IPC: B61D27/00
Filed: 1967-11-15
Abstract: In an air conditioning system for railway vehicles in. which cooling air is supplied to the compartment and which is adequate to cool a full compartment, the cooling capacity is reduced dependent upon the temperature in the compartment when there are fewer passengers. The cooling is reduced by regulating the heat supply over at least part of the range and by regulating the basic amount of cooling air supplied over at least part of the range. It is preferred to reduce the cooling air and to increase the warm air simultaneously but these changes could take place in sequence. This method ensures that the basic air supplied per person is maintained constant. Apparatus conditioning the air comprises an intake 4 for fresh air, an intake 5 for recirculated air, a filter 7, cooling coils 9, 10, and heating coils 11, 12. A blower 1 delivers the air to a channel 22 and to a second channel 23 channel 22 controlled by a device 44 on the vehicle roof and sensitive to weather conditions supplies the basic amount of cooling air, channel 23 includes a heater 24 controlled by heating and cooling thermostats 25, 26 and supplying warm air at 80 or 50 C., respectively. A safety thermostat 27 is provided and operates if a predetermined temperature is exceeded. A mixture of air from ducts 22, 23 is admitted to the compartment via outlets 33 situated under a window and controlled by a perforated slide. The slide is connected to a rotating slide valve 35 in the duct 23 so that as one valve is opened the other is closed, and vice versa. Further openings 39 from the duct 22 are provided beneath the seats. Air from the compartment is drawn into a housing 28 above the outlets 33 and below the outlets 30. A valve 41 admits air to a corridor heater 40 and a further valve 43 supplies air to a washing space or store room. The cooling system comprises two coils 9, 10 selectively controlled by magnetic valves 18 and having a valve 17 by which both coils can be switched off. A thermostat 19 controls the temperature in the cooling portion of the air conditioning unit 8. The system also includes the usual motor 14, compressor 13, condenser 15 with fan, and a collecting flask 16 for the cold medium.

Patent ES-428231-A1 (ES)
Title: Reversing valve operated by a pilot valve
IPC: F15B13/04
Filed: 1974-07-12
Abstract: A reversing slide valve for a hydraulic motor is operated by a pilot slide in a common valve body with the main slide, the latter being biased toward an intermediate position by springs and entraining the pilot slide when moving from the intermediate to either terminal position. Friction rings prevent movement of the pilot slide with the main slide when the latter returns to its normal intermediate position under spring bias. The pilot slide directs pressure fluid to compartments in the valve body partly bounded by end faces of the main slide in such a manner that the main slide is moved from its intermediate position into the terminal position remote from the last-occupied terminal position whenever pressure fluid is supplied to the valve after an interruption of fluid supply.

Title: Run-away preventing device for skis
IPC: A63C7/10
Filed: 1975-07-23
Abstract: Run-away preventing device for skis. A pair of prongs are pivotally mounted at each side of a ski for alternately occupying an inactive position alongside of and parallel with the ski or an active position projecting downwardly from the ski. A generally U-shaped member is connected to said prongs and lies against the upper surface of the ski and under the ski boot when the latter is in position on the ski. Said U-shaped member is so arranged as to be subjected to tension when pressed down against the ski by the ski boot with such tension being relieved when same is permitted by removal of the ski boot to spring up away from the ski and move said prongs into the above-mentioned active position. Said generally U-shaped member and the prongs connected thereto comprise only a single movable part and hence combine a minimum of parts with a maximum of reliability.

Title: Selective plating on non-metallic surfaces
IPC: H05K3/18
Filed: 1975-09-22
Abstract: An aqueous method for the selective metallization of a non-conductive surface with nickel, copper, cobalt, or gold, a thin film of palladium dichloride is applied to a film after stannous chloride, a chelating agent and a dye operative as a catalyzing promoter active to a light between 4,500 A and 6,000 A or broadly 3,750 to 8,000 A are applied to the surface of a non-conductive material and that thin film is exposed in selected areas to light through a photographic negative to a light of a wave length determined by the dye. The thin film of the palladium salt, catalytic to the deposition of nickel, copper, cobalt, or gold from an electroless bath thereof causes selective deposition when the thus treated non-conductive material is then immersed in an electroless bath to metallize the areas which have been rendered catalytic by the action of dye and chelating agent in combination with the palladium salt. The preferred dye is Erythrosin dye and the chelating agent is orthopenanthroline.
