Title: Process and Apparatus for Producing Low-purity Oxygen
IPC: F25J3/04
Filed: 1979-05-17
Abstract: Low purity oxygen is produced by fractional distillation of liquefied air in a double distillation column 14,25 and an auxiliary distillation column 43. Feed air is supplied at two different pressures. The disclosed methods of handling intermediate oxygen- enriched liquid produced by the two columns and removing nitrogen-rich gas from the auxiliary distillation column permit the system to operate with lower energy requirements and smaller column diameter than conventional systems. <IMAGE>

Title: Improved aquaculture tank
IPC: A01K61/00
Filed: 1979-05-18
Abstract: An aquaculture tank comprises a vessel 1 of circular cross-section in a horizontal plane which is divided into a series of annular concentric compartments 5, 6, 7 of increasing volume in the radially outward direction. Water supply nozzles 12 create, in use of the tank, a flow of water having at least a component of velocity in a circumferential direction in each compartment. A first fish barrier 20, 21, 22 is arranged across each of the compartments to prevent fish swimming complete circuits around the compartments. Second fish barriers 29, 30 31 are suspended in the compartments 5, 6, 7, respectively, from an arm 26 which is rotatable about a shaft 27 for the purpose of moving the barriers 29-31 around the compartments in the direction of the circumferential water flow component to trap the fish in small sectors of the compartments between the two fish barriers. Removable partitions 14, 15 facilitate transfer of trapped fish from one compartment to another. Means may be provided for grading the fish according to size before transferring them from one compartment to another. <IMAGE>

Patent GB-800179-A (GB)
Abstract: 800,179. X-ray apparatus. SIEMENSREINIGER-WERKE A.G. Jan. 10, 1957 [July 7, 1956], No. 1030/57. Class 98(1) In X-ray apparatus having a housing for a Potter-Bucky grip mounted on a frame on a carriage movable vertically on a stand, the housing is rotatable about an axis which is perpendicular to the plane of the housing and passes through the centre of the housing. As shown in Figs. 1, 3, sleeves 3, 4 are slidable on the columns 1, 2 of a stand; they may be counterweighted and clamped in any position. Arms 7, 8 extending from carriages 3, 4 and connected by an arm 9, support a frame 12 pivoted on pins 10, 11. The housing 22 for a Potter-Bucky grid and its operating mechanism, which also supports a fluorescent screen or photographic material, is mounted on a ring 17 rotatable on rollers 13, 14, 15, 16. The patient may rest against a plate 25 of material transparent to X-rays. The housing is rotatable from a vertical to a horizontal position about pins 10, 11, the angle of rotation being indicated on a scale 26, and is held in adjusted position by a rod 27 sliding in a sleeve 28 and clamped by a lever 29. Rotation is limited by a knob 30 on rod 27. A recess 31 in cover 25, opposite the part of the housing 22 containing the grid actuating mechanism, supports the patients' chin in chest examinations. Where the skull is irradiated laterally, the housing is turned through 180 degrees so that the shoulder is brought under it. The apparatus may also be used in conjunction with a patient's table. Patients may be examined seated on the cover 25, when the housing 22 is in the position shown in dotted lines in Fig. 1. In this case, a foot support 32 hinged to the housing is swung out therefrom. Guide members 33, 34 may be fitted on the housing 22 for the attachment of a back rest 35 or a head support.

Patent GB-2054397-A (GB)
Title: Method and apparatus for stirring particles in suspension such as microcarriers for anchorage-dependent living cells in a liquid culture medium
IPC: B01F15/00
Filed: 1980-07-16
Abstract: The method involves stirring the particles in the liquid medium in a stirring vessel having a bottom which is shaped to prevent the accumulation of particles thereat due to the motion of the liquid medium set up during stirring. The vessel is of cylindrical form and the bottom has an upstanding conical portion 3 with a rounded apex 4. The junction between the bottom and the vertical wall 1 is radiussed at 6 to form an annular trough or channel 5 between the wall and the conical portion. The shape of the vessel permits the medium to be stirred at lower speeds thus avoiding damage to the growing cells. <IMAGE>
Patent GB-2059176-A (GB)
Title: An electrical generator
IPC: H02K1/02
Filed: 1980-09-04
Abstract: An electrical generator, particularly a three-phase generator without slip- rings, for motor vehicles is proposed in which the rotor shaft 15, 16 acts as a magnetically hard member in the magnetic circuit of the rotor, thereby facilitating the build-up of self- excitation. The rotor shaft is thus made of steel (three examples are given) and has mounted thereon a first pole wheel 17 which is connected by way of a non-magnetic ring 18 to a second pole wheel 19, which is thus not directly secured to the shaft 15. End plate 11 carries a mount 21 for the excitation winding 22. <IMAGE>
Patent GB-2060339-A (GB)
Title: Overload clutches
IPC: F16D43/206
Filed: 1979-01-29
Abstract: An overload coupling (9) comprises a power input member (18), carrying spring-loaded balls (20), and a power output member (13) having formations (36, 37) Figure 4 (not shown) which interfit with similar formations in an intermediate coupling ring (27). The balls (20) engage recesses in the coupling ring (27) so transmitting drive from the input member (18). However, overload causes the balls (20) to move into deeper recesses, which allows the coupling ring (27) to move out of engagement with the output member. Braking of the coupling ring, which is achieved by reducing the speed of the input member 18, causes the balls (20) to return to the shallower recesses and re-establishes the engagement between the coupling ring (27) and the output member (13). The coupling ring (27) is braked by a shoe (49) when, on reducing speed, the centrifugal force on the shoe becomes less than that of a spring (56). <IMAGE>

Patent GB-2091937-A (GB)
Title: Mass analysis sample ionisation
IPC: H01J49/14
Filed: 1982-01-27
Abstract: The ionisation, for mass spectrometric analysis of materials which are normally solid and cannot be vaporised in a stable form, including many compounds of bio- medical significance such as saccharides, peptides and antibiotics is effected by subjecting a mobile sample of the compound to bombardment by a beam of neutral atomic or molecular particles. A target coating is prepared in which a sample of the compound is present in a mobile condition, eg. in a molten state or in solution in a medium of low volatility such as glycerol, at the surface of the coating and the atom beam is directed at a small angle, typically from 10 to 30 DEG  with respect to the surface. The kinetic energy of the beam is such that during mass analysis a range of ion species is observed which includes both pseudo-molecular ions and structurally significant fragment ions. As shown, primary argon ions, produced in gas-filled discharge chamber 21, are directed into an argon-filled chamber 30 where resonant charge exchange occurs to provide a beam of neutral argon atoms, typically of energy 2-6 kev. The neutral beam is incident on the surface of target 38, which may be suitably heated or cooled and whose polarity determines whether positive or negative ions are selected for the slit-system of the mass analyzer, eg. of the double focussing type. <IMAGE>
