Abstract: A survey monument having cylindrical rod sections which are assembled in end-to-end relation with threaded connectors as the monument is driven into the ground. The monument has a penetrating point which has generally longitudinal barbs spaced about the periphery of the point. Each of the barbs has a turning surface biased about 5.degree. for rotating the point in a direction to tighten the threaded connections of the monument in response to downward driving of the point into the ground. Each of the barbs has an upwardly facing retention shoulder to prevent removal. A marker cap is tap fit over the top of the uppermost rod section. The parts are metallurgically matched for ultimate natural fusion and to prevent galvanic action or electrolysis after the monument is emplaced in the ground.

Abstract: A tool for removing embedded screws and the like, having a pair of pivotally connected handles with screw removing heads at the ends thereof. The screw removing heads each have matching opposed clinching edges, including a pair of laterally spaced parallel clinching edges and a clinching edge at the bottom of each head which is perpendicular to the parallel edges and disposed between them. The parallel edges dig into the periphery of the screw head to allow torque to be applied to the screw as the handles are turned by a user, while the perpendicular clinching edges engage the underside of the head of an embedded screw to oppose slipping movement of the tool off the screw head and apply upward force thereto.

Abstract: A liquid dispensing nozzle is provided with a liquid discharge tube and a vapor recovery tube, both of which are adapted to be inserted into the fill pipe of a tank such as a motor vehicle gasoline tank. While gasoline or other volatile liquid is discharged through the discharge tube, a substantially equal volume of vapor is withdrawn through the vapor recovery tube to a pneumatic pump portion of a hydraulic motor-pneumatic pump device. Gasoline flowing through a hydraulic motor therein drives the pneumatic pump, which is operably connected to the hydraulic motor to be driven in synchrony therewith. The volume of vapor withdrawn from the fuel tank is adjusted to be approximately equal to the volume of liquid discharged, such that the pressure inside the tank is substantially atmospheric, and the end of the fill pipe of the tank may be sealed to prevent vapor from escaping or air from being drawn into the tank.

Abstract: A method of and circuitry for correcting gamma ray camera data signals for signal processing circuitry is disclosed. Pulses are artificially generated which replicate the data signals produced at the output of photomultiplier tubes of the gamma ray scintillation camera and are inserted in the gamma ray camera internal processing circuitry in such a manner as to remain distinguishable from the data signals generated by the photomultiplier tubes. By monitoring the number of artificial pulses produced artificially and the number of such pulses actually counted by the data processing circuitry of the gamma scintillation camera, a factor indicative of the losses of scintillation count in the processing circuitry may be determined.

Abstract: A coin-controlled, manually operable machine for vending several dozen golf balls at a time. The vending machine has a ball hopper and a ramp below the hopper defining a ball dispensing opening between them. A gate rotatably mounted at the opening, extends partially there across in its closed position to cause the balls to bridge the opening. When the double-stroke actuating lever is pulled forward and returned, the gate is swung or kicked into the mass of balls twice to break up the bridging of balls to release a sufficient excess of balls down the ramp to assure filling of a rotatable ball receiver-dumper cylinder extending across the bottom of the ramp. The actuating lever is maintained inoperative by a coin-releasable locking mechanism. The receiver-dumper cylinder has a keeper slot receiving a limiting lug.

Abstract: A device for calculating decompression plans prior to an underwater dive, and for monitoring the depth of a diver during an actual dive and continuously computing a safe decompression plan. The many tissues of a diver which absorb and eliminate inert gas are approximated by a single tissue having different time constants of uptake and elimination of inert gas. These time constants and discrete values of supersaturation ratio may be chosen to allow calculating of diving plans which approximate diving schedules determined empirically.

Abstract: Process for transferring overlayed multiple ink patterns from the surface of a release blanket to a receiving surface on a container or other formed article being printed. A substantially transparent film is first formed on the release blanket, with each ink pattern being printed sequentially over this release film. Proper printing on the release film without picking the release film or previously applied ink films is obtained when certain adhesive and cohesive relationships are maintained between the ink films and the release film. An adhesive film may be formed on the article to be printed, or it may be formed over the ink films and the release film on the release blanket. The receiving surface on the article to be printed is brought into contact with the films on the release blanket, with a resulting total transfer of the films on the blanket to the surface of the article.

Abstract: A method and device for multiplexing time varying amplitude physiological data signals with the signals provided by the photomultiplier tubes of a gamma ray scintillation camera. The time varying amplitude signals from physiological sensors are converted to a series of uniformly shaped pulses having a pulse frequency which is directly proportional to the amplitude of the physiological signal. The pulses are shaped to correspond to the shape and size of significant pulses provided at the output circuitry of the photomultiplier tubes of the camera. The shaped pulses are combined with the pulses provided by a photomultiplier tube, and are processed by the internal circuitry of the gamma ray camera in the same manner as gamma ray scintillation data. A computer can be utilized to process the data thus provided, and to display the gamma ray scintillation data in time synchrony with the physiological signal source data.
