Abstract: The hand held circuit tester includes a hollow handle. A probe extends from one end of the handle. First and second leads extend from the other. An LED carrying circuit board is situated within the handle. One end of the circuit board is connected to the probe by a spring. The other end is connected to the leads. A "U" shaped collar is received within slots in the circuit board in a position perpendicular to the plane of the circuit board. The collar edge abuts the edge of one of the handle parts to stabilize the circuit board relative to the handle.

Abstract: Apparatus for adjusting the spatial relationship between the bottom and the back of a chair which may be subjected to severe mechanical stress, as in the case of a vehicle crash, the seat and the back being operatively connected respectively to two oppositely threaded portions of a rotatable shaft which is adapted to be rotated in one direction or the other to produce the desired change in spatial relationship, the arrangement providing the combination of exceptional strength in the event of a crash and reduced cost. The operative connection between the chair parts and the shaft includes two non-rotatable parts engaged respectively with the oppositely threaded shaft portions so as to move in and out with respect to the shaft as the latter is rotated, and a housing which permits those parts to thus move while preventing their rotation.

Abstract: The stuffed animal has a body covered by simulated fur material. First and second ears extend from the head in an upstanding manner. Each ear includes a mesh section adapted to receive the jewelry. The edges of the mesh section are covered by the simulated fur material. To increase the rigidity of the ears, each mesh section may be creased along its axis. The ears may be stitched together at a point spaced from the head. Reinforcing strips may be employed. The strips are enclosed by the simulated fur material along the edges of the ears.

Abstract: The handle defines a cavity retaining a power source and a source of illumination. The shaft, mounted on one end of the handle, has a channel extending from the handle and through the blade for guiding light down the shaft and out the blade to illuminate the area proximate the front of the blade. The blade is bifurcated, spaced tip portions being situated on either side of the channel.

Abstract: A strip of elastic is stretched over and encircles an object such as a door, car trunk or book cover. A tubular fabric cover may surround the strip. The cover is bunched so as to be capable of expanding lengthwise as the strip is stretched. A bow or other decoration, preferrably coordinated in appearance with the cover fabric, is removeably affixed to the band. One or more loops are formed in the band, preferrably proximate the bow, for hanging or mounting articles. The band may be continuous or may have a buckle to connect the ends.

Abstract: The vessel includes a fluid container or conduit. First and second magnets are situated on opposite sides of the vessel wall and are encircled by a metallic band or collar. The vessel may have an open mouth defined by a rim. In one embodiment, magnets are suspended by hangers form a rim of a cup. The cup and magnets are received in an exterior container with a removable lid. Other embodiments include oxygen tanks, oxygen tubes and containers for intravenous liquids.

Abstract: To reduce the force necessary to anchor the double "T" bar attachments, the filament of each attachment is made longer than the shortest (perpendicular) distance between the "T" bars to avoid the necessity of stretching the filament beyond its original length as it is dispensed. The filament lies in the same plane as the "T" bars to permit it to be fabricated on conventional stretching equipment. Preferrably, each end of the filament is formed at an acute angle relative to a line perpendicular to the "T" bar to which it is attached. The attachments can be supplied in continously connected ladder stock form or in a clip of parallel spaced attachments, situated between connector bars. In clip form, the attachments are fed along a correspondly shaped channel through the housing. In order to reduce the peak force necessary to sever the "T" bars from the respective connector bars, blades are located within the housing such that they cut at different times during the trigger stroke.

Abstract: An annular base carries a moveable cam member. Downwardly extending circumferentially arranged arcuate blades are mounted along the outer edge of the base to form a circle. Downwardly extending circumferentially arranged arcuate blades are pivotly mounted along the inner edge of the base to form a circle within the circle of fixed blades. Springs are interposed between radially aligned pairs of blades. The apparatus is positioned over the bagel such that the blades enter the interior of the bagel. The cam member cooperates with the moveable blades to move each blade in a substantially radial direction, against the intervening spring. The blades move from a position spaced from the aligned fixed blade to a position proximate to the aligned blade, as the cam member is moved, causing the dough to be pinched between the aligned blades. The dough is extracted as the apparatus is removed from the bagel.

Abstract: For connecting the spaced ends of underground irrigation or water pipe, a flexible replacement section with a rigid tubular coupling at each end is employed. Each coupling has an inner diameter equal to the outer diameter of the pipe being connected and is adapted to receive a pipe end therein. After one coupling is aligned with and mounted on one of the pipe ends, the replacement section is flexed so that the other coupling can be aligned with and mounted on the other pipe end as the flexed section is straightened.

Abstract: First and second oppositely oriented, spaced apart tandem printers are simultaneously computer controlled to print both sides of labels on a continuous web of blank labels. The front and back designs, the number of labels to be printed and the number of labels on the web between the printers are each entered into the computer and stored. The first printer is actuated to print label fronts and the web is advanced. The second printer is not actuated to print label backs until the first printer has printed the fronts of a number of labels equal to the number of labels between the printers. After the first printer has completed printing the fronts of the required number of labels, the second printer will continue printing an additional number of label backs equal to the number of labels between the printers. Sets of different labels can be printed sequentially.

Abstract: A casing seals to the edge of a mirror blank to form an autoclavable unit. An electrically energizable heater element is enclosed within the unit. The element is connected to a plug which extends from the casing and is adapted to engage a socket when the unit nests in a recess in a rack. A transformer is connected to the socket such that the heater is energized to preheat the unit while in the rack. Removal of the unit from the rack disconnects the electric supply, permitting the preheated unit to used without danger of shock. Several units may be preheated simultaneously on a single rack.

Abstract: A system for monitoring the occurrence of an event occurring with respect to an essentially metallic enclosure such as a truck body, e.g., the unwarranted opening of a locked door to the enclosure, which comprises a detector within the enclosure which senses the occurrence of the event and radiates a spread spectrum signal which is readily received by an external module mobile relative to the enclosure, so that the enclosure, at any time during its active life, may be externally interrogated to ascertain whether any such event has occurred, the enclosure optionally also containing a separate unit which records the spread spectrum signals for subsequent display and analysis, whereby the security status of the enclosure may be externally monitored at will, thereby to indicate whether or not the enclosure has been tampered with and, optionally, its security history--when and how frequently the event has occurred--may be retrieved.

Abstract: A substantially closed-loop system for use with a furnace wherein a fuel is burned and produces an off-gas, which system, by sensing appropriate parameters of the off-gas as it passes through the system, treats that off-gas in an optimized fashion in order to substantially eliminate the escape of contaminants and produce a substantial amount of useful by-products by one or more of (a) controlled treatment of the off-gas chemically and physically by employing a multi-flue compartmented and appropriately controlled treatment means, (b) the subsequent conversion of the essentially gaseous effluent from that treatment means into useful by-products, and (c) the subsequent conversion of the essentially non-gaseous effluent from the treatment chamber into useful by-products.

Abstract: Within a rigid housing cavity, freely moveably received members respectively support oppositely oriented spaced needles. Double "T" bar end type attachments situated between parallel connector bars are dispensed through the needles to attach buttons. Depressing protrusions accessible from the exterior of the housing moves the needle support members to alter the needle spacing to accomodate buttons with a variety of thread hole spacings. In order to reduce the peak force necessary to sever the attachments from the connector bars, the connector bars are severed from the ends of each attachment at slightly different times during the trigger stroke. A triangular linkage associated with the trigger provides a mechanical advantage which increases at an increasing rate, transmitting maximum force towards the end of the stroke, as the filament connecting the "T" bars stretches around the portion of the button between the thread holes.

Abstract: The relatively loose fiting external portion of the garment has a waistband. An internal shell is adapted to extend between the legs of the wearer from the front portion of the waistband to the rear portion of the waistband. The shell forms a snug fitting support for an absorbent pad which retains the pad in a position closely adjacent the body. The shell is preferably made of mesh-like elastic material. A liquid impermeable pouch may be attached to the shell to receive the pad in a removeable fashion.

Abstract: A negative resistance weightlifting apparatus suitable for use with, among other things, a weight in the form of a separate barbell, in which means under the direct control of the user controllably produces a negative resistance effect by pressing down with an adjustable force on the weight as it is being lowered and preferably positively disengaging itself from the weight when the latter is being lifted, safety means being provided to adjustably limit the weight locations where such force can be applied and to automatically release the excess downward force when the weight has achieved a predetermined and adjustable lower position, all to produce weight lifting and lowering excercises of maximum efficiency and effectiveness while at the same time protecting the user against accidents and any unfortunate consequences arising from temporary physical weakening.

Abstract: Significant reduction in the cost of fabrication of shallow junction, Schottky or similar semiconductor devices without sacrifice of functional characteristics, while at the same time achieving the advantages is achieved, after the non-polishing cleaning step is essentially performed, by subjecting the substrate to conditions which move disadvantageous factors within said substrate into a space substantially at said surface, followed by substantially removing said factor-containing space from said substrate chemical removal step, followed etching and vapor deposition steps. Although these new steps add time, and therefore cost, to the overall process, the devices under discussion when produced by known industry processes require yet more time, and involve yet more expense, so that the total process represents a substantial reduction in the cost of their manufacture while producing devices which are the equivalent or superior in electrical performance to such devices which are made by known industry processes.
