Title: Improvements in and relating to cameras
IPC: G03B19/12
Filed: 1967-11-01
Abstract: 1,182,017. Single lens reflex cameras and shutters therefor. RICOH K.K. Nov.1, 1967 [Nov.10, 1966; Jan.13, 1967], No.49601/67. Heading G2A. A single lens reflex camera is provided with a pivotable mirror V and an extension for receiving the barrel of an interchangeable lens, a shutter mechanism being mounted on the extension behind an attached lens, there being inter-connection between the shutter driving mechanism and the mirror pivoting mechanism. When a film in the camera is advanced, a disc 8 is rotated in the direction shown and a pin 8a thereof engages abutment 25b to move a shutter charging lever VI to the left (as seen) thereby tensioning a spring 3. As the lever moves to the left, a shutter loading ring III is moved clockwise (as seen) by a pin on lever IIIb of the ring III engaging an extension 25a, until a hook 13a engages an extension IIc of a shutter control ring II, in which position the shutter blades IV are opened to their fullest extent. Depression of the camera shutter release button rotates a lever 14 so as to free the hook 13a from engagement with the extension IIc. This allows the lever VI to return to its initial position under spring action, the pin on the lever IIIb causing the ring III to move anticlockwise (as seen). The ring III carries the ring II with it. As the ring II rotates, a pin 19c of a lever 19 follows a cam surface IId of the ring II and thereby closes the shutter blades IV. Simultaneously a pin 12 of the ring II moves a rack 7 downwards so as to pivot (through linkage 4-6) the mirror upwards. Further rotation of the ring II causes an extension IIb to deflect a lever 18 thereby to free a shutter operating arm lever I to rotate under spring action and deflect the lever 19 so as to open the shutter blades for exposure, a diaphragm (not shown) having previously been set. As the lever I continues to rotate it deflects the lever 19 to close the shutter blades. An extension Ia of the lever I releases a hook 9 from engagement with the ring II which is then rotated clockwise back to its initial position, the pin 19c following the cam surface IId so as to open the shutter blades, and the pin 12 lowering the mirror.

Title: Improved adhesive compositions
Inventor: BARTH BRUCE PAUL
IPC: C09J111/00
Filed: 1964-12-09
Abstract: An adhesive composition comprises a chloroprene polymer, a rosin ester of a terpenephenol condensate, a polyvalent metal oxide and a solvent for the chloroprene polymer.  The rosin ester may be present in amounts of from 5 to 200 parts and the metal oxide from 1 to 32 parts, both per 100 polymer.  Specified chloroprene polymers are the homopolymers (preferred) and copolymers with such comonomers, as styrene, isoprene, acrylonitrile.  The rosin ester of the terpene-phenol condensate may be derived from a phenol having at least one active ortho- or para-position on the benzene ring, e.g. hydroxybenzene, cresol, xylenol chlorophenol, dichlorophenol, nitrophenol, catechol, resorcinol, hydroquinone, bis(p-hydroxyphenyl)methane, bis(p-hydroxyphenyl)ethane or 2,2-bis(p-hydroxyphenyl)propane, from a terpene hydrocarbon of formula C10H16 or a terpene alcohol, e.g. alpha-pinene, beta-pinene, dipentene, terpinene, limonene, 7-methyl-3-methylene-1,6-octadiene or terpenolene of from gum rosin, wood rosin or tall oil rosin.  Thus the ester may be a tall oil rosin ester of the alphapinene condensate of phenol.  The solvent may be an aromatic hydrocarbon, an aliphatic ketone, a chlorinated aliphatic hydrocarbon, or a lower aliphatic ester while the polyvalent metal oxide may be magnesium oxide and/or zinc oxide.  An additional compound derived from maleic or fumaric acid or maleic anhydride and the rosin ester of the terpenephenol condensate may also be present in amount up to 32 parts per 100 rosin.  Anti-oxidants, pigments and fillers are optional ingredients.

Abstract: 1,159,807. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 25 Nov., 1966 [26 Nov., 1965], No. 50475/65. Heading G6C. To reduce attrition between fuel pellets of a fluidized bed reactor the bed is fluidized by a coolant comprising an inert gas having dust particles entrained therein, the fluidized bed also containing granules of moderator material which are circulated in heat exchange with the coolant. As shown, helium gas coolant containing a suspension of carbon dust is driven by a circulator 5 into an inlet plenum 8 of the reactor and upwardly through a perforated plate 7 into a bed 15 of fuel pellets which is thereby fluidized, the bed 15 also containing carbon granules of a size intermediate between the carbon dust particles and the fuel pellets these granules serving as a moderator and reflector and being lifted by the gas stream so as to spill over the edge of a baffle 9 and descend through outer annular zone 11. Heat is removed from the granules in the zone 11 by the upward flowing of the coolant in that zone through the plate 7, the granules re-entering the bed 15 by passing through the plate 7. By altering the degree of fluidization the reactor may be controlled, greater changes being effected by absorber rods 12. Heat is removed from the coolant by circulating the latter through a manifold 2 to a heat exchanger 4. In a modification in which the reactor is used for the direct conversion of heat into electricity by magnetohydrodynamic principles the carbon dust particles are replaced by particles of thorium or thoria dust.

Title: An improvement in or relating to lubrication and cooling of journal bearings
IPC: F16N39/02
Filed: 1966-11-11
Abstract: 1,130,254. Bearings; lubricating gearing. RHEINSTAHL HUTTENWERKE A.G. 11 Nov., 1966 [13 Nov., 1965], No. 50768/66. Headings F2A and F2Q. In an arrangement for lubricating and cooling a journal bearing, a reservoir of oil lubricates the bearing and an overflow of oil from the reservoir cools the bearing. In an embodiment, a bearing 3 of a planet-gear 1 is provided with lubricating grooves 5, Fig. 1, and with peripheral cooling-grooves 6: and is mounted in a planet-carrier 4. The grooves 5 are fed with lubricant through a tube 10, a flared opening 9 of which collects oil from a rotating oil-collector channel 8, the latter being supplied with oil from an oil-feed conduit 7. Surplus oil from the tube 10 is passed through radial ports 11 therein into an annular duct 12 which surrounds the tube 10, and is conveyed, by means of a distributer-groove 13, to the cooling- grooves 6. The coolant oil is collected by a groove 14 and is passed to a gear-box through bores 15, in the planet-carrier 4. In another embodiment, an oil-feed conduit 16, Fig. 2, is rigidly connected to a planet-carrier 4 and throttling is provided at either a port 11 or at the outlet bores 15. In a modification, the planet-carrier 4 could be provided with an annular distribution groove and the peripheral cooling-grooves 6 in the bearing 3 could then be replaced by longitudinally-extending grooves. Thus the bores 15 in the planet-carrier 4 would be rendered unnecessary. In a further embodiment, a planet gear 17, Fig. 4, is rotatably mounted on a hollow shaft 20 by means of bushes 18. The shaft 20 is fixed in a planetcarrier 19; is provided with radial bores 24, which connect to lubricating-grooves 23; and has an overflow tube 25, which extends through the wall of the shaft 20 and projects a predetermined distance radially inwards of the shaft. Thus a segmental reservoir is formed in the shaft. In use, oil is supplied to the segmental reservoir from a feed-conduit 21 and a collector-trough 22; the oil is then centrifuged through the radial zones 24 and into the lubricating-grooves 23. When the reservoir overflows oil is passed through the tube 25 and into a chamber 26 which leads to cooling-ducts 27. In a modification, the ducts 27 are connected with radial bores leading to spaces between the gear-teeth.
