Patent DE-3544233-A1 (DE)
Title: Exhaust port geometry for two-stroke trunk piston internal combustion engines
Inventor: DIENST MICHAEL
IPC: F02F1/22
Filed: 1985-12-12
Abstract: When the exhaust port of a two-stroke engine opens, the sound waves excited by the pressure gradients existing between cylinder charge and surroundings make a significant contribution to the total noise emission of the engine due to abrupt opening of the exhaust port. The invention is based on the assumption that milled recesses in the inner wall of the cylinder above the exhaust port will permit a certain proportion of the working gas to transfer into the exhaust pipe in a phase preceding the port opening, thereby reducing the temporary pressure gradient of the gas in the exhaust pipe. The parallel milled recesses are freed by the working piston either simultaneously or in succession, depending on the design; for thermal relief of the piston skirt the milled recesses are designed inclined towards the cylinder vertical axis. Subsequent refitting is possible, it being necessary to adapt the length, width and depth of the milled recesses and the angle of inclination to the special requirements of the particular engine.

Title: Process and apparatus for forming a firm fabric edge
Inventor: MEIER ERICH
IPC: D03D47/50
Filed: 1986-03-15
Abstract: A process for forming a firm fabric edge (selvedge), in particular a border and/or separating edge, from a base fabric composed of acrylic, polyester, cotton or the like, is carried out by subjecting the fabric edge to the action of heat. In the region of the fabric edge some warp threads of the material of the base fabric are replaced by warp threads consisting of or comprising a plastic whose melting point is below the decomposition temperature of the material of the base fabric. The warp threads consisting of or comprising the plastic are heated into approximately the plastification region and bonded together by means of pressure and cooling time to form a firm strip which binds in the weft threads. In the region of this strip the formation of the fabric edge is effected by a mechanical separating process. <IMAGE>

Title: Process and equipment for producing cement clinker
Inventor: HEINEMANN OTTO DIPL ING
IPC: C04B7/40
Filed: 1986-10-02
Abstract: The invention relates to the production of cement clinker from cement raw meal, which is first preheated in a cyclone preheater, then calcined in a calciner, fired in a kiln to give cement clinker and finally cooled by means of cooling air in a clinker cooler. In this production of cement clinker, the largely calcined cement raw meal coming from the calciner is intercooled and then bricketted, before it is charged in the form of uniform brickettes in the kiln. This allows a process sequence with relatively small heat requirement and relatively low NOx emission.

Patent DE-3641177-A1 (DE)
Title: Apparatus for the production of yarn or twine
Inventor: SCHUMANN KLAUS
IPC: D01H1/11
Filed: 1986-12-02
Abstract: The invention relates to an apparatus for the production of yarn or twine, consisting of at least three rotationally symmetrical bodies which are rotatable and the outer surfaces of which are arranged close to one another, and in which the formation of the yarn or twine takes place as a result of the twisting together of the constituents of the yarn or twine between the rotationally symmetrical bodies. The object on which it is based is to allow the reliable working of the apparatus, to avoid production failures and to lower the outlay for driving the rotationally symmetrical bodies. The object is achieved in that the rotationally symmetrical bodies (1) are mounted in a supporting body (2) driven by means of pulling-means mechanisms having a rotating pulling means (3) and are surrounded by a stationary guide body (5, 15) of circular inner cross-section, there being contact between the inner surface (8) of the guide body (5, 15) and the rotationally symmetrical bodies (1) - Figure 1 -. The invention achieves the technical effect that, when at least three rotationally symmetrical bodies are arranged, their axes are reliably maintained parallel or in another predetermined position to one another, this position is preserved even at high rotational speeds and at least three rotationally symmetrical bodies are driven jointly. <IMAGE>
Patent DE-3642601-A1 (DE)
Title: Haymaking machine
Inventor: LESSLHUMER JOSEF ING
IPC: A01D87/10
Filed: 1986-12-12
Abstract: Because material is transported pneumatically in a cross-conveying gutter open at the top, in conventional haymaking machines the transfer of material from the pick-up drum to the pneumatic cross-conveyor and the material conveyance of the latter are inadequate, involve high losses due to crumbling and are suitable only for haymaking machines of narrow construction. The new haymaking machine is to improve the transfer and conveyance of material even over relatively long stretches and to allow a more careful handling of the material. This is achieved in that the pneumatic conveyor is designed as a fluidised-bed conveyor with a conveying floor having air-outlet slits pointing obliquely relative to the plane of the conveying floor and intended for the outlet of air for the generation of a fluidised bed, and the conveying floor is arranged so far below the vertex region of the pick-up drum that the overflow of the material from the pick-up drum into the air flow of the fluidised-bed cross-conveyor takes place in a region of the said air flow having a low flow velocity. The new haymaking machine is suitable for the rapid and careful pick-up of hay from the ground and for depositing it in a swathe or in broadcast form and can be equipped, in particular, with pick-up drums of wide construction and pneumatic cross-conveyors.
Patent DE-3643064-A1 (DE)
Title: Device for locking hoists, lifts and the like
Inventor: TRONICKE FRIEDRICH
IPC: B66D5/26
Filed: 1986-12-17
Abstract: Known locking mechanisms taking the form of double clutches are operated mechanically, with the clutches being released and engaged via a lever arrangement. These double clutches have the disadvantage of not being adjustable, because of the friction-caused wear on the clutches and on the lever linkage, and of the transmittable driving torque not being controllable, but rather given by the lever geometry. In addition, such double clutches have a large overall length. A double clutch with hydraulically operated clutches (7, 8) automatically re-adjusts the clutch play due to friction, and has the advantage that the driving torque to be transmitted by the driving clutch (8) is controllable, since the piston's (15) force of pressure depends on the pressure of the hydraulic fluid. In addition, such double clutches have a small overall length. Locking mechanisms of this kind are preferred for use in hoists, lifts and the like, in order to prevent the load sinking if the driving torque no longer acts.
Patent DE-3702321-A1 (DE)
Title: Cable junction terminal
IPC: H01R11/20
Filed: 1987-01-27
Abstract: The invention "cable junction terminal" makes it possible to connect a branch conductor to a main cable conductor which is to be made contact with when live, said main cable conductor being fixed in a retaining space in the terminal, in the region of the junction, without interrupting said main cable or the voltage supply. A cutting screw can be guided in the said retaining space in order to penetrate the insulation of the main conductor, which cutting screw produces the electrical connection between the two conductors via a contact part to the clamping channel of the branch conductor. In contrast to known single-phase electrical junction terminals, the present junction terminal relates to a single-phase junction terminal which is essentially completely electrically insulated from the exterior. The clamping channel of the branch conductor end is fitted in a lateral elongation of the contact part, the contact part being guided in an electrically insulating plastic housing and it being possible to push the ends of a part which is in the form of a bracket (clip) and consists of electrically insulated plastic on at the sides thereof, as a result of which the retaining space is formed in order to make contact with the main cable conductor. The junction terminal has an extremely compact structural form. The junction terminals can be arranged in an extremely confined space in order to make contact with a multi-phase main conductor.
