Abstract: This invention is an abdominal, and low back exercise machine used to tone and strengthen the muscles of the user. The machine includes a frame upon which a slidable foot rest or carriage and a seat are attached. The machine additionally includes a harness coupled to the carriage through a strap such that as the harness moves in a first direction, the carriage moves in the opposite second direction along the frame. The harness is placed around the shoulders and neck of the user such that when the user sits on the seat and brings the shoulders towards the knees, the legs will be drawn up to the shoulders by the movement of the carriage. This exercise device strengthens the user's upper and lower abdominal muscles. The machine further includes an exercise ball which supports the back or stomach while performing hyper-extension type exercises.
Abstract: A formable plastic product which may be manually shaped into various ornamental devices includes a tubular plastic sheath normally having a predetermined orientation and configuration and tending to retain that orientation and configuration absent external force varying such orientation and configuration. Received in the interior passageway of the sheath is a forming member which extends essentially the length of said sheath, the forming member including an outer surface portion which is unbonded to the sheath and spaced from intimate contact with the internal passageway of the sheath. The forming member is further characterized as being manually formable to a desired conformational shape and for retaining said desired conformational shape whereby said sheath assumes the conformational shape of said forming member as contrasted to the predetermined orientation and configuration of said tubular sheath.
Abstract: A plastic T-shirt bag pack in which the outer walls of adjacent bags have been corona-treated and each bag is provided with a central rack mounting tab with a pair of angled lines coming together in an apex adjacent the upper edge of the central tab, the lines being readily severable when the tab is placed on the central mounting element of a conventional rack. At their opposite ends the lines are curled inwardly toward each other to prevent their tearing from propagating down into the bag walls. This may be further prevented by providing a sinusoidal cut below the lower extremities of the angled lines. The area between the apex and upper edge of the tab is provided with a tear start so that when the bag is pulled from the rack, the area is severed to permit removal of the tab with the bag. Appropriately disposed pressure points with the corona treatment above, enable the bags of the pack to be self-opening.
Abstract: Method of making gusseted plastic bags in either rolls or stack packs, each bag having at least one plastic promotional strip extending along a side edge of the bag and secured adjacent to top and bottom edges. The promotional strip may be disposed either between the folded bag edges forming the gusset or outside of the gusset, and may or may not be perforated.
Abstract: The invention encompasses a system by which a leading T-shirt bag may be removed from a rack while initiating the opening of the bag mouth of the next ensuing T-shirt bag, but without also simultaneously pulling out and opening in succession subsequent T-shirt bags of the pack. The invention accomplishes this by modifying the form of the conventional T-shirt bag by placing a second lower slightly offset horizontal tear slot below the horizontal slot on the center mounting tab by which the tab is held on the hook of the dispensing rack. The offset slot creates a narrow bridge on one end and a wider bridge on the other end of the slot. A glue spot is provided offset from the center toward the side with the narrower bridge, between the back of the forward bag and the front of the subsequent bag. When the leading T-shirt bag is filled and subsequently pulled away, the wider bridge first ruptures and the narrower bridge, coupled with the offset glue spot, works to pull open only the next bag.
Abstract: A head covering with eye spraying capability is described. A hard-hat like device incorporates a liquid spraying system between the layers of the head covering for use in environments in which the user may be subject to dirt or dust entering his eyes while working. The invention consists of a digitally activated pump connected by tubing to a reservoir containing water or special eye washing fluid. The reservoir is connected by tubing to one or more spray heads mounted on malleable tubing adjacent the user's face. The tubing supporting the spray heads may be changeably fixed by the user to provide accurate spraying into the user's eyes. A series of one way valves permit air to be replaced in the pump after activation while pressurizing the reservoir and forcing fluid out of the reservoir and through the spray heads and into the user's eyes.
Abstract: A pack of registering plastic T-shirt bags in which the walls of each bag are provided with registering central tabs projecting into the bag mouth, the tabs each having a rack retainer mounting orifice comprising a lower transverse cut portion extending between points spaced inwardly from the side edges of the tab with one end of the cut portion curving back and upwardly to extend toward, but terminating before reaching, the upper edge of the tab; and the other end of the cut portion also curving back upwardly and terminating in a segment of the cut extending back parallel to the lower transverse portion for a distance less than half the extent of said latter portion; thereby, the tabs of the bags may be mounted on a rack retainer by passing the retainer through the lower transverse cut portion of the mounting orifice.

Abstract: A spinner toy comprised of an elongated wire element looped back upon itself at its center and twisted to form a straight helical member, one end of which is the center loop and the other end of which is bent back upon itself and disposed in a plane passing through the member, with a first element slideably disposed on the straight member in abutment with the looped end. A spinner, formed by a pair of polyester film strips is disposed on the member angularly displaced apart from each other, each strip having first and second ends and being doubled back at a single intermediate orificed apex to bring its ends together with their orifices in register and secured together by an eyelet through which, and through the apex orifices, the member is passed, with a sleeve interposed and extending part way between the eyelet and the apex orifices, and a square plate between the eyelet and the sleeve.
Abstract: Apparatus for skin packaging articles on a backing card in which a heating unit for film is disposed behind a work table having a vacuum platen on which may be placed a backing card with an article to be packaged; and, upon activation, is moved vertically between a first position above the level of the table and a second position not higher than the table level. A film clamping frame holds a section of film closely above the heating unit when it is in its first position, and when the unit is moved to its second position, moves the heated clamped film section forward and downward onto a backing card where it is drawn down tightly against the article on the card upon creation of a vacuum. Upon completion of the packaging, the backing card is pulled forwardly off the table and its film is severed from the further film which is pulled with it, such further film then being clamped on the film clamping frame which is moved back up to its elevated position for repetition of the cycle.
Abstract: A flexible cryogenic hose is comprised of an inner cryogenic tube surrounded by a concentric heat shield, a closed concentric chamber and an outer protective jacket. At normal ambient temperatures the chamber is completely filled with carbon dioxide gas. As cryogenic liquid is pumped through the inner cryogenic tube, heat is transferred from all structures within the hose, including in particular the carbon dioxide gas in the closed chamber, which runs the length of the cryogenic tube. As the carbon dioxide gas is cooled, it liquefies, thereby substantially evacuating the chamber. The chamber has sufficient structural rigidity to avoid collapse at normal atmospheric pressures. After the cryogenic hose is used, cryogenic flow ceases and the hose warms. In warming, carbon dioxide gas in the chamber gassifies and again refills the chamber.

Abstract: An improvement is made in an externally driven gun having an ammunition feeder capable of providing at least two types of ammunition to the gun by incorporating a gear transmission into the driving mechanism coupled to the ammunition feeder to appropriately control an in-feed sprocket within the ammunition feeder so that the ammunition type can be changed prior to commitment of the previously selected type of ammunition to the firing mechanism of the gun. The gear transmission which is coupled to the in-feed sprocket provides acceleration to the sprocket at the last possible moment prior to handing-off the round to the firing mechanism. In one embodiment the gear transmission includes a cam follower rotatably coupled about an offset axis to the input shaft and coupled to the output shaft through a radial slot. The cam follower is rotated by means of a stationary cam race as the follower itself is rotated as a whole by the input shaft.
Abstract: A high volume cryogen vaporizer includes a radiator where a working fluid draws heat from ambient air for vaporizing a cryogen in a heat exchanger. An electrical heater is provided for periodically heating the working fluid to defrost the radiator, thereby allowing sustained operation of the vaporizer. When not required for defrosting the radiator, the heater may be operated to heat a working fluid in a circuit separate from that of the radiator, and in which the heated working fluid is used for further elevating the temperature of the vaporized cryogen in a second heat exchanger, thereby making possible a gas output temperature higher than ambient air temperature.

Abstract: An improved radioimmunoassey procedure involves the use of an improved reusable immunoadsorbent through which a sample of an antigen and radioactive labelled antigen is flowed to form a bound and unbound fraction. The bound fraction is releasably coupled to the immunoadsorbent which includes a solid particulate substrate to which antibodies, specific to the antigen, are covalently bonded by reaction between the carboxyl or amine group of the antibody and a group such as an acyl azide, carbonate, thiocarbonate, polythiol, isocyanate, epoxide and chlorothioformate group, for example, reacted on the substrate. The substrate includes a porous refractory material having at least one polymeric material bonded thereto as a barrier and to which is linked one of the above groups for reaction with the carboxyl or amine group of the antibody. The antigen bound to the immunoadsorbent is stoichiometrically released by an eluting solvent and the immunoadsorbent is reused.
Abstract: Automated radioimmunoassay directly from serum, for those antigens present in serum in relatively small amounts, is accomplished by use of an immobilized immunoadsorbent having an excess of antibodies, specific to the antigen, covalently bonded to a particulate substrate. The serum is diluted and preincubated in the presence of a radioactive labelled antigen and an antibody specific to the antigen. The preincubated mixture is flowed through the immobilized immunoadsorbent and the labelled and unlabelled antigen not bound to the antibody in preincubation are bound to the immobilized immunoadsorbent while the labelled and unlabelled antigen bound to the antibody during preincubation flow through the immunoadsorbent. An eluting solution is flowed through the immunoadsorbent to release the antigens bound thereto for reuse of the immunoadsorbent.
