Title: Improvements in or relating to fuel elements for nuclear reactors
Inventor: WILLIAMS DAVID WILLIAM
IPC: G21C3/17
Filed: 1960-10-21
Abstract: 913,920. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 12, 1961 [Oct. 21, 1960], No. 36292/60. Drawings to Specification. Class 39 (4). A fuel member enclosed in a protective sheath has a region of preferential initial oxidation on its surface and an element is positioned within the sheath in such a way that an increase in volume on oxidation at this region due to ingress of coolant through a leakage in the sheath causes the element to breach the sheath. The element may be in the form of a plug, of stainless steel for example, a disc of fissile material being disposed above the tip so that a strong signal is received on the fission products detection apparatus immediately the tip protrudes through the sheath. Alternatively, the surface of the element may be roughened to allow fission products to escape freely round it. The sheath may be weakened where it covers the element to make penetration easier. The region of preferential initial oxidation may be produced by a hollow on the outer surface of the fuel member, which hollow may contain an insert of a material more readily oxidizable than the fuel member, e.g. a uranium/platinum alloy containing 1% by weight of platinum. With a tubular fuel member, an element having a bore may extend from a region on the hotter, inner surface across the hollow interior and through the opposite wall, any ingressed fluid present passing through the bore to oxidizing the above region which expands and causes the element to breach the sheath.

Title: Improvements in actions for typewriters
IPC: B41J7/02
Filed: 1934-12-18
Abstract: 437,557. Typewriters. NORTON, C. L., 5, Acorn Street, Boston, U.S.A. Dec. 18, 1934, No. 36323. [Class 100 (iv)] Type-lever actions ; hammer - impression arrangements.-In a noiseless action, means for reducing the speed of the type-levers when approaching the platen is adapted to operate a heavy hammer which is arranged to strike the type-lever when in printing position. In the action shown in Figs. 1 and 8, a hammer 20 consisting of a longitudinally movable rod passes through a fibre-lined guide 21 on a support 25, and is connected to a rock-arm 24 on the support. The hammer is about ten times the weight of one of the type-heads 13, and is normally out of the path of the type-heads. A rock-arm 29 is formed at the top with a fork or universal member 29a in the path of the type-levers 12, and is connected by a link 31 to the hammer. The link 31 and arm 29 are normally in alignment, and are prevented by a lug 31<a> from moving forwards. To compensate for change of case, the arm 29 is pivoted on the aligning-guide 28, which moves with the segment 9, and the support 25 is pivoted at the front to the framework 23, and is mounted at the rear on a rock-arm 27 on the aligning-guide. When any key-lever 11 is depressed, the associated type-lever 12 is swung upwards and, on approaching the platen 14, is checked by the fork 29a, the speed of the type-head being thereby reduced below that at which impact on the platen is noisy. Thereafter, the hammer is, by means of the link 31, depressed, moved longitudinally with accelerated speed, and caused to strike a sharp blow on the typehead to effect impression. For permitting the hammer to complete its stroke by momentum, a loose connection is arranged between the link 31 and the hammer. The pivot 35 of the arm 24 is provided with a hammerreturning spring 34.

Title: Control means in a bar holder and feeder coupled to an automatic machine tool
IPC: B23B13/06
Filed: 1974-08-19
Abstract: 1492989 Bar-stock feeding HAGENUK VORMALS NEUFELOT & KUHNKE GmbH 24 July 1975 [19 Aug 1974] 36397/74 Addition to 1416615 Heading B3B An arrangement of a bar holder C and feeder B coupled to an automatic machine tool, e.g. a multi-spindle lathe A, in which a bar 2b is fed through a collet 88 up to a stop 89, comprises a control means comprising counting means 106 settable to a determined number of machined workpieces; trip means 107 operable when in a set condition to trip the counting means once for each workpiece machined; trigger means 111, 112, 113 to move the trip means to the set condition when a new length of bar is fed into the bar holder; and means coupling the counting means to means controlling the machine tool; said counting means initiating a control signal after said determined number of workpieces have been machined from a length of bar preceding said new length of bar such that for the final workpiece from that bar the bar is still of sufficient length to be safely gripped by the collet 88, the control signal causing the machine tool to stop and cause the feed means 81 of the bar holder C to eject the remnant of the preceding bar from the collet 88 by feeding the forward end of said new length of bar through the collet. During ejection of the remnant the stop 89 is temporarily pivoted out of alignment with the collet against a spring bias by an air cylinder 126. The feeder 81 may be gravity operated by a weight 82 and returned by an air cylinder 87. The distance I (Fig. 2) for the arrangement is known and is divided by the length of each workpiece to enable the said determined member to be ascertained. The trip means 107 only starts to actuate the counting means 106 when the end of the bar passes the position D. Prior to that the trip means 107 is moved laterally by the trigger means 111, 112, 113 so as to miss the actuating element of the counting means 106. For the six bar holders shown (Fig. 5) there are corresponding respective trip means and counting means. The bar holders comprise sets of pivoted levers which together support a bar 2. The levers are separated to allow a new bar to fall therebetween by movement of a slide 225 relative to a support plate 209. The feeder 81 operates to move a sleeve 60 having gripping balls 41 and tapered surfaces which allow it to be pushed backwards over the leading end of a new bar without gripping it, and to grip the bar for feeding when the sleeve is moved forwardly.

Title: An improved machine for enclosing in wrappers, sweetmeats, or other material, in the form of blocks, or slabs
IPC: B65B11/32
Filed: 1920-12-31
Abstract: 177,278. Rose, W. H., (Administrator of Rose, H.), and Rose Bros. (Gainsborough), Ltd. Dec. 31, 1920. Packeting by wrapping-up.- Relates to machines of the kind described in Specifications 20183/00 and 6769/05 for wrapping blocks of chocolate, &c., and consists in the combination, in such machines, of devices such as are described in Specifications 177,477 and 177,478 for feeding to a mould wheel and wrapping blocks &c. with rounded edges and corners and liable to adhesion. The blocks B, Fig. 10, are fed along a trough 7 by an endless band 8 beneath guards 21, as described in Specification 177,477, to prevent riding up. The feed is retarded by a spring-pressed plunger 27 on an arm 22 which bears upon the foremost block but one while a plunger 19 advances and feeds the foremost block into a channel 20 and beneath a hinged piece 29 which prevents adhesion to the plunger. The plunger may be recessed so that only a portion of the end engages the block. The wrappers are fed along a trough 2 and are gripped by known gripping-devices 4, 5, Fig. 6, on a mould-wheel 1 in which an abutment 6 determines the position of the wrapper relatively to the mould. A plunger 30, Fig. 10, then pushes the block past a hinged piece 34 into the path of a plunger 35, Fig. 6, which forces it into the mould, carrying the wrapper with it, and making the folds shown in Fig. 1, the bottom 49 of the mould being forced downwards at the same time. The wrapper is simultaneously disengaged by the jaw 5 being raised by a cam 55. As the mouldwheel rotates, a blade 61 on an arm 58 folds down the part 56 of the wrapper into the position shown in Fig. 2. A guard 67 then turns down the part 57 into the position shown in,Fig. 3. A plunger 70, Figs. 6 and 17, then descends and yielding fingers 68 on a cross-head 69 make the end folds shown in Fig. 4. At the same time, a pivoted blade 78 folds a projecting portion 79 of the wrapper on to the side of the block, this part of the operation proceeding as described in Specification 177,478. The movable side 50 of each mould, adjacent to the blade 78 is shorter than the block, to permit the side portions 78<a> of the blade 78 to engage the wrapper. The portion 82, Fig. 4, is folded down by a blade 81, Fig. 16, and the part 92 is folded down into the position shown in Fig. 5 by a spring-pressed roller 90 carried on a concentric guard 91. The wrapped blocks are ejected from the mould by the movable bottoms 49 being caused to slide radially by a fixed cam 96.

Title: Magnetic data storage device
IPC: G11C11/12
Filed: 1958-11-14
Abstract: 848,292. Circuits employing bi-stable magnetic elements. NATIONAL CASH REGISTER CO. Nov. 14, 1958 [Nov. 18, 1957], No. 36644/58. Class 40 (9). [Also in Groups XIX and XXXVI] An information storage device comprises a resilient wire of electrically conductive, non- magnetic material, e.g. copper, which is electroplated with a ferromagnetic material such as a 28% iron 72% nickel alloy to a thickness of the order of 1 x 10<SP>-4</SP> inches, the ferromagnetic coating being subjected to a torsional stress so that the preferred direction of magnetization lies along a helical path with respect to the longitudinal axis of the wire. The wire is surrounded by a plurality of separate windings 25, 26, Fig. 5, and the coincident application of current pulses to the wire 12 and to one or more selected windings produces resultant stable magnetic fields # 1 , # 2  along the helical path in the vicinity of the separate windings. In this way a number of information bits may be stored at spaced intervals along the wire, and read-out is effected by driving all the magnetic fields into the same direction by the application of a current pulse of sufficient magnitude through the wire. Outputs are then induced in those windings associated with flux reversals. Alternatively read-out of the magnetization state of selected portions of the wire may be effected by pulsing the associated windings and detecting the voltage induced in the wire. A two-coordinate matrix may be constructed by forming the windings such as 25, 26 around a bundle of plated wires. The helical flux path may be established in the ferromagnetic coating 24 by an electroplating operation (see Group XXXVI) while the wire is stretched and twisted. After this operation is completed, the wire is released so that it restores to its initial untensioned state and the torsional stresses are transferred to the plated coating. Alternatively an unstressed wire may be twisted after electroplating and mounted in a clamping frame 28, Fig. 8, which includes wire-securing screws 29, 30.

Title: Position control for a raster scanning a free flowing film
IPC: G09B9/28
Filed: 1972-08-07
Abstract: 1374134 Television SINGER CO 7 Aug 1972 [23 Aug 1971 (2)] 36765/72 Heading H4F A system for scanning a continuously moving film to obtain a video signal for display, e.g. in a - flight simulator, includes an integrator 45, Fig. 4, to which a signal controlling the film drive rate is applied, a summing amplifier 59 which sums the output of the integrator (which represents the instantaneous vertical centre of the film frame being scanned) with the vertical scan signal (V scan) and applies the resulting sum to the film flying spot scanner (or television camera), and a detector arrangement which indicates when the scanned frame begins to move out of the flying spot scanner's raster and resets the integrator 45 to index its output to the vertical centre of the next film frame. The detector arrangement includes a threshold detector 47 connected to the output of the integrator 45 and preset to give an output when its input reaches a value corresponding to the point when a scanned frame begins to move out of range of the scanner's raster, this output is fed together with the vertical blanking signal to an AND gate 49 whose output sets a bi-stable multivibrator 51 which activates switches 55 and 57 to remove the normal scan signals (V scan and H scan) from the scanner and replace them with offset voltages (V off and H off) to drive the scanning spot to the sprocket hole area of the film. In addition when set multivibrator 51, via reset driver 53, causes integrator 45 to integrate towards zero, and the output of a photomultiplier 63 which detects the sprocket holes is counted by bi-stable multivibrators 65 and 67 so that upon reaching a count (i.e. two) equivalent to the number of sprocket holes associated with a film frame provides via OR gate 69 a reset input to bi-stable multivibrator 51 whereby the offsets are removed and a normal scan starts on the next film frame. A second threshold detector 71 is connected to the output of integrator 45 and is set to detect zero voltage and provide a reset input to the bi-stable multivibrator 51, this operates if for some reason sprocket holes are not detected. At slow rates of film movement the raster is susceptible to drift and to compensate for this the raster may be reindexed for each field (Fig. 6, not shown) by detecting during vertical retrace (the scanning spot being offset) the voltage at which a sprocket hole is crossed, and sampling and holding this voltage for use as a correction.
