Title: Foldable playyard
Inventor: DILLNER JAMES M
IPC: A63G31/00
Filed: 1988-02-23
Granted: 1990-12-04
Abstract: FOLDABLE PLAYYARD Abstract Of The Disclosure Foldable playyard comprising upper and lower frame assemblies.  The lower frame assembly comprises a unitary central  hub member,  corner leg connecting members preferably in the form of support feet, and hub legs diverging radially outwardly from the hub member.   The upper frame assembly includes corner rail connecting members and pairs of in-line side rails which are pivotably coupled at their outer ends to adjacent corner rail connecting members and at their inner ends to a medial rail connecting member.  Corner legs interconnect and are freely coupled to the upper and lower frame assemblies.   In one embodiment, the medial rail connecting member houses a hand releasable latch mechanism.   In other embodiments, a hand releasable latch mechanism is rotatable with the side rails between latched and released positions.  When the playyard is erected, the hub legs and side rails maintain the corner legs upstanding in a spread configuration.   When the hub legs and side rails are collapsed, they draw the corner legs  towards  the hub member  and  into a compact configuration.  For safety purposes, the rail pairs cannot be collapsed unless the latch mechanism is released.   A discrete foldable floor having rigid sections  is foldable into a box-shape for carrying the collapsed playyard.

Title: Isoelectric focusing process and a means for carrying  out said process
Inventor: FAUPEL DANIEL M
IPC: B01D57/02
Filed: 1988-04-08
Granted: 1995-06-06
Abstract: Described are an isoelectric focusing electrophoretic process and an apparatus for the separation and purification of an amphoteric or neutral chemical compound from one or more electrically charged chemical com-pound(s), e.g. contaminating proteins and salts. The apparatus comprises a flow chamber (8) which is connected via a cylinder (5) to the cathodic chamber (3) and via another cylinder (12) to the anodic chamber (14). The mixture to be separated is present within a hydraulic flow in the flow chamber (8). Cylinders (5) and (12) contain immobilized pH-gradients or amphoteric isoelectric pH-membranes. Each of said pH-gradients and pH-membranes has conductivity and both buffering and titrant capacity in its pH-interval. The extremities of said gradients or pH-membranes forming the ceiling and the floor of said flow chamber (8) have iso-electric points equal to or just higher and just lower than the iso-electric point of said amphoteric compound of interest which is kept at its isoelectric point in the hydraulic flow and does not enter said pH-gradients and pH-membranes. Contrary thereto the electrically charged chemical compounds, e.g. the contaminating proteins and salts, are driven by an electric field into said pH-gradients or via said pH-gradients or pH-membranes into the electrolyte reservoirs (3) and (14). In respect to the prior art, the described process has the advantage that the desired compound need not be detected and extracted from any matrix, e.g. from said pH-gradients, and that the recovery and purity of the desired compound is higher.

Granted: 1993-04-06
Abstract: MICROWAVE LANDING SYSTEM WITH FAIL-SOFT SWITCHING OF DUAL TRANSMITTERS, BEAM STEERING AND SECTOR ANTENNAS            ABSTRACT OF THE DISCLOSURE        An MLS system having redundant subsystems. Dual signal sources feed dual power dividers.  A first switch array selects the power divider to be used and provides the selected signals to an array of phase shifters.  A second switch array provides the phase shifted signal, which may be amplified, to either a primary array having elements for radiating a scanning beam or a recombining network having outputs connected to auxiliary antennas.  A third switch array provides control signals to the array of phase shifters from either a main beam steering unit or a standby beam steering unit.  Alternatively, the dual signal sources feed a single power divider through a circulator. Duplicate auxiliary antennas may be used with antenna switches located before the power dividers or circulator for selectively providing the signals to the auxiliary antennas instead of the primary array.

Abstract: Abstract of the Disclosure A  newspaper  dispenser includes a housing with an upwardly biased  platform therein for supporting a stack of newspapers.  A scoop  assembly  which dispenses a single newspaper at a time, is mounted  in  the  housing  and  includes a pusher arm and a scoop connected  to  reciprocating  rotatable drive shaft.  Rotation of the  shaft  in  one direction causes the pusher arm to drop onto the  top  newspaper  and  push  the  top  layer rearwardly, while simultaneously  dropping  a  scoop in front of the folded edge of the  newspaper.   Rotation of the shaft in the opposite direction causes  the scoop to slide under the paper, causes the pusher arm to  pull  the  paper onto the scoop, and causes the pusher arm to raise  off of the paper as the scoop tilts to drop the paper down a  chute  for dispensing.  A rotatable handle is connected to the scoop  assembly  via a series of gears and rack and drive gear to operate the reciprocating cycle to dispense a paper.

Title: Pressure venting system for lens cases
Inventor: KANNER ROWLAND WM
IPC: G02C13/00
Filed: 1989-06-13
Granted: 1994-08-23
Abstract: Abstract of the Invention An appliance for disinfecting contact lenses wherein the lenses are disposed within a lens disinfecting solution which produces a gas during the disinfecting action. The appliance has a container body with a lens holder for supporting a pair of contact lenses within the container and a removable cap with a vent means which seals the container to prevent contamination while permitting the venting of gases developed during the disinfecting action.  The vent consists of a post positioned in a bore such that the post does not obstruct passage of gas from the inside of the container and a resiliently deflectable apertured diaphragm covering the bore.  The diaphragm is securely held in place over and around the post whereby the post protrudes through the aperture in the diaphragm.  The aperture in the diaphragm deflects away from the post when the pressure within the container exceeds a threshold pressure.  Once the pressure within the container is equalized with the ambience, the diaphragm resiliently deflects to close the vent thereby protecting the contents of the container from contamination.  Additionally, the apertured diaphragm scrapes small particles of proteinaceous material and other matter off of the post.  Such matter is deposited on the post by the exhausting gas and, if not for the scraping action, would build up on the post rendering the vent useless.

Abstract: Process for converting raw soybean materials into soybean oil and soybean meal without flaking the soybeans during the process is disclosed. The soybeans are cracked into a plurality of kernel portions and hull portions.  The cracked kernel portions are then pulverized in a hammermill or the like and are then conveyed to a screw-type conveyor wherein steam is injected through the screw conveyor housing.  Breaker pins extend radially inwardly from the screw housing and are located between rotating screw flights so as to provide a working, sheering action on the steam-treated particles as they are conveyed by the screw conveyor.  A die plate with apertures therein is disposed at the downstream portion of the screw conveyor and in fluid-tight relationship therewith to form back pressure.  The steam-treated particles exit the die plate through the apertures in the form of pellets.
