20140008075 | Downhole shut-in device for pressure variation testing in gas lift wells - The device is based on the principle of downhole shut-in of oil producing wells that do not flow to surface self-powered but require the injection of gas to lighten the fluid column and thus enable the well to produce. This downhole shut-in device comprises a check valve, an anchoring system, a seal system; an untethering system, a shock absorber and a sleeve for the protection of pressure and temperature memory probes. | 01-09-2014 |

20150306849 | REINFORCED STRETCH FILM AND ITS METHOD OF PRODUCTION - A method of producing a reinforced stretch film includes the steps of: providing an elongated base sheet of plastic stretch film having a longitudinal axis; forming a plurality of cord-like, elongated reinforcement members; positioning the plurality of reinforcement members to the base sheet where the reinforcement members extend along the longitudinal axis of the base sheet; positioning a plurality of plastic film strip overlay over each of the reinforcement members where the overlays being parallel and spaced from one another; and attaching the overlays to the reinforcement members and to the base sheet to fixedly sandwich the reinforcement members between the base sheet and the overlays. Whereby, the reinforcement members comprising parallel, elongated reinforcement strips defining elongated spaces therebetween. | 10-29-2015 |

20130189062 | HYDRAULIC PUMP CONTROL SYSTEM FOR LIFT GATE APPLICATIONS - The hydraulic pump control system enables the synchronization of two independently mounted hydraulic lifting cylinders in a lift gate environment. A directional valve is added to the hydraulic line path between the lift cylinders and their respective pumps and reservoir tank. By connecting two pumps to one motor, the synchronization of the pumps is enabled for power up operations of the lift, and through the additional application of the directional valves, the oil flow rate to the lift cylinders (e.g., during a power down operation) can be maintained as hydraulically identical, thus synchronizing the movement of each lift cylinder with respect to the other, even in the presence other outside conditions that would could otherwise cause a desynchronization of the lift cylinders. | 07-25-2013 |
