Title: Ring laser
Inventor: MCCLURE ROBERT EDWIN
IPC: H01S3/083
Filed: 1967-11-21
Abstract: 1,203,628. Lasers. SPERRY RAND CORP. 21 Nov., 1967 [29 Nov., 1966], No. 52814/67. Heading H1C. In a ring laser rotation rate sensor in which plane polarized light beams from a gas laser source 1 are propagated in opposite directions in a closed loop optical cavity comprising mirrors 4, 5 and a Faraday cell 11, the frequency locking threshold is reduced by applying an alternating signal from an adjustable voltage source 13 to the Faraday cell so as to frequency modulate the two beams, and by simultaneously frequency modulating from the same signal source one of the two beams 18, 19 extracted from the optical cavity. The Faraday cell 11 forms part of a composite structure 6 comprising Brewster angle prisms 7, 8 and quarter wave plates 9, 10, the prisms producing the output beams 18, 19 by partial reflection and the quarter wave plates converting the plane polarized closed loop beams into circular polarization. The Faraday cell, when energized by current in coil 12, introduces an optical delay which is different for the two directions of closed loop propagation. The extracted beams are collimated by mirror 20 and beam splitter 22, and detected by photo detector 23, mirror 20 being variably positioned by energization of a piezo electric element 24 from A.C. source 13 and constituting the modulator for beam 18. The alternating signal has a frequency substantially higher, e.g. five times, than the minimum beat frequency obtainable from the laser in the absence of both modulators. The beat frequency output may be biased by using a D.C. source 16. In a modification only one of the two beams in the closed loop is internally modulated.

Title: A process for the polymerization or copolymerization of cyclic esters of hydrocarboxylic acids
IPC: C08G63/08
Filed: 1965-12-13
Abstract: Polyesters are made by polymerizing certain lactones in the presence of an organic sulphide, sulphoxide or sulphonium compound.  The lactones are those containing the group <FORM:1096899/C3/1> wherein R1, R2 and R3 are hydrogen atoms o substituted or unsubstituted hydrocarbon radicals, the ring of the lactone being closed between the terminal carbon atoms of the group by a direct bond, a chain of at least two carbon atoms or a carbonyloxy group.  The organic sulphides have the formula R4 (S)n R5 and the organic sulphoxides have the formula R4.SO.R5 where R4 and R5 are aliphatic, cycloaliphatic at aromatic hydrocarbon radicals which may be substituted (e.g. by halogen atoms, or hydroxyl, alkoxy, aryloxy or arylmercapto groups) and n is a whole number.  The organic sulphonium compounds are addition products of the above sulphides with organic halides. Polymerization may be effected by a bulk process or in solution (e.g. a hydrocarbon, a halogenated hydrocarbon, a nitrated hydrocarbon, an ether or cyclic ether, an ester or a nitrile). Copolymerizable monomers (e.g. ethylene oxide, epichlorhydrin, a glycidyl ether or ester or a lactam) may be included in the reaction mixture.  Examples describe the polymerization of (1)-(4) Alpha, alpha-dimethyl - beta - propiolactone which had been freed from water and other active hydrogen-containing material by distillation with toluene diisocyanate; (5) Glycolide; (6) Beta-propiolactone purified as in Ex. 1.

An electric controller for an electric actuator for a door latch comprises an electric circuit which is completed in accordance with a code. The door latch 12 is released by actuation of an electric solenoid in a latch housing 14 fitted into a recess in a wall. A control panel 18 is mounted on one side of the wall and has a plurality of press buttons 26 which are selected in accordance with a code i.e. DFL a card key is inserted in a slot 30 to operate a switch 28 in a circuit contained in a housing 36 mounted on the side of the. wall. The housing comprises eight sequence terminator switches 96 one of which is operated in accordance with the number of components of the code, in this case 4. A sequence switch with contact 98 is associated with each switch 96 and a relay 82 is associated with each sequence switch. The press buttons DFL and the card key switch 28 are connected by patch cards 70 to relays 82 and in sequence, 1, 2, 3 and 4 by connectors 84. A holding circuit for each relay 82 comprises switch contact 92 and time delay comprising heater element 88 of relay 82 and time delay switch 90 to limit the time for the completion of sequential operation of switches. All unconnected selector switches are connected to an alarm circuit. The holding circuit for the alarm has a time delay heater element 76 of relay 74 and time delay switch 78 for deactivating the alarm after a predetermined time. The alarm relay 74 has a switch contact 100 in circuit with the latch actuator for breaking the latch actuating circuit during operation of the alarm.
