Patent ES-372746-A1 (ES)
Title: A system for transporting passengers and/or freight, the system comprising transportation units of finite length moving on a way
IPC: B61B13/10
Filed: 1969-10-21
Abstract: In a railway system, goods and passengers are transferred, between express trains and feeder trains, while both are in motion, and the feeder trains are loaded or discharged at ordinary stations. Various elaborations of rail networks (Figs. 1-5, not shown) of increasing complexity are described in connection with moving transfer to yet faster non-stop trains. The transfer is effected by the interchange of receptacles 30-33, containing goods or passengers. In Fig. 6, semi-cylindrical receptacles 30, 31 have toothed rims 38, 36 enabling them to be swung about a vertical axis to effect interchange. In Fig. 7, the receptacles 32, 33 are moved across removable bridge elements 34 on wheels or rollers. The trains may be coupled together, during interchange of receptacles, by gripping magnets. In one form (Fig. 8, not shown) they may be steadied by an elevated guide rail 17. Reference has been directed by the Comptroller to Specification 1,166,109.

Title: Pusher assembly for freezers
IPC: F25D25/04
Filed: 1970-03-12
Abstract: Rows 20 of boxes are fed to a freezer by an endless conveyer belt 21 from which the boxes are transferred by a pusher assembly on to freezer plates 19. These plates are supported in a cradle (not shown) which moves vertically by increments until all the plates are filled. A belt conveyer is also provided at the rear of the freezer. Pusher assembly.-A pusher bar 44 is hinged to a pair of drive members 41 each comprising sections 49 hinged at 50. Chains 82 are secured to the sections 49 and are engaged by sprockets 88 driven by an hydraulic motor 90. The drive members 41 are guided in tracks 56 and the pusher assembly is adjustable vertically. By automatically controlling and reversing the drive from the motor 90, a row of boxes is pushed on to a freezing plate after which, on its return from a position B, the bar 44 moves over the boxes. A further row of boxes is moved into position by the conveyer 21 as the first row is being moved by the pusher. When defrosting, the automatic control for the motor 90 may be put out of action and, the pusher assembly having been lowered to permit the pusher to engage the adjacent plate 19, the pusher, under manual control, is caused to travel to position C. In a modification, Figs. 7, 8 (not shown), a pivoted pusher (107) is raised and lowered by a double-acting hydraulic cylinder (108).

Patent ES-420433-A1 (ES)
Title: Antiskid device for pressure-medium operated brakes
IPC: B60T8/38
Filed: 1973-11-10
Abstract: An antiskid device comprises an antiskid valve which in its braking position establishes a passage between the brake control line and the brake cylinder and in its skidding position establishes a passage between the brake cylinder and a pressure relief line. A valve responsive to skidding of the vehicle connects a control chamber in the antiskid valve to a source of pressure-medium in the braking position and to a pressure relief line when skidding occurs. A normally open monitor valve is in the pressure relief line and this valve is closed in response to a delay exceeding that of a normal skidding action. A throttle restriction bypassing the skid responsive valve supplies pressure-medium to the control chamber so that the antiskid valve can be returned to the braking position in the event that the skid responsive valve should for any reason remain in the skidding position.

Title: Arrangement for charging a furnace in a gastight and dust-tight manner
IPC: C10B31/04
Filed: 1977-02-09
Abstract: A furnace has a filling inlet normally closed by a removable cover. An arrangement is disclosed which opens the filling inlet, then fills the interior of the furnace, and then recloses the inlet all in gas-tight and dust-tight manner in order to prevent the free escape of dust and gases to the ambient atmosphere when the cover is removed from the filling inlet. The arrangement includes a housing surrounding the filling inlet and having a discharging port and a first opening separate from the discharging port, and a filling arrangement which is operative for conveying a charge from the discharging port through the interior of the housing and into the filling inlet when the latter is opened. A cover-extracting arrangement is operative for removing and subsequently repositioning the cover. The cover-extracting arrangement includes a hood which has a second opening and which is movable relative to the housing to and from a position in which both of said openings are juxtaposed in sealing relationship so that the interior of the hood can communicate with the interior of the housing. The cover-extracting arrangement also includes an electromagnet which is movable from the interior of the hood through the juxtaposed openings to the interior of the housing at a location adjacent the cover for engaging the latter. The electromagnet is operative for opening and subsequently reclosing the filling inlet. Thus, in accordance with the invention, any dust and gas escaping from the filling inlet towards the ambient atmosphere when the cover is removed from the filling inlet are confined within the respective interiors of the housing and the hood. Advantageously, the arrangement is used in conjunction with a battery of furnaces having respective filling inlets arranged in a row, and the cover-extracting arrangement, as a whole, is movable into sealing engagement with successive ones of the filling inlets for filling successive ones of the furnaces.
