Title: Whole citrus oil prodn. - by extraction of residues from citrus juice prodn.
Inventor: RITZENTHALER GILBERT
IPC: A23L27/12
Filed: 1974-12-09
Abstract: Whole citrus oil is produced by drying and finely comminuting the residues resulting from citrus juice prodn., extracting the resulting granules (particle size pref.1 mm) at least once with a solvent, the polarity of which depends on the matls. to be extracted, and evaporating mixt. to separate the solvent from the oil. The starting matl. is pref. dried to a residual moisture content of 10-13%, and the extraction is pref. carried out by infusion or percolation. The prod. may be fractionated to yield matls. for use as colouring agents (e.g. for fruit drinks or food prods)., as skin vitaminisation or as additives for toiletries or cosmetics. The prod. is rich in carotenoid pigments (provitamin A) and tocepherols (vitamin E) and can be used directly as a food colour or separated into fractions having the above-indicated utilities. The oil is obtd. from a readily obtainable raw matl. without the need for tedious separating out of component of this raw matl. such as seeds or peel.

Title: Vulcanising conveyor belts with embedded steel reinforcement cables - by resistance heating of cables in belt on reel
Inventor: AUFLEGER PAUL DIPL CHEM DR
IPC: B29C35/00
Filed: 1975-08-05
Abstract: Conveyor belt blanks of rubber, in which a core formed by steel reinforcement cables or similar metal details for supporting tensile loading, which do not come into contact with each other, is embedded between covering layers, are vulacnised in sections passed successively through a belting press and wound on a reel. The cables in the sections which have been vulcanised and wound up, are connected to an electrical power supply, and their temp. is raised by resistance heating to a point at or above the vulcanising temp. Effects an interlinking of the different elastomeric material layers in a manner approaching the ideal, and by ensuring uniformity in the flow of heat throughout the section of the belt, brings about a reliable bonding of the metal cords to the materials of the belt. The electrical heating of the wound-up belt brings about a two-stage vulcanisation with marked improvements all round.

Title: Automatic measurement of train length - using pulse transmitted from first vehicle to following one and each returning pulse to first one
Inventor: HUSCHKA HELMUT ING GRAD
IPC: B61L25/02
Filed: 1976-12-24
Abstract: The automatic measurement of train length process depends upon each vehicle being provided with a sender/receiver which can exchange data between them. The leading vehicle (TW1) sends a pulse to the next (second) vehicle (TW2) at the beginning of a measurement cycle (t=to). The pulse is delayed in the second vehicle by delta t and then transmitted to the third vehicle (TW3) and also returned to the first vehicle (TW1). Each next vehicle (TW3-TWn) operates in the same way, and pulses returned to the first vehicle (TW1) are counted, and when a time interval longer than delta t elapses after a pulse without arrival of a new pulse, the counter reading is transferred to a store, and then a new measurement cycle is started by transmission of a pulse from the first vehicle to the next.
