Abstract: A secondary snow removal structure is attached to the back of a primary snow removal device. The secondary structure includes a plurality of individual fingers positioned and arranged to extend below the level of the lower edge of the primary snow removal device for engagement with the surface being cleaned. A separate spring biasing means is provided for each finger for independently extending each finger to follow uneven portions of the surface being cleaned and thereby loosen and remove residual snow and ice compacted and left by the primary device.

Abstract: An apparatus for automatically applying a pressure-sensitive tab to the edge of a mailer which includes a feed spool of pressure-sensitive tape. The pressure-sensitive tape is fed through a tape slot of a tape guide block from where it is wound upon a driven windup spool. A pneumatically driven (or, if desired, solenoid driven) punch and die arrangement is positioned so that upon actuation, the die cuts a circular segment of the tape and wiper arms apply the circular cut tape segment to the edges of a mailer. This can be done while the edges of the mailer are stationary or moving parallel to the direction of the tape.

Abstract: Apparatus for accurately dispensing and positioning a credit card onto a predetermined area of a surface, includes a support tray which supports a stack of cards; a pusher assembly including a pusher plate which pushes out a leading edge of a lowermost one of the cards in the stack; gripper jaws which grip the lowermost edge of the pushed out card; and a control assembly which controls the gripper jaws to grip the lowermost edge of the pushed out card, to move over the predetermined area of the surface and to then release the gripped card so that the latter drops onto the predetermined area of the surface.

Abstract: A signalling tag of the type used in house arrest systems has a tamper detection device for detecting removal of the tag from the monitored person. The signal is set to a tamper condition upon removal. The tamper detector can only be reset to the normal state by a reset signal which incorporates a characteristic of the signal sent by the tag. This provides enhanced protection against attempts by the monitored person to defeat the system through unauthorized resetting.

Abstract: A storage device for panty hose that can be placed in a dresser drawer and will hold a plurality of panty hose in a compact, orderly and attractive fashion. The storage device includes perpendicular partition members which form compartments and which members can be collapsed when not being used to store panty hose.

Abstract: Apparatus for cutting a cruciform shaped radioactive control rod into three separate cut sections, the cruciform shaped radioactive control rod being of the type having four substantially equidistantly spaced sheaths extending from and along a large portion of the length thereof, each sheath containing at least one radioactive rod, and a velocity limiter at one end thereof, the apparatus including a first cutting device for cutting the velocity limiter away from the remainder of the control rod to form a first one of the cut sections; and a second cutting device for simultaneously cutting the remainder of the control rod along the lengthwise direction thereof and substantially transverse to the first cutting device, to form two chevron shaped sections as the remaining two of the cut sections.

Abstract: A method of implanting an intraocular lens in a human eye, includes the steps of (a) making a first incision in the eye not greater than 2.5 mm to allow a cataract lens to be extracted therefrom and a rolled intraocular lens to be inserted therethrough, the intraocular lens having a positioning hole for permitting positioning of the lens in the eye; (b) making a second incision in the eye of approximately 1 mm and spaced from the first incision to allow an intraocular lens positioning tool to be inserted therethrough; (c) pushing a rolled intraocular lens having a wrapping about at least a portion of the rolled intraocular lens into the eye through the first incision; (d) cutting the wrapping from the rolled intraocular lens in the eye so that the rolled intraocular lens unrolls in the eye; (e) removing the cut wrapping from the eye through the first incision while the lens position is maintained; and (f) final positioning of the unrolled intraocular lens in the eye.

Abstract: A white blackout fiber comprising a core, a sheath, said sheath surrounding said core, said core including a light blocking substance therein that substantially prevents the transmission of light therethrough, the light blocking substance being in an amount equal to 0.005-0.01 weight % of the core, a whitening agent in the core in an amount equal to 3-10% of the weight of the core, and a whitening agent in the sheath in an amount equal to approximately 0.0-4.0 weight % of the sheath.

Abstract: An electronic system for automatically identifying objects employing microminiature electronic circuitry supported by each object and containing three operable subsystems, (a) a means for converting shortwave energy from a local energy field to electrical energy, (b) a means for generating coded electrical signals and (c) a means for shortwave transmitting such signals as codes to a local receiver. The system also includes a shortwave receiving means and an electronic computer operable to process and analyze the coded signals received by the receiver from the electronic circuitry energized when in the energy field. The computer generates control signals which are recorded and are utilized in tracking the objects.

Abstract: A solder composition for use in high-speed hand-soldering of art work or other artifacts consisting essentially of from about 51% to about 56% by weight tin, from about a trace to about 1.0% by weight antimony, and the balance being substantially lead.

Abstract: Apparatus for banding a stack of envelopes includes an elevator mechanism which moves the stack in a path between a first lowermost position to a second uppermost position; first and second tensioning units for applying a tensioning force to a first banding strap positioned across the path at a first location between the first and second positions and extending in a first longitudinal direction; first and second sealing and separating units for wrapping, sealing and separating opposite ends of the first elastic banding strap about the stack of envelopes when the elevator mechanism has moved the stack of envelopes past the first location; third and fourth tensioning units for applying a tensioning force to a second elastic banding strap positioned across the path at a second location between the first and second positions and extending in a second widthwise direction substantially transverse to said first longitudinal direction; third and fourth sealing and separating units for wrapping, sealing and separating

Abstract: A muscle exercise and/or rehabilitation apparatus includes a fixture against which a force can be applied; a sensor which senses the force applied to the fixture and produces a load signal corresponding thereto; a speed detector which produces a velocity signal corresponding to the speed of the fixture; a servo motor which produces a rotational output of an output shaft thereof; a closed loop servo circuit which controls the motor in response to the load signal and the velocity signal to control rotation of the output shaft of the servo motor; and a conversion device connected between the fixture and the output shaft of the servo motor for translating the rotational output of the output shaft to linear motion of the fixture, the conversion device including a frame formed by a base, two spaced vertical support bars extending upwardly from the base, and an upper cap securing upper ends of the vertical support bars together, two vertical guide rods supported by the frame, a slide movable along the guide rods in

Abstract: Gaming layout arrangements having jackpot areas and methods therefor are provided in accordance with the present invention. One or more geometric forms are established on a traditional gaming layout where markers such as dice are employed in normally playing the game. When a marker employed in playing the game happens to land within a geometric form associated with a jackpot, a jackpot condition is defined. The size, shape, number and value of each geometric form may be varied to define the value and probability of achieving a jackpot condition.
