Abstract: 1479174 6-Aminopenicillanic acid 1-oxide and salts thereof SHIONOGI & CO Ltd 20 Sept 1974 [21 Sept 1973] 41120/74 Heading C2C 6-Aminopenicillanic acid 1-oxide or a salt thereof is obtained by subjecting a penicillin 1-oxide or salt thereof to the action of a penicillin 1-oxide amidase-producing microorganism belonging to genus Streptomyces, or of a penicillin-1-oxide amidase preparation derived therefrom. Specified penicillin 1-oxides are the oxides of penicillin G and penicillin V. The penicillin- 1-oxide amidase preparation may be in the form of a propagated microorganism-containing culture broth, a mycelium, a culture broth free from the microorganism but in which the microorganism has been cultured or an enzyme solution. The product is useful in the preparation of synthetic penicillins and cephalosporins. Penicillin V-1-oxide, carbenicillin 1-oxide and the sodium salt of penicillin G-1-oxide are each obtained by treating 6-aminopenicillanic acid 1-oxide with phenoxyacetyl chloride or phenyl chlorocarbonyl ketone or by treating the trimethylsilyl ester of 6-trimethylsilyaminopenicillanic acid 1-oxide with phenyl acetyl chloride repsectively.

Abstract: 930,420. Chucks. BIRMINGHAM SMALL ARMS CO. Ltd. Dec. 5, 1960 [Dec. 4, 1959], No. 41183/59. Class 83 (3). A chuck comprises a casing 1 having jaws 4 slidable in grooves 2, an endless track 6 in which blocks 7 having grooves 8 for engagement with teeth 9 on the jaws are slidable, and an annular member 10 rotated by pinions 15 which cooperate with teeth 14 on member 10 for moving the blocks along the track to move the jaws radially. The track has straight portions bisected by each jaw, which are joined by curved portions, is symmetrical of the casing, and breaks through into grooves 2, and the blocks can slide completely round the track. The grooves 8 in the blocks are inclined so that if the blocks were placed end to end they would move through one pitch.

Abstract: 1,197,459. Automatic speed control. ERESA S.A. Sept.19, 1967 [Sept. 29, 1966], No. 42635 / 67. Heading G3R. An electric motor M is controlled from a source 1 which supplies a reference signal whose frequency represents the desired speed of the motor, an alternator 2 being driven by the motor to supply a signal the frequency of which is proportional to the actual speed. The phase relationship between the two signals is detected to form two position signals which are equal when the motor is in a required angular position. When starting, the motor is accelerated until the two speed signals are equalized, the motor being then controlled by the difference between the position signals which determines the magnitude of the applied voltage. The amplitude of a signal t varies in dependence upon the frequency of the motor signal m, and in accordance with the adjustment of potentiometer R. A differential amplifier 5 compares the signal t with a reference signal to, the error signal C being amplified to control the supply to the motor. A phase control circuit 7 derives position signals P2, P1, from the motor signal m and the reference signal f supplied by the source 1. The signals P1, P2, are equal when the frequencies of the signals m, f, are identical, and these two signals are 90 degrees out of phase. The signals P1, P2 are respectively superimposed on the signals to, t, before they are applied to the comparator circuit 5, and become predominant when the speed approaches the desired value. In another arrangement, the reference signal f is made to vary with time, this signal being fed to a trigger circuit in series with a monostable multi-vibrator and an integrator the output of which is the signal to whose magnitude varies in accordance with the frequency of the signal f. A similar network supplies the signal t in response to the input signal m, Fig. 2 (not shown). An alarm device is energized if one of the signals m or f is blocked, and a relay is deenergized to stop the motor, Fig. 3 (not shown).
