Abstract: Sister hook type tool assemblies comprise mating arms having C shape lower ends grip portions that terminate in jaws. The arms preferably are held between two spaced apart housings. The arms, and housings when present, are held together by a fastener at the upper end of the assembly. The arms pivot relative to one another and to the mated housings. Each housing has a pair of forks at one end which define a U shape opening. An object received in the opening is retained when the jaw ends arms overlappingly close the fork opening, due to action of spring. The V shape lower end contour of the mated arms and inclined surfaces of the fork tips cause a rigid object to open the jaws when the tool is thrusted at the object. The jaws then close under spring force, capturing the object. Optional locking means are used to keep the jaws from unintentionally opening.

Abstract: Methods and devices for monitoring and/or controlling delivery of a fluid to a patient monitor a level of the fluid and generate an alarm and/or block flow of the fluid through a flexible delivery tube to the patient in response to detecting that the fluid level has dropped below a predetermined level. A device for monitoring and/or controlling delivery of the fluid to a patient is removeably mountable to a fluid delivery assembly having the delivery tube. When the device is configured to control delivery of the fluid, the device automatically reconfigures from a first configuration in which fluid is allowed to flow through the delivery tube to a second configuration in which the delivery tube is in a deformed state via the device to block flow of fluid through the delivery tube upon the device detecting that the fluid level is below the predetermined level.

Abstract: The described embodiments provide a subsea connector that is a quickly deployable and reusable. The subsea connector comprises a male and a female assembly that can be connected and disconnected. The male assembly includes a shaft, a sleeve that surrounds the shaft, and bars that are connected to the shaft and are configured to rotate about one axis. The female assembly includes a receptacle into which the male assembly can fit. Once the male assembly is inserted into the female assembly, the bars can rotate into such a position that the male and female assemblies are connected together. The bars can also be rotated such that the male and female assemblies can be disconnected.

Abstract: Apparatus adapted for adjusting the position of articles held together by tensioned fasteners such as bolts having a head, a threaded shaft and a nut into which the shaft is threaded includes first and second washer members that are receivable in a stacked array on the bolt shaft between the bolt head and an adjacent surface of one of the articles. Each of the washer members has a diametrically extending semi-cylindrical groove in the surface thereof which faces the other washer member. A cam lever has opposed cam pins of arcuate non-circular cross-section receivable between the washer members within the grooves. Movement of the cam lever to first or second positions thereof will cam the washer members away from or towards each other respectively, thereby applying tension to or releasing tension from the bolt so as to clamp the articles together or release them for movement relative to each other.
