Title: Stamp affixer
IPC: B65C11/04
Filed: 1963-04-02
Abstract: 1,034,414. Stamp applying machine. DATALINK CORPORATION. April 2, 1963 [April 13, 1962; Dec. 11, 1962], No. 13024/63. Heading B8F. A stamp applying machine comprises a housing 10, having a pivotally opening door 12, containing a receptacle 16 holding a roll of stamps, feeding means 26, a reciprocating cutting and pressing means for applying the stamp to an article and a removable water can 66 adapted to squirt water on to the article through perforations in the can before the stamp is applied, the said can containing a spanker pad biased against the perforations by resilient means and by a block of resilient, closed-cell foamed material. In the machine shown in Fig. 3, which uses a can assembly not in accordance with the invention, the stamp strip 20 emerges through an opening 18 in the container 16 bounded by the beading 22 and passes over a roll 24, to remove the curvature of the stamps, and to a feeding means 26 shown as a triangular-shaped rod with sides of a length substantially equal to the length of a stamp and having pins in the corners of the triangle to engage the stamp perforations. The body 26 may have other configurations having more than three sides. A spring-loaded shoe 32 surrounds part of the triangular block 26 and has a horizontal portion 36 acting to support the stamps. A cap 14 of the housing is reciprocable and has mounted to it an actuator frame 52 containing at the lower end a presser pad 54, a spring-loaded pivoted knife means 60 and a spring-loaded pivoted striker plate 96. The knife 60 is maintained by spring 62 in contact with plate 44 having an aperture 46 through which the stamp 136 protrudes and the lower edge 48 of which coacts with the knife 60 to sever the stamp. The spring 62 also serves to return the actuator frame 52 and the cap 14 to the inoperative condition. The removable can in Fig. 3 contains a leaf spring 86 having at one end a spanker pad 88 which in the inoperative position closes holes 94 in the can 66. As the cap 14 is depressed the striker plate 96 engages a push-rod 90 which depresses the leaf spring 86 to disengage the spanker pad 88 from the holes 94. As the cap is further depressed the push-rod 90 is released and the pad 88 springs back to eject water on to the article. Further depression of the cap 14 causes the stamp to be severed and applied to the article. When the cap is released the striker plate 96 is pivoted anticlockwise against the action of its spring as it engages the pushrod 90 until it is disengaged from the rod. The modified water can according to the claim is illustrated in Figs. 13 to 15 (not shown) and incorporates a resilient block of closed cell foamed material positioned between the leaf spring and the opposite side of the can to aid in biasing the leaf spring towards the holes and to counteract the increase in pressure that may be formed in the water as the push-rod 90 is depressed.

Title: Improvements in processes for the treatment of alloys containing iron and chromium
IPC: C21C7/00
Filed: 1934-05-01
Abstract: Part or all of the chromium in iron-chromium alloys is concentrated into a slag by treating the alloys with oxygen- and sulphur-containing media which slag off the chromium partly as chromium oxide and chromium sulphide, the slag thus produced having a relatively low melting point.  The sulphur containing medium may be a sulphide of metal which has the sulphur not more strongly combined chemically than it is in chromium sulphide such as the sulphides of iron, nickel copper or molybdenum.  The chromium may be recovered from the slag in any suitable manner. In one form of carrying out the process, a molten iron-chromium alloy is oxidized so that practically the whole of the chromium and part of the iron is oxidized.  The low melting point slag produced is reduced with a new melt containing chromium and a sulphur containing medium such as elemental sulphur, iron pyrites or a sulphide of the kind referred to above is then added.  In another form, the alloy is treated with an oxide-sulphide slag whereby part of the chromium is slagged off and then the alloy is finally oxidized by a slag only containing oxide or slag off practically the remainder of the chromium in the alloy.  This iron content of the refining clay may be reduced by the addition of reducing agents other than chromium.  The process may be carried out in ordinary basic metallurgical furnaces and different combinations of furnaces may be used for the two part proceess, e.g. the refining may be carried out in an open-hearth furnace and the reduction of the clay with the sulphides &c. in a mixer, open hearth or electric furnace.
