Title: Sludge drying
IPC: C02F11/13
Filed: 1992-05-14
Abstract: To dry sludge matter, it is carried by at least one continuous conveyor through a radiant heat zone which initially raises its temp. to a point where it starts to become tacky. In a second zone, the radiant heat is structured to convert the tacky condition and change the material into a loose structure which can be ejected from the conveyor.     Also claimed is an assembly with an open conveyor channel with a screw conveyor and a radiant heat assembly with at least one heat radiator, followed by a conveyor. The conveyor channel has two heating zones, with the zone change at the point where the sludge starts to become tacky. The speed of material travel, material vol. and the screw conveyor speed are structured so that the sludge remains in a suitable state to be carried by the screw conveyor. The following conveyor carries the material through a final drying stage.

Title: Gas-tight alkaline metal hydride accumulator - has electrolyte free hydridable negative electrode portions to increase hydrogen take up rate on polarity reversal
Inventor: DEHMELT KLAUS DIPL ING
IPC: H01M10/34
Filed: 1992-08-26
Abstract: A gas-tight alkaline accumulator has its electrolyte infiltrated in the capillary pores of the electrodes and the separator and has a negative electrode contg. hydridable material, hydrogen being evolved, after full discharge and polarity reversal at the electrode which was the positive electrode before discharge, while the negative electrode still has a hydride content. The novelty is that portions of the hydridable negative electrode are electrolyte-free and dry during accumulator operation and that the hydrogen, produced at the originally positive electrode and that the hydrogen produced at the originally positive electrode on polarity reversal, is taken up by the hydridable material at these portions at low pressure without involving electrolyte, while simultaneously hydrogen of the hydridable material is electrochemically oxidised to water with release of electrons in the region of the electrolyte-contg. reaction face of the negative electrode. ADVANTAGE - Polarity reversal resistance, esp. on discharge at high current, is increased.

Patent DE-4234740-A1 (DE)
Inventor: HENTZE JOACHIM
IPC: G02B5/18
Filed: 1992-10-15
Abstract: In a process for producing optically effective structures, in particular lenses and lens arrays such as prisms, a stepped, optionally effective base structure (10) is formed at the surface of a substrate (1) by at least one masking step (MS) followed by an etching step (AS). The base structure (10) is then heated in a melting step (SS) until the substrate is melted and is smoothed by superficial capillary forces of the molten substrate. For that purpose, the base structure (10) is introduced in a vacuum chamber (3); there it is continuously moved with respect to an electron beam (4), in a band-like manner, and at the same time such an energy intensity is applied to it that a melting zone is produced whose depth corresponds to the height of at least one step of the stepped base structure (10). Also disclosed are a device for carrying out this process and novel products thus created.

Title: Shrouding walls for protection of warp winder operator from escaping dust - are pref. positioned at rear with upper covering wall and swing away together when door is opened to allow access
Inventor: BOLLEN MANFRED
IPC: B65H54/72
Filed: 1993-04-02
Abstract: The shrouding walls (7, 7') for the warp winder (1), and the upper covering wall, can swing away from the winder (1). A shrouding wall (9), with pref. at least one door, is at the rear of the winder assembly. The walls (7, 7') and the upper covering wall are pref. swung clear when the door (10) slides open. A guide wall is pref. below the line of warp yarn travel from the creel to the winder which, with the upper wall, forms a tapering channel towards the winding beam against a yarn deflection roller (12) over the winding beam (2), with an air-sealed gap between the guide wall and the deflection roller (12). A comb (22) is pref. in front of the yarn deflection roller (12). The narrowest cross section of the tapering channel is pref. at the comb (22) and/or the yarn deflection roller (12). The channel opens into a suction port connected to a suction unit at the upper covering wall, to swing upwards with the cover. The suction opening is at a wall section to lie closely against the yarn deflection roller (12). The cover has a transparent section to view the yarn passage. The side walls (7, 7') pivot on vertical axes (14, 14'), with a greater gap between them than the winder (1) width. When closed, the walls (7, 7') are against the side flanks (16, 16') of the winder, and when open, give a passage to the creel. USE/ADVANTAGE - Used for the protection of operatives from dust escaping into the ambient atmos., and also to prevent air streams affecting the passage of the yarns from the creel to the winding beam. The walls give an effective protection and, when the winder is at rest, can be swung clear to give access.
