Abstract: 1,170,871. Alkylating aromatic hydrocarbons. UNIVERSAL OIL PRODUCTS CO. 26 Feb., 1968 [2 March, 1967], No. 9123/68. Heading C5E. In a process for alkylating aromatic compounds with a molar deficiency of olefin-acting compound in a reaction zone in the presence of an unreactive vapour diluent, an improvement comprises passing the total effluent from the reaction zone into a rectified flash zone comprising a settling chamber for separation of liquid and vapour and a superposed zone for the rectification of the separated vapour, therein separating the effluent to provide a vapour phase comprising diluent and a portion of the unreacted aromatic compound and a liquid phase comprising alkylated aromatic compound and unreacted aromatic compound, separating the unreacted aromatic compound from the liquid and vapour phases and returning at least a portion of it to the reaction zone, and recovering the alkylated aromatic compound. The upflowing vapour in the rectified flash zone may be refluxed with unreacted aromatic compound, unreactive vapour diluent or a mixture thereof, or alkylated aromatic compound. The alkylation may be effected in the presence of an acid-acting catalyst, e.g. a calcined composite of hydrated phosphoric acid or a siliceous absorbent, or a complex of BF 3  with Al 2 O 3 . The aromatic hydrocarbon may be benzene, or alkylbenzene, or a multi-ring compound containing fused or unfused rings. The alkylating agent may be an olefin, cyclo-olefin, diolefin, acetylenic hydrocarbon, alcohol, ether, alkyl halide or ester. Preferred processes are the production of ethylbenzene by alkylating benzene with ethylene in the presence of ethane, and the production of cumene by alkylating benzene with propylene in the presence of propane.

Abstract: 1458614 Optical read-out device for a data carrier THOMSON-BRANDT 28 Feb 1974 [2 March 1973] 9210/74 Heading G1A In an optical read-out device for a record 10, Fig. 1, comprising a spiral track 6, 7, 8 consisting of raised portion and recessed portions 9 an elongated "light bar" or "spot" 11 is formed across the track 7 by means of a lens 2 and an apertured plate 1, and the diffraction pattern formed by the radiation passing through the record 10 is monitored by a central photo-detector 12 (for the zero order diffraction) and two side photo-detectors 13 and 14 (for the higher orders of diffraction). The outputs VG and VD of the two side photo-detectors are fed to an operational amplifier 17 to provide an error signal e(t) which will indicate if the "light bar" is centrally positioned across the track or not [within a given margin of variation Fig. 2 (not shown)]. The outputs of the two side detectors  are also fed so as to provide a mean value to an input of a further differential amplifier 16 which also receives the output VM of the photo-detector 12 and the further differential amplifier's output V(t) (Fig. 2) constitutes the read-out signal of the data contained in the record. In another arrangement Fig. 5 (not shown) the "light bar" is formed by a combination of divergent and convergent  cylindrical lenses.  In Fig. 4, the elongated "light bar" is formed with the aid of the non light-sensitive back surfaces of the side photo-detectors 13 and 14, as shown, and the radiation reflected off the record is detected with the aid of a semi reflector 27. The detectors 12, 13, 14 and their output signals are positioned and processed in a similar fashion to the Fig. 1 embodiment. Other ways of forming the "light bar" are briefly mentioned such as using a holographic lens or a Fresnel lens.
