Granted: 1905-04-27
Abstract: 4632. Boult, A. J., [Beck, H. M., and Smith E. W.]. March 6. Specific-gravity estimating-apparalus.- Relates to hydrometers with temperature-compensating devices, adapted to give a constant reading notwithstanding changes of temperature of the fluid under examination, and applicable for measuring the changes of density, other than those due to changes of temperature, in the electrolyte of a storage battery, and also to means for recording such changes of density. Fig. 1 shows a hydrometer 1 containing oil or other temperaturecompensating substance a and having an opening at 2 for the passage of the liquid tested. The tubular part, having the opening 2, may extend into the oil chamber, which may also contain part of the liquid to be tested. Fig. 3 shows an air chamber 6, a weighted part 7, a graduated stem 8, and a bent tube 9 through which the electrolyte or the like passes to the chamber a containing the temperature-compensating liquid. Fig. 4 shows a bent tube 11 sealed at the upper end to form an air chamber. Fig. 6 shows an expansible hydrometer with a flexible wall 14. This form may have an air chamber 6 and may be weighted with shot 16. Fig. 7 shows a similar hydrometer with compound convex expansible wall x, while Fig. 8 shows one with corrugated walls y. Fig. 11 shows a scale 20, supported in the stem 8 by a spring 18, the length of which changes with the temperature. Fig. 12 shows a hydrometer 3 connected to a balance lever 21 carrying a pencil or stylus 22 which marks a record on paper on a drum 23, operated by clock-work.

Granted: 1906-05-16
Abstract: 10,299. Boucherot, P. M. J., [trading as Soc. Boucherot & Cie]. May 17, 1904, [date applied for under Patents Act, 1901]. Electric railways.-The reciprocating motion of an electromotor for mountain railways and slow locomotion in general, having its vibrating parts excited by continuous currents and the stationary parts excited by alternating currents, may be converted into continuous rectilinear movements by the employment of friction ratchets which act directly upon the rails of the track or upon a rail specially provided for the purpose. One arrangement of such ratchets is shown in Fig. 5. The periodical adhesion of the members 12 to the rail is obtained by the downward pressure of the levers 13 which are connected to the transmission rods 16 of the reciprocating cores through springs 14 secured to masses 15. The movements of the left-hand ratchet are symmetrical with those of the right-hand member, so that the centre of gravity does not vary. The clutches are reversible and permit of electrical braking and the recuperation of energy in descending inclines.

Title: Improvements in and relating to Controlling Devices for Electric Motors.
Filed: 1906-01-10
Granted: 1907-01-10
Abstract: 725. British Thomson-Houston Co., and Sugden, J. Jan. 10. Switches.-In controlling motors by varying resistance in the field, means are provided for shortcircuiting the resistances when the circuit is opened, so that a full field is obtained at starting. The regulating-resistance e, in series with the field f, is short-circuited when the field is de-energized, by a piece l on the armature k of an electro-magnet h, the latter being in series with the field, resistance e, and a hold-on magnet d. On failure of the current in the field circuit, the whole of whatever resistance is in series at e is short-circuited between studs m by the piece l, which is dropped as the magnet h is de-energized. The armature is re-set by the rotary arm engaging a projection n when returned to cut out all resistance.

Title: A Potential Regulator for Electric Currents
Inventor: WARMING KAI
Filed: 1906-01-30
Granted: 1906-11-01
Abstract: 2337. Warming, K. June 14, 1905, [date applied for under Patents Act, 1901]. Fluid governors for electromotors. The alteration of shape of mercury contained in a rotating vessel driven from the shaft is caused to vary resistance in the circuit, thus regulating the speed. In the form shown in Fig. 1, a box 1 containing the mercury is fixed to the vertical shaft 2 and to a set of contact-cylinders 3, 4, 5, 6 of different heights insulated from one another and from the shaft by cylinders 16. The upper edges of the cylinders . may be prolonged by metal gauze in order to increase the surface of contact. Brushes connected to rheostat sections bear on the outside portions of the cylinders and shaft, and the box itself, provided with a slip-ring 7, forms the opposite line terminal. When the apparatus is at rest, all the cylinders are short-circuited and current passes directly through the shaft 2 from one side of the line 8 to the other side 13, resistance being gradually introduced as the mercury assumes its figure of rotation.. The circuit is interrupted when the mercury leaves the cylinder 6. In the form shown in Fig. 2, a set of gauze cylinders 3 ... 7 is secured by an insulating-block 16<1> to a fixed but vertically adjustable rod 17, by moving which the regulating action can be varied. The joint at the lid 15 may be closed by a mercury seal, which may be used to leld the current to the box 1, thus dispensing altogether with brush contacts.
