A method for creating peelable or frangible seals comprising the steps of: 1) selecting a first planar film with a polyethylene based resin disposed on its surface; 2) defining a frangible sealing zone on a surface of the first planar film; 3) heat sealing a second planar film to the frangible zone where the second planar film has a seal surface comprising a plurality of polymers; and 4) cooling the first and second planar films and frangible zone. A seal is created whereby peeling away the second planar film causes a rupture in the polymers disposed on the second planar film's surface.

The invention relates to a clamping drill chuck including a chuck body (1), a clamping cone (2) that can be rotated coaxially in relation to the chuck body (1) and is axially supported on a jaw holder (3) mounted on the chuck body (1) and in which clamping jaws (4) are guided in guiding slits, said clamping jaws being adjustable, by means of the jaw holder (3), for the clamping and releasing action by a relative rotation between the chuck body (1) and the clamping cone (2). The drill chuck also includes a locking device (9) provided with a toothed ring (6) which is coaxial to the chick axle (5), in addition to a latch mechanism (8) which is mounted on the jaw holder (3) and engages in the toothed ring (6) when subjected to the force of a spring (7).

An improved multi layered frangible seal is bonded over the pour spout opening of flexible plastic bottle containers of the type used for storing and dispensing pourable products such as motor oil or transmission fluid and the like. The seal provides a leak proof closure that is only strong enough to remain intact when subjected to the pressure created by the weight of the liquid contents when the filled uncapped container is held in an inverted position. At the same time the seal is also weak enough to break open and dispense the contents when a set amount of additional pressure is brought to bear against the seal by a consumer squeezing the inverted container. The seal allows the pour spout of the inverted container to be inserted into the fill opening while remaining intact which prevents any spilling of the contents. The seal is then broken open by the consumer squeezing the flexible bottle which dispenses the contents into the fill opening thereby eliminating the need for a fill funnel. The seal invention is constructed of a first layer of leak proof frangible material that is bonded to an additional layer of material. The additional layer of material contains one or more cut through and / or cut out void configurations forming a breaking pattern that turns the additional layer into a break and tear template layer. Bonding the template layer to the frangible layer strengthens the surface area of the frangible layer every where except in the area of the breaking pattern by leaving only the first frangible layer covering over the cut through and / or cut out void configuration forming the breaking pattern. This leaves a weakness in the multi layered seal only in the area of the breaking pattern which forces the seal to break open and tear only in the weaker single layered area of the breaking pattern configuration when sufficient pressure is brought to bear against the seal by a consumer squeezing the inverted container. The use of a separate layer of material to form the frangible area of the seal provides the ability to accurately control the thickness of the seal material that must break open, thus allowing the burst pressure of the seal to be precisely set. An uncut area of the breaking pattern forms a connector that keeps the broken open portion of the seal attached to the annular portion of the seal remaining bonded to the pour spout rim thus preventing any contamination of the dispensed contents when the seal breaks open.

The present invention relates to an apparatus and a method for protecting the copyright of an information signal recorded on a recording medium such as a DVD (Digital Video Disc) for presenting the signal to the user or an information signal transmitted through transmission media such as the Internet and for preventing an illegal copy of such an information signal.

The subject disclosure presents systems and methods for automatically selecting meaningful regions on a whole-slide image and performing quality control on the resulting collection of FOVs. Density maps may be generated quantifying the local density of detection results. The heat maps as well as combinations of maps (such as a local sum, ratio, etc.) may be provided as input into an automated FOV selection operation. The selection operation may select regions of each heat map that represent extreme and average representative regions, based on one or more rules. One or more rules may be defined in order to generate the list of candidate FOVs. The rules may generally be formulated such that FOVs chosen for quality control are the ones that require the most scrutiny and will benefit the most from an assessment by an expert observer.
