Title: Electron spectrometer with two helical electrodes - tuned to same transmission speed and used in tandem
Inventor: HOLZAPFEL GEORG DIPL PHYS DR R
IPC: H01J49/48
Filed: 1978-02-23
Abstract: The spectrometer has two helical electrodes tuned to the same transmission speed and used in tandem. The deflected beam leaves the tandem at a voltage node after the first helix and is focussed by the external electric field produced by the second helix- of the same phase as the first. Alternatively, the beam may remain inside the tandem, being diverged by the first and converged by the second helix. The electron trap or detector is located at the voltage node between the helices and on their axis. The helices may have the same constant dia. or their diameters may vary in steps.

Title: Flat glass mfr. via float chamber - where inlet and exit speeds of glass in chamber are controlled to improve optical quality
Inventor: BARON DIETMAR
IPC: C03B5/04
Filed: 1978-10-25
Abstract: The glass is melted in a tank furnace, and then flows through a feed channel into an exit tank followed by a doser leading to a bath of molten metal forming the float chamber.

Patent DE-2907453-A1 (DE)
Inventor: SOMMER KLAUS DIPL CHEM DR
IPC: B01J19/00
Filed: 1979-02-26
Abstract: A process and apparatus for condensing solid materials such as phosphates which tend to sinter and adhere when heated in a reactor wherein the reactants are introduced into a trough-like reactor provided with at least one set of rotatable agitating paddles. Heat is supplied to the reactor by passing a heating medium, such as a molten salt or a molten metal, through one or more heating jackets on the exterior of the reactor housing. The agitating paddles press the solid material in a thin layer against the wall of the reactor housing, and the material in the layer absorbs heat from the heating medium and sinters to a hard layer. One paddle of each set of paddles is provided with a stripping knife which moves along a path closely adjacent to the exterior wall of the reaction chamber to strip sintered material from the wall of the reactor housing. Heat is also transferred to the interior of the reactor housing by circulating the peeled material through the interior region of the reactor housing.

Title: Yarn texturing device - comprises rebound crimper with short, straight construction tube leading to yarn exit
Inventor: TURNER JAMES H
IPC: D02G1/00
Filed: 1979-04-30
Abstract: A yarn texturing device effects crimping on a multifilament yarn by bouncing or rebound, using a heated fluid, such as steam under pressure. The rebound crimper head receives the yarn and texturises it with the aid of the steam fed through the pipe. The crimped yarn passes to a constriction tube contg. a blade spring. The constriction tube is straight and short, and the yarn leaves by the exit at its far end to be collected. By maintaining the constriction tube straight and short, the collection of chemical deposit or foreign matter is discouraged so that there is less likelihood of uneven crimping than in prior art. By mounting the blade-spring inside the constriction tube, protection is offered against external shock or damage.
