Title: Improvements relating to seats, especially for vehicles
IPC: B60N2/06
Filed: 1938-02-03
Abstract: 507,678. Vehicle seats. CHAPMAN, A. W. Feb. 3, 1938, No. 3464. [Class 52 (ii)] In a vehicle seat of the type attached to a wall or bulkhead and adjustable for height, the seat supporting structure comprises vertical slides 14 of channel section engaged with guide rails 10 fixed to the wall &c., and channel section bracket members 19 of substantially L-shape, the vertical limbs of the brackets embracing and being attached to the slides, and the other limbs extending outwardly to support the seat. The fixed rails 10 are of channel section with the edges turned inwardly, and the slides 14 have their edges turned over as shown in Fig. 4, over short lengths near their ends to engage the rails 10. Gaps 13A, Fig. 1, in the edges of the rails 10 permit disengagement when required. Secured to the slides 14 by bolts 17 and stirrups 17A, are the vertical limbs 18 of the brackets ]9, which are of channel section with the open side disposed rearwardly and downwardly. Reinforcing plates 21 are secured to the brackets 19 at the bends and to a cross-member 23 which is secured to the slides 14. Vertical adjustment is effected by screw mechanism including a screwed rod 25 supported from a lug on a member 27 fixed to the rails 10, and a nut housed in a casing 28 on the member '23 and operated by worm and wheel gearing from a handle 30. The seat frame is slidable horizontally, and the shaft 31 of the handle is of square section and slides in a hollow shaft 29. The seat proper is carried by a pair of L-shaped members 34 of channel section connected by cross-members. The lower limbs of the members 34 slide on the horizontal parts of the brackets 19, lugs 38 with turned up edges being provided to prevent vertical disengagement. Horizontal adjustment of the seat is effected by a screw journalled in a plate 41 on the seat frame and passing through a nut fixed to the member 19. The back-rest 43 is attached to the members 34 by bolts passing through rubber bushes 47.

Filed: 1969-02-20
Abstract: 1299192 Reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 9 Feb 1970 [20 Feb 1969 23 Jan 1970] 49999/69 and 3515/70 Heading G6C In a sodium-cooled fast reactor, a multiplicity of gas-pressurized containers 13 are immersed in the liquid metal and arranged to collapse on occurrence of an accident involving generation of sodium vapour and shock waves, Thus, the primary containment vessel 1 (which may be of spherical form, not shown), is protected against excess pressure. The gas within the containers 13, which may be of stainless steel, is the same as that of the gas blanket above the sodium surfaces. End closures 16 of the containers may be weaker than their bodies 15 so as to fail first. Sodium is circulated by pump 7 to a header 11 below the core; from the latter the sodium passes to heat exchangers 6 from which it re-enters the vessel 1 between its wall and a casing 4 for the core and heat exchangers.

Title: Improvements relating to methods of and apparatus for burning cement, lime, ores and the like
Inventor: LARSEN PETER
IPC: F27B7/40
Filed: 1954-02-08
Abstract: <PICT:0789963/III/1> <PICT:0789963/III/2> Lime to be burned is formed into nodules as in Specification 789,964, [Group II], and are preheated by passage through a gas or right-angles to the flow.  The average diameter of the nodules does not exceed 2 mms.  In operation, the nodules pass from a hopper 10 through a pipe 11 to the bottom of a pipe 3, whence the larger nodules pass into the kiln whilst the smaller ones are carried up the pipe 3 and are separated in a cyclone 4, from which they pass, via pipe 13, to the kiln.  Externally, the kiln carries a number of chambers 14 communicating with the kiln interior through curved ducts 15.  As the kiln rotates nodules enter the chambers at their lowermost position and are poured out at their uppermost position, thereby falling transversely across the hot gas stream.  Specification 343,513, [Group XII], also is referred to.

Title: Improvements relating to electro-magnetic mechanism for railway signalling and the like
IPC: H01H51/22
Filed: 1924-02-14
Abstract: 233,070. Roberts, W. S., and Railway Signal Co., Ltd. Feb. 14, 1924. Interlocking and controlling and locking.-An electromagnetically actuated locking-device or contact-making device comprises a permanent magnet system including four bar-magnets 1, 2, 3, 4 and a polarizing coil having a core and pole extensions 9, 10. At each end of the device, a pivoted member carries arc-shaped magnetizable members 17, 18 and a locking-piece 23. Energization of the coil by currents of opposite directions reverses the polarity of the pole-pieces 9, 10 and causes one pivoted element to move to the free position whilst the other is urged to the locking position. Contact making devices may be added on the pivoted members to coact with fixed contact fingers.

Abstract: 1,083,363. Electro-static developing apparatus. HITACHI Ltd. Jan. 28, 1965 [Jan. 30, 1964], No. 3892/65. Headings G2H and G3R. Apparatus for dry powder development of electro-static images comprises a rotating magnetic brush 4 in contact with the surface of a moving web 14 on which electro-static images are formed, and a rotating insulated brush 5 of fine metal wires on an insulated hub 7, the brush 5 being in deep intersection with the magnetic brush and mostly immersed in reservoir 9 of a developer powder consisting of a mixture of iron-powder carrier and a toner powder which may be a polymer derived from styrene and/or its homologues. Brush 4 is formed by ferrite permanent bar or arcuate magnets 1 on a non- magnetic hexagonal bar 3. The iron powder and toner are charged to opposite electro-static polarities by the rotation of brush 5 and are mutually attracted. Excess free toner is removed from the magnetically saturated brush 4, formed of iron powder, by brush 5. Fresh toner is supplied from store 10 in which it is agitated and charged by brushes 12 to prevent coagulation, and is fed in controlled amounts by brush 13 to reservoir 9. As shown, two intersecting brushes 5 are used with separate magnetic brushes 4. The level of toner is observed through the transparent wall of store 10. Image density control is carried out by measuring the light reflected from brush 4 with a transducer whose output is amplified and fed to a device which controls the speed of rotation of brushes 4 and 5.
