Title: Improvements in and relating to Electrical Measuring Instruments.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-01-15
Granted: 1903-12-10
Abstract: 1067. Carolan, E. A., [General Electric Co.]. Jan. 15. Resistances; current m e t e r s.- Shunt resistances for ammeters or other instruments are provided with means to compensate for thermoelectric forces, and for changes in resistance of instrument leads, due to temperature variations. The first compensation is obtained by attaching to the blocks 1, 2, at the ends of the shunt resistance strips 3, auxiliary blocks 4, 5 and strips 3<a>, the blocks 1, 4 being connected together electrically ; the blocks 2, 5 are separated by insulation, and are connected to the two instrument leads 6, 7. Any thermo-electric force set up by difference of temperature of the blocks 1, 2 is thus balanced in the instrument circuit by the opposing-force produced between the blocks 4, 5 and strips 3<a>. For the second compensation, the instrument leads 6, 7 are placed adjacent to a loop 8, 9 of wire of proper resistance, having a higher temperature-resistance coefficient than the leads, the ends of the loop being connected to the leads 6, 7 near the measuring-instrument, so that the loop is connected parallel to the instrument. For example, the loop may be of iron of such resistance as to take twice the current of the instrument, the leads 6, 7 being of copper. The leads and loop may be in one cable.

Title: Improvements in or relating to Drop Stamps, Hammers and the like.
Filed: 1903-02-13
Granted: 1904-01-07
Abstract: 3451. Pattinson Bros., and Slater, T. Feb. 13. Stamping; hammers, power.-Blows are automatically delivered in continuous succession, and one or more blows of varying force may be given. The hammer A is lifted by a belt C, Figs. 1 and 2, which passes between lifting-pulleys D, E and gripping-rollers E<1>, E<2>, and is held in its highest position by a detent H<3> By means of a footlever J, the hammer is released, and a projection A<2> then engages a pin M situated near the bottom of the guides, thus turning an arm O<1> and removing a catch K from rod G<2>. The rod G' is attached to a rod G, coupled to the rod F<4>, which is attached to eccentricatly-mounted bearings of the pulley D. The weight of the rod G causes it to descend, thus pressing the pulley D against the belt C and pulley E. The hammer is then raised until it engages an arm G<2> carried from the rod G, raising the latter and allowing a spring M', Fig. 6, to restore the catch K. The hammer is now allowed to fall again, and the operations are repeated. When single blows of varying force are required, the lever J is connected to a lever P P<1> mounted on the spindle 0 which carries the arm O<1>, and a handle N working in a cam-shaped end of a bracket M<7> is given a partial turn, thus drawing back a pin M<3> from the arm O<1>, and allowing the spring M<2> to remove the catch K, the rod G being now supported by the arm G<3>. On depressing the lever J, the hammer will fall and the end P of the lever P P<1> will support the rod G, the hammer being raised only when pressure is removed from the lever J. The hammer may be stopped at any point on its upward course by depressing the lever J, and thus blows of varying force may be delivered. When working automatically, the lever P P<1> is preferably removed.
Patent GB-190303876-A (GB)
Title: Improvements in Methods and Apparatus Employed in Wireless Signalling.
Inventor: FOREST LEE DE
Filed: 1903-02-18
Granted: 1904-05-18
Abstract: 3876. Forest, L. de. Feb. 18. Telegraphs.-Relates to means for protecting the receiving-instrument in wireless signalling- systems from interference either by periodic or a-periodic waves other than those to which the apparatus has been designed to respond. Fig. 1 shows a simple form of receiving-apparatus. The two collecting-antennµ A, A<1> are differently-tuned by means of coils C, and are connected to opposite ends of the wave-responsive device R. The telephone or other indicating instrument F is in the circuit of the local battery I, which also includes choking-coils K. A wave train corresponding in period with either antennµ causes a change of potential at one end of the wave-responsive device, and operates the indicating - instrument. An a-periodic wave train forces both systems A and A' to respond, but as the potential varies equally at both ends of the wave - responsive device, no signal is received. Fig. 2 shows a similar arrangement with transformers T, T<2> and T<1>, T<3> and with condensers U' to control the period and prevent shunting of the local receiving-circuit. One of the antennµ may be a-periodic, being connected directly to the wave-responsive device. In that case, the arrangement is sensitive to wave trains of one period only, but is still unaffected by a-periodic wave trains. Fig. 5 shows a resonant system of parallel or " Lecher # conductors crossed at x so that the antennµ A A<1> affect opposite ends of the wave-responsive device R, which thus fails to respond if both antennae are affected. When ground connection is dispensed with, a condenser of large capacity is connected to the base of the antenna, as indicated at e. Fig. 7 shows two distinct pairs of Lecher conductors, B, B' and B<2>, B<3>, of different period. The indicating-instrument F is differetntially wound, and responds when either R or R<1> is affected, but not for both. B', B' may be united into a common return wire. This differential principle is also applicable to the case when an a-periodic antenna is combined with one connected to a Lecher system. Fig. 10 shows a transmitting-device in which a-periodic oscillations are continuously sent from the antenna A and the key k controls the production of periodic oscillations in the antenna A'. P, P' are alternating generators, and S, S' are spark gaps. One antenna may be used for both sets of waves, both at the transmitting and receiving stations. In the form shown in Fig. 13, the telephone is placed across a bridge comprising resistances U, U' and wave-responsive devices R, R<1>. If both wave-responsive devices are affected, the balance is not disturbed. The Lecher systems B, B' and B', B<3> are of different lengths, and respond to waves of different frequency.

Abstract: 6093. Dysterud, E. March 16. Motors, gearing for.-Relates to a centrifugal clutch, specially for use with alternating-current electric motors, constructed to leave the motor free until full speed is attained, and then to come into action automatically. The rotary driving- part a, a' is loose on the driven shaft b, which carries a grooved disc c to engage segmental shoes d carried by lugs e<1> and faceplates e from the part a. Springs d<2> surrounding the stems d' of the shoes press the shoes normally away from the disc c. Levers pivoted between lugs e<2> of the faceplates have short arms f engaging the stems d' and long hollow arms f <1> drawn inwards by springs g and provided with mercury or balls h. In the position shown, the disc c is free to turn without the part a, and the weights h constantly change position in the arms ; at a certain speed, the balls move to the pivoted ends of the arms, and remain there until the arms have moved beyond the position parallel to the shaft, when they move to the free ends of the arms, and the shoes suddenly grip the disc, owing to the increased moment of the arms. The clutch may be brought into action by removing a restraining - load from the arms at a certain speed.

Granted: 1905-06-08
Abstract: 16,962. Harrop, F. T. Aug. 3. Beer and other beverages, raising and drawing-off.- In bar pumps, the spilt liquor is automatically and without delay returned to the pump cylinder with each delivery of fresh liquor. A cylindrical vessel e, preferably of glass, is connected to the drip-trough by a tube j, and is formed at its lower end with a boss l, to which is coupled an outlet pipe o leading to the pump cylinder. An india - rubber valve s, Fig. 3, which is a special feature of the invention, is stretched o v e the nipple r on the boss l. On the stem u, which passes through a guide v, are loosely mounted a float t and two valves, namely, the fibre or like disc w resting on concentric flanges z, and a conical metal piece y resting on a conical seating in the boss l. When the liquid from the drip-trough passes into the vessel e, the float t rises, opening the valves w, y and admitting the liquor so far as the valve s. On working the pump, however, the suction of the piston opens the flattened ends of the valve s, and the liquor passes into the pump cylinder, the non-return valve s closing immediately the piston has completed its up-stroke.
