The invention relates to a regulating arrangement in particular on packing machines for the feed of weblike packing material in register with decorations or folding indications, so-called crease lines, present on the web. In accordance with the invention the desired control is obtained by regulating the tension of the web with the help of a guide roller over which the web is passed. The speed of t...

The exhaust gas vapor generator has a main working medium flow which passes via a feed pump and economizer into an evaporator. Working medium is bled off as a component flow between the economizer and evaporator in order to heat the degasser. The heat of the component flow may be supplied via a heat exchanger disposed within the degasser or by a heat exchange with the condensate line within a heat...

In the start up of a paraffin isomerisation process operating at 100 DEG -204 DEG C in the presence of HCL or a compound decomposable to it as activating agent, the catalyst bed is brought to at least 100 DEG C, preferably, at least 130 DEG C before the feedstock and activating agent contact the bed. Starting up the process in conventional manner at low temperature and gradually bringing the temp...

Aromatic hydrocarbons are hydrogenated over a catalyst containing Group VIII noble metals supported on a carrier comprising 30-90% wt silica, 10-70% wt zirconia and 0-25% alumina.

PURPOSE:To improve the distribution of weight and to reduce the production of vibration and noise due to torque reaction of drive shafts of unequal length by disposing a drive train engine on a center line of a body of a 4-wheel drive system. CONSTITUTION:Crankshaft gears 4, 4a are faced at the divided ends of faced crankshafts 3, 3a, are divided to perpendicularly cross the crankshafts 3, 3a, and...

PURPOSE:Distribution of weight of a car of an all-wheel-drive system is improved by installing a driving shaft for rear wheels through a rotary engine. CONSTITUTION:The eccentric shaft 3 of a rotary engine 1 is hollow and clutches 4 and 5 and the main shaft 6 of a transmission 7 are also hollow. The driving force which was passed through the transmission 7 is distributed before and behind by a cen...

Fuel economy of a multi-cylinder internal combustion engine has been improved by allowing, when a vehicle is at a standstill, the engine to run on selected cylinders of all. The idling operation of the engine on the selected cylinders has been made smooth by the provision of a switch valve in a control circuit of the transmission. With the switch valve, as soon as an accelerator pedal is released ...

A hammer adapted to be pivotally mounted between a pair of rotors in a hammer mill has a pair of sidewalls each of which is adjacent a rotor. Each sidewall has a recess which collects small pieces of scrap which get trapped between the sidewall and the adjacent rotor. A portion of the recess extends beyond the outer periphery of the adjacent rotor so that scrap collected in the recess can be eject...

PURPOSE:By control of back pressure to accumulator for shift shock, chock is relieved in the whole range of the engine operation.

A process for the preparation of 2,3-dimethylbutene-2 is disclosed, which comprises the steps of converting isovaleraldehyde to isopropylacrolein, hydrogenating alpha -isopropylacrolein to form 2,3-dimethylbutanol, dehydrating 2,3-dimethylbutanol to form an olefin mixture comprising 2,3-dimethylbutene-1 and 2,3-dimethylbutene-2, and isomerizing the 2,3-dimethylbutene-1 contained in the mixture in...

In the method and equipment, the yarn support outer surface is drawn by means of a suitably sized die ring adapted to retain and slide the reeling waste all along the yarn support outer surface and strip the reeling waste therefrom. Suitable cutters operate on reeling waste, before the drawing thereof, in order to reduce the volume of reeling waste to be drawn and stripped.

PURPOSE:To prevent accidental moving of tractor which includes constant mesh transmission and creep transmission in driving system, by providing means to prevent frictional following of running line when the constant mesh transmission is neutral.

The herbicide acts specifically against wild oats. It contains, as active substances (a) 3-isopropyl-1H-2,1,3-benzothiadiazine-(4),3H-one 2,2-dioxide and (b) an N,N-disubstituted alanine derivative of the general formula in which Y and Z in each case represent either chlorine or fluorine and X represents oxygen or sulphur, while R represents one of the following groups: a group of ...

Rock chambers are used for storing liquids and gases, e.g. natural gas, at low temperatures. To prevent leakage through cracks in the rock surrounding the rock chamber the invention provides a method of sealing the rock by injecting a sealing agent through drill holes in the rock. The sealing agent solidifies owing to the lower temperature of the rock and/or stored medium. The injection is continu...

PURPOSE:High siliceous graulated porlous material which has superior heat insulation and reinforcing effect when it is used as a filling material in the vacuum layor of the vacuum storage container.
