Abstract: Case 5-14251/ZFO/=   2,4-Diamino-6-halo-5-trifluoromethylpyrimidines having herbicidal activity Abstract 2,4-Diamino-6-halo-5-trifluoromethylpyrimidines of the formula              (I) wherein X is a halogen atom, especially chlorine or fluorine, and R1 and R2 independently of one another are each hydrogen, C1-C6-alkyl or C3-C6-cycloalkyl, or together form a C3-C7-alkylene bridge, have outstanding selective-herbicidal properties, and are suitable for controlling weeds in crops of cultivated plants, such as maize, cereal or soya-bean.  They are produced by aminating 2,4,6-trihalo-5-trifluoromethylpyrimidine, which for its part is obtainable by fluorination of 2,4,6-trihalopyrimidine-5-carboxylic acid.  The 2,4,6-trihalo-5-carboxylic acids are novel intermediates, and are obtained by oxidising 2,4,6-trihalo-2-methyl-, -halomethyl-or -formyl-pyrimidine in sulfuric acid by means of chromium trioxide.

Abstract: Abstract Germanium is recovered from aqueous solutions containing germanium, zinc, and antimony by sorption with an ion exchange resin which has as its matrix a backbone polymer to which are attached amine active groups chosen from secondary and tertiary amines and quaternary ammonium groups.  The resin exhibits a high selectivity ratio of germanium relative to antimony.  The method is particularly useful for the recovery of germanium from materials or electrolytes encountered in the recovery of zinc from ores and complex concentrates.

Abstract: INVENTOR:   EGON HANSCH INVENTION:  METHOD OF, AND APPARATUS FOR, PRODUCING STACKS             OF FLEXIBLE FLAT PRODUCTS, ESPECIALLY PRINTED PRODUCTS            ABSTRACT OF THE DISCLOSURE           The printed products are slid upon the rearmost printed product in order to form a stack in a lying configuration.  For this purpose there is provided a conveyor having at least one circulating chain at which entraining cams are mounted in a regularly spaced relationship.  The entraining cams act upon the trailing edges of the printed products.  A multiple number of pressing rollers press the stack, and these pressing rollers are mounted at a support disc.  The support disc is driven for clockwise rotation synchronously with the conveyor chain.  Each pressing roller each time presses upon the rearmost product of the stack.          The pressing roller which acts upon the stack is always located just in front of the leading edge of the product which is slid onto the stack and the pressing roller moves upwardly conjointly with the product in the product slide-on direction thereof.  While the stack is thus always under compression, the next following product can be slid onto the stack without experiencing a pressing action.

Abstract: ABSTRACT:           The invention relates to a switching mechanism for the deck of a magnetic-tape apparatus comprising a head-mounting plate (74) which can be moved forwards and backwards relative to the magnetic tape to be scanned, which plate is latched in the forward position in the play mode and, when unlatched, can be moved back under spring force to a standby position in which the cassette remains inside the deck.  The standby position can be reached when the end of the tape is reached or when an actuating rod (62) is depressed.  The actuating rod (62) comprises a guide slot (61) which effects unlatching of the head-mounting plate (74) and a switching surface (102) for the actuation of a drive switch (104) of the deck.  The head-mounting plate (74) carries a pivotal actuating member (89) which, when in its centre position during the return of the head-mounting plate (74) to the standby position can open the switch (104) and in a first pivotal position does not influence the drive switch (104). The actuating member (89) comprises a switching surface (107) by means of which the drive switch (104) is opened when the head-mounting plate (74) returns to the standby position and the actuating member (89) is in its centre position.  By means of a stop (95) on the actuating rod (62) the member (89) is moved to the first pivotal position if the ac-tuating rod (62) is moved in a specific direction after re-depression.  After this re-depression the switch (104) is closed during the return movement of the rod (62) in the opposite direction, a servo mechanism (64, 51, 52, 71) of the deck moving the head plate from the standby position to the play position.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved orthodontic bracket for mounting on the inside surface or lingual of a tooth having an upwardly opening longitudinal channel for receiving an arch wire therein.  The bracket includes an one-piece body having a locking groove formed in a front wall.  A locking pin is rotatably mounted in a key-hole shaped opening formed in the body and is removable therefrom for replacement if it becomes damaged.  The locking pin has a locking plate at one end of a shaft which is engageable in the locking groove of the body wall to se-cure an arch wire in the channel.  A locking tab is mounted on the other end of the shaft and moves along a ramped surface formed in a recess for securing the lock-ing plate in the locking groove.  Rotation of the lock-ing pin 180° moves the locking plate between an arch wire retaining or locked position and an arch wire receiving or unlocked position.  Rotation of the pin 90° from either position will align the locking tab with the key-shaped opening enabling complete removal of the locking pin from the bracket body.   A wedge block also may be mounted between the bracket body and inside surface of the tooth to change the mounting angle of the arch wire to obtain various force components on the tooth to move the tooth in various desired directions.
