Abstract: A combined tape measure and marking device that includes a housing in which a spool is rotatably supported and on which an elongate tape is wound, which tape has measuring graduations extending the length thereof. A spring-loaded arm is pivotally supported from one side of the housing. The arm, on the forward end thereof, supports an alignment arrow and marking device, which alignment arrow may be transversely aligned with a desired graduation on the tape, when the free end of the tape is held at a fixed position on the material or article to be measured.The pivotally supported arm adjacent the arrow supports a manually operable marking device, with the device being actuated manually after the alignment arrow is aligned with the desired graduation, and the actuation resulting in a mark being placed on the article or material being measured. When the arm is released, the arm automatically assumes a second position where the marking device is out of contact with the article that has been measured.

Abstract: An immersible instrumentation array for sampling the oil percentage, temperature and flow rate of well fluid comprising a plurality of circuit wafers, each including feedthrough connections, such wafers being arranged in an axial column having various instruments dispersed therethrough. This arrangement allows immersion of the instrumentation array into a well bore with minimal restriction to flow. To permit insertion of the array to various well depths, a single lead shielded coaxial cable attaches to the top of the array providing both the power to the various instruments and returning the measurement signals through the feedthrough connections in the wafers. To accommodate both the power signal and the measurement signals within a single lead, the signals are separated by frequency, the instrument readouts being selected in sequence by way of a pulse commutation technique.

The assembly may be actuated to create a negative pressure to draw a liquid that may contain entrained particles of solid material into the interior of the assembly. After the assembly has introduced liquid therein in a desired volume, it may subject the liquid to positive pressure to separate particles of solid material such as protein, bacteria and viruses from the liquid.Liquid free of solid particles, may be discharged from the assembly through a hypodermic needle that is removably secured to the assembly. A magnetically attractable body may rest on the filter within the interior of the assembly.

Abstract: The weapon release assembly includes an articulate structure capable of being mounted at a desired position on an aircraft to triaxially support and restrain movement of a launchable weapon relative to the aircraft, until it is desired to launch the weapon. When the assembly is actuated to launch the weapon, the weapon is moved outwardly along a path normal to the longitudinal axis of the aircraft to a desired position where it is released from the system at a desired velocity. Operation of the assembly may be by either hot or cold gas. All forces arising from use of the assembly in supporting the weapon and launching the latter are transmitted directly to the aircraft on which the assembly is mounted. The assembly by buffering the actuating gas, is susceptible to being used to launch weapons of various weights at the same terminal velocity without adjustments or corrections being made to the assembly. Preloading of weapon on the assembly may be accomplished either manually or automatically.

Abstract: A golf club head weight adjustor assembly that includes an elongate tube of a resilient material that has first and second ends, and the tube capable of being removably disposed in an elongate cavity in the club head that is substantially parallel to the ball striking surface of the head. The tube has first radial openings adjacent the ends thereof. A number of longitudinally spaced, radial, second openings are defined in the tube that are transversely aligned with third radial openings. Rigid weight balls, each of a fourth diameter greater than that of the second openings, can be forced radially through the second opening into the bore of the tube to be frictionally gripped by the latter and occupy a fixed longitudinal position therein. A closure removably engages the head to close the cavity to maintain the weight adjuster within the confines of the latter. A tool is included as a part of the assembly, which tool has a pin and hook formed as an integral part thereof.

Abstract: An alarm system for indicating the unauthorized withdrawal of an appliance lead from a wall receptacle includes a spring biased arm extending partly through the ground connector opening of the receptacle against a microswitch. When the plug is in the receptacle the arm is displaced by the ground terminal of the plug away from the microswitch, opening the switch. The microswitch is connected in series with a master switch which, in turn, connects to an audio alarm. Upon withdrawal of the plug from the receptacle, the spring biasing forces of the arm direct the arm both across the ground terminal openings and against the micro-switch, closing the circuit to the alarm. Should the plug be removed, a slot is provided in the wall plate through which a key is insertable to withdraw the arm from the ground terminal opening, thus permitting reinsertion of the plug.

Abstract: A multiple pattern display device comprising a plurality of strips interlaced in a weave to expose selected sections thereof. The strips are attached to rollers at the ends thereof, and as the rollers are driven in rotation the exposed sections of the strips within the weave are varied. In this manner various messages can be sequentially displayed. The weaved arrangement of the strips is maintained in a coherent relationship by gearing the rollers such that as the rollers are turned various messages are formed by the exposed group of strip segments. During the transition between messages a kaleidoscopic effect is produced which typically is interesting to viewers.

Abstract: A down hole forward and back scuttling tool capable of being removably connected to a power driven drill string and to an expandable reamer to transmit torque from the drill string to the reamer as the latter is transversely expanded and rotated to form an elongate cavity in the lower portion of the bore hole. The reamer is of a conventional type that permits fluid under pressure to discharge therefrom. The tool during the reaming operation permits fluid under pressure to flow downwardly in a first path through the drill string, tool and reamer to exit from the latter into the cavity and then upwardly through an annulus shaped space defined between the side wall of the bore hole and drill string to the ground surface. Cuttings from the reaming operation drop downwardly due to gravity to the bottom of the cavity. It is desirable that such cuttings be removed from the cavity prior to the latter being packed with gravel. The tool permits these cuttings to be retrieved.
