Abstract: An inflatable wearable flotation device having flotation material in front and back panels and an inflatable bladder having sections located at said front panels and a collar section positioned over said back panel comprising a bladder section, and fastener means for maintaining said bladder sections flat when fastened and being unfastened by expansion of the bladder sections to permit inflation of the bladder.

Abstract: The herein disclosed test instrument includes an arrangement for measuring the standing wave ratio of a transmitter, antenna combination which comprises a printed circuit board having a first conductive path thereon adapted for connection in series with the energy flowing between a transmitter and its associated antenna, a second conductive path contiguously disposed on the printed circuit board such that energy is electro-magnetically coupled from the first to the second conductive paths; circuit means for sequentially measuring the energy flowing in opposite directions along the second conductive path; and meter means for displaying the ratio of the measured energy. The test instrument further includes a circuit for measuring the transmitter's output power wherein the "loading" of the metering circuit on the transmitter is substantially reduced.

Abstract: A recording compression testing meter having a measuring cylinder connected to the spark-plug hole of an engine cylinder by means of a tube and having an indicator arm movable by the piston of the measuring cylinder over a portion of recording paper fed from a roll of paper carried in a removable cartridge, the paper being fed from the roll by a drive mechanism carried by the cartridge so that tests of a large number of cylinders can be recorded on the continuous sheet of recording paper fed from the paper roll before it is necessary to reload the meter and the test of the cylinders of each engine can be torn off and stored separately.

Abstract: A battery operated screwdriver wherein a battery and a motor assembly are mounted within an elongated housing, the motor operating a drive shaft extending from the housing, the drive shaft being off-set from the longitudinal center axis of the housing producing a weighted one longitudinal side of the housing, an operating switch assembly mounted within the housing, the operating switch assembly located along a longitudinal side of the housing which is opposite said one side.

Abstract: An apparatus and method for harvesting earthworms from a bedding comprising a drum rotatably mounted upon a housing, the housing including a base which is adapted to be placed upon a planar supporting surface, the drum being formed of a plurality of parallel elongated rods arranged in a circular manner with spaces between the rods, the longitudinal center axis of the drum being located in an inclined manner with respect to the base of the housing, and material inlet means connected to the housing to supply material to the interior of the drum, outlet means connected to the housing located adjacent the other end of the drum for discharging material from the interior chamber of the drum, and means for effecting rotation of the drum with respect to the housing.

Abstract: A mechanism providing both a brake and tie-down mechanism for a cart which utilizes a central support below the bottom of the cart for supporting both the vertically moving brake shoes and the rotating locks of the tie-down mechanism, and foot pedals at opposite ends of the cart for engaging and disengaging the brake shoes with the supporting surface and for rotating the locks to release the cart from the tie-down mechanism, the tie-down mechanism being arranged to receive a tie-down mushroom from either end of the cart.

Abstract: A duraguard for a surgical cutting tool consisting of a guard mounting member rotatably mounted within the nose section of the tool housing at two spaced locations and supporting a guard arm extending outwardly along the cutting tool and terminating a protective foot extending over the end of the cutting tool to separate the dura from the skull, the arm and foot being rotatable relative to and about the cutting tool in order to follow curved slots formed by the tool.

Abstract: A tone arm which uses a suspension instead of a conventional arm and pivot. It is designed to reduce mass by reducing the physical size of the components of the device. It also provides a suspension that is more compliant than that of the cartridge stylus suspension. Tracking is provided in a straight line eliminating skating force and track error. A linear bearing provides very low friction translation of the carriage on the track.

Abstract: One embodiment of the herein disclosed switching arrangement comprises a printed circuit board having two parallel slots formed therein with a plurality of contact points disposed between the slots; and a housing mounted so as to allow its movement along the slots and including at least one electrically conductive member mounted within a cavity in the housing such that for different positions of the housing along the slots in the printed circuit board different ones of said contact points are shorted together.

Abstract: A moisture meter construction in which a conventional meter assembly is mounted within a housing, an access opening into said housing, a tubular member integrally secured to said housing having an opening therethrough with the opening of the tubular member being aligned with the access opening, an annular chamber surrounding the tubular member, a metallic probe assembly tightly fitted within said annular chamber, a tapered plug member surrounding a portion of the metallic probe assembly being snugly located within said annular chamber, the free end of the probe assembly having an electrical insulator placed within the metallic probe member and a dissimilar metal located interiorly of the insulator with the entire probe assembly being tightly sealed.

Abstract: An electrical meter apparatus wherein the elements of construction of the meter are so constructed as to not warrant any significant amount of precision in manufacture. A selector knob is connected to a switch rotor with a switch rotor being mounted upon a panel bushing which is fixedly connected to the meter housing. A limited amount of canting movement is permitted along with the normal rotative movement between the switch rotor and the panel bushing. The switch rotor is connected in a non-precision manner with a socket and a plug. The plug is loose fittingly connected within an opening in the printed circuit board of the meter. A limited amount of canting movement of the plug is capable of occurring with respect to the printed circuit board.

Abstract: A flotation hiking harness having back, side and crotch sections attached to a central buckle and having a shoulder section over the shoulder blades and front sections over the chest which terminate short of the bend line at the waist, the front and shoulder sections providing buoyancy and the front sections being fastened to the central buckle to assist in firmly securing the wearer to a tie line.
