Title: Data processing circuitry
IPC: G06F11/16
Filed: 1976-04-26
Abstract: 1498353 Data processing SIEMENS AG 26 April 1976 [13 May 1975] 16757/76 Heading G4A Data processing circuitry processes phase encoded binary data, the two logic values being represented by square wave signals of the same frequency but opposite phase, and includes true OL and complementary KL channels, each channel cincluding a processing stage which, together with the corresponding stage in the other channel, is connected to a monitoring circuit U5 which checks that the outputs from the two stages are complementary. Each stage includes two read only memories FR10, FR20; FR1K, FR2K, one storing true data at true addresses and the other complementary data at complementary addresses and the arrangement is such that during the first (positive logic) half of the cycle of the square waves of the input signals AT1-ATn, AT1- #ATn, the true read only memories FR20, FR2K are addressed by the signal levels on the inputs via switches 2UG10-2UGnO to produce output signal levels, and during the second (negative logic) half of the input signals the complementary read only memories FR10, FR1K are addressed by the signal levels on the inputs via switches 2UG1K-2UGnK to produce output signal levels so that conventional static read only memories may be used with dynamic phase encoded input signals to produce dynamic phase encoded output signals. The logic relationship between the input and output data is not stated. In the halves of the cycles, in which they are not used to produce outputs the ROMs are connected by the switches to counters ARO, ARK which produce test addresses. Test devices U3, U4 test for complementary data at the outputs of the pairs of memories FR10, FR1K; FR20, FR2K, and test devices GU1, GU2 test for complementary data between the pairs of memories FR10, FR2K; FR20, FR2K, when addressed by the counters ARO, ARK, the devices GU1, GU2 including inverting delays VGO, VGK since the two memories in each pair are accessed in different halves of the cycle. All the switches SGO, 1UG10, 1UGO &c. are controlled by dynamic phase encoded signals representing either binary 1 or binary 0, the devices GU1, GU2 since they are used only once during each cycle, being used to compare their controlling signals during the half cycles when they are not in use.

Patent GB-352672-A (GB)
Title: An improved process for obtaining low-boiling oils from solid carbonaceous materials
IPC: C10G1/00
Filed: 1930-06-04
Abstract: Low-boiling hydrocarbons are obtained from coal, or other solid or semi-solid tarry or asphaltic material, by subjecting it in a fluent form to a preliminary treatment with hydrogen under pressure in excess of 20 atmospheres, e.g. 200 atmospheres or more, and at temperatures of from 600-950 DEG  F. to produce an oil mainly boiling above 400 DEG  F. which is subsequently cracked; the oil produced contains phenolic and other impurities which are removed before the cracking operation by washing with immiscible solvents such as aqueous alkaline solutions, glycol, glycerine, alcohol, acetic and inorganic acids, organic esters or liquid sulphur dioxide.  Coal is powdered in a mill 1, mixed with oil supplied by a pipe 2 and pumped into a chamber 4 supplied with hydrogen, or a gas rich in hydrogen, by a pipe 7, heating being effected by electric radiators 5 and agitation by stirrers 6.  To prevent accumulation of ash, part of the material is continuously withdrawn by a pipe 8 and passes through <PICT:0352672/III/1> heat exchangers 9, 10 to a separator 11 where ash is removed and the tarry material returned by a pipe 12 to the hydrogenating chamber.  Gas and distillate pass by a pipe 14 to a rectifier 15, light oil and gas passing by a pipe 19 through a condenser 16 to a separating-drum 17 whence the oil is drawn off and the gas passes through a purifying system 19<1>, a pump 20 and a pipe 21 to the pipe 7 after being preheated in the rectifier and heat exchanger 10; additional hydrogen may be added by a pipe 21a. Condensate from the rectifier passes by the pipe 18<1> through a cooler 22 to a gas separator 23 which is at a lower pressure than the chamber 4, any released gas being removed by a pipe 24 to the purifying system.  From the gas separator the oil passes by a pump 26 and a pipe 27 to a mixer 28 where it is thoroughly mixed with a solvent for removing the impurities referred to above, the mixture passing to a separating drum 30.  Solvent is withdrawn by a pipe 31 and the purified oil passes to an accumulator 33 and thence through a cracking coil 36 to a digestion drum 37 and a tower 38 where it is separated into at least three fractions. Light distillate passes to a condenser 40 and a gas separator 41; heavy distillate, condensed by a coil 42, passes by a pipe 43 to the accumulator 33.  Hydrogenation is effected at 600-950 DEG  F., preferably at 700 DEG  F., and the pressure may vary from 20-500 atmospheres.  Cracking temperatures may be between 750 DEG  and 1100 DEG  F. in either the liquid or vapour phase and the pressures are in excess of atmospheric.

Title: The production of liquid pig iron or steel
Inventor: BENGTSSON ERIK AXEL
IPC: C21C1/00
Filed: 1965-04-26
Abstract: Solid ferrous material, such as scrap and/or sponge iron is melted to produce pig iron in an horizontal or inclined rotary furnace using an oxygen-containing gas and sufficient solid carbonaceous fuel e.g. coal or coke to maintain a continuous cover of fuel over the bath by introducing the oxygen-containing gas above the cover, e.g. by blowing the gas both obliquely against and horizontally over the cover, so that the exhaust gas leaving the furnace contains by volume no more than 10% O2 and has a ratio by volume of CO2:(CO+CO2) of at least 2:3.  Slag formers such as limestone may also be added.  On tapping the pig iron formed, the fuel cover and preferably the slag with some pig iron may be left in the furnace for a subsequent melting operation, the slag being tapped off before the end thereof. The remaining fuel cover may be burnt with oxygencontaining gas after any melting operation to convert the pig iron to steel.  Liquid and/or gaseous fuels may also be used during the melting.  The solid ferrous material may also, include prereduced iron ore.  After slagging, ferromanganese and ferrosilicon may be added to the steel prior to tapping.

Title: Control means for series connected cylinder drive assemblies
IPC: B30B15/24
Filed: 1963-05-03
Abstract: 975,550. Hydraulic presses. PACIFIC INDUSTRIAL MANUFACTURING CO. May 3, 1963 [July 17, 1962], No. 17526/63. Heading B5F. In an hydraulic press comprising a ram 7 operated by two or more series-connected cylinder drive assemblies 9, 11, means are provided for limiting the maximum permissible force on each of the pistons 17, 25 of the assemblies 9, 11. The invention is described as applied to a press brake having dies (not shown) mounted on a bed 5 and the ram 7. A pump 31 supplies fluid through a reversing valve 41 and line 47 to the assembly 9. The lower side of the assembly 9 is connected by a line 49 to the assembly 11 which is itself connected to the valve 41 by a line 53. The underside of the piston 17 and the upper side of the piston 25 are equal in area. The means for limiting the maximum permissible loading comprise, for the piston 25 a relief valve 74, and, for the piston 17 a relief valve 87. The relief valve 87 comprises a valve 95 which opens when the upward fluid pressure on a piston 99 overcomes the downward pressure of a spring 107 and fluid supplied through a bore 131 under control of a pilot valve 121. Ram levelling means.-This comprises a cable 171 passing over sheaves 175, 177 and connected at one end to a fixed bracket 179 and at the other end to a valve 161. Tilting of the ram 7 will connect the cylinder assembly 11 either to the pump 31 through ports 155, 157 to increase the pressure on the piston 25, or to the supply tank 35 through ports 155, 159 to decrease this pressure. Adjustment is effected by a screw 199. Failure of cable 171 would allow a spring 167 to cause the valve 161 to operate an emergency switch 201. Controlling stroke of ram.-This is effected by means of an adjustable stop 241 adapted to engage an arm 239 and move a valve 231 downwardly against spring action. Hydraulic pressure supplementing the spring 107 against the valve 95 will thus be relieved to the tank 35, and valve 95 will be raised by pump pressure on piston 99. The pump will thus be connected through valve 87 to the tank 35 and the ram 7 brought to a halt within 0.001 inch. Specification 762,420 is referred to.

Abstract: 890,491. Converting; transformers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 2, 1958 [June 4, 1957], No. 17740/57. Class 38 (2). [Also in Group XXXVII] A supply system for D.C. traction motors M1, M2, includes a tapped transformer 1 and a pair of rectifier bridge systems, the tap changing system being such that it includes means to disconnect one rectifier system while its taps are being changed. As shown, a secondary winding 2 has main tappings 3, 4, 5, 6, which are connected through switches S1, S2, S3, S4 to a rectifier system of mercury arc or other rectifiers R1, R4, R5, R8, to a second rectifier system R2, R3, R6, R7. The two supply lines to the rectifier systems include transformer windings 7, 8 which have induced in them variable auxiliary voltages which have a maximum value of half that between tappings on the winding 8 and which may buck or boost the main voltage to give a fine variation. These auxiliary voltages are provided through windings 9 and 10 and switches S9-S20. Switches S21-S24 control the ignition electrodes of the rectifiers so that when a main tapping on the winding 3 is to be changed one rectifier system is rendered inoperative while the appropriate main switch in the bank S1-S8 is changed. In an alternative arrangement the appropriate rectifier system is cut-off by an arrangement which introduces excessive bucking voltage in the windings 7 or 8. In another alternative arrangement switches S21 and S24 are replaced by series switches in the supply lines. Specifications 880,378, 890,493 and 890,494 are referred to.
