Patent CA-2038824-A1 (CA)
Title: Combination process for hydrogenation and isomerization of benzene- and paraffin-containing feedstocks
Inventor: LOW CHI-CHU D
IPC: C07C5/27
Filed: 1991-03-21
Abstract: The benzene content in a gasoline pool is reduced by a process that hydrogenates a benzene-containing isomerization zone feedstream. In addition to reducing the benzene concentration, the hydrogenation zone is also used to heat the isomerization zone feed and thereby eliminate the need for an isomerization zone heater. The process employs mild saturation conditions which eliminates hydrocracking and prevents the loss of isoparaffin yield. Additional cyclic hydrocarbons produced by the saturation of benzene can be processed in the isomerization zone for ring opening to increase the available paraffinic feedstock or the isomerization zone can be operated to pass the cyclic hydrocarbons through to a product recovery section.

Title: Fuel system of an internal combustion engine
Inventor: KARNITSKY VIKTOR V
IPC: F02B3/06
Filed: 1991-04-29
Abstract: FUEL SYSTEM OF AN INTERNAL COMBUSTION ENGINE Abstract A fuel system comprises a diesel fuel feeding line communicating by one end with a fuel tank and by the other end with a high pressure fuel pump in turn commu-nicating with engine cylinders connected  to an air feed-ing line, and a gas feeding line whose one end is con-nected to a gas source and the other end is connected to a Venturi tube communicating with the air feeding line. A pedal is operatively connected to a rack of the pump and to a gate provided in the gas feeding line, The fuel system is further provided with a sole-noid for limiting the movement of the rack of the pump to one of the extreme  positions "diesel fuel" or "gas fuel" electrically connected to a switch. The switch is electrically connected to a solenoid-operated valve positioned in the gas feeding line. This line also includes a gas pressure regulator. The rack is operati-vely connected to a  pneumomechanical valve connected to the Venturi tube and to the gas pressure regulator.     The proposed fuel system can be used in wheeled vehicles, such as trucks 3 to 120 tons in load-carrying capacity, and can ensure a 70 to 80% reduction the amount of diesel fuel consumed.

Title: Vacuum distribution apparatus and method for flat bed screen printing press
Inventor: BUBLEY HENRY J
IPC: B41F15/20
Filed: 1991-05-01
Abstract: ABSTRACT      Disclosed is a vacuum distribution system for use with flat bed screen printing presses which provides a vacuum to hold printed articles securely to their respective flat beds during multiple printing operations. A stationary, annular vacuum ring is placed in direct contact with a rotating turntable which supports the flat beds upon which the articles are secured.  The turntable is provided with a plurality of apertures therein, each in alignment with the vacuum ring, and each having conduit extending from the aperture to a respective flat bed upon which articles are secured and transported. Thus, by inducing a vacuum in the stationary vacuum ring, a vacuum will be induced at each of the respective flat beds for securing articles thereto in a stationary position, regardless of the rotational position of the turntable.

Title: Catch mechanisms
Inventor: BAYLEY BRIAN
IPC: E05B65/00
Filed: 1991-06-24
Abstract: ABSTRACT OF THE DISCLOSURE     IMPROVEMENTS RELATING TO CUPBOARD CATCH                          MECHANISMS     A safety catch mechanism is provided which allows limited  opening  of  a  cupboard,  drawer,  or  other storage unit.   When the catch is engaged,  a child cannot  gain access  to the contents of the storage unit, but an adult can release the safety mechanism when  it  is  in  its  partially  open  position  thus disengaging the catch and gaining access.  The safety catch of the invention includes resilient engagement means designed to retract to a non-protruding position relative to the storage unit portion on which it is mounted when it is released from engagement.   The absence of protruding hooks or spikes when the storage unit  is  open  enhances  the  safety  of  the  catch mechanism.
