Abstract: 1,204,148. Control of A.C. motors TOKYU SHARYO SEIZO K.K. 29 Nov., 1967, No. 54424/67. Heading H2J. The loading condition of an A.C. motor which drives a machine tool, is detected as a variation in the power factor of the motor, the tool being retracted, or its feeding speed reduced, if the load becomes excessive. The motor voltage is applied to transformer PT having a centretapped secondary winding supplying opposed signals A, A1 to a differential amplifier DA1 for generating square-wave pulses B, B1 to a gate AND 1. The output of the gate is in the form of pulses C which occur at each zero passage of the supply voltage. A current transformer CT is similarly associated with a differential amplifier DA2 and gate AND 2, the pulses F occurring at each zero passage of the motor current. The signal C is supplied through a delay circuit PD to a multivibrator MM whose square output waveform E has a predetermined width. The signals E and F are applied to gate AND 3 which supplies a signal to store BM provided that the pulse F occurs during the period of the pulse E indicating that the load on the motor is excessive. The output from the store is fed to element MCA for controlling the cyclic operation of the machine, the store being reset after each cycle of operation of the machine. If the motor becomes overloaded the unit MCA is conditioned to take the safety measures referred to above.

Abstract: 1,210,840. Nuclear magnetic reconance magnetometers. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 5, 1968 [Dec. 13, 1967], No.57752/68. Heading G1N. A magnetic gradiometer comprises two nuclear magnetic resonance probes 14a, 14b, each probe having decoupled input and output coils, the output coils being connected to respective inputs of an operational amplifier 16, the output from which is fed back to energize the input coils, and a phase meter 19 for measuring the phase difference between the output signals of the probes. Preferably, the Overhauser-Abragam effect is used. The operational amplifier may be a summing amplifier or a differential amplifier depending on the arrangement of the output coils in the probes and a #/2 phase shifter (30), Fig. 15, (not shown) may be included in the feedback circuit. Tuning capacitor 7 may be selectable for range changing. Details of probes and samples. Each probe may have crossed input and output coils, Fig. 1 (not shown), the samples being deoxygenated water containing nitrosodisulphonate or ditertiobutylnitroxide (DTBN). In a preferred arrangement, Fig. 5, having only one forbidden axis, each probe has two samples, the input and output coils being in two parts linked with respective samples. The input coil parts 5a, 5b are parallel with the output coil parts 6a, 6b which are connected in series opposition to compensate for parasitic fields and rotational movements. The samples may be both the same, e.g. nitrosodisulphonate or DTBN, an upper electronic resonance line (for increased absorption) of one sample and a lower electronic resonance line (for stimulated emission) of the other sample being saturated by coils energized by v.h.f. oscillators 4a, 4b, respectively. Alternatively, the samples may be different, pairs being selected so that the same frequency corresponds to an upper electronic resonance line for one and a lower electronic resonance line for the other. A single, common, v.h.f. oscillator is then used. Suitable pairs are: (a) DTBN in 50/50 water/acetone with triacetone-amine nitroxide in 70/30 water/ethylene glycol; (b) triacetoneamine nitroxide as above with tetramethyl 2, 2, 6, 6, azo 1 cyclohexanoneoxime 4 oxide 1; and (c) triacetoneamine nitroxide in pure dimethoxyethane with triacetoneamine nitroxide in 73/27 dimethoxyethane/water.

While the polymeric material may be placed between the strips as they are stacked it is preferred to anodise a strip continuously, coat it with the polymer by spraying, dip- or roller-coating and sever it into smaller strips for stacking. The anodic oxide may be porous, non-porous or a combination of these. The stack is compacted using a die which if necessary is electrically or fluid heated, or the stack may be heated by RF heating. Electrodes of opposite polarity extend to adjacent side faces and connection may be made to these by flame-spraying metal after excess polymer has been trimmed off (Fig. 8, not shown). Alternatively staples, rivets or screws may be employed. The polymeric material may be a thermoplastic addition polymer, condensation polymer, cellulosic material, polyether, polysiloxane, epoxy resin or a polymer based on a heterocyclic ring system, and numerous examples are given.

Abstract: 1,212,700. Mechanical switches. ROBERT BOSCH G.m.b.H. 29 Dec., 1967 [31 Dec., 1966], No. 59014/67. Heading H1N. A manual lever 16, an insulating body 23 mounted therein and a U-shaped member 15 can be pivoted about an axis 17 from a central neutral position in both directions to operate the direction indicator lights (32, Fig. 3), insulated parts 34 on member 15 abutting projections 33 on contact springs 28a (28c) to bring them into engagement with contact springs (29a, 29c, Fig. 2). In each of these three positions lever 16 and body 23 can be pivoted about an axis 24. Tilting upwardly from the Fig. 1 position allows a contact spring 38 to change over from a contact spring 29e to a contact spring 29d, thus switching the headlights from main beam to dipped beam, this occurring because a lug 42 on body 23 no longer depresses a pin 40 on spring 38. Detent mechanism comprising a spring-loaded ball 25 and six recesses 27a, 27b defines these stable positions. Lever 16 can be further tilted upwardly about 24 to an unstable position in which a lug 37 on body 23 abuts a projection 36 on a contact spring 286, thus bringing it into engagement with a contact spring (296) to flash the main beam. Contact springs 28a (-28c), (29a)-29e and 38 are mounted on an insulating plate 13 by connectors 43 for the connection of wires 43<SP>1</SP>. Contact springs (44 to 47, Fig. 8) are inserted in slots (48) in body 23, and their ends form eyelets (50) to which are soldered cables (51). On displacing a button 20, a handle 19 and a flexible rod 55 relative to lever 16 against a spring 59, a cam surface (56) on the end of rod 55 engages between the inner contact springs 45, 46 and causes contact spring 45 to engage contact spring 44 and actuate a horn (60). On further relative displacement against a spring 58, a cam surface 57 operates contact springs 46, 47 to actuate a horn 62.
