Abstract: CLAMPING LOCK FOR LOOPED TIES                     Abstract of the Disclosure A clamping lock is provided for use with a looped tie in a form for settable casting compositions, such as concrete, which lock is provided with protrusions on each of a pair of clamping members to fit into aligned connector slots of a pair of rails of adjacent panels of the form to properly position and firmly secure the lock to the form.  The securing of the clamping members on the rails also holds adjacent panels of the form together.  The rails are provided with tie notches which when panels are placed side by side and properly aligned the tie notches form tie slots through which a tie having loops at each end can be extended between panels of opposing sides or walls of the form structure.  A tie opening is formed in the clamping lock through which the loop of a tie is adapted to extend.  An anchor lock having a tapered arm is mounted on the clamping lock so that its arm can enter into a tie loop extending through the tie opening to secure the tie to the clamping lock and to tension the tie.  Various means are provided to secure the clamping members against the rails.

Title: Direct esterification to monomeric and oligomeric  silicic acid alkyl esters
Inventor: KOTZSCH HANS-JOACHIM
IPC: C08G77/02

Abstract: ABSTRACT OF THE DISCLOSURE:         A process for the production of ortho silicic acid esters and their oligomers of the general formula:                             in which R represents an alkyl radical having from 1 to 12 carbon atoms or an alkyl radical of 1 to 12 carbon atoms containing at least one oxygen or sulfur atom in its chain and n is ranging between 1 and 10, by esterification of chlorosilanes or chlorosiloxanes with primary alcohols, optionally in the presence of water.  This process is characterized in that the alcohols are directly introduced into the liquid chlorosilanes or siloxanes without contact with the gas and, upon completion of the reaction, the rest of the hydrogen chloride formed during the reaction is removed from the reaction zone. The invention enables one to control the complete esterification of the chlorosilanes and chlorosiloxanes in such a way that the required ester is formed in the highest possible yields and is as free from impurities as possible.

Abstract: ABSTRACT OF THE DISCLOSURE In a nozzle assembly for vacuum unloading of dry, bulk, particulate material, one or more mechanical aerators are mounted on horizontal axes with a scraper positioned intermediate the aerators. Dry bulk particulate material is mechanically aerated, by the rotation of the aerators, and fed to the suction end of the nozzle. Each mechanical aerator includes a plurality of paddles mounted on an elongated horizontal shaft and the paddles and the scraper together enable the nozzle to clean down to the bottom of a barge or ship in which the particulate material is stored. The suction end of the nozzle includes a shroud, to control dust emission, and has a flared end which, in combination with the aerators and the scraper assists in breaking up any lumps in the dry bulk particulate material and in reducing the amount of particulate material which becomes airborne.

Abstract: IMPROVED CIRCUIT INTERRUPTING DEVICE           Abstract:  An improved circuit interrupting device includes a pair of contacts which are relatively movable and between which an arc is established.  Following melting of a fusible element, a stored energy source rela-tively moves the contacts apart to elongate the arc, and a container of pressurized dielectric fluid simultaneously directs fluid from a port at the arc.  The fluid and the arc elongation ultimately extinguish the arc.  A fusible diaphragm normally closes the port to prevent the escape of fluid, and also, due to its mechanical attachment to the contacts, restrains relative movement therebetween.  The fusible element is so connected as to normally shunt current through the device away from the diaphragm.  When the fusible element melts, all of the current through the device flows through and melts the diaphragm.  As the diaphragm melts, two results are effected:  fluid is permitted to escape from the port, and relative movement between the contacts occurs.

Abstract: PIVOTABLE MEANS FOR DECREASING DRAG EFFECTS ON A GENERALLY CYLINDRICAL DREDGE PIPE                           ABSTRACT         This invention provides a substantially flat plate hingedly connected to a substantially cylindrical pipe intended to be moved through the water in a generally longitudinal alignment, the plate extending behind the pipe during movement through the water.  The hinged plate can be formed in modular sections, one or more plate sections being hingedly connected to a pipe section. Individual pipe sections are intended to be joined together to form a single longitudinally extending pipe, for example, for use as a dredge pipe in deep ocean dredging.  The hinged plate can be directly connected to the main dredge pipe or the hinged plate can be connected to a substantially smaller diameter pipe which is in turn connected to the main pipe.  The plate is preferably not less than two inches away from the outer surface of the main pipe.  The plate is especially effective for the movement of substantially vertical pipe through water at speeds of up to about two knots.

Abstract: ABSTRACT OF THE DISCLOSURE       A process for refining a metal bath in a converter by oxygen blowing, particularly a molten metal liquid bath contain-ing cold, solid substances, notably of scrap.  Oxygen is dis-tributed over the surface of the bath, so that there will be an after-combustion of CO released in the course of decarbo-nization.  The thickness and consistency of a slag layer formed over the bath is actively regulated by injecting a rising inert gas through the bottom of the bath.  The flow of rising gas may be regulated depending upon the oxygen content in the fumes of the converter, or upon the intensity of the sound emitted by a lance blowing oxygen through the top. In this manner, the metal-slag interface is continuously being regenerated so that the slag is continuously being deoxidized and cannot foam.  The absence of a foamy consistency enables the energy resulting from the after-combustion of CO to radiate which makes it possible to increase the additions of solid scrap.
