Title: Improvements in the Production of Relief Pictures with the Aid of Photography.
Inventor: PIETZNER CARL
Filed: 1898-06-09
Granted: 1898-07-30
Abstract: 12,963. Pietzner, C. June 9. Ornamenting.-Relates to a process for producing relief pictures which may be used separately, or applied to decorate ceramic ware, glass, or metals. Glass plates are coated with a mixture of gelatine, isinglass, sugar, and acid chromate of potash. The film, when dry, is exposed under a photographic negative, and then allowed to soak for half to two hours in water. The gelatine swells in proportion as it has not been acted upon by light. If the relief is to be strengthened, a cast in wax or clay is taken, and this is pressed up from behind. Another cast is then taken from the retouched wax cast. A photographic print may be applied to the relief.

Granted: 1899-08-05
Abstract: 17,013. Walker, H. J. Aug. 6. Sparking and distortion of field, preventing; field magnets; frames.-For the purpose of preventing sparking at the collecting-brushes and distortion of the magnetic field by armature reaction, the field-magnet poles are made narrow and near together and, instead of being arranged parallel to the axis of the armature, they are inclined thereto so as to extend in a spiral or screw-like fashion partly round the same. With this arrangement, each armature coil at the moment of commutation will be partly under and be subject to the differential action of two adjacent and dissimilar fieldmagnet poles. Fig. 1 shows a four-pole machine so constructed. Each of the four magnets A, B, C, D is more or less U-shaped, and has two polepieces N S, N<1> S<1>, N<2> S<2>, or N<3> S<3>, inclined with reference to the armature axis, the adjacent polepieces of each pair of magnets being of the same sign. In the form shown, the pole-pieces Sand S<1> are cast in one with a yoke, the pole-pieces N and N', which are also cast in one, being secured to the yoke by bolts. The other half of the machine is similarly constructed. The coils F are placed on the cores formed by the adjacent pole-pieces N, N<1> and N', N<3>.

Title: Improvements in Electric Elevators.
Inventor: JOHNSON EDWARD HIBBERD
Filed: 1899-04-22
Granted: 1899-08-19
Abstract: 8498. Johnson, E. H., [Rennerfelt, G.]. April 22. Lifts, electrically actuated and controlled. Relates to apparatus for electrically controlling and regulating the working of a lift. The features of the invention are as follows:-(1) Auxiliary brake apparatus under the control of the attendant ; (2) speed-regulating apparatus which is thrown into action when the motor acts as a generator; (3) apparatus for preventing toosudden increase in the velocity of the cage ; and (4) electromagnetic means for automatically closing the field-magnet before the armature circuit. Fig. 4 shows an elevation of the arrangement to prevent excessive speed when the motor acts as a generator. The armature C in the circuit W<4> is polarized by a current which always passes through it in the same direction. The coil of the field magnet D is, with the starting-resistance F, in the armature circuit of the motor. When, therefore, the current in the field magnet D is reversed, it rotates the armature C and thus, by a crank b, link a, and pivoted arm a', bridges over the contacts E<2> and E<1> and short-circuits the resistance F. Excessive acceleration is prevented by the apparatus shown in section in Fig. 2. A pulley S driven from the motor is connected by a spiral spring u to a flywheel T on the same shaft. The pulley and flywheel have on opposed faces contacts P and R in the circuit w<7>, w<8> of an auxiliary electromagnetic brake. The inertia of the wheel T and the strength of the spring u are so adjusted that. when the acceleration of the pulley S becomes too great, the contacts P and R engage, thus putting on the brake and arresting the motion of the cage. The brake may also be operated by the attendant in the cage. The electromagnetic switch for the motor armature circuit is placed in the circuit of the field magnets, so that the latter is always closed first.
Patent GB-189911789-A (GB)
Title: Improvements in and relating to Targets and the like.
Inventor: PEIN EMIL FERDINAND GUSTAV
Filed: 1899-06-06
Granted: 1899-09-23
Abstract: 11,789. Pein, E. F. G. June 6. Targets. - The target is divided radially and concentrically into sections 1, which are attached to pins 2 arranged to slide through holes in a metal plate. When a section is struck, it is forced back against a spring 6, and the pin makes electric contact with an insulated metal contact - plate 3 and completes a circuit through a relay 7 and battery B'. An armature 9 of the relay is attracted, and completes a circuit through a contact-piece 10, a resistance coil 11, a battery B<2>, and an indicator A at the firing point. The strength of current through the galvanometer coils of the indicator depends on the resistance in the circuit, and varies for each target section circuit, so that the position of the pointer 22 on the dial denotes the number of the section struck. The wires for each quadrant of the target are coupled up to a line-wire, and indicator flaps 18, 20, 23, 24 operated by the currents through the line-wires show which quadrant of the target has been struck. Two galvanometer coils wound about needles on the pointer spindle in opposite directions are connected with the line-wires of the right and left halves of the target, and rotate the pointer to the right or left according to the half of the target struck. The armatures 9 are returned to their original position by a current from a battery B<3> passing through a key 25, line V, and coil 26. For a dummy figure target, the indicator dial may be divided to show the figure and the part of the figure struck. A dummy or figure of a man may be pasted in each quadrant of the target, and each quadrant may be divided along radial lines into sectors. The wires from the relays of the sectors are connected to contact-pieces carried by a bar which is moved to make connection with the resistance coils when the ordinary connections are broken.

Abstract: 12,635. Halsey, E. S. June 17. Quantity meters.-A motor meter, having a copper cylinder rotating in mercury, is constructed as shown in Fig. 2. The mercury receptacle 3 is moulded in non-conducting material, two narrow pole-pieces 4, 5 being embedded in it, and coated with insulating-material. The inner pole-piece 4 is made narrow at the top, and is secured on the lower limb S of a magnet 1. The outer polepiece 5 is made narrow at both its upper and lower ends, and secured to the other limb N of the magnet. The copper cylinder 2 is made about twice as long as its diameter, which may be 2“ inches, the thickness being 1/16 inch. It is carried by a spider 14 and nuts on the spindle 9, which also carries a circular weight 7 to balance its buoyancy. The current is led in by small copper pieces 22, near the end of the pole-piece 5. The weight 7 is movable, and can be screwed on the cover of the mercury receptacle 3, to close it during transport, by rubber packing 8. The armature may be shunted by a fixed resistance, and is also shunted by a loop of wire of high resistance, carrying an adjusting-slider, provided with a set-screw. The spindle 9 drives a wheel 10 on the axle of a pinion, which gears with another pinion, these separately driving two toothed wheels, loose on an axle. The axle carries a ratchet-wheel between the toothe wheels, and is connected to counting-gear ; the toothed wheels rotate oppositely, and carry pawls so that one drives the ratchet-wheel and counter forwardly, independently of the direction of rotation of the armature. The meter is stated to give not more than one per cent. inaccuracy in each direction, with 1/25 to full load. A modification with a disc armature is described, in which the magnet poles are both on one side of the disc, opposite an iron bar, and current is conducted in by small pieces at the centre and edge. The meter is mounted in a case shown in section in Fig. 5, the magnet, which carries the other parts, being secured by bolts 16 to the back board 17, which is stiffened by extended cross-pieces 18. The casing 29 overlaps the back, and is secured by a sliding-pin 21, which is perforated to receive a seal.
