Abstract: A small box with a keyed lock into which an electrical plug is placed and then locked for preventing the insertion of the electrical appliance plug into a wall socket comprises a plastic box (A) with a front sliding door (B) and a keyed cam lock (D).

Abstract: An organic, fresh-smelling fertilizer product is produced by collecting llama pellets from llamas that have preferably been fed only alfalfa hay with grain supplements. The pellets are first dried by means of a relatively slow process that enables them to harden as pellets rather than fragment, and they are then ground to produce a particulate mass such as powder, granulates or pellet-sized particles which has an alfalfa-like scent and is a very effective fertilizer.

Abstract: A pedal actuated brake system is provided for retrofitting onto a multi-speed bicycle so that back pedaling applies the brakes. A decoupler disengages the front chain sprocket from the crank when reverse-rotated to prevent application of the brakes when the bike backs up. The system may be used in addition to or in place of the existing hand brakes.

Abstract: A trainer designed primarily for dogs but no doubt useful for other small pets has a wide panel surrounded by a continuous peripheral lip which seats one or more layers of newspaper. A pet tether connected centrally of the panel is attached at its distal end to the collar of the pet, preventing the pet from escaping beyond the confines of the panel so that the pet develops the habit of relieving itself on the newspapers in the pet trainer.

Abstract: A method of testing the reflectivity of RF absorber materials utilizes an elongated chamber lined with RF absorber material and having a source antenna at one end, with the other end terminating in either a "short circuit", or a piece of RF absorber material which is to be tested. A probe antenna is moved along the axis of the chamber and the standing wave created by the source antenna and the reflection from the other end is recorded, first with the short circuit condition, and then with the test sample in place, and the results are compared to yield a figure for the reflectivity of the test sample.

Abstract: An impermeable, vibrating pillow is provided with suction cups so that it may be conveniently bonded temporarily to the surface of a bathtub, jacuzzi or the like to support the neck, feet, or other regions of the body and provide a gentle, relaxing massage by virtue of the vibrator, which is embedded in the foam portion of the cushion and is actuated through the resilient cover by a pressure switch which is preferably mounted just inside one end of the cushion.

Abstract: A delay valve is attached to a fire hydrant and interposed between the hydrant and the hose and restricts the otherwise high flow and high pressure of the hydrant to a small fraction of the normal flow and pressure until the hose is filled up, at which point the valve opens fully so that the hose and hydrant are fully operational.

Abstract: A means and method are provided for harvesting field crops such as watermelon, tomatoes, cabbages, brocolli, cauliflower, cucumbers, spinach, onions, red beets, turnips, squash, mixed melons, and others. The system utilizes about six identical or very similar trucks, one of which is modified to act as the harvesting truck by the attachment of a series of conveyors and hydraulic structure whereby laterally directed wing conveyors extend out over the fields and convey crops deposited thereon through other conveying mechanism up to the truck bed where it is put directly into crop shipping containers which are palletized on a roller grid attached to the truck bed. The trucks other than the harvesting truck act as shuttle trucks and back up in sequence to the rear of the harvesting truck and are coupled to it, subsequent to which a winch and T-bar are extended from the shuttle truck into the harvesting truck to draw, in a single pull, all of the filled containers onto a roller grid in the bed of the shuttle truck.
