Abstract: 1,009,691. Lasers. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. April 12, 1962 [April 17, 1961], No. 14187/62. Heading H3B. In a laser using four energy levels, non- radiative energy exchange between neighbouring ions (cross-relaxation) contributes to the over population of one level. In Fig. 4, the energy difference between levels 1 and 2 is the same as that between levels 2 and 4. On excitation by a pumping frequency P = v 12  = v 24 , ions may be raised from level 2 to level 4 either by the pumping frequency P or by non-radiative transfer from another ion falling from level 2 to base 1. With level 4 over populated, a signal S can be amplified by stimulating an energy drop from level 4 to level 3. A ruby crystal can be used in this manner, a unidirectional magnetic field of about 1000 oersted being used at an angle between 0 and 20 degrees to the C axis of the monocrystal to produce Zeeman splitting. In another arrangement, Fig. 9, the energy difference between levels 3 and 1 is double that between 4 and 3 so that v 31  = 2v 34 . An ion may be raised from level 3 to level 4 by a single quantum of v 34  (the pumping frequency P) and from level 1 to level 3 by the simultaneous absorption of two quanta of v 34 . Levels 1, 3 and 4 are substantially uniformly populated and level 4 is more highly populated than level 2. A signal S of frequency v 42  corresponding to the energy difference between levels 4 and 2 can then be amplified by stimulation. As shown, the pumping frequency is less than the signal frequency. Modified arrangements are described.

Abstract: 1,027,412. Block signalling. TELEFON A.B., L. M. ERICSSON. Jan. 17, 1964 [Jan. 17, 1963], No. 2255/64. Heading B7N.  In an automatic block signalling system in which each block is divided into a short entry track circuit and a second track circuit which extends over the remaining length of the block and is provided with an entry signal post with means for displaying a permissible speed for a train entering the block, each post is provided with a coded signal receiver for receiving information from the subsequent block signal post regarding the position of the train in advance, a code signal analysing means for determining from the received information the correct speed for display and means for transmitting coded information relating to train position to the preceding signal post. Each block section is divided into a number of modules, i.e. distances determined by the track grade and the braking capacity of the trains and the speed displayed at each signal post is determined by the number of free modules ahead of the post. Each signal post is provided with a two-digit number and signalling is by means of four voice frequencies-any two of which represent a number between 1 and 6. Assume a train is in the block associated with signal 13 to the right of Fig. 2, line a, occupation of the block, signalled by its track circuits, controls the block signal to stop and the signal's number is transmitted to the preceding post 14. On receipt of this signal, post 14 displays a speed signal indicative of two clear modules and repeats the signal to its preceding post 15 which displays a signal indicative of five clear modules and repeats the signal number 13 to signal post 23 which in turn repeats it to post 24. Since there are now 9 clear modules ahead of post 24 this signal displays a " cleartrack " signal and sends this " clear track " signal, i.e. the number 12 repeated, to its preceding signal post. When a train enters a block section its associated signal is set to stop and during the period the short track circuit is occupied no signal is transmitted to the preceding block signal. When this short circuit is cleared the block signal is transmitted, as previously explained, preceded by the signalling of digit 6 which terminates the locking of the stop signal at the preceding block signal post.

IPC: B07B4/02
Abstract: 1,050,755. Separators. PANGBORN CORPORATION. August 20, 1965 [Sept. 8, 1964]. No. 35763/64. Heading B2H. Apparatus 10 for separating, e.g. abrasive blasting particles from an abrasive-contaminant mixture comprises a housing with an inlet 12 for the mixture, a screw or other conveyer 14 to move the mixture from the inlet and a separating zone 36 in the housing. Coarse scrap 18 is removed by a mesh scalping drum 16 and discharged into a collector 20. A metering slot 31 including an adjustable gate 34 is provided between the separating zone and conveyer to permit the mixture to fall into the separating zone. If the slot become clogged a vane 33 of the gate 34 is rotated away from the lip 32 and a vane 35 is simultaneously rotated into its place. When more contaminant mixture is fed to the slot 31 than can pass over it the excess mixture falls into an overflow conduit 57 for recirculation back to the scalping drum. The light contaminant is progressively removed from the mixture at various levels in the separating zone so that pure abrasive particles may be collected in the bottom of the separating zone. As described, this separation is effected by a refiner, whereby an air curtain directed across the separating zone from an inlet 38 divides the light-weight contaminant across a first skimmer plate 42, the remaining mixture being further separated across a second adjustable skimmer plate 46 and a third adjustable plate 48. The pure abrasive passes through a screen 52 into a bin 54. The air curtain flows out of the separator via an adjustable vent 40 and carries with it the fines. The heavy refuse fraction from a conduit 50 may also be recirculated through the separation zone 36 for further separation.

Abstract: 1,227,417. Vehicle roofs. M. L. LACY. 1 April, 1968 [6 April, 1967], No. 15556/68. Heading B7B. [Also in Division G2] A solar energy screening and filtering device e.g. for use in windows, automobile tops, aeroplane canopies, space helmets, eyeglasses, windshields, and signs, comprises a hermetically sealed cavity 22, Fig. 3, formed between two transparent plates 18 and 20 and a reservoir 60, Fig. 4, containing two immiscible liquids connected to the cavity 22 by conduit 58 to a high gravity point 54, and by conduits 62, 64 and 66 to low gravity points 50 and 52. In one embodiment for use in the roof of a motor vehicle the reservoir 60 contains equal amounts of liquids such as a heavy glycol and a mineral oil. A pump 68, actuated by a solenoid switch 70 or 71, pumps the heavy liquid through conduit 66, filter 72 and conduits 62 and 64 into the low gravity openings 50 and 52 of cavity 22. The system is completely filled with liquid and air expelled from it by means of a bleeder valve 74. Expansion of the liquid is taken up by the expansion device 76 which consists of a rubber ball surrounded by a coarse mesh wire. Alternatively a rubber diaphragm plate over a hole in the side of the reservoir may be used. To assist heating of the vehicle by allowing infra-red rays to be transmitted through the cavity 22, the heavy liquid is pumped out of the cavity 22, and in so doing the light liquid is forced into the high point of gravity opening 54 thus presenting a cycling of the liquids with the interphase between them moving in the direction of the pumping so that the interphase in the reservoir rises to the high point of gravity 54. The system may employ three or more immiscible liquids and more than one reservoir.

Abstract: 1,233,322. Actuation of switches. UNELEC. 3 April, 1969 [5 April, 1968], No. 17675/69. Heading H1N. A device for controlling the opening and closing of a switch of the kind in which opening and closing are effected by releasing respective energy storing springs (not shown), comprises two independent mechanisms for respectively controlling the release of the opening and closing springs, the closing mechanism comprising three members 7, 16, 23 acting in series, one upon the other through two releasable couplings 14, 15 and 21, 22, one of which may be released by each of three other members 31, 36, 43 which are respectively operated by a remote device preventing closure; actuating of the opening mechanism; and by the contacts being in the closed position. The energy storing springs are rewound immediately after release by electric motors (not shown). The first member 7 is pivoted to an operating lever 2 which can be moved manually or by an electromagnet acting upon pin 5. The third member 23 is pivoted to a lever 25 which acts on an arm 1 to trip the closing spring. Members 7, 23 are biased by torsion springs 11, 28 into engagement with pins 15, 21 on the second member 16. Moving lever 2 in the direction of arrow 52 releases the closing spring; as the contacts close a cam 48 rotates allowing a follower portion 47 of lever 43 to fall so that a pin 50 strikes member 7 to disengage it from pin 15. Thus, maintained or repeated actuation of lever 2 cannot re-release the spring while the contacts are closed; pumping is prevented. The opening mechanism includes a lever 34 which may be operated manually or electromagnetically to release the opening spring through linkage (not shown). When lever 34 is actuated in the direction of arrow 54 a pin 41 strikes the member 7 to disengage it from pin 15 so that closing cannot be initiated while the opening lever is actuated. The member 23 can be disengaged from pin 21 by an electromagnet energized remotely and acting through a link 31.

Abstract: 1,256,874. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 14 Feb., 1969 [23 Feb., 1968], No. 9037/68. Heading G6C. A nuclear reactor which is cooled by, and whose core is submerged in, a liquid, has this liquid contained by a continuous layer of the liquid frozen into the solid state and supported by a support structure. In one embodiment, as shown in Fig. 1, a sodium-cooled fast breeder reactor has a concrete vault pre-stressed by means of ducted cables 9 to serve as a tank, the wall 1 of which is provided with a membrane lining 2 of mild steel. Pipes 3 for a cooling or refrigerating fluid 4 are embedded in the wall 1, and further pipes 5 are provided on the outer side of the lining 2, the contact positions of the pipes 3, 5 with the lining 2 being in staggered relationship. Cooling or refrigerating fluid 6 flows through the pipes 5, and may be the same fluid as 4, where this is compatible with sodium. The fluid 4 may be water, "Freon" (Trade Mark) or "Arcton" (Trade Mark) but as these are strongly reactive with sodium, the fluid 6 is different and may be the Na/K eutectic or a pressurized gas, e.g. He, A or CO 2 . The fluid 4 may also be one of these. With a mean temperature of about 400 C. of a sodium pool P contained in the lined vault, the cooling is designed to keep the temperature of the lined surface of the concrete wall 1 well within the limit prescribed for concrete, and to keep the temperature gradient across the wall 1 to about 50 C. It may be necessary to augment the cooling effect produced by the pipes 5 and fluid 6 by the provision of thermal insulation 7 over the pipes 5. The molten sodium of the pool P freezes in contact with the lining 2, the frozen volume being indicated by the shaded area 8 and the boundary of the volume by the broken line 9. The advantages of this frozen sodium volume which contain the molten sodium are compatibility, self-sealing property, and ability to act as cold trap for impurities. A large (600 M.W.(E.)) power generating fast breeder reactor cooled by liquid sodium and incorporating a concrete vault of the above type is described (Figs. 2 and 3, not shown). The invention is applicable to other coolants such as liquid metals other than sodium, polyphenols, and fused salts. An example of the last-named is a mixture of lithium fluoride and beryllium difluoride.
