Patent EP-0317138-A2 (EP)
Inventor: CHANG CHING-JEN
IPC: A61L15/60
Filed: 1988-11-04
Abstract: Superabsorbent polymeric compositions comprise a water insoluble hydrogel forming copolymer. They are derived from a first hydrophilic monomer which is acrylic acid or a water soluble salt thereof and second hydrophilic monomer which can be a soluble salt of  beta -acryloxypropionic acid. This reduces the phase separation of the monomer mixture which otherwise occurs. Preferably, the pH of the aqueous monomer solution is adjusted to exclude free acid. The monomer mixture may be coated onto a heated surface to polymerize the monomer and dry the resulting hydrogel. Free acid thermal degradation products are avoided and the superabsorbent product has greater absorption capacity than acrylate homopolymer.

Abstract: In a copier, automatically providing tabbed sheets in the output of the copy sheets (26) of the copier, with an integral, on-line, copy sheet tab cutting system (30). Selectably varying the tab cutting position and cut tab size provides sequentially varied tabs (28). A selected tab may be cut on any selected sheet being fed through the regular copy sheet (paper) path of a xerographic or other copier or printer. This may be done by temporarily stopping and registering (32, 34) the leading edge of the selected sheet, and then shear cutting off the untabbed areas of the trailing edge of the sheet by moving (47, 44) a shear cutting assembly (38, 39) transversely across the direction of movement of the copy sheet path of the copier upstream of the lead edge registration position at slightly less than the sheet width distance, and providing irregular width cutting of the sheet (non-cutting of the tab area). The latter may be provided by a tab interruption (38b) or offset of mating tab cutting shear wheels on the shear cutting assembly, and this may be variably repositioned (54, 50) by indexed rotation of the shear wheels to change the tab cutting position.

Abstract: A polyacrylamide type gel medium for electrophoresis is conveniently and safely prepared prior to use from a kit which comprises (1) a water-soluble copolymer of an acrylamide monomer and at least one comonomer copolymerizable therewith, which comonomer contains functional groups that permit crosslinking of said copolymer by a covalent but non-free radical initiated mechanism; and (2) a selected crosslinking agent in a package that separates it from the copolymer. Optionally, additional materials that may be usefully incorporated in the gel may be included in the kit, for example, a selected electrophoresis buffer and a complexing agent, such as SDS. The kit is used to prepare the gel by forming a solution of the copolymer in deionized water at the desired concentration of copolymer, adding a sufficient amount of any optional ingredients to provide the desired concentrations thereof, adding such concentration of the crosslinking agent as will provide a gelation time of between 5 minutes and 15 hours, and pouring the so prepared reaction mixture into a preselected mold or casting device or onto a support so as to form the resulting gel into the desired shape and size.

Abstract: An infrared spectral difference detector capable of detecting an excess or deficit of infrared radiation having a preselected wavelength and for automatically analyzing the spectral content of infrared radiation. The detector processes at least two channels of infrared radiation information in order to display spectral distributions or to detect spectral distributions which differ either from normal blackbody radiation or from a reference signal. The detector may be implemented in a portable, hand-held unit for providing instantaneous detection capability for the field of view of the detector. Alternatively, the detector principles may be employed to modify a standard forward-looking infrared (FLIR) thermal imager to obtain pictorial representations of the spatial distribution of sources and absorbers of infrared radiation within a preselected narrow band of infrared wavelengths.

Abstract: A snap action switch (20) comprises a contact (26) having a cut-out tongue (31) mounted on a post (37) with the tongue (31) bent to form a spring, the post being one terminal (23). The other end (35) of the element remote from the tongue end (32) initially contacts an exposed second (24) or third (25) terminal above or below the other end. 
     When the actuator or nose (44) from a resilient body acts against the surround adjacent the tongue end (32), force is exerted against the contact. As a result the contact snaps from the initial connection between the nose (44) and one of the second or third contacts (49 or 50) to the other. When the resilient body is relaxed to permit the nose (44) to resume its original position, the switch snaps back to resume connection between the post (37) the initial connection with the second or third terminal (24 or 25). 
     The disclosure includes an incipient form (69) of the snap action switch; and also a method of making the incipient form (69) and the switch (20).
