Abstract: 772,023. Clocks. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Aug. 13, 1954 [May 10, 1954], No. 23649/54. Class 139. Apparatus for transmitting time signals comprises means for periodically transmitting a signal comprising a plurality of modulated impulses corresponding in number to the time expressed in units of time elapsed since a predetermined instant of time. The transmitter comprises a master clock having a seconds hand 1 carrying contacts 2, 3 which co-operate with stationary contacts 2', 3' and a minute hand 12 carrying a contact 13 which cooperates with a contact 13' carried by an arm 16 periodically rotated at the speed of one revolution per second by a motor 7. The contacts 2, 2' are in the circuit of a motor 7. The contacts 3, 3' are in the circuit of switching means 10 which controls the operation of an oscillator 11. The contacts 13, 13' are also in circuit with the switching means 10. The arm 16 has a contact 20 which moves over a series of contacts on a disc 21 connected to the switch means 10. Secured to the arm 16 is a cam 18 which controls contacts 19, 19' connected in parallel with contacts 2, 2'. A plate 22 is rotated through fifteen degrees every hour and carries two contacts 23, 23' controlled by a cam 24 arranged to be rotated through fifteen degrees for every revolution of the arm 16. The contact 23 is connected to a relay 25 which controls a switch 26 in parallel with the contacts 2, 2' and 19, 19' while the contact 23' is connected to the normally open contact 27 of the relay 4. The arrangement is such that every minute when the contacts 2, 2' are closed the motor 7 rotates the arm 16 over the contacts on disc 21 so that the oscillator 11 transmits a series of impulses modulated at 1000 cycles per second and corresponding in number to the time expressed in minutes from a predetermined zero time. A heart-shaped cam 28 - which co-operates with a plunger 29 controlled by an electromagnet 30 ensures the return of the cam 24 to the initial position when the motor 7 stops. The transmitted signal may be received by apparatus including magnetictape recording means or by apparatus including clock hands carrying lamps and moving over a fluorescent screen. If desired two separate series of impulses one representing the " hours " and the other the " minutes " may be transmitted.

Traction motors are supplied from high-tension line 11 through circuitbreakers 13, a motor-generator set M, G supplying the low-tension circuits on the vehicle, and the motor M being energized from the line 11. If the line voltage falls to a low value, motor M acts as a generator to reverse the current through coil 15se of a protective relay, so that this coil opposes coil 15p which is connected across the lowtension circuit. Contacts 15d open to de-energize the line breaker operating coils 13a whereby the traction motors are disconnected from the line 11. The relay will also, by its contacts 15c, deenergize relay 18 so as to short-circuit economy resistor 17. In other arrangements, the winding 15se detects the voltage drop across a resistor or field coil in the motor circuit. The circuit to a master controller may be completed through contacts 15d or an additional set of contacts on relay 18.

Patent GB-987433-A (GB)
Title: Process for the manufacture of tetracyclic compounds
IPC: C07D317/72
Filed: 1961-07-03
Abstract: The invention comprises compounds of the formula <FORM:0987433/C2/1> in which R represents a hydrogen atom or a methyl group, R1 represents a hydrogen atom, an alkyl group containing 1 to 4 carbon atoms or a carboxylic acyl group and R2 represents a hydrogen atom or halogen atom.  The novel tetracyclic compounds are made by reacting a compound of the formula <FORM:0987433/C2/2> in which the grouping -O-alkylene-O-represents the divalent radical of an aliphatic 1:2-diol or 1:3-diol at an elevated temperature with triphenyl phosphonium acetylide, reacting the resulting compound of the formula <FORM:0987433/C2/3> at an elevated temperature with a compound or compounds yielding an anion of the formula <FORM:0987433/C2/4> in which R1 represents an alkyl group containing 1 to 4 carbon atoms (for example, with an alkali metal salt of a malonic ester or with a malonic ester and an alkali metal alcoholate), treating the resulting condensation product with an acid to split the ketal grouping, removing any halogen atom present, if desired, by catalytic hydrogenation, and causing a strongly basic condensation agent to act on the compound so obtained with the exclusion of oxygen.  The aldehyde starting materials (ii) are made by condensing an acetophenone or a benzaldehyde with a succinic acid ester, catalytically hydrogenating the alkylidene so obtained, subjecting the latter to ring closure with polyphosphoric acid, ketalizing the resulting tetralone carboxylic acid ester, reducing the carboxylic ester group to the hydroxymethyl group, esterifying the latter group with sulphonic acid chloride, converting the product by solvolysis with an alkali metal cyanide into the nitrile, reducing the nitrile group to the aldehyde and, if desired, splitting the ketal grouping with a dilute acid.  A detailed example is given.

Title: Method or means for driving a drill string or kelly
Inventor: FOSTER JAMES LEWIS
IPC: E21B3/04
Filed: 1970-05-20
Abstract: 1,235,827. Boring earth, &c. J. L. FOSTER. 20 May, 1970 [22 May, 1969], No. 24398/70. Heading E1F. [Also in Division F2] A bushing 20 driving a kelly 16 co-acts with a rotary table 14 to drive the kelly at a speed different from that of the table. The bushing has a housing 22 with a non-circular part engaged in the kelly drive square 26 of the table. The housing is rotated about a ring gear 28 normally fixed against rotation. First stage planet gears 42 journalled to the housing mesh with the gear 28 and a first sun wheel 54. The wheel 54 carries second stage planet gears 58 meshing with the gear 28 and a second sun wheel 70 rotatable relative to the wheel 54. The wheel 70 has splines 78 engaging a kelly drive bush 82 formed by two parts. During drilling, in which the kelly rotates faster than the table, the ring gear 28 is prevented from rotation by brake blocks 100, 102 on a fixed ring 96 engaging a ring 94 fixed to a depending portion 38 of the gear 28. The ring 96 is supported by a fixed ring 118, rotation of the ring 96 being prevented by a hydraulic piston and cylinder device 122. Excessive torque acting on the kelly causes a rise in pressure in the device which rise reduces or cuts-off a supply 114 of air, to release the blocks from the ring 94 to free the gear 28 and render the drive of the bush inoperative. The housing is filled with oil up to the level of a weep hole 150 which supplies oil to the second stage of the gearing whilst a block 152 (Fig. 4) between the support rings 56, 64 of the gears 58 forces oil up passage 154 to lubricate the first stage. In a modification in which the kelly is driven slower than the table the first sun wheel (206, Fig. 6, not shown) is fixed to the housing (202), the first planet gears (214) are carried by the second sun wheel (222), the second planet gears (226) are carried by a sleeve (234) splined to the kelly drive bush (82). In another modification (Fig. 7, not shown) the anchor ring (300) is fixed to the drilling structure, the housing (304) is splined to the kelly drive bushing (312), the second stage planet gears (314) are journalled to the housing, the second sun wheel (318) carries the first stage planet gears (322) and the first sun wheel (326) has a port co-acting with the kelly drive hole in the table. In further modifications the brake blocks are electro-magnetically operated and the bushing has more than two stages of gearing.
