Title: Industrial truck for the transport of pressure-resistant objects
Inventor: STUETTGEN WILHELM
IPC: B66F9/18
Filed: 1988-01-19
Abstract: Objects of this type such as, for example, blocks for building purposes normally have to be stacked on pallets which are gripped fork-like from underneath and conveyed by a transporter. However, pallet operation is very expensive. In addition, there is a transport hazard on account of the usually unstable centre of gravity of the objects to be transported. The invention removes these difficulties owing to the fact that a U-shaped chassis frame with vertical frames is provided, between which at least one liftable gripper with movable gripper legs extending downwards is mounted, the distance apart of which legs is wider than the object to be transported so that, by actuation of the grippers, the object can be lifted directly from the ground and can then be transported with the chassis of the transporter.

Title: Variable-load valve for airbrakes of vehicles
Inventor: WOSEGIEN BERND DIPL ING
IPC: B60T8/18
Filed: 1988-02-15
Abstract: The variable-load valve for airbrakes, especially of rail vehicles, has a cam (5), rotatable as a function of the load, the cam surface (7) of which is composed of a run-on face (8) and a roll-off face (9). A roller (12) of a rocker lever (13) is capable of rolling on the cam surface (7), the roller (15) on the other side of which lever is capable of rolling on the end face (16) of a valve tappet (17). The axially displaceable valve tappet (17) belongs to a valve device (22) for controlling a pressure representing a load-dependent signal.   Movements caused by ride shocks lead at most to rolling of the roller (12) on the roll-off face (9), the rocker lever (13), the valve tappet (17) and the valve device (22) thereby remaining undisturbed. The empty and load changeover valve therefore presents very little wear and can ensure long operating times with little maintenance. <IMAGE>

Title: Device and method for introducing equally spaced and non-slip folds into net curtains and curtains, and also for the fixed and displaceable hanging of the same
Inventor: FRINGS MANFRED DIPL ING
IPC: A47H13/14
Filed: 1988-07-05
Abstract: Net curtains and curtains have, until now, been hung loosely and unstably, in a pre-gathered or ungathered manner, by means of individual loops on simple holding clips or hooks, which also guarantee the movement of the net curtains. The tensile load during the movement of the net curtains causes the holding clips or hooks to slip as a result of slippage of the pull tapes, and the uniformity of the gathering and of the fall of the folds is no longer present. Holding clips with 3 and more individually loadable loop supports, such as clip legs or hooks (a, b, c, d), permit the fastening of 3 and more net-curtain loops (S2, S4, S6, S8) in 1 hanging point (A) at equal selectable spacings. A net curtain held in this way is also dimensionally stable when subjected to tensile load for opening or closing. The fold which forms at one point as a result of the gathering does not change in shape and position (distance to the next fold). Hanging of net curtains and curtains with ordered folds. <IMAGE>

Title: Redundant integrated navigation method for freely navigating vehicles in the industrial field
Inventor: HIPP JOHANN DIPL PHYS
IPC: G05D1/02
Filed: 1989-04-05
Abstract: An integrated navigation system is a precondition for free navigation. Two integrated navigation systems are provided. When the data from the respective integrated navigation system are used is determined from higher criteria. The first integrated navigation system uses the output signals from angle encoders for calculating the position. This integrated navigation system is subject especially to fault influences over the travel path. The second integrated navigation system uses a gyroscope for angle measurement and angle encoders only for distance measurement. It is calculated whether the position calculated only by means of angle encoder data or the position calculated by means of angle encoder data and gyroscope data permit a smaller error to be expected. The respective expected better position is used for calculating correction values for the current position for the vehicle control on a desired course stored in the vehicle. For both integrated navigation systems the vehicle computer monitors whether the allowed operating ranges for the sensors are exceeded. If, in the more accurate gyroscope system, the permissible limits are exceeded, the last position data accepted as still usable are used for updating the first integrated navigation system. This position is continuously progressively calculated and used for navigation until the more accurate gyroscope system is operating once more in the permitted range. Thereafter, this is then updated with the data from the first integrated navigation system and [lacuna] for... Original abstract incomplete.

Title: Recovering pure gas by freezing out solvent vapour - by heat exchange with cryogenic fluid in surrounding jacket
Inventor: REICHSTEIN VOLKMAR DIPL ING
IPC: F17C9/02
Filed: 1989-05-24
Abstract: To recover gas in pure form, free of entrained solvent, gas dissolved in solvent in a storage container (1) is withdrawn into an adjacent vessel (3) contg. heat exchange structures (4). These structures play their part in cooling the entrained solvent by cryogenic fluid circulating in a jacket (6) round the receiving vessel. Suitable cooling fluids include CO2, N2 or Ar in their liq. forms. Cooling is sufficient to condense solvent vapour to collect at the heat exchanger vessel base for removal from a valve controlled outlet (8). The initially dissolved gas is recovered in pure form from an upper outlet (10) contg. a temp. sensor (11) controlling the supply of cryogenic fluid and ensure constant prod. purity, but without condensing the required gas. USE/ADVANTAGE - Esp. for acetylene prodn. e.g. in flame photometry where freedom from solvent is important.

Title: Improving claus reactor output - by adding ammonia to hydrogen sulphide feed gas before initial partial combustion stage
Inventor: MEISL ULRICH DR ING
IPC: C01B17/04
Filed: 1989-06-19
Abstract: Before entering a single- or multi-stage Claus reactor, H2S gas from which sulphur is to be produced undergoes pential combustion. Depending on the amt. of H2S in the feed gas, this combustion takes place in a single furnace or in two furnaces operating in parallel, while further treatment is in a single reactor with output matching the max. expected sulphur flow. Behind the Claus reactor residual gases are catalytically hydrogenised, converting any remaining 5 cpds. to H2S. To ensure adequate presence of H2 for hydrogenisation, the initial feed gas is admixed with ammoniacal waste gas before the combustion stage. Such waste gas may derive from any source, and the amt. added may reach equality with the feed gas. ADVANTAGE - Process economies are improved, and total discharge of NH3 into atmos. may be reduced.
