Patent GB-190008946-A (GB)
Title: Improvements in Apparatus for Supplying Oxygenated Air to Rooms and Apartments.
Inventor: WRIGHTNOUR JOHN SPRATT
Filed: 1900-05-15
Granted: 1900-07-07
Abstract: 8946. Wrightnour, J. S. May 15. Oxygen.-Consists in evaporating in a special manner nitrogen from liquid air, and utilizing the remainder when evaporated for oxygenating the atmosphere of auditoriums, hospital wards, private apartments, &c. Liquid air is passed into a container 3, in the bottom of which is formed the receptacle 5. The lower portion of the container around the receptacle is sealed hermetically, and constructed of and covered by materials not readily conducting heat, as, for instance, lead, glass, wool, &c., or glazed tiles with hollow or porous interiors into which liquid air or gases therefrom may percolate. The upper part of the container is formed of good heat-conducting material, so that, on the liquid air flowing from the receptacle 5 over the bottom 4, the nitrogen evaporates first. This nitrogen is first drawn off, after which the remaining oxygen is passed through suitable pipes to the apartments to be oxygenated. In order to heat the oxygen as it passes to an apartment, a metallic piece is inserted in the flexible pipe which conveys the gas. For supporting and tilting the container during the operation, the stand shown in Fig. 3, having the pivoted back 26 and bottom 25, may be employed, the inclination being dependent upon the position of the rod 27 on the racks 28.

Patent GB-190101049-A (GB)
Title: Improvements in or relating to Regulating Devices for Induction Electric Motors.
Filed: 1901-01-16
Granted: 1902-01-16
Abstract: 1049. British Thomson-Houston Co. and Meyer, H. S. Jan. 16. Switches; transformers.-Relates to automatic regulating or controlling devices for induction motors. The devices are designed to diminish the magnetizing-current when running light without diminishing the starting-torque or full load capacity of the motor. Fig. 1 is a diagrammatic representation of the device, in which M designates a three-phase motor, A, B, and C the mains of a three-phase supply system, and S the main switch. The regulator consists of a single transformer having three windings d, e, f connected at one end to a common conductor 4. Each winding is provided with a number of contact terminalsp, with which engage contacts carried by a threearmed lever o. The contacts are connected to the motor terminals by conductors 5, 6, 7. A spring m normally retains the contact-lever in the position shown in Fig. 1. The movements of the contact-lever are effected by a solenoid k placed either on one of the motor circuits or in one of the main circuits 1, 2, 3. A dash-pot n is also connected with the contact-lever ; it is provided with a small perforation v and a large one v<1>, so that it is only effective during the first part of the movement of the lever. The regulator effects a variation in the potential at the motor terminals in accordance with the load. When running on no load or a light load, the spring m retracts the contact-lever so as to reduce the potential at the motor terminals, and therefore reduce the magnetizing-current. If load is thrown on the motor, the increased current through the solenoid k attracts the core i and increases the potential at the motor terminals. In a modification of the device, the solenoid does not act directly on the contact-lever but upon a switch arm balanced between two sets of contacts, so as to close the circuits of a small three-phase motor which drives the contact-lever. During variations of load on the main motor, the switch-arm is constantly shifting, so as to reverse the movements of the small motor and regulate the potential at the terminals of the large one. The contact-lever is connected with the aforesaid switch-arm in such a way that the latter is brought to its balanced or open circuit position whenever the contact-lever is at either of its extreme positions.
