Abstract: A clip for retaining a set of decorative lights under the eave of a house having vented vinyl soffit panels. The clip is made of a slender strip of a resilient material having a major cross-section dimension which is smaller than the size of the perforations in the soffit panels. The slender strip has a backward bend in a mid-region thereof, defining a first leg member and a second leg member. The first leg member extends from the backward bend in a generally straight alignment defining a supportive axis of the clip. The second leg member has a first segment extending from the backward bend alongside the first leg member and a second segment extending from the first segment and defining an open loop having an opening contiguous with the first segment. This opening has a breath which is smaller than a size of the loop. The first leg member is insertable entirely into one of the perforations of the soffit panel and is readily oriented with the supportive axis of the clip laying over the upper surface of the soffit panel. When a cord of a set of decorative lights is hung from the loop, a bending moment caused by the weight of the cord in the loop about the backward bend increases a surface pressure of the first leg member against the upper surface of the soffit panel and enhances the retention of the clip to the soffitpanel.

Abstract: The present process is directed to the efficient recovery of helium gas from gasstreams which contain about 25 percent by volume or more helium. The process comprises two stages of pressure swing adsorption, each stage being comprised of a plurality of interconnected adsorbent beds. In the first stage of pressure swingadsorption which is comprised of about five phases, the helium content of the gas stream is increased to 95 percent by volume or more. A secondary product gas stream from the first stage of pressure swing adsorption is fed to the second stage of pressure swing adsorption. The second stage of pressure swing adsorption increases the helium content of this primarily non-helium product gas to more than about 50 percent by volume. This gas now with a helium content of more than about 50 percent by volume is fed along with the gas stream as the input gas to the first stage of pressure swing adsorption.

Title: Circuit array and process for creating a data feedback channel from receiver to transmitter in a common frequency network
Inventor: ZUMKELLER MARKUS
IPC: H04W72/04
Filed: 1995-11-25
Abstract: The establishment of an interactive broadcasting network requires not only a transmission channel from transmitter to receiver but also a transmission channel from receiver to transmitter. A novel method of creating a data feedback channel from receiver to transmitter is implemented in a common frequency network and involves the use of a transmission procedure in conformity with the DAB standard.  Each receiver or user is assigned an identifier which is transmitted in the data feedback channel at specially reserved frequencies to request transmission capacity. A computer then allocates transmission capacity to the receiver. The signals received in the forward channel are evaluated using the synchronization symbols they contain in order to synchronize the transmitter component in the receiver. The novel process can be used in all common frequency networks which use data transmission in conformity with the DAB standard and ensures a particularly economical synchronization in the receiver.

Title: Microelectrophoresis chip for moving and separating nucleic acids and other charged molecules
Inventor: YAGER THOMAS D
IPC: G01N27/447
Filed: 1996-06-07
Abstract: A microelectrophoresis chip comprises a substrate in which there are formed one or more channels, one channel for each sample to be evaluated. The channels extend for the length of the chip, a distance of generally around 1 cm, and are about 1 to 10 µm wide and 1 to 10 µm in depth. The channels are filled with a homogeneous separation matrix which acts as an obstacle to the electrophoretic migration of the charged molecules. Microelectrodes disposed in the channels are used to induce an electric field within the homogeneous separation medium. When a voltage is applied across two or more of the microelectrodes, the charged molecules are induced to move and separate according to the electric field density, the type of solvent film, and the charge, shape and size of the charged molecule. The chip may further comprise detectors, such as light polarization detectors, fluorescence emission detectors, biosensors, electrochemical sensors or other microcomponents which may include sites for enzymatic or chemical manipulation of the moved or separated charged molecules.
