Title: Improvements in and relating to speed changing arrangements for three-phase shunt wound electric motors
IPC: B44C1/17
Filed: 1935-10-11
Abstract: 453,311. Alternating-current commutator machines. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Oct. 11, 1935, No. 28145. Convention date, Nov. 14, 1934. [Class 35] In a three-phase shunt motor wherein the stator winding may be connected to either of two sets of brushes at will to give sudden speed changes within wide limits, a device is provided for automatically coupling the auxiliary brushes to the main set so that they may be shifted when the main brushes or brush-holders are shifted. As shown in Fig. 2, the brushes are coupled so that when main brush 1 is moved by means not shown, the auxiliary brush 7 also moves until the end 32 of the lever 28 meets a pin 16 which can be placed in the path of the brush in any position, being movable by a rack and pinion. The pin 16 causes the lever end to rise sufficiently to free the pin 38 projecting from the main brush and as brush 1 moves away from the other, its second pin 39 causes bellcrank lever 35 to swing round and engage the pin 16 as indicated in Fig. 3. Brush 7 will remain in this position until the main brush is returned towards it and releases it from the pin 16.

Abstract: 667,985. Billet - piercing. AKT. - GES. OEDERLIN & CIE. Nov. 8, 1949 [Nov. 23, 1948], No. 28631/49. Class 83 (iv). For making shell-like hollow bodies a hot ingot 10 previously cut from a centrifugally-cast rod, is pressed into a bore 11 of a matrix 3, said bore 11 having a smaller diameter than the diameter of the ingot so that the latter is circumferentially condensed before the hollow pressing operation. As shown, the ingot 10 is pressed into the matrix bore 11 by a ram 13, the upper part 5 of which is enlarged and arranged to enter an enlarged upper guide portion 4 of matrix 3 when the ram 13 commences the hollow pressing operation. The ingot 10 is initially centred in the bore part 4 by three adjustable spring-pressed holders 6 which extend through radial bores in the matrix wall and are arranged for outward displacement when the ram part 5 engages therewith. To guide the ingot into the lower, smaller diameter, bore part, a conical or hyperbolical lead portion 12 is provided, the upper diameter of the lead portion being greater than the ingot diameter. It is stated that initial radial compression of the ingot, such as effected above, reduces the possibility of lateral displacement of the ram 13 during the final hollow pressing operation.

Title: Improvements in and relating to electric motor starting apparatus
IPC: H02P1/54
Filed: 1930-09-25
Abstract: 364,563. Control of several motors ; electromagnetic switches. BROOKHIRST SWITCHGEAR, Ltd., Northgate Works, Chester, and LANE, W. A., 20, Hampton Road, Buddicom Park, Cheshire. Sept. 25, 1930, No. 28680. [Classes 38 (iii) and 38 (v).] In a control system similar to that described in Specification 324,360, [Class 38 (iii), Electric motor control systems &c.], wherein any motor of a group M<1>, M<2> can be started by a common starting means R, a two-way auxiliary switch Z<1> is associated with each starting contactor S<1>. After the contactor coil S is energized by closure of the button A<1>, this switch Z<1> not only completes a maintaining circuit for the coil but isolates the button A<1>, so that should another button A<2> be closed whilst button A<1> is still closed, a false circuit for the associated contactors cannot be obtained over the button A<1>. This action prevents inadvertent starting of a second motor whilst one is being started. Two two-way auxiliary switches Z<2>, Z<3> may also be associated with the running contactor P<1> in place of the two single way switches p<1>, p<2> disclosed in the prior Specification. The association of a contactor with its twoway auxiliary switch is shown in Fig. 6. The armature P is pivoted on a pin 5 and has its movement limited by a pin 8 engaging an enlarged hole. As the contactor closes it operates a lever 18 through a pin and fork connection 20, and the lever 18 engages a pivoted arm 13 causing closure of contacts 2x, 15 and thereafter opening of contacts 1x, 15<1>.
Patent GB-1185788-A (GB)
Title: Improvements in or relating to Sheet Inspecting and Segregating Apparatus
IPC: B65H43/04
Filed: 1968-06-17
Abstract: 1,185,788. Delivering sheets. COLUMBIA CONTROLS RESEARCH CORP. 17 June, 1968 [20 June, 1967], No. 28706/68. Heading B8R. [Also in Division G1] In apparatus comprising an inspection station for sensing defects in a continuously moving web, a cutting station for cutting the web into sheets, and sorting means to separate sheets having defects from those without, means are provided for varying the length of sheets to be cut without changing the length of travel of the web between the inspection and cutting stations and still retaining information as to which sheet lengths contain defects and which do not. The inspection, cutting and sorting apparatus are substantially the same as those of Patent 1,115,982. After photo-electric sensing of defects by apparatus 15, and cutting of the web by a knife 20 carried by a rotating roller, the sheets are diverted, if necessary, by finger 27, into an appropriate container 26 for defective sheets, the reject signal obtained from apparatus 15 being delayed by passage through a shift register so that the finger 27 operates on the correct sheet. A switch 29 generates signals to cause energization of the solenoid (50) causing operation of finger 27 and switch 28.generates signals causing advance of information through the shift register. When it is desired to change the length of sheets being cut, the speed of the shaft 21 is changed by adjustment of drive means 22. This disturbs the timing sequence between inspection and cutting and so an adjustment to switch 28 is made. To do this, switch (52), Fig. 3 (not shown), is closed to connect the output of switch 28 with a solenoid 30 associated with a marker 31 at the inspection station. The switch 28 produces an output once per cycle of revolution of shaft 21, at a particular angle of orientation of the shaft, and will produce signals which are time displaced in relation to the cutting operations. A particular arrangement for setting this angle and thus the timing between each pulse from switch 28 and each cutting operation, is detailed in Fig. 2 (not shown) and comprises an actuator rotated by shaft 21a around a proximity switch. The marker 31 is thereby caused to mark the web once per sheet to be cut. When observed at the cutting station, the cutting may not be in register with the mark and thus the setting of switch 28 is adjusted to obtain register. The inspection operation has now been sequenced correctly with the cutting operation. The switch (52) is then opened and the switch 28 continues to cause advance of information through the shift register but in the correct time relationship with respect to cutting operations. The switch 28 may be a snap-action switch or a photo-electric arrangement. The marker can produce ink spots, notches, slits &c., the latter produced for example by spark discharge.

Abstract: <PICT:0711816/III/1> <PICT:0711816/III/2> <PICT:0711816/III/3> In the preparation of furnace carbon black wherein a hydrocarbon such as gas oil, is injected as vapour or sprayed as liquid, preferably axially, into a furnace chamber, and is thermally decomposed by hot gases, the hot gases are produced by an oil burner which comprises a cylindrical body, an oil spray injector to discharge oil axially into the body, an injector disposed to discharge air or oxygen-containing gas into the body tangential to the body inner wall, and an outlet from the body communicating with the chamber.  In Fig. 8 the axial stream of hydrocarbon forms a central column 101 in cylindrical furnace 59. Air is injected tangentially into burner body 67 and rotates as shown by arrow 103, while oil spray 63 rotates as shown by arrows, and the p  resulting column of hot gases enters the furnace with its axis tangent to the surface of axial column 101 and rotating in the direction shown by arrow 104, so that the portion of gases contacting the axial column is moving in the opposite direction thereto, with consequent improved mixing.  Depending on the amount of turbulence desired in the furnace, the direction of air and oil spray rotation may be reversed to cause the contacting gases to move in the same direction as the axial stream or the direction of oil spray and air rotation may be opposed and more than one burner may be provided with the direction of oil spray and air rotation in the same or opposite directions.  The preferred furnace consists of two sections 57, 58, Fig. 2 as disclosed in Specification 679,818 with axial hydrocarbon stream entering at 19.  The effluent may be passed through quenching, cooling, and separating apparatus as disclosed in Specification 607,296.  The burner or burners situated in the first section 57, Fig. 3 of the furnace has a cylindrical body 61 with bevelled end 68 and enlarged portion 66.  Air enters through tangential tubes 34, 35, while oil enters through pipe 26, and is injected into the air through spray injector 63.  The intrusion of injector 63 is adjustable, a suitable spray injector head, to impart the desirable rotation to the oil stream, is described, Fig. 6 (not shown) and may also be used on tube 19 when liquid hydrocarbon forms the axial furnace feed.  The preferred relationships of the various dimensions of the burner body are quoted.

Classes 120(1), 120(2) and 120(3) Yarn is produced by subjecting a card sliver to three drafting passages, packaging the product of the last stage thereof on a conventional speedframe bobbin, the roving so produced being 0À28 hank or coarser (cotton count) with twist factor 0À7 or less, and subjecting such roving on the bobbin to a ring-spinning operation including a draft of at least 40. A speed-frame on which the third draft is effected comprises three pairs of rollers with tension draft only in a first fixed zone and a variable draft in the back zone. The back pair of rollers is positioned to cause upward deflection of the sliver as it passes from a guide at the rear of the drafting system to the middle pair of rollers, and the upper back roller is adjustably set rearwardly of the lower thereof in order to improve fibre control. The draw-frame sliver may be coiled in cans rotating alternately through an angle less than 180 degrees so that two slivers fed side-by-side are coiled in opposite halves of the can, enabling double sliver to be creeled to each spindle of the speed-frame. High draft apparatus at the ring frame may have an initial zone of variable length (draft 4 to 8) an intermediate zone where the roving is constricted in a slightly tapered guide extending between the nip of the drafting roller of the first zone and the holding rollers of the final zone (draft up to 1À25) and a final zone comprising a double-apron unit (draft 30 or more).

A rolled wrought-iron product comprising iron having embedded therein slag masses arranged in long thin fibres is characterized in that the slag fibres are fractured transversely so that upon subjecting the product to stress in a direction transversely of the slag fibres the fractured portions thereof act individually whereby the transverse ductility of the product is materially increased relatively to the transverse ductility of a similar product with unfractured slag fibres. The reduction of the wrought iron is effected largely at temperatures below the temperature at which the slag fibres lose their plasticity, i.e. largely below 1900‹ F. It is preferred to effect one-half or more of the reduction at temperatures below 1900‹ F. The thickness is reduced by rolling below the specified temperature at least 10 per cent and, preferably, at least 50 per cent, the slag fibres fracture or kink into a series of slag masses which are aligned in the direction of rolling. After rolling the wrought iron may be annealed either at temperatures above 1900‹ F. or below. Fig. 1 is a representation of a photomicrograph at one hundred magnifications of a section of conventionally-rolled wrought iron, the section being taken parallel to the direction of rolling while Fig. 3 shows a similar section of wrought iron produced according to the invention.
