Filed: 1970-11-26
Abstract: 1327630 Fuel elements BABCOCK & WILCOX CO 26 Nov 1970 [26 Nov 1969] 56229/70 Heading G6C A fuel rod assembly includes fuel rods supported by two loingitudinally spaced apart grids, and a control rod guide tube lying parallel to the fuel rods and connected to each of the two grids by releasable connections, each connection being such that it can be effected and released from the side of the grid with which it is associated remote from the other grid, and with both connections released, the guide tube can be removed from the assembly by movement parallel to itself. As shown in Fig. 4, each guide tube 12 is accommodated by a pair of aligned passages extending one through each of the grids 13, 14. The passage 16 that extends through the grid 13 is a smooth bored hole. The passage 18 in the grid 14 is formed in part by a portion 18A of a bore in the grid 14 lying between two shoulders, in part by an internally threaded ring 19 that abuts one of the shoulders and in part by the smooth internal bore of a ring 20 that abuts the other shoulder. The rings 19, 20 are coaxially aligned and fixed to the grid 14 by welding, for instance. The tube 12 is releasably connected to grid 14 by means comprising a threaded shank 21 welded to one end of the tube 12, a threaded bushing 22 cooperating with the thread of ring 19, and a nut 23 screwed on to the shank 21 into abutment with the bushing 22. Releasable connection of tube 12 to grid 13 is effected by means comprising a threaded sleeve 24 welded to the other end of tube 12 and a nut 25 screwed on to the sleeve 24. On assembly, when the tube 12 is introduced into its final position, bushing 22 is slipped over shank 21 and screwed through ring 19 until it bears against shoulder 30 on shank 21. The axial position of tube 12 can be adjusted simply by turning bushing 22 in threaded ring 19. When the desired position has been attained, nut 23 is tightened until stopped by the bushing 22, thereby locking tube 12 in position. Connection of tube 12 to grid 13 is completed by tightening nut 25 until it bears against grid 13. Tack welds W are preferably provided to secure the nuts 23, 25 in place but should it be desired to replace a particular tube 12, such tack welds are easily removed by grinding or chipping.

Filed: 1970-11-26
Abstract: 1322348 Cardiac pacers CORDIS CORP 26 Nov 1970 [28 Nov 1969] 56361/70 Heading A5R [Also in Division G1] Proper placement of the electrode 17 of a cardiac pacer 11 of the type which generates stimulating pulses at a combined input-output terminal 21, to be applied to the electrode 17, under control of spontaneous cardiac signals picked up by electrode 17 and applied to terminal 21, is facilitated by a tester 23 connected between the pacer 11 and the electrode 17, the tester including a network which differently alternates the stimulating pulses and the spontaneous cardiac signals, so that, after the pacer has been implanted (without the tester 23), the decreased amplitude stimulating pulses and cardiac signals are effective. As shown in Fig. 2, the network includes a pair of resistors R1, R2 and a diode Dl, only the resistor Rl attenuating the cardiac signals due to non-conduction of the diode by the cardiac signals, the parallel combination of resistors R1, R2 attenuating the stimulating pulses due to conduction of diode D1 by these pulses. In a modification, Fig. 3 (not shown), a series connection of a zener diode and a further resistor is connected across the resistor R2 so that when stimulating pulses having an amplitude exceeding the threshold of the zener diode are received, these pulses are attenuated by the parallel combination of resistors R1, R2 and R3.

Abstract: 1,236,999. 999. Cleaning metals. BRANSON INSTRUMENTS Inc. Dec.3, 1968 [Dec.7, 1967], No.57280/68. Heading C7E. [Also in Division B3] A method of applying ultrasonic energy to a workpiece 20 immersed in a liquid 19 comprises setting up pressure waves in the region of the workpiece by displacing the liquid with high intensity pulsed energy produced electrically said pulses being at a rate of at least 20, 000 pulses per second, and the duration of each pulse being equal to or less than, one half of the interval between the commencement of successive pulses. The pulses may be produced by switching a source of D.C. potential, applying the pulses to a transducer 15 that moves in substantial correlation with said pulses, and arranging the transducer in communication with the liquid to produce pressure waves in the region of the workpiece. The method may be used for deburring, cleaning, or polishing workpieces, or separating parts. In apparatus described for deburring workpiece 20 the workpieces are placed in a liquid 19 within a plastic walled container 18 which is itself supported in a liquid 17 within a steel tank 16. A transducer 15 is attached to the sides or, as shown, bottom of the tank or placed within the tank and receives pulses from a generator 10 comprising a device for switching D.C. such as a blocking oscillator, multi-vibrator, flip-flop, or tunnel-diode. The D.C. voltage may be 600- 2500 and the pulse rate up to 100, 000 pulses per second or more. The transducer 15 may be a crystal, e.g. a Piezo-electric crystal, or an electro-strictive or magnetostrictive device, and in use operates above its resonant frequency in a pulse range in which it is tuned for a flat response. The liquids 17 and 19 may be water including a wetting agent. The liquid 19 may also include an abrasive material such as ground, powdered, or beaded glass diamond dust, carborundum, or aluminium oxide. The liquid 19 preferably includes an embrittling agent for the workpieces when these are of metal. A hydrogen embrittling agent such as a solution in water of nitric, hydrochloric and phosphoric acids is used for ferrous metals, an oxygen embrittling agent such as a solution of hydrofluoric, phosphoric, and glacial acetic acids for aluminium, and a solution of sulphur dioxide for copper. The liquid 19 may also include a detergent and an oxygen inhibitor. The workpiece may be tumbled during the deburring process. In an alternative method, workpieces to be cleaned are placed in an open basket or tumbler in the liquid 17 which may include a cleaning agent. The method may also be used to separate lenses from a lens block.

Abstract: 1,235,345. Indicating rotor blade failure. CROUZET S.A. 10 Dec., 1968 [12 Dec., 1967], No. 58602/68. Heading B7W. [Also in Division H1] Incipient fractures in hollow helicopter rotor blades are indicated by a pressure-drop detector comprising a switch unit 14 controlled by a flexible wall element 1 which is responsive to pneumatic pressure within a rotor blade (not shown) connected to the duct 7 so that the switch is operated if the pressure in the blade drops as a result of leakage. The device is compensated for ambient temperature variations, and rendered unresponsive to ambient pressure, by arranging the wall element 1 to separate two cavities, 3 and 4, the cavity 4 being in communication with the duct 7, and containing the switch 14, whilst the cavity 3 is closed and contains gas at a pressure substantially the same as that in the rotor blade. The detector is situated at a radius R from the rotor axis 16 such that the centrifugal force (F<SP>1</SP>, Fig. 3, not shown) on the movable end-plate 2 (moved by bellows 1) substantially compensates for the reduction in the force (F) due to pressure drop resulting from the centrifugal force on the gas in the rotor blade. The detector may be tested by unscrewing a cap 13 and pulling out a plunger 10 which seals off duct 7, by slide valve 8, and increases the volume of chamber 4 by compression of the small bellows seal 12 ; this causes a drop in pressure in chamber 4 and switch 14 should operate. Pushing in plunger 10 and fitting the cap 13 restores the normal conditions.

Abstract: 1379779 Hammer printers; magnetic printing LITTON BUSINESS SYSTEMS Inc 20 Dec 1972 [20 Dec 1971] 58810/72 Heading B6F Price or identification tags for sticking to articles of merchandise are printed in strip form with identical information in visual and machine readable form. By means of slidable control knobs 56 type-wheels 52, 52a are rotated which determine the information to be printed on the tags in web form 10 as they pass between the wheels and a transversely located inking ribbon 62 which is impressed by vertically moving hammers 64, 64a. This setting also determines the binary coding to be applied to the tags by magnetic recording members 46, 46a such that when subsequently read by magnetic readers 48, 48a signals from the latter may be directly compared with signals emanating from the positions to which the manually operable knobs 56 have been set. If these signals are not identical a signal is pulsed to solenoid means 76, 76a which, when not actuated, will prevent the hammers 64, 64a moving upwards to strike the ribbon 62 and hence print the tags. A phototransducer device 40 is employed to control the machine, this device detecting notches on the web 10 which delineates tag boundaries. If desired the device 40 may be used to stop the machine if a large number of successive errors occurs. The tags are visually and magnetically printed in two regions hence the pairs of hammers 64, 64a, solenoids 76, 76a &c. An erasure head 38 is provided to ensure that the tag material is magnetically clear before printing.

Title: Wick-type burners
IPC: F23D3/32
Filed: 1973-12-28
Abstract: 1419589 Wick burners MARK RAYMOND PTY Ltd 28 Dec 1973 59905/73 Heading F4T In a burner assembly, e.g. a paraffin heater, having a wick 6, Fig. 1, movable between advanced and retracted positions as by a rotary control knob 26 and shaft 23, inertial means initiate automatic retraction of the wick to extinguish the flame in the event that the assembly is moved. The shaft 23 rotatably supports a casing 27 containing a spiral spring (13), Fig. 5 (not shown). The knob 26 and casing 27 have interengaging drive lugs (30, 30<SP>1</SP>) so that when the wick is initially advanced by rotating the knob 26, the spring is tensioned. It is latched in its tensioned state by a pivoted pawl 29 and remains latched during subsequent retraction and advancing of the wick via the knob 26. However if the burner assembly is moved, the consequent relative movement between a mass 17 and a pivoted lever 14 releases the pawl 29 whereby the spring unwinds and causes the casing 27 and knob 26 to be rotated in the wick retracting direction. The mass 17 may be rigidly or resiliently attached to the lever 14 or it may be suspended, as shown, to provide a pendulum in contact with the lever. The rotary shaft moves the wick via a gearwheel (24), Fig. 4 (not shown), engaged with teeth on one or both sides of an inclined slot in a rigid wick-gripping member. Alternatively the wick may be moved by a lever.

Patent GB-745385-A (GB)
Abstract: 745,385. Pit props. BUSCHMANN, A. March 30, 1953 [April 24, 1952], No. 8654/53. Class 20(2). A two-piece steel pit prop is provided with a frictional locking wedge 3 for releasably securing the shank 1 in an adjusted position, the respective angles of friction at the engaging faces of the wedge 3 being such that upon application of a sudden overload to the prop, the frictional grip of the locking wedge is decreased so that the shank yields to the overloading force. The decrease in frictional grip is due to a reduction in the coefficient of friction between the faces 4 and 5 on the wedge 3 and shank 1 respectively, upon quick downward sliding movement of the shank 1 when the overload occurs, which permits the reaction between the surfaces 6 and 7 on the wedge 1 and locking collar 8 respectively to impart upward movement to the wedge thereby temporarily releasing the shank 1. Normal frictional conditions are restored when quick downward movement of the shank 1 due to overload ceases.
