Title: Phosphonium salts and corresponding phosphoranes
Inventor: OPENSHAW HENRY TACON
IPC: C07F9/62
Filed: 1963-12-09
Abstract: The invention comprises compounds con taining the cation of the Formula (I) <F\1> and the corresponding phosphoranes derived therefrom of the Formula (II) <F\2> wherein R0, R1 and R2 represent hydrogen atoms, or an additional double bond is formed in the absence of either R0 and R1, or R1 and R2 between C(3) and C(1), or C(1) and N(2) respectively, R3 and R4 are each a lower alkoxy group, having from 1 to 4 carbon atoms, and each of B1, B2 and B3 is an alkyl, phenyl or substituted phenyl group.  The compounds containing the cation of Formula (I) are pre pared by reacting a compound of the general Formula (III) <F\3> wherein R3 and R4 are as defined in Formula (I), A is the anion of a strong acid, e.g. hydrochloric or sulphuric acid, and X is a chlorine or bromine atom, with a substituted phosphine of the formula <F\4> in a substantially anhydrous polar solvent in which both reactants are appreciably soluble, e.g. nitromethane, acetonitrile and chloroform. The product may be isolated as an acid addi tion salt of the Formula (V) <F\5> or can be converted into phosphonium salts of the Formula (VI) <F\6> by treatment with a weak base, such as am monia, and either of the phosphonium salts of Formula (V) and (VI) may be reduced cata lytically with hydrogen or with a reducing agent such as metal borohydride to the corre sponding saturated phosphonium salts of the formula <F\7> or an acid addition salt thereof.  The corre sponding sponding phosphoranes of Formula (II) may be prepared from phosphonium salts containing the cation of Formula (I) by reaction with strong bases such as sodamide or the sodium derivative of dimethyl sulphoxide.  The above phosphonium salts and phosphoranes are useful as intermediates in the synthesis of pharmacologically active compounds. Examples describe the preparation of 1-p-chlorostyryl-3,4-dihydro-6,7-dimethoxyisoquinoline and of the 1,2,3,4-tetrahydro derivative from the corresponding phosphoranes by reaction with p-chlorobenzaldehyde.  On reduction of the 1,2,3,4-tetrahydro derivative followed by N-methylation, a known analgesic is formed.  An example also describes the preparation of 2-dehydro-O-methylpsychotrine by reacting a 3,4 - dihydro - 6,7 - dimethoxy - 1 - isoquinolylmethylene phosphorane with 3 - 1,2,3,4,6,7 - hexahydro - 9,10 - dimethoxy - 2 - oxo - 11bH - benzo(a)quinolizine.

Title: Radar signal processing systems
IPC: G11B20/02
Filed: 1971-10-20
Abstract: 1390037 Multiplex systems; radar FERRANTI Ltd 19 Oct 1972 [20 Oct 1971] 48701/71 Headings H4R and H4D Three video signals are combined for recording on a video tape recorder by modulating two of the signals on respective carrier signals of the same frequency but in quadrature phase relation and adding the resulting signals to the third video signal. As described the video signals are the transmitted pulse T and echo pulse E of radar sets. The transmitted pulse and echo pulse are combined in signal processors CE1-CE3, e.g. by adding the transmitted pulse in antiphase to the echo pulses. The resulting signals are band limited in filters F1 to F3 and the signals from channels 2 and 3 modulate, in balanced modulators BM2 and BM3, quadrature related carrier signals of 3À5 MHz before being added to the channel 1 signal in combiner CM1. The combined signal frequency modulates a carrier from generator G2 over a range of 5À5 to 6À6 MHz, and a pilot signal, derived by frequency division of the carrier from G1 down to 1 MHz, is added at CM2 before the signals are recorded. For reproduction Fig. 3 (not shown) the pilot signal is separated out by a filter and multiplied up to provide a carrier for demodulation of the quadrature related channel 2 and channel 3 signals, which are separated from the channel 1 signal by respective high and low pass filters. Bearing information and audio signals are recorded on the 2 audio tracks of the video recorder by having the bearing and marker information frequency modulate carriers for the three respective video signals and transmitting one bearing and marker signal together with audio signals on one recorded audio channel and with the other two bearing and marker signals on the other recorder audio channel, Fig. 4 (not shown).

IPC: H04M1/34
Filed: 1968-10-16
Abstract: 1,239,038. Impulse generators. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Oct., 1968 [25 Oct., 1967], No. 49005/68. Heading H4K. Lost motion is provided in a telephone dial mechanism by rotating a member with the impulsing cam which member engages a part of the impulsing spring set until the latter is moved as a whole by the cam to release the member which rotates until it engages the spring set again when rotation of the cam causes the impulsing contacts to be operated. When the dial is set, cam B is driven anticlockwise and the lost motion member rotates with the cam until projection C engages contact operating arm E. On release, cam B and the member rotate clockwise until projection D engages short contact arm A and the member stops (Fig. 2). Further rotation of cam B pushes arm E downwards to push the closed contacts A out of engagement with projection D so the member rotates again until projection C engages long contact arm A. On further rotation of cam B, the contacts are pushed downwards so that projection C engages the short contact arm A and the contacts open as the cam rotates further. In a modification, Fig. 7, the first engagement is made by arm 3 on the lost motion member which engages extension 4 on operating arm 10 until it is disengaged by upward motion of the eccentrically mounted lost motion member which is then rotated to the position shown for impulses to be produced. Additional pauses in the pulse train are produced by cam 7, mounted on the dial shaft, which moves projection 2 away from contact spring 5.

Title: Apparatus for preventing drunken driving of a motor vehicle
IPC: B60K28/06
Filed: 1972-10-24
Abstract: 1401319 Preventing drunken driving HONDA GIKEN KOGYO KK 24 Oct 1972 [27Oct 1971] 49055/72 Heading G1N [Also in Division B7] Alcohol exhaled by a vehicle driver is detected by a device which prevents the vehicle being driven, e.g. by breaking the ignition circuit. In Fig.3 the detector 2 is a heated platinum wire mounted on the steering wheel hub and is fed from D.C.-A.C. converter 3; alcohol vapour burns on this wire, so changing its temperature and its resistance. When the resistance changes the potential at tap 4a of potentiometer 4 also changes and switches on transistors 6 and 7. Relay 8 thus operates to illuminate lamp 10, which may be visible from outside the vehicle, and to break the ignition circuit 9. This relay is held on by contact 8c operated by relay 14. If a sober person now tries to drive the vehicle, transistors 6 and 7 are switched off as detector 2 returns to its initial resistance, but capacitor 11 keeps transistor 13 on for a predetermined time. At the end of that time contact 8c is opened and the vehicle becomes drivable again. This time delay prevents the ignition switching on and off as the driver breathes in and out.

Abstract: 1337219 Dual lane packaging machine REXHAM CORP 26 Oct 1972 [12 Nov 1971] 49410/72 Heading B8C A dual lane packaging machine includes a carriage 60, driven rollers 37 on the carriage for advancing a strip 35 of interconnected open-ended pouches along a predetermined path, means to reciprocate the carriage laterally of the path between two laterally spaced pick-up stations, and a cutter 36 on the carriage to sever the leading pouch after it has been received in a pick-up station. A web 27 is unwound from a roll 26 by a roller 205 biased against the roll 26 by a counterweight and driven by a drive shaft 50 through a one-way clutch and an adjustable gear-box. The roller 205 unwinds slightly less strip than is required for each pouch, the excess being pulled from the roll 26 by the rollers 37. The web advances via dancer rolls 29, 30 and plough 31 to transverse sealing bars 33 which form the web into a strip of pouches. The rollers 37 are intermittently driven with the strip being braked when an electric eye 94 senses a mark 95 on the web. Slack in the strip just upstream of the carriage as the carriage moves into the mid-position between the pick-up stations is taken up by a roller 99 moving against the strip. Splitter bars on the carriage extend into the strip to keep the top of the pouches open. One bar is pivoted out of the way as the cutter 36 closes. A chain 44 has pairs of clamps 53, 54 to intermittently advance pairs of pouches to filling heads 41 and sealing station 43. The clamps of each pair are successively opened at the pick-up stations by actuators 139, 140 pivoted by cams 146 on the shaft 50. Fixed splitter bars 115 extend downstream from the pick-up stations. At the sealing station there is a pair of sealing bars for each lane of pouches, one bar of each pair being mounted on an arm 174 and the other bar of each pair being mounted on an arm 175. Spring 180 and cams 179 on the shaft 50 control the swinging movements of the arms and thus of the sealing bars.
