Title: Method of and apparatus for testing a bottle
IPC: G01N21/90
Filed: 1969-08-06
Abstract: 1278491 Inspecting bottles for blemishes photo-electrically MITSUBISHI JUKOGYO K K 6 Aug 1969 [7 Aug 1968] 39443/69 Heading G1A [Also in Division G2] In a method of testing a bottle, light received within the bottle is divided into a number of separate channels and then converted into separate electrical signals, these signals being amplified and supplied to circuitry including an OR-gate 23 so as to detect the presence or absence of foreign matter on the surface of the bottle. The instrument shown in Fig. 1 is located inside a bottle, and light is deflected by a mirror 7 and focused by a lens 6 on to one end of an optical fibre bundle 4, the other end of the bundle being divided into three separate spaced sections 4a, 4b, 4c. Between each of these sections and its corresponding photoelectric transducer 10a-c is located a glass plate. As shown in Fig. 6, associated with each transducer is an amplifier 20a-c, an integrator 21a-c and a shaping circuit 22a-c. Subsequent to the shaping circuits are an OR gate 23, an AND gate 26 and a memory circuit 27. A branch circuit from transducer 10a to the OR gate contains a D. C. amplifier 24. The second input to the AND gate is connected to a trigger circuit 25, which produces a gating pulse during the inspection period of each bottle. A reset pulse generator 28 is provided for resetting the memory circuit. In use, the bottle is rotated while the inspection device is raised or lowered, to scan the side surface of the bottle in a spiral manner. When a blemish is scanned, at least one of the transducers will produce a pulse which, in modified form, is fed to AND gate 26 to operate a reject mechanism. If the entire surface of the bottle is covered with foreign matter, the transducers detect no change in light level, and hence they produce no reject signal. However, in this case the D. C. amplifier 24 is arranged to provide an output whenever transducer 10a does not produce an output and hence this amplifier generates a reject signal.

Title: Process for preparing penicillin sulphoxide
IPC: C07D499/60
Filed: 1973-08-21
Abstract: 1388979 Preparing penicillin sulphoxides ELI LILLY & CO 21 Aug 1973 [12 Sept 1972] 39603/73 Heading C2C Penicillin sulphoxides are prepared from a penicillin-containing fermentation broth by filtering off the mycelium and adding a miscible organic liquid to the filtrate to precipitate non- penicillin impurities, oxidizing the penicillin in the solution with a per-acid oxidizing agent at -20 to 25 C., to produce the sulphoxide, lowering the pH of the resulting solution and adding water to induce crystallization of the sulphoxide, and separating the crystallized sulphoxide from the supernatant. The filtered broth containing the penicillin (e.g. phenoxymethyl- or benzyl-penicillin), is preferably concentrated to 200-400 mg. solid per ml. before adding the organic liquid, which is preferably acetone in ¢-3 volumes or may be methanol, ethanol, methyl ethyl ketone, acetonitrile, isopropanol, tert.-butanol or propionitrile. The precipitated impurities are usually filtered off, and if desired the organic liquid may then be removed. Oxidation is effected with an at least partially soluble oxidizing agent, in sufficient amount to convert all the penicillin content to the sulphoxide, e.g. 1-3 moles per mole of penicillin; the preferred agents are per-acetic acid, per-propionic acid, per-benzoic acid and per-succinic acid. The pH is then lowered to a crystallization point of the penicillin (i.e. about the iso-electric point), usually about pH 1À5-2À5, preferably with one of the following: methanesulphonic, p-toluenesulphonic, hydrochloric, sulphuric, o-phosphoric or nitric acid, and water is added to assist crystallization. The penicillin oxide crystallizes in pure form and is separated from the supernatant liquid.

Abstract: 1398264 Fuel injection pumps; regulating I C engine fuel injection D BASTOW 31 Aug 1972 [2 Sept 1971] 40881/71 Headings F1A and F1B The fuel delivered by a rotary distributor radial cylinder fuel injection pump is varied in accordance with engine speed by a centrifugal governor 47-49 and also in accordance with engine inlet air pressure or temperature, the governor controlling the eccer tricity of a non-rotatable track 16 with which the pump's pistons 14C co-operate. Both the pump and the governor are driven by a shaft 6. With increasing shaft speed governor balls 49 move radially outward to cause axial movement of a thrust pad 51. This movement is converted into eccentricity adjustment of the track through a bifurcated lever 55, a link 57 and an axial cam 53 loaded by a spring 50. The cam 53 bears against a roller 62 and displaces the track 16 against the bias of a spring 54. To compensate for changes in engine inlet air temperature and pressure, the roller 62 is mounted on a lever 76 adjustable in accordance with these variables. Thus the lever 76 is pinned at 75 to a lever 74 the angular position of which, about a pivot pin 78, is controlled by expansion and contraction of a fluid filled bellows 72 responsive to engine inlet air temperature. Similarly the angular position of the lever 76 about its pivot 75 is dependent on a bellows arrangement, Fig.6 (not shown) which compares the inlet air pressure with the ambient air pressure compensated for changes of the latter. For calibration purposes the pivot pin 78 is eccentrically mounted on a lever 82 angularly adjustable by a screw 83. A gear pump 24 driven by the shaft 6 supplies fuel to the pump cylinders 13a, (13b) 13c &c. through passages 43, 25 in the shaft and a longitudinal passage 19 in a spigot 12 about which the pump cylinder block 10 rotates. Each cylinder supplies an individual outlet, Figs.2, 3 and 4 (not shown). Leaked fuel collects in a sump 5 containing a float 86 which when lifted a predetermined amount opens a valve (93) in a passage connecting the sump to the suction side of the gear pump 24, Figs.7-9 (not shown).
