Abstract: A portable ground water sampling apparatus has a submersible pump or other water sampling apparatus attached through a hose to a hydraulically driven spool mounted on a boom attached to the bed of a truck or trailer. The hydraulically operated boom enables the operator to place the pump over the well and lower the pump into the well from the spool. A second spool also mounted on the boom operates a cable attached to a discrete liquid sampler or appliance of operator's choice for lowering into the well to take water samples or collect data. A decontamination apparatus is also attached to the boom and washes the hose and cable to remove contaminants therefrom. The contaminated wash fluid is removed to a holding tank for later disposal at a safe site. Hydraulically driven level-wind mechanisms are attached to each spool. One or more computers are used on site to track the pumping and purging, as well as monitor sensors measuring fluid characteristics, such as, temperature of the water, conductivity and flow.

Abstract: A boat anchoring apparatus according to the invention has an elongate rod with a planar end piece attached at one end thereof for driving vertically into the sand or soil on a beach or waterfront. The rod is driven into the beach using a driving device having a weighted closed end with hollow tube for placement over the rod and having an elongate aperture along the length of the tube with a securing pin for attachment to the rod for pulling the rod out of the soil. Attached to the driving device is a pawl actuating mechanism for securing a line from the boat to said pawl when the rod is vertically in the soil and one end of the driving device is slidingly secured over the vertical rod locking at 90 degrees detaining forward tilt of buried rod and maximizing horizontal direction of vector forces.

Abstract: A portable folding feeder for livestock having a vertically disposed back panel adapted to be secured to a vertical support wall when in use, and has a pair of side mounted doors swingably attached to either side of the back panel. A bottom flexible panel of cloth, leather or the like is mounted on the bottom of the feeder and can be folded upwardly into the feeder when not in use. A grate is provided for holding feed for the animals and is rotatably attached at the bottom of the back panel and drops forward to secure itself to both side doors when in use.

Abstract: An ultrasonic measuring device that is especially suited to nondestructive testing of materials is fitted with an ultrasound test head 72, a transmitter (74) and a receiver (76) that is characterized by a broadband logarithmic amplifier (78). This amplifier consists of several amplifier stages that are identical in construction and connected in series. Each amplification stage is characterized by the fact that it contains two transistorized individual amplifiers, namely a first and a second differential amplifier that are connected to one another and whose transistors (20, 22; 24, 26) are each interconnected at their base and at their collector. Each of these transmitters is connected at the emitters via inverse feedback resistors (34, 36; 40, 42) to a constant-current source (46, 50).

Abstract: A roof support column used as a support between the roof and floor of a mine comprises a stacked series of hollow roof support cribs containing a mixture of light-weight aggregate such as volcanic lava, tuft, or pumice, and a chemical foam contained in a double-walled high density paper tubing. The combination of these materials results in a roof support crib which has the yielding characteristics of wood. Such cribs called variable yielding cribs are stacked and locked on top of one another to form a vertical cylindrical cribbing support column.

Abstract: In a process for ultrasonic testing of elongated, prism-shaped sections (22) with at least one planar outer surface (54) extending along the longitudinal axis (26) of the section, with the objective of detecting material defects or verifying geometric data, the section (22) to be tested is exposed to ultrasonic beams from several ultrasonic probes (28 to 34) installed in a probe carrier (44). The section (22) is moved along its longitudinal axis (26) in relation to the probe carrier (44). The latter is installed in the rotor (20) of a rotary testing machine which rotates around the longitudinal axis (26) of the section (22).

The hydraulically operated boom enables the operator to place the pump over the well and lower the pump into the well from the spool. A second spool also mounted on the boom operates a cable attached to a discrete liquid sampler or appliance of operator's choice for lowering into the well to take water samples or collect data. A decontamination apparatus is also attached to the boom and washes the hose and cable to remove contaminants therefrom. The contaminated wash fluid is removed to a holding tank for later disposal at a safe site. Hydraulically driven level-wind mechanisms are attached to each spool. A washer is provided for high or low pressure washing of bailers or other devices used to sample well water.

Abstract: A device for detecting the presence of a vehicle by means of an ultrasonic device has an ultrasonic sensor (22) associated with an electronic transmitting and receiving circuit (28, 30). The sensor (22) emits periodic pulses whose reflections are received and evaluated by the circuit (28, 30). A positive presence signal is emitted if reflections are present. To ensure that a positive presence signal is always obtained irrespective of the shape of the vehicle and of the part of vehicle which has just been identified, the ultrasonic device has a central sensor (22) and two external sensors (26, 28) situated equidistant from the latter and at the maximum possible distance apart. The external sensors (25, 26) are connected identically and operated on a par with each other. Either the central sensor (22) is connected as the receiving sensor and the external sensors (24, 26) as the emitting or vice versa.

Abstract: A shoe insole in the form of a separate insole or an integrated insole attached to the shoe is manufactured from a material with a consistency ranging from flexible to rigid. The upper surface which is generally smooth and which is formed to fit the sole of the foot has at least one local depression opening into the upper surface of the insole with a gently rounded rim along the entire length of its edge and having within this rim a base lying a few millimeters deeper than the intact upper surface of the insole and being in area significantly smaller than the entire surface area of the upper surface of the insole. Further on a projecting knob is arranged in the central area of this base the free tip of which lies, essentially, at the same level as the course of the intact upper surface of the insole.

Abstract: A topical preparation for aiding in the care of minor skin irritations, such as chapping, reddening, tenderness, and the like, has as its constituents a mixture of glycerin, stearic acid, cocoa butter and boric acid blended together in a creamy base.

Abstract: A light-weight roller for rolling covering to uniformly distribute adhesive between the floor covering and floor, and to remove bubbles from therebetween. The roller utilizes removable, adjustable diameter rollers and has an adjustable handle to provide a variable rolling force on the floor covering depending upon the weight applied by the installer. The device is capable of applying floor coverings in a toe-kick space and in removing bubbles from beneath the floor covering.
