Patent ES-366707-A1 (ES)
Title: Steering equipment particularly for heavy vehicles
IPC: B62D5/097
Filed: 1969-05-02
Abstract: Hydrostatic steering mechanism comprises a steering motor 2 which is part of a secondary hydrostatic system including a control unit 13 actuated by the motor 6 of a primary system having a control unit 5 actuated by a steering wheel 1. Each control unit 5, 13 includes a control valve and a metering device. The motor 6 may be a rotary motor and the systems preferably incorporate step-up means which increase the amount of fluid passed to the steering motor 2 for each revolution of the steering wheel 1. Such means may be an hydraulic amplifier in the primary hydrostatic system or a mechanical step-up gear on the input side of the metering device of the secondary control unit 13. The metering device of the secondary control unit 13 may be an orbital gear pump having a displacement per revolution equal to the total volume of the displacement chambers therein multiplied by the number of gear teeth, or the metering devices in both control units 5, 13 may be rotary piston pumps with volume step-up means. Separate feed pumps 4, 14 feed the two hydrostatic systems from a common reservoir 21. One-way valves 24, 25 connect the first system to the second so that the steering motor 2 can be operated from the primary control unit 5 should the feed pump 14 be inoperative, a oneway valve 26 preventing reverse flow through the inoperative pump. If the feed pump 4 is inoperative the motor 6 is operable by manual actuation of the metering device in the primary control unit 5. Fig. 2 shows a unitary assembly 20 incorporating the primary motor 6 and the secondary control unit 13. The motor 6 comprises a rotatable eccentric ring gear 29 and a gear 28 mounted on a shaft 27. The metering device of the control unit 13 comprises an orbital gear 38 and a fixed gear ring 40, and the control valve comprises inner and outer rotatable valve sleeves 45, 46. The inner valve sleeve 46 is coupled to the shaft 27 by a pin 47, and the outer valve sleeve 45 drives the orbital gear 38 through a pin 48 and a wobble shaft 49. The-pin 48 engages a larger bore 51 in the inner valve sleeve 46 so that the sleeves are coupled with provision for limited relative rotation, and spring means 50 urge the sleeves into a predetermined neutral position. Ports 57, 58 in the outer valve sleeve 45 co-operate with grooves 63, 64 in the inner valve sleeve 46 to control fluid flow to the steering motor 2, and bores 59 in the outer valve sleeve 45 co-operate with grooves 65 in the inner sleeve 46 to circulate the fluid in the appropriate direction through the metering device 38, 39.

Title: Hydroponic system.
IPC: A01G31/02
Filed: 1982-01-29
Abstract: In order to be able to utilize a hydroponic system in the best possible way and at the same time to secure the best possible growing conditions for the plants, including especially the supply of oxygen to the roots in the simplest possible way, the system is built up by means of a plurality of fluid containers (1) with an overflow (2 or 17) and with an upper section (3). In this upper section (3) a nutrient substrate (4) e.g. consisting of foam can be mounted e.g. in a way to permit the formation of an air space (5) between the substrate (4) and the fluid (15). The fluid is led to the container by means of a tube (6) ending at the bottom. This secures the supply of nutrient and oxygen to the roots. To secure the outlet from the container a tube (8 or 9) is arranged that is supplied with apertures (10) at the top at an equal distance to each other. Accordingly, arches (7) with projections (11) are provided in the bottom, so that the container can be 'locked' firmly to the tubes. One of the tubes (8, or 9) may further act as a drain for the fluid, which can drip from the container down into the apertures (10) of the tube, either through an external overflow (2) or through an internal overflow (16), ending in a tube stub (17) at the bottom of the container.
Patent ES-8305481-A1 (ES)
Title: Fluidized bed heat exchanger with control to respond to changes in demand
IPC: F23N1/08
Filed: 1982-04-08
Abstract: In a fluidized boiler system, the rate of fuel flow and bed depth are simultaneously controlled in response to variations in a load demand signal representing the need for steam output from the system. When the load demand changes, the rate of fuel flow is varied accordingly to provide a change in the bed temperature to thus provide a rapid response to the change in the demand signal. At the same time, the system changes the rate of flow of limestone to the bed and the rate of removal of spent particulate material of the bed to change the bed depth to respond more slowly to the change in the demand signal. As the depth of the fluidized bed approaches a value corresponding to the demand signal, the temperature of the bed will change back toward a median value.
