Patent DE-3738818-A1 (DE)
Title: Method of producing a yielding body of construction material
Inventor: KETTERER KLAUS DIPL ING
IPC: C04B20/00
Filed: 1987-11-16
Abstract: Construction material used in underground mining and tunnelling in fabric cushions or tubes (formwork reinforcement) but also in other formwork can perform its supporting and sealing function for a prolonged period if hollow bodies are put with the setting construction material into the fabric envelopes. The hollow bodies are made of a material rupturing under pressure and are distributed as uniformly as possible in the entire body of construction material. These hollow bodies have a wall which as far as possible forms a connection with the surrounding construction material so that the hollow bodies do not act as foreign bodies but on the contrary can form a harmonic bond with the construction material. If pressure occurs on the body of construction material, the wall of the hollow bodies ruptures so that, for the construction material which has come under pressure and ruptures in the process whether one likes it or not, hollow spaces are predetermined into which the construction material can penetrate without breaking away to the outside or loading or overloading the surrounding fabric envelope (formwork reinforcement). <IMAGE>
Patent DE-3743314-A1 (DE)
Title: Filling device
Inventor: HEINZ WILHELM DIPL ING
IPC: F16N37/00
Filed: 1987-12-21
Abstract: The filling device is provided with lubricating grease for the metered filling of ball bearings which are sealed off on one side, such as the drive shafts of cars. It is very often a requirement that the edge zones of the filling side (3) Figure 1 must remain free of grease, because sealing compounds for sealing caps are subsequently to be applied. There is also a requirement for every shaft (1) to remain free of grease Figure 1. The filling device is brought, with open shaped jaws (5a) and (5b) Figure 1, via the tapping articulation to the drive shaft and/or the drive shaft is interposed. Then the shaped jaws are closed and the drive shaft is pulled on the shaft in such a way that it is jerked through its path of displacement and is in fixed contact ready for greasing Figure 1. The soft underside of the shaped jaws causes the annular supporting surface (3) Figure 1 to be fully covered. The shaft (1) Figure 1 is fixedly enclosed in an annular fashion. Introduction of a metered filling quantity causes lubricant, via a connection (7) Figure 1 and the filling channel (17) Figure 1, to pass through the gaps between the ball bearing cage (2) Figure 1 and the balls (4) Figure 1 into the filling chamber base (19) Figure 1. The air displaced from the chamber can escape via channels in the other shaped jaws. <IMAGE>

Owing to this shape of the slot, interlocking parallel webs are formed from both sides which, during tensioning, slide laterally upon one another. At the free ends of the webs, the slots are widened in the circumferential direction in such a way, that the tensioning movement is not impeded. The webs preferably run over approximately 1/3 of the circumference of the tension clamp. The free ends of the webs are passed from outside through the tensioning bar situated opposite.
Patent DE-3802676-A1 (DE)
Title: Railway superstructure
IPC: E01B3/00
Filed: 1988-01-27
Abstract: For a railway superstructure consisting of a solid supporting layer and arranged on top of this a track grid consisting of sleepers and rails, it is proposed to arrange between the surface of the solid supporting layer and underside of the sleepers a soft, elastomeric, gas-filled compensating film which does not adhere to the supporting layer. In the case of a rough surface, the bearing area of the sleepers is thus enlarged, and at the same time the sleeper is mounted in an oscillation- and noise-damping manner. Corrections of track position are possible without destroying the hitherto customary bitumen/asphalt/adhesive material; the track grid may be installed even in wet weather and frost. The track grid may be fixed in position by means of positive anchoring.

The connection points of the storage element are sealed alternately unilaterally by a movable sealing element which can be formed by a ball or a piston. The sealing element can also be formed by a damping drum having a number of parallel running damping hoses or damping pipes, the damping hoses or damping pipes having cross-sections of different size. The damping drum is assigned in each case an end-side cover plate with an annular duct and on one side a rotatable nozzle plate provided with bores of different size.
Patent DE-3808797-A1 (DE)
IPC: B23G5/18
Filed: 1988-03-16
Abstract: In a thread milling cutter comprising at its tip cutting edges for making a bore, said cutting edges are formed as face milling cutting edges which enclose a mutual angle of 180 DEG  or more, so that the thread milling cutter on reaching the intended drill hole depth and in order to be laterally moved need not first be raised. Also, it is possible with the thread milling cutter according to the invention when using said cutter to make threads of any desired diameter with the same thread pitch because the tool tip does not run against the drill hole bottom when laterally moved or offset as with the known thread milling cutter. In addition it is possible with the same tool to provide the thread at the entry with an edge-chamfer in such a manner that impairment thereof by formation of burrs is impossible.

Patent DE-3823956-A1 (DE)
Inventor: KOHLMANN HANS-ALBRECHT
IPC: F23D14/02
Filed: 1988-07-12
Abstract: A gas burner has at least one burner rod (6), the wall of which is passed through on the upper side by outlet openings (2) for a gas mixture consisting of combustion gas and primary air. The region situated above these mixture outlet openings (2) is assigned guides (5), via which a mixture consisting of gas and secondary air or pure gas is supplied to the flames being formed above the outlet openings (2). The guides (5) can be formed by the outlet openings (8) of mixture or gas distributors (7) which run parallel next to the burner rod (6). Such distributors (7) can be interconnected by connection pipes (9) which run transversely to the axis of the burner rod (6) and which have outlet openings for the gas/secondary air mixture. Such a distributor (7) can also, however, partially enclose the burner rod (6), leaving the top region (12) with the mixture outlet openings (2) free and forming at the two boundaries of this top region outlet openings for the gas/secondary air mixture or other gases such as e.g. recycled smoke gas. <IMAGE>
Patent DE-3824834-A1 (DE)
Inventor: BERGMANN KARL-HEINZ DIPL ING

Filed: 1988-07-21
Abstract: The cleaning device for the piping system (3) of a whirlpool bath (1), which piping system contains a circulation pump (2), comprises at least one suction opening (5) provided in the bath wall (6) and, likewise formed in the bath wall, output valves (8) connected to a pressure line and in each case having a nozzle for the supply of a water/air mixture to the inside of the bath. The latter is in communication with a discharge line (11) via a closable discharge opening (9) in the bath bottom (10). Each outlet valve (8) has a valve housing (22), an approximately cylindrical nozzle body (25) which delimits the nozzle channel (24) and is mounted in the valve housing by way of an external thread (40) and can thus be axially displaced by means of torsion, and an air-supply channel (23) which opens into an annular chamber (27) directly adjoining the input side of the nozzle body (25). A central nozzle core (26) is also provided which, when it bears on a valve seat (34) allocated to it, closes the valve and which, by relative axial displacement in relation to the seat, to a greater or lesser extent frees the outlet cross-section for the water/air mixture. A particularly effective and reliable cleaning is ensured in a simple manner by virtue of the fact that the nozzle core (26) is connected to a membrane (31) controlling it; this membrane is constantly acted upon in the direction of closure and delimits a first valve housing space (36) situated on the side remote from the nozzle core (26), which valve housing space (36) is connected to the pressure line (7, 28) by a first solenoid valve (13) or the like determining the duration of the closure state of the outlet valve (8). Disinfectant can be supplied to the suction line (4) by way of a metering valve (16). Provided between the pressure line (7) passing over all the outlet valves (8) and the discharge line (11) is a run-off line (16) with an interposed second solenoid valve (17) or the like, whose opening time is longer than that of the metering valve (16). <IMAGE>

Title: Spin-stabilised bomblet cluster munition (carrier projectile) having an attachment which supports the bomblet columns
Inventor: ALTENAU ERNST-WILHELM DIPL ING
IPC: F42B12/62
Filed: 1988-12-13
Abstract: In the case of previously known spin-stabilised bomblet cluster munitions (10), the lowest bomblets (12) lying side-by-side of the bomblets (12) (which are accommodated as the payload and are stacked one above the other like columns) contain an individual tubular attachment (24) as fuze protection. In order in addition to make this attachment usable during ejection in order to avoid brief radial deflection of the bomblet columns (14), which are arranged side-by-side in the cluster munition (10), as well, and in consequence to prevent damage to the fuzes directly during ejection, all the fuze protection attachments (24) which are arranged side-by-side are non-detachably connected to one another to form a bundle (26). In consequence, during the ejection process, the release process of the bomblets (12) from one another in the radial direction is extended and the kinking or bending process of the bomblets (12) which are plugged to one another is considerably limited directly during ejection, as a result of which, at the same time, the shear forces which originate from each ejected bomblet (12), act on a fuze (22) of the next bomblet (12) and cause damage to them are avoided. The bundle (26) can be produced with a light structure as a welded part or as a cast part, and requires no additional parts, as a result of which loss of space within the cluster munition (10) is avoided. <IMAGE>
