Abstract: 1494029 Methanol gasification CHEM SYSTEMS Inc 19 March 1975 [29 March 1974] 11434/75 Heading C5E Methanol is converted to methane at 225-500 C. by passing methanol into a reaction zone containing a suspension of a methanation catalyst in an inert liquid, the liquid flowing upwards to fluidize the catalyst and expand its volume by at least 5% and being capable of dissolving 0À1 to 10 wt. per cent of water, and removing the gaseous stream, of CO content less than 1À7 vol. per cent. In the preferred process preheated methanol vapour is injected via a line 5 into the flow of the inert liquid in a line 6 before it flows into the catalyst containing reaction zone 7. Methane is extracted via line 8 and liquid free of catalyst and containing dissolved by-product H 2 O is extracted via line 11 cooled and pumped back into line 6. Alternatively the catalyst may circulate with the liquid. The methane containing CO may be converted to further methane by a wet methanation reactor upstream of reaction zone 7. Liquids are separated from the product gas at 15, any inert liquid present being recycled via 17, and CO 2  and H 2 O are then removed from the methane. Suitable inert liquids are mineral oils, desulphurized gas oils and C 9  to C 12  aromatic liquids such as those obtained from naphtha refining.

Abstract: 985,810. Inking-apparatus. SAMUEL M. LANGSTON CO. March 29, 1961, No. 11463/61. Heading B6C. An ink fountain for a printing-machine comprises a frame, a fountain roller journalled in the frame, a shaft extending from one end of the roller, a first transmission element secured to and supported by said shaft, a housing supported on and embracing said element, a bearing interposed between the housing and the element in which the element may rotate with respect to the housing, a motor mounted on the housing, a motor shaft, and a second transmission element on said shaft meshing with said first transmission element. The fountain roller shaft 51, Figs. 1a, 2 and 4, carries at one end a casing 52 carrying antifriction bearings receiving the hub of a worm wheel keyed to the shaft and driven by a worm on the shaft of a motor 53 mounted on the casing, which is loosely secured to a plate 56 on a frame member 27 by screws 59 passing through oversized openings 61 in the casing. The ductor roller 12, Figs. 4 and 7, is mounted at each end in an arm 65 of a lever 66, the hub 67 of which is supported on a pin 68 through a resilient sleeve 69. The pin 68 is clamped by a screw 83 and is rotatably adjustable to regulate the normal position of the ductor roller with respect to the fountain roller 11 and a transfer roller 13. The ductor roller is oscillated about the pin 68 by the piston-rod 74 of an hydraulic cylinder 75, movement of the rod being limited by nuts 77, 78 thereon engaging a stationary flange 69. Transfer rollers 13, 15 are driven from the power source of the printing-machine through gears 111, 106, 107, 104, Fig. 8, the gear 111 being slidable axially out of engagement with the gear 106 by means of a handlever. The rollers 13, 15 are axially reciprocated by means of a lever 98 on a shaft 99, the lever 98 being oscillated by an hydraulic piston-rod 102. The hub 117, Figs. 9 and 10, of the lever 98 has secured thereto a collar 118 having a fork 121 which reciprocates axially a screw 123 threaded into arms 125, 126 of sleeves 127, 128 rotatable on the hub, whereby the arms are oscillated and fingers 131, 132 thereon engage pins 133, 134 on a collar 135 to oscillate the rotary element of a valve 137. In operation, an electric motor 147, Fig. 6, drives two hydraulic pumps 145, 146, the pump 145 actuating an hydraulic motor 53 which drives the fountain roller 11. The pump 146 supplies liquid to a valve 159 and thence to the piston 162 to reciprocate the rollers 13, 15. Liquid also passes to the valve 137, which controls the valve 159, and as the valve 137 is controlled by the piston 162, the valves 137, 159 and piston 162 constitute an automatic and continuous system. Liquid also passes to a valve 144 and thence to the cylinders 75 to control the ductor roller oscillation, the valve 144 being controlled by a cam 143 rotated through a variable speed transmission unit 140 from a gear 109 on the shaft of the gear 107.

Title: Improvements in or relating to telecommunication systems with particular reference to power supply arrangements therefor
Inventor: KELLY RICHARD
IPC: H04B3/44
Filed: 1949-05-03
Abstract: 674,141. Unattended repeaters. STANDARD TELEPHONES & CABLES, Ltd. April 28, 1950 [May 3, 1949], No. 11771/49. Class 40 (iv). [Also in Group XXXV] In a telecommunication system comprising a transmission line including a number of repeater stations, power for the stations is fed over the transmission line from both ends and the power unit output at one end is regulator-controlled and can only be connected to the line by current from the distant end. In a regulated power unit, Figs. 3 and 4, operation of a switch SWI energizes a motor MDI, via a relay ML, and a clutch CLU to drive downward a slider on the input of a transformer VTI to its lowest position so that a lower limit switch LLS is operated. Provided there is no fault in the line, current from the distant end operates a delayed relay DR to shut off the motor and places a relay under the control of a low output relay LO. The contactor CTR extends alternating current to the main rectifier unit via transformer VTI and to the rectifiers for the interlocked relays SF and FFR, extends an earth to the tongue of a marginal relay JC, and releases the relay ML and clutch CLU, putting the former under the control of a high-output relay HO. The operation of relay FFR blocks relay SF and prepares for the eventual operation of a relay CO by a relay FF which is operated by the energization of LO releasing relay Y. The relay CO energizes the motor raise relay MR to increase the regulated output, connects the unit to line, disconnects the DR relay and prepares a relay X for operation on the release of relay LO. As the current builds up relay JC first breaks the contacts VLC and eventually LC, the latter causing relay LO to release, stops the motor drive and operates relay X which inserts a very low-output relay VLO for emergency operation. Relay JC now regulates the output current between prescribed limits as determined by the setting of the contacts HC and LC. The closure of contacts HC will cause the motor to lower the output through the actuation of relay HO and the closure of contacts LC will similarly raise the output. The unit includes the following alarms: unit disconnected, rectifier fail, mains fail and smoothing condenser fail, and is designed to shut down over the contacts of JC in the case of rapid faults or over-the-limit switches HLS or LLS in the case of a slowly developing fault. In Fig. 1 the power units are shown to be series-aiding around a loop comprising the " go " and " return " cables of a transmission system but alternatively the power units 4 ... 7, may be connected so that each pair of units supplies a single line, i.e. the - ve terminals of both units earthed at one end and both +ve terminals earthed at the other.
