Patent SE-330327-B (SE)
Inventor: HARVEY D
IPC: G03B15/04
Filed: 1966-07-11
Abstract: 1,154,172. Photographic cameras. EASTMAN KODAK CO. July 7, 1966 [July 12, 1965], No.30544/66. Heading G2A. A photographic camera having a socket for receiving flash-cubes and indexing means associated therewith for rotating the socket, is further provided with manually operable means movable from a first position in which indexing of the socket is prevented to a second position in which indexing of the socket is effected by the indexing means. In the embodiment shown, the socket and inserted flash-cube 5 are fixedly attached to a shaft 30 and movable therewith, the shaft 30 also carrying a segment 31 of a clutch mechanism. The other clutch segment 32 is slidable on a shaft 33, but rotates therewith, and bears against a manually operable lever 34 which, in its first position, maintains the segment 32 out of engagement with the segment 31. Rotation of the shaft 33 in response to film winding mechanism is therefore not transmitted to the shaft 30, so the socket is not indexed. However, a switch 39, controlled by the lever 34, is open, so a circuit to a flash-bulb of the inserted flash-cube is not completed. When it is desired to make a flash exposure, the lever 34 is rotated anti-clockwise (as seen) to a second position thereby closing the switch 39 and causing the segments 31, 32 to engage. Depression of the shutter release then results in a flash exposure, the flash-cube being indexed as the film is advanced, the relationship between the film advancing mechanism and the indexing mechanism being as described in Specification 1,154,171. In the embodiments of Figs.2, 3 (not shown) a sprocket wheel (9, 9<SP>1</SP>) is advanced through 90 degrees by a slip clutch mechanism as described in Specification 1,154,171. The manually operable means comprises a lever (11, 11<SP>1</SP>) which in its first position engages one of a series of projections (10) on the sprocket wheel and, on being pivoted to its second position, releases the projection and closes a switch (13, 23) in the flash-bulb circuit. In another embodiment Fig. 5 (not shown) a second shutter release button (42) is provided for use when making a flash exposure. Depression of this button not only actuates the shutter, but also closes a normally open switch (44) in the flashbulb circuit and pivots a lever (46) out of engagement with a slip clutch (48) to allow of indexing. In a further embodiment Fig. 6 (not shown), a second shutter release button (51) is again provided to actuate the shutter and close the flashbulb circuit which also contains an electromagnet. On depression of the button (51) current passes through the winding of the electromagnet and attracts a hooked lever (57) out of engagement with a sprocket wheel (58) which rotates under spring action to index the flash-cube during exposure.

Title: Apparatus and method for continuous casting of metallic strands at exceptionally high speeds using oscillating mold assembly
Inventor: GEORGE SHINOPULOS
IPC: B22D11/14
Filed: 1981-05-26
Abstract: An oscillating cooled mold assembly for the continuous high-speed casting of metallic strands, (12) especially upcasting strands of copper alloys such as brass, has a hollow die (112) in fluid communication with a melt (14) typically held in a casting furnace (16). coolerbody surrounds the die in a tight-fitting relationship to form a solidification front in the melt as it advances through the casting zone of the die. During assembly, the die is preferably slip fit in the coolerbody (103). A shoulder on the die engages a lower face of the coolerbody (103) and, together with a small irregularity on the upper coolerbody wall, prevents any axial movement of the die before it thermally expands against the coolerbody. An insulating member (118) located between the die and the coolerbody and below the solidification front fixes the location of the front within a dimensionally uniform area of the die. The insulating member is preferably a ring of a material such as casting silica that has a low coefficient of thermal expansion, a low porosity, and is highly resistant to thermal shock. The insulating member (118) also preferably creates a steep longitudinal temperature gradient at its upper end to promote a high cooling rate over a relatively short casting zone. An insulating hat encloses the coolerbody, allowing it to be immersed in the melt and preferably deeply immersed to a level above the casting zone The strand or rod formed from the solidified melt is pulled through the die while the mold oscillates in a direction substantially parallel to the direction of travel of the rod.

Title: Method and apparatus for epithermal neutron porosity well logging
Inventor: HERTZOG RUSSEL C
IPC: G01V5/10
Filed: 1991-04-04
Abstract: The porosities of subsurface earth formations surrounding a borehole are investigated using a logging tool run in the wellbore by repeatedly irradiating the formations with discrete bursts of high energy neutrons, measuring the populations of epithermal neutrons at near and far locations from the neutron source, and also measuring the rate of decay of the epithermal neutron population at a third location following each neutron burst and deriving therefrom a measurement of the epithermal neutron slowing down time. Formation porosity values derived from the near-and-far location population measurements are corrected for detector standoff effects by use, in accordance with a predetermined empirical relationship, of the epithermal slow down time measurement. Alternatively, formation porosities may be derived both from the near-and-far location measurements and from the epithermal slowing down time measurement, and the two differently-derived porosity values may be used independently to provide enhanced information of formation porosity or they may be compared to derive a standoff-corrected porosity value. <IMAGE>

Title: Methods for transmitting information to individuals and groups by exploiting locality factors whilst preserving user privacy
Inventor: ROSS GORDON
IPC: H04L29/08
Filed: 2000-01-25
Granted: 2003-04-16
Abstract: Developments in communications have increased the volume of traffic travelling over different circuits, including copper, fibre and wireless. The anarchic architecture of the Internet means problems of overload and slowness are likely to remain. Remedies have been found, including server caching and Internet accelerators, but these address symptoms not causes. Much of the traffic is unnecessary given what we know of human information processing. An alternative is presented. This method uses locality as a factor in determining routing, making it more predictable, shorter and faster than existing mechanisms. To preserve privacy the method hides locality cues within random and/or non-location specific addresses. The underlying geographic cues can be utilised for genuine purposes, but are not freely available. By hiding locality cues within the information substructure it gives additional degrees of anonymity and security to users, helping with both privacy issues and security so improving opportunities for electronic interaction and commerce.

Title: Soft bifocal contact lenses
IPC: G02C7/04
Filed: 1979-08-09
Granted: 1983-01-26
Abstract: A soil bifocal contact lens is made by mounting the concave back surface 15 of a lens blank 14 on the convex support surface 11 of a lens cutting lathe and cutting a first convex surface 18 on the front of the blank to produce a distance correction lens with a prismatic component. This can be done by offsetting the surface 11 to locate its centre of curvature 12 off the axis of rotation 13 of the lathe. The position of the lens is then adjusted to cut a second surface 23 in the thicker portion of the prismatic lens with the second surface 23 providing a near correction segment which has a prismatic component less than or of opposite sign to that of the distance lens. The blank is then hydrated to make it soft. In a preferred arrangement the distance and near correction lens portions are given equal and opposite prismatic components by rotating the lens by 180 DEG  relative to the support surface 11 before cutting the second surface 23. The lens may be truncated top and bottom and provided with a bottom ledge 31 for stabilising in the eye. <IMAGE>
