Title: Improvements in Corliss Valve Gear for Steam Engines.
Inventor: SCHOFIELD HENRY
Filed: 1905-12-09
Granted: 1906-05-10
Abstract: 25,627. Schofield, H. Dec. 9. Valve -gear.-To prevent the crushing or grinding of the edges of the dies or catches of a releasing-gear, they are bevelled, and the catch is withdrawn from the other die by togglelevers. The lever c mounted on the valve spindle a carries a die n engaging a detent i, operated by toggle-levers j, k. The lever k is mounted on a pin passing through a box f secured between two levers b, loosely mounted on sleeves co-axial with the spindle a. The toggle-levers are kept straight by a spring piston m, acted on by a spring l, until a lever on the pin g comes in contact with a cam block, the position of which is adjusted by the governor. The joint then knuckles, its motion being steadied by a spring buffer r, and the lever c is released, and turns under the action of a spring and dashpot, the catch i riding on the surface c<3> of the lever c. If the spring fails to close the valve, screws z passing through the levers b engage lugs c<4> on the lever c and so close the valve. At the end of each stroke, the piston m comes in contact with a piston y acted on by a strong spring which assists the spring l in straightening the togglelevers.

Title: Improvements in or relating to Open-work Knitting.
Inventor: SCHIESSER JACQUES
Filed: 1906-01-29
Granted: 1906-08-02
Abstract: 2253. Schiesser, J. Jan. 29. Knitted fabrics.-Relates to the production of open work or like fabric on the French circular machine by spreading out some or all of the loops of an open-work course until each spread-out loop hangs from one or both of the adjoining needles. A long-loop course having been made, the loops from needles 3, Fig. 2, are picked up and placed over needles 2, 4, so that each open -work loop hangs from three needles. If, as shown in Fig. 6, the alternate loops of the open-work course are spread out, the bars a<1>, a<2> of adjacent open-work loops will overlap the plain loops b, giving a twisted-loop effect. The succeeding course c, which is of ordinary length, can be worked in the ordinary way, as shown in Fig. 6, or the needles 3, Fig. 9, from which the open-work loops were taken, can be mispressed and a tuck-stitch made as shown; or, again, the open-work loops can be pressed off the needles 3 previous to the laying of the thread c. In the parts of the open-work course where openwork is not desired, to avoid the bad appearance of plain long loops, each one of the latter is hung over the left-hand adjacent needle, as shown in Fig. 10, by means of a sinker-wheel apparatus by which the appearance of a course of twisted loops is obtained.

Title: Process of Producing Ammonia from Nitrogen Compounds.
Filed: 1907-04-23
Granted: 1908-01-16
Abstract: 9407. Krauss, C., and Ges. fiir Stickstoffdunger. April 23. Ammonia.-Ammonia is produced by the action of calcium chloride and water on cyanamides such as calcium or sodium cyanamide. Powdered calcium cyanamide, for instance, is mixed to a paste with a strong solution of calcium chloride. The paste stiffens on stirring, and is then broken into egg-sized pieces and heated in a retort, ammouia being evolved. Or the nitrogen compound may be broken into pieces, impregnated with calciumchloride solution, and heated in the same way, or powdered cyanamide mixed with powdered calcium chloride may be heated with water or steam. To prevent decomposition of the ammonia by the hot walls of the retort, steam may be introduced towards the end of the reaction, or, when the operation is continuous, the ammonia may be sucked off in the direction in which the material to be treated passes through the apparatus.

Granted: 1909-02-08
Abstract: 2824. Falkenthal, E. Feb. 7. Transformers; converting alternating'and direct currents; switches.-In apparatus for transforming direct into alternating current, or alternating current into pulsating direct current, and specially applicable for the generation of telephone ring- ing currents, a transformer is provided wit h two primary windings p<1>, p<2>, through which, when alternating currents are being produced, the current from the battery b is alternately led by means of a contact-arm i on the vibrating polarized armature a, which works in conjunction with the core e of the transformer. Alternating currents are thus induced in the secondary coil s, the frequency of which currents may be altered by varying the position of the tuning weight r on the contact-arm i. When alternating currents are to be converted to direct current, the alternating currents flow in the winding s, and the pulsating direct current is produced in the part of the circuit which is common to both primaries. The armature and contact-maker are so constructed as regards inertia &c. that contact at c<1>, c<2> is made at the moment when the electromotive force in the coils p<1>, p<2> is zero.

Granted: 1908-10-08
Abstract: 13,527. Bosch, R., [Firm of]. Sept. 7, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Gas and like engines, igniting in. Pairs of electromagnetically-separated sparking-plugs, connected in series or parallel, are used to form sparks simultaneously in two cylinders which are respectively charged and empty. Fig. 2 shows a diagrammatic view of the connexions in one form of apparatus for a four-cylinder engine. The armature winding a', a<2> of the magnets is halved by an earthed connexion and is connected at each end to the contacts 1 ... 4 of a distributing-switch. These contacts are connected to the earthed terminals of the sparking-plugs d' . . . d<4> as shown. When the short-circuit of the armature winding is broken by the interrupter c, a current passes through the plugs d<1>, d<4> or through the plugs d<2>, d<3>. The armature winding may be a single winding, a divided winding in series or in parallel, or two separate windings in series or in parallel, each having one end earthed. Fig. 3 shows one arrangement of the distributing switch and the interrupter. Two metal segments e', e<2> revolve with the armature and are connected to the armature coils. The segments are engaged by fixed carbon brushes 1 . . . 4 connected to the sparking-plugs, and also by the rotating interrupter contacts f, g. In a modified form the sparking-plugs are connected to four metal segments on a fixed disk, and are operated by a pair of rotating carbon brushes connected to the armature winding and the interrupter contacts. The metal segments also may be formed on the periphery of a cylinder and may rotate or be fixed and engaged by rotating brushes. A battery ignition may be used in place of the magneto-ignition, also any known means may be used for timing the ignition. When the pairs of plugs are connected in parallel, a normallycontrolled sparking-apparatus or battery device is used, but the distributor has only half the number of contacts that would be needed to cause a separately-timed spark in each cylinder.
