An adjustable reciprocating saw has the ability to adjust the orientation of the saw blade in relation to the rest of the tool. The saw blade can pivot about two transverse axes, one parallel with and one perpendicular to the reciprocating motion axis of the saw blade. The portions of the saw's housing which rotate relative to one another are attached with a rotating joint comprising a pin and groove design. Rotation locks selectively prevent rotation of the saw blade about each axis. The rotation locks can be released through simply depressing buttons on the saw. A rear internal bearing increases the durability and decreases the size of the saw. A keyless adjustable shoe is mounted to the saw.

An apparatus for preventing young children from activating a push button switch while allowing adults to activate said button. The apparatus is a semi-rigid child-proof cover or cap for the “home button” or menu button on a personal electronic device or computing tablet. The cap is disposed over the push button switch and prevents young children from pressing it because the strength necessary to bend the semi-rigid material of the cap is beyond that of young children. However, adults have sufficient strength to push the semi-rigid material with enough force that it bends and thus exerts a downward pressure and activates the push button below it. A small hole may also be defined in middle of the cap that allows an adult to use a paperclip or other pointed object to activate the button, while being too small for a young child's finger to pass through and activate the button.

Food nanoemulsion compositions comprising a food safe nonionic surfactant, a hydrophobic food flavorant (e.g., an essential oil), a sugar alcohol kosmotrope, and water. The ratio of the sugar alcohol kosmotrope to the hydrophobic food flavorant is at least 8:1 by weight, and the composition advantageously requires little if any monohydric alcohols for stability and is also free of polyols in addition to the sugar alcohol. Such nanoemulsion compositions are formed from microemulsion concentrates with little or no kinetic energy input. The microemulsion phase inverts to the nanoemulsion upon dilution with additional water. Infinite dilution in water and oil is possible. The high ratio of sugar alcohol to flavorant controls the particle size distribution of the nanoemulsion composition and advantageously alters the organoleptic properties of the nanoemulsion to insert perception of the flavorant near the end of the palatal response.

A child safety buckle used in a child restraint includes structural support and selected materials to resist deformation or failure when subjected to impact or compressive forces. The buckle may have a child resistant feature that is more tolerant to impact or compressive forces due to the structural support and material selection. The structure may include thickened walls or added arcuate portions or ribs. The material can be impact modified nylon to improve durability while resisting deformation and cracking. The resulting buckle design is more robust in harsh environments, while providing consistent operation for restraining a child.

Coating-type compositions and methods using the compositions for making new forms of chip-type and other fried or baked snack and / or convenience food items, including sweet goods, which are externally coated with and / or directly incorporate the compositions into their dough matrix. The compositions significantly increase the crispness and tensile strength of the food item after it is cooked with them in place, and so change both the organoleptic and storage qualities of the foods as to provide a new form of the underlying product. On sweet goods, the coating provides a stabilizing surface barrier for sugar toppings which prevents them from becoming tacky, moist, or wet, while adding crispness at the surface and simultaneously reducing moisture loss from the baked dough, greatly retarding staling. The coatings also provide a new and better way of applying seasonings and colorings to food products.
