Patent ES-454463-A1 (ES)
Title: Wear protective liner assembly
IPC: B24C9/00
Filed: 1976-12-21
Abstract: A protective liner assembly is provided for the walls of a chamber subjected to wear, particularly a blast chamber, with the assembly being formed of a plurality of individual liner units arranged adjacent each other in a two-dimensional array, each of the liner units being formed of a quadrilateral plate member having a pair of raised flanges extending along two of its edges on one side thereof with another pair of raised flange members extending along the other two edges of the plate member on the opposite side thereof. When the liner units are placed adjacent each other in a two-dimension array to form the protective liner assembly, the flanges of a plate member will overlap the flanges of adjacent plate members thereby to provide a shielding effect for a chamber wall upon which the liner units are mounted by screws extending through the individual plate members.

Title: Method and apparatus for forming palletless packages
IPC: B65B9/087
Filed: 1977-03-01
Abstract: A method and apparatus for forming a palletless package having a plurality of layers of objects, the bottom layer of which is formed with cavities to receive the fork arms of a lift truck. A stack of the objects to be packaged is first formed in a palleting device by placing the objects in a plurality of layers each having the same base area. Then, an additional layer of objects is placed on top of the stack in such a way that at least two recessed cavities are formed on opposite sides of the additional layer. A first shrink-on foil bonnet is then pulled over the top of the completed stack in a bonnet pullover device and the stack is transported to a first shrinking furnace where the first bonnet is heat shrunk onto the stack. The stack is then transported to a turnover device where it is rotated 180 DEG so that the additional layer and the recessed cavities are repositioned to the bottom of the stack. The turned over stack is then transported to a second bonnet pullover device where a second shrink-on foil bonnet is pulled over the completed stack covering the end opposite the additional layer. The stack is then transported to an addtional shrinking furnace where the second bonnet is heat shrunk onto the completed stack and so that overlapping areas of the first and second shrink-on bonnets were welded together. Conveyor means are used for transporting the stack between the various operating devices.

Patent ES-467568-A1 (ES)
Title: Fail-safe monitor of d.c. voltage
IPC: G01R19/165
Filed: 1978-03-04
Abstract: In some circumstances it is important to maintain a d.c. potential within a specific range of a critical value. The circuit shown will provide a fail-safe signal if the potential deviates from the allowed range. Two zener diodes and two optically coupled isolators are used. If the d.c. potential remains within the critical range, an a.c. test signal back biases one optically coupled isolator and forward biases the other on the positive half cycle and on the negative half cycle back biases the other and forward biases the one. Thus the two optically coupled isolators conduct on alternate half cycles of the a.c. test signal. If the d.c. potential strays from the required range, the optically coupled isolators stop alternate conduction and a fail signal is given. If either zener diode should fail in a mode which alters its characteristics so that the circuit would fail to detect a voltage excursion outside the allowed range, a fail signal is given.
Patent ES-468351-A1 (ES)
Title: Bipolar protective switch
IPC: H01H73/52
Filed: 1978-03-30
Abstract: A bipolar protective switch has a two-piece housing. An electromagnet constitutes the actuating device made either in the form of a zero voltage actuator or an excess current actuator. The armature of the electromagnet drops in the event of a voltage failure or is attracted if an excess current appears, thus disconnecting the switch. The switch can be turned back on again only after the voltage returns or normal current returns by the actuating device. A rocker is disposed on the narrow upper surface between the two pieces of the housing as the actuating member. The electromagnet and connecting members are disposed on the underside of the housing, a portion of the electromagnet being located between the two pieces of the housing. A support of an insulating material, is disposed in the housing upon which support connecting members are disposed. Two fixed contact members located side by side and two movable contacts, as well as a lever which is common to the two movable contacts is swivelable, and is subject to the force of a spring, the lever being connected to the rocker by a yoke. The lever is lockably connected with one arm of a two-armed release lever disposed on the support, the other arm being effectively connected with a release rod of the electromagnet.

Patent ES-480841-A1 (ES)
Title: Quickly adjustable ratchet wrench
IPC: B25B13/14
Filed: 1979-05-23
Abstract: A quickly adjustable ratchet wrench is essentially a crescent wrench modified by eliminating the adjusting screw and substituting a locking member and a lever to engage and disengage the locking member with the rack on the movable wrench jaw. A tension spring lightly biases the movable jaw toward closed position. With the locking member disengaged from the rack the movable jaw may be manually opened, and when the movable jaw is released the light spring bias closes the jaws on a bolt head. When the wrench jaws are engaged with a bolt head, rotation of the lever arm against a rearward extension that replaces the wrench handle engages the locking member with the rack to turn the bolt, while rotation of the lever arm away from the extension disengages the locking member and permits the jaws to open against the light spring bias and slip over the angles of the bolt head thus eliminating the need to remove and replace the wrench on the bolt head.
