Inventor: HEHL KARL
IPC: B29C45/60
Filed: 1991-09-12
Abstract: In a plasticizing assembly for use in an injection molding machine, which assembly has a high-pressure chamber and a low-pressure chamber, which contains the feed screw, and a plurality of fixing screws disposed on a circular line, a connecting sleeve is provided, which partly surrounds the plasticizing cylinder or a rear section of a bipartite plasticizing cylinder and surrounds also the nozzle body or a forward section of a bipartite plasticizing cylinder in part of its length and is secured to the plasticizing cylinder or to its rear section. The fixing screws are screwed in and axially supported in tapped bores of the connecting sleeve and at their end faces bear on abutment faces of the nozzle body or of the forward section of the plasticizing cylinder. As a result, a replacement of the nozzle body or of the forward section of the plasticizing cylinder can be effected in a simpler manner and more quickly and will require lower physical forces and a simpler implement and it is possible to supply energy at a higher rate.

Title: Thermal recycling of household and industrial waste - by pyrolysis in absence of air, comminution, sizing to obtain coke-like enriched fines, degasifying using oxygen-contg. agent and gas purificn.
Inventor: SCHINGNITZ MANFRED DR ING
IPC: C10J3/66
Filed: 1991-11-29
Abstract: Thermal recycling of waste material (I) by a combination of known processes such as pyrolysis, comminution, sizing, degasification and gas purificn., comprises pyrolysing (I) in the absence of air at up to 800 deg.C in a carbonisation process to produce a gaseous hydrocarbon-contg. pyrolysis crude gas and a solid pyrolysis residue. The crude gas is removed at temperatures higher than the condensn. temp. of the gaseous hydrocarbons. The solid residue is sepd. by comminuting and sizing to produce coke like enriched fines and an organic contaminant free coarse material consisting of metallic components. The crude gas, fines, and additional liq. fuel are fed into a degasification reactor and auto-thermally reacted with a free-oxygen contg. degasification agent to form a CO- and H2-contg. gas and a mineral residue. The ratio of free oxygen to carbon in the gas, fines and fuel is controlled so that the temp. in the reactor is above the melting temp. of the mineral residue and a liquid slag is produced. This slag is cooled, granulated in contact with water and removed from the reactor. The CO- and H2-contg. gas is cooled and liberated from sulphur cpds., halogenated hydrocarbons and aerosols. The coarse prod. is recycled in a specific process. USE/ADVANTAGE - Used to recycle waste such as household waste, plastic-contg. industrial waste, dye residue, used tyres, shredder-lightweight waste from motor car recycling or oil-contaminated waste without extensive pretreatment.

A glutamine antimetabolite may additionally be used. The DNA may also be used for a GA isolation from human tissues or fluids. The GA can be produced cheaply and with minimal contamination of other substances. Having a lower mol.wt. than native GA, it can be more readily distributed in tissues and causes fewer immunological problems than known GAs. Large scale prodn. allows clinical tests in neoplastic tissues where glutamine levels are often increased.

Title: Start control for burner - using progressively reduced airflow until burn is detected by ignition electrodes
Inventor: BERG JOACHIM
IPC: F16B5/12
Filed: 1991-12-20
Abstract: The fuel fired burner is supplied with a metered fuel flow and a regulated airflow. To start the burn, irrespective of temperature, a first start attempt is made with the normal airflow e.g. that airflow corresponding to normal operating temperatures. If this start fails then a restart is tried with a reduced airflow. The airflow is progressively reduced until burn is achieved, when the normal airflow is reset. If the burn is not started after a set number of attempts than a flushing sequence clears unburnt fuel and the next start sequence starts at a lower airflow level. If no burn is achieved within a set programme then a failure mode is indicated and the system switched off. ADVANTAGE - Reduced emission products, simple start control for burner.

Also claimed is an assembly with at least one twisting spindle with an undulating ring near the yarn balloon for the yarn component to pass through or round, where the side in contact with the yarn has an edge structure which deviates radially from a circular shape.      The ballooning limit has an inner cylindrical surface to make contact with the ballooning yarn component at intervals. The yarn is formed into lateral waves structured to make the required contact and non-contact times, and the wavelength of the yarn gives a standing wave within the limit. The ballooning limit can also have coils in a single- or multi-pitch spiral to give the contact and non-contact times with the yarn. The pitch of the spiral coils is in a ratio of more than 10:1 to the pitch of the yarn passing round, and the coil thickness has a ratio of less than 1:3 to the gap to the neighbouring coils.
