Title: Hydraulic system with pressure accumulator - has accumulator diaphragm actuating valve connecting to pump or equipment served
Inventor: FARR GLYN PHILLIP REGINALD
IPC: F15B1/02
Filed: 1980-11-07
Abstract: The hydraulic system has a pump delivering fluid from a tank to an accumulator under pressure. A valve between pump and accumulator prevents overfilling of the latter and allows the pump to top it up when its pressure falls below a min. value, and contains a control valve, whose plug in one position cuts the accumulator off from the equipment serves to allow the pump to recharge it, while in the other it connects accumulator to equipment and unloads the pump. The diaphragm (26) in the accumulator (22), separating the fluid chamber from one containing compressed gas, works with the valve plug (30), providing the power to move the latter between its two positions.

Title: Vertically adjustable board, in particular camp bed
Inventor: WOLFF ERWIN
IPC: A47C19/04
Filed: 1982-02-13
Abstract: A vertically adjustable board, preferably a camp bed, a bed, a table or the like, is held at two mutually opposite sides in each case by three parallel and pivotable bearing arms. The attachment points of one of the bearing arms are offset in height, preferably upwards, relative to those of the other bearing arms when the board is arranged horizontally. In this case, all three bearing arms are of equal length and the central bearing arm is preferably offset in height relative to the two adjacent outer bearing arms. This results in a secure fastening during the pivoting of the board from one end position into the other, even in the position in which all the bearing arms run parallel to the board. Special guides with the aid of stabilisers, slots or the like, which would not have enough room, for example inside vehicles, are avoided.

Title: Process for removing sulphur oxides from the combined waste gases of FCC plants and the associated selective vaporisation plants
Inventor: BARTHOLIC DAVID B
IPC: C10G11/18
Filed: 1982-03-31
Abstract: A system is made available, by means of which the sulphur oxide content in emissions, which pass into the atmosphere in the combined waste gases from the selective vaporisation and, in fluid catalytic cracking, of the improved charge material resulting in the selective vaporisation, can be controlled. The invention leads to a reduction in the sulphur oxide content of the waste gases from the FCC regenerator and the burner for the selective vaporisation, and a new controllable variable for a heat-balanced FCC unit is provided. The cracking catalyst used is capable of reversibly reacting with the sulphur oxides in the combined waste gases, in order to recycle the sulphur to the reactor, where it is - at least partially - converted to hydrogen sulphide which is removed from the reaction products in the normal treatment sequence of the cracked products from the reactor. In the system disclosed, the mixture of the waste gases is cooled down and then contacted with the hot regenerated catalyst from the regenerator, in order to induce the sorption of the sulphur oxides by the catalyst and to cool the catalyst down for the purpose of controlling the reaction parameters in the FCC reactor.

Title: Retrofit device for obtaining a 2-stage flushing in conventional WC flushing cisterns
Inventor: SCHLEMMINGER JUERGEN
IPC: E03D1/14
Filed: 1982-07-30
Abstract: According to the invention, for the 2-stage flushing in conventional WC flushing cisterns, a shell (3) which is not closed right round, can be lifted, and stands on the bottom of the flushing cistern, the height of which shell corresponds to only part of the height of the flushing cistern water, is assigned to the water outlet valve, characteristic of each flushing cistern, at a distance therefrom. An element (strap, drawing 1 (10)) attached to the shell connects the valve-actuating element, characteristic of each flushing cistern, in such a way that the shell is lifted upon each valve actuation to initiate flushing. A member, assigned to the shell, with a supporting and/or holding function (drawing 1 (14)) prevents the shell in the lifted state, when the flushing cistern water is flowing out, from descending again as a function of the time of the flushing actuation, so that the entire quantity of flushing cistern water consequently no longer flows out in a manipulable manner. <IMAGE>

Patent DE-3305211-A1 (DE)
Title: Design of track-laying running gear for improving its versatility in use
Inventor: KESSLER PETER
IPC: B62D55/28
Filed: 1983-02-16
Abstract: The object of the invention is to make available a track-laying vehicle which can also be used on extremely difficult terrain and under extreme weather conditions (snow, mud, rubble, etc.). This is achieved by means of very wide tracks which as far as possible take up the entire ground area of the vehicle. The problems with such wide tracks are, inter alia, travelling around bends. However, this is prevented according to the invention by means of the special design of the base plates; here, when travelling over ground which has normal load-bearing properties only part of the special base plates touches the ground. However, if the ground is soft, the part which in the normal case as described above touches the ground sinks in, the entire area of the base plates then rests on the ground and can be used for propulsion. As a result, when required, a very small ground pressure is obtained and the vehicle is prevented from getting stuck on obstacles; otherwise however, the problems which arise as a result of wide tracks are avoided.
