Abstract: 1,093,430. Regulating I. C. engines. SULZER BROS. Ltd. Dec. 31, 1964 [Jan. 31, 1964], No.53011/64. Heading F1B. In a method of operating a four-stroke supercharged diesel engine in which the effective length of the compression stroke is less than the full length of the compression stroke and the effective length is not varied during engine operation, the charging air is cooled at a rate which decreases as the engine load decreases. Engine M has a charging air blower L driven by exhaust gas turbine T. A charging-air cooler K has a by-pass U containing throttle D controlled via a controller R and signal line S in dependence on an engine parameter which varies with the load e.g. speed, torque, fuel quantity or pressure, air charging pressure or air temperature after compression. Alternatively the coolant flow through the cooler may be by-passed or throttled.

Abstract: 1483808 Measuring alignment of vehicle wheels FINMEKANO ERIK SAMUELSSON AB 9 Dec 1974 [7 Dec 1973] 53075/74 Heading GIX The angular position of the axis of rotation of a vehicle wheel is determined in relation to the longitudinal axis 15 of the vehicle by locating an optical axis orthogonally to the geometrical extension of the axis of rotation and in a plane containing the longitudinal axis, and comparing the distances between the longitudinal axis 15 and one point on each of the two extensions of the optical axis in opposite directions from the geometrical extension. In one embodiment, figure 1, a sight instrument 4 is mounted on extension 1 so as to provide a sight line 5 parallel to the axis 15A. A measuring rod 2 is provided at each end of a chassis 10 each rod 2 having a scale 3 the scale distance from axis 15 being the same for both rods. By observing the position at which the sight line 5 impinges on each of the scales, the axle angle may be determined. In a second embodiment, Figure 2, a plane mirror 7 is mounted on and parallel to the extension 1, the distances between the longitudinal axis and one point on each of the two extensions being compared by defining a sight line 8 parallel with the longitudinal axis 15 and intersecting the mirror 7, and determining the distance between the sight line 8 and its reflection where they intersect a plane normal to the axis 15. The plane may be defined by a scale 9 built into a sight instrument 4 or may comprise a separate scale 3. The sight instrument 4 may be binoculars or radiation sources which emit light beams, for example laser beams, or other electromagnetic radiation. The extension 1 may be mounted in position to constitute the geometrical extension by a device comprising three arms on a plate. The arms may each support a support screw (21) Fig. 3 (not shown) which acts on the lateral plane of the rim and on two of the arms are provided an adjustable screw (22), the third arm carrying a screw (23) mounted on a locking lever 24. In a further embodiment Fig. 4 (not shown) each arm is provided with a holding magnet (27). The plate is centered by two arms (29) which are fastened with their free ends each on a wheel nut (30).

Abstract: 1,268,277. Piles. RAYMOND INTERNATIONAL Inc. 31 Oct., 1969 [27 Nov., 1968], No. 53497/69. Heading E1H. To form a concrete pile in situ co-axial shells 12, 14 are first driven into the ground by a vibrator 20 while secured thereto by clamps 22. When the desired depth has been reached the clamps 22 are released, turned horizontally (with the vibrator) through 90 into alignment with a pair of diametrally-opposed slots 26 in the shell 14 and brought into engagement with the shell 12 so that the latter can be withdrawn to remove the earth core 33, if necessary the vibrator being operated gently to minimize friction between the shells. Subsequently the core is dumped by operating the vibrator vigorously, the shell 12 is replaced within the shell 14, concrete is poured into the shell 12, and finally both of the shells are extracted simultaneously with the aid of the vibrator and clamps. Operation of the vibrator during the final step not only reduces friction but also consolidates the concrete. The step of replacing the shell 12 within shell 14 may be omitted, the concrete being poured into the latter.

[Also in Division G3] An ultrasonic generator is operated by passing a fluid under 0À5-6 p.s.i.g. through a throat 18, past entrances to resonant cavities 24a, 24b, to an outlet channel 30. Channel 30 is designed to minimize impedance. The output is taken either from open ends 26a, 26b of cavities 24a, 24b, or the output from one cavity may be reflected as at 28 to the open end of the other. Alternatively (Fig. 1, not shown), the fluid pressure is 0À5-3 p.s.i.g., cavities (20a, 20b) are closed, and the output is taken from an outlet channel (22), which has parallel sides. In both embodiments, the width of throat 18, the width of the cavity entraces, the depth and maximum width of the cavities are in the approximate ratios of 1 : 1À5 : 1 : 3. The lengths of the cavities and of the output channel are roughly equal to half the wavelength at the output frequency.

In the examples, a photo-polymerisable layer or a layer of polyvinyl cinnamate is coated on a support which may be polyester subbed with a vinylidine chloride copolymer or polypropylene. A receiving sheet is then laminated under heat and pressure to the photo-sensitive layer; speficied receiving sheets being unsubbed or subbed polyester, phosphoric acid or silicate treated aluminium or copper. The material is imagewise exposed and the receiving sheet with part of the unexposed areas stripped off by heating to 100C. This image may be developed by applying powdered pigment or transferred to a further receptor and developed. Alternatively, if a metal receptor is used, the image may be used as a printing plate or a printed circuit, preferably after a further heat treatment step. Further transfers of unexposed material from the support maybe made to fresh receiving sheets. Better images may be obtained by adding an ultraviolet absorber to the photo-sensitive layer.

Trans-1-chlorobutene-(2) and 3-chlorobutene- (1) are obtained by reacting hydrogen chloride with butadiene-(1,3) in equimolar amounts at 50‹ to 150‹ C. in the gas phase and in the presence of a catalyst which is a complex of (a) a chloride of a metal lower in the electrochemical series than calcium, and (b) an amine hydrochloride, the catalyst being supported on active carbon. The products may be separated by distillation during which they may be stabilized against dehydrochlorination by contact with a stream of nitrogen containing a small proportion of propylene oxide, unchanged butadiene optionally being recycled. The catalyst also has an isomerizing effect on the products so the process may be directed to the production of either one of them by recycling the other one together with fresh butadiene and hydrogen chloride to the reactor. The metal-chloride/amine hydrochloride compounds may be obtained by reacting metal chlorides with suitable amine hydrochlorides (e.g. those of heterocyclic bases, aniline, phenyl hydrazine or dimethylformamide) in the press ence of hydrogen chloride or hydrochloric acid.
