Abstract: A novel implementation of a tape automated bonding process of attaching leads to a semiconductor die is disclosed which utilizes a method of attaching tape leads which extend across the interior surface of the die rather than radially outwardly from the die. Two-layer or three-layer tape construction is used, with the insulation being located between the top of the die and the leads. This technique enables lead placement on opposite sides of the die in interdigitated fashion, allowing die to be installed on a circuit board more closely adjacent than has previously been possible.

Abstract: The computer paper tab stripper has an elongated preferably generally rectangular block with a flat bottom, preferably with a non-slip rubber tread or the like, a flat top spaced above the bottom and interconnecting two opposite sidewalls and two opposite endwalls. Preferably, the length of stripper is slightly less than that of a computer paper to be stripped of its tab so that the tab ends stick out of opposite ends of the stripper and are easy to grip. One of the sidewalls is sloped to form a side ramp of preferably about incline 45.degree. to enable the computer paper to be slid up the ramp easily and over a spaced array of vertical pins in the top, which pins are adapted to fit through openings in the computer paper tab. The pins preferably include a truncated cone portion. An elongated preferably rectangular top lid is hinged to the top of the block on the side opposite the ramp and is adapted to move between a lid-up position and a lid-down position.

Instead of a single second strip, one can use a plurality of second strips which bridge the tabs on opposite sides of the first strip.

Abstract: The golf shaft guard includes a hollow foamed, spongy elastomeric tube with a generally central space extending the length thereof into which a non-metallic golf club shaft is inserted through a side slit running the length of the tube. The space preferably is dimensioned relative to the shaft so that the tube walls defining the space grip the shaft, holding the tube in place against the hosel of a golf club bearing the shaft. In one embodiment, the space is uniform in diameter, while the club shaft tapers down from its end grip to the hosel. In another embodiment, the tube and space are expanded to provide a head into which the head of the golf club is inserted for protection, the tube thus covering the head, hosel and shaft, the latter preferably throughout most of the length thereof. Thus, the invention includes the assembly of the golf club and guard.

Abstract: An improvement is provided in an electromagnetic door lock device. The device itself includes an electromagnet in a housing adapted to be connected to the top of a door frame and depend from the underside thereof above a door in the frame. The device also includes an armature block connected to the top of the door in a position near the electromagnet. The armature moves between a down inoperative position away from the electromagnet, facilitated by gravity, when the electromagnet is deenergized and an up extended operative position against the underside of the electromagnet housing when the electromagnet is energized. A locking plate connected to the housing has a tab which depends therefrom and abuts the armature when the latter is in the up position to lock the door closed in the door frame. The improvement prevents slow separation of the armature and tab and hesitant unlocking of the door when the electromagnet is deenergized.

Abstract: The improvement is in an electromagnetic door lock device which is connected to the underside of the top of a door frame. An armature is attracted to the energized electromagnet and is connected to the top of the door for movement between a resting unlocked position directly on top of the door and an upwardly extending locked position adjacent the underside of the energized electromagnet. The armature which has a protrusion extending from one or both of the two opposite sides and the electromagnet carries one or a pair of tab plates connected to one or both of the opposite ends of the electromagnet and having a depending tab which intercepts the armature only when the latter is in the upwardly extended position, so as to lock the door shut.

Abstract: The improvement as in an electromagnetic door lock device. The device includes an electromagnet which is secured to the underside of the top of door frame, and an armature connected to the top of a door hinged in the frame. The armature moves between a resting unlocked down position and a locking position in which the armature extends up toward the electromagnet being attracted thereto. When in that attracted position, the armature is intercepted by one or more tab plates depending from one or both of the opposite sides of the electromagnet so that the door cannot be opened. Deenergizing the electromagnet causes the armature to fall down to the unlocked position. The improvement includes a protrusion from one or both of the opposite sides of the armature, which protrusion fits within a notch on the underside of the tab plate to lock these two parts together. The tab plate may have adjustment slots for aligning the notch and protrusion.

Abstract: An improvement in an electromagnetic door device. The door device includes an electromagnet secured in a housing to the underside of the top of a door frame, a door hinged in the frame for opening and closing therein, and an armature secured to the top of the door for movement betrween a resting position on the door top and an operative position upwardly magnetically attracted to the electromagnet when the latter is energized. In the operative position, the armature is intercepted by a locking plate depending from the housing, so as to lock the door until the electromagnet is deenergized and the armature drops away to the resting position. The improvement is a device which biases the armature upwardly so that it is, in effect, lighter, requiring less electromagnetic force to attract it and permitting the armature to be spaced, in the resting position, a greater distance therefrom for improved door-frame clearance.

Abstract: A document shredder comprises a pair of cutter assemblies, each having a shaft on which there are cutter disks with interspersed spacers. The disks overlap to form a nip. On the one shaft, additionally, there are rings mounted in the spacers, and that permits the shaft to be axially compressed tighter than the shaft without rings. This provides for relative flexibility and axial movement between the shafts such that foreign objects can more easily be removed. A 20 inch cutter assembly driven by a single phase motor through a planetary gear system is provided.

The weld line is part of the smooth level outer surface of the windscreen. The inner surface of the windscreen is preferably covered by a wind noise attenuation medium such as a fabric formed of an outer layer of napped nylon, an intermediate layer of polymeric plastic foam and an inner layer of woven nylon.

Abstract: A device for use as a convenient, easy-to-use, and inexpensive pump for pumping water is disclosed which uses water pressure from a standard garden hose connected from a tap to the pump apparatus as the motive power to pump between seven and eleven times the volume of the water from the garden hose from a reservoir into a discharge hose which is any of several different standard sizes and which is connected to the pump apparatus. The water from the garden hose flows into the pump through a pump inlet having a reduced diameter venturi, which increases the velocity of the water, into a pumping chamber with the resulting drop in pressure creating a vacuum in the pumping chamber. The vacuum in the pressure chamber draws water from a reservoir the pump is placed in through a reservoir inlet chamber into the pumping chamber in the pump body, and the water exits the pumping chamber through a pump outlet located on the opposite side of the pumping chamber from the pump inlet.

Abstract: The water purification device includes a hollow casing split into a pair of mating sections releasably connected together for easy access to the inside of the casing. A water pipe is disposed in the casing, extends out opposite ends thereof and bears connectors for connection to water-bearing plumbing and the like. A non-rotating removable and replaceable water impeller having a spaced number of blade segments is disposed longitudinally on the water pipe to control mixing and the residence time of water passing through the pipe. The impeller can be in the form of a single helix or in the form of a flexible accordion-pleated band which is longitudinally urgeable between a collapsed and an extended position to control the number and pitch of the blade segments or pleats in a selected portion of the pipe. That selected portion is disposed in an electromagnetic coil in the casing, which coil, when energized, causes sediment in the water to dissolve and pulverize.

Abstract: A brassiere strap retainer includes a first strip of Velcro material bearing hooks on one side thereof, and a second strip of Velcro material having a hook-receiving pad on one side thereof. The pad of the second strip faces the hooks and one end of the pad strip is secured to the hook-bearing strip, as by glue, sewing or the like. In one embodiment, the pad-bearing strip is shorter in length than the hook-bearing strip and is positioned thereagainst so as to expose both opposite ends of the hook-bearing side of the hook strip. The pad-bearing strip forms an openable flap, between which flap and the adjacent hook-bearing strip surface a brassiere strap can be releasably trapped. The exposed hook portions of the strip are used to releasably anchor the strap to the interior of a woman's upper garment so as to conceal the strap. In another embodiment, one end of the pad-bearing strip is secured to one end of the hook-bearing strip so that the two strips extend away from each other.
