Abstract: ABSTRACT OF THE DISCLOSURE          A method of producing 6-.beta.-amidinopenicillanic acid derivatives of the general formula   where R1 and R2 are identical or different aliphatic hydrocarbons, R1 and R2 together with the nitrogen atom being capable of form-ing a heterocyclic system; R3 = H, alkyl, or aralkyl; the method residing in that esters of 6-aminopenicillanic acid of the general formula   where R3 is alkyl or aralkyl, are subjected to condensation with secondary amines of the formula   where R1 and R2 are identical or different, selected from the group consisting of aliphatic hydrocarbons with a non-branched chain, R1 and R2 to-gether with the nitrogen atom being capable of forming a hetero-cyclic system, said condensation being performed in the presence of orthoformates or orthothioformates, in an organic solvent at a temperature from -5°C to +30°C with subsequent isolation of the desired product.  The proposed method allows the production of said derivates of 6-.beta.-amidinopenicillanic acid in one stage, thus simplifying the technology as compared with the prior art methods.

Abstract: ABSTRACT OF THE DISCLOSURE     A mounting device for a compression spring includes a contact bridge carrier having first and second cavities which are interconnected by a breakthrough opening and a contact bridge.  A pull bracket, including a main portion which seats in one cavity of the carrier and a pair of arms extending into the second cavity through the breakthrough, retains the compression spring in the second cavity.  The pull bracket is supported on the contact bridge.  The arms positioned within the coils extend the length of the spring and just beyond where they are bent back in a direction parallel to their longitudinal axis.  A retainer washer is provided which has suitably dimensioned cutouts facilitating placement of the washer over the bent arms which then lock it in position to thereby retain the spring. The arms pass through the cutouts and are bent back around a corresponding crosspiece of the washer.  The mounting device is for use in an electric switching apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE      The disclosure relates to a label on a closured bottle, including a pilfer-proof feature.  The neck label comprises a secondary closure in the form of a sleeve of a shrinkable oriented thermoplastic material shrunken snugly over the bottle and its closure skirt. The label stock is preprinted in a web and rolled as a supply, the roll width representing the label height.  The label stock is (1) scored a partial depth of its thickness extending lengthwise along a line that is at a predetermined height in the final label and (2) pleated transversely at spaced intervals therealong.  The pleats are spaced so that a predetermined number thereof appear in each label blank cut from the stock.  Label blanks are cut to length, wound to an annular sleeve shape so that the trailing end of the blank overlaps the leading end and the overlapped ends united at an axial seam.  The sleeves are placed over the neck and closure skirt of a closured bottle such that the score line of weakening in the material is adjacent the lower edge of the closure skirt.  Heat is applied to shrink the label into snug surface engagement with the underlying surfaces.          The pleats, especially on smaller sizes of ware, avoid wrinkles in the shrunken label and enhance a smooth appearance thereof.          Preferably, the pleating in the label comprises at least a pair of pleats disposed on opposite sides and near the axial seam.     -i-

Abstract: ABSTRACT         An apparatus in the form of a sound-viewer-editor or sound projector and a method are provided for facilitating the editing of a motion picture film bearing a longitudin-ally extending principal stripe on which a sound track is magnetically recorded, such sound track being longitudin-ally offset in a conventional manner relative to the scene images recorded on frames of the film which also bears a second or so-called balance stripe of magnetic material. The apparatus comprises a viewing station such as a pro-jector aperture and first and second electro-magnetic heads for recording on and reproducing sound information from the principal stripe and the balance stripe respectively.  Such heads are interconnected through an amplifier and can be used first to reproduce the sound track from the principal stripe and record it on the balance stripe so that it is then in transverse synchronized alignment with the image-carrying frames.  After editing of the film, the apparatus can be used to erase the principal sound stripe and to re-produce the edited sound track from the balance stripe of the edited film and to record that edited sound track and additional sound on the principal stripe so that all sound is correctly longitudinally offset.  The apparatus also comprises a sound-reproducing head offset with respect to the viewing station (e.g. projection aperture) so as to allow simultaneous viewing (e.g. projection) at that stat-ion of the same images and synchronized reproduction of the related sound information as recorded on the principal stripe of the film for immediately audible projection.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention relates to a process for preparing active noble-metal catalysts on a carbon carrier. In particular, the process comprises adsorbing a soluble salt of the catalytically active metal onto the carbon in an aqueous medium; hydrolyzing said salt to the oxide or hydroxide, by employing a basic reagent; and reducing said oxide or hydroxide to the metal.  The porous carbon contains macro-pores of radius above 103 A, intermediate pores of radius between 20 and 103 A and micropores of radius not greater than 20 A, and the ratio between the pore volumes of the macro pores plus the intermediate pores and the total pore volume is between 0.6 and 1.0; and the hydrolysis of the noble metal salt and the reduction of the oxide or hydroxide formed thereby are carried out in a single processing step using liquid hydrolyzing and reducing agents.  The inventive process is relatively simple and avoids the formation of coarse metal crystallites.

Abstract: ABSTRACT    A grain storage bin has a floor with a central discharge opening, an elongated sweep auger extending radially from the discharge opening toward the wall of the bin, and an elongated shield extending alongside the auger.  The sweep auger and shield travel as a unit around the interior of the bin to channel grain toward the discharge opening as the auger is being rotated about its axis.  An elongated torque arm attached along-side the shield provides torsional reinforcing for the shield and longitudinal reinforcing for preventing the auger and shield from sagging mid-span.

Abstract: FLUID PRESSURE BRAKING SYSTEM    ABSTRACT OF THE DISCLOSURE A fluid pressure braking system for a vehicle having brake actu-ators which may be mechanically held in the brake-applied position when the vehicle is parked and which may be actuated from either service or emer-gency actuating systems, is provided with a fluid communication limiting valve which limits fluid communication through the service actuating system to the brake actuators when the actuators have been actuated by the emer-gency system, thereby providing an "anti-compounding" capability so that the brake actuators cannot be actuated by the combined full capacities of both actuating systems.  The system further includes a standby valve which is responsive to a normal brake application to communicate fluid pressure to the actuators through the emergency system when the failure of the primary fluid pressure system prevents communication to the actuators through the service system.
