Patent CA-2182538-A1 (CA)
Inventor: MACKAY IAIN
IPC: H05B37/02
Filed: 1996-08-01
Abstract: An outdoor ground lighting system that includes one or more low voltage lamp units, provided from a step down transformer connectable to a high voltage AC power supply, and an on/off timer operative to turn the lamps on for a selected time period during hours of darkness. Added to this known system is a secondary low voltage switching system that includes a solenoid operated normally open switch in which the switch is shunted across the timer controlled switch. A detector detects the presence of a person or the like in the field of view of the detector and provides an output signal in response thereto. The signal activates the solenoid thereby closing the switch to turn on the lamps when the timer is in the off cycle. The secondary switching system enhances the garden lighting system by providing a security lighting system when the timer is in an off mode.

Title: Scintillation crystals having reduced afterglow and methods of making the same
Inventor: MURPHY HAROLD J
IPC: C09K11/00
Filed: 1997-02-20
Abstract: Methods of making a scintillation crystal having reduced afterglow include preparing a crystal melt according to the Czochralsky technique and doping the melt with an element or a compound which reduces afterglow without significantly reducing the luminescence light output of the crystal grown in the melt. Experiments have shown that doping the melt with any one of calcium, cobalt, germanium, niobium, sodium, and chromium significantly reduces afterglow without unduly reducing the luminescence light output of the crystal. The presently preferred dopant is cobalt, which is added to the melt in concentrations of approximately 10ppm to 50ppm. Crystals made according to the method of the invention exhibit significantly less afterglow than crystals made from the same raw materials without doping. By choice of the proper concentration of dopant, the light output of the crystal during luminescence is not adversely affected.

Title: Methods to fabricate dense wavelength division multiplexers
Inventor: QIU CINDY XING
IPC: G02B6/36
Filed: 1997-03-14
Abstract: Methods for the fabrication of dense wavelength division multiplexers (DWDM) are disclosed. In one embodi-ment, an array of micro membranes and an array of cavities for optical fibers are etched in a substrate. The distance between major surfaces of adjacent micro membranes is con-trolled during the etching step. Multilayer narrow bandpass filters are then deposited on all micro membranes simultaneously by vacuum deposition methods. Due to the controlled separation between adjacent micro membranes, the central wavelength of transmission either increases or decreases from one membrane to another. In another embodi-ment, a micro machined structure containing a plurality of cavities and a slot for a variable narrow band pass filter is fabricated. The variable narrow band pass filter is aligned with respect to the optical fibers to obtain a WDM.

Title: Method of video information transmission, as well as an information carrier, a device for receiving and a device for transmitting video information
Inventor: DE HAAN WIEBE
IPC: H04N5/92
Filed: 1996-07-12
Abstract: Video information intended to be reproduced on a television screen (1) often includes additional information such as graphics information (3) or subtitles (4) in addition to the main information such as film images (2). This additional information is transmitted separately, so that the user may choose whether the additional information is to be displayed or not. In the disclosed method the transmitted video signal comprises information relating to the duration (25) for which the additional information is to remain on the display. With this method the additional information can be displayed exactly for the duration of the desired time. When a video disc or tape is used for transferring video information, this is advantageous in trick modes, such as Fast Forward.

Abstract: A process (1) for the separation of cellulosic fibres from non-cellulosic fractions in paper product is disclosed. The paper product comprises cellulosic fibres and at least one of thermoplastic polymer and metallic foil.  The process (1) comprises vigorously admixing paper product in aqueous solution (3) in a vessel (2), the paper product being in a comminuted form and the vessel (2) being such that the solution (3) has a surface (11) within the vessel (2). The admixing is such that it is effective for at least partial separation of cellulosic fibres from thermoplastic polymer and metallic foil and to form a suspension of cellulosic fibres so separated in the aqueous solution (3). A fraction (13) comprised of thermoplastic polymer and/or metallic foil is separated from the surface (11) of the aqueous solution (3) in the vessel (2). The separation is carried out by using a bucket conveyer (6) extending below the surface (11) of the aqueous solution (3) and discharging the fraction (13) outside of said vessel (2). The process is useful for separating coated paperboard into its components, e.g. for recycling of beverage containers.

Title: Pharmaceutical combination preparation for hormonal contraception
Inventor: SPONA JUERGEN
IPC: A61K31/57
Filed: 1996-04-04
Abstract: A combined pharmaceutical preparation has two sequential administration hormonal components that are separately packed in a packaging unit. Each hormonal component consists of a plurality of separately packed daily dosage units that may be individually withdrawn from the package. A first hormonal component contains as hormonal active substance a combination of an oestrogen preparation and of a gestagen preparation in a dose that is at least sufficient to inhibit ovulation. The second hormonal component contains as hormonal active substance only an oestrogen preparation. The first hormonal component comprises 23 or 24 daily units and the second hormonal component comprises 4, 3, or 2 daily units. Between both hormonal components are placed 2 or 1 active substance-free daily units (placebos) or are indicated 2 or 1 pill-free days. The total number of hormonal daily units and active substance-free daily units or pill-free days equals the total number of days in the desired cycle that has however at least 28 days. This combined preparation for feminine contraception has an as low as possible oestrogen content in each individual dosing unit and also a low total hormone content per administration cycle, while having a high contraceptive safety, a low incidence of follicle development, and allowing an irreproachable cycle control and reliably avoiding spotting and undesirable side effects.

La composition photosensible peut être appliquée sur un substrat approprié à des applications dans lesquelles on utilise une plaque d'impression planographique. L'irradiation par imagerie entraîne le photodurcissement des régions irradiées par la lumière, les rend insolubles dans des milieux aqueux et organiques, alors que les régions non irradiées par la lumière restent fortement solubles/dispersibles. Les plaques d'impression selon l'invention ne requièrent pas de traitement avant d'être exploitées sur une presse.
