Title: Improvements relating to Hoists for Control Rods of Nuclear Reactors
Inventor: DEAN JOHN RAYMOND
IPC: H02K49/06
Filed: 1966-04-25
Abstract: 1,165,137. Winding gear. A. REYROLLE & CO. Ltd. 21 July, 1967 [25 April, 1966], No. 18014/66. Heading B8B. [Also in Division H2] In a motor-driven hoist for raising and lowering a control rod or group of such rods in a nuclear reactor, the driving, e.g. electric, motor 10 is coupled to the hoist via a releasable electromagnetic clutch 13 which comprises a winding 22 which when energized induces a magnetic flux 45 in two coaxial relatively rotatable rotors 24, 28 separated by an air gap 29 defined by opposed rotor surfaces formed by respective sets of similar circumferentially spaced ferromagnetic teeth 42, 44 alternating with non-magnetic recesses, e.g. grooves 41, 43. These effect a locking or synchronous action between the two rotors, whereby the rods may be held stationary in their raised position when the winding is energized and the motor 10 is de-energized, reduction gearing 11 in the drive being irreversible. When the rods are to be inserted into the reactor core the winding 22 is de-energized and the drum 18 unwinds at a speed determined partly by a permanent magnet eddy current brake 15. To raise the rods both motor and clutch are energized. In other embodiments not shown, the teeth extend radially in a planar air gap or at any inclination to the clutch axis. The clutch energizing current may be direct, or alternating in which case its magnetic parts would be laminated. The winding alternatively may be on one rotor and supplied via slip rings.

Title: Improvements in and relating to stocks and dies for use in screwing metals
IPC: B23G5/08
Filed: 1937-06-28
Abstract: 486,998. Stocks and dies. WALKER, J. D., and MATHIESON & SONS, Ltd., A. June 28, 1937, No. 18031. [Class 83 (iii)] In a screwing die-head or stock wherein die sections are moved radially by a bevelled sleeve screwing in the body, means are provided for enabling fine adjustments of the dies to be made, said means being capable of being rendered inoperative in order that coarse adjustments may be effected. The stock body 1 receives a screwed sleeve 4 having a coned end 23 engaging the chasers 38 which are slidable in radial guides in a plate 26 attached to the stock by screws 27 and thumb nuts 28. A plate 6 is rotatable relatively to the sleeve 4 but may be clamped thereto by means of screws 14 and thumb nuts 15 which cause a ring 13 attached by the screws 14 to the plate, to grip the sleeve through conical serrations 16. Rotation of the plate relatively to the sleeve when the nuts 15 are slackened gives a coarse adjustment of the chasers and a fine adjustment is provided by rotating the plate through a lug 11 thereon having a micrometer screw 17 rotatable therein. The head 18 of the screw has a graduated flange reading against a tubular projection 19 of the lug 11 and engages a stop 20a to locate the chasers in the cutting position. The screw 17 is locked by a nut 20, and the stop is adjustable in height, to compensate for different depths of chasers, by means of a set screw 22. The sleeve 4 may be locked in adjusted position by pads on a screw 43 carrying a thumb nut 45, the pads having grooved surfaces for engaging the threads on the sleeve. A circular spring 40 passing through holes in the chasers maintains them expanded into contact with the bevelled end 23 of the sleeve. Bushings and guides.-A work guide 49 is attached by screws 49a to the plate 26 and has V-shaped work-engaging members 47 adjustable radially by means of screws 50 attached to the members, the screws 50 passing through radial slots 49b in the guide 49 and cam-slots 51 in a rotatable cam-plate 52. The screws 50 also serve for locking the cam-plate.

Title: Lip curling method and machine
IPC: B29C57/12
Filed: 1965-04-30
Abstract: 1,064,611. Curling lips of plastic containers. BROWN MACHINE CO. OF MICHIGAN Inc. April 30, 1965 [May 11, 1964], No. 18305/65. Heading B6J. [Also in Divisions B5 and F2] In a process in which curled rims are formed upon plastic containers by passing them between long helically grooved rotating rollers 17, the containers are fed to the rollers at a rate greater than the rate of feed of the containers between the rollers. The containers are thus tightly nested and each individual container is supported during the rimming operation, by the stack, against any excessive deformation. As shown in the Figure, a succession of the containers is fed base downwards between three rotating soft rubber rollers 63 which contact the rims of the containers and each of which is tilted in a direction tangential to said rims (see Fig. 11, not shown) so that the containers are rotated and forced downwards. The containers then pass through a vertical heating tunnel 47 and thence to rollers 17. The angle of tilt of rollers 63 is adjusted so that the above stated condition of feeding is maintained, care being taken to ensure that the peripheral speed of rollers 63 and 17 are the same in order that the stack rotates as a whole. As illustrated in Figs. 13 and 14 (not shown) the apparatus may be used horizontally, a conveyer belt being used to feed the containers to the feed rollers.

Abstract: 1,144,146. Microwave attenuators. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. 27 April, 1966 [17 May, 19651, No. 18527/66. Heading H1W. A high-frequency limiter comprises an element of ferromagnetic thin film arranged parallel to the magnetic component of the transmitted wave and perpendicular to a polarizing field. In the embodiment the thin film 6 is arranged parallel to an end wall of a cylindrical cavity 3 resonating in the TE 111  mode having input and output waveguides 1, 2. A constant polarizing field H is applied along the axis of the cavity. It is stated that power absorption is zero for low levels of incident energy, rises to a maximum and then decreases as the incident power increases. The higher the value of H, the lower the value of incident power at which maximum absorption takes place (Fig. 2, not shown). If several thin layer elements of different characteristics are used, maximum power absorption takes place at several different levels of incident power. The film may consist of an Ni-Fe alloy deposited upon a glass disc by evaporation or electrolysis to a thickness within the range 100-100,000 A.

A portion of the fuel is ignited instantaneously, either by an ignition device or on making contact with the hot walls of the chamber 4, and expels the unburnt portion through the atomizer 7 into the cylinder where complete combustion is effected. In Fig. 2 the atomizer 7 is carried by a moving member 9 which isolates the chamber 4 whilst fuel is being supplied to the atomizer during the compression stroke towards the end of which the member 9 is moved to cut off the fuel supply and to bring the atomizer into register with a narrow passage 11 so that an air blast carries the fuel into the chamber 4 to initiate the action previously described. The moving member 9 may have a sliding or rotary motion.
