Title: Improvements in and relating to Dynamo Electric Machines.
Inventor: ALEXANDERSON ERNST FREDRIK WER
Filed: 1908-01-10
Granted: 1908-10-29
Abstract: 661. Alexanderson, E. F. W. Jan. 12, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Dynamos, alternating-current; armatures; commutators.-In commutator machines, and more especially for alternating-current machines, having more than two coils per slot, the leakage reactance between adjacent coils is unified around the whole armature to improve the commutation. This is effected by so arranging the commutator connecting-leads that leakage reactance exists between the leads of coils lying in the same slots (and so having no reactance), while the leads of coils lying, in part, in different slots are arranged to be without such reactance. Fig. 1 shows a winding having four coils per slot, the commutator leads, shown in dotted lines, being preferably of high resistance and placed at the bottoms of the slots. The circuit between the segments C<1>, C<2> consists of the two leads between the armature teeth D<4>, D<5>, and the two conductors between the teeth D<1>, D<2> and D<6>, D<7>. The circuit between the segments C', C<3> consists of the lead between the teeth D<4>, D<5>, the conductors between the teeth D<1>, D<2> and D<7>, D<8>, and the lead between the teeth D<4>, D<5>. Thus, corresponding members of the two circuits lie in the same slots, excepting the right-hand conductors, which are separated by the tooth D<7>. The flux through this tooth accordingly determines the leakage reactance of the two circuits. Similarly, the circuits between the segments C<2>, C<3> and C<3>, C<4> have corresponding members in the same slots, excepting the left-hand conductors, which are separated by the tooth D'. In the circuits between the segments C', C<4> and C<4>, C<5>, both pairs of corresponding conductors are in the same slots, but the return leads are separated by the tooth D<5>. Thus, between each pair of adjacent coils throughout the armature, there is a leakage reactance due to one tooth. Fig. 4 shows a winding having six coils per slot, in which case the commutator leads are taken along the armature twice, and the circuits between adjacent pairs of commutator segments have their corresponding elements paired in the same slots, excepting one pair, which are separated by one tooth. Thus, the circuits between the segments C<1>, C<2> and C<2>, C<3> have one part of their return leads separated by the tooth D<4>. All the leads B may be wrapped with a magnetic covering b, Fig. 3, which may be omitted from the outside leads as shown.

Title: An Improved Process for Making Electrolytic Depositions of Chromium.
Inventor: SALZER FRANZ
Filed: 1908-01-20
Granted: 1908-09-24
Abstract: 1344. Salzer, F. Jan. 21, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Chromium, depositing.-Chromium is deposited from an electrolyte containing a mixture of chromic acid and chromium oxide in equal weights, or with less chromium oxide but not less than half the weight of the chromic acid, the proportions being maintained as constant as possible throughout the process. An acid may be added to improve the conductivity of the solution. The bath may be made by a partial reduction of chromic acid by electrolysis, or by simply mixing the oxide and acid. In the Specification in the original form, as open to inspection under Section 91 (3) (a), it is stated that the baths may be made by the partial reduction of chromic acid by purely chemical means, or by the partial oxidation of chromium salts, and that the character of the deposit may be varied by varying the concentration and the acid addition. This subject-matter does not appear in the Complete Specification as accepted.

Title: Improved Hydraulic Motor.
Inventor: BOETTCHER EMIL
Filed: 1908-02-08
Granted: 1909-02-08
Abstract: 2877. B÷ttcher, E. Feb. 8. Water-pressure engines. -The distributing piston valve is reversed by pressure water taken from the connecting ports between the distributing valve casing and the working cylinder, thereby relieving the pressure on the valve immediately reversal is effected. The working cylinder 5, No. 1, is reciprocated upon a fixed piston 1, but the cylinder may be fixed and the piston reciprocated. The fixed piston-rod 4 is connected to the frame 3 of the machine, and upon the cylinder is fixed a driving- bar 9 which oscillates a toothed wheel, shown by dotted lines, to drive washing or other machines. The distributing piston valve consists of four pistons 11 rigidly connected together, the middle two controlling the admission of water from the inlet 12 to the working cylinder through the ports 13, and the outside ones, in combination with the middle two, controlling the exit of water from the working cylinder to the exit port 14 and pipe 15, Fig. 3. At the ends of the stroke of the working cylinder, the distributing piston valve is reversed by means of pressure water admitted to the outer end of one or other of the outside pistons 11 from the connecting port 13 through ports 17, 16, 18, Figs. 1, 3, and 4, the admission of this water being controlled by piston-rods 19 arranged at each end of the exit port 14 and connected together. When the working cylinder reaches the end of its stroke, a pin 22 strikes a projection 23 on the frame 3 and shifts the piston 19, thus uncovering the port 18 to admit pressure water from the port 13 through an opening 24 into the distributing casing 10, whereby the piston valve 11 is thrown to the other end of its casing 10. The opening 24 is slightly longer than the piston valve 19 in order to allow the water behind the valve 11 to pass, on reversal, to the outlet 14 when the valve 19 is at its extreme position. Simultaneously with the reversal of the distributing piston valve 11, the port 13 is cut off from the pressure pipe 12, and the pressure behind the piston valve 19 is relieved. When the piston valve 19 and distributing piston valve 11 are reversed, part of the water behind them flows back to the port 13 and thence to the outlet 15, and when the piston valve 19 covers the port 18, the remaining water passes through a very small port in the valve 19 to the exit 14. This port is too small to interfere with the action of the valve. A modification is described in which the piston valve 19 is dispensed with, and the admission of water from the port 13 to the distributing-piston 11 is controlled by the valve itself. The port 18, in this case, opens into the casing 10, and at the end of the stroke of the working cylinder, the valve 11 is shifted by a pin striking a projection 23 on the frame 3, thus uncovering the port 18 and admitting water from the port 13 to throw the distributing piston valve to the other end of the casing. Small ports through the end pistons of the valves 11 serve to carry away water from the ends of the casing as before described.

Granted: 1909-05-27
Abstract: 16,128. Steynis, J. July 29. Aerating liquids.-Liquids are aerated by moving a downward current of the liquid againstan upward current of the gas, the liquid and gas afterwards withdrawn from the mixing-chamber by suctionapparatus and throughly mixed therein. In one form of apparatus shown in Fig. 1, liquid is drawn iuto a mixing-chamber 1 through a spraying-nozzle, and partly fills the chamber. Gas enters by a series of perforated nozzles 19 arranged at varying depths in the liquid, passes upward through the liquid, and is treated with the liquid spray. The gas and liquid pass into a second chamber 2 through pipes 4, 3 respectively, and are drawn off together through a central trunk tube 20 by a rotary pump 22 and thoroughly mixed therein. In another form of apparatus shown in Fig. 2, liquid is sprayed into the mixing-chamber, and the gas enters by a perforated nozzle 30. A partition 28 is arranged in the mixing- chamber, the liquid passing under it and being drawn off by a rotary pump 33 through a connexion 34. The gas is drawn off together with the liquid through the connexion 34, but is preferably led off through a separate pipe 35 having an outlet concentric with the pump inlet. The gas entering the apparatus may be ozonized in apparatus 10. The rates of flow of the liquids and gas are controlled by cocks in the various connexions.

Title: Improved Thermostatic Valve Arrangement for Vapourising Burners.
Inventor: AHLSELL FRITIOF LUDVIG
Filed: 1908-09-10
Granted: 1909-09-23
Abstract: 19,050. Ahlsell, F. L., and Thompson, L. 0. T. Sept. 10. Vapour lamps and burners.-Thermostatic valves for vapour burners, for illuminating or beating, are so constructed that relative movements between the valves and their seats during pre-heating do not occasion the opening of the valves until the vaporizers attain a temperature high enough for thorough vaporization of the fuel. The vatve-rod 6 is screwed or otherwise adjustably secured at its upper end within the vaporizing-tube 1, and, as shown in Fig. 2, its lower end may be made conical as at 9 with a diminished cylindrical extension 8 fitting tightly within a countersunk hole 4 in the valve seat 2, which forms a partition across the tube. The end of the valve-rod 6 may be equal to or larger than the upper part of the rod in diameter, and may have the conical portion 9 below the seat 2 when, the materials for the rod and tube having been suitably selected with regard to their coefficients of expansion, the relative motion is oppositely directed as shown in Fig. 4. In the form shown in Fig. 3, the valve-rod is tubular at its lower end and fits tightly over a tube 10, and may have perforations 12. In all forms, the amount of initial relative movement between the valve and seat necessary for the opening of the valve may be adjusted by screwing the valve-rod 6 or otherwise.
