Title: A method of packing a receptacle with comminuted material
Inventor: SEAMAN PETER HERBERT
IPC: B01D61/48
Filed: 1960-05-13
Abstract: <PICT:0942762/C3/1> A receptacle such as an electro-dialysis cell having deformable walls is packed with ion-exchange resin powdered material under pressure, by supporting the permeable membrane walls during the pressure loading and then removing the support.  The support may be in the form of a rigid plate applied outside, or a pressure of gas.  The powdered resin may be supplied under air pressure in which the resin is entrained, or supplied as a slurry under water pressure.  The powdered resin can be pumped into the cell in a dry, humidity controlled, or wet state, or in the form of a slurry, for example to an assembly of glass base plate 24, polyethylene sheet 23, membranes 25, 29, gaskets 26, 28, separator 27 and on top a sheet of polyethylene 30 and metal or plastic plate 31, which support the diaphragms, and are all clamped together.  The slurry of resin is fed in under pressure, and excess water escapes through the normal flow passages.  The body is then frozen, the resulting ice cementing the particles together, after which the top plate and sheet 30 are removed, and a second cell assembled thereon, the top plates clamped on and the process repeated.  Specification 893.051 is referred to.

Patent GB-515851-A (GB)
Title: Improvements in thermally-operated electric switches
IPC: H01H5/02
Filed: 1938-06-14
Abstract: 515,851. Thermal switches. RAMSEY, A. R. J. (Automatic Control Corporation). June 14, 1938, No. 17658..[Class 38 (v)] In a thermal switch, a lever is acted on by a diaphragm through an intermediate member, the resilience of the lever in conjunction with a snap action arrangement causing the switch to operate with a temperature differential. The fluid pressure from a bulb is transmitted through a capillary tube 33 to the space between a flexible diaphragm 29 and a casing 30, to which it is welded at 31. Movement of the diaphragm 29 pushes a stud 24 against a spring 37 and carries with it a lever 50 pivoted at 52, which lever is held by the pressure of a spring 54 against a sleeve 41 of a setting knob 44 both of which are carried by the stud 24. Rotation of knob 44, which carries a dial 43 co-operating with a pointer 45, moves the lever 50 relative to the stud and varies its pressure on another lever 56 which comprises an insulating part 58 joining one conducting part 59 carrying contacts 68 to another part 56 pivoted at 61 about a point on a frame 21 inside a case 23. A spring 63 urges the lever 61 in a clockwise direction, so that contact 68 engages a fixed contact 80 on a resilient member having two limbs 76 and 79 connected by an upturned part 78 which bends as the contacts separate. With increase in temperature, the pressure of the diaphragm acts on the lever 56 which moves with a snap action to carry contact 68 from contact 80 to contact 83 when an armature 70 leaves engagement with a horseshoe magnet 72. With decreasing temperature the spring 63 moves the contact lever back with a snap action when an armature 69 leaves the magnet 72, the arrangement providing a differential between the higher and lower operating temperatures. Instead of a magnet snap action, a spring snap action as shown in Fig. 9 may be used. A bowed spring 111 exerts a force between notches in a support 102 and a channel shaped element 107 which it urges to rotate about a pivot 109 in an anti-clockwise direction against a screw 101 carried by the lever 59. Snap opening of contacts 115 and 121 is produced by the moment of the spring force decreasing as the force of lever 59 increases and rotates the member 107 in a clockwise direction.

Powder separated from a rotary gas flow in a chamber, e.g. a cyclone 1, Fig. 1, having outlets 3, 4 for the separate discharge of powder and gas, is transferred from the chamber to a pneumatic conveyer plant by means of a carrier gas which is prevented from mixing with the gas in the centrifuge by being fed through a vortex chamber 7 disposed in the conveyer plant coaxially underneath, and in unobstructed connection with, the powder outlet 3 and provided at different levels with tangential inlet 6 and outlet 5 for the carrier gas. In operation the gas vortex from the cyclone 1 extends down into the chamber 7 where it is surrounded by a vortex of the carrier gas. The velocity and inlet pressure of the carrier gas are adjusted by means of a throttle valve 8 so that no difference in pressure occurs at the interface of the vortices whereby no mixing occurs between the gases and the powder particles are transferred by centrifugal force from the inner to the outer vortex and out of the chamber into the conveyer line. In Fig. 3, the chamber 12 constitutes a reaction or drying chamber into which the powder is introduced at 11 in solution or suspension in a liquid which it atomized through one or more atomizers 13. A drying or reaction gas is introduced at 14 to a ring chamber 15 from which it is directed to the interior of the chamber 12. A gas outlet is provided at 17.
