Date Apr. 18, 1991.In a method for filtering a suspension through a stationary filter having a vertical filter element arranged in a pressure vessel and for re-conditioning the filter after filtering, the filtrate is discharged from the bottom of the filter element during the main part of the filtering. After filtering, unfiltered suspension is discharged in a known manner from the pressure vessel later to be returned to the suspension inlet. Thereafter, back-wash is performed with another medium other than filtrate, an outlet for material deposited on the filter element being opened for removal of said material together with the back-washing medium. Preferably, before back-wash, drying of the material deposited on the filter element takes place by means of a gas medium circulating within the filtering plant.

Title: Orientation auxiliary device for persons with defective sight
Inventor: LOEFVING STEN
IPC: A61F9/08
Filed: 1996-09-24
Abstract: The electro-optical unit is adjustably fitted on a blind person stick. The output effect of the laser forms a vertical line. The optical receiver reacts when the laser light meets bar codes partly made of retro-reflecting material. The bar codes are decoded in connection with the probing of the ground surface by the user with the stick. The thus decoded information is transmitted to the user with the aid of pre-recorded words associated with the respective bar code combination. The optical receiver is so formed that it can also receive information from an external optical transmitter. The bar codes are formed so that they narrow upwardly and downwardly. If the laser light comes into contact with retro-reflecting material a comparatively powerful signal occurs in the receiver. The signal is easily detected even if the reflections are as small as five centimetres high and are located ten metres away.

Abstract: In many types of construction machines, the frame assembly comprises a rear frame that supports the engine and the majority of the drive train components and a front frame that supports the work implement and related structure. In this type of machine, the two frames are normally pinned together and the front frame is articulated with respect to the rear frame by a pair of steering cylinders to provide steering for the machine. In order to provide the required structural support for the components of the work implement and to accommodate the steering forces, the front frame is necessarily quite large. The present invention provides a front frame (12) structure that includes a pair of main side plates (62, 64) that are positioned a preselected distance (W) from one another and mount a lift arm assembly (30) therebetween to minimize the overall width of the frame assembly. The forward end portion of the front frame assembly (12) has a preselected height (H) that permits the front frame to have a low profile. These features provide a frame assembly that allows an operator exceptional visibility to the work implement (42).

Title: Treatment of metal smelt to form metal powder by atomisation
Inventor: LAMENOISE JOEL
IPC: B22D/
Filed: 1999-02-17
Abstract: A plug inserted into a hole in the die above the tap hole is progressively degraded by the smelt (3) to release a gas that causes slag to accumulate on the smelt surface.  A method for treating a metal smelt in a vessel (1) with a tap hole in a die in the vessel base comprises press-fitting a plastic plug into an elongated hole in the die above the tap hole, the elongated hole having a diameter less than that of the plug, prior to the vessel being filled with smelt. The plug is made from a material which is progressively degraded by the smelt to release a gas that rises calmly to the surface as the smelt is stirred, taking with it slag products present in the smelt, which then accumulate on the smelt surface. The die is heated before the plug has been completely degraded to expose the tap hole, following which the smelt automatically runs out through the tap hole into the heated die. An Independent claim is also included for the arrangement comprising the die and plug, the die containing a hole with a depth of 100-500 mm and a width 2-5 times that of the tap hole diameter.
