Abstract: Abstract A control device for an instrument (10) attached to a vehicle wheel hub for recording the distance covered by the vehicle comprises a counting mechanism with several number-carrying wheels (25), a stamping mechanism (29,30) for stamping card , a means (41) for advancing the number-carrying wheels of the counting mechanism in response to the distance covered, and a pendulum, the oscillation axis of which coincides with the vehicle wheel axle, and which by substantially standing still effects a relative movement in relation to the record-ing instrument. This movement is utilized for driving the means for advancing the number-carrying wheels of the count-ing mechanism via a gear unit (12). The means for advancing the number-carrying wheels of the counting mechanism comprise a feed hook (14), which is deformed permanently when number-carrying wheels of the counting mechanism are blocked, and thereby effects permanent closing of a first electric contact (14b - 34). A movable member (18) in the gear unit (12) is provided with at least one signal shoulder (49), which is capable upon movement transfer of the gear unit to altern-atingly open and close a second electric contact (33 - 34). Furthermore, members (34,35) are provided for scanning the condition of the electric contacts in order to render possible rapid observation, whether the recording instrument operates in the way intended.            Fig, 1 to be published.

Abstract: DISSOLUTION OF METALS                       ABSTRACT        Improved metal dissolution rates are obtained when using a solution containing sulfuric acid, hydrogen peroxide and certain primary diols.           The present invention relates to the dissolution of metals in an aqueous bath containing sulfuric acid and hydrogen peroxide, and in particular to a novel bath composition capable of effecting the dissolution at high rates.  In one specific aspect the invention is concerned with etching of copper in the production of printed circuit boards.                 BACKGROUND OF THE INVENTION           As is well known in the art, in the manufacture of printed electronic circuits a laminate of copper and etch resistant material, usually plastic, is used.  A common method of obtaining the circuits is to mask the desired pattern on the copper surface of the laminate with a protective resist material, which is imper-vious to the action of an etch solution.  In a subsequent etching step, the unprotected areas of the copper are etched away, while the masked areas remain intact and provide the desired circuiting supported by the plastic.  The resist material can be a plastic material, an ink or a solder.         In the last few years, the industry has more and more turned to hydrogen peroxide-sulfuric acid systems for etching the electronic circuit boards, due to the low cost of the etching solutions and to the relative ease with which copper values can be recovered from the spent etch solutions.

Abstract: ABSTRACT OF THE DISCLOSURE          A rotary fluid pump has a rotor with a sinusoidal, undulating, vane projecting  radially from a hub portion rotatable in a pump chamber having a suction chamber, dis-charge chamber and a transport zone extending circumferentially from the suction chamber to the discharge chamber.  The transport zone has a cylindrical inner periphery which is slidably engaged by the periphery of the rotor vane and opposite planar end walls slidably engaged by crests of the undulating vane.  Between the suction chamber and the discharge chamber there is a gate assembly with two sliders engaging opposite sides of the vane respectively and interconnected by a bow spring so that they move together.          The gate assembly, rotor and casing parts forming the pump chamber are all contained in a cylindrical outer housing, from which they are easily removed for cleaning, in-spection and replacement.  The sliders have round noses and the rotor vane is formed with varying thickness to provide contact of the sliders with all portions of opposite surfaces of the vane. This is achieved by con-touring the surfaces by a tool having the same radius as that of the slider noses.

Abstract: ABSTRACT OF THE DISCLOSURE        An  improved  hose end  sprayer  is provided  in which chemical  concentrate  from a  reservoir  circumscribing  a  tube secured to the end of the hose is gradually fed into a liquid stream passing through the tube.   A back pressure baffle is fitted within the tube between a pair of holes spaced in the tube  in  the  portion  thereof  circumscribed  by  the  reservoir walls.   A  first  of  the  holes  permits  gradually  release  of liquid  concentrate  within  the  reservoir when under  pressure into  the  tube.   This  hole  is  positioned  downstream  of  the baffle.   A partition within the  chamber  is  fitted  over  the tube, at least a portion thereof being movable under pressure from liquid within the tube passing through the second hole upstream of the baffle into the reservoir.  This action causes sufficient  pressure  on the  concentrate to cause  its gradual release through the first hole into the tube.  This relatively simple construction enables concentrate from the reservoir to be  passed  into  the  stream  of  liquid  while  the  partition minimizes  dilution  of  the  concentrate  in  the  reservoir  by liquid from the tube, a problem often found in prior are hose end sprayers of this general type.

Abstract: A B S T R A C T        A steam-generator control method is proposed for controlling the mass flows of an oxidant and a fuel which are supplied for combustion.  In order to control the flows at stoichiometric ratios with a required accuracy, the controlled variables are established by the measurements of the mass flows and their comparison with theoretically predetermined stoichiometric ratios.          Measurement errors are defined continuously through a combustion-gas analysis, conducted by means of a probe after the combustion.  The errors are used for the correction of the controlled variables.  The time constant of the correction is smaller than the time constant of dynamic changes of the errors.
