Title: Process for removing caffeine from green coffee beans
Inventor: KATZ SAUL NORMAN
IPC: A23F5/20
Filed: 1984-08-07
Abstract: A process is described for removing caffeine from both moist and dry green coffee beans, in which liquid or supercritical carbon dioxide is used as extraction medium. Dimethyl sulphoxide is dissolved in the extraction medium prior to the contact with the beans. The degree of extraction is considerably improved, that is in particular in a preferred process in which the dimethyl sulphoxide is used close to the saturation level.

Title: Roof bolt
Inventor: HOLTMANN THOMAS
IPC: E21D21/00
Filed: 1985-02-28
Abstract: In a roof bolt with a stem and a head which is arranged on this stem and is provided with engaging elements which engage on the stem, the engaging elements are designed as cutting edges, and prominences are provided on the periphery of the roof-bolt stem.

In order to be able to carry out the closure of the seaming edge easily and rapidly by an assembly process which involves little effort, the invention envisages that the seaming edge be clamped between a driving roller and a counter-roller serving as an abutment and be moved relative to them by rotary movement of the driving roller, that, following the driving roller and the counter-roller, the seaming edge be passed between at least one pair of tapered rollers and bent through a predetermined angle in the closing direction by the said pair and that the pair of tapered rollers is followed by at least one hammering ram which, in periodic striking movements, brings the pre-bent seaming edge guided past it into the final, closed position.
Patent DE-3511192-A1 (DE)
Title: Unit for applying an adhesive composition onto large surfaces
Inventor: MORYS KLAUS
IPC: B05C11/10
Filed: 1985-03-25
Abstract: The invention relates to a unit with which an adhesive composition, such as for example a cold bitumen adhesive composition, is applied onto roof surfaces. The unit contains a pan for softening the cold bitumen adhesive composition, a pump for conveying the softened cold bitumen adhesive composition and a petrol engine to drive it. It should also be possible to operate the unit at low temperatures. To this end the exhaust gases from the petrol engine are guided through the pan and past the pump. The petrol engine also drives a generator. The latter feeds a resistance heater provided in a hose connected to the pump. The cold bitumen adhesive composition fed into the pan can thereby be heated and softened, conveyed by the pump and transferred further through the hose to the site of application without it hardening in the hose.

Title: tert-Octylhydrazine, its salts and derivatives
Inventor: MACLEAY RONALD E
IPC: C07C239/00
Filed: 1985-10-09
Abstract: Mixtures of di-tert-octyldiazene (tert-octyl meaning 1,1,3,3-tetramethylbutyl) and tert-octyl secondary or primary alkyldiazines are prepared by reacting mixtures of tert.-octylamine and a primary or secondary alkyl primary amine with sulphuryl chloride and oxidising the sulphamide mixture obtained with a basic bleaching agent. The diazene mixture is then heated in a chlorinated solvent, the di-tert-octyldiazene decomposing and the asymmetric tert-octyldiazine rearranging to give a tert-octylhydrazone. The tert-octylhydrazone is extracted from the solvent with dilute acid, the extract of the acidic solution is heated to 40-50 DEG C and the ketone formed is stripped off under reduced pressure. In order to form tert-octylhydrazine the acidic solution is neutralised. tert-Octylhydrazine is an intermediate which can be reacted with various compounds, such as e.g. ketones, aldehydes, acids, acid chlorides, isocyanates, chloroformates and sulphonyl chlorides to give various tert-octylhydrazine derivatives.
