Abstract: Abstract In order to create a service girder intended for use in the field of application of the conventional squared timbers and usable for such tasks, having dimensions in the range of approximately 10 to 20 cm in height, which is more econ-omical in use, after consideration of all the important practical aspects, than the formerly used squared timbers, a service girder of wood, which is connected with an upper flange and a lower flange and a flat solid web linking these two flanges which is linked to the flanges by a plu-rality of tongues engaging in said flanges and bonded over the entire length of said girder, wherein the web consists of plywood or of a plate of three wooden layers bonded to-gether and wherein the wood fibers of the outer layers run perpendicularly to the fibers of the center layer, and the flanges are in each case composed of several wooden layers, of which the wood fibers extend substantially in the longi-tudinal direction of the girder, is further developed in such a way that each flange (1, 2) consists of at least three wooden layers (5, 6, 7) and the wood fibers (F5, F6, F7) of each adjacent ?ir of wooden layers are mutually inclined at an angle of about 10° to 15°.

Abstract: Abstract of the Disclosure The subject invention relates to a process for preparing ferriferrocyanide pigments.  The process comprises (1)  forming a reaction mixture containing a ferrous salt and an alkali metal ferrocyanide;        (2)  adding an alkaline compound to said reaction mixture in an amount sufficient to raise the pH to at least 9;        (3)  oxidizing the basic solution by aeration;        (4)  heating the solution to a temperature of from 10°C to 90°C and (5)  recovering the pigment.         The advantage of the process is that no signifi-cant amount of Berlin White intermediate is formed.          Consequently, it is unnecessary to use sulfuric acid to dissolve the Berlin White before oxidation.  Moreover, oxidation is achieved by aeration.  This is cost effective and reduces the stress to the environment.  The resulting pigments are useful in coloring printing ink and carbon paper.

Abstract: GALVO POSITION SENSOR FOR IMPROVED TRACK  SELECTION IN OPTICAL DATA DISK SYSTEM          By Paul M. Trethway ABSTRACT OF THE DISCLOSURE         Disclosed is a radiant energy optoelectronic position monitor system which detects the angular position of a "galvanometer mirror" (beam scanner) used in an optical disk memory arrangement.         Using a single infra-red monitor beam, angular motion is converted to linear displacement of an image on a detector cell so as to produce a corresponding electrical signal.  This signal is presented to a processing circuit with an analog divider to normalize output scale factor.  The result is a high gain electrical circuit for recovering output signals in an environment with strong magnetic interference.         Such a position sensor is described as especially apt for use in a "three beam" laser optical system comprising a writing beam and two reading beams all incident on the same track of a rotating disk optical recording medium.  One of these reading beams is incident on the track ahead of the writing beam so as to serve as a "read-before-write" beam, while the other reading beam is incident on the track behind the recording beam so as to serve as a "read-after-write" beam.

Abstract: ABSTRACT        The cutter connector has in its contact portion (1) two contact blades (2,3) with cutting edges, with which the insulation of the electrical conductor that is pressed between them is cut through to provide an electrical contact.  A U-shaped part (4) is mounted in such a manner as to be rotatable on the contact blade (2) so as to constitute an operating component; according to the rotated position of the contact blade this extends more or less, and it has two openings (5) through which the insulated conductor that is to be pushed in can be inserted.  The operating component itself, as well as its operating movement, thus require very little space.  One of the contact blades is itself used for the rotatable installation of the operating component.

Abstract: ABSTRACT OF THE DISCLOSURE       A piston for a reciprocating internal combustion engine includes at least one pressure ring installed in an outer surface of the piston main body adjacent to the piston head.          The pressure ring has a double-angle butt end construction comprising an outer circumferential surface slidably contacting the inner circumferential wall of the cylinder, a radially extending first butt flat end face, and a side wall facing the combustion chamber side, namely the high-pressure side, of the engine piston chamber.  Only a corner portion formed on the combustion chamber side of the pressure ring by the outer circumferential surface, flat end face and side wall is partial-ly cut away to form a notch which is contiguous to the outer circumferential surface, end face and side wall.  The pressure ring further includes a radially extending second butt flat end face opposing the first flat end face, and a rib projecting circumferentially from the second flat end face only at a po-sition corresponding to the notch, the rib having a shape which is complementary to that of the notch for being gas-tightly received by the notch when the pressure ring is installed in an outer circumferential groove of the piston main body.

Abstract: ABSTRACT OF THE INVENTION     A mixture containing oleophilic surfaced mineral particles and oleophobic gangue particles in an aqueous phase is separated by means of an apertured oleophilic endless sieve supported in a separating zone by a revolving cylindrical cage having apertured sidewalls and supported in a recovery zone by a support roller, each section of sieve surface alternately revolves through the separation zone and recovery zone.  The aqueous mixture is introduced as a slurry into the rotating cage in the separation zone.  The endless sieve partly covers the outside surface of the cylindrical cage sidewall.  An oleophilic adhesive is placed on the sieve as a coating or added to the aqueous slurry in the cage or both.  The adhesive attracts the oleophilic mineral particles.  The mixture tumbles inside of the cage and thereby is brought up to sieve speed and passes through the cage sidewall apertures to the sieve surface.  Aqueous phase of the mixture passes through the sieve apertures into a bath from where it is removed.  The oleophilic mineral particles of the mixture adhere to the oleophilic adhesive and are captured by the sieve upon contact and conveyed out of the separation zone.  Some residual aqueous phase is removed from the sieve after which it passes into the recovery zone where the mineral particles and some adhesive are removed from the sieve as a mixture.     In the recovery zone, mineral particles and adhesive mixture are removed from the sieve by squeezing the mixture on the sieve between two rollers.  At least one of these rollers is oleophilic and pulls mixture out of the sieve apertures which mixture coats the roller surfaces and revolves back to the nip between the rollers and is squeezed off.  This may be done with the sieve as it enters the recovery zone without heating it or the sieve and the mixture on the sieve may be heated with a hot roller to make squeezing off of the mixture easier.  Alternately, the mineral particles and adhesive mixture on the sieve may be heated in the recovery zone and, because of its apertured surface, be blown off, shaken off or thrown off the sieve under the in fluence of an applied force.

Abstract: "RECOVERY OF PRECIOUS METALS FROM           MATERIALS CONTAINING SAME"             Abstract of the Disclosure The recovery of precious metals from materials containing same is effected by leaching the precious metal in an acidic aqueous medium contain-ing chloride ions and a strong oxidizing agent to form a soluble chloride complex of the precious metal and thereafter separating the metal from the complex thus formed.  According to the invention, the chloride ions are derived at least in part from a non-acidic chloride-containing leaching agent which is non-volatile and soluble in the acidic aqueous medium without crystallizing under the leaching conditions.  The invention is particularly useful for recovering platinum and palladium from automobile catalytic converters.
