Patent GB-862159-A (GB)
Title: Potassium phenoxymethyl penicillin
Inventor: JONES WILLIAM NORMAN
IPC: C07D499/60
Filed: 1958-09-19
Abstract: Potassium phenoxymethylpenicillin in the form of needle-shaped crystals is produced in high yield by dissolving solid free phenoxymethylpenicillin of at least 90% purity and preferably of at least 95% purity, in a lower alkanol containing 2 to 4 carbon atoms, or an alkyl acetate or ketone containing not more than seven carbon atoms, mixing the resulting solution with potassium acetate, adjusting the water content of the mixture to within the range of 1 to 5% by volume and thereafter separating the crystals of potassium phenoxymethylpenicillin.  The potassium acetate is preferably used in excess and is preferably dissolved in water, the solution of phenoxymethylpenicillin in the organic solvent being added to the aqueous solution of potassium acetate.  Maximum yield is obtained at 0 DEG  C., but it is preferred to mix the solutions at 28 DEG  to 30 DEG  C. and then to reduce the temperature to 18 DEG  to 20 DEG  C. during crystallization.  The preferred solvent is isopropanol but others which may be used are acetone, methyl ethyl ketone, ethyl acetate, propyl acetate, butyl acetate and amyl acetate.

Title: Improvements in the catalytic treatment of hydrocarbons
Filed: 1939-11-15
Abstract: 540,287. Cracking hydrocarbons ; catalysts. STANDARD OIL DEVELOPMENT CO. Nov. 15, 1939, No. 30128. Convention date, Dec. 23, 1938. [Classes 1 (i) and 32] [Also in Group IV] In processes for the catalytic conversion of hydrocarbons, e.g. cracking, desulphurization, de-hydrogenation, hydrogenation, polymerisation, reforming &c. of the kind in which the catalysts are re-generated periodically in between successive reactions, the length of the catalytic treatment between re-generations is reduced as the activity of the catalyst depreciates. A plurality of independent conversion zones may be used alternately "on stream" and undergoing re-generation. Alternatively, when the process includes purging stages, before and after the re-generation stage, to remove residual oil products and the products of regeneration, the lengths of the conversion, purging, and re-generation stages are correlated to maintain a constant time ratio, e.g. time ratio between the purging, cracking and re-generating cycle of the order of 1:2:3. Cracking stock vaporized in a heater 12 is passed through a manifold 15 to any or all of a series of reaction chambers 23-28 filled with catalyst, e.g. natural or activated clays, synthetic alumina or silica gels. The cracked products are withdrawn through lines 30-35 and manifold 36, 37 to fractionating tower 38 from which vapors of desired boiling range are recovered through line 44 while heavier fractions are recycled through line 42. Each pair of reaction towers 23, 24 &c. is provided with separate re-generating and purging arrangements. The regenerating gas, e.g. air, is admitted through lines 53, 56 and removed through lines 30, 31, manifold 57 and lines 58, 59. part being recycled through line 61 and heat exchanger 62 if desired. The purging gas, e.g. steam, is admitted through lines 99, 86, 87, and removed through lines 92, 93. Various different arrangements of the reaction tower to give the requisite periods "off" and "on stream" are described.

Abstract: 477,187. Seat frames. BRIGGS MANUFACTURING CO. Nov. 5, 1936, No. 30144. Convention date, Dec. 5, 1935. [Class 52 (ii)] A seat for motor vehicles &c. comprises a frame consisting of two members A connected by a transverse tiemember C, preferably in the form of a rearwardly - opening trough serving as a foot rest for use of the occupants in the seat behind.

Title: An improved internal-combustion engine having more than one piston acted upon by thesame impulse
IPC: F02B37/02
Filed: 1939-11-15
Abstract: 541,518. Two-stroke engines with variable compression ratio. SAMPIETRO, A. C. Nov 15, 1939, No. 30150. [Class 7 (ii)] Pairs of cylinders having a common combustion head 28 are geared to crank-shafts resiliently geared to each other. Under light loads the exhaust controlling piston 31 leads the other by about 30 degreesof crank-angle. The spring gearmountings are of unequal stiffness so that while on light loads the compression ratio is a maximum, under heavier loading the mountings give unequally, increasing the lead of one piston relatively to the other and thus reducing the compression ratio. An exhaust-driven turbine 46 drives a blower 57 which comprises twin impellers arranged back to back. Excess air in the exhaust, particularly when the compression ratio is reduced, is used to increase the turbine output. Additional fuel pumps 99, controlled by a lever 106, and injecting into each exhaust pipe are provided for this purpose. Compression-ratio adjustment may be non- automatic through an electrically-controlled servomotor. One of the crank-shafts is connected to its gear-wheel 70a, Fig. 11, through helical grooves between the shaft and an intervening bush 120 and axially parallel grooves between the bush and gear wheel. Bevel gearing connects the bush to an electric motor 155. controlled either manually or automatically through slip rings.

In a rake-wheel type of side-delivery rake the main frame comprises two rakewheel-carrying limbs 40, 42 parallel but not collinear, and extending oblique to the direction of travel, the limbs being integrally interconnected by a relatively cranked portion 41 which carries one of the two ground-wheels 50 by which the frame is supported, the other ground-wheel 47 being carried at the end of a beam 43 projecting from the cranked portion at right angles to the direction of travel. The ground-wheels are mounted on vertical swivel-pins 45, 48 and are interconnected by a track-rod 52 for adjustment in unison. A drawbar 58 is pivoted about a vertical pin 59 to a lug 57 on the beam 43, and can be held at various angles thereto. The beams 40, 42 each carry a group of three rake-wheels 64, 70 mounted on cranks 63, 69 which are interconnected for movement in unison by a rod, 66 or 72, linking them. Each rod is connected, by a flexible connection 82, 83, to a lever 76 pivoted on the frame and movable by a hydraulic ram 79 connected by flexible conduits to the hydraulic system of the towing tractor (not shown). In Fig. 5 the rake-wheel-carrying beams are composite and comprise limbs 104, 106 of inverted channel-section with circular-section beams 125, 133 mounted within them and secured thereto by bolts 126, 134. The rods 132, 139 joining the cranks of the two rake-wheel groups are connected by cables 163, 166 to two arms 161, 162 of a three-armed lever, the third arm 159 being connected to a rod 142 movable longitudinally either by a hand-crank 144 or by a hydraulic ram 154, both adjusting devices having a lost-motion connection with the rod enabling them to be mutually independent. A further handcrank 169 adjust the ground-wheels 112, 114 about their swivel-pins.
