Title: Process for Preparation of 6-Amino-Penicillanic Acid and Salts thereof
IPC: C07D499/42
Filed: 1967-05-12
Abstract: 1,189,022. 6-Amino penicillanic acid, KONINKLIJKE NEDERLANDSCHE GISTEN SPIRITUSFABRIEK N.V. 12 May, 1967 [18 May, 1966], No. 22057/67. Heading C2A. 6-Aminopenicillanic acid is produced by protecting the 4-carboxyl group of a 6-acylaminopenicillanic acid, reacting the latter to form an imino bond therein, reacting the latter to introduce an -OR group on the imino carbon atom, wherein R is C 1  to C 12  alkyl or C 7  to C 14  aralkyl, to form an imino ether and reforming the free 4-carboxylic acid, and splitting the imino bond of the imino ether to form the 6- amino penicillanic acid. The penicillin is preferably one produced naturally by fermentation, e.g. benzyl penicillin and phenoxymethyl penicillin. The 4-carboxyl group of the penicillin is protected by esterification particularly with a silylating agent such as trimethyl chlorosilane. Formation of the imino bond is preferably by means of an acid halide, especially phosphorus pentachloride or phosphorus oxychloride, in the presence of a tertiary amine, e.g. pyridine. The imino halide is reacted with an alcohol, e.g. methanol in the presence of a tertiary amine such as pyridine, to produce an imino ether and, in the case of the 4-silyl ester, to simultaneously produce the free carboxylic acid. The 6-aminopenicillanic acid is recovered by hydrolysis of the imino ether with excess alcohol and hydrogen ions. If aralkyl esters such as the benzyl ester are used for protecting the 4-carboxyl group, the 6-aminopenicillanic acid benzyl ester produced by the hydrolysis of the imino ether is subjected to hydrogenolysis to free the 6- aminopenicillanic acid. The imino bond may also be produced by treatment with triethyl oxonium tetrafluoroborate, followed by pyridine to form the imino ether. Specification 1,041,985 is referred to.

Title: Oscillating lawn sprinkler
IPC: B05B3/16
Filed: 1964-05-28
Abstract: 1,067,218. Spray-producers; lawn sprinklers. R. KOWK. May 28, 1964 [Feb. 14, 1964], No. 22065/64. Heading B2F. In a water driven oscillating lawn sprinkler 10, Figs. 1, 2 the gearing by which a perforated tube 25 is oscillated is housed in the chamber through which the water to be sprinkled passes to the tube inlet 27 after entering the sprinkler through a hose connection 15. Whilst passing through the chamber the water turns a water wheel 20 which drives a worm gear 20a integral therewith which in turn, rotates a spur gear 23 integral with a further worm gear 23a. The latter rotates a spur gear 24 which causes through a lever 39, a link 40 and a further lever 38, oscillation of a casting 26 integral with the tube 25. The amplitude of the coating, and hence that of the tube, may be adjusted through actuation of a rotatable knob 33 which in effect alters the fulcrum of the lever 38, whilst built in at the bearing end 14 of the sprinkler is a spike, which may be removed when required through actuation of a knob 31 for "knocking-out" the tube orifices 25a for cleaning purposes.

Title: Improvements in or relating to photographic shutters having built-in flashlamp synchronisers
IPC: G03B9/70
Filed: 1950-09-07
Abstract: 686,136. Photographic shutters with built-in flashlamp synchronizers. KODAK, Ltd. Sept. 7, 1950 [Sept. 7, 1949], No. 22128/50. Class 98 (i). A photographic shutter comprises bladeoperating means, an exposure speed control member adjustable to vary the speed of operation of a part of the blade operating means, and a flashlamp synchronizer including a normally open switch closed by a part of the blade operating means in timed relation to the opening of the blades to accommodate the lag of the flashlamp, wherein said switch is operatively connected to the speed. control member so that it is adjusted by movement thereof to alter the time of closing of the switch relative to the blade opening movement, thereby ensuring that maximum use is made of the total illumination provided by the lamp. As shown, a photographic shutter as described and claimed in Specification 650,874 combined with a built-in flashlight synchronizer as described and claimed in Specification 661,869, is modified in accordance with the present invention by securing a cam 300 to the exposure adjusting ring 301 operable by means of its notched edge. Cam 300 engages a tail 201 controlling the position of the adjustable insulated contact of the synchronizer switch when the synchronizer ring 100 (Fig. 4, not shown), located beneath the exposure adjusting ring 301 is set for use with lamps having a lag of about 20 milliseconds. Said ring has cam edges controlling the position of said tail for different lamp lags. When the synchronizer ring is set for lamps of shorter lag, the tail 201 is moved clear of the cam 300 by other cam edges on the ring. If desired, a further cam similar to 300 may be attached to the exposure speed adjusting ring for lamps having lags of 5 milliseconds but this is usually unnecessary since such lamps have a sharply peaked emission. Specification 571,030 also is referred to.

Abstract: 690,574. Dressing grinding wheels. HALLEWELL, H. S. Aug. 24, 1951 [Sept. 8, 1950], No. 22240/50. Class 60. A grinding wheel dressing device includes a pantograph wherein one member 24, Figs. 1 and 3, is forked at one end, while another member is constituted by two links 18, 18A, Fig. 2, having their upper ends pivoted respectively to the two prongs of the fork, the dressing tool holder 27 extending between two bearings 31, 31A respectively in the two prongs. The other two members of the parallelogram consist of a tubular lever 21, Fig. 3, carrying a rotatably-mounted tracer at its free end and a H-section link 17 pivotally connected at 19 to a base-plate 10 adapted to be engaged by a magnetic chuck on the grinding machine. The base plate is forked in a similar manner to the member 24 in order to provide pivotal connections for the lower ends of the links 18, 18A. The member 24 is made as a light alloy casting of inverted channel section and with boxed-in ends to protect the bearings between the links. The tool-holder 27 is secured by bolts 33, Fig. 2, to shafts 29, 29A mounted in ball-bearings, one set of which is free to move axially to accommodate changes in length due to temperature variations. The diamond 37 has a chisel-shaped end and is adapted to be adjusted vertically by a screw 39 and horizontally by a screw 40 acting through a lever 41. Each end of the holder 27 has a slot 35, 35A provided with three radially.- disposed grub screws which enable the holder to be adjusted with respect to the shaft centres. Sector blades 51, Fig. 3, restrict the angular movement of the tracer which is connected by spring-tensioned tapes 46, 47 and an intermediate pulley 48 with the tool-holder. Slip between the tapes and the intermediate pulley is prevented by grub screws 50. The weight of the pantograph is partly supported by springs 52. A second diamond for rough trueing may be added to the tool-holder. A support 13 carries the template which is located by a straight edge 15 and a stop 16. Specification 573,877 is referred to.

Abstract: 336,684. Harris, A. W. July 23, 1929. Securing flywheels on shafts.-In the trans mission train from a prime mover to a gramophone turntable, a massive element smoothes out the relatively small vibratory variations in the driving effort by the effect of inertia and a resilient coupling smoothes out the relatively large vibratory variations, the resilient coupling being rigid when transmitting torques below a given amount. The drive from the prime mover is transmitted by a worm 3 and worm-wheel 4. The latter has two pins 5 passing through arcuate slots 6 in a flywheel 1. The upper face of the flywheel 1 has a circular channel 7 in which two pairs of blocks 8 are slidable, the blocks of each pair being forced towards one another and against stops 9 on the flywheel 1 by springs 10. The end of each block 8 adjacent each pin 5 has a semi-circular recess to clear the pins. For torques below a given amount the coupling transmits solidly, the blocks 8 remaining hard up against the pins 5. When the torque increases above the given amount the normal tension of the springs is exceeded and the coupling becomes resilient.
