Abstract: VENTED BATTERY CAP                  Abstract of the Disclosure A vented cap for a multiple cell storage battery com-prises a base member having a plurality of integrally molded vent plug portions adapted to fit into individual filler wells of the battery and a cover member which snaps in place over the base member to form a chamber for gas egressing from the battery.          The base member includes interior walls and a plurality of in-tegrally molded latch members which engage the rim of the cover member to secure the cover member in abutting relationship to the interior walls.  The interior walls are dimensioned to space the rim of the cover member from the rim of the base member where-by a continuous vent slot is formed around the periphery of the cap which allows battery gas to escape from the chamber with wide dispersion while inhibiting inward propagation of an externally generated flame.  The latch members may be alternatively provided on the cover member so as to engage the rim of the base member, and the vented cap may also be constructed in single-cell form having a single vent plug portion for insertion into a single battery filler well.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of converting non-harmonic acceleration of linear reciprocal motion into generally sinusoidal acceler-ation.  In this method, non-harmonic acceleration of the linear reciprocal motion of a driving means is transformed into complementary rotary motion, and the complementary rotary motion is translated into generally sinusoidal accelerations by conjointly moving an articulated means and drivingly interconnecting it with a linear reciprocating driven means.          Apparatus for converting non-harmonic accelera-tion for linear reciprocal motion into generally sinusoidal acceleration is also disclosed.

Abstract: 218-13.01 ABSTRACT OF THE DISCLOSURE           A sump motor is mounted in a section of pipe.  The motor is a standard motor having special caps at each end of the motor shell and with the shell forming a waterproof en-closure.  The caps have radially extending spacers extending out to the pipe.  At each end of the pipe are reducers, the internal diameter of the small ends of which correspond to the external diameter of another, smaller standard pipe size.  At the bottom a piece of pipe of the smaller size extends inwardly of the reducer to a location in juxtaposition to the pump im-peller.  Various connections and mounting arrangements may be made using standard sizes of pipe.  In one embodiment the pump is mounted on a vertical track and positioned above a sump.         When the water rises to a level in the sump at which pumping should commence, the motor is energized and the pump is lowered along the track into the sump.

Abstract: GAUGING SYSTEM PROVIDING REMOTE READOUT OF LIQUID LEVELS IN GASOLINE STORAGE TANKS Abstract: A controller at a monitor location generates interrogate signals which are transmitted over a telephone line to a transmitting unit associated with a plurality of underground gasoline storage tanks, The transmitting unit responds to the interrogate signals to selectively couple pressure sensing lines to a pressure sensing trans-ducer. Each line extends into a different one of the storage tanks and provides a pressure which is proportional to the depth of the liquid in the corresponding tank. As each line is coupled to the transducer in sequence, the transducer provides an output voltage corresponding to the sensed pressure. The output voltage controls a trans-mitter of the transmitting unit which generates an audio signal related in frequency to the sensed pressure, and the frequency signal is transmitted over the telephone line to the controller which detects and decodes the frequency signal and controls a display unit to provide a visual display of the liquid level in the selected tank.

Abstract: Abstract of the Disclosure The air hammer is of the type employing a body having a first portion with a central bore and a piston reciprocable in the bore by pressurized air under control of an automatic valve.  The body has a second or muffler portion which embraces the first portion and is operative to muffle the noise created by exhaust air from the bore.  The muffler portion is provided with pressurized air passage means through which the pressurized air must pass for causing operation of the piston.  The passage means are so arranged that removal of the muffler portion from the body disrupts the supply of pressurized air to the piston and thereby renders the hammer inoperative.  Headers are provided on the ends of the body and are drawn tightly against the ends of the muffler portion by tie bolts which extend through through-passages, respectively, in the muffler portion.  The through-passages are of larger diameter than the associated bolts, and the clearance spaces between the through-passages and their associated bolt provide a portion of said passage means, and act to deliver live air to the piston, to accumulate pressurized air, and to deliver pressurized air for actuating the automatic valve.

Abstract: ABSTRACT OF THE DISCLOSURE         A pressure control valve for use in vehicle hydraulic diagonal split brake systems. The valve includes two valve pistons which operate to limit the fluid pressure delivered to the rear wheel brakes relative to that delivered to the front wheel brakes.          The valve also includes a failure warning mechanism having a switch actuating piston.  In the event of a failure in one branch of the diagonal split brake system, the switch actuating piston operates to simul-taneously preclude the two valve pistons from limiting the rear wheel brake pressure so that the rear wheel brake in the unfailed branch of the brake system can develop the maximum braking effort for vehicle emergency braking.

Title: Anhydrous gasohol from aqueous alcohol and  whole gasoline through dehydration column
Inventor: CHAMBERS JOHN M
IPC: C10L1/182
Filed: 1979-11-08
Granted: 1982-09-14
Abstract: Abstract of the Disclosure There is provided a process for making anhydrous alcohol denatured with gasoline for ready mixing with additional gasoline to make gasohol and in which aqueous alcohol is intro-duced into a dehydration drying column along with gasoline.  The alcohol, containing gasoline, flows into the lower zone of the drying column and is recovered as a substantially non-aqueous alcohol-gasoline mixture which may be classified as completely denatured alcohol.  The rising vapors of the  gasoline entrain the water and some alcohol as azeotropes which flow out the top of the column as vapors which are condensed to form a gasoline layer which is returned to the column and a water layer which is removed. Additional water is also removed by decantation on the top several trays of the drying column where it is present as a separate liquid phase.  The process also includes utilizing the heat to strip the alcohol from dilute fermented wort for the re-covery and reconcentration of the alcohol in the water layers re-cycled from the drying column while preventing any gasoline from contaminating the fermented feed product and insuring that gasoline is present as a contaminent in all alcoholic streams.  Provision is also made to insure that all light ends in the incoming gasoline are contained in the alcohol-gasoline product.
