Chlorinated paraffins, e.g. C 15 -C 14  monochloro straight-chain paraffins, are obtained by a non-catalytic, liquid-phase process which comprises providing a chlorine feed mixture containing an inert gas and gaseous chlorine in a volume ratio between 0À5 to 1 and 10 to 1 and a paraffin feed mixture containing a chloroparaffin and the paraffin to be chlorinated in a molar ratio between 0À5 to 100 and 8 to 100, introducing the two mixtures to one end of a tubular reactor while maintaining therein a temperature between 80‹ and 150‹ C. and a pressure which prevents boiling of the paraffin in the reactor, and withdrawing from the other end of the reactor a liquid chloroparaffin product and a gaseous product containing hydrogen chloride. A portion of the chloroparaffin product may be recycled to the reactor. Specified inert gases are nitrogen and hydrogen chloride.

Title: Thermal dissipating metal core printed circuit board
IPC: H05K3/38
Filed: 1969-10-30
Abstract: 1276527 Printed circuits INTERNATIONAL ELECTRONIC RESEARCH CORP 30 Oct 1969 [1 Nov 1968 19 Sept 1969 13 Oct 1969] 53327/69 Heading H1R [Also in Division C7] A metal core printed circuit board has a circuit pattern on one or both sides, 'and possibly passing through holes in the core, formed on a layer 15 of synthetic plastics resin such as polyurethane coating the metal core, the layer 15 having keying-depressions 16 produced by mechanical and chemical etching to support the circuit pattern. The circuit pattern is made up of metal layers, the base layer of nickel 25 being keyed to the resin by means of the depressions and seeds of a pure metal, e.g. palladium (20, Fig. 5), deposited in the depressions. The other layers comprising the circuit pattern are a further layer of nickel 27, two layers of copper, 28, 29, the former being thinner than the latter, and possibly an overplating 35 of tin, solder or nickel. In an alternative embodiment (Fig. 16, not shown), the base layer of nickel (25<SP>1</SP>, Fig. 16) has layers of copper (26<SP>1</SP>), nickel (27<SP>1</SP>), copper (28<SP>1</SP>), copper (29<SP>1</SP>), and an overplating of tin-lead, gold or rhodium. In a further embodiment only the two layers of nickel 25, 27, and the copper layer 28 with an overplating metal form the circuit pattern. The metal sheet 10 is preferably aluminium but may be copper, a copper alloy, titanium, steel, magnesium or lithium-magnesium alloy, which is etched, anodized, treated with a primer, and coated with from three to ten coats of synthetic resin, heat cured, and sandblasted to produce cavities (17<SP>1</SP>, 18<SP>1</SP>, Fig. 6) for the seed metal (20, Fig. 5). The outer resin layer may contain nickel oxide or other metallic salt which is reduced to the metal to enhance adhesion of layer 25. Palladium metal is deposited from palladium chloride into the cavities (17<SP>1</SP>, 18<SP>1</SP>, Fig. 6), and electroless nickel layer 27 is deposited from given nickel salts on to the resin layer 15, followed by electrodeposition of the other metal layers. To form the circuit pattern the metallic layers are etched away, except where a wet or dry resist material protects them, or alternatively a resist material which may be applied using photographic techniques is applied to regions away from the circuit pattern which is thickened by electrodeposition of copper which receives an overplating metal of, for example, tin-lead, gold or rhodium. The resist material is then removed and the overplating itself protects the circuit pattern from the etchant which removes the metal layers elsewhere. In a modified process, nickel is grown on the palladium seeds from a nickel salt with boron reduction (Figs. 14, 15), followed by an electroless nickel deposit as before. Examples of etchants and other chemicals used are given, as well as examples of resist materials which can be used, and appropriate thicknesses of the various metal layers are given.

Abstract: 1404703 Input/output control INTERNATIONAL BUSINESS MACHINES CORP 26 Nov 1973 [2 Jan 1973] 54766/73 Heading G4A  Input/output channels 22, for executing I/O programs of channel command words (CCW) assembled by a central processing unit 10, are arranged in groups 12, 14, and unless an I/O instruction specifies a particular channel 22, channel group hardware assigns a non-busy channel 22 from the group to control the requested I/O operation. If an I/O device disconnects during execution of a series of chained CCW's the I/O operation may be resumed subsequently on any one of the channels 22 in the same group. It is also possible, e.g. for diagnostic testing, for a START I/O command to specify a particular channel 22, and in this case the selected channel controls the entire I/O operation. If a HALT DEVICE instruction occurs, channel selection logic determines if one of the channels is assigned to the device and if so routes the halt instruction through that channel. In operation, a unit (channel group) address from a start I/O instruction is translated by table look-up into a unit control word (UCW) address, the UCW is fetched from shared storage 18, 20 and subsequently a channel address word (CAW) is fetched from a predetermined storage location and is entered in the selected channel where it is used for indirect addressing of the first CCW. Since each set of UCW's 18, 20 is common to a group of channels 22 an interlock is provided which prevents any channel accessing a UCW until it has control of the corresponding channel/device interface.
