Title: An improved thread milling machine
Inventor: COOKE FRANK
IPC: B23G1/32
Filed: 1953-06-17
Abstract: 743,551. Screw-thread milling. PASS & CO., Ltd., E. June 17, 1954 [June 17, 1953], No. 16654/53. Class 83 (3). [Also in Group XXIII] A screw-thread milling machine comprises a carrier ring 10 to be secured on the outside of a pipe 14, a tool housing rotatable by a worm drive 16, 18 on the carrier, a drive connection 32 for a cutter 30 adjustable in the housing, and disengageable screw-and-nut means 33, 35 to enable the housing to be fed axially as it is rotated on the carrier. In operation, the carrier is clamped by a split collet 12 to the pipe 14 to be threaded. The tool carrier 24 is then fed manually by screw 25 until a cutter 31, rotated by the shaft 32, pierces the end of the pipe. A plunger 39 locking the housing 11 to the screw-threaded ring 35 is then withdrawn, the screw rings 33, 35 are locked by a grub-screw .(not shown), and the housing 11 is rotated on the carrier by the worm gearing 16, 18. When the end of the pipe has been trimmed, the cutter 30 is fed by the screw 25 to a depth indicated by means 27. The locking-plunger 39 is then engaged and the screw-and-nut 33, 35 freed relatively to one another. Rotation of the worm gearing 16, 18 now causes an axial feed movement of the housing 11 as it rotates, the cutter 30 thus cutting a thread on the pipe.

Title: Improvements in electrical switchgear
IPC: H01H33/12
Filed: 1938-06-03
Abstract: 514,804. Gas - blast switches; actuation of switches. ENGLISH ELECTRIC CO., Ltd., and BLANDFORD, A. R. June 3, 1938, Nos. 16676/38 and 2905/39. [Class 38 (v)] Means for interrupting a circuit comprises in combination a circuit-breaker, an isolating switch in series therewith, means for applying temporarily a force to open the breaker which remains open after the removal of that force, independent operating means for opening the isolating switch after the opening of the breaker and for subsequently reclosing the switch as desired, and means responsive to the initial closing movement of the switch for causing the breaker to close just before the switch closes. In both forms shown, the circuit - breaker comprises a nozzlelike fixed contact 4 normally closed by a movable contact 5, on the stem 5a of which is a piston 5b slidable in a cylinder 6 whereby, when airpressure is admitted to the chamber, the contact 5 is withdrawn against the action of a spring 7 compressed between it and cylinder 6, and the arc thereat is blown out. When the air-pressure is removed, reclosure of contact 5 is prevented, in the case of Fig. 1, by rotating the isolating blade 8 about its pivot 9, whereby a sector 8a on the blade causes a cam-slot 8b therein to move a peg 13 on an extension of the cylinder 6 and retract the cylinder 6 bodily, so relieving the contact 5 of its spring-pressure. The isolating switch is actuated by a link 12 connected to an air-piston so as to be operable after a timeinterval sufficient for extinguishing the arc at 2, 5, and may be reclosed by the same, or a separate air-piston, during which operation the sector 8a restores the cylinder 6 and the spring 7 recloses the contact 5 before the isolating contact recloses. The latter is connected to contact 5 by means of one or more brushes 14 extending from the stem 5a so as to bear on the blade 8 or on sector 8a or on a separate sector forming, together with sector 8a, a forked end of the blade. Alternatively, the cylinder 6 could be fixed and the cam 8b adapted to advance and withdraw a member which is slidably mounted on the movablecontact unit, the spring 7 being arrranged, for this purpose, behind the piston 5b and between an extension on the stem 5a and the slidably mounted part. In the modification shown in Fig. 1, the cylinder 6 is fixed and an extension 17 on item 5a carries a bevelled member 21 engageable by a latch 19, which is pivoted to a fixed bracket 18 and urged into operative position by a spring 20. During the opening movement a projection 8c on blade 8 rides over a spring-pawl @2 on latch 19 without moving the latter, but, during reclosure, the projection initially engages the pawl and deflects the latch to release the movable contact 5. The position of the pawl and projection may be interchanged. The Specification refers also to positive reclosure of the circuit-breaker by the isolating blade.

Title: Improvements in or relating to preparations for combating noxious organisms in agriculture and horticulture
Filed: 1958-05-28
Abstract: A mixture of a -bi and ter thienyl containing small quantities of higher a -polythienyls is prepared by heating 2-iodothiophene with metal, for example silver- or copper-powder.  The a -terthienyl may be obtained by heating a mixture of 2-iodo-thiophene and 2,5-diiodo-thiophene with a metal, for instance copper-powder or by heating a mixture of 2-iodo-thiophene and 5-iodo-21-2-bithienyl with a metal, for instance, copperpowder.  The a -polythienyls may also be obtained by converting 2-halogen thiophenes into a Grignard compound, which is then rteated with anhydrous cuprichloride, e.g. the a -biethienyl may be obtained by treating 2-thienyl-magnesium bromide with anhydrous cuprichloride.  The a -polythienyls substituted by saturated or unsaturated alkyl-groups may be produced by, in principle, analogous methods by starting from suitably substituted thiophene derivatives.  The 5,51 dimethyl-2,21bithienyl may, for example, be obtained by heating 2-iodo-5-methyl-thiophene with copper-powder.  The 5,511-dimethyl-a -terthienyl may, for example, be obtained by heating 5-iodo-51-methyl-2,21-bithienyl with 2-iodo-5-methyl-thiophene in the presence of copper powder.  The a -polythienyls substituted by halogen may, as an alternative, be produced by halogenating the corresponding non-halogen-substituted a -polythienyls.  The 5,511- dibromo-a -terthienyl may, for example, be produced by bromification of a -terthienyl. a -terthienyl may also be obtained by extraction of Tagetes plants, preferably of the roots thereof.  This extraction may, for example, take place by treating the dried roots with ethanol at about 70 DEG C. and by extracting subsequently this extract in a percolator with petroleum ether.ALSO:A preparation for combating noxious organisms in agriculture and horticulture comprises as active ingredients a compound of the general formula <FORM:0880801/VI/1> wherein n represents the value 0 or 1 and the substituents R1, R2, R3 and R4 designate hydrogen, a saturated or an unsaturated alkyl group or a halogen atom, or one of these substituents is a nitro-group, an aliphatic acyl-group or a phenyl-group, or when n = 0, R1, R2 and R4 designate hydrogen and R3 a thiophene-group, mixed with a pulverulent, inert carrier or dispersed in an inert solvent, if desired with the addition of surface-active substances, dispersion agents or adhesives.  Specified active ingredients are 2,21-bithienyl, 5-methyl - 2,21 - bithienyl, 5,51 - dimethyl - 2,21-bithienyl, 5 - chloro - 2,21 - bithienyl, 5,51 - dichloro - 2,21 - bithienyl, 5,51 - dibromo - 2,21-bithienyl, 4,5,41,51 - tetrabromo - 2,21 - bithienyl, 5,51 - diodo - 2,21 - bithienyl, 5 - iodo-51 - methyl - 2,21 - bithienyl, 5,51 - dimethyl-4,41 - diethyl - 2,21 - bithienyl, a  - terthienyl, 5-methyl - a  - terthienyl, 5,511 - dimethyl - a -terthienyl, 5,511 - dibromo - a  - terthienyl, 5-ioso-a -terthienyl, 5,511-diiodo-a -terthienyl.
