Title: Anhydrous alkali-metal salts of 5.5-di-aliphatic-substituted barbituric acids, and processes of producing them
Filed: 1930-06-21
Abstract: Alkali metal salts of 5 : 5-disubstituted barbituric acids, in which one substituent is an ethyl or allyl group and the other is a non-aromatic group containing 3-8 carbon atoms but no triple bond, are prepared in the anhydrous form by treating the acid in alcoholic solution or suspension with an alkali metal compound other than the carbonate and evaporating the product in vacuo at a low temperature. The 5 : 5-disubstituted barbituric acids specified are diallyl-, isopropylethyl-, isopropylallyl-, n-butylethyl-, n-butylallyl-, sec-butylethyl-, sec-butylallyl-, n-amylethyl-, isoamylethyl-, cyclopentenylethyl-, sec-amylethyl-, cyclohexenylethyl-, n-heptylethyl-, and sec-heptylethyl-barbituric acids.  Sodium, potassium, and lithium are referred to as alkali metal components. The products, which usually contain less than 1 per cent of moisture, are an sthetics, hypnotics, and sedatives which do not deteriorate on standing.  An example is given of the preparation of sodium isoamylethyl-barbituric acid using ethyl alcohol as the solvent and an equivalent quantity of sodium hydroxide or sodium ethylate as the alkali metal compound.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the preparation of compounds in which the non-aromatic substituent contains 2-8 carbon atoms but no triple bond and includes diethyl- and isopropylbrompropenyl-barbituric acids among the starting materials.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to nuclear reactors
Inventor: BRADLEY NORMAN
IPC: G21C1/08
Filed: 1959-06-04
Abstract: 885,937. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. May 10, 1960 [June 4, 1959], No. 19148/59. Class 39(4) [Also in Group XIII] A nuclear reactor has means for passing a mixture of steam and water through the core to raise saturated steam, means for mixing feed water with the saturated steam and passing the mixture through the core to raise further saturated steam, and means for passing the further saturated steam through the core to receive superheat. Fig. 3 shows a reactor 10 to which are supplied saturated steam from evaporators 19 and water from a storage tank 48. Water (about 80% by weight) and steam are mixed at 25, heated and separated at 26; after three passes steam alone is superheated in a fourth pass and then used to heat the evaporators and to drive a turbine. The turbine condensate is heated and passed either to tank 48 or via a control heater 78 to the evaporators. Increased heating of the heater 78 by superheated steam reduces the steam temperature at the reactor outlet; the temperature at the turbine inlet is controlled by a valve 145 by-passing the evaporators, and pressure at the turbine inlet controls a fine control rod 140. Fig. 4 shows a cross-section of a reactor channel: a calandria tube 90 contains a pressure tube 16, within which are stainless steel support tube 106, stainless steel casing 114, and a stack of UO 2  pellets penetrated by stainless steel tubes. Fig. 7 shows a pressure tube of one of the first three passes, containing steam separator baffles 26, a feed water spray chamber 25, and a neutron absorber with helical passages. The tube has mild steel ends and a Zr middle. Part of the coolant flows outside the tube 106. Fig. 9 shows an alternative arrangement in which the steam-water mixture flows up over the fuel inside baffles and down between the baffles and the walls of the pressure tubes. Only the last pass has a steam separator 26a, water from which flows outside the baffles of the superheating tubes. The fuel in the first three passes is Zr-canned and of low enrichment; in the superheating pass stainless steel and higher enrichment are used. The reactor described has D 2 O as moderator under a blanket of He whose pressure is varied to control the reactor. D 2 O is used as a reflector above and below the core, with H 2 O at the sides. A shielded overhead charge machine 30 has a steam-pressurized vessel with a rotating magazine. Evaporaters, pipes and headers are thermally insulated. The concrete biological shield is air-cooled, and contains a discharge shoot which can be connected to the charge machine.

Abstract: 1421878 Hydraulic systems CATERPILLAR TRACTOR CO 2 May 1974 [2 May 1973] 19377/74 Heading F1P [Also in Division F2]  An hydraulic system comprises shock absorbing accumulators 48, 49 which are selectively connectable via a lock valve 10 with jacks 12, 13 subject to a load. The lock valve 10 comprises check valves 52, 53 located between lines 42, 43 leading to jacks 12, 13 and lines 50, 51 leading to accumulators 48, 49. Each ball of the check-valves 52, 53 is movable off its seat by a piston 56, 57 actuable by pressure transmitted to a chamber 59 between the pistons. Such pressure is selectively applied by a solenoid-operated pilot valve which in one position connects chamber 59 to drain as shown via line 69 and in its other position connects the output from a pump 15 to the chamber 59 to urge pistons 56, 57 away from each other. The jacks 12, 13 are brought to a fixed position by operation of conventional control means comprising control.valves 18 leading from pump 15 and to reservoir 16 via lines 20, 21 and 22, 23 respectively, lock valves 26 serving to hold the load in a fixed position if the check-valves 52, 53 of lock valve 10 are also closed. However, valves 52, 53 can be opened to permit the jack pistons to move from the fixed position when, for instance, the jacks are being used in earth working implements such as a grader blade of a grading machine which might encounter large obstacles, the accumulators 48, 49 thus permitting retraction of the jacks in such a case. Lock valve 10 and pilot valve 66 may be replaced by a pair of simultaneously operable solenoid valves Fig. 2 (not shown).
