Patent ES-377079-A1 (ES)
Title: Sheet feeding apparatus
IPC: B65B27/02
Filed: 1970-02-23
Abstract: Courses of bricks are stacked with the interposition of a supporting sheet of veneer between a course with fork lift openings and the upper adjacent course, and of separating sheets of paper between the remaining pairs of adjacent courses. As illustrated, bricks from a conveyer 30 are transferred, one course at a time, by a carrying assembly 32 to an elevator at a stacking station 28. The elevator is lowered by one increment when photo-cells sense the presence of a new course of bricks. After the elevator has been lowered, a sheet is fed to the top of the stack from a vertically movable hopper assembly 40 comprising an upper hopper 44 which contains supporting sheets V, and a lower hopper 42 which contains separating sheets P. The assembly 40 is normally positioned to feed a separating sheet to the stack but may be moved under manual control to feed a supporting sheet. A supporting sheet is fed from the bottom of the hopper 44 by the engagement of abutments 256 on an endless chain with the bottom sheet in the hopper. The sheet is captured by rollers 64 and 66 and transferred by them to the top of the brick stack. During transfer, the sheet is supported by jets of air from compressed air pipes 222 and 224. When a separating sheet is to be fed to the stack, the assembly 40 is raised so that a sheet P 1 fed from the top of the hopper 42 via a discharge opening 80 is similarly transferred by the rollers 64 and 66. The sheet P 1 is contacted by rollers 106 on a feeding assembly 82. The rollers include one way clutches so that when the assembly 82 is moved to the right, the rollers are locked and move the sheet P 1 by frictional engagement. When the assembly 82 moves to the left, the rollers are free to rotate so that the sheet P 1 is undisturbed. After the feeding assembly 82 has been moved fully to the left, a spring (168), Fig. 7 (not shown), moves the assembly slightly to the right so that a bulge is created in the sheet P 1 . When the sheet P 1 is to be discharged, a suction cup 198 is lowered to engage the bulge and then raised to lift the sheet over a projection 92 on a stop 86. The sheet is then discharged by movement of the feeding assembly 82 to the right. The level of separating sheets in the hopper 42 is sensed by a feeler 240 in response to which a base plate 78 is raised to keep the top sheet in line with the discharge opening 80. The transfer of sheets from the hopper assembly to the stack is monitored by photo-cells which are able to distinguish between the supporting and separating sheets.

Title: System of digital measurement of the position of a first member slidably mounted upon a second rotating member
IPC: B23Q15/00
Filed: 1970-06-04
Abstract: A system of digital measurement of the position of a first member slidably mounted upon a second rotating member comprises a first stationary coupling coil and a second similar coupling coil mounted upon the second member coaxially with the rotary axis thereof and parallel to said first coil. Energy produced by a stationary high frequency power generator is fed to said first coil and transmitted inductively to the second coil from which it is derived and rectified, to provide d.c. power upon the rotating member for the energization of a pulse former producing digital position signals proportional to the movement of said first member and of a high-frequency signal generator modulated by said position signals. The output energy of the signal generator is transmitted inductively via said coils in a direction opposite to the transmitting direction of the power energy and the signal energy derived from the first coupling coil demodulated, to retrieve the original position signals for application to a translating device. In order to effect full decoupling between the power and signalling circuits, the power energy is transmitted in symmetrically balanced relation and the signal energy is transmitted in unbalanced relation to the center points of the coils as potential reference.

Patent ES-416844-A1 (ES)
Title: Stud welding apparatus
IPC: B23K9/20
Filed: 1973-07-12
Abstract: In the apparatus disclosed, a power contact interrupting the connection between a capacitor discharge device and one of two lines of different polarities that respectively carry current from the device to a stud member and a base member to be welded together, is closed regardless of which polarity of line is connected to which member, by energizing a relay with an alternating current source coupled to each line with a diode and connected to the base member through an operator-actuated trigger. The trigger forms part of the gun that holds the stud member relative to the base member for welding. When the operator actuates the trigger, the AC source attempts to pass one-half cycle of current to one line through one diode and then the other half to the other line through the other diode. The half-cycle passing through the line connected to the base member actuates the relay which closes the contacts. The device can then supply energy to the weld point between the members.
