PRESSES

B 30 B

PRESSES IN GENERAL (producing ultra-high pressure or ultra-high pressure and high temperature to effect modifications of a substance, e.g. for making artificial diamonds B 01 J 3/00) [2]

Note

This subclass covers:

–

presses in general;

–

those presses, for particular purposes, which are not provided for elsewhere.

Presses, using a press ram, characterised by the features of the drive therefor, pressure being transmitted directly, or through simple thrust or tension members only, to the press ram or platen

by lever mechanism (by toggle mechanism B 30 B 1/10)

operated by hand or foot

operated by cams, eccentrics, or cranks

operated by fluid-pressure means

by toggle mechanism

operated by hand or foot

operated by cams, eccentrics, or cranks

operated by fluid-pressure means

by screw means

driven by hand

driven through friction disc means

operated by fluid-pressure means [2]

by rack-and-pinion means

by cams, eccentrics, or cranks

the cam, crank, or eccentric being disposed below the lower platen or table and operating to pull down the upper platen or slide

by the pull of chains or ropes

by plungers under fluid pressure

involving a plurality of plungers acting on the platen (gas operated B 30 B 1/38)

having telescoping plungers (gas operated B 30 B 1/38)

wherein the plungers are operated by pressure of a gas, e.g. steam, air

by wedge means

by magnetic means, e.g. electromagnetic [2]

Presses characterised by the use of rotary pressing members, e.g. rollers, rings, discs

co-operating with a fixed member

co-operating with one another, e.g. with co-operating cones

arranged one within another, e.g. with a roller disposed within a rotating ring and co-operating with the inner surface thereof

Presses characterised by the use of pressing means other than those mentioned in the preceding groups

wherein the pressing means is in the form of a flexible element, e.g. diaphragm, urged by fluid pressure [2]

wherein the pressing means is in the form of an endless band

co-operating with another endless band

Presses characterised by a particular arrangement of the pressing members

having several platens arranged one above the other

wherein pressing is effected in different directions simultaneously or in turn

Presses specially adapted for particular purposes

for squeezing-out liquid from liquid-containing material, e.g. juice from fruits, oil from oil-containing material (kitchen equipment A 47 J; filtering, e.g. straining solids from liquids, using presses in combination with filtering elements B 01 D; expelling water from textile fabrics or laundry D 06 C, D 06 F; drying F 26)

using press rams

co-operating with permeable casings or strainers

co-operating with a rotary casing

without use of a casing

using pressing worms or screws co-operating with a permeable casing

operating with only one screw or worm

operating with two or more screws or worms

with means for adjusting the outlet for the solid

using rotary pressing members, other than worms or screws, e.g. rollers, rings, discs

using a flexible element, e.g. diaphragm, urged by fluid pressure (connection of valves to inflatable elastic bodies B 60 C 29/00) [3]

using an endless pressing band

Permeable casings or strainers

co-operating with a fixed mould

11/

each charge of the material being compressed against the previously formed body

11/

co-operating with moulds carried by a turn-table

11/

intermittently rotated

11/

co-operating with moulds on the circumference of a rotating drum

11/

co-operating with moulds on a movable carrier other than a turn-table or a rotating drum

11/

using pocketed rollers, e.g. two co-operating pocketed rollers

11/

using profiled rollers

11/

Roller-and-ring machines, i.e. with roller disposed within a ring and co-operating with the inner surface of the ring
