Patent GB-189809805-A (GB)
Title: Improvements in Binoculars, Telescopes, and other Optical Instruments in which it is desired to Obtain a Rectified Image.
Inventor: HUET HENRI LOUIS
Filed: 1898-04-28
Granted: 1899-03-04
Abstract: 9805. Huet, H. L. April 28. Optical instruments.-Two irregular tetrahedra or triangular pyramids of optical glass are interposed between the object glass and eye-piece of a telescope, field glass, microscope, or the like instrument to reflect, and reverse or rectify the image, so that an astronomical or simple eye-piece can be used instead of a terrestial or compound eye-piece. Fig. 1 shows one of the tetrahedra in plan and elevation. Fig. 10 shows the tetrahedron with the trihedral angles cut off to save space. The vertical face M N S is in shape a rectangular isoceles triangle ; the faces S M P and S N P are inclined to the vertical face at an angle of 45‹ ; and the fourth face. M N P is horizontal. The rays of light enter the vertical face at right-angles ; they are reflected downwards in an inclined direction by the face S M P on to the horizontal face, which reflects them up to the inclined face S N P, which, in turn, reflects them through the vertical face. The image, indicated by the crossed arrows a b and c d in the diagram, is rotated through an angle of 90‹ by the successive reflections. A second tetrahedron is arranged with its vertical or receiving-face parallel to the vertical face of the first tetrahedron in order to rotate the image through another 90‹ in the same direction, that is, to reverse or rectify the image. Fig. 4 shows the application of the invention to a binocular glass. A ray of light indicated by the dotted line o o passes through the object glass, is reflected by the six reflecting-faces of the two tetrahedra a, b, and emerges through the eyepiece g. The halves of the binocular glass are connected by telescopic cross-bars k, k<1>, adjustable for the purpose of spacing the eye-pieces &c. by means of a milled head l and pinions. The focus is adjusted by a second milled head m. A diaphragm h is arranged between the reflecting - apparatus and the eye-piece, and the reflecting - apparatus i s protected by a flat sliding case. By this invention, the instrument can be made shorter in length, flat in shape, and, in the case of a binocular glass, an increased stereoscopic effect is obtained.

Title: An Acetylene Gas Lamp.
Inventor: NELSON WILLIAM OTTERBEIN
Filed: 1899-12-23
Granted: 1900-02-17
Abstract: 25,492. Nelson, W. O., Houghton, L. S., and Miller, E. Dec. 23. Acetylene lamps.-A cycle or like lamp is formed with a bellows-like gas chamber 14, the movement of which automatically controls the water supply, and partially rotates the removable wire carbide holder 45, to expose fresh carbide to the action of the water. When the lamp is started by opening the burner valve 68 and unscrewing the nut 29 to release the bar 31 from the retaining-hook 30, an adjustable spring 25, acting through the arms 22, presses inwards the movable side 17 of the gas chamber 14, which side, by means of the levers 35, 36, the rocking shaft 38, and a cam or its equivalent thereon, opens the valve 56, and allows water to drip from the pipe 54 on to the carbide contained in the wire cage 45. The gas generated enters the chamber 14, and the consequent outward movement of the side 17 and its attached levers closes the water valve 56, and by means of the lever 39, the toothed segment 42 loosely attached thereto by pins 41 and slots 43, and the ratchet 52, partially rotates the carbide holder, the backward movement of which is prevented by a pawl 60. The wires 46 of the carbide holder are indented at 46<a>, to prevent the water from trickling to the sides, and the charging-opening is normally closed by a plate 50, which is attached by the pins and slots 49, 41. Gas is admitted to the upper part of the water chamber 10 by a pipe 70, is purified by traversing the chamber 65<a> on its way to the burner 67, and escapes from the chamber 14, when the side 17 has reached its outermost position by the opening of the conical spring valve 72. The flue 69 is made sufficiently long to prevent the products of combustion from heating the lamp body, which is also kept cool by the provision of an air space 6 between the walls 4 of the water chamber and the casing 5, through which the filling-aperture 8 of the water chamber passes. Should the gas chamber 14 leak, the inward movement of the side 17 automatically closes the water valve 56. In the construction shown in Fig. 1, the valve 56 is open when the V-shaped end of the lever 58 simultaneously engages with corresponding notches in a fixed and a loose collar on the shaft 38, the collars being loosely connected together by a pin and slot.

Abstract: 9033. Mallet, J. P. Oct. 17, A.D. 1899, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Transformers.-Relates to strap coils for transformers and like electrical machines, the object being to provide a coil to serve as a wire-wound coil and to be readily applied to the core. A singlestrap coil with two commutator leads 4, 5 is shown in Figs. 1 and 2. Each turn is formed with two parallel parts 1, 2 and portions 3 curved and bent edgewise as shown. Starting with the first convolution from the lead 5, the first half 6 is on the outside of the coil, receives a half twist at the bend 3, proceeds with the second half 7 on the inside of the coil, and receives another half twist at the commutator end, after which the first half 8 of the second convolution is formed inside the part 6, and so on. The span of each convolution is thus the same throughout. After the coil is bent, it is opened for the insertion of insulating- tape between the parts, and before application to the core the parts are wound round and between with a cell 11, Fig. 7, of sheet insulating-material such as vulcanized fibre. A double strap coil with four commutator leads 15 is shown in Fig. 4. The commutator end 3 is shaped substantially as in the preceding case, but the other end 12 is bent so that the parts 13 are more nearly parallel to the plane of the coil as a whole.
