Abstract: A waler bracket for use with a concrete forming systems which incorporates a captive wedge for tightening the wale against the form panels to bring them into planar alignment. The wedge is held in it's open position by means of a notch in it's edge.

Abstract: A form corner clip and method for making and using the same. A form corner clip is formed having a first portion and a second portion. The first portion is a latch to attach to a projection on a first form panel and the second portion, which is immovably attached to the first portion, has a projection that can be engaged by a latch on the second form panel.

Abstract: A form system wall tie and method for making and using the same. A wall tie is formed having a longitudinal axis and structure that is longitudinally symmetric. A tie rod at one end of the wall tie is attached to struts that, in turn, are attached to an attachment member that is adapted to engage a threaded rod. If desired, one copy of the wall tie can be engaged with a threaded rod having an anchor that can be affixed to a framework against which it is desired to pour a concrete wall, or the like, and the framework adjusted to the desired position. Alternatively, two copies of the wall tie can be placed end to end along the longitudinal axis and joined by a threaded rod, allowing a freestanding framework to be adjusted to the desired position before it is filled with concrete. The tie rod can be formed into shapes that are compatible with existing concrete form systems.

Abstract: A sample cartridge block that includes a first plate, a second plate and a third plate. The third plate is thermally connected to the first plate and the second plate. In some embodiments, the block is capable of holding a relatively high density of sample cartridges. In certain embodiments, the block provides good sample temperature stability while the sample temperature is held constant or while the sample temperature is being changed. According to the invention, a sample block may include one material or more than one material. Preferably, a sample cartridge block has a relatively low thermal mass. In some embodiments, the first plate of a sample cartridge block may have a larger surface area than the surface area of the third plate. According to the present invention, the first plate of the sample cartridge block may be thermally connected to a temperature controller. In certain embodiments, a sample cartridge block may have a relatively large surface area in contact with a temperature controller.

Abstract: A sheet of material seals vessels for biochemical reactions which undergo thermal cycling, and comprises a multilayer composite sheet which is placed over the openings of one or more reaction vessels. The multilayer composite sheet material has at least two layers, one layer providing strength and integrity to the material and the second layer being relatively thick comprising a deformable substance with a tacky surface to contact and seal vessels for biochemical reactions.
