Title: Regenerators for industrial furnaces
Inventor: KIESSEWETTER FRITZ DIPL ING
IPC: C13K1/10
Filed: 1961-05-26
Abstract: Magnesia bricks containing 0,1-0,5% of one or more boron compounds (calculated as B2O3) are employed in regenerators in industrial furnaces e.g. tank furnaces for glass manufacture. The boron may be introduced by impregnating the bricks, but preferably by mixing boric acid, alkaline earth metal borates or borax into the refractory batch from which the bricks are made. Thus such boron compounds may be added to sintered or unsintered magnesia which is then formed into bricks, after sintering if necessary. The bricks are resistant to rehydration, have good thermal shock resistance and high refractoriness under load. The regenerator may be a grate checkerwork. Application 21483/1900 and U.S.A. Specification 2,571,101 are referred to.
Patent ES-275173-A1 (ES)
Title: Improvements in or relating to the production of foundry moulds and cores
IPC: B22C1/22
Filed: 1962-03-05
Abstract: Foundry moulds and cores are produced by intimately mixing a major proportion of granular refractory material and a minor proportion of a mixture of a condensate of an aldehyde and a dihydric phenol and formaldehyde or furfuraldehyde, charging the mixture into a heated mould or core box and allowing the binder to harden therein. The dihydric phenol may be mixed with one or more monohydric phenols. The formaldehyde may be supplied as paraformaldehyde or heramethyline tetramine. The mould or core box may be initially heated to a temperature between 140 DEG and 350 DEG C. Suitable refractory material is silica sand, zircon sand or quartz. The phenol aldehyde condensate is prepared with deficiency of aldehyde. Suitable dihydric phenols are resorcinol 1,3-dihydroxy-5-methyl benzene p.p1-dihydroxy diphenyl methane and p.p1-dihydroxy diphenyl propane. Suitable monohydric phenols are phenol mcresol 1,3,5-xylenol. Suitable aldehydes are formaldehyde, acetaldehyde, furfuraldehyde. In the example phenol and formalin were heated in presence of HCl. The cooled mixture was adjusted to pH 9 with caustic soda, more formalin added and the mixture again heated. Rescorinol was added and the mixture again heated. Industrial spirit was added to the cooled product, and then paraformaldehyde and Redhill T sand. Test cores were prepared by blowing the sand/resin mixture into a heated core box and leaving the resin to cure therein.

Patent ES-313544-A1 (ES)
Title: Device for automatically controlling the pressure of an enclosed fluid
IPC: G05D16/18
Filed: 1965-05-29
Abstract: The pressure of nitrogen gas within the heat insulation space 4 between a liquid methane container 2 and an outer tank 3 is maintained within predetermined limits above the pressure of the surrounding atmosphere by connecting space 4 by ducting 5, 9, 9a to a flexible chamber 8 within a container 10 supplied with compressed air from a source 13 whereby the nitrogen can pass between the space 4 and the flexible chamber 8 without loss of volume. The upper limit of the nitrogen pressure is governed by the setting of an air relief valve 14 on the container 10 and the lower limit by the pressure available from a nitrogen make-up source 6 and pressure reducing valve 7. The outer tank 3 also has a relief valve 15 set to open at a higher pressure than said upper limit.

Title: Electrodynamic microphone having an adjustable tube for changing the directional characteristic of the microphone
IPC: H04R1/38
Filed: 1967-02-24
Abstract: In an electrodynamic microphone, a sleeve may be moved, from a first position in which it seals the rear of a microphone capsule and inhibits entry of sound at the rear, to a second position in which sound can enter at the rear. In the first position the microphone has an omnidirectional characteristic while in the second position it has a cardioid characteristic. A housing 1 (Fig. 1), comprises a soundpermeable cap 2 fitted to a tubular metal casing 3. The diaphragm 5 of a microphone capsule 4 communicates with outside air through a protective member 6 and, in one position of a sleeve 8, through ducts (not shown) at the rear 7 of the capsule 4. The sleeve 8 is urged by a spring 9 against a rubber ring 10 at the capsule rear 7. The casing 3 is encircled by a rotatable collar 11 (Fig. 2) in which is a plastics sleeve 12. A recess 13 in the sleeve 12 receives a lug 14 inside the collar 11. An inclined surface 15a of the sleeve 12 bears on a pin 15b disposed in a longitudinal slot 16 in the casing 3 and screwed to the sleeve 8. Rotation of members 11, 12 forces the pin 15b to move forwards or backwards over the cam surface 15a, whereby the sleeve 8 engages or disengages the ring 10 to close or open the capsule rear 7. Alternatively, the casing (3), Fig. 3 (not shown), encloses a tightly fitting rotatable sleeve (8). A pin (15) secured to the sleeve (8) is movable in a transverse slot in the casing (8). The end of the sleeve (8) facing the capsule (4) has eccentric apertures (18) covered with gauze (19) and which in one position co-operate with apertures in the front of the casing (3) which in turn communicate with the rear of the diaphragm (5). The sleeve wall has apertures (20), which may contain acoustic resistance, and which in one position co-operate with apertures (21) in the wall of the casing (3). In one position of the sleeve (8) the apertures (18, 20, 21) are such that sound can reach the rear of the diaphragm (5).

Suitable apparatus together with an appropriate control system is described. The articles to be sterilized are preferably subjected to motion within the autoclass during the process to avoid the effects of "cold" and "hot" spots and a rotating framework, to which packages may be clamped by their edges and which may be contained within the autoclass, is also described.

Patent ES-351249-A1 (ES)
Title: Distance sensing system for railroads based on track inductance characteristics
IPC: B61L17/00
Filed: 1968-03-05
Abstract: In an arrangement for determining the distance between a fixed point on a railway track and a rail vehicle, e.g. for determining the distance to go in a hump-yard classification track, a bridge circuit is connected to the rails at the fixed point for determining the inductance of the loop formed by the track rails and the vehicle axle from which the distance is determined. The bridge, Fig. 1, has the track loop represented by inductance 10 and resistance 12 connected in leg TI, a fixed resistance 17 in leg FR, a combination of resistance 20 and capacitance 22 in leg RC and a variable step impedance 28 in leg RB. Resistance 14 compensates for lead length when the bridge has to determine the distance for a number of different classification tracks. A logic circuit including a 0-10 counter is provided for controlling the operation at each count a short circuit is removed from a different impedance in the bridge leg RB. When the phase comparison of the voltages at points 16 and 26 indicates a phase difference in one direction the impedance is retained in the circuit, if the difference is in the opposite direction the last added impedance is again shorted out and the next lower value added at the next count. The impedances are calibrated in terms of loop distance and the sum of the impedances in circuit at the 9th count is an indication of the required distance. The tenth count restores the apparatus to zero.

Title: Nuclear reactor spring ferrule spacer grid
IPC: G21C3/356
Filed: 1969-06-23
Abstract: A bimetallic spacer grid for nuclear reactors comprising a plurality of spacer elements and spring ferrules which are mated to form the grid assembly. The spacer elements are comprised of a material having a characteristic low neutron capture cross section and are formed with outwardly extending arches while the spring ferrules are formed from a material which has better stress relaxation qualities than the material employed for the spacer elements and which will thus not suffer a substantial decrease in resiliency due to prolonged exposure to intensive radiation. The spring ferrules and spacer element arches cooperate to support each fuel element at five points of contact.
