Patent GB-597598-A (GB)
Title: Gas purification process
IPC: C10K1/12
Filed: 1945-08-23
Abstract: <PICT:0597598/III/1> In a process for the recovery of hydrogen sulphide from coke oven gas by scrubbing the gas with an aqueous alkaline liquor which absorbs the hydrogen sulphide the fouled scrubbing liquor is regenerated by heating it at sub-atmospheric pressure with steam formed by the indirect contact of regenerated scrubbing liquor with hot coke oven gas after the latter flows from the collecting mains of a coke oven battery.  As shown, coke-oven gas is scrubbed in tower 4, passing in through pipe 2 and out through pipe 6, the scrubbing liquid, for example a sodium carbonate solution, being sprayed through nozzles 74.  The fouled liquor from the bottom of the column passes to tank 10 into which fresh solution made up in tank 14 is also pumped.  The mixed liquids are pumped through line 24 and sprayed through nozzles 28 in the top of regeneration tower 26, up which steam is passing.  Uncondensed steam and hydrogen sulphide leave the top of tower 26 through pipe 30, and pass through condensers 32 and 36, the hydrogen sulphide being extracted by pump 40 which maintains a subatmospheric pressure in the regeneration system, and the condensed steam passing to tank 80 whence it is pumped into the base of tower 4 for recirculation. A part of the regenerated absorbant from the bottom of tower 26 is pumped by pump 62 to a cooler 66 and thence to nozzle 74.  The remainder of the solution is pumped by pump 46 into indirect heating contact with gas direct from the coke-oven battery, the contact taking place through coils 50 in heat exchanger 52 which acts as a primary cooler for the coke-oven gas.  The temperature of the solution may be raised 10 DEG C and when it passes through pipe 59 into the base of tower 26, is partially vaporised supplying steam to strip the fouled absorbant passing down the tower from nozzles 28.  A reboiler 27 may also supply heat at the base of the tower.  Both towers 26 and 4 contain packing.

Title: Control system
IPC: H04N5/782
Filed: 1962-06-05
Abstract: 1,013,252. Recording television signals. NIHON VICTOR KABUSHIKI KAISHA. June 5, 1962 [June 21, 1961], No. 21698/62. Heading G5R. [Also in Division G3] In a helical scan magnetic recording system for television signals, the position of the frame sync. pulse is stabilized near the start of each scan by controlling the speed of the rotating disc 8 carrying the recording heads 9, 9<SP>1</SP>. Playback heads 10, 10<SP>1</SP> mounted on the disc between the recording heads immediately re-scan the tape to provide control signals. Control system.-A pulse is derived from the playback head as the recorded signal commences at the start of the scan, and a second pulse from the recorded vertical sync. pulse. The first pulse passes through a delay circuit 24, and is compared with the second (sync.) pulse in a phase comparator 25 to control an oscillator 26 supplying a motor 11 driving the disc 8. Thus the delay circuit determines the position in which the sync. pulse is recorded relative to the start of the scan. In an alternative arrangement, Fig. 5 (not shown), after initial positioning of the recorded sync. pulse, as above, when the output of the comparator falls to zero, a relay circuit operates to connect the drive oscillator so that it is controlled by comparing a speed signal from a tachometer generator, driven by the motor, with incoming sync. pulses to be recorded.

A treatment tank 3, in which packages 6 are supported in tiers by skeleton supports 10 and annular rubber spacers 32, is supported in a readily removable manner on a fixed base 2.  Thus, a tank loaded with packages can be removed from one base to another for various treatments.  The tank has a bottom 32 formed with a series of ports 43 communicating with the interior 41 of the package tiers and another series of ports 45 communicating with the tank space 42 around the tiers.  It has also a removable cover 31, an overflow 13, and rubber base members 31 on which the package tiers are pressed by rubber caps 33 and spiders 37.  All parts of the apparatus are formed of non-corrosive material or are coated with rubber.  The supports 10, Fig. 13, consist of split rings 111 connected by rubber-covered rods 112.  The fixed base 2 comprises an upper casing 61 and a lower casing 461.  The upper casing 61 is divided, by transverse partitions and two series of inclined plates 47, 48, into two series of alternating transverse chambers.  The lower casing is divided by a partition 104 into two longitudinal chambers 53, 62.  The transverse chambers defined by the plates 47 communicate at their upper ends with the ports 43 and at their lower ends with the chamber 53, while those defined by the plates 48 communicate with the ports 45 and chamber 62. In operation, liquid is passed alternately from the chamber 53, outwardly through the package 6, and back to the chamber 62, and from the chamber 62, inwardly through the packages 6, and back to the chamber 53, such reversing liquid flow causing a pulsation and a periodic deformation of the packages on the supports 10.  The chambers 53 and 62 are respectively connected by pipes 58, 641 and 63, 631, Fig. 1, to a four-way valve 68 which also is connected by a pipe 69 to a pump 8 and by a pipe 74 and filter 72 to a pipe 66.

Title: Improvements in or relating to indicating and control instruments
Inventor: ALEXANDER RONALD MCEWAN
IPC: G01D13/24
Filed: 1965-05-26
Abstract: 1,097,688. Automatic control. HONEYWELL CONTROLS Ltd. May 19, 1966 [May 26, 1965], No.22305/65. Heading G3R. The value of a variable is continuously indicated by an instrument pointer relative to a set point for a control system selected by an adjustable reference pointer, the relative position of the pointers being detected by a pair of sensors which control a relay and respectively change their state over differing but overlapping ranges of movement of the instrument pointer, the latter being temporarily biased to a particular side of the reference pointer when starting up. As applied to an automatic control system, the magnitude of a variable is indicated relative to a scale 1, Fig. 1, by a pointer 2 which may be operated by a self-balancing bridge circuit responding to the variable. The set point of the system is determined by manually or remotely positioning an index 5. The latter carries a lamp 9 and photocells 7, 8, while pointer 2 carries vanes 10, 11. When the magnitude of the variable is below the set point, as shown, both photo-cells are illuminated, and a transistor circuit, Fig. 2 (not shown), associated with them energizes a relay to operate means (e.g. a fluid valve) to increase the value of the variable and switch on a lamp to indicate that the variable is low. When the variable has increased sufficiently so that both vanes 10, 11 cut-off the light to both photo-cells, the relay is de-energized so that the variable is reduced and a lamp switched on to indicate that the variable is high. The transistor circuit is such that if the variable continues to increase until the photocells are illuminated again, the relay is not re-energized until the variable returns to the value at which the relay was energized. However, to ensure such operation, the pointer must be brought below the index whenever the control system is switched on, and an auxiliary transistor circuit, Fig. 3 (not shown), involving a resistancecondenser circuit, temporarily biases the pointer in the required sense under these conditions. Modifications involving different vane arrangements, more than one reference pointer, phototransistors, and thermionic valves are referred to.
