Title: Electrodeposition process
IPC: C09D5/44
Filed: 1972-11-08
Abstract: 1408279 Electrodepositable composition VIANOVA KUNSTHARZ AG 8 Nov 1972 [8 Nov 1971] 51541/72 Headings C3P C3B and C3R [Also in Division C7] An electrodeposition paint comprises an electrodepositable water-soluble binder and an at least partially soluble complex of a metal salt with ammonia. Preferred complexes are those of phosphates or chromates of metals of Groups Ib, IIb and VIII, particularly zinc phosphate. The use of phosphates of copper, zinc, cadmium and, for comparison, aluminium (which does not form a complex) is also described. The paint may also contain chromates of non-complex-forming metals such as strontium and pigments, fillers and solvents. It may be formed by adding the preformed complex to the binder, which is neutralized with excess ammonia or an amine, or by neutralizing a mixture of the binder and the metal salt with ammonia. The exemplified binders are a polybutadiene-maleic anhydride adduct, a thermosetting epoxy resin ester and a polyester derived from 1,2-propylene glycol, pentaerythritol and a maleinized mixture of rosin, tall oil fatty acids, linseed oil, dehydrated castor oil and tung oil as described in Specification 1,166,249.

Title: Nuclear Reactor Containment System for Metropolitan Sites
IPC: G21C9/008
Filed: 1968-11-11
Abstract: 1,169,848. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 11 Nov., 1968 [29 Dec., 1967], No. 53312/68. Heading G6C. In a containment vessel for a steam or watercooled nuclear reactor, the escape of radioactive substances is prevented for both slow and explosive leaks in the reactor system. During a small leak in the primary coolant system steam from the reactor pressure vessel 10 passes from the dry well 11, through conduit 15 to the water in tank 14 where it is condensed. Air from compartment 11 is vented to the reactor building gas plenum 35a. Where a sudden increase of pressure occurs within the pressure vessel, the disc 21 is ruptured to permit a gravity flow of water from tank 12 into the vessel 10, the released steam from the core being condensed in 12. A sudden rupture of the primary coolant system produces a corresponding increase of the pressure in well 11 and in compartments 11a and 11b. Discs 17a, 17b, 32a and 32b rupture, steam and air are forced into tank 12. The steam is condensed, the air released into containment building 35 and water from 12 floods 11. As the gas volume 35a is large, the pressure change is small. The pump 39 exhausts gases from the space between 36, 37 into 35, thereby reducing radio-active escape.

Two beads are arranged in parallel on the rail.  As shown in Fig. 6 each braking body 8 may be asymmetrical in cross-section and may have entering and leaving sections I and III of less and greater inclination respectively, separated by a level section II. Two "mirrorimage" bodies may be arranged in adjacent channels 7, Fig. 8, with upper edges of small radius of curvature facing to provide strong braking or with upper edges of greater radius facing to provide weaker braking, (Fig. 7, not shown), (i.e. orientated as in Fig. 6). Recesses 21 alongside each channel 7 accommodate the upper edges of the braking body when compressed as shown in dashed lines. The channels 7 and recesses 21 are continuous; the channels are covered between braking bodies, and the braking bodies are spaced and retained, by cover strips whose edges occupy the recesses 21 (Fig. 9, not shown). The longitudinal cross-section of the top of a braking body may be a smooth curve of gently rising and steeply falling configuration instead of being in sections with defined boundaries (Figs. 4, 5, not shown).

Title: Phase-Shift Sign Indicator circuit
IPC: C01B33/113
Filed: 1966-12-14
Abstract: 1,164,269. Detecting sign of phase difference. COMPAGNIE DES COMPTEURS. 14 Dec., 1966 [25 Jan., 1966], No. 55927/66. Heading H3T. The sign of the phase difference between two signals is found by converting them to binary logic signals, detecting separately the periods when the various possible combinations of the logic signals occur and storing during a halfcycle only the combination which occurs first in that half-cycle. In Fig. 6 the input signals A and B are converted to binary form at 32, 31 and the complements of these derived at 34, 33. The four possible combinations of these four signals are combined in transistor NOR-gates 41-44 which feed from identical storage circuits 51-54. Each such circuit has an initial NOR gate fed with the logical product and the circuit output for self-latching. The second NOR gate (e.g. S 1  in circuit 51) has as inputs (a) the output of the first NOR gate comprising #A.B.S 1 , (b) the #A signal to limit the storage to the period when the A signal is in its appropriate halfcycle, and (c) the output of S 2  to inhibit the storage when the S 2  circuit is storing. Thus, for one phase relationship between the A and B signals, S 1  will store in one half-cycle and S 3  in the next, while for the other phase relationship S 2  will store in one half-cycle and S 4  in the next. Indication of the phase relationship is obtained by combining S 1  and S 3  to form an output S<SP>1</SP> and combining S 2  and S 4  to form an output S. The arrangement can be extended to deal with three input signals by increasing the number of circuits 41, 51 to eight to cater for all the possible combinations of A, B and C, each storage circuit having five inputs to its second NOR gates (Fig. 13, not shown) so that it can be inhibited by all the others appropriate to the same half-cycle. Four output terminals are provided to indicate the relationship between each pair of input signals. Logic elements other than NOR gates may be used.
