Abstract: A form tie for joining the sidewalls of a polymeric concrete form comprises a pair of end trusses with an intermediate web truss. Each end truss comprises an interior vertical strut and a longer exterior strut with interior and exterior pairs of horizontal struts extending therebetween. Upper and lower rectangular trusses and an intermediate truss are formed within each truss and rigidified by diagonal struts extending between the ends of the exterior vertical strut and interior vertical strut. The exterior struts of each end truss are coplanar with the exterior sidewall surface with the interior strut of each end truss being coplanar with the interior sidewall surface. The coplanar relationship of the struts serve as a visual gauge that the form with tie has been properly manufactured and assures that the end trusses extend throughout the width of each sidewall. End ties having a height of one-half of the form sidewall are extended between the sidewalls at the ends of each form.

A liquid feed to the passage area is provided so that a component of rotation around the direction of the main stream is added to the liquid with reference to the direction of the main stream.

Abstract: An integrated distillation column having a partitioned stripping or absorption section is presented. The integrated stripping/distillation column comprises a single shell housing a refluxed absorption section and a reboiled stripping section. The stripping section is partitioned by a vertical wall into first and second separate portions having upper end in fluid communication the absorption section. The stripping portions include fluid isolated lower ends having separate reboilers. In the integrated absorption/distillation column, the absorption section is partitioned and separate reflux loops are provided for each portion of the absorption section. In such a manner, a two column distillation process can be combined into one for achieving space and equipment savings.

Abstract: A device for reducing deformation of a pipe or tunnel has a body portion having a surface for moving along and entirely inside an undeformed pipe. The surface tapers inwardly from a main body portion having a maximum transverse extent to a fore end. Attached to the fore end of the device is a towing eye for attachment to a towing cable so that the device may be moved through a pipe. Movement of the device through the pipe urges the deformed portion towards an undeformed configuration. In an embodiment of the device it draws a lining through the pipe so that simultaneous re-rounding of a pipe and lining is performed. In yet another embodiment a pre-liner is simultaneously deployed with the lining, the pre-liner being disposed in use between the pipe and the lining.

Abstract: A process is disclosed for transfer printing thermoplastic materials with thermal diffusion inks. An image is transferred in a heatable press from a paper substrate colored with thermal diffusion inks onto an intermittently moved, fiber-containing carrier material into which the thermal diffusion inks can at first be sublimated then diffused. This fiber-containing carrier material provided with thermal diffusion inks is then transported into the gap between the calender rollers, where it is continuously brought into contact with a thermoplastic melt at an increased temperature so that the thermal diffusion inks penetrate into the thermoplastic melt and at the same time a composite strip made of the fiber-containing carrier material and the thermoplastic melt is formed. The products obtained by this process are suitable for producing a decorative layer on parts of skis or snowboards and on composite materials made of fiber-reinforced plastics.

Abstract: A method, and associated apparatus, for providing a wireless communication station with a dynamically-assigned address which provides a temporary address to route data to the wireless communication station. A temporary address is assigned to the wireless communication station to permit data, such as packet data, to be communicated between the wireless communication station and a correspondent host. Once communication with the wireless communication station is terminated, the temporary address can be reassigned and reused pursuant to subsequent communications with another wireless communication station.

Abstract: A fuel injection system which includes an injection valve for a self-igniting internal combustion engine with direct fuel injection, in particular for liquefied gas fuels, and which is configured as a pintle-type nozzle opening against the force of at least one spring, has the opening force of its fuel needle directly provided by the magnetic force of a solenoid so as to create simplified rate shaping. The magnetic force increases quadratically with the needle lift vis-a-vis the force of the spring increasing linearly with the needle lift, resulting in an opening velocity of the needle increasing approximately quadratically, at least in certain regions, thus permitting small pintle lifts, and the needle has a maximum needle lift of smaller than 1 mm, i.e., preferably smaller than 0.5 mm.

Abstract: This invention is a side wheel attachment for removably attaching an auxiliary side wheel to a bicycle. The side wheel attachment comprises a single structural rod which is folded in the desired shape, i.e. forms a helical torsion spring. In natural unbiased condition, the first and second ends of the spring rod extend generally perpendicularly to one another. The first end of the spring is inversely U-shaped and tangentially engages by its web the rear axle of the bicycle where it can be fixed after adjusting its vertical position relative to the bicycle. The second end of the spring rod is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends can angularly move relative to one another due to the helical spring. Therefore, in use, both auxiliary side wheels (installed on one side and the other of the rear bicycle wheel) and the rear bicycle wheel loaded by a bicycle rider, always stay in contact with the ground so as to accomplish their respective tasks.
