81	MAGNETIC HOLDING BRAKE AND ACTUATOR WITH A MAGNETIC HOLDING BRAKE	EP12765994.4	2012-09-10	EP2893231A1	2015-07-15	LENZ, Norbert
A magnetic holding brake (1) having at least one turning brake member (4) allocatable to a rotatable part (2) of an actuator (3) and a fixed brake member (6) allocatable to a torque-proof part (5) of the actuator (3). The turning brake member (4) and the fixed brake member (6) each at least have one permanent magnet (7, 8) of different polarity. The permanent magnets are lying opposite to each other in a pre-defined relative position of the turning brake member (4) and the fixed brake member (6) under exertion of a braking or holding torque. In this manner, the possibility exists that a holding in the so-called “fail as is”-mode is more easily and reliably and at the same time cost-efficiently achievable without wear or further energy demand.

A head is sealingly disposed within the passageway between the inlet and relief outlet closing the fluid flow passageway between the inlet and relief outlet. An elongate buckling rod supports the head and is bucklable at a predetermined load thereby permitting sliding of the head from between the inlet and a relief outlet and opening the fluid flow passageway. A lateral support projection is extendable within the housing to buttress the buckling rod along the longitudinal length of the buckling rod thereby increasing the load at which the buckling rod is collapsible.
99	Hydraseal frac valve	US13869744	2013-04-24	US09850740B2	2017-12-26	Don Atencio
A valve seal assembly can be energized by external pressure, such as by hydraulic pressure introduced via injection ports, so as to press the seal assembly against a gate with enough force to block paths where sand and chemicals would otherwise enter the valve body cavity or void. The external pressure makes the parts of the seal assembly move like a piston, forcing the seat of the seal assembly to press against the gate, eliminating the machined tolerances or gaps required for the gate to be opened or closed. A separate valve seal assembly can be provided for each face of the gate, and both assemblies can be activated when the gate is in an open position (fluid is flowing through the valve), and an upstream valve seal assembly can be activated alone when the gate is in a closed position.
100	Hydrocarbon pipeline pressure safety relief bypass system	US14956294	2015-12-01	US09841114B1	2017-12-12	Alfredo Lozano Aguilar
A method, system, and apparatus are provided for a safety relief bypass system for an oil pumping pipeline that provides pressure relief to the pipeline in order to prevent and reduce pipeline rupture. More specifically, the bypass system can include one or more rupture discs having a specific burst pressure that allows fluids under pressure to bypass through alternative pipeline thereby preventing damage to other piping components.
