Abstract: 732,025. Hydraulic turbines and pumps. ETABLISSEMENTS NEYRPIC. Sept. 3, 1953, No. 24387/53. Classes 110 (1) and 110 (3). The bottom of a semispiral scroll case of a Kaplan or other turbine divides at a point in the case in front of the speed ring into adjacent ramps of different slopes, the one a frontal ramp 12 externally bounded by a wall 1 of the case and upwardly sloped towards a portion of the speed ring comprising a plurality of stay vanes 14 ... 17, starting from the lateral, wall, and ending at the common level of the bottom of the passages between these vanes, and the other a spiral ramp 13 externally bounded by the other lateral wall 2 of the case and forming the sloped bottom of a spiral conduit 20 ending at the level of the bottom of the last of the passages 'between the remaining stay vanes 18. The wall 1 curves inwardly at 10 to act as a first stay vane and the wall 2 finally curves inwardly at 11 to form a last directing surface. The stay vanes are arranged between opposed conical projections 5, 7. The inlet is divided by guides 22, 23. The difference in slopes of the ramps produces a substantially vertical dividing wall 21. The spiral ramp first slopes downwardly to compensate for the decrease in width due to the widening of the frontal ramp. Acceleration of fluid flow occurs in both passages. The invention may be applied to pumps.

Title: Improvements in and relating to band brakes
IPC: F16D49/10
Filed: 1945-09-28
Abstract: 618,582. Band brakes. SELF-CHANGING GEAR CO., Ltd., WILSON, A. G., and MILLER, A. A. Sept. 28, 1945, No. 24663/48. Divided out of 618,500. [Class 103 (i)] To prevent or minimise the application of displacement forces to the drum of a band brake, the brake band is applied by a pushrod through a lever pivoted upon a link connected to the reaction end of the band and so arranged that the line of action of the force applied by the push-rod passes through or near the mounting pivot of the link. Also the line of action of the force in a tension link by which the lever transmits the force to the band passes through or near the pivotal connection between the reaction end of the band and the reaction link and when as described in Specification 618,500 the reaction link is connected through a pair of equalizing levers to another point on the band, the line of action of the force applied by the push-rod also passes through or near the fulcrum of the adjacent equalizing lever. The brake shown in Fig. 4 comprises, as described in Specification 618,500, a primary band anchored by pin 56 to a reaction link 57 mounted on a fixed pivot 58 and which after making one turn counter-clockwise is extended from a point 8 as a pair of secondary bands which lie at either side of the primary band and are connected at their other ends at 64 to an application link 63. A pull is applied to the link 63 to apply the band by a lever 60 pivoted to this link at 56, to link 57 at 61 and to a pushrod 59 at 59<SP>1</SP>. The arrangement is such that when the brake is applied, the axis of the rod 59 passes through the pivot 58 and the line joining the pins 64, 62 passes through the pin 56. The band is positioned and guided by members 41, 42 as described in Specification 618,500. The brake in which as described in Specification 618,500, the reaction link 57 is connected at its lower end to one pair of interconnected equalizing levers instead of to a fixed point, the other of these levers being connected also to a point on the brake band intermediate its ends is also described and shown. It is stated in the Provisional Specification that the brakes may be used in multispeed epicyclic gear-boxes.

Title: Device for regulating the power of a nuclear reactor
Inventor: COSTES DIDIER
IPC: G21C7/14
Filed: 1964-06-15
Abstract: 1,064,382. Reactor control rods. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 15, 1964 [June 25, 1963; Oct. 30, 1963], No. 24697/64. Heading G6C. A neutron absorbing device in the form of a metal chain disposed in a vertical reactor channel has means for displacing it from a withdrawn position, in which it is entirely outside the core, to a deployed position in which it occupies substantially the entire height of the core, and is characterized in that in the withdrawn position it is housed in a detachable container aligned with the channel. The container may be above or below the core; and the chain or chains may be of stainless, boron or cadmium steel. The reactor is graphite moderated, and cooled by CO 2 . The control channel through the top reactor shield 4 has a tubular lining which contains three concrete filled metal plugs 10, 12, 14. Plug 10 houses a winch 24 for handling a cable 26 on which is suspended the absorbing device 90, in this case a plurality of chains 92. The plugs are removable, and are provided with handling grooves 44, 46, 48. Moderator column 58 is lined (62) to provide a control channel 64. The column 58 rests on a core support floor 74 to which is attached a housing 78 for the detachable chain container 84. Orifices 104, 106 are provided in the housing and container to allow coolant flow through both the container and the control channel. A gripping head 96 is fixed to the lower end of the hoist cable and is releasably attached to a chain head 94 by means of cam surfaces on the two heads arranged so that they automatically couple and uncouple (Fig. 4, not shown). To remove the neutron absorber, the chain head 94 is lowered until it rests in seating 98; the loss of tension in the cable releases the coupling and the gripping head 96 is withdrawn into a housing 38. The entire contents of the control channel may now be removed piece by piece (members 10, 12, 14, 66, 62, 86 and 84), and a new neutron absorber inserted. In a second embodiment (Figs. 5, 6, 7, not shown) the container is mounted above the core, and the neutron absorber comprises a single chain controlled by a meshing sprocket arranged above its container. The sprocket and associated driving means may be mounted in either a separate channel plug to that containing the chain container, or in the same plug. In this arrangement, the drive and neutron absorber may be replaced without removing shielding plugs situated below them, thus retaining partial shielding.

Abstract: 1464864 Radiography EMI Ltd 8 May 1974 [23 May 1973] 24773/73 Heading H4F An arrangement for processing data from an X- or γ-radiation scanning apparatus of the type described in Specification 1,283,915, comprises first storage means 13(1)-13(n) for storing electrical signals indication of the estimated absorption (transmission) at each of the plurality of different spatial locations of a slice being analysed which slice is notationally divided into a row/column matrix of such locations, and second storage means 16 for storing electrical signals indicative of the measured absorption for each transverse analysing radiation ray which comprises the absorption over linear combinations of some of such locations, these stored electrical signals being cross-correlated 18(1)-18(n) to update the signals stored in the first storage means by shifting the information stored in each of the storage means at respective rates controlled in dependence upon the disposition of the linear combinations of the locations with respect to the slice. As shown the first storage means comprises a bank of recirculating shift registers 13(1)-13(n), one register for each row of elements in the notional matrix and each register having a storage location for each column of the matrix. The second storage means comprises a bi-directional shift register 16 having a storage location for each row, the correlating being effected in local logic circuits 18(1)-18(n) there being one associated with each row (i.e. shift register 13). A timing arrangement 15 associated with the scanning apparatus is arranged to control storage of the absorption signals (edge readings for each ray) on to a magnetic disc buffer store 14 and then into the shift register 16, the shifting operation of which is controlled by a vertical shift logic circuit 17 itself controlled by timing arrangement 15. The shifting operation of registers 13 is controlled by local logic 18 which receives an input (not shown) from the timing arrangement and passes an output to the circuit 17. By suitably controlling the shifting rates of information held in the stores 13 and the store 16, the movement of information into the store 16 can be correlated with a selected combination of the information held-in the stores 13, thus simulating the path of a given ray through the notional matrix. In the local logic circuits 18 the signals to be correlated are subjected to weighting factors determined by calculation of the degree of overlap between a ray and the successive locations (elements) along its path, the weighting factors production being described with reference to Figs. 4-6, 1 and 2 (not shown), and from further calculations effected in circuits 18 shifting of the information in the store 16 is controlled to re-align the storage locations of the stores 13 and 16.

Title: Improvements relating to underfloor towing-chain conveyors
Inventor: ROOKE SYDNEY WILLIAM
IPC: B61J3/04
Filed: 1961-07-12
Abstract: 956,043. Stops for floor conveyers. SOVEX Ltd. July 11, 1962 [July 12, 1961], No. 25300/61. Heading B7L. An under-floor towing-chain conveyer is provided with stop means mounted on a sloping floor to prevent trucks running back or running away, and incorporates or is connected to buffer means for taking up shocks produced in operation of the stop means. The trucks (not shown) have dogs which engage with the under-floor chain (not shown) through a slot in the floor. The stop means is positioned alongside this slot and Fig. 2 shows a stop means for preventing trucks running back down an inclined floor 1, the trucks being normally driven by the chain in the direction of the arrow A. A stop lever 4 pivoted at 6 projects upwardly into the path of the trucks and will normally be pivoted out of the way by trucks passing in the direction of the arrow A. If a truck runs back down the slope it engages the lever 4 and causes it to abut against a fixed stop 7. The pivot 6 is mounted at the joint of two tie bars 8a, 8b, and the lever 4 will fulcrum about the stop 7 and move to the dotted line position in Fig. 2 causing the tie bars 8a, 8b to slide over fixed supports 11. The tie bars are connected to buffer means (not shown) e.g. a spring to absorb shock and may also actuate a switch (not shown) to stop the drive to the chain conveyer. A series of levers 4 may be mounted at intervals up the slope, the levers being connected by a series of tie bars, as 8a, 8b, to a common buffer means. Alternatively the buffer means may be incorporated in or may act on the lever 4. An alternative form of stop is shown in Fig. 4, wherein the lever 4, when engaged by a truck running back down the slope, acts on buffer means in the form of a wear plate 12 supported on a rubber pad 13. Tie bars 8a, 8b may also be provided to operate additional buffer means and/or a switch as described. A stop means to prevent trucks running away down an inclined floor 1 is shown in Fig. 5 and comprises a pivoted lever 4<SP>1</SP> having a catch 15 pivoted at 16 to its lower end, which catch is held by a light spring against a stop 20. When a truck being driven by the conveyer chain in the direction of the arrow A engages the lever 4<SP>1</SP>, it moves about its pivot 6, the catch 15 remaining in the full line position in Fig. 5. However, if a runaway truck moving at higher speed engages the lever 4<SP>1</SP> the catch is thrown outwardly from the pivot 6 by centrifugal force and it then engages a fixed stop 7<SP>1</SP> causing the tie bars 8a, 8b to move against the buffer means as described. A fixed stop 22 with a resilient bush 23 is provided to reduce shock on arrest of the truck.
