Title: Process for aromatic alkylation and olefinic oligomerization
IPC: C07C1/00
Filed: 1968-03-01
Abstract: 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.

Filed: 1968-04-06
Abstract: A transit ticket 10 for use in an automatic fare collection system has positioning slots 12 along the centre line 14 and an encodable magnetic matrix 16. The magnetic matric comprises two columns 18, 20 of magnetic inserts 22 located symmetrically with respect to the line of slots 12, each column being used to register binary information. The ticket is made of a plastics core member having a number of holes punched on each side of the centreline 14, each hole then being filled with a magnetic insert 22. An opaque plastics film is heat and pressure sealed over the top and bottom of core member. The magnetic inserts are made of powdered magnetic material, e.g. alnico provided with a binder. The magnetic inserts are each encoded as a zero or a one by driving the magnetic inserts to saturation in one of the two possible polarities relative to the face of the ticket. Four extra columns of cylindrical inserts 42, 44, 46, 48 (Fig. 3, not shown), parallel to the line of slots 12 may be provided in the magnetic matrix for encoding the ticket for multiple trip use. The positioning slots 12 may be punched in the ticket on vending and the inserts 22 magnetized along their major axes in groups of eight, corresponding to ticket orientation, fare value, station of origin and time/date. For a multiple trip ticket (40), in addition inserts (50) are punched out in columns (42) and (44) leaving only those inserts (50) corresponding to the value to the individual trips purchased.

Title: Radio-Frequency Radiation Monitor
IPC: G01R29/08
Filed: 1968-06-07
Abstract: A circuit for producing a chirp note when an RF field is present comprises a coil L tuned by CI to the RF field, e.g. 200 MHz, (continuous or pulsed) the picked-up signal being rectified by DI to change C2. At a predetermined level depending on the setting of P the unijunction Q1 will fire and apply pulses to transistor Q2 at a frequency depending on the RF level. At each pulse capacitor C4 changes and turns on Q3, the time constant of C4 and R2 determining the duration of the chirp. When Q3 conducts, capacitor C5 alternately changes through R3 and discharges through a second unijunction Q4 to produce a chirp A. F. signal at a frequency depending on R3. This signal is amplified and fed to a Piezo-electric or other loudspeaker S. Diodes D2 and D3 prevent the associated transistors from being cut off by large signals. The circuit may be used as a personnel monitor for dangerous R. F. fields or for locating leaks in waveguides or cooling lines.

Title: Process for making acrylamide
IPC: B01J23/00
Filed: 1974-04-26
Abstract: A process for catalytically hydrolyzing acrylonitrile to acrylamide. A reactor is filled with a desired quantity of water and a copper catalyst is suspended therein with agitation.

Thereafter, agitation is stopped, the catalyst falls to the bottom of the reactor, and an acrylamide solution is decanted off the top of the reactor. The sequence of steps is repeatable using the same copper catalyst.

Patent ES-461493-A1 (ES)
Title: flying toy
IPC: A63H27/127
Filed: 1977-08-08
Abstract: A flying toy of the rotating blade type, comprises a bladed spinner which is twirled by a shaft that is rotated by pulling a string that is wound about the shaft. Pivoted hooks are urged by the centrifugal force of an extended portion thereof, radially inwardly to retain the spinner for rotation with the shaft so long as the shaft is rotating. But when the string is fully unwound and the shaft stops rotating, then the inertia of those same weighted portions swings the hooks radially outwardly to release the spinner, which is thus launched. A flared bell on the toy receives the spinner when it falls again and the string is wound back up on the shaft by an elastic that rotates the shaft in a direction opposite the unwinding direction.
