Patent GB-1266184-A (GB)
IPC: G01F1/38
Filed: 1969-06-24
Abstract: 1,266,184. Indicating-apparatus; pressure gauges. PENNWALT CORP. June 24, 1969 [July 5, 1968], No. 31855/69. Headings G1J and G1L. In a device for sensing the differential pressure across a restriction in a fluid conduit Fig. 1 (not shown), in which a flexible tube 16, connected upstream of the restriction, applies a fluidpressure to one side of a diaphragm 19 and a flexible tube 17, connected downstream of the restriction, applies a fluid-pressure to the other side of the diaphragm 19, and the diaphragm is reinforced by discs 30, 31 mounted on a shaft 56 via an annular seal 58 held in position by a sleeve 64 by a nut 65 threaded on the shaft 56. The right hand end 62 of the shaft 56 is attached by a screw 92 to the lower end of a leg 95 of a leaf-spring 90 pivoted about tabs 88 attached to an housing 86 and the arrangement is such that a free end 99 of the spring 90, as the diaphragm is moved to the left of Fig. 2, engages with a progressively increasing area the housing surface 87 to exert an exponentially increasing restoring force on the rod and diaphragm. The spring 90 is so shaped that the biasing force on the rod 56 varies with the differential pressure acting on the diaphragm 19 in such a manner that the diaphragm displacement from a zero position is linearly proportional to the square root of the differential pressure and hence the fluid-flow rate. A differential transformer 70, energized by an A.C. voltage, has an output voltage induced in the secondary winding determined by the position of an armature 78, mounted in a bore 76, in the left hand end 59 of the shaft 56. The output voltage produces a signal supplied to an indicating and/or control circuitry.

Abstract: 1295508 Lubricants BOEING CO 17 Dec 1970 60077/70 Heading C5F [Also in Division C7] Sintered solid lubricants are prepared by heating to at least 2400‹ F. a mixture of a chaicogenide powder from the group. Vb, VIb and rare earth chalcogenides (or a mixture thereof) and a carbide-forming refractory metal powder; compacting the mixture at a pressure of at least 2500 p.s.i. while maintaining the temperature and reacting the refractory metal powder with carbon while maintaining the temperature and pressure. The carbon can be obtained by using graphite pressing dies or by including an oil or a carbon-containing gas in the lubricant mixture. The metal powder (e.g. Mo, Nb, Ta, W) and chalcogenide (e.g. WS 2 , MoS 2 ) are preferably blended together and compressed to a slug. The slug is broken up, screened, heated and compressed so as to react with carbon. B, Fe, Ni, Cr and Co may be included in the mixture.

Abstract: 1296500 Pneumatic suspension systems ROBERT BOSCH GmbH 27 Aug 1971 [11 Sept 1970] 40365/71 Heading B7D In a closed pneumatic suspension system for a motor vehicle comprising air springs 11, 12, a level control valve 16, a reservoir 24, a compressor 41 and regenerating means 21 including a spring-loaded control piston 29, the piston 29 has a first effective area 31 of the piston 31 is subjected to the pressure in the reservoir 24 and a further effective area 30 subjected to the pressure in the springs 11, 12, and the ratio of the effective areas 31, 30 is equal to the ratio of the volumes of the reservoir and springs. A valve member 33 carried by the piston 29 is normally in contact with a valve seat 26 to prevent ingress of air through a filter 28 and non-return valve 27. Changes in the pressures exerted on the piston 29 under different vehicle loads result in no net change in the total force exerted on the piston, the valve member 33 leaving the seat 26 to allow ingress of air only if leakage reduces the total quantity of air in the reservoir and springs. In another embodiment, Fig. 2 (not shown), the pressure in respective air springs associated with front and rear axles is exerted on separate effective areas of the piston. In Fig. 3 (not shown), air flow to and from the springs is controlled by solenoid valves energized through level control switches.

Abstract: 1297031 Magnetic storage arrangements TOKO KK 24 Feb 1970 8860/70 Heading H3B In an arrangement for testing a plated wire storage array, Fig. 3, pulses from a generator 19 are fed via semi-conductor switches 21 and mechanical switches 20 to word lines 1-3m arranged in groups. Each group is connected to a respective busbar BB1-BB3. To test the first group comprising three storage sites 1-3, mechanical switches R1-R3 are closed and semi-conductor switches S1-S3 are closed in succession; coincident pulses may be passed in the plated wire 17, on which switching is also sensed. The actual sequence of pulses is conven - tional and is described with reference to Fig. 1 (not shown). Before the next group of three storage sites, comprising sites 2-4, can be tested switches R1-R3 must be opened, and switches R2-R4 closed. The delay involved in opening and closing is avoided in Fig. 4 where four busbars BB1-BB4 are used. The procedure for testing sites 1-3 is basically as before, but switches R1-R4 are closed while switches S1- S3 are closed in succession. To test the next group of sites, 2-4, switches S2-S4 are closed in succession. In the time taken to do this, R1 is opened and R5 is closed, so that as soon as sites 2-4 have been tested the next group of sites, 3-5, may be tested by closing switches S1, S3 and S4. During this, R2 is opened and R6 is closed, and so on until all sites are tested. The circuitry may be used to drive the plated wires rather than the word wires.

The wall W 1  is of "finite" thickness, that is the temperature at the cold face is dependent on the temperature at the hot face and the thermocouples are connected to the opposed ends of the network. The thermocouples may be replaced by thermistors. If the heat flux is required at a part of the wall other than at the heated face, the current through the resistor disposed at the corresponding point in the network is measured.

The ring 24 of the gear is fast with the input impeller I and the sun 13 is fast to one side wheel 14 of a bevel or intermeshed spur planet train, the carrier 25 of which is fast to the final output 21 and to the turbine T, the other side wheel reacting on a one-way detent 18. The gearings, which may alternatively be belt or ball friction, allow the secondary turbine TC to run more slowly than the impeller at stall and at the lower output speeds and to fun faster than the impeller at coupling and at the higher output speeds. A reversing gear-box is provided behind the converter, Fig. 2 (not shown), as disclosed in Specification 1,199,521. In a modification, Fig. 5 (not shown), two output shafts are provided for four-wheel drive, one, 21, being as in Fig. 1, and the other being parallel and coupled directly to the turbine T, the torque ratios between the two shafts being varied automatically. The secondary turbine TC carries spindles (76), Fig. 2 (not shown), on which bob weights (75) are mounted and are urged towards an inward position by springs (73). Arms (77) forming part of the bob weights engage slots in a ring (78) and spindles 22 also have arms (72) engaging other slots in the ring. As the bob weights move out, the arms (77) turn the ring which acts on the arms (72) to rotate the spindles 22 to vary the angle of the blades. The turbine TC may have fixed blades when a reactor R is not incorporated.

Title: Methods for the preparation by in vivo recombination of nucleic acid and polypeptide libraries and uses thereof
IPC: C12N15/10
Filed: 2001-05-14
Abstract: This invention provides novel methods of generating large, highly diverse, nucleic acid (and hence polypeptide) libraries. The methods exploit the discovery that recombination, particularly recombinase recombination can occur between two or more constructs of the same type (e.g. having the same origin of replication and/or the same regulatory or selectable markers). The methods thus involve introducing at least two members of an initial population of nucleic acid molecules into at least one cell under conditions were recombination (e.g recombinase mediated recombination) can occur between the nucleic acids. The nucleic acid molecules preferably comprise two or more individual nucleic acids each of which consists of a nucleic acid sequence that is identical for each molecule and that includes an origin of replication; and a nucleic acid sequence that varies between members of said population. Thus, a single type of construct is capable of mediates all of the recombination events providing substantially greater efficiency and the creation of substantially larger and more diverse nucleic acid libraries.
