Abstract: A light pipe component designed with optically transparent material capable of transmitting and/or guiding optical wavelengths. The outer surface of each light pipe being coated with a metallic surface finish, with the exception of the ends of the light pipe. The light pipe component being placed on a PCB to form solder joints between the metallic surface finish of the light pipes and the PTH. The solder joints may now be used for transmitting both optical signals and electrical signals per each physical connection of the light pipes.

Abstract: A socket including multiple contact areas socket contacts is provided. The multiple contact areas enable the placement of components, such as capacitors, resistors, diodes and the like between the socket and a substrate.

Abstract: A vertically adjustable seat post assembly for cycles includes a light-weight vertical seat post formed from a relatively soft high strength-to-weight material, such as a carbon fiber composition, and a relatively hard tubular protective tubular sleeve permanently secured concentrically about the lower end of the seat post. The outer diameter of the sleeve is slightly less than the inner diameter of the seat tube opening of the cycle frame, whereby the carbon fiber seat post is protected by the sleeve when the seat post is vertically adjusted and clamped within the seat tube opening.

Abstract: A vertically adjustable seat post assembly for cycles includes a light-weight vertical seat post formed from a relatively soft high strength-to-weight material, such as a carbon fiber composition, and a relatively hard tubular protective shim permanently secured concentrically about the lower end of the seat post. The outer diameter of the shim is slightly less than the inner diameter of the seat tube opening of the cycle frame, whereby the carbon fiber seat post is protected by the shim when the seat post is vertically adjusted and clamped within the seat tube opening.

Abstract: A floating swimming pool apparatus includes a rigid water retaining portion which includes rigid walls and a rigid floor. A peripheral deck portion is connected to top portions of the rigid walls, and a plurality of individually adjustable drum-like container are connected to the deck portion. Each of the drum-like containers includes a fill port through which a quantity of ballast material can be added to or removed from the drum-like container. The preferred ballast material is water. A layer of flotation foam material attached to exterior surfaces of the rigid walls and the rigid floor of the water retaining portion. Inner joists are connected to the deck portion proximal to the rigid walls of the water retaining portion. Outer joists are connected to the deck portion distal to the rigid walls of the water retaining portion. Each of the adjustable drum-like flotation assemblies is suspended from the deck portion by a suspension band connected to a respective inner joist and a respective outer joist.

Abstract: A method and apparatus to melt and withdraw petroleum residue from a storage site at a convenient location while causing the residue from more distant locations to melt and flow in a stream, to the removal location. A heated wand is utilized to heat the petroleum residue. The wand has one pivotally supported end and is moved in an arc about the pivotally supported end across the storage site with removal of heated petroleum residue occurring at substantially the center of the arc.

Abstract: A liquid seal valve arrangement is disclosed wherein two liquid seal tanks act in response to a differential pressure to divert a portion of waste gas being directed to a heavily loaded flare to an alternate lightly loaded flare.

Abstract: A manipulable device for projecting a horizontally-extending straight square edged light bar images upon a paper work sheet to facilitate the pasting of small adhesively-waxed printed pieces or strips to be placed upon a paper work sheet lying upon the base support of the device. The selected locations are determined and effected by relative fore and aft adjustment between a light bar projecting fixture and its base support with the work sheet thereon. Since procedure of pasting up of printed pieces upon a layout sheet can be done without the usual T-square and triangle, both hands are left free to carry out the pasting operation. Vertical guides are effected as vertical interferences of the projecting light rays and registerable upon the layout sheet along with the horizontally-extended light bar. Vertical and horizontal measuring rulers are provided upon the layout sheet base support to which reference can be made when locating the projected straight edge light bar upon the layout sheet.

Abstract: A loader and unloader mechanism is attached to a standard photoplotter equipment. The mechanism performs a sequence of operations for loading and unloading sheets of film onto and from respectively such equipment completely automatically.

Abstract: A tool facilitates the hand insertion of wire wrap square sectioned pins from a fanning metal strip into plated through holes of a wire-wrap printed circuit board. The tool includes a solid cylindrical tip which is mounted within a handle member which includes an automatic anvil. An end portion of the tip has a portion with stepped profile which contains a round hole. The hole is slightly larger than the square section of the pin and has a predetermined depth for positioning the pin in a vertical direction during an insertion operation. The sizes of the individual steps are selected to enable the pins to be ejected completely from the band portions of the strip into the holes of the board at a predetermined depth without damaging the strip or the areas surrounding the holes.

Abstract: A hand held tool for installing compression rings includes a pair of relatively reciprocable coaxial cylindrical independently spring biased elements housed within a cylindrical handle which includes mode control means automatically preconditioned for enabling the tool to perform either an installation or ejection operation. The mode control means includes a cylindrical radial cavity containing plural spring biased spherical ball detents and extends into corresponding portion of the outer reciprocable element. The positioning of a tapered central section of the inner reciprocable element coincides with the cavity so that one of the spherical ball detents normally sits within a hollow defined by the taper. When one spherical ball detent, in response to the mode control means being preconditioned by depressing a front end or shaft portion of the inner element, is positioned to lock the outer member to the handle, this allows the ring to be installed onto the cam shaped front end of the outer element.

Abstract: This disclosure pertains to an apparatus for use in heating containers of food, as in cans, bottles, plastic pouches and the like by emersion into water adapted to insure uniform heating thereof by substantially insulating the containers from thermal contact with all the parts of the heating apparatus except the water in contact with the container. The apparatus can also be used to heat water alone, brew coffee, tea or other beverages.
