Title: A device for mechanically selecting nuclear reactor measuring channel pipes
IPC: G21C17/108
Filed: 1971-05-20
Abstract: 1300357 Reactors LICENTIA PATENTVERWALTUNGS GmbH 20 May 1971 [22 May 1970] 16085/71 Heading G6C In a device for mechanically selecting one of a number of measuring channel pipes disposed inside a nuclear reactor for the purpose of introducing a measuring probe, e.g. for measuring neutron flux, the measuring channel pipe connections are brought together and arranged on a circle around the centre of which a curved selecting pipe is rotatable. As shown, the device consists of a casing 1 on one end face 8 of which the measuring channel pipe connections 11 are arranged in boreholes. A plate 6 rotatably mounted inside the casing on a shaft 4 has a borehole 12 for receiving a selecting pipe 3 through which a measuring probe 2 may be moved. Seals 9 are provided between the plate 6 and the end face 8, the plate 6 being pressed against the end face 8 by means of a spring system 7 in the opposite end face of the casing 1. The seals 9 are preferably sealing rings mounted in corresponding grooves in the casing and arranged concentrically round the measuring channel pipe connection ends inside the casing. They ensure that the measuring channel pipes which are not selected are sealed off. The selecting pipe 3 passes out of the casing through the centre of the shaft 4. The shaft 4 is driven by a worm gear 5. In the case of a water-cooled reactor, spark plugs 10 are mounted on the end face 8 adjacent each of the pipe connections 11 to which they are connected by cross-boreholes. Should water penetrate into the measuring channel pipes, the electrodes on the spark plugs 10 short-circuit and an indication of this is given externally. A spark plug 10 is also mounted on the opposite end base of the casing 1, its purpose being to determine bigger leaks which occur while the probe is travelling along the selected measuring channel pipe.

Title: Improvements in or relating to operation control devices
IPC: G09F11/00
Filed: 1953-06-12
Abstract: 767,946. Calculating - apparatus. BRUNSVIGA MASCHINENWERKE AKT.-GES. June 12, 1953 [June 14, 1952], No. 16289/53. Class 106 (1). [Also in Group XXIV] A shaft for controlling operations of a machine, such as a calculating machine, is advanced by a pawl which engages a ratchet wheel mounted on the shaft and having at least one oversize tooth or a gap between teeth. which renders the pawl ineffective until the shaft is advanced slightly by other control means. On depression of a key 10, a motor switch 16 is closed and a pawl 12 pivoted on the key engages and partially rotates a ratchet wheel 6. A locking element 9 on the wheel engages over a lug 13 of the key to maintain it in depressed position. The wheel is formed with groups of three teeth separated by gaps 8, one of which is normally located adjacent to a pawl 4 operated by an eccentric on the motor shaft. The partial rotation of the wheel enables the pawl to engage the next tooth and consequently the wheel is advanced three steps during three rotations of the motor shaft. During these rotations, a cam connected to the wheel engages a clutch between the motor and gearing of ratio 3: 1 by which the mainshaft is rotated one revolution. After the three steps of the wheel, the key 10 is released and the motor switch opened. In a modification, the wheel has a single group of teeth and one enlarged tooth by which the pawl is rendered ineffective. Restoration of the key is aided by a cam on the wheel. A repeating device for multiplication includes nine keys 20, Fig. 3, which co-operate with a detent bar 29 associated with the motor switch 16. Depression of a key differentially positions a slide 24 having cam-surfaces 22 co-operating with pins in the keys. A pawl 28 carried by the slide 24 engages a pin 28<SP>1</SP> in a ratchet wheel 61 to advance the wheel a number of steps representing the complement of the number of the key. The wheel has groups of ten teeth so that when the motor switch is closed after this initial setting of the wheel, a pawl 4 driven by the motor shaft advances the wheel a number of steps determined by the key which was depressed. A pin 32 in the wheel then engages a projection 31 of the bar 29 to free the depressed key and open the motor switch. In a machine for performing automatic division, during a series of repeated subtractions, a ratchet wheel 6<SP>111</SP>, Fig. 4, is positioned so that an enlarged tooth 8<SP>111</SP> is engaged ineffectively by a pawl 4<SP>11</SP> driven by the motor shaft. When the dividend becomes negative, a cam 40 rocks a lever 42 carrying an arm 37 held depressed by a control key 10<SP>1</SP>. A pawl 39 on the arm 37 thus slightly advances the wheel 6<SP>111</SP> to enable the pawl 4<SP>11</SP> to advance it further by three steps during which an addition operation takes place, the totalizer carriage is column-shifted, and the machine is re-set for subtraction.

Filed: 1959-05-12
Abstract: 866,632. Pulse synchronization systems. COLLINS RADIO CO. May 12, 1959 [Sept. 23, 1958], No. 16294/59. Class 40(5) . In an arrangement for synchronizing gating pulses 1, generated in a receiver, with discrete phase changes in received pulses of tones, successive pulses are applied to resonators 1, 2, Fig. 1, of the type described in Specification 828,781 wherein the oscillation of the resonator in response to a pulse without phase shift increases to a maximum and falls away to zero at the end of a pulse, and the amplitudes of the electrical outputs through sampling gates 21, 22 are dependent upon the position in the pulses at which the phase changes occur. The tone pulses applied to the resonators by gates 11, 12 overlap in the manner of pulses 72, 73, Fig. 4, and ideally the phase change 91 occurs in the centre of the overlap 70. In this condition the electrical outputs M, O, through the gates 21, 22 are equal and there is no output from an amplitude comparator 26 to which they are applied. If however the timing of the gating pulses is such that the phase changes are not in the centre of the overlap, outputs 19, 15, sampled from the resonator, produce from the integrated comparator output an out-of-synchronism error signal which, when applied to a servomotor 29, effects a phase shift of the input from reference timing source 31 to receiver time-base generator 33. The development of square wave controlling pulses from a sine wave input by single shot multivibrators differentiating circuits and flip-flop arrangements is described. Specification 828,782 also is referred to.

In a multiple expanding V-belt spring pulley, two groups of frusto-conical flanges 12, 14, 16 and 13, 15, 17 are rigidly connected together by arcuate fingers 31, 35 and 30, 34 through which are passed tie-bolts 40, 41, the fingers being integral with their respective pulley flanges 14, 16 and 13, 15. The fingers interengage with each other and pass through slots such as 32, 33 in the pulley flanges. Axially directed keys 4, 5, fast in a rotatable sleeve power transmitting member 1, are engaged by the fingers, the arrangement being such that the two groups of pulley-flanges 12, 14, 16 and 13, 15, 17 are axially slidable but non-rotatable with respect to each other and with respect to the rotatable sleeve. Spiral compression springs 47, 48 between the flanges urge them together and are received in recesses such as 46, each of these recesses being equal in depth to at least half the minimum length of the springs. The pulley is centred for axial movement on the sleeve 1 by stops consisting of the ends of the keys 4, 5 engaged by the flanges 12, 17 and by screws 7, 8. In one modification, Fig. 3 (not shown), each spiral spring 47, 48, is replaced by a plurality of helical springs. In further modifications, Figs. 4, 5 (not shown), springs are alternatively or additionally mounted around arcuate fingers extending beyond the end pulley flanges 12, 17.

The 14-hydroxy-#<SP>4,6</SP> compounds I are prepared from or via compounds of formulµ (wherein Z is CHO or CO 2 H) as follows: Oxidation of II (e.g. with CrO 3 /H 2 SO 4 ) yields I (14α-OH; R<SP>1</SP>=oxo; major produet)+ I (14#-OH; R<SP>1</SP>=oxo)+III (Z=CHO)+III (Z = CO 2 H). Epoxidation of II (e.g. a peracid) yields V (major product) + the 8α,14α-isomer of V, both of which are convertible into 19-acetates (Examples 10, 11). Oxidation of V yields VI acidification of which yields I (14#-OH; R<SP>1</SP> = OH)+ in Example 12 some 14α-isomer.
