Abstract: An automatic steel ball recollecting apparatus for use in pinball machines comprises a score board, a drive motor, a main frame, a slide board, and steel ball trapping units.

Abstract: Effective support of the head and neck during high impact accidents or rapid or sudden acceleration or deceleration of riders of motorcycles, skimobiles, jet skis and power boats, is provided by a cervical protection system having a gas-filled bag (110) rapidly deployable from a collar (105) disposed around the base of a helmet (101). When deployed, the bag (110) extends to the mid-sternal area anteriorly, to approximately the fourth or fifth thoracic vertebrae posteriorly, and laterally on the shoulders to a point approximately mid-way between the sternomastoid muscle group and the lateral tip of the scapula, and holds the wearer's head in slight extension to mitigate physical harm. Also, a deployable cervical collar which is removably mounted to a helmet. The collar deployable before or after impact.

Abstract: A convenient and easily reassembleable control mechanism for a video game is provided. The control mechanism includes a control rod, a mechanism body, a switch control plate, a plurality of micro switches and an actuator wherein the switch control plate has a central square hole having four defining wall corners from which the control plate is provided with a four outwardly extending grooves adjustably receiving therein four adjustors each of which can project beyond or fully be received in one respective groove so that the actuator can operate one microswitch or two adjacent microswitches at a time.

Abstract: A ticket dispenser capable of effectively preventing additionally withdrawing thereout a ticket is provided.

Abstract: The present invention is a gravimetric procedure for the measurement of solids and/or liquids in a statically dissipated Teflon bag. The procedure enhances the accuracy of presently accepted laboratory methods because the sample container weighs little relative to the sample and the bag is an inert surface which is not activated or contaminated. Solids placed in the Teflon bag can be treated, weighed, and stored in the bag without any sample transfer. Liquids placed in the Teflon bag are treated and weighed without transfer. This procedure has been applied particularly to laboratory procedures for measurement of particulate samples collected from effluent gas streams during environmental testing.

Abstract: An airport landing system includes an airborne transmitter and receiver for transmitting RF energy at a first frequency and receiving RF energy at a second frequency. A stationary RF energy focusing means for focusing received RF energy. At least four receive/transmit modules and at least one RF source module. The RF source module for amplitude modulating and amplifying the received RF energy for retransmission by the receive/transmit modules. The receive/transmit modules having RF energy collector horns physically arranged with at least two vertically disposed horns and two horizontally disposed horns for transmitting at least four relatively high gain powered beams whose patterns cross over at their half power points with the crossover point defining the approach path.

Abstract: Solar apparatus for producing alcohol including a frame portion, a heating portion, a slurry-forming portion, a fermentation portion, a distillation portion, a condensation portion and a drying portion; the heating portion including a plurality of solar panel members, the slurry-forming portion including a hammer mill and a frustoconical section thereunder, the frustoconical section including a tangential liquid inlet opening and a tangential slurry outlet opening, the fermentation portion including a fermentation chamber, a pump disposed adjacent the chamber, inlet and outlet conduits extending between the pump and the bottom of the chamber, the distillation portion including a base section and a face section, the face section including a conduit having a circuitous path, the condensation portion including a first chamber, a second chamber extending downwardly within the first chamber partway down from the top, a spiral conduit disposed within the first chamber, the drying portion including a solar air heati

Abstract: An improved opening closure system utilizing a plurality of curtains supported in a way to cover the opening with alternate embodiments having primary and secondary curtains acting as a thermal siphon and with fan units as a power air destratifier.

Abstract: The invention is an apparatus for collecting and transporting thermal energy as vaporized fluid. The vapor will flow from a heat absorption chamber and through a conduit to a point of use where it is condensed. The heat absorption chamber includes a sump in its lower portion to hold a puddle of fluid. A heat source directed against the chamber vaporizes the fluid therewithin and a replacement fluid supply connects with the chamber to maintain the level of the puddle during vaporization. The chamber of the preferred embodiment of the invention is an elongated heat absorption pipe mounted horizontally to maintain the puddle at the lower portion of the pipe. The heat absorption pipe is mounted in a solar collector to receive concentrated solar energy as from a reflector system.
