Patent GB-427990-A (GB)
Title: Plate straightening machine
IPC: B21D1/02
Filed: 1933-12-27
Abstract: 427,990. Straightening plates by rolling. UNGERER, F., 6, Arlingerstrasse, Pforzheim, Germany. Dec. 27, 1933, No. 36401. Addition to 410,654. [Class 83 (iv)] In straightening hot-plates between a series of thin rolls c, d flexed by adjusting support rollers as in the parent Specification, each roller of a pair of support rollers F are arranged one on each side of the vertical plane through the roll axis. These rollers F can thus be of larger diameter and the gap r between one roller and the next forward roller can be wide to allow torn off pieces of plate to drop through more easily. Also owing to the larger rollers the gap between the top and bottom journals is larger to allow easier removal for torn off pieces of plate. The overhang of the journals f<1> also allows torn off pieces to drop towards the free side of the rollers unhindered. Each pair of support rollers F can be adjusted toward the roll d to flex it by means of a handwheel p and worm drive m moving the bearing bracket up or down. The worm drive can be coupled or uncoupled to allow individual adjustment of each pair of rollers F. Cooling water flows through the bore i<1> and i<2> of the support I thus cooling the journals. Lubricant passes through bore i<3> in the journal bracket i to the rubbing surface f of the journal f leakage into a catching groove u being evaporated or burnt, plates v preventing the oil from being thrown out on to the sheet. The combustion residue of the oil may be blown out by compressed air. The cooling water flows, as indicated by arrows, Fig. 1, into the base a and up into the yoke h to keep the machine at an even temperature. Specification 326,033, [Class 83 (iv)], is referred to.

Abstract: 367,894. Electric motors. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Nov. 27, 1930, No. 35743. Convention date, Nov. 27, 1929. [Class 35.] Machines with vapour and like rectifiers in place of commutators.-In an electric motor with a polyphase winding in which the different feeding points are connected successively over valves or vapour arcs, the winding is resolved into two or more equal and magnetically intermeshed winding-sections. In the form shown, the junctions of the stator winding-sections W1, W2 are connected to the anodes 1 .. 12 of a valve V and in order that the separate anodes shall successively allow the current to pass, the grids are successively given a positive impulse by causing the contact apparatus K to rotate synchronously with the rotor. The two sections W1, W2 operate alternately each during a half period of the alternating voltage so that the sum action of the pulsating direct currents in the two sections is the same as if both halves of the current waves were to traverse only one of the two windings alone. The rotor winding F is fed by direct current or may be connected in series with the supply transformer secondary, or, as a further alternative, it may be short-circuited.

Title: Process of fabricating thin film magnetic circuit devices
IPC: H01F10/26
Filed: 1963-09-23
Abstract: A thin magnetic film for electronic computers is made by coating a catalytically active substrate with nickel having a grain size of less than 0.1 micron, and then depositing on the nickel coating, a magnetic material, e.g. perm-alloy, having uniaxial anisotropy.  The nickel is deposited chemically from a solution containing from 25-35 grams/litre nickel chloride, from 1.5-15 g./l. sodium hypophosphite, from 40-60 g./l. ammonium chloride, and from 75-125 g./l. sodium citrate, the pH of the solution being within the range of 7.6-9.2 and preferably 8.8, while the temperature is 60-80  DEG C. and preferably 71  DEG C.  The substrate may be a sheet of polyethylene terephthalate which is cleaned by alkali and acid washing, coated with a polyester adhesive, and then activated by immersion in a 20 g./l. aqueous stannous chloride solution containing 10 ml./l. of concentrated hydrochloric acid at a temperature of 25  DEG C. and a pH of 0.9, then after rinsing, immersion in an aqueous palladium chloride solution containing 5 ml./l. of concentrated hydrochloric acid at a temperature of 25  DEG C.  The substrate may also be a catalytically active material, e.g. aluminium, iron, nickel, cobalt, and palladium or non-catalytically active material, e.g. gold, silver, and copper.  Alternatively a non-conducting substrate, e.g. glass, ceramic, or plastic may be rendered catalytically active by chemical or vacuum deposition of copper, gold, or silver, followed by immersion deposition of palladium. In a further example the nickel is deposited on copper which has been deposited on silver on a glass slide, the layers being subsequently peeled from the slide.  The nickel surface is exposed as a cathode for 260 seconds to electrolytic action in a plating bath comprising 218 g./l. nickel sulphate, 6.76 g./l. ferric chloride, 40 g./l. boric acid, and 1.5 g./l. of saccharin, the pH being 2.47 and the temperature between 20 and 30  DEG C.  The current density is 5 milliamps/sq. centimetre. The deposition may take place in a magnetic field of 100 oersteds oriented parallel to the plane of the surface.
