Title: Quality control tester for incandescent lamps - places two lamps in parallel to form first test unit and forms second test unit from two first units also in parallel
Inventor: HARNISCHMACHER FRIEDHELM
IPC: G01R31/44
Filed: 1990-12-17
Abstract: To test sixteen lamps, they are placed in pairs (30,31; 32,33; 34,35; 36,37....) to form first units (46 to 49). These units in turn are placed in parallel to form second test units (54,55....). In a further stage, each pair of second units can be switched together to form a third test unit (57,58). Finally, all the pairs of units are switched together in a single large assembly (60) supplied from a current source (61). The current from the latter flows equally through all the lamps so that each is subjected to the same test voltage. USE - Testing any number of lamps under same conditions.

Patent DE-4119538-A1 (DE)
Title: Impregnation of fibres
Inventor: CUSTER MILTON F
IPC: B29B15/12
Filed: 1991-06-13
Abstract: To completely impregnate fibrous material formed into sheets of unidirectional parallel filaments with a high viscosity resin of linear long chain molecules the resin is softened by heat and applied to both faces (26,28) of the fibrous material (4). The material is moved forward and a low pressure not exceeding 70 kpa applied to the resin which is kept to a coating thickness not more than 1.2 times the material thickness. A shear force is applied to the resin coating the material by its movement through a restricted width passage (16). The shear force lowers the resin viscosity, causes the long chain molecules to align themselves with the fibres and penetrate the material to fully integrate it. Also claimed is the appts. containing the shearing passage (16) that has a width with a play of approximately 10 microns with the material passing through it.

Patent DE-4136883-A1 (DE)
Inventor: GRUBER HEINZ
IPC: E21B17/00
Filed: 1991-11-09
Abstract: In order to provide a grouted bored anchor which can be used in particular in cohesive soils and which at the same time has especially reliable corrosion protection in the set state, it is proposed to use as a drill tube and as a grouting tube a basic body provided with a uniform thread at least on the outside over its entire length. The basic body is provided with a continuous longitudinal bore and has a helix (20) on the outside which - as viewed in cross-section - has a triangular configuration, thus tapering radially outwards, and is of hollow design and the helix surfaces of which tangentially adjoin the facing peripheral sides of the basic body. The helix (20) has a pitch of 1 m to 3 m and, during the drilling operation, which is preferably carried out with air as the flushing medium, serves to discharge the air laden with released particles. When the basic body is being grouted in place, the helix serves to accurately guide it concentrically in the borehole and thus obtain an in particular overall covering, extending uniformly over the entire length of the drill tube, with an anchoring mortar or a comparable hardenable medium so that the drill tube is arranged in such a way as to be protected in an especially reliable manner against corrosive effects from the surrounding rock. The helix (20) extends uniformly over the entire length of the drill stem (19). <IMAGE>

Pref. the process soln. is cooled to temp. of 274-293 K, and the recirculated air is cooled. The processing station with suction extn. is at the end of the assembly. The air curtain (14), covering the openings, for material (2) insertion and extraction, is switched off while material is passed through them, and air is extracted (8) from the station while material (2) is moved through, and the extracted air is released or passed to another station than for air curtains (14). While material (2) is moved through the disconnected air curtains, the air recirculation system is switched off, and air extracted by suction (8) is released. The recirculated air passes through an air washer (16), with droplet extractor (17) before or after it. The fluid (18) used in the air washer (16), whether alkali or acid, is cooled and recirculated and cleaned of any hazardous matter carried in it. Heat pump is used to generate the required cooling capacity, and its generated heat is used for heating bath at raised temp. in the assembly (1) or in other assemblies. USE/ADVANTAGE - The system is used for electro-plating and similar surface treatment applications where there is liq. chemical action.
