Title: Improvements in and relating to bottles and particularly hot water bottles
IPC: A61F7/08
Filed: 1946-03-13
Abstract: 626,853. Stoppers. ATKIN, D. March 13, 1946, No. 7881. [Class 125(iii)] Bottles, particularly hot water bottles and especially such as are made of rubber, are provided within the neck with at least one shallow flange or rib formed of elastic material extending circumferentially inward and adapted to be compressed or displaced by the introduction of a stopper and forming therewith a liquid tight joint, the efficiency of which will be increased by fluid pressure acting from within the bottle. Fig. 1 shows a construction having a plurality of shallow flanges 3, each having an undercut surface 4, whilst in Fig. 2, (not shown), there is only one flange of similar shape. Fig. 3 shows a modification in which a rib 16 on the stopper engages a recess between flanges 14 and 15 and a shoulder 17 on the stopper forces the lower flange 14 into the position shown. In Fig. 4, a rib 24 on the stopper engages a recess between flanges 20 and 22 in the neck, the lower flange 20 having a downwardly extending surface leaving the recess 21 into which the fluid may flow. In a further modification, Fig. 5, (not shown), a flange is so dimensioned that it is compressed by the stopper causing it to bulge. In Fig. 6, (not shown), a flange is of triangular section so that when the stopper is inserted, the flange is displaced downwardly, the fluid entering the space between the flange and the neck. Specification 465,355 is referred to.

IPC: G07F11/16
Filed: 1916-06-03
Abstract: 106,163. Asserson, B., and Miniature Automatic Syndicate. June 3, 1916. Delivery of articles stored in piles.- The lowest article of a vertical pile 30 is pushed out by the upwardly-projecting arm 36 of a spring-controlled slide 7 which works beneath a fixed base-plate 19; a lever 21 actuated by a pull-bar 25 serves to operate the slide by engaging a lug 20. A detent 14 is moved out of engagement with an aperture 14<a>, Fig. 5, in the slide by a pivoted plate 2 which is rocked on the insertion of a coin. A pivoted shutter 27 closing the delivery aperture is lifted by the issuing article, and, by means of a pin 31 engaging an inclined slot 32, lifts a second pivoted shutter 33. Coin-slit closing-devices; fraud, preventing.- The inserted coin rocks the pivoted plate 2 into the position shown in Fig. 5, so that its lip 4 passes under and closes the coin-insertion slot, a projection 11 on the plate simultaneously rocking a pivoted member 8 so that a projection 9 on that member also passes under the coin slot and co-operates with the lip 4 to prevent the insertion of a further coin or the operation by a wire. When the supply of goods is exhausted, one arm 39 of a weighted lever 38a moves into the goods receptable 29, the other arm 40 moving into engagement with a projection 41 on the member 8, so as to prevent the withdrawal of the projection 9 from beneath the coin slot. A projection 45 on a spring-controlled plate 44 working in a slot in the slide 7 engages the plate 2 and retains it in the displaced position when the slide is drawn out and the coin discharged. If a coin suspended by a string or other device is employed, a counterweighted detent 46 pivoted to the slide engages it during the return movement, so that complete return of the slide is prevented and the coin slot remains closed.

Title: Vapour phase cracking of hydrocarbons
IPC: C10G9/32
Filed: 1936-03-17
Abstract: <PICT:0461392/III/1> The process described in the parent Specification is modified to obtain products having a high aromatic content by passing heavy hydrocarbons in the vapour phase through reaction tubes maintained below 800 DEG  C., e.g. at 600--700 DEG C., at a space velocity exceeding the equivalent in vapour of three litres of liquid hydrocarbons per litre of reaction space per hour. Gas oil together with recycle stock is preheated in a heat exchanger 5 heated by waste gases from the cracking furnace and vaporized in a vaporizer 6. The vapours are passed through the preheating and cracking sections 2, 3 of the furnace and then cooled by passage through the heat-exchanger 5 and cooler 7.  Liquid products are separated in a separator 8 from gases and vapours which are passed to an absorber 10 where the gases are stripped with wash oil preferably similar to the charging stock.  The wash oil and the liquid from the separator 8 are mixed and flow through fractionating stills 9, 13, 14 from which gasoline, tar, and recycle stock are recovered.  The cracking tubes are constructed as described in the parent Specification.
