Title: Disc for disc brakes
IPC: F16D65/12
Filed: 1963-09-17
Abstract: In a disc for a disc brake of the kind set forth in the parent Specification carrying a number of angularly spaced blocks of friction material which are of greater axial thickness than the disc and which are mounted in openings in the disc in which they are retained by readily releasable retaining means and from which they are removable in a radial direction on release of the retaining means, grooves are formed in the ends of the friction blocks for engagement with the ends of the openings in the disc whereby the friction blocks are located against axial movement relative to the disc. As shown in Fig. 1 angularly spaced blocks of friction material 15 are slidably received in angularly spaced openended notches 13 in the disc and retained by means of clips 18. As shown in Fig. 6 two discs may be enclosed in a housing 27 provided with an opening 28 of sufficient dimensions to permit the removal and replacement of friction blocks without dismantling any other part of the brake, the opening normally being closed by a removable cover 29.
Patent ES-338757-A1 (ES)
Title: Container having a composite refractory wall
IPC: F27D1/00
Filed: 1967-03-31
Abstract: A composite refractory lining for use in a blast furnace having a shell C comprises an inner layer of bricks B and an outer layer of bricks A wherein the outer layer A has a higher thermal conductivity than the inner layer B. The inner layer B is of conventional refractory material such as aluminosilicate based material whereas the higher conductivity outer layer A comprises natural graphite or silicon carbide with, e.g. clay or carbon as the bonding agent, kaolinite type clays being preferred. Other materials such as electrographite, self-bonded or ceramic-bonded silicon carbide may alternatively be employed. The outer layer of bricks A may be heterogeneous wherein every alternate brick A is of high thermal conductivity and the remainder of low conductivity. In another construction the layer of high thermal conductivity material may be sandwiched between an inner layer and a third layer both of low conductivity material. Cement and ramming material of high conductivity are used respectively to join the bricks of the inner and outer layers together and to fill in any voids such as at D.

In the construction shown the piston 2 and slack adjusting ring 6 are provided with complementary frusto-conical surfaces, the adjusting ring 6 having a screwthreaded outer periphery for co-operation with the slack adjusting member. The piston 2 is provided with a groove 11, the outer end wall 12 of which defines the limit of normal travel of the brake actuating movement. The adjusting ring 6 is approximately triangular in outer shape (Fig. 3, not shown). In a further embodiment (Fig. 2, not shown) the screwthreaded slack adjusting member is in the form of a pin permanently connected to one piston and projecting into a recess in the other piston. The slack adjusting ring has an internal screwthread to co-operate with the slack adjusting member and an external frusto-oonical surface for co-operation with a complementary surface of the other piston.

Title: Production of Expanded Olefin Polymer Moldings
IPC: B29C67/20
Filed: 1967-05-27
Abstract: Expanded olefin polymer mouldings are prepared by mixing particles of an expanded polymer of ethylene or propylene (whose X-ray crystallinity at 25 C. is more than 25%, the particles having a diameter of 3-50 mm. and a bulk density of 5-200 gm/litre) with a curable binder which is free of solvent, compressing the mixture by 5-70% of its original bulk volume in a mould and allowing to cure under pressure. In Example 1 expanded polyethylene particles are mixed with pentaerythritol triglycidyl ether and p,p-diaminodicyclohexylamine and is placed in a wooden mould lined with polyethylene sheeting (25 x 12À5 x 5 cm.) and having a lid of the same material. The contents of the mould are compressed to half their original volume and cured at room temperature. In Example 3 an elevated temperature (70 C.) is employed to cure the mixture. Instead of a mould the mixture may be fed between two conveyer belts to form a sheet, or to a channel provided by four conveyer belts to thereby provide a strand.

Patent ES-347715-A1 (ES)
Title: Improvements in or relating to a timepiece
IPC: G04F5/16
Filed: 1967-11-28
Abstract: The timepiece described in the parent Specification is modified to use a radio-active source emitting radiation at a constant energy level. Fluctuations in the timepiece supply voltage cause changes in the energy level at which the discriminator operates to reject pulses of a lower energy and to pass pulses of a higher energy, thus changing the number of pulses counted per second which in turn affects the accuracy of the timepiece. The present invention overcomes this difficulty by using a source emitting alpha or gamma rays having discrete energy levels so that the discriminator may be dispensed with or alternatively it may be used merely to ensure that rays at lower and higher discrete energy levels than the level of the counted rays are not counted, their energy levels being sufficiently separated so that variations in the cut-off level of the discriminator do not affect the number of rays counted. A gamma ray emitting source such as iodine 129 or uranium 233 is preferably used and is applied to the top of a metal case within which the counter is located, the case permitting penetration by the gamma rays.

Patent ES-416059-A1 (ES)
Title: Crosspoint switching matrix incorporating solid state thyristor crosspoints
IPC: H03K17/72
Filed: 1973-06-19
Abstract: Disclosed is a crosspoint matrix applicable for use in telecommunications switching networks. Each crosspoint includes a silicon controlled rectifier or semi-conductor thyristor plus a suitable gating member. A marking signal of voltage higher than a reference voltage suitably marks a selected conductor of one multiple. A voltage more negative than that of a second reference of the other multiple suitably biases a conductor of the other multiple. Concurrently therewith, a triggering signal is transmitted to the gate of the biased crosspoint completing a path across the matrix. The threshold or reference voltage levels used are considerably separated from the voltage level band used in passing information across a triggered crosspoint, thus resulting in no interference between crosspoints.
