Patent ES-341557-A1 (ES)
Title: Wheel brake cylinder with self-adjusting mechanism
IPC: F16D65/54
Filed: 1967-06-08
Abstract: An automatic lining wear adjuster, in a fluid pressure operated brake actuating cylinder, having pistons 7, 8 (Fig. 1) movable apart to apply the brake by fluid pressure in a working chamber 6, comprises a rod 9, 10 having circumferential grooves for engagement with resilient rings 11, 12. The rings latch by their own resilience into a respective groove. When the pistons have been moved in a brake applying direction a distance corresponding to the normal brake clearance piston surfaces 13, 14 will have just reached the rings 11, 12. If lining wear is sufficient the pistons will continue to move pushing the rings so that they expand over the bumps into the next successive grooves. During the return movement of the pistons a stepped portion or groove in piston plates 4 and 5 (see Fig. 2) encompasses the respective rings preventing them from expanding radially and hence the rings remain in the grooves into which they were pushed and act as a piston stop. Thereby the lining wear has been accommodated. In an alternative embodiment, Fig. 3 (not shown), the rings are biased by their own resilience into circumferential grooves formed in the bore of a stationary sleeve, and as before are free to be moved into succeeding grooves during movement of the piston in the brake applying direction and are prevented in the return direction.

Title: Process for bleaching textiles
IPC: D06L4/29
Filed: 1967-07-21
Abstract: and DIP. Textiles, e.g. cotton fabric, are bleached by impregnating them with an aqueous solution of sodium and/or calcium hypochlorite at a pH of 7-12 and such that the pickup of hypochlorite bleaching agent by the textiles is from 0.05-1%, calculated in terms, of active chlorine by weight of the textiles and then subjecting them to steam treatment at a temperature of 50 -140 C for 15-60 seconds in a steamer or pressure vessel. The textile which may be in the scoured or desized state may be impregnated at room temperature with the solution of the hypochlorite which may also contain a wetting agent, a chelating agent, e.g. ethylene diamine tetra-acetic acid or diethylene triamine pentaacetic acid, sodium chlorite or bromite or catalyst and/or accelerator, squeezed to the required pick-up of bleaching agent, optionally preheated using steam, infra-red or direct heat radiations, and then heated with steam which may be saturated or superheated. After steaming the textile may be washed and dried by means of a series of heated cylinders or a hot air chamber. In Fig. 2 the textile 10 is passed around rollers 11 in impregnation chamber 1 and passed by rollers 12 and 13 to preheating chamber 2 where it passes over rollers 14 and is conveyed to steaming chamber 3 where it passes over rollers 16 and is passed by rollers 17 to a second impregnating chamber 1A and second steaming chamber 3A where it passes over rollers 19 and is finally bleached. It is then passed through rollers 20 to a washing machine having compartments 5, 6 and 7 having a series of rollers 21 for passage of the textile therethrough and rollers 22 and 23 for nipping and is passed over rollers 24 to drying means 8 comprising a series of heated rollers 9 and is taken off on roller 25.

Title: Rc bridge variable frequency sinusoidal oscillator
IPC: H03B5/26
Filed: 1969-07-12
Abstract: A phase shift sine wave oscillator has an amplifier V whose output is connected to its input through a network as shown wherein F, G are capacitors (or resistors) and Q1, S1, T1 are resistors (or capacitors), the element P being either a switch or a resistor or a capacitor. If the amplifier V instead of being a voltage amplifier is a current amplifier, its input and output connections to the network are reversed. The output frequency is varied, without changing the voltage dividing ratio at E and therefore without affecting the output amplitude, by any of the following methods: (a) by opening or closing a switch constituting the element P to give two different frequencies whose ratio depends on a given relationship between F, G, Q1, S1, and T1 (b) by varying a resistance (or capacitance) constituting the element P to give a range of frequencies between the two frequencies in (a) or (c) varying a resistance (or capacitance) constituting the impedance T1 provided that the capacitors (or resistors) F, G are equal and that P2 = Q1. S1. In these arrangements, the element P is of the same impedance type (i.e. resistor or capacitor) as Q1, S1 and T1. If the amplifier is a differential amplifier, its second input is fed from the junction of two resistors connected from the output to earth.

Title: Apparatus and method for use in developing wound coils
IPC: H01F41/06
Filed: 1977-05-16
Abstract: Monitor position of winding flyer in relation to a machine frame, substantially continuously generate signals indicative of flyer position, and control relative jump of coil forms and flyer in response to signals. Jump is initiated during predetermined portion of a flyer revolution while flyer is in "jump window" relative to turn receiver. Energy stored in lost motion mechanism contributes to acceleration of jump mechanism and same mechanism absorbs and stores energy as moving structure stops. Parts of coil forms are adjusted substantially equal distances relative to a geometric center and turn receiver and winding head undergo relative movement to maintain mutually aligned relationships. Fast and consistently responsive latch mechanisms insure jump during fraction of flyer revolution in different machine cycles. Jump mechanism urged against latches by pre-loaded spring mechanism for increased acceleration and to absorb prime mover force at end of jump stroke. Fast response diaphragm piston operated latch mechanisms perit initiation of jump stroke.
