Abstract: Disjoncteur à moyenne ou haute tension à autosoufflage d'arc comprenant une enveloppe étanche remplie d'un gaz diélectrique à l'intérieur de laquelle sont placés un premier contact semi-fixe, électriquement relié à une première prise de courant et un second contact mobile, électriquement relié à une seconde prise de courant et mécaniquement relié à un organe de manoeuvre. Le contact semi-fixe est solidaire d'un piston se déplaçant dans un cylindre, le piston délimitant dans ledit cylindre un premier volume du côté de la zone d'arc et un second volume, le contact semi-fixe étant soumis à l'action d'un ressort tendant à déplacer le contact semi-fixe dans le même sens que le contact mobile lors d'une opération de déclenchement. Le disjoncteur comprend des éléments pour limiter, au cours d'une opération de déclenchement, la vitesse et l'amplitude du mouvement du piston dans le sens opposé à celui de la détente du ressort. Les mêmes éléments permettent une injection de gaz non pollué sur la zone des contacts d'arc lors de l'opération de réenclenchement succédant à ladite opération de déclenchement.

Patent CA-2042447-C (CA)
Title: Control of microsporogenesis by externally inducible promoter sequences
Inventor: ALBERTSEN MARC C
IPC: C07K14/415
Filed: 1991-05-13
Granted: 1999-09-28
Abstract: An inducible promoter is used to regulate expression of a gene which is known to be critical in microsporogenesis, i.e., the production of pollen. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.

Abstract: A multilayered tubular packaging casing for pasty matter, in particular synthetic sausage casing, on a polyamide basis, is comprised of an outer layer based on aliphatic polyamide, aliphatic copolyamide or a polymer blend comprising at least one of these compounds; a central layer which is impermeable to water vapour and comprises a polyolefin and an adhesion-promoting component; and an inner layer which preferably is impermeable to oxygen and is based tin aliphatic and/or partially aromatic poly-amides and/or aliphatic and/or partially aromatic copolyamides.      The casing can be stuffed with sausage meat in a tight and crease-free manner, without bulging or delamination of the individual layers. Due to improved water vapour barrier properties, scalded sausages surrounded by the casings can be stored at least eight weeks without substantial weight loss or crease formation. As a result of the improved oxygen barrier properties, discolouration of liverwurst-type stuffings is observed later than for casings previously known.

Title: Frequency converter circuit
Inventor: TODA YOSHIFUMI
IPC: H03J7/06
Filed: 1992-08-11
Granted: 1999-01-05
Abstract: A  frequency converter circuit which includes a first frequency conversion unit which mixes a received signal and a first local oscillation signal to produce a first intermediate frequency signal and a second frequency conversion unit which mixes the first intermediate frequency signal and a second local oscillation signal to produce a second intermediate frequency signal. Here, the first frequency deviation included in the first local oscillation signal and the second frequency deviation included in the second local oscillation signal are combined and applied to the reference oscillation unit. The oscillation frequency of the reference oscillation unit is subjected to feedback control so that the combined frequency deviation becomes zero. This feedback is formed so that a first and second local oscillation signals are produced based on reference signals obtained by dividing a reference signal having the oscillation frequency by a first dividing ratio and a second dividing ratio.

Title: Variable control, current sensing ballast
Inventor: LESTICIAN GUY J
IPC: H05B41/285
Filed: 1993-06-01
Granted: 1999-10-12
Abstract: The present invention is directed to an electronic ballast device for the control of gas discharge lamps. The device is comprised of a housing unit with electronic circuitry and related components. The device accepts a.c. power and rectifies it into various low d.c. voltages to power the electronic circuitry, and to one or more high d.c. voltages to supply power for the lamps. Both the low d.c. voltages and the high d.c. voltages can be supplied directly, eliminating the need to rectify a.c. power. The device switches a d.c. voltage such that a high frequency signal is generated. Because of the choice of output transformers matched to the high frequency (about 38 kHz) and the ability to change frequency slightly to achieve proper current, the device can accept various lamp sizes without modification. The ballast can also dim the lamps by increasing the frequency. The device can be remotely controlled.

Abstract: A setting means sets variables for expressing the process model,  a target thickness value of  the rolled material, a target interstand tension value of the rolled material, variables for responses of the thickness and the interstand tension and variables for adjusting the responses  of  a  control  system  for  controlling  the thickness and the interstand tension.   A control gain arithmetic means obtains control gains as numeric values by  substituting  the  set  variables  into  predetermined control gain operation expressions.  A control arithmetic means calculates the speed command values and the roll gap command values for causing the thickness to follow up the target thickness and the interstand tension to follow up  the  target  interstand  tension  while  reducing  an interaction  between  the  thickness  and  the  interstand tension by use of the calculated control gains.
