Title: Improvements Relating to Tension Indicating Bolts
IPC: F16B31/02
Filed: 1980-06-24
Abstract: A tension-indicating bolt 10 has an axial bore 12 in which a plug 13 is fixed. A pin 17 is received in the bore 12 and passes through a bore in the plug 13. The plug is stuck in place with its inner end abutting a stop 33 and holding the end of the pin bottomed in the bore when the bolt is un-tensioned. The tension in the tightened bolt 10 is indicated by the relative positions of the outer end surface 22 of the pin and an adjacent surface 21 of the plug. The relative positions of the two surfaces 21 and 22 can be indicated with any suitable gauge. To facilitate the application of a gauge, the plug 13 has an externally screw threaded head 14. A method of fitting the plug 13 using adhesive to avoid exerting pressure on the pin 17 is described. In a modified embodiment the pin is held bottomed by a compression spring acting between the plug and a stop on the pin; Fig. 3 (not shown). <IMAGE>

Title: Electronic timepiece with stepping motor
IPC: H02P8/02
Filed: 1980-08-29
Abstract: An electronic timepiece comprises a stepping motor driven by alternating square wave pulses, and a detector circuit for detecting the non-rotation condition of the rotor. The detector circuit is responsive to motor load current and looks for the presence of points A, B or C in the load current waveform curve 3 Fig. 1 which indicates normal rotatable condition. If the rotor has missed a step or the load is excessive such that these points are not detected, the load current being as waveforms curves 1, 2 Fig. 1, the detector circuit output is used to progressively adjust drive pulse duration accordingly as in Fig. 7 arrangement, or to make up for lost steps as in Fig. 6 arrangement. The detector circuit comprises an amplifier 24 including MOS transistors 1, 2 (eg as in Fig. 2) and a capacitor 3. Voltage applied to the amplifier is proportional to and has the same waveform as the motor drive current. <IMAGE>

Patent GB-2116587-A (GB)
Title: Production of carbon electrodes for electrolytic reduction cells
Inventor: HOLDNER DONALD NORMAN
IPC: C25C7/02
Filed: 1982-03-16
Abstract: In the production of carbon electrodes by baking compacted green shapes formed of calcined carbon aggregate and pitch, and pitch content of the green shapes is controlled to produce baked products of optimum electrical and mechanical properties, the quantity of the pitch blended with the aggregate is related to the quinoline-insoluble fraction of the pitch and the void space in the unbaked green shape occupied by the binder. The production is controlled by establishing a target density for the formed green blocks in accordance with the quinoline-insoluble fraction of the pitch and its softening point and density, together with the value of the real density of the carbon aggregate and the proportion of the carbon void space to be filled by binder for a green block of optimum binder content. The actual density of the green block is compared with the target value and conditions are adjusted when there is excessive divergence of the actual value from the target value.
