Title: Improvements in or relating to ring spinning machines
IPC: D01H1/36
Filed: 1958-12-09
Abstract: 852,980. Builder motions for spinning machines. BREVETS AERO-MECANIQUES S. A. Dec. 9, 1958 [Jan. 7, 1958], No. 39714/58. Class 120(2). In a ring spinning machine a reciprocating rail carrying either the rings or the spindles is at least partially balanced by a spring or springs, the variation in the action of the spring(s) consequent on raising the mean position of the rail being at least partially corrected. A wheel 13 reciprocated by a cam 5 traverses the rail 1 through a chain 10, shaft 8 and chain 4. A second cam 14 intermittently shortens the effective length of the chain 10 by rotating a shaft 12 through a lever 15, ratchet and pawl 17, 20 and a worm wheel 23, to displace the mean position of the rail 1. In the form shown there is one balancing spring 24 which is attached at one end to the shaft 12 and at the other to a drum 25 connected to a drum 27 keyed on the shaft 8. The drums 25 and 27 have the same diameter so that each displacement of the mean position of the rail is compensated by an equivalent rotation of the spring 24, the action of which is thus constant throughout the winding operation. The inner end of the spring may be connected to a member rotating in unison with the shaft 12 and the outer end directly to the chain 4.

Title: Method of controlling a nuclear reactor
IPC: G21C7/30
Filed: 1965-09-20
Abstract: 1,057,529. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 20, 1965 [Dec. 24, 1964], No. 40056/65. Heading G6C. A nuclear reactor comprises a plurality of spaced elongated fuel assemblies disposed around a central axial fuel assembly and means for rotating the spaced fuel assemblies around the central fuel assembly to control the reactor, the amount of rotation being a maximum at the upper ends of the fuel assemblies and decreasing to zero at their lower ends. In one particular arrangement (Figs. 1 and 2, not shown), fuel assemblies 40 are disposed around a central assembly in concentric hexagons. Each fuel assembly 40 has a hexagonal central section 41 blending into an upper cylindrical section 42 and a lower tapered section 44. The cylindrical sections 42 fit loosely into holes 22 in an upper support plate 20 and the tapered sections 44 rest in tapered holes 14 in a lower support plate 10. The upper plate 20 is rotatable by means of a pinion gear 32 meshing with gear teeth 30 around the perimeter of the plate 20. Initially, the plate 20 is rotated until the holes 14, 22 are in alignment and the fuel assemblies 40 are then inserted through the holes 22 until brought to rest in the tapered holes 14. In this position the reactor is not critical. Coolant connections are made using flexible tubing with coolant inlet tubes 46 and coolant outlet tubes 48 and coolant, which may be a liquid metal, is passed through the fuel assemblies 40. Criticality is obtained by rotation of the plate 20. As burn-out progresses. criticality is maintained by slightly increasing the rotation of the plate 20. The invention is applicable to both thermal and fast reactors. It may be used as a simple means of producing an oscillating reactivity change for reactor physics testing, or as a means of producing controlled bursts of very high flux levels.

Title: Improvements in or relating to method and apparatus for measuring and controlling moisture in a sinter mix
IPC: G05D22/02
Filed: 1961-11-14
Abstract: <PICT:0995352/C1/1> <PICT:0995352/C1/2> The moisture content of a mix to be sintered is controlled at a predetermined value by means determining its bulk-density and comprising a detector 25, measuring the absorbtion of gamma rays omitted by source 23, Fig. 1, by the moistened mix and giving an indication of the moisture content of the mix by means of the graph of Fig. 4.  Where the moistened mix is to be pelleted before sintering, the optimum moisture content is near the point of minimum bulk density and is sought and maintained by feeding the output signal from the detector to a computer 24 which stores this signal and causes the flow controller 39 to alter the water supply to spray 15 and so change the bulk density of the mix. The new output signal of the detector is compared with the previously stored signal and the resulting signal causes the computer to alter the water flow towards that giving the required minimum bulk-density. The computer may be omitted if only semi-automatic seeking of a moisture content other than that giving the minimum bulk-density is required. In another embodiment, Fig. 2 (not shown), wherein any moisture content can be automatically sought and held, two gamma radiation sources and detectors are arranged to measure the bulk density of the mix before and after the addition of a small constant amount of water, so as to determine the rate of flow of the nearly dry mix and pass on a resulting signal to a ratio-controller which in turn controls a main water spray to deliver water to the mix in the necessary ratio to give the required moisture content. Specification 858,736 is referred to.

An electrode for a high-pressure mercury vapour halogen discharge lamp includes a metal outer part which is in electrically and thermally conducting relationship with a current supply wire, which surrounds a space at least half of which is occupied by an emitter body, and which has an opening at the side remote from the current supply wire so that the end of the discharge can rest on the emitter body during the starting condition, the emitter body being connected to the current supply wire by a path which includes the metal outer part and which has a thermal resistance such that during the cooling period following the extinction of the lamp the emitter body remains at a higher temperature than the metal outer part, whereby condensation of halogenide upon the emitter surface is prevented. The emitter body 14, Fig. 2, which preferably includes an immersed tungsten helix 13, is supported within an outer tungsten helix 11 with which it makes poor thermal contact, the outer helix being connected to the current supply wire 10. In another embodiment (Fig. 3, not shown) the turns of the outer helix do not contact the emitter body, but the free end portion of the helix wire is bent back along the helix axis, and supports the emitter body, thermal conduction to the current lead being reduced by the length of the therma path.

Abstract: 1477933 Transistor inverters INTERNATIONAL COMPUTERS Ltd 19 Sept 1975 [21 Sept 1974] 41199/74 Heading H2F [Also in Division H3] To stabilize partition of switched current pulses between collector-emitter paths of a plurality of transistors, e.g. TR1-TR4, connected in parallel in a pulse switching circuit driven by a pulse source 12 feeding the bases, the collector-emitter paths are interconnected by transformers to increase the impedance to any out of balance current with simultaneous inducement of increased current through any path connected to the other winding. For equal current storing all transformers have 1 : 1 ratio; for non-uniform partition, ratios may be adjusted accordingly. For two transistors only one transformer is used, but for more than two transistors cyclic connection as T1-T4 allows a loss of current through one transistor to be compensated by all the remainder. Diodes D1-D4 assist turn off at the end of each pulse fed through base resistors R1-R4. Application of two such switching circuits to a push-pull inverter is possible used for example in a computer power supply.

The spring acting on the movable body may be a bent spring which is bent in a plane extending parallel to the longitudinal direction of the support or the longitudinal force may be supplied by the striker springs. As shown in Figs. 1 and 2 the body 15 is moved by leaf-spring 22 in a step-wise movement achieved by escapement 27, actuated by stabbing action of member 29 on the camera. At each step a projection e.g. 17 with an inclined rising edge lifts an end portion of the spring over a locking-pin e.g. 6 causing it to strike the stem 4 of the flash-bulb. In another embodiment the force required for moving the bodies is supplied by the striker springs. During the first stepwise movement spring 46 Fig. 5 is unlocked by being lifted over projection 60 by ramp 65 and fires flash-bulb 42. In Fig. 7 the striker springs 80, 81 and 82 exert a longitudinal force on the body 76 by stepwise movement of which they are sequentially unlocked. Stepwise movement can be controlled by an escapement.
