Patent GB-1141326-A (GB)
Title: Process for the manufacture of gases containing hydrogen and carbon monoxide
Inventor: REMAN GERRIT HENDRIK
IPC: C10K1/02
Filed: 1967-12-29
Abstract: 1,141,326. Making combustible gas. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 29 Dec., 1967, No. 59248/67. Heading C5E. Soot removed from gases made by partial combustion of a carbon containing feed is taken up in an auxiliary hydrocarbon oil and mixed with the incoming feed stream, this mixed stream is then subjected to a separating process to yield at least one stream of lighter hydrocarbons and a stream of residual material, which is heavier than the auxiliary stream used for taking up the soot, and which is used for the partial combustion process. The separating process used may be flashing (as used in Fig. 1), deasphalting (Fig. 2, not shown) or thermal cracking followed by distillation (Fig. 3, not shown). Deasphalting using propane as solvent yields a stream of propane soluble light fraction and a residue which may comprise a soft bitumen, or even a powder of dry asphaltenes, together with the recycled soot. The thermal cracking may be carried out at 500-550‹ C. and followed by a flash distillation. As shown in Fig. 1, a stream 2 containing the recycled soot is combined with the hydrocarbon oil feed stream 1 and passed through a furnace 3 and into a flasher 4 to yield a lighter fraction 5 and a heavier bottoms fraction 6, containing the soot, which is passed to the gasification reactor 7 together with oxygen 8. The soot is removed from the product gas 10 by washing with water in unit 11 and the soot-containing water is passed to unit 15, e.g. an agglomeration apparatus, where it is contacted with the auxiliary hydrocarbon stream. The auxiliary hydrocarbon may be a partial stream 17 of the hydrocarbon feed 1, a partial stream 18 of the light fraction 5, or a mixture of these. The soot contained in the stream 16 may be in the form of a slurry or of soft or of even hard pellets. In unit 19 the stream 16, especially if it consists of pellets, is mixed with more of the auxiliary hydrocarbon stream to form the suspension 2 of carbon in oil.

Title: Internal combustion engine valve actuator mechanism
Inventor: PRATT PHILIP GEORGE
IPC: F02D13/04
Filed: 1968-12-14
Abstract: 1279977 Valve gear VAUXHALL MOTORS Ltd 11 Dec 1969 [14 Dec 1968] 59568/68 Heading F1B An I.C. engine valve actuating mechanism for enabling the engine to act as a compressor during engine braking, has an exhaust valve cam (not shown) which is provided, in addition to the normal cam lobe, with additional cam surface arranged circumferentially to each side of the lobe, and the exhaust valve rocker 4 is mounted on an eccentric 5 carried by an angularly adjustable rocker-shaft 1. The rocker-shaft and attached eccentric shown are in position for normal engine operation. However, by angularly adjusting the shaft to the "brake" position as by a linkage or gear mechanism, the clearance between the end 7 of the rocker and the exhaust valve 3 is reduced so that the additional surfaces of the exhaust valve cam become effective to open the exhaust valve just before the end of the compression stroke, keep it open during the subsequent power and exhaust strokes and close it during the induction stroke. Angular adjustment of the rocker-shaft to provide the engine braking may be synchronized with mechanism to interrupt the engine fuel-supply or render the ignition system inoperative, or both.

Patent GB-1451650-A (GB)
IPC: G06V10/12
Filed: 1973-12-28
Abstract: 1451650 Photo-electric reading head DATA SOURCE CORP 28 Dec 1973 [5 Jan 1973] 59957/73 Heading G1A [Also in Division G4] A scanner associated with a character recognition unit has a number of detectors which view an area of a character-bearing surface taller than the character. The scanner which may be handheld, is moved over the surface, and circuitry is provided to connect to the recognition unit those cells that cover the character height, so compensating for misalignment of the scanner and the character. The scanner, Fig. 1, includes an array of photodetectors 24 which receive via light guides 22 the light reflected from the character-bearing surface, which may be flexible and uneven, such as a package. Light is directed on to the surface from a lamp 16 via light guides 20. The two sets of guides have their lower faces mounted in two parallel rows, Fig. 3 in a head 14. The head is pivoted about pins 54, 56 and is held a fixed distance from the surface by wheels 38, 40 which tend to guide the scanner in a straight line. There may be, for example, 24 detectors when the character height is equivalent to 11 detectors. In one embodiment, the detector outputs pass to a circuit, not described, which selects the relevant 11 detectors according to which of the 24 detects the top left hand corner of the character. The selected detector outputs pass to a recognition circuit via gating circuitry which gates together various adjacent detector outputs to compensate for small vertical wander of the scanner during reading of a character and provides signals indicative of the form of the character in 5 vertically spaced bands. In a second embodiment, Fig. 10 (not shown), the output of each detector is fed to a respective counter (112) incremented by clockpulses during scanning of black and reset to zero during scanning of white (background). If a counter reaches a preset count a corresponding bi-stable is set. The detector outputs, together with the outputs of the bi-stables, also pass to a logic unit which detects the vertical left hand, centre, and right hand zones of the character by detecting changes from black to white, or white to black, in the outputs of various of the detectors. In response to the three successive outputs of the logic unit the states of the bi-stables at these instants are read in to respective shift registers. The cells of the registers that correspond to the character are read out serially to circuitry which compares the signals with reference character signals for recognition.
