Title: Pneumatic starter for internal combustion engine
Inventor: KRISTOF JOHN J
IPC: F02N99/00
Filed: 1986-09-24
Granted: 1994-03-29
Abstract: PNEUMATIC STARTER FOR INTERNAL COMBUSTION ENGINE     Abstract of the Disclosure A starter arrangement for an engine includes a fluid actuated rotary vane motor which is adapted to engage an associated engine. The rotary motor has a plurality of blades or vanes with each of the blades being made from a fiber reinforced plastic material to reduce friction.  A sleeve, in which the rotary motor is positioned, has on its inner surface a hard metallic coating to reduce friction.  A relay valve member selectively provides a pressurized operating fluid to the rotary motor.  The blade material and the sleeve inner surface coating cooperate to enable the vane motor, when it is actuated by the relay valve member, to rotate in the sleeve with a minimum of friction thereby obviating the need for a lubricating agent.

Title: Vehicle restraint utilizing a fluid cylinder
Inventor: HAGEMAN MARTIN P
IPC: B65G69/00
Filed: 1986-10-21
Granted: 1991-04-09
Abstract: Abstract of the Disclosure An improved vehicle restraint for preventing movement of a vehicle, such as a truck away from a loading dock during a loading operation.  The vehicle restraint includes a guide frame mounted on the front face of the loading dock and a hook is disposed to move vertically on the guide frame between a lower inopera-tive position and an upper operative position where the hook engages an abutment on the vehicle.  The hook is moved between the inoperative and operative positions by a fluid cylinder assembly, including a cylinder which is disposed in a recess in the driveway adjacent the loading dock, and the piston rod of the fluid cylinder assembly is connected to the hook.  By intro-ducing fluid into the lower end of the cylinder, the piston rod will be extended to move the hook to the operative position.  The compressible nature of the fluid in the cylinder enables the  hook to follow rising and falling of the truck bed during the loading operation.

Abstract: DISPENSING CONTAINERS              ABSTRACT OF THE DISCLOSURE      Dispensing containers are described in which a metering chamber for the contents of a fluid container is mounted in the neck of the container. Openings intermediate the height of the chamber allow it to be put in communication with the container interior by a rotary movement, e.g. applied to an external closure cap. When the closure cap is rotated to open the chamber to the container interior it also adopts a sealing position preventing the escape of any of the contents. The space in the chamber above the apertures is greater than that below.          Sufficient fluid can be admitted to the chamber by inverting the container, therefore, to ensure that the lower space is completely filled when the container is again turned upright. Reverse rotation closes the openings to isolate the metered fluid from the main volume of the container and can also open the chamber to the exterior to allow the metered quantity to be dispensed.

Abstract: Abstract An amplifier having a resonator coupled between input and output terminals thereof supplies a dot clock signal to a character generator in a television receiver. A feedback control circuit supplies DC bias to the resonator during blanking intervals that preceed lines of characters to be displayed to ensure a consistent starting phase for oscillations, removes the DC bias and supplies operating power to the amplifier during a portion of the active video period of each displayed line for sustaining the oscillations and automatically inhibits the supply of amplifier power at the end of each active line of characters to thereby provide three oscillator operating modes of PRIMED, RUNNING and OFF so as to minimize overall power consumption for the oscillator for each field of displayed characters.

Title: Method for restraining vibration of a building and structure therefor
Inventor: SATO TAKANORI
IPC: F16F15/023
Filed: 1988-04-08
Granted: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE       The present invention provides a vibration  restraining structure   comprising  a pair of wall  members  defining  an inner  space  therebetween, separation walls  separating  the inner  space  into  chambers, and a liquid  retained  in  the chambers and having a free surface.            The liquid retained in the chambers slosh as the building  vibrates.  Vibrational energy of  the  building  is transferred to the liquid and generates sloshing thereof.  As a result, vibration of the building is restrained.  Vibration of the building is restrained most effectively when a natural frequency of the sloshing coincides with a natural  frequency of the structure. In other words, the building and the liquid form   a  unitary  oscillating  system,  and  a   fundamental vibration  mode  of  the system is a  mode  wherein  sloshing occurs together with a displacement of the building.     The  method  for restraining vibration  of  a  building comprises a step of providing the above-mentioned  structures at locations where the modal displacement of the building  is significant.

Granted: 1994-06-21
Abstract: Abstract of the Disclosure An existing metallic tank with a corroded bottom is improved by replacing the original bottom with a new bottom above the original, and using the original tank bottom to cathodically protect the new tank bottom.  A closed loop of material is removed from the original bottom close to the perimeter thereof, thus electrically isolating the tank from the remainder of the original bottom.  An insulated cable is connected to the remainder of the original bottom, and an electrically insulative medium such as polyethylene tape is applied to the inside surface of the remainder of the original bottom in an unbroken pattern which includes the location where the cable is connected, thus shielding portions of the remainder under the insulative medium from being anodically sacrificed.  This allows the shielded portions to function as current headers to carry current to the unshielded portions of the remainder of the original tank bottom.  Fill material is placed above the original bottom, and a new metallic bottom is installed above the fill material, in electrical communication with the rest of the original tank.  A direct current is then impressed between the insulated cable and the rest of the original tank, with the insulated cable being positive.
