Title: Device for filling open bags
Inventor: MEUWESEN HANS
IPC: B65B39/08
Filed: 1984-07-25
Abstract: The device according to the invention has a hexagonal filling nozzle (1), the distance between the corners situated in the central longitudinal plane being greater than the distance between the surfaces which extend parallel to it and which form the longitudinal sides of the filling nozzle (1). Six clamping jaws (4 to 9) are assigned to the filling nozzle (1), which jaws are designed to be linear and once again describe a hexagon when in the position adjacent to the filling nozzle (1). The bag in between is clamped without deformation, so that no channels are produced through which the filling material or dust particles can escape to the outside. The clamping jaws (6 to 9) which are situated on the end faces of the filling nozzle are designed to be angular, in such a way that the legs form an obtuse angle. The region adjacent to the longitudinal edges of the bag is clamped between the legs, which extend parallel to one another when the jaws are closed, the size of this region depending on the width of the bag (Figure 3).

Patent DE-3431101-A1 (DE)
Title: Hydrofluoric-acid-containing aqueous organic acid mixtures, possibly with an addition of inorganic acids and corrosion inhibitors
Inventor: NEUHAUSEN HUBERT F
IPC: E03B3/15
Filed: 1984-08-24
Abstract: The invention relates to organic acid solutions, characterised in that, instead of hydrochloric acid, they contain hydrofluoric acid, in order by this means to dissolve so-called "mineralisations" and/or other silicic-acid-containing reaction products in drinking water wells, which is not possible with the acid combinations used hitherto. This is associated with the avoidance of a reducing agent or oxidising agent which have previously been required to dissolve manganese oxide (MnO2), in which case it should be noted that, when reducing agents are used, the COD and BOD5 in the reaction waters subsequently pumped out, that is waste waters after regeneration (from wells), is extraordinarily high. When gravel washing machines made of stainless steel are used, pitting corrosion and stress-crack corrosion do not occur, which cannot be avoided when hydrochloric acid is used. There is no problem in neutralising, during well development, any unconsumed hydrofluoric acid via a simple calcium compound (CaO, Ca(OH)2 etc.), absolutely harmless calcium fluoride precipitating out.
Patent DE-3432409-A1 (DE)
Title: Flat air-freight pallet
IPC: B65D88/14
Filed: 1984-09-04
Abstract: The flat air-freight pallet consisting in each case of a flat bottom (1) and an edge strip (2) of an aluminium alloy having holding slots which are open towards the top in the edge strip for the detachable fastening of clamping members, has groove-type depressions (3 or 3a, 3b) which intersect on the underside of the flat bottom, are formed by machining and run parallel to each other in each case. As a result, deformations of the flat bottom during transportation of the pallets on roller bases are prevented, and a more easily formable aluminium alloy can be used for the flat bottoms. This allows a dimensionally stabilising edge construction of the flat bottoms and the integral production of the flat bottoms and their associated edge strips. <IMAGE>

Patent DE-3435296-A1 (DE)
Title: Rotating threaded tube as a drive and for industrial processes
IPC: F04D3/02
Filed: 1984-04-04
Abstract: It is known that the efficiency of an industrial process diminishes, the longer the path from the conversion of an energy into motion to utilising the motion. Generated rotary movement can be utilised directly as the rotary movement is produced, by means of threaded tubes. This is based on the fact that flowing media such as air or water tend to curl inwards, producing suction. If a threaded tube is rotated about its longitudinal axis, water flowing through is forced to wind its way through while curling inwards, and to generate the suction in the process. A suitable drive for this application is the electric internal-rotor motor, if a threaded tube is employed as the axis thereof. This produces, if enough current can be generated by means of generators, the lift and thrust for aeroplanes and helicopters, and as a result runways for landing and takeoff are no longer necessary, because the rotating threaded tubes, which are constructed so as to narrow downwards, compress the air into supporting columns or into driving columns. Railways could float on carpets of air, according to my "floating train" patent application, or aircraft could be flown along current-carrying wires at speeds of approximately 500 km/h from terminus to terminus, from elevated platforms. However, the rotating threaded tube is also suitable for mixing by means of the inwards-curling motion, for example to swirl air and fuel prior to combustion. In the rotating threaded tube, sand and water can ... Original abstract incomplete.
Patent DE-3442289-A1 (DE)
Title: Device for detecting monitored objects, particularly a so-called rail contact for rail vehicles
Inventor: VESPER WOLFGANG DIPL ING
IPC: B61L1/16
Filed: 1984-11-20
Abstract: A device for detecting monitored objects can be used, for example, as rail contact for determining the number of wheels of rail vehicles moving past. To obtain reliable and easy monitoring, it is proposed to use an electrical waveguide fed with a particular radio frequency, which exhibits a complex conductor termination. The conductor termination consists of a resistance and an electrical resonant circuit, the monitored objects to be monitored passing into the active range of the inductive and/or capacitive components of the resonant circuit and acting on these. The radio frequency for feeding the waveguide is in the region of the frequency of resonance of the resonant circuit. Measuring instruments are then connected to the waveguide which respond to the standing waves in it which result from the forward wave generated by the radio frequency and the wave returning at the conductor termination. The measuring instruments output a signal when the resonant circuit is detuned by the monitored objects.

Title: High-speed parallel-bus structure and method of data transmission
Inventor: TETRICK RAYMOND S
IPC: G06F13/374
Filed: 1985-01-05
Abstract: The bus structure comprises both a parallel bus (35) and a series bus (37), which connect to one another data processing units (25, 26) and peripheral devices (30), jointly referred to as "stations", in order to permit the interchange of data and messages at high speed using a minimum of "handshake" events before the actual data transmission. The serial and parallel bus protocols are controlled by message control devices (44, 50), which are coupled to each participating station. A local bus (56) is coupled to processing stations (25, 26) within the system in such a way that access can be made to local memories (54) and secondary processing resources (57) without adversely affecting the data traffic via the parallel bus (35). A direct access by other bus stations to resources (54) coupled to the local bus (56) of one station is likewise controlled by the message control device (44). <IMAGE>

Title: Rotary slide valve
Inventor: WARZECHA FRANK
IPC: F02B1/04
Filed: 1985-04-27
Abstract: Internal combustion engine with at least one combustion chamber, consisting of a rotary slide valve housing with an openly connected housing aperture defined by edges of predetermined position, of drivable rotary slide valves which rotate in the rotary slide valve housing and control the opening and closing of the housing aperture in phase with the working cycle of the internal combustion engine, and of a device for adjusting this phasing during operation. The adjustable, rotating slide valve system according to the present invention can be used to particular advantage in virtually any type of internal combustion engine, including supercharged engines, two-stroke engines and diesel engines. When the system according to the invention is used, each of these engines exhibits an improved fuel utilisation specifically due to the use of an optimum combustion cycle for each engine state. Unwanted exhaust emissions are, moreover, greatly reduced by the adjustable rotary slide valve. A further advantage of the system lies in a reduction of the engine noise. The size of the rotary slide valve results from the radial aperture of the rotary slide valve, from the number of power strokes and from the crankshaft/rotary slide valve speed ratio. <IMAGE>
