Abstract: A clamp for hydraulic hoses having a base member formed with one or more substantially half-circle cutouts and a clamp member pivotally connected to said base member and formed with corresponding substantially half-circle cutouts, such clamp member being pivotable from an open position to a closed or clamping position wherein the half-circle cutouts form full-circle passageways for individually retaining a hydraulic hose. A locking pin retains the clamp in its clamping position by insertion thereof in aligned through openings, there being a loop member or ring on the end of the locking pin to at least partially encircle the base and clamp members to retain the pin in its locked position.

Abstract: A holder for microphones and the like, attachable to a vertical wall and having a ledge member whereon the usual mounting button of a microphone is caused to rest by the force of gravity and a spring member fixed relative to said ledge member. Said spring member is formed with a slot, and the resiliency of said spring member urges said button to a position on said ledge member. Such resiliency can be overcome to enable said button to pass clear of the ledge member when desired for removal of the microphone.

Abstract: A fluid sampling apparatus having an elongated member which carries a pivotal platform at one end and a handle at the other end. An operating lever extends from the handle to the platform whereby a vessel attached to the platform can be pivoted by pulling the lever at the handle, thereby moving the vessel from inverted position to upright position to cause fluid at a predetermined depth or level within a body of fluid to enter the vessel.

Abstract: Ground-moving equipment comprising an arcuate main blade to be fixed to suitable motive power means such as a bulldozer or the like, and an elongated auxiliary blade hingedly connected to said main blade and operable for forming or cleaning a slope which extends upwardly or downwardly from the position of the bulldozer. More specifically, it comprises a pivotal connection between the auxiliary and main blades, and a hydraulic actuator also connected between such blades and operable to enable the relative positions of such blades to be changed from a remote location.

Abstract: The method of removing printing press rollers or cylinders, and a removal mechanism for use therein in extracting relatively heavy printing press rollers from very restricted and confined locations.The method comprises affixing to the frame of the press a pair of removal mechanisms, one at each end of the press. Each such mechanism comprises a mounting bracket including clamping means, a winch and an extension having an opening through which the winch line extends. The extension rests against the topmost rollers and the line is extended into the center of the press to be wrapped about the respective end of the roller to be removed. Simultaneous operation of such winches causes the roller to be lifted from its bearings or journal, thereafter to be lowered by means of the winches for manual removal.

Abstract: An electronic instrument case formed of breakable plastic and having a section of reduced thickness which is firmly secured to the remainder of the wall of such enclosure by a retainer. Such reduced thickness section can be broken away from the remainder of the wall of the enclosure but it is held in attached relation thereto to thereby provide a "breathing" opening for such enclosure.

Abstract: Friction welding apparatus for substantially automatically welding relatively small diameter workpieces.The apparatus comprises a pair of spaced segmented transfer wheels on a single shaft for retaining workpieces and rotating the same between loading, welding and ejection stations, and a plurality of high-speed motors which carry workpieces at the opposite ends of each rotor, such motors being moveable from a load station through a series of speed-increasing stations to a weld station between the several transfer wheels. Hydraulic means then forces the oppositely disposed transfer wheel segments in their weld stations toward the motor therebetween to simultaneously complete two friction welds. Thereafter, the parts are ejected when the wheel segments move to the ejection stations.

Abstract: A game board having a generally rectangular or square playing surface whereon hexagonal spaces are contiguously arranged along axes at right angles to each other and along an axis at 45.degree. to each of the other axes.Each such hexagonal space is elongated along a longitudinal axis which intersects a pair of opposite sides, said opposite sides being shorter than the other four sides of the hexagonal space. The spaces may be provided with different colors to distinguish them, as desired.
