Title: Automatic silage feeding line metering - has level monitors on each feeding hopper and weight monitoring of dosing line
Inventor: HEGE ROLF ERICH
IPC: A01K5/02
Filed: 1991-11-12
Abstract: The feeding stations (11 to 14) are each fed from a hopper in which the filling is controlled by a level switch (23). The fodder is prepared in a mixing chamber (1) and fed to the tops of the hoppers by screw feeds. The screw feed drives are on weight sensors and these monitor the amount of fodder taken to fill each hopper. Another monitoring system moves a constant flow of fodder past the hoppers. The time taken to fill each hopper is a measure of the amount of fodder required, and the feeding rate in each pen. A CPU computes the amount of fodder taken from each hopper. ADVANTAGE - Simple automatic feeding, accurate weighing of fodder uptake.

Title: Polyphenylene ether(s)] prodn. - by continuous two=stage oxidative coupling of phenol(s) in a reactor with full back-mixing followed by a reactor with partial back-mixing
Inventor: HEDTMANN-REIN CAROLA DR
IPC: B01J10/00
Filed: 1992-03-25
Abstract: A process is claimed for producing polyphenylene ethers (I) by continuous 2-stage catalytic reaction of oxygen with aromatic mono-hydroxy cpd(s). (II). Stage (1) is carried out in a reactor with largely complete back-mixing, and stage (2) in a reactor with partial back-mixing. Also claimed in an appts. for the process, with 2 reactor (systems) as above. Pref. stage 1 is carried out in a ga/liq. reactor (jet reactor) with a jacket tube which is blanked off at the top and in which one or more downwardly directed liq. jets are mounted at the highest point and fed from a liq. pump circuit, so that a gas phase is entrained with and then completely dispersed in the liq.; before starting the liq. circulation, the static reactor is filled with only enough liq. to leave a gas space at the top of the reactor corresp. to the subsequent hold-up under operating conditions, this gas space is filled with inert gas at pressure pl, and the gaseous reactants are only introduced into the reactor when the action of the liq. jets has produced a dispersion of inert gas such that a coherent gas phase no longer exists. The reactor system in stage 1 consists of a jet reactor, a circulating pump and a heat exchanger. Stage 2 is carried out in a continuous flow-tube reactor. USE/ADVANTAGE - The process enables the prodn. of (I) with higher space-time yields (w.r.t. prior-art processes for PPE with comparable mol. wt.), shorter residence times, smaller amts. of off-gas and reduced by-prod. formation

Title: Continuous dyeing of cotton warp with indigo, vat or sulphur dyestuff or mixt. - in rope or slasher appts., with partial drying in absence of air before oxidn. in fresh air to enhanced build-up in layers
Inventor: SUETSCH FRANZ
IPC: D06P1/22
Filed: 1992-08-20
Abstract: In continuous dyeing of cotton warp yarn (I) with indigo and/or vat or sulphur dyestuff's in the presence of alkali and usual reducing agent (II) in rope or slasher appts., (I) impregnated with dyebath is partly dried in the absence of air, then oxidn. is carried out by admitting fresh air, with further drying and cooling. Pref. the total pick-up is 50-100% w.r.t. dry (I). The amt. of water removed in partial drying is at least 10, pref. at least 30% w.r.t. dry (I). Partial drying is carried out in steam for 2-20 ss, then the amt. and/or temp. of the fresh air is adjusted so that it near or pref. above the dew point. After the last impregnation and partial drying, oxidn. is carried out with H2O2 in the rinsing bath(s) instead of with fresh air. the amt. of (II) used is 1.3-1.9 times the theoretical amt. ADVANTAGE - The dyeing is improved considerably, since the dyestuff is built up in layers by impregnating partly dried (I) from a very small vol. of dyebath (addn. impregnation) and partly dried (migration) before oxidn. There is no risk of the dyebath overflowing. The vol. of bath lost when changed in 100 times smaller than usual and yarn loss and damage are reduced. The amt. of conc. dyebath needing regeneration by ultrafiltration is reduced, whilst the plant is smaller. (II) consumption is reduced, which compensates for the cost of energy for partial drying and also reduced environmental pollution. The need for separate predyeing for coloured resin (e.g. with orange for black denim) is eliminated and any hue can be produced by adding other vat dyestuffs to the indigo.

Patent DE-4235493-A1 (DE)
Title: Link connection between two articulated vehicles
IPC: B61D17/20
Filed: 1992-10-21
Abstract: The two rotary rings (5) of the rotary ring link (4) make possible bending movements between the two vehicles, and elastic parts, pref. rubber components (11), facilitate further movements between them. The one of the two rotary rings is rigidly connected to its corresp. vehicle, while the other is connected to its vehicle via the elastic parts.Forces directed in the vehicle longitudinal direction (3), i.e braking and drive forces, are transmitted between the two vehicles (1, 2) via pressure and tractive activation of the elastic parts, which under the influence of pressure forces are relatively slightly deformable. Bending movements between both vehicles around an axis (9) horizontal in the vehicle cross direction lead to tractive and pressure deformations of elastically deformable components.

Title: Internal combustion engine in the form of a rotary engine
Inventor: HEPPNER HARALD
IPC: F02B57/08
Filed: 1993-05-18
Abstract: The fuel-powered engines currently in service operate using reciprocating pistons and a crankshaft and generally require inlet and exhaust valves. The intention is to replace this complex construction by a simple system and increase the power and efficiency. The new system comprises a housing in which a rotor with fixed bosses is centrally mounted. A plurality of rotating cylinders with corresponding cylinder bores and pistons are mounted around this rotor on fixed hollow shafts. The exhaust conduit, the air supply, the injection nozzle and the spark plug for the associated rotating cylinder are accommodated in the hollow shafts. When the rotor begins to move, the boss of the rotor in front of the rotating cylinder pushes one piston of the rotating cylinder into the cylinder bore and compresses the air contained in this cylinder. This is followed by ignition, and the piston is forced out of the cylinder barrel. Since the boss is now behind the centre line through the rotating cylinder and the rotor, the piston pushes the boss onwards and the rotary motion of the rotor is maintained. The area of application is that of drive technology. <IMAGE>
