IPC: G21C19/02
Filed: 1963-01-02
Abstract: 963,961. Fuelling reactors. COMMUNAUTE EUROPEENNE DE L'ENERGIE ATOMIQUE (EURATOM). Jan. 2, 1963 [Jan. 23, 1962], No. 294/63. Heading G6C. [Also in Division B8] A manipulator arm for inserting fuel elements or samples into a reactor core comprises two similar chain-like assemblies one assembly having inter-pivoted link members 1a, 1b 1c &c. and the other assembly having link members 2a, 2b, 2c &c. Adjacent members of each assembly are interconnected by pivot assemblies A; also, each member of either chain (e.g. member la) is adapted to be releasably coupled with both adjacent link members of the other chain (e.g. members 2a and 2b) by an automatically releasable coupling device B. The link members are shell-like and when the two chains are coupled together as in Fig. 1 they form a rigid tubular arm to the end of which tools may be connected. Each link member has outwardly extending side flanges 3 provided with a cut-out 4 and the front end of each flange, having regard to the direction of motion F of the chain, has fixed thereto a bearing ring 9 forming part of the assembly A. The rings 9 of each link member are journalled on shafts 6 extending laterally from the rear end of the preceding link member, the shafts also carrying rollers 12 co-operating with guide rails (not shown). Each coupling device B comprises a two-armed lever 15 pivotally mounted for adjustment about a pivot 16 at the front end of each side flange 3 of each of the link members. Each lever is clamped in its adjusted position by nuts 18, 19 co-operating with a threaded shank 17 connected at 20 to the rear arm of the lever and with the flange 3 on which the lever is mounted, the forward arm 24 of the lever engaging the outer surface of a flange 3 of a link member appertaining to the opposite chain. Thus, as shown in Fig. 1, arm 24 of the lever 15 mounted at the front end of link member 2b engages a flange 3 of link member 1a, and the flange 3 of member 2b together with flange 3 of the preceding link member 2a are held against the flange 3 of the link member 1a of the opposite chain to form a rigid assembly. Lateral displacement between the two chains is prevented by rods 22 on one chain co-operating with grooves 21 in the other. In use, the two chains when in idle condition are wound in separate coil drums and these coils are rotated in opposite directions to bring the chains together to form a rigid arm as in Fig. 3, the chains meeting one another tangentially such that the levers 15 of one chain enter the cut-outs 4 of the other chain and engage the flanges 3 of the other chain. Specification 963,962 is referred to.

Title: Quartz crystal timepiece
IPC: G04G3/02
Filed: 1976-01-09
Abstract: 1518221 Electronic timepieces SUWA SEIKOSHA KK 9 Jan 1976 [13 Jan 1975]  00816/76 Heading G3T [Also in Divisions G4 and H1] An electronic timepiece includes an oscillator circuit controlled by a quartz crystal arranged to oscillate in the thickness shear mode at a resonance frequency of between 1 MHz and 10 MHz. Data stored in a memory circuit is periodically transmitted into a frequency dividing circuit to adjust the running rate of the timepiece. In Fig.3, an oscillator circuit 11 includes a thickness-shear quartz crystal vibrator 9, detailed in Fig. 4. From the oscillator circuit output a pre-settable down-counting frequency divider chain 21 of "n" flip-flops produces a signal f', at 1 Hz which is fed to a divider circuit 13 comprising secs, mins, hours, date &c. counters. The respective timing signals from circuit 13 are applied to a driving circuit 14 to drive a display device 15 e.g. comprising liquid crystal or LED elements. The running rate is continuously regulated by a memory circuit 25. Thus if the oscillator output frequency is below 2<SP>n</SP> Hz so that the period of the divider 21 output signal f' 1  is (1 + #t) secs, whereas it should be 1 sec, a binary code which is decreased  by the equivalent of #t secs is written into the memory circuit 25. For every pulse from oscillator 11 one unit is subtracted from the content of the down-counting divider 21 until the divider content becomes (000 ----). At this instant an output pulse is produced by the divider and consequently a pulse f p  is produced by a pulse generator 24. The pulse f p  opens the gate circuits 23 so that the data written into the memory is transferred to divider 21 and the cycle is repeated. Thereby the divider output frequency is adjusted to be exactly 1 Hz. For example if the period of the divider output is longer by the equivalent of two pulses of the oscillator signal f o ', data (1, 0, 1, --- 1) is written into the memory 25. Use is made of the divider circuit 13 and the time indication correction circuit 22 to write data into the memory 25. As illustrated Fig. 6 (not shown), the divider 13 and memory 25 have the same number of stages which are inter-connected respectively. Data is first written into divider 13 and displayed by operation of the correction circuit; this data is transferred to the memory to pre-set it, upon application of a timing signal f m .
