Abstract: ABSTRACT OF THE DISCLOSURE            Apparatus to be used for exercising the limbs, and particularly the legs.  The apparatus includes a support upon which a person lies with his legs extending beyond an end thereof and resting on a pair of operating bars.  Each bar projects from beneath the support and has at its inner end beneath the support a cam mounted to rotate around a central point, these central points being located appro-ximately in line with the hip joints of the person on the support.  A resistance in the form of a weight is connected by a flexible connector to each cam so that when the user's legs are spread apart to move the operating bars in the same direction, this movement is resisted by weight. By adjusting the connections of the flexible connectors to the cams, the weight can be made to resist the movement of the bars towards each other.  The length of the strokes or movements of the operator bars away from or towards each other is adjusted by adjusting the connection of the flexible con-nectors to the cams.

Abstract: Abstract:                   The present invention relates to an improved resistance welding pin having a tubular shank throughout the major portion of its body, the distal end of the shank defining a sharpened tip which is arcuate in section and preferably having a similar radius of curvature as that of the remainder of the shank.  By virtue of the tubular and preferably circular configuration of the shank, the heat of welding is more efficiently utilized, a greater amount of melting of metal being effected with a given amount of welding current than is the case with welding pins having conventional shanks, e. g. of flat or arcuate configuration.  By reason of the reduced welding time required to effect a firm connection between the pin and the metal substrate, there is reduced danger of damage to the materials adjacent the welding pin.

Abstract: Abstract of the Disclosure The disclosed article (e.g. a sanitary napkin) typically comprises (1) an elongated absorbent pad, (2) an outer covering layer in adherent contact with at least one surface of the pad, (3) an adhesive strip or layer on the exposed surface of the outer layer, and (4) a release liner for protecting the adhe-sive layer.  The adhesive layer is useful for removably attach-ing the article to the inside of an undergarment or the like. Production of the article can be greatly simplified by using a hot-melt pressure sensitive adhesive (PSA) as the adhesive layer.  However, the rubbery base for the hot-melt PSA should be very carefully selected.  Two types of rubbery polymers pro-vide good results, i.e. (a) an A-B-A block copolymer having polystyrene end blocks and a rubbery poly(ethylene-butylene) midblock and (b) a radial teleblock copolymer with branches having polystyrene terminal blocks and a butadiene segment in the center.  One or both of these rubbery polymers is used to formulate the hot-melt PSA along with a suitable tackifier and a process oil.

Abstract: ABSTRACT OF THE DISCLOSURE        A sheeter for feeding sheets in shingled relation to a point of collection including a source of sheets, a first conveyor belt and a second conveyor belt operating at substantially reduced speed so that the sheets are collected thereon in shingled relation. For snubbing the successive sheets so that they are decelerated and uniformly spaced on the second conveyor belt, a snubber is provided in the form of a knock-down roller arm rotating in a vertical plane at the upstream end of the second conveyor belt and so spaced therefrom as to press a sheet into engagement with the second conveyor belt, the arm being driven at a rotary speed which is synchronized with the source, with means being provided for adjusting the phase of the arm with respect to the source so that the arm engages the tail of each successive sheet. In the preferred form of the invention the conveyor belts are separated to form a gap occupied by a diverter, and a high speed nip is provided at the downstream end of the gap so that a sheet traverses the gap and is fed into the nip without changing its speed. For squaring up each sheet passing through the high-speed nip, a pair of squaring and press down rollers are provided at the downstream end of the second conveyor belt with means for adjusting the longitudinal position of the rollers so that they are engaged by the leading edge of the sheet just prior to engagement of the tail of the sheet by the knock-down arm thus insuring precise shingling and freedom from buckling of individual sheets. Infinetely variable cutoff is provided.

Abstract: ABSTRACT OF THE DISCLOSURE:    A dry system for forming and transferring images is provided.          The system comprises a photoactive component comprising a tacky photohardenable layer on a selected carrier sheet and a transfer component comprising a frangible color layer on a selected carrier sheet.  The two components are disposed with their photohardenable and color layers in air-free contact with one another and then subjected to irradiation with actinic radiation in accordance with a selected image pattern so as to cause selected portions of the photohardenable layer to harden and fuse to confronting portions of the color layer.  Then the two components are separated whereby the fused portions of the color layer are separated from its carrier sheet and transferred to the photoactive component.          Thereafter the color layer remaining on the transferable component is coated with a pressure-sensitive adhesive.  Finally, the transferable component is positioned with its adhesive coating engaging a receptor substrate and the rear side of its carrier sheet is rubbed hard or burnished with a suitable implement so as to cause the remaining image-defining portions of the color layer to separate from its carrier sheet and adhere to the receptor substrate.

Abstract: ABSTRACT            A typical door closer has a cylinder in which a piston reciprocates  to compress a spring.  An assister for such a closer has a cylindrical shell fastened to one end of and continuing the cylinder.  The shell has a barrier wall at one end adjacent the cylinder, a partition wall dividing the shell into a booster compartment and a main compartment, and a head wall at the other end.  Air under regulated pressure is supplied to the main compartment, wherein the air presses a main plunger tube, extending through the partition wall, against a booster plunger having a rod extending through the barrier wall and abutting the piston.  A port in the plunger tube receives air from the main compartment through the tube.  In some plunger tube positions the port is blocked by the partition wall and in other plunger tube positions opens into the first compart-ment.  A check valve when open allows air flow from the booster compartment to the main compartment.  Air under regu-lated pressure is supplied to the main plunger throughout the whole piston stroke and is supplied to the booster plung-er during only part of the piston stroke.  The applied air pressure is regulated to be slightly less than an amount necessary to compress the spring and move the door unaided.

Abstract: ABSTRACT OF THE DISCLOSURE   In a load system which involves a powdered chain hoist wherein raising or lowering of a load is effected by a rotating drive sprocket over which the chain is trained, the amplitude of motion due to resonant response of the load system as a consequence of coincidence between the natural frequency of the load system and the frequency of oscillatory excitation produced by the chain/sprocket drive is significantly reduced by providing an energy dissipation device in series with the load.  This device involves a spring mechanism which permits a limited motion at the resonant condition, in combination with a controlled damping factor.  The spring compliance of the device normally will lie in the range of about 1/2-3 time-the spring compliance of the active length of the chain at the resonant condition and the relation between the spring rate of the device and the effective damping factor is preferably such that the spring rate divided by the damping factor will be at least about .006 seconds.  The device so tuned is also effective in rapidly attenuating the amplitude of the transient motion induced  when the hoist is suddenly stopped or started.
