Abstract: A vehicular-themed ornamental mailbox includes a storage compartment, a lid, a speaker module, a first ornamentation, a second ornamentation, a third ornamentation, and a fourth ornamentation. The storage compartment includes a top panel, a rear panel, a bottom panel, a left panel, and a right panel thus completing an internal storage area. The lid is hingedly connected to the bottom panel so that the storage area can be closed. The speaker module is connected to the storage compartment and provides a specific sound effect when the lid is opened. The first ornamentation is removably mounted to the top panel. The second ornamentation is removably mounted to the left panel. The third ornamentation is removably mounted to the right panel. The fourth ornamentation is removably mounted to the lid. All four aforementioned ornamentations provide a decorative-theme for the storage compartment.

Abstract: A method and apparatus to implement a trolling device. The trolling device can assist maritime sports fishermen in defining the actual water depth and/or water temperature of the location at which a lure is situated in troll. The readings from the device enable an angler to adjust variables such as boat speed, length of line deployed and ballast weight to adjust to desired depth. The device comprises a temperature sensor, a pressure sensor, a micro-controller chip, a printed circuit board, an LCD display, and a cycle switch, all housed within a dense metal (for ballast), water-proof body designed specifically for deep marine submersion and in-line trolling. The device has a pre-programmed data-logging algorithm that is activated by a fisherman via a magnetic controlled reed switch prior to letting out trolling line with the device set in-line to the trolling gear. Upon retrieving the device, the fisherman can view the data to place or reset the trolling lures/rigs, as necessary, at the appropriate zone.

Abstract: A light cover has a transparent element manufactured from polycarbonate and an infrared filter angled so as to reflect infrared radiation emitted from a light source way from both the transparent element and the light source.

Abstract: The plunger of a baler for making parallelepiped bales is driven by an extensible and retractable hydraulic actuator that is connected for oscillating a link forming a crank coupled to the plunger by a connecting link. The dimensions and locations of the crank and connecting link relative to the hydraulic actuator results in the plunger being moved in the baling chamber through a distance which is about twice the stroke of the actuator when the plunger is moved from a fully retracted position, at one side of an inlet used for introducing crop into the chamber, to a fully extended position at an opposite side of the inlet from the fully retracted position.

Abstract: The present invention relates to novel compounds of the formula ##STR1## wherein R.sub.1 is an alkyl group, M.sup.+ is a cation, R.sub.2 is an alkylene oxide and n is an integer from 1 to 4. Surfactant compositions containing these novel compounds, the process of preparing these novel compounds as well as the methods of using these surfactant compounds in enhanced oil recovery, as emulsifiers, in emulsion polymerization, as hydrotropes, in foamed drilling fluids, as dye carriers, as textile detergents, as foaming agents for concrete formation and as fiber lubricants are also disclosed.
