Title: Improvements in or relating to addressing and like machines
IPC: B41L11/00
Filed: 1926-02-25
Abstract: 267,696. Pilz, W., and Pilz, J. Feb. 25, 1926. Addressing and like machines; copying documents. -An addressing or like machine employs strips of paper on which the addresses are reproduced in copying or hectographic ink in reversed manner, printing being effected by applying pressure and heat or pressure and moisture. To make an address strip, the addresses are written or typed on a strip of paper under which is placed a sheet of carbon paper with its inked side against the back of the strip, or strips may be made on a duplicating-machine. In one form, the pressure-applying arrangement comprises a roller 1 and a segment 2. The address strip is laid on a table 6 with its end over the roller 1, an envelope 12 to be addressed is placed between guides 13, 13<1> so that it rests on stop fingers 8, and the segment 2 is rotated by turning a handle 5, the stops 8 being then withdrawn by means of a cam 10 acting on an arm 11. After the address is printed, the envelope is released and falls out of the machine. The roller 1 may be heated, or the envelope may be moistened with water, alcohol, acetone, or a mixture of these in which soap is dissolved. In one modification of the arrangement for applying pressure, the roller 1 is a complete cylinder, which is separated from the roller 1 during part of each revolution by means of a cam; in a third, the roller 2 is replaced by a curved plate alternately pressed against and removed from the roller 1; and in a fourth, the roller 1, is replaced by a fixed block, and the roller 2 by a platen, which is actuated by means of toggles.

Title: Process for manufacturing nitrated cellulose from wood-pulp and apparatus therefor
IPC: D01F2/26
Filed: 1925-02-27
Abstract: 230,092. Planchon, V. Feb. 29, 1924, [Convention date]. Cellulose nitrates.-For the manufacture of nitrocellulose, wood pulp in the form of thick sheets of low porosity is employed and the nitrating-acids are maintained at a temperature of 5-15‹ C.; operating in this manner, the time required for nitration is several hours, depending on the temperature selected, and the process is easily controlled. The sheets are preferably suspended vertically a short distance apart, for example, in a rack as shown in Fig. 1, or suspended on rods passed through perforations in the sheets as shown in Fig. 2. The nitration-apparatus conveniently consists of a water-jacketed vessel A. B provided with a cover and with supports D for the sheets. The vessel is filled with nitrating-acids from a tank F, to the level of the funnel G; after nitration, the waste acids are run off into a tank N, and after allowing the sheets to drain, washing water is run in, overflowing through the pipe R and finally being drained off through the pipe S. The nitrated sheets are removed and subjected to the usual processes of stabilizing &c., and finally dried; during all these processes the sheets are maintained in their supports, and the dried sheets may be cut up like ordinary cardboard. Instead of drying, the moist sheets may be arranged in a pile and subjected to pressure, or they may be reduced by rotary crushers to a light pulp.

Abstract: 1,125,044. Blow-moulding; deflashing. N. HAGEN. 9 Feb., 1966 [9 Feb., 1965], No. 5699/66. Heading B5A. Hollow bodies are blow-moulded from thermoplastic material in a mould in two or more parts which has cutting edges, one or more blows being struck on the closed mould to assist in pinching the product to form flash and preferably welding seams together. The blows are preferably struck in the closing direction and may be before, and/or after, the material has solidified. Preferably, only those parts of the extrudate which are to be welded together come initially into contact due to mould closure, excess being pinched off essentially due to the blow(s) struck. The blows may be struck simultaneously or not and from two or more sides of the mould (if two, they are preferably opposite), a mid-portion of the mould walls, in the squeezing or pinching regions or on the mould supports. Each mould section may have a striker device associated with it; the striker device is preferably metallic and moved by a spring towards the mould, tensioned by retraction of the striker on mould opening and held in the retracted position for a time delay before release. Alternatively, the striker may be moved by compressed air or magnetic forces, and as a result of the application of high frequency electric impulses, or by means of an ultrasonic hammer. The mould may have a projection against which the striker strikes and which may have a thin covering of rubber &c.

Title: Process for dephosphorizing molten pig iron
Inventor: KOOTZ THEODOR
IPC: C21C1/02
Filed: 1965-02-10
Abstract: Molten pig iron, particularly one containing above 1.5% P, is dephosphorized in a refining vessel e.g. converter or rotary furnace by top blowing with oxygen, the weight ratio of basic materials (CaO and MgO and any alkali metal oxide) to acidic materials (SiO2, TiO2, Al2O3 and P2O5) in the slag being kept within the limits 0.8 to 1.5 by controlling the addition of slag formers, the temperature in the bath being kept below 1500 DEG C. by adding cooling agents such as scrap iron, and the bath being mechanically agitated e.g. by rotating the vessel.  The slag formers may comprise basic materials, e.g. burnt lime added continuously as powder or at intervals as lumps and additionally, after removal as slag of most of acid formers in the iron, acidic materials.  After slag removal, lime may be added again, the end slag being left for use in a subsequent heat.  The sulphur content of the pig iron is also reduced e.g. from 0.04% to 0.015-0.02%.

Abstract: 816,352. Hardening metals by induction heating. MORRIS MOTORS Ltd. Jan. 27, 1958 [Feb. 21, 1957], No. 5851/57. Class 72 [Also in Group XI] A high frequency induction hardening machine for treating a set of equi-spaced identical, workpieces one after another, comprises mechanism for conveying the set of workpieces step-by-step in an endless path, a single-loop high-frequency inductor and an associated quenching device mounted adjacent that path, mechanism to introduce each workpiece in turn into the inductor and withdraw it after a predetermined interval, and provision for stopping the machine and switching off the power supply to the inductor automatically after the last workpiece of the set has been treated. As shown, a gear ring 1 is located and free to rotate on a circular supporting plate 2 which has a central bearing 3 carried by a platform 4 tiltable about a fulcrum 5 on a bracket 6 fixed to a base plate 7, and to rise and fall intermittently by an electrically driven cam 9 and its follower 10 which is attached to the platform through arm 11. At each upward movement of the platform 4 the supporting plate 2 is rotated by means of slot like cam 13 and its follower 12 to cause ring 1 to advance 1 tooth. When the platform descends plate 2 returns to its original position but the ring is prevented from rotating with it by a pawl 14. A liquid cooled single loop inductor 15 fitted with current feed plates 16 is mounted with an associated oil quench jet 17 so that as the ring is raised, one tooth is caused to enter the field of the inductor before being withdrawn and rapidly quenched by the oil jet at 17. A loose radial arm 18 which can be hinged upwardly at 19 is attached to the ring gear 1 and has a projection 21 which actuates a micro-switch 22 to turn off the power supply to the machine when the last tooth has been hardened. Used oil returns to tank 27 where it is cooled by water cooler 28. In a modification, Fig. 4 (not shown), tappet screws may be arranged to protrude through recesses spaced equidistantly around a toothed annulus. Specification 613,323 [Group XI] is referred to.
