Abstract: The invention comprises 3,4; 15,151 - bis-dehydro - b  - carotene and 15,151 - monocis-3,4 - dehydro - b  - carotene and the preparation thereof by condensing acetylene through one of its reactive hydrogen atoms with 8-[21,61,61-trimethyl - cyclohexadiene - 11,31 - yl - 11] - 2,6-dimethyl - octatriene - 2,4,6 - ol - 1 and through the other of its reactive hydrogen atoms with 8-[21,61,61 - trimethyl - cyclohexen - 11 - yl - 11]-2,6 - dimethyl - octatriene - 2,4,6 - al - 1 by means of metal-organic reactions subjecting the 1 - [21,61,61 - trimethyl - cyclohexadiene - 11,31-yl - 11] - 18 - [21,61,61 - trimethyl - cyclohexen-11 - yl - 11] - 3,7,12,16 - tetramethyl - 8,11 - dihydroxy - octadecahexaene - 2,4,6,12,14,16 - ine-9 thereby produced to bilateral allyl rearrangement and dehydration and, if desired, partially hydrogenating the 3,4; 15, 151-bisdehydro-b -carotene so obtained at the triple bond therein to give 15,151-monocis-3,4-dehydro-b -carotene.  The condensation may be effected by first reacting the aldehyde initial material with an alkali-metal acetylide or an alkaline earth acetylide in liquid ammonia and reacting the condensation product so obtained with 8-[21,61,61 - trimethyl - cyclohexen - 11 - yl - 11]-2,6 - dimethyl - octatriene - 2,4,6 - al - 1 or 8-[21,61,61 - trimethol - cyclohexadiene - 11,31-yl - 11] - 2,6 - dimethyl octatriene - 2,4,6 - al-1 in a metal organic reaction, e.g. by means of an alkyl magnesium halide or lithium phenyl.  The bilateral allyl rearrangement and dehydration of the diol product of the first stage may be effected by heating with phosphorus oxychloride or pyridine hydrochloride in the presence of an excess of pyridine and in an inert solvent, or by heating under reflux with a strong organic acid, e.g. p-toluene sulphonic acid in the presence of toluene, or by reacting with hydrogen halide and treating the dihalo compound so formed with water or a basic compound.  The hydrogenation may be effected in the presence of a hydrogenation catalyst.  The 15,151-monocis 3,4 - dehydro - b  - carotene may be isomerized to the corresponding all-trans by treatment with iodine, by irradiation or by heating. Specification 786,003 is referred to.

A photo-electric copying system for controlling gas-cutting machines and machine tools comprises a non-rotatable photo-head, with a circular optical scanning light beam intersecting a drawn line, having a sensing element connected in cascade to a unidirectional limiting amplifier, a differentiating circuit and a phase synchronized time selector whereby a pulse from the differentiating circuit, corresponding to the forward point at which the light beam crosses the line, is selected and shaped to an approximately sinusoidal voltage and used to control the machine drive motors. As shown, the circular light scan of a non- rotatable photo-head 1 intersects a drawing line so that phase-modulated photo-current pulses are developed and fed through a unidirectional limiting amplifier 3 to a differentiating circuit 4. The leading edge of a pulse from the circuit 4 corresponds to the maximum of a photo-current pulse and is fed to a time selector 5 which selects the pulses corresponding to the leading point of the scan. The time selector incorporates a coincidence circuit 6, comprising a double-triode with common anode load, connected to the circuit 4 and a phase shifter 9 whereby a scan dependent pulse is selected which is fed to a multi-vibrator 7 generating a rectangular voltage which is shaped to a sinusoidal voltage in a valve-filter 8. The valve filter energizes, through a transformer, not shown, to which is coupled the phase shifter 9, phase detectors 10, formed by Scott-connected transformers deriving quadrature signals Vx, Vy which are fed to a positioning system for a machine and a copying table. The machine is positioned Fig. 2, (not shown), by D. C. motors controlled by amplidynes, feedback being applied through tachogenerator. A copying table is positioned in correspondence by selsyns.

A blind riveting tool adapted to drill a hole in at least one of the sheets to be joined comprises a sleeve 67 coaxially connected to a motor-driven drive shaft 65 for rotation therewith and axial sliding relative thereto by a fluid pressure piston and cylinder 91, 92 via means 88 and a mandrel gripping device 76 connected to the sleeve 67 so as to be rotated thereby and moved axially therewith. One end of the sleeve 67 is connected to the drive shaft 65 by a keyway connection 69, 70, 71 and the other end is connected to a shaft 72 carrying at its forward end collet fingers 76 positioned in a rotatably and slidably mounted sleeve 77. The mandrel 85 having a drill point at its one end (Fig. 4A, not shown), is engaged in a bore in the shaft 72 and is gripped by collet fingers 76 spring-loaded by a spring 79. When a control valve 101 is operated, air is admitted from a chamber 100 to operate an air motor 64, which rotates the drive shaft 65. Simultaneously, the sleeve 67, shaft 72 and mandrel 85 are rotated, the latter drilling a hole in a sheet. After drilling, a further valve (116), (Fig. 2, not shown) is operated to cause fluid under pressure to move the piston 92 against the action of a spring 98. An arm 88 is thereby pivoted causing the sleeve 67 to be moved to the left over the shaft 65 and the mandrel 85 to set the rivet.
