Patent EP-0296305-A2 (EP)
Inventor: RAHNENFUHRER ECKHARD
IPC: F42B5/18
Filed: 1988-01-21
Abstract: The invention relates to cartridge ammunition with a combustible case for machine guns, especially for automatic weapons with high firing rates. 
<??>Ammunition for automatic weapons is exposed to high loads, such as impact, bending, tensile and compressive stresses, when being fed into the weapon. It must also be possible for these loads to be withstood reliably by cartridges with a combustible case, which are substantially more sensitive than ammunition with a metal case, in order for example, to prevent the projectile from breaking out of the case and associated faults in the weapon functioning. 
<??>Known ammunition of this type has a plurality of threaded auxiliary elements, such as a conical neck part and a connecting intermediate ring between the projectile and case, and is cost-intensive and involves a high outlay in terms of production. The invention provides a cartridge ammunition which can be produced simply and cost-effectively, the case 12 consisting of three prefabricated and assembled individual parts, namely a front case cover 14, a cylindrical case jacket 15 and a rear case bottom 16 which are glued firmly to one another in their annular regions of contact.

IPC: C09K11/76
Filed: 1988-01-29
Abstract: A method for eliminating carbonaceous contaminants and preventing the hydration/solubilization of the oxide coating of a phosphor is described. The method involves the annealing of the oxide coated phosphor at a tempera­ture and for a period sufficient to preclude adversely affecting the protective oxide coating on the phosphor during subsequent water-based suspension processing without detrimentally altering the phosphor. After annealing the phosphor is cooled and then added to a water-based suspension. The optimum conditions for annealing a manganese activated zinc silicate phosphor or a calcium halophosphate phosphor having a protective aluminum oxide coating are the combination of a tempera­ture between about 700°C and about 850°C and for a period of time from about 15 minutes to about 20 hours.

IPC: B01F25/74
Filed: 1988-07-15
Abstract: Conventional plaster mixers, in which the mixing is carried out by a rotor disc having pins, require a high level of maintenance. Dihydrate particles, and possibly chips and fibres, accumulate in the blind areas downstream of the pins on the rotor disc, and under the rotor disc, resulting in blocking of the rotor disc and impairing the quality of the plaster boards. The invention is intended to reduce the level of maintenance. 
<??>Some of the mixing water flows outwards, from a meterable water feed (15) between the housing bottom (13) and the rotor disc (3), through an annular constriction (17), so that the rotor disc (3) is floatingly mounted. A continuous film of water, on which the plaster powder falls, is produced on the smooth rotor disc (3) by means of water inlets (19) distributed in a ring in the housing lid (7).

Abstract: To centre optical lenses for mechanical clamping, especially during bevelling and facetting, a device is used which has a housing (10) in which a split drive shaft (14, 14') with a torque divider (50) is mounted. Two centring spindles (18, 18') in alignment in the axial direction (A) are thereby motor-driven. The spindle ends facing one another carry bell-shaped clamping elements (20, 20') between which a lens (L) can be orientated and clamped. There is an air bearing at least for the lower clamping spindle. Compressed air can be admitted to the air bearing via axially parallel and/or index-ring-shaped passages (90) with control ports (A, B). In particular, pressure can be applied to two diametrically opposite air-cushion zones. The clamping spindle (18) is then axially movable in a free-running manner, in the course of which a diaphragm piston (32) permits infeed proportioned in very fine steps. …<IMAGE>…

Abstract: A light absorption analyser can work in either a reflection or a transmission mode, according to which probe head is fitted to it. 
     Light is caused to be of a desired wavelength for the analysis by passing non-monochromatic light from a high-intensity flash tube source (10) (which is not a point source) to an interference filter (13). Only parallel light emanating from the filter (13) is focused by a concave parabolic mirror (21) on a point where at least one fibre-optic collector (14,22) is positioned. This light can then be passed directly to the probe for passage through the sample, since it is only light of a specified wavelength which will have travelled parallel from the filter and will therefore be focused at the point. Some of the light is taken off a reference detector (17) to provide a reference signal for comparison with that derived from a test detector (20) fed by a return fibre-optic (19) from the probe. A comparator (18) is programmed to give a quantitative readout of the absorption by the test sample.

Abstract: A glazing alarm consists of a pane of toughened glass (28) and a device which when the glass pane (28) is broken sends an electrical pulse. The device that sends the electrical pulse comprises a physical support (a housing 26) joined to the glass pane (28) and a spring under elastic deformation (a helical spring 39). When compressed, one end of the spring (39) bears against the end (31) of the housing (26) and the other end through an intermediate pusher (37) against the surface of the pane of glass (28). When the pane of glass (28) is broken, the spring (39) expands owing to the disappearance of the fragments of glass. The physical contact between the contacts (34, 37) is consequently interrupted, triggering the signal setting off the alarm. <IMAGE>

Abstract: The invention relates to a construction machine for applying a new covering to bicycle tracks, footpaths or the like. A construction machine of this type consists of a chassis (42) having a drive motor (5) and a bunker (5), arranged on the chassis, for the covering material, which is drawn off against the travelling direction via a conveyor belt (6) and is discharged in front of a tamping beam (7). Construction machines of this type are also used to repair existing old coverings, for example for closing the covering again after carrying out work on the sewers. To this end, however, manual preliminary work has to be carried out, such as, for example, cleaning of the edges and the like, which is very time-consuming and involves a lot of labour. According to the invention, provision is made for arranging a milling and mixing device (8) between the conveyor belt (6) and the tamping beam (7), which milling and mixing device (8) mills off the old covering to a predetermined width, mixes the milled-off old material with new covering material and discharges it in front of the tamping beam (7) which places the mixture as new covering. Manual preliminary work can therefore be dispensed with. <IMAGE>
