Title: Inhibiting wax deposition from oil - by an ethylene-unsaturated ester copolymer
IPC: C09K8/524
Filed: 1972-05-10
Abstract: Deposition of wax from an oil is inhibited by incorporating in the oil a copolymer of ethylene and a monoethylenically unsaturated ester which is (1) a vinyl or allyl ester of saturated aliphatic carboxylic acid or (2) a saturated aliphatic ester of an unsaturated aliphatic aciboxylic acid. The pref. comonomer esters are vinyl acetate, ethyl acrylate and methyl methacrylate. The pref. copolymer is an ethylene/vinyl acetate copolymer, partic. one contg. 35-55 wt.% vinyl acetate and having a melt index of 1-600 g/10 mins. and esp. a copolymer contg. 37-42 wt.% vinyl acetate and having a melt index of 45-70 g/10 mins. The inhibitor is partic. useful for adding to a well producing a wax-contg. crude. In addition to inhibiting the deposition of wax, the copolymer is also useful in removing previously deposited wax from metal surfaces.

Abstract: Abstract of the Disclosure ABSTRACT OF THE DISCLOSURE      Solid particulate materials are bonded together to form a shaped article by (i)  forming a mixture of the particles and an anserobically-curing adhesive and moulding the mixture to the desired shape, and (ii) causing the adhesive to cure and bond the particles together by maintaining the shaped article in a substantially oxygen-free environment.      The anserobic adhesive may comprise, as monomer, an ester of an acrylic acid, with a hydroperoxide or peroxide as a polymerisation catalyst, and  the oxygen-free environment may be produced by displacing air with nitrogen or other inert gas or vapor.      The method described is particularly suited for the production of foundry moulds and cores from sand or other particulate material.

Abstract: Abstract of the Disclosure Cleaning apparatus for cleaning material from a support surface includes a cleaning blade with a tip and a first atom portion adapted to be mounted as a scraper blade in contact with the surface to be cleaned.  The lower stem portion extends towards the tip portion with a component in the direction of motion of the surface to be cleaned. When such a blade is used in conjunction with another scraper blade which is located downstream, the lower stem portion acts to deflect material moving in opposition to the direction of motion of the surface being cleaned away from that surface. The tip and upper stem portion act as a separate scraper blade.

Abstract: ABSTRACT                Disclosed is a system for locating a transmitter arranged for transmitting frequency-modulated signals. The system supplies data about the angular deviation between the direction of the transmitters considered from a reference point and a reference axis passing through that point and comprises two antennas disposed on the reference axis symmetrically relative to the reference point, and a receiver having two mixers which receive, on the one hand, the respective signals from the two antennas through time delay elements and, on the other hand, the signal from one of the antennas through a circuit which provides, during a given period of time, a linear phase shift.  The beat frequencies at the mixer outputs are measured by frequency meters during said time period and the desired information is given by the relative deviation between the output signals of the two frequency meters.

The bobbin drive mechanism includes a second circular table coaxially aligned with the  first  table and adapted  to rotate relative thereto.   A circular array of pairs of shafts corresponds to the array of inner strand supply bobbins and each is mounted for rotation on the second table.   The shafts include a planetary gear fixedly mounted thereon in alignment with and engaging a circular gear on the first table to cause rotation of the shaft during relative rotation of the table.  A crank is fixedly mounted on an end of each shaft to rotate therewith.   A pair of radially extending dogs associated with each inner strand supply bobbin are mounted on the second table and aligned with a slotted fitting of the associated inner strand supply bobbin.  Linkage between each dog and its respective crank causes inward and outward movement of the dog during rotation of the shaft.  Each of the cranks of the pair of shafts is prepositioned to cause one of the dogs to be in driving engagement with the slotted fitting of the inner strand supply bobbin as the other of the dogs is displaced therefrom to allow the strand from the outer strand supply bobbin to freely pass therebetween.

Abstract: ABSTRACT     Heat-recoverable articles, especially heat-shrinkable tubular articles, having an open end are formed so that the section adjacent said open end has a lower recovery ratio than a section adjacent thereto, thereby substantially reducing the risk of splitting when the degree of recovery is high or in applications where a high degree of unrecovered strain remains after recovery about a substrate such as a supply line.   A preferred article is a tubular end cap in which the open end section has a larger circumference after unrestrained recovery than the adjacent intermediate section.   Such a cap is especially useful for encapsulating the termination of a multi-wire telephone cable.
