Title: Process for converting barium from heavy spar (barytes, barite) into an aqueous solution
Inventor: SIEPERT GERD DR
IPC: B01D53/50
Filed: 1987-02-28
Abstract: Heavy spar is used as raw material for the preparation of barium compounds. The heavy spar is reductively roasted with coal and a liquor is produced from the barium sulphide-containing reaction product by addition of water. Sulphur dioxide-containing waste gas is formed in the reduction of the heavy spar. The new process provides for the removal of the sulphur dioxide from the waste gas without giving undesired residues. The waste gas is scrubbed with a substream of the liquor. The used scrubbing liquid is, after removing the solids, recombined with the main stream of the liquor. The solids, comprising barium sulphite, is mixed into the starting material and roasted together with this. Preparation of barium compounds, in particular lithopones. <IMAGE>

Title: Device for sealing off the saw-blade gap between the push-piece and the casing of a jigsaw
Inventor: OCHS HUBERT DIPL ING
IPC: F16J15/52
Filed: 1987-04-18
Abstract: In known jigsaws, an excessive amount of dust penetrates through the saw-blade gap between push-piece and casing as a result of inadequate action of the seals used, in particular when working with the jigsaw "on its head" and when the push-piece performs an orbital movement (pendulum-lift movement). In order largely to eliminate the penetration of sawdust and the like through the sealing gap into the gearing space, the sealing-off device is constructed as a diaphragm seal (3) which is equipped with a reinforcing ring (3) for installation into the casing (1) of the jigsaw, is connected to a sliding ring (4) concentrically enclosing the push-piece (5) and has an annular cutting edge (4') on its outside. With such a sealing-off device, the accumulation of dust in the region of the sealing gap and also a widening of the sealing gap during orbital movement are, in particular, also prevented. <IMAGE>

Patent DE-3716988-A1 (DE)
Inventor: TAM KWOK CHEONG
IPC: G01N23/18
Filed: 1987-05-21
Abstract: The accuracy of limited-angle x-ray computerized tomography scannings is improved by incorporating additional a priori information on the object. In industrial nondestructive testing and other situations the object A contains a medium which is the dominant component whose density is known; flaws 11 inside the medium are to be imaged. The contribution of the medium is eliminated and an image is reconstructed which is the difference between the original object and a hypothetical object made up entirely of the medium which has the same boundary as the original object. Calculated projections of the hypothetical object at various scan angles are subtracted from measured projections to yield difference projections di. The latter are backprojected to derive image strips to which the flaws are confined and these are overlapped to construct a region enclosing the flaws. Using the difference projections and flaw- enclosing regions, the shape and density of the flaws are reconstructed by limited-angle reconstruction algorithms. <IMAGE>

Inventor: SCHELLENBACH FRANK
IPC: B29L1/00
Filed: 1987-06-04
Abstract: An injection core for two-component injection moulding, in particular of plastic stoppers for bottles and similar containers, solves the problem caused by the fact that injection cores in a single piece can only be moved with difficulty, if at all, a predetermined distance away from the first injected body, because of the design of the latter, in order to create a gap for injecting the second body. The injection core is composed of a first (1) and of a second (2) partial cores. The first partial core can be moved a predetermined distance (A, A') away from the first injected body after injecting the first substance, and the second substance can then be injected in the gap thus obtained in order to form the second injected body.

Title: Structural system of the steel-skeleton construction type, in particular for the construction of housing
Inventor: HABERMANN KARL A DIPL ING
IPC: F24J2/00
Filed: 1987-06-27
Abstract: In order to utilise the steel-skeleton construction method, in terms of short construction times and cost advantages, for the construction of housing, schools and administrative buildings and to combine it with a solid construction method without lengthening the construction time and producing drying-out problems, the invention proposes a structural system, in the case of which the load-bearing elements for the steel skeleton comprises lightweight steel profiles 1a, 1b, as exterior-wall supporting profiles, which are fitted together with the aid of welded-on tie plates 1d and, prefabricated, can be easily erected in the necessary lengths. Prefabricated exterior-wall panels 2, 2' consisting of lightweight concrete are placed one upon the other in a mortar-free manner using steel dowels 3 and are secured on the exterior-wall supporting profiles 1 and 8 with the aid of steel spring-like clamps 4 and 7, respectively. Since the exterior-wall panels 2 reach as far as roofing panels, upon which it is possible to walk and which are laid on cantilevered roof trusses of the roof structure, and since the exterior-wall supporting profiles 8 can be used for mounting basic cases for windows and doors, a weatherproof shell is provided after a very short period of construction time, which shell ensures, even in the event of unfavourable weather, that further construction work can be carried out in the interior of the structure. <IMAGE>

Title: Electric motor
Inventor: ELSAESSER DIETER
IPC: H02K29/08
Filed: 1987-10-31
Abstract: According to the invention, the stator of an electric motor has through-openings into which insulating material pegs are inserted. Axial holes (28) which are preferably constructed in the form of funnels pass through the pegs in which the wire ends (44, 45, 46) of the stator winding are guided. The through-openings can also be formed by the intermediate spaces between adjacent winding coils (37-42) on a slotted stator. The wire ends (44, 45, 46) of the winding coils (37-42) are aligned as a result of this measure such that they are straight and are at a defined distance apart, so that installation on a circuit board is simplified, and the risk of damage is reduced. The invention is particularly advantageous in conjunction with the stators which are potted in synthetic resin. <IMAGE>

Title: Neodymium-YAG laser with switchable wavelength
Inventor: THYZEL REINHARDT
IPC: H01S3/106
Filed: 1988-04-20
Abstract: The invention relates to a neodymium-YAG laser having a laser medium arranged between two mirrors, the emission wavelength of which can be switched over between 1064 nm and 1320 nm. The laser according to the invention is characterised by the combination of the following features:   - both mirrors are arranged fixed and have a high reflecting power for both emission wavelengths, so that only the one emission wavelength can be stimulated in the ground state, - in order to switch over to the other emission wavelength, an additional element can be interposed in the optical path between the laser medium and one of the mirrors, which element reduces the reflecting power of the entire system for one of the wavelengths to a value such that the resonance condition for this wavelength is no longer satisfied, and leaves the reflecting power of the entire system for the other emission wavelength practically unaltered, so that the resonance condition for this wavelength is satisfied.
