Filed: 1974-11-06
Abstract: 1484624 Alkenylation of alkylbenzenes TEIJIN Ltd 6 Nov 1974 48088/74 Heading C5E In a process for preparing alkenylbenzenes in which 1,3-butadiene is reacted with an alkyl benzene in the presence of an alkali metal catalyst, fresh feed alkylbenzene is contacted before being fed to the reaction zone, with the reaction mixture, or with a part thereof remaining after separating at least one of the catalyst, unreacted alkylbenzene or alkenylbenzene product, or with a catalyst-containing composition separated from the reaction mixture. This method obviates the necessity for removing water and molecular oxygen from the feed, which would otherwise impede the reaction. As shown in the Fig., the alkylbenzene may be fed, via line n, directly into the reaction product stream a leaving the reaction zone 1. The resulting mixture is passed to a catalyst separator 2 and then to a separator 3 where both the added alkylbenzene and the unreacted alkyl. benzene are distilled from the mixture and returned to the reaction zone (line g). Alternatively, the alkyl-benzene may be fed into line e which carries the separated catalyst and a part of the reaction product. In this case, the pretreated alkylbenzene may be separated from the catalyst at 2<SP>1</SP> and fed to the reaction zone or fed directly to the reaction zone without separation. The catalyst is preferably a Na/K alloy and suitable alkylbenzene feeds are toluene, xylene, ethylbenzene, trimethylbenzene and tetramethylbenzene. Examples describe the production of 5-tolyl pentene-2 (o-, m- and pisomers) and 5-phenyl hexene-2.

The plug seals-off the tubing when pin 20 is sheared, this shearing being effected by extreme fluid pressure down the well, or by the application to the push rod of a tractive force, or by the dropping of a weight. A large tractive force applied to the push rod 18 shears pin 21 to permit the push rod to be removed.

In Fig. 3, uranium 92isvaporised in an electron beam furnace (electron gun 98, cooled crucible 86) and the vapour is subjected to laser irradiation of energy appropriate to the desired selective excitation and ionisation. The laser irradiation system is of a conventional form used in selective photo-ionization isotope separation and is described with reference to Fig. 2 (not shown). A magnetic field 104 is continuously applied to the vapour region and pulses of voltage are applied between alternately connected radial plate electrodes 108, 112. The voltage pulses are applied in synchronism with the laser pulses and are of short duration to avoid collecting undesired ions resulting from charge exchange reactions. Fig. 4 shows in detail the particle paths, the electrons 122 circulating in orbits around electrodes 112 while the desired ions 120 are attracted to the electrode 112 where they are collected.

A flight simulator comprises a television camera 2 moved in response to control signals to produce for at least part of the simulated flight an electrical analogue of a simulated view from an aircraft, said view having a first surface 4 simulating the earth's surface, e.g. a seascape and a second surface, dome 3 simulating the sky, the camera 2 and the dome 3 being movable together in at least the direction Z corresponding to altitude and the camera being movable in at least one other direction X. As shown, camera 2 may be moved along axis Z which represents altitude by carriage 10 and moved along axis X by carriage 9. The camera may be rotated about an axis 13 parallel with axis Z as shown by the arrow. Model 1 supported on carriage 6 may move parallel to the axis Y. The rotation of the camera about axis 13 causes rotation of the viewing axis 15 and simulates alterations of heading of the aircraft. At 16, the extremity of the camera, is placed a 45 degrees mirror constituted by a rotatable isosceles rectangular prism which when rotated simulates pitch of the aircraft. Between position 16 and the target electrode of the camera is placed a Wollaston prism which is adapted to rotate about the Z-axis and simulates the roll of the aircraft. Supported by the camera is an horizon system 21 one face 21a of which is frosted while face 21b is clear. When holder 22 leaves the vertical position face 21a covers up the object of the camera simulating during rotation of holder 22 the passage of the aircraft in a cloudy region. The horizon line defined by the intersection of celestial dome 3 and the sea scenery 4 is displaced according to the altitude function Z through link 24 attached to dome 3 and a slider 25 linked to part 10.

In an I.C. engine fuel injection control system, when the engine speed reaches a pre-set value injection occurs simultaneously in more cylinders than when the speed is below said value. As shown, when the engine speed reaches said value a switching circuit 49 causes switches 26, 35 and 38 to change over and thereby cause the two groups of injection valves 44, 46 to be actuated simultaneously whereas; below said value they operate alternately. The switching circuit Fig. 2 (not shown), includes a threshold circuit and a relay for the switches 26, 35 and 38, or alternatively the switches 26, 35 and 38 may be electronic (i.e. transistors). It may be arranged that, when the engine speed falls again, two group injection occurs at a lower speed value than said pre-set value. The injection pulses are computed by a circuit 27 and have a width dependent upon engine speed, intake manifold pressure and engine temperature.

Title: Improvements relating to stereophonic radio receivers
Inventor: GEHRKE HERBERT

Filed: 1965-11-25
Abstract: 1,059,007. Stereophonic radio receivers; transistor relay circuits. TELEFUNKEN PATENTVERWERTUNGS-G.m.b.H. Nov. 25, 1965, No. 50130/65. Headings H3T and H4L. In a stereophonic radio receiver, a relay responsive to the transmitted subcarrier when present switches the receiver from mono to stereo reception, and an automatic switch device which is responsive to the temporary closing of a key when the receiver is conditioned for stereo reception conditions the receiver for mono reception, the switch device being held by the rectified subcarrier oscillations. This enables the receiver to be switched over to mono reception when a stereophonic signal is being received under adverse noise conditions, but automatically returns the receiver to its normal mode of operation on retuning. As shown in Fig. 2, when stereo signals are received negative half-cycles of the 38 kc./s. subcarrier cause transistor 9 to conduct and operate relay 6 to switch the receiver for stereo operation, a further contact 13 being closed to connect resistor 14 to reduce the time constant of circuit 10, 11. The reduction of the time constant ensures that a positive voltage does not build up and prevent switching in the event of a rapid change to a different stereo transmission. If the key 7 is pressed and released the positive biss from battery 8 causes relay 6 to be released and the receiver is conditioned for mono operation. Resistor 14 is disconnected and rectification of the subcarrier by the baseemitter circuit of the transistor maintains the transistor blocked. In a modification, Fig. 3 (not shown), the relay is connected in parallel instead of in series with the transistor 9 and is energized for mono reception. In an alternative arrangement, Fig. 1 (not shown), a second relay is used which overrides the stereo-mono relay when the mono-key is pressed and is held operated by the rectified subcarrier. In a further arrangement, Fig. 4 (not shown), the relay 6 is replaced by a trigger circuit and the relay contacts are replaced by diodes.
