Title: Catalyst compositions
IPC: B01J31/26
Filed: 1959-06-17
Abstract: A catalyst composition comprises anhydrous AlCl3 dissolved in an ester of a C1-6 aliphatic alcohol with a C1-6 fatty acid and optionally also anhydrous ZnCl2, the latter constituting about 10 wt. per cent of the AlCl3. Ethyl acetate is the preferred ester, but others specified methyl and n-propyl acetate, n-butyl formate and ethyl propionate, as well as (less preferably) secondary alcohol esters such as iso-propyl and sec.-butyl acetate.  Other ingredients which may be present are FeCl3, SnCl4, TiCl4, CdCl2, and HgCl2.  The catalyst is used in the reaction of ketene and formaldehyde to give b -propiolactone.ALSO:Betapropiolactone is produced from ketene and formaldehyde by introducing into the reaction zone a catalyst in the form of a solution prepared by dissolving anhydrous AlCl3 in an ester of a C1-6 aliphatic alcohol with a C1-6 fatty acid while maintaining the temperature low enough to avoid destruction of the AlCl3 by the ester.  The catalyst solutions, which may contain additionally e.g. ZnCl2, FeCl3, SnCl4, TiCl4, CdCl2 and HgCl2 are stated to be of use in respect of reactions generally using as catalyst dissolved AlCl3, and in particular for liquid phase production of lactones from ketene and aldehydes.

H. ; 402, Chilton Street, Elizabeth, New Jersey, U.S.A.) July 18, 1934, No. 20987. Convention date, May 10. [Class 38 (iv)] [See also Groups XXXVII and XL] In a vehicle - lighting system, parking-lights are switched on automatically, when daylight illumination falls below a certain value, by a photocell of the current generating type operating a switch associated with a relay. The photocell terminals are connected to the coil 3, Fig. 1, pivotally mounted between the ends of a permanent magnet 2 and carrying double contact arms 4 which engage small permanent magnets or contacts 6 when the current through the coil is insufficient to hold them clear. This current flow is not sufficient to overcome the attraction of the magnets 6 once contact has been made. The pin 8 carried by an arm 7 operated by hand is provided for disengagement. The connections between the relay R, the photocell C and the vehicle lighting system are shown in Fig. 4. The lighting switch carries three arms 11 which supply the headlamps H and the tail lamp T from the battery 13 through contacts 14, 16, 18 when turned in an anticlockwise direction. Adjustment in a clockwise direction energizes the parking lights P through contacts 14, 17. When the switch arms 11 are in the neutral position shown, and the daylight illumination falls below a certain value, the arms 4 engage magnetic contact 6 and the parking lights P and tail lamps T are then illuminated from the contacts 14, the lights T being supplied through the leads 21, 22 and the contacts 6, and the lights P from the lead 21 contact 6, leads 23, 20 and contact 17.

Title: Remotely controlled recording system
IPC: H04M1/652
Filed: 1951-09-06
Abstract: 698,376. Centralized dictation systems. EDISON, Inc., T. A. Sept. 6, 1951 [Jan. 6, 1951], No. 21057/51. Class 40 (iv). The recording apparatus is provided with means for indicating when a dictator finishes using the system after having recorded beyond a predetermined point on the record. An attendant is thereby warned to change the record when insufficient recording space is left to accommodate the average length of dictation, and the apparatus cannot be re-engaged for further dictation until the record has been changed. As shown, a subscriber at a dictation station 11 by lifting his handset 54 from its cradle switch 60 completes a circuit for a relay 68, which starts the recorder motor M and lights a busy signal lamp L at each dictation station. Depression of a switch 74 shunts out a resistance 72, and the resultant increase in current brings up a second relay 67 which energizes the start coil 90 of an electromagnetic clutch 91 to start the record turntable 17 revolving. Dictation can now be recorded by means of recording-head 31, and the dictator may make correction marks or the like by momentarily depressing his cradle switch 60 to release relay 68, thereby briefly energizing a marking solenoid 95, relay 67 being slow-releasing. To play back the record, the dictator depresses a switch 75 to shunt out a resistance 73 as well as 72. The further increase in current brings up a third relay 69 which switches the circuits to provide for reproduction from a reproducing head 32. When the recording head travels beyond a predetermined point, a projection 98 on its carriage closes a switch 97, and the release of relay 68 when the dictator subsequently hangs up removes a shunt from a buzzer 100 which warns an attendant to change the record, the busy lamps L remaining lit. The attendant closes a switch 102 to shunt out the buzzer 100, the clutch-control relay 67, and filter coils 66, so that a warning hum is fed into the speech circuit. A neon lamp 103 indicates to the attendant that the switch 102 is closed. To change the record, the attendant releases a clamp 33, causing a warning lamp 104 to flash. If the recording head approaches the end of the record, switches operated by the projection 98 control warning signals to the dictator and to the attendant and finally release the clutch to stop the turntable 17.
