Title: Improvements in or relating to the production of electrolytic tinplate
IPC: C25D5/50
Filed: 1963-09-16
Abstract: Sheet steel is, after cleaning, given an electrolytic flash coating of tin from an acid bath, the coating heated to reflow the tin and form a tin/iron alloy, again coated with tin electrolytically to the required thickness, and finally heated to reflow the tin coating. The flash coating gives a deposit of at least 0.05 lbs. tin per standard box of 31,360 sq. inches and the first heat treatment is effected preferably at 700  DEG F.  The second coating brings the total tin to 0.5 lb. per box, and heating is effected at 600-700  DEG F.  The acid tin plating bath preferably contains tin chloride. Graphs are given relating alloy-tin couple (corrosion) test with the temperature used in the first heat treatment which affects crystal structure and the tin-iron alloy formed on the steel sheet. Micro-photographs are illustrated.

Title: Diffusion of impurities into semiconductor substrates

Filed: 1974-08-22
Abstract: 1464734 Diffusion in semi-conductors INTERNATIONAL BUSINESS MACHINES CORP 22 Aug 1974 [17 Sept 1973] 36855/74 Heading H1K A semi-conductor diffusion process involves forming a doped insulating layer 3 on a semiconductor substrate 1, forming a second insulating layer 4 on the layer 3, opening windows 5 through the layers 3 and 4 and then heating to diffuse the dopant from the layer 3 into the substrate 1, firstly in the presence of hydrogen chloride and oxygen and subsequently in an inert atmosphere in the absence of hydrogen chloride and oxygen. During the initial stages of the heating process the hydrogen chloride serves as a getter for deleterious contaminants in the insulation while the oxygen oxidizes the exposed semi-conductor material in the windows 5 and prevents outdiffusion of the diffusing dopant. Optionally a thin insulating layer 2 underlies the doped insulation 3, in which case the dopant diffuses through the layer 2 into the substrate 1. All three layers 2, 3, 4 are preferably of oxide, at least the upper two layers 3, 4 being formed by chemical vapour deposition.

A rotary proofing press for a wrap-around plate comprises a gripper cylinder 14 for receiving a sheet to be printed, a rotary core or axle for receiving one of a number of interchangeable shells of different diameters, to constitute the plate cylinder 20 which receives the plate, a slidable self-contained inking system 40 for the plate cylinder, means driving the two cylinders in synchronism and means for adjusting the spacing between the axes of the two cylinders to accommodate changes in diameter of the plate cylinder. The drive to each cylinder may be uncoupled through a clutch independently of the other. Registering means comprising a plunger engageable in a correspondingly shaped recess formed in a rotary part in the associated cylinder are provided for accurately registering each cylinder in a predetermined angular position, for the start of each proof printing cycle. Each plunger is automatically controlled by a cam-operated mechanism responsive to the angular rotation of the respective cylinder, to cause the plunger to engage, or to be energized to engage, at a preselected point in the printing cycle. Means are also provided for (1) moving the two cylinders towards one another at the start of the cycle, and (2) automatically separating the cylinders after a selected angular rotation of the gripper cylinder. The automatic separating means is adjustable so as to accommodate for different circumferential lengths of the wraparound plate and avoid inking of the gripper cylinder. The printing cycle involves two complate revolutions of the gripper cylinder and means are provided for automatically actuating gripper and stripper mechanisms once in each two revolutions, at preselected points in the cycle, see Fig. 3 (not shown). The rotary core 21, Fig. 2, is formed to receive a shell having a radial opening or slot extending lengthwise and includes means for securing and accurately locating the shell 25 on the core.

A four sided carton has an opening between an opposed pair of side walls 3, 4 each side having an inwardly foldable extension 5, 6, the two extensions having a total width slightly greater than the unstrained distance between the said pair of side walls, and at least one of these extensions has an end flap 8 which is pressed into contact with the extension 7 and on applying force to the extensions 5, 6 the opening takes up the position as shown in Fig. 2. Alternatively the closure may be formed between the top and a sidewall, the extensions then meeting at the carton edge. The other two side walls have webs integral with the extensions 5, 6, said webs lying in gusset fashion flat on the inside of the carton when the carton is closed. The top of the carton may be formed with further extensions between the side walls 3, 4 and the extensions 5, 6 in which case the whole of the top of the carton is not below the side walls. In another embodiment one of the end flaps 13 is extended so that it may be partially or wholly stuck down on to the outer surface of the other end flap or stuck back on itself through spaces 7a cut in the other end flap 7 as shown in Fig. 2. All or part of one of the end flaps may be turned inwards to separate articles in the carton. The two end flaps 7, 8 may be plasticized by heated rollers which could also serve as transporting bands, or be held together by clips, glued paper or pressure sensitive tape. The opening of the carton may be facilitated by providing the end flaps with " U " or other shaped cut-outs displaced one from the other to give easy separation of the two end flaps. The carton may be lined with coated paper, impregnated paper, plastic film or aluminium foil in which cases the lining may be sealed between the end flaps of the outer carton.
