Title: Improvements in or relating to work holders
IPC: B25B1/10
Filed: 1959-07-04
Abstract: 955,467. Work-holders. G. F. STAPLES. Sept. 29, 1960 [July 4, 1959], No. 23039/59. Headings B3B and B3K. A work-holder comprises a base 10 having securing lugs 11 and keys 55, a fixed jaw 15 keyed to the base at 13, and a sliding jaw 16. Jaw 16 is secured to a member 19 slidable in a slot 25 and against a surface 22 in the base. A jaw actuating rod 26 is dowelled to member 19 at 27, and carries a spring 28 to urge jaw 16 into its open position. A work stop 34 is secured to the base by an adjustable stirrup 35, and passes through an aperture 33 in the rod. A boss 43 secured to the base carries balls 41 which engage arcuate helical cam tracks 40 in a cam 39 rotatable on the rod by a handle 42. In operation handle 42 is brought forwardly down from the position of Fig. 1, to bring balls 41 into the shallow end of tracks 40. A stop 30 is retracted from end 32 of member 19, and nuts 44 are retracted to allow spring 28 to open jaw 16 and the workpiece is inserted between the jaws. Nuts 44 are screwed up to cam 39 and stop 30 is screwed inwardly until it is just clear of end 32 to limit subsequent movement of jaw 16. Upward movement of handle 42 will move jaw 16 into the clamping position due to balls 41 riding up cam tracks 40. Cam 39 has opposite hand cam tracks on each side to allow reversal of the cam for opposite hand work-holders to enable handle 42 to be moved in the same direction irrespective of the hand of the work-holder. A slidable template 48 can be used for locating previously machined faces on the work, in the required position for subsequent machining. Specification 773,882 is referred to.

Patent GB-586583-A (GB)
Title: Improvements in or relating to automatic resistance measuring arrangements
IPC: G01R27/02
Filed: 1944-11-22
Abstract: 586,583. Resistance measurements. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and HOPLEY, H. E. Nov. 22, 1944, No. 23171. [Class 37] An unknown resistance to be measured is connected in circuit with a known resistance and a source of current in such a manner that an inductive kick is applied to the grid of a grid controlled gas discharge tube causing it to strike if the unknown resistance differs from the known resistance in one particular sense. A Wheatstone bridge has resistance arms YD, YF, Fig. 1, of 100 ohms, arm YG of 25 ohms, and arm YE containing the resistance under test. Connected across one diagonal of the bridge is the primary of a transformer T1, and a switch S1. The secondary of the transformer is connected via a resistance YC to the grid of a grid controlled gas discharge tube GDT1. The filament current of the tube is derived from a 50 volt supply through the resistors YA, YB, which raise the potential of the filament with respect to the grid and thus provide a standing negative bias on the grid. If the value of the unknown resistance YE is less than 25 ohms when the switch S1 is closed a current flows in the primary of the transformer in such a direction that during its build up time a voltage is induced in the secondary of such polarity as to oppose the standing negative bias on the grid of the tube GDT1. This thereupon strikes and operates a relay A which sends a signal through line 10. If resistor YE is exactly 25 ohms, no current flows in the transformer and the tube does not strike. The same circuit can be used to give a signal if resistor YE is greater than 25 ohms by reversing the connections of the secondary winding. In a modification the centre of the secondary winding is earthed and the ends of the winding are connected to.the grids of a pair of gas discharge tubes, one of which operates if the unknown resistance is greater than the known resistance and the other if it is less. In a further modification the known resistance comprises a variable resistance TR, Fig. 3, having a wiper AS1. When contacts S1 are closed tube GDT1 strikes and operates relay A which energizes a uniselector magnet ASM and opens the primary circuit at its contact A2. Magnet ASM opens contacts ASMC and brings the relay back to normal, whereupon magnet ASM deenergizes and steps the wipers AS1, AS2. Interaction between relay A and magnet ASM continues until balance or slight overbalance is obtained. The resistance value inserted when the bridge is balanced is indicated by the lighting of the appropriate one of a group of lamps over wiper AS2 and leads 10-24. A 50-point switch, or two switches in tandem may be used to obtain a greater range, and a fixed resistance approximating to the resistance to be measured may be connected in series with the variable resistance, the steps of which may then be very small. A number of unknown resistances of the same nominal value may be connected in turn by a step-by-step switch, an alarm being given when one differs sensibly from the nominal value.

Title: Means and method of changing the neutron density curve across a nuclear reactor
IPC: G21C7/00
Filed: 1945-09-11
Abstract: 847,902. Nuclear reactors; handling nuclear reactor fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 11, 1945 [Sept. 5, 1944], No. 23449 /45. Class 39(4). In order to produce a uniform distribution of neutron densities and temperatures throughout a nuclear reactor the reproduction factor is a function of radial distance from the centre. This is effected by placing different sized fuel elements in different zones in the reactor, the separation of the elements throughout the reactor being uniform. In alternative arrangements, the individual fuel elements in a single channel may be separated by graphite spacers to give the required reproduction factor or elements of different composition may be employed. As shown, in a nuclear reactor, consisting of a cubic mass of graphite blocks 10, cylindrical fuel elements of natural uranium are inserted in horizontal channels 12 and in the graphite, through which cooling air is forced. A control rod 41, of cadmium or boron, is movable perpendicularly to the fuel alignment and neutron density values are registered by an ionisation chamber 80. The channels carrying the fuel elements are confined to the cylindrical volume A. Each fuel element 35 consists of a uranium rod 36 inside an aluminium can 37. The can is closed by the cap 38, the edge of which is welded to the can and span over. Elements 35 are inserted into the reactor channels from magazine 52 by the plunger 54. 52 is raised and lowered on elevator 57 which is movable laterally across the vertical shield 24. To unload elements from the reactor, they are moved by 54 to the outlet face 15 into chamber 31 from which they pass, through valves 92, 94 to the containers 101 in the chamber 95. Magazine 52 is of iron or lead and has thick walls which act as radiation shields. Plunger 54 is motor driven through friction wheel 74. Damage to the fuel elements in falling into 31 is prevented by pad plates 90 of cotton or wood. Crane 106 places caps 107 in containers 101. Before unloading, the upper portion of pipe 109 is filled with water from inlet pipe 109. Specification 817,752 is referred to.
