[Also in Division F2] Apparatus for winding up on paying out cable 12 to/from a cable tank 11 in a ship 10 comprises a driven winding drum 15, a hauling off sheave 13, adjustable first coupling means responsive to rotation of the drum in one direction when winding in cable to drive the sheave 13 and second coupling means responsive to rotation of the drum in the other direction when paying out cable to couple the sheave 13 to an adjustable braking means, the first coupling braking means being adjustable to vary the tension of the cable passing between the drum 15 and the sheave 13. The drum 15 driven by means 20 drives a sprag clutch 37 via the gear train and slip clutch 35 shown in Fig. 2. The sprag clutch 37, during winding in of cable, takes the drive through from the slip clutch 35 to the sheave 13 via gearing 38, 39. Any excessive tension in the cable between the drum 15 and sheave 13 is relieved by the clutch 35 slipping, the point at which slipping occurs being adjustable. During paying out of the cable the drum 15 is reversed and the sprag clutch 37 is disengaged and the sheave 13 is only driven by the cable passing over it. Rotation of the sheave in this direction causes a sprag clutch 41 to engage and couple the sheave to an adjustable friction brake 43 for further tension regulation. Specifications 990,811 and 990,812 are referred to.

Title: Yohimb-17-ene derivatives
IPC: C07D459/00
Filed: 1962-08-21
Abstract: The invention comprises yohimbene derivatives of the formula <FORM:0982197/C2/1> wherein Z is a formyl carboxy or lower carbalkoxy group and pharmaceutically acceptable acid-addition salts thereof and their preparation by splitting off a molecule of H2O from a 17a -hydroxy-yohimbane having at the 18-position a nitrile, carboxylic acid or ester group, by treatment with an alkali-metal hydroxide, if desired, when a yohimb-17-ene-18-carbonitrile is formed, hydrolysing to give yohimb-17-ene-18-carboxylic acid and if desired, converting the acid to the ester and converting the product to its addition salt.  The splitting of H2O from the 17a -hydroxy compound may also be effected by converting to the corresponding O-sulphate, O-mesylate, O-tosylate, O-phosphorodichloridate or O-chlorosulphite and eliminating the esterifying acid by treatment with a base. 17a  - Hydroxy - yohimban - 18a  - carbonitrile and 17b  - hydroxy - yohimban - 18 - a  - carbonitrile are made by condensing yohimbane-17-one with ethyl formate in the presence of sodium methoxide to give 18-hydroxymethyleneyohimbane-17-one hemihydrate and either reacting with hydroxylamine to give a mixture of yohimbano - [17,18 - c] - isoxazole and yohimbano-[18,17-d]-isoxazole hydrochlorides, followed by decomposition by sodium ethoxide to 17-oxoyohimbane - 18a  - carbonitrile or, reacting the 18 - hydroxymethyleneyohimban - 17 - one with O,N - bis - (trifluoroacetyl)hydroxylamine to give the 18a -carbonitrile and reducing the product obtained by either method, e.g. with sodium borohydride, to the 17-hydroxy-derivative, which is separated into the 17a - and 17b -isomers by chromatography.  Methyl 17a  - hydroxyyohimban - 18a  - carboxylate-O-tosylate is made by treating methyl 17a -hydroxyyohimban - 18a  - carboxylate with p-toluenesulphonyl chloride and is converted to methyl yohimb-17-ene-18-carboxylate by heating in 2,4,6-collidine.  18 - Isobutoxymethyleneyohimban - 17 - one is made by etherifying 1-hydroxymethylene-hohimban-17-one with isobutyl alcohol and is converted to yohimb-17-ene-18-carboxaldehyde by reducing with lithium aluminium hydride and treating with aqueous mineral acid.

Abstract: 974,236. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 15, 1963 [Aug. 21, 1962], No. 32072/62. Heading H4K.  A PBX final selector FSR of the uniselector type having an associated common control circuit CCC with tens and units switches DA1 DB1 is further controlled by a marker CMC which is common to a number of such control circuits and which, when the dialled number represents a PBX group, marks all the lines of that group, but, when the number is that of an individual line or a night service line of a PBX group, marks only that line. As shown, when a PBX group is called, the marking applied to the first line such as MW/43 is extended over rectifiers such as MR2, MR3 to all the other lines of the group. If, however, a night service line such as MW/70, MW/98 is called the rectifiers prevent the extension of the marking. In another arrangement, Figs. 2a, 2b, 2c (not shown), the marking on the first line energizes a relay which extends the marking. The marker CMC is seized, provided it is idle, by rest relay MT which operates by condenser-discharge under the control of a pulsing relay FT (not shown).

Abstract: 1,044,197. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. Aug. 6, 1964 [Aug. 7, 1963; Jan. 31, 1964], No. 32118/64. Heading H3B. The output of a crystal laser is controlled by providing an opaque screen in the resonant cavity containing the crystal and destroying the screen at the moment when maximum population inversion is achieved. Ruby laser 12 is pumped by xenon flash-tube 13 energized from source 16. Energization of the flash-tube triggers a monostable multivibrator 21, which after a predetermined time generates a pulse to trigger a silicon-controlled rectifier 23. This causes a large current to flow through a wire or a wire grid 14 sufficient to vaporize the wire. Lenses 9, 10 focus the laser beam to a small spot in the plane of screen 14 and recollimate the beam, respectively, so that the screen prior to destruction, prevents resonance in cavity 11, 15. In Fig. 4 a rotary commutator 35 first completes the flash tube circuit then allows capacitor 33 to discharge through wire or grid 14. An additional lens 31 and wire or grid 32 are provided outside the cavity, the second screen being vaporized simultaneously with the first. In another embodiment, an opaque layer on a transparent support is destroyed by the heat generated by a beam from an auxiliary laser. The second laser may be of lower power than the main laser, and may be controlled by a moving mirror or a Kerr cell. The screen may be of metallic or organic paint on a glass substrate, or may be a self-supporting metallic or organic plate. In this embodiment the main laser has a right-angled prism at one end instead of a plane mirror.
