Title: Apparatus for loading sacks arranged in layers
IPC: B65G57/112
Filed: 1978-01-17
Abstract: In a loading apparatus, sacks are moved from a supply source along a conveyor to a device which arranges the sacks into a layer. From this device, the layer of sacks is moved over a double conveyor belt structure to a member which loads the layer directly onto a loading surface or onto a previously deposited layer of sacks on the loading surface. To provide continuous operation of the apparatus even when a loading surface is being replaced, the different parts of the apparatus can operate at variable speeds. The double conveyor belt structure which normally moves continuously supplying layers to the loading member, switches to a step-wise movement and stores a number of layers of sacks until the loading surface is replaced and ready to be loaded.

Patent ES-8303624-A1 (ES)
Title: Fluid control system.
IPC: B62D5/09
Filed: 1982-03-12
Abstract: A system for controlling fluid flow from a source to a steering motor and one or more auxiliary motors comprises a priority valve and a steering controller. the priority valve has a housing that includes an inlet port connected to the source, a priority flow outlet port, an auxiliary flow outlet port, and a pilot port. A biasing spring urges the priority valve spool toward a priority position directing all flow from the inlet port to the priority port. The priority valve includes a pilot flow conduit directing a pilot flow of fluid through an orifice to the pilot port. Pressure upstream of the pilot flow orifice acts on the priority valve spool in opposition to the spring, and pressure downstream of the pilot flow orifice acts on the valve spool in addition to the spring. The steering controller has a load sense cavity communicating with a load sense port, and a neutral vent orifice which, when the steering controller is in neutral, communicates said load sense cavity with a return port for allowing a pilot flow of fluid from the pilot port of the priority valve to flow through said steering controller to the reservoir. Upon actuation from its neutral position, the steering controller substantially restricts flow through the neutral vent orifice to the reservoir before its main flow control orifice opens. As a result, pressure at the downstream side of the pilot flow orifice of the priority valve substantially increases before the main flow control orifice opens and assists the spring to quickly urge the priority valve spool to its priority position. When the main flow control orifice is open the load sense cavity of the controller is connected to the downstream side of the main flow control orifice so that pressures across the priority valve are varied with pressure variations across the main flow control orifice in accordance with operator demand and steering load.

Patent ES-8308272-A1 (ES)
Title: Hydraulic control device.
IPC: B62D5/09
Filed: 1982-09-13
Abstract: An improved hydraulic control valve is disclosed for providing the metering of fluid to a steering arrangement such as that normally employed on a motorized vehicle. The steering arrangement includes a piston-cylinder assembly, a main pump for supplying pressurized fluid from a fluid reservoir to the control valve and a control pump connected to the control valve which is actuated by a manually operated steering mechanism. The improved control valve includes a housing having an elongated bore formed therein. Movably positioned within the bore is a valve spool which has at least three annular grooves formed thereon separated by a pair of lands. The valve spool also contains a longitudinal bore formed therein which intersects a transverse bore which opens into the centrally positioned annular groove. The valve spool cooperates with the elongated bore to form control pressure chambers at each end thereof. Also positioned at each end of the valve spool are check valves which are closed when the valve spool is in a neutral position and which open when the valve spool is subjected to pressure loading. Fluid flow through the valve is directed by a plurality of passages formed in the housing. One of the passages connects the main pump to the elongated bore, while two working passages connect opposite ends of the piston-cylinder assembly to the elongated bore approximate the outer two annular grooves which are formed in the valve spool. There are also two control passages connecting the opposite ends of the control pump to the elongated bore approximate the pair of lands formed on the valve spool and at least one reservoir passage connecting the reservoir to the elongated bore approximately between an outer end of the valve spool and the outer annular groove formed thereon. This improved hydraulic control valve can be used for any constant pressure system.

Title: Unit connected to a tractor for raising and lowering an agricultural implement
IPC: A01B63/111
Filed: 1984-09-28
Abstract: A unit for raising and lowering an agricultural implement, which unit is connected to a tractor. The unit includes an attachment device (6) for attaching the implement to the tractor, a raising and lowering device (2, 5) for raising and lowering the implement, and a control and regulation device including a linkage and regulation device including a linkage system and an operating lever (27) disposed between the attachment device (6) and the raising and lowering device (2, 5).

The principal characteristic of the present invention lies in the fact that it includes a leverage mechanism (61 or 83) which is operable to act on the operating lever (27) for causing the operation of the raising and lowering device (2, 5) and the implement independently of the position of the control levers (36, 38) and independently of the deflection of the flexure bar (7). The leverage mechanism can cause complete raising of the implement and is operable to lower the implement back to the initial position set for the implement by the control levers.
Patent ES-8600468-A1 (ES)
Title: Proportioners.
IPC: F15B13/02
Filed: 1984-10-31
Abstract: Proportioners maybe used in hydraulic circuits to provide the symmetrical deployment of components controlled by these circuits. In the airbrake-deploying circuit of an aircraft, for example, certain fail-safe conditions must be satisfied i.e the symmetrical deployment of the airbraking surfaces, and therefore the inclusion of a proportioner is desirable if not essential. The invention described herein relates to a proportioner having twin fluid flow path which incorporates a stepper motor, the stepper motor being operable to adjust the flow in each flow path via throttling means so that the airbrakes, for example, are deployed synchronously. The proportioner is also inherently fail-safe, as the pressure differential in the two fluid flow path acts to cancel any imbalance which may be present in the hydraulic circuit should the stepper motor fail.
