Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a novel polyaldimine, pre-paration process of the polyaldimine, moisture curable polyu-rethane composition containing the polyaldimine and use of the composition.  The polyaldimine of this invention is represented by the formula (I),                       (I) [wherein R1, R2 and R3 may be the same or different and are hal-ogen, hydrogen, alkoxy having 1 to 4 carbon atoms or alkyl having 1 to 5 carbon atoms; R4 is hydrogen or methyl; Y is -N=CH-C(R5)3 or -N=CH-C(CH3)2-CH2-O-CO-R6 (wherein R5 is an alkyl group having 1 to 4 carbon atoms, R6 is alkyl having 1 to 16 carbon atoms, anilino, benzylamino or alkylamino having 1 to 16 carbon atoms); ? is an integer of 1 or 2: m is an integer of 1 to 3; and n is an integer of 0 to 300].  The polyaldimine is prepared by con-densation of the corresponding aromatic polyamine and aldehyde.  A moisture curable polyurethane composition is prepared from the above polyaldimine and an organic polyisocyanate.  Sealing ma-terials, wall covering materials, water proof materials and floor-ing materials can be prepared by blending a thiotropic agent or a filler with the polyurethane composition.  These materials have very good storage stability and are rapidly cured by atmospheric moisture and cured polyurethane resin having excellent properties can be obtained.

Filed: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE           An automatic gain control (AGC) for a demodulator which received digitally modulated burst signals time-serially from a plurality of terminals.   The AGC has a series connection of a variable attenuator and a limiter that precedes a demodulator.  The variable attenuator is controlled such that when a burst signal is absent, the noise power level inputted to the limiter coincides with a predetermined reference value, whereby when burst signal is present,  the  limiter  controls  the  burst  signal  to  a predetermined level.   As a result,  when burst signals greatly  differ  in  level  from  one  another,  they  are controlled to the predetermined level in their preamble word portions.  This insures stable demodulation of data signals.

Title: Boat hook device
Inventor: REED ALLAN R
IPC: B63B21/54
Filed: 1990-12-10
Abstract: ABSTRACT OF THE DISCLOSURE   A boat hook which permits selectively releasable connection with respect to a conventional snap-hook of a standard mooring line. The boat hook is composed of a handle which terminates at a remote end in a snap-hook holder. The snap-hook holder is composed of two parts: 1) a seating member which is dimensioned so that the general vicinity of the eyelet area of a conventional snap-hook can seat snugly therein, and 2) a biasing member, which is hingably biased with respect to the seating member so as to selectively retain the snap-hook seated in the seating member. Once the snap-hook has been manipulated by the handle so as to be connected onto an eyelet of an object, such as the bow eyelet of a boat, a sharp pull on the handle will cause the snap-hook to be released from the handle of the boat hook.

Abstract: A hydraulic well tool is provided for running into a flow conduit of a well on a handling string, such as reeled tubing or jointed pipe, for generating and applying an axial force to an object in the well.  The tool is anchored in the flow conduit by an anchoring mechanism actuatable by fluid pressure in the handling string and it also includes a piston/cylinder arrangement that is actuatable by fluid pressure in the handling string for moving the object. The tool may be provided with means to permit increasing the fluid pressure for actuation of the anchoring mechanism and the piston/cylinder arrangement.  Such means including flow restrictors ball valves, velocity check valves and plugs.         The displacement of the object is achieved hydraulically while the well tool is anchored in the flow conduit and without axially stressing the handling strip.  The anchoring mechanism may have piston-type anchor members each formed with a sinusoidal seal ring recess at its inner end for increasing its stroke, and with retraction springs to avoid obstructing the longitudinal body bore.

Abstract: Dans une installation biologique les microorganismes dégradent la matière organique polluante durant un temps de séjour assez long et sur des grandes surfaces de terrain. Le traitement physico-chimique sépare la pollution ( même des composants non biodégradables ) mais produit des grandes quantités de boue et utilise des substances chimiques dispendieuses qui peuvent nuire à l'environnement. Les lits bactériens séparent et dégradent les matières polluantes organiques, mais posent des problèmes d'encombrement, de colmatage, d'odeurs et d'entretien. La présente invention consiste en une installation simple,rélativement peu encombrante et peu dispendieuse qui stimule la production de substances polymèriques extracellulaires par de microorganismes appropriés, et, ensuite, la séparation et la décantassions de ces polymères une fois charges en pollution. L'installation n'utilise pas des substances chimiques de flocculation, flottation ou sedimentation, les boues obtenues étant des produits absolument naturels, avec un volume beaucoup inférieur à celui des boues physico-chimiques. L'installation est de type "séparateur biologique" et ne dégrade que partiellement la pollution agglomérée. Le temps de rétention de l'eau à traiter est court (dizaines de minutes) ce qui permet le traitement de débits assez grands dans des installations de dimensions modestes.

Filed: 1991-07-22
Abstract: A core assembly for a pneumatic tire, which is fitted annularly to an outer peripheral surface of a well portion of a rim, and which rotates should the pneumatic tire collapse owing to a decline in its internal pressure, as an outer surface of the core assembly comes into contact with an inner peripheral surface of a crown portion of the pneumatic tire and an inner peripheral surface of the core assembly slides over the outer peripheral surface of the well portion of the rim.  The core assembly includes a sliding portion formed of a resin material having good sliding properties and high heat resistance, and a main body to which the sliding member is secured and which is formed of a material having a high rigidity and a low specific gravity.  Accordingly, since the surface of the core assembly contacting the rim is constituted by the sliding member, the core assembly is rotated smoothly when the internal pressure of the pneumatic tire declines, and the overall weight of the core assembly is reduced.

Abstract: Abstract The invention relates to a combustion process, e.g., for waste combustion units, in which fuel is burned with feeding of combustion air, which basically consists of ambient air enriched with oxygen.  It is proposed to feed combustion air with an increased oxygen portion relative to the ambient air only to those phases of the combustion process in which basically the entire amount of oxygen is consumed except for a random residual amount to be preset.  The combustion air with increased oxygen content is thus specifically introduced corresponding to the actual requirements of the combustion process.
