Title: Improvements in Feed Water Heaters for Steam Generators.
Inventor: LANPHEAR LEWIS CASS
Filed: 1899-08-22
Granted: 1899-09-23
Abstract: 17,023. Lanphear, L. C. Aug. 22. Feedwater, heating.-The water is heated in two stages, first in an inner and second in an outer chamber of the heater. The first heating is preferably produced by the exhaust steam from the main engine, and the second by the exhaust of separate air and feed pumps ; but a portion of the live steam may in some cases be used. The heater consists of two concentric cylindrical casings. In the arrangement shown in Fig. 1, water from the feed-pump c passes just through the coil g in the inner casing and then through the coil h in the outer casing, the first coil being heated by the exhaust steam on its way to the condenser a, and the second by the exhaust of the air pump b and the feed-pump c. Fig. 2 shows a modified arrangement, in which the exhaust steam traverses the heating-pipes i, while the water passes through the body of the inner compartment before entering the outer coil h.

Granted: 1901-01-19
Abstract: 3691. Wallace, J. H. Feb. 26. Screening potatoes.-The machine comprises a supporting-frame A, and a sifting-frame D provided with wheels d running on tracks C. Springs p<1> limit the reciprocatory movements of the frame D. The frame D is supported by metal straps d' so that it slopes downwards towards one corner. To the inside of the frame D is fixed a screen which separates earth from the small potatoes. This screen is provided with an opening in the middle, or towards one side, for the discharge of the small potatoes by the screening-chute H. The portions of the above screen in the neighbourhood of the straps d' are replaced by sheet iron to keep the wheels d free from earth. To the top of the frame D is hinged at j a frame J within which is a screen J<1>, suspended by chains N. The screen J<1> serves to separate the seed potatoes from the small ones, the seed potatoes being discharged by a chute k. The frame J can be shaken on its hinges j by means of a handle at the rear. In using the machine, a shovelful of potatoes is placed in an ordinary circular hand screen resting on the bars L, this screen serving to separate the market potatoes from the seed and small ones. By stopping the shaking of the sifting-frame, bad potatoes can be picked out from both the hand and seed riddles. An additional hinged riddle may take the place of the circular hand-screen.

Title: Improvements in Means for Generating or Converting Alternating Electric Currents.
Filed: 1900-08-29
Granted: 1900-12-22
Abstract: 15,378. British Thomson-Houston Co., [Lunt, A. D.]. Aug. 29. Converting alternating and direct currents; distributing; transformers. - Relates essentially to converting alternating currents of one frequency into currents of another frequency or phase, means being provided for maintaining an uniform frequency and so prevent " hunting " in synchronous motors &c. The Figure shows one arrangement for converting a simple alternating current into one of different phase. 1, 2 are the mains in which single-phase electromotive forces are maintained. M is a synchronous motor geared to the frequency or phase changer P. This consists of field magnets 3 and two armatures 6 and 7. The one 6 is of the squirrel cage type, and the other 7 has a definite winding which is tapped at places according to whether single or other phase currents are required. The armature 7 is driven by the motor M at a higher or lower speed than synchronism, while the squirrel cage is rotated either in the same or opposite direction. By suitably varying the speed, the machine may be caused to act as an induction generator. The theory of the action of the apparatus is described in the Specification.

The cycle may be varied by altering the time of closing of the exhaust, valve. The engine is suitable for motor cars. The valve S may be used as an admission valve, and the valve S<1> operated mechanically to control the exhaust.
