Patent DE-2952528-A1 (DE)
Inventor: LITTWIN BURKHARD DIPL PHYS
IPC: H01J17/49
Filed: 1979-12-28
Abstract: A gas discharge display device has a discharge chamber and a post-acceleration chamber which are separated by a perforated control disc having line and column conductors thereon. The post-acceleration chamber is limited at its lateral boundary by at least one spacing frame which leaves the post-acceleration chamber support-free in its active volume. The inner boundary of the lateral spacing frame substantially coincides with the outer boundary of an active luminescent screen surface which limits one side of the post-acceleration chamber, and the frame has a width such that the inner frame boundary is free of sealing material and which further maintains a separation between the outer edge regions of the potential layers on the opposite sides of the post-acceleration chamber. A high post-acceleration voltage can thus be employed in the post-acceleration chamber without producing arcing.

Title: Process and plant for melting metals in a foundry
Inventor: RASMUSSEN ANLEGGSJEF PER
IPC: F27D7/04
Filed: 1981-01-26
Abstract: A process for melting metal in a plant specially tailored to this process, in which cast blocks of metal, waste metal and alloy metal(s) are weighed out in batches of equal size which are loaded into charging buckets. These charging buckets are automatically gripped by means of a control unit, conveyed into a preheating chamber and then transported to above a melting chamber, where they are emptied. They are then returned. A new melting process begins whenever a molten batch has been poured out of the tilted smelting furnace and the smelting furnace has been returned to its normal position. During melting, all waste gases are passed into the preheating chamber, in which a constant pressure is maintained and in which overheating is avoided by feeding in fresh air in a controlled manner. The preheating time in this process is always exactly as long as the melting time, and furthermore the preheated and discharged batches are of the same size.

Patent DE-3108166-A1 (DE)
Inventor: KOGURE SHIGERU
IPC: H03H9/215
Filed: 1981-03-04
Abstract: A mode coupled tuning fork type quartz crystal vibrator utilizing two different vibrational modes is provided. The vibrator includes at least one electrode on each tuning fork arm for adjusting the resonant frequency of the main vibration and an electrode for adjusting the frequency-temperature characteristic of the vibrator. The main vibration is in the flexural mode (F1) and the sub-vibration is in the torsional mode (T0). The resonant frequency of the first overtone in the flextural mode is designated by fF and the resonant frequency of the fundamental vibration in the torsional mode is denoted by fT. The difference between fF and fT defined as  DELTA f=fF-fT determines the frequency-temperature characteristics of the mode coupled vibrator. The electrodes for adjusting fF are substantially triangular in shape and the electrodes for adjusting fT are substantially rectangular in shape. These electrodes are disposed at positions near the top of each tuning fork arm and on both principal surfaces of the vibrators. The resonant frequencies are adjusted by removing a portion of electrode material or adding a strip of metal to the electrode. Preselected oscillation frequency and frequency-temperature characteristics in the form of a cubic curve at ambient temperatures are obtained by first adjusting  DELTA f to a preselected value  DELTA fO and then adjusting fF to a preselected value fF0 at the same time maintaining  DELTA f at the value  DELTA f0.

Title: Process for producing tritium, and appliance or breeder element for carrying out the process
Inventor: DITTRICH HANS G DR ING
IPC: G21G1/06
Filed: 1981-09-02
Abstract: The invention relates to a process for producing tritium by means of a breeding process, e.g. the reaction <6>Li(n, alpha )T with neutron irradiation, and to a breeder element for said process. The purpose of the invention is to be able to generate large amounts of tritium in a simple manner. This is achieved by the following steps:   a) introduction of the fertile material (breeding material) together with a sorption material for tritium into a hollow body having a permeation-inhibiting wall,   b) irradiation of the filled hollow bodies with neutrons,   c) absorption of the bred tritium in the hollow body, d) isolation of the bred tritium, after irradiation, from the sorption material. The associated breeder element consists, from the outside to the inside, of a plurality of shells:     1) outer shell (1) of graphite,   2) permeation-inhibiting layer (2) of ceramic hard material, 3) layer of fertile material, e.g. of pure <6>Li in the form of porous alloys or salts,   4) core of sorption material (4), e.g. of porous zirconium. The advantage of the invention consists in the beneficial combination of breeding and isolating the tritium without separate isolation systems. This results in reduced environmental hazards, a higher yield, higher purity and less hazardous handling of the tritium. <IMAGE>

Patent DE-3140955-A1 (DE)
Title: Method of retouching halftone films in producing originals for printing forms
Inventor: HECK OTTO
IPC: G03F5/00
Filed: 1981-10-15
Abstract: In the method, the halftone film to be corrected or its negative is exposed, first directly and then with the insertion of a transparent layer, on a hard film, in particular a lith film, to produce a screen copy. Depending on whether the positive or the negative of the halftone film to be corrected is used, an attenuation or an intensification of the tone value is achieved. The tone value correction can be controlled since, for a given copier, the exposure time necessary to achieve a certain change in tone value can be derived from a calibration curve. The transparent layer used may either be a blank sheet which may carry a coating layer for protecting the image areas not to be retouched against a change in screen dot size, or the transparent layer used may be a halftone negative of the halftone film to be corrected, thereby making it possible to modify the gradation of the screen values within the part of the image treated. Instead of a halftone negative, it is also possible to use a sheet having phototropic properties which spontaneously builds up a certain grey level on exposure to light and later becomes clear again so that it can be reused.
