Title: Arc discharge lamp with spring-mounted arc tube, shroud and frame
Inventor: HUNTER SCOTT R
IPC: H01J61/34
Filed: 1991-11-25
Abstract: A metal halide arc discharge lamp includes an arc tube and a light-transmissive shroud mounted within a lamp envelope. The arc tube and the shroud are mechanically attached to a frame. The frame is mechanically supported within the lamp envelope by resilient spring members. Since the frame is mechanically and electrically isolated from the lamp stem, leakage current between the frame and the electrical inleads is eliminated, thereby reducing sodium loss from the arc tube and extending the operating life of the lamp. The spring-mounted construction enables the lamp to withstand mechanical shock and vibration.

Patent CA-2110186-A1 (CA)
Inventor: TROKHAN PAUL D
IPC: D21F11/00
Filed: 1992-06-17
Abstract: Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with dif-ferent flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.

IPC: H04R5/02
Filed: 1994-03-02
Abstract: A casing for an audiovisual equipment presents an outer appearance giving the impression of integrating a hole area formed of a plurality of sound transmitting fine holes with the casing, thereby making the hole area unnoticeable. This allows a viewer to easily concentrate on the screen by eliminating anything noticeable from the area surrounding the screen, and also gives the outside of the casing a luxurious appearance. In order to make the hole area unnoticeable, maintain good volume and quality of sound from the speaker, and arrange the diameter ~d mm of the tapered fine holes to be practically the smallest, the relationship between the diameter ~d mm and the thickness T mm of the casing must be expressed by the following formula: (1/6) x T mm ~ ~d mm ~ 0.5 mm. When the fine holes are formed to be straight, the relationship between the diameter ~ds mm and the thickness tmm of the casing must be expressed by the following formula: (1/5) x t mm ~ ~ds mm ~ 0.5 mm.

Title: Treatment of bleach plant effluents
Inventor: LINDBERG HANS G
IPC: D21C11/04
Filed: 1994-03-07
Abstract: The removal of bleaching chemical-consuming metals from treatment fluids in a cellulose pulp mill is facilitated by treating the pulp in an acidic or neutral stage to dissolve metals, washing or thickening the pulp to produce a filtrate containing dissolved metals, and then using an alkali liquid to adjust the pH of the filtrate to cause dissolved metals to precipitate. The alkali liquid is pretreated with carbon dioxide to reduce the sulfide content and increase the carbonate content thereof, preferred alkali liquids being green liquor and white liquor. The reduced-metal content filtrate is used in the bleach plant of the pulp mill, to make bleaching chemicals, as a wash liquid, etc. Treatment of the alkali liquid with carbon dioxide is typically practised dy scrubbing the liquor with carbon dioxide gas, for example, using a plate column scrubber or a stationary packing scrubber.
