Abstract: In connection with a device for casting lead grids for electric battery plates, a highly porous ceramic mold lining, preferably of zirconium oxide, is prepared by flame-spraying. Such a lining can include a thin surface coating on a profiled, basic metallic mold or a separately prepared insert plate which is retained to a metallic mold molder. The ceramic surface coating may be accurately formed in place, or may be formed as an over-spray which is then reduced in thickess. Formation of the surface coating may be accomplished by placing masks on the basic metallic mold during the flame spraying, for those areas of the grid which tend to accumulate material, or by adjusting an initially coarse profile of the ceramic layer to the exact profile of the casting by a material-removing treatment.

Abstract: A litterbox includes a rotatable enclosure having at least one access opening for a domestic animal and a rake disposed on its inner surface, a motor for selectably rotating the enclosure, and a receptacle disposed within the enclosure and movable between a first position generally against the inner surface of the enclosure, and a second position which is nearly vertically disposed within the enclosure. In operation, the receptacle is extended to an operative position, and the enclosure is rotated so that the rake will separate relatively large particles of solid excrement from the litter for deposit into the receptacle. The receptacle is then retracted to its initial, rest position. The litterbox may further operate to detect the presence of a domestic animal within the enclosure, and to initiate rotation of the enclosure when the domestic animal leaves the enclosure, to provide for fully automated operation of the litterbox.

Abstract: A cloned DNA sequence encoding T3 RNA polymerase is provided. This DNA can be inserted into an expression vector for recombinant expression of the peptide. The peptide can be used with dual promotor vectors containing T3 specific promoters.

The mold includes an upper mold to be closed over the lower mold, having a bent portion with a bottom surface which is to be a part of molding surface; and a middle mold to be placed between the upper mold and the lower mold, having a hollow region into which the bent portion of the upper mold is to be engaged when assembled.

Abstract: The transmitting and/or receiving antenna of an electronic article surveillance system utilizes a paired-lead loop configuration. One lead forms the active loop.The other lead forms a passive loop, which parallels and is mutually coupled to the active loop, but not conductively connected to it. This other lead is resistively loaded.The passive loop of the receiving antenna can also be used to conduct signals between the receiver circuitry and the alarm reporting devices associated with the receiver.

Abstract: An electronic article surveillance system which is capable of reliably identifying and discriminating between the different signatures of tags and labels which may come to pass in its vicinity, improving the reliability of the system and even permitting the tags and labels to be classified by type, and separately addressed, includes a receiver for detecting signals resulting from such tags or labels which incorporates improvements in its filtering and processing sections. A linear phase (constant group delay) filter is used to more effectively preserve the signal which is received, and thereby improve the signal which is ultimately delivered to the processor which follows.

Abstract: A passive infrared radiation (PIR) detection system permits data developed by the PIR detection system to be interpreted, to in essence "look into" a protected area and to positively determine the character of any images detected in the protected area. The system includes an array of PIR detectors for monitoring defined zones of the region to be protected. The array of PIR detectors is contained within an enclosure which is further provided with a lensing system which permits the several PIR detectors to monitor respectively assigned zones of the protected region from a single vantage point. The array of PIR detectors operates to develop a series of electrical signals which are then passed on for further processing and interpretation in accordance with various prescribed tests (criteria) which operate to distinguish between an intruder and other legitimate images capable of exciting the PIR detection system.

Abstract: A mold for skin covered foamed plastic molding which utilizes a middle mold to be placed between an upper mold and a lower mold, capable of avoiding an excessive amount of pressure to be exerted on the upper portion of the lower mold so that the durability of the lower mold can be improved, and preventing gaseous leakage so that the penetration of the liquid foam resin to be poured on a skin cover becomes controllable. The mold includes an upper mold to be closed over the lower mold, having extended side portions which can reach the base of the lower mold when assembled such that the extended side portions can support the upper mold by themselves.

Abstract: The stiffness of a flexible, substantially parallelepipedal container formed by shaping and welding a film which is made of a synthetic material and which is to enclose a liquid to be packaged, is improved by applying, before shaping, a second layer of a film formed of an identical or a different material, as a top film, to the surface of the film forming the container which does not subsequently come into contact with the liquid to be packaged. The top film includes a plurality of strips corresponding to the vertical surfaces of the final container which are welded to the film forming the container before shaping, along lines corresponding to the edges of the final parallelepipedal container.

Abstract: A stabilized support which is both small and light-weight in construction, and which receives the equipment with which it is used upon an expanded support network which deploys (positions) the supported equipment in a manner which alters the position of its center of gravity so that the resulting unit can be effectively supported at its center of gravity by an interrupted handle which includes a major portion which can be engaged for overall support and transport of the unit, and a minor portion which includes a control surface which is accessible by the operator's hand to achieve controlled orientation of the equipment support, separated by an appropriate device for providing mutual angular isolation between the two portions of the compound handle. The handle for the equipment support therefore provides all of the functions which are necessary for appropriate operation of the equipment which it supports, such as a portable video camera or the like.

Abstract: A mold for manufacturing a skin covered foamed plastic seat capable of structually preventing the leakage of the liquid foam resin from a space between the skin cover and the bossings provided on the mold for the holes to be made on it. The mold includes a lower mold over which a sink cover is to be placed, having a protruded portion to be inserted into a hole on the skin cover corresponding to a hole to be made on the skin covered foamed plastic seat, the protruded portion having a circumference smaller than that of the hole on the skin cover, and the upper mold to be assembled with the lower mold, having a bossing for making the hole to be made on the skin covered foamed plastic seat, the bossing having a concavity to be engaged with the protruded portion of the lower mold at a bottom, and a circumference larger than that of the hole on the skin cover.

An arrangement of tongues or wings extend from the sides of the spout so that a user may grip the tongue or wing while perforating the area of the bag within the spout upon insertion of the stopper.

Abstract: A locking apparatus which includes a locking element, an unlocking element, and a latching member. In the rest position, two arms of the latching member are maintained in their latched positions by compressed springs. To unlock, the unlocking element is turned in one or the other direction of rotation, whereby one of two inclined surfaces lifts one arm against the restoring force of a spring via a bearing surface of the unlocking element. Upon further turning of the unlocking element, an entraining projection from this element pulls the locking element along with it in the same direction of rotation. If the unlocking element is turned in the opposite direction, the arms automatically return to a rest position.

Abstract: A sorting device includes a plurality of shelves placed one above the other in a frame, each adapted to receive a printing plate in sorted fashion. Located in front of the insertion opening of the shelves is a transport device for moving the printing plates along the shelves, preferably from top to bottom. Between the transport device and the shelves is a sorting carriage which can travel along the shelves and which includes a pivotable flap which operates to deflect the printing plates from the transport device to a desired shelf. To allow the printing plates to be introduced into the shelves, while keeping the shelves placed close together, the shelves are pivotally mounted at their lower edges and the sorting carriage is provided with a tappet for engaging the shelf located above the selected shelf, to lift the upper shelves and thereby enlarge the insertion opening. The arrangement is especially suitable for sorting so-called "flexoplates" and flexible offset plates.

Abstract: Electronic article surveillance (EAS) tags are attached to articles of merchandise, not at the stores using EAS equipment, but in conjunction with the manufacture of these articles. At that stage, the tags are not detectable by the EAS equipment. They are made detectable upon receipt by an EAS-using store. For swept frequency RF EAS equipment, the tags are initially provided with two capacitors which make the tags resonant at a first frequency not detectable by the store's EAS equipment. To activate them, one capacitor is disabled, thereby making the tags resonant at a different frequency which is detectable.
