Abstract: 1298214 19-Norsteroid synthesis F HOFF. MANN-LA ROCHE & CO AG 20 Nov 1969 [22 Nov 1968] 56793/69 Headings C2C and C2U The invention comprises the preparation of d-, l- and dl-19-norsteroids of partial Formula (I) by three routes from d-, l- and dl-19-isoxazolyl-de-A-steroids of partial Formula (II) wherein R<SP>2</SP> and R<SP>3</SP> are identical C 1-8  alkyl groups or one of R<SP>2</SP> and R<SP>3</SP> is H and the other is C 1-8  alkyl, and R<SP>4</SP> is H or a C 1-7  alkyl group having one CH 2  group less than R<SP>2</SP> or R<SP>3</SP>. Route 1 comprises hydrogenation of (II) to yield a 4-azagon-2-ene of partial Formula (A) treatment of which with an anhydrous strong base yields a 4-azagona-2,5(10)-diene of partial Formula (D) hydrolysis of which yields a de-A-steroid of partial Formula (C) cyclization of which yields (I). The specific examples do not illustrate this route. Route 2 comprises hydrogenation of (II) to yield (A) as in route 1, treatment of (A) with an aqueous strong base to yield a de-A-steroid of partial Formula (E) acyl cleavage of which yields (C), cyclization of which as in route 1 yields (I). In the examples, the conversion of (A) to (I) is effected in a single procedural step using aq. KOH without isolation of (E) and (C). Route 3 comprises converting by usual methods the 5-carbonyl group of (I) into a group Z<SP>2</SP> which is di-(C 1-8  alkoxy)-methylene, phenylenedioxymethylene, a methylene group substituted by a divalent -ORO-, -ORS-, -SRS- or -ORNH- group (R being C 1-8  alkylene) or group of formula where R<SP>5</SP> is H, alkyl, alkoxyalkyl, phenylalkyl, tetrahydropyran-2-yl or acyl, and R<SP>6</SP> is H or C 1-8  aliphatic or alicyclic hydrocarbyl, hydrogenating the thus obtained compound to yield a de-A-steroid of partial Formula (B) treatment of which with a strong base yields successively compounds of partial Formulµ (F) and (G) wherein Z<SP>4</SP> is as Z<SP>2</SP> but not The group Z<SP>4</SP> is then converted to a carbonyl group to yield (C), cyclization of which as in route 1 yields (I). In the examples, the group Z<SP>2</SP> is ethylenedioxymethylene, the conversion of (B) to (G) is effected in a single procedural step using aq. KOH or NaOH without isolation of (F), and the conversion of (G) to (I) is effected in a single procedural step using HC1 without isolation of (C). Specified products are d- and dl-estr-4-ene-3, 17-dione, and dl - 13 - ethylgon - 4 - ene - 3,17- dione. The latter may be converted to norgestrel (see Specification 1,207,047). De-A-steroids of partial Formula (II) are prepared by selective hydrogenation of the corresponding 9,10-dehydro compounds (steroid numbering). The latter and also the antecedents thereof in Examples 7 and 8 are as described in Specification 1,298,212. Certain of the starting compounds and intermediates in Route 3 above comprise the subject-matter of Specifications 1,298,218 and 1,298,219.

Abstract: 1323788 Boring earth &c SOC NATIONALE DES PETROLES D'AQUITAINE 10 Dec 1971 [10 Dec 1970] 57486/71 Heading E1F [Also in Division F1] Signals generated at the bottom of a drilling well and representing measurements taken thereat are transmitted to the well head by periodically closing a needle valve 13 Fig. 1 in the path of the downcoming drilling fluid; the valve 13 being mechanically connected by its stem 57 to the upper end of a doubleacting hydraulic jack piston 56 supplied with working fluid by a pump 7 fast with the shaft 14 of a drilling liquid-operated turbine 16 and controlled by an electrically operated reversible servo-valve 50 responsive to the intensity of electric signals rotated to the measurement signals whereby the fluid flow to the jack is proportional to the signal intensity. The turbine 16 also drives an electric alternator 5 for supplying current to a unit 31 and thence to an encoder 59, an amplifier 60 and a sensor 33 responsive to the position of valve 13. In operation the sensor 33 supplies along a conductor 28 an electrical signal representing the position of valve 13 to the amplifier 40 to which is also supplied through a conductor 59' a reference signal from coder 59 rotated to the observed well measurements. The difference between signals at 28, 59' are transmitted by amplifier 60 along a conductor 58 to servo-valve 50 which results in movement of piston 56 in a direction tending to reduce said difference between signals at 28, 59'. In a modification the signal representing the position of valve 13 is responsive to the fluid pressure drop across the valve.

Abstract: 1479449 Automatic control CLARKE CHAPMAN Ltd 12 Feb 1975 [22 Dec 1973] 59718/73 Heading G3R An electric supply is controlled by deriving timing signals from a polyphase input, producing pulses at a rate determined by differences between actual and demanded voltage or current values, the pulses driving counters during periods defined by the timing signals, and using the outputs of the counters to control rectifiers by way of logic elements. As shown in Fig. 1, a three-phase supply is connected to input terminals 10, 12, 14. Each phase line contains a filter circuit 30 shifting the phase by 90 degrees, and a zero detection circuit 32, connected through NOR gates NO1-NO9 to reset terminals of six binary counters CO1-CO6. The counters are driven through NOR gates NO13- NO18 by pulses from a voltage controlled oscillator circuit 80, the frequency of which is determined by the relative magnitudes of a feedback voltage and a reference voltage on terminals 18, 16 respectively. The counter outputs are connected through NAND gates NA1-NA6 and amplifiers 50-60 to terminals 66 which supply gate signals to an array of SCR's, thereby regulating the quantity represented by the feedback at terminal 18. In one application, Fig. 3 (not shown), the supply is used to provide welding current over a series transistor current regulator circuit. An array of SCR's is connected in the input to the regulator circuit and controlled by a circuit as shown in Fig. 1 responsive to the voltage across the series regulator. Another arrangement, Fig. 4 (not shown), uses the circuit of Fig. 1 to control the speed and armature current of an A.C. or D.C. motor. The motor speed is measured by a tachogenerator producing a voltage or current representing the speed.

Title: Seals
IPC: B29C48/00
Filed: 1978-10-12
Abstract: A sealing head 2 for a pressurized treatment tube 1, such as a vulcanizing tube, for a cable 3 or similar elongated product comprises a housing 4 for fastening to the tube 1 and containing two flexible seals 6, 7 mounted in tandem in the direction of movement of the cable through central openings 8 in said seals. The housing defines chambers 10, 11 surrounding the seals 6, 7 and connected separately to a pressure medium source 17 whereby the openings 8 are adjustable in size by adjusting independently the pressures in the chambers and hence varying the radial compression force F. Thus the head 2 seals both against the pull rope for the cable and the coated cable so that the treatment tube may be pressurized at the very beginning of the treatment of the cable. An annular space 18 between the seals is adjustably connected to a second pressure medium supply, e.g. the interior of the treatment tube to provide a further seal. <IMAGE>

Title: Signal analysis, processing and correlation
IPC: G06E3/00
Filed: 1979-01-10
Abstract: Signals are received and correlated with stored representations. If a new signal is received it is stretched in time by a processor and then stored. The processor includes ultrasonic light modulators C1, C2, light source LS, L1, L2, S1 lenses L3 to L7, and bandpass filters S2, S3 to produce at photodetectors Dd-Da spatial distributions of light which are a function of an impulse fed to modulator C2 and the new signal fed to modulator C1. By virtue of the lenses L4 and L6, the distributions move relatively to one another at a predetermined speed giving rise to the time expansion. The photodetectors produce electrical signals, representing the correlation of the impulse and the new signal, the electrical signals being time expanded representations of the new signal. Once a signal has been correlated it is analysed. <IMAGE>
