Filed: 1970-09-28
Abstract: 1318969 Battery intercell connectors CHLORIDE BATTERIES AUSTRALIA Ltd 28 Sept 1970 [2 Oct 1969 5 Dec 1969] 46049/70 Headings B3R R2K R14 R2F and R6  An intercell connecting arrangement for connecting plate electrodes of one polarity of one cell to the plate electrodes of opposite polarity of an adjoining cell of a multi-cell battery, the cells being separated from each other by thin walls of an injection-moulded thermoplastic material, includes preforming the aperture 16, Fig. 2, in the cell wall 17 through which the intercell connector passes so that the material surrounding the aperture extends above the plane surface of the wall and is received in a recess 15 in the intercell connector, Fig. 4. The intercell connector comprises two parts 7, 8, Fig. 4, related respectively to two adjoining cells, the horizontal arms 9 being connected to the plate electrodes Figs. 1, 6, (not shown). Part 7 has the annular recess 15 surrounding a protuberance 20 and part 8 has a protuberance 19. Heat and pressure are applied to the parts 7, 8 to cause melting of the material of the protuberances 19, 20 so that the parts are welded together, Fig. 5. During this process the material of the wall 17 trapped within the connector is deformed to ensure a seal against electrolyte leakage between the cells. Pressure may also be applied to the connector after the welding operation of connecting arrangements before the application of heat and pressure are shown in Figs. 7, 11, 13, 15.

Title: Digital System For Controlling A Seismic Transducer
IPC: G01V1/02
Filed: 1967-10-10
Abstract: 1,153,975. Data storage arrangements. CONTINENTAL OIL CO. 10 Oct., 1967 [16 Nov. 1966], No. 46223/67. Heading G4C. [Also in Divisions G3 and H4] To eliminate equipment-induced timing errors in a waveform control signal for a seismic vibrator the signal, comprising a sequence of digital " words ", is placed in a buffer store and successive words are then read out from the store at a precisely controlled rate for application to a digital-to-analogue (D/A) converter and thence to the vibrator. In the Fig. 3 embodiment the control signal is computer-generated or derived from an analogue waveform by an analogue-to-digital converter and comprises digital samples (of a frequency sweep signal) in the form of sequentially recorded words, each word being two sequential " characters " of seven " bits " each, on magnetic tape 112. The seven bits are read in parallel by head 114 and applied to OR gate 120 to provide one clock pulse per character for driving shift register 124. These clock pulses, taken from one output of the shift register, are fed also to phase comparator 106 to provide an error signal for phase-locking the playback speed of tape 112 to a precision oscillator 90. Sequential outputs on lines 150-168 of register 124 open respective gates 130-148 to steer successive characters from playback amplifier 126 to an N-word buffer store 190-200 (e.g. comprising bi-stable circuits). The words are read out from the store by opening gates 212- 220 sequentially with pulses provided by shift register 222 at a precise rate controlled by oscillator 90. The readout rate is thus unaffected by wow and flutter in the tape playback process. The words from gates 212-220 are reconstituted as an analogue signal by D/A converter 98 and applied directly, or via a radio link 254, to the vibrator 18. This analogue signal may also be used in subsequent signal processing (e.g. correlation) of the output of a geophone array. As soon as a particular word has been read out from store the associated storage element is reset by an output from reset shift register 238 so that the storage element is freed for storing a further word from tape 112. If tape or other speed errors are large or have a long term drift a large buffer store is required and the store may then comprise magnetic cores or may be a random-access store of sufficient capacity to store the total digital sweep signal (in which case the tape record 112 is unnecessary). Details of the application of the individual data bits to the gates 130-148 and store 190- 200 are given (Fig. 4, not shown).

Abstract: 1454366 Measuring instrument with cut-out AVO Ltd 24 Oct 1973 [24 Oct 1972] 48992/72 Heading H1N A measuring instrument with an armature 51 has an overload cut-out comprising a pair of contacts 13, 15 held engaged by a latching mechanism including a first pivoted lever 37 moved by excessive movement of the armature 51 and a second pivoted lever 33 biased in the latched condition into engagement with the first lever with the engaging portions of the two levers 35, 42 engaged in a condition of stable equilibrium. The extremity 42 of projection 41 on lever 37 is straight and at right angles to the radius from pivot 38 to pin 35 so that a slight rotation of lever 37 pushes pin 35 away from pivot 38, i.e. lever 33 is moved clockwise, against the bias of spring 25 acting via rod 24, lever 27 and lever 33. After pin 35 clears the comer of projection 41, the bias of spring no longer restores pin 35 to the midpoint of extremity 42. Pin 35 is urged into opening 40 and lever 33 rotates anti-clockwise freeing end 31 of lever 27 as spring 25 urges rod 24 upward. When spring 22 (Fig. 1) which has one end anchored on rod 24 goes over centre, its force lifts bridge contact 15 off fixed contacts 13.  Lever 37 has two arms 39 opposite to projection 41 and opening 40 engaged by a moving coil 51 in opposite directions of excessive movement caused by an overload current in moving coil 51. Depression of rod 24 compresses spring 25 brings spring 22 again over centre to close the contacts and rotates the levers. Pin 35 on lever 33 moves in U-shaped opening 41 to restore lever 37 to its mid-point, so that on release of the end of the rod, the system is latched.
