Title: Solar concentrator and energy collection system
IPC: F24S23/30
Filed: 1977-12-20
Abstract: A curved prismatic, Fresnel-type lens primarily used for concentrating sunlight in a solar energy collector. The lens comprises a substantially smooth, convex outer surface and a plurality of prisms arranged side-by-side along a curve on the inner surface to direct incoming light to a common area. Each of the individual prisms has a front and back face joined by a bottom face. The front and back faces of the prisms are oriented such that the angle of incidence of the incoming light with the front face is equal to the angle of incidence of the outgoing light with the back face. Further, each of the prisms is arranged along the curve such that they do not obstruct light passing through any adjacent prism. The bottom face of each prism is over-extended beyond the path of the light passing through the prism to prevent loss of light due to blockage by the bottom face or the rounded point between the back face and bottom face. The improved lens is used in combination with a solar energy collector comprising the improved concentrator and a suitable energy receiver for converting incident sunlight into a useful energy output.

Title: Self checking dynamic memory system
IPC: G11C29/42
Filed: 1979-05-25
Abstract: The storage space of the instant system is considered, for refresh purposes, to contain 512 groups of 26 bit digital words with each group containing 128 such words. Memory refresh is implemented by sequentially refreshing the groups of digital words at the rate of one group every 2.8 microseconds, giving an expected total memory refresh time of approximately 1.43 milliseconds. A particular digital word from each group of digital words refreshed is read from the memory and transmitted to a parity check circuit which generates fault signals for any digital word having faulty parity. At the end of each of the approximately 1.43 millisecond refresh cycles, the particular word read from each group refreshed is changed so that at the end of 128 full refresh cycles (approximately 184 milliseconds), the parity of every digital word in the memory has been checked. Further, circuitry is provided to store the location of the first failing digital word in a trap register in response to an indication of faulty parity.
Patent ES-482380-A1 (ES)
Title: Load responsive drum brake assembly
IPC: F16D65/09
Filed: 1979-07-10
Abstract: A vehicle drum brake has a shoe mounted on a back plate, one end of the shoe engaging an actuator and the other end engaging an abutment. To avoid the use of a fluid pressure control valve to vary the braking effort of the brake in dependence upon vehicle loading, the abutment is in the form of a roller which engages an arcuate member on the shoe, the roller being movable laterally of the shoe to vary the braking effort for a given actuating force. The roller may be connected to a pivoted lever which is rotatably mounted in the back plate and which is connected to a sprung part of the vehicle by a linkage. Movement of the sprung part due to changes in vehicle loading rotates the lever and moves the roller.
Patent ES-485224-A1 (ES)
Title: Vehicle brakes with automatic slack adjusters
IPC: H02H3/00
Filed: 1979-10-19
Abstract: In brakes in which a friction member is urged into engagement with a rotatable braking member by a fluid-pressure operated actuator, for example internal shoe-drum brakes, the actuator and an adjuster for adjusting brake clearances are located between different pairs of shoe-ends. If the adjuster is automatic, it is difficult to transfer signals at the actuator that adjustment is required to the adjuster with sufficient energy to operate it, without affecting the operation of the actuator. Thus the adjuster is operated by a supply of pressure fluid controlled by a valve assembly which is operative to supply fluid to the adjuster when relative movement between parts of the actuator exceeds a predetermined value. The adjuster is operated by a slave unit. The valve assembly may comprise a valve operated by rotation of a shaft for applying the brake, or two valves embodied in the actuator itself.
