Abstract: 1,028,116. Automatic control of speed and tension. F.SHIBATO. Sept 15,1964 [Sept 30, 1963; Oct 1, 1963;Oct 5, 1963;Oct 23, 1963], No. 37568/64. Heading G3R. [Also in Division H2] The speed of a polyphase, wound rotor induction machine 1 is controlled by adjustment of the field current of at least one of two D.C. machines 2, 3 connected in series to its secondary windings via a convertor 4. One of the D.C. machines is mechanically coupled to the induction machine and the other to a fourth rotating machine 5. In the arrangement shown, 1 is a motor, 5 is normally an A.C.generator and 2 and 3 may be excited for either motoring or generating. The motor 1 may be dynamically braked by applying D.C. or reverse A.C.,the machine 3 then acting as a motor energized from 1 and 2. The convertor 4 may comprise valve, metal or semiconductor rectifiers, controlled or otherwise, a magnetic amplifier, mercury arc rectifiers fed via a variable transformer (Fig. 9, not shown), or a rotary convertor. (Fig. 3, not shown). In another arrangement (Fig. 4, not shown) there are a plurality of induction motors 1,41 each mechanically coupled to a D.C. machine 2,42, the wound secondaries, convertors and D.C. machines being paralleled and connected to a single D.C. machine 3 coupled to an A.C. generator 5. Adjustment of the field of the single D.C. machine 3 varies the group speed of all the induction motors, while adjustment of the fields of the individual D.C. machines controls the speed of its associated motor only. In another embodiment (Fig. 8, not shown) both 5 and 3 are driven by a prime mover 20. In the arrangement of Fig. 2 (not shown) the induction machine 1 is a dynamo-electric coupling, driven by a prime-mover 20, and its output speed to a load 23 is controlled by adjustment of the fields of D.C. machines 2, 3. In a further arrangement (Fig. 5, not shown), 1 and 2 are A.C.and D.C. generators driven by a diesel engine, waste gases from which produce steam for a turbine driving 5, also a generator; 3 operates as a motor, energized from 1 and 2,and assists in driving 5. The A C output of 5 is used in parallel with an auxiliary diesel driven AC. generator. In an embodiment described in relation to Fig. 6 (not shown) 5 is a generator whose speed is kept constant by controlling the field of 2 (generating) or 3 (motoring) in response to a tachogenerator 56. 1 is an A.C. generator driven by a prime mover 55. The invention is also applied to an arrangement for keeping constant tension in a web W, (Fig. 7 not shown). The speed of reel motor 1 is adjusted to compensate for the radius of the material on reel 69 by control of D.C. machine fields 6, 7. The field 7 is controlled by a device 57 which compares current flow between the machines at 61 with a reference 59, with correction for acceleration by a device 62, 63. The field 6 is controlled by device 58 which compares the output of capstan tachogenerator 65 with the voltage across D.C. machine 3.

The carriages of the table are articulated by lugs pivoted at 52.  Attached to pivots 52 are links 51 having rollers 53 which mesh with sprockets 50  to drive the table.  To the forward end of each carriage is attached a removable metl plate 14 (Fig. 7), the upper surface of which forms the bottom surface of the rib 16 between a pair of juxtaposed shoes 7.  Each shoe 7 has a vertical rod 22 attached to its underside, the rod being mounted within a sleeve 23 to which it is attached by a ball and groove arrangement 28, 29.  The lower end of the sleeve 23 is attached to a carriage 27 which has a wheel 26 mounted thereon.  The wheel 26 rides down the surface of a cam 25, just before the end of the upper straight part of the guide 10, causing the sleeve 23 to be moved downwardly against the action of a spring 24 to withdraw the shoe 7 from contact with the glass sheet.  To remove the shoe 7 from the carriage 8 a ring 35 in the lower carriage 27 is forced upwardly against the action of a spring until an annular groove 36 therein is positioned to receive the balls 28 from the groove 29 in the rod 22.  To produce glass sheets of constant width, a sheet is rolled out which is wider than the width of the shoes 7, this extra width being made up by side pieces having longitudinal cutters attached thereon to remove the waste glass. Where necessary some of the shoes may incorporate transverse cutters mounted between shoe 7 and the metal plate 14 (Fig. 12, not shown). Various embodiments are described with reference to the drawings of mountings for the shoes 7 and mechanism for driving the continuous table 5.  The apparatus may have two or more parallel sets of shoes and carriages with longitudinal grooves between each pair of sets to four longitudinal ribs on the glass sheet.

Abstract: 1,025,323. Packaging-machines. ALOFIN VERWALTUNGS, and FINANZIERUNGS A.G. Oct. 5, 1962 [Oct. 5, 1961; May 23, 1962], No. 37726/62. Heading B8C. [Also in Divisions B4, B5 and B6] Cakes of kneadable material formed in a reciprocable mould 4 (see Division B5) are expelled from the mould by a die 5 at a position above a box 26 on a slide 25, a length of sheet material 8a being interposed between the mould and the box 26, by means of reciprocable grippers 14, and subsequently wrapped round the cable. The mould 4 receives the cake material from a hopper 2, Fig. 2 (not shown), the mould base 7 being adjustable to vary the cake size. As the grippers 14 move forward, a tappet roller 19 causes the pivoted top member of the grippers to close and engage the material 8a, e.g. paper, which is then drawn out as the grippers return. A brake 9 is operated to hold the roll 8 causing the material 8a to tear along a perforated line. To avoid damage to the cake as the die descends, a blade 27 forming the front wall of the box 26, is pivoted through 90 degrees. A folding member 29 on the slide 25 is advanced to fold one top flap of the wrapping material, the slide 25 then moving so that a roller 28 folds the other top flap, and members 30 fold the side flaps. In a modification, Figs. 2a and 3a (not shown), the base of the mould 4 is grooved to receive the side walls thereby preventing the cake material from escaping laterally. Further folding slides may be provided, Figs. 6a-6c (not shown).

Filed: 1929-12-11
Abstract: 339,791. British Thomson-Houston Co., Ltd., (Assignees of Nickle, C. A.). Dec. 24, 1928, [Convention date]. Exciting.-The excitation arrangements of a synchronous alternating-current motor comprise means controlled jointly by an electrical condition of the excitation circuit, such as the excitation voltage, and the alternating current supplied to the motor for maintaining a predetermined relationship between the electrical condition and the current supplied to the motor. The relationship is :-(field current)<2>-(armature current)<2> = a constant quantity and it is shown in the Specification that by increasing or decreasing the field current as the load current of the motor increases or decreases respectively, the " dropping-out " power taken by the machine is made greater than it would be with constant excitation, i.e. a smaller motor than normal may be used for a given duty, a substantially constant power factor being obtained at all loads. In the form shown, the fields 4 of the motor 1 are energized from a machine 5, the fields 6 of which are energized from a sub-exciter 7. A resistance 8 in parallel with the sub-exciter is intermittently shortcircuited by a Tirrill type of regulator 10 having two plungers 13, 14 within magnetically opposing solenoids 11, 12 respectively carrying currents proportional to the excitation voltage at 4 and the motor armature current. The spring 17 of the regulator and the adjustable resistances' 12', 16 in the solenoid circuits are so set as to give any desired relationship between the excitation and armature current of the motor, for instance so as to establish in the machine a predetermined internal voltage which neutralizes the armature reaction and ensures constancy of the flux linkages of the field winding. Any subsequent increase of the motor load, by increasing the weakening action of the solenoid 12 on the solenoid 11, causes the spring 17 to close the contact 20 and increase the excitation at 4 until the pull of the solenoid 11 counterbalances that of the spring. A decrease in the motor load decreases the excitation by a similar inverse action. Specification 281,243, [Class 38 (iv), Electric supply and transmission systems &c.], is referred to.
