Patent DE-3633356-A1 (DE)
Title: Roadway-support machine with integrated drilling arm
IPC: E21D11/40
Filed: 1986-10-01
Abstract: For work in roadway driving in underground mining and tunnelling, a roadway-support machine is provided, in the heavy-load beam or frame supporting structure of which a drilling apparatus is integrated in such a way that it does not constitute an obstruction during the support work and other auxiliary work but on the other hand can be operated during the drilling work in such a way that a disadvantageous drilling shadow is not a hindrance. The drilling apparatus with its drilling arm is put centrally into the frame supporting structure and has a drill carriage which is movable on the longitudinal girders, specifically between the boom arms which carry the support-setting device and the working platform. The drill carriage with the drilling apparatus thereby reaches so far forward that these individual parts of the working platform and support-setting device no longer constitute an obstruction during drilling operation. In addition, the working platform can be retracted in the longitudinal direction of the roadway so that it cannot hinder the swivelling and rotating of the drilling arm and the other parts of the drilling apparatus. <IMAGE>
Patent DE-3633469-A1 (DE)
Title: Laser having distributed feedback
Inventor: SZATMARI SANDOR DIPL PHYS DR
IPC: H01S3/094
Filed: 1986-10-01
Abstract: A laser which operates with distributed feedback is described, which contains a laser medium (which can be excited by pumping radiation) and a pumping radiation beam path in which a diffraction grating (1) is located which acts as a beam divider and splits an incident pumping radiation beam into two beam elements, as well as an optical arrangement for combining the beam elements, producing an interference figure in a surface which runs in the laser medium. The optical arrangement images the diffraction grating (1) in an essentially error-free manner in the said surface and may contain a second diffraction grating (2). The imaging ensures high contrast of the interference figure even in the case of a relatively wide spectral bandwidth of the pumping radiation, which enables the generation of very short laser radiation pulses, which are essentially free of any substructure. <IMAGE>

Title: Electronic celestial globe
Inventor: SCHUMACHER HORST
IPC: G09B27/06
Filed: 1986-10-23
Abstract: The electronic celestial globe is a three-dimensional rotatable precision instrument having real-time progression with advancing date and time display, daily rising and setting of the stars and moon phases with realistic inclination angle with respect to the earth. Familiarisation is facilitated by clicking-on the stars, planets, nebula, star clusters and galaxies. The items of information which can be called up give name, scientific designation, brightness, distance in light years, etc. 30,000 years, from 1.1.15,000 BC to 31.12.15,000 AD, can thus be astronomically retraced and predicted for the past, present and future. The colour diagram gives information on physical parameters such as colour, spectral type, luminosity, diameter, temperature and mass of the stars. The planetarium circuit, likewise with advancing date and time display (a rate of 1 day for every 3 seconds), shows the orbital paths of the planetary movements with their standstills, return movements and loop formations. Enlargements, networks of parallels and meridians, meteor showers, connection lines of the stars appear as required. Illustration and use of the coordinate systems are contained in the accompanying brochure, as are historical dates and descriptions of particular star and planet constellations, retraceable by data regarding date, time and geographical location.

Title: Method and device for thermally combating the infestation with mites of bee colonies
Inventor: GLUECK GUENTHER JOSEF
IPC: A01K51/00
Filed: 1986-12-22
Abstract: For combating parasitic mites, in particular Varroa mites in bee colonies, an adjustable hot air flow at a temperature of approximately 42-48@C is supplied into the bee dwelling of the bee colony affected or into a treatment box, which flow induces difficulty in breathing in the parasite, dries it out, at the same time blows it off of the bees and sticks it to an adhesive insert under the wire mesh bottom of the treatment box. The hot air flow breaks up the bee cluster and prevents a renewed cluster formation during the treatment. The device for implementing the method has a hot air blower (6) which is mounted on the box (1) of the bee colony and can be controlled in the heating effect and air quantity. <IMAGE>

Title: Ceiling light, in particular for living and working rooms
Inventor: KALZE FRANZ JOSEF DIPL ING
IPC: F21Y103/37
Filed: 1987-01-23
Abstract: The invention relates to a ceiling light for living and working rooms having a pot-shaped reflector and a plurality of finger-shaped fluorescent tubes. The reflector is bounded in the median sections along the optical axis by two parabola branches, the centre axes of which run at an acute angle with respect to each other. The centre axes of these parabola branches meet at the optical axis of the light. In order to reduce the glare for observers standing further away from the light in the direction of the centre axes of the individual fluorescent tubes, the reflectors have in the regions neighbouring the light-emitting surface and the median plane passing through the optical axis and parallel to the centre axes of the fluorescent tubes a smaller lead angle than the other reflector regions in the same sectional plane running perpendicularly with respect to the optical axis. These regions are preferably formed as planar areas.
