Abstract: Abstract of the disclosure: 3-Chloro-3-methyl-butane-1,4-dial-bis-acetals and 3-methyl-but-2-ene-1,4-dial-bis-acetals are obtained by reacting a six-membered cyclic acetal of 3-methyl-but-3-en-1-al with an alkyl nitrite in the presence of methanol and hydrogen chloride and, if desired, eliminating HCl in the conventional manner.        The butan-dial-bis-acetals and butenedial-bis-acetals are valuable intermediates through which the trans-3-methyl-but-2-ene-1,4-dial-1-ecetals, which are sought-after products for terpene syntheses, can be ob-tained in an industrially particularly advantageous manner.

Abstract: HYDRAULIC CLUTCH            Abstract of the Disclosure An hydraulic clutch comprises coaxial input and out-put shafts with driving and driven discs respectively mounted on the shafts.  The mounting of the driven discs on the out-put shaft includes a one piece member having a cup with an annular wall that surrounds the input shaft and the driving discs.  The one piece member also includes the output shaft.          An hydraulic piston is used to engage the clutch discs; and pins, around which return springs are mounted, limit the throw of the piston.  The arrangement tends to minimize tur-bulence, heat build-up, and power losses when the clutch is in the disengaged condition.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved technique for correcting errors in track, for example errors in alignment and cross-level.  A record of the actual geometric condition of a section of track is obtained by running a recording car operating at a predetermined speed and axle loading over the track.  A record which may be on magnetic tape is thus obtained for one or more parameters such as alignment.  In some cases this record may be used directly to derive electrical error signals which control a track moving device which moves the track in a direction to remove the error.  Where the parameter of interest is alignment and the section of track is curved, a desired geometric condition has to be obtained for comparison with the actual geometric condition to derive the electrical error signals.  One way of obtaining the desired geometric condition is to process the record to achieve a running average taking over ten or so consecutive sample points.

Abstract: Abstract A pea harvester is disclosed comprising a mobile chassis, a forwardly-extending pivotal frame structure, a rotary, tined, picking reel for gather-ing standing crop and at least one ground-engaging roller mounted on the forward end of the frame structure.  The roller serves to locate the picking reel so that the foremost tines are slightly above the surface of the ground. The frame structure is suspended from the mobile chassis in such a way as to establish a selected minimum ground pressure by the roller and thus enable the picking reel to maintain its position above the ground surface when travers-ing ground irregularities.

Abstract: ABSTRACT            The invention relates to a device for indicating air pressure change in vehicle tires. According to the invention, a trans-ducer is mounted fixed in the area of the hub of the wheel in question, which transducer continuously is affected by the changes in the dynamic behaviour of the tire which occur at driving owing to dropping air pressure. The output signal from the transducer is processed in an electronic unit for forming a secondary signal, which is an expression for the vertical acceleration component in the output signal. When the secondary signal deviates by an amount critical for the driving safety from a nominal value, warning is released.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for coating with a desired substance a succession of beverage bottles traveling along an arcuate guideway.  A star wheel assembly, rotatable about an axis at which the arcuate guideway is center-ed, feeds the successive bottles along the guideway, further coacting with the opposed guideway-defining surface to cause rotation of each bottle about its own axis.  Coaxially mounted on the star wheel assembly, either for simultaneous rotation therewith or for in dependent rotation, one or more annular rows of discrete coating bodies or one or more coating rolls apply the coating substance to the successive bottles, creating one or more band-shaped coatings around each bottle.          In one embodiment the star wheel assembly is replaced by a feed roll assembly comprising a pair of annular rows of independently rotatable feed rolls.

Abstract: ABSTRACT OF THE INVENTION      A measurement system detects a downhole drilling vari-able in relation to the rotational orientation of a drill string during drilling.  The system includes a downhole reference signal generator and a downhole variable signal generator.  The reference signal generator is coupled down-hole to the drill string for generating a downhole reference (DR) signal indicative of the angular relationship between the drill string and a directional reference, such as gravity or the earth's magnetic field.  The downhole variable signal generator detects downhole parameters and generates a down-hole variable (DV) signal representative of a downhole param-eter of interest during drilling.  The DV signal and the DR signals are thereupon processed, either downhole or uphole depending in part on the telemetry system employed.  The system is especially adapted for indicating the resultant lateral force applied to the drill string at the drill bit during drilling which is useful in projecting the probable drilling direction.
