Patent NO-161622-C (NO)
Inventor: HEFNER ROBERT E JR
IPC: C08G59/04
Filed: 1985-10-01
Abstract: This invention pertains to a process for preparing hydroxyaromatic oligomers containing triazine groups and oxazoline groups. The process is characterized by (I) reacting (A) a material having an average of more than one aromatic hydroxyl group per molecule with (B) a cyanogen halide such as cyanogen bromide in the presence of a base and recovering a mixture of cyanate-containing products and unreacted (A) materials, (II) co-oligomerizing the product resulting from (I) with an epoxy resin in the presence of a suitable co-oligomerization catalyst. This invention also pertains to a process for preparing epoxy resins containing both triazine groups and oxazoline groups by epoxidizing a hydroxyaromatic material in a conventional manner by reaction with an epihalohydrin with subsequent dehydrohalogenation with a basic-acting material and finally recovering the resultant glycidyl ether product, characterized in that the hydroxyaromatic material is the resultant co-oligomerization product from step (II) of the earlier process.

Inventor: VIEGENER WALTER
IPC: E03C1/29
Filed: 1989-10-27
Abstract: The discharger armature, which is used especially for shower bottoms, consists of a housing (7) provided with an inflow opening, a discharge socket (22) and a fastening flange (6) and of an immersion pipe (15) inserted into the housing and delimiting the inflow opening. The housing (7) contains an outer annular channel (19) and an upper discharge channel (21). The fastening flange (6) of the housing, which is fixed to the edge of a base opening (2) in the shower bottom, is arranged offset downwards with respect to the upper housing wall (13), which delimits the upper discharge channel (21). The bottom (20) of the outer annular channel (19) is inclined towards the discharge socket (22). As a result of this inclination of the bottom of the outer annular channel, in the case of a large flow cross-section of the annular channel, on the one hand, the discharging capacity is improved and, on the other hand, self-cleaning of the discharger armature is achieved. The discharger armature has a low overall height and a high throughput capacity. <IMAGE>

IPC: A47K10/38
Filed: 1990-01-15
Abstract: A paper dispenser is furnished with one or more turnable or tiltable cutting or tearing off device, equipped with serrated or jagged edges. When inactive, the cutting edge is held by a spring or by force of gravity in a safe or innocuous position. As a drawing force is applied to the paper web coming out of the dispenser, the cutting or tearing off device is turned or tilted so that the serrations of the cutting edge come into contact with the paper web. When a portion of the web is torn off, the jagged edge returns to its shielded position. The cutting or tearing off device can be directly actuated by the paper web, or via an intermediate element.

Abstract: An electret condenser microphone includes a cup-shaped metallic case having an apertured end wall, a tubular metal ring received in the metallic case, a vibratory dia-phragm having on its one surface a deposited metal film and bonded to an end face of the tubular metal ring in confront-ing relation to the end wall with an air gap defined there-between, and a condenser composed of a movable electrode and a fixed counter electrode, the fixed counter electrode comprising at least a part of the end wall of the metallic case while the movable electrode comprises the vibratory diaphragm.  Partly because the end wall of the metallic case serves as the fixed electrode, and partly because the vibra-tory diaphragm is bonded to the end face of the metal ring, the number of the components of the microphone is relatively small.  With this small number of components, the microphone is simple in construction and can be manufactured at a low cost, and further has a relatively large rear cavity behind the vibratory diaphragm, which improves the sensitivity of the microphone.

Title: Colour sequential illumination system
Inventor: HOLDEN JOHN GRAHAM
IPC: H01J61/42
Filed: 1991-10-11
Granted: 2002-08-20
Abstract: A colour sequential illumination system, such as, for example, a backlighting system for a liquid crystal display (LCD), comprises lamps for emitting blue, red and green light.      The red and green light is provided by lamps including fluorescent dyes having optical decay times similar to a phosphor material used to provide the blue light. In this manner, the blue, red and green emissions can be fully synchronised with electrical signals used to energise the lamps, enhancing colour range and colour quality. Furthermore, if the fluorescent dyes are carried in plastics materials, then trapping and concentration of the light generated may also be achieved, providing enhanced brightness fox the LCD for a given power input.

Filed: 1992-03-30
Granted: 1995-12-19
Abstract: A spacer for separating panes of glass in a sealed window unit is formed of a thermosetting resin reinforced longitudinally with continuously extending glass fibers. A layer of a foil material is introduced into the part during the pultrusion process so that the foil is embedded within the pact and defines a moisture impermeable layer in the outer wall of the part. The foil can be carried into the part on a layer of paper or polyester which combines with the resin in a bonding action. The rovings forming a top surface of the spacer have one or two of the rovings introduced without impregnation by the resin so as to produce a more permeable central section of the top surface.
