Abstract: Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

Abstract: The traffic barrier was designed to give law-enforcement officers an effective traffic barrier which can be easily carried in the trunk of a car and quickly deployed across a roadway and just as quickly, removed from the roadway as the situation warrants. There is no need for assembly or mechanical procedure, the chain is simply stretched across the roadway at a right angle to the direction of traffic and pulled taut. The traffic barrier chain is designed so that no matter how the chain is placed on the road surface, half of the splines will be facing the direction of the traffic flow at an angle of 45 degrees. The other half will be facing the other direction. Deployment of the traffic barrier chain is a preferable option to using an expensive patrol car for a road block, or attempting to shoot out the tires or radiator of a vehicle. The traffic barrier chain would be a useful addition to the entries of security facilities where traditional gates are vulnerable to breech by ramming with a vehicle.

Abstract: A siphon is formed of a long transparent main siphon tube having a distal end for insertion in a tank from which fluid is to be siphoned and having a proximal end. A smaller diameter transparent connection tube fits tightly within the main siphon tube at a proximal end but slides freely from the main siphon tube. An evacuating pump has a nipple connected to the inlet end, and the nipple fits tightly within a proximal end of the connection tube. After the distal end of the main siphon tube is placed in a tank, one pulls once or more on the plunger of the pump while gripping the proximal end of the main siphon tube and thus holding the connection of the main siphon tube and the connection tube.
