Title: Electromagnetic apparatus for moving a rod
IPC: G21C7/12
Filed: 1956-10-01
Abstract: 806,845. Electromagnets. YOUNG, J. N. Oct. 1, 1956 [Nov. 22, 1955], No. 29836/56. Class 35. [Also in Group XL (a)] A rod 20, such as a control rod for a nuclear reactor, is moved step-by-step by energizing in turn two magnetizable gripping units. Normally coils 40, 41, 42, 43 are energized, and to move the rod 20 to the left firstly the coils 42 and 43 are de-energized. This causes a soft iron collar 31 to move to the right, attracted by a similar collar 25 with winding 41, so that balls 28 reach the end of a conical recess 27 and thereby release fingers 24 forming part of a collar 30 and gripping the rod 20. Next the winding 42 is energized to pull the collar 30 along to the collar 31, so that the fingers 24 therein take a fresh grip on the rod. Now, by de-energizing 41 and re-energizing 43 the gripping unit 30, 31 is moved to the left by the attraction of a soft iron stop 36, taking the rod 20 with it and free from the grip of 25, 23. Re-energizing 41 completes the cycle, moving 25 to the right and causing 25, 23 to take a fresh grip. The gripper units may take other forms, such as assemblages (Fig. 10) each having four loose bars 121 with two spaced projections 123 encircling the rod 20, so that energizing a set of coils 134, 135, 136, 137 causes the bars to move radially outward and grip the rod. Suitable energizing of the " gripping " coils, a centre coil 138 and end coils 143, 133 will then move the rod to left or right and this arrangement allows stepwise movement of the rod 20, even if it is vertical. Other gripper units described use rollers in place of balls with springs that enforce separation of unmagnetized units, or comprise members that flex. In all cases the gripper units are enclosed in a housing sealed at one end 35a to the pressure vessel of the reactor and capped at the other end to retain the pressure. At the capped end a further device, with a housing sealed to the gripper housing at 50, may be employed to return the rod to the reactor rapidly for shut-off purposes. This further device comprises a gripper unit 55 urged by a spring 56 to shut-off position but normally held by an energized coil 67 so that it does not grip the rod and the latter may be moved stepwise quite freely.

Abstract: 1521198 Automatic control of speed TOYOTA JIDOSHA KOGYO KK 21 July 1976 [2 April 1976] 30311/76 Heading G3R In a vehicle speed control system, a vehicle speed dependent voltage is compared with upper and lower limits, to generate an "off" signal if greater than the upper limit and an "on" signal is less than the lower limit. In response to an "on" signal, a throttle valve is opened and, using an electromagnetic relay, a connection made between a vehicle battery and ignition coil, this connection not being made for an "off" signal. As shown, the speed dependent voltage from tachometer 40 is fed to comparator 90 to be compared with an upper limit set by resistors Ro, R 1 , R2 or a lower limit set by R 0  and R 1 . In the latter case, R 2  is shorted by transistor Tr 2  whenever the actual speed exceeds the upper limit, using the inverted comparator output. The output of the comparator forms the "on" or "off" signals which control a switching transistor Tr 1  in series with the electromagnetic relay 42. The throttle valve is opened in, response to the energization of relay 42, provided the vehicle accelerator is pressed and provided the engine is not in neutral or low gear, or the clutch not connected. Thus the acceleration or deceleration of the engine is controlled so as to keep its speed between the upper and lower limits. In an alternative, Fig. 1 (not shown), the upper and lower limits are independently set and each compared with the actual motor speed signals, to control a flip-flop circuit connected to the transistor Tr 1 . Details of the engine starting circuit and ignition circuit are also given on that figure.

Abstract: 409,360. Impedance networks. RYALL, L. E., 52, Crescent Gardens, Eastcote, Ruislip, Middlesex. Oct. 31, 1932, Nos. 30506/32, 34722/32, and 3/33. [Classes 40 (iii) and 40 (v).] Distortion of signals is neutralized by means of a network containing dry-plate rectifiers located in an A.C. circuit and adapted to produce distortion equal and opposite to that from which the signals suffer. Thus a triode amplifier, in which output is related to input as the ordinates to the abscissµ in Fig. 1 (3/33), may be corrected so as to produce a linear overall characteristic by the insertion in its input or output circuit of a network comprising a rectifier and resistances, as shown in Figs. 4 and 5 (3/33). The rectifiers 1 and 3 may be replaced by pairs of oppositely directed rectifiers connected in parallel with one another if a pentode valve is to be corrected, Figs. 2, 6, 7 ( 3 /33 ) (not shown), or in series with one another if a push-pull pair of valves is to be corrected, Figs. 3, 8, 9 (3 /33) (not shown). The compensating network is preferably connected at a point in the system where the effect of the system on phase-change is the same for all frequencies ; alternatively one of the resistances shown may be shunted by a condenser to compensate for unequal changes of phase. To produce unequal distortion in positive and negative half-cycles, a further resistance may be connected in series or parallel with one member of a pair of rectifiers. In a telephone repeater used for amplifying two or more speech channels simultaneously (e.g. one comprising frequencies from 300 to 2500 and the other from 3000 to 5500) the corrector circuit 8, 9, is included in the output transformers to compensate for any distortion introduced by the second valve 5. Gain is controlled by means either of tappings on a potentiometer 4, or of tappings on a transformer 2 in combination with a condenser 6 which gives increased gain at high frequencies. Since distortion introduced by the first valve 3 cannot be compensated by the network 8, 9, such distortion is reduced by the use of a large anode impedance 10 ; and a grid condenser 12 may be used to compensate for distortion due to internal capacity of the second valve 5. Phase-distortion due to leakage inductance in the transformer 13 is compensated by means of a high-impedance choke 14 in the anode circuit of valve 5 ; and to compensate for loss of gain at low frequencies the anode resistance 10 of the first valve 3 may be shunted by a resistance and condenser 16, 17.

Abstract: 628,752. Magnetrons. M-O VALVE CO., Ltd., and BALLS, A. W. Nov. 7, 1947, No. 30555/46. [Class 39 (i)] In a magnetron in which the anode comprises a toroidal resonator 1, Fig. 1, the inner wall 3 of which is perforated by a slot to opposite walls of which are fixed interdigitated fingers 5 forming the anode segments proper, the lengths of the fingers are so small compared with the circumferential distance round the wall of the resonator from one side of the slot to the other that the operating frequency is substantially independent of the lengths of the fingers. As a result, the various possible modes of oscillation are more widely separated. The resonator walls may be thin, or alternatively the resonator may be formed in a solid block, in which case the block may be formed in two halves which are fitted together along a plane at right angles to the longitudinal axis of the toroid. The anode fingers may be formed integral with the material of the half-blocks or separate fingers may be welded or screwed thereto. The fingers need not be rectangular, they may be of appreciable radial thickness and of triangular cross-section. The resonator is tuned by a screw plug 9 and energy is extracted by a coupling loop projecting through hole 7, or by an opening from the resonator into a waveguide, or by means of a connection to one of the anode fingers. The resonator may have a rectangular, circular, or part-rectangular and part-circular, cross-section, the section being taken in a plane containing the longitudinal axis of the toroid. Prior art magnetron arrangements in which an anode block defines a plurality of resonators which may be coupled to a common annular surrounding channel, and in which alternate anode segments may be strapped, are referred to and it is stated that such arrangements are difficult to tune over an appreciable frequency range since each cavity must be individually tuned. Specification 574,551 is referred to.
