Title: Complementary communication system in the no-connection mode for asynchronous time-division network
Inventor: LESPAGNOL ALBERT
IPC: H04L5/22
Filed: 1990-06-29
Granted: 1994-10-18
Abstract: A communication system is designed to equip an asynchronous time-division network and to enable terminals linked to the network to communicate in the no-connection mode. The system comprises a ring management device and means distributed among the terminals and interfacing the terminals with the virtual ring for managing the production, reception and transmission of data cells. The ring management device is linked via the network to each of the terminals in order to control the connection/deconnection requests coming from the terminals and to supply information concerning cell routing to the terminals linked to the ring. A terminal   has a particular role as pilot and regulates the rate of the data cells in the virtual ring. Another purpose of the pilot terminal is to eliminate the altered cells. Furthermore, there is provided in each of the terminals  for limiting its rate to a maximum value.

Title: Satin stitch presser foot
Inventor: ROWLEY CLARE J
IPC: D05B29/00
Filed: 1990-08-28
Granted: 1996-06-11
Abstract: A  self-guiding  zig-zag  satin  stitch  presser edge  foot  includes  a  sole to be pressed  against  a fabric to be sewn and a fabric guide for engaging an edge of the fabric.  The fabric guide carries a thread guide  pin  which  lies  adjacent  to  the  edge  of the fabric.  The fabric guide and the thread guide pin are laterally movable, as a unit, by the positioning of a nut on a threaded shank which is fixed relative to the sole.   Extending upwardly from the fabric guide is a U-shaped  yoke  which  is  slidably  received  onto  the threaded  shank.   A nut,  which  is threaded onto the shank, is positioned within the yoke to move the fabric guide and the thread guide pin as the nut is rotated about the shank.  The sole includes a channel formed on the underside thereof rearwardly of a needle dropping hole, having a sufficient depth to permit a thickened satin-stitch hem to pass therethrough.

Title: Magnetic tape cassette having dynamic tape guide
Inventor: TANAKA MASATO
IPC: G11B15/60
Filed: 1990-12-03
Granted: 1999-07-27
Abstract: The magnetic tape cassette of the present invention has the opening portion into which the head drum having the rotary head is inserted.  The pair of tape guide members which guide the tape-like record medium so that the record medium is helically wrapped around the head drum are provided in the inside of the opening portion so as to be able to swing independently.  Thus, when the head drum is inserted into the opening portion, the two tape guide members are brought in circumferential contact with the peripheral surface of the head drum accurately.  Therefore, the recording and/or reproduction can be reliably carried out, which can increase reliability of the magnetic tape cassette.
Patent CA-2034233-C (CA)
Title: Optical cable television transmission system
Inventor: HEIDEMANN ROLF
IPC: H04J14/02
Filed: 1991-01-15
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE      The invention is based on the problem of transmitting a frequency-division multiplex signal occupying a broad frequency band, e.g., the cable television frequency band of 47-440 MHz, over an optical waveguide transmission section.  According to the invention, in the transmitting unit, the whole frequency band to be transmitted is divided into two sub-bands (FB1, FB2), and the lower sub-band (FB1) is converted by means of single-sideband amplitude modulation of a high-frequency carrier (f0) into a higher-frequency transmission frequency band, e.g. 497-688 MHz, which is less than one octave in width, based on its lowest frequency.  The lower sub-band (FB1) and the transmission frequency band produced by the conversion are converted separately into optical signals with different wavelengths (.lambda.1, .lambda.2) and are transmitted in a wavelength multiplex procedure via the optical waveguide.  Because of the limitation of less than one octave, second-order intermodulation products, which are usually formed during conversion into an optical signal, fall into unoccupied frequency regions.  A corresponding reverse processing is carried out on the receiving side.

Granted: 2001-01-23
Abstract: A method is provided for in situ decontamination of contaminated subsurface area by injection of steam into injection wells and withdrawing liquids and vapors from extraction wells under subatmospheric pressure whereby steam is passed through the contaminated area in an essentially horizontal direction. After a substantial portion of the contamination has been removed in this manner, the injection of steam is ceased, but the extraction at subatmospheric pressure is continued, to volatilize and remove the residual water and contaminants trapped in the pores of the soil. The steam injection may be periodically resumed to reheat the area and to replenish the water in the pores.

Abstract: An improved method is described for use in packaging a wide variety of products, and in particular perishable food and horticultural products. The products (12) are placed within a container (10) of the type which establishes a modified atmosphere environment therein and is cooled, as by heat transfer to a cooling element (14), which may involve the evaporation of liquid from a cooling collar partially surrounding the container. The container (10) and cooling collar (14) may be subjected to vacuum cooling. The container may include a mechanism to enhance the bulk gas transfer rate during the application of the vacuum while still maintaining the desired atmosphere within the container. The container atmosphere may be precharged with gas of a desired composition. In addition, fumigants may also be included therein.      The package is suitable for field packing applications in which the product, such as strawberries, is picked directly into the container surrounded by the cooling collar with the container and cooling collars being placed in an outer box or other receptacle. The modified atmosphere package may be sealed and palletized prior to vacuum cooling.

Abstract: Stable aqueous dispersions of polyamide resin in water comprise a surfactant and at least one amino acid of formula (I), or an anionic or cationic salt thereof, wherein "R" represents an alkylene, alkenylene or arylene group of one to ten carbon atoms and "Y" is hydrogen or a polar or non-polar ionic or non-ionic substituent, in an amount effective to improve the stability of said aqueous dispersion.      Polyamide resins have properties that render them useful in a variety of applications, including coatings, adhesives and printing inks. Owing particularly to the high melting points and the insolubility of polyamide resins, however there have been difficulties in the prior art in using polyamide resins in these applications. The stable aqueous dispersions of the present invention facilitate these uses of polyamide resins.

Abstract: A transformer isolates a control circuit from a FET, the control circuit including a clock generator for providing, when en-abled, a clock signal to the transformer primary. A PWM input selectively disables the clock generator from providing the clock signal to the transformer primary. The transformer secondary is connected in a full wave centertap configuration for providing a full wave rectified version of the clock signal, the full wave rectified version being a relatively constant DC voltage signal suppli-ed at one level to the FET to turn on the FET when the clock generator is enabled to provide the clock signal to the primary. The centertap configuration provides a relatively constant DC voltage signal at a second level to the FET to turn off the FET when the clock generator is disabled by the PWM input from providing the clock signal to the primary.
