Title: Improved air-conditioning arrangement with automatic regulation, particularly for ships, aircraft, vehicles and the like

Abstract: 665,637. Ventilation. SOC. ANON. DES ETABLISSEMENTS NEU, and DENIS, L. Feb. 28, 1949 [May 19, 1948], No. 5450/49. Addition to 638,030. Class 137 The air conditioning system according to the parent Specification is modified in that the two air compressors can be connected either in series, to obtain the necessary degree of cooling under summer conditions or in parallel, to cater for winter conditions, when the whole of the ventilation air passes through the compressors and is warmed as required by supplying warm instead of cold water to the coolers. Fig. 1 shows the plant set for summer conditions. Air enters the inlet 2 and passes to a compressor 5 which forces it through a cooler 7 where some of its moisture condenses. It then passes into a second compressor 1 which forces it through a second cooler 8, wherein more moisture is deposited, and into a turbine expander 6, which drives the compressor 5 and serves to expand and cool the air, which then passes into a balancer chamber 9. The pressure in this chamber, as determined by the demand of the system for air, controls the speed of compressor 1 through a manostat 10 and throttle valve 4. The cold, dry air from chamber 9 is led to each compartment served, to be mixed with recirculated or " outside " air delivered by a fan 13, the mixing being varied by a valve 24 controlled by a thermostat 25. The air humidity is then adjusted in a chamber 31, the amcunt of moisture added being controlled by a humidostat 33 operating a valve 35. Under winter conditions the fan 13 is shut off and the compressors connected in parallel by turning valves 43 and 45 through 90 degrees as indicated, warm water then being supplied to the coolers 7 and 8.

Abstract: 1,248,894. Supporting sliver cans. DAIWA BOSEKI K.K. and HARA SHOKKI SEISAKUSHO K.K. 5 Feb., 1970 [10 Feb., 1969], No. 5673/70. Heading D1F. A device for supporting a sliver can comprises a can mounting dish 1, a compressible spring 8 to support the sliver receiving plate 10, a face formed on the can mounting dish for engagement with a sliver can 6, a sensing element 15 associated with the can mounting face to sense the presence or absence of a can on said face and means responsive to the actuation of the sensing means 15 for anchoring the spring 8 received within the can mounting dish 1 under compression when a can is absent from the mounting face and for releasing the spring 8 to urge the sliver receiving plate 10 upwardly within the can 6 when a can is present on the mounting face. In operation when a can 6 is present on the mounting face the sensing element 15 is depressed and -pivots a lever 16 about a fulcrum 17. The other end of the lever 16 is connected to a lever 18 which via a leaf spring 21 is connected to a further lever 19 passing through a hole 20 in a central boss 4 formed in the mounting dish 1. When the element 15 is depressed, the levers 18 and 19 are moved towards the: right, and the spring 8 is released so that a bearing plate 9 pushes the sliver receiving plate 10 upwards within the can 6. As sliver 14 is deposited in the can, the plate 10 is pushed down compressing the spring 8. As the spring 8 is fully compressed a boss 12 on the underside of bearing plate 9 enters a recess 11 in the central boss 4. On removal of the can- 6, the element 15 is free to move upwards and the force of - the leaf spring 21 urges the lever 19 to the left and the end engages in a recess 13 on the boss 12 to retain the spring in the compressed condition until a can is again placed on the can mounting face of the dish 1.

Abstract: 365,840. Clocks. SOC. ANON. LES FILS DE L. BRAUNSCHWEIG FABRIQUE ELECTION, La Chaux-de-Fonds, Switzerland. Feb. 24, 1931, No. 5796. Convention date, Feb. 28, 1930. [Class 139.] Driving mechanism.- In a driving device for clocks, counters, indicators and the like, which includes a periodically wound maintaining spring, an eccentric on a member driven by the spring periodically releases a detent lever plate, articulated to a driving wheel, from engagement with a fixed stop, whereupon the driving means advances the detent to the next stop, simultaneously winding the maintaining spring. The driving pinion b is mounted on a spindle a carrying a plate c bearing an eccentric pin d. The spiral spring f is attached at one end to the pin d and at the other end to a bush e<1> freely mounted on the spindle a and carrying integral therewith a toothed wheel e, forming the driven member, and an eccentric member n which rotates in a slot cut in a plate lever g, pivoted at d and provided with a projection h adapted to engage, detent-like, with stops i. In Fig. 2, the driving member is shown locked by the projection h abutting against a stop i, the initially energized spring f providing the force necessary to operate the driven member e, the speed of which is controlled by the escapement connected thereto. As the bush e<1> rotates, the eccentric member n rotates the lever g about its pivot d, and, after a predetermined time, the projection h escapes past the stop i, when the plate c, under the action of the driving force of pinion b, rotates suddenly to the next stop i where the plate lever g is again held, the spring f being simultaneously re-energized. The pin d is extended to pass through an arcuate slot in the wheel e to limit the unwinding of the spring f if there is no driving force.

Abstract: 322,701. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 22, 1929. Addition to 307,529. Hydrogen.-The process of the parent Specification is modified by the replacement of part of the air used in the production of a hydrogennitrogen mixture for ammonia synthesis by carbon dioxide, which may be that obtained from the gas mixture resulting from the electric arc treatment. A mixture in the correct proportions for the synthesis can thus be obtained. In an example, a mixture of 1.8 cu. m. of methane, 2.8 cu. m. of air and 0.8 cu. m. of carbon dioxide is treated in an electric arc operating with a current of 2.6 amps. and 1400 volts. The gas mixture obtained is treated with steam in the presence of nickel to convert the carbon monoxide into carbon dioxide which is then removed by absorption, giving a hydrogen-nitrogen mixture in the ratio of 3 :1. A part of the carbon dioxide separated is again exposed to treatment in the arc in admixture with further air and methane.
