Abstract: 590,796. Copying by milling. DRONSFIELD, S. W., and DRONSFTELD BROS., Ltd. Dec. 7, 1944, No. 24518. [Class 83 (iii)] In a milling-machine for copying, particularly suitable for machining the ends of carding engine flats, the work 4 is carried by a table 15 angularly adjustable about a pivot 16 so as to bring each end in succession beneath the cutter 23 which is mounted on a lever 26 pivoted at 27 and provided with a tracer 51 engaging a pattern 52. The pivot 27 is carried by a slide 28 movable in guides 29 on the machine frame 30 by means of a screw 32 rotatable in the frame and engaging a half nut 33 in a bracket 36 attached to the slide 28. The ends of the work are held' upon interchangeable brackets 12, 13 attached to members A which are radially adjustable on the table 15 to suit the length of the work and the pivot 16 of the table is adjustable on a fixed guide 18 to bring the end of the work under the cutter. The feed nut 33 is moved into and out of engagement with the screw 32 by a bell-crank lever 34 pivoted at 35 to the bracket 36 and operated by a push rod 38. In operation, the end of the work to be machined is positioned by a stop 64 on the member A engaging a fixed step 59 and is held there by a screw clamp 61. An electric motor 47 is then started to drive the cutter through a belt, and also to drive, through another belt, the worm gear 44 for rotating the screw 32. The slide 28 is positioned at the inner end of its stroke by an adjustable stop 40 and the nut 33 is engaged with the screw by pulling on the rod 38. The slide 28 is then traversed to move the cutter across the work and is fed vertically in accordance with the pattern 52 by the tracer 51. At the end of the operative traverse, a collar 41 on the rod 38 may stop further movement of the rod to disengage the nut or alternatively the bracket 36 may engage a micrometer limit switch 66 to stop the motor 47. The slide 28 is then returned by pressing :on a handle 63 attached to the tracer head. 51<1>, thus tilting the head about a pivot 55 as limited by an adjustable stop 57, and causing the tracer to swing the lever 26 to raise the cutter from the work. The table 15 is then rotated to bring a second stop 64 against the other end of stop 59 to position the other end of the work for machining. The nut 33 may be held yieldingly in operative and inoperative positions by a spring latch 42 and the tracer 51 is adjustable relatively to the cutter by a micrometer 50 and is clamped by a screw 54. The pattern 52 may be replaced by one of different shape for machining the other sides of the work.

Filed: 1957-08-02
Abstract: The invention comprises derivatives of pyrrole, benzopyrrole and dibenzopyrrole having an alkanoyl or phenylalkanoyl group attached to a nuclear carbon atom and a dialkylaminoalkyl group attached to the nitrogen atom of the pyrrole ring, and acid addition salts, quaternary ammonium salts and oximes thereof.  The preferred products comprise pyrrole and indole derivatives having the alkanoyl or phenylalkanoyl substituent in the 2-position and carbazole derivatives having the alkanoyl or phenylalkanoyl substituent in the 3-position.  Suitably the alkanoyl or phenylalkanoyl group is an acetyl, propionyl or phenylacetyl group and the dialkylaminoalkyl group is chosen from dimethylaminoethyl-, diethylaminoethyl-, g -dimethylaminopropyl- and b -dimethylamino-b -methyl-ethyl groups. The compounds are prepared by condensing an alkanoyl- or phenylalkanoyl-substituted pyrrole, benzopyrrole or di - benzopyrrole with a dialkylaminoalkyl halide, such as the chloride, in the presence of an alkaline condensation agent, such as sodamide or an alkali metal or alkali metal hydride, hydroxide or carbonate, in an organic diluent, for example, toluene or dimethyl formamide.  The reaction is suitably carried out in an inert atmosphere, for example under nitrogen.  The products, which are used therapeutically, may be converted into acid addition or quaternary salts or into the oxime of the carbonyl group by conventional methods.  In examples, there are prepared 2-propionyl-1-g -dimethylaminopropylpyrrole; the 1-g -dimethylaminopropyl-, 1-b -dimethylaminoethyl-, 1 - b  - methyl - b - dimethylaminoethyl- and 1-b -diethylaminoethyl-, 3-propionyl indoles; the 9-g -dimethylaminopropyl-, 9-b -dimethylaminoethyl- and 9-b -dimethylaminopropyl-, 2-propionyl carbazoles and the 3-acetyl- and 3-phenylacetyl derivatives of 1-b -dimethylaminoethyl-indole; also the acid addition salts, such as acid maleates, the quaternary compounds, such as the methiodides, and the oximes of the above compounds are prepared.

Title: Improvements in aircraft arresting gear
IPC: B64F1/02
Filed: 1967-05-31
Abstract: 1,239,917. Aircraft arresting gear. MACTAGGART, SCOTT & CO. Ltd., and J. C. MATTHEW. 19 Aug., 1968 [31 May, 1967], No. 25095/67. Heading B7G. [Also in Divisions F1 and F2] An aircraft-arresting rope or net (10, Fig. 1, not shown) is attached at each end to a flexible belt 11, Fig. 2, toothed on at least one side and passing through a casing 14, Fig. 3, having inlet 17 and outlet 19 ports for hydraulic fluid and means 15, 16 whereby fluid delivered adjacent to the gaps between the teeth 13 of the belt is thereafter pumped out through the outlet port 19, the back pressure of the fluid and thus the retarding force of the arresting gear being regulated by valves 24. In the embodiment of Fig. 3 the casing 14 contains toothed wheels 15, 16 mating with the teeth 13 on the belt so that the wheel, belt and casing constitute a gear type pump. There may be a series of four such pumps 18, Fig. 2, on each side of a belt with teeth on both sides and delivery of each pump passes to a valve 24. The outlet 22 of each series of pumps is connected via a cooler 23 to the inlet 21. Alternatively the pumps may be connected in parallel. The inlet and outlet ports of opposite pumps are interconnected to prevent bending of the belts. The cooler is connected to a reservoir 24a. Between a bin 25 for storing a belt and the series of pumps 18 are gear type pumps 32 which have ports connected to an accumulator 34 and ports connected to the reservoir 24a. At each end of the casing 14 are sealing rotors 48, 49 which have non- return valves 50 between them and the rest of the hydraulic system so that in use fluid is transferred from the reservoir 24a to the accumulator 34. Subsequently a resetting valve 33 is opened to enable the fluid to return to the reservoir via pumps 32 thus restoring the belt to its original position to catch another aircraft. In another embodiment, Fig. 5 (not shown), the teeth of the belt (11) are protected by two additional intermediate belts (37, 38) which are peeled off before the belt (11) goes through the casing and are joined to it again afterwards. In a further embodiment, Fig. 6 (not shown) protection is afforded by separating back-toback belts (39, 40) emerging from the bin and casing, reversing them round pulleys (42, 43) to pass back around the casing and thereafter reengaging them interlockingly face-to-face for connection to the rope or net. In an alternative embodiment, Fig. 4 (not shown) a composite belt formed of a pair of belts (11a) and (12a) with intermeshing teeth (13a) is passed through an elongated casing composed of upper and lower guide bars (25, 26) and side plates (27, 28). In use the two belts are separated and drawn together at intervals by blocks (29) and constrictions causing the two belts to act as pumps.

[Also in Division H3] A Schmitt trigger TR2, TR3 is switched by the presence of an alarm signal at the input 1, 2 of a driven stage TR1 to light a lamp L. The supply at terminal 6 fluctuates between -18V and -12V so that lamp L will flicker. Voltage developed across lamp L causes a second transistor TRX to conduct and energize a relay operated audible alarm G. This alarm may be cancelled by means of a thyristor TH1 which is turned on by a "Cancel Audible Alarm" push-button 7 and maintained in the "on" condition by voltage from lamp L. Thyristor TH1 also connects lamp L through a diode D4 to a steady -18V source so that it will indicate the alarm condition but will not flicker. A plurality of visible alarm circuits may be connected to a single audible alarm G so that the audible alarm may be cancelled in respect of one visible alarm while this visible alarm is maintained in a non- flickering state and yet the audible alarm is available from any other alarm point.
