Abstract: A two-way business-band transceiver for operation on an assigned FCC frequency includes a chassis housing a plurality of printed circuit boards which are surrounded by a three-part enclosure. This enclosure includes a main body portion having a top half and a bottom half and a control head portion which is separable from the main body portion. The transceiver circuitry which is arranged both within the main body portion as well as within the control head portion includes frequency synthesizing means which are selectable yet nonaccessible from the front of the control head portion. Frequency selection is accomplished by gaining access to a programming circuit portion which is located within the control head portion. This programming circuit portion includes a plurality of 10-position, rotary BCD switches which are arranged for channel 1 and channel 2 operation.

Abstract: A machine tool collet having a generally cylindrical body with a longitudinal axis. The collet is divided into a plurality of segments each having front and rear surfaces and endfaces with recesses. The recesses hold biasing springs which force each segment away from the adjacent segment.

Abstract: A throw toy has spoke-like graspable members of differing lengths which extend from a central hub at approximately the same angle with respect to each other and have bulbous ends such that the toy is balanced for throwing and is readily catchable. The hub and the spoke-like members may represent the head of an animal-like figure.

Abstract: A forming press is disclosed having a press frame, a slidable press carriage, and at least one tool couple comprising a plunger and a matrix. A pressure member is movable in the direction of motion of the press carriage for bracing the plunger against the press carriage. A screw controlled adjustment means including a motor is mounted on the press frame for driving the screw of the adjustment means and thereby positioning the pressure member. A drive gear is mounted on the screw, and coupling means is provided for connecting the motor and the drive gear at a predetermined position of the press carriage.

Abstract: A modification is provided in an assembly for use in an offshore well test string during oil or gas tests on exploration wells. The well has a well bore and a test string with a subsea test tree located in the vicinity of the subsea blowout preventor at the sea floor. The modified assembly includes at least one line having one end in communication with a supply of methanol and the other end in communication with the test string below the sea floor.

Abstract: A rigid laryngoscope having a forwardly extending blade and an instrument supporting channel. The laryngoscope includes a viewing assembly and light source each connected to fiber optic bundles.

Abstract: A fabric for reinforcing elastomeric or other plastic materials comprising a steel cord warp and a steel weft wherein the warp cords are substantially sinusoidal and have an elongation of about 1-2% at 10% of the breaking load of the fabric and the weft elements are substantially straight.

Abstract: A paper roll holder having a roll supporting member for engaging the core of a paper roll, the supporting member having a planar main portion adapted to be disposed generally parallel to and adjacent a diameter of the paper roll core, lateral flanges extending from the main portion at each side of the main portion over most of the length of the main portion, each flange being disposed at an angle equal to or slightly less than 90.degree. with respect to the main portion, and an arcuate area encompassing the juncture of the main portion and each flange defining a shoulder for engaging the paper roll core, the main portion being of such a width that each arcuate area continuously engages the paper roll core for applying frictional pressure to the paper roll core whereby paper delivery is limited in that the paper roll core is only capable of limited rotation on the supporting member.

Abstract: An air conditioning system ceiling air outlet comprising a warm air duct for vertically downward direction of warm air, a cold air duct surrounding the warm air duct for outwardly directing cold air, the ducts terminating at their inlet ends in a common connecting stub, covering plates for the intake ends of each of the ducts and mounted in the connecting stub, the covering plates being mounted on a common axis of rotation and at an angle to each other so that when one of said ducts is closed by one of said plates, the other of said ducts is open.

Abstract: A motor vehicle having excavating machinery mounted thereon and having at least two axles, at least one of which is driven, and further including an operator cab, the vehicle having counterweights on each lateral side of the cab, guides for the counterweights extending lengthwise of the vehicle on each lateral side of the cab, the counterweights being movable along the guides from a first position above one of the axles to a second position above the other of the axles, and apparatus for selectively securing the counterweights in each of the two positions.

Abstract: A method for the preparation of hexagonal nuts by cold forming wherein a blank is shaped and formed to a hexagonal configuration wherein the distances across the flats of the hexagon are greater than in the finished nut, and thereafter the rough nut is forced into a shaping die and over a punch concentric therewith, whereby the punch forms the central opening in the nut and the shaping die reduces the distances across the flats of the hexagon to that of the final nut size.

Abstract: A leaf stripper for tobacco stalks and the like including cooperating leaf stripping means, means for moving the stripping means to form a nip, and stalk supporting an infeeding means including a rotating support table mounted adjacent the stripping means in the area of the nip with the infeed axes parallel to the axes of the nip, and the method for stripping the leaves from the stalk.

Abstract: A process and apparatus for heat laminating a light gauge plastic film to a heavier substrate material. The film and substrate are fed between rotating laminating rolls, one of which is heated, the rolls being urged against each other under pressure. Prior to lamination, the substrate is positioned on a supporting surface of hard, flexible material in the form of an endless belt or sheet which passes between the rolls, or a smooth flexible sleeve secured to one of the laminating rolls. During lamination, the substrate adheres to the flexible supporting surface, and the substrate is maintained in engagement therewith for a predetermined time after lamination to permit the same to cool and stabilize in order to prevent the formation of ripples therein. The film may have a decorative coating applied to one face thereof, which is transferred to the substrate at the time of lamination and the film may be optionally peeled off the substrate leaving only the decorative coating applied to the substrate.

Abstract: A tool for opening containers having either tearaway tab and closure panel structures or inwardly pivoting closure panel structures is disclosed, the tool having an elongated body with a hook member at one end, a first projecting member with a generally convex projecting end surface lying on a longitudinal line with the hook member, and a second projecting member having a second generally convex projecting end surface on a longitudinal line with the first convex surface, the two projecting members having a gap therebetween.

Abstract: Means for collating a flow of rod-like elements moving in a lengthwise direction comprising a rotatable drum arranged to receive the elements on its outer surface and move them transversely to their lengthwise direction, said drum having a porous wall and being rotatable through a reception zone where a fluid bed is created on its outer surface to assist reception of the elements thereon, a holding zone where a vacuum is created to hold the elements on the drum, and a discharge zone where fluid pressure is provided to assist discharge of the elements.
