Granted: 1901-07-13
Abstract: 13,199. Muirhead, F. L., and Edgar, R. H. July 21. R÷ntgen-ray apparatus.-In locating the position of a foreign body by means of R÷ntgen rays, the vacuum tube Z is adjustably mounted on a slide p having scales to denote the movement to the right or left of the zero position. Above this is a skin window l on which the object to be examined rests. Above the object, and in proximity with it, is a graduated frame 5 in which slides a fluorescent screen 6. When the tube and the screen are at the zero of their respective scales, a central transverse line in the screen, and the point of maximum effect in the tube will be in the same vertical plane. The tube and screen are then moved to the right or left, both the same distance, until the shadow of the foreign body falls on the central line of the screen. ' Then the tube alone is moved until the shadow falls on one of two lines parallel with and equidistant from the central line on the screen. The tube is next moved in the opposite direction, until the shadow falls on the other line. The point of intersection of the lines drawn on a vertical plane from the extreme positions of the tube to the lines on the screen on which the corresponding shadows are cast, will represent the location of the foreign body, and its distance from the screen, and thus its depth in the object, can be readily calculated by means of a graphic representation or otherwise. Fig. 7 shows a device for this purpose, in which the points 15, 16, at which the legs 25, 26, are pivoted, represent the two equidistant lines on the screen, the edges of the legs representing the lines drawn on a vertical plane, as stated. By means of suitable scales at the back of the legs, as shown, the distance of the point of intersection 27 from the screen can be read off. While the foreign body may be thus located by any R÷ntgen-ray apparatus, that shown in Fig. 1 is preferably used. It consists of two boxes a, b, in which the various fittings can be stored, the lids c, d of which serve, when opened and temporarily supported by legs e, as a couch on which a person to be operated upon, or inspected, reclines, inner lids g, h and cushions 17 being also provided, and arranged as shown. The frame 5 has hinged legs 7, which fit in slots in the lid c and are suitably secured in position by catches.

Title: Improvements in and connected with Alternate Current Motors
Inventor: LIGNIERES RENE DASSY DE
Filed: 1901-01-25
Granted: 1901-11-16
Abstract: 1788. LigniÞres, R. D. de. Jan. 25. Electric locomotives and motor vehicles.-Relates to monophase and polyphase alternating-current motors, adapted for propelling vehicles, and to means for controlling the operation thereof. The speed of the motor c is varied by changing the number of its poles, and further variations are obtained by revolving the field magnet c either in the same direction as the armature a or in the opposite direction. These changes are brought about by moving a sliding contact bar m over a series of fixed contacts, 1 to 27, arranged in the manner shown, which movement may be effected by means of a screw. During the passage of the contact bar over the contacts 2 to 8, the secondary coils n, o of the supply transformer are connected in parallel, and current is supplied to the motor through the rings d,f and e, g so as to produce four poles. The number of sections of the coils n, o, included in the circuit is first increased and then diminished until on the bar m reaching the contact 9, the circuit is broken. In passing over the contacts 10 to 17, the contact bar gradually connects the coils n, o in series, and current is supplied to the motor through the two rings d,f, thus producing a bi-polar field and a consequent increase in the speed of the motor. While the contact bar is passing from 18 to 21, current is gradually supplied from a suitable source l to the continuous-current motor j, which thereupon rotates the field magnet of the main motor in the same direction as its armature and produces a further increase of speed. By moving the bar m over the contacts 22 to 27, the direction of rotation of the field magnet is reversed, and the armature may thus be quickly brought to rest. For electric traction, a motor constructed and operated as described is mounted in bearings in a bogie frame. The two axles carrying the bogie wheels are mounted in the same frame, and are both driven through spur gearing from each end of the armature shaft.

Abstract: 5586. Johnson, G. W., [Soc. Anon. des Etablissements Weyher et Richemond]. March 16. Valve gear; stop gear.-Consists of linkage valve gear for operating drop, Corliss, or piston slide valves, in which a sudden release and closure of the valve by means of a dash-pot takes place, but without actual disconnection of the parts. Fig. 1 shows the application to rocking or Corliss valves. On the valve spindle a is fixed a lever by which on one side it is connected to a dash-pot by the rod n, and on the other side to a short link g by a rod f. The link g is connected to a rocker r, and thence through the rod e to the wrist-plate d. The end of the link g during the opening of the valve rests on a fixed incline h, disposed so that the centre o always lies below a line joining the points o', p. But, to effect the release and closure of the valve, a movable incline i, pivoted at j and adjusted by the governor, is provided. The end of the rod f slides on the incline i, and, as soon as by reason of this the point o is pushed above the line o', p, the valve is free to close under the influence of the dash-pot. A supplementary incline t and loose frictional pawl s are provided, to ensure release during the return stroke, if it does not occur during the outstroke. The movable incline is provided with a finger v, for putting the gear out of action on the entire collapse of the governor. A modification especially adapted to piston slide valves is also described.
