摘要:
An air-scenting device, which can be mounted vertically, horizontally or at any orientation, including upside down, without any leakage or dripping is disclosed in which there is no free-to-flow fluid under gravitational force, thus causing no spillage at any orientation. The device comprises a barrel containing an open-cell porous mass which contains air-scenting liquid within its pores and a porous wick surrounded by a cage, having perforations, and allowing evaporation of air-scenting fluid transferred to it by capillary action.

A breathing mask with debris deflector features small debris deflectors that close the gaps between the bottom profile of the eyewear worn by the user and the mask face-contacting perimeter. The debris deflectors are positioned, oriented and profiled to prevent fine debris from reaching and harming the eyes of the mask wearer without interfering with the field of vision of the wearer or causing visual glare.

A method for controlling distribution and access to an information product, said method comprising the steps of: superposing a utility-reducing masking effect on said information product; controlling the presence, absence and/or permanence of said masking effects by the outcome of an interactive communication between a provider and a receiver of said information product. The term information product includes books, video recordings, audio recordings, music, images and multimedia works. The masking effects described in the present invention are of a generally interfering nature and can be superposed on the information object as an overlay, interruption, interference, discontinuity, disturbance or disorientation. The purpose of imposing a masking effect is to derive a masked version of the information product for preview purposes that can be readily distributed to interested customers in an unrestricted manner. The masking effect is removable after conditions for purchase and/or other authorization criteria are met.

A braided fiber reinforced thermoplastic member is formed by a device, which comprises a braiding device for weaving thermoplastic coated fibers with second fibers onto a weaving mandrel for form a braided preform, and a heating die for melting the thermoplastic of the coated fibers of the braided preform to form a continuous matrix of thermoplastic between the coated fibers and the second fibers. A method for forming a fiber reinforced thermoplastic member comprises coating carbon fibers with a thermoplastic melt, cooling the thermoplastic coated carbon fibers, braiding the coated carbon fibers onto a weaving mandrel with Kevlar.RTM. bias fibers to form a braided preform, and drawing the braided preform through a heating die.

A face mask is disclosed that can be reusable or disposable, and which filters particulate matter and noxious and poisonous gasses from breathed air. The mask has a mask shell that is thermoformed of cross-linked, closed-cell foam sheet that is impermeable to air while having good shape retention and elasticity. The mask shell is perforated with multiple holes in its central area to permit inhaled air to pass through the otherwise impermeable shell. This mask shell is stiff enough to support filter liners made of, for example, an activated charcoal impregnated fibrous sheet that covers the holes and is retained to the inside and/or the outside of the mask shell by a retainer which is easily removed to replace the filter liner(s). Alternatively, the filter liner(s) may be bonded to the inside and/or the outside surface of the foam mask shell to make a disposable mask. A one-way valve is mounted through the wall of the mask shell to exhaust exhaled air.

The present invention provides a device for fixedly securing a cap and body of a capsule together to thereby render the capsule tamper evident. In one form of the invention, the capsules are conveyed at spaced intervals along a predetermined path of travel through a treatment zone which is generally perpendicular to the longitudinal axis of the capsule. An elongated bar having a tapered edge and positioned within the treatment zone engages the side of the capsule to produce an indentation in the side of the capsule which increases in depth from the entry and to the exit end of the treatment zone. This indentation around the capsule hermetically seals the cap and body of the capsule together so that the cap and body cannot be separated without destruction of the capsule. In another form of the invention, the bar is increasingly heated along its length so that, in addition to forming an indentation circumferentially around the capsule, simultaneously hermetically seals the capsule cap and body together. In still another form of the invention, a rotating disc having an outer shaped edge is aligned to and frictionally engages the outer periphery of the capsule in order to produce the desired indentation in the capsule. The disc can be heated to produce a fluid (hermetic) seal between the capsule cap and body. In still another form of the invention, a two part heated embosser forms an indentation around the capsule. The capsule is then rotated and again engaged by the embosser to hermetically seal the capsule.

A face mask is disclosed that can be reusable or disposable, and which filters particulate matter and/or noxious or poisonous gasses from breathed air. The mask has a shell that is formed of polymeric closed cell foam that is impermeable to air while having good shape retention that enables the edge of the mask shell to conform and seal to the face of a wearer around their nose and mouth. The foam mask shell has one or more holes through the central portion thereof and a filter is mounted to cover said hole(s) to thereby filter all inhaled air passing through said holes. A one-way valve is mounted through the wall of the mask shell to exhaust exhaled air.
摘要:
A method for sealing an assembled gelatine capsule of the type used to contain and dispense medication is disclosed. An assembled capsule the axis of which is oriented perpendicular to the axis of a thin elongated bar is moved along and in contact with a thin edge of the elongated bar. The surface of the assembled capsule, at a point where the cap and body of the capsule overlie each other, is initially in contact with the thin edge of one end of the bar and the capsule is moved along the length of said bar so that the axis of the capsule moves closer to the edge of the bar. The bar is heated so as to be at a first temperature at a first point between its ends that will melt the gelatine, and the remainder of the bar is at a temperature that will heat plasticize the gelatine. As the capsule is moved along the heated bar it is rotated either by friction between the bar and the capsule or by mechanical means. The result is that a circumferential indentation is created around the capsule where the cap and body overlie each other, and the cap and body are fused to each other creating a hermetic seal. When a hermetric seal is not desired the temperature at the first point is below the melting temperature of the gelatine. The formed indentation and the hermetic seal, singly and combinationally, cooperate such that any attempt to separate the cap and body of a sealed capsule will fracture the cap and/or body and thereby provide an indication that the sealed capsule has been tampered with.
