IPC: A47J45/06
Filed: 1950-11-21
Abstract: 692,315. Handles for hollow-ware; can closures. READS, Ltd., and GILES, A. J. Sept. 20, 1951 [Nov: 21, 1950], No. 28468/50. Classes 66 and 125(iii) A removable hoop-member constituting a locking-ring for securing a lid or closure plate on a container in known manner is provided with perforated lugs extending axially from it and a bail-handle whereof the ends are hook-shaped to be engaged with said lugs. The container 10 has a beaded rim 11 on which the lip 13 of a lid 12 is secured by means of a ring or hoop-member 15. A gasket 14 may be interposed between the rim 11 and lip 13. The ring 15 is divided at one point to enable it to be expanded and contracted as required and the two ends are locked by means such as a key 26 passing behind a tongue 16 on one end kinked to project through an opening in the other end. The ring 15 has lugs 17 welded thereto to accommodate the ends of a wire handle 18 which is secured by turning the ends 19 inwardly to form hooks. The handle is substantially semi-circular and lies closely to the wall of the container 10 when in transit or storage; it may have a rubber grip or a straight segment to receive a wooden grip 20. In use the ring_ 15 is released for removal of the lid 12 and is then replaced on the rim 11 in the reverse position so that the lugs 17 extend upwardly and the handle 18 is available as in Fig. 2. Alternatively the weight of the container may be taken directly by the handle by replacing the ring 15 below the rim 11, as in Fig. 3, such that the ends 19 of the handle bear against the underside of rim 11; or the ring 15 may be replaced as in Fig. 1, but with the lid 12 removed, the ends 19 again taking the weight directly. The handle may be permanently secured to the ring 15, or may be readily attachable thereto and packed separately for transport.

Abstract: 1430357 Soldering magnets BBC BROWN BOVERI & CO Ltd 27 June 1974 [29 June 1973] 28520/74 Heading B3R In a method of bonding together two or more RECo 5  permanent magnets 1, 1<SP>1</SP> and 2, RE denoting one. or more rare earth metals such as Sm or misch metal, layers of solder, e.g. in the form of foils 6, 6<SP>1</SP>, are applied to the surfaces 3, 4, 3<SP>1</SP>, 4<SP>1</SP> to be joined and the magnets are soldered together by heating in a gas tight furnace which is under vacuum or contains a protective gas atmosphere, i.e. one in which oxidation or other deterioration of the magnet is inhibited-such as Ar or He. The solder layers are preferably between 10 and 15 Á thick, protrude up to 4 mm. at the edges of the magnets and are hard solder such as copper and/or silver. The assembly of magnets and foils may be placed in a holder 8 comprising a steel frame 9 with a tantalum layer 10 and this is placed in a tantalum crucible 11 which is then inserted in a cooling zone 14 of the furnace 12 which is subsequently evacuated by pump 19. The protective gas may be introduced at 20 and the crucible &c. is moved into a heating zone 16 heated to a temperature from 100‹ to 0‹ C. below the melting temperature of the solder to effect soldering. After soldering the crucible is moved to the cooling zone for rapid cooling.

Title: Improvements in door securing means
IPC: E05B55/04
Filed: 1948-11-03
Abstract: 656,288. Door.locks. REED, G. F., and GOULD W. H. Nov. 3, 1948, No. 28609. Convention date, Nov. 7, 1947. [Class 44] A door lock comprises a spring shot bolt adapted to be retracted by a primary door handle having three positions : A normal unlocked position A, Fig. 2, where either handle may be operated to withdraw the bolt by movement to the position B, and a position C where the nose 34 of a catch on the handle engages in an opening 37 in the rose plate to lock both handles. The locked condition is thereby immediately apparent from the position of the handles. In the form of Fig. 1, the bolt 8 is withdrawn by a follower 27 mounted on a spindle 18 carrying a primary or inside handle 20 and a secondary or outside handle 19. The catch member, in the form of a spring urged lever 31 is pivoted at 36 in a slot in the back of the handle and carries the locking nose 34 on a rightangle arm. The nose is withdrawn from the opening 37 in the rose plate by finger pressure when the handle is grasped. The catch 31 can also be released from the outside of the door by a barrel lock 66 adapted, when released by the key, to be pressed in against a spring 77 to displace push rods 78, 86 bearing against the nose of the catch. The catch may be prevented from moving into the locking position by a disc 142, Fig. 3, rotatably mounted between the handle boss 22 and the rose plate 28, and operated by a tab 138. In the locked position the disc must be rotated so that an aperture therein registers with the opening in the rose plate, allowing the nose 34 to pass into the engaging position. In another form, Fig. 6, adapted for vehicle doors, the bolt 8 is connected by links 152, 157 to cranks 158, 150, mounted on the handles 18, 20. The inside handle 20 carries a sliding lock catch 31f, operated by the thumb of the hand grasping the handle through a serrated button 171. The rose plate has two openings 37f, 37g, Fig. 10, either or both of which may be covered by a disc 166 between the handle boss and rose plate. By this means the inside handle may be secured in the normal position (shown) where the latch is operable by the outside handle, this being permitted by lost motion at the slot 154 in the link 150, and in a locked position where the link is moved forward so that the rear end of the slot 154 engages the pin 153 preventing operation by the outside handle. The disc 166 is movable to four positions in which it is retained by a spring ball 172 engaging recesses in the disc. In a modification, Fig. 4, the catch takes the form of a lever 31e arranged to be released by direct pressure of the thumb of the hand grasping the handle. The neck of the catch works in an arcuate slot 163 and the catch nose 34e engages in one or two recesses 160 in the outer wall of the slot.

Title: Process and apparatus for heat-treating fluidized solids
Inventor: HEATH THOMAS DEMPSTER
IPC: F28C3/16
Filed: 1955-10-17
Abstract: Finely divided solids are heated in a process wherein a part of said solids is passed successively through at least three fluidized beds comprising a preheating zone, a heating zone and a final treatment zone, and the remaining portion <PICT:0787292/III/1> is passed directly from the preheating to the final zone: the heat supplied in the heating zone is greater than that required by the solid in the final zone which has passed thereto from the heating zone.  The process is described with reference to the treatment of haematite to form magnetite by reduction in the final stage.  A gas at 1100 DEG C. comprising H2, CO, CH4 and diluents was passed into the reduction stage which had a temperature of 650 DEG  C. whilst the heating zone was at 800 DEG  C. and the preheating zone at 220 DEG  C.; 54.3 per cent of the solids bypassed the heating stage.  In the illustrated embodiment, the preheating zone A is divided into two portions 30 and 31 by means of a partition 26, each of which is separately supplied with ore.  The ore is fluidized and preheated by the gases rising through grid 21 from the heating zone B and the ore in bed 30 is passed into the heating zone.  An inlet pipe 60 supplies air to the heating zone directly or through the upper part of chamber 45, whereby the combustible reducing gas passing through the final zone C is burnt in said bed 40.  The solids in bed 40 are passed into the reducing bed 45 together with cooler solid directly from the preheating zone, and there mix.  The proportions of ore entering the reducing zone from the preheating and heating zones are arranged to give a suitable temperature for reduction, and the partition may be so placed that the cross-sectional areas of beds 30 and 31 correspond to these proportions; the depths of these beds may then be maintained substantially equal.
