Title: Improvements in amusement devices
IPC: A63G7/00
Filed: 1925-07-27
Abstract: 250,802. Fairweather, H. G. C., (Maynes Corporation). July 27, 1925. Amusement apparatus.-An endless passenger carrier such as a conveyer passes through a tunnel structure 110, means being provided to give an undulating motion to each side of the conveyer independently. An undulating movement may also be imparted to the tunnel. A pair of driving pulleys 17, 18 are mounted at one end of the apparatus, and cables 24, 25 pass over these pulleys and a pair of pulleys 22, 23 at the other end of the apparatus. Idler pulleys 26 are located near the driving pulleys. Cross-bars 36 are clamped to the cables and support collapsable cars 27 which are provided with perforated bottoms. A motor 54 drives the pulleys 17, 18 through a clutch under the control of a handle 72, and also drives a shaft 91 running along the apparatus. Cross-shafts 98 are driven from the shaft 91 and are provided with cams 100, 101 and cranks 113 for giving reciprocating movements to cable supports 104 and tunnel supports 111 respectively. The cars are thus caused to follow an undulating path and to rock from side to side during their passage through the tunnel, while the tunnel is caused to undulate. The cars are brought to rest near the head 112 of an animal which the tunnel structure simulates and passengers enter by steps 120. As the conveyer takes the car into the tunnel, the upper jaw of the head 112 is closed by a crank 115 and a rod 114. When the next car appears, the conveyer is stopped bv a cam 80 on the pulley 17 striking a block 83 on the shaft 70 operated bv the handle 72 to throw the clutch out of engagement. At the same time a block 82 on the shaft causes positive stopping of the conveyer by engaging with a lug 81 on the pulley 17. At the discharge end of the apparatus, an attendant pulls a lever 122 to slide a platform against the car awaiting discharge so that the passengers may alight. A fan 130 blows air into the tunnel through the perforated bottoms of the cars.

Title: Improved apparatus for photographic developing
IPC: G03D5/06
Filed: 1927-07-18
Abstract: 298,965. Hall, B. J. July 18, 1927. Continuous apparatus for doveloping. - As the prints travel through the apparatus, they are rubbed by an impregnated developing roller whose peripheral speed is different from the speed of the prints. The apparatus in one form comprises a revolving drum A, Fig. 1, in contact with which rotate a feed roller B, a developing roller D, a damping roller or pad F which may be raised by hand or mechanically from contact with the drum, and removable absorption rollers E to remove surplus developer from the prints a'. The drum and all the rollers are covered with fabric. The developing roller D is gear-driven so as to rotate in the opposite direction to the drum A with a peripheral speed slightly greater or less than that of the drum. The remaining rollers are driven by frictional contact with the drum. The covering of the drum A may be flexible, and may be passed round an idle roller near the roller D to increase the area of contact with this roller. To this covering may be attached a raised celluloid strip between which and the covering 'the edges of the prints are gripped. Alternatively, the periphery of the drum may comprise peripherally sliding sections, between any adjacent pair of which a print may be gripped. When developing continuous lengths of prints, this function is performed by the damping roller or pad F. A small roller running at high speed contrary to that of the print may be mounted adjacent to the drum to detach and discharge the prints therefrom. Developer may be applied to the roller D by a squeegee inclined to the roller to form a trough into which the liquid is poured; or the idler may be hollow and perforated, with a tubular spindle through which liquid is introduced; or it may dip into a trough of developer, or rotate in contact with an idle roller which is in contact with a roller dipping into the trough. Additional idlers are used if more than one developer is required, or if the prints are to be intensified. In a modification,. the drum A is replaced by a travelling band working over a stationary table, and the band may be made in sections which open apart where the band passes round its driving rollers, but close together elsewhere, so that the edges of the print may be gripped between two sections. In another modification, the drum A is replaced by a reciprocating table L, Fig. 8, and the prints may be prevented from adhering to the rollers D, E, either in thisform or in the drum form of apparatus, by circular rings d' of longer diameter inserted in peripheral grooves in the rollers.

Patent GB-786301-A (GB)
Title: Production of olefin oxides
Filed: 1955-07-04
Abstract: An olefine oxide is produced by the direct oxidation of a corresponding olefine containing at least three carbon atoms which comprises introducing said olefine into a reaction zone comprising a water-immiscible organic solvent which is inert to oxygen at temperatures above about 130 DEG  C., passing an elemental-oxygen-containing gas through said solvent while said said solvent is held under pressure, maintaining said solvent at 130 DEG to 300 DEG  C. while said gas passes therethrough, maintaining in said solvent a sufficiently low concentration of at least one compound selected from olefine oxide, acids and water so as substantially to reduce the rate of hydrolysis of the olefine oxide, by withdrawing portions of the reaction mixture from the reactor, removing at least one compound selected from olefine oxide, acids and water from the portions of reaction mixture, and recycling the resultant stripped portions of reaction mixture to the reactor.  The preferred olefine is propylene, but butylenes, amylenes, hexylenes, heptylenes and octylenes may also be used. It is preferred to introduce into the reactor with the olefine a saturated hydrocarbon which in the case of propylene may be propane or butane.  Benzene is the preferred organic solvent but other solvents such as diphenyl may be used which are inert to oxygen and the olefine oxide and which will dissolve substantial concentrations of the olefine.  The quantity of olefine in the feed mixture is maintained at about 5 per cent of the solvent. Polymerization inhibitors such as nitrobenzene may be added to the reaction mixture in concentrations of about 10 per cent by weight of the solvent to improve the yields of olefine oxide obtained. The preferred catalyst is manganese propionate but other manganese salts or salts or oxides of other metals of variable valence may also be used.  The pressure during the process is preferably maintained above 300 pounds p.s.i.  On completion of the reaction the products are separated by known methods giving olefine oxides, glycols and appreciable amounts of organic acids.  In examples (1) and (4) propylene is oxidized with air using benzene as solvent and manganese propionate as catalyst with addition of byproducts from a previous similar oxidation, the reaction mixture is continuously withdrawn, propylene is flashed off, acids, water, propylene oxide and propylene glycol are removed, and the remaining solvent and by-products are returned to the reactor, propylene being fed in to maintain a constant concentration; after termination of the run the products are separated by known techniques giving propylene oxide, propylene glycol and organic acids; (2) a propylene-propane mixture is oxidized with air in the presence of benzene and manganese propionate, the reaction mixture being continuously withdrawn, extracted with sodium bicarbonate solution to neutralize acids, and recycled to the reactor; (3) a propylene-propane mixture is oxidized as in (1).
