Abstract: 737,994. Non-refillable bottles. LESUEUR, F. H. July 23, 1951 [June 7, 1951], No. 13559/51. Class 125 (1). A closure for a non- refillable bottle comprises a tubular member 10 sealed in the neck 11 of a bottle and having a valve seating 14 at its inner end. The valve opening 14 is closed by a disc valve 17 attached to a spider body 15 having a convex central portion 18. A ball weight 29 is caged between the valve body 15 and an apertured partition 19 having a central depression 21 so that the valve is only able to open when the bottle is inverted sufficiently for the ball to enter the central depression 21. The partition 19 acts as a labyrinth baffle and has ridges 27, 28 to prevent tampering by a wire and may have a valve seating 24 in its outer end. A valve 25 coacts with the seating 24 and has a spigot 26 extending into the depression 21 so that on inverting the bottle the ball 29 assists in opening the valve. A pouring lip 31 has stops 32 to arrest the valve 25 and an additional labyrinth baffle may be provided in the outer end of the member 10. The parts are preferably of non-magnetic material.

Abstract: 1,099,566. Vacuum chucks. DUNHAM TOOL CO. Inc. March 28, 1966 [April 6, 1965], No. 13659/66. Heading B3D. A rotatable vacuum chuck comprises a rotatable vacuum chamber adapted to be connected to a source of vacuum and rotated about a predetermined axis, plate means which is porous and is adapted to have part of its surface selectively closed off or has a plurality of ports which can be closed by plugs, the plate means being mounted in communication with the chamber, and adjustable stop means arranged about the plate for aligning a workpiece therewith and to restrain the workpiece against radial displacement. The vacuum chamber consists of a network of channels 28 formed in a housing 10 having a threaded shank portion for attachment to a lathe or like machine, the portion having a bore 37 for connecting a source of vacuum to the chamber. In one embodiment, the plate means 11 has a plurality of circles of shouldered ports 15 each of which communicates with the network of channels 28 and can be closed by a shouldered screw having an 0-ring for abutting the shoulder of the post. Each screw also has a passage which, when the screw is partially backed out, connects the port to the source of vacuum. When a workpiece P is placed on the plate 11, those posts not covered by the workpiece are sealed by the screws so that the vacuum only acts at the ports covered by the workpiece. At least three eccentric stops 12 are provided at the periphery of the plate 11 and can be adjusted and secured by screws 34 so as to abut-and retain the workpieee from radial displacement. In an alternative embodiment, the plate is fabricated from a porous material which may be masked with a removable non- porous material having an aperture conforming to the shape of the workpiece in the manner described in Specification 1,069,138, and the edge of the workpieee is abutted by the eccentric stops.

Title: Handling of carbonaceous solids
IPC: C10B49/22
Filed: 1947-05-23
Abstract: 629,696. Distilling or gasifying solid carbonaceous materials. STANDARD OIL DEVELOPMENT CO. May 23, 1947, No. 13910. Convention date, Nov. 22, 1946. [Class 55 (i)] [Also in Group XIII] In a carbonisation or gasification process using the fluid solids technique, wet material such as raw coal is dried prior to entering the carbonisation or gasification zone by mixing with dry material which has a temperature above the boiling point of water at the prevailing pressure. The wet coal enters a line 3 and meets hot dry coke supplied from the carbonisation chamber 20, the mixture falling into a standpipe 5 where dry fluidizing gases are supplied through a line 7, the mixture assuming a temperature between 150‹ and 300‹ F. The solids in the chamber 20 are withdrawn through a pipe 31 and a conveyor 37, an elevator 39 discharging a proportion of the hot dry coke into line 3 to mix with the incoming raw coal. Air or oxygen is supplied to the chamber 20 from a line 11 through a flow controller 17 and volatile carbonisation products pass off through a cyclone separator 25. The solids flow through standpipe 5 is controlled by a thermocouple 41 arranged in carbonisation zone 23 to maintain a carbonising temperature of 800-1,200‹ F. for a given flow of air or oxygen and the solids flow through pipe 31 is regulated by level responsive means 43 actuated by the level L20.

Title: Method and apparatus for producing  copying sets
IPC: B41L1/02
Filed: 1972-03-24
Abstract: 1390124 Feeding and collating sheets K SYROVATKA 24 March 1972 [26 March 1971] 13928/72 Heading B8R Writing-paper sheets are separated in turn from a plurality of piles at stations I-VI, Fig. 1, by fuction or pneumatic rollers A1 and fed by rollers A2, A3 to a belt A4, the rollers A1 being rotated at such times as to form on the belt an overlapping or non-overlapping stream of sheets comprising one from each pile. Each sheet is registered at B and then fed by rollers C to a numbering and perforating cylinder D1, where a transverse line of perforations is formed, and thence to a point X. Meanwhile, carbon paper is fed from a roll H, cut into sheets by cutters J, and the sheets fed by a belt J1 to a device K which produces a line of glue or paste on both sides, and thence to the point X. One writing sheet and one carbon sheet occurs at X together and are attached together by the glue and then deposited on a plate G where it becomes similarly attached to a preceding sheet pair, so that finally a copying set is formed of six writing sheets with interleaved carbon sheets all attached together along a transverse line near one edge. At each station there is provided a photo-electric sensor comprising a light or infra-red radiation source A5, Fig. 2, and a receiver A6. In normal operation, when a sheet reaches the light flash, the reduced light intensity at the receiver A6 de-energizes a relay R to stop the roller A1 by means of an electro-magnetic coupling VK, Figs. 2 and 3. The light intensity of the source A5 is then increased so that the relay is reenergized so that the sheet is fed onwards. If double feed has occurred, the relay R is not registered, and by a contact R<SP>1</SP> a defect lamp L is lighted and the machine stopped, while if no sheet is fed, failure of the relay to be deenergized has the same effect. The switches U controlling the machine stoppage in conjunction with the contact R<SP>1</SP> are controlled by cams on a shaft StW. The number of stations may be other than six, and the speed of the camshaft is modified accordingly. Similar sensors may be used to detect correct alignment at B or of the carbon sheets after cutting.
