A method in a colour printing or like process, for effecting the registration of one or more sets of colour separation or like components with respect to one or more backing sheets, comprises intially registering the individual components of each set with each other and then registering the components of each set with respect to said backing sheet or sheets, by drilling at least two spaced registration holes through the or each set of components and the backing sheet or sheets, each hole being drilled through the components and sheet or sheets at the same time, and positioning the set or sets and the backing sheet or sheets in register one with the other by locating said register holes over register pins. In the described embodiment the layout sheet 1, Fig. 1, four separate carrier sheets of transparent film and a backing sheet, which may be opaque or transparent, are punched with holes 2. The backing sheet, four transparent carriers and the layout sheet 1 are mounted on a table, pins protruding from the table through the holes 2. As shown in Fig. 4 a first set of records A, B, C, D, e.g. printing plates, having register holes 14 are placed upon pins 5 and 6 and over these records is laid a metal bush plate 9 carrying drilling holes 10, 11. The aligned assembly is then moved to its appropriate position on the sheet 1, say in the area E, and is held over four previously located transparent sheets 3, the layout sheet 1 and the backing sheet 4 and drilled by the machine illustrated in Fig. 7 (not shown), through the bush plate guide holes 10, 11. The whole sequence is then repeated for each set of records indicated at F, G and H. Finally each set of records are broken into their component parts, all the A's being stuck by adhesive tape to layout sheet positions E, F, G and H on a transparent sheet 3 through the use of temporary pins through the drilled holes 10 and 11. All the B's C's and D's are similarly attached to associated sheets 3.

Patent GB-1012338-A (GB)
Title: Process for purifying sulfolane and homologues of the same
Filed: 1962-12-27
Abstract: Sulpholane or its homologues are purified by heat-treating the sulpholane for at least 5 hours at a temperature of at least 140 DEG C. and then subjecting it to a distillation treatment to distil off any impurities.  An inert stripping gas is preferably passed through the sulpholane during the distillation treatment.  The distillation is preferably followed by a second distillation in which the sulpholane is obtained as an overhead stream.  The sulpholane may be produced by a two-step process in which sulphur dioxide and butadiene are converted to sulpholene which is subsequently hydrogenated to sulpholane.  Examples are given. Specifications 951,501, 967,476, 969,544 and 1,012,337 are referred to.

The location of interface 104 between a liquid and the air or between dissimilar liquids, flowing from a vessel 101 to solenoid valve 106 is monitored by an A.C. bridge comprising a pair of capacitors situated at different levels in the liquid(s), the out-of-balance voltage or current created when the interface passes the intermediate level switching a control circuit 108 so that valve 106 remains open but closes as soon as the bridge is rebalanced. In Fig. 4 one capacitor is formed by the adjacent ends of electrodes 128, (126) and the other by electrodes 128, 127. Electrodes (126), 127 extend parallel to a point half way along the end of electrode 128, then (126) is bent up at 126' and 127 is bent down at 127'. The electrodes extend through a glass-metal seal 129 and are themselves coated with glass. Member 107 encloses the bridge and the first amplifier of the detection and control circuit (Fig. 6, not shown). The apparatus also includes a stirrer 121. Figs. 1 to 3 (not shown) illustrate a simpler version wherein the capacitors are formed by two axially spaced rings encircling a glass tube and a glass-coated electrode extending along the tube axis. The invention is applicable to separation by settling of organic and aqueous liquids following contacting thereof in chemical analysis, such as urine and ether.

[Also in Division F2] In a device for assembling a universal joint formed by two forked shafts 1 connected by a crosspiece 5, the pins 4 of which are received in bores 3 in the fork arms 2 by radial and axial load bearings 6, the fork arm holding clamp 14 together with the fork arm 2 may yield elastically by a predetermined amount during insertion of the bearing 6 into the bore 3 so that after pressing and disengagement of the clamp 14, the fork arm 2 springs back again. The bearing 6 is pushed into the bore 3 by a piston 11 causing the clamp 14, together with the fork arm 2, to move forward against the action of a spring 21 by a distance limited by the abutment of a nut 20 with a collar 18. When it is desired to produce no clearance between the end of the bearing 6 and the pin 4, the nut 20 is moved to abut the collar 18 thereby preventing movement of the clamp 14 during the pressing-in operation.

Abstract: 1,177,579. Developing electrostatic images. INTERNATIONAL BUSINESS MACHINES CORP. Nov. 1, 1967 [Nov. 7, 1966], No.49621/67. Heading G2H. A latent electrostatic image formed on a di-electric web by electro-graphic printing or on a web 10 having a zinc oxide coating 10a by charging and exposure in known manner is developed by moving the web adjacent an inking roller 28 and applying a potential difference between the surface of the roller 28 and the uncharged areas on the web so that ink is attracted in an unsupported column from the surface to these areas. The roller 28 dips in ink supply 30. A doctor blade 33 spaced from the roller 28 provides a required thickness of ink on the roller. The roller 28 is connected to a terminal 34 to provide an electric field in the gap 24 which causes ink to rise bodily from the roller surface towards the image surface on the web 10 and deposit on the uncharged image areas. The ink used for developing the latent image may comprise a dye in water. Examples of the dye are Acid green, Acid blue, basic blue, and basic violet. A 1% solution of these dyes provides a self-fixing developer without using resin binders. Alternatively, a colloidal suspension of carbon black in dimineralized water with the addition of polyvinyl alcohol to remedy smearing may be used. Toluene and nitrile silicone may also be used as carrier liquids.
