Title: Improvements in or relating to nuclear reactors
Inventor: BRADLEY NORMAN
IPC: G21C15/20
Filed: 1959-11-26
Abstract: 910,300. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 9, 1960 [Nov. 26, 1959], No. 40172/59. Class 39 (4). A steam-cooled nuclear reactor of the kind comprising a moderator structure penetrated by a lattice of blind-end channels 3 with fuel elements 5 in the channels and with coolant flow barrier sleeves 4 disposed lengthwise, one in -each channel, to define outer, inflow paths 7 with the channel walls and inner, outflow paths 6 with the fuel elements, has beneath the lower end of each barrier sleeve 4 a baffle 8 so disposed with slight clearance from the channel walls to allow steam condensate to descend the walls past itself and which is shaped to deflect steam coolant flowing down the inflow path 7 up the outflow path 6, means being provided for removing condensate collected below the baffle. A moderator-containing calandria tank 2 is pierced by a lattice of calandria tubes 11 which locate the channels 3 and is divided into three horizontal sections 12, 13 and 14 by division plates 15. Section 14 contains light water as neutron shielding and section 13 heavy water as moderator, whilst section 12 contains a structure of graphite granules 70 and boron steel plates 71 (or a combination of graphite and light water) as neutron shielding. The channels 3 are connected by demountable joints 17 to pipes 16 having inlets 18 and outlets 19 separated by sealing rings 20, the pipes 16 terminating at a charge face 21 and being pressure-sealed by removable plugs 22. The barrier sleeves 4, which are mounted inside the channels 3 by means of spiders 23, support the sleeves 24 housing the fuel elements 5 with the spaces 27 between the sleeves 4 and 24 acting as a thermal insulant between the elements 5 and the channels 3. The upper ends of the sleeves 24 support removable neutron scatter plugs 28 as described in Specification 897,446. The channels 3 are of zirconium and the pipes 16 of steel. Steel condensate outlet pipes 10 are connected to apertures 54 in the lower ends 53 of the channels 3 and have flanges 55 carrying plates 59 which support the baffles 8. The baffles have central drain holes 60. Neutron shield plugs 63 having apertures 67 to accommodate the pipes 10 seal the lower ends of the calandria tubes 11. Stressing of the joints 17 is prevented by the use of guide members 38, described in Specification 910,299, which allow lengthwise movement only of the pipes 16 and channels 3. Recesses 45 formed within these members 38 are filled with graphite granules 61 and boron steel plates 62 to provide a neutron shield. The baffles 8 prevent the outlets 10 from being subjected to the full force of inflowing steam upon start-up and, after a shut-down, prevent entrainment of condensed coolant (since this is collected by way of the drain holes 60) with the steam coolant at the next start-up.

A mechanism for providing power assistance comprises a cylinder and piston 16, 18, a rod 8 projecting through one end of the cylinder for connection to a spool valve 4, means 47 for selectively exhausting one end of the cylinder, and a flow-responsive shuttle valve 30 movable from a mid position whereat full pressure is supplied to both ends of the cylinder to a position blocking flow of working fluid to whichever end of the cylinder is connected to exhaust to avoid excess loss of working fluid. The means 47 consists of a manually displaceable rod having ports 54 to register with ports 58 when the left hand side of the cylinder is to be exhausted and ports 55 to register with the space at the opposite end of the cylinder when the piston is to be moved to the right. The exhaust flows through a bore 56 in the rod and excess loss of fluid is prevented by the shuttle valve interrupting communication between the supply port 28 and the end of the cylinder connected to exhaust. The rod 47 is centred by a spring 69 and its position may be adjusted by a screwed sleeve 61 provided with a lock nut. Should there be a failure in the fluid supply, the piston may be manually actuated by moving the control rod until a snap ring 51 engages a face 53 or the end of the rod engages a face 52.

Abstract: 1,211,123. Triggering circuits for thyristors. ZENTRAALLABORATORIUM ELEKTROGERATE DER VEREINGIGUNG VOLKSEIGENER BETRIEBE ELEKTROGERATE. 26 Aug., 1968, No. 40611/68. Heading H2F. In a circuit for controlling the A.C. power in a load Z 1 , thyristors Th 1 , Th 2  are triggered by pulses derived from a transformer Tr the primary of which is connected to a D.C. supply Ub via an electronic or contact-making switch S and components D 1 , C 1 , R 1  connected as shown. Switch S is synchronized with the alternating supply U and arranged to be opened and closed so as to determine the duration of the conductive phase of thyristors Th 1 , Th 2 . Each time switch S is closed, capacitor C 1  is charged via primary W 1  generating a positive needle-like pulse in winding W 2  which trippers thyristor Th 1 . The duration of this pulse is determined by R 1 , C 1 . During the next halfcycle of the alternating supply U, switch S is opened so that the energy stored in winding W 1  recharges C 1  via diode D 1 , generating a positive needle-like pulse in winding W 3  which triggers thyristor Th 2 . In Fig. 2 (not shown), a single secondary winding provides positive and negative trigger pulses alternately to a symmetrical thyristor.

Filed: 1974-09-19
Abstract: 1461622 Magnetic head switching circuits SONY CORP 19 Sept 1974 [21 Sept 1973] 40926/74 Heading G5R In a magnetic recording apparatus an input signal to be recorded is supplied to each of a plurality of recording heads 30a, 30b and superimposed on respective bias currents supplied to the heads, and means are provided for controlling the amplitude of the respective bias currents so that at any time only one of the heads is capable of recording the input signal. In apparatus in which a first magnetic sheet (6), Fig. 1 (not shown), and a second magnetic sheet (7) are extracted from an envelope (5) and respectively wrapped around 180 degrees of a rotary, axially moving disc (2) carrying video heads (1) and around 180 degrees of a rotary, axially moving disc (4) carrying audio heads (3), 30a, 30b to record parallel video and parallel audio tracks respectively, light passing from an LED 39 to a phototransistor 42 is interrupted, from the time when head 30a starts to leave sheet 7 and head 30b starts to contact sheet 7 until the time when head 30a starts to contact and head 30b to leave sheet 7, by a shutter 38 rotating with disc (4), whereby transistor 49 is switched between ON and OFF states causing transistors 52a, 52b to turn ON alternately one at a time whereby the corresponding head 30a, 30b respectively is effectively switched off because the bias supplied thereto from terminal 36a or 36b is partly shunted via filter 54a or 54b by transistor 52a or 52b respectively. No head switching during playback is thus required. Signals from transistor 43, controlled by phototransistor 42, are shaped by a circuit 45, e.g. a Schmidt circuit, and pass via a delay circuit 46 to transistor 47 which controls transistor 49. The delay of circuit 46 is set to synchronize switching of transistors 52a, 52b to the positions of heads 30a, 30b relative to sheet 7, and a filter 55 smooths the switching pulses to transistor 49 to reduce noise.

Title: Improvements relating to comminuting machines
Filed: 1962-10-31
Abstract: 997,208. Comminuting apparatus. S. H. MILLER. Jan. 31, 1964 [Oct. 31, 1962], No. 41157/62. Heading B2A. A comminuting machine includes a rotatable disc 16, Fig. 1, having at least one slot 19 in which a cutter member 20 is removably mounted so as to present one or more cutting edges standing proud of the disc, and means, in the form of a casing 10, for feeding material to be comminuted on to the disc, the member 20 being of symmetrical form so that it can be removed from its slot and reversed to present a new cutting edge or edges in operative position. As described, the disc 16 is centrally dished and driven by a motor via a shaft 17 to which a disc 21 is bolted to secure the cutter members 20 in position. Each cutter has a body portion 22, Fig. 3, of tapered shape formed with side grooves and an end groove co-operating with the edges of the outwardly tapered radial slot in which the member is mounted. The upper and lower surfaces of the body portion include tooth-like laterally extending ridges 23 which project from the surface of the disc when the cutter is mounted, the leading and trailing end surfaces of the ridges being bevelled or cut away to form sharp projecting edges at the apex of each ridge. The disc 16 extends across an upper compartment 14 of the casing 10 and its periphery is close to an adjacent, fixed, slotted ring 24 through which comminuted material may pass to the lower part of the compartment 14. Inwardly projecting baffle portions 26 are formed in the casing to prevent material rotating in a body on the disc. The cutter member may also comprise a tapered body portion 27, Fig. 6, the upper and lower surfaces of which are each formed with a single laterally extending ridge 28, which has a single trailing cutting edge 29 and a leading cutting edge 30 which may have tooth-like projections 31. The motor may be reversed to clear particles jammed between the opening of the ring 24 and the outer end of a cutter. Where a non- reversible motor is used the cutter members are provided with working faces only on their leading edges.

Title: Miscut mechanisms for shears
Inventor: O'BRIEN JEREMIAH WAGNER
IPC: B23D31/04
Filed: 1964-10-12
Abstract: 1,090,857. Shearing. UNITED ENGINEERING & FOUNDRY CO. Sept. 23, 1965 [Oct. 12, 1964], No. 41645/84. Heading B3W. In the production of metallic strip an edge-trimming shear is positioned immediately in front of the first stand of the finishing train and the edge trimmings pass to scrap-chopping shears which incorporate a miss-cutting device. Should the strip fail to enter the bight of the rolls it is necessary to reverse the edge-trimming shear which comprises pairs of co-operating disc cutters and during the time that the edge trimming shears are running in reverse one of the cutters of the scrap-chopper shear is moved to a non-cutting position. The cutter heads 18 and 19 of the scrap-chopper shear are mounted on crank-pins 28 and 29, respectively, so that the cutter heads have an orbital motion. An arm 31 on the cutter head 28 is connected to the frame 24 of the shear by a pivoted link 33 so that at each rotation of the shear the cutter head moves to a cutting position. A similar arm 32 on the cutter head 29 is connected by a link 34 to a rocker arm 37 which is moved between two positions by a fluid cylinder assembly 39, 41. The extent of the movement is limited by the engagement of surfaces 43 and 44 on the lever with stops 45 and 46 on the frame 24, which define the cutting and misscutting positions.

The polymer may be derived from ethylene and/or propylene, butylene or hexene.  In examples, carbon tetrachloride, benzene and toluene are used as solvents, and pyridine or quinoline and azodiisobutyronitrile are present as catalysts. Specifications 804,535 and 940,197 are referred to.
Patent GB-905625-A (GB)
Title: Improvements in or relating to magnetic data storage devices
Inventor: BRADLEY EDWARD MICHAEL
IPC: H03K3/45
Filed: 1958-12-24
Abstract: 905,625. Magnetic storage devices. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Nov. 4, 1959 [Dec. 24, 1958], No. 41695/58. Class 38 (2). [Also in Group XXXIX] A thin ferro-magnetic film 1, Fig. 1, has two outer switching areas overlapped by respective strip conductors 6, 7, and an intermediate storage area 3 associated with a read-out conductor 5, the remanent state of the storage area being reversed when both the switching areas are brought to the same reversed remanent state by current in their respective windings. The storage area may be restored to its original state by reversed currents in the strips, a read-out signal being induced in conductor 5. In one arrangement it is not possible for a single switching area to have an opposite remanent state to the storage area, and coincident currents in the conductors 6 and 7 are necessary for a reversed remanent state to be stored. This arrangement may be used as an AND gate or may comprise a single storage element in a storage matrix, Fig. 2. As shown, separate films 1 of ferromagnetic material are deposited by vacuum evaporation on to an insulating substrate 2, e.g. glass, and are covered by a vacuum-evaporated layer of insulating material such as magnesium fluoride before the conductive strips are applied by a similar process or by a printing technique. The lower half of each read-out conductor may be deposited and covered with an electrically-insulating layer before the magnetic film is deposited. The conductor upper half is then deposited after the magnetic film is insulated. The films may have areas of different thickness or composition to improve the switching time. In Fig. 2 the conductive strips 9, 10 constitute the row and column conductors respectively, and due to the alternating directions of the row strips it is necessary for currents from the column selection network 12 to be in opposite directions in alternate strips. A modification is described, Fig. 3 (not shown), in which the separate films are replaced by using discrete regions of a continuous film extending over the matrix area. It is stated that non-destructive reading of a storage area may be effected by switching this area only towards the initial remanent state. When the switching current terminates the area is restored to its reversed state, if switched from that state, by the remanent fields of the switching areas. An alternative form of storage element is described in which the switching areas are so dimensioned and composed that each may be reversed in state and remain there when the associated conductor is pulse energized. Under these circumstances the storage area is switched when both strip conductors are pulsed either coincidently or non-coincidently. An OR gate may be formed by a number of storage elements with connected output conductors, each element having a biased switching conductor. Also a single storage element may operate as a AND NOT gate by setting and resetting the storage area. Specifications 880,383 and 882,461 are referred to.
