Title: Chromatographic column terminator element and assembly
IPC: G01N30/60
Filed: 1983-05-18
Abstract: A porous sintered metal chromatographic column terminator element (38) comprises a relatively low density central disc portion (48), an integral relatively high density rim portion (44) peripherally circumscribing the central portion (48) and an interface zone (50) that integrally joins the rim and central portions (48,44). The relatively flat faces (52, 54 and 56, 58 respectively) of the rim and central portions (48,44) are essentially coplanar but are separated and delineated by a channel (60,62) at the surface of the interface zone (50) intermediate said coplanar faces (52, 54 and 56, 58) permeability ratio between the central disc portion (48) and the rim portion (44) is of at least 31. Additionally, the central portion exhibits a density up to about 70 percent of the density of solid material of the same composition while the density of the rim portion is greater than that of the central portion and is up to about 95 percent of that of solid material of the same composition.

Abstract: A machine for manufacturing foam building blocks (39) 
and the like wherein a plurality of two-piece forming molds 
(21) are continuously moved by a conveyor mechanism along 
a closed path-of-travel (22) is disclosed. Filling, curing and 
injection stations (31, 32 and 33) are located along the path-­
of-travel (22). As a mold (21) enters the filling station (31), the 
nozzle (37) of a foam gun (35) enters a hole (34) in the top of the 
mold (21) and moves with the mold (21) as that mold con­
tinues to move along the path-of-travel (22). At the end of the 
filling station (31), after the foam gun (35) has injected a 
suitable amount of resin, curing and foaming agent materials 
into the mold (21), the nozzle (37) rises from the hole (34). 
Thereafter, a cap-latch (36) is moved into a hole closed posi­
tion, in addition to closing the hole (34), the cap-latch (36) 
forms one of two latches that latch the two mold pieces (21a 
and 21b) together. The other latch (38) is located on the oppo­
site side of the forming molds (21). After leaving the filling 
station (31), the forming molds pass through the curing sta­
tion (32) where they are heated to a suitable temperature. 
After leaving the curing station (32), the forming molds (21) 
enter the ejection station (33) where the latches (36, 38) are 
opened, the forming mold pieces (21a and 21b) are split apart 
and the finished foam block (39) is ejected. Then, the forming 
mold pieces (21a and 21b) are brought back together and the 
latch (38) is closed. Thereafter, the forming molds (21) are 
moved to the filling station (31) and the cycle is repeated.

Title: Electrodes made with disordered active material and methods of making the same
IPC: H01M10/04
Filed: 1984-10-26
Abstract: The present invention provides an electrode (15, 115, 165, 225) which uses a disordered active material (15, 115, 165, 225) preferably formed by rapid solidification. The active material does not need a binder to be used as an electrode, and thus, is considered self-supporting. The material also is substantially nonporous or impermeable to an electrolyte and when used as an electrode exhibits an increase in cell capacity with improved resistance to corrosion. An electrochemical cell (10, 85, 100, 150, 200) and battery (75) utilizing an electrode of the present invention provides greatly improved cycle life and energy density without a significant decrease in cell capacity. Methods of making the electrode by rapidly solidifying a disordered material are also included. A method of assembling an electrochemical cell using a self-supporting electrode includes the step of producing a disordered active material and aligning the material in a predetermined position in a cell casing.

Abstract: A mechanically timed ignition system for an internal 
combustion engine has a variable reluctance transducer (10) 
mechanically operated by the engine to produce an output 
waveform having zero crossings coinciding with the desired 
instants of sparks.  
     A comparator means (A₁, A₂) at the input of an integrated 
ignition control circuit (11) is connected to a winding of the 
transducer (10). The i.c. output point ("2"), which controls a 
semiconductor switch (13) connecting an ignition coil (14) 
across a supply, is connected by a C-R feedback path (C₄, R₉) 
to the input of the comparator means, to provide transient 
positive feedback, which is effective at cranking speed to 
provide improved rejection of low level audio frequency in­
terference signals.
