Title: Chair or armchair with synchronously adjustable inclination of backrest and seat
Inventor: NIKOV LJUBOMIR
IPC: A47C1/032
Filed: 1987-10-17
Abstract: Swivel chairs with a lever mechanism which supports the seat and the backrest and synchronously adjusts their inclination are known, in particular; however, the movement sequence has so far not been coordinated such that on pivoting back the backrest a relative movement between the user's back and the backrest, which pulls the upper-body clothing upwards, is avoided; furthermore, the front seat part tilts up and down at the same time and alters the position of the legs and their distance from the floor. According to the invention, a chair maintains inclination and height level of the front seat part (8) in every adjustment position and keeps a constant distance between two points (17, 18) in a region, in each case a broad central region, of seat and backrest (2). This is achieved by an articulated seat shell with front part (8), articulation (10) and rear part (9); by a rear support (4) which supports and pivots the seat part (9) and the backrest (2) and is pivotable about a fixed shaft (7) on the front, immovable support (3) within a pivoting sector defined at the bottom by the horizontal; and by a lever arrangement (11, 12) on the support (3), which lever arrangement supports the front seat part (8) and allows the seat part (8) to move only horizontally during the pivoting and inclination movement of backrest (2) and seat part (9). <IMAGE>

Patent DE-3810826-A1 (DE)
Title: Solenoid injection valve for internal combustion engines
Inventor: THOENNESSEN DIETER
IPC: H01F7/16
Filed: 1988-03-30
Abstract: Injection valves are known, in which the stop surfaces between armature and magnet have been provided with a nickel coating. The application of this nickel coating is very expensive and the thickness of the coating can be produced only with large tolerances, so that the air gap between the bearing surfaces (in relation to the magnetic circuit) varies greatly. By contrast, the characteristic feature of the new valve is that at least one of the stop surfaces of the round rod or the valve closing body is of calotte shell (spherical) design and has a circular body insert of antimagnetic, high-strength material in the middle of the stop surface. The new valve is characterised by extremely low susceptibility to wear and controlled magnetic effect and is suitable for internal combustion engines. <IMAGE>
Patent DE-3815605-A1 (DE)
Title: Use of additive mixtures as a means for increasing the vaporisation rate and combustion rate and the combustion stability of liquid propellants and fuels injected into rocket combustion chambers or high-output combustion installations
Inventor: BSCHORR OSKAR DR RER NAT
IPC: C06B23/00
Filed: 1988-05-06
Abstract: Additive mixtures, which consist of a) organic compounds with highly conjugated  pi -bond systems and longwave main absorption bands in the wavelength range from about 350 to 1200 nm, b) organic surface-active substances and c) organic solvents and suspending agents for the components a and b, are used as means for increasing the vaporisation rate and combustion rate and also the combustion stabilities of liquid propellants or fuels and oxidisers for rocket engines or other high-output combustion installations which are likewise operated with liquid fuels and in which combustion problems comparable with rocket engines arise due to energy transfer disturbances. The additive mixtures are injected together with the propellents or fuels and the oxidisers with uniform, geometrically optimised distribution, which is as symmetrical as possible, according to defined economical methods into the combustion chamber. Highly conjugated  pi -bond systems effect, because of their property of exchanging radiant energy, in combination with surface-active substances, more rapid and more uniform activations of larger proportions of molecules taking part in the combustion up to the stage of the state ready for reaction, which is synonymous with increased stabilisation of the combustion process.
Patent DE-3827350-A1 (DE)
Title: Pneumatic relay valve
Inventor: SIEBOLD MANFRED
IPC: B60T15/24
Filed: 1988-08-12
Abstract: A pneumatic relay valve, in particular a trailer control valve for a dual-circuit pneumatic brake system in tractor vehicles, has an inlet, outlet and vent chamber (14, 15) with inlet and outlet valves (17, 20) arranged in between which are actuated by a control piston (21). The control piston (21) defines the outlet chamber (15) on the one side and a control chamber (16) on the other side, in which a control pressure, in particular the operating brake pressure, is admitted. The control piston (21) assumes a centre or equilibrium position in which the pressure selected in the outlet chamber (15) is constant and assumes a value dependent upon the pressure admitted in the control chamber (16). In this centre position of the control piston (21), the inlet and outlet valves (17, 20) are closed. For the purpose of avoiding a droning noise which develops during rapid braking as a result of the vibration of the control piston (21) in its centre position, a choke (43) is provided in the outlet valve (20). The choke (43) is arranged and designed in such a way that it is effective only in the centre position of the control piston (21) and is neutralised again during the full outlet stroke of the control piston (21) (Fig. 1). <IMAGE>
