Abstract: ABSTRACT OF THE DISCLOSURE 1,2-dichloroethane is made by subjecting ethylene to an oxychlorina-tion reaction with hydrogen chloride and air in gas phase, at a temperature in the range of from 200 to 250°C and in contact with a fluidized bed copper-II-chloride catalyst on a carrier, wherein the reaction gases are cooled under pressure in two condensation stages, condensed 1,2-dichloroethane and water are removed and the bulk of unreacted starting gas and inert gas are recycled.  More specifically the reaction gases are delivered to a third con-densation stage and cooled therein under pressure down to a temperature within the range 5 to 18°C and to the extent necessary for the recycle gas to contain 0.5 to 3 volume % of 1,2-dichloroethano.  Next, the recycle gas is directly admixed upstream of the reactor, with a quantity of pure oxygen necessary to replace consumed oxygen and re-establish an oxygen content of 12 to 25 volume % therein.

Abstract: ABSTRACT OF THE DISCLOSURE      A sealing and filling material for metallurgical applications is consumable wood fiber, a non-consumable material from the group consisting of finely ground fired clay, silicon carbide, magnesite, burned dolomite, alumina, ground limestone and fine sand particles and a wetting solution to bind such materials into a yieldable, shapeable compound, said wetting solution consisting of an aqueous solution of calcium chloride and phosphoric acid.  This invention is distinguishable from others by reason of the inclusion of the consumable material therein and the ability of the material to be packaged if desired and/or used in a putty-like shapeable form to seal hot metal containing members to one another on a temporary basis so that the residue of the material can be easily removed for fast and easy resealing of the metal containing members for a subsequent use.

Filed: 1979-04-18
Granted: 1981-09-08
Abstract: Abstract A method of loading and unloading an open top or gondola railroad car utilizes a mobile, wheeled apparatus having power actuated front and rear boom structures.  A front supportive foot engageable with the upper surfaces of the railroad car sidewalls is connected to free ends of the front boom structure and similarly engageable rear supportive feet are connected to the ends of outrigger arms movable outwardly from the sides of the rear end of the mobile apparatus.  The rear boom structure includes an articulated material engaging grapple for loading and unloading operations.          During operation, the operator positions the mobile apparatus adjacent an end of the railroad car with the front boom raised and the front supportive foot engaged with the top surfaces of the car sidewalls.  The rear boom and material engaging grapple is folded close to the apparatus rear end and by coordinately operating the front and rear boom structures and the material grapple, the mobile apparatus is raised above the railroad car walls and moved forwardly until the front and rear supportive feet engage with the side wall upper surfaces.  Then, the rear boom and material handling grapple is used to load and unload materials relative to the railroad car.  Transfer from one railroad car to another in a train thereof is also accomplished by coordinated use of the front and rear boom structures.

Abstract: METHOD AND APPARATUS FOR THE TRANSMISSION   OF SPEECH SIGNALS                              Abstract of the Invention For the multiplex transmission of coded speech signals in periodic frames, single segments (blocks of coded samples) are selectively suppressed for redundancy reduction, and are replaced on the receiver side by optimally correlated subsections of equal length from previously transmitted segments.            On the transmitter side, a multiplicity of compare opera-tions are made for each speech signal, between the respective newest coded segment and a step wise shifted subsection window of previous segments, to determine the best correlated subsection, i.e. the one which is most suitable as replacement and the respective relative offset and correlation.            From a group of speech signals, the one signal, or several signals, having the best correlation is selected for suppression of a segment before transmission.  Instead of each missing segment an indication of the corresponding optimum offset is transmitted in the frame header.  In the receiver for each speech signal a few previous segments are kept in storage from which then, with the aid of the received offset indication the optimally suited subsection can be selected and used as replacement.

Abstract: Abstract A coupling arrangement is disclosed for establishing a rotary connection between an axially movable armature element and a rotary drive hub, which transmits torque from the hub into the armature while allowing limited axial movement of the armature against an axial spring force exerted by the coupling arrangement.  The coupling arrangement includes d series of circumferentially extending leaf springs, each having one end pinned to the armature and the other riveted to the hub.  The circumferential pattern of the spring links is such that each link overlies other spring links in the series to enable the length of the spring link to be great enough to insure adequate flexibility of the links to accommodate axial movement of the armature. while enabling a sufficient number of the spring links to be disposed about the armature and hub axis to adequately transmit the torque through the clutch unit.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for monitoring the degradation of oil, particularly crankcase oil.  A first sensor includes creep material position-ed under constant stress in thermal contact with the oil to act as an analogue computer as it changes its length in response to temperature and the time at that temperature to register the degradation of oil due to the oil's oxida-tion.  In addition, a second sensor registers the contamination of the oil by adding the number of times the oil is heated but not heated to a high enough predetermined temperature to disperse the water, acids and sludge which contaminate the oil.  When the combination of these outputs reach a predeter-mined limit, a signal is provided.  This is accomplished by an apparatus including a generally U-shaped bracket with a platform movably supported on the bracket for upward movement against a spring.  A rod extends through the platform and is connected to a diaphragm which, in turn, is subjected to oil pressure to move downwardly, thereby moving the rod downwardly.  A creep material is supported on the platform and extends upwardly in the direction of the rod to a distal end and is placed under a constant stress by a spring reacting between the distal end and the platform.  The creep material changes in length exponentially when subjected to temperature and time, the operand of the exponent being the base of the natural system of logarithms.  Associat-ed with the platform is a metal member having a pair of gripping tangs engaging the rod so that when the rod moves downwardly and returns after the oil pressure is released it will move the platform upwardly relative to the bracket unless the oil reaches a predetermined temperature at which time the tangs will move away from the rod allowing the rod to freely return upwardly without moving the platform.  When the combination of movement or elongation of the creep material and platform movement upwardly is sufficient that the distal end of the creep material contacts the upper portion of the bracket an electrical signal is provided indicating that the oil is sufficiently degraded to be replaced.
