Title: Dual flush toilet control mechanism
Inventor: HOOSHLEY ROBERT L
IPC: E03D1/14
Filed: 1992-10-05
Abstract: ABSTRACT A dual flush toilet control mechanism includes an operating handle and attached actuating cam, a control arm and a control float arm. When the handle is turned in a first direction, the actuating cam moves the control arm to open fully a conventional toilet tank main valve to its buoyant position. When turned the handle is turned in a second direction, the actuating cam moves the control arm to open partially the main valve to a position wherein it is subject to the suction developed by the water exiting the toilet tank. A control cam on the control float arm maintains the control arm in position to maintain the main valve open against the suction until the water level in the tank drops below a predetermined level. When the float on the control float arm reaches the predetermined water level, the attached control cam allows the control arm to drop and the main valve to close.

Abstract: ABSTRACT   A suspended work platform is disclosed for use with mobile cranes or other lifting devices. A safety line passes through an automatic locking device to prevent the platform from falling should the main crane lifting cable fail. The platform has a floor and a central, upright tube terminating in a spring loaded, telescopic suspension member. The automatic locking device is attached to the tube, with the safety line slidably retained therein. A linkage is coupled between the suspension member and the locking device to release the locking device upon lifting tension being applied to the suspension member by the crane lifting cable. A reel is mounted under the platform floor to take up the safety line as the platform is being raised, and a spring motor biases the reel to maintain tension in the safety line. The locking device  clamps  onto the  safety  line preventing the platform from falling in the absence of lifting tension on the suspension member.

Title: Golf ball core compositions
Inventor: NESBITT R DENNIS
IPC: C08K3/22
Filed: 1992-10-21
Abstract: The present invention is directed to improved polybutadiene compositions suitable for use in molded golf ball core construction. The improved polybutadiene compositions are composed of polypropylene powder resins which have the effect of increasing the hardness of the resulting molded cores without increasing the weight upon daring, thereby allowing for a reduction in the amount of crosslinking agents utilized and increasing the amount of fillers incorporated therein. The addition of the polypropylene powder resins to the core compositions lowers the cost of the molded core, while maintaining the proper weight and compression. The present invention is also directed to golf balls produced utilizing the improved core compositions.      Furthermore, the invention is directed to a method for reducing the amount of crosslinking agents utilized to formulate a core composition through the incorporation of polypropylene powder resins. In addition, a method for decreasing the amount of crosslinking agents and increasing the amount of mineral fillers included in a core composition through the incorporation of polypropylene powder resins is also disclosed.

Title: Downhole instrument power supply system using shunt voltage regulation
Inventor: BAKER DONALD L
IPC: G05F1/613
Filed: 1993-11-12
Abstract: ABSTRACT A downhole power supply system having a variable voltage surface power supply and a downhole shunt voltage regulator between which is disposed in series an energy transducing device. The shunt voltage regulator comprises a current control device which controls the amount of current shunted to the power return line between the series connected energy transducing device and the input to the voltage regulator to maintain a selected voltage at the voltage regulator. The shunt regulator senses the voltage on the power line, compares the sensed voltage to the selected voltage, and controls the shunt current control device to conduct more or less current in the event that the two voltages are not equal. As a result, changing the voltage at the remote power source will change the voltage across the transducing device and the amount of current conducted through it thus changing its output. In the case where the energy transducing device is a lamp, its intensity can be directly controlled by the voltage of the remote power source. Other voltage regulator features include over-voltage protection and reverse polarity protection.

Title: Targeted delivery of genes encoding immunogenic proteins
Inventor: WU GEORGE Y
IPC: C07K16/00
Filed: 1992-05-14
Abstract: Molecular complexes can be used to target a gene encoding an immunogenic protein or polypeptide to a specific cell in vivo.  The gene is incorporated into the target cell, expressed and the gene-encoded product is secreted and an immune response against the immunogenic protein or polypeptide is elicited. The molecular complex comprises an expressible gene encoding a desired immunogenic protein or polypeptide complexed with a carrier of a cell-specific binding agent and a gene-binding agent. The cell-specific binding agent is specific for a cellular surface structure which mediates internalization of ligands by endocytosis. An example is the asialoglycoprotein receptor of hepatocytes. The gene-binding agent is a compound such as a polycation which stably complexes the gene under extracellular conditions and releases the gene under intracellular conditions so that it can function within a cell.  The molecular complex is stable and soluble in physiological fluids and can be used to elicit an immune response against a variety of immunogens in an organism for the purpose of vaccination or for the production of antibodies.

Abstract: In accordance with the present invention, there can be mass produced long-term preservable lunches in a short period of time, because a series of such operations as formation, cleaning, sterilizing, dishing-up, sealing and filling the lunch box with an inert gas are carried out consistently by virtue of the production unit of lunches of the present invention.  Further, because the lunches are allowed to pass through successively the gas chambers filled with the inert gas, no insufficient filling of the lunches with the inert gas will occur.    Further, the lunch boxes can individually be filled with the inert gas when each lunch box is provided with a sealing valve and filled with the inert gas by inserting an inert gas filling tube into said lunch box through the sealing valve.          The film for sealing the lunch boxes is provided thereon with a self-sealing member, and said lunch boxes may individually be filled with the inert gas by inserting the gas filing needle into each lunch box through said self-sealing member.    Furthermore, foodstuffs for which their freshness is required such as vegetables or fruits can be prevented from their deterioration of quality with time when an ethylene gas adsorbing means is arranged in the lunch box.  Such putrefactive foodstuffs as vegetables or fruits may be dished up in the lunch box while maintaining a level of freshness when they are harvested and delivered to lunch producers when they are stored in a bag provided with an ethylene gas adsorbing means and arranged in said lunch box.
