Abstract: 1,228,016. Hose reels. POCLAIN. 27 June, 1968 [28 June, 1967], No. 30723/68. Heading B8M. A device for winding a flexible pipe comprises a drum 10 supporting a flexible pipe 9, a fixed support 11 on which the drum is rotatably mounted, an hydraulic motor 14 coupled to the drum, an hydraulic receiver e.g. a double acting jack for a grab or bucket, fed by the pipe and movable with respect to the support 11, a twoway flow selector 19 between a fluid source 16 and the motor 14, the movement of the selector 19 being dependent on the direction of movement of the receiver relative to the support 11, a first conduit 18 delivering fluid during winding of the pipe, a first calibrated valve 22 in the conduit 18, a second conduit 21 delivering fluid during unwinding of the pipe, and a second valve 23 calibrated at a pressure less than the valve 22 in said conduit 21, the two conduits having a common point 30 located downstream of the valve 22 and upstream of the valve 23. During winding of the pipe, a contact 26 of an electromagnetic circuit is closed and the selector 19 connects the fluid source 16 to the conduit 18, the valve 22 being set to provide a torque on the motor 14 which corresponds to a tangential force at least equal to the weight of the pipe 9. Thus the pipe is wound under constant tension, excess fluid being returned to the source 16 via the valve 23. When the pipe is unwound, the contact 26 is broken and the selector 19 connects the motor 14 to the source 16 via the conduit 29, 21. In this case, the motor 14 is driven by the rotation of the drum 10 due to the pull of the pipe 9 and fluid is fed through the motor, the calibrated valves maintaining the correct pressure of fluid to tension the pipe 9.

Abstract: 1,230,233. Automatic turret lathes. INDEX-WERKE K.G. HAHN & TESSKY. 29 Aug., 1969 [31 Aug., 1968], No. 43195/69. Headings B3B and B3T. In an automatic turret lathe the tool turret 16 is mounted on a slide 10 which is actuated by a rack 62 and segment 68 to feed the turret to the work and which is returned by a spring 72, the rack being movable relative to the slide whereby when the turret slide is fully retracted the rack is moved back to a further extent to effect release of the turret clamping means and permit indexing of the turret. A stop carrier 52 carried by the slide is indexable with the turret and carries adjustable stops 54 which selectively co-operate with a fixed stop 14 on the slide through which the slide feed motion is transmitted from the segment through the abutment 70 on the rack. The release of the toothed coupling members 26, 28 between the slide and turret respectively is effected by engagement between a cam 74 on the end of the rack and a follower 75 on a lever arm 55 when the rack is retracted to the further extent, the pivoting of the lever 55 and its arm 42 axially displacing the turret shaft 18 thereby disengaging the teeth of the coupling members 26, 28. The indexing of the turret is then effected by gear means 58, 56 which rotate the stop carrier 52 which is connected to the turret by shaft 50 and bevel gears 46, 48. Fluid-actuated means 78 is also connected by lever arm 82 to the arm 42 to effect a small retraction of the cutting tool 76 to prevent marking of the workpiece prior to the retraction of the turret slide, the means being actuated in timed sequence in the machining cycle. A spring-biased pin (84), Figs. 3 to 5 (not shown), is provided to maintain positive engagement with the toothed coupling ring 28 to prevent excessive back-lash between the coupling elements during retraction of the turret. The control of the speed of rotation of the cam drum 92 to which the segment 68 is attached may be effected independently or in combination from motors 96 and 108 through spur and epicycle gearing respectively, depending on the precise speed control required. The indexing of the turret and stop carrier being effected from the cam by way of a maltese cross mechanism 106.

Abstract: 1,250,077. Boring earth and rock. TRUSTUL DE FORAJ PITESTI. 10 Feb., 1969 [9 Feb., 1968], No. 7135/69. Heading E1F. A vibratory device for insertion in a drill string to free the, string when seized in a borehole produces repeated hydraulic shocks by periodical interruption of the circulating fluid. The device comprises an outer cylindrical body 1 having a valve seat 8 supporting a valve portion d of a tubular vibrator member 2, 3 reciprocable within the cylinder 1 and having a valve 4 therein which is biassed away from its seating j by a spring 6. The lower portion h of the vibrator member fits sealingly over a hollow member 10 at the bottom of the device. In use, the device is dropped down the drill string, its fall being retarded by resilient strips 16. After the stepped portion of the member 10 comes to rest in the drill collar, drilling fluid is pumped down the string and through the central bore of the vibrator member 2, 3 to thrust the valve 4 on to the seating j, thus producing an hydraulic shock which is transmitted to the drill collar. The increased fluid pressure behind the valve 4 causes the whole vibrator member to lift and valve d to open. Drilling fluid then flows round the exterior of the vibrator member and through openings k whereupon the valve 4 opens and the vibrator member rebounding from a resiliently mounted member 12 falls back to its original position.

Abstract: 1295800 Reactors WESTINGHOUSE ELECTRIC CORP 20 Oct 1971 [30 Dec 1970] 48792/71 Heading G6C In a pressurized water sucker reactor, the coolant water is monitored for N16 gamma emission, induced by neutron irradiation of O16 in the coolant. The build-up effect of N16 activity in the coolant is neutralized by subtracting a simulated build-up signal from the measured signal. The resultant represents the reactor power and closely follows the power charges. The build-up effect occurs when the transport time in the reactor coolant loop is too short to allow for the complete decay of the N16 activity before the coolant returns to the core. The ion chamber N16 detector, 10, supplies the signal 16 to the amplifier 12 coupled to the indicator 22. The build up simultator 14 provides the build-up function which is subtracted from the detector signal 16. In a modification, a further feed-back loop is incorporated which simulates the build-up of the N16 activity round the loop as it occurs due to cycling.

To effect control of the drive, the worm 5 which is engaged with the wheel 2 is rotatably and slidably mounted on a shaft 6 in the slide, the shaft being driven from a gear 7 attached thereto, a double ended dog clutch 8 being engaged between the gear 7 and worm 5 to transmit the drive to the wheel 2. A spring 12 on the shaft 6 urges a thrust member 13 into engagement with the worm to retain the clutch 8 in engagement with the worm 5 and the gear 7 against the opposing pressure of the spring 11. In operation the drive is transmitted from the gear 7 via the clutch 8 to the worm-wheel 2 and then to the tool slide. As the slide abuts the stop 28 on the bed of the machine the wormwheel 2 stops but the drive gear 7 continues to rotate and as a result the worm 5 is axially displaced along the shaft 6 against the spring 12 by the action of the worm 5 rolling over the teeth of the worm-wheel 2. The axial displacement of the worm effects disengagement of the large teeth 9 and 9a between the clutch and worm and the subsequent disengagement of the small teeth 10, 10a between the clutch and drive gear 7, the traverse of the tool carrier being automatically stopped. The worm may be returned to its operative position by a control handle (not shown). The embodiment in Fig. 2 is operative for one direction of rotation only of the worm. In the embodiment in Fig. 3 the drive may be automatically stopped with rotation of the shaft in either direction.

Abstract: 1316942 Radar EMI Ltd 17 March 1970 [2 April 1969] 17251/69 Heading H4D In an M.T.I. pulse radar system the area scanned is divided into portions each comprising a plurality of the smallest resolvable elements and the presence of one or more moving targets in a portion results in the transmission of a single output signal. This signal is a quantized, digitized representation of the largest target signal received from that particular portion. In the absence of a target in a particular portion an output signal is sent which is indicative of the map breakthrough (i.e. terrain contour) data in that portion. In a first embodiment, Fig. 1, high resolution data is stored in a storage tube 2 in an aircraft cockpit and taken off by a reading circuit 5 which executes sub-scans within a scanned portion and feeds a signal train to an M.T.I. detecting and peak clamping circuit 6 which in turn feeds a signal, derived from the largest target signal in any sub-scan of a portion, to a quantizing and digitizing circuit 7 and hence to the ground base over a VHF link. The signal train from a scanned portion is also fed via an integrator 8, to a second quantizing and digitizing circuit 9 and hence to the VHF link. A buffer gate 10 and shift register 11 are interposed between the digitizers 7, 9 and the VHF link 11 and in the absence of a target within a scanned portion a signal is transmitted representative of the map breakthrough data for the portion as a whole. In a second embodiment (Fig. 2, not shown), the data stored in the storage tube is scanned in the form of a non-interlaced T.V. raster and the output signals derived thereby are gated to provide the effect of sub-scanning and the resulting signals fed via a sequential switching arrangement to a number of analogue integrators each being connected in parallel to a corresponding peak clamping circuit as in the first embodiment. In an alternative method of achieving reduction of resolution, full resolution scanning of the portion is undertaken to note the presence and coarse amplitude of all targets, which may also be counted. The resolution of the reading beam is then reduced, as by a factor of nine, and the portion scanned again. The resulting signals are processed as before.
