Abstract: A carpet or fabric screen printer has a plurality of size-adjustable screen printing rolls mounted on re-positionable heads on a long frame for the purpose of repeating a pattern in different colors. Each printing head comprises a screen printing roll on which is mounted the screen and inside of which is mounted a roller of magnetically attracted material or having a magnet unit having both North and South poles along the length thereof. The magnetic roller rolls when the head is in operation but remains in one position with respect to the screen printing roll. A continuous conveyor belt delivers the fabric sheet beneath the screen and the roller inside the screen roll. A second magnetic roller on the head beneath the conveyor belt and on the other side of the conveyor belt from the screen and the second roller also has North and South poles which are attracted by corresponding opposite poles on the first roller.

Abstract: Conventional multi-needle tufting machines may be modified and provided with the special looper element of the present invention so that without backdrawing or robbing from a previous loop a row of stitching is formed to provide a pattern of any number of high cut loops and low cut loops. The looper element is reciprocated by the conventional mechanism and the loops are cut by long and short knives reciprocated by the conventional knifebar on the machine. The looper element may be made from flat plate in one plane to provide a support portion and a closed end, like a nose with an internal space, which enters the loop. A bottom member like a finger on the nose and a top member defines the internal space which is substantially closed by means of the bottom member except for an offset entrance having a small angular configuration. The small angular entrance leads to the space in the looper element in which a short loop supplied by a pattern control means is confined until cut.

Abstract: Combustible materials, including plastic sheets, plates, and blocks, also leather and all varieties of wood, may be cut along predetermined lines by engaging same with a heated reciprocating wire at temperatures which vaporizes the material rather than melting same. The machine providesa reciprocating wire which is heated by electrical resistance. A system of air quenching of the wire above and below the cutting zone is employed in order to attain incandescent temperatures at the point of cutting.

Abstract: Drive-in banks, some large service stations and similar operations use cashiers windows located on small islands at a remote place from the central building.

The lifting frame is attached to the refuse container by means of a flexible chain or cable which is secured to the refuse container and holds same in place during transport.

Abstract: A hand-crank operated golf ball washer comprising a cylindrical container in which there is an elongated drive shaft supporting a first scrub element covered in a plastic outdoor carpet material, a second and shorter cleaning element which is covered with the outdoor carpet material, and a third, drying element covered with a towel-like drying material. The ball is directed through helical grooves formed in the outer periphery of the inside of the casing and spaced from the different elements just the correct amount to force the golf ball into contact therewith. Plastic sponge elements are placed within some of the helical grooves and absorbent towel elements are placed in others. The elements are separated by baffles with aligned openings therein to transfer the golf ball.

Abstract: Each of the opposite ends of a basically conventional mailbox is provided with a hinged closure which operates a signal device which is pivoted on the side of the mailbox so as to be elevated by the opening of the entry or deposit end of the box and to be lowered upon the opening of the exit or removal end of the mailbox. The entry closure operates a spring mounted rod to lift the signal device and the exit closure operates a small chain to drop the signal device back to its normal lowered position.

Abstract: A cylindrical metal barrel is joined to the heads or closures on opposite ends by the bending together of the annular material of the head and respective barrel end to form the usual double seam made by seamer rolls brought to engagement by means of cams. The metal barrels are supported between movable heads on which are mounted respective barrel chucks driven by respective and individual chuck spindles driven from a respective motor and clutch drive on each head. A power take-off operates a common drive shaft between the heads which has the actuating cams thereon that vertically move the seaming rolls. Thus, there is independent operation at each end of the barrel on each head for making each respective double seam.

Abstract: A woven fabric shade screen comprising substantially even spaced elongated strands in one direction, such as the fill direction, and groups of more closely spaced strands woven so that the two outside strands alternate respectively being over and under successive fill strands while the inside four strands in each group are arranged so that the third and fifth strands are under a fill wire while the second and fourth strands are over, thus providing alternate strands which alternate each fill strand.

Abstract: A system including apparatus for automatically and continuously, or intermittently, feeding disposal material such as highly combustible waste plastic in containers such as 55 gallon steel drums or in packages such as 30 gallon sizes into a rotary kiln or any other appropriate receiver. Highly combustible or explosive materials must be placed carefully into a rotary kiln or other type of combustible disposal equipment because of the likelihood of explosion or blow back when the material reaches the heat. Such material contained in packages of 55 gallon steel drums or in bales or disposable cartons is delivered by conveyor to a grid for raising same and in clamping means which holds the reclaimable drum and tilts same through an openable closure into the furnace or incinerator, dumps the container and returns it to reclaimable position to be moved on out another conveyor system.
