[Class 98 (i)] The photo - electric cell 3 is attached to an arm 9 integral with the diaphragm ring 1 of the camera lens 5. A diaphragm formed from a plate 6 with a wedge shaped aperture 8 is attached to an arm 7 integral with the shutter speed adjustment 4. Specification 395,808 is referred to. The Specification as open to inspection under Sect. 91 describes also a number of forms of camera with exposure meters in which the meter pointers and co-operating fiduciary marks are visible in the view-finder fields. In the form shown in Fig. 6 (Cancelled), the shutter speed ring 36 is connected by a gear 35 to the adjusting ring 33 of a diaphragm mounted in front of the photo-electric cell 28. The gear 35 may be disengaged and the two members set relatively to one another to take account of different film speeds. The diaphragm ring 16 is geared to a pivoted cradle in which the coil of the meter is mounted, the outer ends of the controlling hair springs being attached to posts 22 on the ends 19 of the cradle. In an alternative arrangement, the whole of the meter, including the magnet, is mounted in such a cradle. In another camera which is described, the diaphragm and shutter speed adjustments are both coupled to a variable magnetic shunt on the magnet of the meter. The magnet is a horseshoe, and its limbs are bridged by a piece of soft iron. The effect of this on the magnetic field in which the coil is situated is varied by moving it closer to or farther from the polepieces. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electromagnetic wave switching arrangements
IPC: H01P1/11
Filed: 1957-08-20
Abstract: 848,113. Waveguide switches. GENERAL ELECTRIC CO. Ltd., and WALSH, A. S. Aug., 20, 1958 [Aug. 20, 1957], No. 26330/57. Class 40(8). [Also in Group XL(c)] Two transmission paths, e.g. waveguides 1, 2, are coupled at spaced points by directional couplers 3, 4, a 180 degree non-reciprocal phase-shifter 7 being inserted in one of the paths between the couplers. The couplers are of the type which effect an equal division of input energy between two outputs, the two outputs being in phase quadrature. They may be of the branched-guide or long slot type. If the magnetic field controlling the phase-shifter 7 is set to change by 180 degrees the phase of waves travelling from left to right in the guide 1 and to have no effect on waves travelling in the opposite direction, then it may be seen that, taking into account the 90 degree phase-shift inherent in the couplers 3, 4, total coupling of energy is effected from terminal A to terminal B, from B to C and from D to A. Reversal of the magnetic field in the phaseshifter 7 causes reversal of its properties. Under these conditions the coupling directions are:- A to D, D to C and B to A. The non-reciprocal phase-shifter 7 is of the known type using a slab 24 of ferrite asymmetrically disposed in the guide 1, a polythene member 28 being disposed in the other guide 2 to equalize the electrical lengths of the guides. The reversible magnetic field is generated by a solenoid associated with a commutator. When the arrangement is used as a duplexer, terminal A (the transmitter terminal) is provided with an isolator 9.

Title: Method of preparing 5'-ribonucleotides
IPC: C07H1/02
Filed: 1965-06-23
Abstract: 51-Ribonucleotides are prepared by reacting the corresponding 21,31-O-protected ribonucleoside with phosphoryl chloride or tetrachloropyrophosphate in the presence of a trialkyl phosphate, hydrolysing the resulting 21,31-O-protected ribonucleoside phosphoro-di-chloridate and then hydrolysing the resulting 21,31 - O - protected - 51 - ribonucleotide to remove the 21,31-O-protecting group.  The reaction may generally be effected at a temperature of from -15 DEG  to 25 DEG  C. and the dichloridate is then hydrolysed with water at a temperature below 30 DEG  C.  The trialkyl phosphate, e.g. trimethyl phosphate, triethyl phosphate, tripropyl phosphate, tri-n-or tri-iso-butyl phosphates is preferably employed in an amount of at least one mole equivalent per mole of nucleoside.  Suitable starting materials are purine ribonucleosides such as adenosine, xanthosine, guanosine and inosine, pyrimidine ribenucleosides such as uridine and cytidine and ionidazole ribonucleosides such as 5 - amino - 4 - carbamoyl - 1 - b - g  - ribofuranosyl imidazole, in which each of the 21 and 31-positions are protected by acyl groups such as acetyl or benzoyl, or by alkylidene groups such as isopropylidene or cyclohexylidene.  The 21 and 31 O-protecting groups may be split off by conventional means, e.g. with dilute acid.

Abstract: 818,407. Dial gauges. INSTRUMENTAKTIEBOLAGET METRON. Aug. 31, 1956 [Aug. 31, 1955], No. 26717/56. Class 106 (2). A dial gauge comprises a feeler stem 14, a transmission member 24 movable relative to the stem 14 and urged away from the feeler tip 50 by a spring 48, the member 24 transmitting through a transmission system 26, 30, 32 movement of the stem 14 to a pointer 20, and the stem 14 carrying a movable abutment 54 against which the member 24 is pressed by the spring 48; means being provided to move the abutment along the stem 14, without rotating the latter, to set the pointer to zero. A pin 44 passes through slots 40 in the stem 14, and into a recess 46 in the casing 10 to limit movement of the rod 14, and is fixed in the transmission member 24. It is held between a screw 54 and a ball 56 by the spring 48, the screw 54 being used to adjust the initial position of the pointer 20. A band 26 is attached to the transmission member 24 and drives a band drum 28 to which is attached a toothed segment 30 driving a pinion 32 carrying the pointer 20. Fig. 5 shows a restoring spring 60, which is attached at 62 to the casing 10 and at 66 to a toothed segment 68, turnable relative to the segment 30. This eliminates tooth play between the gears and provides an approximately constant restoring force. An alternative method of achieving this by means of two springs and only one toothed segment is also described. The spring 60 may also be arranged with one or more loops in it to provide a more constant restoring force. To allow for slight inaccuracies in the diameter of the drum 28, the ends 72, 92 of the band 26 are provided with slots 84, 86 and 94, Fig. 7, so that the band may be effectively lengthened and one end adjusted in a direction transverse to its length. Alternative methods of connecting the band 26 to the segment 30 are shown and also a method of increasing the transmission ratio, Fig. 8, using two bands acting on a segment 96 with different sized drums between the transmission member 24 and the toothed segment 30. The spring 48 acts as a shock absorber, and the inability of the stem 14 to turn, due to the pin 44 in the recess 46, makes this instrument suitable for use when the measuring feeler is chisel-shaped or is in the form of a laterally protruding arm for internal measurements. The segment 68 may also carry a pointer 22 to indicate the number of revolutions of the main pointer 20.
