Patent GB-190023492-A (GB)
Title: Improvements in and relating to Methods for Testing Electric Circuits
Inventor: MINSHALL THOMAS HERBERT
Filed: 1900-12-22
Granted: 1901-12-21
Abstract: 23,492. Minshall, T. H. Dec. 22, Testing.-The position of a short - circuit 20 between two insulated conductors 16, 17 is determined by passing a constant current through the whole length of one of the conductors 16, and through a standard resistance 1, and comparing, by means of a volt-meter 19, the difference of potential between the ends of this resistance with that between any convenient point 21 on the'selected conductor 16 and the point of short-circuit, connection with the latter being obtained through the fault 20 and the other conductor 17. The resistance between these points, and the position of the fault, can then be calculated, the resistance per unit of length of the selected conductor 16 being known. The circuit to convey the constant current through the selected conductor 16 is completed by a third conductor or by earth connections 18, 7, and includes a fuse 2, a rheostat 4 to adjust the current, and an indicator 6 to show its constancy. Currents of which the relative strengths are known may be used in the standard resistance and the selected conductor. Instead of measuring the difference of potential over a standard resistance, the current used may be measured directly by an am-meter 6 in the circuit, or the differences of potential between two separate points on the selected conductor and the point of short-circuit may be compared by the volt-meter.

Title: Improved Means for Propelling Ships, and for Ventilating the Holds, Cabins and State Rooms thereof.
Inventor: TULLIS JOHN KEIL
Filed: 1901-03-20
Granted: 1902-04-19
Abstract: 5843. Tullis, J. K. March 20. Screw propellers for propelling and steering steam ships, and for use as auxiliary propellers for sailing-vessels, comprise a series of screws a, a<1> ... a<5> of small diametermounted upon one or more light shafts A, B working at high speed, in the case of steamships, in channels C, D, Figs. 1, 2, and 3, open to the sea. Loss of power consequent on the screws leaving the water is thus prevented, and vibration is minimized by driving the shafts by belts I, J from large drums H, G driven directly from the engine. The vessel can be turned in a little more than her own length by driving the port engines forward and reversing the starboard engines, or vice versÔ. As auxiliary propellers for sailing-vessels in rivers and canals, or during calms and light head-winds, series of screws mounted on short light shafts are arranged in channels C', D', Fig. 7, in the sides of the vessels, the openings to the channels being closed at other times by sliding plates N. The shafts are driven by belts from electric motors or high-speed engines.

Patent GB-190114613-A (GB)
Title: Improvements in Return Steam Traps or Boiler Feeders.
Inventor: HALLAS JOHN
Filed: 1901-07-18
Granted: 1902-06-05
Abstract: 14,613. Hallas, J. July 18. Feedwater, supplying and controlling.-Relates to a return steam trap or boiler feeder for receiving and returning to the boiler water of condensation received from a steam circulating system. The closed vessel 1 is provided with the steam inlet 24 and the boiler outlet 26, and has within it the internal vessel 3, with its tile float 8, and the float 6, controlling the valve 5 at the bottom of the vessel 3. The float 8 is linked to the rock-shaft 10 and is counterbalanced by the adjustable weight 22 on the lever 21. When condensed water enters the trap, it first closes the valve 5 through the float 6, then it overflows or passes by the siphon pipes 25 into the vessel 3 causing the linkage mechanism 15. 16, 17, and 18 to open the boiler steam valve 19 and close the exhaust valve 20. The boiler steam forces the condensed water through the check valve 26 to the boiler. A regulating nut and screw 27 may be employed to adjust the movement of the exhaust valve 20. A water gauge 23 is fitted to the apparatus.
Patent GB-190120083-A (GB)
Title: Improvements in Pneumatic Despatch Tube Apparatus
Inventor: PIKE OTTO SAMUEL
Filed: 1901-10-08
Granted: 1902-03-06
Abstract: 20,083. Pike, O. S. Oct. 8. Pneumatic despatch apparatus.-Consists of a terminal, which can be used for either sending or receiving, according as an air-compressor is worked at one end of the transit tube or the other. It takes the form of a drum g, which contains two T-valves b, h, and is laterally connected to a compressor 113 or the atmosphere at d by a breeches pipe 114, 91, 50 containing a regulating band-valve 70. When arranged for sending, the cranks 36, 38 of the T-valves h, b are connected by rods 37, 39 to bell cranks 26, 30, which are operated in succession, as named, and reversely by an intervening lever 23 which is actuated by a piston 18 in a cylinder 19. A sector 32 rocking with the central lever locks the one bell crank while the lever is acting on the other. A directing- valve a in the breeches pipe is connected to the T-valve b which controls communication between the drum and the transit tube, the link and crank shown being adjustable in length so that the initial driving-pressure can be varied by division of the air pressure. Having inserted the carrier through the open valve h at the atmosphere end f of the drum, a hand-cock 4 is turned from the snifting position shown in Fig. 8 to connect a pressure pipe q with a tube s, which leads to a small cylinder u. A piston accordingly shifts the distributing-valve 3 of a somewhat larger cylinder 8, the piston 9 of which in turn shifts the distributing-valve 10 of the main cylinder 19. The valves are accordingly reversed, and a slotted link 41 lifts a stop i to let the carrier depart. Meanwhile, the smallest cylinder is snifted by the hand-cock returning to its original condition, and the piston in it is returned by a spring. When the carrier has left the terminal, the air pressure separates two flaps in a lateral chamber 55, and these, acting as a lever, reverse the small distributing-valve, following which the main distributing-valve is reversed, and the terminal is prepared to receive another carrier. The handcock is returned to the snifting position by a spring, because a spring bolt, which holds it after turning, is drawn by air pressure coming through the pipe x after the first piston has moved. To convert the terminal into a receiver, the directing- valve in the breeches pipe is unlinked, and left closed while the T-valves are reversed by the hand-cock. The outer T-valve is then turned from the connecting-rod of the sending-mechanism to the connecting-rod of a piston in a second main cylinder 87, which opens and closes it to let the carrier emerge.
