The printing and post-processing system according to the invention provides as a compact integration unit a computer unit (10) for commanding with programs each component of the system for selective and controllable operation, a printer unit (12) selectively operable with program to print the sheet to be mailed, a folding unit (16) for folding the sheet with different folding modes including wrap and Z form foldings, a conveyor unit (18) for conveying the folded sheet with a selectively added enclosure to the enveloping or storing position, an envelope tray unit (20) for stacking a plurality of envelopes and discharging the same by piece, an insertion unit (22) for meeting the envelope with the folded sheet for subsequent insertion thereinto, a sealing unit (24) for sealing a flap of the envelope, a receiver unit (26) for receiving and storing the sealed envelopes therein, an enclosure supplying unit (28) for selectively supplying an enclosure to the conveyor unit.
摘要:
Lubricant concentrates and aqueous lubricant solutions containing at least one polyamine derivative of a fatty amine and/or a salt of such an amine. The invention also relates to a process for the production of the lubricant concentrates and to the use of the lubricant concentrates and the aqueous lubricant solutions as chain lubricants in the food industry.
摘要:
A plant for the processing of exhaust gases of an electric melting furnace for steel is disclosed, which allows to improve the cleaning of heavy-metal-containing exhaust gases from electric arc furnaces for steel production from scrap, which allows to decrease the energy use for capturing waste from the exhaust gases, which avoids the odor molestation by the waste gases generated in connection with an electric melt furnace operation during the preheating and for making useful the exhaust gases for the smelting under incorporation of the drying of oil-containing roll sinter muds, where simultaneously the oil-content of these roll sinter muds is used for saving of electric arc melting energy.

A clamping force relates to a clamping-force transducer for rotating clamping devices which has at least two opposite pressure pieces adapted to be placed on the clamping elements of the corresponding clamping device and arranged in a support member, at least one of which pressure pieces acts on a force transducer the measurement values of which are taken from the rotating clamping-force transducer housing via a stationary transfer housing. To adapt the clamping-force transducer simply to clamping devices having a different number of clamping elements and to different clamping diameters without the rigidity of the clamping-force transducer being changed thereby, the pressure pieces are arranged replaceably but fixed on the arms of a multi-arm measurement member, at least one arm of the measurement member being developed as the force transducer. The measurement member preferably has a star shape with six arms, each of which has a connection for a pressure piece. In order to determine the corresponding speed of rotation at the same time as the clamping force, a pulse transmitter for a pulse receiver arranged on the fixed transfer housing is arranged on the rotating clamping-force transducer housing.
摘要:
Apparatus for isolating and feeding objects, particularly sweets, to a pang machine in which objects are transported on a conveyor in a longitudinal row closely one behind the other, displaced sideways one at a time and accelerated to a higher speed spaced longitudinally from one another. Sideways displacement is provided by pressure pieces moving longitudinally with the objects and providing abutment stops for the next succeeding object to be isolated. Part of the rear face of each object is exposed by the sideways motion and a dog of a dog-chain engages the object at this point at the same speed as the pressure piece and then accelerates the object engaged by it such that the row of objects is longitudinally spaced one from another.
摘要:
A cylinder lock which includes plate tumblers in a lock cylinder and a locking channel arranged in a lock casing wherein, when the key is pulled out (locked position of the lock), spring-loaded plate tumblers engage with their locking ends into the locking channel up to an extension length determined by locking stops. The lock casing is provided with an escape channel diametrically opposed to the locking channel for enabling a free resetting motion of the plate tumblers with their counter ends during an insertion of the key. The plate tumblers have, in their key cutouts, tumbler edges arranged at levels corresponding with an associated key cutout depth and, with a key being inserted (free position of the lock), can be reset into the lock cylinder. Stops are provided for limiting the resetting motion of the individual plate tumblers in the escape channel at insertion depths and a varying arrangement of the blocking stops is made in dependence upon a height of the respective tumbler edge.

The present invention for the treatment of endometriosis relates to providing a parenteral dosage form (delivery system) for the controlled release of an aromatase inhibitor (AI) in a daily release rate that does not induce stimulation of the ovaries by negative feed-back of the pituitary-ovarian-axis (which would cause secretion of gonadotropins and stimulation of ovarian follicular growth) and a gestagen in a daily release rate below the ovulation inhibition dose that provides contraceptive efficacy based on local effects (e.g. reducing and thickening of the cervical mucus impairing sperm ascension, effects on the endometrium and on tubal motility impairing implantation and egg transport).
摘要:
The invention relates to aqueous, clear solution-forming, substantially soap free lubricant compositions and to the use of the lubricant compositions according to the invention, especially as lubricants for the transport of glass bottles or poly(ethylene terephthalate) bottles. The substantially neutral aqueous lubricant compositions (pH 6-8) contain alkyl benzenesulfonates, partial phosphate esters with alkoxylated aliphatic alcohols, and aliphatic carboxylic acids, optionally in addition to typical solubilizers, solvents, foam inhibitors and disinfectants.
摘要:
To make the passenger seat for the airplane as light as possible while satisfying safety requirements, some or all the essential components are made with a sandwich-like structure, especially from sandwich panels. These sandwich panels can be made from a plurality of covering layers with a light but strong supporting core (e.g. with a honeycomb structure) interposed between pairs of covering layers.
