Abstract: 1,113,736. Controlling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 15 Aug., 1966 [26 Aug., 1965], No. 36449/66. Heading G6C. A mechanism for gradually moving a rod into and out of the core of a reactor for controlling the latter may also function to effect rapid downward movement of the rod for emergency shutdown. If the rod is of neutronabsorbing material the mechanism is situated above the reactor and in an emergency the rod is injected into the core, whereas, if (as shown), the rod is of fissionable material, the mechanism is situated below the reactor and in an emergency the rod is ejected from the core. In one embodiment of the mechanism, Fig. 1, a rod 1 to the upper end of which is secured the rod (not shown), is normally locked to a guide tube 2 by the attraction of an energized electromagnet 4 to an armature ring 28 mounted on the rod 1. A peg 6 co-operates with a helical cam groove 8 so that on rotation of the cam 10 by a motor 12 the guide tube 2 and hence the control rod are moved axially to effect normal control. In an emergency, the electromagnet 4 is de-energized so that a spring 46 acting between a shoulder 48 on the tube 2 and a head 44 of the rod 1 rapidly withdraws the rod from the reactor. To cushion the end of the dropping stroke the rod 1 has fixed thereto a block 45 with a conical nose 50 the nose entering a similar-shaped opening formed between two similar members constituting a slide-block 51. The block 51 is supported on the rod 1 by a spring 54 and studs 55 integral with the nose 50 slide in guideways 49 formed in the block 51. At the bottom of the stroke of rod 1 the block 51 enters a housing 58 and shoes 52 biased by elastic washers 53 frictionally engage the inside of the housing to retard the rod.

Abstract: 820,483. Variable microwave reactances. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 25, 1955 [Dec. 18, 1954], No. 36669/54. Class 40 (8). [Also in Group XL (c)] A variable reactance is provided in a rectangular waveguide by a rotatable twisted vane 3. As shown in Fig. 1, the vane has an electrical length of one-half wavelength and is mounted adjacent the short-circuited end 2 of a waveguide 1. With a 20 degrees twist rotation of the vane, rotation between 0 and 90 degrees provides positive and negative reactances. The vane 3 of Fig. 2, which has a twist of 180 degrees is mounted freely in an insulating carriage 8 and may be continuously rotated by means of compressed air. A difference in frequency between the incident and reflected energy depending upon the rate of rotation is obtained. The carriage 8 is attached by cords 11 to a plate 12 of magnetic material which is held in a desired position in the guide by means of a magnet 13. When it is desired to move the vane, the magnet 13 is removed and the carriage is blown along the guide until it is stopped by a second magnet 14. The vane may be made of a number of radially extending rods or strips (Fig. 3, not shown). It is usually made of metal, but may be made of insulating material where low reflection coefficients are desired.

Title: Fire detecting cable

Filed: 1946-12-12
Abstract: 619,476. Thermal switches. HOLMES, W. G. Dec. 12, 1946, No. 36720. Convention date, July 16. [Class 38 (v)] A fire-detecting cable consists of inner and outer conductors with a series of thermostats distributed along the cable in the space between the conductors. The terminals of each thermostat are connected to the conductors which are thus short-circuited to give an alarm when any one of the thermostats is brought into action under the influence of heat. The circuit is broken when heat ceases to be applied. Fig. 1 shows the end portion of a cable consisting of conductors 1, 2 and a series of thermally-actuated switches mounted on the inner conductor. Each switch comprises a metal sleeve 3 secured to the conductor 1 and a metal ring 6 insulated from the sleeve 3 and making contact with conductor 2 by direct contact and also by metal spring members 12 let into recesses in the ring. A thermostatic metal ring 7 is clamped between the head of the sleeve 3 and insulation 9 and when heated snaps into contact with the ring 6, thus connecting the ring and sleeve and closing the circuit between the conductors 1, 2. Instead of the ring 7, bimetallic star-shaped elements not operating with a snap action may be used.

Title: Improvements in or relating to electrical contact members and processes for producing the same
IPC: H01H1/023
Filed: 1959-11-04
Abstract: An electrical contact comprises a sintered contact layer such as Cu or Ag with a porosity of less than 5%, a carrier such as Cu, and sintered intermediate layer between the contact layer and the carrier having a porosity of 5-20%, said intermediate layer being brazed or soldered to the carrier and being bonded to the contact layer by a powder metallurgical process.  The contact layer preferably consists of an Ag or Cu base alloy containing Cd or CdO and/or Ni, Fe, Cr, Mo, W, the preferred composition comprising Ag with 3-10% Cd and 5-40% Ni.  A layer of the contact material powder and a layer of the intermediate powder are pressed together in a die to give a green composite compact consisting of a 4 mm. contact layer and a 0.2-0.5 mm. intermediate layer.  The compact is sintered in hydrogen at 750-800 DEG  C. to produce a compact with a porosity of 5-20%.  It is then repressed in a fixed die with the movable punch adjacent the contact layer to form a compact which has a contact layer with a porosity of less than 5% and an intermediate layer with a porosity of 5-20%.  The compact is finally brazed or soldered to the carrier.  In a modified method a layer of brazing alloy powder may be applied to the intermediate layer in the original pressing step so that brazing is then effected during sintering.  To limit the diffusion of the material of the contact layer into the intermediate layer, Cr metal powder may be disposed between the two layers in the die prior to pressing.

Abstract: 995,339. Coffee-making machines. IMPERIAL COFFFEE MACHINE CORPORA TION. Sept. 24, 1963, No. 37504/63. Heading A4D. A method for automatically brewing coffee comprises depositing and moistening a first quantity of fresh coffee grounds 84 into a first brewing cup 42, adding additional hot water through a feed tube 16 to form a solution and to wash the solution and grounds into a second brewing cup 48 and, before dispensing the coffee from the second cup, depositing and moistening a second quantity of fresh coffee grounds into the first brewing cup 42. The coffee grounds are fed from a hopper 12 to the cup 42 by means of a feed screw 40 and moistened with a small quantity of hot water from the feed tube 16. The cycle of operations is started by closing a switch which energizes a motor 23 to drive a shaft 26 carrying a set of cams 87. Each cam 87 closes one of the switches 83, 81, 65 and 33 in proper sequence during one complete revolution of the shaft 26 and so starts each separate operation. First a solution is made by adding a flow of hot water to the coffee grounds from the feed tube 16, and as the cup 42 fills, a gravity valve 45 is unseated by a finger 46 and the solution and grounds are washed into the second brewing cup 48. Before the valve 45 is unseated an arm 54 is raised so that a stopper disc 56 closes the outlet 50 of the cup 48 and a ball 57 drops into closing position in a collar 53 of an inner foraminous cup 52. When the valve 45 is reseated the fresh coffee grounds and water are introduced to the cup 42 while the coffee is brewing in the cup 48. After brewing, the arm 54 is half lowered and the liquid dispensed into a receptacle, the arm 54 is then lowered to a pendant position, Fig. 2, which unseats the ball 57 and a flow of cold water is discharged from tube 65 to rinse the grounds from the cup 52.
