Abstract: A method for preparing hydroxamic acid polymers from primary amide polymers wherein polyvinyl monomers such as polyacrylamide are reacted with hydroxyl amine in aqueous solution at room tempera-ture.  The low reaction temperature is crucial to producing a high yield (70%) of polymer with hydroxamic acid groups and having a low carboxylic acid content (less than 15%, preferably less than 3%).  The polymers display high metal affinity over a broad pH range.     The polymers are particularly useful for biomedical applications due to the low carboxylic acid content and for the removal and purification of metals due to the high binding constants and rapid reaction rates.

Title: Decorrelation tolerant coherent radio altimeter
Inventor: BJORKE MERLIN D
IPC: G01S13/32
Filed: 1988-03-28
Granted: 1993-05-18
Abstract: ABSTRACT       A pulsed coherent radar altimeter is described which employs a narrow band receiver and utilizes a novel digital coherent pulse generator.  A coherent pulse radar transmits a pulse comprised of the sum of at least two phase related RF signals closely spaced in frequency.      The phase shift due to platform motion and return surface irregularity of the return signal is approximately the same for each carrier.  The receiver produces a signal representative of the difference of the two carriers which is substantially free of decorrelation effects, and which can be processed in a narrow band receiver to produce range information.

Abstract: A  re-inking  device  is  applied  to  a  cartridge  of  the  type comprising a container having a magazine for accommodating an inked ribbon of the closed loop type disposed in loosely arranged turns,  and a pair of toothed feed rollers for unidirectional feed of  the ribbon.   The re-inking device comprises an ink reservoir which  is  housed  in  a  closed  casing  fixed  removably  in  the interior of  the container,  and an ink metering means having an internal portion and an external portion.  The internal portion is inserted by  way of an  aperture  into the  interior of the casing and  is  held  in  contact  with  the  ink  reservoir;  the  external portion  is  in  contact  with  the rounded external  surface of  the teeth of an  inking roller.   The inking roller is always engaged with  a drive roller of  the pair of feed rollers.   A guide bush directs  the  inked  ribbon  towards the teeth of the inking roller; the ink passes from the metering means to the rounded surface of the  teeth.    The  teeth  in  turn  transfer  the  ink  to  the ribbon which is engaged with the feed rollers.  The metering means, the inking roller and the inked ribbon are of the same height, thus providing for uniform re-inking of  the  inked  ribbon  during the feed of the inked ribbon.

Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a fragrant air supplying method, supplying apparatus, and a building having a fragrant air suppling system for supplying fragrant air to rooms.  A fragrant-material supplier supplies fragrant material to a mist-generator to generate mist either by blowing air or by vibration produced by an ultrasonic-oscillator.  The mist is blown toward a surface portion formed at the end of a fragrant-air separator which separates evaporated fragrant air from mist.  The fragrant air is then introduced into holes formed in a fragrant-air discharger, in which the positions of holes are offset from the surface portion toward the downstream of the fragrant air.  The fragrant air is then blown into a distributing passage from the fragrant-air discharger to mix the fragrant air with air-conditioned air supplied by an air-supplier.  This produces fragrance-mixed air for distributing to a predetermined space or to rooms in order to influence the physical and mental states of the human body.
