Abstract: A coil toop type cable tie of one-piece molded plastic construction having a flexible strap and a fastening head at one end thereof. The fastening has a passageway running parallel to the strap and a hinged pawl extending into the passageway and having at least one tooth adapted to mesh with ratchet teeth on one side of the strap. The hinged pawl is connected to the fastening head by hinge which defines the closed end of a notch separating the hinged pawl from the rest of the fastening head. The notch opens onto a surface of the hinged pawl opposite to the surface on which its tooth or teeth are formed and preferably angles from its closed end to its open end generally toward the strap.

Abstract: Keyless lockable security devices in the form of a padlock or clevis pin for use in securing bulk containers in which the devices consist of a body member having at least one blind bore therein and a male member having limbs corresponding to the number of blind bores, insertable in the bore or bores.Each of the bores and the limbs have an annular recessed portion of substantially crochet hook form and an annular member of spring steel split cross-sectionally in the form of a C-ring is located in the recessed portion of the body member.The male limb is driven into the bore until its recessed portion is engaged by the annular member to prevent withdrawal of the limb from the bore.

Abstract: A binding strap suitable for use as indication tag for various purposes is provided.The binding strap is made of a synthetic resin in a body and has a folding portion at the center, a hole with fastening pieces at one side and a projection to be inserted and fastened in the hole at another side.The binding strap of the present invention may be easily and certainly attached to an article at one touch with an empty hand by thrusting it through an opening of the article, folding it and inserting the projection into the hole. The binding strap of the present invention has a guide fluke at the end portion in order to easily thrust it through an opening of an article.

Abstract: A device for attaching or affixing one article to another, or for bundling and holding articles together. The device is formed by a filamentary member having a shielded pronged socket at one end and a head at the other end. The head is insertable into the socket and is proportioned to forestall accidental or deliberate distortion of the socket, and consequent release of the head, after it has been locked in position by the prongs of the socket. The prongs desirably include appendages to enhance the locking effect.

Abstract: A tamper proof seal comprising a tie member makes a seal with a coupling seal on a plug which is movable laterally into the seal body portion while said tie member is movable into said body portion perpendicularly to the movement of said plug, said tie member, said seal body portion and said plug capable of being molded out of a plastic material as a unit.

Abstract: This invention relates to a device for heat-insulating the top part of the annular space separating the main vessel from the safety vessel from a fast-neutron nuclear reactor, the two vessels having a common vertical axis and being open at their top part and covered by a horizontal slab in which the ends are fitted so as to be suspended by the slab.According to the invention a substantially cylindrical heat-insulating ring is mounted under the slab and cooperates with the slab and with the facing walls of the vessel to bound the region to be insulated. The ring extends through the annular space in a horizontal plane and is carried by the slab by means of tie-rods, and a top insulating ring divided into two coaxial elements rests on the bottom ring and is secured to the walls of the two vessels respectively by an assembly of spacing springs disposed radially and bearing against the two elements.

Abstract: Polythene bags are used to group together articles of clothing for transit. The invention relates to a security seal for use with such bags to prevent undetected transit theft. The seal according to the invention has two strip-like portions, which are formed with latching portions at points along the lengths of the strip-like portions. The seal is applied to the neck of the polythene bag, and during application the latching portions pierce the bag and pass through to engage in pairs with latching portions on the other strip-like portion. The latching portions have a weakened section, which breaks if the latching portions are urged out of engagement, thus a bag once sealed cannot be opened undamaged, as the seal will have broken latching portions indicating to a checker at the destination that the bag has been interfered with.

Abstract: A security seal formed of molded plastic which is particularly adaped for use with articles closed by staples and hasps, such as are used on a strap closing the neck of a mail bag. The seal components are arranged so that the loop formed by the assembled seal strap may be tightened to a predetermined dimension and no smaller, with the tightening tension not being applied to the point at which the seal is designed to rupture. A finger loop is provided which extends from the loop formed by the assembled seal in such a manner that when the finger loop is pulled, tension is applied directly to the designed rupture point to facilitate removal of the seal.

Abstract: A snap ring lock which utilizes a bolt or cable that can be extended through hasps and which has a locking portion formed with tapered grooves spaced predetermined distances apart and receivable in a cylindrical member having a plurality of snap rings spaced therein at predetermined distance which distance is different from the distance between the grooves of the bolt to provide a seal which can be locked in a number of positions to adjust to the particular requirements. In a modification the bolt may carry the snap rings and the grooves may be formed internally within the locking member and identification can be placed on the bolt.

Abstract: A keyless padlock seal for shipping containers, highway trailers, railroad box cars and the like, comprising a lock body and a hasp which is spring-locked to said lock body. The hasp cannot be removed from the body without destruction of either the hasp or the body. A code-marked seal may be provided on the lock body and secured thereto in such manner that it cannot be removed or replaced without at least partial destruction of the padlock and evidence of tampering.

Abstract: Disclosed is a plastic sealing device comprising a hollow, bottomless cubic body and a sealing strip integrally connected to and extending from said cubic body. The sealing strip has an arrowhead-shaped end, and in use, the arrowhead-shaped end of the strip is inserted in the slits of the hollow cubic body, and is pulled out of the cubic body, thus passing therethrough and closing the open bottom of the cubic body. After passing through the apertures of an object to be sealed, the arrowhead of the strip is inserted in a slit in the top plate of the cubic body until it is caught by catch means within the cubic body. The structure of the sealing device is conveniently amenable to plastic injection moulding and mass-production.

Abstract: A disposable padlock which cannot be opened by a key but whose locking effect can only be nullified by the use of sufficient force to deform the padlock. A shackle is automatically engaged when inserted into a body portion of the padlock. Engagement members mounted in the body portion are biassed to engage recesses in limbs of the shackle in such a way that the padlock will deform before the shackle will be removed by the application of force. Means may be provided for preventing rotation of the limbs of a sheared shackle engaged by the body portion.
