previously recorded on the track selected, it is gated at 75 with D1 and 19 outputs and counter 77 gives an output when all bits of the reference character have been read, to reset D1 and set D2 or D6 depending on whether record or playback mode has been selected. In the record mode the card is driven in reverse and the reference character bits are applied to time out circuit 87 which causes an output from 89 when the reference character is correctly positioned between the read and write heads, D2 being reset and D3 set. If the reference character was found to be in error or missing completely, D4 may be set to initiate recording of a reference character, the card being driven in reverse at high speed until photo-cell 19 and gate 107 reset D4 and set D5, the latter initiating forward movement of the card and gating the reference character from a register 108. Bit counter 77 indicates when all the bits have been recorded to reset D5 and set D3 via gate 115. With a correctly recorded reference character, operation to record data characters is as described in Specification 1,210,587. If the playback mode has been selected, operation is as described above for the D1 cycle and D6 is reset when a data character has been read. If a change to record mode is required before the data characters are read, D2 is set by gate 117 to reposition the reference character between the read and record heads. Similarly if a change from record to playback mode is required before the first data character is recorded, gate 119 sets D1 and resets D3, D1 being reset and D6 set when the reference character has passed the read head. If a reference character is not sensed during the playback mode, the operator can proceed to read subsequent data characters or can choose to record a reference character by changing to the record mode (gate 103 sets 67 followed by D1

Patent ES-377670-A1 (ES)
Title: Improvements in bag filling machines
IPC: B65B1/32
Filed: 1970-03-18
Abstract: An automatic machine for filling bags with fluent solid material comprises a rotatable tank 1 for the material, a number (only one shown in drawings) of combined filling and weighing units spaced round the tank and each having a bag supporting spout 14 which communicates through a conduit 19 with a tank outlet 3, means for controlling the passage of the material through the conduit 19, and a bag discharge mechanism, the arrangement being such that in the absence of a bag on the spout, or camoperated bar 23 which operates both the means for controlling the passage of the conduit 19 and the bag discharge mechanism, is inoperative. Each combined filling and weighing unit includes a beam 8 suspended from an end of a lever 7 fulcrumed on a bracket 5 fixed to the tank 1 and counterbalanced by weights, not shown, at the other end. The lower end of the beam is connected through a link 9 having pivot pins 10 and 11, to the tank bottom 2. The beam 8 carries the spout 14 pivotally mounted on a pin 16. When a bag 18 is positioned on the spout, a claw 17 pivotally mounted on the beam 8 is moved to rest tightly on the bag. At a predetermined angular position of the rotating tank a cam portion of a rail 26 lifts a roller follower 25 to fully open the conduit 19 which is flexible, so that material starts flowing into the bag. A predetermined weight of the material in the bag, aided by an additional initial load 34 at a pin 33, the beam moves downwardly to close the conduit. At a further angular position of the tank, a cam portion of a rail 32 acts on a roller 31 to relieve the beam of the load 34 so that the beam floats up and a pawl mechanism 37 on the beam lifts the conduit-controlling rod 24 to partially open the conduit for a secondstage filling. When the required weight of material is in the bag, the beam 8 again moves down to close the conduit. At a further tank position the roller rises further to engage a lever 28 so that a bar 23 which operates the conduit-control rod 21 swings by gravity into an inoperative position and then the beam 8 rises to lift the claw 17 to release the filling spout which, under the action of the filled bag, pivots downwardly about the shaft 10 and the bag shoots off. The bag cannot be discharged unless the bar 23 is in an inoperative position i.e. unless the conduit is closed. Also a safety device 36 actuated by the bag does not allow the conduit to open unless the bag is present. The initial operation of mounting the bags may be manual or automatic. Mechanical vibrators &c. may be provided to shake the bags during filling and air may be blown through the bottom of the tank to fluidize the material therein.
