Title: Safety nut and method for making
IPC: F16B39/38
Filed: 1977-04-06
Abstract: A safety nut comprises an axial extension in which an elastic safety element is disposed. In one embodiment the element comprises a wire spring clip whose legs are tangent to a central thread of the nut so that a bolt threaded onto the nut flexes the legs and creates a reactive clamping force. In another embodiment the elastic element comprises a spring disk having a thread which is axially offset at only a portion relative to the nut thread. A bolt tends to axial distort the disk and thereby creates an axial reactive force which clamps the bolt. During manufacture, the disk is threaded simultaneously with the threading of the nut and is thereafter deformed at at least one location to create the axial offset relationship between the threads.

Patent ES-487294-A1 (ES)
Title: Data processing apparatus having opcode extension register
IPC: G06F9/318
Filed: 1979-12-27
Abstract: A Central Processing Unit (CPU) includes a hardware op-code extending register (OER) for storing a code for programmable selection of optional CPU features which modify processor operations defined by the op-code in each instruction. A control section in the CPU decodes both the op-code of a current instruction and the code in the OER, effectively combining the two to form an extended op-code capable of defining a larger set of processor operations than the op-code carried in each instruction. The code in the OER is changed only when the CPU executes an instruction for transferring a new code into OER. Thus the code in OER can remain stationary over many instruction cycles.

Title: Seesaw targets apparatus for pinball game
IPC: F41J/
Filed: 1980-03-21
Abstract: An alternate target configuration is disclosed for a pinball game apparatus or the like, where two adjacent targets are mounted within a frame on the underside of the apparatus playfield, each adapted to move through a playfield opening between an exposed position above the playfield and a hidden position below the playfield. A linkage including an elongated member medially pivoted to the frame in the fashion of a seesaw is connected at its opposite ends to the respective targets, preferably when one target is exposed and the other target is hidden. The linkage is effective to shift both targets simultaneously from one alternate target position to another alternate target position where the other target is exposed and the one target is hidden. A spring toggles the seesaw linkage resiliently to the extreme limit of travel in each alternate target position. A motor overrides the spring toggle through an alternately reversed ratchet type connection to shift the seesaw linkage and reverse the positions of the targets. The motor is activated responsive to the exposed target being hit by the ball, and appropriate scoring apparatus is then energized.

Title: Apparatus for pumping foaming liquids
IPC: F04D9/00
Filed: 1981-10-19
Abstract: An arrangement for pumping foaming or frothing liquids comprises a pump connected to a sump (3), and at least that part of the sump located nearest the pump casing (1) has the shape of a truncated cone (5) with the apex directed downwardly.

Patent ES-8302174-A1 (ES)
Title: Door-locking mechanisms for security enclosures
IPC: E05B35/10
Filed: 1981-11-26
Abstract: A locking mechanism for a vault door having a plurality of independently negatable locks, each one coupled through its bolt to a respective pivoted locking arm. In the locking condition the arms are pivoted to block withdrawal of bars carried by the main boltstraps. Each lock bolt is connected to its arm by a rotatable control member having a lobe and an eccentric peg which engages in a slot in the respective arm. To negate a lock its bolt is thrown and a lever turned to rotate the respective control member. This places the lobe next to the lock case and pivots the locking arm into its unblocking position. If the door is left open with the boltwork withdrawn and unlocked unauthorized negation of a lock cannot take place because there is insufficient space to rotate the respective control member without the latter abutting the lock case. If the door is left open with the boltwork thrown and locked unauthorized negation might occur if access is gained to the mechanism, but this will be immediately apparent when the bank staff come to close the door at the end of the day as this procedure first involves withdrawing the lock bolts and the bolt of the negated lock will be blocked by the proximity of the control member lobe to the lockcase.
