Title: Apparatus for the successive display of a series of dioramas and dioramas utilized in the apparatus
IPC: A63J13/00
Filed: 1937-06-18
Abstract: 474,966. Changing signs. CARRE, P. A. J., and CARRE, J. L. A. M. June 18, 1937, No. 17012. Convention date, June 18, 1936. [Class 3 (i)] In apparatus in which a plurality of independent display elements travel in a closed circuit for successive positioning at a viewing aperture, the ' elements comprise collapsable panoramic structures 9a . . . 9f, 10 which are stored in a collapsed state in a lower compartment 7 of a casing 1 and are raised in turn into an upper compartment 8 where they are expanded for display and then collapsed for transfer below. Each structure 9a &c. consists of a front apertured panel 11 connected to a rear panel 12 by bellows 13, cross braces, or other extensible means, intermediate scenic &c. sheets being arranged between the panels 11, 12 if required. The front panel 11 carries hooks 14 which are engaged by pins 22 on two parallel endless chains 21 travelling round sprockets 15 ... 20. The pins 22 when rising from the sprockets 15 first lift the end structure 9a into the compartment 8, and then, travelling horizontally, move the panel 12 forward. On each side of the compartment 8 are two springs 24 holding between them a vertical rod 25 which engages with and detains the rear panel 12, the springs 24 entering slots in the panel sides. The structure 9a is thus expanded, and the advancing panel 11 first releases the rear panel of the structure last shown by splaying apart the springs 24 and then collapses same till on clearing the front edge of base 5 it falls by gravity on to cushioning springs 27 and a pad 38. It is then pushed, by contact of the descending pins 22 with its panel 11 and the rearward movement of said pins caused by the chains 21 passing round sprockets 18 and 19, till spring hooks 28 take over its front panel and hold same in situ. A spring-roller blind 29 may be provided to hide the structures during change of display, the blind rod having depending hooks 31 which are engaged by outward projecting pins 33 on the chains 21 and brought down till they take under spring-pressed hooks 34. The blind is released to fly up again by the pins 33 kicking away the tails 35 of the hooks 34. Fig. 4 shows a modification in which the panels 11, 12 rise into guide-ways 40, 41, the guide-ways 40 being connected both to the guide-ways 41 and to the casing back by springs 44, 43. Hooks 45 hold back the panel 12, while the guide-ways 40 move forward on slides, under the action of the pins 22, Fig. 1, to extend the structure, the guide-ways 40 snapping under springs 26. Lugs on the chain then force apart the hooks 45 to release the panel 12 and allow the springs 44 to pull it forward to position 41a. After the structure has dropped, lugs on the chain force away the hooks 26 to allow the springs 43 to bring back the guide-ways 40, 41 to their initial position.

Title: Improvements in or relating to the production of lubricating oil
IPC: C10G73/06
Filed: 1932-06-18
Abstract: A treatment auxiliary to the process of dewaxing mineral oil by chilling a solution of the oil to 0 DEG  -- minus 70 DEG  F. and centrifuging, consists in adding finely divided solids to a solution of the oil, and filtering the mixture at a temperature, e.g. 50--75 DEG  F. low enough to form a cloud other than that due to the added solids, but high enough to prevent precipitation of amorphous wax. Neutral solids such as kieselguhr, sawdust, or paper pulp may be used in proportions of \ba1/4\be--1 lb. per gallon of oil, or if clay has been used in the previous refining of the oil (e.g. for removing asphalt, decolorising, or neutralising after acid treatment) a solvent for the oil may be added, and the clay removed by filtering at the specified temperature.  Naphtha and gas oil are suitable solvents for the oil.  The mixture of oil, solvent, and finely divided solid may be heated, e.g. to 90--110 DEG  F. to bring all the wax into solution, and then cooled slowly, e.g. 2 DEG  or 3 DEG  F. per hour, to the filtering temperature.

Abstract: An oestrogen preparation comprises a rigid solid solution of an oestrogen in a water-soluble or water-miscible substance which is rigid solid at 20 DEG  C. and is capable of precipitating the oestrogen in a finely divided form on contact with an aqueous medium. Examples of the latter are polyethylene glycols (4000 or 6000), polyoxyethylene esters or ethers, polyoxyethylene sorbitan esters, and mixtures thereof.  One part of oestrogen is used for every 5 to 50 parts of the water-soluble solid.  The term "oestrogen" covers natural and synthetic oestrogens and substances having an oestrogen-like action, e.g. oestradiol, stilboestrol, oestrone, oestriol, dienoestrol, ethinyloestradiol, hexoestral, chlorotrianisene or methallenoestril, or an ester thereof, or a mixture of these substances.  The solid solution is obtained by rapidly cooling a molten solution of the oestrogen in the water-soluble or water-miscible substance, e.g. by pouring into a pan which is at room temperature.  The preparation may be powdered and compressed into pessaries along with suitable adjuvants.  The pessary may be made effervescent by incorporating therein an alkaline carbonate or bicarbonate and an organic acid such as citric and tartaric acid antibiotics such as framycetin, polymyxin or streptomycin may be incorporated in the pessaries.

Title: Improvements in or relating to the production of sintered compacts of beryllia
Inventor: MURRAY PETER
IPC: C04B35/08
Filed: 1958-06-02
Abstract: Pure calcined beryllia powder is cold-compacted, and then heated to a temperature not higher than 1400 DEG C. and for such a period that substantially all the particles are welded together, after which the compact is heated to at least 1500 DEG C.  The first heating step is preferably carried out at a temperature in the region of, but not less than, the temperature at which the beryllia was originally calcined.  For example, if the calcination were at about 1250 DEG C., the first heating should be from 1250 DEG C. to 1400 DEG C.  In another case, a beryllia powder calcined at 900 DEG C. was cold compacted, and heated for at least 40 hours between 1100 DEG C. and 1400 DEG C.  The heating to a sintering temperature of at least 1500 DEG C. may be carried out continuously or in stages.  The calcined beryllia powder may be produced by treating suitable beryllium compounds, for example the hydroxide, carbonate, or oxalate to 500 DEG C.-1400 DEG C.

Title: Improvements in or relating to tyre building machines
IPC: B29D30/32
Filed: 1960-05-19
Abstract: 947,182. Tyre building machines. DUNLOP RUBBER CO. Ltd. May 19, 1960 [May 22, 19591, No. 17634/60. Heading B7C. In a tyre building machine comprising a collapsible cylindrical building drum 2 with a bead setting and ply-turning device at each end, the ply-turning device includes a series of S-shaped springs 16 pivotally arranged at one end 15 on a common pitch circle coaxial with the drum and radially within the building surface thereof, the springs being urged radially inwardly about their pivots by a rubber band 17 encircling the springs in the first bight portions thereof, and the springs are movable from a position within the drum as shown in Fig. 3, axially outwardly to engage the turned down edges 41 of the carcase plus 40 and be forced thereby to pivot radially outwardly and thus effect ply turn-up as shown in Fig. 4. The radially outward pivoting of the springs 16 may be assisted by inflation of a rubber annulus 18 encircled by a coiled leaf spring 20 which normally supports the radially inwardlyurged bight portions of the springs. As shown in Figs. 7 and 8, to effect ply turn under of subsequent plies the springs are first pivoted radially outwardly by inflation of the annulus 18 and then moved axially from outside the drum, Fig. 7, to a position therewithin, Fig. 8, the springs being caused to pivot radially inwardly in so moving by contact with the ply ends and the tyre bead, the annulus 18 being deflated to permit such pivoting. As shown, the springs 16 and the supporting inflatable annulus 18 are carried by an extension 13 of a sleeve 11 slidable axially on a further sleeve 22 which is slidable along the drum shaft 1a and supports the bead-setting device. The bead-setting device comprises a disc 3a radiating from the sleeve 22 and carrying at its outer periphery an annular doubleacting pneumatic piston and cylinder arrangement, the cylinder 23, 27, 26, 26a of which carries a bead-holding shoulder 24 at its end adjacent the drum 2. The piston 8, 8a, 8b carries a circular series of leaf springs 9 each terminating in a roller 10 and a further circular series of leaf springs 12 are pivoted on a flange 31 of the sleeve 11 and encircled by a rubber band 34 to bias the springs 12 into the position shown in Fig. 1. In operation, the sleeve 22 is moved axially towards the drum carrying with it the sleeve 11 until the latter is stopped by means (not shown) engaging the extension 13, whereupon the sleeve 22 continues so that the shoulder 24 forces the springs 12 radially inwardly to effect initial ply turn down ready for application of the bead 21 on the shoulder 24 to the drum end. In this position air is introduced into the cylinder chamber 27a to extend the piston 8 so that the rollers 10 stitch the bead filler strip 30 to the plies, Fig. 3. Thereafter, the piston 8 is retracted, and then the sleeve 22 is retracted to bring stop-pins 35, 36 thereon into engagement with the flange 31 of sleeve 11 and thereby effect the axially outer movement of the springs 16 necessary for ply turn-up, Fig. 4.
