Abstract: 1404025 Combinations of reflectors; flight simulators SINGER CO 5 Dec 1972 [13 Dec 1971] 56022/72 Heading G2J [Also in Division B7]  An optical system for shifting an optical axis and independently altering the length of the optical path comprises a silvered right-angle prism 37 and a corner cube prism 39, relatively oriented as shown in Fig. 5. Moving prism 39 vertically (as drawn) changes the path length. Moving it laterally in the plane of the figure shifts the output optical axis 53 vertically; moving it laterally at right angles to the plane of the figure shifts the axis 53 laterally. The system may be used in a flight simulator of camera model type to provide conjugate compensation, shifting of the optical axis, and roll of the image about the optical axis. Prism 37 is adjustably mounted on a diameter of a cylinder 61 which is rotatably mounted inside another cylinder 63 so as to provide for roll. Prism 39 is mounted on an X-Y table 75, to provide for lateral motion, at the end of a cylinder 67 slidable in a cylinder 65 disposed radially in cylinder 61, to provide for vertical motion. Three servomotors 73, 77, 77 provide the necessary three translatorial motions of prism 39 under the control of a computer, which also controls the degree of roll. The control circuit may be arranged to keep the position of the optical axis 53 constant during roll.

Filed: 1967-12-08
Abstract: 1,164,730. Bi-stable device. BENDIX CORP. 8 Dec., 1967 [30 Dec., 1966], No. 56030/67. Heading G4P. [Also in Division G3] A pure fluid vortex device operable as either a switch or a proportional amplifier is connected by valve 44 (Fig. 2) with a control source 42 of lower pressure than the main supply issuing into chamber 22 from radial port 30. Source 42 is preferably at atmospheric pressure, and when valve 44 is open, the fluid entering through port 30 flows in a vortex and the pressure available at outlet 34 corresponds with the degree of opening of valve 44. Closing this valve causes fluid from port 30 to flow radially to, and exert a higher pressure at, outlet 34. In the modification shown in Fig. 3 the main supply issues through a bell mouth 50 which produces wall attachment so that after valve 44 has been re-closed the vortex flow in chamber 22 is maintained until a second bleed valve 56 has been opened to destroy wall attachment and thereby effect radial flow to outlet 34. Thus the device can be used to produce pulses at outlet 34 in response to alternate operation of valves 44 and 56.

Abstract: 1,148,100. Separating conjugated diolefins. JAPANESE GEON CO. Ltd. 29 Dec., 1966 [30 Dec., 1965(2)], No. 58178/66. Heading C5E. A process for the separation of a conjugated diolefin from a C 4  or C 5  hydrocarbon mixture containing said conjugated diolefin and higher acetylenes (including allenically unsaturated hydrocarbons) comprises subjecting the hydrocarbon mixture to extractive distillation with a solvent consisting essentially of an N-alkyl substituted aliphatic acid amide of the formula RCONR 1 R 2 , wherein R and R 1  are each a hydrogen atom or a C 1 -C 3  alkyl radical and R 2  is a C 1 -C 3  alkyl radical, recovering the conjugated diolefin as a distillate and the higher acetylenes as an extract in the solvent, and subjecting the extract to stripping so as to recover the solvent as bottoms liquid and the acetylenes as overhead fraction. If the hydrocarbon mixture also contains hydrocarbons less soluble than the conjugated diolefins such as paraffins and mono-olefins, then a two stage extractive distillation process may be used to recover the pure conjugated diolefin, a mixture of the conjugated diolefin and higher acetylenes being obtained as an extract in the first stage and the less soluble hydrocarbons removed as top distillate, the extract then being extractively distilled in accordance with the invention to obtain the pure conjugated diolefin as distillate in the second stage. Examples describe the recovery of butadiene 1,3 and isoprene from C 4  and C 5  feedstocks respectively. The amide solvent is preferably dimethyl formamide, diethyl formamide or dimethyl acetamide and may be used in admixture with 0-01 - 30% by wt. of a polymerization inhibitor e.g. tertiary butyl catechol, sulphur, sodium nitrite, furfural benzaldehyde and aromatic nitro compounds.

Abstract: 595,606. Workmen's time-recorders. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 14, 1944, No. 17623. Convention date; Sept. 2, 1943. [Class 106 (iv)] In apparatus of the individual card type the card-holder is shifted laterally every 24 hours and subsequent records made within each 24 hour period are tabulated vertically below the first record by controlling the amount of insertion of the card by means of a feeling device co-operating with a hole punched in the card at the previous recording. After shifting a predetermined distance the cardholder is arranged to return to its initial position and a new initial stop lever is arranged to cause recording at a new level on the card. The lateral movement of the card-holder 1 is effected by a screw-threaded shaft 113 which is provided with a pinion 116 engaging a mutilated wheel 117 secured to a ratchet wheel 119 actuated by a pawl 121 on a lever 127 cooperating with a time-controlled cam. A spring on the shaft 113 is provided to return the card-holder to its initial position when a mutilated part 141 or 142 of the wheel 117 reaches the pinion 116. The vertical tabulation is effected by the hole-punching and holefinding means described in Specification 589,653. Upon the return of the card-holder to its initial position a new stop lever 101 is brought into action above the first stop lever 11 by the counter-clockwise motion of a lever 145 caused by a stud 144 thereon riding on to the high part of a cam 143 fixed to the wheel 117 the transfer of motion being through a lever 147 fixed to the same shaft 146 as the lever 145 having a slot co-operating with a stud 148 on the stop lever 101. Subsequently, the first insertion of a card during each 24 hour period will actuate the lever 101, thereby releasing the operating handle by causing a clockwise movement of the shaft 12 through a link 103 fixed thereto and pivoted to the lever 101. By introducing a second pair of stop levers 11 and 101 the mechanism can be arranged to operate, with cards appropriately printed, for a calendar month, in cycles of eight days, a final adjustment being required at the end of the month to complete the last cycle by means of a hand lever 151 bearing on the lever 127 and advancing the pinion 116 independently of the timecontrolled cam. To prevent tampering, the lever 151 is locked by a link 161 controlled by levers 163, 164 and is released by a key cooperating with the lever 164.
