Abstract: Glycidyläther ein- oder mehrwertiger Phenole von höchster Reinheit werden erhalten, wenn man die Halogenwasserstoffabspaltung aus den Halogenhydrinäthern der Phenole in wäßrigen Alkalien in Gegenwart quartärer Ammoniumverbindungen mit mindestens einem aiiphatischen C4-22-Kohlenwasserstoffrest, quartärer Phosphoniumverbindungen oder tertiärer Sulfoniumverbindungen als Katalysator durchführt oder in Gegenwart solcher Verbindungen, die im Reaktionsmedium «in situ» vor der Zugabe des Alkalis solche Oniumverbindungen aus den Halogenhydrinäthern und tertiären Aminen, tertiären Phosphinen oder Thioäthern bilden. Gegenüber den bekannten Verfahren läßt sich dadurch die Dehydrohalogenierung um ein Vielfaches beschleunigen, wodurch eine Produktionssteigerung erzielt wird. Außerdem werden durch Vermeidung von Nebenreaktionen bedeutend reinere Umsetzungsprodukte erhalten. Diese Glycidyläther finden Verwendung als niedrigviskose Gieß- und Lackharze in Form von Lacken, Klebstoffen, Formmassen usw., wobei übliche Härter eingesetzt werden können. Durch die niedrige Viskosität ist Verarbeitbarkeit erheblich besser sowie Aufnahmefähigkeit für Füllstoffe größer. Der extrem niedrige Gehalt an leicht verseifbarem Halogen bewirkt besonders günstiges Korrosionsverhalten.

Abstract: A method and apparatus for detecting the multiple feeding of documents being fed along a transport path, the documents having encoded characters arranged thereon in a predetermined manner. In a preferred embodiment of the invention, the documents are encoded with magnetic ink. Asensing member is positioned along the transport path in operative relationship with the encoded characters on the documents for generating a character signal in response to an encoded character being in operative relationship with the sensing means. A first circuit (86,126) is used for receiving the character signal and for generating a first time frame (65) which is not less than the maximum time a character is in operative relationship with the sensing member. A second circuit (130) is used for generating a second time frame beginning upon the expiration of the first time frame such that the sum of said first and second time frames is not greater than the time which elapses between the leading edges of adjacent characters coming into operative relationship with the sensing member. A third circuit (134, 136, 62) is used for generating an output signal indicative of a multiple-feed situation when a subsequent signal from the sensing means occurs during the second time frame.

Abstract: This method utilises conventional precipitation and flocculation products, such as iron or aluminum silicates, salts or organic polymers; but about0.1 to 10 (0.3 to 3) gr/lt of waste waters of alkaline or alkaline-earth alumino-silicates finely dispersed have been added, either amorphous to X rays or crystalline, and having the formula: x.Kat<u2/n>u.Al<u2>uO<u3>u.ySiO<u2>u wherein x = 0.7-1.5; y = 0.8-6; Kat = Na, K, Mg or Ca; n = 1-2. The compounds contain preferably crystallization water. The alumino-silicate is added to waste waters preferably in the form of an aqueous suspension (pH = 3.5 to 5.0); these waste waters are optionally previously brought to a slightly alkaline to a slightly acid pH (that is 5 to 10). The pH value is appropriately adjusted by addition of a strong mineral acid, preferably sulphuric acid. For treating waste waters from washing, those waters containing already x gr of alumino-silicates, the predetermined addition is reduced by an amount of x gr. The advantages: by comparison with already known methods, the method according to the invention allows the elimination of slurries to be improved and/or allows the amount of the precipitant to be decreased. The flocculation is enhanced and the slurries contain less water.

Abstract: A method of making an electrically-activated photoflash lamp which includes an ignition structure-consisting of a pair of metallic lead wires (21, -23) and primer material (25) disposed on terminations thereof. The structure is hermetically seated within the end of the lamp's glass envelope by firstly applying heat (e.g., by gas-oxygen burners) to the open end portion of the tubing member (35) (which eventually comprises the lamp's envelope) sufficiently to cause the heated glass to flow about the conductors. The final configuration of this end is achieved by introducing a gas within the tubing member's remaining open end to cause the heated end to expand to the desired shape, whereupon the end is permitted to cool. The hermetic seal, as achieved during the initial heating stage, is retained. The desired internal components (e.g., primer, combustible material, and combustion-supporting gas) are then added to the tubing member and the member's remaining open end sealed using a tipping off technique.

Abstract: A firemarm has a spring motor powered rotary magazine (16) having a plurality of circumferentially spaced cartridge chambers (18). The magazine is rotatable discretely to align the chambers with the barrel and a firing pin (28) of a firing mechanism (22). The magazine has stop pins (32) each being associated with a chamber (18) and being adapted to interfere with a first arresting face of a slide bar (36) operatively connected to the firing firing mechanism (22), to arrest the magazine in a non-aligned position. Depression of a trigger (24) cocks the mechanism (22) which urges the slide bar (36) rearwardly from underneath the stop pin (32). This allows the magazine to be rotated to an aligned position, the stop pin interfering with a second arresting face to arrest the magazine. Further depression of the trigger causes the aligned cartridge to be fired. Slightly lagging in time, the slide bar (36) moves forward, pushes the stop pin (32) from the second arresting face and thus allows the magazine to rotate. A succeeding stop pin (32) interferes with the first arresting face to arrest the magazine in a non-aligned position with respect to a succeeding chamber (18). 
<??>A loading opening is arranged in a back cover plate (62) to be aligned with a chamber (18) when a preceding chamber (18) is non-aligned with the barrel. Partial depression of the trigger (24) against a safety mechanism (30) allows the firing mechanism (22) to be partially cocked only and to advance the magazine as described above to allow loading of the magazine.
