Title: A chemical cartidge for breathing apparatus
Inventor: HUNNEBECK VOLKER
IPC: A62B7/08
Filed: 1992-09-24
Abstract: Chemical cartridge for breathing equipment comprising a casing 5 accommodating an oval container 3. A duct 6 is formed between the casing 5 and the container 3 in order to allow exhaled gas which enters the cartridge through an upper end to enter the container 3 via air permeable upper and lower end faces 4a and 4b and an air permeable side surface 4c. A chemical such as potassium peroxide accommodated within the container 3 converts the exhaled carbon dioxide and water vapour into oxygen. Gas flows out of the container via nozzles 7 having air permeable portions 7b which are interconnected via a cavity 8 having air permeable side walls 8b. A space 9 holding the chemical is formed between the bottom of the container and the cavity. The arrangement ensures uniform reaction by all of the chemical and a uniform distribution of temperature in the cartridge. <IMAGE>

Patent GB-959258-A (GB)
Abstract: 959,258. Gyroscopic apparatus. GENERAL PRECISION Inc. Dec. 14, 1962 [Dec. 14, 1961], No. 47213/62. Heading G1C. [Also in Division E2] A gyroscope, particularly a tight loop stabilized one, is supported about each precession axis by a pair of flexure pivots, the restraining torque developed by the flexure pivots when reflected being compensated by mechanical, electrical or magnetic springs or combinations thereof. As shown a rotor casing 40, Fig. 1, is mounted within a gimbal by a pair of crossed flexure springs and the gimbal is supported within casing 26 by another such pair 42, 44. The casing 26 is slowly rotated within a housing 22, about the spin axis by motor 35 and gearing 37, 39 to reduce the effects of disturbing torques, and the gyroscope is temperature controlled by heating jacket 33. To eliminate strain on the pivots caused by different thermal expansion of the various gyro components, one pivot 42 is made stiff in the axial direction by being formed of crossed leaf springs whilst the other pivot 44 is made soft by being formed of crossed wires 124, Fig. 5. The compliance of the pivots is made equal in all directions so that no spurious torques are generated during acceleration. A mechanical spring compensator can comprise a helical spring 139 which exerts no torque about the precession axis in the null position of the gyroscope, but when the latter precesses it applies a force to assist such precession and counteract the restraint of the flexure pivots. An electrical spring compensator 51 is formed from a coil 50 through which D.C. current flows, supported within a housing 52 of magnetic permeable material secured to casing 26, there being annular pole faces 54, 56 which cooperate with a D.C. carrying armature coil 58 carried by an arm 60 projecting from the rotor casing 40. In the null position the net torque exerted on coil 58 and arm 60 is zero but increases when the rotor precesses. The electric spring 51 may form a fine adjustment for the mechanical spring 139. Four pickoffs are provided on the cover plate 24 of housing 22 to co-operate with an armature coil 74 on arm 60. Four torquing coils 80 are provided. In modifications a magnetic compensating spring, Fig. 12, (not shown) or different forms of electric spring, Fig.11, and Fig.13, (not shown) are used. Alternatively a wire 318, Fig.14, is attached at one end to the rotor casing 302, passes through a central aperture 314 thereof to have its other end anchored by a block 324 to a stiff but slightly flexible element 326, and a spring 328 adjusts the downward pull exerted on wire 318.

Abstract: A microprocessor has RAS and CAS outputs for exclusive coupling, via a bus, to RAS and CAS inputs of a private DRAM. The microprocessor has a DRAM Control Register having at least one bit which is set to designate whether the DRAM is private to the microprocessor, a read circuit which reads the one bit and determines whether the bit is set, and a control logic circuit coupled to the read circuit for controlling functions of the microprocessor according to whether the DRAM is private to it. If the DRAM is private, and successive cells to be accessed are within the same page, the RAS input can remain asserted, shortening the access time.

Title: Method for producing a pipe and apparatus for the same
Inventor: KURODA YOSHITAKA
IPC: B21C37/28
Filed: 1996-04-12
Abstract: According to the present invention, in the first process, a pipe end (3) of a long pipe (1) in bent with a radius of curvature which is larger than a minimum radius of curvature to form a large R portion. That is to say, bending with a large radius of curvature (R) is performed to form a large R portion in a region 9A in which cracking or excessive reduction of plate thickness of the bend outer-side portion, or buckling of the bend inner-side portion (9b), does not occur. Subsequently, in the second process, the pipe (1) is bent with a small radius of curvature to form a small R portion by pressing a pipe-end portion (3) of the pipe from a pipe-end direction while fixedly holding the bend side wall of the pipe (1) in a fig. 7. In this way, it is possible to obtain an R-minimum elbow (9) configuration irrespective of magnitude of an amount of elongation of material and further without special equipment or mechanisms, by minor modification of present equipment.

Title: Mechanical riser pin and box coupling and method
Inventor: LEVETT BRYCE A
IPC: E21B33/038
Filed: 1997-07-24
Abstract: The coupling 10 is provided with an external annular pin shoulder 45 that engages the annular end 44 of the box 12 when the coupling is initially engaged. The coupling 10 is suitable for tubular riser sections extending from a drilling structure above the water surface to the seabed. Dogs 22 carried on the box 12 are adjusted radially to engage and lock the box to the pin. Tapered bearing surfaces - formed on the dogs 22 and on the pin 11 engage and force the pin and box together as the dogs are adjusted radially. Engagement of the box 12 and external pin shoulder 45 stops movement of the pin and box toward each other so that continued adjustment of the dogs 22 provides an increasing pre-load bearing pressure between the pin and box. Full engagement of the box end 44 and the pin shoulder 45 permit the application of large pre-loading force, prevent the dogs from distorting the box, protect the overlap area between the pin and box from contamination and provide positive visual confirmation of shoulder engagement.
