Patent GB-190306741-A (GB)
Title: Improvements in Telephonic Exchanges.
Filed: 1903-03-23
Granted: 1903-06-04
Abstract: 6741. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. March 23. Telephone systems.-In a system including a central exchange and branch exchanges, polarization cells or condensers are used at the branches to stop current from a central signal battery, and connections are made as shown in Fig. 1 to enable a closing signal to be produced automatically at the central exchange, when a connected subscriber hangs his receiver on the telephone switch or when the branch exchange removes a connected plug. According to a second part of the invention, the subscribers' transmitters are supplied with current from a common battery at an exchange, as shown in Fig. 3. Fig. 1 represents the connections at a branch exchange to the lines of two subscribers 1, 2 and the lines b, d of the central exchange. Polarization cells are used in the subscribers' instruments as described in Specification No. 9999, A.D. 1899. The lines b, d are connected at the central exchange to a closing signal and a battery. The branch exchange has indicators a, 1, 2, normally connected to the circuits by the jack springs. A polarization cell or condenser f is connected in series with the indicator electromagnet e, between the central-exchange wires b, d, with an intermediate connection to the springs, by which the cell f is normally short-circuited so that the central exchange can call the branch. When a plug is inserted to connect the central exchange, the cell stops passage of current from the central battery through the electromagnet e, while the inductance of this prevents short-circuiting of speaking currents. In a modification, Fig. 2, the polarization cell or condenser m is placed in the central-exchange line b ; when a plug is inserted in the jack l, the cell is connected parallel to the electromagnet e, to carry the speaking currents. In the common battery system shown in Fig. 3, each indicator a at the exchange has a laminated iron core carrying two highly-inductive coils, connected separately between the battery c and the line-wires through an inquiry jack q and a connecting-jack t. When any call is received, the corresponding indicator flap makes contact at n to close the circuit of a call bell v. A telephone i is then connected by a plug to the inquiry springs q, which disconnect the battery c. When two subscribers' circuits are connected, one plug is inserted in a jack q and the other in a jack t, the battery c being thus connected to the circuit at one place. One pole of the battery is earthed. The electromagnets a are polarized, or their action is controlled by springs or weights, in order that the current from the battery c may not operate them. The electromagnets a act as choking-coils to prevent passage of the speaking currents through the common battery connections.

The piston g may be actuated by air pressure, electrically, or by a rack and pinion.
Patent GB-190318720-A (GB)
Title: Improvements in Axis Finders for Lenses
Inventor: BOULT ALFRED JULIUS
Filed: 1903-08-31
Granted: 1903-10-29
Abstract: 18,720. Boult, A. J., [Mincer, L. L.]. Aug. 31. Lenses.-Relates to apparatus for determining the positions of the axes of cylindrical lenses. The lens is placed in a holder, and a mark made on it; it is turned in its own vertical plane until crossed lines on a card appear without distortion. The angle of tilting is read on a dial attached to the holder, the pointer being kept vertical by a plumbbob. This gives the position of the axis relative to the mark on the lens. The dial forms the front of a case 3, Fig. 2, the centres of the dial and of the back of the case forming bearings for the pivot of the pointer. This case 3 is fitted in an outer one 2 which is closed by a flat glass plate 6. To one side of the outer case is fitted a lens holder 23, 25, of which the part 23 has a narrow radial slot x, Fig. 1. In the same part of the outer case is a narrow slit 4<a> forming a pocket into which may be thrust the tongue 19 of a spectacle-frame holder 20, 21, or the tongue 27 of an auxiliary lens holder 22. The pointer may be arrested temporarily by a lever 13, Fig. 5, or other arrangement. For piano-cylindrical lenses, a mark is made on the lens, which mark is fitted into the slot x. The case is tilted (and with it the lens) till the image of crossed lines on a card can be seen without distortion. The angle the pointer makes with the vertical is then read ; or the pointer may be held by the lever 13, and the angle read subsequently. Thence the axis of the lens is known. For a sphero-cylindrical lens, the effect of the spherical surface is counteracted by a suitable spherical lens placed in the holder 22.

Nov. 4 D r i v i n g-mechanism ; treadle-levers. - In driving - mechanism for bicycles &c., an up-andd o w n motion of the pedals E through a limited arc imparts a continuous rotary motion to the road wheel by means of crank levers C, D, rods F, and cranks G. The cranks G are arranged in opposite directions while the pedal cranks are mounted upon a spindle B in such a manner that, when one pedal is at the top of its stroke, the other is at the bottom. Clutch mechanism may be interposed between the cranks G and the road wheel ; this mechanism preferably comprises rollers J adapted to engage discs H, so that, when pressure is applied to the pedal, the corresponding rollers engage the disc, and, when the pressure is released, a rubber pad disengages the rollers and the wheel runs free ; when pressure is applied and the pedals are held stationary, the rollers act as a brake. To avoid dead points, the rollers may be caused to move to and fro through a limited arc on the disc ; in this case the pedal cranks may be connected by bevel gearing, as shown in Fig. 3, or they may engage slotted blocks which move in guides and are connected to the levers I carrying the rollers. The joints between the levers and cranks are preferably loose and furnished with a spring or rubber cushion. Stops or the like L, Fig. 3, may regulate the up-anddown travel of the pedals.

Title: An Automatic Smoke Indicator or Recorder.
Inventor: GOODMAN JOHN
Filed: 1904-06-06
Granted: 1905-04-06
Abstract: 12,726. Goodman, J. June 6. Smoke indicators.- Relates to apparatus for continuously and automatically indicating the amount of smoke emitted from a fire &c. This is effected by withdrawing some of the smoke-laden air and filtering it by means of a travelling tape, the deposit on which gives the required indication. The apparatus comprises an outer tube a, Fig. 1, and an inner concentric tube j, each of which is closed at its inner end, which is placed in the path of the smoke. A tape g<1>, drawn by clockwork from a roll g, mounted upon a box d, passes down the tube a and around a cylinder k on the end of the tube j, and is finally wound upon a drum f. The outer end of the inner tube is connected to a water or steam injector, which draws the smoke through slits o, m in the tubes a,j, and out by the inner tube. The tape g, which thus acts as a filter and becomes blackened by soot or smoke, may be marked off in lengths of an hour's travel to facilitate comparison with tapes previously blackened by smoke for use as standards. In a modification, the outer tube is dispensed with, and the cylinder with the slit is placed at the opposite end of the inner tube. According to the Provisional Specification, the drum or barrel may be perforated or formed as a screen all round, and the suction tube may be connected axially to the interior of it, in which case the drum may be arranged to run loose in bearings to decrease friction. Where great accuracy is not required, the tape may be made of material impervious to air, and passed around a solid drum or barrel, with or without any device for causing a suction through the slit in the enclosing pipe or tube.
