Abstract: A B S T R A C T        For fluid treatment, a flexible collapsible structure is provided which consists of stacked horizontal partition walls formed from pairs of sheets of non-woven fabric material, such as felt heat-joined by plastic coatings on their inner surfaces and disposed in vertically-spaced parallel arrangement and sealed at their sides by accordion-folded sheets of flexible collapsible material.  The paired sheets contain ports which are offset relatively to one another in successive sheets   The paired fabric sheets and their plastic-coated inner surfaces are provided with openings to form cells with which the ports communicate, these openings being so arranged that a multi-columned collapsible structure of parallel cellular formation results, with independent zigzag paths between top and bottom of each cellular column. Thus, heat transfer is greatly enhanced by the retarded flow of the hot water horizontally across the liquid-absorbing fibrous surfaces of the felt on the exposed outer sides of the partition walls.  The structure is prefer-ably suspended from an external framework, the suspension caus-ing the laminated partition walls to separate into parallel columns of laterally-interfitting vertically-staggered cells.

Abstract: ABSTRACT OF THE DISCLOSURE Frequency division of microwave signals may be done using hetero-dyne conversion but there are limits to the ultimate instantaneous band-with that can be down-converted using this method ant any frequency aberra-tions of the local oscillator show up at the output.  It is also known to down-converst microwave signals by using a varactor divide-by-two system.          However, to divide by factors greater than two, these dividers must be cascaded which results in losses that must be compensated by amplifiers.  The present invention alleviates the foregoing problems by providing a single-stage analog microwave frequency divider which will divide microwave sig-nals by four.  The divider comprises a substrate having an input micro-strip transmission line capacitively coupled to a resonator formed of first snt second spaced apart parallel microstrip transmission lines of pre-determined length.  One end of each of these lines are joined together by a transverse microstrip transmission line and the other end of each of these lines is connected to substrate ground via an associated varactor tiode.  The first and second microstrip transmission lines are electromag-netically coupled to third and fourth microstrip transmission lines and the third and fourth microstrip transmission lines are connected in series to a stripline balun comprising an output of the divider.

Title: Surface wiping implement
Inventor: EVANS STEPHEN F
IPC: A47L1/15
Filed: 1978-10-31
Granted: 1982-04-27
Abstract: Abstract A surface wiping implement is disclosed which is capable of effectively drying a surface.  The surface wiping imple-ment has an absorbent core encased in an outer layer which is incompressible.  The porosity, thickness, and liquid retention characteristics of the outer layer permit rapid penetration of primary drops of liquid into the absorbent core, while secondary drops of liquid are strongly attracted to and held at the interstices of the outer layer.  The combined effects of the core and the outer layer remove liquid from the surface and prevent a redepositing of the removed liquid, thus permitting the surface wiping implement to remove all but the very small droplets of liquid which will evaporate in 15 seconds or less without spotting, streaking, or filming the surface.

Abstract: DETECTION CIRCUIT FOR A BI-DIRECTIONAL, SELF-IMAGING GRATING DETECTOR                              Abstract An optical position sensing apparatus utilizing a grating having two sets of opaque and transparent lines thereon, one of the sets being off-set from the other is associated with a source-detector assembly, the source and detector assembly including pairs of light sources and detection devices with at least one of the devices of one of the pairs being aligned with one set of light interrupting opaque lines and the other device of the pair being aligned with the other set of light interrupting opaque lines so that the image of the area illumi-nated by the opposing source is projected back upon the area of the grating in front of its respective detector as by an imaging reflect surface, preferably a concave mirror.            Because the signal  from the detectors varies in time and magnitude, and there is DC leakage from the detectors, it is necessary to estab-lish a threshold detection voltage to insure a proper signal output wave form for both position and direction of relative motion sensing. This is accomplished by generating first and second voltage references to follow the peak and valley of the signal and generating the thres-hold level detection voltage which may then be compared to the input signal to create a predetermined wave form having a predetermined frequency relationship to the input signal.
