Patent ES-471570-A1 (ES)
Title: Fluid-pressure operated anti-skid braking system for vehicles
IPC: B60T8/40
Filed: 1978-07-07
Abstract: In a fluid-pressure operated anti-skid braking system operation of a brake-applying relay valve is controlled by control pressure in an application chamber. A memory chamber is connected to the application chamber through a one-way valve and an orifice permits pressure in the memory chamber to decay into the application chamber when the pressure in the application chamber reduces. Re-application of the brakes following a skid is controlled by closure of a latch valve which permits only a restricted flow of control pressure into the application chamber. This is sufficient to re-apply the brakes rapidly in a first stage until the pressure in the application chamber becomes equal to that of the decayed pressure in the memory chamber, whereafter brake re-application continues at a slower rate since the restricted flow of control pressure has also to increase the pressure in the memory chamber.

Title: Method of, and circuit for, controlling the detenting of multiphase stepper motors.
IPC: H02P8/32
Filed: 1980-07-15
Abstract: A damping control system for a three phase stepper motor. A reluctance velocity transducer is used for each of the three phases. The output of each of the transducers is proportional to the rotational velocity of the motor. Each of the transducers is rotationally phase shifted 3.75 with respect to one another and phased to the motor rotor rotationally such that the zero voltage crossings of the transducers correspond to the zero torque crossings of the motor. During damping or detenting of the motor the selected phase has current applied to it which is equal to a predetermined fixed value plus the feedback from its associated transducer. The windings on each side of the detent position have current applied to them which is proportional to the voltage from their respective feedback transducers. The voltage in each of the windings is amplified by a selected gain constant. The current in each of the windings is such that maximum torque is applied to drive the motor to the detent position with appropriate current reversals in the windings to damp out any kinetic energy in the rotor during detenting.

Title: Sinker for knitting machines for producing a knitted plush fabric
IPC: D04B9/12
Filed: 1980-08-28
Abstract: A known sinker for use in knitting plush fabrics was expensive to manufacture in view of the complexity of its shape and did not admit of adjustment of the relative length of the loops of the plush and ground fabrics. In order to overcome this a sinker is formed of two separate relatively slidable parts 54 and 56 independently operable by means of cutouts 58 and 60 (or butts) cooperating with sinker cams 42 and 44. The upper part 54 has a tongue 76 extending forwardly from a knitting surface 72 and a draw edge 66 for the plush loops while the lower part 56 has a tongue 78 extending forwardly from a draw edge 70 for the ground loops. In a variation the tongue 78 with knitting surface 74 is omitted so that a part of the needle cylinder acts as a knitting surface. In this case the draw edge is formed as a notch.
