Abstract: 169,706. Ammann, O. Feb. 25, 1918, [Convention date]. Gunnery calculators.-An appliance for plotting on a map certain gunnery information consists of a plate of transparent material capable of being pierced by a needle point and inscribed with representations of various trajectories a b c d. These are drawn upon a grid composed of range and contour height co-ordinates which are rectangular in the case of Fig. 1 and polar in Fig. 2. Curves such as f may also be imposed, joining points of the trajectories at which the projectile has the same time of flight or angle of impact &c. In using the device, it is placed upon the map with the origin A at the gun position and the points of intersection of a selected trajectory with the several contour lines are pricked through upon the corresponding map contours, thus delineating the area subject to fire with the particular gun elevation concerned. Similarly points may be determined upon the map at which the projectile has the same angle of impact, time of flight, &c.

Abstract: 158,081. Baumann, K., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 27, 1919. Ventilating dynamos etc.; inlet and outlet ports, arrangement of; air, cooling; valves and valve apparatus, actuating.-In a system for ventilating dynamos or other machines, inlet and outlet channels external to the machine communicate with an air inlet and an outlet in the machine, and have doors or shutters so arranged that the air may be caused to circulate in a closed circuit through the machine or, alternatively, freely through the machine through the inlet from atmosphere and through the outlet to atmosphere. The doors may be interlocked to ensure proper opening and closure. In the form shown in vertical and horizontal sections in Figs. 1 and 2 the machine 1 has air inlets 7, 8 and a central outlet 2 from which the air passes through a cooler 5 to a vestibule 6 which, by means of doors 20, 21, may be shut off from a passage 12 that leads to atmosphere at 13 and is closed by doors 22, 23. At the top and bottom of the vestibule are channels 9, 10 communicating respectively with the machine inlets 8, 7 and by openings 18, 19, which may contain grids, communicating also with the passage 12. The vestibule is flanked by lateral passages 14, 15 having ports to atmosphere 16, 17 closed by doors 24, 25. When the doors 22 to 25 are closed and doors 20, 21 open as shown, air circulates around a closed circuit comprising outlet 2, channel 3, cooler, vertibule, passage 12, openings 18, 19 and channels 9, 10 to the inlets 8, 7. When the doors 20, 21 are closed and doors 22 to 25. opened, free circulation occurs from atmosphere at 12 through openings 18, 19, inlets 8, 7, outlet channel 3, cooler, vestibule and passages 14, 15 to atmosphere at 16, 17. Interlocking means are described, consisting of pivoted levers and openings in and projections on the doors. Alternative arrangements are also described, employing hinged doors in place of sliding doors, as shown, and a vestibule which is permanently shut off from the passage 12. A thermometer in the air circuit may sound an alarm or a thermostat may be used to substitute free circulation for closed circulation automatically if the temperature reaches a predetermined limit.

Circulating or passing fluids through materials.-In apparatus for dyeing loose or spun fibres, woven fabrics, garments, &c., in which a number of dyeing-compartments communicate with a dye-reservoir and in which means are provided for forcing the liquor from the dye reservoir and returning it at will, swivel valve - members arranged between the reservoir and dye compartments are governed by stop-members to control the direction in which the liquor passes through the dyeing compartments irrespective of whether the liquor is leaving the reservoir or returning thereto. In the form shown in Fig. 1, the apparatus is divided by partitions a, b into a central liquor-reservoir g and two compartments c, d, each provided with a false bottom f. Swivel valve-members i, i<1>, carried by brackets, loose on shafts l, are arranged between the reservoir and the compartments, and are controlled by angularly disposed stopmembers p, p<1>, fast on the shafts l, which carry levers q, q<1> connected to a weighted link r. With the valves in the position shown, liquor forced from the reservoir passes into the compartment d, overflows into the compartment c, and, upon reduction of the pressure in the reservoir, returns to the reservoir past the valve i. The direction of flow can be reversed by turning the stop-members p, p', the weighted link r causing them to remain in the desired position. In a modification, the dyeing-vat comprises a reservoir g, Fig. 6, and a single adjacent compartment provided with a cage spaced from the bottom and two opposite sides of the compartment. End and central swivelvalves w, x are arranged to communicate between the bottom of the reservoir and the spaces between the cage and the bottom of the vat and between the cage and the sides of the vat respectively. The valves are loosely mounted on pins and are free to turn in a direction determined by stops z<1>, z<2> amounted on a hand controlled sliding shaft 2 and cooperating with extensions y on the valves.
