Title: An adjustable bearing mounting for a rotor
Inventor: HOLM ARVID
IPC: F16C25/08
Filed: 1985-12-31
Abstract: In a bearing mounting for a rotor (2) of a screw compressor the bearing (8) is rigidly mounted on a rotor shaft (6) while being axially slidably received in a stator bore. A spring (44) biases the outer race (14) of the bearing axially outwardly of the bore, while adjustment screw means (46) in a rigid bore cover (34) are operable to displace the outer bearing race inwardly, thereby enabling a fine axial adjustment and separation of the rotor from a position in which an end surface (24) of the rotor is in engagement with a cooperating internal stator wall portion (26) to a position in which the gap is of predetermined small size eg 50-70  mu m. <IMAGE>
Patent GB-2174562-A (GB)
Title: Fluid conductivity sensing circuit
Inventor: MILLER FRANCIS M
IPC: G01N27/06
Filed: 1986-06-16
Abstract: The circuit can be used to detonate an electro explosive device 86 for operating a release mechanism for uncoupling a parachute canopy from its load upon landing in water. An SCR 60 is turned on to charge an ignition capacitor 64 when a conductivity sensing circuit 70,72,74,78 senses the conductivity between electrodes 24,34 and the rate of change of conductivity to be above certain levels. A voltage independent portion of an operating network turns on an SCR 90 after a time delay from the start of charging of capacitor 64, which delay is independent of the rate of voltage rise on capacitor 64. The SCR 90 discharges the capacitor 64 through the device 86 to activate it. The operating network also has a voltage dependent portion which, when a voltage of predetermined magnitude is developed on the conductivity sensing circuit in response to fluid not having the predetermined condition of conductivity, turns on SCR 90 to define the discharge path through the device 86 when the energy in capacitor 64 is insufficient to detonate the electro explosive device. A regulated current source 78 is connected in relation to the conductivity sensing circuit and to the electrodes 24,34 in a manner placing the battery voltage 46 across the electrodes when the conductivity is below a predetermined magnitude so that the sensing circuit does not respond thereto and placing the battery voltage 46 across the sensing circuit when the conductivity is greater than a predetermined magnitude. The electrodes 24,34 are of dissimilar metals so selected and connected relative to the polarity portions of the circuit to maximise utilization of the battery output voltage. <IMAGE>

Title: Container and lid
Inventor: HAINES PETER REGINALD
IPC: B65D43/02
Filed: 1986-10-17
Abstract: A container assembly comprises a plastics containers with a cylindrical side wall 1 carrying an internal annular catch 6, and a circular plastics lid 2. The lid has an annular channel 7 in its edge part and an external annular rib 14 which forms an annular recess 15 with the outer edge 8 of the lid. An annular bead 12 on the lid indicates where pressure is applied during fitting of the lid so that, when the edge 8 of the lid abuts the catch 6, a bending moment is applied at A-B to the material of the lid causing the recess 15 to open and the rib 14 to engage over the catch 6. When the pressure is removed the recess 15 closes over the catch 6 to form a seal therewith. The assembly is suitable for containing fluid such as paint. <IMAGE>

Title: Automatic focus and exposure controlled camera
Inventor: RASCHKE KLAUS
IPC: G03B7/085
Filed: 1986-11-17
Abstract: An electrically operated camera has an automatically operated lens focusing system including a focus control ring (40) which varies the position of a lens, cell assembly (42) along the optic axis between far-focus and near-focus lens settings responsively to ambient light sensings. The far-focus lens setting is less than infinity. Under strong lighting conditions, the aperture is automatically set between a range of values. In weak light, a flash system (3) is automatically enabled, the lens is set to a near-focus position, and the aperture is automatically arrested at its minimum value. Timed energization of a single electrically operated solenoid (72) is used to establish all settings in both modes. An additional macrofocus setting is provided for setting the lens (42) at a focusing distance much shorter than the near-focus setting, and the aperture is automatically set at its minimum value in flash mode, or over a range of values according to ambient sensings when bright lighting conditions prevail. <IMAGE>

Inventor: CLIFT MICHAEL
IPC: F16K31/06
Filed: 1987-04-23
Abstract: The solenoid-operated valve comprises a coil (25) operating an armature (26) carrying a shaft (30). A body (31) has a cavity (34) which houses the coil and armature, and has an opening (32) through which the shaft passes. A valve head (20) is carried on the free end of the shaft.

Title: Stoves
Inventor: WITTERS IAN HAMISH
IPC: F24B9/04
Filed: 1987-08-07
Abstract: A stove has a body which houses a primary burning chamber (10) and a secondary burning chamber (12).

Patent GB-2202021-A (GB)
Title: Safety joint for pipe lines and flow lines
Inventor: ASBURY ANTHONY JOHN
IPC: F16L37/00
Filed: 1987-11-25
Abstract: A safety joint is provided for use in, for example, offshore oil and gas pipe line systems which includes male and female pieces which are arranged to part under a predetermined axial load. The male piece (1) includes a number of pressure-balance units each of which comprises a piston (5) movable with a radially outward component to urge a release member (9) into engagement with an inwardly extending flange (33) on the female piece (2). The piston (5) and release member (9) are arranged such that an outward force e.g. fluid pressure in the pipeline on the piston (5) tends to force a bearing surface on the release member (9) into engagement with a bearing surface (37) of the flange (33). The arrangement is such that a tensile load applied to the safety joint over a predetermined amount causes the pressure applied by the flange (33) on the release member (9) to fracture a shear pin (7) to allow inward movement of the piston (5) and hence separation of the male and female pieces (1 and 2). For certain applications where pipeline pressure is not suitable e.g. multiple hose bundles, the piston may be driven by mechanical means (Figs. 2 and 3). The release member may take the form of rollers carried by the tension rod (10) (Fig. 7) or the piston (5) (Fig. 10). The shear pin (7) may hold the tension rod (10) (Figs. 8,9,10) or form part of the swivel linkage (11) (Fig. 13). The tension rod (10) may be replaced by a compression rod (Fig. 12). The movement of the piston (5) may have an axial component (Fig. 10). <IMAGE>

Title: Joining polyolefinic members by fusion
Inventor: DICKINSON ALAN JOHN
IPC: B29C65/52
Filed: 1988-02-19
Abstract: First and second members (e.g. pipes, fittings) of cross-linked polyolefinic material such as polyethylene having a melt flow index (MFI) of zero are joined using a third member of polyolefinic material such as polyethylene having a higher MFI e.g. 0.3. The first member 10 and the third member gripped by clamps 18, 20 of a butt fusion machine are pressed against opposite faces of a heater plate which is then withdrawn and the members are pressed together by the clamps. Only the third member is upset to form beads 24, 26. Part of the third member is removed leaving a stub part 16. The second member is joined to the stub's face 36 using the heater plate. The part 16 is upset leaving a thin wafer 48. The two interfaces 30, 50 limit the growth of cracks in the wafer to prevent their propagation through the pipe thickness under hoop stress. The beads are preferably removed at each stage.

Title: Orthopedic hinge
Inventor: BORIG DONALD ALLEN
IPC: A61F3/00
Filed: 1988-07-27
Abstract: An orthopedic device suitable for controlling hip joints is provided which includes a first hinge means (10, 22, 36) for flexion and extension of the hip and a second hinge means (20, 31) for abduction and adduction of the hip. The orthopedic hip hinge permits a shortening of the overall length of the hinge arm assembly during abduction of the hip and minimizes pistoning of the thigh attachment support. Also included are means for permitting free abduction of the orthopedic hinge within a specified range, while preventing any adduction of the hip. The disclosed device more closely approximates the actual motion of the femoral head in its socket, since the flexion hinge and the abduction hinge employ a common element, and are disposed in a ball-joint arrangement.
