Patent ES-373203-A1 (ES)
Title: Central heating and cooling system
IPC: F24F3/06
Filed: 1969-11-05
Abstract: A central heating and cooling system comprising two independent circuits of the singe-tube type, a cold circuit which is coupled with its outgoing and return lines to a central cold-production machine and a hot circuit, also with outgoing and return lines coupled to a boiler or boilers, or alternatively to an exchanger or exchangers. These circuits comprise as many branch conduit lines as there are levels or stages in which the utilization points are located, each utilization point comprising a water-air temperature-exchange unit having a single air circuit. Each branch line has a pump upstream of its exchanger and a nonreturn valve downstream of its exchanger, flow through the branch line being from a first point on the associated main conduit to a second point on the associated main conduit, the first point being downstream of the second point with respect to flow of the heat exchange fluid through the main conduit. In this way the flow of the fluid through the branch line is prevented when the associated pump is not in operation.

Title: Screening process
IPC: B07B1/28
Filed: 1970-04-11
Abstract: A method of screening dry or moist granular or powdery material consists in feeding the material on to the surface of a vibratory screen and causing the depth of the bed of material on the screening surface to increase or to remain constant as the material progresses from the feed end to the discharge end of the screen. It is stated that by this method the average throughput of the undersize particles through the screen is more than double that obtained by known processes thereby considerably reducing the amount of under - size particles entrained in the oversize particles. Formulae are given for calculating what speed the material should have at different points along the screen for the depth of the material to increase or remain constant. In one form of apparatus. Fig. 5, the screen surface is subdivided along its length into sections 1-10 having inclinations relative to the horizontal decreasing from 35 at the feed end to 0 and increasing to 5 at the discharge end. Mechanisms 21-30 mounted on the frames of the screen sections impart independent and different rectilinear or elliptical vibratory movements to the sections. The material to be screened is fed from a conveyor 41, the undersize falls down chutes 31-40 onto a conveyor 42 and the oversize, with some entrained undersize, falls on to a conveyor 43. Dimensions are given.

Patent ES-458944-A1 (ES)
Title: Wheel slip control system adapted to use on low coefficient surfaces
IPC: B60T8/72
Filed: 1977-05-19
Abstract: A wheel slip control system generates one level of brake relief when a fixed threshold of wheel deceleration is exceeded. The system generates a second level of brake relief when a variable threshold, dependent upon both deceleration and velocity, is exceeded. A fixed acceleration threshold circuit monitors wheel acceleration during brake relief. Under normal road and load conditions, where wheel acceleration is great enough to exceed the fixed acceleration threshold, termination of brake relief is initiated by the increase in wheel velocity past a variable reference threshold which has a fixed part and a variable part. The fixed part is an a priori prediction of the minimum vehicle velocity decrease under normal stopping conditions. The variable part is dependent on wheel acceleration alone. When the acceleration threshold is not exceeded, as with slippery roads or very light loads, termination of brake relief is delayed until wheel acceleration decreases to a low value. This allows the wheel velocity to come up to approximately full vehicle speed before allowing brake re-application. A brief re-energization of the first level of brake relief, performed after a brief delay, reduces the tendency of the vehicle wheels to hop and bounce.
