IPC: B65B35/28
Filed: 1969-01-23
Abstract: 1,257,344. Endless conveyers. HAUNIWERKE KORBER & CO. K.G. 23 Jan., 1969 [22 Feb., 1968], No. 3809/69. Heading B8A. Candy bars and like articles are fed by an endless conveyer belt 3 to an intermittently driven rotary carrier 30 of a wrapping machine and withdrawn therefrom by a similar endless belt 48. The belts 3, 48 each have a plurality of apertures 4, 49 and co-operate with vacuum chambers 55, 63 disposed adjacent the carrier. In operation the articles 5 are advanced continually by the conveyer 3 and are retained thereon by the vacuum chamber 55 with a sufficient force to allow those articles in advance thereof to be pushed on to a plate 33 and into the path of a pusher plate 34 of the rotary carrier 30. The entrance portion 53 of the plate has apertures 73 co-operating with an air pressurized box 74 to provide an air cushion for the articles. At the discharge point of the carrier 30 the conveyer 48 is received in a recess 31a of the plate 33, on a level with the plate, and any articles delivered to the conveyer are retained thereon by suction from the vacuum chamber 63 and conveyed clear of the wrapping machine. The vacuum chambers 55, 63 are coupled through control valve 57, 65 to a vacuum source, which valves are actuated by a cam wheel 67 driven in synchronism with the rotary carrier such that a vacuum is only applied to the chambers when the rotary carrier is in a position to receive or discharge an article. In an alternative embodiment, Fig. 3 (not shown), the rotary carrier (130) is continuously driven and has a mechanical discharge pusher. An air chamber (190) is arranged beneath the feed conveyer to provide a vacuum under normal operating conditions. If, however, the rotary carrier (130) should stop or become blocked a valve (182) controlling the air chamber (190) is switched to shut off the vacuum and provide pressurized air and hence an air cushion for the articles on the conveyer in order that the latter may pass there under without causing damage thereto. A device for sensing the build up of articles on the conveyer belts, Fig. 4 (not shown), comprises a chamber (7) arranged below the conveyer and in communication therewith through a slot (8). The chamber is coupled to a vacuum source and houses a bellow unit (13) whereby when articles build-up on the conveyer and cover the slot, the bellow react to a change of pressure in the chamber and actuate a micro-switch (18) whose output may be used for producing an optical or acoustic signal or for controlling or stopping the supplying machine or the supplied machine.

Abstract: 1289160 Catalytic hydrogenation; solvent extraction CITIES SERVICE RESEARCH & DEVELOPMENT CO 13 Nov 1969 [3 Dec 1968] 55681/69 Heading C5E A hydrocarbon feed 11, e.g. vacuum or atmospheric residual oil or a tar sand oil, has its content of material insoluble in tetrahydrofuran (THF) reduced by (a) extracting at least a portion of the feed at 13 with THF and/or (b) diluting the feed with a recycled heavy oil stream which has had its content of material insoluble in THF reduced by extraction with THF, before being hydrogenated. Hydrogenation is carried out at 26 at 700-900 F. and 1000- 3000 p.s.i.g. partial pressure of hydrogen in a fixed or ebullated bed of catalyst containing Co, Fe, Mo, Ni, W or a mixture of cobalt and molybdenum on an alumina or alumina-silica support. The hydrogenated effluent is fractionated at 35 provide naphtha, fuel oil and a bottoms fraction 38 which can be recycled to the hydrogenation reactor 26 or to the THF extraction. The THF extraction is carried out at 100-150 F. by contacting the feed with 1- 20 volumes of THF to form a slurry containing a solid precipitate of the THF insoluble material which mainly consists of materials of high molecular weight, e.g. above 500,000. The slurry is either filtered and the filtrate returned to the hydrocarbon feed extraction or the THF is recovered from the slurry by dissolving the solids in orthodichlorbenzene. The THF is recovered from the hydrocarbon feed oil by stripping at 22 and recycled to the extraction. During the hydrogenation at least 40 volume per cent of the feed boiling above 975 F. can be converted to materials boiling below 975 F.

Abstract: 1295575 Control of DC motors UNITED STATES ATOMIC ENERGY COMMISSION 19 April 1971 [17 Feb 1970] 20292/71 Heading H2V  Dynamic braking of a D.C. motor 15 automatically occurs immediately the source voltage 12 (which may be pulsed) falls below the back EMF of the motor. When terminal 13 is positive current flows through transistors 18 (NPN) and 19 (PNP) while transistors 23 (PNP) and 24 (NPN) are back biased and do not conduct. When the source voltage is removed the back EMF makes terminal 16 positive so current flows through transistors 23 and 24, the diode 26, and the damping resistor 27. The base-emitter junctions of transistors 23 and 24 are forward biased by resistors 29 and 30, and transistors 18 and 19 do not conduct. When the polarity  of the source is reversed transistors 23 and 24 conduct to drive the motor in the opposite direction, and when the source voltage is removed the back EMF makes terminal 17 positive and drives current through transistors 18 and 19, the diode 32 and damping resistor 33. If damping resistors 27 and 33 have different values, the rates of damping in the forward and reverse directions are different. Alternatively both resistors may be shorted out and one damping resistor 37 used for both directions. Diodes 26 and 32 block current from the source from leaking through resistors 27 and 33. In a second embodiment (Fig. 2) the circuit operates in a generally similar manner while utilizing only two transistors 45, 46 and two diodes 42, 52. If the motor is required to rotate in only one direction half the circuit may be omitted (Fig. 3, not shown).

Abstract: 1317558 Film fibrillation SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 26 May 1970 [26 June 1969] 32364/69 Heading B5B In a continuous process for the manufacture of synthetic fibres, from a molecularly orientable thermoplastic synthetic organic polymer in which a polymer film web is profiled using a profiling element, the resulting profiled web being split subsequently into individual fibres by longitudinal stretching of the profiled web, the ridged portion of the profiling element 4 is in the form of a band 5 bounded on each longitudinal edge by a ridge 6, and, immediately beyond said ridge, by a plain unridged portion 7 of width sufficient to prevent a groove formed in the film web of polymer from running into an edge thereof as a result of any lateral movement of said film web of polymer. The ridged portion of the profiling element may comprise ridges of unequal pitch 9, 10 such that the ultimate grooved web breaks down into a plurality of fibres of at least two substantially different deniers. As shown, the profiling element may be a driven profiling roller having circumferential parallel closely spaced ridges. Preferably, the width of the plain unridged portion 7 of the profiling element is such as to provide edge portions of the web of polymer which can be readily removed; ¢ to 2 inches width is suitable. The depth of the plain unridged portion may be equal to the depth of the portions between adjacent ridges of the profiling element; and beyond each plain unridged portion the surface of the profiling element may rise very slightly higher than the height of the ridges to form a shoulder 11. The ridged roller form suitably embodies a ridged portion which has ridges 9 of small pitch separated by a small number of ridges 10 of greater pitch; thus the small pitch ridges may have a pitch of 0À0125 inch and a depth of 0À0077 inch and the large pitch ridges may have a pitch of 0À020 inch and a depth of 0À0077 inch. The production of polypropylene fibres is exemplified.

Abstract: 1321241 Coin tester BRISTOL VENDING MACHINE Ltd 2 July 1970 [2 July 1969] 33434/69 Heading G4V A coin testing mechanism comprises a coin channel 8 (Fig. 2) having a V-shaped base 9, 12 and a coin-supporting guide rail 13, the arrangement being such that an inserted coin that is thinner and/or of smaller diameter than an acceptable coin, tilts laterally to fall beneath the guide rail 13 into a reject path. A thin coin drops further down into the V-shaped base 9, 12 to lose support from the guide rail 13. Fouling of the rail 13 by an unacceptable coin is prevonted by arranging for the plane of an acceptable coin to subtend a smaller angle with the base surface 12 than with the surface 9. The size of inserted coins is initially limited by a coin slot (not shown). In a first embodiment for accepting heavy, non-ferrous coins, a non-ferrous coin of acceptable diameter and thickness drops on to a support 14 (Fig. 1). Heavy coins are directed along an acceptance path (full line) by a pivoting of a weight tester 15. Ferrous coins are attracted by a bar magnet 16 and directed by the lower edge of a magnet support 10 into the reject path together with light coins (dotted lines). In a second embodiment for accepting heavy, ferrous coins, the magnet 16 is omitted and a magnet (18) (see Fig. 4, not reproduced) arranged adjacent the underside of the weight tester 15 to attract ferrous, heavy coins into the acceptance path; non-ferrous, heavy coins are deflected into the reject path by a projection (19). In a further embodiment (Figs. 5, 6, not reproduced) heavy coins pivot the weight tester 15 and are deflected into the reject path, while light coins pass into the acceptance path without pivoting tester 15.
