Abstract: ABSTRACT         It has now been found that certain phos-phonate derivatives of bis(aminoalkyl)piperazines are good threshold agents to prevent metal ion pre-cipitation in aqueous solutions.  They also func-tion as sequestering and/or chelating agents as do those which do not contain the phosphonate group.          These compounds which have at least one of the amine hydrogens phosphonomethylated are employed as cement set retarding additives.

Abstract: ABSTRACT An apparatus for predictively coding and decoding is disclosed.  On the transmitting side, a motion vector contained in an input video signal is detected for each of a number of blocks, each of which consists of a plurality of picture elements and which spans over a plurality of scanning lines as a unit.  The motion vector is time-sequentially converted to match the time sequence of the input video signal.  A prediction error signal is obtained in response to the input video signal and the converted motion vector.  The prediction error signal is time-sequentially converted to have a higher correlation and the converted prediction error signal is coded by variable length coding inclusive of run-length coding and is transmitted.  On the re-ceiving side, the converted prediction error signal is decoded.  The converted prediction error signal is rearranged into the time sequence of the input video signal.  A video signal is predictively decoded in response to the re-arranged prediction error signal and a motion vector which is transmitted from the transmitting side.  The apparatus of the invention is capable of efficiently coding a video signal by using spatial correlations of not only a prediction error signal but also a motion detector.

Abstract: ABSTRACT OF THE DISCLOSURE        A gumming solution is disclosed for use in the burning-in of irradiated and developed offset-printing plates.   The gumming solution contains  (a) water,  (b) at least one hydrophilic polymer, and (c) at least one component derived from an organic acid.  Component (b) comprises, for example, N-polyvinyl-pyrrolidone-(2) or polyacrylic acid, and component (c) comprises a water-soluble  organic  carboxylic  acid,  sulfonic  acid,  or phosphonic acid which has at least two acid functions and which is selected from the group consisting of ben-zene carboxylic acids, benzene sulfonic acids, benzene phosphonic acids,  and alkane phosphonic acids, or one of  the salts  thereof  (for  example,  disodium-benzene-1,3-disulfonate, mellitic acid, or methane-diphosphonic acid.)   A process  for  the production of an offset-printing plate, using the aforesaid gumming solution in the burning-in of the plate,  is also disclosed.  With application of this gumming solution,  washing of the printing plate prior to printing is rendered unneces-sary, since the printing plate runs clean very rapidly during the printing process.

Abstract: ABSTRACT          TITLE:  A METHOD AND PLANT FOR COOLING GASES AND                  REMOVING DUST FROM THEM"            The invention relates to a method and a plant for cooling gases and removing dust from them.  In a first step after saturation with water vapour, the gas is brought to accelerate, additional water being simultaneously added to the dust particles in the gas, whereupon the gas flow thus loaded is brought to pass over the surface of the water in a first sedimentation container (1) so that the majority of the dust content is released to the sump in the sedimentation container (1).  The gas flow is thereafter subjected to final cleaning and cooling in a second step, through direct contact with water, whereupon the water utilized in this manner, possibly via a second sedimentation container (2), is wholly or partially returned to the first step.

Abstract: TRANSPARENT IRON OXIDE PIGMENTS                   Abstract of the Disclosure The present invention relates to a process for preparing transparent iron oxide pigments comprising reacting an iron compound, an ammonia releasing compound and water in a non-aqueous solvent in which both the iron compound and the ammonia releasing compound have appreciable solubility.  The reaction is performed by refluxing this composition.  Where a red pigment is desired, a high boiling alcohol may be employed whereby the refluxing is carried out above 200°C which thus converts the pigment to a red iron oxide pigment during the reflex step.  In order to get a metallic finish, aluminum flake pigment may be added to a mixture of the iron compound and solvent prior to addition of the ammonia-releasing salt.

Abstract: ABSTRACT OF THE DISCLOSURE     An  AM  stereo  demodulator   with   which   the transition from the stereo receiving mode to the monaural receiving mode upon a reduction in the field strength of the received signal is made gradual so as to eliminate an abrupt  change  in  the  sound  quality.     For  stereo demodulation,  a pair of  reference  signals are generated which are .pi./2 different in phase for stereo reception.  As the field strength of the received signal approaches the level where a phase-locked loop in the demodulator would become unlocked from the carrier of the received signal, the phase difference between the two reference signals is gradually reduced to .pi./4.

Abstract: Abstract of the Invention The cambered truss headed is embodied in a shoring apparatus for pouring substantially horizontal concrete building sections.  The truss header extends between and is supported on end runners which may be carried on floor-supported legs or on hangers mounted on upright building sections.  A truss header may consist of a truss span having a top chord member, a bottom chord member, and a plurality of like brace members interconnecting the chord members.  The brace members form an open web pattern wherein adjacent brace members are reversely inclined with the plurality of apices being connected to the top chord members a spaced apart distance greater than the spaced apart distance between the apices of the bottom chord member. The truss header is thus provided with a camber which tends to assume a horizontal position in response to a load placed on the truss header by the horizontal concrete building section.  By arranging a pair of truss spans side-by-side for relative longitudinal movement, the truss header may be adjustable in increments equal to the spaced apart distance between the connected apices of the brace members to accommodate spans of different widths.

Abstract: ABSTRACT OF THE DISCLOSURE        A pneumatic tire having a decorative ap-plique on the sidewall thereof.  The applique is protected from damage when the sidewall is curbed by the provision of a rib concentric with the ap-plique and interposed upon the sidewall between the applique and the tire tread.  A decoupling groove interconnects the applique and the rib and allows the portion of the sidewall maintaining the appli-que to decouple from the remainder of the sidewall, deflecting inwardly when the sidewall makes con-tacting engagement with a vertical surface such as a curb.  The deflection of the applique prevents contact with the curb and allows the rib to draw inwardly and over the outer edge of the applique, further protecting it from scuffing action.
