Title: Apparatus and method for accurate measuring of d.c. voltage and resistance values bycomparison
Inventor: PARNUM DERRICK HENRY
IPC: G01R1/28
Filed: 1951-01-23
Abstract: 696,837. Voltage and resistance measurements; bridge circuits. PYE & CO., Ltd., W. G. Jan. 16, 1952 [Jan. 23, 1951], No. 1743/51. Class 37. For comparing two D.C. voltages e1, e2, Fig. 3, which are known to be approximately equal, each voltage is applied in turn to an A.C. detector circuit D through a changeover switch S operated at constant changeover frequency, so that any difference between the voltages is applied to the detector d as an A.C. voltage. When the two D.C. voltages e1, e2 are equal the detector gives zero response. The switch S has a short open-circuit period so that the voltages e1, e2 are never connected to the same points at the same time. The switch S may be a motor-driven commutator, cam-driven contacts, or vibratory interrupted contacts, the frequency of operation preferably being over 5 cycles per second. The detector D may comprise a valve amplifier and a rectifier which may be polarized by a frequency equal to that of the changeover switch, so as to be phase sensitive. Part of its D.C. output may be applied to the input circuit to provide negative feed-back and thereby provide a linear relationship between the output and input and give an accurate indication of the difference between the voltages e1, e2. The voltages e1, e2 may be applied to the detector through a condenser to eliminate errors due to the internal resistance of the sources of voltages e1, e2. Two resistances, for example low resistances having current and potential terminals, may be compared by connecting them in series and comparing the voltages across their potential terminals by the method described. A bridge circuit as shown in Fig. 5 may be employed, where the unknown resistor R1 and standard resistor R2 form two arms of the bridge and are both four-terminal resistors. The other two arms are formed by a fixed standard resistor R3 and a variable standard resistor R4, both of which are twoterminal resistors of comparatively high value. The voltages e1, e2 across the resistances R1, R2 are compared and R4 is adjusted until balance is obtained.

Abstract: 833,831. Handling radioactive materials. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 20, 1958 [Jan. 21, 1957], No. 1893/58. Class 39(4). [Also in Group XXX] An arrangement for inserting vessels 7 containing irradiated material in sockets 6 arranged in parallel rows in the floor 5 of a fluid-tight storage chamber 1, comprises a gantry 10 movable along runways 8 on the chamber side walls 3 and itself having runways 18 for the traversing movements of a hoist-carriage 20, the gantry 10 being driven by power means 15 situated on the chamber roof 4, the drive being transmitted through vertical shafts 14, gearing, and chains secured to the ends of the gantry, Fig. 1 (not shown). A drive shaft 74 is mounted in the roof 4 above each socket 6 and each shaft may be driven by either one of two power units 76, 77 displaceable on the roof, unit 76 serving to traverse the carriage 20 and unit 77 serving to operate the carriage hoist mechanism. The carriage 20 carries a ratchet, Fig. 2 (not shown), whereby it may be traversed by any one of a number of pinions 22 mounted at intervals along the gantry 10 on vertical spindles 24, the shafts 24 being driven through gearing 26 and shafts 27, 28 from a vertical shaft 30 and gearing 29. The upper end of the shaft 30 has a fork joint 31 which may be engaged by a shaft 74 when the latter is lowered whereby the drive is transmitted from the unit 76 to the carriage. The carriage 20 supports a casing 32 by means of two sets of recilinear rolling tracks 33, 34, whereby the casing may move in the carriage for limited distances in two directions mutually at right angles for the purpose of exactly centring the hoist over a socket 6. A sleeve 36 suspended by a ball joint 37 from a bar 40 secured at its ends to hoist chains 41, has pivotted thereto about axes 54 three 120 degree displaced levers 53 having hooks 55 at their lower ends. The hooks are simultaneously moved outwardly to engage under a flange 56 of a vessel 7 by rotation of disc 58 having cam slots, Fig. 6 (not shown), in which the upper ends 60 of the levers 53 engage. The chains 41 are driven to lower or raise the sleeve 36 through gearing, Figs. 8, 9 (not shown), situated in the top 35 of the casing 32, further gearing serving to rotate the disc 58 through a splined shaft 62 driving a pinion 61 meshing with the toothed edge of the disc. By coupling the unit 77 to the appropriate shaft 74 and by lowering shaft in three successive steps, the shaft makes driving engagement with various coupling means in the casing top 35 such that firstly, the hoist is centred, Figs. 10, 11 (not shown) ; secondly, the hoist chains 41 are operated ; and, thirdly, the hooks 55 are operated. Mechanical interlocks ensure that these operations take place in the correct sequence, Figs. 12-14 (not shown). The insertion of a vessel 7 in a socket 6 may open a valve to cause coolant air to enter the chamber 1 through channels 106. . . 108.

Title: Means for automatically controlling an electrically driven winding gear
IPC: H02P7/06
Filed: 1942-02-13
Abstract: 554,518. Automatic control systems for electric winding gear. ENGLISH ELECTRIC CO., Ltd., DOLAN, H., and AYRES, W. E. M. Feb. 13, 1942, No. 1947. [Class 38 (iv)] Speed.-Where a speed controller for an A.C. motor operating winding gear is responsive to the difference between a predetermined speed (which may be represented by an EMF or frequency) and the speed of winding, braking of the motor by supplying D.C. to its primary windings occurs when the speed controller is driven back past its neutral position. The speed controller may, for example, be actuated directly by a D.C. servomotor or through a relay subject to the difference between the EMF or frequency of a generator driven by the winding gear and an EMF or frequency predetermined by a master controller, or may be actuated mechanically from a differential gear connected between the winding motor and a motor controlled in speed by a master controller Fig. 1 shows a master controller 10a determining the direction of wind by actuating a selector switch 13 and the speed of wind by operating a potentiometer contact 10 varying the excitation of a constant speed generator 6 without changing its polarity and adapted also to reverse the excitation of a generator 3 driven by the winding motor 2 to maintain a polarity in' opposition to that of the generator 6. The motor 4 operates the speed controller 5 in one direction from its neutral position when the winding speed is lower than the predetermined speed and returns it in the opposite condition. The movement of the speed controller at starting actuates a switch 14 to close the circuit selected by the switch 13 to energize a direction contactor 15, 16 to put A.C. on the winding motor 2. If during deceleration. the braking due to the resistance inserted by the speed controller 5 into the secondary circuit of the motor 2 is not sufficient the controller 5 will pass its neutral position and actuate the switch 14 to cause the A.C. to be cut off from that motor and D.C. to be applied by the braking contactor 17, and will at the same time progressively reduce the resistance in the secondary circuit. In a modification, Fig. 2, the master controller is arranged to reverse the polarity of generator 6, generator 3 reversing with change in winding direction, which is effected by a change-over switch co-operating with a similar switch actuated by the speed controller to energize selectively direction contactors. A second pair of switches operated likewise controls the braking contactor. Interlock 19 is opened when the mechanical brake is applied. Certain subjectmatter described in Specifications 509,261, 517,223, [both in Group XXXVII], 517,468; 518,476, 531,310, [both in Group XXXVII], and 553,434, may be incorporated with the invention.

Filed: 1934-01-19
Abstract: 432,201. Projectiles. NEVITT, J. B., Cottesloe, Featherston Road, Streetly, EWINS, G., 54, Britwell Road, Wylde Green, both near Birmingham, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Jan. 19, 1934, Nos. 2007 and 4331. [Class 9 (i)] Relates to explosive, incendiary, and tracer projectiles having a slow burning time fuze ignited on discharge. According to the invention the time-fuze composition is housed within a compartment separate from the main charge and is so correlated with the partition between it and the main charge that fusion or disruption of the partition does not occur as a direct result of the ignition of the fuze composition, the detonation or melting or ignition of the main charge being effected solely by the heat conducted through the partition. In the projectile shown in Fig. 1, a primer 4 is ignited by the flash of the propellent at the moment of discharge and fires a tracer 3, which also acts as a time fuze. This tracer is in a copper thimble 2 having a recess 7 at its closed end containing a primer 8, covered by a thin lead foil, opposite a passage 11 in line with the cavity 16 in the main explosive charge 9. The inner end, of the thimble 2 is lined with insulation 14 and at the appointed time gets sufficiently hot to ignite the primer 8, which fires the main charge 9, if this has not previously been fired by a percussion fuze 12, 13. In the projectile shown in Fig. 2, a similar time fuze 17, not a tracer, fires a heating charge 26 of blackpowder and carnauba wax for melting a tracer charge of yellow phosphorus 29 in a sealed container provided with a hole 33 in line with an outlet 34, both normally sealed with solder. In another form, the heater 26 is dispensed with, and the container of the time fuze arranged to project into the phosphorus charge. Specifications 127,271 and 127,272, [both in Class 9 (i)], are referred to.

Abstract: 647,843. Electromagnetic relays. WESTERN ELECTRIC CO., Inc. Jan. 23, 1948, No. 2126. Convention date, Feb. 24, 1947. [Class 38(v)] A relay with a slow action has a core 10 carrying an operating winding 1 and shortcircuited coils 14 and an amature in the form of a frame with cross pieces at 64, 48 and 42 is pivoted at 64 so that air gaps pulling the armature in opposite directions are provided between the core and the cross pieces at points 53 and 43 lying on opposite sides of the core. The hinge at 64 includes a separating layer of non-magnetic material which may take the form of washers. The cross piece 42 is bent as shown in Fig. 3 and carries a member 58 which operates the studs 63 which operate the two sets of contact springs arranged on the two sides of the relay. Fig. 2 shows the relay operated. On de-energization a spring 54 helped by the contact springs returns the armature quickly to its other position, Fig. 3. On re-energizing the winding 1 the flux traversing the core and armature consists of a permanent steady flux due to the winding and a transient ever diminishing flux due to the induced currents in the short-circuited coils 14. The latter flux opposes the former, the net result being that to start with nearly all the flux from the magnet 1 passes over the air gap 53, now at its smallest, and none passes through the hinges 64. The attraction at the air gap 53 thus overpowers the attraction at the gap 43, now at its largest. As the transient flux diminishes flux passes more and more through the hinge 64 and less through the gap 53 so that eventually the flux at the gap 43 overpowers the flux at the gap 53 and the relay operates: Adjustment for different times of delay is effected by adjustment of the air gap 53 and by adjustment of a disc 20 of magnetic material which serves to divert some of the flux from the air gap between 10 and 43.
