Title: A directional discharge-nozzle device
Inventor: ERNST GUNTHER
IPC: B64C29/00
Filed: 1957-11-28
Abstract: 823,658. Deflecting propulsion jet on aircraft. SOC. NATIONALE D'ELUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Nov. 28, 1957 [Dec. 6, 1956], No. 37155/57. Class 4. Means for deflecting a propulsion jet on aircraft comprises a plurality of circumferential obstacles which may be moved within the jet pipe and blowing nozzles which exhaust round the inner periphery of a divergent extension of the jet pipe, the operation of a blowing nozzle being associated with the retraction of an adjacent aligned obstacle to facilitate adherence of the deflected jet round the surface of the divergent extension. The jet pipe 1 is slotted circumferentially at 3 for four abstacles 4 each mounted on an arm 5 pivoted at 6 on the jet pipe and connected by a rod 8 to a pilot's control member (not shown). The jet pipe carries a divergent extension 2 formed at its throat with four slots 10 each in axial alignment with an obstacle 4 and each supplied with compressed air by a pipe 11 having an operative connection 13 with the appropriate rod 8. To deflect the jet, one or more obstacles 4, as indicated in the upper part of the Figure, are moved into the jet stream with consequent closing of the corresponding valve(s) 12. Since the valve 12 associated with the withdrawn obstacle is open (lower part of the Figure) a gaseous jet will flow along the adjacent part of the surface of the divergent extension 2 to ensure the adherence of the deflected jet, indicated by dotted-line 15. The valves 12 may be operated independently of the obstacles 4 in order that all obstacles may be moved within the jet pipe to vary the cross-sectional area of the jet. In a further embodiment (not shown) the arms 5 are tubular and terminate in hollow, slotted obstacles so that sheet-jets of compressed air may supplement the deflecting effect of the obstacles.

Abstract: 367,491. Switchgear structures; oil switches. COATES, W. A., 165, Hale Road, Hale, Cheshire. Dec. 11, 1930, No. 37432. [Class 38 (v).] Switches, actuating.-Oil switches in which the movable part 4 is lowered from a fixed hood or shroud 3 to remove contacts 11 from contacts 1 for isolating purposes, have their movable bridging-member 7 operated rectilinearly by means of a rotatable shaft 9 carrying a lever 14. The ends of the lever 14 co-operate with projections 18 on a lever 17 movable with a pulley 16, which is connected by means of a cable or chain 28 with a hand-operated pulley 27 at the base of the structure. When, therefore, the switch is lowered for isolation purposes, the levers 17, 14 cannot co-operate to actuate the switch from the pulley 27, and as the pulley 16 is at all times fixed, the member 28 never gets slack.

Title: Purification of polyether polyols
IPC: C08G65/30
Filed: 1964-09-21
Abstract: Alkylene oxide polyether polyols are purified by adding formic acid to precipitate alkaline materials and removing the precipitate.  The formic acid is preferably added in sufficient quantity to reduce the pH to the range of 2.0-7.0.  The formic acid may be used in a gaseous state, as an aqueous solution, or as an anhydrous liquid.  Unreacted alkylene oxide may be first removed, before the addition of the formic acid, by stripping with an inert gas, e.g. N2 or CO2.  Excess formic acid may also be stripped with an inert gas, e.g. N2 or CO2 or vacuum stripped.  The precipitate may be agglomerated by the addition of a coagulating agent, e.g. CaCO3, and separated by filtration. The polyether polyols are reacted with tolylene diisocyanate to give polyurethanes.

Abstract: 1347640 Video tape recording COLUMBIA BROADCASTING SYSTEM Inc 18 Aug 1972 [19 Aug 1971] 38678/72 Heading H4F In a colour video tape recorder having a replay circuit the replayed video signal, at the output of demodulator 48, is synchronized with the studio sync pulses and colour subcarrier signal in two respective stages, the line sync pulses being extracted at 50 and compared in phase at 52 with studio sync pulses H, after they have been phase shifted at 62, 67 and 54 by a controlled amount, and the resultant comparison causing a control signal for variable delay line 13, and the thus coarsely corrected video signal is then passed through a further variable delay line 18 controlled by a phase comparison at 19 of the colour burst from stripper 56 with the studio subcarrier as phase shifted at 58 by a controlled amount. The corrected video at the output of processing amplifier 60 thus has its line sync pulses and subcarrier phased with the studio signal as desired. Due however to the frequency relationship between the subcarrier line rate, the phase of the subcarrier switches, relative to the line sync pulses, through 180 degrees on alternate frames (see Fig. 1, not shown). The subcarrier in the corrected video can thus have either of two phases relative to the line sync pulses, depending on which frame was used for the initial synchronizing in delay line 18. When a different program is spliced on to tape 24 the change from the last field of the first program to the first field of the second program, may be accompanied by a detection that the relative subcarrier phases in the two fields differ by 180 degrees. This will result in a sudden line or sideways rephasing shift in the displayed picture. To overcome this the present system envisages a clocking-up mode in which the detection of the 180 degree change in relative phase brings about the rapid movement of the tape through a distance such that the next frame is replayed instead of the previous one bearing the out of phase subcarrier. In the locking-up mode the adjustable phase shifters 54, 58, 62, 64 are by-passed or fed with a reference control signal to bring about a standard condition for the phases of the reference or studio sync and subcarrier signals. A voltage sensor 70 detects when the phase comparison at 19 indicates that the studio subcarrier is more than 90 degrees out of phase with the colour burst and sends a signal, via 106 to a capstan servo rotor 36/38, whereby the capstan 32 moves the tape through one frame.
