Title: Improvements in Regulating Dynamo-electric Machines.
Filed: 1900-08-29
Granted: 1900-12-31
Abstract: 15,379. British Thomson-Houston Co., [Steinmetz, C. P.]. Aug. 29. Transformers; converting alternating and direct currents.-Relates to the regulation of alternating- current machines, including rotary converters and the like, and comprises improvements on the system described in Specification No. 29,585, A.D. 1897. The regulation is performed indirectly by regulating the exciter, and this is effected by passing alternating currents, derived from the mains but changed in frequency, through the armature of the exciter, thereby producing an armature reaction having a component acting to vary the field of the exciter, and consequently the field of the machine to be regulated. Fig. 1 is a diagram of the arrangements adopted for the regulation of a quarter-phase generator G, the field windings F of which are supplied by the armature of a continuous-current exciter E, running synchronously therewith but having a smaller number of poles. By means of an induction machine I, also rotating synchronously with the main generator, three-phase currents of reduced frequency are supplied to the armature of the exciter, the frequency being so chosen that the polar line of the armature will normally be fixed in the space. Should the currents in the alternating system commence to lag or lead, the polar line of the exciter armature will be shifted slightly in one direction or the other, thereby increasing or decreasing the current supplied by the exciter to the field windings of the main generator.

Title: Improvements in or relating to Dough-moulding Machines.
Inventor: BAKER WILLIAM KING
Filed: 1900-10-20
Granted: 1901-10-19
Abstract: 18,765. Baker, W. K., and Baker, G. S., [Thomson, C. A.]. Oct. 20. Moulding dough.-Relates to machines for working-up lumps of dough into loaves. The dough is placed in the hopper, Fig. 3, and passes between two pairs of rollers, which press it out into a thin sheet. This sheet is fed to a toothed roller D<1> which, with the assistance of a small smooth roller D, rolls it up into a spiral form. This rolls down a plate E to a large fabric-covered drum F, which rolls it against a cylindrical plate F<4> and thoroughly kneads and works it into the form of a loaf. It then passes down a delivery plate G and drops into, or is placed in, a pan, in which it is baked. To prevent the dough from adhering to the rollers or drum, flour is sprinkled on it from hoppers S. These are perforated below and are fitted with adjustable perforated slides to regulate the supply. Brushes T, reciprocated by a crank on the arbor of the roller B<2>, ensure a supply of flour when the slide is opened. The upper roller of each pair is journalled in a frame, which is movable by means of hand-screws to adjust the thickness of the sheet. The distance between the drum F and the p!ate F<4> can be altered in the manner shown in Fig. 2. By means of a hand-screw the levers Q and Q<1> are rocked, to adjust the distance of the lips of the plate from the drum, while at the same time the bottom of the plate is raised or lowered. The drum is flanged to accommodate the longest loaf, but additional flanges can be secured inside the permanent ones when shorter loaves are to be made.

Granted: 1901-05-18
Abstract: 6261. Kando, C. de. March 25. Actuating valves and cocks.-A liquid resistance is controlled pneumatically, in accordance with the current passing through it, or any proportionate current, by a valve operated electromagnetically by such current. One form of valve is shown in Fig. 1. A lift valve 2, interposed in the air way 3 to the liquid resistance, is carried by a diaphragm 1, and normally stands open. The controlling- current passes through a solenoid 8, and tends to lower a core 5 and lever 6 in opposition to a spring 7, to close the valve. In another form, a rotatable valve is movable by an S-shaped iron armature on it turning between electromagnets carrying the controlling-current, in opposition to a spiral spring. Slide or other valves may be used. The springs may be replaced by weights, compressed air, or magnetic attraction. The apparatus may be used for starting a three-phase motor, or for other purposes.

Title: Improvements in Paddle-wheels.
Inventor: KLINE HENRY STERANICE
Filed: 1901-11-14
Granted: 1902-11-13
Abstract: 22,987. Kline, H. S. Nov. 14. Paddle-wheels suitable for use at the stern or sides of a vessel have the paddles pivoted and operated so that they assume vertical positions upon leaving the water, thereby relieving the wheel of the weight of the water which is carried upward when fixed paddles are employed. The paddles 6 with their cranks 8 and rollers 9 are so pivoted as to hang vertically by their own weight when above the water line. But, when the wheel is rotated in the direction of the arrow a, as the paddles enter the water, blocks 11 on the paddles are forced into contact with, and are held by, blocks 10 on the spokes 2. As the wheel rotates, rollers 27 on arms 25 engage with a tappet 23 on the pivoted block 21 shown on the right-hand side of Fig. 1, and, through the connecting-rod 24 and the links 19, 20 on the left, projects thecam 14,15 shown on the left-band side of Fig. 1 into the path of the rollers 9 on the cranks 8, thereby turning the paddles substantially to a vertical position with their edges uppermost and discharging the water. After the cranks have moved clear of the cam, the paddle will turn by gravity to its normal position. When the wheel is rotated in the opposite direction, the cam shown on the right-hand side of Fig. 1 will be projected outward, and that on the left-hand side will be retracted.

Title: Improvements in or relating to Automatic Coin-freed Weighing Machines
Inventor: SCHULTZE GUSTAV FRIDRICH WILHE
Filed: 1901-12-11
Granted: 1902-06-25
Abstract: 25,268. Schultze, G. F. W. Dec. 11. Weighing - apparatus of the coin-freed type, fitted with devices by means of which the user can register his estimated weight, and, in the event of the estimate being correct, receive back his penny, is shown in Figs. 2, 3, and 6. The user stands on the platform 4 connected by the bar 6 to a drum 8, which carries a balance weight 10, and the rotation of the axis 11 correspondingly affects the indicating-dial 18, which is normally hidden from observation through the sight opening 20<1> by a shutter 20. A similarly-marked dial 21 rotated by an external button 23 is set by the user so as to indicate his estimated weight. The coin is then pushed into the coin shoot 26. Coin action.-The insertion of the co:n moves the pivoted lever 27<1>, connecting-wire 28, and bellcrank lever a, and releases a pivoted lever 25, which engages with, and locks, the set dial 21. The coin drops into a pocket 27 carried by a balanced arm 41 on an axis 43, and tilts the arm downwards, causing the gearing 55 to rotate the shaft 50, the rotation being limited by a stop 19 on the dial axis 16<1>. This movement also causes the gate 47 in the coin pocket to be opened by means of the rack 48', and the coin released. The coin drops into the coin tube 35, and then into the receptacle 58<1>, unless it is diverted by the gate 33 into the return shoot 34 leading into an external basin 58. This gate is operated as follows :-The battery 61 is connected to the set dial carrying a contact 67, and a second similarly-placed contact 68 on the dial 18 registers with the first contact when the dials indicate the same amount. The battery is connected through the electromagnet 59 to the dial 18 by means of a wire 63 and rotating pin contact 65, which is closed by the rotation of the shaft 50. The energized electromagnet then draws in its armature 60, and releases the gate 33, which bars the coin tube and deflects the coin into the external basin. The tilting of the arm 41, after the insertion of the coin, allows the link 71<1> to drop, and the pivoted lever 69 to raise the shutter 20 and expose the user's correct weight.
