IPC: H01S3/08
Filed: 1994-04-21
Granted: 2006-01-24
Abstract: This invention relates to a diode pumped slab laser in the form of a slab (1) where two opposite faces (2, 3) are adapted to receive pumping radiation with the faces being cut at the Brewsters angle at one sad (6, 7) to provide entrance/exit faces for the lasing radiation. The laser radiation beam follows a zig-zag path in the slab (1) and is contained within the slab by total internal resection. The laser slab (1) is contained within an optical cavity which results in the laser beam completing a double zig-zag beam path. The design results in good pump/mode matching, mitigates thermally induced birefringence problems, overcomes amplified spontaneous emission problems, requires no coatings or curved surfaces, and is easy and relatively inexpensive to make. The slab (1) can be used within both Quasi-CW and CW modes.

Abstract: A thermal printer (10) prints linerless labels (13) in such a way that printer components will not stick to the adhesive face of linerless labels.  Substantially stationary printer components, such as a label guide (15), transport plate (16), front panel, and stripper blade (42), preferably have the adhesive face engaging surfaces (50) thereof plasma coated so that adhesive will not stick to them.  An optional cutter (60) provided downstream of the stripper blade also has plasma coated surfaces (62, 67).  A driven print roller (17) has a surface thereof coated with or covered by a high release silicone, which will not stick to the adhesive, but has high friction characteristics to facilitate drive of the labels.  In a direct thermal printer, a plasma coated tear-off surface (90) is downstream of the driven print roller, and stripper belts (91), a second roller with O-rings (93), and the like are provded to prevent the labels from wrapping around the driven print roller.  One or more sensors (85) may also be provided for controlling drive of the print roller in response to the position of registration marks on the linerless labels.

Abstract: A method and apparatus are provided for communicating VBI user information for digital television. A syntax is provided which allows the transport of closed captions, non-realtime video, sampled video and AMOL. Non-realtime video can be used to transport various types of data, such as a vertical interval test signal (VITS) through the system at full resolution. The provision in the syntax of a count for each type of VBI user information enables the adjustment of a digital television data stream to accommodate variable amounts and types of such information without space being reserved in advance. The provision of a priority number in the syntax enables decoders to discard VBI user information priorities which are not supported by the particular decoder.

Abstract: This invention relates to a process for converting ethylene to a mixture of 1-olefins by (a) feeding ethylene through an oligomeriza tion catalyst bed to form an oligomer predominating in C2-C6 olefins and (b) fe eding the oligomer, optionally admixed with fresh ethyl ene, containing at least 50 % by volume ethylene, through a metathesis catalyst b ed to form a product predominating in C2-C6 1-olefins. Steps (a) and (b) can be carried out sequentially and in a single reactor under th e same conditions of reaction temperature and pressure. This mitigates the perceived disadvantages of low activity and low conversions of relatively inexpensive oligomerization catalysts and f orms oligomer having the desired distribution of 1-olefin components for use as c omonomer in a polyolefin process.

Abstract: The present invention relates to a process for determining harmonic oscillations of a fundamental component of an electrical signal, wherein the signal is sampled with a sampling frequency corresponding to a multiple of the fundamental component's frequency. The sampled values of the signal are subjected, after analog-to-digital conversion, to a discrete Fourier transformation to determine the harmonic oscillations. The sampling is performed with a non-integer multiple of the frequency of the fundamental component and the discrete Fourier transformation is performed while the frequency resolution is increased over several periods of the fundamental component to determine the harmonic oscillations.

Abstract: This is a balloon catheter having braided layer which extends generally from the proximal end of the catheter to a location distal of the balloon. In particular, it is desirable that the shaft of the catheter proximal of the balloon be stiffest at the proximal section and least stiff just proximal of the balloon. Although the catheter may be a single lumen catheter using some type of a core wire to act as a valve for inflation and deflation of the balloon, it is within the scope of the invention to include either a separate inflation/deflation lumen or one incorporated into the various concentric polymeric layers used to make up the proximal shaft. Particularly preferred is the use of an elastic, compliant balloon.
