Title: Improved storage wrap material
Inventor: WORTHINGTON PETER
IPC: C09J7/22
Filed: 1997-01-09
Granted: 2001-11-28
Abstract: The present invention relates to sheet-like materials suitable for use in the containment and protection of various items, as well as the preservation of perishable materials such as food items. More particularly, the present invention provides an improved storage wrap material comprising a sheet of material having a first side and a second side. The first side comprises an active side exhibiting an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. The storage wrap material may be activated by different approaches, but in a preferred embodiment the active side is activatible by an externally applied force exerted upon the sheet of material. The force may be an externally applied compressive force exerted in a direction substantially normal to the sheet of material. In accordance with the present invention, the storage wrap material is selectively activatible by a user in discrete regions to provide adhesive properties where and when desired. The use of an adhesive or adhesive-like substance on the surface of the material provides an adhesion peel force after activation which is sufficient to form a barrier seal against a target surface at least as great as those of the material and the target surface such that perishable items, such as food items, may be effectively preserved. The storage wrap materials of the present invention may be utilized to enclose and protect a wide variety of items by various methods of application, including direct application to the desired item, enclosure of the desired item and securement to itself, and/or in combination with a semi-enclosed container.
Patent GB-733567-A (GB)
Title: Fibres, filaments and yarns from polyacrylonitrile
IPC: D01F6/18
Filed: 1953-01-01
Abstract: Artificial filaments or fibres are obtained by spinning a solution of an acrylonitrile polymer in dimethyl formamide containing a poly-functional methylol ether with at least three methylol ether groups, stretching the filaments so produced, and then subjecting the stretched filaments to a heat treatment so as to effect a cross-linking reaction between the methylol ether and the acrylonitrile polymer.  Filaments of improved tensile strength and elastic recovery are obtained.  The filaments have improved stability against heat.  The heat treatment may be effected at 100-140 DEG  C. The methylol ether may be an ether of tri-, tetra- or hexa-methylol melamine or other aminotriazine, or it may be a derivative of acetylene diureine such as the tetramethylol tetramethyl ether thereof.  In an example, a solution in dimethyl formamide of an inter-polymer of acrylonitrile with vinyl acetate is prepared, and to it there is added 5.7 per cent of hexamethylol melamine hexamethyl ether, calculated on the weight of the polymer.  The polymer has a molecular weight of about 96,000.  The solution is filtered, de-aerated, and extruded at 70-80 DEG  C. into a spinning funnel which is heated to 250 DEG  C.  Hot air is passed through the funnel to assist the evaporation of the solvent.  The filaments are wound on bobbins, and subsequently filaments from several bobbins are collected, twisted, and then stretched to eight times the original length by passing them over a hot polished metal surface heated to 170 DEG  C.  The filaments are then wound on to a bobbin and heated under tension at 120 DEG  C. for one hour.  The filaments so obtained and treated are no longer soluble in dimethyl formamide at 60 DEG  C. They have increased tensile strength in the cold and at elevated temperatures and have a higher modulus of elasticity as compared with similar filaments made from a spinning solution from which the hexamethylol melamine methyl ether was omitted.

Abstract: 1,102,771. Producing stereoregular polyvinyl alcohol fibres. MONSANTO CO. 8 April, 1965 [8 April, 1964], No. 14981/65. Heading B5B. Stereoregular polyvinyl alcohol filaments which are insoluble in boiling water are produced by wet or dry spinning a solution of a stereoregular polyvinyl ester of a halogenated acetic acid, in which all three hydrogen atoms of the methyl group in the acetic acid have been substituted by either chlorine or fluorine or by both fluorine and chlorine, and continuously hydrolysing the resulting filaments. The filaments are preferably formed by wet spinning, and the thus formed filaments, stretched, hydrolysed continuously, dried and hot drawn. The spinning solution may contain 12 to 40% by weight of the polyester dissolved in an organic oxygen-containing liquid and may be extruded into a coagulation liquid which is a non-solvent for the polymer but miscible with the spinning solution solvent. The filaments may be stretched immediately after hydrolysis. The organic oxygen containing liquid may be acetone, methyl ethyl ketone, tetrahydrofuran or dimethylacetamide. The coagulating bath may be aqueous. The filaments may be hydrolysed with a base having a pKb value less than 8À0, such as ammonium hydroxide, methanolic ammonia, tetramethyl ammonium hydroxide or a primary or secondary amine. The freshly extruded polyester filaments may be stretched at a draw ratio of 1À05 to 8À0 : 1À0 in a hot aqueous bath, and may be further stretched immediately after hydrolysis. They may then be dried by passing them over a roller maintained at a temperature of from 80‹ to 110‹ C. and finally drawn over a heated surface while stretching them at a stretch ratio of from 1À1 to 5À0 : 1À0. The ester spun may be vinyltrifluoro or chlorodofluoroacetate.

Abstract: 613,097. Brake and clutch control mechanism. OPPERMAN, S. E., and GANWICK ESTATES, Ltd. Jan. 7, 1947, No. 509. [Class 79 (v)] [Also in Group XXXIV] A control device for motor vehicles comprises a control member adapted to operate a clutch and a brake and a spring-controlled lever operable from outside the vehicle and adapted to be coupled to the control member in such manner that under the influence of the spring the clutch is disengaged and the brakes applied while manual operation of said lever results in freeing of the brake and engagement of the clutch. The invention may be applied to the type of vehicle described in Specification 613,092 and consists in the example shown of a pedal 10, Fig. 1, keyed to a shaft 9 carried in a bracket 8 which is secured to the vehicle body, and an arm 12 keyed to the shaft 9 and operating the brake rod 17 through a lost-motion device. On the pedal 10, Fig. 2, is a lug 13 carrying a clutch-operating cable 14 so that depression of the pedal 10 first disengages the clutch and then applies the brake. The pedal 10 is held in its uppermost position by means of a spring 15. Rotatably mounted on the bracket 8 is a sleeve carrying a hand lever 19 and an arm 20, Fig. 1, to which latter is connected a telescopic shaft and tube 22 and 23 secured to the vehicle casing 24 whilst a spring 25 urges the arm 20 downwards keeping the hand lever 19 in its rearmost position. To operate the clutch and brake mechanisms by the hand lever 19, the pedal 10 is depressed to its fullest extent and the lever 19 pushed forward so that a pawl 27 engages an abutment 31 on a quadrant 30 on the shaft 9. Further forward movement of the lever 19 will release the brake and engage the clutch. On releasing the lever 19 the spring 25 takes control, disengaging the clutch and applying the brake. By means of a trigger 29 the pawl 27 may be released from the abutment 31 and the brake and clutch become operable from the pedal 10.

Strengthening and supporting means for the coils may be provided, and the tubes may be of circular, rectangular or ovoidal cross-section, and may be pressed into shape after coiling. Narrow tubes may be used in the neighbourhood where greatest heat is generated, and broader tubes, or chamber-like members elsewhere. The tubes may be protected against corrosion by coating them with aluminium.
