Abstract: 1477063 Direction finder FRIED KRUPP GmbH 20 March 1975 [21 March 1974] 11725/75 Heading G1G A sum-and-difference type direction-finder having two pairs of omni-directional Piezo-electric hydrophones arranged in a cross formation with the hydrophone spacing small in relation to the wavelength of sound to be received is characterized in that the two hydrophones of a pair, i.e. those on one arm of the cross, are connected in series to form a closed circuit, the loop currents for the two circuits thus formed are added then integrated to form the sum signal, and the respective difference signals for the two arms of the cross are taken as the voltages across the terminals of a hydrophone of a respective closed circuit. The Fig. 2 embodiment closed circuits comprise hydrophone pairs 1, 3 and 2, 4 respectively, the loop currents being summed in a common current sensor 10 whose output is integrated at 13. The sum, Sl, and difference signals, DS1, DS2, are taken from the points shown and fed to a direction indicator. The closed circuit arrangement enables the direction-finder to be used with very low acoustic frequencies, < 30 Hz, at which the resistance of the Piezo-electric material of the hydrophones is small compared to the materials capacitative reactance, since frequency-dependent phase errors in the hydrophone outputs are avoided. The current sensor and integrator may be an operational amplifier with negative feedback via a capacitor, Fig. 3 (not shown), or respective current sensors for the closed circuits may be used instead of common sensor 10, Fig. 1 (not shown).

Abstract: 771,682. Buttering and slicing bread. KOMIEROWSKI, P. M. I. April 26, 1955 [April 26, 1954], No. 11928/54. Classes 28(1) and 28(2) A bread-buttering or like machine comprises a container or duct 13 for the butter or the like having a slot-like outlet 16 for the butter closed by a pair of meshing toothed rods 18, 19 mounted within the container or duct with their longitudinal axes parallel to the longitudinal axis of the aperture, means being provided to move the bread relatively to the aperture at right angles to its longitudinal axis and close to it. As shown, the butter in container 13 is pushed down by a weight 15 and a blade 20, attached to container 13, spreads the butter on the bread' as it passes. The bread-buttering machine is shown in Fig. 4 incorporated in a bread slicing machine. A loaf 33 rests on a platform 32 of a carriage 28 which is reciprocated on guide bars 27 by a crank arm 31 driven by a motor 24 so that a rotating blade 25 cuts a slice off the loaf at each reciprocation. The loaf is shifted endwise by the thickness of a slice, after each slice is cut, by a push plate 33 with an arm 42 sliding on a horizontal rod 36 on carriage 28. Arm 42 carries a pawl 37 spring urged to engage a rack bar 38 linked at one end, by an arm 40, to one end of a short vertical spindle 39 journalled in a bearing on the carriage 28. The other end of spindle 39 carries a.horizontal arm 43 carrying a roller 65 which engages a guide rod 66. During slicing and buttering, arms 40, 43 hold bar 38 against the action of spring 67, but towards the end of the return stroke of carriage 28 a roller 65 encounters an adjustable oblique portion 68 of guide 66 so as to turn spindle 39 and allow bar 38 to move lengthwise under the action of spring 67, pawl 37 riding idly over the teeth of bar 38. On the next feed stroke of carriage 28 the roller 65 runs back along portion 68 of guide 66 and bar 38 is drawn forward and drives pawl 37 to push loaf 33 forward one slice thickness. The buttering unit is driven by a rack bar 54 which moves with carriage 28 and meshes with a gear wheel 55 on the spindle of one of the pinions which feed the butter through the slot. The bar 54 is arranged to drive the pinions only when the end of loaf 33 is passing buttering slot 48. Butter is fed only during the stroke of the carriage taking the loaf to the knife blade since, on the return journey, the bar 54, which slides in guide member 56 and is mounted by a pin 57 working in a slot 58 in a bracket 59 fixed to the buttering unit, slides out of engagement with the gear wheel 55, Fig. 6. Handle 44 is provided to pull back plate 35 when a new loaf is inserted.

Abstract: 1358549 Corrugating E W VAN DIJK 14 March 1973 [14 March 1972] 12353/73 Heading B3E A series of undercut corrugations are formed in sheet metal by moving towards each other two clamps on the sheet, while a former moves upwardly between them, so that the sheet is folded around the former to form an undercut corrugation. In the figure, clamps 2a, 2b and 3a, 3b have moved together from stops 6b, 6d to abut stop 5a, while a former 4b has moved upwardly between them to meet a descending counter-die 4a, so as to form a corrugation to the shape of the former. Stops 7b, 7d are then moved to the position shown, and the clamps withdrawn against them, as shown, opening the corrugation enough to allow the former to be withdrawn downwardly. The clamps are then moved towards one another again to reshape the corrugation. Stops 7b, 7d are then withdrawn, and the clamps released and returned to stops 6b, 6d, clamp member 3a rising sufficiently to allow the formed corrugation to pass beneath it as the sheet 1 advances to the right. If the material is sufficiently springy that the former may be pulled out of the corrugation without deforming it, opening and re-closing of the corrugation may be omitted.

Abstract: 1429331 Synthesis gas; fuel oil PULLMAN Inc 15 March 1973 [7 Nov 1972] 12468/73 Heading C5E Synthesis gas is produced by (a) introducing a hydrocarbon feedstock into a catalytic cracking zone in the presence of cracking catalyst, e.g. zeolite under fluid cracking conditions to produce an effluent which is then fractionated to produce a cracked naphtha fraction, (b) hydrogenating this fraction with hydrogen to saturate olefins and aromatics at least partially and produce a more saturated cracked naphtha fraction, and (c) introducing this so treated fraction and steam to a catalytic steam reforming unit to produce an effluent containing synthesis gas. The effluent from (c) may be CH 4 -enriched by adding a CH 4  containing fraction or by hydrogasification, methanation or CO 2  removal. The hydrocarbon feedstock, e.g. crude oil, topped petroleum or a heavy hydrocarbon fraction may be distilled to produce a virgin naphtha fraction, a light gas oil fraction and a heavy bottoms fraction wherein the heavy bottoms fraction is fed to the catalytic cracking zone, the virgin naphtha is blended with the more saturated cracked naphtha fraction from (b) and the light gas oil fraction is blended with part of the heavy bottoms fraction to produce a fuel oil. The fluid cracking catalyst is regenerated in a regeneration zone, producing steam as by-product for the steam reforming stage. A H 2 -rich gas is obtained from fractionation of the catalytic cracking effluent and this is used in the hydrogenation step.
