Title: Fuel vapor recovery system
Inventor: LUPOLI PETER J
IPC: F02M25/08
Filed: 1987-09-09
Granted: 1991-10-29
Abstract: FUEL VAPOR RECOVERY SYSTEM                       ABSTRACT    A fuel vapor recovery canister having a housing including an outer wall with spaced-apart vapor ports.          Adsorbent material in the housing absorbs and stores fuel vapors entering one vapor port, or under other circumstances releases such vapors for exit through one of the ports. In one embodiment the housing has in-terleaved baffle plates between the ports, which force vapors entering one port to flow along a serpentine path, giving maximum exposure of the vapor to the adsorbent material. In a second embodiment, a helical partition is provided, similarly forcing vapor flow to occur along a serpentine path. The advantage of the present invention over the devices of the prior art is that improved efficiency is achieved, by maximizing exposure of a larger number of granules of adsorbent material.

Title: Display device
Inventor: GROSSE MAURICE
IPC: G09F11/32
Filed: 1988-04-18
Granted: 1992-01-28
Abstract: A B S T R A C T        The invention provides improvements in display devices.          Shaped guide plates 44 positively guide the suspension rods 4 of viewing sheets 3 around a roller 8 when each suspension rod 4 is engaged by cradles 11 carried by electrically-drive chains 10.   A strap 50 that is rendered resilient by the inclusion therein of a spring 53 extends centrally down the rear of the device and prevents successive suspension rods 4 from becoming detached from the cradles 11 in this region.  A gate which includes a stop 55 is provided at the foot of ramps 5 upon which the rods 4 are stacked to ensure that the rods will not become bunched or otherwise entangled on the ramps 5 and that the cradles 11 will positively pick up only one suspension rod 4 at each passage past the  gate.    A time  delay  switch  56  is  associated with  a microswitch 41 and will close to bypass the switch 41, after a predetermined interval of time,so that the drive of the device may  re-start  even  if  the  power  supply to  the  device  had previously been switched off with the microswitch 41 in its open circuit position.  Each rectangular display sheet 3 preferably comprises two layers which are secured to one another at the edges which coincide with the suspension rods 4 and along one of two longitudinal edges.  The other edge is open except for two relatively  short portions  that  are  joined  together  at  its opposite ends whereby webs carrying indicia may be entered between the layers, by appropriate flexing,  and will remain trapped therebetween by the short joined together edge portions of the two layers.

Title: Matched absorptive end choke for microwave applicators
Inventor: SHEN ZHI-YUAN
IPC: H05B6/76
Filed: 1988-07-07
Granted: 1991-11-12
Abstract: ABSTRACT OF THE DISCLOSURE A microwave application chamber including a reactive and absorptive choke is shown and described.   The absorptive choke  is made  of  a material having the same or close dielectric constant as the material being treated so that microwave energy will pass readily from the material being treated into the absorptive choke.   The interface between the absorptive choke and the material being treated is essentially transparent to microwave without reflections. This transparency permits microwave energy to be absorbed in the absorptive choke which otherwise would follow the waveguide created by the material being treated and exit into the environment.
