Abstract: 1,074,058. Casting piles in situ; ground anchors. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 26, 1965 [Oct. 28, 1964], No. 45262/65. Headings E1B and E1H. A tubular pile (18), Fig. 1 (not shown), lodged in a loose or unconsolidated earthformation (19), comprises a closed lower-end (24) and a plurality of holes (25) adjacent thereto through which a liquid mixture of a polyepoxide material and a curing agent is ejected to form a solid footing (26). Alternatively, the pile has a reduced diameter at its lowermost end where a plurality of fins or strut members (30), Fig. 4 (not shown), are attached between rows of holes (25). While the pile is being driven, the holes (25) may be closed by corks or metallic plugs which are removed by the ejection of said mixture. When a quantity of said mixture has been poured into the pile a flexible ball (22) made of e.g. synthetic rubber, is driven downwardly to force the mixture through the holes (25) by pressurized water until the ball abuts an annular shoulder (23), the water being stored in a reservoir (10) and pressurized by a pump (14). The pile is provided with a removable cap or closure (21) a its uppermost end. A ground anchor (37), Fig. 5 (not shown), may be secured in an unconsolidated earth-formation (35) by a block or bulb (38) formed by said mixture. The anchor is attached to a cable or guy line (36) that passes through a pipe (39) for conveying said mixture in a pressurized condition to the bottom of a shaft or hole (34) wherein the anchor is lodged, sealing of the pipe relative to the shaft being effectd by a inflatable ring (40) until the mixture solidifies. The shaft (34) is filled with excavated material after the ring (40) has been removed. The polyepoxide material has essentially more than one epoxy group per molecule on average whereas the curing agent is characterized by having a plurality of amino hydrogen atoms and being present in the said mixture by an amount that is at least 5% stoichiometrically in excess of the quantity of polyepoxide material. Many Examples of such polyepoxide materials and curing agents are given.

Abstract: 1443499 Stripping bobbins LEESONA CORP 22 Oct 1974 [25 Oct 1973] 45558/74 Heading D1F In a method of preparing spent bobbins for re-use e.g. in a loom, the bobbins are moved along a common path of travel and a downstream bobbin therein is tilted towards the upstream direction and an upstream bobbin enabling these bobbins to be concurrently stripped of waste yarn. In the operation of the apparatus shown, as a bobbin B drops through a chute 11 onto a base support 14 any ends of remanent yarn strands 12 are picked-up by a rotary brush 10 to cause such strands to be engaged and unwound by a stripping cone 13. The bobbin is concurrently urged along support 14 and initially positioned between a guide 30 and an opposing guide 50 whereat the stripping operation starts. Bobbin is next moved to a position between guide 30 and opposing guide 48 and tilted back in an upstream direction for continued stripping following which it passes to downstream apparatus ,(not shown). The various guides are adjustable to define the width of the path of travel of a bobbin e.g. mounting brackets therefor are variably positionable, whereby guides such as 30 .may be moved towards and away from opposing guides such as 48, 50.

Abstract: 1,074,219. Valves. BOISE CASCADE CORPORATION. Oct. 28, 1965 [July 26, 1965], No. 45701/65. Heading F2V. With a horizontally-disposed valve 2 connected by an annular lip 21 to the discharge sleeve 20 of a fluid container 18, the carton 19 which is tilted to the horizontal position, the fluid from the container flows by gravity to fill the valve chamber 15. Upon depressing a diaphragm 30 to axially displace the frustoconical closure-member 42 from its seat 10 fluid passes through an outlet 64, and some enters an auxiliary chamber 62 via a space 15a in a closure-member boss 40 and openings 60 in a wall 4, as well as the space between a tubular extension 32 of the diaphragm and a non- circular opening in the wall 4 through which it passes; the boss 40 is secured within the extension 32. When the diaphragm is released it progressively returns to the position shown, the fluid in space 15a being forced into the chamber 62. The length of the outlet 64 is selected to afford a level of surface-tension which prevents dripping whilst the flow area thereof is determined as a function of the closure member dimensions, conicity and material, as well as the fluid viscosity. The angle of the closure member is one quarter of a degree more than the seat angle α to provide for deformation of the closure member and hence an effective seal with the seat 10. The seat may embody a pair of annular ribs, one on each side of the outlet 64. The valve is disposable, the body being of impact styrene and the closure member and diaphragm of ethyl vinyl acetate.

Filed: 1964-11-13
Abstract: 1,031,968. Feeding webs. RADIO CORPORATION OF AMERICA. Nov. 13, 1964, No. 46334/64. Heading B6B. [Also in Division G5] A relatively soft magnetic tape 20, Fig. 4 (not shown), is fed over pairs of vacuum-supported grooves 148, 150, extending across a guide plate 106. These grooves cause the passing tape to be temporarily corrugated, increasing its transverse rigidity at points up- and down-stream of a multiple-track head 24, so that edge-guides, fixed 164, 166 at one side of the tape, and spring-urged 114, 116 at the other side, where these corrugations occur can more vigorously effect alignment of the record tracks with the head elements 142. The wearing portions of the edge guides may be constituted by slips of synthetic sapphire cemented to the guide bodies. The tape is driven in either direction by counter-rotating vacuum capstans associated with vacuum columns in normal fashion, Fig. 1, and when neither capstan is activated to drive the tape, the friction applied by the corrugating grooves provides sufficient braking to prevent tape drift.

Title: Method of manufacturing polyamide-acids
IPC: C08G73/14
Filed: 1964-11-18
Abstract: Polyamide-acids are prepared by reacting a tricarboxylic acid anhydride mono acid halide which contains a trivalent radical of at least 3 carbon atoms, the anhydride carbonyl groups being on adjacent carbon atoms with a diamine having at least 2 carbon atoms, in an organic solvent.  The acid halide group may be joined to a carbon atom separated by at least one carbon atom from those bearing the anhydride group.  The acid may be aliphatic, alicyclic, or aromatic and the halide may be F, Cl or Br.  A suitable compound is trimellitic anhydride monochloride.  The diamine may be substituted with halogen, methoxy, or alkyl groups. Compounds specified include m-phenylene diamine, bis(4-aminophenyl)ether, bis(4-aminophenyl) methane and bis(4-aminophenyl) sulphoxide. The reactants may be heated in equimolar amounts in a solvent at up to 50 DEG  C.  The reactants and solvent may be mixed in any order but if the solvent is first added to the acid anhydride monohalide an adduct may be formed. This can be avoided by dissolving the diamine and acid anhydride derivative in different solvents, e.g. the former in a basic solvent, e.g. dimethyl-acetamide, to neutralize the eliminated HCl and the latter in a neutral solvent, e.g. benzene or xylene.  A base, e.g. NEt3 or pyridine may also be present to remove eliminated HCl.  The product may be used as an insulating varnish, as an adhesive for metal or glass fabric or to make films.  When heated it is converted to the corresponding polyamideimide.ALSO:Polyamide - acid solutions suitable for application to glass fabric and say copper wire are prepared by reacting a tricarboxylic acid anhydride, which contains a trivalent radical of at least 3 carbon atoms the anhydride carbonyl groups being on adjacent carbon atoms with a diamine having at least 2 carbon atoms in an organic solvent.  When heated the polymer coating is converted to the corresponding polyimide.
