Title: Circuit arrangement for the switching over of an electromagnet from its actuating current to a holding current
IPC: H01H47/32
Filed: 1974-10-25
Abstract: 1482815 Energizing circuits for electromagnets G KROMSCHRODER AG 25 Oct 1974 [25 Oct 1973 25 April 1974] 46222/74 Heading H2H [Also in Division H3] An electromagnet is supplied from a full wave rectifier connected to an A.C. source through a bidirectional switching element that first conducts for a greater part of the A.C. half cycles to provide a pull-in current and after a time conducts for a lesser part of the A.C. half cycles to provide a holding current. As described a valve-operating solenoid 1 is connected by a bridge rectifier 2, 3, 4, 5 to a triac 7. When A.C. is first applied to terminals 6, 8 each half cycle is almost completely passed by triac 7 because the voltage applied to the trigger diode 11 rapidly reaches the trigger level thereof. After a time determined by timer 11 an electronic or mechanical switch 17 closes and capacitor 16 delays the triggering of diode 11 to a later point in the half cycles reducing the mean current through triac 7 to the holding value of electromagnet 1. Instead of simply timing, circuit 18 may respond to electromagnet current or field strength or movement of the armature. In a modification, Fig. 2 (not shown) capacitor 16 is permanently connected to trigger diode 11 and the timer contact shunts resistor 10 during the initial high current phase of operation. In another embodiment, Fig. 3 (not shown), capacitor 16 is shunted by a transistor which is initially off but after a time determined by a resistor-capacitor circuit conducts to reduce the charging current to capacitor 16 and hence delay the triggering of diode 11.

Title: Improvements in and relating to fuel element assemblies
Inventor: ROBINSON JOHN ALBERT
IPC: G21C19/12
Filed: 1966-10-21
Abstract: 1,130,655. Fuel elements. NUCLEAR POWER GROUP Ltd. 24 Aug., 1967 [21 Oct., 1966], No. 47330/66. Heading G6C. A fuel element assembly comprises sleeve means in which fuel elements are supported, the assembly being adapted for insertion in a fuel channel of a reactor core so as to provide passages for coolant between the walls of the sleeve means and the wall of the channel, the sleeve means comprising two sleeve portions having opposed faces separable from one another to form a space to which coolant can gain access and exert thrusts on the sleeve portions in the direction of the fuel channel axis, one of the sleeve portions being arranged to effect a sliding seal against the wall of the channel adjacent the opposed faces. As shown in Fig. 1, a fuel element assembly 1 is located in a channel 2 in the graphite core 3 of a gas-cooled reactor. The upper part of the assembly lies within a guide tube 4 which extends between the upper surface of the core 3 and a baffle-plate 5. The assembly 1 comprises a stack of graphite sleeves 1a each housing a plurality of fuel elements. Above the sleeves 1a are two further sleeves, an intermediate sleeve 1b and an upper sleeve 1c, which act as a neutron shield. A seal is effected between mutually contacting sliding surfaces of the sleeves 1b, 1c. A tie-rod 6 mounted within the upper sleeve 1c supports the weight of the intermediate sleeve 1b and the fuel elementcontaining sleeves 1a. Coolant gas flows from the space 7 between the core 3 and baffle-plate 5 through openings (not shown) in the guide tube 4 and downwards through the fuel channel 1 over the outer surfaces of the sleeves 1a On reaching the lower end of the channel, the gas flows upwards through the sleeves to enter the space 8 above the baffle-plate 5. The flow of gas into space 8 may be controlled by a gag 9. The use of two sleeves above the fuel elementcontaining sleeves assists in overcoming the upward thrusts exerted by the gas on the assembly being lowered into the fuel channel when the reactor is on load. Gas in the annular space surrounding the sleeves has access to a space 10 formed between opposed end faces 16<SP>1</SP>, 1c<SP>1</SP> of the sleeves 1b, 1c. Sealing rings 11 are located in grooves in the sleeve 1c There is a pressure difference between the gas exerting a downward thrust on face 16<SP>1</SP> and the gas exerting an upward thrust on the lowest fuel element-containing sleeve. The area of end face 16<SP>1</SP> can be made larger than that of the lowest fuel element-containing sleeve so as to increase the nett downward gas thrust on the assembly. In an alternative arrangement, the sleeves 1b 1c are combined into a single sleeve in which case the space 10 is formed between the opposed end faces of the single sleeve and the uppermost fuel element-containing sleeve.

Patterning is produced on a flat bed knitting-machine by the provision of needle blocks 5, 6, 9, 10 containing groups of auxiliary needles which co-operate with the needles of the main beds 1, 2 to produce a superimposed pattern on the fabric produced by the needles of the main beds, Fig. 1. The blocks 5, 9 associated with one main bed 1 are positioned at two different levels as are the blocks 6, 10 associated with the other bed 2, and each block of a pair is capable of being shogged under or over its co-operating block. The blocks, which are moved periodically lengthwise of the machine, cause their wale loop structure to extend at an angle to the wales of the main fabric and when the blocks cross one another a cable stitch appearance is achieved. In addition the position of the blocks can be reversed by elevating one block to an uppermost position and by lowering the other block. By cooperating needle movement a purl or rib fabric can have a plain, purl or rib patterned construction superimposed upon it. Alternatively plain strips may extend lengthwise or at an angle to the fabric. The inclusionof loop transfer mechanism may produce a fashioned fabric which can be bordered by a walewise strip formed by the auxiliary needles. The auxiliary needles may be fed by an additional feeder in conjunction with the main feeder in which case appendages may be formed having one edge knitted into the main fabric but with the remainder of the fabric knitted independently and extruding free from the main fabric.
