Patent GB-926334-A (GB)
Title: Process and apparatus for the production of metals or ferroalloys
IPC: C21B13/12
Filed: 1959-07-29
Abstract: In a process for the reduction of metals and alloys from oxidic materials, the latter and solid reducing agent are continuously charged to a refractory-lined arc furnace in such proportions that the slag formed always contains a proportion of the reducible oxide, whereby a layer of carbon-free metal or alloy is caused to form at the bottom of the furnace.  The reduction of complex ores may be so controlled that only the desired metals are reduced, e.g. iron and nickel may be reduced while chromium is retained in the slag.  The furnace is so constructed that certain minimum depths of metal and of slag are always retained therein; tapping is carried out intermittently from two vertically spaced tapping holes.  The electrodes are adjustable to be either slightly immersed or slightly above the level of the slag, so that heat is generated in the upper part of the slag layer, the depth of the latter being such that the metal is maintained at a temperature slightly above its melting point by conducted heat.  Pre-reduction of the charge may be carried out in a rotary furnace or fluidized bed, and may be carried on to such an extent that no further reducing agent need be added at the electric furnace smelting stage.  The direct production of low carbon steel is exemplified.

Title: A Method and Apparatus for Clamping a Sheet of Material
Inventor: STRAUBE PETER
IPC: B41F21/10
Filed: 1968-05-30
Abstract: 1,192,867. Gripper apparatus. DRUCKMASCHINENWERKE PLANETA VEB. 30 May, 1968, No. 26046/68. Heading B6C. In a sheet gripper mechanism mounted on an impression cylinder the gripper tongue 7 is connected to a gripper cradle 2, freely rotatable about a gripper shaft 1, through two parallel leaf springs 5 so that the movement of the tongue to its clamping position is in two parts during the first of which the tongue moves in a circular path about the axis 19 of the shaft 1 and during the second part of which the tongue moves in a direction perpendicular to the sheet bearing surface 18 of the cylinder. The cradle 2, and therefore the tongue 7, is biased to clamping position through a spring 8, and during the first part of the tongue movement the shaft 1, which is moved in a clockwise direction throughout the entire movement, is followed by the cradle until a lug 9, which is attached to the cradle, abuts a stop screw 10 on the cylinder. During the second part of the movement, during which the cradle remains stationary, an abutment 11b, fixed to the shaft, moves away from a spring arrangement 12, 13, 15, to allow the leaf springs 5 to move the tongue 7 towards the surface 18 and into clamping engagement therewith.

Means for closing the opening in the front end of the barrel (1), Fig. 1, of a fountain-pen when the nib (10) is retracted comprises a generally cylindrical cover plate holder (4), Figs. 1 and 3, secured in the barrel and having an inclined face 4c and a pair of recesses (4d) for receiving pivot pins (5a) of a cover plate (5) urged by a leaf spring (7) against the face (4c). On projection of the nib, the latter forces the cover plate into open position against the force of the spring. A collar (6) secured on the holder (4) has a pair of end plates (6a) which pass in front of and in contact with the pins (5a) to hold the latter in the recesses (4d). In the barrel is also secured a cylinder (2) having a projection (2a) engaging a spring (11) for urging the nib and reservoir (9) to retracted position. An inner cylinder (3) has a rear portion (3b) in tight engagement with the barrel. In another form, Fig. 6, the cover plate holder (14) with inclined face (14c) is provided with an extension (14g) having an inclined end face (14h) leading to a pair of cut-outs (14e) extending the recesses (14d). The collar (6) is omitted, and the pivot pins (5a) are forced into the recesses through the cut-outs, the holder (14) being somewhat elastic for this purpose.

Convention date, Sept. 4, 1929. [Class 100 (iv).] Type-wheel machines for coding and decoding.- A coding and decoding device consists of a series of discs bearing letters or signs on the periphery and arranged in pairs on a shaft. The pairs of discs 6, 7 are separated by partitions 1 connected together by rods 3. The characters on the discs 6 are formed in intaglio or are inscribed flat on the surfaces, but those on the discs 7 are in relief so as to be capable of printing. The discs 6 are formed with a series of apertures corresponding in number to the number of characters, and arranged near the edge of each disc, and the discs 7 are provided with two diametrically opposed apertures housing balls 8 adapted to be projected by springs to engage with the apertures in the discs 6 to maintain the discs in adjusted position. The discs 7 are provided with two other apertures on the opposite face, these apertures also containing spring-pressed balls adapted to engage apertures in partitions 1, the coupling between the partitions 1 and discs 7 being weaker than that between the discs 6, 7. The relative positions of the discs 6, 7 in each pair are arranged according to a prearranged key, the message to be coded or decoded is set on the discs 6 against indicating marks 16 on the partitions 1, and the cipher or clear text is read on the discs 7. The outer partitions pivotally support segments 10 connected together by rods 12 and strips 11, the strips 11 being soldered to the segments 10 to form a frame in which is mounted a strip of felt soaked in ink and held in place by a cover 13. A paper strip 14 is passed over the rods 12 and under the felt, and pressure on the cover 13 causes the relief characters on the discs 7 to make an impression on the paper strip. The inked felt may be replaced by carbon paper.

The top wall 20 of the retort carries a journal 26 through which passes the hollow spindle 23 on which is mounted the shoot 21, making a dust-proof fitting with the underside of the wall 20. The shoot 21 is inclined so that its discharge end is non-axial with the retort, and attached to it is an extension 28 which trails on the surface of the fuel bed 29. 'The spindle 30 about which the extension 28 swings is fitted with a cranked portion 32 which is connected to the lower end of a vertical rod 33 which passes through the hollow spindle 23. Thus variations in the level of the fuel bed are indicated by an index finger 34 on the rod 33 and a fixed scale 35.

A ring 32 of non-magnetic material is secured to plate 17 and is slotted to receive the pole 12 of the housing, the magnetic reluctance of the gap 25 between the pole and the disc being less than that of the gap 18, the reluctance of which is defined by the fact that the relative positions of the poles are fixed. The disc 24 is slidable along a roller 27 of ceramic material around which the thread passes while being tensioned, the disc and plate being shaped as at 30, 31 to minimize wear. The tension may be adjusted by varying the current through the electromagnet and by applying weights to the disc 33 which is shaped for the purpose.
