Abstract: ADJUSTABLE LENGTH DRILLING SUB                         ABSTRACT      An adjustable length drilling sub is disclosed for placing in a drill string between stabilizers to allow the distance between the stabilizers to be changed while the drill string is in the well bore to adjust the rate the angle of the well bore from the vertical is changing.  The sub includes an outer member and an inner member that extends into the outer member with an annular space bet-ween the members.  Protrusions in the form of drive pins mounted in the wall of the outer member extend into the annular space to move into and out of engagement with cavities formed on the outer surface of the inner member.          When the pins are in engagement with the cavities, torque in one direction and weight can be transmitted to the bit.          When the pins are rotated in the other direction out of the cavities, the members can be moved longitudinally relative to each other to change the distance between the stabilizers.

Abstract: ABSTRACT OF THE DISCLOSURE:            Reactive stabilising compounds able to stabilise organic polymers,  contain in their molecule a sterically hindered amino group and a hydrolysable silyl function.   Three examples are:       where m is zero or one, R' is hydrogen or methyl, Z is a bivalent group, R is an optionally substituted hydrocarbon radical, X is an alkyl radical, n  is one, two or three and Y is an organic or inorganic radical.   In stabilising organic polymers, these  reactive stabilising compounds can be hydrolysed at the silyl function with the formation of silanol groups, which are made to interact in order to form complex resinous stabilising structures.  These latter are added in stabilising quantities to the polymer to be stabilised.   The hydrolysis at the silyl function and the formation of the resinous structure may take place spontaneously within the polymer to be stabilised. Furthermore, the reactive stabilising compound may be added to the polymer after being stably supported on a solid support by reaction with an inorganic solid having surface hydroxyl groups.  Additionally, the reactive stabilising compound may be made to interact with the polymer so that the stabilising compound becomes chemically bonded to the polymer chains.   In all cases,  stabilised polymers are obtained containing the stabilising compound in a form which is not removable from  the polymer.   The process  for preparing these reactive stabilising compounds involves sylylation, while preparation of the stabilised polymer compositions involves hydrolysis and resinification of the reactive stabilising compounds.

Abstract: ABSTRACT OF THE DISCLOSURE A particulate built nonionic synthetic organic detergent composition includes a detersive proportion of a nonionic synthetic organic detergent and a building proportion, in combination, of a polyacetal carboxylate builder for the nonionic detergent and carbonate and bicarbonate builders for such nonionic detergent.  Such compositions are readily made by adding polyacetal carboxylate builder to the formula of a control detergent composition, with corresponding diminutions of other component(s), and have detersive powers superior to such control despite the decrease in proportions present of detergent and other builders.  Preferably, certain nonionic detergents, polyacetal carboxylate builders, carbonate and bicarbonate, in certain proportions, are employed to make a product of better detergency and physical characteristics, e.g., flowability.  Also disclosed are processes for manufacturing the described detergent compositions, in which processes spray dried builder base beads, containing carbonate and bicarbonate builder salts, have nonionic detergent and polyacetal carboxylate builder mixed with or applied to them.  Additionally described are pumpable and sprayable compositions of polyacetal carboxylate builder in normally solid, liquid nonionic detergent at elevated temperature, which compositions are suitable for applying the nonionic detergent and polyacetal carboxylate builder to the spray dried carbonate-bicarbonate base beads, preferably as a spray impinging on moving surfaces of such beads.

Abstract: ABSTRACT          It has been shown that magnesium silicates, particularly Mg-rich olivine, is very proper to neutralize waste sulfuric acid.  In said process a silica gel and a Fe/Mg-containing liquid are formed.  The experiments show that a distinct separation of the silica gel from the Fe-containing liquid is possible in the case where neutralization process is performed in an inert atmosphere.  After separation of the SiO2-rich gel a Fe-V precipitate may be formed by means of aeration.  The SiO2 gel may be rinsed well, so that an acceptable product is formed that e.g. is useful in the concrete industry.  The liquids formed are MgSO4 rich.  They may be drained simply into sea-water.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is a magnetic tape-based "voice mail" multi-user message system.  The invention uses a novel method of partitioning the tape and distributing a number of mailboxes on the tape in such a way as to minimize the average access time to individual mailboxes.   This provides the advantages of a truly random access multi-user disk-based system at a small fraction of the cost.  Incoming messages are recorded in random cells on a plurality of tracks on a tape.          A memory stores the location of the nearest available cell to the next position of the play/record head.  When an incoming message is received, the system directs the play/record head to the nearest cell in order to record a message.  When a user calls in to leave a message, after accessing the system, he inputs a DTMF code indicating that he desires to leave a message,  and another code indicating the mailbox address.          After recording the message in the nearest cell, the system stores  the  location  of  the  cell  in  the  directory  in association with the designated mailbox address.
