Patent DE-3342377-A1 (DE)
Title: Liquid propellant
Inventor: REINELT KARLHEINZ
IPC: C06B47/00
Filed: 1983-11-24
Abstract: For generating propellant gases in propellant combustion chambers of tube weapons, liquid propellants are to be provided with which, in addition to complete conversion, a gas pressure curve can be realised which, in the burn-off rate, is adapted to the burn-off time corresponding to the particular requirements specific to the weapon and projectile and is very largely oscillation-free and plateau-like.   According to the invention, this object is achieved by a monergolic or non-hypergolic liquid propellant which contains up to 40 per cent by weight of additives which modify the burn-off characteristics, preferably inhibitors. The starting materials used are aliphatic compounds, preferably nitrated alkanes or nitrates of the alkanes, for example isopropyl nitrate or nitromethane. For moderating the burn-off, alcohols, for example methyl alcohol or isopropyl alcohol, are mixed as inhibitors with the starting material. The inhibitors and/or liquid propellants contain further additives which, as free-radical scavengers, very largely prevent the gas pressure oscillation and can produce a plateau-like gas pressure curve 4,5. By varying the starting material, the inhibitors and the additives of the inhibitors and/or liquid propellants, gas pressure curves can be obtained which are very largely oscillation-free but can be varied in the burn-off characteristics, in particular in burn-off time and in pressure level. <IMAGE>

Title: Traction machine which can be used in agriculture and which has a coupled working appliance
Inventor: GOEHLICH HORST PROF DR ING
IPC: A01B63/111
Filed: 1984-12-21
Abstract: What is proposed is a tractor (10) with an articulated plough (12), in which the electrohydraulic lifting-unit control device (18) works as an active system for vibration damping on transport trips. Changes of force which occur as a result of pitch vibrations are measured by sensors (25, 27, 28) working as a function of force and the working appliance (12) is adjusted relative to the tractor (10) as a function of this, in such a way that vibrations are cancelled. Dynamic wheel loads resulting from the vibrations can no longer nullify the static front-axle load, so that, even at high transport speeds and with heavy ploughs, sufficient road contact and therefore steering safety are guaranteed.

Title: Folding door for rail vehicles
Inventor: BRANDENBURG RUDOLF
IPC: B61D19/02
Filed: 1984-12-24
Abstract: The invention relates to a folding door for rail vehicles with a step which is located behind the plane of the body of the vehicle and, in order to save space, is located in the swivel area of the sub-leaves of the door. It was known to provide recesses in the sub-leaves and to close the openings by flaps which are pushed up by the step. Since these flaps are liable to faults, the object of the invention is to simplify their function and to reduce the maintenance requirements. The object is achieved in that each closure flap is connected at its left end and right end to the sub-leaves via hinges, in that the closure flap is elastically deformable in its central region, in that the two halves of the flap enclose an obtuse angle when the door is closed and in that the halves of the flap form a parallelogram with the sub-leaves when the door is opened. <IMAGE>

Abstract: The invention relates to a cleaning apparatus for a filter press, in which a spray tube which can travel in the longitudinal and transverse direction of the filter press can be pivoted, for spray cleaning the filter plates with a cleaning liquid, between an idle position above the filter plates and a downwards-swung working position between opposite filter plates spaced apart from each other. A pivot arm, which in the idle position is directed upwards and in the working position is directed essentially vertically downwards, is arranged on a rotating shaft in a rotationally solid manner, to which pivot arm a pivot rod which carries the spray tube is pivotably linked about a parallel rotating axle, which is spaced apart from the rotating shaft. A stopping element blocks the pivoting of the pivot rod and the spray tube beyond the operating position. The pivot arm, in the vicinity of the rotating axle, carries a mounting lug which lies against the pivot rod only in the operating position and restricts this between the lug and the stopping element.

Abstract: The front panel of the door station of a domestic telephone system with a grille encasing the loudspeaker of this door station and with passage holes to accommodate fixing screws and to attach the front panel is intended, in order to prevent unauthorised removal of the front panel and destruction or theft of parts of the door station, to be designed in such a way that the heads of the fixing screws retaining the front panel are removed from view and access by persons unfamiliar with the device. For this purpose, the fixing holes 9 are provided on the base of grooves 6 into the clear space of which strips 11, 12 provided on the upper periphery of the edges of the groove engage. Covering strips 14 can thus be inserted into these grooves whose peripheral areas 16, 17 are covered by the strips in such a way that, although they can be inserted from one side, they are held in such a way that they completely cover the heads of the inserted fixing screws. The surface of the covering strip is provided with rods 15 whose shape and arrangement correspond to the rods of the grille covering the loudspeaker and seem to form a part of the fixed grille. On the other hand it is relatively simple for persons familiar with the device to insert the covering strip, appropriately with a double movement, an initial pivoting movement followed by a bolting movement effected as a transverse shift, or to remove it for any required inspections or repairs, while the ...
