Title: Arrangement for removing debris from a nuclear reactor coolant system
IPC: G21C13/00
Filed: 1975-05-13
Abstract: 1480316 Filter WESTINGHOUSE ELECTRIC CORP 13 May 1975 [20 May 1974] 20097/75 Heading BID [Also in Division G6] A filter assembly 45 for use in a nuclear reactor coolant system undergoing preoperational testing, comprises a base 50 having therein an aperture 54 closed by a fine mesh filter screen 58 and a second, backing screen 60 of larger mesh. Deflection of the screens 58, 60 in the direction of coolant flow therethrough is prevented by providing support at the centre of the screens; this is done by mounting a plate member 64, bearing on the screen centre, on a transverse bar 66 welded across the aperture and to the base 50. Apertures 52 are provided for orienting the base 50 on a nuclear reactor lower core support plate, each aperture 52 serving to receive a dowel pin carried by that plate. Also, the filter assembly 45 is removably securable to the core support plate by means of clamping assemblies. Each such assembly comprises a shaft 74 rotatably mounted in a block 72 and supporting, at its lower end, an offset lug 80. In use; after passing the lug 80 down through an aperture in the core support plate, the shaft 74 is rotated to dispose the lug in overlying relationship with the underside of the core support plate. A locking tab 86 and nut 88 are then threaded on to the shaft 74 to draw the lug 80 against the underside of the core support plate.

Title: Strip transport control
IPC: B21D43/02
Filed: 1959-06-12
Abstract: 953,319. Metal-strip feeds. H. B. F. JENSEN. May 31, 1960 [June 12, 1959], No. 20205/59. Heading B3W. An arrangement for feeding a predetermined length of strip, to a press, comprises auxiliary means to be connected with and to follow the strip through its forward feed and thereafter to be disconnected from the strip and taken back to its initial position and sensing means associated with the auxiliary means for detecting underfeed and to stop the press in the event of underfeed. The invention is shown applied to a press having main and auxiliary punches 12a, 12b and a guide pin 12c secured to a ram 46 operable from a crank-shaft 42 on which is mounted a flywheel 52 driven through a clutch and brake arrangement 54 under the control of a solenoid 56. Strip 16 is fed through the press from a coil 19 by a reciprocating feed device comprising upper and lower members 14a, 14b adapted to be pressed together by means of a pressure cylinder assembly 76 to grip the strip and then to be moved towards the press by another cylinder 80 and later returned after the release of the clamping pressure. The hydraulic or pneumatic cylinder assemblies 76, 80 are controlled by solenoids 77 and 81. Two follower members 18a, 18b are adapted to be clamped to the strip 16 by a cylinder 90 so as to be moved with the strip. Members 18 (a) and (b) normally abut members 14 so as to keep closed an electric switch 20 carried in a recess in the member 18a. In operation the members 14a, 14b feed the strip forward until the member 14b contacts a limit switch 100 whereupon the clamping pressure is released and the members are returned to their starting position, pushing the members 18 (a) and (b) before them. If during the feeding stroke the members 14 should slip upon the strip 16, a gap will be formed between the members 14a and 18a sufficient to permit the opening of the switch 20, thereby causing a relay 60 to open a contact 58 in the circuit of the solenoid 56. This actuates the clutch and brake to stop the operation of the press head. In a modification, Fig. 3, the strip is fed by rollers 32, 34 until the members 18 which are clamped to the strip by a cylinder assembly 90 reach and actuate a sensing device comprising two switches 36a, 36b so that one de-energizes the cylinder 90 and the other initiates the downward movement of the ram. One of the switches may also initiate the return movement of the members 18 through the action of a cylinder assembly at the end of which movement another sensing switch 40 is actuated. Specifications 878,902 and 878,903 are referred to.

Filed: 1960-06-10
Abstract: 894,161. Control of permanent magnet machines; battery-charging systems with variable speed A.C. generators. CIBIE, P. June 10, 1960 [June 16, 1959; Jan. 18, 1960], No. 20579/60. Classes 35 and 38 (4). An A.C. generator having a permanent magnet rotor is regulated by D.C. saturation of part of its stator core. In the form shown in Fig. 1, the stator core between adjacent polepieces is divided into two parallel elements 4a, 4b wound with control windings 6a, 6b. The control windings are series connected in such a sense as to produce flux in a closed circuit 7 which saturates the element 4a and thus prevents flux passing, through the output coils 2. Equal and opposite e.m.f.s. are induced in the control windings by the rotor flux 5 thus having no resultant effect. In one embodiment (Fig. 3, not shown), only one control winding is wound between successive stator poles about element 4a which includes an air gap, but the successive windings are connected in series or series-parallel to produce no resultant induced e.m.f. A three-phase machine (Fig. 5, not shown), in which the stator windings each embrace three adjacent poles and are displaced by one polepiece relative to the preceding winding, has one control winding wound on the yoke between each pair of poles. An electromagnetic control system as in Fig. 4 has two main windings 2a, 2b, connected in parallel through rectifiers 8a, 8b to a battery 9. A shunt winding 11 connected to 2b through rectifier 12 normally maintains contact 14a of the relay blade 13 in contact with contact 15a so that winding 2b is connected through rectifier 8b and series winding 16 to the battery. Should the output voltage of 2b exceed an optimum value blade 13 is attracted to the magnet armature contacting 14b and 15b and causing a saturating current to flow in control winding 6. Winding 2a may be controlled by a known device 17 operating in accordance with the gas evolution of a battery. In Fig. 8 is shown a current limiter incorporating a Zener diode Z. Current is fed from generator winding E through rectifier R to the primary B1 of a transformer. The current induced in the secondary B2 is then fed through rectifier D1 to Zener diode Z and control winding 6 only if it exceeds the breakdown value of the Zener diode, which value is chosen to limit the generator current to a safe value. A voltage limiter using the same Zener diode may also be connected as shown by the dotted lines.

Title: Improvements in the separation of tertiary olefines from gas mixtures
IPC: C07C7/17
Filed: 1936-07-27
Abstract: Tertiary olefines such as isobutylene, trimethylethylene, asymm.-ethyl-methyl-ethylene and their homologues, are separated from gas mixtures by conversion into the corresponding tertiary alkyl halides by treatment of the gas mixtures in the gaseous phase with gaseous hydrogen halides, preferably in an excess of about 10 per cent over the tertiary olefines, at temperatures of 50--120 DEG  C. in the presence of a solid halide of barium or magnesium.  Suitable gas mixtures are those obtained by cracking hydrocarbons, or by the interaction of carbon monoxide and hydrogen, or certain natural gases.  The alkyl halides may be recovered by washing with aromatic hydrocarbons of high boiling point, or by condensation and fractionation, and may be converted into tertiary alcohols or into the olefines, e.g. by catalytic removal of the hydrogen halide with water, followed by removal of water from the alcohol by passage over anhydrous oxalic acid.  The recovered hydrogen halide is preferably used again for the separation.  The chlorides and bromides are preferably used. According to examples: (1) a mixture of 91,5 per cent of butene-2 and 8,5 per cent of isobutylene is mixed with hydrogen chloride and led at 95 DEG  C. over a porous barium chloride catalyst made by drying a mixture of equal parts of crystalline barium chloride and water with hot air to form a vesicular mass. This is broken into small pieces and water completely expelled in a current of hydrogen chloride at 150--200 DEG  C.  The tertiary butyl chloride is extracted by washing with a pseudo-cumol fraction. Magnesium chloride may also be used as a catalyst.  Hydrogen bromide under the same conditions, using either barium chloride or bromide, gives tertiary butyl bromide; (2) a pentene fraction containing trimethylethylene and iso-propylethylene, from an olefine mixture obtained from carbon monoxide and hydrogen under pressure is similarly treated.  The trimethylethylene is recovered as tertiary chloride.
