Title: Probe for expanding tube ends within tube plates
Inventor: BITTEL KARL DIPL ING
IPC: B21D39/20
Filed: 1987-08-21
Abstract: The probe can be employed for the pressure-tight fixing of tube ends in tube plates in the chemical industry and in general machine construction. The aim of the invention is to fix tubes without leaks and under high pressures in the holes in the tube plates and to do this in a manner which is simple to carry out and ensures maximum life for the probe and the sealing elements used. The object is to fix the components to be processed pressure-tightly in a manner largely independent of manufacturing tolerances of these components. According to the invention, the object is achieved in that the probe is inserted into the tube end to be fixed and subjected to the predetermined pressure and that, after the expansion process, the sealing elements return to their initial position. The probe is removed from the tube end and can then be pushed into the next tube to be expanded. A known pressure generator is used to generate the working pressure. The area of application is preferably the production of tubular heat exchangers. <IMAGE>

Title: Sand cooler with vibratory screen
Inventor: BAUER HANS
IPC: F27D15/02
Filed: 1987-10-17
Abstract: To recover heat from thermally reconditioned bulk material, particularly in the case of regenerated used foundry sand, use is made of ripped-pipe coolers. In order to obtain good heat transfer between the bulk material, which is moving under the effect of gravity, and the cooling surfaces, a uniformly good ability for free flow of the bulk material is a necessary prerequisite, as it is also to prevent blockage of the cooler. According to the invention, this is achieved by means of a vibratory screen (5) which is arranged before the cooling surfaces (2, 3) and which separate out and discharges the oversize and is integrated into the cooler housing (1). <IMAGE>

Title: Adjusting device for the impression hammer of a printing mechanism in typewriters or office machines of similar design
Inventor: SCHWEIZER HORST ING GRAD
IPC: B41J9/127
Filed: 1988-07-01
Abstract: Production tolerances in daisywheel typewriters, which influence the height of the daisywheel relative to the roller platen and the inclination of the impression hammer relative to the roller platen cause the printed characters to be printed either too thickly at the top or too thinly at the bottom or too thinly at the top and too thickly at the bottom. This error is balanced out according to the invention in that the swivel lever (8) consists of an elastically deformable material and has, between the head (7) of the impression hammer and the bearing bore (16), an adjusting element by means of which the swivel lever (8) can be bent within its boundaries of elasticity in such a way that the inclination of the impression surface (14) of the head (7) of the impression hammer relative to the roller platen (11) can be enlarged or reduced. In an advantageous design, this adjusting element consists of a hollow adjusting plate (20) whose free ends (21, 22) can be pressed against the swivel lever (8) by means of an adjusting screw (24) which engages in the raised part (23) of the adjusting plate (20). By simply turning the adjusting screw to the right or left, the inclination of the impression surface (14) of the impression hammer (8) relative to the roller platen is enlarged or reduced and the printing of the types can thus be increased either at the bottom or at the top. <IMAGE>

Patent DE-3836679-A1 (DE)
Title: Process for the gas-tight and liquid-tight closure of tubular components
IPC: H01R13/52
Filed: 1988-10-28
Abstract: The invention relates to a process for the gas-tight and liquid-tight closure of tubular components. In this arrangement, there is inserted, into the free end of the tubular component, an elastic sealing element which, by means of a press seal, shuts off the interior of the tubular component from the surrounding atmosphere. The characterising feature of the invention is in that a sealing element which is reduced in diameter, by stretching and freezing in the stretching stress, with respect to the internal width of the tubular component is pushed into the interior diameter of said tubular component. After the pushing-in procedure, the sealing element, by virtue of releasing the frozen-in stretching stress, is fixed in its sealing seat on the inner wall of the tubular component via the contact-pressure forces which have become free with the expansion.
