Patent ES-349676-A1 (ES)
Title: Mould closure device for a pressure moulding machine
IPC: B29C45/68
Filed: 1968-01-23
Abstract: In an injection transfer or compression moulding machine or a pressure die-casting machine (see Division B3), a die plate 14 is moved to a die plate 11 (fixed on the machine frame 10) by at least one hydraulic jack 30 secured to the frame 10 by way of a bearing support 22 adjustably secured by nuts 26 to fixed bearers 15 on which slide the die plate 14 and a crosshead 40 with a toggle mechanism 62 connected between them when the die parts are closed together by the jack 30, a wedge 88 is lowered (to stop reverse movement of the crosshead and die plate 14) adjacent an inclined' end face 87 of a bar 86 on the crosshead and then the toggle 62 is actuated by an hydraulic control jack 44 (connected to the crosshead by tie bars 42) to lock the die parts 12, 13 together. The locking force is determined by adjusting the length of the jack rod 53, 57 (of a piston 52) by a screw connection in an enlargement 56 of the rod. The plate 14 rests on an adjustable foot 18 on a slideway 20. The bearers 15 may be vertical. The control jack 44 has rollers 48 running on rails 49 extending from the bearing support 22. In the open position shown, the working piston 52 is maintained at the cylinder end by fluid pressure (from an inlet 82) between the piston and an abutment piston 75 through which the rod 53 freely passes and which has a wider end 76 whose face 78 is subject to the same fluid pressure so that the piston 75 is held against a shoulder 80. When the pressure is switched from the inlet 82 to an inlet 81, the piston 52 is moved to abut the small end of the abutment piston 75 and a head 61 on the rod extension 57 is moved away from the crosshead 40 so that outer arms 64, 72 of the toggle linkage are brought nearly to horizontal alignment, Fig. 2 (not shown). The die parts 12, 13 are then brought together by the hydraulic jack(s) 30 and the wedge 88 can be lowered by a jack 90 to prevent return movement of the die plate 14 because the crosshead 40 is moved by the enlargement 56 on the rod 53, 57. Then, when pressure is removed from the piston face 78, the working piston 52 can move further right (by pushing the abutment piston 75) so that the toggle links are actuated further to align the links 64, 72 horizontally, Fig. 3 (not shown), and thus the locking pressure is applied as determined by the adjusted combined length of rods 53 and 57. Moulding (or casting) then takes place. The weaker force of the jack(s) 30 is sufficient during cooling. The toggle linkage is then opened, the wedge 88 removed and the die plate 14 moved back by the jack(s) 30. An ejector 100 carried by the plate 14 has adjustable rods. (not shown) for abutting the bearing support 22 at the reversing movement to eject the moulding (or casting). The locking pressure may be accurately determined by a comparator indicating the tensile force in the bearers 15.
Patent ES-349885-A1 (ES)
Title: Data transmission apparatus
IPC: H04L25/48
Filed: 1968-01-29
Abstract: Digital data is transmitted in one or other of two modes, e.g. 8-bit code or 4-bit code, transmission in each mode being preceded by a control signal. The control signals consist of two parts, the first of which readies the receiver for control by the second. If the first part of a control signal is simulated by data at the transmitter input that part is repeated so that the receiver is switched from the state of readiness by the repeat. Transmitter.-Parallel-bit input data passes via gate 19 to buffer 16 which via gate 22 feeds register 14 connected to transmission channel 12. When transmission is to be changed from 8-bit code to 2 x 4-bit code (in which each 4-bit group represents a decimal number) a control signal consisting of two 8-bit parts DLE, STX is transmitted. Decoder 20 recognizes the 8-bit DLE and via gate 31 sets bi-stable 30 to 1. The following 8-bit character STX is then transmitted and decoder 20 sets bi-stable 38 to 1 via gate 36. This bi-stable indicates the mode of transmission (or reception). Bi-stable 30 is reset via inverter 46 and gates 47, 48. Subsequently 2 x 4-bit code is transmitted. If two 4-bit words identical to the 8-bit word DLE fortuitously occur, bi-stable 30 is again set to 1 and a pulse passes via gate 36 and inverter 28 to inhibit gate 22 so preventing read out of the word DLE from buffer 16. The pulse also passes via gate 34 to set bi-stable 23 to 1 and via gate 52 and inserts DLE in register 14 for transmission. When a DLE is transmitted a signal appears on line 25 which passes via gate 60 to register 14 which now transmits a second DLE. To revert to the original mode a pulse on line 40 from the input unit resets bi-stable 38 and a control signal DLE, ETX is passed to buffer 16 for transmission. The DLE does not cause repetition because bi-stable 38 is reset. Receiver.-Serial-bit data on line 10 passes via register 14 and gate 17 to buffer 16 which passes it to the output unit via gate 18. On reception of the control signal DLE, STX bi-stable 38 is set to 1 as indicated above. If subsequently a DLE is, received, decoder 20 sets bi-stable 30 via gate 31 and sets bi-stable 23 via gates 36, 56. Consequently gate 18 is inhibited and the DLE is not passed to the output unit. If the following word is ETX, indicating a change in mode, decoder 20 resets bi-stable 38 via gates 33, 44. If however the following word was another DLE a pulse on line 67 passes via gates 66, 48 to reset bi-stable 30, so enabling gate 18 which passes this DLE to the output unit.

Title: Card reader transporter
IPC: G06K7/06
Filed: 1969-12-05
Abstract: A card 60 is driven across a support 16 which is movable between a non-reading position and a reading position, and a stop 27 locates the card in the correct position for reading on the support and controls the card drive mechanism. A motor 3 rotates drive wheels 18, 19 when insertion of a card is detected by a switch 22 so that the card is driven up against the stop 27 to operate a switch 24 which causes a solenoid 4 to pivot a cam 12 and raise the support 16 towards a reading head 30. Raising of support 16 opens a switch 25 to de-energize motor 3 and causes stop 27 to be depressed below the card by an arm 36 spring 26 moving it to its rest position beneath the card. In response to data read from the card, a computer transmits an accept or reject command to lower the support and reenergize motor 3 in the forward or reverse direction. The apparatus may be used in a cash dispenser e.g. located in a street outside a bank.

Patent ES-377082-A1 (ES)
Title: Heat treatment of hot rolled steel wire rods
IPC: C21D9/573
Filed: 1970-03-03
Abstract: Process for heat treatment in line with a wire rod rolling mill, of a steel wire rod containing less than 0.15 per cent of carbon and which has been previously subjected after leaving a rolling mill to the cooling treatment of a known controlled cooling process and device. The wire rod is subjected to an isothermal holding at a temperature between 200 DEG C and 400 DEG C so that the intersticial atoms place in a supersaturated solution during the known controlled cooling gather together on sites other than dislocations which allows the phenomenon of anchoring of the dislocations to be avoided, this anchoring being partially responsible for the deterioration of the drawability for the fine drawing of such steel wire rods. This thus allows the direct drawing of the wire rod without subsequent heat treatment to a final very small diameter. The process thereby avoids decomposition of a thin layer of non-adhering wustite formed on the surface of the wire rod during the controlled cooling treatment into an adhering layer of a superior oxide difficult to remove before the drawing off the wire rod.
